Japanese Patent No. 5792805

However, with such a structure, since the beam is attached to the bracket on the lower reference, variations in the height of the upper end and upward surface of the beam in the support structure are likely to occur due to beam manufacturing errors and assembly errors. .

For this reason, for example, when the top plate support surface is formed on the upper surface of the support and the extension top plate is attached by hooking the bracket on the upward surface of the beam, the extension top plate is higher than the top plate. It becomes easy to shift | deviate to a direction and the malfunction that the expandability of a top-plate surface is inhibited arises.

Furthermore, since this type of beam is also used for mounting an optional member of a desktop panel, the same problem as described above may occur for the optional member.

The present invention has been made in view of such problems, and an object of the present invention is to provide a new furniture with a top plate whose beam mounting structure has been reviewed.

In the present invention, in order to achieve such an object, the following measures are taken.

That is, the furniture with a top plate of the present invention comprises a support structure formed by connecting a plurality of supports with a beam, and when the top structure is supported by the support structure, the furniture is integrated or strong. A bracket having a recessed portion that is connected and opens downward; and a fixture that is attached to and detached from the bracket. The beam is applied below the recessed portion of the bracket, and the beam The bracket is fixed to the bracket and the bracket and the fixture are connected with the beam sandwiched therebetween.

With this configuration, the beam is attached to the bracket on the upper reference, so even if there is a manufacturing error or assembly error of the beam, there is almost no effect on the height of the upward surface (upper end) of the beam in the support structure. It will not come out.

Therefore, for example, when the top support surface is formed on the upper surface of the support and the extension top plate is attached by hooking the auxiliary bracket on the upward surface of the beam, the height of the extension top plate relative to the top plate The positioning accuracy in the vertical direction is improved and the top surface is secured once.

Furthermore, when an optional member such as a desktop panel is attached to the beam, the positioning accuracy in the height direction can be improved as described above.

In order to ensure the accuracy of positioning even if the construction is easy, the beam has a rectangular cross section arranged in a rhombus direction with the corners facing up, and the fixture has a recess that opens upward. Preferably, the concave portion of the bracket and the concave portion of the fixture are in a relationship of fitting to the diagonal position of the beam.

Alternatively, it is preferable that the bracket is formed by integrally forming a top plate support surface for supporting the top plate together with the downward concave portion.

In order to securely fix the beam to the bracket, it is effective that the bracket is made of die-cast, the fixture is made of an elastic sheet metal, and the fixture is fastened to the bracket with a bolt. It is.

In order to properly attach an optional member or the like to the beam, an auxiliary bracket extending in a direction perpendicular to the beam is engaged with an upward surface of a portion other than the end portion of the beam via an engagement portion, and the opening is opened upward. It is desirable to connect the auxiliary bracket and the auxiliary fixture by applying the concave portion of the auxiliary fixture having the concave portion to the beam from below.

In this case, in order to simplify the mounting operation, a gap is formed between the beam and the top plate, and the engaging portion of the auxiliary bracket is provided at a position away from the end of the bracket by a predetermined distance. It is preferable that the region from the joint portion to the end portion can pass through the above-mentioned region, and the region where the engaging portion is provided cannot pass through the gap.

Alternatively, the bracket has a temporary holding portion, and the temporary holding portion holds the beam so as not to drop out of the recess at a position where it does not interfere with the fixture, and the fixture temporarily holds the beam held in the temporary holding portion. It is also effective to be able to attach to the bracket while leaving the part.

The present invention has a new top plate that effectively improves the accuracy of beam mounting in the height direction even if the beam is mounted on the support structure without processing the beam through the configuration described above. Furniture can be provided.

I have to. The inclination of the hypotenuse of the engaging portion 75a3 corresponds to the inclination of the upward surface 3b of the beam 3.

On the other hand, as shown in FIGS. 4 and 9A and the like, the auxiliary fixture 76 is formed by connecting upper ends of a pair of opposing walls 76a provided in the width direction with attachment pieces 76b. On the upper edge side, a concave portion 76c having an inverted C shape that opens upward is formed. The concave portion 76c is also formed with a groove 76d that opens upward in the corner of the inverted letter C.

Then, as shown in FIGS. 9 (a) → (b), the auxiliary bracket 75 is engaged with the upward surface 3b other than the end of the beam 3 from the direction orthogonal to the beam 3 via the engaging portion 75a3. The concave portion 76c of the auxiliary fixture 76 having the concave portion 76c opening upward is applied to the downward surface 3c of the beam 3 from below, and the bolt V2 inserted through the auxiliary fixture 76 is attached to the auxiliary bracket. It is made to fasten by screwing in 75 thick part 75a2.

On the other hand, the auxiliary bracket 75 to which the extended top plate 5 is attached is provided with an engaging portion 75a3 ′ cut out in an upward triangular notch shape as shown in FIG. 2, instead of the engaging portion 75a3 protruding in the downward triangular shape. Auxiliary bracket 75 for attaching the expansion top plate is inserted into a gap Δ formed between the top plate 4 and the beam 3 from a direction orthogonal to the beam 3 at a portion other than the end of the beam 3, The auxiliary bracket 75 is placed on the beam 3 by engaging 75 a 3 ′ with the corner 3 a located at the upper end of the beam 3.

As shown in FIGS. 1 to 3, at the position where the extended top plate 5 is supported, the other end of the auxiliary bracket 75 having one end attached to the beam 3 is supported by the auxiliary leg 51. This auxiliary leg 51 is also composed of a leg rod 51a and an upper frame 51b in substantially the same manner as the end leg 1, and the extended top plate 5 is attached via the top plate support surface 52z of the bracket 52. A reference numeral 53 in FIG. 2 is a spacer interposed between the top 4 and the extended top 5. The thickness of the spacer 53 corresponds to the gap between the upper surface of the auxiliary bracket 75 and the lower surface of the top plate 4 when the engaging portion 75 a 3 ′ falls into the corner portion 3 a of the beam 3.

Also, the auxiliary bracket 75 that supports the desktop panel 6 is screwed on the inner surface of the desktop panel 6 to the hanging piece 75b shown in FIG.

In FIG. 2, reference numeral 81 denotes an upward channel wiring duct, and reference numeral 77 denotes another auxiliary fixture. As shown in FIG. 4, the auxiliary process tool 77 has

horizontal pieces

77b and 77c at the upper and lower ends of the hanging piece 77a. The horizontal piece 77b is fixed to the lower surface of the top plate 4, and the horizontal piece 77c The bottom wall of the wiring duct 81 is suspended and supported. Further, what is indicated by reference numeral 82 is a curtain, and is further suspended from the wiring duct 81.

As described above, the attachment to the support structure A is completed without processing the beam 3, and optional members such as the extension top plate 5 and the desktop panel 6 can be attached using the beam 3.

Thus, the furniture X with a top plate of this embodiment comprises the support structure A by connecting between the plurality of

legs

1 and 2 as the support body with the beam 3, and the top plate is attached to the support structure A. 4, a first bracket 71 having a recess 71c that is strongly connected to the

legs

1 and 2 and opens downward, and a fixture 74 that is attached to and detached from the first bracket 71 are provided. The beam 3 is applied below the recess 71c of the bracket 71, and the fixture 74 is applied from the position opposed to the first bracket 71 with the recess 74c positioned below the beam 3, and the first bracket 71 and the fixture 74 is connected in a state where the beam 3 is sandwiched between the

recesses

71c and 74c.

If comprised in this way, since the beam 3 is attached to the 1st bracket 71 on the upper reference | standard, even if there exists a manufacturing error and assembly | attachment error of the beam 3, the height and upward direction of the upper end 3a of the beam 3 in the support structure A The influence on the height of the surface 3b hardly appears.

Therefore, the top

plate support surfaces

71z and 72z are formed on the upper surfaces of the

legs

1 and 2, and the extension top plate 5 is attached to the top surface 4 even when the auxiliary bracket 75 is hooked on the upward surface 3b of the beam 3. Thus, the positioning accuracy in the height direction of the extended top plate 5 is improved, and the surface of the top plate surface is secured once.

Furthermore, when an optional member such as a desktop panel 6 is attached to the beam 3, the positioning accuracy in the height direction can be improved as described above.

Further, the beam 3 has a rectangular cross section arranged in a rhombus direction with the corner 3 a facing up, and the fixture 74 has a recess 74 c that opens upward, and the recess of the first bracket 71. 71c and the concave portion 74c of the fixture 74 are fitted to the diagonal position of the beam 3, and the beam 3 is taper-fitted to the concave portion 71c of the first bracket 71, so that the beam 3 does not rattle in the front-rear direction. Positioning becomes easy and positioning becomes easy.

Further, the first bracket 71 is formed by integrally forming a top plate support surface 71z for supporting the top plate 4 together with the downward concave portion 71c at the time of molding, and the positional relationship between the downward concave portion 71c and the top plate support surface 71z. Therefore, when attaching an optional member or the like to the beam 3, the mounting accuracy between the optional member and the top plate 3 is improved.

Specifically, the first bracket 71 is made of die-casting, and the fixing tool 74 is made of an elastic sheet metal. The fixing tool 74 is fastened to the first bracket 71 by the bolt V1, so that there is no looseness. Reliable fastening can be performed.

On the other hand, an auxiliary bracket 75 extending in a direction orthogonal to the beam 3 is engaged with an upward surface 3b of a portion other than the end portion of the beam 3 via an engaging portion 75a3, and an auxiliary member having a concave portion 76c opening upward. The auxiliary bracket 75 and the auxiliary fixture 76 are connected by applying the concave portion 76c of the fixture 76 to the beam 3 from below. Thus, since the auxiliary bracket 75 is engaged with the upward surface 3b of the beam 3 with high accuracy, the accuracy of the mounting height of the auxiliary bracket 75 can be improved. Since the auxiliary bracket 75 can be attached at any position along the beam 3, the degree of freedom of attachment of optional parts can also be improved.

In this case, a gap Δ is formed between the beam 3 and the top plate 5, and the engaging portion 75a3 of the auxiliary bracket 75 is provided at a position away from the end of the bracket 75 by a predetermined distance. Since the region from the joint portion 75a3 to the end portion can pass through the gap Δ and the region in which the engaging portion 75a3 is provided cannot pass through the gap Δ, the auxiliary bracket can be attached later without removing the top plate. Can be engaged with each other at a predetermined position.

Further, the first bracket 71 has a temporary holding portion 71d. The temporary holding portion 71d holds the beam 3 in a state where it does not drop out of the recess 71c at a position where it does not interfere with the fixing device 76, and the fixing device 71c has a temporary holding portion 71d. Since the beam 3 held in the position can be attached to the first bracket 71 while leaving the temporary holding portion, the beam 3 can be temporarily placed and the assembly setup can be improved.

As mentioned above, although one Embodiment of this invention was described, the rhombus shape of a beam may be a thing of a cross-sectional parallelogram shape. In order to achieve the basic operational effects of the present invention, the fixture may have a flat shape without a recess. In addition, the specific configuration of each part is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention.
