Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a desk suitable for mounting and using so-called OA equipment.

[Prior art] When using office automation equipment placed on the top of a desk,
Power lines, communication lines, etc. that are raised from the floor or drawn out from adjacent desks must be routed to the equipment, which poses a problem in how to handle the wiring.

Conventionally, in this type of desk, a duct space is formed between the front panel and an inner panel placed inside it, and a slit for wiring to pass between the tip of the top plate and the upper edge of the front panel. The wiring led out from the floor etc. is guided into the duct space, and from within the duct space is guided onto the top plate through a slit for wiring passage.

In the conventional method, a cantilevered elastic body made of rubber or other soft material is disposed in the slit, and the slit is closed by the cantilevered elastic body so that the duct space is exposed to the outside. Generally, it is prevented. That is, the wiring within the duct space is drawn out to the outside by elastically deforming the cantilevered elastic body.

[Problems to be Solved by the Invention] However, such a cantilevered elastic body made of a soft material tends to have a waving phenomenon on its surface, and there is a possibility that the surface of the cantilevered elastic body made of such a soft material is prone to undulation, and there are This can easily lead to a sense of discomfort in appearance. Further, such a cantilevered elastic body is easily deformed as a whole due to aging, and if used for a long period of time, the discomfort will be exacerbated. Furthermore, such a cantilevered elastic body lacks the ability to support the load placed on it, so if small items are placed on it, the cantilevered elastic body will deform and fall into the duct space. There is a possibility. Therefore, there is also the problem that it is difficult to use the top of the slit as part of the top plate even in the portion where the wiring is not led out.

The present invention aims to solve such 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, a slit for passing wires is formed between the top plate and the edge of the front panel, and the lid body is provided in the slit so as to be openable and closable. The lid body includes a main body made of a hard material and a mounting part provided on the lower edge of the main body via a hinge part, and the mounting part is removably attached to the opening edge of the slit. It is characterized by what it did.

In order to efficiently manufacture the lid, it is preferable that the lid is formed by integrally extruding the main body and attachment portion made of hard synthetic resin, and the hinge portion made of soft synthetic resin.

In order to facilitate the opening operation of the lid, it is preferable that a notch is provided at the end of the lid into which a finger can be inserted, and the door is provided in this notch so that the door can be opened and closed.

Further, in order to diversify the manner in which the wiring is pulled out, it is preferable to configure the attachment portion so that it can be selectively attached to either one opening edge or the other opening edge of the slit.

Furthermore, in order to be able to open and close the minimum necessary portion of the slit to conduct wiring in and out, the lid body can be attached to a common mounting part by attaching multiple bodies that can be opened and closed independently to each other via a hinge part. It is preferable to have them installed in series.

[Operation] With such a configuration, when an upward operating force is applied to the lid, the lid rotates around the hinge portion, and the side of the lid opposite to the hinge is lifted. Therefore, the slit is in an open state, and the wiring below the top plate can be led out onto the top plate by passing through the slit. In cases where there are many wires or when guiding computer paper etc. onto the top plate using the slit,
The entire lid can also be removed.

Note that when the lid is held in the open position,
The slit will be covered by the main body. Since this main body is made of hard material, it is easy to finish its surface to a flat surface without undulations. Therefore, the top surface of the top plate and the top surface of the lid can be made into continuous or parallel surfaces that do not give any discomfort to each other. A main body made of a hard material has higher rigidity than a main body that elastically deforms itself to allow the wiring to pass through. Therefore, it is also possible to use the top surface of the lid body held in the open position as part of the top plate surface.

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 8.

Further, an upper frame 37 is formed on the upper edge 3j of the front panel 3, and a decorative member 38 made of synthetic resin is attached to the upper frame 37. The slit 4 is formed between the decorative member 38 and the top plate 1, and the slit 4 is formed between the decorative member 38 and the top plate 1.
A lid body 41 is attached to the.

The lid body 41 includes a plate-shaped main body 41a made of a hard material, for example, a hard synthetic resin, and a hard synthetic resin provided on the lower edge of the main body 41a via a hinge part 41b made of a soft synthetic resin. The main body 41a s hinge portion 41b and the attachment portion 41c are integrally formed by extrusion molding.

The lid body 41 is held in a hinged manner by elastically pushing its mounting portion 41c into a two-way groove 38a formed in the decorative member 38. Note that a tip member 15 having an undercut portion 15a is provided on the tip end surface of the top plate 1 facing the decorative member 38, and elastic claws 41d and 41e are integrally provided on the lower surface of the main body 41a of the lid body 41. It is protruding from the When the lid body 41 is closed, the elastic claw 41d on the use end side is inserted into the undercut portion 1 of the top plate 1.
5a, and the elastic claw 41e on the tip side elastically engages with the lower surface 38b of the decorative frame material 38, so that the lid body 4
1 in the closed position. by the way,
At both ends of the lid body 41, synthetic resin caps 41 f,
41g, 41h, and 41i are installed.

The cap 41f at the left end of the left lid 41 and the cap 41h at the right end of the right lid 41 are provided with a notch 43 into which a finger can be inserted, and a door 44 is provided in the notch 43 so as to be openable and closable. There is. Specifically, cap 41f141
As shown in FIG. 7, h is equipped with an end plate 101 that is fan-shaped in side view, and a protrusion 102 protruding from the inner surface of the end plate 101. It is fixed by press-fitting and adhering between holding protrusions 41j which are protruding from each other and have an L-shaped cross section. And end plate 10

A guide groove 103 is provided on the inside surface of the notch 43, and both guide grooves 103 are provided with both side edges 44 of the door 44.
a is slidably engaged. The door 44 has a flat plate shape with a handle portion 44b at its outer end, and an engaging pawl 44c having an undercut portion on its lower surface protrudes from its inner end. This engaging claw 44c is connected to the caps 41f and 4.
The door 44 can be locked in the open position by engaging with the inner edge of the horizontal wall 104 provided along the lower edge of the inner end of the guide groove 103 of 1h. , 4
1h, the engaging claw 44c is elastically deformed upward so that it can pass over the horizontal wall 104. The solid line in FIG. 8 shows a state in which the door 44 is locked in the closed position, and the imaginary line in the figure shows a state in which the door 44 is pushed inward and the notch 43 is opened. When the notch 43 is opened, a finger can be inserted into the notch 43, and the lid 41 can be urged upward by hanging the finger on the horizontal wall 104. It's Nishide. In addition, if it is desired to always apply stable and appropriate braking to the movement of the door 44, for example, as shown in FIG. 44d may be provided, and this raised portion 44d may be brought into elastic contact with the inner surface of the guide groove 103.Also, as shown in FIG. An auxiliary lid 42 having a similar cross-sectional shape is provided. This lid 42 plays the role of a spacer, and can be opened and closed independently of the lid 41 and can be attached and detached.

According to such a configuration, when an upward operating force is applied to the lid 41, the lid 41 rotates around the hinge portion 41b, and the side of the lid 41 opposite to the hinge is lifted.

Therefore, the slit 4 becomes open, allowing the wiring A located below the top plate 1 to pass through the slit 4 and lead out onto the top plate 1. FIG. 1 shows an example of wiring with the slit 4 opened in this manner. In this case, first, the wiring A raised from the floor F is guided and held on the gutter 36 through the wiring passage port 28 and the groove 26, for example. And this gutter 36
The wiring A drawn out to one side from -F is guided to the top plate 1- through a slit 4 for passing the wiring.

By the way, when the lid body 41 is held in the closed position, the slit 4 is covered by the main body 41a. Since the main body 41a is made of a hard material, it is easy to finish its surface into a flat surface without undulations. Therefore, it is possible to make the upper surface of the top plate 1 and the upper surface of the lid body 41 parallel planes that do not give a sense of discomfort. The main body 41a made of a hard material has higher rigidity than a main body 41a that allows the wiring to pass through by elastically deforming itself.

Therefore, it is also possible to utilize the upper surface of the lid body 41 held in the open position as part of the top plate surface.

In addition, in the embodiment described above, a case was explained in which the lid body could be supported only on one opening edge of the slit, but as shown in FIGS. 10 and 11, the mounting portion 241c is , one opening edge 20 of the slit 204
4a or the other opening edge 204b. That is, the first
0 and 11, not only the upward groove 38a is formed in the decorative member 38 of the front panel 3, but also the upward groove 15b is formed in the tip member 15 of the top plate 1. Then, the mounting portion 241c of the lid body 241 is attached to the upward groove 38a.
, 15b can be selectively attached. However, if you do this, the slit 20
4 can be opened in a desired front-back direction. In addition, in the figure, 241a is the main body of the lid body 241, and 241b
is the hinge part.

Furthermore, the structure of the lid body itself is not limited to the one described above, and may be, for example, as shown in FIGS. 12 and 13. That is, the lid body 341 includes a plurality of main bodies 341a that can be opened and closed independently and connected to a common attachment part 341c via a hinge part 341b. Then, as shown in FIG. 13, this mounting portion 341c is
It is adapted to be removably fitted into an upward groove 338a provided at the opening edge of the slit 304. In this way, the minimum necessary portion of the slit 304 can be opened and closed to lead out and take out the wiring, and the other closed lid body 34 can be opened and closed.
1 can be used as a part of the top plate 1. Since the lid body 341 having such a configuration can be handled as one integral unit, it is easier to handle than when a large number of short lid bodies are used, and parts can be easily handled. Loss etc. can also be effectively prevented.

[Effects of the Invention] Since the present invention has the above-described configuration, it is possible to effectively prevent a waving phenomenon from occurring on the surface of the lid that closes the slit. Therefore, there is no appearance of discomfort between the top surface of the top plate and the top surface of the lid, and the visual elegance can be enhanced. In addition, such a lid body is
It is easy to prevent defects such as deformation due to aging, and the desired appearance can be maintained for a long period of time.

Furthermore, such a lid body can have a higher supporting force against overloading load than a conventional cantilevered elastic piece.
Even if small items are placed thereon, problems such as falling into the slit can be prevented. Therefore, in the portion where the wiring is not led out, the slit can be used as part of the top plate without any problems.

Therefore, the basic functions of a desk can be improved by one point compared to conventional desks.

Then, the lid body is made of a hard synthetic resin body and a mounting part,
If the lid body is integrally extruded with the hinge portion made of soft synthetic resin, the lid body can be manufactured particularly efficiently.

Additionally, if a notch is provided at the end of the lid into which you can insert your finger, it will be easier to hook your fingers onto the closed lid, making it easier to open the lid. can. If the door is provided in this notch so that it can be opened and closed, the appearance when not in use can be improved. In addition, by doing so, it becomes possible to draw out a low-volume wiring onto the top plate using this notch, which does not require opening the lid.

Furthermore, if the attachment part is configured so that it can be selectively attached to either one opening edge or the other opening edge of the slit, the opening direction of the slit can be set to either the front or back, It is possible to diversify the manner in which wiring is drawn out.

Furthermore, if the lid body is made up of a common mounting part with multiple bodies that can be opened and closed independently connected to each other via a hinge part, wiring can be led out by opening and closing only the minimum necessary part of the slit. This makes it possible to improve the appearance during use, and also allows the top of the lid to be used more effectively as part of the top plate surface.
