Description

  The present invention relates to a support device for a top plate, and more particularly to a support device for supporting a top plate such as a table or desk with a leg and a frame.

  Conventionally, various tables and desks having a structure in which a top plate is supported by legs are provided, and those having a structure in which the top plates are continuously provided sideways to make the width wide are also known.

  In Patent Document 1, a T-shaped bracket is attached to the upper end of the end leg, the T-shaped brackets of the end legs on both sides are connected by a beam, and the top plate is mounted on the upper portion thereof. And a structure in which the beam is screwed to the lower surface of the top plate. And in order to connect a plurality of top plates to the side, an intermediate leg is used instead of the end leg, and a cruciform bracket is attached to the upper end thereof, and the T-shaped end leg and the intermediate leg of the end leg The cruciform brackets or the cruciform brackets of the intermediate leg are connected by a beam, and the joint portion of the two top plates is placed on the center line of the intermediate leg and placed in the same manner as described above. A screwing structure is disclosed.

  Further, in Patent Document 2, between the end leg and the intermediate leg, between the intermediate legs are connected by the inter-leg module, and the joint portion of both top plates is placed on the center line of the intermediate leg. The structure which screws a top plate in the attachment piece provided in the side of the upper end of the end leg and the middle leg is described.

  In the desk or table described in these Patent Documents 1 and 2, it is not assumed that the end legs are provided at the end of the top plate and the user is seated at the end.

  Patent Document 3 describes a table having a structure in which a pedestal is connected to an end portion of a top reinforcing frame fixed to the lower surface of the top plate, and lower ends of the front and rear pedestals are connected at both sides by a transverse rod. It is done. In this case, it is possible to sit on the end side (short side) of the top plate if the lateral ridge is not a problem, and the position of the pedestal is set closer to the center of the top plate. Although it is possible to prevent the legs from hitting, it is not assumed that the top plates are arranged side by side. Also, if the pedestal is set inward from the edge of the top plate so as not to be in the way, the top plate reinforcement frame connected to the upper end of the pedestal will also be positioned inward, so It is not possible to support the periphery sufficiently.

In addition, both side portions of the connecting plate 14 also form the connecting holes 18, 18. Further, side plates 19 are raised and formed on both side ends of the base plate 11 of the connection bracket 4, and a mounting plate 20 abutting on the lower surface of the top plate 1 is bent outward on the upper edge of the side plate 19. The through holes 21 and 21 are formed on both sides of the mounting plate 20. The fixed plate 12 and the connecting plate 14 and the side plates 19 and 19 constitute a box-shaped structure opened upward, and the strength is further improved by welding each joint. Here, the width (width in the left-right direction) of the support plate 13 is set to 1/2 or less of the width of the upper surface of the upper ridge 9 of the leg 2.

  In the present embodiment, the connection bracket 4 is a single wide component, but may be configured using two or more small connection brackets. Moreover, although the said connection bracket 4 of this embodiment has the board | substrate 11, as long as strength can be given, the shape which abbreviate | omitted the board | substrate 11 may be sufficient. It is sufficient to provide the fixing plate 12 and the connecting plate 14 having at least a predetermined distance.

  The support bracket 5 is a molded product made of synthetic resin or aluminum die-cast, and a vertical portion of the lower surface of the receiving plate 22 having a substantially square shape in plan view in contact with the lower surface of the top plate 1 23, the vertical portion 23 is in contact with the side surface of the upper rod 9 of the leg 2, and a part of the receiving plate 22 outside the vertical portion 23 is used as the mounting portion 24. It is shaped to be able to abut on the upper surface of the upper weir 9. Further, mounting holes 25 are provided at both sides of the vertical portion 23 and the mounting portion 24, and through holes 26 are provided at three places of the other receiving plate 22. The lateral width (the width in the left-right direction) of the placing portion 24 is set to 1/2 or less of the width of the upper surface of the upper ridge 9 of the leg 2 in the same manner as the support plate 13.

  Then, the base end of the connection bracket 4 is detachably connected to the outer side of the upper rod 9 of the leg 2 and the support brackets 5 and 5 are detachably connected to both front and rear end portions inside the upper rod 9. Do. Specifically, while the fixing plate 12 of the connection bracket 4 is in contact with the outer surface of the upper collar 9 and the support plate 13 of the connection bracket 4 is in contact with the upper surface of the upper collar 9, the daruma hole is formed. The fixing plate 12 is attached to the outer surface of the upper collar 9 with screws 27 using 16 and 16, and the support plate 13 is attached to the upper surface of the upper collar 9 with screws 28 using the mounting holes 17 and 17. In addition, with the vertical portion 23 of the support bracket 5 in contact with the inner side surface of the upper collar 9 and the mounting portion 24 of the support bracket 5 in contact with the upper surface of the upper collar 9, the mounting hole 25, Screw on the upper rod 9 using ....

  In the present invention, the structure of the leg 2 is not particularly limited, but it is necessary to have the upper weir 9 at least at the top. The leg body 2 of this embodiment has a corner leg member 2B connected to the upper end of a wooden leg 2A, and a square pipe-like leg crosspiece 2C connected between both corner leg members 2B and 2B to form a gated leg The upper rod 9 refers to a portion including the leg crosspiece 2C and the corner leg members 2B and 2B. The support bracket 5 may be attached across the leg crosspiece 2C and the corner leg member 2B, or may be attached only to the leg crosspiece 2C or only to the corner leg member 2B. Further, the leg 2 may be made of aluminum die cast, and the support leg 2A and the corner leg member 2B may be integrated. Further, the leg 2 may be a leg-like leg.

  Then, the front end of the connection bracket 4 is connected to the inner side surface of the short side frame 7 in a state where the connection plate 14 of the connection bracket 4 is in contact with the inner side surface of the short side frame 7 The connection plate 14 is attached to the short side frame 7 with a screw 29 using the connection holes 18 and 18. Finally, with the mounting plate 20 of the connection bracket 4 and the receiving plate 22 of the support bracket 5 in contact with the lower surface of the top plate 1, the top plate 1 using the through holes 21 and 21 of the mounting plate 20. And screw to the top plate 1 using the mounting holes 25 of the receiving plate 22. A recess is formed in advance on the lower surface of the top plate 1 for releasing the head of a screw for attaching the connection bracket 4 and the support bracket 5 to the upper surface of the upper rod 9.
