Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to an indoor wiring cover for storing and covering electric wires laid indoors, particularly on the floor.

Technical background of the invention and its problems Conventionally, this type of indoor wiring cover has been provided with retaining parts through vertical rising pieces or directly on both upper surfaces of the base that is adhered to the floor etc. There is a structure in which locking portions provided at the lower edges of both side surfaces of a base body formed in a trapezoidal cross section and consisting of both side surface portions are engaged with engaging portions of the base body.

However, in this structure, the upper parts of both sides of the cover are formed as slopes that expand outward, but the lower part has a height equal to the thickness of the base body or the sum of the thickness of the rising piece. Only this part is formed as a surface perpendicular to the floor surface, creating a step between the floor surface and the slope. Therefore, when using a cart, etc., the wheels get caught on this perpendicular surface and the cart is lifted. Otherwise, there will be an inconvenience that it will not be possible to pass through, and when cleaning the floor surface, a corner will be formed between the floor surface and the vertical surface, making it difficult to clean.

Further, in Japanese Utility Model Application Publication No. 47-25997, a protrusion is formed on the base plate, and a recessed part opened to the outside is formed between the outer side of the protrusion and the outer end of the base plate, and a recess is formed on both sides of the lid body. A protrusion that engages with the recess is formed at the lower end, and lips made of soft synthetic resin that contact the floor are integrally formed at both lower ends of the lid body or at both ends of the board, and these lips connect the floor and the lid. A structure that does not create a step between the body and the body is described.

However, in the case of a structure in which lips are formed on both ends of the lid, when a person or object steps on the lid, both sides of the lid act in the direction of expanding outward, so the lip There is a problem in that the lip easily separates from the floor surface, and dust etc. can easily enter between the lip and the floor surface.

In addition, regardless of whether or not it has a lip, both sides of the lid are supported by surface contact with the protrusions of the substrate, so when a load is applied to the lid as described above, the lid There are disadvantages in that the protrusions tend to come off from the recessed portions of the substrate, and the lid and the substrate are easily disengaged from each other.

Further, Japanese Utility Model Application Publication No. 51-147297 describes a structure in which the side surfaces of the top cover are formed thick so that the side surfaces of the top cover rise continuously from the floor surface.

However, this structure has a drawback in terms of molding, such as distortion due to sinkage.

Purpose of the invention The present invention has been devised in view of the above-mentioned drawbacks.The present invention has been developed in such a way that the cover is bonded to the base so that it does not come off from the base even when a load is applied to the cover, and there is no molding problem. Both sides of the cover are formed so as to be continuous with the floor,
To provide a cover for indoor wiring that prevents the wheels of a cart from getting caught, eliminates the trouble of lifting the cart, and facilitates sweeping when cleaning the floor.

Summary of the invention The present invention provides a wire storage unit that has retaining pieces on both sides of a base plate that are inclined upwardly and inwardly, and that has an open top surface between the retaining pieces on both sides and the base plate. , a top surface part that covers the top surface of the opening of the electric wire storage section of the second base body, and a bottom part that expands downward from both side edges of the top surface part and extends in a straight line until the bottom end thereof is flush with the bottom part of the base body. An integral cover having both extending side surfaces and locking protrusions that removably engage the engaging piece of the base body on the upper and lower inner surfaces of the both side surfaces, and the cover is coupled to each other. According to
The floor surface and both sides of the cover are connected by a continuous slope with no steps, allowing the wheels of a trolley to pass through easily, making it easy to sweep the floor surface, and supporting the load. The cover is designed to reliably maintain the bonded state between the cover and the base body even when the cover is attached to the base body.

Embodiment of the Invention Next, the present invention will be described based on an embodiment shown in the accompanying drawings.

Reference numeral 1 denotes a long and thin base made of synthetic resin, which includes a base plate 2 that is adhered to the floor surface of the structure, and rising pieces that are formed in an inclined shape that expands upward from both sides of the base plate 2 to the outside. 3, and a retaining piece 4 which is connected in a slanted manner from the tip of the rising piece 3 toward the top inward, and the base plate 2, the rising piece 3, and the engaging piece. 4 forms an electric wire storage section 5 whose upper surface is open.

Reference numeral 6 denotes a cover integrally formed of synthetic resin, which includes an upper surface portion 7 that covers the upper surface of the opening of the wire storage portion 5 of the base body 1, and a cover that expands downward from both side edges of the upper surface portion 7 and covers the substrate of the base body 1. It is formed by both side parts 8 having a lower end part 8a extending linearly to the same plane as the lower surface of the part 5, and the inner surface of the side part 8 has locking parts 9 and 10 integrally attached to the upper part and the lower part. Between the locking protrusions 9 and 10, an engagement recess 11 is formed which opens inward and detachably engages the engagement piece 4 of the base body 1.

Note that an adhesive tape or the like is attached to the lower surface of the base portion 5 for fixing the base body 1 to the floor surface of a structure or the like.

Next, when using it, first attach the adhesive tape to the base 1.
is attached to the floor surface of the wiring position, and the wire storage part 5 of this base 1 is attached.
After placing the electric wires inside and wiring them, the retaining piece 4 of the base body 1 is inserted into the engaging recess 11 between the locking protrusions 9 and 10 of the cover unit 6.
With the two parts engaged, the cover unit 6 is inserted from one end of the base body 1 and fitted.

As a result, the lower ends 8a of both side surfaces 8 of the integral cover 6 are in contact with the floor surface and are continuous with the floor surface without creating a step, and the angle formed with the floor surface is an obtuse angle much larger than 90°.

Therefore, the wheels of the trolley etc. move continuously from the floor to the side surface 8 of the cover unit 6, the top surface 7, the side surface 8, and the floor surface, and the wheels do not get caught on steps etc.
Easily uses trolleys, etc.

In addition, when cleaning, since the angle between the floor surface and the side surface 8 of the cover 6 is large and continuous, the cleaning tool does not reach all the way to the corner, and dust accumulates on both sides of the cover and becomes dirty. Never.

In addition, when a cart or a person rides on the cover as described above, the lower end 8 of both side surfaces 8 of the cover unit 6 receives the load.
a is in pressure contact with the floor surface, and the locking protrusion 9 on the upper part is stopped by the engagement piece 4 of the base body 1. Therefore, since both side parts 8 do not expand outward, the cover is closed. The unit 6 will not come off from the base 1.

Effects of the invention According to the invention, both side parts of the integral cover are formed to extend downward in a straight line from both side edges of the upper part, and the lower end thereof extends to the same plane as the bottom part of the base body. When the cover is set on the base, the lower ends of both sides of the cover are in contact with the floor, and the both sides of the cover are continuous with the floor, so there is no difference in level between them, and a large angle is created. Because it is continuous, there is no problem such as the wheels getting caught on the cover when using a trolley, etc., and when cleaning the floor, the angle is large and continuous without the floor and cover being integrated. Therefore, cleaning is easy, and there are no inconveniences such as cleaning tools not being able to reach the corners or not being able to clean the floor surfaces on both sides of the cover, which occur when there is a difference in level.

In addition, locking protrusions are formed on the top and bottom of the inner surface of both side surfaces of the integrated cover, and the retaining piece of the base body is engaged between the upper and lower locking protrusions, so that when the cover is subjected to a load from above, The locking protrusion on the upper part is securely held in the retaining piece, and the lower ends of both side parts are pressed against the floor surface, and both side parts are engaged by the frictional connection between the lower ends and the floor surface. This prevents the cover from expanding outward so as to come off the piece, and therefore the combined state of the cover and the base can be reliably maintained even if a load is applied from above.

Furthermore, by extending both side parts of the cover in a straight line and making the lower end contact the floor surface, both side parts and the floor surface can be continuous, so both side parts can be formed to be particularly thick. Unlike those that are continuous with the floor surface, there are no molding problems such as distortion in the thick part.
