DETAILED DESCRIPTION OF THE INVENTION
[0024] Referring to the drawings and initially to FIGS. 2-5, a
combination type bath chair in accordance with a preferred
embodiment of the present invention comprises a seat 5 having a
rear side provided with a backrest 6 which is fixed by two backrest
support racks 61. The seat 5 has a bottom face provided with
multiple chair legs 8. Each of the chair legs 8 is provided with a
retractable tube 81, and has a lower end provided with a snapping
member "B" which has a positioning stub protruded outward from a
through hole 84 formed in each of the chair legs 8. Each of the
retractable tubes 81 is formed with multiple positioning holes 810,
so that each of the retractable tubes 81 may be retracted on each
of the chair legs 8 freely, thereby adjusting the length of the
chair legs 8, so as to adjust the height of the bath chair.
[0025] The bottom face of the seat 5 is secured with backrest
connecting tubes 62 and chair leg connecting tubes 7. Each backrest
connecting tube 62 has a distal end formed with an elongated hole
65 and secured with an urging sleeve "A", and each chair leg
connecting tube 7 has a distal end formed with an elongated hole 71
and secured with an urging sleeve "A". The urging sleeve "A" has a
port formed with a conic oblique opening "A1" as shown in FIGS. 4
and 5.
[0026] Each of the backrest support racks 61 has a distal end
provided with an insertion end 63 that may be inserted into the
backrest connecting tube 62. Each of the chair legs 8 has an upper
end provided with an insertion end 82 that may be inserted into the
chair leg connecting tube 7. Each of the insertion ends 63 and 82
is provided with a snapping member "B" which has a positioning stub
protruded outward from a through hole 80 formed in each of the
insertion ends 63 and 82. The insertion end 63 is provided with a
conic portion 64, and the insertion end 82 is provided with a conic
portion 83.
[0027] Thus, by the snapping member "B" mounted in each of the
backrest support racks 61 and each of the chair legs 8, when the
insertion end 63 of each of the backrest support racks 61 is
inserted into the backrest connecting tube 62, and the insertion
end 82 of each of the chair legs 8 is inserted into the chair leg
connecting tube 7, the snapping member "B" may be snapped into the
elongated holes 65 and 71.
[0028] Thus, the backrest support racks 61 and the chair legs 8 may
be assembled, dismantled and packaged easily, thereby shortening
the volume of package.
[0029] The user may slightly exert a pressure on the backrest
support racks 61 and the chair legs 8, so that the snapping member
"B" mounted in each of the backrest support racks 61 and each of
the chair legs 8 may be snapped into the elongated hole 65 and 71
of the backrest connecting tube 62 and the chair leg connecting
tube 7 by the elastic action of the urging sleeve "A".
[0030] Thus, when each of the backrest support racks 61 and each of
the chair legs 8 is inserted into the backrest connecting tube 62
and the chair leg connecting tube 7, the urging sleeve "A" may
provide an efficient urging effect.
[0031] In addition, the conic portion 64 and 83 of the insertion
end 63 and 82 of each of the backrest support racks 61 and each of
the chair legs 8 is urged on the conic oblique opening "A1" of the
urging sleeve "A" of the backrest connecting tube 62 and the chair
leg connecting tube 7. Thus, when the user is seated on the seat 5,
each of the chair legs 8 is pressed by the user's weight, so that
the conic portion 83 of the insertion end 82 of each of the chair
legs 8 is urged on the conic oblique opening "A1" of the urging
sleeve "A" of the chair leg connecting tube 7, thereby increasing
the rigidity and stability of each of the chair legs 8.
[0032] As shown in FIGS. 3 and 6, the seat 5 has two sides each
formed with an elongated slot 51 each provided with a substantially
L-shaped handrail 9 which has a lower side 91 secured on the bottom
face of the seat 5, and a vertical side 92 protruded outward from
the elongated slot 51.
[0033] When the user exerts a force "F" on the handrail 9, the
lower side 91 and the vertical side 92 of the handrail 9 are
stopped by the bottom face of the seat 5 and the wall of the
elongated slot 51 respectively, thereby providing a reaction force
"CF1" and "CF2" to counteract the force "F". The handrail 9 may be
provided with a soft pad, thereby enhancing the safety of use.
[0034] Although the invention has been explained in relation to its
preferred embodiment as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
cover such modifications and variations that fall within the true
scope of the invention.
