Description
BACKGROUND OF THE INVENTION
The invention relates to an improved massage bed structure and, more particularly, to a portable massage bed that permits adjustment of inclination of a mattress, and that is foldable into a compact case to facilitate transport and storage.
Massaging is growing popular because it helps relax body muscles and promote blood circulate. Conventional massage beds are generally provided with some folding mechanism. However, even though some massage beds are foldable, they are still large in size, which is inconvenient to carry around. It would be desirable to have a massage bed that is foldable into a compact size to enable a masseur to carry the massage bed around with relative ease.
SUMMARY OF THE INVENTION
Therefore, an object of the present invention is to provide an improved massage bed structure, more particularly a massage bed that permits easy adjustment of a back pad and the angle of inclination of a waist and hip pad to provide an ergonomic design so that the user can lie comfortably on the bed during a massage and to help the user to relax his/her muscles during the massage to thereby enhance massaging effects. Another object is to provide a massage bed which is foldable into a compact case to facilitate transport and storage.
Accordingly, the massage bed of the invention includes a bed frame, a mattress, an inclination adjusting structure and a height adjusting structure. The bed frame has a mattress disposed thereon. One end of the mattress is provided with a pillow. The bed frame and the mattress are locked relative to each other by means of the inclination adjusting structure and the height adjusting structure.

Referring to
FIG. 6
, which illustrates operation of the present invention, the pillow
25
allows the user to rest his/her head thereon, the adjusting assembly
254
thereof also allows the user to make suitable adjustment so that the user can relax the head muscles to thereby enhance the massaging effect. When the handle
2542
of the adjusting assembly
254
is pulled outwardly (in the direction of the arrow shown in FIG.
2
), the indexing blocks
2541
of the adjusting assembly
254
can be released. The user can adjust the inclination of the pillow structure

. When the user wants to adjust the inclination of the back pad
21
, it is only necessary to move the back pad
21
upwardly (in the direction of the arrows) to cause the retaining member
422
to slightly disengage from the toothed groove
411
and to adjust the inclination of the back pad
21
at the same time. After adjustment, the retaining member
422
once again engages the toothed groove
411
(after change of inclination of the back pad) for securing purposes. By virtue of the spring
421
that abuts against the retaining member
422
, the stability of the structure can be enhanced. As one end of the bed pad
21
is locked to the securing plate
112
of the first frame
11
by hinge a, during inclination adjustment of the back pad
21
, the back pad
21
can displace up and down with the hinge a between the back pad
21
and the securing plate
112
of the first frame
11
as center.
Referring to
FIG. 8
, which illustrates the operation of the waist and hip height adjusting structure
5
, when the user wants to adjust the waist and hip pad
22
, the lock pin
52
can be pulled outwardly, so that the distal end of the lock pin
52
moves away from the limiting hole
531
in the supporting bar
53
. The user can select one of the high and low limiting holes
531
and thereafter release the lock pin
531
so that the lock pin
531
engages the selected limiting hole
531
. As one end of the waist and hip pad
22
is locked to the pivotal edge
114
of the first frame
11
by hinge a, during inclination adjustment of the waist and hip pad
22
, the waist and hip pad
22
will displace up and down with the hinge a between the waist and hip pad
22
and the pivotal edge
114
of the first frame
11
as center.
Referring to
FIG. 9
, which illustrates displacement of the mattress structure of the invention, the angle of inclination of both the back pad
21
and the waist and hip pad
22
can be adjusted upwardly. The positioning handle
241
at the bottom portion of the foot pad
24
can be released to allow the foot pad
24
to be pulled outwardly to provide flexible adjustment to adapt to users of different heights.
Reference is further made to
FIGS. 10 and 11
, which illustrates the massage bed in a folded state. The present invention is directed to providing a foldable massage bed A that can be folded into a case to enable a masseur to carry the massage bed A out to attend to senile people or people who are paralyzed after suffering stroke, etc. To fold the massage bed structure A, the massage bed is turned sidewise, with the projection p provided at one side of the second frame
12
of the massage bed A to support the bed body. The securing pins
131
,
141
of the left and right leg frames
13
,
14
are pulled out to disengage the support rods
16
from the left and right leg frames
13
,
14
. The support rods
16
are respectively disposed at the bottom portion of the first and second frames
11
