Description

The present invention relates to a table and a leg device used therefor, and particularly to a table and its leg device that are used independently or used by connecting a plurality of units.

Most tables have a structure in which the top plate is supported by rod-like legs, and the shape in plan view is often rectangular. Then, when two tables are arranged side by side or back to back, adjacent top plates are connected with metal fittings. For example, two rectangular tables that can be seated one by one on each side are connected to the left and right to form a rectangular table that can be used by three people facing each other.

  In this way, when two tables are connected, there is a problem that the legs in the vicinity of the abutting portion in adjacent tables are likely to hit the user's foot. A leg positioned near one side (abutting side) constituting the contact portion is shifted to the back side of the table. For example, Patent Document 1 discloses that the leg device is shifted and moved to the inside of the table along the abutting side of the top plate in the plane view as it is, and is fixed with screws (bolts) in that state. Therefore, on the lower surface of the top plate, there are a group of screw holes for fixing the leg device to the outer position (first leg mounting portion), and a screw hole group for fixing the leg device to the inner position (second leg mounting portion). Is formed in advance.

  The leg device of Patent Document 1 has a structure in which a top plate support portion having a large area is provided on the upper end of a leg body that is long in the vertical direction. It is in a posture that protrudes from the center of the main body toward the diagonal direction of the top board. Therefore, in a state where the leg device is arranged at the outer position (first leg mounting portion), the top plate support portion having a large area can be firmly fixed to the top plate while the leg body is positioned as close to the outside of the top plate as possible. It can be said that the stability when the tables are used independently without being connected can be improved.

Japanese Patent No. 4204819 (Japanese Patent Laid-Open No. 2004-57345)

  Now, if the leg device is provided with a wide area top plate support part (bracket) as in Patent Document 1, the support strength is obtained when the leg device is arranged at the inner position (first leg attachment part) to connect the tables. In this aspect, it is preferable that the fixing position of the top plate support portion is as close to the outside of the top plate as possible. That is, when connecting the tables, the two front and rear leg devices are arranged along the abutting side of the top plate, but the support strength is to increase the distance between the top plate support portions of the front and rear leg devices as much as possible. It is preferable in terms of securing.

  However, in Patent Document 1, the leg device is merely shifted to the outer position and the inner position in the same posture, and in the state where the leg device is in the outer position, the top plate support portion is closer to the abutment side of the top plate than the leg body. Since the top plate support part is located on the inner side along the abutment side of the top plate than the leg body, the support strength surface is maintained. There was a risk that it would be hard to say.

  The present invention has been made to improve the current situation.

In a state where the leg device is in the inner position, the first reinforcing frame is used, and the engaging portion provided at the end of the bracket overlaps the end of the first reinforcing frame from below so that they are screwed to the top. When the leg device is in the outer position, the second reinforcing frame is used, and the engaging portion provided at the end of the bracket is placed on the end of the second reinforcing frame from below. It is set so that they overlap and are fastened together with the top plate with screws.

  According to a second aspect of the present invention, in the first aspect, when the leg device is at the outer position, a line connecting the center of the leg main body and the center of the bracket in a plan view is substantially the same as the diagonal direction of the top plate. The leg view posture of the leg device when it is in the inner position is a state in which the plan view posture of the leg device when it is at the outer position is horizontally turned by approximately 90 °.

The invention of claim 3 is provided with a top plate having a square shape in plan view having four corner portions and four leg devices for supporting the top plate at each corner portion, and a plurality of units can be connected to the left and right. Regarding the table. The leg device includes a leg body that is vertically long and a bracket provided at an upper end of the leg device, and the bracket is a square in plan view having four corner portions, While the screw holes penetrating vertically are formed in the corner portion at equal intervals in the circumferential direction, the leg main body is located at an outer position of the bracket in a plan view and extends in one diagonal direction in the bracket. The position of the leg body changes back and forth with respect to the axis of the bracket when the bracket of the leg device is horizontally rotated 90 ° in plan view to change the mounting position on the top plate. It is supposed to be.

According to a fourth aspect of the present invention, there is provided a leg device used in a table having a top plate having a rectangular shape in plan view and capable of connecting a plurality of units to the left and right. The configuration of the leg device is the same as that of the third aspect.

In the present invention, in addition to the top plate being reinforced by the reinforcing frame, the bracket of the leg device and the engaging portion of the reinforcing frame, both when the leg device is in the outer position and when it is in the inner position, Since the top plate is fastened together with the top plate, the unity of the top plate, the reinforcing frame, and the leg device is improved, and the strength can be further improved.
In addition, when the leg device is replaced between the outer position and the inner position, the bracket is positioned inside the leg column at the outer position and the bracket is positioned outside the leg column at the inner position. because the posture is that river so, when the leg support post at the inside position to assume the same position as Patent Document 1, the bracket is positioned outside the case of Patent Document 1, and therefore, the top plate The support strength of the bracket can be improved (the support strength is high because the interval between the brackets arranged back and forth along the contact side can be increased).

When employing the configuration according to claim 2, while the brackets to as large an area as possible, the bracket is prevented from protruding to the outside of the top plate, it can be brought close to the outer edge of the corner as possible top plate leg body. Thus, while increasing the fixing strength of the bracket can be lapping the corners of the end of the leg body, (when used independently a table) when the leg device is in the outward position further in supporting strength improvement of the top plate Can contribute. In addition, even if the leg device is horizontally rotated by about 90 ° from the posture when it is in the outer position, the bracket is not exposed to the outer side of the top plate. Therefore, the leg device is arranged at the inner position (the table is connected). Will not be disturbed.

(3) Summary of Embodiment As described above, when the table 1 is used independently as a single unit, the leg device 1 is arranged at an outer position close to the corner of the top plate 2 so that high support stability is achieved. Can be secured. In particular, when the leg body 4 and the bracket 5 (support portion 9) are formed in a square shape in plan view as in the embodiment, the leg body 4 is filled with the corners of the top board 2 while the bracket 5 is hidden on the lower surface of the top board 2. Therefore, higher support stability can be secured.

When the support span of the leg body 4 is increased , the bending moment acting on the top plate 2 is also increased. However, when the reinforcing frames 26 and 27 are provided as in the present embodiment, the rigidity of the top plate 2 is improved and high strength is obtained. There is an advantage that can be secured. Further, the bracket 5 of the leg 3 is may simply be fastened to the top plate 2 at the even inner position outward position, as in the present embodiment, the top plate 2 the ends of the reinforcing frame 26, 27 in both position When tightened together, the unity between the bracket 5 and the reinforcing frames 26 and 27 is ensured, resulting in a more robust structure.

  The first reinforcing frame 26 has a function of reinforcing the top plate 2, but it is preferable to bring the first reinforcing frame 26 as close as possible to the outer side 2 b of the top plate 2 in terms of securing the reinforcing function. On the other hand, the leg device 3 is shifted to the inner position so as not to obstruct the user's foot. Therefore, in the state where the leg device 3 is disposed at the inner position, the leg body 4 is attached to the top plate 2. It is preferable that it is located inside the outer side 2b as much as possible while ensuring stability.

  If the bracket 5 is fixed to the first reinforcing frame 26 in a state where the leg device 3 is merely shifted from the outer position along the contact side 2a without changing its posture, the leg body 4 is attached to the first reinforcing frame 26. Since it is located on the near side (side closer to the outer side 2b), there arises a problem that the leg body 4 is likely to hit the user's foot. That is, the function of improving the reinforcing function of the top plate 2 by bringing the first reinforcing frame 26 to the outside, and the leg main body 4 positioned as far as possible (back side) when the table 1 is connected to obstruct the human foot. There is a conflict with the function that prevents it from happening.

On the other hand, in the present embodiment, when the leg device 3 is arranged at the inner position, the leg main body 4 is positioned at the front and rear inner side than the bracket 5, so that the leg main body 4 can be moved as far as possible without moving the first reinforcing frame 26 too far. Since it can arrange | position inside (back side), as a result, the reinforcement function of the top plate 2 and the user's foot contact prevention function can be made compatible. This is one of the advantages of this embodiment.

Further, as shown in FIG. 3 (A), the fitting hole 31 of the first reinforcing frame 26, than the fitting hole 31 of the second reinforcing frame 27, the second reinforcing frame on the opposite side of the Tosehhen 2a 27 Therefore, when the leg device 3 is disposed at the inner position, the leg main body 4 is opposite to the abutting side 2a by the width dimension of the second reinforcing frame 27 than when it is at the outer position. The distance dimension W2 between the leg bodies 4 in the adjacent tables 1 is larger than the distance dimension when the leg device 3 is disposed at the outer position. For this reason, the bending span strength of the top plate 2 can be improved by reducing the support span in the direction of the outer side 2b.

(4). Second Embodiment FIG. 9 shows a second embodiment which is a modification of the bracket 5 and the reinforcing frames 26 and 27. This embodiment is different from the first embodiment only in the engagement portion 17 of the bracket 5, and the other configuration is the same as that of the first embodiment.

That is, in this embodiment, the engaging portion 17 of the bracket 5 has a configuration in which the intermediate plate 42 is provided at the intermediate height position, and the boss portions 43 protrude from the upper and lower sides of the intermediate plate 42. A slit groove 44 that fits into the intermediate plate 42 is formed at the ends of 26 and 27. The boss portion 43 enters the reinforcement frames 26 and 27. The upper and lower inner surfaces of the slit groove 44 and the intermediate plate 42 may be in contact with each other or may not be in contact with each other.

  In the embodiment of (A), the slit groove 44 is formed in each of the two side plates of the reinforcing frames 26 and 27. However, in the example shown in (B), only one side plate of the reinforcing frames 26 and 27 is provided. A notch groove 44 is formed. Therefore, in the example of (B), the intermediate plate 42 is stepped down from the outer surface of the support portion 9 by the thickness of the reinforcing frames 26 and 27 in plan view. In any case, in the embodiment of FIG. 9, it can be said that the boss portion 43 is sandwiched between the upper and lower plates of the reinforcing frames 26 and 27, and thus is excellent in strength.

(5). Others present invention can be in addition to various concrete than the above embodiment. For example, the top plate need not be square, but may be rectangular. When the top plate is rectangular, two connection modes can be selected: a mode in which the short sides are brought into contact with each other and a mode in which the long sides are brought into contact with each other.

The specific shape and structure of the leg device can also be set arbitrarily. For example, the bracket and the leg main body can be integrated, and conversely, one or both of the leg main body and the bracket can be formed of a plurality of members. It is also possible to set the leg body to a circle and the bracket 5 to a square such as a square.

Also, if the length of the long table rectangular, it is also possible to position provided a fixed intermediate leg. As the hollow rectangular reinforcing frame, channel steel having a C-shaped cross section can also be used.

The present invention can be embodied in a table. Therefore, it can be used industrially.
