Description

  The present invention relates to a chair installed in an open space of a public facility such as a hospital waiting room, a hotel lobby, or an airport, for example, in which a plurality of seats composed of a seat and a backrest are supported by a common leg.

  As described above, as a chair in which a plurality of seats are supported by a common leg, for example, as described in Patent Documents 1 and 2, a chair in which a plurality of seats are continuously arranged integrally, or a patent As described in Documents 3 and 4, there are some in which a plurality of adjacent seats are separated from each other.

Registered Utility Model No. 3037917 (page 9, FIG. 1) JP2011-83526A (4th page, FIG. 1) JP 2001-161696 A (page 3, FIG. 1) JP 2009-77764 A (page 3, FIG. 1, FIG. 2)

  However, as in the chairs described in Patent Documents 1 and 2, if a plurality of seats are continuously arranged integrally, it becomes difficult to understand the boundaries of the seats used by each person. May not be possible.

  On the other hand, in the chairs described in Patent Documents 3 and 4, the adjacent seats are separated from each other, and thus the above problem does not occur. However, since the chair described in Patent Document 3 has a gap between adjacent seats, there is a risk of dropping an object from the gap or causing a child's hand or foot to enter the gap and cause an unexpected injury. There is. In order to prevent such a problem from occurring, in the chair described in Patent Document 4, a gap between adjacent seats is closed by a spacer. However, this spacer is separate from the chair, and since the spacer is fixed to the bracket that supports the opposing portions of the seats adjacent to each other with screws, it takes time and effort to install the spacer. The number of points increases and the cost becomes high. Moreover, there is a possibility that vibration at the time of sitting is transmitted to an adjacent seat through the spacer.

  The present invention has been made paying attention to such a problem, so that vibrations can be prevented from being transmitted to adjacent seats, and a gap between adjacent seats can be easily closed. The purpose is to provide a chair.

In order to solve the above problems, the chair of the present invention is
In a chair in which a plurality of seats composed of a seat and a backrest are supported on a common leg while being separated in the left-right direction,
One side end surface of the seat plate constituting one of the seats adjacent to each other is adjacent to or abuts on the other side end surface of the seat plate constituting the seat of the other seat on the side of the seat of the other seat. Thus, it is characterized in that it extends sideways toward the other seat side, and this extended portion is a cover portion in the front-rear direction that closes a gap formed between adjacent seats.
According to this feature, the seat plate constituting the one of the seat in a seat adjacent to each other, simply by extending the seat plate side which constitutes the seat of the other seating, easily gap Zama adjacent to each other Can be occluded. Therefore, it is not necessary to manufacture a separate cover and attach it to the leg or the seat, and the cost can be reduced by reducing the number of parts and the number of mounting steps. Moreover, since the cover part is not connected to the other seats adjacent to each other, it is possible to prevent the vibration at the time of sitting from being transmitted to the other seat through the cover part.

The chair of the present invention
One side end surface of the back plate constituting one of the backrests of the seats adjacent to each other is close to or close to the other side end surface of the back plate constituting the backrest of the other seat and the other backrest side.

  Embodiments of the present invention will be described based on the following examples.

  The chair according to the first embodiment will be described with reference to FIGS. The chair according to the first embodiment of the present invention supports a plurality of left and right (two in the embodiment) seats 2 and 2 ′ spaced apart in the left-right direction on a common leg 1 facing in the left-right direction when viewed from the front. It's more of a thing.

  The leg body 1 includes a pair of left and right support legs 3 and 3 each having a pair of front and rear leg rods 3a and 3a that expand in a front-and-rear direction in a side-view mountain shape, and a recess at the upper end of both left and right support legs 3 Both left and right ends of the groove 4 are fitted from above, and a rectangular tubular beam 5 fixed by screws (not shown) is provided. At the upper ends of the left and right support legs 3, 3, the central part of the support brackets 6, 6 that are L-shaped in a front view is fixed with screws (not shown) so as to straddle the upper half of the beam 5. In addition, two left and right support brackets 6 and 6 having the same shape as the above are sandwiched between the lower fixing members 7 and 7 at the center of the beam 5 in the left and right direction so It is fixed.

  The left and right seats 2, 2 'are each composed of a seat 8 and a backrest 9, and the seat 8 and the backrest 9 are integrally formed with a seat plate 10, 10' and a back plate 11, 11 '. And cushioning materials 12 and 12 attached to the upper surface and the front surface thereof. One of the seats 2 and 2 'adjacent to each other, that is, the seat plate 10 and the back plate 11 in the left seat 2 in the front view in this embodiment, leave the cushion material 12 and the seat plate in the right seat 2'. 10 'and the back plate 11' are extended outward in a direction opposite to the left end (see FIG. 4). As a result, the left and right seats 2 and 2 ′ are left-right asymmetric. This extension part closes the gap formed between the adjacent seats 2, 2 ′ when both seats 2, 2 ′ are attached to the leg 1 so as to be separated from each other in the left-right direction, as will be described later. The cover portion 13 in the direction and the cover portion 14 in the up and down direction continuous to the rear end thereof (see FIG. 5).

  The lower surface of the both side end portions of the seat plate 10, 10 'and the lower rear surface lower portion of the back plate 11, 11' are supported by the support bracket 6 at the side end portion and the support bracket 6 at the center portion, The left and right seats 2, 2 ′ are supported by the legs 1 so as to be separated from each other in the left-right direction via the left and right support brackets 6 by being fixed with screws that are not used. At this time, the side end surfaces of the front and rear cover portions 13 and the vertical cover portion 14 extending from the seat plate 10 and the back plate 11 in the left seat 2 are the seat plates 10 ′ in the right seat 2 ′. By attaching the left and right seats 2, 2 'to the leg 1 so as to be close to or in contact with the side end surface of the back plate 11', the gap formed between the adjacent seats 2, 2 'is closed. . Accordingly, it is possible to prevent an object from falling through the gap and a child's hand or foot from entering the gap.

  As described above, in the chair according to the first embodiment, the seat plate 10 and the back plate 11 in the left seat 2 are arranged close to the left end of the seat plate 10 ′ and the back plate 11 ′ in the right seat 2 ′. Since it extends outward so as to abut, and this extended part is a cover part 13 in the front-rear direction and a cover part 14 in the vertical direction that closes the gap formed between the seats 2 adjacent to each other. It is not necessary to manufacture the cover and attach it to the leg body 1 or the seat 2, and the cost can be reduced by reducing the number of parts and the number of mounting steps. Moreover, since the cover parts 13 and 14 are not connected with the right seat 2, it can suppress that the vibration at the time of seating is transmitted to the mutually adjacent seats 2 via the cover parts 13 and 14.

  Further, the gap between the backrests 9 and 9 of the seats 2 and 2 ′ adjacent to each other can be easily closed by the vertical cover portion 14 extending from the back plate 11 of the backrest 9. Further, if the gap between the backrests 9 and 9 is also closed, the seated person in the front chair cannot be seen from the rear of the chairs arranged side by side in the front-rear direction.

  Furthermore, since only the seat plate 10 and the back plate 11 are extended while leaving the cushion material 12, the boundary of the seat 2 used by each person can be easily identified using the cushion material 12 as a guide.

  The integrally formed seat plate 10 and back plate 11 are extended laterally, and the front-rear direction cover portion 13 and the up-down direction cover portion 14 are continuous. The two covers for 9 are not necessary, and can be continuously and firmly sealed from the gap between the seats 8 to the gap between the backrests 9.

  Further, when the front-rear cover portion 13 and the vertical cover portion 14 are made continuous, their bending rigidity increases. For example, as shown in FIG. 6A as a first modification of the present invention. An optional member such as an armrest 15 or a holder 16 for a cup or a stick can be stably attached to the cover portion 13 in the front-rear direction and the cover portion 14 in the up-down direction. Furthermore, since the area in the width direction of these cover portions 13 and 14 can be expanded, the contact area of an optional member such as an armrest 15 or a cup or a stick holder 16 attached to these cover portions 13 and 14 can be increased. The option member can be securely fixed to the cover portions 13 and 14. In FIG. 6A, each end portion of the substantially L-shaped armrest 15 as an optional member is joined to a front-rear direction cover portion 13 and a vertical direction cover portion 14 such as a bolt (not shown). Since the armrests 15 are joined at a plurality of positions, for example, compared to a conventional option member that is joined at only one position with respect to a beam appearing between adjacent seats. Stability is remarkably high.

  Further, for example, as shown in FIG. 6 (b) as a second modification of the present invention, an armrest 15 'as an optional member is integrally formed or fixed in advance on the right seat 2' and front and rear of the left seat 2 The substantially U-shaped cutout portions 17 and 18 are formed at appropriate positions on the cover portion 13 ′ in the direction and the cover portion 14 ′ in the vertical direction so that the cutout portions 17 and 18 are fitted to the armrests 15 ′. Both seats 2 and 2 'may be assembled. By doing so, the armrest 15', which is an optional member, can be more stably provided on the seat 2 '.

  FIG. 7 shows a perspective view of a chair according to Embodiment 2 of the present invention. In this embodiment, only the seat plate 10 in the seat 8 of the left seat 2 ″ is replaced with the seat 8 of the right seat 2 ′. Is extended outward so as to be close to or in contact with the left end of the seat plate 10 ′, and this extended portion serves as a cover portion 13 in the front-rear direction. In the second embodiment, the back plate 11 ′ in the backrest 9 of the left seat 2 ″ is formed to have substantially the same width as the backplate 11 ′ in the backrest 9 of the right seat 2 ′. A gap having a predetermined width is formed between the back plates 11 ′ and 11 ′.

  Like the chair of the second embodiment, only the seat plate 10 in the seat 8 of the left seat 2 ″ is extended outward, and the extension portion is used as a cover portion 13 in the front-rear direction. Since the gap formed between the sitting seats 8 is closed by the cover portion 13, it is possible to prevent an object from falling through the gap and a child's hand or foot from entering the gap. In addition, the same effects as those of the first embodiment can be obtained.

  The present invention is not limited to the above embodiments. In the above embodiment, the seat 8 and the backrest 9 in the seat 2 are provided with the cushioning material 12 on the surface of the seat plate 10 and the back plate 11. However, the seat 8 and the backrest 9 are respectively provided on the seat plate 10. Further, only the back plate 11 may be formed integrally with them. In this case, as in the above embodiment, both the seat plate 10 and the back plate 11 of the left seat 2 or only the seat plate 10 may be extended to the right seat 2 side. In this case, it is considered that the boundary of the seat 2 used by each person becomes difficult to understand, but if a recess or the like into which the seated part of the occupant slightly enters is formed on the upper surface of the seat plate 10 of the seat 2 adjacent to each other. There is no risk of such problems occurring.

  In the seat 2 of the above embodiment, the seat 8 and the backrest 9 are integrally formed, but the present invention can also be applied to a chair attached to the leg 1 as a separate body. In this case, the seat plate 10 and the back plate 11 are extended separately. However, if the rear end and the lower end of the extension portions are brought into contact with each other, the appearance appearance is impaired. There is no.

  The chair of the above embodiment has two left and right seats 2, but it can be applied to a chair having three or more seats 2, for example. In this case, a seat applied to a chair having three or more seats has a plurality of seats 2, 2,... With side end surfaces extending laterally toward the other seat side, and such extension portions. The first seat 2 'is arranged at the end.
