Description

[Detailed Description of the Invention] The present invention relates to a device that has the function of a wiring device in addition to its original function as a connecting device when connecting desks that are adjacent on the left and right sides.

In offices and the like, desks are often placed side by side for reasons of aesthetics, effective use of space, or the need for customer service. At this time, it is desirable to connect the desks adjacent to each other on the left and right sides using a connecting device so that the desks do not shift back and forth or left and right. In addition, in recent years, so-called OA equipment such as office computers, document processing machines, and facsimile machines have become widespread, but these OA equipment are often used as systems to fully utilize their capabilities.
OA equipment is placed on each desk adjacent to the left and right above,
These may be connected to each other with cords, but in such cases, and when wiring conventional telephone cords, etc., it is desirable to prevent these cords from protruding outside the desk as much as possible. .

Conventionally, a desk connection device and a wiring device for the above-mentioned needs have been provided separately, so providing both devices on a desk increases manufacturing costs and complicates the structure of the desk. In addition, when it is desired to perform only the above-mentioned connection or wiring function, a device having other functions becomes useless.

Therefore, in the present invention, a cylindrical connecting body that can be inserted into the inside and outside of the leg is provided on the side surfaces of the left and right legs of the desks that are adjacent to each other on the left and right, and the tips of the cylindrical connecting bodies are inserted outside the leg. A male engaging portion is formed on the outer periphery of the distal end of one connecting body, a female engaging portion is formed on the inner periphery of the distal end of the other connecting body, and
By forming both the male and female engaging parts so that they can be engaged with and disengaged from each other only in the vertical direction, both the left and right desks are reliably connected so that they cannot be moved in either the left or right or front or rear directions. The connection and separation operation is extremely simple, and the inner diameter of the pair of cylindrical connectors can be used to insert the wiring cord, allowing a simple device to perform both connection and wiring functions. It's about doing.

Next, the present invention will be explained based on an embodiment.
A storage shelf 6 having an L-shaped cross section or the like is capable of storing wiring cords 5 of OA equipment 4, etc., in the area surrounded by the lower surface of the top plate 2 and the left and right legs 3, 3 of the desk 1.
A cord insertion groove 7 is formed in the rear end surface of the top plate 2 and is cut into a rectangular shape or the like so that the cord 5 can be inserted in the vertical direction.

Each leg 3 of each desk 1 has an outer plate 8 and an inner plate 9 located on the inner side separated from the outer plate ₈ by an appropriate distance l1.
The inner and outer panels 9, 8 are provided with oval-shaped through holes 10, 10, which communicate with each other, at the same position.

Reference numerals 11 and 12 denote a pair of cylindrical connectors inserted into the through holes 10 and 10 of the oppositely facing legs 3 and 3 of the left and right adjacent desks 1 and 1, respectively made of synthetic resin and the like. The cylindrical base portions of the connecting bodies 11 and 12 are long enough to be inserted into the holes 10 and 10 of the inner and outer side plates 8 and 9 of each leg body 3, and the inner diameter portion thereof allows the wiring cord 5 of the OA equipment 4 to be inserted therethrough. A large hole 16 is formed.

The tip of one connecting body 11 is connected to the outer plate 8 of the leg 3.
A U-shaped flange 13 is integrally provided on the lower half of the outer circumferential surface of the connecting body 11 at approximately right angles to the cylindrical axis of the connecting body 11, and an upward convex portion is provided on the upper half of the outer circumferential surface. A male engaging portion 14 such as a semicircular arc-shaped protrusion is integrally provided to protrude substantially perpendicularly to the cylindrical axis of the connecting body 11. Further, on the outer circumferential surface of the cylindrical base of the connecting body 11, a plurality of locking protrusions 15 such as protrusions facing the collar 13 and spaced apart by a dimension substantially equal to the plate thickness _t1 of the outer plate 8 of the leg body 3; 1
5', 15'' are provided.

The tip of the other connecting body 12 also protrudes outward from the outer plate 8 of the leg body 3 by an appropriate distance, and the U-shaped flange 1 of the one connecting body 11 is attached to the outer periphery of the tip.
The annular flange 17 is integrally provided on the front surface of the connecting body 11.
The female engaging portion 20 is integrally provided with the male engaging portion 14 in the above-mentioned manner, and the inner peripheral surface of the female engaging portion 20 is provided with a groove 18 extending around the circumference.
and a protrusion 19 are provided to the one connecting body 11
The other connecting body 12 is configured so as to be detachably engaged with the male engaging portion 14 of the other connecting body 12.
On the outer periphery of the annular flange 17, a plurality of engagement projections 2 such as protrusions are provided at a distance substantially equal to the thickness of the outer plate 8 of the leg body 3, facing the rear surface of the annular flange 17.
1, 21' are provided.

With this configuration, in order to make the desks 1, 1 adjacent to each other on the left and right and to connect the legs 3, 3 facing each other to each other, for example, as shown in FIG. , 10 into which the cylindrical base of the connecting body 11 with the male engaging portion 14 is fitted. At this time, the U-shaped flange 13 is placed in the lower position, and the U-shaped flange 13
When the back surface of the leg body 3 contacts the outer plate 8 of the leg body 3, the inner locking protrusions 15, 15',
15'' comes into contact with the back surface of the outer plate 8 and locks the connecting body 11.
will not fall out. The male engaging portion 14 above the U-shaped collar 13 protrudes outward from the surface of the outer plate 8 by a distance l ₂ .

On the other hand, the through hole 10 in the left leg 3 of the right desk 1,
The cylindrical base of the connecting body 12 with the female engaging portion 20 is fitted into the connector 10. At this time, make sure that the female engaging part 20 is in the upper position, and push it in until the back surface of the annular collar 17 comes into contact with the surface of the outer plate 8 of the leg body 3, and the locking protrusions 21, 21' will come into contact with the back side of the annular collar 17 and lock it. and the connected body 12
It also prevents it from falling out. Next, when one side of the right desk 1 is slightly lifted and the female engaging part 20 of the connecting body 12 attached thereto is fitted from above into the male engaging part 14 of the connecting body 11 on the left desk 1, both connecting bodies 11, 1
The cylindrical axes of 2 coincide with each other, and the downwardly open groove 18 of the female engaging part 20 holds the male engaging part 14 from the outside, so that both the left and right machines 1, 1 do not shift back and forth, and the tip of the female engaging part 20 is held in place by the groove 18. The downward protrusion 19 fits between the male engaging portion 14 and the outer plate 8 and connects both the left and right desks 1, 1 so that they do not separate from each other in the left and right directions.
Since the inner diameter portions 1 and 12 communicate with each other, the wiring cord 5 of the OA equipment 4 etc. can be inserted from the inside of both the left and right desks.

In addition, the male engagement portion 14 of one of the connecting bodies 11
When the male engaging portion 14 is arranged so as to face downward of the leg body 3, the groove 18 of the female engaging portion 20 of the other connecting body 12 can be arranged so as to open upward. In this case, one side of the desk having the male engaging portion 14 is lifted slightly upward and inserted into the female engaging portion 20 from above.

In any case, the male and female engaging portions 14 and 20 are configured to be able to engage and disengage from each other only from above and below. In addition, the dimension in which the female engaging portion 20 of the other connecting body 12 protrudes from the outer plate 8 of the legs must be larger than the sum of the dimensions in which the left and right end surfaces of the top plates 2, 2 of the adjacent desks protrude from the outside of both legs. It goes without saying that this must be done.

In this way, in the present invention, through-holes that communicate with each other are formed in the side surfaces of the legs of the desks that are adjacent to each other on the left and right, and the wiring cords of OA equipment, etc. are inserted into the through-holes. These cylindrical connecting bodies are fitted, and a male engaging portion is provided in the upper half or the lower half of the outer circumferential surface of one of the connecting bodies that protrudes from the outer surface of the leg body. On the other hand, on the inner circumferential surface of the other of the two connecting bodies that protrudes from the outer surface of the leg body, an upper half or a lower half of the male engaging part can be attached and detached only from above or below. The outer periphery of both connectors has a desk connection function, and the inner diameter of both connectors themselves functions as a cord wiring passage. Therefore, there is no need to install separate devices in different locations, and the structure of the desk is simple, as well as the installation work. Since only a pair of left and right connectors are required, the number of parts can be reduced and costs can be reduced. The cord can be pulled under the top plate of an adjacent desk without having to pull it out to the lower ends of the legs, right and left ends, etc., and the cord can be shortened and the appearance does not become unsightly. The operation of connecting and separating the left and right desks is simple, as all you have to do is slightly lift one side of one desk relative to the other, and then fit or separate the male and female engaging parts vertically, and the connected state is also robust. have an effect. In addition, it can be used only for cord wiring without connecting the desks, or conversely, it can be used without wiring by simply connecting the desks.
