Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a flexible object whose main purpose is to press and fix furniture such as a closet and a bookshelf by pushing it between the upper surface and the ceiling of the furniture so as not to fall by an earthquake. Pressing fixture.

[0002]

2. Description of the Related Art If furniture such as a closet and a bookshelf falls due to an earthquake, not only the furniture is damaged but also the human body is dangerous. For this reason, a fall prevention tool for preventing furniture and the like from falling has been developed and is gradually becoming popular in general households. There is a structure in which the furniture and the wall surface or the crosspiece are fixed to each other via a metal member such as a hinge. However, opening the mounting screw holes of the fall prevention tool on the furniture and the wall will damage the furniture and the wall, and also prevent the tip from falling on places where detailed work is inappropriate, such as the top and back walls of the furniture. Since there is a hassle of having to screw the tool in, it is easy to shake the furniture when a large earthquake shakes enough to cause the furniture to fall if the wall surface is made of thin plywood or gypsum board. Since there is a risk that the screw will come off, there is a certain limit to its use.

As a fall prevention tool for eliminating these problems,
These are described in (1). Japanese Utility Model Publication 55-38930, (2). Japanese Utility Model Publication 56-51550, and (3). Japanese Utility Model Publication 55-139750.

In these fall prevention tools, pedestals are provided at both ends of which two pillars are connected so that their lengths can be freely adjusted and integrated, and both are provided between the upper surface of the furniture and the ceiling surface above it. In order to prepare for, the structure of pressing the upper surface of the furniture and the ceiling surface by the extension of the pillar, the one described in (1) and (2), the elastic repulsive force against compression between the pillar and the pedestal. The existing spring is interposed, and the furniture and the ceiling surface are pressed by the extension of the pillar and the spring force to prevent the furniture from toppling, and the one described in (3) discloses the extension of the pillar. The furniture and the ceiling surface are pressed to prevent the furniture from falling over.

The expansion and contraction structure of the support columns by these fall prevention tools is (1). The fall prevention tool described in Japanese Utility Model Laid-Open No. 55-38930 has two support columns (coupling members) each of which has one end side formed with a female screw member. It is connected with a connecting member so that it can be expanded and contracted, and the strut is structured to expand and contract by rotating the female screw member. (2). The fall prevention device described in Japanese Utility Model Laid-Open No. 56-51550 is an outer cylinder. The inner cylinder is inserted in the body in a stretchable state, pull out the inner cylinder to the required length from the outer cylinder, select an opening near this and insert a bolt there to set the extended position. (3). The fall prevention tool described in Japanese Utility Model Laid-Open No. 55-139750 has a part of a threaded support protruding into the rectangular tube and held at the upper end of the rectangular tube. Extend the threaded struts by rotating the adjustment grips It has a structure.

[0006]

However, like the fall prevention device described in Japanese Utility Model Laid-Open No. 55-38930,
When the structure is such that the two columns are connected by the female screw member, the expansion and contraction width of the column is determined by the length of the female screw member, and the expansion and contraction width is not so long as shown in FIG. 1 of the attached drawing of the publication. is assumed. As a result, there are many cases where the length corresponding to the distance between the furniture and the ceiling surface cannot be obtained.
Of course, it is not impossible to extend the expansion and contraction width of the column with this kind of structure, but for this purpose, it is necessary to lengthen the female screw member and correspondingly form a wide thread groove surface on the column. If this is done, the thread groove is exposed and the appearance of the fall prevention tool as a whole deteriorates. Especially, the part from the top of the furniture to the ceiling is often seen by people in the room, and if the fall prevention tool has the appearance of a construction tool,
It may damage the aesthetics of furniture and even the aesthetics of the room.

In addition, like the fall prevention tool described in Japanese Utility Model Laid-Open No. 56-51550, the structure is such that the inner cylindrical body fitted in the outer cylindrical body is advanced and retracted from the outer cylindrical body to expand and contract the entire column. The advantage of being able to obtain a long expansion and contraction width is that the locking position after expansion and contraction to the required length is determined by the bolt holes formed at predetermined intervals in the vertical direction of the inner cylinder. For this reason, in order to tension the fall prevention tool between the top surface and the ceiling surface of the furniture, extend both ends of the fall prevention tool until they contact the top surface and the ceiling surface of the furniture, and further, lower the inner cylinder body. While holding the, if the bolt is not locked at the position where the outer cylinder body on the upper side is pressed more strongly upward against the spring pressure,
If the pressing force on the furniture becomes loose and the furniture shakes due to an earthquake or the like, the overturn prevention device may fall down. However, it is difficult to position the bolt hole and insert the bolt there while pushing the outer cylinder body in the direction against the spring pressure because the installation position is near the ceiling. Work expected.

[0008] Further, as in Japanese Utility Model Laid-Open No. 55-139750, if the structure is such that a spring is not involved in the expansion and contraction of the pillar, the force for pressing the furniture and the ceiling cannot be adjusted, and the ceiling or It is expected to damage furniture.

It is to be noted that a coil spring having a space between the strips is installed in a non-rotatable state in the elongated outer cylinder body, and the elongated inner cylinder body is locked at one end thereof in the outer cylinder body. The pin is housed so as to be positioned between the lines of the coil spring, and the pin is moved along the line by rotating either the inner cylinder or the outer cylinder to expand and contract the inner cylinder. There are hanging hangers for clothes and clothesline clothes with adjustable length.It is easy to use this structure as it is to create a fall-prevention device that stretches the furniture and ceiling, but the pillar ( With a structure in which one of the cylinders is rotated to expand and contract, the pedestals attached to both ends of the column rotate together with this rotation, making it difficult to determine the orientation of the pedestal in a predetermined direction.

The present invention has been proposed in view of such circumstances, and a second cylinder is fitted into a first cylinder having a pedestal or a plug member at a base end thereof, and a tip of the second cylinder is gripped. Part 1
A coil spring that projects from the tip end opening of the cylinder and has a gap between the threads in the second cylinder is fixed, and the base end of this coil spring is fixed to the base end of the second cylinder. In addition, the coil spring is located inside the third cylinder, and the pin provided in the opening at the base end of the third cylinder is located at the tip of the pedestal or plug member so that the pin is located between the threads of the coil spring. By inserting the three cylinders from the base end side, it is possible to easily perform the expansion and contraction operation of the columns and the fine adjustment of expansion and contraction, and also to extend the expansion and contraction width of the furniture with good usability and excellent appearance. The purpose is to provide a fall prevention tool.

[0011]

SUMMARY OF THE INVENTION The furniture fall prevention tool of the present invention proposed to achieve the above object has a first cylinder having a pedestal at a base end thereof, and a second cylinder having one end thereof. Of the coil spring having a gap between the threads is non-rotatably housed in the second cylinder.
It is characterized in that the third cylindrical body having the pedestal at the tip is fitted into the second cylindrical body with the pin provided in the base end of the third cylindrical body positioned between the threads of the coil spring.

[0012]

In order to fix furniture using the pressing fixture according to the present invention, first, the entire length of the pressing fixture is extended to a length close to the length between the upper surface and the ceiling surface of the furniture. The length to be extended is sufficient for calculation, and by rotating the third cylinder in one rotation direction, the pin locked in the lower part of the third cylinder is separated from the stripe of the coil spring. If the third cylinder is moved upward along the gap, the third cylinder moves upward.

Even if the third cylinder is not rotated,
When the second tubular body is rotated in one direction while holding the grip portion of the second tubular body, the coil spring supported by the second tubular body in a state of being prevented from rotating also rotates together with the operating tubular body, With this rotation, the pin position of the telescopic cylinder moves upward, and the third cylinder moves upward. Of course, if the third tubular body and the second tubular body are rotated in the opposite direction to the above, the third tubular body moves in the shortening direction.

In this way, the main pressing fixture is preliminarily calculated to extend from the upper surface of the furniture to the vicinity of the ceiling surface, and is arranged as it is in the vicinity of both ends of the rear upper surface of the furniture. In this state, the grip portion of the second tubular body is provided. And rotate the second cylinder in one direction to
The tubular body is further extended upward, and the furniture and the ceiling surface are extended to such an extent that they are pressed under the spring pressure, and the rotation of the grip portion is locked at this position. In this state, since the expansion / contraction tubular body itself is restricted from moving in the vertical direction by the coil spring, the main pressing fixture can be fixed by pressing the furniture downward with the spring pressure applied. Since the third tubular body presses the ceiling surface via the upper pedestal and the coil spring is in a pressed state, the third tubular body does not easily rotate and the coil spring easily rotates. do not do. Therefore, the third tubular body does not naturally move downward. Of course, since the upper surface and the ceiling surface of the furniture are received by the pedestal which is formed widely, it is not damaged.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the specific construction of the pressing fixture according to the present invention will be described in detail according to the embodiments shown in the accompanying drawings.

FIG. 1 is a front view of a pressing fixture according to the present invention,
2 is a side view and FIG. 3 is a sectional view taken along line AA.

As shown in FIGS. 1 to 3, a pressing fixture A according to the present invention comprises a first cylindrical body 1 made of a long cylindrical cylindrical body made of metal or resin having strength, and a first cylindrical body 1. It is made of the same material as the cylindrical body 1 and has an outer diameter that is in sliding contact with the first cylindrical body 1.
The second tubular body 2 is formed to be slightly longer than the tubular body 1, and has a second tubular body 2 having a grip portion 7 formed on the outer peripheral surface at one end thereof and the same material as the above-mentioned tubular bodies. A third cylindrical body 3 having an outer diameter that allows sliding contact, and a coil spring 4 having an elongated shape that expands and contracts the third cylindrical body 3 and having a certain gap between the threads.
And two pedestals 5 and 6 are assembled together.

In the assembly structure, the first cylindrical body 1 is inserted so that one end 1a of the first cylindrical body 1 is not accidentally removed from the opening 5a formed on one surface of the pedestal 5. Second cylinder 2
One end where the grip portion 7 is not formed is non-rotatably closed by a plug 8 formed so as to fix one end of the coil spring 4, and the one end of the coil spring 4 cannot be rotated by the plug 8. In addition, the entire coil spring 4 is housed in the second tubular body 2 while being held so as not to come off.

In the second tubular body 2 thus containing the coil spring 4, the plug 8 is in contact with the upper surface of the pedestal 5, and the grip portion 7 above the second tubular body 2 is the first tubular body. It is located above the body 1, and the stopper 8 is screwed to the pedestal 5 in a rotatable state. 9 is the screw.

The third cylindrical body 3 has one end thereof inserted into an opening 6a formed on one surface of the pedestal 6 so as not to come off accidentally, and a pin 10 near the other end thereof. Is slightly obliquely penetrated and is locked so as not to project from the outer peripheral surface of the third cylindrical body 3.

In the third cylindrical body 3 thus constructed, one end side not provided with the pedestal 6 is inserted from the opening end of the second cylindrical body 2, and the pin 10 is inserted from the end portion of the coil spring 4. When the pin 10 is inserted in the gap between the strips and rotated in the direction along the strips of the coil spring 4, the second cylindrical body is in a state in which the pin 10 is deeply engaged with the coil spring 4 along the gap between the strips of the coil spring 4. The second cylindrical body 3 is moved in the depth direction of 2 and is accommodated in such a state that a part of the third cylindrical body 3 does not come out of the second cylindrical body 2.

When the third tubular body 3 is further rotated in the same direction, the third tubular body 3 is moved into the second tubular body 2 to the extent that the pedestal 6 on the upper side of the third tubular body 3 is located above the second tubular body 2. Can be accommodated.

Then, in order to extend the third cylindrical body 3, the third cylindrical body 3 may be rotated so that the pin position of the lower part thereof is moved upward along the space between the coil springs 4.

When the second tubular body 2 is rotated while holding the grip portion 7 of the second tubular body 2, the coil spring 4 is also rotated accordingly, and the pin position is pushed up along the gap to the third position. The cylinder 3 can be moved upward. When the second cylinder 2 is rotated to expand and contract the third cylinder, the third cylinder 3
Moves upward (or downward) without rotating.

The coil spring 4 is not only for moving the third cylinder 3 up and down, but also for the third cylinder 3.
The spring pressure is applied when is pressed downward. Therefore, it is possible to perform fine adjustment by applying spring pressure to the expansion and contraction of the third cylindrical body 3.

FIG. 4 is a diagram showing a method for pressing and fixing furniture B using the pressing fixture A according to the present invention. As shown in this figure, the pressing fixture A according to the present invention is furniture. It is preferable to dispose from the left and right rear of the upper surface of B toward the ceiling surface C. Further, since the furniture B falls down in the front direction against an earthquake, it is preferable that the pedestals 5 and 6 be oriented in the front-rear direction of the furniture. Since the pressing fixture A presses the upper surface of the furniture B and the ceiling C in a state where the spring pressure is applied in using the furniture B, the furniture B is firmly fixed, and the swing force within the range of expansion and contraction of the spring force. On the other hand, since it can be absorbed by this spring force, the furniture B and the ceiling C are not damaged even if the furniture B is slightly shaken by an earthquake. In addition, the furniture B and the ceiling C will not be damaged by turning the grip portion 7 too strongly.

The pressing fixture A of the present invention is not only for preventing the furniture B from being collapsed from an earthquake, but also for any member such as a member for temporarily fixing the partition plate (partition) of the room to the floor surface and the ceiling surface. It can be used for various purposes. Further, by attaching plug members instead of the pedestals provided at both ends thereof, it can be used also as a pole for hanging a hanger in the closet.

[0028]

According to the pressing fixture of the present invention having the above-mentioned structure, when it is used as a fixture for preventing the furniture from collapsing, the furniture is pressed by tension between the upper surface and the ceiling surface of the furniture. Since the structure is fixed, the furniture can be securely fixed without damaging the furniture, the ceiling surface, the wall surface, or the like.

Further, since the expanding and contracting structure is a structure in which the cylindrical body projects from the cylindrical body, the expansion and contraction width can be lengthened, and further, the expansion and contraction moves the cylindrical body along the ridges of the coil spring, Since the coil spring is also housed in the cylinder, the appearance can be made simple and good-looking.

In the expansion and contraction, the intermediate (second)
When the middle (second) tubular member is rotated by holding the grip on the upper portion of the tubular member, the third member expands and contracts without rotating, so the orientation of the pedestal changes during movement, and the furniture and the ceiling are pressed. The third cylinder does not rotate and shift its position during the operation.

Further, since the third cylinder is expanded and contracted by interposing the coil spring, the furniture and the ceiling can be pressed with a spring pressure. Therefore, the furniture and the ceiling will not be pressed and damaged. In addition, since the spring can absorb a slight shaking such as an earthquake, the furniture and the ceiling are not damaged.
