Multi-adjustable wrist brace

[0001] This invention relates generally to wrist braces, and more particularly to improvements in braces enabling ease and readiness of attachment and tightening about the wrist of the wearer, as well as closeness of fit to different sizes of wrists, and retention between the thumb and forefinger of the user.

[0002] Prior wrist braces lacked the unusually advantageous combinations of features referred to, as well as the wide ranges of fit and adjustability both about the wrist, and also over the zone between the thumb and forefinger. There is need for the multiple improvements in a wrist brace as is now afforded by the invention.

[0003] It is a major object of the invention to provide a wrist brace construction and configuration meeting the above need. Basically, the improved wrist brace comprises:

• • [0004] a) a flexible holder to receive the user's wrist and having two flaps adapted to be closed toward one another to secure the holder about the wrist,
  • [0005] b) tightening strands associated with the flaps, and having anchored ends bodily adjustable relative to at least one of said flaps,
  • [0006] c) a puller connected with all the strands to be pulled to tension the strands as the flaps are moved toward one another, the puller then being adjustably connectible to the holder to adjustably tension all of the pulled strands,
  • [0007] d) and a flexible auxiliary strap connected to the holder to be adjustably folded over a zone between the user's thumb and forefinger, for adjustable connection to the holder, for firmly anchoring the holder in position on the wrist.

[0008] It is another object to provide an improved wrist brace as referred to wherein the puller and holder carry connective material, which typically includes hook and pile components, the connective material carried by the holder being distributed over an area which is much greater than the area of the connective material on the puller.

[0009] Yet another object is to provide a wrist brace in which the flexible auxiliary strap also carries connective material which adjustably attaches to the connective material on the holder.

[0010] An additional object is to provide for adjustable anchoring of the strands to the second of the two flaps in spaced relation to the auxiliary strap.

[0011] Additional objects include provision of between 4 and 6 strands merging toward and connected to the one puller which itself has the form of a flexible strap; the provision of a holder which has flexible U-shaped cross section; and the provision of of strand passage through one of the two flaps, the other of the two flaps including a main flap, there being an over-flap detachably and adjustably carried by the main flap, the strands having anchored connection to that over flap, to adjustably position and anchor the strand ends relative to said other flap. Also, the puller is configured to be adjustably attached to the over flap, whereby multiple adjustments maximize comfort and bracing effect.

[0012] These and other objects and advantages of the invention, as well as the details of an illustrative embodiment, will be more fully understood from the following specification and drawings, in which:

[0019] In the drawings, the preferred brace 100 includes an elongated flexible holder, in the form of a sleeve 11, is sized to loosely receive the user's or wearer's wrist 12. The sleeve includes two flexible flaps, first flap 11a and second flap 11b, adapted to be relatively closed toward sides of the wrist to secure the holder sleeve about the wrist.

[0020] Tightening or tensioning strands 13 are associated with the flaps. They are effectively anchored at end locations 13a to the flap 11a when the holder is secured about the wrist, and then extend at 13b between the flaps and through openings 13c in flap 11b. The strands then extend at 13d, and convergently in FIG. 1, toward a tightener flap 14 to which the strands are end connected at locations 13e, in merged condition. Flap 14 may be elongated, as in FIGS. 1 and 2. The locations 13a are spaced apart at substantially equal intervals lengthwise of the flap 11a and sleeve; openings 13c are likewise spaced apart at substantially equal intervals along flap 11b the same as the intervals between locations 13a. Accordingly, only one tightener 14 is required to be hand manipulated, by pulling force, for adjustably tightening all of the strands as the flaps 11a and 11b are moved toward one another, and fastened. Also, angular movement of the tightener flap, in direction 101 or direction 102, i.e. lengthwise of the sleeve, during such pulling, achieves lesser or greater tightening of different strands, for adjusting the securing of the holder to the wrist configuration of the user, for maximum comfort consistent with optimum security, and bracing effect. Spaced apart stiffening inserts (to be more fully described) in the sleeve, as at 45 in strand anchoring over-flap 20, can be employed to assist in such bracing; however, they are also subject to the referenced adjustment of different portions of the holder to the wrist configuration, to assist in obtaining the optimum adjusted bracing or immobilizing effect, consistent with comfort. This obviates any need for a rigid or semi-rigid sleeve, which would not be nearly as conformable to the wrist configuration.

[0021] It is a feature of the invention that the carriage of the strands at end locations 13a is made to be adjustable, whereby all of those end locations are simultaneously adjustable in position, and all of the opposite end locations 13e of the strands are simultaneously adjustable in position by the tightener 14 relative to adjusted end locations 13a, affording a very high degree of adjustability. Adjustment of both ends of the strands is thereby achieved. For this purpose, the strands at end locations 13a are preferably anchored in position to an over flap 20, or sub-flap, which is adjustably attached or attachable (face to face) to a main flap 21. The latter functions as a part of flap 11a when the brace is attached to the wrist. As shown in FIG. 1 the tightener flap 14 is attachable to and over the over flap 20, to assist in its attachment to the main flap 21, a local part of flap 11a, providing a self-restraining, unitary, layered assembly of elements, held in adjusted relative positions for comfort, security and maximum bracing effect.

[0022] The elements which are retained together in face to face relation may employ connective, or hook and pile material, as follows:

• • [0023] wide area connective material 22 on flap 11a (for example extending along 11a and near opposite ends of 11a)
  • [0024] a band 23a of connective material (see FIG. 4) on the inner side of over-flap 20, to press connect to material 22 in different positions of 20 (see FIG. 1)
  • [0025] a band 24 of connective material on the opposite (outer) side of over-flap (see FIG. 1)
  • [0026] a band 25 of connective material on the inner side of puller flap 14 (see FIG. 4), to press connect to selected part or parts of band 24 (note elongation of band 24 and of the over-flap, to provide for or enable such selected postion adjustment.

[0027] Also provided, if required, is a flexible auxiliary strap connected to the holder to be adjustably folded over a zone between the user's thumb and forefinger, for adjustable connection to the holder, for firmly anchoring the holder in position on the wrist. See strap 30, having an end portion 30a attached to flap 11b, and elongated to extend over zone 31 between the thumb 32 and forefinger 33 of the wearer. Strap 30 has an end portion 30b carrying connective (hook or pile) material 34 that is adjustably press-attachable to the material 22 on flap 11a, and/or to exposed material 24 on the over flap 20.

[0028] If desired, plastic or metallic stiffeners may be provided in the elongated flexible material of the over flap 20 as referred to above. See broken lines 45.

[0029] Also shown is a flexible web 40 that interconnects the two flaps 11a and 11b, to hold them in spread apart, U-shaped connection, for insertion of the user's wrist, at the time of brace fitting to the wrist. Web 40 is typically spaced downwardly within the U-shaped configuration of the flaps 11a and 11b.

[0030] FIG. 6 shows a flexible flap extension 60 receiving the user's thumb 61. Extension 60 is shown as integral with flap 11b, and may include a wrap-around VELCRO connected strap 60a. An elongated metallic stiffener 63 is associated with flap 11b. A stiffener extension 63a extends at the flap extension 60 to brace the thumb 61. Extension 63 may be received in a pocket in the flap material.
