According to the above-described configuration, by configuring the base 1 and the clamp 2, a plurality of types of the clamps 2 having different dimensions are prepared, so that it is possible to cope with various situations in which the outer diameter and the number of cables are different. Since the base 1 can be shared, the cost can be reduced and the economic efficiency can be improved as compared with a case where a plurality of types of the entire cable holding member are prepared. In addition, when the dimensions need to be changed due to an increase in the number of cables after the installation, it can be dealt with only by replacing the clamp 2, and there is no need to remove the base 1 from the installation surface. Performance can be improved. Furthermore, if an appropriate clamp is prepared, it is possible to hold not only the cable but also the piping material, and to cope with a change in the direction of the cable without removing the base 1 from the construction surface.
[0025]
Further, if the clamp 2 is moved to the open position, the cable can be taken in and out between the clamp 2 and the base 1, and it is not necessary to remove the clamp 2. Therefore, it is necessary to remove the clamp 2 when taking in and out the cable. The workability is improved as compared with the case where there is. Further, in the open position, the engagement of the projection 25 with the first through hole 12b prevents the clamp 2 from coming off, so that the clamp 2 can be prevented from being lost.
[0026]
It should be noted that the base 11 may be attached using a double-sided adhesive tape or an adhesive instead of being screwed to the construction surface.
[0027]
By the way, in the conventional cable holding member, the cable holding member that can easily hold the cable generally has a problem that the cable easily falls off, and the cable holding member that does not easily fall off the cable generally has troublesome work of holding the cable. In view of this, the present inventor has proposed a cable holding member shown in FIGS. 4 and 5 as a cable holding member that can easily hold a cable and that does not easily fall off the cable, separately from the above-described cable holding member. are doing.
[0028]
The cable holding member 3 is made of, for example, a synthetic resin such as nylon, and has a base 31 fixed to a construction surface, a cable holding piece 34 for holding a cable (not shown), and the cable holding piece 34 separated from the base 31. A biasing spring piece 33 for urging in the direction, and a cable holding piece 34 abutting against the cable holding piece 34 when the cable holding piece 34 is pushed in so as to approach the base 31 against the spring force of the biasing spring piece 33, and the cable is pressed. After being deformed into an enclosing shape, a hook-shaped piece 32 that locks the cable holding piece 34 and inhibits deformation is continuously and integrally provided.
[0029]
More specifically, the base 31 has a rectangular flat plate shape, and has screw insertion holes 31a for screwing to a construction surface, penetrating from the front and back, and is fixed with the back surface facing the construction surface. The hook-like pieces 32 project from both ends of the surface of the base 31 and are bent in directions in which the tips approach each other. The biasing spring piece 33 is formed in a rhombus shape, has elasticity in a diagonal direction, and is connected to the base 31 between two hook-shaped pieces 32. The cable holding piece 34 is formed in a U-shape in which an intermediate portion is formed to be thin, and can be bent so as to change the distance between both ends. The convex side of the intermediate portion is connected to the biasing spring piece 33. ing. A notch 34 a is provided on the outer surface of the tip of the cable holding piece 34. In addition, an inclined surface is provided on the surface of the hook-shaped piece 32 on the side away from the base 31 at the front end, the thickness of the hook-shaped piece 32 decreasing as it approaches the tip.
[0030]
In the state shown in FIGS. 4 and 5, both ends of the cable holding piece 34 are located on opposite sides of the base 31 with the tip of the hook-shaped piece 32 interposed therebetween. In order to hold the cable, the cable is introduced between both ends of the cable holding piece 34, and then the cable holding piece 34 is pressed in such a manner as to approach the base 31 against the spring force of the biasing spring piece 33. Then, the outer surfaces of both ends of the cable holding piece 34 are guided by the inclined surface at the front end of the hook-shaped piece 32, so that the cable holding piece 34 bends so as to bring both ends closer. When the cable holding piece 34 is further pushed in, the cable holding piece 34 returns as shown in FIG. 6, and the tip of the hook-shaped piece 32 engages with the notch 34 a of the cable holding piece 34, and the base of the cable holding piece 34. Movement away from 31 is prohibited. At the same time, the cable holding piece 34 is held so that both ends do not separate by contacting the hook-shaped pieces 32 at both ends. Here, both ends of the cable holding piece 34 are opposed to each other in a state where the tips of the hook-shaped pieces 32 are engaged with the notches 34 a of the cable holding piece 34 (hereinafter referred to as “closed state”). Each has a projection 34b protruding therefrom. The distance between the protrusions 34b at both ends of the cable holding piece 34 in the closed state is set to be sufficiently smaller than the outer diameter of the cable to be used, and the protrusion 34b prevents the cable from falling off.
[0031]
In order to return from the closed state shown in FIG. 6 to the state in which the cable shown in FIG. 4 can be taken in and out (hereinafter referred to as an “open state”), a force is applied so that both ends of the cable holding piece 34 are brought close to each other, The cable holding piece 34 is moved in a direction away from the base 31 while applying a force so that the tips of the hook-shaped pieces 32 are separated from each other to release the engagement between the notch 34a and the tip of the hook-shaped piece 32. Then, both ends of the cable holding piece 34 are separated from each other again so that the cable can be taken in and out.
[0032]
According to this configuration, it is possible to easily hold the cable in the closed state only by applying a pressing force to the cable introduced between both ends of the cable holding piece 34 in the open state. Further, since the closed state is not easily returned to the open state, it is possible to prevent the cable from falling off.
[0033]
Further, the present inventor has proposed another type of a cable holding member as shown in FIG. 7 as a cable holding member capable of easily holding the cable and preventing the cable from falling off. Hereinafter, the vertical and horizontal directions will be described with reference to FIG.
[0034]
The cable holding member 4 is formed of a synthetic resin molded product such as nylon, for example, and has a base 41 fixed to the construction surface and a hook-like shape protruding from the base 41 and having a tip approaching the base 41. The hook portion 42, the first protrusion 44 projecting from the tip of the hook portion 42 toward the base 41, and intersecting with the projection direction of the first protrusion 44 from the tip of the hook portion 42. A second protrusion 45 protruding in a direction approaching the connecting portion between the hook portion 42 and the base portion 41, and a first protrusion 44 protruding from the base portion 41 and having a front portion. A spring piece 43 that is located between the second projection 45 and the projection 45 and has elasticity in the direction in which the second projection 45 projects.
[0035]
Hereinafter, the shape of each part will be specifically described with reference to FIG. The base 41 has a rectangular flat plate shape, and screw insertion holes 41a for screwing to a construction surface are provided in front and back, and are fixed to the construction surface with the back surface facing. The hook portion 42 is formed vertically from the right end of the surface of the base portion 41 and has a tip portion bent leftward to form a J-shape. The spring piece 43 is thinly formed from the left end of the base 41 in a direction approaching the tip of the hook part 42, is formed to be thin, has elasticity, and is capable of bending right and left. Further, the spring piece 43 is easily bent by bending a plurality of times in the thickness direction. A first protruding portion 44 protruding upward and a second protruding portion 45 protruding rightward are provided at the tip of the hook portion 42. The tip of the spring piece 43 is located near the right side of the first protrusion 44.
[0036]
In order for the cable holding member 4 to hold the cable, the cable is pushed along the spring piece 43 between the spring piece 43 and the first protrusion 44. Then, the spring piece 43 is deformed and the cable is introduced, and then the spring piece 43 returns to hold the cable. That is, it is only necessary to push the cable between the spring piece 43 and the first protrusion 44 along the spring piece 43, so that the cable can be easily held. Here, even if the spring piece 43 is pushed from the inside by the cable, the cable does not come off because the first protrusion 44 inhibits the outward bending of the spring piece 43. Further, the cable from below is prevented from entering the gap between the spring piece 43 and the first protrusion 44 from the lower side by the second protrusion 45. The gap between them is not opened by the cable. Therefore, the gap for taking in and out the cable is not opened unless force is applied to the spring piece 43 from the outside, and there is no possibility that the cable will fall off.
