Description

DETAILED DESCRIPTION OF THE INVENTION The present invention can be applied to objects that can be used, for example, to hold a shelf at a desired height by attaching it to a vertical support, or to hold a window at a desired height by attaching it to an elevating window. The present invention relates to a universal locking device for locking an object at any position on a support member against gravitational or other forces.

Conventionally, this type of locking device is often used, for example, in the case of a shelf, holes are raised intermittently at a certain pitch on the support, and a special-feed base is hung on the holes to place the shelf. The height can be adjusted by directly attaching the board, but since the holes are intermittent, it is not possible to select the desired height, and if you want to change the height from time to time, you cannot operate it. It was troublesome.

In addition, in the case of an elevating window, there are pins that go in and out horizontally on both sides of the window, and the pins are inserted into holes made in the window frame at the desired height to adjust the window to the desired height. However, since the holes are intermittent, it is not possible to select a desired height, and the holes also have the disadvantage of getting clogged with dirt. In order to set the height continuously and arbitrarily, for example, for a shelf board, as shown in FIG. There is something like that.

The structure of this locking tool 2 is as shown in FIGS. 2a and 2b, the flange 4 of the support column 1 is sandwiched between a shoe 5 and a wedge body 6, and the shoe 5 is attached to a cover unit 7, and the wedge body 6 and flange 4 are held together. It is provided with a support rod 8 as a pinching and external force support part and a push rod 9 as a release operation part, and a spring 15 constantly pushes the wedge body 6 to prevent it from loosening. Supports loads such as shelf boards. When hung on the upper end of the rod 8, it becomes automatically vertical due to the wedge action of the wedge body 6, and the pillar 1 is relatively firmly attached.
is retained. However, when removing it, the push rod 9 is pushed up from below, but a considerable compressive force remains between the wedge body 6 and the flange 4. In this state, wedge body 8
It is extremely difficult to remove the support while sliding it relative to the flange 4, and the surface of the support is also likely to be damaged.
In addition, in order to make extraction relatively easy,
As shown in Fig. b, there is a wedge body 8 with a ball 10 housed in it, and when it is difficult to pull it out, the rolling action of the ball 10 makes the work easier, but the local compression from the ball 10 causes the support 1 to collapse. It had drawbacks such as the tendency to cause deep scratches on the surface.

The present invention has a pair of shoes configured to be locked to a support member by gripping force or expansion force, and at least one of the shoes has an inclined surface on the back side of one side of the shoe, and a wedge is formed on the inclined surface. By making the body slide, the wedge body and the supporting material surface do not come into direct contact, and relative sliding with the support surface is not required when loosening the wedge body, eliminating the above-mentioned drawbacks of the conventional one. It is an object of the present invention to provide a universal locking tool that can be installed and removed extremely easily with a small amount of force, and that can lock an object in any position without damaging the supporting material.

The present invention has at least a pair of shoes capable of applying a pair of opposing pressing forces to a part of the support material through the shoe surfaces to lock the universal locking device itself to the support village, a wedge body which is movably held along the back surface of the shoe surface of one of the shoes and which can increase or decrease the distance between the shoe surfaces of the pair of shoes; This is a universal locking device characterized by being provided with an external force support portion and having a release operation portion provided on the thinner side.

To explain the present invention with reference to the drawings, FIGS. 4 and 5 show that the branch 1 serving as a supporting member has a T-shaped cross section, the wedge 6 is tapered on both sides, and the wedge body 6 and A shoe 11 is provided between the flange 4 and the flange 4.

One side of the shoe 11 is in contact with the flange 4 as a shoe surface,
The back surface is an inclined surface and is in contact with the wedge body 8. In this state, if a load is applied, such as by placing a shelf board on the support rod 8, the wedge body 8 will be firmly attached to the support column 1 by its automatic connecting action.

To remove it, put your fingers on the upper end of the cover unit 7 and the lower end of the push rod 9 and lift the wedge body 6 upward. In this case, since the wedge body 6 is tapered on both sides, extraction is extremely easy.
Furthermore, no relative sliding occurs with respect to the surface of the support column 1, and the surface of the support column 1 is not damaged. 6 and 7 show another embodiment, in which a ball 10 is housed in a wedge body 8. FIG.

The thickness of the wedge body 6 near the housing part of the pole 10 is slightly thinner than the diameter of the ball 10, so the ball 10 hits the shoe 11 and the slope of the cover body 7 before the wedge body 8 hits the shoe 11 and the slope of the cover body 7, so there is no ball 10. If the taper accuracy is poor, problems such as uneven contact may occur in the case of a metal wedge, but this problem can be eliminated, and contact can be made at a predetermined position to perform a reliable wedging action. The contact portion of the ball 10 is the 10th
As shown in FIG. 11, a ball seat 12 is provided by partially embedding a hard material such as high carbon steel. Each part is often made of aluminum alloy for weight reduction and currency resistance, which improves dust resistance and deformation resistance. Figure 8,
FIG. 9 shows the wedge body 6. The thickness of the wedge body 6 is such that when the ball 10 hits the slope of the shoe 11 and the cover body 7, there is a small gap between the wedge body 6 and the slope (for example, 0.1
~0.2 Yanagi) If you choose darkly, the ball 10 due to overload.
Even if the ball sinks into the slope, the wedge body 6 hits the ball 10.
This can prevent the material from sinking even deeper.

FIGS. 12, 13, and 14 show another embodiment in which the branch office 1 has a rectangular cross section. It has a structure in which the green end flange 4 is gripped by the shoes 5 and 11. A protrusion 13 is provided on the shoe surface of the shoe 11 and enters the hole 14 of the shoe 5 to prevent the shoe 11 from slipping. The dimensions are smaller than in the case of a column with a T-shaped cross section. Figures 15 and 16 are shoe 11, Figure 17, and I8.
The figure shows show 5. 19 to 22 show another embodiment in which the cover 16 of the support rod 8 and the cover 17 of the push rod 9 cover the cover unit 7, and the cover unit 7 is provided with a finger rest 18.

When loosening, the lower end of the cover 17 serves as a finger rest and the wedge body 6 can be easily raised and loosened using the finger rest 18, and can be moved to any desired position and set. FIG. 23 shows another embodiment in which the covers 16 and 17 are integrated, and only the finger rest 18 is exposed from the integrated cover, which has a good appearance and is easy to operate.

FIGS. 24 and 26 show another embodiment, in which each part is manufactured by pressing.

It can be manufactured at a lower cost than when the protrusions 13 are formed integrally. The spring 15 is inserted between the cover 17 of the push rod 9 and the cover unit 7, and since the space is relatively large, there is no flexibility in design. FIGS. 30 and 31 show a case where there are two springs 15, and the lengthwise dimension can be shortened. FIGS. 32, 33, and 34 show another embodiment in which locking is performed by the expanding force of a pair of shoes 5, 11 from the inner surfaces of opposing sides of a column 1 having a 0-shaped cross section.

It is a stand on which shelves and the like are placed, and is subjected to moments by rollers 21 and 22.

35 and 36 show another embodiment in which the rollers 23 are provided in two stages.

FIG. 37 shows an embodiment of the 38th leg trap, in which an expansion force is applied between the end green flange of the 0-shaped support and the bottom surface.

FIGS. 39 and 40 show another embodiment, in which a part of the stand 20 enters the support column and takes a moment. FIGS. 41, 42, and 42a show another embodiment in which the entire structure is placed inside the support column 1. FIG. Shoes 5 and 11 do not directly contact support 1,
The covers 24 and 25 are pulled together by a spring 26.
FIGS. 43 and 44 show another embodiment, which is an expanded type. 45 and 46 show another embodiment of an expanded type, both of which are within the cross section of the support column 1. FIG.

In particular, the one shown in FIG. 45 does not have an integrated cover, making it very small and compact. There are pins 2 at both ends of shoes 5 and 11.
7 and are connected by a latch 28. The thicker side of the wedge body 6 is not tapered but has a parallel surface. This allows both shoes 5 and 11 to be narrowed. FIGS. 47 and 48 show examples in which it is used for a shelf board. By attaching the flexible locking device 2 to the column 1 at an arbitrary position, the special feed 29 can be easily attached to the desired height of the shelf board 3.
It is also easy to adjust.

Details are shown in FIGS. 49 and 50. Figure 51, 5th
In Fig. 2, a primary shelf board 3 is supported by four freely locking brackets 2. Figures 53 to 55 show examples of use in elevating windows.

4, the wedge body 6 is pushed up relatively, and the restraint of the shoes 5 and 11 is loosened, allowing the window 30' to move up and down freely.

When the finger reaches a predetermined position and is released, the wedge body 6 is pushed in by the force of the spring 15, and the shoes 5 and 11 are attached to the flange 4 of the support 1.
Furthermore, the weight of the window 30 is transmitted to the support rod 8 and is firmly held by the automatic squeezing action. 56 to 58 show another embodiment in which the guide rail of the window 30 and the support 1 of the universal locking device 2 are common.

Fig. 59 shows another embodiment, in which the push rod 9 is accidentally removed after setting.
The clamp body 35 is configured to push the shoe 11 through the ball 10 so that it will not loosen even if something hits it, and the clamp body 35 is attached to the cover body 7 by an eccentric shaft 36.

After normal setting, rotate the eccentric pith 36 and clamp the clamp body 3.
5 pushes the ball 10 and indirectly pushes the shoe 11 to firmly clamp it. The direction of the eccentric shaft 36 is perpendicular to both the sliding direction of the wedge body 6 and the direction in which the clamp body 35 and the shoe 11 are separated from each other. 60 and 61 show another embodiment in which the eccentric spinal cord 36 is provided parallel to the sliding direction of the wedge body 6. Regardless of the rotational position of the eccentric shaft 36, the clamp body 35 can be pushed in parallel and is stable. FIG. 62 shows another embodiment in which the clamp body 35 has a surface parallel to the shoe surface instead of an inclined surface.

FIG. 63 shows another embodiment in which clamping is performed using screws 37.

In the embodiments described above, the back surface of the shoe 11 is a sloped surface, but this may be a surface parallel to the shoe surface, and the cover body 7 or clamp body 35 side may be a sloped surface.

Further, in all the embodiments, if there is a spring 15, even if the hand is removed, the spring 15 maintains a wedge effect, thereby preventing the product from falling. The present invention also includes structures obtained by combining the individual elements shown in the above embodiments.

In addition to the above embodiments, it is also possible to securely hold various items such as shelves and windows in any position along the support material, or conversely, by fixing a flexible locking device to a device equivalent to the support material.
