Description

[Detailed description of the invention] [Field of industrial application] The present invention is applicable to cases where the edge of the desk top plate is partially cut out and cords such as telephone lines are inserted through the cutout. , relates to a device for protecting cords inserted through the incision.

[Conventional technology]

For office desks, reception counters, etc., telephone lines and cords of electrical appliances placed on the desk protrude from the edge of the desk top, which worsens the appearance. There was a problem with not being able to line up the desks side by side or place the desk tops close to the wall. Therefore, by partially cutting out the edge of the desk top plate and inserting the cord into the cutout, a protective cover was removably attached to the cutout. Measures are being taken to protect it and prevent deterioration of its appearance.

In that case, as a means to attach the protective cover to the incision, it is necessary to
The microfilm on which the specification and drawings attached to the application for No.
A letter-shaped fitting piece is fixed, and engagement holes are formed in the left and right side plates of the fitting piece, and protrusions are provided on the left and right outer surfaces of the approximately box-shaped protective cover. A device has been disclosed in which the fitting piece is engaged with an engagement hole.

In addition, in Japanese Utility Model Publication No. 51-51361, vertically extending engagement grooves opening upward are formed on the left and right inner surfaces of the incision, while vertically elongated projections are formed on the left and right outer surfaces of the protective cover. They have proposed a device that fits into the engagement groove of the cutout from above.

[Problem that the invention attempts to solve]

However, in the former method, the fitting piece is once fixed in the cutout of the desk top plate, and a protective cover is attached to it, which increases the number of parts and makes the entire device complicated. In addition, when removing the protective cover, it is removed by pulling it to the side, but when doing this, you can pinch both the top and bottom of the protective cover with your fingers and use the frictional force to remove it. Another problem was that the protective cover could not be pulled with great force because the protective cover had to be pulled.

On the other hand, the latter idea has the advantage that the protective cover can be easily removed by pushing upwards, but if the engagement between the protrusion of the protective cover and the engagement groove is loose, it may cause problems during transportation. There is a risk that it may come off easily if something touches it.Also, if it is a wooden desk top, it is relatively easy to form an engagement groove on the inner surface of the cutout, but if it is made of wood, it may come off easily. Since the interior of a desk top made of steel is hollow, it is difficult to form an engagement groove on the inner surface of a simple cutout, and it is difficult to apply it as is to a desk top made of steel. There was also a problem.

This invention makes it easy to attach and remove a protective cover attached to the cord insertion passage when a groove-shaped passage is formed on the side edge of a desk top plate made of a thin metal plate through which a cord such as a telephone line is inserted. Moreover, the purpose is to prevent it from coming off easily under normal conditions.

[Means for solving problems]

For this reason, in the present invention, a passageway for the insertion of telephone wires, etc., which is approximately rectangular in plan view and opens vertically and sideways, is recessed in the outer peripheral side edge of the desk top plate made of a thin metal plate, and the bottom part of the passageway is recessed. Vertically elongated engagement holes are bored on the left and right sides of the upper part of the side plates that constitute the passage, and substantially rectangular engagement holes are bored in the lower parts of the side plates that constitute the left and right side parts of the passage. A protective cover that can be freely fitted and removed is formed in a substantially box shape, a groove is cut in the upper and lower surfaces of the protective cover through which the telephone line, etc. is inserted, and an upper end surface of the left and right side plates of the protective cover is formed. A downward hook-shaped locking pawl is provided to protrude and engage in the vertically elongated engagement groove, and the lower outer surface of the right and left side plates of the protective cover is provided with a hook-like locking claw that is inserted into the vertically extending engagement groove and is provided with a hook-shaped locking pawl that extends downwardly and engages with the vertically elongated engagement groove. An engaging protrusion having a chevron shape in plan view is provided to protrude and be inserted between the left and right inner surfaces of the passage, the engaging protrusion is engaged with the substantially rectangular engaging hole, and the upper surface of the engaging protrusion is formed into a downwardly inclined surface that increases as the distance from the side plate of the protective cover goes downward.

〔Example〕

Next, an embodiment of the present invention will be described based on the drawings. In the drawings, reference numeral 1 indicates a pair of left and right legs 3
This is a reception desk which supports a desk top plate 2, and a curtain plate 4 is stretched between the rear ends of the left and right legs 3, 3. Cord insertion passages 8, which are generally rectangular in plan view and open vertically and laterally, are recessed at appropriate positions on the rear side edge and left side edge of the peripheral side edge of the desk top plate 2,
A telephone line 6 of a telephone 16 placed on the desk top plate 2 is inserted into the passage 8, and a substantially box-shaped protective cover 11 is attached to the passage 8.

Among the side plates forming the inner surface of the passage 8, the side plate 8a forming the bottom surface of the passage 8 is provided with longitudinal engagement slots 9, 9 on both left and right sides of its upper part. Side plates 8 forming the left and right inner side surfaces
b, 8b, substantially rectangular engagement holes 10, 10 are bored at their lower ends.

On the other hand, the protective cover 11 is dimensioned to fit snugly into the passage 8, and its top plates 11a, 11a' are formed with cut grooves 12, 12 through which the telephone line 6, etc. is inserted. At the same time, downward hook-shaped locking claws 13, 13 are bored into the upper end surfaces of the left and right side plates 11b, 11b to be engaged by falling into the long engagement holes 9, 9 in the bottom of the passage 8. The left and right side plates 11b, 11b have engaging protrusions 14, 14 projecting from the lower outer surfaces thereof, each having a chevron shape in plan view. In this case, the engagement protrusion 14 is formed such that the front surface 14a is a gently sloped surface, the back surface 14c is substantially perpendicular to the side surface of the protective cover 11, and the upper surface 14c is formed to be substantially perpendicular to the side surface of the protective cover 11.
4b is formed into a downwardly inclined inclined surface such that the protruding dimension of the protective cover 11 from the side plate 11b increases as it goes downward.

In the above configuration, the protective cover 11 is
To install it inside, as shown by the arrow in Figure 4,
The engaging protrusions 14, 1 resist the elasticity of the protective cover 11.
4 between the left and right inner surfaces of the passage 8, the hook-shaped locking pawl 13 is inserted into the locking elongated hole 9, and the hook-shaped locking pawl 13 is inserted into the locking elongated hole by pushing downward. It is sufficient if the engaging protrusion 14 is fitted into the engaging hole 10 from above at the same time as the engaging protrusion 14 is inserted into the engaging hole 9 and engaged. In that case, when the protective cover 11 is pushed in, the engaging protrusion 14 will be pushed between the left and right inner surfaces of the passage 8 due to elastic deformation of the protective cover 11, but since the front surface 14a of the protective cover 11 is gently sloped, While pushing is done smoothly,
Since the back surface 14c is substantially perpendicular to the side plate 11b, it engages within the range of height (H), thereby reliably preventing it from coming off in the attached state.

To remove the protective cover 11 that has been installed in reverse, the procedure is the reverse of the installation process. By pulling up the protective cover 11, the engaging protrusion 14 can be pulled out from the engaging hole 10, and the hook-shaped locking pawl 13 can be removed. Engagement long hole 9
All you have to do is disengage it and then pull it out toward you. In this case, the upper surface 14b of the engagement protrusion 14
Since it is formed into an inclined surface, the upward movement of the engaging protrusion 14 is guided, and when the protective cover 11 is pulled upward, it is done by hooking a finger on the lower surface and pulling it. It is possible,
Since the protective cover 11 can be pulled up with great force, the protective cover 11 can be removed extremely smoothly.

In this way, the passage 8 is formed by recessing the side plates of the desk top plate 2 inward, and the engagement elongated holes 9 and the engagement elongated holes bored in each side plate 8a, 8b constituting the inner surface of the passage 8 are formed. Since the protective cover 11 is attached using the hole 10, even if the desk top plate 2 is made of a thin metal plate, the telephone line 6 can be attached without increasing the number of parts.
etc., and the structure of the protective device can be simplified. Also, when attaching the protective cover 11, the hook-shaped locking claw 13
and an engaging protrusion 14 whose upper surface 14b is a sloped surface for locking and removal.
Since the protective cover 11 is designed to be disengaged by pulling upward, the protective cover 11 can prevent accidental slipping out by utilizing its own elastic force, but it is also extremely easy to attach and detach. It can be done easily.

In addition, an outlet 15 is fixed to the desk top plate 2,
Although the power cord 7 is connected through a hole drilled in the desk top plate 2, the power cord 7 for the outlet 15 may also be drawn out through the passage 8.

Further, a vertically longitudinal opening 17 with an appropriate left and right width (H1) is formed approximately at the center of the end surface of the leg body 3, and a wiring storage section 18 is formed at the back side of the opening 17, and the opening 17 is combined with the opening 17. It is closed with a lid body 19 made of resin. The lid 19 is configured to be able to be detachably engaged with the opening 17, and has a front plate 19' of the lid 19 at both upper and lower ends for pulling out a cord such as a telephone line 6. Notch slots 20, 20 are formed. Furthermore, cut grooves 21 communicating with the opening 17 are formed at both upper and lower ends of the side plates of the leg body 3, and cords such as the power line 7 of the wiring storage portion 18 are drawn out from the cut grooves 21.

[Functions and effects of the idea]

The present invention is constructed as described above, and the protective cover 11 has a hook-shaped locking claw by pushing the engaging protrusion between the left and right inner surfaces of the passage against its elasticity and then pushing it downward. is engaged with the vertically elongated engagement hole, and the engagement protrusion is engaged with the substantially rectangular engagement hole, respectively, so that they are permanently attached. Since the upper surface of the engagement protrusion is formed into a downwardly inclined surface, by once pulling it upward from the attached state, the engagement between the engagement protrusion and the hook-shaped locking pawl is released, and the protective cover is removed. It will be pulled out in front.

When attaching and detaching the protective cover, since the protective cover is first pushed in from the side and then pushed downward, a large force can be applied to the protective cover, making it easy to attach. To remove the protective cover, put your finger on the underside of the protective cover, pull it upward, and then pull it out to the side. Since a large force can be applied to the upward pull, it is easy to disengage the protective cover. This is easy to do, and once pulled upward, the engaging protrusion is only in contact with the inner surface of the passage, so it can be easily pulled out with a light force.

Therefore, according to the present invention, although the protective cover itself can be reliably installed in a state where it cannot be removed by using its own elastic force, it has the effect that it can be attached and detached extremely easily. In addition, since the protective cover is attached using the engagement hole drilled in the side plate that forms the inner surface of the passage, it is sufficient to simply attach the protective cover even if the desk is made of a thin metal plate. It also has the effect of simplifying the structure when protecting telephone lines and the like.
