Description

FIELD OF THE DISCLOSED TECHNOLOGY

The disclosed technology relates to dispending devices. More specifically, the disclosed technology relates to a sandpaper dispensing device.

BACKGROUND OF THE DISCLOSED TECHNOLOGY

Conventional dispensing devices involve many working components for cutting an item dispensed by the device. For example, U.S. Pat. No. 3,102,671 to Gershen discloses a tape dispenser including a hingedly connected tape severing arm having a cutting-edge that swings over a tape dispensing aperture to sever tape positioned through the aperture.
U.S. Pat. No. 6,092,657 to Hopkins discloses a box system for supporting and dispensing sandpaper including a rectilinear box having a slot and a serrated cutting-edge positioned exterior to the box for cutting sandpaper pulled through the slot and positioned over the serrated cutting-edge.
While these references disclose dispensing devices for supporting and dispensing items, such as tape and sandpaper, as well as means for cutting said items, improvements are needed in dispensing and cutting means that simultaneously prevent the dispensed item from retracting into the box, provide a means for acquiring the items if retracted, and provide a means for cutting the dispensed item from within the box.

SUMMARY OF THE DISCLOSED TECHNOLOGY

Disclosed herein is a sandpaper dispensing device including a body including an upper portion, a lower portion, an interior cavity, and a curvilinear wall. The interior cavity is configured to receive and sustain a roll of sandpaper therein.

The curvilinear wall 18 includes a middle region 46 extending between the first end 20 and the second end 22. The middle region 46, the first end 20, and the second end 22 are circular in shape in that they are curvilinear in nature, although the curvilinear wall 18 does not form a complete circle. The first end 20 is flexible about the middle region 46 such that the first end 20 is bendable radially inwardly toward the interior cavity 16 and interior portion 26.
The interior portion 26 is rigid and defines a curve 48 that is parallel with a curve 50 of the curvilinear wall 18 such that all points of the curve 48 of the interior portion 26 are at a fixed normal distance from the curve 50 of the curvilinear wall 18. The first end 20 of the curvilinear wall 18 comprises an edge 48 adapted to cut sandpaper from the roll of sandpaper 17 when the first end 20 is bent radially inwardly and pressed against the interior portion 26.
The curvilinear wall 18 also includes a first surface 50, a second surface 52 opposite the first surface 50, an upper edge 54, and a lower edge 56 opposite the upper edge 54. The first end 20 comprises an opening 58 extending entirely through the curvilinear wall 18 from the first surface 50 to the second surface 52. The opening 58 is circumscribed by the upper edge 54 and the lower edge 56 of the curvilinear wall 18. The opening 58 is in communication with the channel 28. The opening 58 is sized to receive a finger therethrough to enable engagement of sandpaper of the roll of sandpaper 17 disposed within the channel 28, as shown in FIG. 13.
The curvilinear wall 18 is fixed to the second perimeter edge 36 of second circular member 34. The curvilinear wall 18 extends orthogonally upwardly from the second perimeter edge 36. In embodiments, the curvilinear wall 18 is fixed to an integral with the second circular member 34.
The upper portion 12 is hingedly connected to the curvilinear wall 18 to pivot about the curvilinear wall 18 in an open position to provide access to the interior cavity 16 and a closed position to prevent egress of the roll of sandpaper 17 that is positioned with the interior cavity 16.
The body 11 comprises a latch 60 including a flange 62 on the upper portion 12 and a catch 64 on the lower portion 14. The latch 60 is configured to detachably connect the upper portion 12 to the curvilinear wall 18 to secure the upper portion 12 in the closed position. In embodiments, the upper portion 12 comprises a front end 66 and a rear end 68. The front end 66 of the upper portion 12 includes the flange 62. The curvilinear wall 18 includes a front end 70 and a rear end 72. The front end 70 of the curvilinear wall 18 includes the catch 64. The flange 62 and the catch 64 removably engage to secure the upper portion 12 in the closed position. In embodiments, the front end of 66 the upper portion 12 and the curvilinear wall 18 are hingedly connected via a hinge 74. The latch 60 is opposite the hinge 74.
Referring now to FIGS. 11-13, simultaneously, shows a perspective view of the sandpaper dispensing device in an open configuration, illustrating one manner in which sandpaper of a roll of sandpaper is guided from the interior cavity through the channel and out of the slot of the curvilinear wall of the sandpaper dispensing device according to one embodiment of the present disclosed technology. FIG. 12 shows a perspective view of the sandpaper dispensing device in a closed configuration, illustrating one manner in which sandpaper of a roll of sandpaper is guided from the interior cavity through the channel and out of the slot of the curvilinear wall of the sandpaper dispensing device according to one embodiment of the present disclosed technology. FIG. 13 shows a perspective view of the sandpaper dispensing device in use, illustrating one way the sandpaper is gripped through the curvilinear wall to tear the sandpaper according to one embodiment of the present disclosed technology. The interior cavity 16 includes a diameter and depth sized to receive a roll of sandpaper 17 flush therein and enable egress of the roll of sandpaper 17 therefrom. The interior cavity 16 also includes a size which restricts vertical movement of the roll of sandpaper 17 and enables planar rotation of the roll of sandpaper 17 about a vertical axis. The interior cavity 16 is also configured to withstand the roughness provided by the surface of the roll of sandpaper 17 without losing quality after holding at least 1000 rolls of sandpaper.
In one operation of the sandpaper dispensing device 10, to severe sandpaper of the roll of sandpaper 17, an end 76 of the roll of sandpaper is guided from the interior cavity 16 through the channel 28 and out of the slot 24 to an exterior of the body 11, such that a desired length of sandpaper is extending out of the slot 24. Once out of the slot 24, a user engages the sandpaper 78 present in the channel 28 through the opening 58 of the first end 20 of the curvilinear wall 18 and bends the first end 20 toward and against the interior portion 26. When the first end 20 is pressed against the interior portion 26 the pressure of the edge 48 on the first end 20 engages the sandpaper 78 within the channel 28 and severs the sandpaper 78.
