Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a round case, and more particularly, to a mounting structure for the lower end of a round case that can prevent the drop of the round case even if the upper end of the round case comes off.

A so-called round case is known as a shutter case for a heavy shutter or the like. The round case consists of a case plate formed by bending a metal plate into an arc shape when viewed in cross section. It is attached by engaging with the provided lower case stopper members. When locking the upper and lower ends of the round case, the case plate is elastically deformed in a direction that brings the upper end portion and the lower end portion closer to each other, and is inserted into the upper case stopper and the lower case stopper. By expanding with elastic force, the upper case stopper and the lower case stopper are engaged with each other, and the elastic force acting in the expanding direction maintains the locked state.

However, if vibration exceeding the elastic force of the round case acts due to the influence of an earthquake, etc., or for some reason (such as unintentional plastic deformation to improve the workability when mounting the round case), the round case will be damaged. If the elastic force is weak (in this case, the locked state of the upper end is likely to be released), the locked state of the upper end portion of the round case may be released. If the locking state of the upper end portion of the round case is released, the round case may fall without being held.

In Patent Document 1, the lower case retainer is a groove-shaped member with a lip, and when the upper end of the round case slips out of the upper case retainer and the round case is about to fall, the lower end of the round case is retained by the lower case. The round case is prevented from falling by receiving it with the lip part of the material.

However, in the locking structure for the lower end of the round case disclosed in Patent Document 1, the lower end portion of the round case and the lower case stopper are not completely fixed. rotation, etc.), the lower end of the round case may move in the direction of coming off the lower case retainer. When the locked state of the part is released and the round case rotates by its own weight, there is a possibility that the locked state of the lower end part of the round case is not maintained and the round case falls down. It is considered extremely unlikely that such a round case will fall, but it is desirable to be prepared just in case.

In one aspect, the tip of the lower end portion of the round case is in contact with the bottom portion.
In one aspect, the lower case stopper member has a second rising side rising from the bottom portion facing the rising side (first rising side), and the tip of the lower end portion of the round case is aligned with the bottom portion. It abuts on a corner ("bottom" in this specification also includes a corner) with the second rising side.
In addition, the tip of the lower end portion of the round case may be in contact with the second rising side.

In one aspect, the lower case stopper includes a locked portion above the bottom portion and away from the rising side,
A portion of the tip portion of the round case is locked or can be locked to the locked portion.
In one aspect, in the mounting state of the round case, a tip portion of the round case is locked by the locked portion, and a change in inclination of the lower end portion with respect to the rising side is restricted. .
In one aspect, in the mounting state of the round case, the tip portion of the round case is not locked to the locked portion, and when the inclination of the lower end portion with respect to the rising side changes, the A portion of the tip portion is locked to the locked portion.

In one aspect, the lower case stopper has a second rising side rising from the bottom facing the rising side (first rising side), and the locked portion is the upper end of the second rising side. is formed in
In one aspect, the locked portion is formed on a member (upper end of the rising piece of the separate member) separate from the member forming the bottom portion and the rising side.

The lower end portion of the lower inclined portion 72 on the tip side is inserted through the opening between the first upper horizontal side 63 and the second upper horizontal side 64 of the lower case stopper 6, and the second vertical side of the lower case stopper 6 is inserted. 62 and a predetermined position of the lower end portion of the lower inclined portion 72 of the case plate 7 (the portion located outside the lower case stopper 6) are connected by a hinge 8. As shown in FIG. More specifically, the hinge 8 includes a first plate 80 , a second plate 81 and a pivot shaft portion 82 . The second plate 81 is fixed to the outer surface of the second vertical side 62 of the lower case stopper 6 by screws S2. As shown in FIG. 2, the lower end portions of the case plates 7A to 7E are connected to the second vertical sides 62 of the lower case stopper member 6 via hinges 8 at both end portions in the width direction.

In the lower end portion of the round case, a portion positioned at the tip of the connecting portion of the lower case stopper member 6 with the second vertical side 62 is referred to as a tip portion 720 . In a state in which the lower end portion of the case plate 7 is attached to the lower case stopper member 6 , the tip portion 720 of the case plate 7 is engaged with or abuts on the lower case stopper member 6 . The pivot shaft portion 82 of the hinge 8 is located at the same height as or above the upper end (second upper horizontal side 64) of the second vertical piece 62, and the tip portion 720 of the case plate 7 is positioned at the pivot shaft. It is rotatable around the portion 82 . That is, the tip portion 720 of the case plate 7 is fixed to the lower case stopper 6 in such a manner that the tilted posture (tilt angle) of the tip portion 720 is variable according to the behavior of the case plate 7 .

At this time, the tip portion 720 rotates around the rotation shaft portion 82 so that the inclination gradient becomes small (FIG. 4), and the upper surface of the portion (first side) of the tip portion 720 closer to the tip 721 is It abuts and locks on the lower surface of the first upper horizontal side 63 (FIG. 5). The locking position of the tip portion 720 of the case plate 7 with respect to the lower case stopper 6 shown in FIG. 5 is defined as a second locking position (see FIG. 6). At the second locking position, the first side (front end side) of the tip portion 720 is locked by coming into contact with the first upper horizontal side 63 of the lower case stopper member 6 from below. The weight of the plate 7 provides a strong holding force. In addition, since the second side (base end side) of the tip portion 720 is fixed to the second vertical side 62 of the lower case stopper member 6 by the hinge 8, the tip portion 720 in the second locking position is fixed to the second side (base end side). The movement to side 2 (the direction in which the locked state of the distal end side is released) is restricted.

In FIG. 6, the lower inclined portion and the tip portion in the first locked position (first inclined posture) are indicated by 72 and 720, and the lower inclined portion in the second locked position (second inclined posture). The ramps and tip portions are indicated at 72', 720'.

In FIG. 7, the upper locking portion of the case plate 7 is locked to the upper case stopper 5, and the tip portion 720 of the lower end portion is locked to the lower case stopper 6 at the first locking position. . At the first locking position, the tip 721 of the tip portion 720 is in contact with the upper surface of the bottom side 60 of the lower case stopper 6, and the portion of the tip portion 720 separated from the tip 721 is the second upper horizontal side. It touches or is close to the tip of 64 (see FIG. 10).

7, when the upper bent side 73 of the case plate 7 deviates from the upper vertical side 53 of the upper case stopper member due to vibration or the like, the case plate 7, which has been elastically deformed in the locked state, expands. , and rotates forward (in the direction away from the upper case stopper 5, ie, the second side) and downward under its own weight.

At this time, the tip portion 720 rotates about the rotation shaft portion 82 so that the inclination gradient becomes small (FIG. 8), and the upper surface of the portion (first side) of the tip portion 720 closer to the tip 721 is It abuts and locks to the lower surface of the first upper horizontal side 63 (FIG. 9). The locking position of the tip portion 720 of the lower end portion of the case plate 7 with respect to the lower case stopper 6 shown in FIG. 9 is defined as a second locking position (see FIG. 10). At the second locking position, the first side (front end side) of the tip portion 720 is locked by coming into contact with the first upper horizontal side 63 of the lower case stopper member 6 from below. The weight of the plate 7 provides a strong holding force. In addition, since the second side (base end side) of the tip portion 720 is fixed to the second vertical side 62 of the lower case stopper member 6 by the hinge 8, the tip portion 720 in the second locking position is fixed to the second side (base end side). The movement to side 2 (the direction in which the locked state of the distal end side is released) is restricted.

In FIG. 10, the lower inclined portion and tip portion in the first locked position (first inclined posture) are indicated by 72 and 720, and the lower inclined portion in the second locked position (second inclined posture). The inclined portion and tip portion are indicated by 72'' and 720'', and the lower inclined portion and tip portion on the way from the first locking position to the second locking position are indicated by 72' and 720'.

[Third embodiment]

In FIG. 11, the upper locking portion of the case plate 7 is locked to the upper case stopper 5, and the tip portion 720 of the lower end portion is locked to the lower case stopper 6 at the first locking position. . At the first locking position, the tip 721 of the tip portion 720 is in contact with the upper surface of the bottom side 60 of the lower case stopper 6, and the portion of the bottom end portion 720 separated from the tip 721 is the second upper horizontal side. It touches or is close to the tip of 64 (see FIG. 14). As is clear from comparison with FIG. 7, the inclination of the first locking position is steeper than that of the second embodiment.

11, when the upper bent side 73 of the case plate 7 deviates from the upper vertical side 53 of the upper case stopper member due to vibration or the like, the case plate 7, which has been elastically deformed in the locked state, expands. , and rotates forward (in the direction away from the upper case stopper 5, ie, the second side) and downward under its own weight.

The locking position of the tip portion 720 of the lower end portion of the case plate 7 with respect to the lower case stopper member 6 shown in FIG. 13 is defined as a second locking position (see FIG. 14). At the second locking position, the first side (front end side) of the tip portion 720 is locked by coming into contact with the first upper horizontal side 63 of the lower case stopper member 6 from below. The weight of the plate 7 provides a strong holding force. In addition, since the second side (base end side) of the tip portion 720 is fixed to the second vertical side 62 of the lower case stopper member 6 by the hinge 8, the tip portion 720 in the second locking position is fixed to the second side (base end side). The movement to side 2 (the direction in which the locked state of the distal end side is released) is restricted.

5, 9, and 13, in the second locking position (second tilted posture), if the dimension of the case plate 7 is reduced, the case relative to the lower case stop member 6 will be more likely to be displaced. There is a tendency that the inclination angle of the tip portion 720 of the plate 7 becomes large and the engagement becomes shallow. In particular, as shown in FIG. 13, when the case size is small, the engagement of the tip portion 720 with respect to the first upper horizontal side 63 is shallow and the inclination is large. 2, if vibration or the like acts, there is a risk that the locked state between the tip portion 720 of the case plate 7 and the first upper horizontal side 63 will be disengaged.

A modification of the lower case stopper 6 is shown in FIG. In the modification shown in FIG. 15, the locked portion of the case plate 7 to which the tip portion 720 is locked is extended to the second side, thereby preventing the tip portion 720 from being disengaged as much as possible. there is A specific description will be given below.

As is clear from comparison with FIG. 13 , in the tip portion 720 of the case plate 7 , a portion spaced apart from the tip 721 is engaged with the first upper horizontal side 63 ′, and the second side of the tip portion 720 Movement in (the direction to get out) is restricted (fixed to the lower case stopper 6 via the hinge 8), thereby preventing the tip portion 720 from being disengaged as much as possible. .

In the example shown in FIG. 15B, a locked member 9, which is a separate member, is incorporated inside the lower case stopper member 6. In the example shown in FIG. In a cross-sectional view, the locked member 9 has a bottom portion 90, a vertical side 91 rising from a first side end of the bottom portion 90, and a substantially U-shaped side extending horizontally from the upper end of the vertical side 91 to the second side. It has In the illustrated embodiment, the second side end of the bottom portion 90 of the locked member 9 is adjacent to the lower end of the second vertical side 62 of the lower case stop member 6, and the vertical side 91 is the second end of the lower case stop member 6. The locked side 92 extends beyond the first upper horizontal side 63 of the lower case stopper 6 to the second side. As in FIG. 15(A) , the distal end portion 720 of the case plate 7 is engaged with the engaged side 92 at a portion spaced apart from the distal end 721 and is located on the second side of the distal end portion 720 (the exit direction). ) to prevent the tip portion 720 (fixed to the lower case stopper 6 via the hinge 8) from being disengaged as much as possible.

FIG. 16 is a view of the case plate 7 rotating in the state shown in FIG. Dropping is prevented by being suspended from the material 6. - 特許庁As described above, in this embodiment, the lower end portion of the case plate 7 and the second vertical side 62 of the lower case stopper member 6 are connected via the hinge 8 , so that the tip of the lower end portion of the case plate 7 should be prevented by any chance. Even if the portion 720 is disengaged and the case plate 7 rotates and is about to fall, the connection between the lower end portion of the case plate 7 and the lower case stopper member 6 is maintained, thereby preventing the case plate from falling.
