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 wall surfaces with a tensile force, and a crimping shelf using the same.

[0002]

2. Description of the Related Art For example, a crimping rod for holding a rod urged in an elongating direction between wall surfaces with a tension force to suspend 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-mentioned crimping bar has the following problems. First, as a general problem of the crimping rod, since the holding between the wall surfaces is mainly based on the frictional resistance due to the tension force, when an excessive load is applied, for example, when a heavy object is hung on the crimping rod, this load is applied. However, there is an inconvenience of overcoming the frictional resistance and causing the pressure rod to slip down from the wall surface.

There is a type of a crimping rod in which a rod body is inserted into an outer cylinder so as to be able to advance and retreat by a screwing means with an urging force in an extending direction so as to adjust the tension force. (Typical known examples are
In this case, there is a problem that the screwing of the rod body is loosened in the reducing direction due to vibration or the like and finally slips off from the wall surface.

[0005]

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

In the figure, reference numeral 21 denotes an end member provided at one end of the rod 20. The end member 21 has its tip freely rotatably fitted to the holding member 50, and a ratchet mechanism R2 that allows only one direction rotation when the end member 21 is in close contact with the holding member 50 is provided.

FIG. 2 shows the details of this relationship. The ratchet mechanism R2 is an end member 2 of the rod 20.
A rotating ratchet-type gear 22 provided on one end face;
This is realized by the engagement of a rotary ratchet-type gear 52 provided at the bottom of the bottomed cylindrical holding member 50, and the direction in which the rotation is blocked is set to the direction in which the crimping rod is reduced.
Reference numerals 23 and 53 in the drawing denote annular projections and annular grooves for preventing the end member 21 and the holding member 50 from coming off.

Reference numeral 60 in the figure denotes a contact member to which the above-mentioned holding member 50 is to be connected. The contact member 60 has one side as a contact surface with the wall surface W and the other side with a tapered surface T2.
By sliding the slider 51 provided at one end of the holding member 50 into the sliding groove 61 provided on the tapered surface T2 side, the holding member 50 slides on the tapered surface T2. It is provided freely (the two retaining mechanisms are not particularly shown). Reference numeral 62 in the drawing denotes a rubber plate interposed between the contact member 60 and the wall surface W.

Reference numeral 11 in the figure denotes an end member provided at one end of the outer cylinder 10. This end member 11
A ratchet mechanism R1 is provided between the two so as to freely rotate in one direction when the tip thereof is freely rotatably fitted to the holding member 30. Since the details of the relationship between the ratchet mechanism R1, 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 is omitted here.

In the figure, reference numeral 40 designates a contact member to which the above-mentioned holding member 30 is to be connected.
This is the same as the case of 0 and the contact member 60. That is, the contact member 40 has one side as a contact surface with 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 is formed into a tapered surface T1. The holding member 30 is slidably provided on the tapered surface T2 by slidingly fitting the sliding groove 41 provided on the side. Reference numeral 42 in the drawing denotes a rubber plate interposed between the contact member 40 and the wall surface W.

In the above embodiment, the ratchet mechanism is provided at both ends of the crimping rod. However, it is needless to say that the function 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, the fixing of the crimping rod to the wall surface is performed by rotating the rod body 20 with respect to the outer cylinder 10 to adjust the entire length of the crimping rod slightly longer than between the wall surfaces W and W, and to hold both against the urging force. After being positioned between the walls W and W while pushing it in, press it apart and press it against the wall with a tensile force,
Alternatively, adjust the total length of the crimping rod slightly shorter than between the wall surfaces W and W, position the crimping rod between the wall surfaces W and W, and then rotate it in the extension direction to perform crimping between the wall surfaces. This is performed by any means.

Once fixed between the wall surfaces, both ends of the pressure rod (specifically, holding members 30 and 50) are slidably provided on the contact members 40 and 60, respectively, so that the tapered surface T1 If the contact member is brought into contact with the wall surface W in a direction in which the thickness becomes smaller as T2 goes downward, and the crimping rod is stretched and held, an excessive load H is applied to the crimping rod, and the crimping rod is slid downward. As the end moves in the contracting direction as a result of sliding on the tapered surface of the contact member, a stronger frictional resistance is generated by the urging force to push it back in the extending direction, thereby preventing slipping down. (See FIGS. 3 to 6).

Further, only the rotation in the extension direction of the crimping bar is applied to the outer surface of the crimping bar, both ends of the bar 20 (specifically, the end members 11 and 21) and the sliding surfaces of the holding members 30 and 50. Since ratchet mechanisms R1 and R2 are provided,
The ratchet mechanism prevents the crimping rod from loosening in the shrinking direction due to vibrations, etc., but does not hinder the rotation of the crimping rod in the extension direction when it is mounted between the wall surfaces of the crimping rod. Can rotate. Note that the end member is not in close contact with the holding member with a biasing force except at the time of press-fitting to the wall surface, so that it is possible to easily rotate both members in the opposite direction against the ratchet mechanism. Needless to say.

FIGS. 7 to 9 show an embodiment of the third invention. The third invention relates to a crimping shelf using the crimping bar having the requirements of the first and second inventions, and its main part is almost the same as the crimping bar in the embodiment of the first and second inventions.

[0030]

The present invention having the above configuration has the following specific effects. If an excessive load is applied to the crimping rod and it slides down, its end moves in the contracting direction as a result of sliding on the tapered surface of the abutting member. Such an urging force acts to generate stronger frictional resistance and prevent slip-down, so that a crimping rod (crimping shelf) that is safe and secure is realized (first and third inventions).

For the same reason as described above, reliable pressure bonding can be expected without excessively increasing the tension force of the pressure bonding rod, thereby preventing the wall surface from being damaged by the pressure bonding force.

Since 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, the crimping rod is attached to the wall of the crimping rod due to vibration or the like when it is mounted between the wall surfaces. If the screw is loosened in the contraction direction, it is prevented by the ratchet mechanism.On the other hand, if the screw is rotated in the extension direction, it can be rotated without any trouble.
