Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bullet armor for a chair used, for example, in a seat or backrest of an office swivel chair.

[0002]

[Prior Art]

 As shown in FIG. 6, a chair shell used conventionally has a cushion body (52) attached to the front of a hard back support plate (51) and an exterior material (53). It was attached so as to cover the front of the cushion body (52) and be wrapped around the back side of the back support plate (51).

[0003] Then, the manufacturing is to superimpose the back support plate (51) and the cushion body (52) in an appropriately arranged state, and to bond them, and then to bond the exterior material. It was

[0004]

[Problems to be solved by the device]

 However, when the back support plate (51) and the cushion body (52) are overlapped with each other, the two do not engage with each other in the overlapped state, and thus the relative positions are likely to be displaced, Therefore, it takes time and effort to superimpose them in a proper arrangement state, and there is a drawback in that the manufacturing efficiency of the ammunition is deteriorated.

The present invention has been made in view of such drawbacks of the related art, and an object of the invention is to provide a chair shell which can be efficiently manufactured.

[0006]

[Means for Solving the Problems]

 For the above-mentioned purpose, the invention is such that a rising edge portion that rises to the front side is provided on the peripheral edge of a hard rear support plate, and a fitting edge that fits on the rising edge portion on the rear peripheral edge portion of the cushion body. A fitting recess is provided, and the cushion body is attached to the front surface of the back support plate with the fitting recess fitted to the rising edge, and the exterior material covers the front surface of the cushion body and the back surface. The gist is a bullet armor for a chair, which is characterized in that it is attached to the back side of the support plate while being rolled up.

[0007]

[Action]

 In the manufacture of the chair shell with the above structure, when the back support plate and the cushion body are overlapped with each other so that the rising edge portion and the fitting recess portion are fitted to each other, there is no misalignment and the proper arrangement state. Becomes

[0008]

【Example】

 Embodiments will be described below with reference to the drawings.

The work swivel chair (1) shown in FIG. 1 has a leg portion (4) having a plurality of radial leg blades (3) each having a caster (2) attached to each tip, and the leg portion (4). A seat (6) rotatably supported at an upper position of (4) via a column (5), and a backrest (6) disposed at a rear portion of the seat (6) via a backrest support rod (7). 8) and.

The ammunition body according to the present invention is used for the seat (6) and the backrest (8), but here, the ammunition body used for the backrest (8) is taken as an example. Describe the configuration.

As shown in FIG. 2, the shell (9) comprises a support substrate (10) made of a hard synthetic resin, and a male and female latching pieces (11) (12) on the upper side. And the male and female screws (13) (14) on the lower side are fastened together to form a backrest (8). In addition, the ammunition body of the present invention also includes one that constitutes a backrest by itself. The same is true for the seat.

As shown in FIG. 3, the ammunition body (9) includes a back support plate (16), a cushion body (17) which is arranged and affixed to the front surface of the back support plate (16) in an overlapping state. The cushioning body (17) is composed of an exterior material (18) attached so as to cover the front surface of the back support plate (16) so as to extend over the peripheral edge of the back surface.

The back support plate (16) is an integrally molded product made of a hard constituent resin, and is molded into a curved shape with a concave front side, and its entire periphery is, as shown in FIG. 4, The rising edge (19) rising to the front side is integrally provided.

The cushion body (17) is made of sponge or the like, its shape follows the front shape of the back support plate (16), and its thickness is the height of the rising edge (19) of the back support plate (16). The backside support plate (16) is so thick that the entire peripheral edge thereof is large enough to protrude outside the periphery of the backside support plate (16) when it is superposed on the backside support plate (16). A loop-shaped fitting recess (20) that fits into the rising edge (19) of the back support plate (16) is provided on the peripheral edge of the back surface of the cushion body (17).

The exterior material (18) is made of cloth, synthetic resin sheet or the like.

With the above-mentioned configuration, the manufacturing operation of the shell (9) can be performed efficiently as follows.

That is, first, as shown in FIG. 4, the back support plate (16) and the cushion body (17) are laminated and attached in a predetermined proper arrangement. This work is performed by fitting the rising edge (19) of the back support plate (16) and the fitting recess (20) of the cushion body (17), and then by sticking the opposing surfaces under pressure. Done. By fitting the rising edge portion (19) and the fitting recessed portion (20), the back support plate (16) and the cushion body (17) can be easily arranged in an appropriate state.

Next, the exterior material (18) is attached. As shown in FIG. 5, this attachment is performed by stacking the exterior material (18) on the cushion body (17) and adhering the cushion body (17) so as to conform to the front shape, and the peripheral edge portion on the back surface of the back support plate (16). It is carried out by wrapping it around and sticking it to the back surface peripheral edge of the back support plate (16).

As described above, with the above structure, the back support plate (16) and the cushion body (17) can be polymerized and adhered with high efficiency, and thus the efficient production of the shell (9) can be realized. Wear.

The rising edge does not necessarily have to be provided on the entire circumference of the back support plate (16), and a plurality of rising edges may be provided at predetermined intervals in the circumferential direction. Further, it goes without saying that the ammunition body of the present invention can be applied to the seat (6) and other armor bodies such as armrests in substantially the same manner.

[0021]

[Effect of the device]

 According to the above description, the chair bullet armor of the present invention is provided with the rising edge portion which rises to the front side on the peripheral edge of the hard rear support plate, and is fitted to the rising edge portion on the rear peripheral edge portion of the cushion body. A fitting recess is provided, and the cushion body is attached to the front surface of the back support plate in a state where the fitting recess is fitted to the rising edge, and the exterior material covers the front surface of the cushion body and the back surface. Since it is attached in a state of being rolled up on the back side of the support plate, the work of attaching the back support plate and the cushion body to each other can be efficiently performed, which in turn makes it possible to efficiently manufacture the shell. it can.
