Description

  The present invention relates to a structure for attaching a cover (also referred to as a lid) provided in a wiring duct that accommodates wiring such as a power cable and a communication cable of a personal computer or the like provided under a table or desk top plate.

  A technique of providing a cover (or lid) that can be opened and closed or detachably attached to a wiring duct provided under a top plate such as a table is already known.

  Conventional wiring duct covers usually employ either a removable cover or an openable / closable cover with a hinge, and the removable cover and the openable / coverable cover are selectively used as the same wiring duct. There is nothing that can be installed.

  In the case of wiring duct covers, there are users who think that a removable type that can be used with the cover (lid) removed is desirable depending on the user of the table etc. and the usage mode of the table etc., but it is not used from the viewpoint of appearance etc. Some users want to keep the cover (cover) at times. In view of this point, there is also a cover size that can secure a gap that does not interfere with the wiring even if the cover is left in the opening, but this type of wiring duct can be selectively used with an openable cover and a detachable cover. There is nothing that became.

  However, for manufacturers of tables and the like, manufacturing and stocking two types of specifications in the wiring duct cover on a table or desk with the same specifications is reflected in the cost of the table or the like. Therefore, the specifications and structure of the wiring duct cover must be as simple as possible, including whether the equipment type is detachable or openable, in order to suppress cost increases.

In addition, even if the wiring duct cover has a simple structure, the cover may not come off or fall into the duct even if a heavy object such as a PC is placed on the top when it is closed or closed. is necessary.

  In the above-described configuration of the present invention, the cover support member is formed to have a substantially U-shaped cross section that is superposed on and mounted on the base member, and has a hinge shaft protruding on the upper surface thereof. Here, whether or not the hinge shaft is formed integrally with or separately from the cover support member is arbitrary.

The hinge shaft is formed so that the upper surface of the cover body is substantially aligned with the upper surface of the top plate when the cover body is mounted on the shaft so as to be raised and lowered.
The hinge shaft is provided in a back-to-back (left-right symmetric) manner at the center of the upper surface of the cover support member or in the vicinity thereof (that is, substantially at the center of the opening), and when two cover bodies are opened on each hinge shaft Provided in a back-to-back manner.

In the wiring duct cover of the present invention, the cover support member is provided with a cover receiver that is substantially parallel to and substantially at the same height as the hinge shaft for supporting the cover body from below.
Therefore, the cover body can be removed from the hinge shaft, and a flat plate detachable cover (not shown) can be disposed on the hinge shaft and the cover receiver in this state. The detachable cover body is provided with an attachment portion such as a downward recess or an opposing wall that fits at least on the hinge shaft or the cover holder on the lower surface thereof for positioning, slippage prevention, etc. when attaching to the opening. Is desirable.

  The removable cover according to the present invention includes a type in which the cover support member is attached to the base member in a state where the cover support member is detached from the base member. In a detachable cover of the type that is directly mounted on a base member with the cover support member removed, a leg-shaped or skirt-shaped raised portion is formed on the lower surface side of the cover in order to align the upper surface with the top plate surface.

  In any of the above-mentioned cover bodies, a gap is formed between the outer edge side of the cover body and the inner edge side of the opening of the top plate when the cover body is closed or attached. It is formed in the width (width with respect to the width of the opening).

  In the present invention, in the wiring duct cover attached to the wiring duct formed by the opening formed in the top plate and the substantially groove-shaped duct body disposed under the top plate of the opening, the opening or wiring A cover having a mounting portion for a base member for mounting a cover at an appropriate pitch on both sides along the longitudinal direction of the duct, and a base member mounted on the mounting portion having a hinge shaft on the upper surface parallel to the opening. Since the support member is mounted and the cover body provided with a hinge on the hinge shaft of the cover support member is attached to the hinge shaft so as to be freely opened and closed, the wiring duct cover is formed. It is possible to provide a wiring duct cover that can be provided and also can be equipped with a detachable cover. Thereby, two types of wiring duct covers can be used in the basic configuration and specification of one wiring duct. In addition to attaching and detaching the wiring duct cover, no tool is used to attach or detach the base member or support member to / from the wiring duct, which is convenient for handling.

Next, an embodiment of the wiring duct cover of the present invention will be described with reference to the drawings.
FIG. 1 is an example of a wiring duct cover according to the present invention, and is a cross-sectional view with the openable cover closed, FIG. 2 is a side cross-sectional view with the cover of FIG. 1 opened, and FIG. FIG. 4 is a right side view of the base member in FIG. 3, FIG. 5 is a front view of the cover support member, and FIG. 6 is a right side view of the cover support member in FIG. 7 is a front view of one hinge shaft, and FIG. 8 is a right side view of the hinge shaft of FIG.

  1 and 2, reference numeral 1 denotes a top plate such as a desk or table. In the example shown in the figure, an opening 2 having a right and left width is appropriately provided at the center of the top plate 1 in the depth direction (front-rear direction). It is formed over substantially the entire length in the longitudinal direction (perpendicular to the drawing). 2 a is an edge member of the opening 2.

  Reference numeral 3 denotes a groove-like or bowl-shaped duct body made of a steel plate or a plastic plate provided to face the opening 2 on the lower surface of the top plate with respect to the opening 2 provided on the top plate 1. Houses equipment such as wiring, chargers, and connectors for electronic devices such as personal computers. In the illustrated example, the duct body 3 is formed to be sufficiently wider than the opening 2 of the top plate 1, and an opening edge portion having a U-shaped cross section is provided at a portion immediately below the opening 2 of the duct body 3. 3a and 3b are formed.

  The edge portions 3 a and 3 b are formed in the length direction of the opening portion 2 so as to have substantially the same length as the length of the opening portion 2. In addition, slits 3c and 3d for inserting and supporting insertion tongue pieces 5a and 5b formed at both ends of the base member 4 described later are formed on the standing walls of the U-shaped edge portions 3a and 3b at appropriate intervals. Yes. When the tongue pieces 5a and 5b are formed of, for example, two bars, holes for inserting the two bars are formed instead of the slits 3c and 3d. In the present invention, the slits 3c and 3d can be provided on the standing wall surface where the edge member 2a of the opening 2 is provided. In this case, the insertion tongue pieces 5a, 5b are formed in a stepped shape on the tip side so that the height of the base member 4 (depth from the top surface of the top plate) is the same as the height of the embodiment.

  Reference numeral 4 denotes a reverse U-shaped base member having insertion tongue pieces 5a, 5b inserted and held in slits 3c, 3d formed in the edge 3a of the duct body 3 at both outer ends. Here, on the left side of the base member 4 provided with the tongue piece 5a, a notch 4a is formed which enters the inside of the member 4 with the insertion tongue piece 5a interposed between the upper and lower sides.

  In the illustrated base member 4, recesses 4 b and 4 c are formed at two locations on the upper surface side, and recesses 4 d and 4 e are formed on the lower surface side corresponding to the recesses 4 b and 4 c. Of these, the recesses 4b and 4c are inserted with leg portions 7a of the hinge shaft 7 attached to the cover support member 6 which will be described later, and the recesses 4d and 4e have locking protrusions 6e provided on the outer surface of the lower end of the cover support member 6, respectively. 6f is fitted.

  The base member 4 is attached to slits 3c and 3d formed in the edge portions 3a and 3b of the duct body 3 provided at an equal pitch along the length direction of the openings 2 of the top plate 1. First, the insertion tongue 5a is inserted into the slit 3c to the depth of the notch 4a in the base member 4, and then the base tongue 5b is inserted into the opposite slit 3d in this state. The member 4 is slid to the right in FIG.

6 is the base member 4 in which the tongue pieces 5a and 5b at both ends are inserted into the slits 3c and 3d of the duct body 3 as described above, and the cross-section (mount) from above is exactly fitted to the base member 4 The cover support member has a size that can be fitted externally, and a cross-section formed in substantially the same length as the inner dimension of the opening 2 forms an inverted U-shape.
On the upper surface side of the support member 6, standing walls 6a and 6b are erected as cover receivers at two positions on the left and right sides of the outer side of the heel, and will be described later near the base on the inner surface side of the walls 6a and 6b. Mounting holes 6c and 6d for the hinge shaft 7 are provided. Reference numerals 6e and 6f denote locking projections provided at the lower part of the inner surface of the cover support member 6, and are fitted into the recesses 4d and 4e of the base member 4. The cover support member 6 is mounted on the base member 4 (the locking projections 6e and 6f are fitted in the recesses 4d and 4e of the base member 4), and the total length of the cover support member 6 is the inner dimension of the opening 2. As a result, the base member 4 cannot slide with respect to the slits 3c and 3d. That is, the support member 6 functions as a lock member during mounting on the opening 2 of the base member 4.

  7 is a hinge shaft. The hinge shaft 7 includes a substantially short cylindrical shaft 7b provided at a position near one of the upper surfaces of the base 7a, and is fitted into the mounting hole 6c (or 6d) of the support member 6 on the lower surface. A leg 7c is provided. Reference numeral 7d denotes a locking projection provided on the outer surface of the leg portion 7c, and is a retaining member that is locked to the lower edge of the mounting hole 6c (or 6d) of the support member 6. The shaft 7b can also be provided symmetrically in the center of the base 7a. Whether the shaft 7 is provided in a deviated manner or in the central portion is a design matter determined by the balance with other members.

  Further, the horizontally oriented shaft 7b is provided with a slit 71b at a portion deviated from the center thereof and with a groove 72b on the outer peripheral surface. The slit 71b has a role to change the wall and secure the detachability of a semi-cylindrical shaft catch portion 8a (hinge) of the cover body 8 to be described later, and the groove 72b is a contact surface between the catch portion 8a and the shaft 7b. It has a role to reduce friction.

  The two hinge shafts 7 are mounted in the mounting holes 6c and 6d of the cover support member 6 with their directions symmetrical (see FIGS. 1 and 2). Although the illustrated hinge shaft 7 is formed separately from the cover support member 6, it is optional whether the shaft 7 is formed integrally with the cover support member 6. This is because if the cover support member 6 and the hinge shaft 7 are both made of synthetic resin as an example, the integration of the members 6 and 7, separate molding, and manufacture can be arbitrarily selected.

  8 is an open / close type cover body attached to the hinge shaft 7, and a semi-cylindrical shaft catch portion 8a that is rotatably fitted to the shaft 7b of the hinge shaft 7 is hinged on one side of the lower surface. On the other hand, a downward tongue piece 8b is provided on the other side of the lower surface, and is formed of an aluminum extruded material as an example. The cover body 8 may be made of a plastic material or a wood-based material in addition to a metal material such as aluminum.

  For example, when the semi-cylindrical shaft catch portion 8a is fitted to the shaft 7b in the standing state of FIG. 2, the catch portion 8a attaches the shaft 7b to about 180 to 190 degrees. Since it is held in the range, when it is tilted as it is as shown in FIG. 1, the bottom surface of the cover body 8 comes into contact with the top of the standing wall 6a (6b) of the support member 6 and is held in a horizontal posture, that is, in a closed state. . When the catch portion 8a is fitted to the shaft 7, the wall of the slit 71b provided on the shaft 7 is bent to facilitate the fitting of the catch portion 8a.

  In the above-described closed state, a sufficient gap G through which the wiring can be inserted is secured in the direction of the outer end (non-hinge side) of the cover body 8 and the vertical member 2a of the opening 2, so that the complete cover is closed. You can keep the wiring in the state.

  On the other hand, when the cover body 8 is opened as shown in FIG. 2, the opening 2 is greatly exposed, which is convenient for taking in / out the wiring bundle, taking in / out the equipment, or performing maintenance thereof. is there.

  In the duct cover of the present invention formed on the openable cover by the hinge mounting described above, the cover body 8 is removed from the shaft 7b, and in this state, the shaft 7b of the hinge shaft 7 and the upper surface of the standing wall 6a (6b) (the shaft 7 and the upright wall 6a (6b) are formed at substantially the same height), and a flat cover body (not shown, a plate body having the same width as the entire width of the two cover bodies in FIG. 1) is mounted. When mounted, this cover body can be used as a detachable cover body. In this case, the left and right upright walls 6a and 6b and a hanging wall that sandwiches the shaft 7b are provided on the lower surface of the detachable cover body, so that the cover body can be positioned, prevented from being displaced, and prevented from coming off.

1 and 2 with the cover body 8 attached to the support member 6 via the shaft 7b and the catch portion 8a of the hinge shaft 7, or after removing the cover body 8 from the shaft 7b. When the support member 6 is removed from the base member 4 (after the locking projections 6e and 6f are removed from the recesses 4d and 4e of the base member 4), only the base member 4 is provided in the opening 2 at an equal pitch in the length direction. Remain.
Therefore, in the present invention, even if a cover body (not shown) having a bulkiness (or thickness) whose upper surface is the same as the upper surface of the top plate 1 is mounted on the base member 4, The same effect as the detachable cover body can be obtained.

  In the above embodiment, since no tools are used for attaching / detaching the base member 4, the cover support member 6, and the hinge shaft 7, which are constituent members of the present invention, in changing the cover type (opening / closing type) The tool can be changed without using any tools.

  The present invention is as described above. In the wiring duct cover attached to the wiring duct formed by the opening formed in the top plate and the substantially groove-shaped duct body disposed below the top plate of the opening. A mounting portion of a base member for attaching a cover is formed at an appropriate pitch on both sides along the longitudinal direction of the opening or the wiring duct, and a hinge parallel to the opening is formed on the base member mounted on the mounting portion. Since a cover support member having a shaft on the upper surface is mounted, and a cover body having a hinge on the hinge shaft is attached to the cover support member so as to be openable and closable on the hinge shaft, a wiring duct cover is formed. The hinge opening / closing type cover and the detachable type cover can be selectively applied according to preference simply by replacing them.

  As a result, manufacturers can respond quickly to demands for either type of duct cover by preparing two types of cover bodies, openable and detachable, for wiring ducts with common basic specifications. Can do.
