Description

[Detailed description of the invention] Industrial application field This invention is a wiring frame for storing wiring connected to various devices, such as partitions and OA.
This invention relates to a wiring frame that is removably attached to a recess in a frame provided in a desk or other equipment.

Prior Art This type of wiring frame was proposed by the applicant in Utility Model Application No. 61-28429 (1987-156533), and later published in Utility Model Application No. 2-47848. Desk frame structure with wiring conduit
(first-filed invention).

In addition, other related wiring frames include, for example, Utility Model Publication No. 37-10952 (conventional example 1) and Utility Model Application Publication No. 48-
Some of these are disclosed in Japanese Utility Model Publication No. 89397 (Conventional Example 2) and Japanese Utility Model Publication No. 52-31439 (Conventional Example 3).

The above-mentioned prior invention consists of a structure of a frame for a desk, which is provided with a drawable conduit structure forming a conduit in a drawable state and has at least one beam, and in which the conduit conduit structure is arranged in a cross section. Two protrusions are provided at a distance from each other, and with the wiring conduit structure inserted, each of the protrusions is supported by a wall attached to the beam, and connected between the protrusions on the side closer to the beam. a member is provided, and at least one spring member is provided, the spring member being in tension in the plugged condition of the wiring conduit structure and holding the protrusion with its end away from the beam when withdrawn. This is a structure that is spread out to the farthest distance from each other.

Conventional Example 1 described above includes a housing in which arc-shaped covering pieces are formed from both sides of the bottom plate to the top side so that their leading edges face each other, and a cross-sectional shape that is attached between each covering piece of this housing. A wiring frame is constituted by the arc-shaped cover plate, and horizontal grooves are formed on both edges of the cover plate along the longitudinal direction in which the wiring frame extends, and the leading edge of each cover piece fits into the horizontal groove. The lid plate is attached to the housing in such a manner that the lid plate is attached to the housing.

In the above-mentioned conventional example 2, recesses are provided on both sides or the bottom of the wiring gutter, and these recesses are fitted into a plurality of protrusions formed on a connection fitting attached to the wiring gutter mounting surface in advance. The structure is such that the wiring troughs are installed in parallel.

In the conventional example 3 described above, a partition plate support on the inner surface of the vertical plate of a line gutter with a groove-shaped cross section is provided, a removable cover with an inverted L-shaped cross section is attached to hide the opening of the line gutter, and the protrusion of the removable cover is The plate is curved upward and brought into contact with the inner surface of the upper part of the line gutter, and the lower edge of this removable cover is provided with a locking part that engages with the lower edge of the line gutter opening, so that the inside of the line gutter is A partition plate is removably installed across the partition plate holder and the removable lid.

Problems to be Solved by the Invention Although the earlier invention and the conventional example described above each have their own characteristics, there are also points that should be improved as follows.

(1) In the prior application, in order to prevent the conduit structure from falling off from the frame constituting the beam, stopper members protruding from both ends of the connecting member of the conduit structure are placed on the open side of the frame. It is inserted into the inside of the inwardly bent front end provided on the holder and is engaged and locked. This insertion work was troublesome because the connecting member had to be curved so as to reduce the width during insertion.

In addition, since the partition wall that divides the wiring passage within the conduit structure is formed integrally with the connecting member,
It was inconvenient to insert thick diameter wiring cables.

Furthermore, since the free ends of each fastening element that opens and closes in a double-door shape, which serves as a lid for the conduit structure, are fitted, there is a risk of separation when an external force is applied.

(2) When attaching the cover plate to the casing in Conventional Example 1, insert the lateral groove of the end of the cover plate into the leading edge of each cover piece at one extending end of the casing in a fitted state; In this state, it is necessary to push the lid plate and insert it sequentially along the longitudinal direction of the housing.

For this reason, a long space must be secured at least one end in the longitudinal direction of the housing to accommodate the cover plate before insertion.

In addition, especially in the case of a long case with a long wiring route, it is not possible to easily insert the cover plate only by pushing it from one end side, and it is necessary to insert the cover plate into the case so that the insertion does not stagnate or the engagement does not disengage. It may be necessary to pull out the distal end of the inserted cover plate midway in the longitudinal direction of the body, making the attachment work difficult.

(3) When attaching the above-mentioned wiring gutter to the connecting metal fitting in Conventional Example 2, insert the recess of the wiring gutter at one end of the connecting metal fitting into the convex part of the end of the connecting metal fitting in a fitted state, In this state, it is necessary to push the wiring gutter and insert it sequentially along the longitudinal direction in which the connecting fittings extend. Therefore, problems similar to those of the prior art example 1 described above arise.

(4) When attaching a removable cover to the line gutter in Conventional Example 3, either insert it from one side where the line gutter extends, as in the case of Conventional Examples 1 and 2 above, or
With the locking part of the removable lid locked to the lower bent edge of the line gutter, the upper part of the removable cover is rotated to insert the protruding plate into the line gutter.

For this reason, the former method causes the same problems as in the above-described conventional examples 1 and 2, and the latter method requires a large space along the longitudinally adjacent portion where the line gutter extends.

Therefore, the present invention aims to provide a wiring frame that can solve these problems.

Means for Solving the Problems The gist of the present invention is that a recess 2 in a frame 1 has a support piece 3 protruding from the open end and has a lip groove shape in cross section.
This wiring frame is assembled into an inner frame 4 and an outer frame 9, which are separately formed from an elastic resin material, and the inner frame 4 is attached to the opening side of both side plates. It has a substantially U-shaped cross section with a slope that widens toward the end, and the both side plates have an outer groove 5 on the outer surface adjacent to the opening end and an inner groove 6 on the inner surface of the intermediate part, each extending along the longitudinal direction of the wiring frame. The outer frame 9 has a substantially U-shaped cross section, and a protruding strip 11 is provided on the outer surface of both side plates adjacent to the opening end in a manner extending along the longitudinal direction of the wiring frame. The outer frame 9 has an opening that extends from the inner frame 4.
The convex strip 11 is fitted and locked into the inner groove 6 of the inner frame 4, and the inner frame 4 is inserted into the recess 2 with the bottom plate facing the opening of the frame 1. The outer groove 5 is press-fitted and locked to the support piece 3, and the assembled inner frame 4 has an outer frame whose outer side plate is restrained by the support piece 3 of the frame 1 and whose inner side includes the convex strip 11. 9
It is pressed and clamped outward by the side plate of the
The inner frame 4 is a wiring frame in which a partition plate 8 for dividing a passage within the wiring frame is detachably attached to the inner surface of the bottom plate.

Embodiments Hereinafter, this invention will be described in detail based on illustrated embodiments.

The frame 1 to which the wiring frame of this invention is attached is:
For example, it is provided on the legs or back panel of an OA desk, and its longitudinal direction extends vertically or horizontally.
Its cross-sectional shape is formed into a lip-groove shape as shown in the figure. That is, the frame 1 has a rectangular recess 2 formed therein with one side (hereinafter referred to as the front side) into which the wiring frame is inserted open and the remaining three sides covered by walls. Support pieces 3, 3 are protruded from the opening end so as to face each other inwardly.

The wiring frame is constructed by assembling together an inner frame 4 and an outer frame 9, which are each formed separately from an elastic (flexible) resin material. The internal space of the frame 1 forms a continuous rectangular wiring passage along the longitudinal direction of the extension of the frame 1, and the wiring passage is divided as appropriate by attaching removable partition plates 8 to the inner frame 4. I have to.

The inner frame 4 is formed into a gutter-like body with a substantially U-shaped cross section, with the opening sides of both side plates raised from the bottom plate becoming slopes that widen toward the end. On both sides of the inner frame 4, the frame 1 is attached to the outer surface adjacent to the opening end.
An outer groove 5 that elastically fits and locks with the support piece 3 is recessed along the longitudinal direction, and an inner groove that fits and locks with the convex strip 11 of the outer frame 9, which will be described later, is provided on the inner surface of the intermediate portion. 6 is formed along the longitudinal direction.

Further, the central inner surface of the bottom plate of the inner frame 4 forms a raised surface projecting in a rectangular shape toward the opening side, and a pair of left and right holding pieces 7, one of which is short and the other of which is somewhat long, integrally project from the raised surface. I'm letting you do it. This clamping piece 7 is formed so that its short end is bent slightly inward so that it can be elastically clamped against the partition plate 8.

The partition plate 8 has a thickness that is press-fitted and held between the holding pieces 7 of the inner frame 4, and has the same width so as to extend along the wiring path formed by the inner frame 4 and the outer frame 9. It is a band-shaped plate, and when the partition plate 8 is inserted into the clamping piece 7, the wiring passage is divided into two chambers, left and right, so that wiring cables 12 can be stored according to the purpose, and when this is removed, large diameter wiring cables can be stored. It consists of one room.

The outer frame 9 is formed into a gutter-like body with a substantially U-shaped cross section with both side plates standing up from the bottom plate. On both sides of the outer frame 9, protrusions 11 are provided on the outer surface adjacent to the opening end to fit and lock into the inner groove 6 of the inner frame 4.
is provided in a protruding manner extending along the longitudinal direction. In addition, flanges 10 are protruded from both sides of the bottom plate of the outer frame 9, forming a clog tooth shape as a whole, and the outer surface of the side plate of the outer frame 9 is formed into a slope that fits the inner surface of the opening side of the inner frame 4. It is configured to allow insertion in a sliding contact state and pressure contact after insertion.

When bonding the wiring frame having the above structure to the frame 1, the inner frame 4 is first fitted into the recess 2.

In this case, the inner frame 4 is arranged along the longitudinal direction of the frame 1 with the bottom plate facing the opening of the frame 1, and the lower half of the inner frame 4 on the narrow bottom plate side. Insert the part into the recess 2. When the entire inner frame 4 is pressed toward the frame 1 side in this state, the slope of the side plate formed in the upper half of the inner frame 4 will be pressed against the frame 1 side.
While sliding the tip of support piece 3 of
When the outer groove 5 aligns with the support piece 3, the side plate expands in diameter and the two are fitted and locked.

When a partition plate 8, which is also arranged along the longitudinal direction of the frame 1, is inserted from the front side into the clamping pieces 7 of the fitted inner frame 4 while being pressed, a partition plate 8 is inserted between the clamping pieces 7. The plate 8 is pressed and held. Thereby, a wiring passage divided into two compartments is formed within the inner frame 4, and for example, a power cable can be stored in one compartment and a signal cable can be stored in the other compartment.

Note that the wiring cable 12 to be stored is, for example, an OA
When the partition plate 8 is removed from the clamping piece 7 of the inner frame 4, the inside of the inner frame 4, which was previously divided into two chambers, becomes one wide-area room when the partition plate 8 is removed from the clamping piece 7 of the inner frame 4. , the above wiring can be easily and quickly changed.

Next, when attaching the outer frame 9 to the inner frame 4 fitted in the recess 2 of the frame 1, the opening of the outer frame 9 is placed opposite to the opening of the inner frame 4 so that the frame 1
be arranged along the longitudinal direction of the extension. In this state, when the outer frame 9 is inserted into the opening of the inner frame 4 and pressed, the protruding stripes 11 of the outer frame 9 are press-fitted while sliding against the inner wall surface of the inner frame 4, and the protruding stripes 11 are pressed into the inner frame. When aligned with the inner groove 6 of No. 4, both are fitted and locked.

The wiring frame made up of the inner frame 4 and the outer frame 9 fitted in the recess 2 of the frame 1 in this way has a side plate of the inner frame 4 whose outer side is restrained by the support piece 3 of the frame 1 and whose inner side is convex. Since the side plates of the outer frame 9 including the stripes 11 are pressed outward and clamped, a strong connection can be obtained without using screw means or other fastening means.

In addition, since the inner frame 4, outer frame 9, and partition plate 8 can all be attached by simply pushing them in from the front of the opening along the longitudinal direction of the frame 1, the attachment work is similar to that described above. In addition to being easier and more reliable than in the case of a conventional structure, attachment and detachment can be carried out even if there is no large space at one longitudinal end or in front of the wiring frame as in the case of a conventional structure. I can do it.

When removing the outer frame 9 from the opening position of the inner frame 4, hold the flanges 10 protruding on both sides of the outer frame 9 and pull the flanges 10 forward. The protruding portion 11 is the inner frame 4
Since the outer frame 9 escapes from the inner groove 6 of the outer frame 9, the outer frame 9 can be easily and quickly removed.

Furthermore, the above-mentioned wiring frame stores the wiring cable 12 inside and the inner frame 4 and the outer frame 9 are assembled in advance, and the wiring frame is installed in the longitudinal direction in which the frame 1 extends in the same way as in the above case. Alternatively, the inner frame 4 may be press-fitted into the recess 2 of the frame 1.

Effects of the invention Compared to the earlier invention mentioned above, the wiring frame of the present invention has improved workability because the outer surface of the inner frame has no protrusions and can be easily installed by simply press-fitting it into the recess of the frame. Since the partition plate is removable, it is possible to wire large-diameter wires, etc., and it can be used for a variety of purposes as a wiring frame for various devices.In addition, by assembling the inner frame and the separate outer frame, the frame can be easily recessed. It has the effect of being firmly attached to the facility.

In addition, the wiring frame of the present invention is installed by press-fitting it into the opening with the components of the wiring frame disposed along the longitudinal direction of the wiring path, so that the wiring frame is installed by press-fitting it into the opening. It can be assembled easily and reliably even if there is not a large space around it like in the case of a case.

Furthermore, the wiring frame of the present invention can be assembled by sequentially attaching the inner frame, partition plate, and outer frame, or by storing the wiring cable inside and pre-assembled the inner frame and the outer frame. This is convenient because the inner frame can be press-fitted and fitted into the recess of the frame depending on the conditions of use.
