Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to furniture with legs such as tables and desks.

0002

[Conventional technology]

Conventionally, the periphery of the deck was surrounded by a frame, and support plates on which the deck was placed were placed at the corners of the frame. However, there are tables and the like having a structure in which legs are screwed to this support plate.

0003 Tables with this type of structure have the problem that the screws loosen and the legs easily come off. There is.

0004 Additionally, such tables have the problem of being difficult to use because the height of the deck cannot be adjusted. Ru.

[0005]

[Problem that the idea aims to solve]

Therefore, this invention is a table whose legs do not come off easily and whose deck height can be adjusted. The purpose is to provide furniture with legs such as desks.

[0006]

[Means to solve the problem]

In order to achieve the above purpose, the structure of furniture with legs such as tables and desks in the present invention is The support plate 3 that places the corner of the deck 1 on the corner of the frame 2 that surrounds the periphery of the deck 1 The support plate 3 is provided with screw joints 5 of the legs 4, and the bottom of the support plate 3 is It is characterized by having an auxiliary cylinder part 6 that can hold and tighten the leg body 4 on the surface side. be.

[0007]

[Effect]

In addition to screwing the legs 4 to the support plate 3, Since it is also possible to tighten the leg body 4 by using It won't come off no matter what.

[0008] In addition, the leg body 4 is mainly fixed by the tightening force of the auxiliary cylinder part 6, and the leg body 4 and the support plate 3 are The height of deck 1 can be adjusted by using the screw mechanism as a displacement device. can.

【Example】

Hereinafter, embodiments will be described in detail based on the drawings. First, deck 1 is rectangular, as shown in Figure 4. Two screw holes 25 are provided near each corner of the back surface so that the screw holes 25 are provided at two locations. Next The frame body 2 is made of a metal pipe with a substantially D-shaped cross section, and is rectangular so that it can surround the periphery of the deck 1. It is bent into a shape, and the four corners of the inner side wall 7 and both sides slightly away from the corners Elongated rectangular horizontal holes 8 are bored at the required positions, and the above-mentioned holes are bored in the bottom wall 9. Small circular bottom holes 10 are bored at positions corresponding to the horizontal holes 8, respectively. Next, support The retaining plate 3 is made of metal and has a substantially triangular shape, and each corner has the same direction (at the top corner). A tongue-shaped mounting piece 11 is provided protrudingly facing in the normal direction of A screw hole 12 is provided, and a substantially circular shape protruding toward the bottom surface is formed by drawing in the substantially central part. A step portion 13 is provided, and a through hole 14 is bored approximately in the center of the step portion 13. Weld a nut 16 to the top surface of 13 so that the screw hole 15 matches the through hole 14. Then, a screw joint 5 of the leg 4 described later is provided, and the lower surface of the stepped portion 13 is made of metal. An auxiliary cylinder part with an axial groove 17 provided on a part of the side surface is welded, and the groove 17 is Tightening pieces 18 and 19 are provided protrudingly at opposing positions on both edges of the A tightening bolt 20 is passed through the attachment pieces 18 and 19, and a nut 21 is screwed onto the tip thereof. The inner diameter of the auxiliary cylinder part 6 can be elastically expanded or contracted by loosening or tightening. In addition, through holes 22 are bored in two places other than the step part 13 on both sides of the auxiliary cylinder part 6. are doing. Next, the leg body 4 has a mounting screw 23 protruding perpendicularly to the top end surface, and an external mounting screw 23 is provided at the top end. A fitting shaft portion 24 with a slightly smaller diameter is provided.

0010 The support plate 3 is installed by inserting the mounting piece 11 into the horizontal hole 8 of the frame body 2 and then attaching it to the bottom hole 10 of the frame body 2. It is fixed to the frame 2 by screwing the screw 26 inserted into the screw hole 12. Note that the support plate 3 can be formed integrally with the frame body 2 from the beginning, but in this embodiment, By making it an attachable type, the shape of the frame 2 is simplified and manufacturing becomes easier. There is an advantage. In addition, by orienting all the mounting pieces 11 of the support plate 3 in the same direction, Therefore, the attachment piece 11 can be easily inserted into the horizontal hole 8 of the frame body 2. Also support By providing the stepped portion 13 on the plate 3 by drawing, it can withstand the load of the deck 1, etc. The rigidity of the supporting plate 3 is increased. The deck 1 is fitted inside the frame 2, Place the four corners on the top surface of each support plate 3 and insert it through the through hole 22 of the support plate 3. It is fixed by screwing the screw 27 into the screw hole 25. The leg 4 is fitted at the upper end. Insert the mating shaft part 24 into the auxiliary cylinder part 6 on the lower surface side of the support plate 3, and tighten the mounting screw 23 at the top end. is inserted through the through hole 14 of the stepped portion 13 of the support plate 3 and screwed into the screw hole 15 of the nut 16. be done. A tightening bolt 20 passed through the tightening pieces 18 and 19 of the auxiliary cylinder section 6 is threaded at its tip. When the attached nut 21 is tightened, the inner diameter of the auxiliary cylinder part 6 is reduced and the fitting shaft part 2 of the leg body 4 is tightened. 4 is tightened. Therefore, the connection between the mounting screw 23 of the leg 4 and the screw hole 15 of the nut 16 is Even if the screws loosen, the legs 4 will not come off. Also, when the nut 21 is loosened, the auxiliary cylinder part The inner diameter of the leg 6 expands and the tightening of the leg 4 becomes weaker, allowing the leg 4 to rotate and move up and down. Freedom of movement. When the legs 4 are rotated in this state, the legs 4 are raised upwards with respect to the support plate 3. Since it is displaced downward, the height of the deck 1 can be adjusted by rotating the legs 4 appropriately. Ru. Note that when the legs 4 are rotated so as to make the deck 1 higher, the legs 4 are lowered relative to the support plate 3. is relatively lowered and the top end surface 28 of the leg 4 is separated from the support plate 3 as shown in FIG. , only the mounting screw 23 remains in contact with the support plate 3, and the screw of the mounting screw 23 remains in contact with the support plate 3. This will result in an unstable situation where only the mounts support the load, so fix the mounting screw 2 in this way. 3 and the nut 16 as a displacement device, it depends on the tightening force of the auxiliary cylinder part 6. mainly fixes the leg body 4. In other words, the leg body 4 is tightened and fixed by the auxiliary cylinder part 6. Therefore, the mounting screw 23 and nut 16 can be used as a displacement device. It is possible.

[Effect of the idea]

The present invention is as described above, and even if the screw connection between the leg body 4 and the support plate 3 becomes loose, the auxiliary cylinder The tightening by the section 6 has the effect of preventing the accident of the leg body 4 coming off, and also By using the cylindrical portion 6 as the main fixing device for the leg 4, the screw between the leg 4 and the support plate 3 is secured. Since the height mechanism can be used as a displacement device, the height of deck 1 can be adjusted freely. It has the effect of
