The present disclosure concerns a sock having pluralities of weight assemblies at a leg of the sock. Each weight assembly measured along a circumferential direction about the leg of the sock, extends for more than 0.25 and less than 0.5 of the circumference of the leg of the sock. Preferably each weight assembly extends 0.33 of the circumference of the sock. Each weight assembly has a plurality of weight carriers and a plurality of weights. Each weight carrier of an assembly carries a weight of the assembly.
Increased neuromuscular feedback, increased proprioception of bilateral lower extremities and increased tactile feedback are phenomenal therapy tools for the client needing sensory integration strategies included in their treatment plan. Adding increased weight to bilateral lower extremities assists the central nervous system in knowing where the individual foot is in space (proprioception) as well as improving the clients tactile input. Increased weight on bilateral lower extremities assists individuals with neuromuscular-skeletal injuries to walk with improved neuromuscular feedback, improved alignment, and improved coordination.

U.S. Pat. No. 5,027,440, John A. Morris, discloses various weight loss systems and methods and weighted distal limb sleeves for promoting non-exercise activity thermogenesis (NEAT). One embodiment is an anatomically-weighted distal limb sleeve for use in a weight loss program. One such anatomically-weighted distal limb sleeve is adapted and sized to be comfortably worn on a distal portion of a person's limb relative to a limb joint. The anatomically-weighted distal limb sleeve comprises a predefined amount of exogenous weight arranged on the limb sleeve to simulate the anatomical distribution of endogenous soft tissue of the distal portion of the limb.
Some known ankle weights used to address increasing neuromuscular feedback, increasing proprioception of bilateral lower extremities, and increasing tactile feedback add bulk around the ankle joint and this bulk decreases the ability of the weight to work correctly for this population, as it disturbs the normal gait cycle. The result is an abducted gait pattern with increased circumduction during the swing phase of the gait cycle. Some products on the market place weight pouches on client's shoe laces. This places weight in an unnatural position and interferes in the normal gait cycle. Still other products place weights in pouches on the lateral side of the leg. This provides an unnatural placement of weight, disturbing the gait cycle.
The weighted sock of the present disclosure provides for improved sensory integration of legs. The sock's streamlined design, light total weight, and specific placement of the weights ensures the sock will not disturb the normal gait pattern of a child or adult. It may be worn for multiple hours at a time comfortably by children or adults of any age. The socks are completely machine washable and dryable allowing many years of use. The metal in the socks is non-toxic and rust proof. The socks slip on and off, just like regular socks.
The weighted sock is also useful in strengthening the user's bilateral lower extremity musculature.
Accordingly, an example of the invention comprises a weighted sock. The weighted sock has an open end and a closed end. A weight assembly of the weighted sock is at a portion of the sock. The weight assembly has a weight carrier. The weight carrier has a carrier space. A weight is in the carrier space. The weight is configurable to take on a first shape or dimension by a force which also changes the shape or dimension of the weight carrier. The carrier when having the changed shape or dimension provides a force of sufficient magnitude to reconfigure the weight into a second shape or dimension different from the first shape when the force which also changes the shape or dimension of the carrier is removed.

Within each carrier enclosed space 38, each mass unit 42 in that carrier enclosed space is movable within a fixed range relative to each other mass unit 42 in that carrier enclosed space 38.
The following description of weight, mass units, carrier, and portion(s) of material applies to all the weights, mass units, carriers, and portions of material of the weight assembly. A single weight carrier and its respective weight, mass units, and first and second portions of material are sometimes described for conciseness and ease of description. The weight 40 and mass units 42 associated with each carrier 24, 25,26,27,28,29,30 are the same. The first 24e, 25e, 26e, 27e, 28e, 29e, 30e and second 24f, 25f, 26f, 27, 28f, 29f, 30f portions of material associated with each carrier are the same. The carrier spaces 38 associated with each carrier 24, 25, 26, 27, 28, 29, 30 are the same. The term same means essentially the same construction, shape and dimension. Each of the plurality of mass units 42, when their associated carrier 24, 25, 26, 27, 28, 29, 30 or portion(s) of material 24e, 25e, 26e, 27e, 28e, 29e, 30e; 24f, 25f, 26f, 27, 28f, 29f, 30f are stretched to expand in a direction under a force, is moveable along with the carrier or portion(s) of material stretched. They are moveable from a position and in the direction of expansion. The mass units are moveable relative to the other mass units of the plurality, when the units are in the carrier space. The direction of expansion is, capable of being in at least in the Z and/or −Z direction relative to the Z axis. The direction of expansion can also be in the Y and/or −Y direction relative to the Y axis. When the force stretching the carrier 24, 25, 26, 27, 28, 29, 30 or portion(s) of material 24e, 25e, 26e, 27e, 28e, 29e, 30e; 24f, 25f, 26f, 27, 28f, 29f, 30f is removed from the carrier or portion(s) of material, an elastomeric force contracts the stretched carrier or portion(s) of the material in a direction opposite the direction of expansion, returning the carrier or portion(s) of material to a more relaxed state; the elastomeric force also moving the moved mass unit 42 in the direction of contraction.
Each weight 40, comprising the individual mass units 42, is configurable to take on a first shape or dimension under a force of change which also changes the shape or dimension of their respective carrier 24, 25, 26, 27, 28, 29, 30 or portion(s) of material 24e, 25e, 26e, 27e, 28e, 29e, 30e; 24f, 25f, 26f, 27, 28f, 29f, 30f from their shape or dimension when not under the force. The changed shape or dimension of the carrier or portion(s) of material has a stored force of sufficient magnitude to return the carrier or portion(s) of material towards their first shape or dimension when not under the force of change. The force of sufficient magnitude also reconfigures the weight 40 into a second shape different from the first shape as the carrier 24, 25, 26, 27, 28, 29, 30 or portion(s) of material 24e, 25e, 26e, 27e, 28e, 29e, 30e; 24f, 25f, 26f, 27, 28f, 29f, 30f return towards their shape when not under the force of change. The second shape being a shape of the weight when not under change or at least more like the shape of the weight when not under the force of change. The stored force of sufficient magnitude in one example is an elastomeric force. The changed shape or dimension of the carrier or portion(s) of material includes an expanded portion caused by a stretching of an elastomeric portion of the carrier or portion(s) of material. Accordingly, the weight 40 can take on a first shape when the carrier 24, 25, 26, 27, 28, 29, 30 or portion(s) of material 24e, 25e, 26e, 27e, 28e, 29e, 30e; 24f, 25f, 26f, 27, 28f, 29f, 30f are stretched. The stretched carrier or portion(s) of material have an elastomeric force of sufficient magnitude to reconfigure the weight 40, comprising the individual mass units, from the first shape or dimension into a second shape or dimension when the carrier or portion(s) of material is not under the force stretching the carrier or portion(s) of material. The first shape or dimension can be a curved shape curving at least partially about a line extending in the Z, and/or −Z directions. The second shape or dimension can be a less curved, more flat shape. The second shape is more like the shape of the weight when not under the force stretching. The first shape or dimension can have a twist. The twist can be relative to and at least partially about a line extending in the X and/or −X direction relative the X axis. The second shape or dimension can be less twisted, flatter, than the first shape.

The length of the weight assembly from border 44 to 46 is about 2 inches. Adjacent the first end carriers' 24 first end 24a is a border 48 outside the carrier space 38 which comprises a first material overlapping a second material. The first material is coupled to the first portion of material 24e and extends from and is part of the first portion of material 24e. The second material is coupled to the second portion of material 24f and extends from and is part of the second portion of material 24f. Adjacent the second end weight carrier 30 second end 30b is a border 50 outside the carrier space 38 which comprises a first material overlapping a second material. The first material is coupled to the first portion of material and extends from and is part of the first portion of material 30e. The second material is coupled to the second portion of material and extends from and is part of the second portion of material 30f. The length of the weight assembly from border 48 to border 50 is about 5.5 inches.
The weight assembly 22 is disposed between an exterior material 52 of the sock leg 20a and an interior material 54 of the sock leg 20a. The sock leg has the open end 34. The open end is distal the sock foot 20b. The weight assembly 22 is coupled to the interior material 54 by stitches going through the border 48 at the first end 24a of the first end weight carrier 24 and the border 50 at the second end 30b of the second end weight carrier 30. A second 222 and third 322 weight assembly are disposed between the exterior material 52 and interior material 54 of the sock leg 20a. The second 222 and third 322 weight assemblies are the same as the first weight assembly 22. Each weight assembly has the same construction, shape, and dimension. Each weight assembly, measured along a circumferential direction about the leg 20a of the sock, extends for more than 0.25 and less than 0.5 of the circumference of the leg 20a of the sock. Preferably each weight assembly extends 0.33 of the circumference of the sock leg 20a when the sock leg is at rest. Each weight assembly has a border 44 or 46 spaced from, in the circumferential direction, an adjacent border 44 or 46 of an adjacent weight assembly. The spacing between adjacent borders 44, 46 of adjacent weight assemblies is the same for all adjacent borders.
Having the weight assemblies 22, 222, 322 between the exterior material 52 and interior material 54 of the sock leg 20a helps conceal the weight assemblies; giving the sock an ordinary appearance. Having a sock with a more ordinary appearance helps remove the stigma of having a therapeutic sock. It is also believed having interior material 54 shrouding the weight assemblies 22, 222, 322 improves comfort. Notably, the spacing between adjacent borders of adjacent weight carriers is equidistant. Of course, to save material, the interior material 54 of the sock 20 could be made up of the second portions of material of the weight assemblies, for example made of second portions 24f, 25f, 26f, 27f, 28f, 29f, 30f of weight assembly 22. The exterior material 52 could still shroud the first portions of material of the weight assemblies, for example portions 24e, 25e, 26e, 27e, 28e, 29e, 30e of weight assembly 22. Alternatively, the exterior material 52 could form the first portions of material of the weight assemblies, for example portions 24e, 25e, 26e, 27e, 28e, 29e, 30e of the weight assembly 22. The interior material 54 could shroud the weight assemblies. As opposed to having a weight assembly 22, 222, 322 disposed between the exterior 52 and interior materials 54 of the sock leg 20a, the exterior 52 and interior 54 sock material of the sock leg 20a could form the weight carriers of the weight assemblies. In this case stitching would join the exterior material 52 to the interior material 54 to form the seams of the carriers at the carriers' first end, second end, third end, and fourth end. Weight assemblies 222 and 322 follow the same nomenclature as weight assembly 22 except a 222 precedes reference numbers for assembly 222. Thus, the first end carrier is labeled 22224. Thus, the first carrier of assembly 322 is labeled 32224. The sock leg 20a or leg of the sock 20a refers to the portion of the sock that receives the leg of a user and terminates at the users' ankle. The closed end 36 of the sock is at the toe portion 20c of the sock 20. The toe portion 20c of the sock is the portion of the sock that receives the toes. The heel portion 20d of the sock is the portion of the sock that receives the heel. The heel portion is closed. The foot portion 20b of the sock is the portion of the sock that receives the foot of the sock. The foot 20b of the sock has the toe portion 20c and heel portion 20d. Both the heel and toe are closed.
A second weighted sock, the same as the first weighted sock, is provided to provide pairs of weighted socks where each sock is the same.
