Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a resin sheet structure which can be mounted at a predetermined position on a floor by fixing a seat leg with a bolt.

[0002]

[Prior art]

 For example, a so-called resin sheet having a seat body integrally formed with a cushion portion and a back portion from a synthetic resin and seat legs attached to the lower surface of the seat body is used in benches and vehicles of various facilities, It is known as a seat for ships.

Such a resin sheet is, for example, arranged at a predetermined position on a floor surface such as a vehicle floor, and is attached by fixing a seat leg to the floor surface by bolting at the position. .

[0004]

[Problems to be solved by the device]

 By the way, in such a resin sheet, the sheet body and the sheet legs are connected and fixed before being attached to the floor surface, and the assembled resin sheet is carried to a predetermined position by a worker's hand. However, since the seat leg is located below the seat body, the seat body, especially the cushion portion, obstructs the seat body, making it difficult for the operator to see. Further, in the posture with the resin sheet, the feet, that is, the mounting position of the resin sheet, is likely to be a blind spot for the operator.

Therefore, the resin sheet cannot be easily positioned with respect to the floor surface, and the workability is unavoidably deteriorated. Usually, in such a case, the resin sheet is attached to the floor so that the operator can easily see the resin sheet even when the operator holds the resin sheet. However, in such a configuration, it takes a lot of time for scribing and the work accuracy is poor, so that workability also decreases in this respect.

[0006] The operator raises and lowers the resin sheet and positions it until the resin sheet is accurately positioned, which imposes a heavy weight burden on the seated person, and also from this point, the workability is deteriorated. Is inevitable.

In addition, at a position adjacent to a wall or another obstacle, the work space required for the bolt tightening work may not be sufficiently secured on the side of the resin sheet. However, the resin sheet cannot be easily used in a wide range.

An object of the present invention is to provide a resin sheet structure that facilitates positioning and bolt tightening work to improve workability.

[0009]

[Means for Solving the Problems]

 In order to achieve this object, according to the present invention, the portion where the cushion body is embedded is formed in the seat body as a through hole having a corresponding shape. After the resin sheet is fixed to the floor surface by bolting the seat leg, the through hole can be closed by fitting and fixing the cushion body in the through hole of the seat body.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIGS. 1 and 2, in a resin sheet structure 10 according to the present invention, a resin leg 16 having a predetermined shape is assembled by fixing a seat leg 14 to a sheet body 12.

The seat body 12 is formed by blow molding of synthetic resin or the like into an integral shape of the cushion portion 12a and the back portion 12b, and a cushion body 21 described later is embedded in the cushion portion. The seat body and the seat leg 14 are connected by inserting the mounting piece 20 into the recess 18 and tightening the seat body 12 and the mounting piece 20 together with the bolt 22 and the nut 24.

It should be noted that such a configuration is publicly known, and the configuration itself is not the purpose of the present invention, and therefore will not be described in detail here.

By the way, such a resin sheet 16 is fixed to a predetermined position on the floor surface 26 by, for example, bolting after the seat legs 14 are attached to the seat body 12. However, it is difficult for an operator who holds the resin sheet 16 to see the attachment positions of the seat leg 14 and the floor surface 26, so that it is difficult to arrange the resin sheet on the floor surface.

Therefore, as can be seen from FIG. 1, in the present invention, a through hole 28 having a corresponding shape is provided at a predetermined position of the seat body 12 in which the cushion body 21 is embedded, and through the through hole, The seat leg 14 and the mounting position of the floor surface are made easy for the operator to see. Then, as shown in FIGS. 1 and 2, after the resin sheet 16 is attached to the floor surface 26, the cushion body 21 is fitted and fixed in the through hole 28 of the seat body so that the through hole can be closed. There is.

The cushion body 21 is formed of an elastic body such as urethane into a substantially square shape so as to elastically support the seated portion of the seated person, and the through hole 28 corresponds to the cushion body 21. It is formed in a similar rectangular shape.

Here, as shown in FIGS. 1 and 2, a step portion 28a is formed on the peripheral edge of the through hole 28, and a protrusion 21a engageable with the step portion of the through hole is formed in the cushion body 21. It is projected like a flange on the circumference of the. The stepped portion 28a of the through hole and the protruding portion 21a of the cushion body are both formed over the entire circumference, for example.

The cushion body 21 is, for example, inserted into the through hole 28 of the seat body together with the support panel 30 having the inner flange-shaped receiving surface 30a on the two opposite lower surfaces. The support panel 30 is molded with a flange 30b at the upper end that can be engaged with the step portion 28a at the peripheral edge of the through hole, and the flange is sandwiched between the protruding portion 21a of the cushion body and the step portion 28a of the through hole. Thus, the receiving surface 30a at the lower end is arranged to receive the lower surface of the cushion body. The support panel 30 is irremovably fixed to the through hole 28 of the seat body, for example.

As shown in FIG. 2, the cushion body 21 and the support panel 30 are detachably connected by, for example, a connection member 32 interposed between the lower surface of the cushion body and the receiving surface 30a of the support panel. ing.

As the connecting member 32, for example, a pair of belt-shaped Velcro tapes (registered trademark) of male and female can be used. One of the male and the female is the receiving surface 30a of the support panel and the other is the cushion body 21. They are fixed to the corresponding locations on the lower surface.

Then, by inserting the cushion body 21 into the through hole 28 through the support panel 30 and connecting the connecting member (Velcro tape) 32, the through hole 28 of the seat body is closed by the cushion body. .

In such a configuration, since the through hole 28 is formed in the cushion portion 12a of the seat body, the operator lifts the resin sheet 16 and inserts the sheet body 12 through the through hole. It is possible to easily confirm the mounting position of the seat leg 14, the floor surface 26, etc. Therefore, the work of disposing the resin sheet 16 can be easily performed, and the workability at the time of attaching the resin sheet is sufficiently improved.

Further, since the positional relationship between the seat leg 14 and the mounting position of the floor surface 26 and the like can be easily confirmed, it is not necessary to provide positioning on the floor surface or the like. Therefore, it is possible to sufficiently prevent complication of work at the time of mounting, and workability is improved also from this point.

Further, after the resin sheet 16 is attached to the floor surface 26, it is sufficient to fit and fix the cushion body 21 in the through hole 28, and also in this respect, the complication of workability can be sufficiently prevented. .

Further, since the through-hole 28 of the seat body is located above the seat leg 14, the bolt tightening work can be performed using the through-hole when fixing the seat leg to the floor surface 26. . Therefore, it is not necessary to secure a working space on the side of the resin sheet 16 or the like, and it is possible to sufficiently attach the resin sheet to a position or the like where a space cannot be secured on the side or the like. Therefore, the usage range of the resin sheet 16 is sufficiently expanded, and the resin sheet can be sufficiently used even in a narrow vehicle interior or on a wall.

Here, in the embodiment, the cushion body 21 is detachably connected to the support panel 30. That is, the cushion body 21 can be easily removed even after being attached to the seat body 12. However, the present invention is not limited to this, and the cushion body 21 may be irremovably fixed to the seat body 12 after the resin sheet is attached to the floor surface 26.

However, if the cushion body 21 can be detached from the seat body 12 as in the embodiment, after the resin sheet 16 is attached to the floor surface 26, cleaning under the seat body and the seat body are prevented. Maintenance of the heater unit located below can be easily performed.

Further, in the embodiment, a pair of male and female Velcro tapes are exemplified as the connecting member 32, but it is sufficient if the cushion body 21 is detachably connected to the support panel 30, The configuration is not limited to this, and the cushion body and the support panel may be connected to each other by, for example, a combination of a magnet and a metal plate.

However, when the Velcro tape is used as the connecting member 32, a reliable connected state can be easily obtained, and the cushion body 21 is pulled by pushing the cushion body 21 from the lower surface or the like. Since it can be easily removed from the machine, the structure is simplified and workability can be reliably prevented from becoming complicated.

Further, the connecting member 32 is disposed between the receiving surface 30a of the support panel and the lower surface of the cushion body 21, but the connecting member 32 is not limited to this, as long as it can be overlapped between the both. For example, a connecting member may be interposed between the lower surface of the protruding portion 21a of the cushion body and the upper surface of the stepped portion 28a of the through hole.

Further, the protruding portion 21a of the cushion body and the stepped portion 28a of the through hole are formed in a continuous shape over the entire circumference, but it is sufficient to prevent the cushion body from falling off, so this is not a limitation. Instead, for example, an intermittent protrusion or step may be provided on each.

If the protrusion 21a of the cushion body and the stepped portion 28a of the through hole have rigidity that does not easily change the shape, the protrusion and the stepped portion are provided only on two opposing surfaces, respectively. May be

Although a resin sheet attached to a vehicle or the like is illustrated here, the present invention is not limited to this, and the present invention may be applied to a resin sheet such as a train platform or a waiting room of various facilities.

The above-mentioned embodiments are for explaining the present invention, and do not limit the present invention in any way, and all the modifications and alterations made within the technical scope of the present invention are also applicable. It goes without saying that it is included in the invention.

[Effect of device]

 As described above, according to the resin sheet structure of the present invention, the operator can easily visually recognize the positional relationship such as the seat leg and the mounting position of the floor surface through the through holes, and therefore the positioning and the like can be performed. The disposition work of the resin sheet can be easily performed without providing. Therefore, workability at the time of attaching the resin sheet to the floor surface is sufficiently improved.

Since the through hole of the seat body is located above the seat leg, the bolt tightening operation can be performed using the through hole when fixing the seat leg to the floor. Therefore, it is not necessary to secure a working space on the side of the resin sheet or the like, and the range of use of the resin sheet is sufficiently expanded.

Further, if the stepped portion is provided on the peripheral edge of the through hole and the flange-shaped projecting portion is provided on the peripheral surface of the cushion body, the rigidity for receiving the load of the seated person can be easily ensured, and thus the structure , It is possible to prevent the cushion body from coming off the seat body without complicating the shape.

If the cushion body can be detached from the seat body via the connecting member, the cushion body can be cleaned below the seat body or placed below the seat body after the resin sheet is attached to the floor surface. Easy maintenance of the heater unit.
