[0001]

[Industrial applications]

 The present invention relates to a foldable shelf on which a cleaning tool and various other items are placed for storage and storage.

[0002]

[Prior art]

 Among the shelves on which various kinds of articles are placed, as a foldable shelf, for example, one disclosed in Japanese Utility Model Publication No. 56-51794 is known. This shelf is provided with an elastic material in which the ends of two pipes are slidably inserted into each other, and the pipes of the pair of elastic materials are connected with a connecting material to provide a plurality of shelf materials that can expand and contract in the width direction. Configure. A plurality of shelves are attached by axially attaching the ends of the connecting and supporting members formed in an X shape by axially attaching the central portions of the pair of rods to the pipes of the elastic members of the shelf. The materials are connected together in a stacked state. Therefore, if the width of each shelf is widened, the bars forming the connection support become closer to each other in a horizontal state, and the shelves can be folded close to each other to reduce the bulkiness. When the width of each shelf is reduced and fixed in that state, the bars of the connecting support become farther from each other and become slightly upright, and the spacing between each shelf is increased to put them into use. Is.

[0003]

[Problems to be solved by the device]

 Since the conventional shelf can be folded to reduce its bulkiness, it is easy to store it when it is not used. Moreover, since the intervals between the shelves can be set almost at any time during use, it is possible to set the intervals between the shelves according to the application. However, since the intervals between the above-mentioned shelves are set according to the states of the bars of the connecting support member configured in an X shape, the intervals between the respective shelves are the same, and the intervals between the respective shelves are the same. It is difficult to make a difference.

Each of the shelves is configured to be expandable / contractible in the width direction, and is fixed so as not to be expandable / contractible during use. The width of the shelf is fixed by locking two pipes forming the elastic material. It is fixed so that it cannot slide. Therefore, the weight of the articles placed on the shelves may cause the width of the shelves to change widely and the spacing between the shelves to change. There is a problem that it is difficult to take out the article. In addition, there is a problem that the shelf material is slightly rattled based on the difference in diameter between the two pipes forming each elastic material.

The present invention solves the above-described problems, eliminates the restriction on the interval setting of each shelf, and eliminates the possibility that the interval of the shelf will change due to the weight of the placed articles. In addition, the purpose is to obtain a foldable shelf that prevents rattling and can be used stably.

[0006]

[Means for Solving the Problems]

 The folding shelf of the present invention comprises a pair of pipes or rods arranged in parallel at a distance from each other, and a pair of frame main bodies are erected parallel to each other and installed at one end in the horizontal direction of each frame main body. A bar-shaped support part is constructed in the up-and-down direction, a slide pipe is slidably attached to each support part, and two bar-shaped members are axially attached at the central part and can be folded into almost one bar-shaped member. An elastic connecting member that can be opened in an X shape is provided. One end of each rod-shaped member of this elastic connecting member is pivotally attached to the end of each support portion, and the other end of each rod-shaped member slides. A support member, which is pivotally attached to the pipe, one end of the shelf member is swingably mounted on one frame main body, and the other end of the shelf member is placed on the other frame main body is provided. Is characterized by.

The slide pipe attached to each of the support portions is formed of plastic, and a plurality of movable pieces circumferentially divided is provided at an end portion of the slide pipe. Then, an end portion of the slide pipe provided with the movable piece is movably connected with a screw, and a tightening pipe for tightening the movable piece is slidably provided on the support portion and erected on a pair of frame bodies. It is also possible to provide a shelf to be attached.

[0008]

In the folding shelf of the present invention, a pair of frame bodies are connected by an elastic connecting member that can be opened in an X-shape, and each rod-shaped member forming the elastic connecting member is rotated. Each frame body can be moved closer or further away. In this case, one end of the expansion and contraction connecting member is pivotally attached to each supporting portion, but the other end is pivotally attached to the slide pipe, so that each slide pipe slides along each supporting portion, The distance between the rod-shaped members of the expansion and contraction connecting member is changed to enable the movement of each frame main body. Therefore, by simply moving the pair of frame bodies closer to each other, the frame bodies can be folded closer to each other, and the frame bodies can be assembled in a used state only by moving the frame bodies away from each other. It is possible to perform each operation extremely easily and easily.

Since one end of each shelf is swingably attached to one frame main body in the vertical direction, when the frame main body is folded, each shelf is swung upward to be parallel to the frame main body. To When the frame body is assembled into a state of use, each shelf is swung downward and its free end is placed on the support provided on the other frame body. Therefore, the intervals between the shelves can be set almost arbitrarily, and the possibility that the shelves move downward due to the weight of the articles placed on the shelves can be eliminated.

When a movable piece is provided at the end of each slide pipe and a tightening pipe for the movable piece is provided, the movable pipe is tightened by moving the tightening pipe in the direction of the slide pipe with a screw. When the support pipe and the slide pipe are brought into pressure contact with each other, the support pipe and the slide pipe are integrated, and the slide pipe is fixed so as not to slide. When the tightening pipe is rotated and moved in the opposite direction, the slide pipe can be slid. Therefore, if the tightening pipes are tightened when the shelves are assembled for use, the relatively high rattling of each frame body is eliminated, and the stability of the entire shelves is increased. Then, when the tightening pipe is tightened when the frame body is folded, the free movement of each frame body is lost and it is easy to carry and handle. Further, depending on the structure of the shelf material, one end or both ends thereof can be attached / detached so that the pair of frame bodies can be assembled and folded.

【Example】

 An embodiment of the folding shelf of the present invention will be described with reference to the drawings. In the figure, 1a and 1b are frame bodies, which are formed by bending an iron pipe into an inverted concave shape, and each of the vertically facing parts constitutes four support parts 2a and 2b. ing. Reference numeral 3 is a fixed pipe fixed to the upper end of each support portion 2b, 2b by inserting each support portion 2b, 2b of the frame body 1a, 1b, and a bracket 4 is provided on the side surface thereof. Reference numeral 5 is a lock pin that fixes each fixed pipe 3 to the supporting portions 2b, 2b.

Reference numeral 6 denotes a slide pipe which is inserted through the support portions 2b and 2b and is slidably attached to the support portions 2b and 2b, and a bracket 7 is projectingly provided on a side surface of the slide pipe. Reference numeral 8 denotes a plurality of dividing grooves formed in the end portion of the slide pipe 6 at intervals in the circumferential direction, 9 denotes movable pieces formed between the respective dividing grooves 8, and each movable piece 9 is a movable piece of the slide pipe 8. It is possible to bend slightly in the radial direction by elastic deformation and press the peripheral surface of the support portion 2b. Reference numeral 10 is a thread formed on the peripheral surface of each slide pipe 6 provided with the movable piece 9.

Reference numeral 11 denotes a tightening pipe slidably attached to each of the supporting portions 2b and 2b, which contacts a connecting portion 12a into which the thread 10 side of the slide pipe 6 is inserted and an outer surface of the movable piece 9. And a pressure taper portion 12b that presses each movable piece 9 against the peripheral surfaces of the supporting portions 2b, 2b and presses the movable thread 9 to the inner peripheral surface of the coupling portion 12a. 13 are formed. The end of the slide pipe 6 is inserted into the connecting portion 12a side of the tightening pipe 11, and the screw thread 10 and the thread groove 13 are engaged with each other to connect the tightening pipe 11 to the slide pipe 6. Although the slide pipe 6 and the tightening pipe 11 are shown separately in FIG. 5, when the tightening pipe 11 is loosened, the slide pipe 6 and the tightening pipe 11 may be connected to each other. .

Reference numeral 14 denotes a stretchable connecting member, which is a pair of rod-shaped members 15a and 15b made of strip-shaped metal plates. It is configured so that it can be closed by stacking on it and opened in an X shape. One end of each of the rod-shaped members 15a and 15b constituting the elastic connecting member 14 is axially attached to the bracket 4 of each fixed pipe 3 and each other end of the rod-shaped members 15a and 15b is attached to the bracket 7 of each slide pipe 6. The frame main bodies 1a and 1b are connected to each other in parallel to each other via a fixed pipe 3 and a slide pipe 6 by a stretchable connecting member 10 via a fixed pipe 3 and a slide pipe 6.

Reference numeral 17 denotes a plurality of support rods installed on the support portions 2a and 2b of the frame body 1a at intervals in the lengthwise direction, and the end portions of the shelves 18 are rotatably attached to the respective support rods 17. It is installed. Then, the bar-shaped members 15a, 15b of the expansion and contraction connecting member 14 are brought close to each other in the vertical direction to maximize the distance between the frame main bodies 1a, 1b, and at the distance between the frame main bodies 1a, 1b. Corresponds to the length. 19 is a support rod installed on the support portions 2a, 2b of the frame body 1b at intervals along the length thereof so as to support the respective free ends of the shelves 18 in the horizontal direction. The supporting rods 19 are provided in the same number as the supporting rods 17. Reference numeral 20 is a caster attached to each lower end of the supporting portions 2a and 2b.

When the folding shelf is to be used, the tightening of each tightening pipe 11 is loosened, the movable piece 9 of the slide pipe 6 is released, and each slide pipe 6 can be slid with respect to the supporting portions 2b, 2b. To In this state, as shown by the solid line in FIG. 1, the frame bodies 1a and 1b are moved in the directions away from each other. Then, the slide pipes 6 slide along the supporting portions 2b, 2b of the frame bodies 1a, 1b in the direction of the fixed pipe 3, and the rod-shaped members 15a, 15b of the expansion and contraction connecting member 14 become close to each other in the vertical direction. Then, the frame bodies 1a and 1b move in a direction away from each other. With the gap between the frame main bodies 1a, 1b being the largest, each shelf 18 whose end is attached to the support rod 17 is rotated downward, and the other end is placed and supported on the support rod 19. Further, the tightening pipe 11 is tightened and the pressure taper portion 12b presses the movable piece 9 against the supporting portion 2b to fix the slide pipe 6 to the supporting portion 2b in a non-sliding manner.

The assembled folding shelf is used for storing the cleaning tool or other articles by placing a cleaning tool or other article on each shelf member 18 from each supporting portion 1a side of the frame bodies 1a, 1b. Then, in this folding shelf, as described above, each tightening pipe 11 is tightened, the movable piece 9 of the slide pipe 6 is pressed against the supporting portion 1b, and each slide pipe 6 cannot slide on the supporting portion 1b. It is fixed to. Therefore, there is no possibility that the positional relationship between the rod-shaped members 15a and 15b forming the expansion and contraction connecting member 14 will change, the interval between the frame main bodies 1a and 1b will change, and the frame main bodies 1a and 1b will not rattle. Stable and well-folded shelves can be used.

Further, casters 20 are attached to the respective support portions 2a, 2b of the frame bodies 1a, 1b to facilitate the movement of the folding shelf, but as described above, the frame bodies 1a, 1b are expanded and contracted. Since it is possible to immovably fix it with the connecting member 14, it is possible to move the folding shelf by the casters 20 in a stable manner. Since the tightening pipe 11 presses the movable piece 9 of the slide pipe 6 onto substantially the entire circumferential surface of the support portion 2b, the slide pipe 6 can be firmly fixed to the support portion 2b. The tightening pipe 11 when tightened is fixed to the slide pipe 6 by engaging the screw thread 10 and the screw groove 13, so that the tightening pipe 11 rotates unnecessarily to release the movable piece 9. Without fear, it is easy to maintain the state where the slide pipe 6 is stably fixed to the support portion 2b.

When the folding shelves are not used, when they are folded, the fastening pipes 11 are loosened, the movable pieces 9 of the slide pipes 6 are released, and the support portions 2b of the frame bodies 1a, 1b are released. The slide pipe 6 can be slid with respect to. Then, as shown by the chain line in FIG. 1, each of the shelves 18 is rotated upward with the support rod 17 as a support shaft to move the frame bodies 1a and 1b in a direction toward each other. Then, each slide pipe 6 slides toward the caster 20 side with respect to the supporting portions 2b, 2b, and as shown by the chain line in FIG. 1, the rod-shaped members 15a, 15b of the expansion joint 14 are horizontally close to each other. Then, the frame bodies 1a and 1b can be folded close to each other to reduce the bulk. In this way, by tightening the tightening pipe 11 in the folded state and fixing the slide pipe 6 to the support portion 2b, it is possible to prevent the frame bodies 1a and 1b from moving in the directions away from each other, and thus the folded body can be prevented. It is possible to carry the folding and folding shelves more smoothly.

Since the shelf members 18 are supported by the support rods 17 and the support rods 19 provided on the frame bodies 1a and 1b, there are few restrictions on the intervals between the shelf members 18 and the shelf members 18 on which various articles are placed. It is possible to mount each article in a stable manner without fear of changing the interval.

As in the previous embodiment, if the end of the shelf 18 is rotatably attached to the support bar 17, the folding shelf can be assembled or folded into a usable state only by rotating the shelf 18. It is possible to collapse. In addition, when packaging for transportation or the like, it is possible to position the shelf material 18 between the frame bodies 1a and 1b for packaging, which simplifies the packaging and makes it possible to handle only the shelf material 18. It is unnecessary and the shelf material 18 is easy to handle. However, it is also possible to attach the shelf member 18 to the support rod 17 and the support rod 19 in a separable manner without attaching the shelf member 18 to the support rod 17. The attachment means of can be arbitrary.

In addition, the movable piece 9 is formed at the end of the slide pipe 6, and the tightening pipe 11 is provided, so that the slide pipe 6 is fixed to the frame main bodies 1a and 1b by tightening the tightening pipe 11. For example, it is possible to fix the frame bodies 1a and 1b in use to improve stability. However, since the shelves are often used by placing them in a fixed position, there is no problem in using them even if the slide pipe 6 is not fixed to the supporting portions 2b, 2b of the frame bodies 1a, 1b. It is also possible not to provide the tightening pipe 11.
