Description

  The present invention relates to a crimping bar and a crimping shelf that are held with a tensile force between wall surfaces, and more particularly to an improved creation of the crimping structure.

  For example, in order to hang things in places where nails and wood screws cannot be used, such as in closets and corridors, a rod and a contact member to a wall surface that is arranged with an urging force in the extending direction at both ends of the rod There are widely known crimping bars that are fixed with a tension force between the wall surfaces and a crimping shelf provided with a plurality of these.

  However, the above crimp bar has the following problems. First, as a general problem of the crimping rods, since the holding between the wall surfaces is mainly based on the frictional resistance due to the tensile force, this load is applied when an excessive load is applied, for example, the weight of the object hung on the crimping rod is heavy. However, there is an inconvenience that the frictional resistance is overcome and the crimping rod slides down from the wall surface.

  In addition, there is a type of crimping rod that adjusts its tension force by adopting a structure in which a rod body is inserted into an outer cylinder with an urging force in an extending direction so as to be able to advance and retreat by a screwing means (typical) As a known example, Patent Document 1), in this case, there has been a problem that the screwing of the rod body is loosened in the shrinking direction due to vibration or the like and finally falls off the wall surface.

  As a known invention in which the above problems have been solved, there is a crimping bar described in Patent Document 2. 13 to 15 are diagrams showing details of the crimping bar. The rod body P of this crimping bar is composed of an outer cylinder 40 and an inner cylinder 41 which is inserted into the outer cylinder so as to be able to advance and retract. A coil spring S is inserted into the inner cylinder and the outer cylinder, and this coil spring. Is fixed to the pin 43 of the outer cylinder 40, and a pin-shaped guide member 42 is provided inside the bar body 41 so as to be threadably engaged with the coil spring, whereby the bar body is extended with respect to the outer cylinder. It is provided so as to be able to advance and retract by screwing means with a biasing force in the direction. That is, in this mechanism, by rotating the rod P, the inner cylinder 41 advances and retracts when the guide member 42 is screwed with the coil spring S fixed to the outer cylinder 40. In this case, the guide member 42 Since it is supported by the coil spring S, it is supported with an elastic force.

  Reference numeral 60 in the drawing denotes an abutting member, which is connected to the rod body 30 via the end member 50. The abutting member 60 has one side as an abutting surface against the wall surface W and the other side as a tapered surface that is separated from the wall surface as it goes downward. A sliding surface provided at one end of the end member 50 described above. The end member 50 is slidably provided with respect to the tapered surface by slidingly fitting the moving element 51 into the sliding groove 61 provided on the tapered surface side with a retaining means (not shown).

  This crimping bar is held between the wall surfaces W and W with a tensile force. Since each end member 50 is slidably provided on the contact member 60, when an excessive load is applied to the crimping rod and the end member 50 attempts to slide downward, the end portion of the end member 50 moves downward from the wall surface. As a result of sliding on the tapered surface of the abutting member that is spaced apart, it moves in the shrinking direction, so that the urging force that pushes it back in the extending direction causes a stronger frictional resistance and prevents slippage. (See FIGS. 14 to 15).

  As long as the crimping rod described in Patent Document 2 is assumed to be used within the design range, the wedge effect due to the tapered surface of the contact member has a remarkable effect of preventing the crimping rod from sliding down. However, if an excessive load exceeding the design range is applied to the central portion of the crimping rod and the rigidity of the crimping rod cannot withstand it, the crimping rod bends in the load direction as shown in FIG. There was a possibility of causing a phenomenon. In this case, since the slider 51 provided at one end of the end member 50 is slidably fitted to the abutting member 60 with a retaining means, the abutting member is pulled away from the wall surface as the crimping bar is bent. Problems arise.

  The crimping bar of the present invention was created in view of the above-mentioned problems of the prior art, and an object thereof is to provide a crimping bar that does not impair the tension even if it is bent by a load. That is, the crimping rod of the present invention includes a rod 1 and a crimping rod which is fixed with a tensile force between the wall surfaces by the abutting members 10 which are arranged at both ends of the rod body with an urging force in the extending direction. An end member 19 slidable up and down in the sliding path 12 of the contact member having tapered surfaces 13 and 14 that are separated from the wall surface as it goes is interposed between the end of the rod body and the contact member. The rod body holding portion 20 is used as the side, and the other side of the pin 21 projecting downward from the pin 21 and the other end of the end member facing the pin is used as a sliding contact point with respect to the opposing wall surface of the sliding path. The end member can swing within the sliding path with the pin as an axis by retreating the portion Y below the pin of the sliding contact point X on the other side toward the end of the crimping rod.

  Further, in this case, in the crimping shelf provided with a plurality of crimping rods that are fixed with a tensile force between the wall surfaces by the abutting members to the wall surfaces arranged with the urging force in the extending direction at both ends of the rod body 1, An end member 19 slidable up and down in the sliding path 12 of the contact member 10 having tapered surfaces 13 and 14 that are separated from the wall surface as it goes downward is interposed between the rod end and the contact member. The member has a rod body holding portion 20 on one side, and the other side of the end member opposed to the pin 21 projecting downward from the pin 21 is a sliding contact point with respect to the opposing wall surface of the sliding path. It is characterized in that the end member can swing in the sliding path with the pin as an axis by retracting the portion Y below the pin of the sliding contact point X on the other side of the end member toward the end of the crimping rod. A crimp shelf is also disclosed.

  According to the crimping rod of the present invention, the end member 19 that can slide up and down in the sliding path 12 of the contact member 10 having the tapered surfaces 13 and 14 that are separated from the wall surface as it goes downward is defined as the end of the rod 1. Since it is interposed between the abutting members, if the crimping rod is stretched and held, an excessive load is applied to the crimping rod, and if the end member tries to slide downward, the end member will reduce the tapered surface of the abutting member. As a result of sliding, it moves in the shrinking direction, so that an urging force is exerted to push it back in the extending direction, so that a stronger frictional resistance is generated and the sliding is prevented.

  On the other hand, the end member 19 has a rod body holding portion 20 on one side, and a pin 21 projecting downward from the end member 19 and the other side of the end member facing the pin on the opposite wall surfaces of the sliding path. Since the part Y and the portion Y below the pin of the sliding contact point X on the other side are retracted toward the end of the crimping rod, the pin can be swung in the slide path as an axis, so the rod body is temporarily bent However, as a result of the end member provided at its end swinging due to the bending, the entire length of the rod shortened by the bending is absorbed by the swinging of the end member. Therefore, the contact member is prevented from being pulled in a direction away from the wall surface with the bending of the crimping rod.

  Hereinafter, specific embodiments of the crimping rod of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a partially cutaway side view of the first embodiment of the crimping bar, with the middle omitted. This crimping bar comprises a rod body 1 consisting of an outer cylinder 2 and an inner cylinder 3 inserted into the outer cylinder so as to be able to advance and retreat. In this embodiment, a coil spring 5 is inserted inside the inner cylinder 3, One end of the coil spring is fixed to the pin 24 of the rotating body 22 of the rod body holding portion 20 of the end member 19 which will be described later, and a guide projection 23 that engages with the coil spring is formed in the inner cylinder 3. By providing, the rod body 1 (inner cylinder 3) is provided so as to be freely advanced and retracted by a screwing means with an urging force in an extending direction with respect to the end member. That is, in this mechanism, the coil spring 5 is also rotated by rotating the rotating body 22, and this coil spring is screwed with the guide protrusion 23 of the inner cylinder 3, so that the rod body 1 (inner cylinder 3) advances and retreats. In this case, since the rod body 1 (inner cylinder 3) and the end member 19 (rotating body 20) are supported by the coil spring 5, they are supported with an urging force in the extending direction. Reference numeral 4 in the figure denotes a wood screw that is screwed into the inner cylinder from the outer cylinder side in order to fix the inner cylinder 3 inserted in the outer cylinder 2 so as to be able to advance and retreat in an appropriate position.

  2-10 is a figure which shows the detail of the contact member 10 and the end member 19 which comprise the principal part of this invention. The abutting member 10 has a structure in which a rubber plate 11 that abuts against a wall surface is provided on the back surface, and an end member 19 is exposed on the front surface. A sliding path 12 for the end member 19 is provided in the abutting member 10, and the front and rear side walls of the sliding path are formed as tapered surfaces 13 and 14 that are separated from the wall surface as they go downward.

  The end member 19 has a rod body holding portion 20 on the upper side. In this embodiment, the rotating body 22 is rotatably held by the rod body holding portion of the end member on the inner cylinder 3 side of the rod body 1. The inner cylinder end is loosely fitted into the rotating body. Moreover, the outer cylinder end is inserted in the rod body holding part 20 of the end member 19 on the outer cylinder 2 side of the rod body 1 (see FIG. 1).

  A pin 21 slidably contacting the tapered surface 13 on the front side of the sliding path 12 of the end member 19 protrudes from the end member 19 at a position lowered from the rod body holding portion 20. Further, the other side of the end member 19 facing the pin 21 is a sliding contact portion X with respect to the tapered surface 14 on the rear side of the sliding path 12, and a portion Y below the pin is retracted toward the end of the crimping rod. ing. As a result, the end member 19 can swing in the sliding path 12 with the pin 21 as an axis.

  The pressure-bonding bar of the present invention having the above-described structure has a rod body having an end member 19 that can slide up and down in the sliding path 12 of the abutting member 10 having tapered surfaces 13 and 14 that are separated from the wall surface in the downward direction. Since it is interposed between the one end and the abutting member, if the crimping rod is stretched and held, if an excessive load is applied to the crimping rod and it tries to slide downward, the end member will be As a result of sliding on the taper surface, the taper surface moves in the contraction direction, so that an urging force for pushing it back in the extension direction works, and an effect of preventing a slipping-off by generating a stronger frictional resistance.

  On the other hand, the end member 19 has a rod body holding portion 20 on one side, and a pin 21 projecting downward from the end member 19 and the other side of the end member facing the pin on the opposite wall surfaces of the sliding path. Since the part Y and the portion Y below the pin of the sliding contact point X on the other side are retracted toward the end of the crimping rod, the pin can be swung in the slide path as an axis, so the rod body is temporarily bent However, as a result of the end member provided at the end swinging due to the bending (see FIGS. 5 to 7), the entire length of the rod shortened by the bending is absorbed by the swinging of the end member. Therefore, it is prevented that the contact member is pulled in the direction away from the wall surface due to the bending of the crimping rod, and when an excessive load is applied to the crimping rod and it tries to slide downward, the end member is As a result of sliding on the tapered surface of the abutting member, it moves in the shrinking direction, so that the urging force to push it back in the extending direction works, and there is an effect that a stronger frictional resistance is generated and slipping is prevented. (See FIGS. 8 to 10).

  FIG. 11 is a view showing a second embodiment of the bar 30 of the crimping bar according to the present invention. This crimping rod comprises a rod body 30 comprising an outer cylinder 31 and an inner cylinder 32 inserted into the outer cylinder so as to be able to advance and retreat.
