Title: Wrist protecting band

Description:
TECHNICAL FIELD 
     The present disclosure relates to a wrist protecting band. More particularly, the present disclosure relates to a wrist protecting band, in which compression pads are used to compress only the ulna area and the radius area of the wrist toward the center of the wrist, thereby enabling the wrist protecting band to prevent side effects, such as hand tingling or hand swelling, and reliably perform a wrist protecting function. Coupling force between compression members pivotably coupled to each other is adjusted by a user&#39;s manipulation so as to adjust a compression load applied to the ulna area and radius area of the wrist, thereby enabling the wrist protecting band to be more conveniently and optimally used according to user requirements. The overall diameter of the wrist protecting band may be increased or reduced, so that the process of attaching or detaching the wrist protecting band to or from the wrist may be performed more conveniently. It is possible to compress or decompress the wrist by pivoting the compression members in a simple manner using a dial-type manipulator while adjusting the strength of compression a simple manner using the manipulator. 
     BACKGROUND ART 
     Regarding the joints of an arm of a human body, the radius and the ulna constitute the forearm, eight (8) carpal bones constitute the wrist, five (5) metacarpal joints by which pivoting, flexing, and extension are enabled constitute the palm, and phalangeal bones constitute each finger while providing a function of gripping an object to the finger. 
     Such joints may be injured by repeated and continuous excessive use thereof due to operations of holding objects with hands or due to activities. In some cases, injured joints may not be completely healed and continuous pain may occur. 
     Therefore, wrist protecting bands respectively attached to a wrist of a human body to protect such joints and bones have been proposed and used. 
     In general, a wrist protecting band is configured to be attached to a frail joint portion of a person like an elbow protector, an ankle protector, a forearm protector, and the like. 
     A typical wrist protector of the related art has the shape of a band surrounding a wrist, and is placed along the outer surface of the wrist to uniformly compress the wrist and portions adjacent to the wrist. The wrist protector serves to protect the wrist by compressing the wrist and prevent the wrist from being excessively bent. 
     However, because a wrist protector of the related art uniformly compresses the entire area of the wrist, if the wrist protector has been attached to the wrist for an extended period of time, blood may not flow through the wrist artery properly, thereby causing the hand to tingle or swell, which is problematic. Due to the problem, such as hand tingling, the use of the wrist protector is limited. For example, a user may remove the wrist protector during or before driving. Accordingly, the wrist may be exposed to the danger of an injury during a variety of exercises or activities, instead of being safely protected.

     MODE FOR INVENTION 
     Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Throughout this document, reference should be made to the drawings, in which the same reference numerals and symbols will be used to designate the same or like components. In the following description of the present disclosure, detailed descriptions of known functions and components incorporated herein will be omitted in the case that the subject matter of the present disclosure may be rendered unclear thereby. 
       FIG. 1  is a perspective view schematically illustrating the shape of a wrist protecting band according to embodiments of the present disclosure,  FIG. 2  is a perspective view schematically illustrating the detached state of the wrist protecting band according to embodiments of the present disclosure,  FIG. 3  schematically illustrates compression load adjusting states of the wrist protecting band according to embodiments of the present disclosure, and  FIG. 4  is a cross-sectional view schematically illustrating an internal structure of a manipulating portion of the wrist protecting band according to embodiments of the present disclosure. 
     The wrist protecting band according to embodiments of the present disclosure is configured to be attached to a wrist H of a user to reliably protect a wrist without side effects, such as hand tingling, and includes a first compression member  110 , a second compression member  120 , a connecting member  130 , and a coupling body  300 . 
     The first compression member  110  and the second compression member  120  are configured such that the inner surfaces thereof are concavely curved to surround the wrist H. A first compression pad  210  and a second compression pad  220  are disposed on inner surface portions such that the first compression pad  210  and the second compression pad  220  can compress the area of the ulna H 1  and the area of the radius H 2  of the wrist toward the center of the wrist. Both end portions of the connecting member  130  are pivotably coupled to one end portion of the first compression member  110  and to one end portion of the second compression member  120  to connect the first compression member  110  and the second compression member  120 . 
     For example, the first compression member  110  may be disposed such that the first compression pad  210  compresses the area of the radius H 2  of the wrist toward the center of the wrist while surrounding the area of the radius H 2 , and the second compression member  120  may be disposed such that the second compression pad  220  compresses the area of the ulna H 1  of the wrist H toward the center of the wrist while surrounding the area of the ulna H 1 . The connecting member  130  is pivotably coupled to one end portion of each of the first compression member  110  and the second compression member  120  to connect the first compression member  110  and the second compression member  120 . 
     The coupling body  300  is configured such that the other end portion of the first compression member  110  is pivotably coupled to one end portion of the coupling body  300  and the other end portion of the second compression member  120  is coupled to or decoupled from the other end portion of the coupling body  300  in response to a user&#39;s manipulation. 
     In the wrist protecting band configured as above, the area of the ulna H 1  and the area of the radius H 2  of the wrist H are compressed by the first compression pad  210  and the second compression pad  220  of the first compression member  110  and the second compression member  120 . Here, the wrist protecting band is configured such that the wrist other than the area of the ulna H 1  and the area of the radius H 2 , is not compressed by any portion thereof. That the wrist protecting band may be configured such that the portions of the wrist protecting band, other than the area of the ulna H 1  and the area of the radius H 2 , are in simple contact with the wrist H, instead of being spaced apart from. the wrist H or compressing the wrist H. 
     Accordingly, since the area of the ulna H 1  and the area of the radius H 2  of the wrist H are compressed by the first compression pad  210  and the second compression pad  220 , the wrist protecting band according to embodiments of the present disclosure can supplement the fixing force of the wrist H to reliably perform a wrist protecting function of, e.g. preventing the wrist from being excessively bent and reducing pain in the wrist. Here, no portions of the wrist H, other than the area of the ulna H 1  and the area of the radius H 2 , are compressed by the first compression pad  210  and the second compression pad  220  are compressed to obstruct the circulation of blood. Accordingly, no side effect, such as hand tingling or hand swelling, may occur. 
     In addition, health supplement members  500  formed from zirconium (Zr), germanium (Ge), or the like may be inserted into the first compression pad  210  and the second compression pad  220  in order to apply a variety of health supplement functions to the wrist. 
     In addition, the first compression member  110  is pivotably coupled to one end portion of the coupling body  300 , and the second compression member  120  is disposed to be coupled to or decoupled from the other end portion of the coupling body  300 . Here, the second compression member  120  is configured such that the coupling state thereof can be adjusted by the user&#39;s manipulation, so that compression load of the first compression member  110  and the second compression member  120  on the area of the ulna H 1  and the area of the radius H 2  is adjusted. 
     More specifically, the other end portion of the coupling body  300  has an insertion guide hole  310 , such that the other end portion of the second compression member  120  may be inserted into and coupled to the insertion guide hole  310 . A manipulator  400  operable by the user is disposed in the central portion of the coupling body  300 . The manipulator  400  is configured such that the manipulator  400  may adjust a depth to which the second compression member  120  is inserted into and coupled to the insertion guide hole  310 . 
     Here, a separate connecting wire W may be coupled to, while penetrating, the other end portion of the second compression member  120  so as to be connected to the manipulator  400  of the coupling body  300 . The connecting wire W may be drawn by the manipulation of the manipulator  400 , so that the second compression member  120  is inserted into the insertion guide hole  310 . 
     According to this configuration, the manipulator  400  of the coupling  300  may be manipulated to release the connecting wire W from the drawn state, so that the second compression member  120  is decoupled from the coupling body  300  as illustrated in  FIG. 1 . In contrast, the manipulator  400  of the coupling body  300  may be manipulated to draw the connecting wire H, so that the second compression member  120  may be coupled to the coupling body  300  as illustrated in  FIG. 1 . 
     The wrist protecting band as described above constantly maintains the overall shape of a ring, since the second compression member  120  is connected to the coupling body  300  via the connecting wire W even in a case in which the second compression member  120  is decoupled from the coupling body  300 . In an open state in which the second compression member  120  is decoupled from the coupling body  300  as illustrated in  FIG. 2 , the wrist is located in the direction of penetration of the internal space of the wrist protecting band. Afterwards, as illustrated in  FIG. 1 , it is possible to compress the wrist H by drawing the drawing wire W by manipulating the manipulator  400 . 
     Here, the members pivot about three rotary shafts M, including the rotary shaft M of the coupling body  300  of the first compression member  110 , the rotary shaft M of the first compression member  110  of the connecting member  130 , and the rotary shaft M of the connecting member  130  of the second compression member  120 , the wrist protecting band may expand or contract the entire internal space. Thus, when the wrist H is inserted into or removed from the internal space of the wrist protecting band, the wrist H may be more conveniently moved. 
     In addition, it may be necessary to use different types of the wrist protecting band depending on the thickness of the wrist H. In this case, it is possible to adjust the internal space of the wrist protecting band to have different diameters by fabricating the first compression member  110  and the second compression member  120  to have the same sizes, fabricating the connecting member  130  may to have different lengths, and coupling the connecting member  130  to the first compression member  110  and the second compression member  120 . 
     In addition, the compression load on the area of the ulna H 1  and the area of the radius H 2  of the first compression member  110  and the second compression member  120  is adjusted by adjusting the depth to which the second compression member  120  is inserted into the insertion guide hole  310  by the manipulation of the manipulator  400 . For example, as illustrated in (a) in  FIG. 3 , when the manipulator  400  is manipulated so that the second compression member  120  inserted relatively deeply into the insertion guide hole  310 , the compression load of the first compression member  110  and the second compression member  120  on the area of the ulna H 1  and the area of the radius H 2  relatively increases. As illustrated in (b) in  FIG. 3 , when the manipulator  400  is manipulated so that the second compression member  120  is inserted relatively shallowly into the insertion guide hole  310 , the compression load of the first compression member  110  and the second compression member  120  on the area of the ulna H 1  and the area of the radius H 2  relatively decreases. 
     In addition, the manipulator  400  includes a fixed body  410 , a rotary body  430 , and a dial knob  420 . The fixed body  410  is fixedly coupled to the coupling body  300 , and has a ratchet  411  provided on the inner circumference of the top end portion of the fixed body  410 . The rotary body  430  is coupled to the fixed body  410  so as to be movable in a top-bottom direction. A stopper protrusion  431  provided on one portion of the rotary body  430  engages with the ratchet  411  to restrain unidirectional rotation during downward movement. The engagement of the stopper protrusion  431  and the ratchet  411  is released during upward movement. The dial knob  420  is coupled to the rotary body  430  to move in a top-bottom direction and rotate together with the rotary body  430 , and is configured to be manipulated by the user. The connecting wire W coupled to, while penetrating, the second compression member  120  is configured to be wound on the rotary body  430  in a single direction. 
     Accordingly, in a case in which the dial knob  420  is moved downwardly by pressure, when the dial knob  420  is rotated, for example, in the clockwise direction, the rotary body  430  rotates together with the dial knob  420 , and the connecting wire W is wound on the rotary body  430 . Accordingly, the connecting wire W is drawn toward the coupling body  300 , so that the second compression member  120  is inserted into and coupled to the insertion guide hole  310 . In this state, the stopper protrusion  431  is engaged with the ratchet  411  of the fixed body  410 , and thus, the rotation of the rotary body  430  the opposite direction is restrained. Accordingly, in response to the dial knob  420  being manipulated to rotate, the second compression member  120  is continuously and more deeply inserted into the insertion guide hole  310 , so that the compression load on the area of the ulna H 1  and the area of the radius H 2  is increased, and this state is maintained. 
     In contrast, to reduce the compression load on the area of the ulna H 1  and the area of the radius H 2  or to decouple the second compression member  120  from the coupling body  300 , the dial knob  420  may be drawn upwardly to decouple the stopper protrusion  431  of the rotary body  430  from the ratchet  411  of the fixed body  410 . In this state, the second compression member  120  may be rotated and moved in a direction in which the second compression member  120  is decoupled from the coupling body  300 , or the dial knob  420  may be rotated in the counterclockwise direction. 
     In addition, the insertion guide hole  310  of the coupling body  300  may be provided with a wire guide  320  to guide a connection path of the connecting wire W so that the connecting wire W of the second compression member  120  is connected to the manipulator  400  while being wound on the rotary body  430 . The wire guide  320  may be provided to guide the connecting wire W, penetrating the second compression member  120 , to both side peripheral portions of the insertion guide hole  310 . 
     In addition, the fixed body  410  may be provided with wire inlets  412  to guide the connecting wire W along penetration paths, so that the connecting wire W extending from the second compression member  120  is wound on the rotary body  430  by passing through the wire inlets  412 . The wire inlets  412  may be provided on locations adjacent to the both side peripheral portions of the insertion guide hole  310  while having a shape corresponding to the wire guide  320 . 
     Since the arrangement of the connecting wire W is maintained along a predetermined path by the wire guide  320  and the wire inlets  412 , the connecting wire W may be reliably maintained in position, without problems, such as twisting or entangling, even in a case in which the second compression member  120  is coupled to or decoupled from the coupling body  300 . 
       FIG. 5  schematically illustrates various shapes of the compression pads of the wrist protecting band according to embodiments of the present disclosure. 
     As illustrated in  FIG. 5 , the first compression pad  210  and the second compression pad  220  according to embodiments of the present disclosure may be provided with a variety of shapes. 
     For example, as illustrated in (a) in  FIG. 5 , the length L 1  of the second compression pad  220  that compresses the area of the ulna H 1  may be greater than the length L 2  of the first compression pad  210  that compresses the area of the radius H 2 . The bones constituting an arm include the ulna H 1  and the radius H 2 . In the wrist H, the ulna H 1  and the radius H 2  protrude outwardly. The ulna H 1  is thicker than the radius H 2 , and has a wider protruding area in the wrist H than the radius H 2 . Since the area of the ulna H 1  is relatively wider, it may be more appropriate to compress the area of the ulna H 1  and the area of the radius H 2  if the length of the second compression pad  220  compressing the area of the ulna H 1  is set to be greater. 
     In addition, as illustrated in (b) in  FIG. 5 , the first compression pad  210  and the second compression pad  220  may be configured such that surfaces of longitudinally intermediate portions thereof, to be in contact with the wrist H, may be concavely curved. That is, in a case in which the first compression pad  210  and the second compression pad  220  have a uniform thickness, the surfaces to be in contact with the wrist H may be formed along lines S 1  to be parallel to the curves of the inner surfaces of the first compression member  110  and the second compression member  120 . In contrast, according to embodiments of the present disclosure, the surfaces to be in contact with the wrist H may be formed along lines S 2  having a concavely curved shape. Since the surfaces to be in contact with the wrist H are formed to be concavely curved, the first compression pact  210  and the second compression pad  220  may be more closely in contact with the wrist H, thereby more reliably compressing the ulna area and the radius area of the wrist H. 
       FIGS. 6 and 7  schematically illustrate a compression pad moving structure of the wrist protecting band according to embodiments of the present disclosure. 
     As illustrated in  FIGS. 6 and 7 , the first compression pad  210  and the second compression pad  220  according to embodiments of the present disclosure may be disposed to be movable by predetermined distances in the longitudinal directions of the first compression member  110  and the second compression member  120 . Accordingly, the positions of the first compression pad  210  and the second compression pad  220  may be adjusted, so that the areas of the ulna and the radius, which may differ depending on the user, can be accurately compressed. 
     When the wrist protecting band is attached to the wrist H, the first compression pad  210  and the second compression pad  220  are disposed opposite to each other to compress the area of the ulna H 1  and the area of the radius H 2  of the wrist H. Here, since the shape of the wrist H, the positions of the ulna H 1  and the radius H 2 , and the like, may differ depending on the user, the first compression pad  210  and the second compression pad  220  may not accurately compress intended points of some users. 
     Accordingly, the user is allowed to adjust the positions of the first compression pad  210  and the second compression pad  220  to be suitable to him or her by moving the first compression pad  210  and the second compression pad  220 . In this manner, the user can locate the first compression pad  210  and the second compression pad  220  at correct positions, thereby correctly compress the area of the ulna H 1  and the area of the radius H 2 . 
     To move the positions of the first compression pad  210  and the second compression pad  220 , each of the surfaces of the first compression pad  210  and the second compression pad  220 , in contact with the first compression member  110  and the second compression member  120 , may be provided with an insertion protrusion  230 . The insertion protrusions  230  may be inserted into the internal space of each of the first compression member  110  and the second compression member  120 . In addition, each of the first compression member  110  and the second compression member  120  is provided with a pad receptacle  101 , into which the insertion protrusion  230  is movably inserted. A movement guide  102  is provided in the internal space of the pad receptacle  101 , such that the insertion protrusion  230  may be moved by external force while being engaged with movement guide  102 . Here, an open portion  103  may be provided in the inner side of each of the first compression member  110  and the second compression member  120  to extend in the longitudinal direction, such that the insertion protrusion  230  of each of the first compression pad  210  and the second compression pad  220  is inserted through the open portion  103 . The insertion protrusion  230  may be inserted into the pad receptacle  101  through the open portion  103  to be accommodated in the pad receptacle  101 , and may move the longitudinal direction along the movement. guide  102  disposed within the pad receptacle  101 . Concave-convex portions may be provided on peripheral portions of the movement guide  102 , and the insertion protrusion  230  may be moved by external force in a stepwise manner while being engaged with the concave-convex portions. 
     According to the above-described configuration, in a case in which the user has the wrist protecting band attached to the wrist H, the user can adjust the positions of the first compression pad  210  and the second compression pad  220  by pushing or pulling the first compression pad  210  and the second compression pad  220  in the longitudinal direction, thereby accurately compressing the ulna area and the radius area. 
       FIG. 8  schematically illustrates a coupling structure for auxiliary compression pads of the wrist protecting band according to embodiments of the present disclosure. 
     As illustrated in  FIG. 8 , the first compression pad  210  and the second compression pad  220  according to embodiments of the present disclosure may further include auxiliary compression pads  250 . 
     The auxiliary compression pads  250  may be configured such that the auxiliary compression pads  250  are detachably coupled to the surfaces of the first compression pad  210  and the second compression pad  220 , the surfaces being supposed to be in contact with the wrist H. The auxiliary compression pads  250  are configured to be coupled to the surfaces of the first compression pad  210  and the second compression pad  220 , the surfaces being supposed to be in contact with the wrist H, such that the auxiliary compression pads  250  substantially compress the area of the ulna H 1  and the area of the radius H 2  of the wrist H. The auxiliary compression pads  250  may be made of a soft material, such as leather or silicone. 
     It is possible to adjust the thicknesses of the first compression pad  210  and the second compression pad  220  by coupling or decoupling the auxiliary compression pads  250  to or from the first compression pad  210  and the second compression pad  220 . That is, coupling the auxiliary compression pads  250  to the first compression pad  210  and the second compression pad  220  increases the overall thicknesses of the first compression pad  210  and the second compression pad  220 , while decoupling the auxiliary compression pads  250  from the first compression pad  210  and the second compression pad  220  reduces the overall thicknesses of the first compression pad  210  and the second compression pad  220 . 
     As described above, it is possible to adjust the overall thicknesses of the first compression pad  210  and the second compression pad  220  using the auxiliary compression pads  250 . Accordingly, the user can adjust the thicknesses of the first compression pad  210  and the second compression pad  220  depending on the body conditions of the user or the environmental conditions. 
     Here, the surfaces of the first compression pad  210  and the second compression pad  220 , to be in contact with the wrist H, may have fitting holes  240 . A fitting protrusion  251  may be provided on one surface of each of the auxiliary compression pads  250  so as to be fitted into the fitting holes  240 . In response to the coupling of the fitting protrusions  251  and the fitting holes  240 , the auxiliary compression pads  250  may be detachably coupled to the first compression pad  210  and the second compression pad  220 . 
     In addition, it is possible to adjust the positions of the portions substantially compressing the ulna area and the radius area by adjusting the locations to which the auxiliary compression pads  250  are coupled. In this regard, the plurality of coupling holes  240  may be provided each of the first compression pad  210  and the second compression pad  220  in the longitudinal direction. 
     That is, it is possible to adjust the coupling positions of the auxiliary compression pads  250  by may selectively coupling the fitting protrusion  251  of each of the auxiliary compression pads  250  to one of the plurality of coupling holes  240  in each of the first compression pad  210  and the second compression pad  220 , as illustrated in  FIG. 8 . This structure makes it possible to conveniently adjust the locations of the wrist H to be compressed by the auxiliary compression pads  250 .
