The present invention relates to a reusable device, and more particularly, this invention relates to a reusable device having one or more cutting surfaces for making straight cuts of a material.
Plastic is commonly used by painters, e.g., for masking and/or covering items to protect them from coming into contact with wet paint. However, the plastic used by painters (also referred to herein as painter's plastic) is sold in large quantities (e.g., rolls) that are housed in boxes that frequently fall apart before the entirety of the large quantity of plastic can be used. The majority of boxes in which the painter's plastic is sold are made from cardboard or similar materials. Thus, exposure to liquids (e.g., rain, puddles, paint, etc.) can cause deterioration of the box. As a result, the painter's plastic is exposed and as a result becomes unraveled and/or damaged.
Moreover, because painter's plastic is sold in large quantities, pieces of different sizes are cut off the roll to fulfil a particular use. For example, a 10 foot long piece of painter's plastic may be cut off the roll to cover an object having a length of 8 feet, while a 5 foot long piece of painter's plastic may be cut off the roll to cover an object having a length of 2 feet.
Further still, the painter's plastic is folded over on itself multiple times. Thus cuts made to the painter's plastic that are not straight, e.g., crooked, jagged, etc., are amplified when the folded material is unfolded. This is particularly undesirable when using the painter's plastic for masking.
Conventional boxes housing the material serve as poor cutting surfaces. After only a few cuts using a surface of a conventional box as a cutting surface, the box becomes structurally degraded. As a result, the rate of deterioration for the box is increased and the box quickly becomes an unviable cutting surface as well. It is nearly impossible to achieve straight cuts in painter's plastic using conventional products.
In sharp contrast, various embodiments described herein include a device that has a durable cutting surface for making straight cuts in a material. Furthermore, different devices describe below desirably introduce a reusable housing for the material that may also serve as a carrying case, as will be described in further detail below.
A device according to one embodiment includes a sidewall defining an interior; at least one cutting channel having, and/or configured to receive, at least one cutting strip; an opening in the sidewall configured to allow a sheet of material to pass therethrough from the interior; a door coupled to the sidewall; and a handle coupled to the sidewall.
A device according to another embodiment includes a peripheral sidewall; a lid coupled to an upper edge of the peripheral sidewall, the lid and the peripheral sidewall defining an interior; a bottom edge of the peripheral sidewall defining an opening to the interior, the interior being configured to receive a sheet of material; at least one cutting channel having, and/or configured to receive, at least one cutting strip; and an opening in the lid, the opening being configured to allow the sheet of material to pass therethrough from the interior.
Other aspects and advantages of the present invention will become apparent from the following detailed description, which, when taken in conjunction with the drawings, illustrate by way of example the principles of the invention.
For a fuller understanding of the nature and advantages of the present invention, as well as the preferred mode of use, reference should be made to the following detailed description read in conjunction with the accompanying drawings.
The following description is made for the purpose of illustrating the general principles of the present invention and is not meant to limit the inventive concepts claimed herein. Further, particular features described herein can be used in combination with other described features in each of the various possible combinations and permutations.
Unless otherwise specifically defined herein, all terms are to be given their broadest possible interpretation including meanings implied from the specification as well as meanings understood by those skilled in the art and/or as defined in dictionaries, treatises, etc.
It must also be noted that, as used in the specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless otherwise specified. It should also be noted that, as used herein, the term “about” with reference to some stated value refers to the stated value ±50% of said value. Further, while illustrative values are presented throughout, this is done by way of example only and without limitation. Accordingly, any modification, alteration, or equivalent of the various embodiments described herein, as would be appreciated by one having ordinary skill in the art upon reading the descriptions, should also be considered within the scope of this disclosure.
As mentioned above, painter's plastic is conventionally sold in large quantities (e.g., rolls) that are housed in boxes that frequently fall apart before the entirety of the large quantity of plastic can be used. The majority of boxes in which the painter's plastic is sold are made from cardboard or similar materials. Thus, exposure to liquids (e.g., rain, puddles, paint, etc.) can cause deterioration of the box. As a result, the painter's plastic is exposed and as a result becomes unraveled and/or damaged.
Furthermore, these conventional boxes housing the material serve as poor cutting surfaces. After only a few cuts using a surface of a conventional box as a cutting surface, the box becomes structurally degraded. As a result, the rate of deterioration for the box is increased and the box quickly becomes an unviable cutting surface in addition to an unsuitable housing for the roll of material therein.
In sharp contrast, the following description discloses several preferred embodiments of a reusable device and/or related systems and methods. As previously mentioned, the reusable device preferably has at least the ability to make significantly straight cuts of a material via cutting surfaces. Moreover, other embodiments herein may further incorporate additional features including, but not limited to, replaceable sacrificial cutting surfaces and/or handles for carrying the device, as will soon become apparent.
Looking to
Referring specifically to
Preferably the main body 101 is constructed of a substance strong enough to withstand external forces exerted on the device 100 when cutting a material as will soon become apparent. Moreover, it is desirable that the main body 101 is constructed of a substance capable of protecting material (e.g., painter's plastic) housed therein from external contaminants. Illustrative substances for the main body 101 and/or any other part of device 100 may include plastic, nylon, wood, metal, rubber, etc., or any other substance which would be apparent to one skilled in the art upon reading the present description.
According to different embodiments, the main body 101 may be formed using different processes. For example, if the main body of the device is made using metal, the main body may be constructed using bending, stamping, bar breaking, spot welding, etc. According to another example, if the main body of the device is made using wood, the main body may be constructed using screws, adhesives, fasteners, etc.
The door 106 is coupled to the main body 101 and opens allowing access to an interior area 107 defined by a main body 101. In other words, the inside surface of the main body 101 of the device 100 defines the interior 107. In preferred approaches, the door 106 may be coupled to the main body 101 of the device 100 via one or more hinges 102 of a type known in the art. Thus, the door 106 may be swung between open and closed positions as seen in
Looking now to
However, in some instances, a product being inserted into the interior 107 may be dimensionally smaller than the spatial dimensions of the interior 107 itself, e.g., may have a shorter length that that of the interior 107. In other words, although the product may be fully inserted into the interior area 107, once the door 106 is closed, the product may not be long enough to come into contact with opposite ends of the device 100. This is undesirable as when the device 100 is transported and/or used, the product may shift in the interior area 107 of the main body 101 of the device 100, thereby making it difficult for a user to access a roll of material held in the product. Therefore, spacers may be implemented in some embodiments.
The interior area 107 of the main body 101 of the device 100 may be configured to receive a spacer. A spacer (not shown) may be positioned on one or both ends of the interior area 107 of the main body 101 of the device 100, thereby effectively shortening the length of the interior 107. As a result, although a product being inserted may be dimensionally smaller than the interior 107, the spacers reduce the spatial dimensions of the interior area 107 and provide a more desirable fit for the product. Moreover, the spacers preferably center the product along the length of the device, e.g., such that a sheet of material protruding from the product is about aligned with at the opening 114.
In further approaches, the spacers may be reversible. According to the present description, “reversible” is intended to mean that the one or more spacers may be positioned in the interior area 107 with a first orientation that results in effectively shortening the length of the area as described immediately above. However, the spacers may be positioned in a second orientation that is shifted from the first orientation about 180°. When in a second orientation, an open end of the spacer may receive an end of a product having larger dimensions than a product which may be received by the interior 107 having the spacers be positioned in the first orientation. Thus, the spacers may fit over the ends of a product having larger spatial dimensions when in a second orientation during normal use, and the spacers may also be flipped to a first orientation when receiving a product having smaller dimensions (e.g., length) than a length of the interior 107.
Furthermore,
According to the in use embodiment illustrated in
Referring still to
Although it is not readily apparent when looking at the different views of device 100 in
In to various embodiments the latch 112 and a buckle may include any coupleable pair of objects. In one example, the latch 112 may include a loop of string permanently attached to the door 106, while the buckle includes a hook permanently attached to the main body 101 for receiving the loop of string. In another example, the latch 112 may include a piece of flexible material having one end permanently attached to the door 106 and a free end attached to one piece of a snap fastener, while the buckle includes the second piece of a snap fastener that is permanently attached to the main body 101.
Referring momentarily to
According to alternative embodiments, one or more slots may be incorporated in the side of the main body 101, e.g., to function as a handle. Depending on the desired embodiment, one slot large enough to receive a user's hand, several slots large enough to receive a user's fingers, etc. may be added on any one or more of the surfaces of the main body 101.
Opening 114 extending through a surface of the main body 101 is preferably large enough (dimensionally) to allow for a sheet of material to pass therethrough from the interior 107. It follows that the shape and size of the opening 114 may vary depending on the desired embodiment. Moreover, the edges of the main body 101 forming the opening 114 are preferably patterned such that they form a non-abrasive edge which prevents causing damage to a material when being pulled through the opening 114 from the interior area 107. Depending on the substance of the main body 101, the edges of the main body 101 forming the opening 114 may be sanded, bent, rounded, etc. to form a non-abrasive edge. Again, the exemplary embodiment in FIGS. 1A-1F of U.S. Provisional Patent Application No. 61/971,423, which has been incorporated by reference, illustrates a process of inserting a product into the device and cutting a desired amount of material extracted from the product using cutting surfaces formed by cutting strips positioned in the cutting channels.
Cutting strips 118 are positioned in the cutting channels 110, thereby forming cutting surfaces on portions of the cutting strips 118 that are exposed in the cutting channels 110. In some approaches, the cutting strips 118 may be permanently positioned in the channels 110, e.g., using adhesive(s), fasteners, etc. However in other approaches, the cutting strips 118 may slide into the channels such that they may be replaced after a certain amount of use. Thus in some embodiments, the channels 110 are able to receive removable cutting strips 118 that may therefore be replaced when desired. As illustrated, according to one approach the channels 110 may use a replaceable rail system that allow for the cutting strips 118 to be slid in or out of the channels 110 when desired.
The cross-sectional profiles of the channels 110 may vary to fit cutting strips 118 of different sizes and/or shapes, depending on the desired embodiment. According to exemplary embodiments, the channels 110 may have a cross-sectional profile that fits a standard paint mixing stick serving as a cutting strip 118. Such embodiments may be advantageous as paint mixing sticks are cheap and readily available, thereby resulting in minimum upkeep costs of the cutting device during use.
In other embodiments, the cutting strips 118 may include a sacrificial material which may include, but is in no way limited to, Teflon, plastic, nylon, wood, metals (e.g., cold-rolled steel), etc., or any other material which would be apparent to one skilled in the art for making a cutting surface upon reading the present description. According to some embodiments, the substance used to form the cutting strips 118 may determine whether they are stationary or replaceable as described above.
As mentioned above, a product having a roll of material may be received (e.g., inserted into) the interior 107 of the device 100. Moreover, a sheet of material may be pulled from the interior 107 and through the opening 114. Once a desired length of the sheet of material has been pulled through the opening 114, the material may be stretched flat over one of the channels 110, whereby the corresponding cutting surface may be used to cut the material using an external cutting device, e.g., any object having a sharp edge suitable for cutting.
As described above, the material (e.g., painter's plastic) may be folded over on itself multiple times in some embodiment. The act of cutting sheets of materials which have been folded over upon themselves multiple times quickly dulls the cutting edge (sharpness) of the cutting device used to cut the material. As a result, it may be undesirable for some of the devices described herein to incorporate an integrated cutting device. Accordingly, device 100 may not include an external cutting device, thereby omitting the use of cutting tools that are integrated with device 100. In other words, device 100 may include the proviso that no one or more integrated cutting devices are coupled to the device 100. If integrated cutting tools were implemented, they would become stuck and bind due to the multiple layers of material being cut through. Furthermore, cutting certain types of material can quickly dull a blade, which would render an integrated cutting device, and ultimately the device as a whole, useless.
Rather, as previously mentioned, an external cutting device is preferably used to cut the material at the cutting surface. As would be appreciated by one skilled in the art, the cutting edge of the external cutting device may be pressed against the cutting surface and run along the length of the channel 110, thereby forming a separation (cut) between two portions of the material. The channel 110 desirably guides the external cutting device, thereby producing a substantially straight cut of the material. As a result, the cut section of material may desirably have straight edges. Straight edges are particularly desired when using the cut section of material for masking as any jagged edges are amplified when the folded material is unfolded.
Referring again to
It follows that, without such recessed portions 108 of the door 106, if the external cutting device were to be drug to the end of the cutting strip 118, the external cutting device would come into contact with the door 106 when closed and positioned flush against the end of the device (as described above), thereby causing damage to the door 106, external cutting device and/or user, e.g., depending on the material of the door, type of external cutting device being used, etc.
Furthermore, the recessed portions 108 of the door 106 are also preferably shaped to retain the cutting strips 118 when the door is secured in a closed position. Looking to
Additional embodiments may further include a retractable hanger. The retractable hanger may be extended, folded, etc., to a hanging position to hang the device from a ledge, hook, hole, pole, etc. off the ground. This desirably allows for the device to be supported off the ground, thereby allowing for easier access to a user, prevention of damage and contamination to the device and/or the material stored therein, etc.
The retractable hanger is preferably positioned towards the side of the device having the slot, e.g., the top, such that while the device is hanging from the hanger, the material may still be accessed and/or cut along the cutting surfaces.
Additionally or alternatively, a retractable hanger 302 may function as a fold-out leg 302 to stabilize and/or angle the device when on the ground (e.g., see
In yet further approaches, fold-out legs may additionally or alternatively support the device such that a bottom surface of the device is suspended above the ground, e.g., to prevent damage and contamination to the device and/or the material stored therein. Illustrative embodiments of devices 300, 350 having fold-out legs 302 coupled thereto using pivotable joints 304 are shown in
Although
The device 200 further includes channels 110 for receiving cutting strips (not shown) and leg 202 coupled to the rotational axis 204 of the device. Alternatively, as illustrated in
Referring again to
Furthermore, due to the circular profile of the devices 200, 250, the main bodies 208, 252 may be rotated about the rotational axis 204 to achieve a desired orientation of the channels 110 and accordingly, the cutting surfaces. Moreover, once the device is positioned in a desired orientation, locking mechanisms (not shown) may be engaged to prevent further rotation of the main body, e.g., while pulling and/or cutting the material from a corresponding product stored in an interior of the main body. It follows that upon cutting a portion of the material, the locking mechanisms may be disengaged, thereby allowing the main body of the device to rotation about rotational axis 204 again.
In some embodiments, a device may simply be a cap piece that is placed over the top of a product, e.g., containing and/or being a sheet of material to be cut. According to an approach, as shown in
Referring still to the present exemplary cap piece device, with the bottom surface removed, a bottom edge of the peripheral sidewall may define an opening of a recessed portion which exposes the interior of the device. Accordingly, the interior (e.g., see interior 107 above) of the device may be configured to receive a product (e.g., sheet of material) by placing the device over the top of the product as mentioned above. Thus a cap piece device may provide a desirable cutting surface for making straight cuts in the material.
According to different approaches, a cap piece device may include any of the features of any of the embodiments described above, e.g., channels, cutting strips, recessed portions, a slot, etc., or any other feature which would be apparent to one skilled in the art upon reading the present description.
A cap piece may be particularly useful in embodiments having large products, e.g., large containers, rolls and/or sheets of material, boxes, etc. Thus, rather than manufacturing, shipping, storing, etc., devices having interior areas inside the main body of the device large enough to receive said particularly large products, a cap piece device may simply be placed over the top of the particularly large products, providing similar and/or the same functionality as any of the other embodiments described herein.
Each of the steps of the method 400 may be performed by any suitable component of the operating environment. For example, in various embodiments, the method 400 may be partially or entirely performed by a controller, a processor, etc., or some other device having one or more processors therein. The processor, e.g., processing circuit(s), chip(s), and/or module(s) implemented in hardware and/or software, and preferably having at least one hardware component may be utilized in any device to perform one or more steps of the method 400. Illustrative processors include, but are not limited to, a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), etc., combinations thereof, or any other suitable computing device known in the art.
As shown in
As cutting strips are used over time, their sacrificial nature may cause the cutting strips to become weathered thereby resulting in a sub-optimal cutting surface. Accordingly, it may be desirable to remove and replace the used cutting strips after a predetermined amount of time, number of cuts, user discretion, etc., depending on the desired embodiment.
Referring still to
Method 400 additionally includes extracting a sheet of material through an opening of the device from the roll of material positioned in the interior of the device. See operation 414. Furthermore, operation 416 includes stretching the sheet of material over a cutting surface formed by the cutting strip of the cutting channel. Thereafter, the material may be cut along the cutting surface with an external cutting device. See operation 418. Again, the exemplary embodiment in FIGS. 1A-1F of U.S. Provisional Patent Application No. 61/971,423, which is incorporated by reference, illustrates a process of inserting a product into the device and cutting a desired amount of material extracted from the product using cutting surfaces formed by cutting strips positioned in the cutting channels, any aspect of which may be implemented in conjunction with any one or more of the operations of method 400 above.
It should also be noted that for any of the embodiments described herein, a roll of material may be removed from its corresponding box before being inserted into a device. Moreover, some devices, e.g., those devices having circular or rounded side profiles, may be designed and/or constructed for receiving only a roll of material.
Additional exemplary embodiments are also presented below. Looking to the supplementary images attached, any of the corresponding features depicted therein may be implemented in conjunction with features from any other embodiment listed herein, such as those described with reference to the other FIGS. Of course, however, such attached supplementary images may be used in various applications and/or in permutations which may or may not be specifically described in the illustrative embodiments listed herein. Further, the attached supplementary images presented below may be used in any desired environment. Thus the attached supplementary images (and the other FIGS.) should be deemed to include any and all possible permutations.
The inventive concepts disclosed herein have been presented by way of example to illustrate the myriad features thereof in a plurality of illustrative scenarios, embodiments, and/or implementations. It should be appreciated that the concepts generally disclosed are to be considered as modular, and may be implemented in any combination, permutation, or synthesis thereof. In addition, any modification, alteration, or equivalent of the presently disclosed features, functions, and concepts that would be appreciated by a person having ordinary skill in the art upon reading the instant descriptions should also be considered within the scope of this disclosure.
While various embodiments have been described above, it should be understood that they have been presented by way of example only, and not limitation. Thus, the breadth and scope of an embodiment of the present invention should not be limited by any of the above-described exemplary embodiments, but should be defined only in accordance with the following claims and their equivalents.
The present application claims benefit of U.S. Provisional Patent Application No. 61/971,423 filed Mar. 27, 2014, which is incorporated by reference.
