Description

The present invention relates to chairs.

2. Description of the Related Art As a sofa-type chair used in facilities such as hospitals, there is a chair in which grounding members such as low-height grounding legs and casters are attached to the lower surface of a support structure that supports a seating portion. In this type of chair, since a space is formed between the floor surface and the support structure, it is possible to improve the comfort of the sitting part and the ventilation under the support structure.

However, in this type of chair, a space with a narrow vertical width is formed under the support structure, so that when a small article gets caught under the support structure, it becomes difficult to take out the small article.

As a countermeasure, a plate-like shielding wall is provided around the lower side of the support structure (see, for example, Patent Document 1).
In the chair (wagon-type tool) described in Patent Document 1, a plate-shaped shielding wall extending downward toward the floor surface is arranged around the lower surface of the support structure. The shield wall extends linearly from the lower surface of the support structure to a position close to the floor surface, and the gap between the extended end and the floor surface is narrowed as much as possible.

JP 2008-79677 A

However, in the above-described conventional chair, the base portion of the shielding wall extending toward the floor is made of a hard member such as wood or resin. When the chair is moved, the lower end of the shielding wall may come into contact with the projection on the floor surface, causing damage to the shielding wall.

In addition, in the above-mentioned conventional chair, it is difficult to bring the extending end of the shielding wall sufficiently close to the floor as described above. can penetrate under the support structure through In addition, even if the extended end of the shielding wall can be sufficiently brought close to the floor, if there is a slight dent in the floor, a small thin object will be caught in the gap between the floor and the shielding wall created by the dent. may enter.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a chair that can more reliably prevent articles from entering the lower part of a support structure.

A chair according to the present invention employs the following configuration in order to solve the above problems.
That is, the chair according to the present invention includes a support structure that supports a seating portion and is in contact with the floor surface, and a support structure that is disposed on the front side of the seating direction of the support structure, and whose lower end contacts the floor surface so as to be able to follow and deform. and a shielding member.

With the above configuration, the shielding member arranged on the front side of the support structure deforms (according to the distance between the support structure and the floor surface) following the shape of the floor surface and comes into contact with the floor surface. Therefore, even if the floor surface has some unevenness, the shielding member is in contact with the floor surface, and a gap is less likely to be formed between the floor surface and the shielding member. As a result, even a thin article such as a card is prevented from entering below the support structure by the shielding member.

The support structure includes a structure main body portion that supports the seating portion, and a structure main body portion that is disposed under the structure main body portion. and a grounding member to be provided.

In this case, since a separate grounding member is attached to the structure main body, the stability of the support structure on the floor surface can be easily enhanced by adjusting the height and grounding surface of the grounding member.

It is desirable that the shielding member is made of an elastic member.

In this case, since the lower end of the shielding member is pressed against the floor surface by the elasticity of the member, even if the floor surface is slightly uneven, a gap is less likely to occur between the floor surface and the shielding member.

The shielding member may extend continuously in the width direction of the chair.

In this case, since the lower end of the shielding member comes into contact with the floor without interruption in the width direction of the chair, it is possible to further prevent articles from entering the lower part of the support structure.

The shielding member may have an elastically deformable hollow cross-sectional portion continuously extending in the width direction of the chair.

In this case, since the lower end of the hollow section of the shielding member abuts on the floor surface, the lower end of the shielding member can be brought into surface contact with the floor surface in a stable posture. Therefore, when this configuration is adopted, it is possible to further prevent articles from entering the lower side of the support structure. In addition, since the hollow cross section can be bent over a wide range of the peripheral area and the lower end can be brought into contact with the floor surface, it is also advantageous in terms of durability performance, and the ability to restrict the entry of articles can be maintained over a long period of time. be able to.

The shielding member may further include a fixed portion that is fixed to the support structure.

In this case, it becomes possible to easily fix the shielding member with the hollow cross-section to the support structure.

The shielding member includes the hollow cross-sectional portion that contacts the floor surface, a front flange portion that extends forward in the seating direction from the upper portion of the hollow cross-sectional portion, and a rear flange portion that extends rearward in the seating direction from the upper portion of the hollow cross-sectional portion. and, the hollow cross-sectional portion, the front flange portion, and the rear flange portion of the shielding member are integrally formed of an elastic sheet material, and further, of the front flange portion and the rear flange portion, At least one may be fixed to the support structure.

In this case, the shielding member having a hollow cross section can be easily manufactured from an elastic sheet material with a high yield. In addition, when this configuration is adopted, at least one of the front and rear flanges and the rear flange of the hollow section is fixed to the lower surface of the support structure so that the hollow section in contact with the floor can be placed in a stable position. can be supported by the support structure. In this case, for example, the rear flange may be fixed to the lower surface of the support structure, and the front flange may be engaged with the upholstery of the chair. Moreover, when both the front flange portion and the rear flange portion are fixed to the lower surface of the support structure, the hollow cross-sectional portion can be more stably supported by the support structure.

The shielding member extends continuously in the width direction of the chair, and the grounding members are arranged at two positions spaced apart in the width direction of the chair on at least the lower surface of the main body portion in the seating direction. Displacement restricting portions that are engaged with the grounding members on the front side in the seating direction may be provided at two positions of the member that are spaced apart in the width direction of the chair.

In this case, if the two displacement regulating portions of the shielding member spaced apart in the width direction of the chair are engaged with the grounding members on the front side of the seating direction, a large load is locally applied to the shielding member from the floor surface when the chair is moved. is input, the separation of the shielding member from the structure main body is restricted by the grounding member. Therefore, when this configuration is adopted, it is possible to prevent the shielding member from coming off.

In the chair according to the present invention, since the shielding member arranged at the lower edge on the front side of the support structure follows the shape of the floor surface and comes into contact with the floor surface, it is possible to further prevent articles from entering the lower part of the support structure. can be reliably suppressed.

An embodiment of the present invention will be described below with reference to the drawings.
In the following description of the embodiment, the direction in which the front of the seated person's body faces when the user sits on the chair 1 in a normal posture is defined as the front, and the opposite side is defined as the rear. Also, the upper side in the vertical direction is the upper side, and the opposite side is the lower side. Regarding the chair 1, the direction orthogonal to the front-rear direction and the up-down direction is called the "chair width direction", the left side toward the front of the chair 1 is the "left", and the right side toward the front of the chair 1 is "left". The side that becomes is called the "right".
An arrow FR pointing to the front of the chair 1, an arrow UP pointing to the upper side of the chair 1, and an arrow LH pointing to the left side of the chair 1 are indicated at appropriate places in the drawing.

FIG. 1 is a perspective view of the chair 1 of the embodiment viewed from above the right front portion. 2 is a view of the right lower area of the chair 1 from the front and FIG. 3 is a view of the right front area of the chair 1 from below.
The chair 1 of this embodiment is a sofa-type chair having a seat surface 2a that is long in the width direction of the chair. A chair 1 includes a seat part 2 on which a user sits, and a backrest part 3 for supporting the waist and back of the user from behind when the user is seated.

The seating part 2 and the backrest part 3 are provided with a cushioning material (not shown) attached to the outside of a skeleton base material (not shown) made of wood or the like, and the outside of the skeleton base material and the cushioning material is made of cloth, leather, or the like. It is covered with a skin material 4 . A wooden support structure 5 (see FIG. 3) for supporting the seat 2 is arranged below the seat 2 . The support structure 5 may be a structure separate from the frame base material of the seat portion 2, or may be a structure integrated therewith.

The support structure 5 includes a structure body portion 5A that supports the seat portion 2, and four grounding members 6 that are attached to the lower portion of the structure body portion 5A and have their lower ends grounded on the floor surface F.
In the present embodiment, the skin material 4 covering the outer sides of the seat portion 2 and the backrest portion 3 extends to the structure body portion 5A of the support structure 5, and the front surface, the rear surface, and the surface of the structure body portion 5A. Left and right side surfaces are covered with a skin material 4. - 特許庁The skin material 4 covering the periphery of the structure main body 5A is bent toward the lower surface side of the structure main body 5A and fixed to the peripheral portion of the lower surface of the structure main body 5A by a tucker or the like.

The structure body portion 5A is formed in a rectangular shape elongated in the width direction of the chair when viewed from below. In the vicinity of the four corners of the lower surface of the structure main body 5A, grounding members 6 whose lower ends are in contact with the floor surface F are attached by screwing or the like. The grounding member 6 is composed of, for example, a support leg having a short height dimension in the vertical direction. However, the grounding member 6 is not limited to a support leg having a fixed length, and may be a support leg whose height is adjustable. Furthermore, the grounding member 6 may be a caster that can roll on the floor surface F.
When the grounding member 6 attached to the square of the structural main body portion 5A5 is grounded on the floor surface F, a space S with a narrow vertical width is formed between the floor surface F and the lower surface 5a of the structural main body portion 5A. Form.

A shielding member covering the front side of the space S between the floor surface F and the lower surface 5a of the structure main body 5A is provided on the front edge of the lower surface 5a of the structure main body 5A (lower edge on the front side in the seating direction). 10 is attached. The shielding member 10 extends continuously in the chair width direction along the front edge of the structure main body 5A. The shielding member 10 extends from the vicinity of one end in the width direction of the chair to the vicinity of the other end, and also covers the front of the left and right ground contact members 6 arranged near the left and right corners on the front side.

FIG. 4 is a cross-sectional view taken along line IV-IV of FIG.
For example, as shown in FIG. 4, the shielding member 10 is formed of two layers of sheet materials 11a and 11b joined together. The back sheet material 11a is made of, for example, PVC leather (synthetic leather whose surface is coated with polyvinyl chloride), and the front sheet material 11b is made of, for example, an anti-slip urethane sheet. The front and back sheet materials 11a and 11b are joined together.
Note that the sheet material does not necessarily have to be two layers, and may be one layer or three or more layers.

The sheet materials 11a and 11b are cut into strips having a longitudinal length slightly shorter than the width of the structure main body 5A (the width in the width direction of the chair). The short sides of the sheet materials 11a and 11b cut in this way are curved into a substantially U shape, and the root side of the U shape is sewn close to each other to form a hollow cross-sectional portion 12 in the center of the short side direction. be. At this time, flange portions 13f and 13r are formed on both sides of the hollow section portion 12 in the lateral direction. The shielding member 10 is thus formed in a shape in which the hollow cross-sectional portion 12 and the flange portions 13f and 13r are continuous in the longitudinal direction. The shielding member 10 has one flange portion 13f fixed to the lower surface 5a of the structure body portion 5A on the front side of the hollow cross-section portion 12 so that the hollow cross-section portion 12 bulges downward, and the other flange portion 13r is hollow. It is fixed to the lower surface of the structure body portion 5A on the rear side of the cross section portion 12 . Each of the flange portions 13f and 13r is fixed to the lower surface 5a of the structure body portion 5A by, for example, Tucker. The shielding member 10 is fixed to the lower surface 5a of the structural main body 5A so that the hollow cross-sectional portion 12 extends in the chair width direction along the front edge of the structural main body 5A.
In addition, reference numeral 14 in FIG. 4 denotes a sewing thread for sewing the base portion of the hollow section portion 12, and 15 denotes a tucker needle for fixing the flange portions 13f and 13r to the lower surface 5a of the support structure 5. . Further, in this embodiment, one flange portion 13f constitutes a front flange portion, and the other flange portion 13r constitutes a rear flange portion.
In this embodiment, the front and rear flanges 13f and 13r of the shielding member 10 are fixed to the lower surface 5a of the structure main body 5A by Tucker or the like. It may be fixed to the lower surface of the main body portion 5A and the front flange portion 13f may be joined to the upholstery material 4. FIG.

In the shielding member 10 configured as described above, the hollow cross-sectional portion 12 is elastically deformable. When the chair 1 is placed on the floor surface F via the grounding member 6 with the shielding member 10 attached to the lower surface 5a of the structure main body 5A, the hollow cross section 12 is formed as shown in FIG. , it is set to contact the floor surface F and elastically deform. That is, the downward bulging dimension of the hollow cross-sectional portion 12 is set to a dimension that protrudes downward from the lower end of the grounding member 6 when there is no floor surface F. As shown in FIG. Therefore, when the chair 1 is placed on the floor surface F with the grounding member 6 interposed therebetween, the hollow section portion 12 is elastically deformed by coming into contact with the floor surface F. As shown in FIG. As a result, the hollow cross-sectional portion 12 of the shielding member 10 follows the shape of the floor surface F, and presses the lower surface thereof onto the floor surface F due to the elastic reaction force accompanying the deformation.
In addition, in the present embodiment, the cross section of the hollow cross-sectional portion 12 (the cross section crossing the longitudinal direction) is formed in an annular shape, but the cross-sectional shape of the hollow cross-sectional portion 12 is not limited to an annular shape. The cross-sectional shape of the hollow cross-sectional portion 12 may be, for example, U-shaped (C-shaped) or J-shaped.

Further, the rear flange portion 13r of the shielding member 10 extends to a position overlapping the attachment portions of the two front grounding members 6. As shown in FIG. Through holes 16 (see FIG. 3) through which the installation shaft of the grounding member 6 is inserted are formed in the vicinity of both ends of the flange portion 13r in the chair width direction. The mounting shafts of the left and right corresponding ground contact members 6 are inserted through the through holes 16 of the flange portion 13r. Displacement (positional deviation) of the peripheral portion of the through hole 16 is restricted. Specifically, when the grounding member 6 is fixed to the lower surface of the structural body portion 5A with the installation shaft of the grounding member 6 passing through the through hole 16, the peripheral edge portion of each through hole 16 in the flange portion 13r is is sandwiched between the peripheral portion on the upper surface side of the grounding member 6 and the lower surface of the structure main body portion 5A. As a result, displacement of a wide range around each through-hole 16 is regulated.
In this implementation process, the through hole 16 of the flange portion 13r and its peripheral edge constitute the displacement restricting portion of the shielding member 10. As shown in FIG.

As described above, in the chair 1 of the present embodiment, the shielding member 10 is arranged in the front part of the support structure 5 (structure body portion 5A), and the lower end of the shielding member 10 (lower region of the hollow cross-sectional portion 12) is It has a structure that can be deformed following the floor surface F (deformed according to the distance between the structure main body 5A and the floor surface F). Therefore, even if the floor surface F has some unevenness, when the chair 1 is placed on the floor surface F, the lower end of the shielding member 10 surely abuts on the floor surface F, and the floor surface F and the shielding member 10 are in contact with each other. It becomes difficult to create a gap between Therefore, even if a thin article such as a card tries to enter below the support structure 5 from the front side of the chair 1, the shielding member 10 reliably prevents the entry.

In the chair 1 of this embodiment, the support structure 5 is arranged below the structure main body 5A that supports the seating part 2 and the structure main body 5A, and is in contact with the floor surface F so as to be in contact with the floor surface F and the structure. and a grounding member 6 that forms a space S between the body main body portions 5A. In the case of this configuration, since the separate grounding member 6 is attached to the lower portion of the structure main body portion 5A of the support structure 5, the height of the grounding member 6 and the ground contact surface are adjusted to allow the support structure 5 to be positioned on the floor surface F. Stability can be easily increased.

In addition, the chair 1 of this embodiment employs the shielding member 10 made of an elastic member. Therefore, when the chair 1 is placed on the floor surface F, the lower end of the shielding member 10 is pressed onto the floor surface F by the elasticity of the member. Therefore, even if the floor surface F has some unevenness, a gap is less likely to occur between the floor surface F and the shielding member 10 . Therefore, when this configuration is employed, it is possible to more reliably prevent thin articles from entering below the support structure 5 .

Moreover, the chair 1 of this embodiment has a shape in which the shielding member 10 continuously extends in the width direction of the chair along the front edge of the structure main body 5A. Therefore, when the chair 1 is placed on the floor surface F, the lower end of the shielding member 10 comes into contact with the floor surface F without interruption in the width direction of the chair. Therefore, when this configuration is adopted, it is possible to further suppress the intrusion of articles below the support structure 5 .

In addition, the chair 1 of this embodiment employs the shielding member 10 having a structure in which the elastically deformable hollow cross-sectional portion 12 continuously extends in the width direction of the chair. Therefore, when the chair 1 is placed on the floor surface F, the shielding member 10 contacts the floor surface F at the lower end portion of the hollow section portion 12, and the lower end of the shielding member 10 faces the floor surface F in a stable posture. come into contact. Therefore, when this configuration is adopted, it is possible to further suppress the intrusion of articles below the support structure 5 .
Further, when this configuration is adopted, the hollow cross-sectional portion 12 of the shielding member 10 bends over a wide range of the peripheral area and presses the lower end portion onto the floor surface F, so that a part of the shielding member 10 It becomes difficult for a local load to act, and the durability of the shielding member 10 increases.

In addition, in the chair 1 of this embodiment, the shielding member 10 has the hollow cross-sectional portion 12 and the flange portions 13f and 13r which are fixed portions, and the flange portions 13f and 13r are fixed to the structure body portion 5A. . Therefore, when this configuration is adopted, the shielding member 10 having the hollow cross-sectional portion 12 can be easily fixed to the structure body portion 5A.

Further, in the chair 1 of this embodiment, the shielding member 10 has a hollow cross-sectional portion 12 and flange portions 13f and 13r, and these hollow cross-sectional portion 12 and flange portions 13f and 13r are elastic sheet members 11a and 11b. integrally formed by Therefore, when this configuration is employed, the shielding member 10 having the hollow cross-sectional portion 12 can be easily manufactured from the elastic sheet materials 11a and 11b with a high yield.
Further, when this configuration is adopted, by fixing the front and rear flanges 13a and 13b of the hollow section 12 to the lower surface of the support structure 5, the hollow section 12 in contact with the floor surface F is supported in a stable posture. It can be supported by the structure 5 . As a result, it is possible to further prevent articles from entering the lower side of the support structure 5 .
Only one of the flange portions 13f and 13r may be fixed to the structure body portion 5A. For example, the rear flange portion 13r may be fixed to the lower surface of the support structure 5A, and the front flange portion 13f may be joined to the upholstery 4 of the chair 1. FIG. In this case also, the hollow cross-sectional portion 12 of the shielding member 10 can be supported by the structure body portion 5A in a stable posture.

Further, in the chair 1 of the present embodiment, through holes 16 (displacement restricting portions) that are engaged with the ground members 6 on the front side are provided at two positions of the flange portion 13r of the shielding member 10 that are spaced apart in the chair width direction. are provided respectively. Therefore, even if a large local load is input to the shielding member 10 from the floor surface F when the chair 1 is moved, the separation of the shielding member 10 from the support structure 5 is prevented by the through hole 16. is regulated by locking by the grounding member 6 of the . Therefore, when this configuration is adopted, it is possible to prevent the shielding member 10 from coming off.
