The present disclosure relates to a kit of parts for forming a gripping tool, and further to a gripping tool, as set forth in the claims.
Dog owners are expected to remove and dispose dog feces from the ground. This is commonly done in that a hand is placed inside a bag, the excrements are gripped with the hand covered by the bag, and finally turning the bag inside out to enwrap the excrements. However, gripping the dog or other household animal feces with the hands covered by a thin bag conveys the tactile sensation of gripping a warm, slushy pulp, which is perceived unpleasant. A comparatively unpleasant sensation may be perceived when picking up other refuse.
An abundance of aids for picking up dog feces and wrapping them inside a bag for disposal have been proposed in the art. ES 1 160 983 describes an aid which essentially constitutes a pincer. U.S. Pat. No. 10,100,475 describes a tool having two arms connected to each other by a hinge and further having scoop elements pivotably attached to their distal ends. However, most of the known aids for picking up animal feces or other refuse are comparatively bulky. A person walking a dog might not want to take a bag with her or him only to carry a pick-up tool. For one instance, EP 0 584 040 discloses a gripping tool wherein two arms are provided as a single piece and form a coil spring. The device proposed by U.S. Pat. No. 5,385,376 is provided as a set of tongs which are biased by a spring blade. Likewise, U.S. Pat. No. 6,059,333 proposes a gripping tool for picking up canine excrements which are hinged together and put under stress using a spring tending to maintain the device in an open position. A gripping tool which can be stowed flat and be placed in a pocket when not used but can be easily and fast be converted into a functional gripping tool, would hence be appreciated.
It is an objective of the present disclosure to propose a kit of parts for forming a gripping tool, and a gripping tool, of the type initially mentioned. In particular, a gripping tool shall be provided which allows picking up animal feces and other refuse while avoiding close contact with the hands, with only a thin bag placed between the hands and the refuse. In a more particular instance, the gripping tool shall enable to pick up the refuse and place it inside a bag in which it can be wrapped and disposed without making close contact to the refuse or feel the texture of the refuse. In another aspect, the disclosed device shall be provided such as to be stowed flat and be conveniently placed and carried in a pocket when not in use, while allowing to be easily converted into a functional gripping tool if required and to be likewise easily re-converted into a flat, space-saving configuration after use.
This is achieved by the subject matter described in claim 1.
Further effects and advantages of the disclosed subject matter, whether explicitly mentioned or not, will become apparent in view of the disclosure provided below.
Accordingly, disclosed is a kit of parts for forming a gripping tool. The kit of parts comprises a first arm shaped as a sheet and a second arm shaped as a sheet. Each arm is provided as a separate, individual part. Each arm has a distal gripping section and a proximal handle section, wherein the distal gripping section is provided as a frame encompassing a window. The first arm and the second arm comprise means at their proximal ends enabling the first and the second arm to be connected to each other at their proximal ends by a mobile connection so as to face each other. It may be said that the arms, when connected to each other at their proximal ends, face each other with inner faces of the arms. The arms, when connected to each other at their proximal ends, form a pair of tongs and define a gripping plane between them. At least one of the arms, in the handle section, comprises a protruding feature protruding from a plane connecting a distal edge and a proximal edge of said arm and provided on a face of the arm intended to face the other arm. Said face which is intended to face the other arm may also be referred to as the “inner face” of the arm, or of the sheet forming the arm, respectively. The protruding feature is intended to serve as an abutment for the other arm when the kit of parts is functionally assembled to form a gripping tool. The protruding feature is thus also referred to as the “abutment feature”. It is understood that, as the features enabling the mobile connection of the two arms are provided at the proximal ends of the arms, the handle section and hence the abutment feature, are provided distal of the features enabling the mobile connection and between the features enabling the mobile connection and the proximal end of the window of the gripping section.
In another point of view, the herein disclosed subject matter set forth in claim 1 may be considered as proposing a gripping tool comprising a first arm shaped as a sheet and a second arm shaped as a sheet, wherein each arm has a distal gripping section and a proximal handle section, and wherein further the distal gripping section is provided as a frame encompassing a window. The first and second arms are connected at their proximal ends by a mobile connection, facing each other with inner faces of the arms and defining a gripping plane between the arms. At least one of the arms, in the handle section, comprises an abutment feature protruding from a plane connecting a distal edge and a proximal edge of said arm, wherein the protruding feature is arranged between the first and the second arm. The abutment feature is intended to serve as an abutment for the respective other arm. Hence, a pressure applied on both arms distal from the abutment feature deforms the arms elastically and results in a gripping action of the gripping tool, wherein the distal edges of the arms approach each other. The connection between the first and second arms is in certain non-limiting embodiments provided such that the gripping tool can be disassembled into a kit of parts comprising the first and second arms, which in turn allows the two sheet-shaped arms to be stowed away individually. In other embodiments the gripping tool is adapted and configured to be converted from a functional configuration in which at least one of the arms abuts an abutment feature provided on the other arm and the assembled kit of parts forms an open gripping tool, to a flat, space-economic stow-away configuration, and vice versa. In use, the gripping sections of the gripping tool may be placed inside a bag intended to wrap the feces or other refuse to be removed from the ground with the distal edges of the arms being spaced apart from each other. The bag extends between the distal edges of the arms. By holding the gripping tool with the bag placed over the gripping sections, or the distal ends, respectively, of the arms downwards and placing the part of the bag extending between the distal ends over the refuse, the refuse is covered by the bag. In applying pressure on both arms distal from the abutment feature the arms flex over the abutment feature, and the distal ends of the arms perform the gripping action and are essentially shifted below the refuse. While performing this action, the refuse, covered by the part of the bag which initially was placed between the distal ends of the arms, is held within the windows while being wrapped inside the bag. The refuse wrapped inside the bag can subsequently be lifted from the ground by lifting the gripping tool. Finally, the part of the bag outside the arms can be flipped over the closed gripping tool with the refuse and closed, and the pressure on the arms can be released so as to remove the closed bag from the gripping tool. The closed bag can be disposed and the gripping tool can be converted into the stow-away configuration and can easily be carried, for instance, in a pocket of a piece of clothing. As noted above, due to the fact that the features enabling the mobile connection of the two arms are provided at the proximal ends of the arms, and consequently the mobile connection is provided at a proximal end of the gripping tool, the handle section and hence the abutment feature are provided distal of the mobile connection and between the mobile connection and the proximal end of the window of the gripping section.
It is noted that within the framework of the present disclosure the use of the indefinite article “a” or “an” does in no way stipulate a singularity nor does it exclude the presence of a multitude of the named member or feature. It is thus to be read in the sense of “at least one” or “one or a multitude of”.
In cases in which the mobile connection inhibits a center of rotation—for instance, if the mobile connection is provided by a hinge—it might be found useful if the at least one abutment feature of at least one of the arms is provided at maximum 50% of the distance from the center of rotation of the mobile connection to a most proximal edge of the window. This provides sufficient space on the arms distal to the abutment feature for grasping the arms in the handle section and applying pressure to flex the arms to perform the required gripping action. Moreover, there is a sufficient lever from the abutment feature to the distal edge of the arms so as to provide the required range of motion of the distal edges of the arms and enable that the gripping tool might be closed at the distal end, i.e. the distal edges of the arms at least essentially get in contact with each other, without excessive bending of the arms, which else might in turn result in plastic deformation or structural failure of the arms. In other embodiments, the at least one abutment feature of at least one of the arms is provided at maximum 30% or at maximum 25% or even at maximum 20% of the distance from the center of rotation of the mobile connection to a most proximal edge of the window.
In embodiments, the at least one abutment feature may be provided as a kink of the sheet forming the at least one arm. In other embodiments, the at least one abutment feature may be provided as a bulge protruding from the sheet forming the at least one arm. It may be provided that the bulge is off-centered with respect to a proximal-distal axis of the at least one arm. It may further, in particular in said embodiments, be provided that the arms, when connected to each other, i.e., when the gripping tool is assembled, may be shifted or swiveled sideways with respect to each other such that the bulge gets located lateral of the other arm and the gripping tool may be stowed flat. The term “sideways” shall be understood as a direction parallel to the sheet-plane of a respective arm.
In further exemplary embodiments a pin may extend generally across a proximal-distal axis of at least one arm, wherein the pin is provided distant from a face of the sheet forming the arm. It will be understood that the pin may advantageously be placed adjacent the face of the sheet forming the arm which is intended to face the other arm. The pin may for an instance be affixed to a lateral edge of the arm. The distance between the inner face of the sheet and the pin may be chosen such that the counterpart arm can be placed between the sheet and the pin.
As noted above, the arms comprise means at their proximal ends enabling the first and the second arm to be connected to each other at or proximate to their proximal ends by a mobile connection. In a first non-nonlimiting instance, a first one of the arms comprises at least one hinge pin at its proximal edge, the at least one hinge pin extending at least essentially in the sheet-plane of said first arm and at least essentially perpendicular to a proximal-distal axis of said first arm. The second one of the arms comprises at least one hinge knuckle at the proximal end of said second arm. The at least one hinge knuckle is dimensioned to receive the at least one hinge pin provided at the proximal edge of the first arm within the hinge knuckle. In particular, the opening of the at least one hinge knuckle which is intended to receive the at least one hinge pin is provided so as to receive and guide the hinge pin at least essentially perpendicular to a proximal-distal axis of said second arm. Hence, the at least one hinge pin provided at the proximal edge of the first arm and the at least one hinge knuckle provided at the proximal edge of the second arm are adapted and configured to jointly form a hinge connecting the two arms. In more particular instances, the at least one hinge knuckle forms a latch and is circumferentially open so as to be latched over the hinge pin in a radial direction of the hinge knuckle.
It may be provided that the at least one hinge knuckle and the at least one hinge pin are adapted and configured to be assembled to jointly form a hinge having a play along the axis of the hinge pin. This would allow the arms of an assembled gripping tool to be laterally displaced with respect to each other. This may be found useful to place one arm lateral of an abutment feature on the other arm in a stow-away configuration of the assembled gripping tool and for moving one arm abutting said abutment feature for forming a functional gripping tool.
In yet further non-nonlimiting exemplary embodiments the at least one hinge pin may be provided with a free end so as to be received in the hinge knuckle in a direction along the axis of the at least one hinge pin.
It is understood that the hinges as described above enable a relative pivoting movement of the arms relative to each other around an axis which is coplanar with the sheets forming the arms. In other embodiments, a pin extends from a first one of the arms in a proximal region of the handle section at least essentially perpendicular to the sheet plane of said first arm and a second one of the arms is formed with a through opening formed through said sheet-shaped second arm, wherein said opening is sized and shaped to receive an axle of the pin. The pin and the opening are thus adapted and configured to jointly form a hinge connecting the two arms.
In order to further enhance the space-saving stowing of the herein disclosed subject matter at least one of the arms may be collapsible. Collapsible, as herein used, may refer to any capability of reducing the size or a dimension of an arm. For one instance, at least one of the arms may be provided as a telescopic arm, wherein a distal section is extendable from a proximal section. The distal section and the proximal section may be slidably linked to each other. For an instance, the frame which is intended to encompass the window may be extendable from the handle section by a sliding movement. For another instance, at least one of the arms may be provided as a foldable arm, wherein a distal section is retractable from a proximal section. The distal section and the proximal section may be pivotably and/or hingedly linked to each other. For an instance, the frame which is intended to encompass the window may be retractable from the handle section.
In a further aspect, a gripping tool, which is particularly suited for picking up feces and other refuse is disclosed. The skilled person will appreciate that, more specifically, by virtue of disclosing the kit of parts as outlined above, also a gripping tool which is intended to be assembled from said kit of parts is disclosed.
Hence, further disclosed is, in another aspect, a gripping tool comprising two arms shaped as sheets, wherein each arm has a distal gripping section and a proximal handle section, wherein each distal gripping sections is provided as a frame encompassing a window, and wherein the arms are connected to each other at their proximal ends by a mobile connection and, in more particular embodiments, by a pivotable connection. The sheet-shaped arms face each other with inner faces of the arms. In an aspect, the arms define a gripping plane between the arms. At least one of the arms, in the handle section, comprises a protruding feature protruding from a plane connecting a distal edge and a proximal edge of said arm and provided on the inner face and facing the other arm. In more particular embodiments, the gripping tool is assembled from a kit of parts as disclosed above.
It is understood that the features and embodiments disclosed above may be combined with each other. It will further be appreciated that further embodiments are conceivable within the scope of the present disclosure and the claimed subject matter which are obvious and apparent to the skilled person.
The subject matter of the present disclosure is now to be explained in more detail by means of selected exemplary embodiments shown in the accompanying drawings. The figures show:
It is understood that the drawings are schematic, and details not required for instruction purposes may have been omitted for the ease of understanding and depiction.

When not in use, arm 21 may, due to the above-described play of the connecting hinge along the axis of hinge pins 28 and 29, and be laterally displaced relative to arm 11, as shown in
A second exemplary embodiment is shown in
In a further exemplary embodiment shown in
In the embodiment outlined in
It may in embodiments not explicitly shown, but, by virtue of the present description, being apparent to a person having skill in the art, be provided that axle 31 is dimensioned such that the proximal part of handle section 22 of arm 21 is received between the proximal part of handle section 12 of arm 11 and pin head 32 with no or minimal play. Bulge 26 is omitted in said embodiment. Arm 21 may then be placed between the handle section of arm 11 and transverse pin 35 in the stow-away configuration, while being placed above transverse pin 35 in the functional configuration, whereby transverse pin 35 serves as the abutment protrusion which enables the gripping action.
In certain embodiments, axle 31 may comprise a cam 33, while the through opening of arm 11, through which axle 31 is received, comprises a lateral recess 34 which is sized to allow cam 33 to pass through, as shown in
The additional features outlined in connection with the embodiments shown in
In the embodiments shown in
It will be appreciated that the herein disclosed subject matter provides for an inexpensive and reusable tool for gripping, picking up and disposing animal feces and other refuse. The device can be easily converted between a functional configuration and a space-saving flat and/or collapsed stow-away configuration. Said conversion can be easily effected by hand and without the use of tools. In the stow-away configuration, the gripping tool can be transported for instance in a pocket of a piece of clothing, which facilitates taking the gripping tool when for instance walking a dog.
The gripping tool can be made, for instance, from metal, recycled plastic, biodegradable plastic or bio-sourced plastic, or any other suitable material, like, while not limited to, thermoplastics. By using the gripping tool in connection with a bag, like, for instance, commonly available bags for disposing animal feces, animal feces and other refuse can be picked up, wrapped and disposed while avoiding the unpleasant tactile sensation of touching the refuse through the bag. Further, the tool will not be in direct contact with the refuse and thus stay clean. The kit of parts, and the gripping tool, are in specific embodiments sized to fit inside a commonly available bag for disposing dog feces.
While the subject matter of the disclosure has been explained by means of exemplary embodiments, it is understood that these are in no way intended to limit the scope of the claimed invention. It will be appreciated that the claims cover embodiments not explicitly shown or disclosed herein, and embodiments deviating from those disclosed in the exemplary modes of carrying out the teaching of the present disclosure will still be covered by the claims.
