Description

  The present invention belongs to a three-sided stretch structure that can be fixed using three surfaces of an upper surface such as a ceiling and a lower surface such as a floor and one wall surface orthogonal to these two surfaces, and is provided at each corner of a room, a closet, a kitchen, etc. It can be suitably used.

A strut is generally a stretchable bar or tube, combined with a coil spring that applies force in the direction of extension or a stopper that has a predetermined length, and is stretched on two opposing surfaces such as the ceiling, floor, and left and right walls in the closet. This is what is fixed. And when fixing between a ceiling and a floor, a shelf etc. are attached in the middle (FIG. 1 of patent document 1), and when fixing to a right-and-left wall, an accessory can be suspended. If you want to fix the bars in the horizontal direction in an environment where there are no vertical walls on the left and right, first fix the two tension bars by pulling them on the top and bottom surfaces, and then attach the third tension bar to the two tension bars. A structure for fixing a bar horizontally has been proposed (Patent Document 2).

However, when a single stick is fixed in the vertical direction as in Patent Document 1 and a shelf or the like is attached thereto, the shelf is only fixed in a cantilever manner, so that the shelf itself has a small area. Limited to lightweight ones. In addition, when the third rod is fixed horizontally to the two vertical rods as in Patent Document 2, the flat surfaces for fixing the two vertical rods are required at four locations above and below. Become. Therefore, it cannot be installed if there is no flat surface, such as a foreign object or recess in the place to be fixed, and if it is fixed to a narrow corner, the use space can be further narrowed by a corner-side tension bar. Impairs comfort.
Therefore, an object of the present invention is to provide a three-surface strut structure that can effectively use a blind spot space such as a corner regardless of the presence or absence of a flat surface.

In order to solve the problem, the three-sided strut structure of the present invention is
Stretchable rods that can be stretched and fixed to each other surface facing both end surfaces,
One end is slidable along the longitudinal direction of the both ends of the rod, and has a pressure contact portion that can be brought into pressure contact with the third surface opposite to the other end. It is characterized by comprising a stretchable one-end stretchable bar that can be fixed between the bar and the third surface. The opposite surfaces of the other objects are, for example, a ceiling surface and a floor surface, or left and right or front and rear wall surfaces. The third surface is, for example, one of the left and right wall surfaces when each other surface is a ceiling surface and a floor surface, and the ceiling surface or floor surface when each other surface is a left or right or front and back wall surface. .
According to this stretch structure, first, the both-end stretch rod can be stretched and fixed to any other surface of the other surfaces facing both end surfaces if there is a flat surface. The both end tension rods usually comprise an outer cylinder, an inner cylinder fitted to the outer cylinder, and tension means for stretching both the cylinders in the extending direction. The same applies to the one-end tension bar. As the tension means, a known technique such as a coil spring built in both cylinders or a set screw that penetrates the outer cylinder with a screw motion in the radial direction and press-contacts the inner cylinder can be applied.

Next, the one-end tension bar can be slid along the longitudinal direction of the both-end tension bars and the height can be freely changed. And it is fixed by the drag received from both end tension bars and the third surface by stretching at a desired position. Therefore, there is no need to have both end tension bars on the pressure contact portion side of the one end tension rod, and the upper and lower surfaces of the pressure contact portion side need not be flat. The pressure contact portion may be formed of an elastic material such as a sucker or a rubber plate.
In the tension structure of the present invention, it is preferable that the one end of the one-end tension rod has a dispersion portion that disperses the drag received from the third surface in the longitudinal direction of the both-end tension rod. This is because, even if the both-end struts are made thinner, the straightness of the both-end struts is maintained, and the one-end struts are securely fixed.

  Since there is no need to have both end tension bars on the pressure contact portion side, that is, the front end side of the one end tension bar, and the upper and lower surfaces of the distal end side need not be flat, a narrow corner can be used effectively. In addition, since the one-end tension bar is fixed on both sides of the both-end tension bars and the wall surface, a large-area shelf can be attached. Furthermore, the width | variety of a single-end tension rod can be freely set within the expansion-contraction range by moving the fixed position of a both-end tension rod.

Embodiment 1
A first embodiment of the strut structure of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a tension structure according to the embodiment.
This structure is composed of one end-stretching bar 1, one end-stretching bar 2, and a shelf 3. The both-ends-stretching rod 1 includes an outer cylinder 1a having a large diameter and an inner cylinder 1b having a smaller diameter than the outer cylinder 1a. Rubber discs 1c and 1d are attached to the respective ends of the outer cylinder 1a and the inner cylinder 1b, and the outer cylinder 1a and the inner cylinder 1b are fitted to each other at the ends to which the rubber discs 1c and 1d are not attached. The A coil spring (not shown) is inserted into the outer cylinder 1a, one end of which is fixed to the end of the outer cylinder 1a on the rubber disc 1c side, and the other end is inserted into the inner cylinder 1b. A pin protrudes in the radial direction on the inner peripheral surface of the inner cylinder 1b so as to be related to the coil spring. As the inner cylinder 1b rotates, the pin is guided by the coil spring and displaced spirally, and the inner cylinder 1b. Is moved forward and backward in the axial direction. Therefore, the length of the both ends tension rod 1 is determined by the position of the pin with respect to the coil spring.

Similarly, the one-end stretch rod 2 includes a large-diameter outer cylinder 2a and a small-diameter inner cylinder 2b. At the end of the outer cylinder 2a on both ends of the tension rod 1 side, a connecting tool 8 to the both ends of the tension rod 1 is attached. The connector 8 has a T-shape projecting in both directions orthogonal to the inner cylinder 2b, and a through hole having an inner diameter slightly larger than the outer diameter of the outer cylinder 2a is formed in the orthogonal direction. When the outer cylinder 2a is fitted into the through hole, the one-end stretching rod 2 is fixed to be slidable with respect to the outer cylinder 2a. A rubber disc 2d is attached to the tip of the inner cylinder 2b.
The shelf 3 is fixed to the outer cylinder 2a.
When this strut structure is used at the corner of the room, the outer cylinder 1a of the both ends strut rod 1 is turned down, the inner cylinder 1b is turned up, the inner cylinder 1b is rotated to extend the entire length, and the rubber discs 1c, 1d are Each is fixed to the lower surface of the floor and the upper surface of the ceiling. Next, the one-end tension bar 2 is moved together with the shelf 3 to a desired height, the inner cylinder 2b is rotated to extend the entire length, and the rubber disk 2d is pressed against the wall surface, whereby the one-end tension bar 2 is fixed. There is no problem even if the upper and lower surfaces near the wall are not flat or foreign objects are present. In addition, since the one-end stretch rod 2 is supported at two points on both ends, a large amount of articles can be placed with the shelf 3 having a large area.

  In addition, if the both ends tension rod 1 is made thin for weight reduction or the like, the bending resistance of the both ends tension rod 1 becomes smaller than the force received from the one end tension rod 2, and the one end tension rod 2 cannot be stretched too strongly. . In such a case, as shown in FIG. 2, it is preferable that the force received from the one-end strut rod 2 is distributed in the longitudinal direction of the both-end strut rod 1 by branching the base 2 f of the one-end strut rod 2.
