Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is of a type in which a top plate is supported by a plurality of mutually independent leg supports, and is suitably used in offices and the like. It is related to a desk.

[Prior Art] Conventionally, as this type of desk, one is known in which the corner portions of a frame are each supported by leg supports, and a top plate is mounted on the frame.

[Problems to be Solved by the Invention] By the way, in the case of such a structure, there is no side panel or front panel as a structural member, so if you want to hide the front side or side side of the desk, you need to use a special curtain plate. must be installed between the leg supports.

One possible way to install such a curtain plate is to suspend and support one edge of the curtain plate on a frame via a bracket, and fix the lower end side to a leg support via a bracket.

However, if the bracket is fixed to the leg support with bolts or the like, the bolt holes will be exposed in the leg support when the curtain plate is removed and used. Since the leg support part is easily exposed to the gaze of the user and others,
If left as is, it will spoil the appearance. Therefore, it becomes necessary to hide the screw hole with a cap or the like. Moreover, in order to be able to attach curtain plates with various vertical dimensions, it is necessary to provide screw holes at various height positions of the leg supports, and this must be done in a way that does not spoil the appearance. Things become increasingly difficult.

An object of the present invention is to ensure that the curtain plate is securely attached to the leg support, and to solve these problems.

[Means for Solving the Problems] In order to achieve the above objects, the present invention takes the following measures.

That is, in the desk according to the present invention, the bottom ff of the curtain plate on the leg support:
The fli side is supported via a pair of brackets, and the leg strut has a vertically continuous groove formed at its inner edge, the opening edge of which is narrower than the inside. be. The curtain plate is arranged between the leg supports in a suspended state. One of the brackets has a thickness such that its tip can be inserted into the groove of the leg support and locked horizontally to a position of approximately 45 degrees with respect to the opening direction of the three grooves. It has a set plate shape, and has a white slit opening at the upper or lower edge at a portion of the distal end corresponding to the opening edge. The other bracket has a distal end having the same thickness as the one bracket, and a distance of approximately 90 mm from the proximal end.
It is bent in the thickness direction, and has a slit opening at the lower edge or the upper edge at a portion corresponding to the opening edge at its tip. Then, the tips of both brackets are inserted into the common groove in a perpendicular state, and the slit-forming portions of both brackets are engaged from above and below, and the base ends of both brackets are brought together so as to be common to the inner surface of the curtain plate. It is characterized by being fastened together using a fastening device.

In order to save the effort of manufacturing two types of brackets with different shapes, it is preferable that the other bracket has a shape obtained by bending the tip of one bracket.

When bending the tip of one bracket to obtain the other bracket, if you want to avoid the holes for inserting bolts etc. from shifting due to the bending, It is preferable to drill a long hole extending in the horizontal direction in the center, and to insert a bolt serving as a fastener through both of the long holes.

[Operation] With this kind of configuration, the tips of both brackets are inserted separately into the groove of the leg support, and then both brackets are slid along the groove in the direction toward each other, and the slit forming part When the brackets are engaged, both brackets cannot be pulled out of the grooves. In this way, when the slit forming parts are engaged and the tips of both brackets are perpendicular to each other, the base ends of both brackets overlap, and the overlapped ends are connected to the inner surface of the curtain plate. The curtain plate can be connected to the leg support by co-tightening and fixing the curtain plate to the leg support. When the base end is fixed to the curtain board in this way, both brackets cannot move relative to each other in the vertical direction, so no matter what posture the desk is tilted to, the meshing relationship between the slit-forming parts will not be maintained. It will no longer be canceled.

The narrow portion of the distal end portion 7a is a plate-shaped member having a thickness such that the rotation can be locked when horizontally rotated to a position of approximately 45° with respect to the opening direction N of the tip portion 7a. A slit 71 opening at the edge or lower edge is provided at a portion corresponding to 19a.

To be more specific, since the groove 19 is opened in the direction that bisects the corner angle of the top plate, the brackets l-7, 7□ inserted into the groove 19 are attached to the sides of the top plate 3. The dimensions are set so that it can be horizontally rotated from a position substantially parallel to 3s to a position substantially parallel to tip side 3t of top plate 1. A slit 71 extending from the center in the vertical direction to the upper or lower edge is formed in the distal end 7a of the bracket 71, 72, and a bolt insertion hole 72, which is a long hole extending horizontally, is formed in the center in the vertical direction of the base end 7b. is perforated. Therefore, the bracket 71 having the slit 71 opened at the lower edge and the bracket 7□ having the slit 71 opened at the upper edge become completely the same by turning them upside down. As shown in FIGS. 10 and 11, in the groove 19 of the leg support 1 that fixes the side curtain plate 51 and the front curtain plate 52, a bracket 7 with a slit 71 opened at the lower edge, and a bracket 72 with a slit 71 opened at its upper edge, and rotate one bracket 7 to a position approximately parallel to the side 3S of the top plate 3, and rotate the other bracket 7□. It is rotated to a position substantially parallel to the tip side 3t of the top plate 3, and in that state, the slit forming portions 7c of both brackets 71 and 72 are engaged from above and below. And on the other hand, Burakeso! - Nut 52 with bolt 73 inserted through bolt insertion hole 72 of 71 buried in the lower end of one curtain plate 51
At the same time, the bolt 73 inserted into the bolt insertion hole 72 of the other bracket 7□ is screwed into the nut 52 buried in the lower end of the other curtain plate 52, and these curtain plates 5+
, 52 are fixed at their lower ends.

Since no curtain plate is provided on the use surface U side of the desk, only the side curtain plate 5 is fixed to the leg support 1 on the use surface U side. As shown in FIGS. 1, 12, and 13, this portion is supported through a pair of brackets 1'73.8.

One of the brackets 73 has its tip 7a inserted into the groove 19 of the leg support 1, and the bracket 73 has an approximately 4-degree angle with respect to the opening direction N of the bracket 19.

It is formed by bending approximately 90° in the thickness direction.

Then, the tips 7a and 8a of both brackets 73.8 are inserted into the common groove 19 in a perpendicular state to form a slit forming portion 7c of both brackets 73.8.

8c are engaged from above and below, and the base ends 7b and 8b of both brackets 73.8 are overlapped. After that, attach both brackets 73.8 to the inner surface 5a of the curtain plate 51 with the bolts 7.
3. Tighten and fix together.

With such a configuration, in the part where only the - curtain plate 51 is fixed to the leg support 1, the tip 7a of the bracket 73 is inserted into the groove 19 of the leg support 1, and the bracket 73 is On the other hand, the tip 8a of the other bracket 8
By inserting the brackets 73.8 orthogonally and engaging the slit forming portion 7C of one bracket 73 and the slit forming portion 8C of the other bracket 8 from above and below, both brackets 73.8 are prevented from coming off from the groove 19. I can do it. At that time, the base ends 7b, 8b of both brackets 73.8
As the two elongated holes 72 and 82 overlap, the elongated holes 72 and 82 communicate with each other with a slight positional shift.

In this state, both long holes 72 are

At the part where the two curtain plates 51 are fixed to the leg support 1, the tips 7a of the two brackets 71.7□ are inserted into the groove 1 of the leg support 1.
9 and then both brackets 71.
When the brackets 71 and 7□ are slid toward each other along the groove 19 and the slit forming portions 7c are engaged with each other, both brackets 71.7□ cannot be pulled out from the groove 19. In this state, if each of the brackets 71.7□ is fixed to the inner surface 5a of the curtain plate 51.5°, the two curtain plates 5+ and 52 are fixed respectively.

Therefore, if it is like this, the curtain plate 51.5□
Even if the leg support 1 is removed, there is only a continuous groove 19 of a constant width running from one end to the bottom end, and no bolt holes or the like that look strange remain. Moreover, the groove 19
Since the opening edge 19a is narrower than the inside, even if the opening edge 19a is left as is without attaching a cover etc.
It is easy to design so as not to spoil the appearance as furniture. Further, the brackets 70.7□ and 73.8 can be slid up and down along the groove 19 and set at desired positions, so it is recommended to prepare a large number of screw holes in advance. The curtain plates 51, 5□ having various dimensions in the vertical direction can be appropriately fixed at optimal positions without any problems.

Furthermore, when fixing only - curtain plates 5 to the leg support 1, the slit forming portion 7C58 of both brackets 73.8
By meshing the base ends 7b and 8b, and fixing the overlapped base ends 7b and 8b to the inner surface 5a of the curtain plate 5, the curtain plate 5 is fixed to the leg support 1. When coupled, both brackets 73.8 cannot move relative to each other in the vertical direction. Therefore, no matter what posture the desk is tilted to, the meshing state of the slit forming portions 7C18C will not be released, and the mounting state of the curtain plate 51 to the leg support 1 can be ensured.

Moreover, since the bracket 8 with the tip portion 8a bent can be obtained by bending the tip portion 7a of the bracket 73 (or 70.7□) in the thickness direction, parts can be made common. Manufacturing efficiency can be effectively increased.

In this case, if the bolt insertion holes provided in both brackets 73.8 are formed in the elongated holes 72.83, these elongated holes 73.83 will have the role of adjustment holes. Therefore, the other bracket 8 can be easily formed by simply bending the tip end 7a of one bracket 7 by 90 degrees in the thickness direction, and the productivity thereof can be reliably increased.

Note that since the upper end portion of the curtain plate is supported by the top plate or frame, it is difficult for the line of sight to reach the suspended portion.

Therefore, any suitable means may be used to attach the upper end portion of the curtain plate without departing from the spirit of the present invention.

Further, the bracket placed on the use surface side of the desk is not limited to one that is bent once and then bent at approximately 90 degrees, but may be one that is bent in the thickness direction with the tip end perpendicular to the other.

[Effects of the Invention] Since the present invention has the above-described configuration, it is possible to easily and reliably fix the lower end of the curtain plate, and the legs of the curtain plate can be fixed in any position in which the desk is tilted. The state of attachment to the support can be ensured.

Moreover, even if the curtain board is removed, screw holes, etc. may remain on the leg supports. In addition, curtain plates of various sizes can be fixed to the leg supports without having to prepare a large number of screw holes in advance, making it possible to easily and appropriately change specifications. It is something that can be dealt with.

In addition, if the other bracket of a pair of brackets that fixes the lower end of the curtain plate has a shape obtained by bending the tip of one bracket, it is not possible to share the bracket parts. It is possible to effectively increase productivity.

When sharing bracket parts, if the holes for bolt insertion are formed into elongated holes, the other bracket can be easily obtained by simply bending the tip of one bracket. This makes it possible to increase manufacturing efficiency.
