Detailed reference will now be made to a first potential embodiment of the disclosure, which is illustrated in FIGS. 1 through 5.
The shoe removal assist device 100 (hereinafter invention) comprises a shoe grip 101, a shaft 102, and a handle 103. The invention 100 is a device that is adapted for use with shoes 141. The invention 100 is a lever-operated device that grips the heel 144 of a shoe 141 with a plurality of spikes 113. The plurality of spikes 113 grips the shoe 141 such that the invention 100 holds the shoe in 141 position and allows the wearer to remove their shoe 141 from the foot 142. The invention 100 is configured such that it can be operated from a standing position.
The shoe grip 101 further comprises a base 111, a heel wall 112, the plurality of spikes 113, a plurality of spike holes 114, a spike plate 115, a linkage housing 116, and a spike plate wedge 117. The base 111 is the foundation of the shoe grip 101. The base 111 is the plate that sits on a support surface 143 and upon which the shoe 141 is placed. As shown in FIG. 5, the base 111 is further defined with a curved end 118. The horizontal surface 119 of the base 111 defines the location where the shoe 141 will be placed. The heel 144 of the shoe 141 is placed against the heel wall 112. The heel wall 112 projects perpendicularly away from the horizontal surface 119 of the base 111 around the curved end 118. The heel wall 112 has formed in it the plurality of spike holes 114. As shown most clearly in FIGS. 3 and 4, the plurality of spikes 113 and the spike plate 115 is contained with the heel wall 112. Each of the plurality of spikes 113 is a protrusion made from an elastomeric material that is attached to and extends from the face of the spike plate 115. Each of the plurality of spikes 113 is positioned on the spike plate 115 such that each of the plurality of spikes 113 is aligned with a hole selected from the plurality of spike holes 114.
The space contained within the heel wall 112 is connected to the space within the linkage housing 116 through an opening called the port 120. The linkage housing 116 is an apparatus that converts the vertical motion of the transfer strut 125 to horizontal motion in the spike plate 115. This linkage is provided using the spike plate wedge 117. When the transfer strut 125 moves down, the spike plate wedge 117 moves towards the heel wall 112 moving the spike plate 115 towards the heel 144 of the shoe 141. This motion of the spike plate 115 pushes the plurality of spikes 113 through the plurality of spike holes 114 bringing the plurality of spikes 113 in contact with the shoe 141. The friction of the contact between the plurality of spikes 113 and the shoe 141 holds the shoe 141 in position while the foot 142 is removed from the shoe 141. When the trigger 132 is released, the retraction of the transfer strut 125 returns the spike plate wedge 117, the spike plate 115, and the plurality of spikes 113 to each of their original positions.
The shaft 102 is a hollow tube that is used to separate the handle 103 away from the shoe grip 101. The shaft 102 further comprises a transfer strut 125. The shaft 102 further comprises a first end 151 and a second end 152. The transfer strut 125 is a cylindrical bar placed in the center of the shaft 102 such that the transfer strut 125 and the shaft 102 are aligned. The transfer strut 125 is the linkage between the operations of the shoe grip 101 to the operations of the handle 103. The transfer strut 125 is further defined with a third end 153 and a fourth end 154.
The handle 103 further comprises a fixed grip 131, a trigger 132, and a return spring 133. The handle 103 is located at the first end 151 of the shaft 102. As best shown in FIGS. 2 and 3, the fixed grip 131 is a first handhold that projects perpendicularly away from the center axis 150 of the shaft 102. The trigger 132 is a second handhold that projects perpendicularly away from the center axis 150 of the shaft 102. The trigger 132 is further defined with a fifth end 155 and a sixth end 156. The sixth end 156 of the trigger 132 is attached to the third end 153 of the transfer strut 125. The trigger 132 is attached to a pivot point 126 such that when the fifth end 155 of the trigger 132 is pulled towards the handle 103 the sixth end 156 of the trigger 132 pushes the third end 153 of the transfer strut 125 towards the shoe grip 101. The return spring 133 is a helical coil tension spring that is further defined with a seventh end 157 and an eighth end 158. The seventh end 157 of the return spring 133 is attached to the handle 103. The eighth end 158 of the return spring 133 is attached to the sixth end 156 of the trigger 132.
When the fifth end 155 of the trigger 132 is pulled towards the fixed grip 131, the sixth end 156 of the trigger 132 moves away from the fixed grip 131 towards the shoe grip 101. This movement extends the return spring 133 thereby placing the return spring 133 under tension. When the trigger 132 is released, the return spring 133 releases the tension it is under by returning to its original position which in turn returns the sixth end 156 of the trigger 132 and the third end 153 of the transfer strut 125 returns to each of their original positions.
In the first potential embodiment of the disclosure, the fixed grip 131, the trigger 132, the base 111, the heel wall 112 including the plurality of spike holes 114, spike plate 115, and the linkage housing 116 are each formed from molded plastic. Suitable plastics include, but are not limited to, high density polyethylene or acrylic poly (methyl methacrylic). Each of the plurality of spikes 113 is made from polyurethane. The return spring 133 is a commercially available spring. The shaft 102 and the transfer strut 125 are commercially available tubes. The pivot point 126 and the spike plate wedge 117 are formed from commercially available hardware.
To use the invention 100, the shoe 141 is placed on the horizontal surface 119 such that the heel 144 is proximal to the heel wall 112. The trigger 132 is pulled towards the fixed grip 131 to securely hold the shoe 141 in position. The foot 142 is then removed from the shoe 141.
The following definitions were used in this disclosure:
