Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crimping rod which is held between walls by a tension force and a crimping shelf using the crimping rod.

[0002]

2. Description of the Related Art A crimping rod for holding a rod urged in the extension direction between wall surfaces with a tensioning force for hanging an object in a place where nails or wood screws cannot be used, for example, in a closet or a corridor. Is widely known.

[0003]

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

Some crimping rods are of a type in which the tension force is adjusted by having a structure in which the rod body is inserted into the outer cylinder so as to be able to move forward and backward by a screwing means with a biasing force in the extending direction. (Representative publicly known example is Shoko Shou 5
6-878), in this case, there was a problem that the screwing of the rod body was loosened in the shrinking direction due to vibration and the like, and finally it slipped down from the wall surface.

[0005]

SUMMARY OF THE INVENTION The present invention is intended to provide a crimping rod and a crimping shelf using the crimping rod, which solves the problems of the prior art as described above. Two inventions are disclosed.

(First Invention) In the crimping rod of the present invention, a pair of contact members having one side as a contact surface for the wall surface and the other side as a tapered surface are prepared, and the tapered surface is used as the contact surface. The contact member is slidably provided on both ends of the crimping rod.

(2nd invention) The crimping rod of the present invention is an crimping rod comprising an outer cylinder and a rod body which is inserted into the outer cylinder by a screwing means so as to be able to advance and retreat with a biasing force in the extending direction. A holding member that rotatably holds the crimping rod is provided at one end or both ends of the pressure-bonding rod, and a ratchet mechanism is provided on the sliding surface of the crimping rod and the holding member to allow only rotation in the extension direction of the crimping rod when the two are in close contact with each other. Consists of.

(Third Invention) The present invention relates to a crimping shelf using a crimping rod having the requirements of the first and second inventions described above, and includes an outer cylinder and an extension direction in the outer cylinder. In a crimping rack provided with a plurality of crimping rods that are inserted by a screwing means so as to be able to advance and retreat with a force, a holding member that rotatably holds the ends of the plurality of crimping rods is provided, and each crimping rod is provided. The sliding surface of the holding member and the holding member are provided with a ratchet mechanism that allows only the rotation of the crimping rod in the extension direction when they are in close contact with each other, and one side is a contact surface to the wall surface and the other side is a tapered surface. A pair of abutting members are prepared, and the abutting member is slidably provided on the crimping rod and the holding member with the tapered surface serving as a contact surface.

[0009]

The operation of each of the above inventions is as follows (more specific operation will be mentioned in the embodiments). (First invention) In this invention, since the contact members having the tapered surfaces for contacting with the crimping rod are slidably provided at both ends of the crimping rod, the taper surface becomes thicker as it goes downward. If the abutting member abuts against the wall surface and the crimping rod is stretched and held, if an excessive load is applied to the crimping rod and it tries to slide down, its end slides on the tapered surface of the abutting member. As a result, it moves in the reduction direction, so
The urging force that pushes it back in the extension direction acts, resulting in stronger frictional resistance and the effect of preventing slip-down (see FIGS. 5 and 6).

(Second Invention) In the present invention, a holding member for rotatably holding the crimping bar is provided at an end of the crimping bar, and the crimping bar and the sliding surface of the holding member are adhered to each other when they are in close contact with each other. Since a ratchet mechanism that allows only rotation in the extension direction of the crimping rod is installed, if the screwing of the crimping rod tries to loosen in the shrinking direction due to vibration etc. when installing it between the wall surfaces of the crimping rod, it is prevented by the ratchet mechanism. On the other hand, when it is rotated in the extension direction, there is an effect that it can be rotated without trouble.

(Third invention) In this invention, since the crimping bar having the requirements of the first invention and the second invention is used in the crimping shelf, the respective effects of the first invention and the second invention are achieved. Will occur.

FIG. 1 is a sectional view of this crimping bar. The crimping rod is composed of an outer cylinder 10 and a cylindrical rod body 20 which is inserted into the outer cylinder so as to be able to move forward and backward. In this embodiment, a coil spring S is provided inside the rod body and inside the outer cylinder. Insert and
One end of the coil spring is fixed to the pin 12 of the outer cylinder 10, and a pin-shaped guide member 22 that is screwably engaged with the coil spring is provided inside the rod body 20 to remove the rod body from the outside. The cylinder is provided with an urging force in the extending direction so as to be movable back and forth by a screwing means. That is, in this mechanism, by rotating the rod body 20, the guide member 22 is screwed with the coil spring S fixed to the outer cylinder 10 to move the rod body 20 back and forth. Since it is supported by S, it is supported with elastic force. The mechanism itself is known from, for example, the above-mentioned Japanese Utility Model Publication No. 56-878.

Reference numeral 21 in the figure denotes an end member provided at one end of the rod body 20. The end member 21 is rotatably fitted at its tip end to the holding member 50, and a ratchet mechanism R2 is provided between the end member 21 and the end member 21 to allow only one-direction rotation when they are in close contact with each other.

FIG. 2 shows the details of this relationship. The ratchet mechanism R2 has the end member 2 of the rod body 20.
A rotary ratchet type gear 22 provided on the end face of 1.
This is realized by the engagement of a rotary ratchet type gear 52 provided on the bottom of the bottomed cylindrical holding member 50, and the direction of blocking the rotation is set to the rotational direction for reducing the crimping rod.
Incidentally, reference numerals 23 and 53 in the figure denote an annular projection and an annular groove for preventing the end member 21 and the holding member 50 from coming off.

Reference numeral 60 in the drawing denotes an abutting member to which the above holding member 50 should be connected. This contact member 60 has one side as a contact surface for the wall surface W and the other side as a tapered surface T2.
The holding member 50 slides with respect to the tapered surface T2 by slidingly fitting the slider 51 provided at one end of the holding member 50 into the sliding groove 61 provided on the tapered surface T2 side. It is provided freely (the retaining mechanism for both is not shown). Reference numeral 62 in the figure denotes a rubber plate interposed between the contact member 60 and the wall surface W.

Next, reference numeral 11 in the drawing is an end member provided at one end of the outer cylinder 10. This end member 11
The tip of the ratchet is freely rotatably fitted to the holding member 30, and a ratchet mechanism R1 is provided between the two so as to allow only one-direction rotation when they are in close contact with each other. Since the details of the relationship between the ratchet mechanism R1 and the end member 11 and the holding member 30 are the same as those of the end member 21 and the holding member 50, the description thereof will be omitted here.

Reference numeral 40 in the drawing denotes an abutting member to which the above-mentioned holding member 30 should be connected, and the relationship thereof is the holding member 5 described above.
This is similar to the case of 0 and the contact member 60. That is, the contact member 40 has one side as a contact surface for the wall surface W and the other side as a tapered surface T1, and the slider 31 provided at one end of the holding member 30 has a tapered surface T1. The holding member 30 is slidably provided on the tapered surface T2 by being slidably fitted in the sliding groove 41 provided on the side. Reference numeral 42 in the figure denotes a rubber plate interposed between the contact member 40 and the wall surface W.

In the above embodiments, the ratchet mechanism is provided at both ends of the crimping rod, but it is needless to say that the action and effect of the present invention can be obtained even if only one end is provided. is there.

The operation of the crimping rod of the above embodiment is as follows. First, in order to fix the crimping rod to the wall surface, the rod body 20 is rotated with respect to the outer cylinder 10 to adjust the entire length of the crimping rod to be slightly longer than between the wall surfaces W, so that both are resisted against the urging force. After pushing it in between the wall surfaces W, W and then separating it, press it with a tension force between the wall surfaces, or
Alternatively, after adjusting the entire length of the crimping rod to be slightly shorter than between the wall surfaces W and W, positioning the crimping rod between the wall surfaces W and W, and then rotating it in the extension direction to crimp between the wall surfaces. It is performed by any means.

Once fixed between the wall surfaces, both ends (specifically, the holding members 30 and 50) of the crimping bar are slidably provided on the abutting members 40 and 60, respectively, so that the tapered surface T1 is formed. If the contact member abuts against the wall surface W in a direction in which T2 becomes thicker as it goes downward and the crimping rod is stretched and held, when an excessive load H is applied to the crimping rod and the crimping rod tries to slide downward. Since its end moves in the contraction direction as a result of sliding on the tapered surface of the abutting member, stronger frictional resistance is generated due to the biasing force that pushes it back in the expansion direction, and slipping is prevented. (See FIGS. 3 to 6).

Further, the outer surface of the crimping rod 10, both ends of the rod body 20 (specifically, the end members 11 and 21), and the sliding surfaces of the holding members 30 and 50 are only rotated in the extension direction of the crimping rod. Since the ratchet mechanism R1 and R2 that allows it is provided,
If vibration of the crimping rod tries to loosen it in the shrinking direction, it is prevented by the ratchet mechanism.On the other hand, if it is rotated in the extension direction when the crimping rod is mounted between the wall surfaces, there is no problem. Can rotate. In addition, since the end member is not in close contact with the holding member with a biasing force except when it is pressure-bonded to the wall surface, it is not possible to easily rotate the two members in the opposite directions against the ratchet mechanism. Needless to say.

7 to 9 are views showing an embodiment of the third invention.

[0030]

The present invention having the above construction has the following unique effects. When an excessive load is applied to the crimping rod and it tries to slide down, the end of the crimping rod slides on the tapered surface of the abutting member and moves in the contracting direction, so push it back in the expanding direction. Since such a biasing force acts to generate stronger frictional resistance and prevent slipping off, a safe and reliable crimping bar (crimping shelf) is realized (first invention and third invention).

For the same reason as described above, reliable crimping can be expected without excessively increasing the tension of the crimping rod, so that the wall surface is prevented from being damaged by the crimping force.

The sliding surface of the crimping rod and the holding member is provided with a ratchet mechanism which allows only the rotation of the crimping rod in the extension direction when they are in close contact with each other. When the screwing of is trying to loosen in the contracting direction, it is prevented by the ratchet mechanism, while when it is rotated in the extending direction, it has the effect that it can rotate without hindrance, so permanent crimping is performed. A safe and reliable crimping rod (crimping shelf) that lasts is realized (first invention and second invention).
