Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric device mounted on a tabletop of a desk, for example, an electric wire connected to a stand, a telephone, a computer or office equipment. The present invention relates to a cord wiring box in a desk in which a cord can be stored in a lower rear surface of a top plate. 2. Description of the Related Art In order to arrange a plurality of office desks efficiently in a room, the rear ends of the desks are opposed to each other so as to be in contact with each other, or are arranged in a row in a horizontal direction. Electric devices such as a stand and a telephone are arranged on the tabletops of the desks arranged in this manner, and it is necessary to perform a dedicated wiring work on these electric devices. To make this possible, in a desk where the top plate extends rearward of the left and right legs, a wiring lead hole is provided at an appropriate position on the trailing edge of the extending portion, and the side view shape is substantially forward L. The lower horizontal plate has vertical and horizontal partitions at its front end and center, and cuts through the upper edge of the rear vertical plate. And a wiring case having a length corresponding to the inner dimension between the left and right legs, which is closed at both ends by a vertical blocking member having a wiring hole. An electric wire storage device for a desk, which is fixed to the lower surface, and furthermore, a curtain plate is disposed between the rear portions of the left and right legs with its upper end being in contact with the lower end of the wiring case (see Japanese Utility Model Publication No. Sho 63-35645). ) Has existed conventionally. [0003] However, the electric wire storage device for a desk in the prior art described above has a drawback that it cannot be freely attached and detached freely with one touch because it is screwed with screws. Was. In view of this point, the present invention grasps and contracts an opened portion of a duct having a substantially U-shaped vertical section made of an elastic body and engages it with a concave portion on the back surface of the extended portion of the top plate. At the top of this duct is formed an engaging groove that allows the folder to slide freely, a folder is attached to this engaging groove, and this folder is engaged with the locking hole formed in the recess An object of the present invention is to provide a cord wiring box in a desk in which a box can be assembled with one touch. [0005] In order to solve the above-mentioned problems, the present invention provides a desk, in which a top plate extends rearward from left and right legs, an extended portion of the top plate. A concave portion is formed on the back surface of the top plate, and a wiring cord insertion hole is formed at an appropriate portion of the extended portion of the top plate toward the concave portion. Further, the concave portion has a substantially U-shaped vertical cross section made of an elastic body. A plurality of locking holes for supporting and locking the duct are drilled at appropriate places, and a folder attached to the sliding engagement groove formed at the top of the duct is inserted into the recess formed in the top plate. A technical means was adopted in which a duct was attached to the extended portion of the top plate while being locked to the stop hole. According to the present invention, as a result of adopting the above technical means, the open portion of the duct having a substantially U-shaped vertical section is inserted into the concave portion on the back surface of the extended portion of the top plate, The folder is assembled by engaging with a locking hole formed in a concave portion on the back surface of the extended portion of the top plate. In this way, the duct can be attached to the back surface of the extended portion of the top plate with one touch by utilizing the elasticity of the duct. An embodiment of the present invention will be described below in detail with reference to the accompanying drawings. First, the cord wiring box of the desk of the present invention will be schematically described with reference to FIG. 1. In a desk where the top plate 1 extends rearward beyond the left and right legs 2 (overhang), the extension portion 3 A duct 4 which is a cord wiring box is attached to the trailing edge. In addition, 5 is a curtain. Next, a cord wiring box in the desk of the present invention will be described in detail with reference to FIGS. As can be understood from FIGS. 2 and 3, in a desk in which the top plate 1 extends backward from the left and right legs 2, a concave portion 7 is formed on the back surface 6 of the extension portion 3 of the top plate 1. A wiring cord insertion hole 8 is formed at an appropriate portion of the extension portion 3 of the top plate 1 toward the recess 7.
The recess 7 is provided with a plurality of locking holes 10 for supporting and locking the duct 4 at appropriate locations in a substantially U-shaped vertical section made of an elastic body. Recess 7 formed
A sliding engagement groove 1 formed in the upper part of the duct 4;
The folder 4 attached to the top 1 is locked in the locking hole 10 and the duct 4 is attached to the extended portion 3 of the top plate 1. Further, a curtain plate 5 is provided at the rear of the desk. In this curtain plate, a wiring code take-out hole 13 is formed so that a vertical section made of the elastic body corresponds to a wiring code drawing hole 9 formed in the U-shaped duct 4. Note that duct covers 15 are attached to both sides of the duct 4. Further, the folder 12 is to be locked at at least two or more places at any appropriate place. With the above-described structure, the vertical section made of an elastic body formed by engaging the folder 12 with the engaging groove 11 presses the open portion 16 of the U-shaped duct 4 to shrink it. If the pressing is released by inserting into the concave portion 7 of the extension portion 3 of the top plate 1, the folder 12 engaged with the engaging groove 11 of the duct 4 is inserted into the locking hole 10 formed in the concave portion 7 of the top plate 1. Are engaged and fixed with one touch. When the duct 4 is assembled as described above,
The wiring cords 14 of the electric devices arranged on the top board 1 are inserted into the duct 4 through the wiring cord insertion holes 8 formed in the top board 1, and the wiring cord drawing holes 9 formed in the duct 4. Is inserted into the wiring cord take-out hole 13 of the curtain plate 5 formed so as to correspond to the above, pulled out inside the desk, and connected from each power supply to a wired outlet. In this state, the duct covers 15 are assembled on both sides to complete the operation. According to the present invention, as a result of employing the above configuration,
The following effects are obtained. (1) The duct, which is a cord wiring box, can be freely attached and detached freely with one touch.
