DETAILED DESCRIPTION

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the various described embodiments. However, the described embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.


Embodiments relate to a footwear removal device that includes two bases and a bridge connecting that two bases. Each of the bases has a front grip and a rear grip for catching the toe cap and the heel of the footwear, respectively. The bridge coupled to the two bases in a rotatable manner or a removable manner so that the bases and the footwear removable device can be folded or disassembled for carrying or storing. Each of the bases may be a single solid piece or comprise two parts that can be disassembled/assembled to change the overall length of the base. Embodiments provide a simple, inexpensive footwear removal device with a small number of components and are easy to assemble and carry.



FIG. 1 is a perspective view of a footwear removal device 5 in an expanded state, according to one embodiment. The footwear removal device 5 may include, among other components, two bases 10L, 10R and a bridge 14 connecting the two bases 10L, 10R. Base 10L is used for removing the left footwear while base 10R is used for removing the right footwear. The footwear removal device 5 may be placed on a floor before use.


Each of the bases 10L, 10R (collectively referred to as “bases 22” or individually also as “base 22”) includes a front grip 22L, 22R (collectively referred to as “front grips 22” or individually also as “front grip 22”) and a rear grip 26L, 26R (collectively referred to as “rear grips 26” or individually also as “rear grip 26”). The front grip 22 and the rear grip 26 are placed at the front and the rear of the base 10, respectively. In one or more embodiments, the entire base is made of the same material, and can be formed, for example, by a manufacturing process such as injection molding. The front grip 22, the rear grip 26 and the remaining bottom body of the base 10 may be integrated into a single body without removable parts. The bases 10 can be made of, for example, plastic such as High-Density Polyethylene (HDPE).


In one or more embodiments, the front grip 22 is longer than the rear grip 26. The front grip 22 is dimensioned and oriented to catch the front portion (e.g., toe cap) of the footwear between the front grip 22 and the bottom portion of the base 10. The rear grip 26 is dimensioned and oriented to catch the rear portion (e.g., heel) of the footwear. The rear grip 26 may have an edge 28 (also referred to as edges 28L, 28R herein) facing towards the front grip 22. The edge 28 is concaved to match the general shape of a footwear's heel so that the pressure is spread evenly across the footwear's rear portion when the user attempts to remove the footwear.


The bridge 14 is a member that connects the two bases 10. The bridge 14 may be made of the same material as the bases 10. The bridge 14 may be a long rectangular shape, and may be coupled between the bases 10 using, for example, screws 18L, 18R (collectively referred to as “screws 18” or individually also as “screw 18”). The bridge 14 has holes 32 at both ends for receiving the screws. The bases 10 may also have holes 34 at the center to receive the screws 18. The screws 18 may be tightened so that the bases 10 and the bridge 14 are firmly fixed. The screws 18 may be loosened or removed to fold the footwear removal device 5 (for example, as shown in FIG. 4) or to disassemble the footwear removal device. Instead of screws, non-removable fixing components such as hinges may be used to secure the bridge 14 and the bases 10. The bridge 14 can be made of, for example, High Density Polyethylene (HDPE).


Although the bridge 14 is illustrated in FIG. 1 as being coupled to center longitudinal locations of the bases 10, the bridge 14 may be coupled to different locations of the bases 10 (e.g., rear or front parts of the bases 10). Moreover, two or more bridges may be used to connect the bases 10.



FIG. 2A is a cross-sectional view of the footwear removal device 5 of FIG. 1, taken along line A-A′, according to one embodiment. The bridge 14 is placed below the bottom surface of the base 10 and is connected by the screw 18. For this purpose, the base 10 and the bridge 14 are formed with hole 34 and hole 32, respectively. In the example of FIG. 2A, the thickness T1 of the base 10 is generally the same as the thickness T2 of the bridge 14.



FIG. 2B is s a cross-sectional view of the footwear removal device 5 of FIG. 1, taken along line A-A′, according to another embodiment. In the embodiment of FIG. 2B, the base 10 is formed with an indent 36 at its bottom surface so that the bridge 14 can be placed in the indent 36. The bridge 14 also has a thickness T3 that is thinner than the thickness T1 of the base 10. Hence, when the bridge 14 is placed in the indent 36, the bridge 14 does not protrude from the bottom of the base 10 or protrudes to a lesser extent compared to the embodiment of FIG. 2A.


In other embodiments, the bridge 14 may be placed on the top surface of the base 10 rather than beneath the bottom surface of the base 10.



FIGS. 3A through 3C illustrate a process of removing a footwear 54 using the footwear removal device 5 of FIG. 1, according to one embodiment. First, the user inserts the toe cap of the footwear 54 into space between the front grip 22 and the bottom portion of the base 10, by pushing the footwear 54 in a direction indicated by arrow B, as shown in FIG. 3A. During this time, the other footwear or foot of the user may press the other base to prevent moving of the footwear removal device 5. After placing the toe portion beneath the front grip 22, the heel of the footwear 54 is pressed down under the rear grip 26 by moving the heel in a direction indicated by arrow C, as shown in FIG. 3B. Then, the user may remove his or her foot 58 from the footwear 54, by pulling up the foot 58 as shown in FIG. 3C, with the footwear 54 held in place by the front grip 22 and the rear grip 26. To prevent the footwear removing device 5 from moving along with the foot 58, the other base may be pressed down by the other footwear or the foot.



FIG. 4 is a perspective view of the footwear removal device 5 in a folded state, according to one embodiment. After use, the footwear removal device 5 may be folded to save the space for storing or carrying the footwear removal device. To fold the footwear removal device 5, the bridge 14 may be rotated relative to the bases 10 so that the bases come closer or abut each other.



FIG. 5 is a perspective view of an adjustable base 100 in a footwear removal device, according to another embodiment. Only one of the base 100 is described with reference to FIG. 5, but the footwear removal device 5 may include another base with a symmetric structure and connected via bridge through a screw 18. To enable adjustment of the length L of the base 100, the base 100 may be formed of two pieces 62, 68 that can be displaced in a longitudinal direction of the base 100.


The piece 62 includes the rear grip 26 while the piece 68 includes the front grip 22. In the example of FIG. 5, the pieces 62, 68 have teethed portions that can be adjusted from a shortened state (as shown in FIG. 6) where the length of the base 100 is L1, to an extended state (as shown in FIG. 7) where the length of the base 100 is L2. The pieces 62, 68 can be assembled with different teeth portions engaging each other so that the overall length of the base 100 is adjusted. By adjusting the length of the base 100, the footwear removal device may be used to remove footwears of different sizes.


Although only one extended state is illustrated in FIG. 7, the base 100 can be placed in various extended states with different lengths by adjusting the relative location of the pieces 62, 68 and then locking the teeth of the pieces 62, 68. For this purpose, the pieces 62, 68 may be separated by making vertical relative movement of the pieces 62, 68, moving the pieces 62, 68 longitudinally, and then engaging the teeth of the pieces 62, 68.


Various other structures can be used to enable adjustment of the length of the base 100. Further, other structures such as clamps or screws may be used to lock the pieces of the base 100 once the length of the base 100 is adjusted.
