DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a strut pole and a crimp member for use in a strut shelf which are held with a tension between wall surfaces or between a ceiling and a floor, and more particularly to an improved creation of the crimp structure. .

[0002]

2. Description of the Related Art For example, as a means for installing a pole or a shelf in a place where nails or wood screws cannot be used, such as in a closet or a corridor, a crimping member urged in the direction of extension is stretched between wall surfaces and stretched. Strut poles and shelves that hold with force are widely known.

In this case, an end member provided at one end of a cylindrical rod body constituting a pole is projected outward with an urging force to provide a means for crimping between wall surfaces (for example,
In addition to the invention (for example, Japanese Utility Model Publication No. Sho 62-18789), a means for adjusting the amount of protrusion is provided.
No. 9688, No. 2-21990, No. 2-21
No. 955).

[0004] The above-mentioned known example includes a shaft (also 5) provided at the head of an end member (4 in FIG. 4 of Japanese Utility Model Publication No. 62-29688).
A stopper screw (similarly 51) having a screw groove on the outer periphery is provided with a retaining means (similarly 51) to fit non-rotatably and slidably, and a compression coil spring ( Similarly, the end member protrudes outward with respect to the top screw by interposing 6), and this top screw is provided on the crimping base (2) at the end of the rod (1). The invention discloses a means for adjusting the amount of protrusion by screwing the end member (also 21) into and out of the rod by rotating the end member.

[0005]

In the above invention, when the end member is rotated, the end member advances and retreats from the rod, and as a result, when the tension pole is held between the wall surfaces, the head of the end member is moved. The distance between the end member and the top screw is changed to adjust the amount of protrusion of the end member, which is a useful invention in this respect.

In this case, however, the amount of protrusion is adjusted by rotating the end member itself.
Before holding the strut pole between the walls,
After being held between the wall surfaces, there is an annoyance that a mechanism for rotating the surface of the end member that contacts the wall surface independently of the end member is indispensable.

Further, in the above invention, the crimping force on the wall surface is adjusted according to the degree of advance and retreat of the end member from the rod, so that the degree of advancement and retreat is represented by a scale so that the crimping force can be visually recognized. However, this function is effective only before the strut pole is held between the wall surfaces, and is ineffective after being held between the wall surfaces. In the above invention, when the tension pole is held between the wall surfaces, the end member stops at a predetermined position determined by the absolute distance between the wall surfaces, and even if it is rotated, the end member itself moves forward and backward. This is because the internal screw does not move forward or backward. Therefore, in this case, there was a problem that the user had to adjust the pressing force by intuition.

[0011]

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 6 are views showing a crimping member according to the present invention, and here, it is assumed that the crimping member is fixed to an end portion of a rod P1.

Reference numeral 7 in the figure denotes a crimping base, and an end member to be described hereinafter moves forward and backward with respect to the crimping base 7. In this embodiment, the crimping base 7 is illustrated as a synthetic resin cap having a concave portion 7A provided at one end and fitted to the end of the cylindrical rod P1 (see FIG. 1). The configuration is not limited to this, and for example, a rod P1
It is needless to say that an object which is integrated with the object can be supposed, and the object to be fixed is not limited to the rod, and may be directly fixed to, for example, a shelf board.

In the drawings, reference numeral 1 denotes an end member. In this embodiment, a cap 6 for contacting a wall surface is fitted at one end. The end member 1 has a configuration in which a shaft 3 protrudes from the back side of the flange-shaped head 2, and a first urging means for drawing the end member 1 toward the crimping base 7 side The shaft 4 is slidably inserted into the through hole 8, and the stopper 4 and the crimp base 7 provided at the end of the shaft 3 are provided.
This is realized by interposing a compression coil spring S1 therebetween. In this embodiment, the shaft 3 is not allowed to rotate with respect to the through hole 8 of the crimping base 7, and as a means therefor, the shapes of both are square in cross section.

Next, the second urging means for pushing out the end member 1 to the outside of the crimping base 7 includes a screw groove 9A on the outer periphery and a coma screw 9 having a through hole 9B in the center, and a head of the end member 1. Between the top screw 2 and the head 2 of the end member 1 and between the top screw 2 and the head 2 of the end member 1.
This is realized by interposing In this case, as means for preventing the top screw 9 from rotating with respect to the shaft 3,
Similarly to the above, the shape of the through hole 9B of the top screw 9 and the shape of the shaft 3 are square in cross section (see FIGS. 5 and 6).

The means for adjusting the amount of protrusion of the end member 1 from the crimping base 7 includes a rotary knob 10 having a thread groove 10A on the inner periphery between the head 2 of the end member 1 and the crimping base 7. It is realized by screwing outside the top screw 9. In this embodiment, a protruding piece 10 is provided around the rotary knob 10 to provide a clue for rotation.

Each of the above members is formed by sequentially inserting a compression coil spring S2, a coma screw 9 previously screwed into a rotary knob 10, a crimp base 8, and a compression coil spring S2 onto the shaft 3 of the end member 1. At the end of shaft 3 with screw 5
(See FIG. 1). In this embodiment, the head 2 of the end member is so arranged that the rotary knob 10 rotates smoothly between the head 2 of the end member 1 and the crimping base 8 when assembled.
And a concave portion 1A, 7B for rotatably holding both ends of the rotary knob on the rotary knob side of the pressing base 8.

Next, the operation of the crimping member of the present invention will be described by taking as an example a case where the crimping member is fixed to the end of the crimping rod body P1 and used (see FIGS. 1 to 3). First, in the crimping member of the present invention, by rotating the rotary knob 10, the top screw 9 screwed inside moves forward and backward. In this case, the head 2 of the end member 1 is urged by the compression coil spring S1 (first urging means) in a direction in which the head 2 is attracted to the crimping base 7, while the compression coil spring S2 is pressed.
It is urged by (second urging means) in a direction away from the crimp base 7. The compression coil spring S2 is connected to the end member 1
Is interposed between the head 2 and the top screw 9, and this top screw 9 is screwed into the rotary knob 10 as described above. Accordingly, the top screw 9 and the rotary knob 10 screwed thereto are always urged by the compression coil springs S1 and S2, which are urged in opposite directions, in a direction to be drawn toward the crimping base 7. . Therefore, even if the top screw 9 is moved in a direction away from the crimp base 7 by the rotation of the rotary knob 10 (the process of moving from the state of FIG. 2 to the state of FIG. 3), the rotary knob 10 itself is always drawn to the crimp base 7. Therefore, only the top screw 9 moves after all. On the other hand, when the top screw 9 moves in a direction away from the crimp base 7, the end member 1 attempts to move in a direction away from the crimp base 7 via the compression coil spring S2. Since the springs are urged in the direction of being drawn to the crimping base 7 by S1, if the spring forces of both compression coil springs are the same, they are compressed while balancing each other, and the end member 1 is moved by the amount of the compression. It moves in the direction away from the crimp base 7 and is urged (see FIG. 3). Therefore, in this state, a crimping rod S having a crimping member fixed to an end thereof.
When the end member 1 is passed between the wall surfaces having a slightly longer interval than its entire length, the end member 1 retreats in the direction of the crimping base 7 against the urging force, and abuts on the wall surface W by the urging force, thereby It is held between the wall surfaces of the rod S1 (see FIG. 4).
reference). The above-mentioned crimping force (determined by the amount of protrusion of the end member 1 from the crimping base 7) can be freely adjusted by rotating the rotary knob 10.

As is clear from the above description of the operation,
In the present invention, the rotary knob 10 always stays at a fixed position regardless of before or after holding the pressure-bonded bar between the wall surfaces. On the other hand, the relative distance between the inside of the rotary knob 10 and the top screw 9 which is screwed into and out of the inside of the rotary knob 10 is always constant irrespective of before and after holding between the wall surfaces of the crimping rod. Therefore, in order to make use of this characteristic, in this embodiment, the top screw
The rotary knob 10 is made of a transparent material (in this case, a transparent synthetic resin), and the top screw 9 is colored so as to be noticeable. Therefore, the user can know the crimping force of the crimping member by the progress of the top screw 9 which can be visually recognized through the rotary knob 10, and this operation is performed before and after the crimping rod is held between the wall surfaces. Can always be obtained.

In the above-described crimping member, the crimping base 7 is connected to a rod P
It is ready for use by fixing to the end of I. FIG.
FIG. 4 is a view showing a strut pole using the same. This strut pole inserts the second rod P2 into the cylindrical first rod P1 with the crimping member fixed to the end so as to be able to advance and retreat, and also fixes the both to a desired total length (here, the second rod P2).
(It is assumed that a threaded rod whose tip comes into contact with and separates from the outer periphery of the first rod body P1 inserted from the rod body P2) is held with a tensile force between the wall surfaces or between the ceiling and the floor. .

FIG. 8 is a view showing a tension shelf using the same. This strut shelf is provided with a means B (here, the second rod B2) for inserting the second rod P2 into the cylindrical first rod P1 with the crimping member fixed to the end so that the second rod P2 can be freely moved forward and backward. And a first rod P1 and a second rod P2 are prepared. The first rod P1 and the second rod P2 are prepared. The shelf S1 is bridged between the pair of first rods P1 and P1, and the shelf S2 is bridged between the pair of second rods P2 and P2. Is done.

[0021]

According to the crimping member of the present invention having the above-described structure, the end member itself is moved forward and backward by the rotation of the rotary knob independently rotating with respect to the end member to adjust the crimping force. This has the effect of eliminating the need for a mechanism for rotating a surface that comes into contact with the wall surface of the end member independently of the end member, as in the prior art for rotating.

The strength of the pressing force is proportional to the position of the coma screw which advances and retreats in the rotary knob, and the position of the coma screw does not change before or after holding the crimping rod between the wall surfaces. When the knob is made of a transparent material, the user can accurately know the crimping force of the crimping member by the progress of the top screw that can be visually recognized through the rotary knob.
