Description

[Detailed Description of the Invention] This invention relates to a connection member attachment mechanism that connects a connection member for transmitting the output of a drive source provided in an automatic door to the door.

Conventionally, a sliding automatic door is provided with a driving wheel 2 and a driven wheel 3 connected to a driving source 1, as shown in FIG.
A driving device is used in which a door 5 connected to the connecting member 4 via a receiving metal fitting 6 is opened and closed in the direction of movement of the connecting member 4. As a mechanism to connect
For example, a device shown in Japanese Utility Model Publication No. 56-2785 has been proposed.

This device has a holding metal fitting placed on the top surface of the door hanging metal fitting fixed to the top of the door, and inserts both ends of the belt, which is a connecting member, into the groove provided in this holding metal fitting from both end openings to almost the center. , the connecting member is fixed by screwing the presser metal fitting onto the door hanging metal fitting.

However, although this device prevents the belt from slipping by making the protrusions provided in the grooves of the presser fittings bite into the belt, the protrusions cannot be made to bite into devices that use iron wire as the connecting member. Therefore, it cannot be applied. In addition, this device fixes the connecting member to the door and connects both ends of the connecting member at a predetermined position (approximately in the center of the presser metal fitting), but the installation work for this device is difficult to do in a narrow installation space. The work is often difficult.

This invention was developed in view of the above-mentioned problems, and it is possible to easily connect the connecting member and the door with simple installation work, regardless of the connecting member such as iron wire or rubber belt. , the purpose is to be able to securely fix the connecting member without shifting,
Its main structure is an automatic door connecting member that alternately spans three or more bolts installed at the top of the door, and then presses and secures them from above with a presser plate to hold the connecting members in place. This is the mounting mechanism.

Next, the present invention will be explained based on an embodiment shown in FIGS. 2 to 4. Three bolts 12 are made to protrude upward from a connecting member holder 11 fixed to the upper part of the door 1, and are fixed in line in the opening/closing direction of the door. Note that the bolts 12 do not need to be provided on a straight line in the opening/closing direction of the door, and may be offset to the left or right with respect to the opening/closing direction of the door. Then, connecting members 13 made of iron wire or the like are alternately strung around the bolts 12 as shown in FIG.
4 is placed on it, and a nut 15 screwed onto the bolt 12 is tightened to fix it. Therefore, the connecting member 13 is held between the presser plate 14 and the connecting member receiving fitting 11.

As described above, this connecting member attachment mechanism
3 to bolts 12 alternately, then nut 1
Since it is fixed by tightening 5, it is securely fixed and will not slip or shift. This mechanism is particularly suitable for those using iron wire as the connecting member. In addition, as shown in FIG.
4 and the connecting member 13 and between the connecting member 13 and the connecting member receiving fitting 11.
6 and 17 are inserted and tightened, the connecting member 13 bites into the contact plates 16 and 17 and is fixed more securely. In addition, three or more bolts should be protruded from the connecting member fittings provided at the top of the door in the front direction of the installation work (for example, toward the front in Fig. 1, that is, to the right in Fig. 4), and the connecting members should be attached to these bolts alternately. It is also possible to clamp the connecting member by holding it down with a presser plate from above. Although the connecting member is installed in a high place, in the above case, the connecting member cannot be stretched. It is even easier to install because it can be done from the front at eye level.

As mentioned above, this invention is configured so that during installation work, the connecting members only need to be alternately passed around the bolts provided on the connecting member holder and then tightened, so that the connecting members are securely fixed. It has the advantage that it can be easily installed, and that it is less likely to be damaged because it does not damage the connecting member.
