First embodiment

FIG. 1 shows an example in which a swing door is assembled as a baby gate (pet gate) by applying the present invention.
In this embodiment, a rotatable door 11 is attached to the shaft pipe 5 fixed to the wall surface. As shown in FIG. 2, fixed parts 4 are fixed at two places of the shaft pipe 5 so as not to rotate and slide.
The second part 2 is inserted into the upper part of the fixed part 4 into the shaft pipe 5 so that the lower part of the second part 2 meshes with the upper projections and depressions of the fixed part 4.・ It is placed so that it cannot slide.
A pipe joint 3, which is a part of the door, is inserted into the shaft pipe 5 so as to be slidable and rotatable. Between the pipe joint 3 and the second part 2, the first part 1 rotates relative to the pipe. It is inserted so that it can move and slide. The upper part of the first part 1 and the lower part of the pipe joint 3 are engaged by uneven engagement, and the first part 1 cannot be rotated relative to the pipe joint 3.
As a result, the second component 2 that cannot slide and rotate with respect to the shaft pipe 5 and the first component 1 that can slide and rotate are disposed to face each other. The first component 1 and the second component 2 each have two V-shaped inclined surfaces 1A and 2A that are substantially complementary to each other.
In FIG. 1, the first and second parts 1 and 2 and the fixed part 4 are shown as a part set 10.
From the door closed 11 (state where the first and second inclined surface 1A-2A is in contact), open the door 11 (rotating) the first component 1 is slid upward with the door 11. When the door 11 is released in this state, the first component 1 is pressed against the second component 2 by the gravity of the door 11. At this time, the slope 1A slides on the slope 2A, and the first component 1 slides downward while rotating together with the door 11. Thereby, the door 11 returns to the closed state.
In FIG. 2, the pipe joint 3 is illustrated as a resin joint, but a metal rotary joint that can be fixed to the first and second parts 1 and 2 or may be integrated.

Modification 1 of the first embodiment

FIGS. 3A and 3B show a modified example of the slope of the first embodiment. In this example, a concave portion 2B2 is provided at the top of the second slope 2B, and a convex portion 1B1 that engages with the concave portion 2B2 is provided at the top of the first slope 1B. It is.

The convex portion 1C1, the concave portion 2C2, and the braking slope 2C1 exhibit the same function as in the first modification, and the description thereof is omitted. The first inclined surface 1C and the second inclined surface 2C have orthogonal surfaces 1C3 · 2C3, 1C4 · 2C4, respectively, in the inclined surfaces. When the first component 1 is rotated, the first component 1 cannot be rotated in a state where the 1C3 and 2C3 are in contact with each other.
In addition, even if the vehicle overruns beyond the return position when returned, 1C4 and 2C4 come into contact at about 10 ° and return to the return position after stopping. Moreover, even if it tries to rotate in the reverse direction, it becomes impossible to rotate at about 10 °, and it becomes a swing door that rotates in the range of 0 to −90 °.

Second embodiment

FIG. 5 shows a second embodiment in which the present invention is applied to a one-way revolving door used in an event venue or the like.
The revolving door 11 has four rectangular pipe assemblies around the shaft pipe 5 and is fixed in a cross shape in two upper and lower stages. The fixed pipe assembly 12 is fixed to the floor as a fence, and three pipe joints 3 are fixed to the front end thereof. The shaft pipe 5 is inserted into the three pipe joints 3 so as to be rotatable and slidable. Yes.
In the second embodiment, the component set 10 of the first embodiment is arranged in the reverse order to that of the first embodiment. That is, the first component 1, the second component 2, and the fixed component 4 are arranged from the bottom.
FIG. 6 shows a development view of the slopes 1D and 2D of the first and second parts 1 and 2 used in the second embodiment. In the first embodiment, the end surfaces of the first and second parts 1 and 2 are configured by two surfaces each having the same angled slopes 1A and 2A, but in this embodiment, each is configured by four surfaces. Further, reverse rotation preventing surfaces 1D1 and 2D1 are provided on the inclined surfaces 1D and 2D, respectively.
The operation of this embodiment will be described below.
When the door 11 is rotated from the initial state (rotation angle 0 °) by the person leaving the event, the shaft pipe 5, the fixed component 4, and the second component 2 integrated with the door 11 are also rotated upward by the slope 1 </ b> D. Lifted. When it rotates beyond 45 °, it rotates while descending the slope 1D by its own weight and stops at a position of 90 °. At this position, the reverse rotation preventing surfaces 1D1 and 2D1 are engaged with each other to prevent reverse rotation. Therefore, it is possible to prevent a person who has once left the venue from entering again.

Third embodiment

FIG. 7A shows the first and second parts 1 and 2 of the third embodiment. In this embodiment, a slope cover 6 is provided on the first component 1. The slope cover 6 covers a gap S formed between the slopes 1A and 2A by relative rotation of the first and second slopes 1A and 2A. As a result, fingers, clothes, and the like are prevented from being caught in the gap S when both the parts 1 and 2 head in the proximity direction due to their own weight.
The slope cover 6 may be provided on the second component 2. FIG. 7-2 is a diagram showing a cross section of the slope cover 6 in this case . A second slope 2A is integrally formed inside the cover.

  In each embodiment, the first and second parts 1 and 2 are separated from the pipe joint 3 and the fixed part 4, but they may be integrated into the first and second parts.

Fourth embodiment

FIG. 8A shows the first component 1, the fitting adapter 12, and the pipe joint 3 of the fourth embodiment.
This embodiment shows an embodiment of the present invention using various existing general-purpose joints. The first component 1 is connected via a fitting adapter 12 having an inner diameter capable of receiving a cylindrical portion of the general-purpose L-shaped joint 3. Is connected to the joint 3. The fitting adapter 12 includes a fixing portion 12A that is fixed to the joint 3 by fitting or bonding, and a serration 14 that is fitted to the first component 1 so as not to be relatively rotatable. In this embodiment, serrations 1E are also required on the inner peripheral surface of the first component 1. The fixing portion 12A is provided with slits 13 for receiving the ribs 31 at four locations so that the fixing portion 12A can be applied to an existing five-way joint. A typical example of an existing joint is shown in Fig. 8-2.
The advantage of fitting with serrations 14 and 1E is that fine phase angle adjustment can be achieved by fitting one groove at a time. Further, as shown in FIG. 8C, the adapter 12 and the first component 1 may be integrated and produced.
In the present embodiment, the first component 1 has been described, but this may be applied to the second component. Furthermore, slopes 1A and 2A may be provided at one end of the existing joint and used as the first and second parts.

In FIG. 2, the hinge / pipe joint 3 is a T-shaped joint that connects two pipes in a T-shape, but an L-shaped joint can also be used.
In FIG. 2, the T (L) type joint is movable (door side) with respect to the shaft pipe 5, but when this figure is inverted, the hinge / pipe joint 3 is fixed on the fixed side (pipe fence, etc.).
The set of the second component, the fixed component 4 and the rotary shaft pipe 5 can be the movable side (door, etc.). FIG. 5 corresponds to this.
Further, integrating the T / L joint 3 and the first component, and integrating the second component 2 and the fixed component 4 can achieve the same effect in terms of obtaining a rotation control function. However, the ease with which the first and second parts 1 and 2 can be removed and replaced is impaired.

A rotation function is added to the hinge function, which is one of the methods of using pipe products that are already widely used in society, and it expands the applications of pipe products.
