開昭60−20840号公報に示されている。Conventional technology and its problems Conventionally, as a retractable shelf that is installed in a stretched state between wall surfaces having an arbitrary interval, a shelf main body consisting of a plurality of outer pipes and a shelf extending longitudinally from the shelf main body are used. For example, Japanese Utility Model Application Laid-open No. 60-20840 discloses a movable shelf made of an inner pipe that can be moved in one direction and a rotary pressing body equipped with a screw mechanism on both sides of the shelf body or the ends of the movable shelf. ing.

い。 In the case of the above shelf, by expanding and contracting the shelf body and the movable shelf, it is possible to install it between the walls whose maximum length corresponds to the sum of the lengths of both pipes, but in reality, the shelf body and the movable shelf If the pipes are stretched to a certain extent, they will bend at the joint, so it is necessary to overlap the pipes over a fairly long dimension, which results in wasteful lengths of pipes that become longer than the space that can be installed. Ta. In particular, since high-strength steel pipes must be used for the shelf body and movable shelves, which are subject to a particularly large compressive load, the weight increase is significant.

部品点数の増加を来す欠点があつた。 Furthermore, the above-mentioned shelf is equipped with a locking device for fixing the shelf body and the movable shelf, but this locking device is fixed to the frame via a cam mechanism by rotating the support shaft. This makes the structure complicated and expensive, and since the cam mechanism's claws only engage the inside of the pipe, it cannot handle large thrusting tensions. Furthermore, a rotary pressing body equipped with a screw mechanism at the end of the support shaft is provided to support the wall, but since the bolt is screwed into a nut fixed to the support shaft, The tension is concentrated on this nut, and if the bolt is tightened even slightly at an angle, the threaded surface is likely to be damaged. In addition, it is necessary to provide a pressing body between the rotating pressing body and the wall surface to absorb relative rotation, and the sliding resistance between the rotating pressing body and the pressing body makes it difficult to turn the rotating pressing body, and the parts There was a drawback that caused the score to increase.

になつている。 As shown in FIGS. 4 and 5, the first frame 2 is formed with a recess 2a having a semicircular pipe sliding surface 2b, and a tightening screw 5 is inserted from the outer surface to the recess 2a. An insertion hole 2c is formed. A spacer 10 having a semicircular pipe sliding surface 10a corresponding to the pipe sliding surface 2b is fitted into the recess 2a, and a screw insertion hole 10b is provided in the center of the spacer 10. A square nut 11, which is screwed into the fixing screw 5, is embedded and fixed in the opening of the screw insertion hole 10b. Then, by turning the fixing screw 5 by hand, the fixing screw 5 is
is screwed into the square nut 11, and the tip 5a bites into the pipe 4 while burring, so that the pipe 4 can be fixed to the first frame 2 at an arbitrary position.

きる。 Near both sides of the second frame body 3, as shown in FIG. A portion 3b is provided to protrude, and a cylindrical guide portion 3c is provided to protrude from the inside. After the tip of the screw shaft 7 is inserted into the insertion hole 3a, it is prevented from coming off by fixing a stopper 13 to the tip, and the guide portion 3c guides the stopper 13 to prevent the screw shaft 7 from tilting. It is regulated. The head 7a of the screw shaft 7 is inserted into a hexagonal hole 8a formed in the fourth frame 8, and is fixed to the fourth frame 8 by a sleeve 14 that is press-fitted or adhesively fixed into the hexagonal hole 8a. . A cushion material 15 is also attached to the outer surface of the fourth frame 8. A metal nut 16 that engages with the screw shaft 7 is embedded and fixed inside the butterfly-shaped adjustment member 9, and by turning the adjustment member 9 by hand, the protrusion length l of the screw shaft 7 can be changed, and the second Frame body 3
The distance between the fourth frame body 8 and the fourth frame body 8 can be freely adjusted.

面に圧着させ、設置を完了する。 To install the shelf on the opposite wall, first loosen the fixing screws 5 so that the pipe 4 can slide freely against the first frame 2, and then adjust the total length L of the shelf (see Figure 1) to the wall where it is to be installed. Adjust it slightly shorter than the interval and tighten the fixing screw 5.
The pipe 4 is fixed by tightening.
Next, the adjusting member 9 is rotated with the third frame 6 in contact with one wall surface, and the protruding length l of the screw shaft 7 is adjusted.
By increasing the amount, the fourth frame 8 is pressed against the other wall surface, and the installation is completed.

れ強度や曲げ強度も劣らず、しかも小物や瓶類を
載置しても落下したり転倒するおそれがない。 The shelf having the above structure has the following effects. First of all, since the shelf main body 1 is formed into a hollow plate shape, it is lighter and cheaper than the conventional one using multiple pipe materials, and it has the same torsional strength and bending strength. Moreover, even if small items or bottles are placed on it, there is no risk of it falling or tipping over.

い。 Secondly, since the tip of the screw shaft 7 is only inserted into the second frame 3 and prevented from coming out, the tension force acts on the contact surface between the adjustment member 9 and the second frame 3, causing the sliding The adjustment member 9 can be easily rotated with little dynamic resistance, and even if the screw shaft 7 is tilted with respect to the second frame 3, the screw surface will not be damaged.

第３に、第４枠体８は２本のネジ軸７を連結保

ジ軸７が追随回転せず取付作業が容易である。 Thirdly, since the fourth frame 8 connects and holds the two screw shafts 7, when the adjustment member 9 is rotated, the screw shafts 7 do not follow and the installation work is easy.

第４に、棚本体１とパイプ４とを固定ネジ５に
よつて固定するようになつているので、固定強度

よび構造を簡素化できる。 Fourthly, since the shelf body 1 and the pipe 4 are fixed by the fixing screws 5, the fixing strength can be adjusted by the tightening force of the screws 5, and the number of parts and structure can be simplified.

ングしつつ食い込ませる方が好ましい。 Note that the fixing screw 5 is not limited to one that burrs and bites into the pipe 4 as in the above embodiment, and it is also possible to simply press the tip of the fixing screw 5 to the outer peripheral surface of the pipe 4, but when heavy objects are to be placed. Since the fixing screw 5 must receive a strong thrusting tension, it is not enough for the fixing screw 5 to simply press against the pipe 4, and it is preferable to press the fixing screw 5 into the pipe 4 while burring it as in the above embodiment. .

きる。Effects of the invention As is clear from the above explanation, according to the invention, the shelf body is made into a hollow plate, and the fixing structure between the shelf body and the pipe and the tension structure using screw shafts are simplified, so the number of parts is reduced. It is possible to obtain a shelf that is small in size, lightweight, has high tensile strength, and is inexpensive.
