Description

[Detailed description of the invention] The present invention relates to a component mounting device for an automatic door opening/closing device in which the component parts of an automatic door opening/closing device are attached without any problem, and in particular, one end of the component is completely fixed in a locking groove. The present invention relates to a mounting device for an automatic door opening/closing device that prevents noise and loosening of fasteners caused by vibrations at one end of the component.

As shown in FIG. 1, a conventional mounting device for attaching components of an automatic door opening/closing device without a door has a locking protrusion 4 protruding from the lower surface of the horizontal piece at the upper end of the door 1 or the rear surface of the vertical piece. A locking groove 2 opening in the direction of the locking projection 4 is provided at a position facing the locking projection 4, one end of the component 3 is fitted into the locking groove 2, and the other end of the component 3 is inserted into the locking groove 2. There is one that fixes the locking projection 4 to the locking protrusion 4.

In this case, the locking protrusion 4 and the locking groove 2 are formed over the entire length of the mesh in the longitudinal direction.

This is to enable the structural component 3 to be attached to any position in the longitudinal direction of the blind 1.

The locking groove 2 in this mounting device is such that the gap between the grooves is larger than the thickness of one end of the component to be fitted.

In this case, one end of the component 3 is only prevented from coming off to the outside of the locking groove 2, but is not fixed at this part, and the mounting strength is determined by the locking protrusion 4 at the other end of the component 3. depends on the fixation of

Therefore, since there is play between one end of the component 3 and the locking groove 2, if vibration occurs in the component 3, noise may be generated from this part, or the vibration may cause the other end of the component 3 to lock. There is a drawback that the fixation to the stopper projection 4 may become loose.

The purpose of the present invention is to eliminate the drawbacks of the above-mentioned prior art and to provide a component mounting device for an automatic door opening/closing device that prevents noise and loosening of fasteners caused by vibrations at one end of the component. shall be.

The present invention will be explained below with reference to FIG.

The mesh 1 is formed by extrusion molding aluminum material, etc.: The locking groove 2 is recessed in the lower end horizontal piece of the mesh 1 over the entire length in the longitudinal direction of the mesh 1. It is formed integrally with Mume 1.

The locking groove 2 has a parallel side 21 on one vertical side of the blind 1, which is formed substantially parallel to the blind vertical piece. An open vertical one-sided oblique side 22 extends obliquely forward and downward from the lower end of this open vertical one-sided parallel side 21, and an open vertical one-sided oblique side 22 extends rearward and obliquely downward from the tip of this open vertical one-sided oblique side 22, and its tip is blank. Eye vertical side parallel side 2
1, an open horizontal one-sided oblique side 23 that extends upward from the tip of this open horizontal one-sided oblique side 23 substantially parallel to the open vertical one-sided parallel side 21, and whose tip ends as an open vertical one-sided parallel side. 21
It is formed from four sides including vertical sides 24 on one side of the vertical side without openings, which are located below the lower end of .

Then, the distance perpendicular to the sides, that is, the gap in the upward direction, between the parallel side 21 in the vertical direction and the vertical side 24 in the horizontal direction is defined as A,
If the vertical distance between the vertical one-sided oblique side 22 and the vertical side 24 on the vertical side 24 is vertical to the vertical one-sided oblique side 22, that is, the gap in the diagonally downward direction is B, then the distance between the two is B. ＞Determine its size so that A.

Then, as shown in FIG. 3, the thickness of one end of the component 3 is C.
Then, set C so that B>C>A.

The locking protrusions 4 are provided on the horizontal piece of the upper end of the blind 1 so as to protrude from each other along the entire length of the blind 1 in the longitudinal direction, and are formed integrally with the blind 1. 5 to fix one end of the component 3.

The position of the locking projection 4 on the upper horizontal piece of the blind 1 is such that the lower surface of the side plate having the through hole of the special nut 5 clamped by the locking projection 4 is locked at a horizontal distance from the vertical piece of the blind 1. It is made to be equal to the parallel side 21 of the vertical side of the groove 2, or to be on the vertical side of the vertical side of the groove 1 from the parallel side 21 of the vertical side of the groove 2.

This is so that when the other end of the component 3 is fixed to the locking protrusion 4 via the special nut 5, one end of the component 3 is completely fixed to the locking groove 2.

Next, a method for attaching the component 3 to the blind 1 using the attaching device according to the present invention will be explained based on FIG.

Insert one end of the component 3 into the locking groove 2 diagonally downward from the rear of the eyelet 1, and insert the other end of the component 3 into the eyelet 1 at a desired arbitrary position in the longitudinal direction of the eyelet 1. Raise it forward.

Connect the other end of the component 3 to the locking protrusion 4 through the special nut 5.
When the component 3 is not fixed, the upper gap A of the locking groove 2 is slightly smaller than the thickness C of one end of the component.
is not perpendicular to the lower end horizontal piece of the mesh 1, and component 3
One end of the locking groove 2 is not in complete contact with the parallel vertical side 21 of the locking groove 2.

Furthermore, the other end of the component 3 is raised against the pressure of the parallel vertical side 21 of the locking groove 2, and is fixed to the locking protrusion 4 with the bolt 6 via the special nut 5. The thickness C at one end is larger than the upward gap A, so the locking groove 2
Pressure is applied to the parallel sides 21 on one side of the vertical side without openings and the vertical sides 24 on one side of the vertical side without openings, these sides completely contact one end of the component 3, and the restoring force of the parallel sides 21 on the vertical side without openings causes the component 3 to One end can be completely fixed in the locking groove 2.

Although the other end of the component 3 is fixed to the locking protrusion 4 using a special nut 5, it goes without saying that other methods that do not use the special nut 5 may be used.

As explained above, the present invention provides a locking groove with a special shape and completely fixes the component in the locking groove, thereby preventing vibrations from the component mounting device. can.
