Description

  The present invention relates to a panel shutter in which a plurality of panels connected by a chain are sequentially drawn out or pulled to open and close these panels along a guide rail.

Conventionally, in this type of invention, when the slack of the chain is detected by a limit switch, for example, as described in Patent Document 1, a driving source for feeding or pulling the chain is stopped. In some cases, the opening / closing operation by a plurality of panels is stopped.
In addition, in the invention described in Patent Document 2, a seat plate capable of moving up and down is provided at the lower end of the lowermost panel, and it is detected by a microswitch that the seat plate has been raised by contact with an obstacle. The opening / closing operation of the panel is stopped by the detection signal.

By the way, in the invention which concerns on patent document 1, there exists a possibility that the state cannot be detected, for example, when a chain breakage arises.
Moreover, in the invention which concerns on patent document 2, since it is a structure which contacts an obstacle, there exists a possibility of giving an impact to an obstacle.
Therefore, it is proposed to have a fall prevention device that can sense even when the chain is broken, etc., and a sensing unit that can sense obstacles without contact, but it must receive a relatively heavy panel to prevent falling, Since it is necessary not to interfere with the structural members at the end of the panel in the width direction such as a chain, and the space in the guide rail has no allowance, a contrivance is required.

  In FIG. 4, the arrangement of the electric wires in the electric wire guide means 60 in the storage unit 30 is omitted. For example, the electric wires are closer to the housing P than the portion of the panel connection chain 13 that extends substantially vertically. The upper end side is electrically connected to a control circuit (not shown).

According to the storage unit 30 having the above-described configuration, when the sprocket 32 rotates in one direction (clockwise according to FIG. 4), the plurality of panels 11a and 11b are sequentially pulled upward by the chain member 13. And while the panels 11a and 11b are maintained in a substantially vertical shape by the guide portion 35, the moving direction is changed by the outer peripheral portion of the sprocket 32, and further obliquely downward by the storage rail 34 (diagonally downward to the right according to FIG. 4). Led to.
Further, when the sprocket 32 rotates in the reverse direction (counterclockwise according to FIG. 4), the plurality of panels 11a and 11b are sequentially drawn out backward (to the left according to FIG. 4) on the housing side by the chain member 13. It is. Each drawn-out panel 11a (or 11b) moves downward in the guide rail 20 while being suspended by the chain member 13 and maintained in a substantially vertical shape.

As the panels 11a and 11b open and close, the panel connecting chain 13 is guided to the insertion portion 36b of the support protrusion guide 36 and moves in a substantially vertical shape.
When slack occurs in the panel connection chain 13 during the movement or stop, the panel connection chain 13 contacts the actuator portion of the slack limit switch 37 on the opposite side of the upper portion 36a in the panel thickness direction. Therefore, an abnormal signal is transmitted from the limit switch 37, and a predetermined control operation such as stopping of the drive mechanism 33 is performed by a control circuit (not shown).

Further, during the closing operation of the opening / closing body 10, when an obstacle is present below the lowermost panel 11 a, the obstacle is non-contact sensed by the non-contact sensing unit 50, and according to the sensing signal. A control circuit (not shown) stops or reverses the drive mechanism 33.
In the unlikely event that the panel connection chain 13 is broken and the panel 11a falls, the dropped panel 11a can be received by the retractor device 40 and stopped.

  The retractor device 40 is a device used for a vehicle seat belt or the like. The retractor device 40 is a flexible long member 41 that generates tension due to the weight of the panel 11a during an abnormal stop, and a base of the flexible long member 41.

  The reel device 42 includes a substantially U-shaped support bracket 42b fixed near the housing P of the storage case 31, a winding body 42a rotatably supported by the support bracket 42b, and the winding body 42a. A biasing means (not shown) for biasing in the winding direction, and the winding body 42a rotates in the feeding direction against the biasing force of the biasing means, and the rotation speed becomes a specified value or more. And a lock means (not shown) for stopping the rotation of the winding body 42a.

The locking means restrains the winding body 42a from being unrotatable when the feeding rotation speed of the winding body 42a becomes equal to or higher than a specified speed, for example, a structure in which a member that moves due to centrifugal force is locked to a stationary part. Any structure can be used.
The specified speed is an appropriate speed higher than the normal closing speed of the opening / closing body 10.
As another example of the reel device 42, when the take-up rotational acceleration of the take-up body 42a is equal to or higher than a specified acceleration, the take-up body 42a may be restrained so as not to be unwound.

The retractor device 40 according to the preferred embodiment shown in the figure has the winding body 42a disposed above the guide rail 20, and the flexible long member 41 is positioned on the housing side of the opening / closing locus of the panel 11a in the panel thickness direction (see FIG.

As another example, the retractor device 40 is fixed in the storage case 31 in a state of being separated from the housing P, or is a lower body than the opening / closing locus of the panel 11a below the sprocket 32 and the guide portion 35. It is also possible to arrange it on the side (in FIG. 4, the right side of the chain line).

Therefore, according to the panel shutter 1 of the said structure, since the flexible elongate member 41 of the retractor apparatus 40 is arrange | positioned near the housing P, the load when the retractor apparatus 40 receives panel 11a, 11b is received. Accordingly, it is possible to prevent the configuration of the storage case 31 or the like that supports the retractor device 40 from being deformed or damaged.
Moreover, the flexible elongate member 41 and the wire guide means 60 interfere with the support projections 12 arranged on the width direction end portions of the panels 11a and 11b, the panel connecting chain 13, the guide projections 14 and the like. Can be prevented.

  In addition, according to the said embodiment, although the front-end | tip part of the flexible elongate member 41 was fixed to the panel 11a, as another example, the flexible elongate member 41 extended | stretched straddles the lower end of the panel 11a. It is also possible to adopt a mode in which the distal end portion of the flexible long member 41 is fixed to a stationary part such as the guide rail 20 or the storage case 31. Also in this aspect, the panel 11a when it suddenly falls can be received by the midway part of the flexible long member 41 in the length direction.

  Moreover, according to the said embodiment, although the electric wire of the non-contact sensing part 50 is guided in the accommodating part 30 by the electric wire guide means 60 shown in FIG. 3, as another example, the said electric wire is carried out with a cord reel. It is also possible to adopt a mode in which the wire is wound or a mode in which the electric wire is guided into the guide rail 20 by a pulley mechanism.

  Further, according to the above embodiment, as a means for guiding the non-contact sensing unit 50 in the vertical direction, the guided convex part 51b on the non-contact sensing part 50 side and the concave guide member 21 on the guide rail 20 side are fitted together. However, as another example, the concave-convex relationship can be reversed as in the panel shutter 2 shown in FIG.

  Moreover, according to the said embodiment, although it was set as the structure which does not interfere both the flexible elongate member 41 and the electric wire guide means 60 with the panel connection chain 13, as another example, the electric wire guide means 60 and a panel connection chain It is also possible to adopt a structure in which only one of the terminals 13 does not interfere with the panel connection chain 13.

  Next, the panel shutter 2 shown in FIG. 5 will be described, but the same reference numerals are given to portions that are substantially the same as those of the panel shutter 1 described above, and a detailed description thereof is omitted.

  The panel shutter 2 has a configuration in which the guide rail 20 is replaced with the guide rail 20 ′ and the slide body 51 is replaced with the slide body 51 ′ with respect to the panel shutter 1.

  The guide rail 20 ′ is a member having a substantially concave cross section extending between the contact target portion q and the storage portion 30 on each of both end sides in the width direction of the opening / closing body 10. A guide protrusion 21 ′ is integrally formed on the bottom of the guide rail 20 ′ so that the tip end side extends in the panel thickness direction and continues in the vertical direction.

Further, the slide body 51 ′ has a configuration in which the guided convex portion 51b of the slide body 51 is replaced with a guided concave portion 51c.
The guided recessed portion 51c is a concave groove formed so as to be fitted to the distal end side of the guide projection 21 ′ and to slide in the vertical direction, and is locked to the distal end side of the guide projection 21 ′ at the opening edge portion thereof. Inward projections 51c1 and 51c1 are provided.

Therefore, according to the panel shutter 2 having the above-described configuration, the guide protrusion 21 ′ is formed integrally with the guide rail 20 ′, so that the productivity is good.
Moreover, since the guided recess 51c of the slide body 51 ′ is fitted to the guide protrusion 21 ′ that extends in the panel thickness direction, it is effective that the slide body 51 ′ is detached from the guide protrusion 21 ′. Can be prevented.

It is designed to reciprocate up and down.
The engagement / disengagement protrusion 71a is a member having a substantially inverted triangular cross section (see FIG. 8) having a square portion on the lower end side, and is continuous in the width direction of the middle pillar 70 (left and right according to FIG. 7). It is formed in a scale.

The second slide portion 74 has an upper end portion inserted into the main body portion 73 and a lower end portion protruding downward from the main body portion 73 and exposed.
The second slide portion 74 engages with the shaft-like member 71b of the first slide portion 71 and is slidable in a vertical direction by a predetermined amount. The urging member 75 supported by the main body portion 73 (according to the illustrated example). The coil spring is biased downward.
At the lower end of the second slide portion 74, an elastic member 74a is provided across the width direction of the middle column 70 in order to improve the adhesion with the contact target portion q.

When the first slide portion 71 is at the position where the engagement / disengagement protrusion 71a protrudes (the position shown in FIGS. 7 and 8), the second slide portion 74 compresses the elastic member 74a to the contact target portion q. It is in contact.
When the first slide portion 71 slides upward, the second slide portion 74 is brought into contact with an engagement member 71b1 (a nut according to the illustrated example) fixed to the lower end side of the shaft-like member 71b. , Move upward and away from the contact target part q. In this state, the middle pillar 70 can be moved or rotated in the width direction.

Moreover, the recessed part 80 is comprised by embedding the box-shaped body 81 which comprised the opening-and-closing member 82 in the contact | abutting object site | part q (refer FIG. 9).
The box-shaped body 81 is a metal box-shaped member having an opening 81a upward. The opening 81 a is formed so that the engaging / disengaging protrusion 71 a of the first slide portion 71 is inserted.
According to the illustrated example, the opening / closing member 82 is two plate-like members, and prevents foreign matter from entering the box-like body 81. The opening / closing member 82 is pressed downward by the engaging / disengaging protrusion 71a, and is biased in the closing direction by a biasing force of a biasing member (not shown) (for example, a coil spring or a spring-loaded hinge).

  Therefore, the middle pillar 70 having the above-described configuration is configured so that the engagement / disengagement projection 71a having a substantially inverted triangle shape is engaged / disengaged in the length direction of the recess 80, and thus, for example, a cylindrical shape provided in the contact target portion q. Compared with the prior art or the like in which two protrusions are fitted into the holes, positioning is easy.

As other examples of the opening and closing member 82, a single plate member that opens and closes downward, a plate member that is made of an elastic body such as rubber, and the like are provided with slits that are elastically opened and closed. Good.
Further, as another example of the recess 80, it is possible to adopt a mode in which the opening / closing member 82 is omitted from the above configuration.
