## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a composite chair storage device and, more particularly, to the storage device capable of turning an exercise module upside down to facilitate its storage into a containing space of a chair.
2. Description of the Prior Art
In general, conventional massage sofas emphasize the functions of massage and leg rest storage, and a complicated structure with link rods and an additional power supply are required to achieve the effect of storing the leg rest.
However, the aforementioned conventional massage sofa has the following drawbacks:
1. The conventional massage sofa only provides a simple massage function, and thus having a limited scope of applicability and a low commercial value.
2. The conventional massage sofa requires an additional power supply, and thus is not compliant with the energy saving and carbon reduction requirements.
Even though the aforementioned conventional massage sofa can meet the basic functional requirements of providing simulated massages and leg rests, it cannot meet the environmental protection and durability requirements due to its complicated structure and components and an additionally required power supply and fails to improve the industrial effects or to serve as a widely-used composite chair storage device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustration only, the preferred embodiments in accordance with the present invention.
With reference to FIGS. 1 and 3, a composite chair storage device of the present invention comprises a chair 1, a slide mechanism 2 and an exercise module 3.
The chair 1 has a containing space 11.
The slide mechanism 2 is installed in the containing space 11 of the chair 1, and includes a main rod 21, a first transverse rod 22, a second transverse rod 23 and two slide rails 24. The first transverse rod 22 and the second transverse rod 23 are installed perpendicularly to the main rod 21. A first roller 221 and a second roller 231 are installed on both sides of the first transverse rod 22 and the second transverse rod 23 respectively, and the first roller 221 and second roller 231 are embedded into the slide rails 24 for performing linear displacement.
The exercise module 3 can be selectively folded into the containing space 11 and unfolded from the containing space 11. The exercise module 3 includes a sleeve rod 31, an exercise equipment 32 and a pressure element 33. The sleeve rod 31 is sheathed on the main rod 21 of the slide mechanism 2, and both sides of the pressure element 33 (as shown in FIG. 5) are respectively and pivotally installed to the sleeve rod 31 and the exercise equipment 32.
The sleeve rod 31 of the exercise module 3 further includes two third rollers 311. The exercise equipment 32 further includes a support-rod base 321. The exercise equipment 32 is a fitness bicycle or a weight training device, and the pressure element 33 is a hydraulic cylinder or a pneumatic cylinder.
The exercise module 3 is disposed in the containing space 11 of the chair as shown in the figure, and the exercise module 3 also can use the third roller 311 and the support-rod base 321 as the main support structures. The first roller 221 and the second roller 231 are embedded into the slide rails 24 respectively to constitute a secondary support structure. In a horizontal unfolded status as shown in FIG. 5, the pressure element 33 (which is a hydraulic cylinder or a pneumatic cylinder) is situated at the maximum compressed stroke to further provide additional stability of the exercise module 3.
With reference to FIGS. 1, 3 and 6, when the exercise equipment 32 of the exercise module 3 is not in use, and when the exercise equipment 32 is stored as shown in FIGS. 2 and 4, it is necessary to turn the exercise module 3 upside down to set the exercise module in a folded status (as shown in FIG. 6) before the exercise module 3 can be stored into the containing space 11 of the chair 1 (as shown in FIG. 1). In the process of turning the exercise module 3 upside down and folding the exercise module 3, the pivoting position of the pressure element 33 and the sleeve rod 31 is used as a hinge to turn the exercise module 3 upward. Then, the exercise module 3 is turned to an angle approximately equal to 90 degrees, so that the exercise module 3 is attached onto the sleeve rod 31 to obtain the minimum height, the support-rod base 321 leaves the ground, and only the third roller 311 is in contact with the ground. Now, the pressure element 33 (which is a hydraulic cylinder or a pneumatic cylinder) is situated at the maximum stretching stroke condition to further provide additional stability of supporting the exercise module 3.
When the exercise module 3 is pushed to move towards the containing space 11 of the chair 1, the first roller 221 and the second roller 231 are embedded into the slide rails 24 to allow a slide movement. Thus, the exercise module 3 can enter into the containing space 11 of chair 1 completely with the assistance of the sliding third roller 311, to achieve the storing effect as shown in FIGS. 2 and 4. The stored exercise module 3 is completely hidden into the containing space 11 of the chair 1 to become a whole piece with the chair 1. Thus, the invention provides both functional and aesthetic effects.
If it is necessary to use the exercise module 3 again, the steps of the aforementioned procedure are reversed. In other words, the exercise module 3 is pulled out to a fixed position from the containing space 11 of the chair 1 as shown in FIG. 6, and then turned downward to an angle approximately equal to 90 degrees. Thus, the third roller 311 and the support-rod base 321 are in contact with the ground stably. Now, the unfolding is completed as shown in FIG. 5.
In summation of the description above, the present invention provides a composite chair storage device comprising the chair 1, the slide mechanism 2 and the exercise module 3 for storing a composite chair. The first roller 221 and the second roller 231 are embedded into the slide rails 24 for performing a linear displacement. With the assistance of the sliding third roller 311 and the pressure element 33 capable of turning over the exercise equipment 32 of the exercise module 3, the exercise module 3 can be stored into the containing space 11 of the chair 1 or unfolded from the containing space 11 of the chair 1 quickly and conveniently. Therefore, the composite chair can be folded or unfolded effectively.
While various embodiments in accordance with the present invention have been shown and described, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
