Description

chair{chair}

The present invention relates to a chair, and more specifically, the main body provided on the upper part of the leg portion on which the user sits is rotatable relative to the front so that the front and rear chairs can overlap and the leg portion supports both the front and rear of the main body portion. This relates to a chair that can increase durability by ensuring that the load is evenly distributed when the user sits.

In general, chairs are provided to enable people to maintain a seated state while performing work or study using a desk or table in various places, including homes, offices, schools, academies, libraries, and various public institutions.

The chair has a main body with a backrest formed on the rear of a seat on which the user sits, and a plurality of support legs are provided at the lower part of the main body so that the seat is installed at a certain height from the floor.

The chairs are manufactured and distributed in various sizes, shapes, and materials depending on the user using the chair, the place or purpose for which the chair is used, etc.

However, due to its nature, conventional chairs take up a lot of volume, and even when some parts are implemented in an assembleable form, there is a problem of low storage and transportation efficiency.

On the other hand, places where many people attend, such as school auditoriums, gyms, various event halls, and large conference rooms, require multiple chairs to match the number of users, and in such cases, it is difficult to store or transport multiple chairs. do.

In other words, due to the structure of conventional chairs, vertical stacking is mainly used to store a large number of chairs. As described above, vertically stacking multiple chairs inevitably requires a lot of labor and time, and in addition, A problem arose in that the stacking height was also very limited.

In addition, when a large number of chairs must be moved, a small number of chairs must be lifted and moved in a stacked state or each chair must be moved separately, resulting in a problem in which the efficiency of movement is greatly reduced.

So, in order to solve this problem, the technology described in Korean Patent No. 10-2057897 as shown in Figures 1 to 3 was proposed, the technical feature of which is that the seat plate 12 and the backrest 14 are formed as one piece. a main body (10); a horizontal bar 40 disposed horizontally on the lower side of the main body 10; a pair of rotating members 60, one pair of which is fixedly coupled to be parallel to the lower surface of the main body 10, and rotatable at a certain angle with respect to the horizontal bar 40; A pair of front support legs (20) made of a rod member of a certain length; A pair of rear support legs (30) made of a rod member of a certain length; It is configured to include a pair of connectors that are fixedly coupled to both ends of the horizontal bar (40) and on which one front support leg (20) and one rear support leg (30) are respectively mounted; The connector 50 is made in the form of a "┳" shaped tube, with a front insertion protrusion 54 inserted into the horizontal bar 40 at one end integrally coupled with the rear support leg 30 at the bottom. The coupling protrusion 52 on which the upper part is mounted is formed by being integrally coupled; A rear insertion protrusion 22 that penetrates the connector and is inserted into the inner peripheral surface of the front insertion protrusion 54 is formed to protrude at a point having a certain height of the front support leg 20.

However, the technology described in Korean Patent No. 10-2057897 forms the main body of the chair, including the seat and backrest, into a rotatable structure so that multiple chairs can be efficiently stored in a state where they are overlapped and closely attached to each other in the front and rear directions. There is an advantage, but there is a problem that the horizontal bar is formed to support only the front lower part of the seat plate, so the load is concentrated on the rear of the seat plate, causing the seat plate to bend backwards or, in severe cases, be damaged.

In addition, the horizontal bar portion through which the load applied to the rear of the seat is directly transmitted may also be damaged, resulting in low durability.

The same reference numerals are used for the same components in the drawings, and duplicate descriptions for the same components are omitted. Additionally, it should be understood that the present invention can be implemented in many different forms and is not limited to the described embodiments.

Figure 4 is a perspective view of the chair according to the present invention, Figure 5 is an exploded perspective view of the chair according to the present invention, Figure 6 is a side conceptual view of the chair according to the present invention, and Figure 7 is a coupling member of the chair according to the present invention. It is a conceptual diagram showing the coupling relationship of the front support bar, and Figure 8 is a side view of the main body of the chair according to the present invention in a rotated state.

The present invention relates to a chair, and as shown in FIGS. 4 to 8, the configuration includes a main body 100 consisting of a seat 110 on which the user sits and a backrest 120 that supports the user's back, and the main body part. It consists of a leg portion 200 supporting the lower part of the seat plate 100 and a coupling member 300 installed on the entire lower surface of the seat plate 110 and rotatably coupled to the entire leg portion 200.

Therefore, the front and rear chairs can overlap each other with the main body 100 rotated based on the coupling member 300, making it possible to store and transport multiple chairs in an overlapping state.

In addition, the leg portion 200 includes a pair of front legs 210 supporting the front, a pair of rear legs 220 supporting the rear, and upper portions of the front legs 210 and the rear legs 220. It consists of a connecting bar 230 that connects each.

Here, a front support bar 240 is installed on the upper part of the front leg 210 to support the entire lower surface of the seat plate 110, and on the upper part of the rear leg 220, it supports the rear lower surface of the seat plate 110. A rear support bar 250 is installed.

At this time, the connecting bar 230 is formed to slope downward toward the rear, and accordingly, the rear support bar 250 is formed at a lower height than the front support bar 210, and the gap 210 between the front legs is It is formed wider than the gap between the rear legs 220.

Therefore, when the front and rear chairs are overlapped with the main body 100 rotated, the rear legs 220 of the chair located in the front are inserted between the front legs 110 of the chair located in the rear, and the connecting bar Since 230 is formed to slope downward toward the rear, the leg portion 200 of the front chair can be completely inserted into the inner leg portion 200 of the rear chair.

Therefore, the chairs can be overlapped so that they are in close contact front and back, thereby significantly reducing the overall volume and making storage and transportation easier.

In addition, the coupling member 300 is installed on the entire lower surface of the seat plate 110 and is coupled to and supported by the front support bar 240, and is supported on the upper part of the rear support bar 250 on the rear lower surface of the seat plate 110. A rear support member 130 is installed as much as possible.

At this time, as shown in FIG. 6, the rear support member 130 has a height at which the coupling member 300 is supported on the front support bar 240 by the height difference between the front support bar 240 and the rear support bar 250. By forming it longer, the front and rear portions of the seat plate 110 are maintained in a horizontal state.

Therefore, in the present invention, while making it possible to overlap by rotating the main body 100, the front and rear of the seat 110 are supported by the front support bar 240 and the rear support bar 250, respectively, so that the load is maintained while the user is seated. Not only is it distributed evenly to increase durability, but the seat plate 110 is maintained in a horizontal state, allowing the user to sit on the chair in a stable state.

In other words, since the seat plate 12 is supported by the horizontal bar 40 in the conventional chair that can be overlapped as shown in FIG. 1, there is a problem in that the load is concentrated on the horizontal bar 40 and can be easily damaged. .

However, in the present invention, as described above, not only is it possible to overlap the chairs front and rear, but it is also possible to support the front and rear of the seat plate 110, respectively, so that the load applied when the user is seated is distributed to the front and rear, thereby providing a specific This prevents excessive load from being concentrated on the part and increases durability.

In addition, the coupling member 300 is installed on the entire lower surface of the seat plate 110 and is coupled to the upper member 310 into which the upper part of the front support bar 240 is inserted and the lower part of the upper member 310. It consists of a lower member 320 into which the lower part of the front support bar 240 is inserted. The lower surface of the upper member 310 has an upper receiving groove 312 along the longitudinal direction into which the upper part of the front support bar 240 is inserted. A lower receiving groove 322 is formed on the upper surface of the lower member 320 along the longitudinal direction into which the lower part of the front support bar 240 is inserted.

Here, first connection bar receiving grooves 324 into which the connection bar 230 is inserted are formed on both sides in the longitudinal direction of the lower member 320, and the connection bar ( A second connection bar receiving groove (not shown) is formed into which the upper part of 230) is inserted.

At this time, the first connecting bar receiving groove 324 is formed larger than the thickness of the connecting bar 230, and the depth of the first connecting bar receiving groove 324 corresponds to the angle at which the main body 100 is rotated. It is formed at a depth that becomes

Therefore, when the coupling member 300 rotatably installed on the front support bar 240 constituting the leg portion 200 rotates together with the main body portion 100, the first connection bar receiving groove 324 By supporting the connecting bar 230 at the end of the chair, the main body 100 is prevented from rotating any more, so that when the chairs are overlapped front and back, the rotation angle of the main body 100 is the same, allowing stable overlap.

Meanwhile, adjustment bars 242 are formed to protrude downward at the lower portions of both longitudinal sides of the front support bar 240, and adjustment holes 328 into which the adjustment bars 242 are inserted are formed on both longitudinal sides of the lower member 320. ) is formed.

Here, the adjustment hole 328 is formed in the shape of a long hole, so that when the main body 100 rotates, the adjustment bar 242 moves along the adjustment hole 328, and the adjustment hole 328 is as described above. Like the first connection bar receiving groove 324, it is formed in an arc shape corresponding to the angle at which the main body 100 is rotated.

Therefore, when the main body 100 rotates, the adjustment bar 242 is brought into contact with the end of the adjustment hole 328 to prevent the main body 100 from rotating excessively. By supporting the main body 100 in a rotated state, such as the connecting bar receiving groove 324 and the connecting bar 230, even if an external force acts, the applied force is transmitted through the first connecting bar receiving groove 324 and the adjustment hole ( 328) to prevent damage to the coupling member 300.

At this time, acetalib (not shown) is further provided on the outside of the adjustment bar 242 to reduce friction with the adjustment hole 328 and prevent noise generated during rotation.

In addition, a first damper bracket 244 is formed on the front support bar 240 to protrude rearward, and a second damper bracket 112 is formed on the lower surface of the seat plate 110, and the rotation of the seat plate 110 One end of the damper 260 that adjusts is hingedly coupled to the first damper bracket 244, and the other end of the damper 260 is connected to the second damper bracket 112.

Here, a bracket receiving groove 326 into which the first damper bracket 244 is inserted is formed in the lower member 320, and the depth of the bracket receiving groove 326 is determined by the angle at which the main body 100 is rotated. It is formed at a depth corresponding to .

Therefore, the damper 260 maintains the rotated state when the main body 100 rotates and maintains it stably even when the main body 100 returns to its original position.

At this time, as described above, when the main body 100 rotates, the first damper bracket 244 comes into contact with the inner end of the bracket receiving groove 326 and distributes the load when an external force is applied from the outside. This increases the durability of the coupling member 300.
