Compression stocking donning aid

Abstract

Embodiments of the Compression Stocking Donning Aid are comprised of a handle assembly, a bracket assembly, and a sock applicator assembly. The handle assembly is comprised of two, mirror image handles that are covered by handle grips. The handles are essentially linear elongated cylinders that allow the user of the Aid to grasp the Aid and apply the necessary leverage to open the compression stocking for application. The sock applicator assembly is comprised of two sock applicators. The bracket assembly is comprised of a back plate, a front plate, a ratcheting plate, a ratcheting dog, a pivot fastener, a ratcheting dog fastener, and padding. The ratcheting plate forms ratcheting teeth that engage with the ratcheting dog while the handles are moved inward.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(5) Embodiments of the Compression Stocking Donning Aid 100 (Aid) are comprised of a handle assembly 110, a bracket assembly 200, and a sock applicator assembly 120.

(6) The handle assembly 110 is comprised of two, mirror image handles 102 that are covered by handle grips 101. The two handles 102 are weldedly connected to the bracket assembly 200. The handles are essentially linear elongated cylinders that allow the user of the Aid 100 to grasp the Aid and apply the necessary leverage to open the compression stocking for application. The handles 102 are comprised of cold rolled steel rods and covered with 7 black closed cell vinyl foam grips with a wall thickness of 0.12 to 0.15 to insulate, cushion, and aid in gripping and compressing the handles 102.

(7) The sock applicator assembly 120 is comprised of two sock applicators 104. The sock applicators 104 are each comprised of cylinders formed in a S shaped curve terminated with end terminators 103. The sock applicators 104 are comprised of cold rolled steel rods and integral to the handles 102. A handle 102 and its integral sock applicator 104 are essentially planar. At the end of the sock applicators 104, the steel rod forms a flattened end 404 and a threaded aperture 401 in the flattened end 404. The end terminators 103 are attached to the sock applicators via a fastener and the threaded aperture 401. In an embodiment the end terminators 103 are wide by high rubber tips 402 that prevent the device from slipping on the floor when the user inserts their foot. The rubber tips 103 are secured to the end of sock applicators 104 with a fastener 403 that is flush to the sock applicators 104.

(8) The bracket assembly 200 is comprised of a back plate 201, a front plate 202, a ratcheting plate 203, a ratcheting dog 207, a pivot fastener 204, a ratcheting dog fastener 206, and padding. The bracket assembly 200 is constructed of steel and weldedly affixed to the handles 102 as described further below.

(9) The back plate 201 and a front plate 202 are identical in shape. The back plate 201 and the front plate 202 are essentially rectangular plates but with one end of the plates linear and the other end of the plates curved. The straight ends of the back plate 201 and a front plate 202 are weldedly affixed to one of the handles 102 allowing an interior gap between the two plates. The interior gap between the back plate 201 and a front plate 202 provides a path for the ratcheting plate 203 to slide as the handles 102 are moved inward and outward. The back plate 201 and the front plate 202 move together as the handles 102 are opened and closed.

(10) The ratcheting plate 203 is essentially rectangular shaped with one end of the plate linear and the other end of the plate curved. The ratcheting plate 203 is comprised of and forms ratcheting teeth 205 that engage with the ratcheting dog 207 while the handles 102 are moved inward relative to each other to provide intermediate stopping points along the range of motion of the handles 102 when the handles are compressed. This is what causes the compression stocking to expand. The straight end of the ratcheting plate 203 is weldedly affixed to one of the handles. As discussed in more detail below, when the entire Aid is inverted, the ratcheting dog 207 is disengaged from ratcheting teeth 205 allowing the handles to be expanded and readied for the next use. The ratcheting dog 207 is affixed via the ratcheting dog fastener 206 which passes through the back plate 201 and the front plate 202. The opening 208 formed by the ratcheting plate 203 allows the ratcheting dog 207 to move freely between the back plate 201 and front plate 202.

(11) The pivot fastener 204 passes through the back plate 201, the front plate 202, and the ratcheting plate 203 to secure all three plates together. The pivot fastener 204 allows the ratcheting plate 203 to move around the axis provided by the pivot fastener 204 and independently from the back plate 201 and the front plate 202.

(12) The side of bracket assembly 200 that faces the user's shins will be covered with padding. This padding is comprised of thick foam rubber bumper with adhesive backing and is constructed of black closed cell crosslinked polyethylene foam. The purpose of the padding is to protect a user's shins in the event the user moves their foot through the sock and contacts the bracket assembly 200. The padding will form apertures to allow for the bolts to fit flush with the padding. The padding will comprise one or more stickers containing product and marketing information.

(13) The bracket assembly 200 serves as the fulcrum for the two handles 102. As the user pushes the handles 102 towards each other, the sock applicators 104 are forced outward, the compression stocking is expanded allowing the user to insert his foot. The bracket assembly 200 securely opens and locks the sock applicators 104 to allow the user to insert their foot into the sock without slippage.

(14) The center of gravity of the ratcheting dog 207 is offset from the location of the ratcheting dog fastener 206. When the Aid 100 is upright, with the sock applicator assembly 120 located on or near the ground, the ratcheting dog 207 is engaged with the ratcheting teeth 205. When the Aid 100 is inverted, the ratcheting dog 207 is disengaged with the ratcheting teeth 205. The shape of the pawl 209 of the ratcheting dog 207 is shaped so that as the handles are compressed towards each other the pawl 209 slides over the teeth, but engages with the ratcheting teeth 205 and prevents backward motion. This allows the ratcheting teeth 205 and pawl 209 to allow for intermediate stopping points as the compression stocking is expanded. When the Aid 100 is turned upside down, the ratcheting teeth 205 disengage with the ratcheting dog 207 allowing the handles to open thereby readying the Aid 100 for the next use.

(15) In an embodiment of the Aid 100 all of the metallic materials are zinc dip coated.

(16) To use the Aid 100, the user disengages the ratcheting dog 207 from the ratcheting teeth 205 by inverting the Aid 100, which allows gravity to drop the pawl 209 away from the ratcheting teeth 205 and allows the user to expand the handles 102, which simultaneously brings the sock applicators 104 together. A compression stocking is then placed over the bottom portion of the sock applicators 104 of the sock assembly 120. The user then compresses the handles 102 to expand the sock applicator assembly 120 and the compression stocking. As the handles 102 are compressed, the pawl 209 on the ratcheting dog 207 engages with successive ratcheting teeth 205 which locks the handles 102 and the sock applicator assembly 120 in place. Additional pressure on the handles 102 causes the sock applicator assembly 120 to expand further and causes the pawl 209 on the ratcheting dog 207 to lock the expansion temporarily in place. The user easily inserts their foot into the compression sock and presses their foot forward through the sock until the sock slips entirely off the sock applicators 104 onto the foot. The user then sets the Aid 100 aside and rolls the compressing stocking upward and over the calf.
