Conventional technology and its problems Conventionally, as a retractable pipe shelf installed between two members having an arbitrary interval, the shelf body is composed of a plurality of outer pipes, and the shelf body is movable in the longitudinal direction with respect to the shelf body. For example, a movable shelf made of an inner pipe and a rotary pressing body equipped with a screw mechanism on both sides of the shelf body or the ends of the movable shelf were developed in the 1980s.
This is shown in Publication No. 20840.

In the case of this type of pipe shelf, since the mounting surface is flat, objects such as dishes and pots placed on it tend to slip off, and it may be necessary to install a shelf to prevent them from falling. be. Furthermore, if the object to be placed is large, it may be necessary to expand the placement space in the width direction. However, conventional pipe shelves cannot meet these requirements, and there is the inconvenience of having to separately purchase pipe shelves of different sizes and shapes.

Purpose of the invention The present invention was made in view of the above-mentioned conventional problems, and its purpose is to provide a pipe shelf that can be used for different purposes, such as preventing objects placed on it from falling and expanding the storage space. There is a particular thing.

Structure of the Invention In order to achieve the above object, the present invention includes a first frame body and a second frame body that connect and hold both ends of a plurality of first outer pipes in a parallel state, and an inner side of the first outer pipes. and a third frame which connects and holds the other end of the first inner pipe in a side-by-side state, one end of which is inserted, and a retractable pipe shelf installed between two members having an arbitrary interval. , a second outer pipe and a second inner pipe that are slidably inserted into each other separately from the first outer pipe and the first inner pipe, and a first arm that holds both ends of the second outer pipe at one end. A second arm and a third arm having one end protruding to the outside of the second inner pipe constitute an auxiliary shelf, and the other end of the first to third arms and the first to third arms The third frame is formed with irregularly shaped cross-sectional parts that can be fitted and removed in the axial direction at regular angle intervals.

In other words, the auxiliary shelf consisting of the second outer pipe, the second inner pipe, and the first to third arms is attached to the pipe shelf body by adjusting the angle at regular intervals, so that it can be used as a shelf to prevent falling. It can be used for different purposes by expanding the mounting space.

Further, as shown in FIG. 6, a detent notch 1b is also formed at the right end of the outermost outer pipe of the first outer pipe 1, and the first outer pipe is formed on the left side of the second frame 4.
a fitting hole 4a into which the right end portion of the outer pipe 1 is fitted;
A protrusion 4b that engages with the notch 1b is formed on the inner surface of the fitting 4a, and an octagonal irregular cross section 4c is formed on the outside of the fitting hole 4a. The other end of the second arm 9 (lower part in FIG. 6) includes an insertion hole 9a that is inserted into the outside of the first outer pipe 1, and an octagonal irregular cross-section portion 9b.
is formed, and this irregular cross-section portion 9b is a second
It can be fitted into and removed from the irregular cross-section portion 4c of the frame body 4 in the axial direction at 45° intervals. Central hole 4 of second frame 4
The tip of the bolt 13 is inserted through the hole d, and the bolt 13 is prevented from coming off with respect to the second frame 4 by fixing a stopper 14 to the tip of the bolt 13.

The head 13a of the bolt 13 is embedded and fixed in the fourth frame 15, and an adjustment member 17 having a nut 16 embedded therein is screwed into the middle part of the bolt 13. Then, by manually turning the gripping part 17a having a knurl formed on the outer peripheral surface of the adjustment member 17, the protrusion length l of the bolt 13 is changed, and the distance between the fourth frame 15 and the second frame 4 is adjusted. It can be adjusted freely.

Note that a cushion material 18 such as rubber is attached to the outer surface of the third frame 5 and the outer surface of the fourth frame 15 so as not to damage the wall surface when pressed against the wall surface.

To install the pipe shelf with the above configuration on the opposite wall, first loosen the tightening screws 11 provided at the bottom of the first frame 3 so that the first inner pipe 2 can freely slide against the first outer pipe 1. Then, the total length L of the pipe shelf (see FIG. 1) is adjusted to be slightly shorter than the distance between the walls to be installed, and the first inner pipe 2 is fixed by tightening the tightening screw 11. Next, with the third frame 5 provided at the left end of the first inner pipe 2 in contact with one wall surface, the adjustment member 17 is rotated to increase the protruding length l of the bolt 13. Then, the fourth frame 15 is crimped onto the other wall surface to complete the installation.

In this way, the pipe shelf can be attached to the opposing wall surface without using any nails or wood screws, so the installation work is easy and the wall surface is not damaged. Further, by turning the adjusting member 17, the protruding length of the bolt 13 is increased and the fourth frame 15 is pressed against the wall surface, so that the stability in the attached state is extremely good.

By the way, if you place a spherical or cylindrical object on the top surface of the pipe shelf, there is a risk of it falling off.
In such a case, set the auxiliary shelf B in an upright position (as shown by the solid line in Figure 3) with respect to the pipe shelf main body A, and form a fall prevention shelf with the second outer pipe 6 and the second inner pipe 7. This makes it easy to prevent objects from falling. Additionally, when placing an object larger than the width of the frames 3, 4, and 5 on the top surface of the pipe shelf, there is a risk that the object may fall.
By compressing the second outer pipe 6 and the second inner pipe 7 in opposite directions, the irregular cross-section portions 8b of the arms 8, 9, 10,
9b and 10b are irregular cross-section parts 3 of frames 3, 4, and 5.
c, 4c, and 5c, and turn the auxiliary shelf B horizontally (indicated by the constant chain line in FIG. 3) and reinstall the irregular cross-section sections 8b, 9b, 10b, and 3c, 4c, and 5c.
By fitting them together, the mounting space of the pipe shelf main body A can be expanded in the width direction by the amount of the auxiliary shelf B. Furthermore, if you want to hang a cloth or towel on the pipe shelf, set the auxiliary shelf B downward (indicated by the two-dot chain line in Figure 3) and hang a cloth or towel on the second outer pipe 6 or the second inner pipe 7. If you hang a towel on it, it can also be used as a cloth rack without reducing the mounting space of the pipe shelf main body A. In addition, the irregular cross-section parts 8b, 9b, 10b and 3c, 4c, 5c
Since it has an octagonal shape, it can be set in the three positions of upright, horizontal and downward as mentioned above, as well as diagonally upward and downward positions.

Other Embodiments (1) In the above embodiment, the angle-adjustable auxiliary shelf B was provided only on one side of the pipe shelf main body A, but it may be provided on both sides. Further, the auxiliary shelf B may have two or more second outer pipes and second inner pipes,
Further, the second outer pipe and the second inner pipe may have different diameters from those of the first outer pipe and the first inner pipe, respectively.

(2) The pipe shelf of the present invention is not limited to one that is fixed to a wall surface as in the above embodiment, but for example, the bolts 13, adjustment member 17, and fourth frame 15 are eliminated, and the second frame 4 A mounting bracket may also be integrally provided on the third frame 5, and this mounting bracket may be fixed to the opposing wall surface with nails or screws. In this case, the first outer pipe 1 and the second inner pipe 2
The tightening screw 11 for fixing is unnecessary.

(3) The shape of the irregular cross section may be an octagon, as long as it can be positioned at certain angles, such as a square or a chrysanthemum pattern.

(4) In the embodiment, the other end of the arm was inserted and supported outside the first outer pipe and the first inner pipe, but
However, the present invention is not limited to this, and, for example, one end portion of the first to third frames may be extended in the width direction, and the extended portion may be provided with a modified cross-section portion to fit with the arm. In this case, the auxiliary shelf B can be separated from the pipe shelf main body A. On the other hand, in the case of the embodiment, since the arm is inserted into and supported by the first outer pipe and the first inner pipe, the auxiliary shelf B can be handled as one with the pipe shelf main body A without being separated, and even when used There is no risk of the auxiliary shelf B or falling off even if the irregular cross-section part becomes unfitted inside.

Effects of the Device As is clear from the above explanation, according to the present invention, an auxiliary shelf consisting of a second outer pipe, a second inner pipe, and three arms is provided with an irregular cross-section section relative to the pipe shelf main body. Since the angle of the auxiliary shelf can be adjusted, the angle of the auxiliary shelf can be easily adjusted to stand up or horizontal with respect to the pipe shelf main body.It can also be used as a shelf to prevent falls, expand the mounting space, and even be used as a cloth hanger. It can be used for different purposes.
