The present invention is directed to a selectively bendable remote access gripping tool that includes a jaw portion having a pair of jaws or nets movable relative to each other between clamped and opened positions thereof, a handle portion spaced apart from the jaw portion by a bendable central portion that has a hollow, corrugated member that is bendable, and a cord extending through the hollow bendable member that connects the jaw portion and the handle portion.
When being walked, pets frequently have the need to answer nature's call. In many instances, this requires the pet owner to “clean up” after their pet. Such activity typically occurs by the pet owner bending down and using their hands to scoop the pet waste into a plastic bag. Such a method may present difficulty for pet owners who are not flexible or able to bend in such a position. Further, some pet owners may not want to risk potential contact with the pet waste and may opt not to clean up after their pet.
Pet waste left in public areas such as streets and sidewalks creates numerous sanitary problems, particularly in metropolitan areas having high population densities. It has been estimated that there are currently 60 million dogs in the United States alone, many of which residing in large urban areas. Many municipalities have enacted local ordinances requiring that the pet owner clean up after their pets. Many dog owners resort to the “bag-in-hand” method to pick up their pet's waste. Many pet owners carry one or more plastic bags with them to collect such refuse. This entails a rather unpleasant operation that includes putting the bag on one's hand and grabbing the fecal material from the ground, carefully wrapping the fecal contents in the bag without touching the skin of the pet owner, and then having to tie the bag and either carry it in a pocket, on the leash or in a free hand until it can be disposed of.
Some longtime dog owners have resigned to this primitive method, but new owners are understandably repulsed by the above-described technique. It is therefore clear that a need exists for devices that provide clean and efficient collection and disposal of pet waste, in a convenient and sanitary fashion.
Many types of pet waste collecting devices have been devised for clean-up purposes. Some, for example, may be operated with one hand and without necessitating bending over or stooping. Such devices, sometimes called “pooper scoopers”—include those having cooperating jaws at the lower end of a relatively long, rigid cane-like handle, and some even make provision for collecting the refuse material in an open refuse bag, the refuse material entering the open end of the bag.
When pet owners take their pets for a walk, the pet owner often has at least a leash to restrain their pet and often employs a retractable leash to provide their pet with the ability to move ahead of them at different distances, while the owner retains control over such lengths via the retractable leash. Having to carry yet another tool, such as a conventional so-called “pooper scooper” device, is cumbersome and adds considerable hassle and complexity to the simple task of walking a pet. There is a long felt but unsolved need to provide a pet owner with a single tool that both provides the advantages of a retractable leash and a waste pick-up tool, such that a single device can facilitate more enjoyable pet/owner experience while on walks.
Moreover, in the area of ground and yard maintenance, whether public or private, it is often the case that garbage and debris is left on the ground or blown in by winds. For those individuals with pets or in rural areas, there is often the deposition of fecal matter by pets or wild animals roaming the grounds. As such, in order to maintain a clean and healthy environment for people, someone must periodically pick up, bag and dispose of the garbage, debris, fecal matter and other miscellaneous matter deposited on the ground. In public and business areas, this is typically accomplished by a maintenance crew, whereas in private locations it is done by the property dweller. To do this task in a sanitary and convenient way, a collection and bagging device that allows a user's hands to be distant and/or separated from the refuse and/or feces when collecting, bagging and disposing of the refuse is desirable.
In the general field of having to bend over and hand-manipulate an item, it will be appreciated that playing golf requires that a golfer repeatedly bend over to place or pick up the ball. The teeing, placement and collection of balls from the ground can be challenging for disabled or elderly players. Thus there is a need for a simple device that can be carried and transported by a golfer to make playing the game of golf easier, especially for older golfers and those with bad backs or who have limited flexibility.
The present invention relates to collection devices, and more specifically, to collapsible devices for collecting and bagging trash, garbage, debris and animal feces left on the ground without requiring the user to bend over or to manually touch the collected items. In various embodiments, the present invention is directed to a selectively bendable, hand-operated animal waste scooper that has a flexible, preferably corrugated extension, with a trigger at one end and a jaw-like scooper on the other end (e.g. having opposing claw halves), for sanitary handling of animal droppings from pets. In various embodiments, the animal scooper, waste gripping tool includes a jaw portion having a pair of jaws movable relative to each other between fully clamped and fully opened positions thereof, a handle portion spaced apart from the jaw portion by a bendable central portion that has a hollow, corrugated member having alternating ridges and grooves that is bendable so as to attain a predetermined shape.
In certain preferred embodiments, the central column of the device comprises a corrugated segment comprising a plurality of interconnected connectors, such as “loc-line” plastic elements. For certain embodiments that include the use of particular linked plastic components that comprise the flexible portion of the scooper device, incorporated entirely by this reference are U.S. Pat. Nos. 6,042,155 to Lockwood; U.S. Pat. No. 5,778,939 to Hok-Yin; U.S. Pat. No. 5,667,146 to Pimental et al.; and U.S. Pat. No, 7,533,906 to Luettgen.
In other embodiments, the hand-held waste scooper device includes a scooping portion having a scooper element movable relative to between a fully clamped position and a fully opened position. A handle portion is spaced apart from the scooping portion by a central portion, with the central portion comprising at least two separate portions comprising a hollow, corrugated member having alternating ridges and grooves. The corrugated member is bendable so as to attain a predetermined shape so that a user can preposition the central portion into a desired bent configuration. The handle portion comprises a first manually-actuatable trigger operatively connected to the scooping portion by a pull member at least substantially disposed within the central portion. Actuation of the trigger is operative to move the pull member to thereby selectively position the scooping elements between the fully clamped position and the fully opened position. The pull member preferably comprises at least one cord operatively connecting the handle portion to the scooping portion, with the at least one cord extending through said central portion. In certain embodiments, at least two separate portions of the central portion preferably comprise a plurality of interconnected connectors which together define a passageway through which said pull member passes through. In preferred embodiments, the plurality of interconnected connectors are in engagement with each other such that the interconnected connectors permit pivoting movement between the interconnected connectors.
While preferred embodiments of the present invention are directed to either a flexible fecal waste retrieval tool that can be coiled so that a pet owner can more easily carry such tool with them on pet walks, other embodiments include the inventive concept of combining a retractable leash device with a waste retrieval device. There is a current need for a pet waste collection tool having an integrated leash that is lightweight, compact, and easy to use. One of skill in the art, with the guidance provided herein, will appreciate the myriad ways by which such a combination can be achieved, but one in particular involves the combination of a retractable leash device connected to an extendable “pooper scooper”-type device. Such extension includes not only the preferred employment of at least one flexible, corrugated column portion as described herein, but also includes other telescoping mechanisms that facilitate such extension, where such telescoping mechanisms are connected to a housing of a retractable leash device. In one embodiment where a compact dual-function retractable leash and waste scooper is desired, a loc-line extended member is connected at one end to a scooper element (e.g. a pair of opposing jaw/scoops adapted to encompass fecal material when clamped together) is connected directly to the housing of a reeled leash such that mere physical manipulation of the loc-line member (e.g. from a coiled configuration to an extended position (with the coiled extension being from at least about 3 inches, more preferably at least about 6 inches in length, even more preferably 20 inches or more in length, and most preferably about 30 inches). The flexible nature of the device permits the pet owner to pre-position the angle of the scooping jaws in relationship to the ground where pet waste may reside such that a cleaner pickup of the waste can be achieved without requiring the owner to touch the waste using their hand placed in a bag. The present invention is superior to prior art “pooper-scooper” devices because the extended rigid pole that attaches to the scooper end of the device do not permit angular adjustment of the scooping section. In contrast, using the present invention, by manually adjusting the flexible portion of the extended member of the present invention, a pet owner can decide how best to approach any given deposit of pet waste, for example, by choosing to position the jaws in a manner that one jaw scrapes along the lowermost portion of the ground contacting waste, while the other jaw resides above such waste, permitting the owner to then clamp down on the jaws (via operation of the handle mounted trigger) and thus encapsulate the waste within the jaws. In preferred embodiments, the jaws are adapted to receive a bag pre-positioned about the open jaws prior to the waste recovery operation, thus achieving the desired bagging of the waste without the owner having to perform the above mentioned bag-in-hand method of waste retrieval.
In still other embodiments the issue as to what to do with the bagged waste is addressed by having the housing of the retractable leash provided with a portion that receives and dispenses bags. A bag dispenser can be of various shapes and sizes but accomplishes the basic task of providing ready access to bags for use with the scooping element of many embodiments of the present invention. Preferably such a bag receptacle is a refillable compartment that holds a plurality, e.g. about 20 biodegradable, disposable bags, able to accommodate most store purchased bag refills of both side pull (standard) or bottom pull types. For example, in combination with the associated pet waste scooping mechanism operably associated with the housing of a retractable leash, other desired features include not only flashlights, but also an associated receptacle for pet waste bags.
In certain embodiments, the bags employed have a closing ability such that once the scoop jaw of the waste gripping tool encircles the waste, with a bag pre-positioned over the scoop/jaw prior to contacting the waste, the bag is closed via the pressure applied by the perimeter of the scoop/jaw when the user operates the trigger to not only close the scoop/jaws. Certain types of closure elements can be employed to accomplish this closure function, including but not limited to adhesive being applied to one or both opposing sides of an open bag in the area where the scoop/jaws contact each other in the closed positron. Other closure mechanisms involve the use of zip-lock mating features (e.g. zip-lock bags, etc.) such that the closed position of the jaws causes the zip-lock elements of the bag employed to seal the bag with the waste contents inside.
In certain embodiments, the interiors of opposing scoop/jaw surface are fitted with a disposable liner, such as a biodegradable bag, prior to use such that the bag forms a covering to surround and encapsulate pet waste The bag protects the pet-debris scooper from soiling by pet waste during collection. The peripheral ends of the liner are attached to the outside of scoop/jaws with the peripheral edge of the disposable bag including an adhesive strip adapted to adhere the edge of disposable bag, and also may be provided to ensure a better contact and connection with one or both of the jaw/scoop features. The bag is thus positioned and retained on the scoop/jaws. As one of skill will appreciate, various other bag retention features, such as elastomeric bands, clips, etc. can be employed to secure the bag in a fashion such that it remains in contact with the jaws/scoop during the waste pick-up operation.
One aspect of the present invention is directed to effectively sealing the waste inside a bag after collection. While the above method employing adhesives is preferred, others can also be used, such as with ties, twisting of the bag, spinning the bag after it is filled with waste, etc. Thus various types of bag fasteners or closure techniques may include a wide variety of devices that clamp, seal, fasten, hold, squeeze, or otherwise close the ends of the individual portions of a bag filled with waste. Such fasteners may thus include ratchet ties, wire tie-type systems, such as a metal or wire twist tie, spring clamps, bands, adhesive tabs, peel seals, zippers, zip-locks, slider mechanisms, Velcro, or other devices to gather and hold the bag material in a tight or secure fashion.
The waste refuse collecting device as briefly described above is capable of use in picking up a wide variety of refuse, but many embodiments are designed primarily for picking up animal droppings or excrement such as may be left on a sidewalk or lawn, and when so used, it is designed to have associated therewith a disposable, excrement-collecting bag. Such device can, however, also be used to pick up a variety of other refuse without using a bag. Thus, in other embodiments, the refuse collecting device is usable for picking up a wide variety of litter without necessitating the use of the disposable bag. However, where dog or other animal excrement is concerned, or whether semi-solid garbage matter which has been spilled outdoors is to be collected, the use of the bag is highly desirable. Certain embodiments include either two movable jaws, or a fixed jaw and a pivotally mounted jaw, preferably of similar design and each being in a dished-shaped configuration.
When picking up a quantity of excrement or refuse, the flexible nature of the present invention permits a user to adjust the jaw portion to be at any desired angle to facilitate the use of one of the jaws as a scoop for sliding beneath the refuse. The refuse can then enter the reversed or inverted bottom portion of the bag and when it has thus been completely scooped or when at least a major portion of the refuse has been scooped, the operator can operate the trigger by exerting a squeezing action on the trigger, thereby causing the movable jaw to move to its closed position and the cuffed portion of the bag may be “peeled” downwardly and removed from the jaws, after which a conventional twist wire or other closure means (zip-lock bags, etc,) can be applied to the peeled portion of the bag. The bag and its contents may then be removed from between the jaws and disposed of in any suitable manner.
From the above description, it will be apparent that an extremely sanitary method of picking up refuse, particularly animal refuse, is provided, with numerous advantages that include no contact whatsoever of the hands of the user or operator with the refuse is resorted to. Furthermore, only one hand is required for the operation of the device. Still further, little or no stooping or bending of the user's body is necessary when using the device. Finally, after the excrement or refuse-filled bag is disposed of, the device remains substantially clean and does not require washing, rinsing, or the like. It may simply be put on the shelf or otherwise stored for future use by the application thereto of a fresh disposable bag. The present invention, due partially to its ability to assume a compact dimension, such as being coiled for easy transport and storage, can be carried by a pet owner in a purse, a suitcase, on airplanes, cars, buses, etc. without the problems associated with attempting to bring a conventional “pooper-scooper” rigid can-like device with them. Thus, both carrying of such a coiled device on pet walks, as well as travelling with such a device on transportation vehicles, makes the provision of such a device when desired far more practicable.
In preferred embodiments, the collecting, bagging and disposing device is achieved with a device that can be easily transported in a collapsible, bent, coiled or telescoping manner in order to have more efficient storage of the device when not in use or when transporting the device.
In certain embodiments, the device has curved jaws or clamshell scoops and an elongated handle for collecting trash and may employ a bag for the collected trash/waste material. In other embodiments, the jaws are designed such that they are able to get underneath the feces or trash in order to assure that the material being collected does not get smashed in the jaw teeth. The provision of at least one flexible portion along the member that attaches the handle region to the jaws at the opposite end, enables a user to pre-position the device for maximum effectiveness in picking up any given waste.
Preferably, embodiments of the present invention provide a one handed means for getting underneath refuse and fecal matter on the ground in order to contain the matter for removal and disposal without smashing the refuse or fecal matter in the jaws of the collection device. Another objective relates to a means for bagging the refuse and fecal matter using commonly available plastic shopping bags or specially designed pet waste bags. Yet another relates to providing a device that is collapsible (either via bending, coiling, telescoping, etc.), when not in use for convenient storage or transportation. In use, a user unfolds, extends or uncoils the shaft that extends between a handle and collection jaws, and places a plastic grocery bag, or other plastic bag in association with the jaws to secure the bag in place. The user can then place the open claw ends of the jaw e.g. claw halves, over the refuse being collected and activate the triggering mechanism of the handle to close the claw halves to encircle and encompass the waste.
Another embodiment relates to a pet waste collection tool with an integrated leash. In one such embodiment, the flexible, coiled pooper-scooper device is associated with a retractable leash.
A scoop portion attachment member is coupled to a body portion of a retractable leash, wherein the scoop portion attachment member may be either integrally connected or disengagably coupled to the body portion of the leash housing. When the scoop portion is in the closed position the curved planar regions are substantially opposed to one another to form a containment region wherein pet waste can be secured. Preferably, when the extended member is coiled and laying flat against the side of the leash housing, the jaws are maintained or retained in a closed position by a retention member, such as a clasp, so as to reduce the size of the combined leash/waste retriever device.
The present invention also relates to the field of sanitary pick-up devices for not just animal waste, but other unclean or untouchable material, trash and the like. In particular embodiments, a portable pick-up device having a storage compartment for holding a quantity of bags or wrappers is provided such that bagged pet or other waste can be transported to a convenient refuse container, toilet or sanitary area, and disposed of. Such unitary device may, for example, comprise a housing for a retractable leash, with the jaw/scoop tool associated therewith, preferably via an extendable section, like a telescoping member and/or a corrugated flexible member that renders the waste scooping features available in close approximation to the bag storage and the leash housing. A pet owner thus can leave on a walk with their pet holding a one hand-held device that provides multiple functions, including the ability to pick up waste without having to stoop or bend down and physically touch—even if only thorough a plastic bag—fresh, warm fecal matter of their pet. Similarly, it is desirable to have a clean, sanitary device for picking up unclean or untouchable material such as chemicals, solids of various kinds, small animals, specimens, temperature sensitive items, etc., in a bag or wrapper, and transporting the material or item to a convenient area, such as a refuse container, chemical bin, laboratory, etc., for deposit.
In certain embodiments, the unitary device held by a user includes not only a flexible (e.g. a member comprised of loc-line) extendable pick-up device as described herein, but also includes a supply of litter bags carried on the body of the device, such that separate bags may be withdrawn at the selection of the user.
The animal waste scooper has a preferably flexible extension that is preferably adapted to be reversibly coiled such that when it is uncoiled, the trigger operated jaws/scooping portion of the device can be employed to pick up waste and subsequently or immediately place the waste into a bag. The scooper preferably includes a handle with a trigger, an extension assembly having at least one portion thereof that has a flexible, bendable section, and a pair of jaws. Preferably such jaws are adapted to accommodate a bag such that a pet owner does not need to place their hand into a bag to recover their pet's waste.
In use, the jaws are closed by pulling on the trigger. An ordinary plastic shopping bag or other pet waste bag is opened, inverted, and placed over the jaws, the sides of the bag being retained over the jaws by adhesive, by retainer clips or any other suitable bag retention mechanism that is adapted to have the bags associated with the ends of the jaws. The jaws are then positioned over the animal waste, the trigger is pulled, and the closing the jaws enclose the animal waste in the plastic bag.
As described above, in one embodiment, the extendable waste scooping device is attached to a retractable leash housing. Preferably, separate finger or thumb operated triggers are provided to operate the brake components of the leash, with a separate trigger component provided to operate the closing of the jaw/scoop portion of the device. While one of skill in the art will appreciate the many design variations as to the number of triggers to employ to operate the various functions of such a unitary hand held device, in one embodiment, the handle of the retractable leash has the brake component positioned for operation by a user's thumb, while the scoop/jaw closing trigger is provided inside the handle portion of the leash, and is operated by an user's index finger. Thus, in one embodiment, a retractable animal leash assembly includes a housing which is carried in one hand and a leash is coiled within the housing. A brake for the leash is operable by a user's carrying hand into an activated position to hold a portion of the leash located outside said housing at a desired length. A flexible, articulated member is connected to the leash housing and is preferably coiled on the exterior of the housing so that a user can easily physically stretch out the member to an extended position such that the scoop-like jaws are positioned at a distance from the housing. A disposable bag is preferably placed over the scoop/jaw portion of the device in a manner such that the bag is retained thereon in a manner that enables the user to lower the device to the ground, where a pet deposit resides. The user then can position the open jaws—now having a bag covering such jaws—over the pet waste. Operation of the trigger then causes the jaws to close, thereby encircling the waste within the confines of the jaws, in such a manner that the bag is brought into contact and encompasses the waste. Accordingly, it is a principal object of the invention to disclose an animal waste scooper that has a flexible portion thereof, preferably a corrugated member, and most preferably one made of loc-line material, such tool adapted to pick up animal waste and to enclose the waste in plastic bags for disposal.
A scooping assembly in accordance with the present invention thus includes a pair of jaws fashioned into scoops that are adapted to encircle pet waste (e.g. with tines, teeth optional) adapted to scoop up and dispose of pet droppings and at least one triggering member operatively coupled to the jaws/scoops together to scoop up the pet droppings, with the jaws/scoops attached to flexible lengths of material that are covered by a flexible film that adds stiffness to the flexible length.
Various embodiments incorporate the use of a refuse collecting bag which is disposable after it has been filled. In preferred embodiments, two relatively movable, complemental, coacting, pick-up jaws are carried at the lower end of an elongated flexible member, preferably at least one portion thereof being corrugated and/or comprised of linked ball and socket jointed elements, and in some embodiments also telescopically adjustable into a locking length, with the jaws shaped and designed to scoop pet excrement from the ground without a user having to bend over and contact such waste via their hands. The scoop jaws are preferably designed so that it may be used in scoop-like fashion for picking up excrement, but in some embodiments, a movable and a fixed jaw construction can be employed such that the movable jaw may be used as a reverse paddle to force excrement into the scoop-like jaw. Alternatively, by holding the device in a substantially vertical position, the usual pincers-like action of the two jaws may be used for excrement pick-up purposes. In other words, the flexible nature of the extended member enables the coiling of the member for easy carrying, while in use, the member may be straightened when picking up waste, thus resembling a conventional pooper-scooper device when in pick-up mode.
Thus, certain embodiments of the present invention include a pair of jaws/scoops that are connected to and employ a flexible extension (e.g. one that can be coiled to facilitate easy carrying by the pet owner on a walk), and more preferably include the ability to have a bag placed over such jaws/scoops such that a pet owner can pick up waste without using their hand (even if such hand is inside a plastic bag). Other embodiments are directed to a retractable animal tether that includes a flexible, extendable pooper-scooper device attached thereto (or integral therewith), such combined tool comprising a hand-held support; a spool rotatably mounted on the support; a flexible cord wound on the spool; and a reversibly coiled extendable member that can be bent or straightened from an initial coiled configuration into an extended configuration, with a jaw/scoop positioned at the end of such extension.
Various embodiments the present invention are directed to a device for scooping up animal waste and sealing it in an ordinary plastic film bag. Such a device includes a flexible, extendable portion, preferably comprising a corrugated flexible tube(s) that facilitate one handed waste retrieval operation at a distance from the waste. At one end of the handle is a pair of reversibly openable and closable jaws. The closed end of a bag is releaseably secured between the jaws. The open end of the bag is everted over the free edges of the jaws. The open jaws with the open bag stretched between is then placed over the waste and when the jaws/scoops are closed via operation of the trigger mechanism on the handle a the other end of the device, the waste is scooped into the bag. The edges of the bag are then removed from the jaws and preferably sealed, e.g. with a tie, adhesives, twisting, etc. A locking mechanism can be provided to keep the jaws closed until ready to dispose of the sealed bag. The opening and closing and locking of the jaws may be performed with one hand by an operator mechanism located away from the jaws. Preferably a trigger is provided that separately operates the jaws after the flexible portion is extended to reduce if not eliminate the need to stoop to reach pet waste on the ground.
Thin film polymer bags are inexpensive, somewhat resilient, impermeable to moisture and odor, and readily sealed with a twist tie. One embodiment of the present invention is directed to a method and system to encapsulate the feces in one of these bags without soiling the outer edge of the bag, while the user is at the other end of a long handle. The present invention avoids the unpleasantness and indignity to which many dog owners are now subjected when they use their bare hands inside plastic bags to grasp fresh pet manure. It is accordingly an object of the invention to provide a device for picking up animal waste that keeps the operator relatively remote from the waste during the pick-up process and that packages the waste into an ordinary inexpensive plastic film disposable bag.
In one embodiment the device of the invention comprises a pair of jaws pivotally attached to one end of an extended loc-line extension, with the device being coiled to facilitate transport by a pet owner and providing a way for such device to be carried in suitcases, purses, etc. when traveling so as to provide ready access by a pet owner to a pooper-scooper device. In such an embodiment, the jaws in the open position are fitted with a thin film plastic bag while the open end of the bag is everted over the edges of the jaws. The device is now prepared for one handed operation. To pick up the owner's dog feces, the user positions the open bag over the waste, makes jaw contact with the ground, operates the trigger of the handle to close the jaws and encloses the waste within the bag. The jaws may be locked closed to continue the walk by, for example, having the trigger remain in a position so that the jaws remain closed. In a preferred embodiment, however, the bag is sealed after or upon the closing of the jaws such that the bag is removed from the jaws and sealed, such as by a lock seal or twist tie and the sealed bag is disposed of.

While a standalone flexible waste scooper is one embodiment of the present invention, it is believed that many pet owners only desire to carry with them one simple multifunctional device when walking their pets. Thus, in several embodiments, a combination of pet walking tools is provided to address this desire. One aspect of the present invention is therefore directed to a portable, retractable animal leash assembly, wherein the leash line is arranged on a wind-up spool mounted to rotate in a housing carried in the hand. The assembly preferably includes a brake having brake operable by the carrying hand to stop the portion of said leash line wound off a spool at a desired length, with a brake lock mechanism being associated with the leash to lock the leash in the position momentarily determined by the brake. A flashlight feature may also be incorporated on the device, as well as a bag holder. Thus, in certain embodiments, a hand-held apparatus is provided which dispenses, retracts and locks an animal leash in a desired position. Such a device comprises a hand-held leash housing formed to include a spool and having a handle portion. The spool housing rotably mounts a spool having a length of cord wrapped thereabout with the distal end of the cord being adapted to be attached to an animal collar. A coil spring is mounted between the spool and spool housing to continuously bias the length of cord in a retracted position about the spool. A high strength locking mechanism adapted to selectively apply friction to the spool and, hence, positively prevent the cord from being dispensed or retracted from the spool is provided which is actuable by way of a trigger lever formed on the handle portion of the device. A cam actuator stop is additionally provided to permit the locking mechanism to be easily maintained in a locked orientation. The handle portion is preferably provided with a trigger mechanism that operates the jaw/scoop end of the flexible, extendable device. Such trigger is preferably separately located in the handle portion such that a user can separately operate the leash retraction mechanism and the scooper mechanism at desired times. The provision of both a retractable leash combined with a fecal retrieval tool is believed to be particularly attractive as a pet owner desires as few implements as possible to carry on a walk with their pet.
With respect to retractable leash embodiments in combination with the flexible, adjustable pooper scooper tool, the following are all incorporated herein by reference in their entireties to provide sufficient written description and enablement options of the present invention: U.S. Pat. Nos. 8,528,850; 6,148,773 to Bogdahn; U.S. Pat. No. 4,501,230 to Talo; D439,402 to Plewa; and U.S. Pat. No. 6,648,261 to Irving.
The specification describes a hand-held gripping device, and in particular a pet waste retrieving device, comprising a jaw portion having a pair of jaws movable relative to each other between fully clamped and fully opened positions thereof, and a handle portion spaced apart from the jaw portion by a central portion, which in some embodiments may be adjustable in length via telescoping portions slidingly moved to attain a desired length. The handle portion comprises a manually-actuatable trigger (although in other embodiments the activation of the trigger is via an electronic button) operatively connected to the jaw portion by a selectively extendible pull member at least substantially disposed within the central portion. Actuation of the trigger is operative to move the pull member to thereby selectively position the pair of jaws between the fully clamped and fully opened position thereof. The selectively extendible central portion may comprise a first tubular member and, if the device is adjustable with respect to its length, may employ rotatable locking members to reversibly lock the respective portions of the central column into a fixed position. In certain embodiments, the central portion comprises a hollow, corrugated member having alternating ridges and grooves, such member being bendable so as to attain a predetermined shape. Suitable material for use in the central column will be known by those of skill in the art, but, for example, hoses used for connecting gas appliances, such as coated, stainless steel gas connector hose is suitable for many embodiments as it reversibly bends via simple manual adjustment (or in certain embodiments, via a separate trigger element) into various desired directions and retains its bent position until further altered by the user. Alternative materials can be selected for various desired attributes, such as weight, cost, color, temperature characteristics, rigidity, corrosion resistance, electrical conductivity, water permeability, glow in the dark characteristics, etc. Thus, suitable connector material for use as the entire, or alternatively only a portion of the central portion of the gripping device, may comprise a hollow, corrugated member having alternating ridges and grooves, such member being bendable so as to attain a predetermined shape, and may be made of a variety of materials, including plastic, metal, and composites. The bendable portion of the central portion can be selectively or in a predetermined manner configured into a shape so as to facilitate easier access to a desired area, object, etc. The reversible nature of the bendable nature of the tool provides a user with the ability to adjust the angle of the distal portion of the tool to accommodate the myriad of difficult angles encountered by a user. Traditional remote access tools, which have straight and non-bending (as opposed to merely pivoting or telescoping) portions, are not able to achieve the desired remote access as provided by the present invention.
Extendable tools are typically used to interact with overhead objects that may be close or remote. For example, a fruit picker may be able to reach fruit; a janitor to replace light bulbs, and elderly person to grasp objects near their chair, tree pruners to reach certain limbs in particular orientations, etc. All of these various functions are made vastly easier by the provision of applicable forms of embodiments of the present invention as described in more detail (with respect to illustrative embodiments that one of skill in the art will appreciate transcend the particular field employed for illustrative purposes.)
In certain embodiments, at least one cord is employed that operatively connects the handle portion to the jaw portion, with such at least one cord extending through said central portion and through the hollow, corrugated member having alternating ridges and grooves. In certain embodiments, only the distal portion of the device has a segment of the hollow, corrugated member so as to limit the weight characteristics of such material as compared to the overall device. In certain embodiments, the hand-held gripping device has at least ⅔.sup.rd of said central portion comprises said corrugated member. It has been found, however, that providing ten inches of such material is sufficient for many circumstances where a user desires to perform the desired bend to facilitate reaching an object to engage with the jaws of the device. As one will appreciate, however, any length of the hollow, corrugated member having alternating ridges and grooves can be used depending upon the circumstances. Thus, while in some embodiments, substantially the entire central portion comprises such material, in other embodiments; one or more sections of the central portion comprise such a hollow, corrugated member. In certain preferred embodiments, the distal portion has at least 1 inch of such hollow, corrugated member, more preferably at least about 3 inches of such material, and most preferably at least about 6 inches of such material. In other embodiments, at least two portions of the central column have sections with such hollow, corrugated member such that a user can preposition each section for a desired bent configuration, thus permitting the ability to reach an object remote form the user that may be difficult or impossible to reach using traditional gripper devices with straight central columns.
In certain embodiments, the hand-held gripping device employs a handle portion that has a second manually-actuatable trigger, with such second trigger able to adjust the orientation of the distally positioned jaw portion by effecting a change in the shape of the one or more corrugated members along the extent of the central portion. In some embodiments, the trigger that functions to alter the bending of the corrugated member is a rotatable knob, such that many varied angular orientations of the distal end (with the jaws) can be attained via rotation of a knob positioned near or on the hand grip of the device. Electronic means can also be employed for such purpose, as well as for the operation of the jaws between their closed and open positions.
While certain embodiments solely employ at least one section of a corrugated member to achieve desired bendable characteristics, other embodiments of the hand-held gripping device have a portion of said central portion that is in telescoping relationship with an adjacent portion of said central portion. Telescoping shafts may have two or more shaft members so long as each inner member is slightly smaller in cross-sectional area than the next outer member. In such embodiments, a locking member associated with said central portion is used to fix two adjacent members of said central portion in an engaged position, with the locking member operable between a first locking position and a second unlocking position. The locking member may comprise a coupling member, such as rotatable collar that can be manipulated by a user to adjust the griping member's length. In one embodiment, a section of corrugated hollow material is positioned at the distal end of the device, about 3 to 6 inches away from the jaws (and in the direction of the hand grip) and two adjacent members of the central column portion are operatively associated with each other in a slidingly telescoping relationship with a locking member is associated with at least one of said two adjacent members, the locking member comprising a selectively radially expandable mandrel radially expanded into engagement with the adjacent members to permit the length of the central column member to be varied.
In preferred embodiments, a pull member comprises first and second pull rods and a cam body supporting a cam is used, with the pull rods associated with the cam support body. The cam is characterized by a first, engaged condition in which the cam is in contact with the second pull rod to thereby fix the length of the pull member, and a second, disengaged condition in which the cam is out of contact with the second pull rod to thereby permit the length of the pull member to be varied. The user-actuatable trigger comprises a manually operable release trigger provided on the handle portion, which is, operatively connected to the cam via a connecting rod.
One of skill in the art, especially guided by the incorporated references, will appreciate the varied types and features of gripping devices that can be constructed and that further incorporate the hollow corrugated member(s) as described herein in order to attain desired bendable capabilities of a particular user. For example, and without limitation, the present invention can be employed in a variety of fields where the problem of access around otherwise difficult angular orientations is presented, such fields including but not limited to the following: fruit pickers; janitors replacing light bulbs, elderly persons grasp objects near their chair, tree pruners; surgeons and dentists/orthodontists to reach interior portions of a person's anatomy, etc.
While preferably the bendable portion of the central column is made of a corrugated material (due to its ability to remain open in its central internal core, thus permitting pull cords to operate therein), those of skill in the art will appreciate that—especially dependent upon how severe and desired bending may be—that other types of bendable segments can be employed to achieve such a function. For example, pliable plastic or rubber-type sections can also be alternatively or in conjunction employed on a gripper device of the present invention so as to achieve the ability of a user to reach objects that would be difficult or nearly impossible using a device having a straight and non-bendable column. Of course, the ability of such a section to uphold the weight of the jaws, especially after the jaws have grasped some desired object, is an important consideration when selecting appropriate materials to employ for the bendable portion of the column. In other words, a sufficient amount of rigidity and/or operational integrity of the central column is required for most applications.
In still other embodiments of the present invention, one or more springs can be employed (with such spring(s) having desired structural integrity with respect to an ability to bend, an ability to support weight that may be encountered when the jaws engage an object and the device is lifted in the air, etc). Thus, in one embodiment, a section of spring is used along the central portion of the device with a cord mechanism that is attached to the jaw end of the device, such that when the cord is pulled, the spring section bends to angularly adjust the jaws such that they can reach around corners otherwise inaccessible with a straight column gripper device.
To comply with appropriate written description and enablement requirements and to provide sufficient guidance in how one of skill in the art can make and use the various and numerous embodiments of the present invention, incorporated herein in their entireties are the following: Hsu, U.S. Pat. Nos. 6,513,844; 6,520,556, 6,739,637, and 4,669,769 to Polder, Jr; U.S. Pat. No. 4,962,957 to Traber; U.S. Pat. No. 8,061,751 to Hatcher; U.S. Pat. No. 7,934,756 to Kroeze; U.S. Pat.

No. 5,590,923 to Berger et al.; as well as U.S. Pat. No. 4,962,957; U.S. Pat. No. 4,709,839; U.S. Pat. No. 3,527,492; U.S. Pat. No. 4,613,179; U.S. Pat. No. 4,669,769; U.S. Pat. No. 6,257,634; U.S. Pat. No. 7,004,520; U.S. Pat. No. 6,513,844; U.S. Pat. Nos. 6,571,479; 6,042,155 and U.S. Pat. No. 6,848,731.
Some extendable tools have fixed tool heads, e.g. a dust mop, or a flexible tool head, e.g. a device for swapping out light bulbs that has spring-like fingers. Other extendable tools include a hand powered actuatable tool head assembly having movable elements, such as, but not limited to, a tree pruner. In other embodiments, extendable tools have an actuatable tool head assembly that have drive assemblies in order to allow the user at the bottom end of the extendable tool to actuate the tool head at the upper end of the extendable tool. While an actuatable tool head assembly associated with one end of an extended tool may be any type of tool, and while the present discussion relates in particular to a tool having a jaw assembly as an example, more specifically a reaching tool that may be used to grip objects between the two jaws, it will be understood by those of skill in the art that various known tool head assemblies can supplant the discussion of clasping jaws and thus, will otherwise suffice to describe the novel and non-obvious aspects of the present invention in such other embodiments and functions.
Thus, as opposed to the prior art, where materials employed for the central column were hardened plastic polymers or any of substantially non-malleable metals, the present invention can be seen as distinctly different as it relates to employing materials and constructions that bend or otherwise flexible so as to achieve the functional attributes that the prior art devices cannot achieve.
Other embodiments have a more ball-cupping jaw/claw portion and when uncoiled, can be extended a great extent (over 10 feet, etc.) so that a golfer is able to easily retrieve balls hit into the water or rough. In still other embodiments, one device having the handle 40, trigger 41 and flexible central portion 30, is adapted to have replaceable and disenagagable distal end portions such that a user can achieve a myriad of different desired operations simply by removing and replacing end tools that have complementary detachable housings associated therewith that interact and reversibly connect to the non-handle end of the tool.
Another aspect of the present invention is directed to a double headed fishnet which creates a trap or cage to allow the user to easily catch fish, especially in a fish tank, but in other embodiments, useful for sport fishermen, fish farming operations, etc.
Cleaning a fish tank often requires that the fish residing within be temporarily removed and stored in alternative tank while their primary fish tank is being cleaned. To catch and remove the fish from the fish tank, a wide range of fishnets designed specifically for that purpose have been developed and produced. These fishnets are also used in pet stores when a person purchases a new fish for their fish tank. The pet store worker must capture the often specifically chosen fish for the customer and secure that fish in a bag for transport to the customer's fish tank. This can be extremely difficult with a traditional one headed fishnet as fish can be particularly agile. Thus, one object of the present invention to provide an apparatus which facilitates the swift and easy capturing of fish in a fish tank. In some embodiments, the present invention utilizes a dual headed design that is capable of opening and closing. In other embodiments, a side skirt net is used to close off three sides of the net end of the apparatus in addition to the two sides of the dual net heads. This configuration makes sure that only one side (the front) of the six sided net end is open, closing off any route of escape for the fish, making it very easy for a user to catch fish by simply lowering the net end directly down around the fish and closing the apparatus, allowing easy removal of the fish from the tank.
Generally is not desirable for users to touch the fish with their hands when the fish are transferred, such as when the tanks are cleaned. With at least some known fish nets, depending on the size, strength, and/or activity level of the fish, for example, a risk exists that a fish may leap, wriggle, or otherwise escape from the net as it is being transferred from one aquarium to another. Depending on the size, speed, and/or activity level of the fish, capturing a fish in such a net may be a time-consuming and/or difficult task. Thus, in one embodiment, net assemblies are moveable from a closed position wherein the first net assembly is positioned in contact against the second net assembly, to an open position wherein the first net assembly is positioned a distance away from the second net assembly.
Using the present aquarium tool, a user can safely and quickly transfer fish from one location to another with a single hand and in such a manner that the risks of the netted fish undesirably exiting the net are reduced in comparison to known fish nets. More specifically, the fish net includes a pair of net assemblies. The frames of each net assembly are configured to contact in a mating relationship when the jaw portion is moved to the closed position. The mating relationship of the frames substantially prevents the netted fish from exiting the fish net. As a result, a fish net is provided which facilitates reducing the risk of a netted fish from inadvertently escaping the captivity of the fish net in a cost-effective and reliable manner.
In one embodiment of the present invention, the jaw portion of the flexible reacher is adapted to provide at least one fish net assembly such that at least one, but preferably both of the movable jaws is designed so as to have a net associated therewith, preferably where each net assembly has a rim which reversibly contacts an opposing net assembly (when the trigger is operated). This achieves a net closing function, e.g. such that fish can be encompassed within the movable jaws of opposing net material, enabling a person attempting to catch/net a fish in an enclosure, such as an aquarium. One can position the opposing net structures in a region where the desired fish is located, whereby the operation of the trigger causes the two opposed nets to move closer together into a fully closed position, which co-aligns the outer rim portions of opposing nets, thus providing a way to encircle and trap a fish in a net without having to move (as is traditionally done) a single net structure to the surface to entrap the fish.
The ability to pre-bend the aquarium fish net tool provides one who wishes to net a particular fish with the ability to approach a fish in a typical tight hiding place inside an aquarium, where fish reside when scared or wary. Thus, when a desired fish moves to a presumably safe place under a rock cliff of an aquarium or in a fashioned underwater cave—using the present invention one can place the opposed fish net in position in the cave or under the cliff, where the fish is likely to move once startled—thus providing a far quicker way in which to net such fish.

No. 5,822,908 to Blancard, which are generally directed to types of suitable fish net structures that may be employed in the manufacture and use of the various embodiments of the present invention, as well as U.S. Pat. Publication no. 20140054912 to Bustos and U.S. Pat. No. 7,677,619 to Hutchings for particular features, such as inclusion of lights, magnets, etc. in conjunction with the claimed device.
One will appreciate that this summary of the Invention is not intended to be all encompassing and that the scope of the invention nor its various embodiments, let alone the most important ones, are necessarily encompassed by the above description. One of skill in the art will appreciate that the entire disclosure, as well as the incorporated references, pictures, etc. will provide a basis for the scope of the present invention as it may be claimed now and in future applications.
Other advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered with the accompanying drawings, wherein:
It will be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale, some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention. For the following description, the actuatable tool head assembly is described as a gripper having a jaw assembly 11. It is understood, however, that any type of actuatable tool head assembly may be used.
As disclosed in the figures, various embodiments of the present invention generally comprise a hand-held gripping device having a jaw portion (indicated generally at 10) comprising a pair of jaws 11a, 11b and a handle portion (indicated generally at 40) spaced apart by a selectively extendible central portion (indicated generally at 70). The handle portion 40 comprises a manually-actuatable trigger 41 operatively connected to the jaws of the jaw portion by a pull member. Actuation of the trigger 41 is operative to move the pull member to thereby selectively position the pair of jaws 11a, 11b between fully clamped and fully opened positions thereof. It will be understood that the jaw construction and the handle portion construction is intended as exemplary only, and that those of skill in the art will appreciate how to adapt such portions as desired, consistent only with facilitating operation of the bendable column gripping device as hereinafter described.
A pull member is interconnected with the jaw and handle portions such that manual actuation of the trigger 41 effects movement of the jaws 11a, 11b.
In certain embodiments, the user-actuatable release trigger 41 of the present invention comprises a release button 42 disposed on the trigger 41 of the handle portion 40. In the event that the distance between the jaw portion 11 and the handle portion 40 is not appropriate in light of the task contemplated by the user, the user may adjust the length of the central portion by first unscrewing a collet assembly 80 to thus permit telescoping movement of first and second tubular members. The user next actuates the release trigger, either by depressing the release button or turning the collar (depending on the form of the invention), which actions cause the second coupling to move from the engaged to the disengaged position. At this point, the pull member may be lengthened or shortened concurrently with telescoping movement of the first and second tubular members. Thus, while depressing the release trigger 42, the user grasps the second tubular member and changes the distance between the handle portion and the gripping portion as desired. After the desired length is obtained, the user releases release trigger and tightens the collet assembly to thereby fix the lengths of each of the central portion and the pull member.
Selective positioning of the first and second tubular members may be effected by rotational movement of one of the first or second tubular members of the central portion.
In certain embodiments, the gripping device of this embodiment comprises a selectively extendible central portion 70 including a first tubular member 71 slidingly telescopingly received within a second, larger-diameter tubular member 73. In order to fix the relative positions of the first 71 and second 73 tubular members, there is provided a collet assembly 80.
A locking mechanism 42 may be provided to fix the pivotal position of the trigger 41, and thereby fix the relative positions of the jaws 11 between the fully open and fully closed positions thereof.
In operation, from the position wherein the jaws 11 are fully opened, a user manually depresses trigger 41 to retract the pull rod 50 and thereby move the jaws 11 toward each other.
To understand and appreciate the varied and numerous applications of the present invention in the context of tools that do not employ the gripping jaw device used as an illustrative example herein, the inventors incorporate by reference herein, in their entireties, the following patents to provide the detailed embodiments that, with the features here described, facilitate far easier access to previously difficult to reach areas so that the various functional assemblies at the remote end of a tool can be used effectively:

It will be appreciated from the above disclosure that the present invention improves upon the prior art by providing a bendable gripping device that is robust yet simple in design, and that allows easy adjustment of the direction of the jaws 11 to reach around tight corners or other places where a straight columned device would simply not function to retrieve desired objects remote form the user.
In one embodiment, a hand held gripping device is provided that has a jaw portion comprising a pair of jaws 11 that are movable relative to each other between fully clamped and fully open positions. A handle portion 40 is spaced apart from the jaw portion 11 by a selectively extendable portion, the handle portion having a manually actuable trigger connected to the jaw portion. An extendable pole member, preferably running longitudinally through a tubular section, operatively connecting the jaw portion 11 to the handle portion 40, is provided. Actuation of the trigger 41 is therefore operative to move the pole member to selectively position the pair of jaws 11 between fully clamped and fully opened positions. Between the jaw portion 11 and the handle portion 40 is therefore a central portion, preferably comprising a hollow, corrugated member 30. Such corrugated member 30 preferably has alternating ridges and grooves such that the central portion of the device is able to bend in order to attain predetermined shapes. In particular embodiments, at least one cord is connected between the handle portion and the jaw portion 11, such that the cord extends through the central portion of the device.
As illustrated in
In other embodiments, a user actuable trigger 41 comprises two operable triggers with the operation of a first trigger 41 causes the reversal opening and closing of the jaws 11, whereas the other trigger (not shown) causes the distal end of the device to move such that the distal end bends in relationship to the longitudinal axis of the device.
In other embodiments, a selective positioning of a knob (not shown), such knob position near the trigger/handle portion of the device, is provided in order to cause rotational movement of the distal end of the device through manual adjustment of the knob.
In still other embodiments (for example,
As described above and herein, various embodiments of the present invention are directed to so-called “pooper-scooper” type devices, with the advantage being that a pet owner can more easily carry and transport such a device due to the various flexibility, bendability and adjustability characteristics of the many versions of the present inventions. Thus,
In certain embodiments, including the movable jaws embodiments in
In more general embodiments, the present invention is directed to a hand-held reacher for gripping an object and includes a handle portion 40, a jaw portion 10, and a shaft extending between the handle portion and the jaw portion, with such extended portion including at least one section that is flexible 30, preferably corrugated and most preferably constructed of loc-line-type articulated joints that have hollow interiors to facilitate a cord extending through the interior of the flexible corridor formed. At one end of such a device there is at least one jaw/claw portion 11 having at least one of the jaws 11 moveable between an open position and a closed position, and the handle portion 40 having a manually-operable trigger 41 for moving the jaws 11 between the open and closed position. An additional locking member 42 for releasably locking the jaws in a closed or partially closed position is also a feature of preferred embodiments.
In still other embodiments, the present invention is directed to a hand-held gripping device having a jaw portion 10 that includes a pair of jaws 11 movable relative to each other between fully clamped and fully opened positions. A handle portion 40 is spaced apart from the jaw portion 10 by a selectively extendible central portion, with the handle portion including a first manually-actuatable trigger 41 operatively connected to the jaw portion 10 by a selectively extendible pull member at least substantially disposed within the bendable, preferably corrugated central portion 30. Actuation of the trigger 41 is operative to move the pull member to thereby selectively position the pair of jaws 11 between the fully clamped and fully opened positions. The central portion can be constructed of various materials, including ball-and-socket connectable members of varying lengths, diameters, etc, with such members having a hollow, interior through which a cord or wire can extend through, thus connecting a handle portion 41 to a movable jaw portion 10 of a device. Preferably such a corrugated member 30 has alternating ridges and grooves, which may be covered by an outer sheath of preferably flexible material, such as rubber, fabric or plastic, with the corrugated member 30 being bendable so as to attain a predetermined shape.
In preferred embodiments, the corrugated member 30 is made of loc-line connected elements that have ball and socket connections that permit substantial flexibility of a connected length thereof. A pull member, such as at least one cord, is operatively connected to the handle portion 40 at one end and to the jaw portion at another end of the device. The cord extends through and is preferably entirely encompassed by the central portion. The corrugated member 30 has a first configuration whereby prior to actuation of the actuation trigger 41, the pair of jaws 11 is in the fully opened position and the corrugated member is bent. A locking member 80 may be operatively associated with the central portion so that two adjacent members of the central portion can be moved with respect to each other in a slidingly telescoping relationship and can then be locked into place. The locking member 80 may be a selectively radially expandable mandrel, radially expanded into engagement with the adjacent members to permit the length of the pull member to be varied. The corrugated member 30 is preferably constructed of plastic and is able to be bendable so as to attain a predetermined shape.
In certain embodiments, at least two portions of the central portion column are made of hollow, corrugated members 30 such that a user can preposition each of the portions for a desired bent configuration. The central portion comprises at least 6 inches of the hollow, corrugated member 30 and two or more corrugated members may be provided at different relative locations along the central portion of the device. Preferably, at least two thirds of the central portion comprises the bendable portion that is adapted to be coiled to facilitate transportation and storage, and further includes a locking member operable between a first locking position and a second unlocking position. The actuatable trigger 41 preferably includes a manually operable release trigger 41. The central portion in certain embodiments also includes a bendable portion made of rubber.
One particular aspect of the present invention is directed to the playing of golf. Playing golf requires that the golfer is able to pick the ball up from, and place the ball on to the playing surface, and further requires the ability to tee up a golf ball. The teeing, placement and collection of balls from the ground normally requires that the golfer bends, which can be challenging for disabled or elderly players. Thus certain embodiments of the present invention are directed to a golf ball retriever device, while others are directed to grasping a golf ball and preferably also an associated golf tee, such that the ball and the tee can be planted into the ground so that a golfer can tee off. The present invention thus provides a way for a golfer to avoid having to bend down to place his/her teed ball, thus being of considerable benefit to old golfers and those with bad backs or having limited flexibility.
According to certain embodiments of the present invention, a hand operated device for grasping a golf ball from the ground from a standing position is provided where the device includes a flexible, preferably corrugated extendable member 30 having a triggered handle 40 at one end and at the other, a jaw/claw assembly 10 such that a golf ball can be grasped and manipulated.
As discussed herein in further preferred embodiments, a stabilizer 60, 61 for stabilizing the device during teeing of a golf ball is provided, with such stabilizer preferably made from similar material as the main extendable member: e.g. loc-line elements connected together that are flexible. Thus, when such flexible stabilizer 61 is secured adjacent to and substantially parallel with the main extended member of the device, such as about 8 inches or so form the jaw/claw end 10 of the device, it is able to extend to reach the ground to achieve desired stability during the teeing operation. The short arm 61 is readily and easily bent out of the way when the golfer does not need such stabilizer function. Manipulating of a golf ball may comprise picking the ball up from the ground; and/or placing the ball on the ground; and/or inserting the golf tee with ball associated therewith object at least partly into the ground. In preferred embodiments, the manipulator includes a gripper 10 with opposed pivoting jaws 11.
Moreover, in addition to assisting golfers in teeing off without having to bend down to the ground, the present invention is very useful in retrieving balls that land in difficult to reach places on a golf course, such as out of bounds, in shallow water of golf lakes or ponds, in bushes, tangled trees, etc. It can further be used to place a marker and retrieve a ball once in the hole. Thus in one embodiment, a golfer takes a ball and a tee, loads them into the closable jaws/claws of the device, compresses the trigger of the device to hold the jaws around the ball and tee combination, points the tee towards the ground and inserts the tee into the ground. Using the present device, a golfer can readily unwind the coiled device, stretch it and bend it as desired to reach any ball in the rough, undergrowth, off the fairway or in the water, with relative ease and without having to otherwise bend down. After use, it can be coiled again and stowed with a golf bag or on the cart. Incorporated herein by this reference are the following references to further assist in complying with written description and enablement requirements: U.S. Pat. No. 6,971,695 to Backstrom; U.S. Pat. No. 5,707,303 to Berkowitz, et. al., U.S. Pat. No. 8,529,37.9 to Faircloth; and U.S. Pat. No. 8,602,917 to Bennett.
In one embodiment, a stabilizer feature 60 is employed with the flexible jaw/claw device 10 described herein for the purpose of assisting in stabilizing the placement of a golf ball on a tee into the ground for a golfer to tee off. Thus, in one embodiment, the stabilizer 60 comprises a ground engaging foot and a resilient member to urge the foot to an extended position. The stabilizer 60 may be connected to the lower portion of the extended member so that when lowered to the ground, contact the ground to stabilize the ball placement operation are arranged such that the foot engages with the ground, and as the manipulator is moved towards the ground against the urging of the resilient member, the foot remains engaged with the ground to stabilize the device while the control mechanism is operated to manipulate the object. In a preferred embodiment, the cost and expense and complexity of a spring loaded pogo-stick-like element 60 is avoided in favor of a length of loc-line hose 61 that is associated with the main loc-line member connecting the handle and the jaws/claws 11. Thus, about 6-10 inches of preferably ¼ inch diameter loc-line (although ½ inch loc-line may also be used) is connected to the main loc-line member (preferably comprised of ½ inch loc-line due to its more stable characteristics—and ability to convey the downward forces from the handle to the ground exerted by a golfers pressing in his/her tee) to act as a short, stabilizing, ground contacting extension. When a golfer presses down on the tee with the device, the ¼ inch loc-line bends due to the contact with the ground, thus providing just enough resistive force to stabilize the tee placing operation without hindering the same. Also incorporated herein by this reference is U.S. Pat. Publication No. 20130130842 (application Ser. No. 13/673,032) to Bennett. Thus, in other embodiments the stabilizer 60 comprises a piston arranged to move axially within a tube which, in use, is secured to the flexible shaft member 30 of the device, extending substantially parallel with the shaft. A ground engaging foot and a resilient member is provided to urge the foot towards an extended position.
While in a preferred embodiment, the jaws/claw 10 is designed and adapted for holding a golf ball and a tee, in others, it may just hold a golf ball alone—and in still others, just a tee alone. Preferably, however, the jaws/claws 11 accommodate insertion of the tee with the golf ball resting on it. In various embodiments, the distal end portions can be substituted with differently configured mechanisms, such as the replacement of a gripper jaw end with a pooper-scooper end or a golf ball gripping device. Thus, in certain embodiments, with one device having the handle 40, trigger 41 and flexible central portion 30, one can achieve a myriad of different desired operations simply by removing and replacing end tools that have complementary detachable housings associated therewith that interact and reversibly connect to the non-handle end of the tool.
For example, an departing from a strictly movable jaw member embodiment, certain embodiments of the present invention are directed to a golf ball cupping member (as depicted in
In one embodiment, as depicted in
As can be seen in
Other embodiments of the present invention relate to a much smaller version of the device as described above, such a device finding use in a surgical environment and other places and situations where very small dimensions are required to fit through spaces, such as lumens, vascular spaces, internal body cavities, etc. Thus, in certain embodiments, the selectively bendable remote gripping tool has relatively small dimensions so it can be easily inserted into the body through known guiding catheters.
Various instruments are known in the art for removing various objects 50 from the body, such as instruments used for removal of stones such as kidney stones, gallstones, blood clots, thrombus clots, occlusions, calcinated plaques, urinary stones or stones of the bile duct; for removing foreign articles from the vascular system of a patient or from a body duct or orifice, such as the ureter or ureteral orifice junction, nasal passages, etc., such foreign articles 50 including vena cava filters, parts of medical devices, such as catheters, guidewires, cardiac leads, etc., which may break and become detached during medical procedures. Most of such instruments employ a flexible catheter formed as a tubular sheath adapted to penetrate body passages to reach the location from where the object is to be evacuated, typically employing flexible wires to snare or capture targeted objects.
Incorporated by reference in their entireties are the following for details as to the dimensions and materials that may be employed for certain elements and aspects of the present described embodiments: U.S. Pat. Nos. 5,658,296; 6,168,603; and 6,491,698 to Bates et al.; U.S. Pat. Nos. 5,300,086 to Gory et al.; U.S. Pat. No. 5,944,728 to Bates; U.S. Pat. No. 6,331,183 to Suon; and U.S. Pat. No. 6,506,209 to Teruo; U.S. Pat. No. 6,679,893 to Tran; U.S. Pat. No 8,469,970 to Diamant; 20140276920 to Hendrick; 20140155908 to Rosenbluth; 20130317516 to Teague; 20140121672 to Folk; and 20100204711 to Kear. In certain embodiments of the present invention the movable jaws are operable via the trigger on the handle end of the device, with such jaws being preferably constructed to collapse and retract inside the sheath. In the protracted position, the jaws are open so as to grasp the object. Removal of the catheter, which comprises the central portion with its corrugated flexible extent, enables the whole device to be removed from the body organ together with the object immobilized within the jaws. In certain embodiments, the reversibly movable opposing grasping structures 11, e.g., jaws, fingers, nets (15, 16), etc. are guided through the body to the site of a kidney stone and is used to grasp and remove the stone under the guidance of an endoscope.
Preferably the jaws comprise spring-like fingers 11 with sufficient rigidity to reliably hold a foreign body 50. In other embodiments, the distal end of the device comprises a pair of nets 15, 16 that are movable between open and closed positions such that a foreign body can be entrapped within the nets upon movement of the trigger to move the nets into the closed position. One will appreciate that the surgical device described herein is essentially a mere smaller version of the larger device described herein that is able to grasp larger objects.
As illustrated in
In yet further embodiments of the present invention, various other features can be included, one or more selected from the list of the following (detailed support for how such features can be implemented will be clear to one of skill in the art as guided by the present application, as well as the patent references incorporated herein: magnets (positioned on the distal end of the device); supplanting or adding sharp cutting implements 52 to one or both of the jaws such that a severing operation can be performed. The sharpened cutting jaws 52 can be alternatively be operated by a separate handle trigger—or simply provided in a fashion such that the cutting blade can be reversibly retracted by a user (either remotely via a handle trigger operation—or manually, prior to the extension of the device.) Similarly, suction cups can be positioned and affixed to the distal end of the device, whether on the jaws themselves or associated surfaces of the distal end, such that additional securement of remote objects is facilitated. Given the flexible nature of the device, it is possible to twist two separate extensions around each other, thus forming a single extension that comprises a twisted (helical) portion of a device, which can have two separate triggers to operate the pulling of cords extending in the separate extended, twisted portions. This facilitates further options for a user in certain situations where an additional set of operable distal features, such as a separate set of jaws, may be useful. A lighting source can also be positioned at the distal end of the device so that a user can more readily see the distal end and facilitate proper positioning of the distal end to perform operations, such as clamping of jaws around a distant object that may be in a darkened environment. LED lighting sources with small, battery powered energy sources are preferred, but one of skill in the art will appreciate, given the guidance provided herein, the vast variety of other lighting arrangements and features that can be employed while still being within the scope of the claimed invention. A magnifying viewing device (e.g., a distally positioned camera) can also be provided to assist the user in viewing the distal end of the device in particular applications, such as when a detailed and sensitive manipulation of a remote object is required and the user requires magnification of the distal end to properly position the device to perform desired functions.
Various embodiments are directed to a selectively bendable remote gripping tool for entrapping an object located in a body for its extraction therefrom, the tool comprising a jaw portion having a pair of net assemblies movable relative to each other between fully clamped and fully opened positions thereof; a handle portion spaced apart from the jaw portion by a selectively extendible central portion, the handle portion comprising a first manually-actuatable trigger operatively connected to the jaw portion by a selectively extendible pull member at least substantially disposed within the central portion. Actuation of the trigger is operative to move the pull member to thereby selectively position the pair of net assemblies between the fully clamped and fully opened positions. The central portion preferably comprises at least two separate portions that include hollow, corrugated members that have alternating ridges and grooves, with the central portion being bendable so as to position the tool into a desired bent configuration. A pull member comprising at least one cord operatively connects the handle portion to the jaw portion, with the at least one cord extending through the central portion. Miniature versions of the tool are adapted and configured for withdrawing thromboembolic material and other foreign objects from body lumens and cavities, employing a pair of jaws, nets, or a combination thereof. Thus, in certain embodiments the invention is directed to a method and apparatus for managing polyps by which an elongated corrugated flexible member is positionable within a working channel of an endoscopic device, with a selectively bendable central column that at its distal end has opposing nets that are movable between open and closed positions via a handle having a trigger that operates the nets, thus allowing a physician to, for example, grasp an object, such as portion of a foreign body, a polyp, a clot, a stone, etc. in a fashion that retains the object for removal with the corrugated flexible member.
