JP 2005-270498 A Japanese Patent No. 4114830

The article support member described in Patent Document 1 has a circular base portion that supports the lower surface of the beverage container and a cylindrical portion that rises upward from the periphery of the base portion. can be held stably. However, in the case of this article support member, even when the beverage container is not placed on the base portion, the base portion and the cylindrical portion protrude in the width direction of the armrest. Therefore, the lower leg of the user sitting on the chair hits the article support member, and the space below the armrest cannot be widely used.

On the other hand, the article support member described in Patent Document 2 has a structure in which the cup holding portion can be stored in the armrest when the beverage container, which is the article to be placed, is not placed. The space on the lower side of the armrest can be widely used when the armrest is not placed on the armrest. However, in the case of this article support member, it is difficult to stably support the beverage container because it is structured to support only the upper peripheral area of the beverage container by the annular cup holding portion having a narrow vertical width.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a chair equipped with an article support member that can stably support an article and that allows the lower space to be widely used when no article is placed on the chair. be.

In order to solve the above problems, the chair of the present invention employs the following configuration.
That is, the chair of the present invention includes a plurality of pedestals installed on the floor, a seat constructed over the adjacent pedestals, armrests provided on the top of the pedestals, and the armrests arranged on the pedestals. an article support member, the article support member comprising an upper support body having a support hole capable of supporting an upper peripheral area of the article; and a lower part disposed below the support hole and capable of supporting the lower surface of the article. a support, wherein the width of the lower support in a first direction substantially perpendicular to the vertical direction is narrower than the width of the support hole , and the rear end of the lower support is coupled to the pedestal. It is characterized by

With the above configuration, when an article is inserted into the support hole of the upper support, the article is supported on its lower surface by the lower support and supported by the support hole of the upper support on its upper peripheral area. Since the width of the lower support in the first direction substantially orthogonal to the vertical direction is narrower than the support hole, when no article is placed on the lower support, below the upper support, Doesn't occupy much space in the first direction. Therefore, when no article is placed, the space on the lower side of the upper support can be widely used, and the user's body is less likely to come into contact with the lower support.

The lower support includes a lower surface support portion that is arranged below the support hole and supports the lower surface of the article. The length may be longer than the width of the support hole.
In this case, the lower surface supporting portion arranged below the supporting hole has a length in the second direction longer than the width of the supporting hole, so that the lower surface of the article can be stably supported below the supporting hole. can do.

The lower support may be arranged such that the article support surface of the lower support is spaced downward from the support hole of the upper support.
In this case, since the lower support is arranged below the upper support while securing an article placement space below the support hole, the article storage section is sufficiently deep below the support hole of the upper support. can be formed.

At least part of the lower support may be supported by the upper support.
In this case, the lower support supporting the lower surface of the article is stably supported by the upper support. Further, for example, even if the user's body touches the lower support when no article is placed on the article support member, the lower support can be prevented from rattling or coming off.

The lower support may further include an upwardly extending portion extending upward from the end of the lower surface support in the second direction and coupled to the upper support.
In this case, by simply connecting the upwardly extending portion extending upward from the end portion of the lower surface support portion to the upper support portion, the article storage portion having a sufficient depth can be formed below the support hole of the upper support portion. can be done. Therefore, when this configuration is adopted, the article can be stably supported by a simple configuration with a small number of parts.

The upward extending portion may be provided at one end portion and the other end portion of the lower surface support portion in the second direction.
In this case, both longitudinal ends of the lower support portion of the lower support are coupled to the upper support via the upwardly extending portions, so that the article placed on the lower support is stabilized by the double support structure. can be supported on the upper support.

The lower support is made of a plate material, and is arranged below the support hole such that the thickness direction of the lower support coincides with the first direction, and the width in the first direction is equal to the thickness of the lower support. may be the width of
In this case, the rigidity in the vertical direction of the lower support can be ensured by the sufficient width of the lower support in the vertical direction. Therefore, it is possible to stably support the lower surface of the article placed on the lower support.

The lower support may be arranged below the armrest such that the width in the first direction is aligned with the width direction of the seat.
In this case, when the user sits on the seat, the lower legs of the seated user are positioned inside and below the side portions of the armrests. At this time, since the width of the lower support, which is narrower than the support hole, is aligned with the width direction of the seat, the legs of the seated user interfere with the lower support when no article is placed on the article support member. difficult to do.

According to the present invention, the width of the lower support in the first direction, which is substantially perpendicular to the vertical direction, is narrower than the support hole of the upper support. Therefore, the peripheral area and the lower surface of the article can be stably supported by the upper support and the lower support. Can be used widely.

The chair of this embodiment is configured as a connected chair 1 in which two chairs 10 are integrally connected side by side. A predetermined number of connecting chairs 1 are arranged in a horizontal row on the floor surface of the facility. Here, a connected chair 1 in which two chairs 10 are connected is illustrated, but the number of chairs 10 to be connected is not limited to two and is arbitrary. A plurality of horizontal rows of the connecting chairs 1 are installed on the floor spaced apart from each other by a predetermined distance in the front-rear direction. Also, the chair 10 may be a single chair instead of the connecting chair 1 . In this embodiment, the chair 10 constitutes furniture.

The connecting chair 1 has a plurality of (three) pedestals 11 fixedly installed on the floor at predetermined intervals in the left-right direction, and the adjacent pedestals 11 are bridged to support the buttocks of the seated user. and a plurality of (two) backrests 13 that support the back of the seated user supported by the adjacent pedestals 11 . In the connecting chair 1, a seat 12 and a backrest 13 of each chair 10 are arranged between adjacent pedestals 11. - 特許庁In this embodiment, the pedestal 11 constitutes a support structure for the chair 10, which is furniture.

The pedestals 11 arranged on both the left and right sides of each chair 10 are provided with a main support 11a whose lower end is fixed to the floor surface by an anchor bolt or the like, and a support plate 11b coupled and fixed to the upper side surface of the main support 11a. ing. The main support column 11a stands vertically upward from the floor surface side. The support plate 11b is formed in a substantially rectangular shape when viewed from the side, and a flange portion (not shown) for fixing the backrest 13 is provided at the rear end portion thereof. The backrest 13 is supported by the supporting plates 11b of the adjacent left and right pedestals 11. As shown in FIG. A decorative plate 31 is attached to the pedestal 11 positioned at the outer side edge of the connecting chair 1 . The decorative plate 31 covers the upper region of the main support 11a of the pedestal 11 and the outer side surfaces and the front surface of the support plate 11b.

An armrest 16 is attached to the top of each pedestal 11 . The armrest 16 includes an armrest substrate 16A integrally attached to the upper end of the pedestal 11 and an outer layer member 16B attached to the armrest substrate 16A to cover the upper surface and peripheral area of the armrest substrate 16A.

The armrest base plate 16A is made of a rectangular plate material that is larger than the upper end surface of the pedestal 11 in plan view. The front end of the armrest base plate 16A is positioned substantially aligned with the front end of the pedestal 11, and the rear end of the armrest base plate 16A extends to the vicinity of the backrest 13. As shown in FIG. Further, the left and right side edges of the armrest base plate 16A protrude outward in the width direction from the left and right side surfaces of the pedestal 11 .

The outer layer member 16B is formed to be one size larger than the armrest substrate 16A in a plan view, and has a rectangular concave portion in which the armrest substrate 16A is fitted. The outer layer member 16B attached to the armrest substrate 16A has a substantially uniform thickness in the vertical direction and a substantially flat upper surface. The outer layer member 16B extends forward from the vicinity of the backrest 13 of the chair 10 . The width of the outer layer member 16B in the left-right direction is not constant, but gradually increases from the rear side toward the front. In this embodiment, the armrest 16 constitutes a functional surface structure. A flat upper surface 16b of the armrest 16 (outer layer member 16B) constitutes the functional surface of the functional surface structure.

A front edge portion of the armrest 16 configured by the outer layer member 16B protrudes forward from the front end portion of each pedestal 11 . Hereinafter, the portion of the armrest 16 that protrudes forward from the front end portion of each pedestal 11 will be referred to as a forward extending portion 16a. In this embodiment, the forward extension 16a of the armrest 16 constitutes the upper support for the article support member 30. As shown in FIG. A circular support hole 20 penetrating vertically is formed in the front extending portion 16a. An article such as a beverage container is inserted into the support hole 20 . The inner peripheral wall surface of the support hole 20 can support the upper peripheral area of the inserted article. A receiving plate 21 that constitutes a lower support of the article support member 30 is attached to the lower surface of the forward extending portion 16a.

The receiving plate 21 is attached to the lower surface of the forward extending portion 16 a so that the thickness direction of the plate faces the width direction of the chair 10 . The receiving plate 21 is arranged below the forward extending portion 16a so as to cross substantially the central portion of the support hole 20 in the front-rear direction. The thickness of the receiving plate 21 is set to be at least one-third or less of the diameter D of the support hole 20 (the width of the article storage portion). The receiving plate 21, which is a lower support, has a plate width (width in the first direction) substantially perpendicular to the vertical direction that is narrower than the diameter D of the support hole 20 (width of the article storage portion). The length of the support portion 21a in the front-rear direction (the length in the second direction) is longer than the diameter D of the support hole 20 (the width of the article storage portion). The length of the entire receiving plate 21 in the front-rear direction (the length in the second direction) is naturally longer than the diameter D of the support hole 20 (the width of the article storage portion).

As shown in FIG. 4, the receiving plate 21 includes a lower surface support portion 21a arranged below the support hole 20 of the armrest 16 to support the lower surface of the article, and front and rear ends (longitudinal direction) of the lower surface support portion 21a. and a pair of upwardly extending portions 21b extending upwardly from one end and the other end of the armrest 16 and having an upper end coupled to the lower surface of the forwardly extending portion 16a of the armrest 16 . The front and rear upwardly extending portions 21b are arranged at positions separated from the lower portion of the support hole 20 in the front and rear direction. Therefore, when the receiving plate 21 is attached to the lower surface of the armrest 16, the upper surface (article supporting surface) of the lower surface support portion 21a is positioned downward from the lower surface of the armrest 16 (forward extending portion 16a) below the support hole 20 by a predetermined amount. Keep distance. Thereby, an article arrangement space is secured below the support hole 20 . Also, the rear end of the receiving plate 21 is connected to the pedestal 11 that supports the armrest 16 .

Further, the seat 12 is supported by the left and right adjacent pedestals 11 so as to be able to flip up and rotate. Specifically, support shafts 22 extending in the width direction of the chair are provided between the left and right adjacent pedestals 11, and the seat 12 is rotatably supported on the support shafts 22. As shown in FIG. The seat 12 is tilted substantially horizontally forward when in use, and flipped up rearward by the force of a return spring (not shown) when not in use.

The forward extending portions 16a of the armrests 16 are arranged on the left and right sides of the seat 12 that is reclined forward. The plate width of the receiving plate 21 (lower support) arranged below the forward extending portion 16 a matches the width direction of the seat 12 .

In this embodiment, when an article such as a beverage container is inserted into the support hole 20 in the front portion of the armrest 16, the bottom of the article is supported by the upper surface of the lower surface support portion 21a of the receiving plate 21, and the article is held. The upper peripheral area is surrounded by the support hole 20 (it is made possible to be supported by the inner peripheral wall surface of the support hole 20). In this state, the article is stably placed on the front portion of the armrest 16 because the article support member 30 supports the article at its bottom and upper periphery. In particular, the receiving plate 21 has a width of 1/3 or less of the diameter D of the support hole 20. The lower surface of the article can be supported with good balance. In addition, the receiving plate 21 is set so that its vertical width (height) is sufficiently large relative to its plate thickness (horizontal width). Therefore, the receiving plate 21 can support the bottom surface of the article with high rigidity.

As described above, in the article support member 30 of the present embodiment, the lateral width of the receiving plate 21 is formed narrower than the diameter D of the support hole 20 (the width of the article accommodating portion). Therefore, in the article support member 30 of the present embodiment, the upper peripheral area and the lower surface of the article can be stably supported by the support hole 20 and the support plate 21 of the forward extending portion 16a. Since the receiving plate 21 does not protrude greatly toward the seat 12 when no article is placed thereon, the space on the lower side of the forward extending portion 16a of the armrest 16 can be used widely. For example, even when the user sitting on the seat 12 moves the leg in the left-right direction, the user's leg is less likely to interfere with the receiving plate 21 below the armrest 16 .

In the article support member 30 of the present embodiment, the length of the lower surface support portion 21a of the receiving plate 21 in the front-rear direction is longer than the diameter of the support hole 20 (the width of the article storage portion). can stably support the lower surface of the article.

In addition, in the article support member 30 of the present embodiment, the article support surface of the receiving plate 21 that is the lower support is arranged so as to be spaced downward from the support hole 20 of the armrest 16 . That is, the receiving plate 21 is supported by the forward extending portion 16a of the armrest 16 in a state in which a space for placing articles is secured below the support hole 20. As shown in FIG. Therefore, it is possible to form an article storage section with a sufficient depth below the support hole 20 in the front portion of the armrest 16 .

In particular, in the article support member 30 of the present embodiment, the support plate 21, which is the lower support body, is coupled to the forward extending portion 16a of the armrest 16, so that the support of the support plate 21 can be stabilized. Therefore, when the article support member 30 of the present embodiment is employed, it is possible to stabilize the support of the placed article and prevent the leg of the seated person from touching the receiving plate 21 when no article is placed. Even if there is, the receiving plate 21 can be prevented from rattling or coming off.

In the case of the article support member 30 of this embodiment, the receiving plate 21 includes a lower surface support portion 21a arranged below the support hole 20 to support the lower surface of the article, and a longitudinal direction (second direction) of the lower surface support portion 21a. and an upwardly extending portion 21b extending upwardly from the end portion and coupled to the forwardly extending portion 16a of the armrest 16 . For this reason, by simply connecting the upwardly extending portion 21b extending upwardly from the end portion of the receiving plate 21 to the forwardly extending portion 16a of the armrest 16, an article storage portion having a sufficient depth below the support hole 20 can be formed. can be formed. Therefore, when the structure of the present embodiment is adopted, it is possible to stably support the placed article while the number of parts is small and the structure is simple enough to reduce the manufacturing cost.

In particular, in the case of the article support member 30 of the present embodiment, the upper extending portions 21b are provided on the front end side and the rear end side of the lower surface supporting portion 21a of the receiving plate 21, and the front and rear upward extending portions 21b are located in front of the armrest 16. It is connected to the extension 16a. Therefore, when the article support member 30 of the present embodiment is adopted, the article placed on the receiving plate 21 can be stably supported by the armrest 16 by the double support structure.

Further, the chair 10 of the present embodiment includes an article support member 30 and an armrest 16 (functional surface structure) having a functional surface (upper surface 16b) facing upward. A part (forward extending portion 16 a ) is formed integrally with the armrest 16 . Therefore, a user seated on the seat can easily grasp an article placed on the article support member 30 while resting his arm on the upper surface 16 b of the armrest 16 . Therefore, when the chair 10 of this embodiment is employed, a seated user can stably handle the article on the article support member 30 .

Furthermore, in the chair 10 of this embodiment, the support plate 21 of the article support member 30 is connected not only to the armrest 16 but also to the pedestal 11 which is the support structure of the chair 10 . Therefore, the load of the article placed on the receiving plate 21 can be stably supported by the armrest 16 and the pedestal 11 . Further, in the chair 10 of the present embodiment, since the receiving plate 21 is supported by the armrest 16 and the pedestal 11 with high rigidity, the chair 10 can be seated on the seat 12 without an article placed on the article support member 30. Even if the lower leg of the user comes into contact with the receiving plate 21, the receiving plate 21 can be prevented from rattling or coming off.

In the above-described embodiment, the receiving plate 21 that constitutes the lower support of the article support member 30 is composed of a single plate. , may be configured by a plurality of receiving plates 21A and 21B arranged substantially in parallel. Also in this case, the total width of the plurality of receiving plates 21A and 21B in the arranged state should be set to at least one-third or less of the diameter D of the support hole 20 (article accommodation width).

In the above-described embodiment, the receiving plate 21, which is the lower support body of the article support member 30, is connected to the forward extending portion 16a of the armrest 16 at the front and rear upward extending portions 21b.
