Description

Description CHAIR FOR HANDICAPPED PERSON

Technical Field

[1] The present invention relates to chairs for handicapped persons.

[2] More particularly, the present invention relates to a chair for a handicapped person which is constructed such that the handicapped user can more easily sit on the chair and a chair back or a footrest can be adjusted in orientation or position and be reliably maintained in the adjusted state, thus providing superior sitting comfort to the handicapped user who sits on the chair. Background Art

[3] Generally, a chair basically includes a seat which is maintained in a horizontal state at a predetermined height above the ground to support a user who sits thereon, and a chair back which is provided upright on the rear portion of the seat to support the back of the user who is sitting on the seat. Furthermore, a plurality of supports having predetermined lengths is coupled to the seat to maintain the seat at a predetermined height off the ground. As is well-known in the art, to enhance sitting comfort, armrests may be provided on left and right sides of the seat, and a neck support may be provided on the upper end of the rear surface of the chair back.

[4] According to the material, such a chair is classified into various kinds of chairs, for example, a steel chair, a plastic chair, a wooden chair, etc. Particularly, in consideration of the weight, durability and external appearance of a chair, wooden chairs have been widely used.

[5] From among the typical constructions of the chairs, several chairs for handicapped persons having various structures have been proposed in consideration of several body conditions of the handicapped persons who have a physical impairment that limits the manner of walking or who cannot maintain some special kind of posture.

[6] Particularly, a wheelchair for handicapped persons who have difficulty walking is a representative example of a chair for handicapped persons. As an improved model of the wheelchair, there is an electric wheelchair which is moved in an electric-powered manner and which is controlled by a user manipulating it using buttons or a lever.

[7] However, the meaning of 'wheelchair' is focused on that of a moving unit for handicapped persons rather than a chair for handicapped persons. Hence, it is difficult to conclude that the wheelchair is a type of chair which is to be used indoors by a handicapped person.

[8] In addition to the wheelchair, there are several examples of chairs which are used indoors, for example, in hospitals, for handicapped persons. However, most of the con- ventional chairs have a basic structure such that a small table panel is provided on the front of a chair body, or the height of a seat or the inclination of a chair back is adjusted by an electric-powered method. Disclosure of Invention

Technical Problem

[9] As described above, in the conventional chairs for handicapped persons, the wheelchair is used as a means for moving rather than as a chair, so that it cannot be regarded as a chair for handicapped persons which is to be used just indoors.

[10] Furthermore, in the case of the structure in which the small table panel is provided on the front of the chair body and/or the height of the seat or the inclination of the chair back are adjusted by an electric-powered method, the only advantages added to the general construction of the chair are that a handicapped user can adjust the height of the seat or the inclination of the chair back. In other words, there is a limitation in varying orientation or inclination of the elements of the chair depending on various body conditions of handicapped users, so that superior sitting comfort cannot be ensured.

[11] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a chair for a handicapped person which is constructed such that the handicapped user can more easily sit on the chair and elements thereof can be adjusted in orientation or position and be reliably maintained in the adjusted state, thus providing superior sitting comfort to the handicapped user who sits on the chair.

Best Mode for Carrying out the Invention [38] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings. [39] FIG. 1 is a perspective view illustrating a chair for a handicapped person, according to the present invention. FIG. 2 is a front view of the chair according to the present invention. FIG. 3 is a rear perspective view of the chair according to the present invention. [40] As shown in the drawings, the chair according to the present invention includes a chair main body 10, support frames 20 and a footrest unit 30. In the drawings, although the chair is illustrated as being made of wood, cushions covered with fabric or leather may be provided on a seat 11 and chair back 12 of the chair main body 10, a neck support 50 and armrests 60, in particular, on portions in direct contact with a user's body. In this embodiment, the cushions will be omitted to more clearly explain the basic framework of the chair of the present invention. [41] The chair main body 10 includes the seat 11, the chair back 12 and coupling panels

13. [42] The seat 11 and the chair back 12 are disposed at basic positions in the same manner as in the construction of a general chair. In other words, the seat 11 is horizontally provided at a predetermined height above the ground, and the chair back 12 is placed upright above the rear portion of the seat 11. In this construction, the coupling panels 13 are coupled to left and right sides of the seat 11 and the chair back 12 such that the seat 11 and the chair back 12 are integrated with each other.

[43] The chair main body 10 has a structure capable of adjusting the position and inclination angle of the chair back 12 in the state in which the user sits on the chair. This structure includes extension panels 41, a chair back position adjustment unit 42 and a chair back inclination adjustment unit 43.

[44] The extension panels 41 extend from left and right sides of the chair back 12, particularly, such that the extension panels 41 face the coupling panels 13.

[45] The chair back position adjustment unit 42 includes chair back fastening units Pl which pass through the extension panels 41 and are coupled to the coupling panels 13. Furthermore, the chair back position adjustment unit 42 includes through holes 44 which are formed through the coupling panels 13 at positions ahead of and behind points at which the chair back fastening units Pl are coupled to the coupling panels 13. In the chair back position adjustment unit 42 having the above-mentioned structure, each chair back fastening unit Pl is tightened into one of the through holes 44 after passing through the corresponding extension panel 41, thus adjusting the position of the chair back 12. Here, the through holes 44 may comprise slots which extend predetermined lengths in the longitudinal direction, that is, forwards and backwards.

[46] The inclination adjustment unit 43 is constructed such that in the state in which the chair back fastening units Pl pass through the upper and lower portions of the both extension panels 41 and are coupled to the coupling panel 13, the lower chair back fastening units P2 functions as hinge shafts, around which the upper portions of the extension panels 41 are rotatable at predetermined angles. Here, a curved slot 45 having a radius of curvature corresponding to the rotating radius of the chair back 12 is formed through each extension panel 41 at a position at which the upper chair back fastening unit Pl passes through the extension panel 41. Thus, an angular range of the rotation of the chair back 12 is defined by the curved slots 45.

[47] The chair main body 10 includes the neck support 50 which is coupled to the upper end of the rear surface of the chair back 12. Here, the neck support 50 is coupled to the chair back 12 such that the height thereof is adjustable with respect to the chair back 12. For this, longitudinal slots 51 which extend in the vertical direction are formed through the neck support 50. Neck support fastening units P3 pass through the longitudinal slots 51 and are coupled to the chair back 12.

[48] The support frames 20 are respectively provided on left and right sides of the chair main body 10. The support frames 20 serve to support the chair main body 10 at a predetermined height from the ground. Furthermore, the support frames 20 are hinged at the upper portions thereof to the coupling panels 13 such that the chair main body 10 is rotatable with the support frames 20. Main body fastening units P4 are coupled to the support frames 20 at positions spaced apart from the hinged points at which the support frames 20 are hinged to the coupling panels 13, so that the chair main body 10 can be maintained in a state of being rotated around the hinged points.

[49] Here, the main body fastening units P4 pass through the support frames 20 and are coupled to the chair main body 10. A curved slot 21 having a radius of curvature corresponding to the rotating radius of the chair main body 10 is formed through each support frame 20 at a position at which the main body fastening unit P4 passes through the support frame 20. Thus, an angular range of the rotation of the chair main body 10 around the hinged points is defined by the curved slots 21.

[50] Furthermore, the armrests 60 are coupled to the upper ends of the outer surfaces of the support frames 20 so that the user can put his/her arms on the armrests 60. Here, the armrests 60 are coupled to the support frames 20 so as to be adjustable in height. For this, a longitudinal slot 61 which extends a predetermined length in a vertical direction is formed through each armrest 60, and an armrest fastening unit P5 passes through the longitudinal slot 61 and is coupled to the corresponding support frame 20.

[51] Moreover, a base plate may be mounted at both ends thereof to the lower ends of the support frames 20 to integrate the support frames 20 with each other, but this is not shown in the drawings. Particularly, as a means for moving the chair, wheels, such as casters, may be provided under the base plate.

[52] FIG. 4 is a front perspective view showing the footrest unit 30 of the chair according to the present invention. FIG. 5 is a front view of the footrest unit 30 according to the present invention. FIG. 6 is a rear view of the chair according to the present invention.

[53] Referring to the drawings, the footrest unit 30 is provided below the front end of the seat 11 of the chair main body 10 and is coupled at both ends thereof to the coupling panels 13. The footrest unit 30 includes a footrest 71, connection panels 72 and a footrest adjustment unit 80.

[54] The footrest 71 is disposed below the front end of the seat 11. Preferably, the footrest

71 has a planar shape to allow the user to put his/her feet thereon. The connection panels 72 are coupled to left and right sides of the footrest 71 and the inner surfaces of the coupling panels 13, thus connecting the footrest 71 to the coupling panels 13. The footrest adjustment unit 80 connects the connection panels 72 to the coupling panels 13 and connects the footrest 71 to the connection panels 72 such that the angle, height and posture of the footrest 71 can be adjusted.

[55] The footrest adjustment unit 80 includes a footrest inclination adjustment unit 81, a footrest height adjustment unit 82 and a footrest position adjustment unit 83.

[56] The footrest inclination adjustment unit 81 is constructed such that the upper ends of the connection panels 72 are hinged to the coupling panels 13, and connection panel fastening units P6 pass through the connection panels 72 at positions spaced apart from the hinged points and are coupled to the coupling panels 13. Here, a curved slot 84 having a radius of curvature corresponding to the rotating radius of the connection panel 72 is formed through each connection panel 72 at a position at which the connection panel fastening unit P6 passes through the connection panel 72. Thus, an angular range of the rotation of the connection panels 72 is defined by the curved slots 84.

[57] In the footrest height adjustment unit 82, the footrest 71 is divided into a mounting panel 85 and a support panel 86, and the support panel 86 is coupled to the mounting panel 85 so as to be movable upwards and downwards. For this, longitudinal slots 87 which extend predetermined lengths in the vertical direction are formed through the mounting panel 85, thus defining a range of vertical movement of the support panel 86. In addition, support panel fastening units P7 are coupled to the support panel 86 via the longitudinal slots 87. Here, both ends of the mounting panel 85 are supported by the connection panels 72 such that the footrest 71 can be disposed at the correct position.

[58] In the footrest position adjustment unit 83, two footrest panels 88 onto which the feet of the user are put are provided on the upper surface of the support panel 86. The footrest panels 88 are coupled to the support panel 86 by footrest panel fastening units P8 so as to be adjustable in position with respect to the support panel 86. Here, the footrest panel fastening units P8 pass through the support panel 86 and are coupled to the footrest panels 88. In addition, a longitudinal slot 89 which extends a predetermined length in the lateral direction of the chair is formed through the support panel 86 at a position at which the footrest panel fastening units P8 pass through the support panel 86, thus defining a range within which the footrest panels 88 are adjustable in position with respect to the lateral direction of the chair.

[59] Moreover, the footrest position adjustment unit 83 is constructed such that the footrest panels 88 are movable forwards and backwards. For this, a longitudinal slot 88a which extends a predetermined length forwards and backwards is formed through each footrest panel 88 at a position at which the corresponding footrest panel fastening unit P8 is coupled to the footrest panel 88, thus defining a range within which the footrest panel 88 is movable forwards or backwards.

[60] In the above-mentioned construction, each of the fastening units Pl through P8 has a structure in which a knob is fastened to an end of a screw rod. The coupling of each of the fastening units Pl through P8 to the corresponding element means that it is tightened to the element by a threaded coupling method. Furthermore, because of the threaded coupling, each of the fastening units Pl through P8 can be loosened from the corresponding element, and be tightened again to maintain the element fixed at a desired position after it moves along the corresponding slot.

[61] The operation of the chair having the above-mentioned construction to adjust the angle and position of the chair main body will be explained below.

[62] In the chair of the present invention, the angle of the chair main body 10 with respect to the support frames 20 can be adjusted by rotating the chair main body 10 around the hinged points, at which it is hinged to the support frames 20. Furthermore, the chair back 12 can be moved forwards or backwards with respect to the support frames 20. In addition, the inclination angle of the chair back 12 can be adjusted by rotating the upper portion of the chair back 12 around the lower chair back fastening unit P2 forwards or backwards.

[63] Thanks to the above operation of the chair, the handicapped user can lean his/her body in the chair in a posture suitable for his/her body condition, thus being more comfortable.

[64] Furthermore, in the footrest unit 30, the footrest 71 can rotate forwards or backwards around the hinged points at which the connection panels 72 are hinged to the support frames 20. Thus, when it is desired for the handicapped user to sit on the chair or stand up therefrom, the footrest unit 30 can be rotated inwards, so that the user can conveniently conduct the desired motion.

[65] In addition, the position of the support panel 86 is adjustable upwards or downwards on the mounting panel 85. The positions of the footrest panels 88 are adjustable leftwards or rightwards on the support panel 86. Hence, the handicapped user can more comfortably maintain the posture of his/her legs.

[66] As well, in the chair of the present invention, the heights of the armrests 60 and the neck support 50 are adjustable, thus providing superior sitting comfort to the handicapped user.
