MODES OF THE INVENTION

(12) Hereinafter, embodiments that can be easily performed by those skilled in the art will be described in detail with reference to the accompanying drawings. However, embodiments of the present invention may be implemented in several different forms, and are not limited to embodiments described herein. In addition, parts irrelevant to description are omitted in the drawings in order to clearly explain embodiments of the present invention. Similar parts are denoted by similar reference numerals throughout this specification.

(13) FIG. 1 is a perspective view illustrating a cervical brace according to one embodiment of the present invention, and FIG. 2 is a coupling view of a lower support and a support member of the cervical brace according to one embodiment of the present invention.

(14) As illustrated in FIG. 1, a cervical brace 1 may include an upper support 10 covering and supporting a wearer's jaw, a lower support 20 that is pressed against and supported by the shoulders around the wearer's neck, a rear support 30 that is positioned behind the upper and lower supports 10 and 20 and supports the rear of the wearer's neck, and height adjusters 100 that perpendicularly move the upper support 10 to the lower support 20.

(15) The upper support 10 supports the wearer's jaw from below. As the upper support 10 presses and supports the wearer's jaw upward, the neck, that is, the cervical vertebrae, may stand correctly.

(16) As the upper support 10 has a curved shape to match the wearer's jawline and the lower outline thereof, the upper support 10 may be pressed against the wearer's entire jaw, and thus may provide a convenient wearing sensation.

(17) In addition, fixing members 140 to which the height adjusters 100 may be detachably coupled may be installed on both sides of the upper support 10.

(18) The fixing members 140 will be described below in detail with reference to FIG. 10.

(19) The lower support 20 serves as a base that supports the overall cervical brace 1, and may be formed with a curved plate in a shape that covers to fit the curvature of the body by extending along the circumference around the wearer's neck to the front, both shoulders, and a partial rear of the shoulders.

(20) The lower support 20 is put on and pressed against the circumference around the neck when worn, and supports the overall cervical brace 1, and since the rear of the lower support 20 is open, the wearer may easily put on and take off the cervical brace 1.

(21) In addition, support members 22 that support connecting members 130 may be formed on one surface of the lower support 2. Specifically, the support members 22 may be installed at one surface of the lower support 20 corresponding to the height adjusters 100.

(22) Here, the support members 22 may be formed in cylindrical shapes as illustrated in FIG. 2. The connecting members 130 of the height adjusters 100 that will be described below may be fixedly coupled to upper portions of the cylindrical support members 22, or the connecting members 130 may be inserted into the support members 22 to be fixedly coupled thereto.

(23) Meanwhile, a coupling structure of the support members 22 and the lower support 20 is not limited to a configuration described as illustrated in FIG. 2. For example, the coupling structure may be freely configured as long as the support members 22 can fixedly couple the connecting portions 130 to the lower support 20.

(24) The rear support 30 supports the rear of the wearer's neck, and may pair with the upper support 10 to hold the entire circumference of the wearer's neck to be balanced.

(25) The height adjusters 100 will be described below with reference to FIGS. 3 to 11.

(26) FIG. 3 is a perspective view illustrating a height adjuster of the cervical brace according to one embodiment of the present invention, FIG. 4 is an exploded perspective view in FIG. 3, FIG. 5 is an exploded perspective view illustrating a rotating member and a coupling member of the cervical brace according to one embodiment of the present invention, and FIG. 6 is a coupling perspective view in FIG. 5.

(27) As illustrated in FIG. 3, the height adjusters 100 are installed for adjusting a height between the lower support 20 and the upper support 10 so that the cervical brace 1 may fit the wearer's body shape.

(28) The height adjusters 100 may each include a body 110 installed on one side surface of the upper support 10, a rotating member 120 rotatable in both directions and positioned at one side of the body 110, the connecting member 130 fixedly coupled to the support member 22 of the lower support 20 corresponding to the rotating member 120 and installed to penetrate through the rotating member 120.

(29) As illustrated in FIG. 4, an accommodation portion 112 having one open side to accommodate the rotating member 120 may be formed at the body 110.

(30) Specifically, the body 110 may be formed in a “C” shape to be in contact with upper and lower surfaces of the rotating member 120. Specifically, the body 110 has an upper beam protruding from an upper end to one side and a lower beam protruding from a lower end to one side. Accordingly, the accommodating portion 112 is formed between the upper beam and the lower beam.

(31) In addition, a pair of through holes 114 may be formed in the body 110 in contact with the upper and lower surfaces of the rotating member 120. That is, the pair of through holes 114 may be formed at upper and lower portions of the accommodation portion 112 of the body 110. Specifically, a pair of through holes 114 may be formed in the upper beam and the lower beam, respectively.

(32) Meanwhile, although the body 110 is illustrated and described to have a “C” shape, the configuration of the present invention is not limited thereto. For example, the body may be freely formed in any shape as long as a part of the body 110 is opened so that the wearer may rotate the rotating member.

(33) The rotating member 120 is for vertically moving the upper support 10 along the connecting member 130, and may rotate about the connecting member 130 in both directions.

(34) Specifically, as illustrated in FIG. 3, the rotating member 120 may be accommodated in the accommodation portion 112, and may be formed in a cylindrical shape with an upper surface in contact with a lower surface of the upper beam and a lower surface in contact with an upper surface of the lower beam, and may be formed such that one side of a circumferential surface is disposed outside a front end of the upper beam and a front end of the lower beam, and as illustrated in FIG. 5, seating grooves 122 may be formed in the upper and lower surfaces of the rotating member 120. As illustrated in FIG. 3, an upper guide protrusion may protrude from the upper surface of the rotating member 120 in the shape of a ring through which the connecting rod 130 passed through the center. An upper guide groove is recessed in the shape of a ring on the lower surface of the upper beam so that the upper guide protrusion is inserted. A lower guide protrusion may protrude from the lower surface of the rotating member in the shape of a ring through which the connecting rod 130 passed through the center. A lower guide groove is recessed in the shape of a ring on the upper surface of the lower beam so that the lower guide protrusion is inserted.

(35) As illustrated in FIG. 6, coupling members 124 are seated in the pair of seating grooves 122. The pair of seating grooves 122 may be formed in the upper and lower surfaces of the rotating member 120 corresponding to the through holes 114 formed at upper and lower portions of the accommodation portion 112.

(36) In addition, the seating grooves 122 may be formed in a shape corresponding to a shape of the coupling member 124, and a nut may be used as the coupling member 124.

(37) Here, a central through hole 126 through which the connecting member 130 may penetrate may be formed at the center of the seating grooves 122 and the center of the coupling members 124.

(38) The connecting portion 130 in a cylindrical shape may include one end coupled to the support member 22 and formed to extend toward the upper support 10, and include a circumferential surface having a screw thread to be coupled to the coupling member 124.

(39) Here, the connecting member 130 may be formed to have a predetermined length, and specifically, the predetermined length of the connecting member 130 may be greater than a length between a bottom surface of the support member 22 of the lower support 20 and the height adjuster 110 of the upper support 10.

(40) In addition, the connecting member 130 may be installed to penetrate one surface of the lower support 20 corresponding to the rotating member 120 and the rotating member 120.

(41) Specifically, one side of the connecting member 130 may be fixed to an upper portion of the support member 22 installed at one surface of the lower support 20, and the other side of the connecting member 130 may be installed to penetrate the pair of through holes 114 formed in the accommodation portion 112 and the central through hole 126. The rotating member 120 may be penetrated by the connecting rod together with the upper beam and the lower beam so as to rotate in both directions about the axis of the connecting rod 130.

(42) That is, the connecting member 130 coupled to the support member 22 of the lower support 20 may sequentially penetrate the through hole 114 formed in the lower portion of the accommodation portion 112 of the body 110, the central hole 126 of the rotating member 120, and the through hole 114 formed in the upper portion of the accommodation portion 112 of the body 110.

(43) A method of adjusting a height of the upper support 10 having the above-described structure will be simply described as follows. As illustrated in FIG. 3, when a wearer rotates the rotating member 120, the pair of coupling members 124 seated on the upper and lower surfaces of the rotating member 120 may move along the screw thread of the connecting member 130.

(44) Specifically, when the wearer rotates the rotating member 120 rotatable in both directions in one direction (see an arrow A), the coupling members 124 seated in the seating groove 122 of the rotating member 120 may rise along the connecting member 130, and accordingly, the upper support 10 may rise (see an arrow B)

(45) On the other hand, when the rotating member 120 is rotated in the other direction, the coupling members 124 seated in the seating groove 122 of the rotating member 120 may be lowered along the connecting member 130, and accordingly, the upper support 10 may be lowered.

(46) Accordingly, the wearer may adjust a position of the upper support 10 with respect to the lower support 20 to fit his or her jaw.

(47) The body 110 of the height adjuster 100 having the above-described structure may be installed to be detachable from the upper support 10, and the fixing member 140 to which the body 110 is fixedly coupled may be installed at the upper support 10.

(48) Specifically, the above will be described below with reference to FIGS. 7 to 11.

(49) FIG. 7 is a view illustrating an angle adjusting member of the cervical brace according to one embodiment of the present invention, FIG. 8 is an exploded perspective view in FIG. 7, FIG. 9 is a cross-sectional view illustrating a method of operating the angle adjusting member shown in FIG. 8, FIG. 10 is a perspective view illustrating a fixing member of the cervical brace according to one embodiment of the present invention, and FIG. 11 is a view illustrating a state in which the angle adjusting member is inserted into the fixing member of the cervical brace according to one embodiment of the present invention.

(50) As illustrated in FIG. 7, an angle adjusting member 150 configured to adjust an angle of the upper support 10 to the wearer's jaw may be detachably installed at the other side of the body 110.

(51) The angle adjusting member 150 may have a trapezoidal cross-section, and be screwed to the other side of the body 110.

(52) That is, the angle adjusting member 150 may be formed so that the cross-sectional area thereof gradually increases from one surface of the angle adjusting member 150 toward the outside.

(53) Specifically, as illustrated in FIG. 8, a hole 154 through which a screw 152 may penetrate may be formed in the angle adjusting member 150, and a coupling groove 116 into which a screw of thread of the screw 152 is inserted and coupled may be formed at the other side of the body 110 corresponding to the hole 154.

(54) As illustrated in FIG. 9, the angle adjusting member 150 may be inclined at a rotation angle θ by being rotated about the horizontal line L perpendicular to the direction of gravity.

(55) In addition, the angle adjusting member 150 may be pressed against and fixed to the body 110 in a state in which the angle adjusting member 150 is inclined at a rotation angle.

(56) In addition, as illustrated in FIG. 10, the angle adjusting member 150 inclined at a rotation angle may slide and be fixed to the fixing member 140 installed at the upper support 10.

(57) Here, a guide groove 142 in a shape corresponding to a shape of the angle adjusting member 150 may be formed in the fixing member 140.

(58) That is, the guide groove 142 may be formed to have a trapezoidal cross-section that is the same as that of the angle adjusting member 150.

(59) A method of adjusting an angle of the upper support 10 of the cervical brace 1 having the above-described configuration will be described as follows.

(60) As the wearer loosely inserts the angle adjusting member 150 into the coupling groove 116 of the other side of the body 110 using the screw 152, the angle adjusting member 150 may be temporarily fixed to the body 110.

(61) Here, as illustrated in FIG. 9, the angle adjusting member 150 may rotate about the horizontal line L perpendicular to the direction of gravity.

(62) Therefore, after rotating the angle adjusting member 150, the wearer may press and fix the angle adjusting member 150 inclined at a predetermined rotation angle against and to the other side of the body 110 through the screw 152.

(63) Finally, as illustrated in FIG. 11, the angle adjusting member 150 may be fixed by being inserted into the guide groove 142 of the fixing member 140, and accordingly, an angle of the upper support 10 may be adjusted to fit the wearer's body shape through the angle adjusting member 150.

(64) Here, the fixing member 140 may be installed at the upper support 10 parallel to the horizontal line L. As the angle adjusting member 150 inserted into the guide groove 142 of the fixing member 140 is fixed to the body 110 in a state in which the angle adjusting member 150 is inclined with respect to the horizontal line L, the body 110 is inclined at a rotation angle θ of the angle adjusting member 150.

(65) In addition, since the body 110 is inserted into the guide groove 142 of the fixing member 140 in a state in which the body 110 is inclined at a rotation angle θ, the upper support 10 may also be inclined at the rotation angle θ of the angle adjusting member 150.

(66) Accordingly, since a position of the upper support 10 may fit the wearer's body shape, the wearing sensation of the cervical brace 1 may be improved.

(67) In the cervical brace 1 according to the present invention, since the body 110 and the angle adjusting member 150 of the height adjuster 100 are detachable from each other, a height of the upper support 10 may also be adjusted through the rotating member 120 and the connecting member 140 after an angle of the upper support 10 is adjusted through the angle adjusting member 150.

(68) Accordingly, as the height adjusting member connected to the lower support to adjust a height of the upper support and the angle adjusting member are provided at the one side of the upper support supporting the wearer's jaw, the height and angle of the upper support may be easily adjusted to fit the wearer's body shape. Therefore, the wearing sensation the can be improved.

(69) In addition, since the coupling member of the height adjuster is formed in a nut shape, and the connecting member is formed to have the screw thread formed on the circumferential surface to be coupled to the coupling member, the number of parts may be dramatically decreased. Therefore, the manufacturing and assembly cost of products can be decreased.

(70) In addition, since the coupling member of the height adjuster is formed in a nut shape, and the connecting member is formed to have the screw thread formed on the circumferential surface to be coupled to the coupling member, the abrasion phenomena can be prevented.

(71) While embodiments of the present invention have been described above, the scope of the present invention is not limited thereto. Other embodiments may easily be made by those understanding the scope of the present invention and skilled in the art by addition, change, deletion, and the like of components, and these are also included in the range of the scope of the present invention.
