By releasing the holding of the support rod B by a hand or the like in such a state, the support rod B tilts in the direction of the arrow y by its own weight and faces the hole edge c ′ of the opening / closing body C. The hole edge c ″ (actually, the hole edge on the side of the rotation base of the opening / closing body C that is in the open state) is set to the seat 1 described above.
The bearing surface 1a functions as a bearing (see FIG. 8).

When the support member A is inserted without holding the support rod B by a hand or the like, the engagement protrusion 2c of the support member A is positioned in the engagement hole c. As shown in FIG. 9, the insertion portion 2 of the support rod B falls in the direction of the arrow y toward the hole edge c ″ of the engagement hole c, and this hole edge c ″ and the engagement protrusion of the support member A. 2c and the upright wall portion between the bearing surface 1a of the seat portion 1 are in contact with each other, and the opening / closing body C is dropped in the direction of m, and the hole edge c ″ of the engaging hole c is the support rod B in the same manner as described above. It is supported on bearing surface 1a.

In such a state, when a force of leaning toward the direction m'is applied to the opening / closing body C, as shown in FIG. 9, the hole edge c ″ of the opening / closing body C is engaged with the engaging protrusion of the support member A. Abutted on part 2c,
The release of the support rod B and the opening / closing body C is prevented.

Further, even if the force of such leaning out disappears, since the support rod B falls toward the side of the arrow y, the hole edge c ″ of the opening / closing body C has the engaging protrusion 2c and the seat portion 1. While being in contact with the rising wall portion between them, they are pushed again in the direction of m, and the engaged state of both is maintained.

The insertion portion 2 that is bulged from the seat portion 1 is located on the lower side Y when the support rod B is tilted and used, that is, on the lower side in the undulating direction of the support rod B. It is raised from the seat 1 so that the bearing surface 1a is always left in the portion where it is located.

Further, the insertion portion 2 is provided with a rising wall portion 2a which stands up at a right angle from the position of the bearing surface 1b of the seat portion 1 on the side which becomes the upper side Y'when the support rod B is rotated and raised.

Further, the insertion portion 2 including the rising wall portion 2a is provided at its tip end side with an inclined surface 2b which is inclined so as to project from the upper side Y'to the lower side Y. An engaging projection 2c, which is parallel to the bearing surfaces 1a and 1b of the seat 1, is provided on the upper side of 2b in the direction of the lower side Y. That is, the insertion portion 2 is provided with an inclined surface 2b facing the upper side in the up-and-down direction of the support rod B at the tip end side thereof, and moreover, the ups and downs of the support rod B are provided at the tip end portion of the insertion portion 2. The engaging protrusion 2c is provided so as to protrude downward in the direction.

That is, this engaging protrusion 2c is the lower side Y of the seat 1.
The part facing the bearing surface 1a at is formed as a jaw 2c '. Further, the seat side of the rising wall 2d between the seat 1 and the jaw 2c 'of the engaging projection 2c is formed as an inclined part 2e which is slightly raised toward the bearing surface 1a, and is opened and closed. Body C is the bearing surface at once
It avoids the inconvenience of dropping to 1a.

Also, the engaging projection 2c of the insertion portion 2 is raised only at the central portion.
2f, the contact resistance of the engaging hole c to the hole edge c ′ is reduced, and smooth insertion is aimed at, and at the same time, the material used is reduced.

The insertion portion 2 having such a configuration is inserted into the engagement hole c of the opening / closing body C by using the inclined surface 2b, and the opening / closing body C in this assembled state and the insertion portion 2 are inserted. At the time of detaching, the engaging projection 2c of the insertion portion 2 is shaped and dimensioned to abut on the peripheral surface of the hole edge of the engaging hole c of the opening / closing body C.

That is, the insertion portion 2 has a shape and dimensions that can be inserted into the engagement hole c of the opening / closing body C, and
An imaginary line X passing through the protruding tip of the engaging projection 2c and parallel to the support rod B, and an inclination of the inclined surface 2b on the side opposite to the side where the engaging projection 2c is provided. A surface end, in this illustrated example, passes through an edge where the rising wall portion 2a and the inclined surface 2b are in contact with each other, and is orthogonal to an imaginary line X'parallel to the support rod B, and each of these imaginary lines. The insertion portion 2 is configured such that the dimension of the imaginary line x connecting X and X'is larger than the dimension of the engagement hole c in the up-and-down direction of the support rod B.

Next, the mounting cylinder portion 3 has a window hole 3a communicating with the inside of the cylinder in the direction of the upper side Y'and the lower side Y.
A pair of engagement pieces 3b, 3b is provided on the inside of the cylindrical portion 3 on the 3a so that the tip end side thereof projects in an inclined state.

Further, as a means for attaching the support member A to the inserted support rod B so as not to rotate, that is, as one means of rotation preventing means, a groove 3c is formed in the peripheral wall from the inlet side of the tubular portion 3 toward the inner depth. Is provided.

Next, the support rod B is an engaging portion b which is gradually thickened in a direction around the tip end side axis, that is, in the circumferential direction from the tip end side of the support rod B toward the base side.
The slanted surface of the engaging portion b allows the engaging pieces 3b, 3b of the tubular portion 3 to be elastically deformed outward and inserted into the bearing member A.

Along with this insertion, the jaws b'at the engaging portion b of the support rod B are elastically engaged with the tip edges of the engaging pieces 3b, 3b, respectively, so that both are integrally assembled.

When the support rod B is inserted, a rotation preventing projection b ″ serving as the other means of the rotation preventing means is provided on the circumferential side of the support rod B, and the rotation preventing projection b ″ is provided.
Is engaged with the groove 3c of the cylindrical portion 3, the rotation of the support member A attached to the support rod B is prevented.

Further, the engaging hole c of the opening / closing body C, which is a typical example of the hood inner, has a concave portion c having a shape in which the seat portion 1 of the support member A is effectively accommodated, as shown in FIGS. 12 and 13. It is ideal that the support member A of the support rod B has a smooth insertion support and a stable support condition.

The hole diameter of the engaging hole c, the size of the inserting portion 2, the protruding width of the engaging protruding portion 2c, and the like are mutually determined in consideration of the degree of inclination of the inclined surface 2b of the inserting portion 2 and the like. However, it is not necessarily limited to the illustrated example.

Further, as a matter of course, one hole diameter of the engagement hole c is configured to be narrower than the dimension from the rising wall portion 2a of the insertion portion 2 to the engagement projection portion 2c, and the engagement projection portion 2c is It is configured to be reliably supported by the hole edge c ″ of c.

Next, regarding the support for the opening / closing body according to the above embodiment,
An example of the operation will be described with reference to FIGS.

First, in order to maintain the opening / closing body C in the open state, the opening / closing body C is lifted above the supporting state and the opening / closing body C is opened.
Similarly, the insertion portion 2 of the supporting member A of the support rod B, which is similarly erected in the engaging hole c, is inserted. At this time, the support rod B is supported by a hand or the like.

To insert such a bearing member A, the inclined surface 2b of the insertion portion 2 is moved to the opening / closing body C by positioning the engagement protrusion 2c of the insertion portion 2 and a part of the inclined surface 2b in the engagement hole c. It contacts the hole edge c ′ of the engaging hole on the tip side (upper side when opened), is pushed down toward the arrow y side by this hole edge c ′, and is gradually inserted into the hole c. (See Figure 11).

The hole edge c'of the engaging hole c and the inclined surface 2b of the insertion portion 2
When the contact with is released (see FIG. 10), that is, when the hole edge c ′ of the engaging hole c is positioned on the rising wall portion 2a, the opening / closing body C falls in the direction of m, and the supporting member A It is supported by the bearing surface 1b of the seat 1.

When the support rod B is released from the holding state in such a state, the support rod B tilts in the direction of the arrow y by its own weight, and the hole edge c ″ facing the hole edge c ′ of the opening / closing body C. With respect to (the hole edge on the rotation base side of the opening / closing body C that is actually opened), the bearing surface of the seat 1
1a functions to support this (see Fig. 8).

In addition, insert the above-mentioned support member A into the support rod B
When the engaging projection 2c of the support member A is positioned inside the engaging hole c, the supporting member A is moved toward the hole edge c ″ of the engaging hole as shown in FIG. The insertion portion 2 of the support rod B falls in the direction of the arrow y, and the hole edge c ″
And the rising wall portion 2d between the engaging projection 2c of the bearing member A and the bearing surface 1a of the seat portion 1 are in contact with each other, and the opening / closing body C is dropped in the direction of m. The hole edge c ″ of the hole c is supported by the support surface 1a of the support rod B.

 Next, the function of preventing leaning will be described.

When a pushing force in the direction of m ′ acts on the opening / closing body C supported on the top, the hole edge c ″ of the opening / closing body C is engaged with the support member A as shown in FIG. The support rod B and the opening / closing body C are prevented from being released by coming into contact with the jaw 2c 'of the abutting portion 2c.

Further, even if such a force of pulling out disappears, since the support rod B falls toward the side of the arrow y, the hole edge c ″ of the opening / closing body C supports the engaging projection 2c and the seat 1. While being in contact with the rising wall portion 2d between the surface 1a and the surface 1a, it is dropped again in the direction of m, and the engagement state of both is maintained.

Next, a case where an external force is applied to the support rod B will be described.

Even if the support rod B is tilted in the direction of the arrow y ', the rising wall portion 2a of the support rod B surely abuts the hole edge c'of the opening / closing body C, so that the opening / closing body C is opened. Unless they are pushed upward, the engagement state between them is maintained as it is.

Therefore, even if the support rod B is erroneously pushed in the direction of the arrow y ′, the opening / closing body C is reliably supported by the support rod B.

 Next, the operation of closing the opening / closing body C will be described.

First, as shown in FIG. 10, the opening / closing body C is lifted in the direction of m ', and the hole edge c'of the engaging hole c is the inclined surface of the insertion portion 2.
With the support rod B positioned at 2b, move the arrow y '
The engagement between the two is released by rotating in the direction of (see FIG. 11).

Of course, without opening the support rod B in the direction of the arrow y ′, the opening / closing body C is sufficiently lifted in the direction of m ′, and in this state, a movement corresponding to the protrusion width of the engaging protrusion 2c of the insertion portion 2 is performed. May be brought to the support rod B.

(Effect of the device) The support for the opening / closing body according to the present invention is easy to handle due to the characteristic structure and function of the above, and the structure of the support member A is simple and the molding cost is low. Nevertheless, the support member A rotates with respect to the support rod B even if an unexpected external force such as gust of wind is applied to the opening / closing body C because the opening / closing body C is reliably supported in the open state. The opening / closing body C and the support are never disengaged.

Further, even when an unexpected external force is similarly applied to the support rod B supporting the opening / closing body C, the engagement state can be maintained similarly.

Further, an engagement piece 3b engaged with an engagement portion b of the support rod B inserted into the mounting cylinder portion 3 is provided on the inner side of the mounting cylinder portion 3, and the support rod 3b is further provided. Since the B and the mounting tube portion 3 are provided with rotation preventing means for preventing co-rotation of both members, the supporting member A can be easily inserted and assembled into the support rod B. At the same time, the support member A assembled to the support rod B is prevented from rotating, and the support member A is always assembled and held in the same direction as the mounting direction.
