[Industrial applications]

 The present invention relates to a wiring duct device provided below a top plate of a desk, and more particularly to a wiring duct device provided with an outlet mounting portion in a wiring duct.

[0002]

[Prior art]

 Conventionally, a desk equipped with an outlet for connecting a cord plug of an office automation equipment or the like has a device described in, for example, Japanese Patent Laid-Open No. 2-177907. This desk is designed so that an outlet is placed on a gutter provided above the desk.

However, since the connection port of the above-mentioned outlet is facing upward, dust, water, etc. easily enter through the connection port, which may lead to an unexpected accident. Also, since the outlet is simply placed on the gutter and the cord is still hung, when moving OA equipment, etc., the outlet falls from the gutter or the cord is pulled, Unnecessary force may be applied to the cord and it may break. Moreover, when trying to insert and remove the cord plug when moving OA equipment, etc., when the gutter is located at the back, the cord cannot be easily inserted and removed, which is troublesome. Had.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. 1 and 2, the top and bottom surfaces of the top plate (2) fixedly mounted on the upper surfaces of the left and right sleeves (1) and (1) have a cross section that is generally upwards in a U-shape or a rectangular tube shape in the left-right direction. A plurality of reinforcing rods (3) and (4) facing the front are provided at appropriate intervals in the front-rear direction.

The second reinforcement rod (4) from the rear is provided on the front face (4a) and the rear face (4b) with an engaging portion (5) having a downward wedge shape and an upper end face horizontal. ing.

On both sides of the inner surface of the sleeves (1), both sides of the back plate (6) are fixed with a plurality of stoppers (7).

A fold-back portion (6a) is formed at the upper end of the rear plate (6) and is folded back in an inverted J shape toward the front. The fold-back portion (6a) has a front lower end facing rearward. Bent pieces (6b) are arranged in a row.

1 and 2, (A) shows a wiring duct device made of synthetic resin. (8) is a duct main body having a substantially U-shaped cross-section that opens to the front (the right side in FIGS. 1 to 3) and is oriented in the left-right direction. On the upper surface of the upper piece (8a) in the upper part, a pair of front and rear engaging members (10) having inward engaging claws (9) at the upper end are erected over the entire length of the duct body (8). .

[0012] Reference numeral (11) is a left-right direction socket mounting portion provided on the front surface of the vertical surface (8b) of the duct body (8). The horizontal piece (11a) is formed by providing inwardly projecting pieces (11b) vertically opposed to each other.

[0012] (12) is fitted in a space (s) formed by the inward projection piece (11b), the horizontal piece (11a), and the vertical surface (8b), and has a thread groove ( 13) is a cut rectangular metal plate nut.

An outlet (15) whose connection port (14) faces forward is housed in the duct body (8) and is inserted into two circular holes (15a) formed in the outlet (15). By screwing these two bolts (16) into the screw groove (13), the outlet (15) is attached to the outlet attachment portion (11) in the state of being attached to the attachment portion (11). There is.

The length of the outlet mounting portion (11) in the left-right direction is not always the same as the distance between the sleeves (1) (1). It need not be, and may be a part of it. Reference numeral (17) is a cord plug of an OA device (not shown) connected to the connection port (14).

A rear extending piece (18) extending rearward at a substantially right angle is continuously provided at a lower end of a vertical surface (8b) of the duct body which faces the vertical direction.

On the upper surface of the middle portion of the rear extending piece (18), an elastic hooking piece (20) whose upper part is bent forward in an inverted V shape is erected, and this hooking piece (20) By engaging the lower end of the front piece (20a) with the rear edge of the bent piece (6b) of the rear plate (6), it is possible to prevent the rearward extending piece (18) from moving forward and downward. It is like this.

The duct main body (8), the engaging claw (9), the engaging member (10), the rear extending piece (18), the elastic tongue piece (19), and the hooking piece (20) have horizontal lengths. , The distance between both sleeves (1) (1) is almost the same.

In order to mount the above-mentioned wiring duct device (A) on the temporary surface of the top plate (2), it is provided on the front and rear surfaces (4a), (4b) of the reinforcing rod (4) on the temporary surface of the top plate (2). The inward engaging claw (9) of the engaging member (10) is pushed up from the lower side to the engaging protrusion (5) and locked, and the elastic tongue (19) is held between the sleeves (1) and (1). The lower end of the front piece (20a) of the hooking piece (20) may be locked to the front edge of the bent piece (6a) of the rear surface plate (6) while being brought into contact with the rear surface plate (6). In this way, the duct body (8) can be easily attached to the temporary surface of the top plate (2) without accidentally coming off.

Further, since the outlet mounting portion (11) is provided in the duct body (8), the substantially vertical surface (8b) of the duct body (8), both horizontal pieces (11a) and both inward projections. Inside the space (S) formed by the piece (11b), the plate set (12) screwed to the tip of the bolt (16) that penetrates the outlet (15) is inserted into both inner protrusions (11b). ) And tighten the bolt (16), the plate nut (12) is rotated with the bolt (16) and rotates slightly, and the corners located on the diagonal line contact both horizontal pieces. . If the bolt (16) is further tightened in that state, the outlet (15) is tightened to the socket attachment part (11) while engaging with the inside of the inward projection (11b) of the plate nut (12). To be done.

Since the front surface of the duct main body (8) is opened when the wiring duct device (A) is attached to the lower surface of the top plate (2), the outlet (15) as described above is connected to the duct main body ( 8) After it is attached to the outlet mounting part (11) inside, the plug (17) can be connected to the connection port (14) of the outlet (15) from the front of the duct body (8). It is easy to carry out, and the cords can be stored in the duct body (8) at the same time, which is convenient. Also, the cord can be easily pulled out in the same manner.

Furthermore, since the wiring duct device (A) is supported by the reinforcing rod (4) and the rear surface plate (6), the wiring duct device (A) bends when the cord plug (17) is inserted or removed. There is no risk of bending or bending.

In addition, since the outlet (15) is installed in the duct body (8) with the connection port (14) of the outlet (15) facing forward, dust, water, etc. enter from the connection port (14). Fear is reduced.

[0024]

[Effect of device]

 The present invention has the following effects. (a) Insert a screw plug for outlet installation into the outlet mounting part on the front of the vertical surface of the wiring duct body that faces the left and right, and screw the bolt inserted through the outlet into the screw groove provided on the screw seat. By combining them, the outlet is attached to the outlet attachment part, so that the installation is easy, and by loosening the bolt, the outlet can be easily moved.

(B) Since the inside of the wiring duct and the outlet are mounted so as to face forward, the risk of dust, water, etc. entering the connection port of the receptacle is reduced. It is also easy to insert and remove the plug from the outlet.

(C) Since the outlet is attached to the main body of the wiring duct with the plate nut and the bolt, even if the outlet is moved to an OA device on the desk, the outlet may fall out of the wiring duct, or an unreasonable force may be applied to the cord. It does not hang.

Further, since the outlet can be easily moved by loosening the bolt, the optimum mounting position can be selected depending on the position of the office automation equipment on the desk or the outlet on the floor.
