Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massage chair, and more particularly to a massage chair that is compact and compact during transportation and packaging.

[0002]

2. Description of the Related Art A massage chair used in a general household has a structure in which a seat portion and a backrest portion are inseparably assembled together, and a massage mechanism is housed in the backrest portion.

[0003]

However, the above-mentioned massage chair in which the seat portion and the backrest portion are integrally assembled is heavy and large and bulky, which is disadvantageous for packaging and transportation. Especially, in the case of transportation to foreign countries, there is a problem that the unit price of the product is increased because the transportation cost is high.

In addition to the seat portion and the backrest portion, there is a specification in which a rear fall prevention frame is attached to the lower rear portion of the seat portion for the purpose of safety in use. It was particularly large and bulky because it extended over to the lower rear part of the seat.

An object of the present invention is to provide a massage chair having a seat portion and a backrest portion as described above so that the massage chair can be disassembled so that the entire body can be compactly packed, and transportation and transportation can be facilitated. It is also intended to simplify the assembly.

[0006]

According to the present invention, in a massage chair comprising a seat portion and a backrest portion, the backrest portion is detachably attached to the seat portion.

Further, according to the present invention, in a massage chair comprising a seat portion and a backrest portion, the backrest portion can be detachably attached to the seat portion, and the rear fall prevention frame can be detachably attached to the lower rear portion of the seat portion. It is characterized by being attached.

[0008]

In packaging and transportation, the seat portion and the backrest portion are separated from each other, and the backrest portion is stacked on the seat portion, whereby the whole body can be made bulky and compact.

In the case where the rear fall prevention frame is provided,
By separating and stacking the seat portion, the backrest portion, and the rearward fall prevention frame from each other, it is also possible to keep the entire body compact and compact.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the massage chair according to the present invention will be described with reference to the drawings. In FIG. 1A, this massage chair comprises a seat portion 1 and a backrest portion 2. The seat 1 is
A seat frame 3 formed by assembling pipe materials and the armrests 4 attached to the left and right of the seat frame 3 are entirely covered with an outer skin 5 made of leather or synthetic leather. The backrest portion 2 is formed by covering the entire backrest frame (not shown) with an outer skin 6 made of leather or synthetic leather, and inside thereof, although not shown, a motor and a kneading operation driven by the motor. A massaging mechanism consisting of members and striking members is stored and deployed.

The backrest portion 2 is attached to the seat portion 1 in a freely attachable / detachable manner and with an adjustable tilt angle. As this mounting means, for example, a U-shaped backrest receiving frame 7 is provided on the rear side of the seat frame 3 so as to be swingable back and forth around a pivot 8, and a slide plate 9 is provided inside the seat frame 3 for supporting the backrest. It is installed on the lower side of 7 so as to be movable in the front-back direction. The slide plate 9
The back-and-forth movement operation is performed by, for example, a hydraulic operation cylinder (not shown). Thus, the lower portion of the backrest portion 2 is inserted into the backrest receiving frame 7, the bolt 10 shown in FIG. 1B is passed through the hole 11 of the slide plate 9 from below, and further inserted into the hole 12 of the backrest receiving frame 7. The lower part of the backrest part 2 is seated by screwing it through the screw hole 13 provided in the lower part of the backrest part 2.
It is detachably fixed to. Further, by operating the hydraulic operating cylinder with the reclining operating lever 14 provided below the armrest 4 to move the slide plate 9 back and forth, the backrest 2 can be changed to an arbitrary inclination angle around the pivot 8. .

When packing and transporting the massage chair thus constructed, the bolt 10 is loosened and removed, and the backrest portion 2 is pulled out upward from the backrest receiving frame 7 of the seat portion 1 to separate the two. The backrest 2 is placed on the seat 1. Then, both can be stacked in a low bulk.

At the time of assembly, the lower portion of the backrest portion 2 is inserted into the backrest receiving frame 7 of the seat portion 1, and the lower portion of the backrest portion 2 is fastened and fixed to the backrest receiving frame 7 and the slide plate 9 with bolts 10.

In the above embodiment, the input power source 15 is provided on the seat portion 1 side, and when the input power source 15 is connected to the motor of the massage mechanism in the backrest portion 2, it is shown in FIG.
As shown in (B), a connector 17 is provided at the end of a cord 16 connected to the input power source 15 on the seat 1 side, and a connector 19 is provided at the end of a cord 18 connected to the motor on the backrest 2 side. , Both connectors 17 and 19 are detachably connected. By doing so, the work of separating the seat portion 1 and the backrest portion 2 can be performed safely and easily without breaking the cords 16 and 18. However, when the input power supply 15 is provided on the backrest 2 side, it is not necessary to employ such connecting means.

A rear fall prevention frame 20 is detachably attached to the lower rear portion of the seat 1 so that the massage chair does not inadvertently fall backward when the massage chair is used. The rearward fall prevention frame 20 is, for example, as shown in FIGS. 3 (A) and 3 (B), formed into a U-shape as a whole and has a grounding frame portion 21 and left and right side frames 22. As the attachment means, the tip 22a of the side frame 22 is removably inserted into the left and right frame fixing portions 23 made of pipes fixed to the lower rear portion of the seat portion 1, and then the frame fixing portion 23 and the side frame 22 are attached. Holes 24 respectively provided at the tip 22a
By inserting the insertion / removal pin 25 with a head into the hole, and inserting the snap pin 27 into the hole 26 at the tip of the insertion / removal pin 25 protruding from the hole 24, the rear fall prevention frame 20 is detachably attached to the lower rear part of the seat portion 1. To be

At this time, the snap-in pin 27 is pulled out from the hole 26, the pull-out pin 25 is pulled out from the hole 24, and the tip 22a of the side frame 22 is pulled out rearward from the frame fixing portion 23, whereby the rear fall prevention frame 20 is seated. It can be easily removed from 1. The backward fall prevention frame 20 thus removed is stacked with the backrest portion 2 on the seat portion 1 separated from each other as described above,
The whole is low in bulk and can be compacted, which is convenient for packing and transportation.

[0017]

According to the present invention, since the backrest portion is detachably attached to the seat portion, the both can be separated and can be stacked in a low volume, which is convenient for packaging and transportation, and the separating member. Assembling can be done easily because the number of points is limited to two, the seat and the backrest.

Further, even in the case where the rearward fall prevention frame is detachably provided, the three parts of the seat portion, the backrest portion and the rearward fall prevention frame can be separated from each other and stacked at the time of packaging or transportation. It is convenient because it can be placed in a compact and compact size.
