Description

The present invention relates to an open / close counting device that counts the number of times of opening and closing a door body that opens and closes a building opening, and more particularly to an open / close counting device that counts the number of times of opening and closing a door in an overhead door.

For doors such as overhead doors, in order to ensure the function and safety of the product, inspection and maintenance are performed based on the number of times of opening and closing, and durability is managed. In particular, in a manual opening / closing door, the number of opening / closing of the door body is counted using an opening / closing counting device.

Although it is possible to consider using a commercially available general-purpose counter as the open / close counting device, the general-purpose counter is not necessarily limited to shock resistance required for the open / close door (for example, an overhead door), operating temperature (−10 to 40 ° C.), and count error. There is a problem that conditions such as (± 1% or less) cannot be satisfied.

Patent Document 1 discloses an open / close counting device for an overhead door, but there is no specific disclosure of each element constituting the open / close counting device.

When the operation lever is rotated in the second direction, the rotation of the operation lever is not transmitted to the rotation lever, and the number of times is not counted.
The open / close counting device is provided on either the door body or the housing forming the opening of the building that opens and closes the door body, and the other is provided with a contacted portion that contacts the operating lever of the open / close counting device. In the embodiment described later, the open / close counting device is provided on the door body and the contacted portion is provided on the guide rail. However, the open / close counting device may be provided on the guide rail and the contacted portion may be provided on the door body. Good. Further, in the embodiment described later, the operating lever of the open / close counting device rotates in the first direction when the door body is opened, but the operating lever rotates in the first direction when the door body is closed. You may comprise as follows.

In one aspect, the locking of the first rotating element and the second rotating element is performed by bringing the surface portions into contact with each other.
In a more specific example, each of the first rotation element and the second rotation element includes a protrusion that protrudes in the length direction of the rotation shaft, and the surface portions of the protrusions come into contact with each other. I am doing so.

In one mode, the 1st rotation element is provided with the 1st spring element for maintaining the normal posture of the operation lever.
In a more specific mode example, the normal posture of the actuating lever is a horizontal posture, but the normal posture is not limited to the horizontal posture, and the normal posture depends on the configuration of the door device to which the present invention is applied.

An open / close counting device 6 is provided on the surface of the panel 2 on one end side in the width direction. The open / close counting device 6 includes a needle-like operating lever 60 that extends horizontally toward the guide rail 1 side. The panel 2 to which the open / close counting device 6 is attached is not limited to the second panel 2 from the bottom, and the open / close counting device 6 may be provided on another panel 2.

In the guide rail 1, when the door body is in the fully closed posture, the contacted body 7 is positioned directly above the distal end side of the operating lever 60 of the open / close counting device 6 provided on the panel 2 at the second stage from the bottom. It is provided. The contacted body 7 includes an inclined lower guide part 70, an inclined upper guide part 71, and a locking part 72 formed between the lower guide part 70 and the upper guide part 71. Yes. When the door body in the fully closed position moves up, the operating lever 60 of the open / close counting device 6 provided on the panel 2 is guided to the locking portion 72 while being in contact with the lower guide portion 70 and locked to the locking portion 72. Then, it is rotated downward to count the number of opening and closing. In the embodiment, the open / close counting device 6 is provided on the door body side, and the contacted body 7 is provided on the housing side (guide rail 1). On the contrary, the open / close counting device is provided on the housing side and the open / close counting device is provided on the door body side. A contact body may be provided. In the embodiment, the number of times of opening and closing is counted when the door is raised, but the number of times of opening and closing may be counted when the door is lowered. 3A, the open / close counting device 6 is attached to the right end portion of the panel 2. However, the open / close counting device 6 according to the present embodiment has the same components (specifically, an operating lever 60 described later). The second turning element 63 and the turning lever 67 can be simply attached to the left end of the panel 2 using the right and left sides.

The configuration of the open / close counting device 6 will be described. The open / close counting device 6 includes an operation lever 60, a rotation shaft 61 that serves as a rotation support shaft of the operation lever 60, and a first rotation that is externally mounted on the rotation shaft 61 so as to rotate integrally with the rotation shaft 61. The moving element 62, the second rotating element 63 rotatably mounted on the rotating shaft 61 so as to be independent of the rotation of the rotating shaft 61, and the operating lever 60 maintain the normal posture (horizontal posture). The number of times is added to the first spring element 64 for urging the first rotation element 62, the second spring element 65 for suppressing the swing of the second rotation element 63, the counter 66, and the counter 66. And a third spring element 68 that couples the second rotation element 63 and the rotation lever 67 to each other.

These components of the open / close counting device 6 are supported by two support members 8 and 9. As shown in FIG. 9, the support member 8 is formed in a U-shape in a side view from a rising side 80, a lower side 81, and an upper side 82, and the supporting member 9 has a rising side 90 and a lower side 91. Is formed in an L shape in side view. The support member 8 and the support member 9 are fixed with screws by overlapping the portions of the lower sides 81 and 91 so that the side sides 80 and 90 face each other with a space therebetween. In the embodiment, the support member is formed from two members, but the support member may be integrally formed from one member.

The side sides 80 and 90 are formed with receiving holes 800 and 900 that are positioned at the same height and rotatably support the rotation shaft 61, and the rotation shaft rotates horizontally between the side sides 80 and 90. Supported as possible. In the space between the side edges 80 and 90, the first rotation element 62, the first spring element 64, the second rotation element 63, and the like are arranged on the rotation shaft 61 from the side edge 80 toward the side edge 90. A second spring element 65 is packaged. A counter 66 is provided on the upper side 82 of the first support member 8 (see FIG. 4).

The side 90 of the support member 9 has a height greater than that of the side 80 of the support member 8, and a part of the upper half of the side 90 of the support member 9 is cut out and bent toward the support member 8. Thus, a horizontal locking piece 92 is formed. Further, a horizontal locking piece 93 is formed by cutting out a part of the lower part of the side 90 of the support member 9 and bending it to the support member 8 side.

The support members 8 and 9 and the individual components (excluding the operation lever 60) are housed in a box-shaped casing 6A. A part of the support members 8 and 9 may constitute a part of the casing. Below, each component is demonstrated in detail.

The operating lever 60 is a needle-like elongated member, and a base end portion is fixed to one end of the rotating shaft 61, and the operating lever 60 and the rotating shaft 61 are rotated together. The operating lever 60 is maintained in a horizontal posture (normal posture) during normal times when no external force is applied. The actuating lever 60 is rotatable in a first direction (downward) and a second direction (upward) with respect to the horizontal posture.

The rotating shaft 61 is a cylindrical member having a circular shape in cross section, and a fitting portion 610 having a hexagonal shape in cross section is formed at an intermediate portion in the length direction of the rotating shaft 61 (FIG. 8E). ). Therefore, as for the cross-sectional shape of the rotation shaft 61, in the length direction, the intermediate part is hexagonal and the both side parts are circular.

As shown in FIG. 8A, the first rotation element 62 includes a substantially rectangular plate-like main body 620 extending in a direction orthogonal to the rotation shaft 61, and a main body 620 from a substantially central portion of the main body 620. On the same side as the second cylindrical portion 622 from the main body 620, the long first cylindrical portion 621 and the short second cylindrical portion 622 extending in opposite directions to each other in the vertical direction (the direction in which the rotation shaft 61 extends). And three projecting portions 623, 624, and 625 that project. The protrusion 623 is located above the second cylindrical portion 622 and protrudes from the center of the upper side of the main body 620. The protrusions 624 and 625 are lower corners (both ends of the lower side) of the main body 620. Projected to be located in each. In the illustrated embodiment, the projecting dimensions from the main body 620 are the projecting portions 624 and 625> the projecting portion 623> the short second tubular portion 622. Typically, the first rotating element 62 is made of resin.

The internal spaces of the first cylindrical portion 621 and the second cylindrical portion 622 communicate with each other, and the cross-sectional shape of the internal space is a hexagonal shape. The first cylindrical portion 621 and the second cylindrical portion 622 are connected to each other. When the fitting portion 610 of the penetrating rotation shaft 61 is fitted to the inner surfaces of the first cylindrical portion 621 and the second cylindrical portion 622, the rotation shaft 61 and the first rotation element 62 rotate integrally. It is like that. As shown in FIG. 4, one end side of the fitting portion 610 of the rotating shaft 61 is in close proximity to or in contact with the inner wall of the side 80 (the peripheral wall of the receiving hole 800), and the other end side (operation) of the rotating shaft 61. The side opposite to the side on which the lever 60 is fixed is close to or in contact with the inner wall of the side 90 (the peripheral wall of the receiving hole 900). By doing in this way, the movement of the rotation shaft 61 in the length direction is restricted. The structure for integrally rotating the rotation shaft 61 and the first rotation element 62 is not limited to a configuration in which the cross sections are formed in a polygonal shape and fitted as in the embodiment. The first rotating element 62 may be fixed to the rotating shaft 61 by a wearing member.

As shown in FIG. 8C, the second rotating element 63 protrudes on both sides of the main body 630 on one end side of the long and plate-like main body 630 extending in a direction orthogonal to the rotating shaft 61. A projecting portion 631, a hook portion 632 formed on the upper portion of the other end side of the main body 630, and a short cylinder portion 633 formed on both sides of the main body 630 on the side close to the projecting portion 631. An internal space of the short cylinder portion 633 serves as an insertion hole for the rotation shaft 61. The second rotation element 63 is externally mounted on the rotation shaft 61 so as to be rotatable. That is, the second rotation element 63 is independent of the rotation of the rotation shaft 61, and the rotation of the rotation shaft 61 is not directly transmitted to the second rotation element 63. Typically, the second rotating element 63 is made of resin.

As shown in FIG. 4, the protrusion 624 of the first rotation element 62 is located below the protrusion 631 of the second rotation element 63, and the first rotation element 62 rotates in the first direction. When the protrusion 624 moves up and moves upward, the protrusion 624 contacts and locks the protrusion 631 from below to above, pushes the protrusion 631 up and moves upward, and the second rotating element 63 moves. It rotates on the rotation shaft 61 in the first direction. Since the first rotating element 62 and the second rotating element 63 are made to contact each other by utilizing the thickness (projecting dimension) of the protrusion 624 and the protrusion 631, the protrusion 624, Even if the thickness (projection dimension) of the protrusion 631 changes, the locking of the first rotation element 62 and the second rotation element 63 can be ensured.

The counter 66 counts the number of times 1 when the rotation lever 67 is rotated by a predetermined angle or more in the first direction (downward), and when the rotation lever 67 is rotated in the second direction (upward). The number of times is not counted. Thus, the counter itself that performs counting only when the rotating lever rotates in one direction is well known. When the actuating lever 60 rotates in the first direction, the rotation shaft 61 and the first rotation element 62 rotate in the first direction, and the first rotation element 62 rotates in the first direction. The second rotation element 63 that is locked (by the protrusion 624 coming into contact with the protrusion 631) also rotates in the first direction, and the rotation lever 67 rotates in the first direction (downward). The number of times is counted. When the actuating lever 60 rotates in the second direction, the rotation shaft 61 and the first rotation element 62 rotate in the second direction, but the first rotation element 62 rotates in the second direction. Since the (projection 624) is displaced in a direction away from the second rotation element 63 (projection 631), the rotation of the operating lever 60 is not transmitted to the second rotation element 62 and the rotation lever 67. The number of times is not counted.

As shown in FIG. 8B, the first spring element 64 includes a coil portion 640 formed by winding a linear member, and a foot portion 641 composed of both ends of the linear member forming the coil portion 640, Consists of. The first spring element 64 is in a state where the coil portion 640 is sheathed on the second cylindrical portion 622 of the first rotation element 62, and the two legs 641 are disposed on both sides of the protrusion 623 of the first rotation element 62. It passes through and is located on both sides of the locking piece 92. A washer 64A is externally fitted between the coil portion 640 of the first spring element 64 and one short cylinder portion 633 of the second rotating element 63 (FIG. 4).

When the operation lever 60 is rotated from the horizontal posture (normal posture) in the first direction or the second direction, the rotation shaft 61 and the first rotation element 62 are moved in the first direction or the second direction. At this time, a force in the direction opposite to the rotation direction is accumulated in the first spring element 64. Therefore, when the operating lever 60 rotated in the first direction or the second direction becomes free, the operating lever 60 returns to the horizontal posture (normal posture) by the urging force of the first spring element 64. ing. Since the minute rotation of the operating lever 60 (first rotation element 62) is absorbed by the first spring element 64, the minute rotation is not transmitted to the rotation lever 67 and erroneously counted. Even when the operating lever 60 (first rotating element 62) is rotated largely, the operating lever 60 (first rotating element 62) is quickly returned to the normal posture by the first spring element 64, and thus erroneously counts. (Eg double counting) is prevented.

As shown in FIG. 8D, the second spring element 65 includes a coil portion 650 formed by winding a linear member, and a foot portion 651 composed of both ends of the linear member forming the coil portion 650, Consists of. The second spring element 65 is a state in which the coil portion 650 is sheathed on the other cylindrical portion 633 of the second rotation element 63, and one of the two legs 651 is a protrusion 631 of the second rotation element 63. The other is locked to the locking piece 93. The second spring element 65 has a function of suppressing the swinging / swinging of the second rotating element 63. Therefore, even if an acceleration that rotates the second rotating element 63 acts on the second rotating element 63, the second spring element 65 absorbs this acceleration, and therefore the second rotating element 65 is the door body. The counter 66 is prevented from erroneously counting the number of times by operating the acceleration lever and its own weight to rotate the rotation lever 67.

In the open / close counting device 6 for the overhead door configured as described above, when opening the opening by raising the door body in the fully closed position, the open / close counting device 6 provided on the second-stage panel 2 from below is As the panel 2 rises, the operating lever 60 that extends horizontally contacts the lower guide portion 70 of the contacted body 7 provided on the guide rail 1 and rotates slightly downward (first direction). When the leading end of the operating lever 60 that is guided to the locking portion 72 in the posture and rises together with the panel 2 is locked to the locking portion 72, the operating lever 60 is largely rotated in the first direction (downward). At this time, due to the rotation of the operating lever 60, the rotation shaft 61 and the first rotation element 62 rotate in the first direction and engage with the first rotation element 62 that rotates in the first direction ( The second rotating element 63 that is formed by the protrusion 624 coming into contact with the protrusion 631 also rotates in the first direction, and the rotation lever 67 rotates in the first direction (downward) by a predetermined angle. The number of times is counted. When the operation lever 60 is further lifted together with the panel 2, the engagement between the distal end of the operation lever 60 and the engaging portion 72 is released, and the operation lever 60 rotated in the first direction is applied by the biasing force of the first spring element 64. Returning to the horizontal posture (normal posture) while following the upper guide portion 71. Thus, every time the door in the fully closed position is opened, a counting operation is performed to increase the count number by one.

When the door 60 in the fully open position is lowered and the opening is closed, when the operating lever 60 that descends with the lowering of the panel 2 comes to the height position of the contacted body 7, the tip of the operating lever 60 becomes the upper guide portion 71. The actuating lever 60, which is guided downward in a posture rotated slightly upward (second direction) in contact with the second lever and rotated in the second direction, causes the lower guide portion 70 to be moved by the biasing force of the first spring element 64. Return to the horizontal posture (normal posture) while copying.

The present invention can be used as an overhead door open / close counting device.
