Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a chair (ganging chair) that can be connected to left and right.
[0002]
[Prior art]
For example, a chair installed in a conference room or the like can be connected to left and right. Conventionally, the purpose of connecting chairs to the left and right is to hold a large number of chairs arranged in a line, and as a connection structure, seats are connected to each other or legs are connected to each other.
[0003]
In addition to being able to connect chairs, in order to make effective use of the storage space when storing in a warehouse, etc., multiple chairs can be stacked vertically (stacked vertically) or fitted back and forth. In some cases, they can be overlapped (horizontal stacking) in a state where they are placed.
[0004]
The conventional connectable chair is based on the premise that one person can use one chair even in a connected state, and therefore, the seat body and the backrest have a structure that matches the curved surface of the human body. In most cases, the chairs are set so that there is a slight gap between the side surfaces of the chairs adjacent to each other in a connected state.
[0005]
[Problems to be solved by the invention]
By the way, the size of a person's body is various. In some chairs, there is still room for sitting space.
[0006]
In addition, even in the case of a normal physique, there are cases where it is desired to sit at a certain distance from a neighbor, or, conversely, to sit with their shoulders close together.
[0007]
However, the conventional articulated chair is based on the premise that one person sits in one chair even in the articulated state, that is, a person sits down while straddling an adjacent chair. Since it is impossible to do so, there is a problem that it is not possible to respond to the difference in the user's physique and the difference in the demand for the use mode. That is, there was a problem that the conventional chair was inflexible.
[0008]
An object of the present invention is to improve such a situation.
[0009]
[Means for Solving the Problems]
In the chair according to the first aspect of the present invention, there is provided a connecting means which can be arranged side by side in a state in which at least the seats of the seats or the backrests are integrally continuous, and which can be held in the left and right side by side. Providing this makes it possible for a person to sit on the chair while straddling two chairs arranged side by side.
[0010]
According to a second aspect of the present invention, there is provided the chair according to the first aspect, wherein the chair includes a leg, a seat, and a backrest, and can be connected in a state where the seats and the backrests are integrally arranged in a row. Therefore, a plurality of chairs are allowed to be stacked in a vertically fitted state, or are allowed to be horizontally overlapped in a state of being fitted back and forth.
[0011]
According to a third aspect of the present invention, in the second aspect, the seat body is formed in a square shape in plan view, and the backrest is formed in a square shape in front view, and the left and right side surfaces of the seat body and the backrest extend linearly in plan view. This arrangement allows a plurality of chairs to be arranged side by side with the left and right sides of the seat body and the left and right sides of the backrest overlapping each other.
[0012]
On the other hand, the leg is provided with four front and rear and right and left independent legs extending downward from the lower surface of the seat body, and these independent legs are inclined in a C shape in a side view, and further, only the seat body or By providing a hole through which each leg of the upper chair passes when a plurality of chairs are arranged vertically on the seat body and the backrest, it is possible to stack the plurality of chairs in a state of being fitted up and down. .
[0013]
According to a fourth aspect of the present invention, in the second aspect, the seat body is formed in a square shape in plan view, and the backrest is formed in a square shape in front view, and the left and right side surfaces of the seat body and the backrest extend linearly in plan view. The seats are allowed to be arranged side by side so that the left and right sides of the seat and the left and right sides of the backrest overlap each other, and the seat is flipped up and down so as to overlap with the backrest. It is free to move.
[0014]
On the other hand, the legs are formed in a metal pipe in the shape of a mountain in a side view when viewed from the side, and the left and right legs are arranged in a plan view such that the left-right space between the front ends is narrower than the left-right space between the rear ends. By tilting the seat body up and rotating by inclining in a reverse C-shape, a plurality of chairs can be overlapped in a state of being fitted back and forth.
[0015]
[Action and Effect of the Invention]
The chair of the present invention is similar to a bench when a plurality of chairs are connected, and a person can sit on any part of the connected chair group. For example, three chair groups can be replaced by four small people. Versatile use depending on the physique of the user, regardless of the number of connected chairs, such as the use of three chair groups by two large people equally An embodiment can be selected.
[0016]
Therefore, according to the present invention, it is possible to provide a highly versatile chair capable of selecting a use mode according to a user's request in a connected state while ensuring independent use.
[0017]
When configured as in claims 2 to 4, a plurality of chairs can be overlapped in the vertical direction (up and down direction) or in the horizontal direction in a state where they are fitted to each other, and are stored in a warehouse or the like when not in use. In this case, there is an advantage that the space can be effectively used.
[0018]
Further, it is more preferable that the backrests are integrally connected to each other as described in claim 2, because when sitting on two chairs adjacent to each other, a sense of discomfort to the back can be eliminated. .
[0019]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings.
[0020]
(1). First embodiment (FIGS. 1 to 5)
1 to 5 show a first embodiment. 1 (A) is a perspective view in a state of being juxtaposed, FIG. 1 (B) is a sectional view taken along line BB of FIG. 1 (A), FIG. 2 (A) is a plan view, FIG. (C) is a cross-sectional view taken along line CC of (B), and FIG. 3 is a cross-sectional view of a stacked state.
[0021]
▲ 1 ▼. The basic structure and the stacking chair 1 are provided with a seat 2 having a substantially right-angled quadrilateral in plan view, a backrest 3 also having a substantially right-angled quadrilateral in front view, and a leg 4 made of a pipe. The seat body 2 and the backrest 3 are formed in a shell shape by a synthetic resin, and both are integrally continuous (of course, the seat body 2 and the backrest 3 may be separate bodies).
[0022]
The upper surface of the seat body 2 and the front surface of the backrest 3 are substantially flat, and the side plate 2a of the seat body 2 and the side plate 3a of the backrest 3 are linearly continuous in a front view and a plan view. Therefore, the chairs 1 can be arranged side by side with the upper surface of the seat body 2 and the front surface of the backrest 3 continuing in the same plane. It is preferable that both the seat body 2 and the backrest 3 have a rigid structure that does not bend and deform even when a person sits. It is also possible to put a cushion on the seat body 2 and the backrest 3.
[0023]
The upper surface of the seat body 2 and the front surface of the backrest 3 do not necessarily have to be formed as flat surfaces. For example, in the case of the seat body 2, it is not possible to form the seat body upwardly concave in side view so as to fit the buttocks of a seated person. No problem. However, even in this case, it should be formed so that the upward concave state is continuous over the entire left and right length.
[0024]
That is, the upper surface of the seat body 2 should have substantially the same profile over the entire length in the left and right directions, so that a person can sit in a connected state without straddling two adjacent chairs 1 without discomfort. Can be.
[0025]
Similarly, the front surface of the backrest 3 may be curved in a forwardly convex shape or a forwardly concave shape in a side view, but its profile is preferably continuous over the entire left and right length. That is, both the upper surface of the seat plate 2 and the front surface of the backrest 3 should be formed so as to extend substantially linearly in the left-right direction at an arbitrary front-rear position.
[0026]
The leg 4 is made of a metal pipe such as steel or aluminum, and has four independent legs 5 for front, rear, left and right. The upper ends of the front and rear independent legs 5 are integrally continuous by a horizontal portion 6. The left and right horizontal portions 6 are connected by a reinforcing stay 7. The seat 2 is fixed to the horizontal portion 6 and the stay 7 by various means such as screwing.
[0027]
The front two of the independent legs 5 are inclined backward in a side view, and the rear two are inclined forward in a side view. It has a C-shape when viewed from the side. The rear independent leg 5 extends so that its lower part partially overlaps with the backrest 3 in plan view (to increase stability).
[0028]
The seat body 2 and the backrest 3 each have a pair of front and rear long holes 8 extending in the front-rear direction so that the independent legs 5 are fitted with some margin and extend in the front-rear direction so as to overlap with the independent legs 5 in plan view. It is empty.
[0029]
As shown in FIG. 3, the independent legs 5 are inclined in the side view, and the elongated holes 8 are formed in the seat body 2 and the backrest 3, as shown in FIG. 3. By fitting the independent legs 5 into the long holes 8 of the chairs located at the lower tier, a large number of chairs 1 can be vertically stacked in a state of being fitted up and down. That is, stacking can be performed in the vertical direction.
[0030]
The reason why the rear elongated hole 8 extends to the backrest 3 is that, as described above, the lower end of the rear independent leg 5 extends rearward so as to overlap the backrest 3 in a plan view. When the leg 5 overlaps only with the seat 2 in plan view, the elongated hole 8 may be provided only in the seat 2.
[0031]
Each independent leg 5 may be inclined in a C-shape when viewed from the front (in this case, the elongated hole 8 extends long in the left-right direction), and the four independent legs 5 are formed in both a front view and a side view. It may be inclined so as to form a letter shape (in this case, the long hole 8 extends long in the radial direction in plan view).
[0032]
▲ 2 ▼. FIG. 4 shows an example of the connecting means for holding the connecting means chairs 1 in a state of being arranged side by side. 4, (A) is an isolated cross-sectional view, (B) is a BB view of (A), (C) is a CC view of (A), and (D) is a D- view of (A). FIG. D is a vertical cross-sectional view of the connected state.
[0033]
In this embodiment, one side plate 2a, 3a of the seat body 2 and the backrest 3 is provided with a headed pin portion 9 which forms a part of the engagement means in a lateral direction, while the other of the seat body 2 and the backrest 3 is provided. The side plates 2b and 3b are also formed with an engagement groove 10 having a downward opening which is fitted into the pin portion 9 from above as a part of the engagement means.
[0034]
Therefore, by lifting one chair 1 and dropping its engaging groove 10 into the pin portion 9 of the other chair 1 and engaging it, the adjacent chairs 1 are held irreversibly in any of the front, rear, left and right directions. Is done. It is preferable that the lower part of the engaging groove 10 be expanded to be flared in order to easily fit the engaging groove 10 into the pin portion 9.
[0035]
The number of the pin portions 9 and the engagement grooves 10 can be set arbitrarily. However, when a plurality of the seat members 2 and the backrest 3 are provided, the group of the seat member 2 and the backrest 3 can be firmly connected. It can be said that it is preferable. Of course, in order to secure the basic function of connecting the chair 1, it is sufficient to provide only one place on either the seat 2 or the backrest 3.
[0036]
(3). When the chairs 1 are connected to each other left and right, the group of the seat body 2 and the group of the backrests 3 each have a plate shape, so that a person sits comfortably while straddling two adjacent chairs. can do. Therefore, it can be used in various modes. Some examples in that case are shown in FIG.
[0037]
5A shows a state in which each chair 1 is used by one person, and FIG. 5B shows a state in which one of the four connected chairs is used by one person and the other three are used. (C) is a diagram of a state in which two people with large physiques use four chairs, and (D) is a diagram of a state in which five people with small physiques (for example, children) equally use four chairs. The chairs 1 at the right and left ends are used by a person of normal physique (eg, parents), and each of the two chairs 1 located between the three chairs of small size (eg, children such as infants and children). FIG.
[0038]
Of course, it can be used in various other modes. For example, when the user is a giant, two chairs can be used alone.
[0039]
There is a case where a person sleeps on the connected chair group, and in this case, in the conventional chair, the upper surface of the group of the seat body 2 is mostly uneven in front view, so that the sleeping comfort is extremely poor as a rugged, In the present embodiment, since the group of the seats 2 extends linearly when viewed from the front, there is an advantage that the burden on the body can be reduced.
[0040]
(2). Second embodiment (FIG. 6)
FIG. 6 shows a second embodiment which is another example of the connecting means. (A) is an isolated cross-sectional view of a main part, and (B) is a plan view taken along line BB of (A).
[0041]
In the second embodiment, a plurality of split-type engaging claws 12 are protruded from one side plate 2a of the seat body 2 as a part of the engaging means, while the other side plate 2b is provided as a part of the engaging means. An engaging hole 13 is provided, and the chair 1 can be connected by fitting the engaging claw 12 into the engaging hole 13 against its elasticity.
[0042]
Needless to say, the engagement between the engagement claw 12 and the engagement hole 13 can be released by applying a certain amount of force and pulling. The engaging claws 12 and the engaging holes 13 are preferably provided also on the side plates 3a and 3b of the backrest 3.
[0043]
(3). Third and fourth embodiments (FIGS. 7 and 8)
The third embodiment shown in FIG. 7 is another example of the connecting means. (A) is an isolated sectional view of a main part, and (B) is a plan sectional view taken along line BB of (A).
[0044]
In the third embodiment, a movable engagement claw 14 that is vertically rotatable between a retracted position hidden inside the side plate 2a and a horizontal position projected outside the side plate 2a is provided inside one side plate 2a of the seat body 2. On the other hand, the other side plate 2b receives an engagement hole 15 into which a movable engagement claw 14 in a horizontal position can be fitted against elasticity. The movable engagement claw 14 is attached to the bracket 16 with a pin 17.
[0045]
The fourth embodiment shown in FIG. 8 is another example of the connecting means provided with the movable engagement claw 15 which is vertically movable. (A) is an isolated sectional view of a main part, and (B) is a plan sectional view taken along line BB of (A).
[0046]
In this embodiment, the movable engaging claw 15 is formed with a head so as to form a T-shape in a horizontal posture and a planar view, and the other side plate 2b faces downward so that the narrow portion of the movable engaging claw 15 is fitted. An opening engaging groove 18 is formed.
[0047]
7 and 8, since the movable engaging claw 14 can be hidden inside the side plate 2a when not in use, there is an advantage that it is possible to prevent a person's clothes or the like from being caught. In the embodiment of FIG. 8, there is an advantage that the connection and disconnection of the chairs can be easily performed only by lifting one of the chairs and fitting the engagement groove 18 into and out of the movable engagement claw 14.
[0048]
(4). Fifth to sixth embodiments (FIGS. 9 to 10)
As the connecting means, a connecting tool separate from the seat body 2 and the backrest 3 can be used.
[0049]
As an example, in the fifth embodiment shown in FIG. 9, engagement holes 19 are formed in the side plates 2 a and 2 b of the seat body 2 (and the backrest 3), and a plurality of split snap pins 20 are formed in the engagement holes 19. The chairs are connected by fitting the.
[0050]
On the other hand, in the sixth embodiment shown in FIG. 10, a connecting plate 21 is used as a connecting tool, and an engaging groove 22 in which the front and rear independent legs 5 of the adjacent chair 1 fits is opened on both left and right side edges. Has formed.
[0051]
In this case, while the front and rear independent legs 5 are inclined in a C-shaped posture as viewed from the side as in the first embodiment, the engagement grooves 22 are fitted into the horizontal openings 22a in the front and rear outward fitting portions. 22b are formed in an L shape in a plan view so as to be continuous.
[0052]
Further, since the front and rear independent legs 5 are inclined downwardly in a side view, when the lateral opening 22a is fitted into the front and rear independent legs 5 and the connecting plate 21 is shifted downward, the vertical fitting portion is formed. 22b is tightly fitted to the independent leg 5, and is held immovably by the connecting plate 21, the independent leg 5, and any of the front, rear, left, and right, so that the left and right chairs 1 can be connected immovably.
[0053]
(5). Seventh embodiment (FIG. 11)
FIG. 11 shows a seventh embodiment as another example of the means for enabling stacking in the vertical direction. (A) is a side view, (B) is a partial front view of (A). The connecting means is omitted.
[0054]
In this embodiment, the backrest 3 is configured to be rotatable so as to overlap with the seat body 2, while the front and rear independent legs 5 have a C-shape when viewed from the side, and the upper end thereof is a seat body. 2 are set at the front and rear edges. In this embodiment, when the backrest 3 is turned down, many chairs 1 can be stacked directly above.
[0055]
Each independent leg 5 is set so as not to protrude from the side surface of the seat body 2 so that the side surface of the seat body 2 in the adjacent chair 1 can be brought into close contact.
[0056]
(6). Eighth embodiment (FIGS. 12 to 15)
12 to 15 show an eighth embodiment. 12, (A) is a right side view, (B) is a partial cross-sectional view taken along line BB of (A), (C) is a cross-sectional view taken along line CC of (B), and (D) is a seat body 2. 13, FIG. 13 is a plan view, FIG. 14 is a front view, and FIG. 15 is a side view in a stacking state.
[0057]
In this embodiment, the horizontal portion 6 of the leg portion 4 has a very short dimension (there may be none), and the front independent leg 5 'in the forwardly inclined position and the rear unit leg 5 "in the rearwardly inclined position have large left and right legs. The seat 2 is attached to a bracket 24 projecting upward from the horizontal portion 6 with a pin 25 so that the seat 2 can be flipped up and rotated around its rear end.
[0058]
In addition, in the case where the seat body is flipped up in a chair in which the legs have a frame structure made of a pipe, the left and right unit legs are often arranged on the left and right outer sides of the seat body 2. In order to connect the chairs in close contact with each other, the left and right independent legs 5 ′ and 5 ″ must not protrude outside the side surface of the seat body 2. It is attached to the bracket 24.
[0059]
As shown in FIGS. 13 and 14, the leg portion 4 has an inverted C-shape in plan view so that the interval between the front ends is narrow and the interval between the rear ends is wide. The left and right front independent legs 5 ′ are connected to each other by a front stay 26 at a halfway height thereof, while a stopper 27, which corresponds to the front stay 26, protrudes downward from the seat body 2. The upper ends of the left and right rear independent legs 5 ″ are connected by a rear stay 28, and the backrest 3 is attached to a plurality of back columns 29 erected from the rear stay 28.
[0060]
In this embodiment, the front independent legs 5 'are greatly inclined rearward, and the legs 4 as a whole have an inverted U-shape in plan view. Therefore, as shown in FIG. When the body 2 is flipped up and rotated, a large number of chairs 1 can be overlapped in the horizontal direction in a state where the legs 4 are fitted to each other.
[0061]
In this embodiment, the connecting means is not shown, but at least one of the seats, the backrests, or the legs may be connected by various modes or other modes disclosed previously.
[0062]
As can be easily understood from the eighth embodiment, the seat body and the backrest do not need to be continuous, and a space may be provided between the rear end of the seat body and the lower end of the backrest. is there.
[0063]
(7). Ninth embodiment (FIG. 16)
FIG. 16 shows a ninth embodiment. (A) is a front view in a state of being arranged side by side in a row, and (B) is a BB view of (A).
[0064]
In this embodiment, the four independent legs 30 and 31 are formed to have a C-shaped posture in front view and side view, and the independent legs 30 and 31 are formed to protrude outside the seat body 2 in front view. Thus, a large number of chairs 1 can be stacked in the vertical direction.
[0065]
Furthermore, instead of disposing the independent legs 30, 31 symmetrically, the left independent leg 30 and the right independent leg 31 are shifted in the front-rear direction, so that the side surfaces of the seat body 2 are closely attached to each other. It is possible to arrange chairs side by side. Also in this case, the seat body 2 and the backrest 3 can be stacked in the vertical direction without impairing the function of being connected so as to be integrally continuous.
[0066]
(7). Tenth embodiment (FIGS. 17 and 18)
17 and 18 show a tenth embodiment. 17A is a schematic perspective view of the chair, FIG. 17B is a side view, and FIG. 18 is a partial front view showing a connected state.
[0067]
In this embodiment, the left and right legs 32, 33 are configured such that lower front and rear lower portions 32b, 33b are integrally connected to the lower ends of the front and rear standing portions 32a, 33a. The chair 1 is allowed to be stacked in the vertical direction by positioning the upper end of the seat 32 outside the seat body 2 and inclining the left and right legs 32 and 33 as a whole in a C-shape in a front view.
[0068]
The left and right legs 32, 33 are not formed symmetrically, but the front and rear widths of the left and right legs 32, 33 are different so that the other leg 33 can fit inside one leg 32. Therefore, as shown in FIG. 18B, the chairs 1 can be arranged side by side in a state where the side surfaces of the seat body 2 and the backrest 3 are overlapped.
[0069]
Further, a pair of front and rear first connectors 34 is fixed to the lower horizontal portion 32b of the leg portion (left leg portion) 32 having a wide front-rear interval, and the lower horizontal portion 33b of the leg (right leg) 33 having a narrow front-rear interval is provided. A pair of second connectors 35 located inside the first connector 34 are fixed.
[0070]
The first connecting member 34 protrudes outward, and an engagement groove 36 that can be fitted into the lower horizontal portion 33b from above is formed on the lower surface of the protruding portion, while the second connecting member 35 is An engagement groove 36 is formed on the lower surface of the inwardly protruding portion and can be fitted into the lower horizontal portion 32b from above.
[0071]
Therefore, as shown in FIG. 18A, in a state where the chairs are arranged side by side with a space between the side surfaces of the seat body 2, the first connecting body 34 is connected to the lower horizontal portion 33 b of the adjacent chair 1. By fitting, the chairs 1 can be held so as not to be displaced from front to back and left and right.
[0072]
Conversely, as shown in FIG. 18B, when the chairs 1 are arranged side by side with the side surfaces of the seat body 2 overlapped, the second connecting body 35 is fitted to the lower horizontal portion 32 b of the adjacent chair 1. By combining them, the two chairs 1 can be held so as not to be displaced in the front-rear and left-right directions.
[0073]
In this embodiment, one chair can be selectively connected to a mode used by only one person and a mode used by a different number of people than the number of chairs. Therefore, the variation of the usage mode in the connected state can be further enriched.
[0074]
In the present embodiment and other embodiments, when the seat body and the backrest 3 are arranged side by side so as to be continuous, when the backrest 3 is elastically deformed and can slightly tilt backward, the back of the seated person is adjacent. If the left and right backrests overlap at the joint of the combined backrests, there is a risk that the outer garment will be pinched by the backrests due to the displacement of the left and right backrests. It can be said that it is preferable to do so.
[0075]
(8). Others The present invention can be embodied in various ways other than the above-described embodiment. For example, the seat and the backrest are not limited to being made of synthetic resin, and various materials such as wood and plywood can be selected. It is also possible to make the seat and backrest perforated plates.
[0076]
The legs do not need to have the frame structure as in the embodiment, but may be, for example, a form in which radial branch rods are provided from pillars supporting the center of the seat body. A caster may be provided on the leg. The leg may be made of a rod, a sheet metal, or a synthetic resin, instead of being made of a pipe.
[0077]
Further, it is also possible to form the seat body in a trapezoidal shape in plan view so that a large number of chairs are connected in a state of being arranged in an arc shape in plan view. In this case, the width dimension of the front end of the seat body may be larger than the width dimension of the rear end, or vice versa.
[0078]
As the connecting means, it is needless to say that an engaging means different from that shown in the drawing may be provided on the chair itself, or a fastener different from the chair may be used.
