Description

[Detailed description of the invention] The present invention relates to a device for automatic doors that stops the door running along the engine base at the fully open position or the closed position. Additionally, the engine base has a function of concealing the inside so that it cannot be viewed directly from the end of the engine base.

Generally, this type of automatic door has wheels c and c running on rails b of an engine base a, as shown in FIGS. 1 and 2.
The door d is suspended from the engine base and is run along the engine base a. Conventionally, in such an automatic door, in order to stop the door d at the fully open position or the closed position, As shown in Figure 1, stop the door d by hitting the end pillar e of the engine base a, or as shown in Figure 2, if there is no pillar to hit, the engine base The door d is stopped by causing the wheels c and c to hit against a stopper f provided separately at the door a.

However, in the latter case, a separate stopper must be provided, which not only has the disadvantage of increasing the number of parts, but also because there is no column e, etc., the connection between the side plate g that covers the terminal of the engine base a and the door d is The interior of the engine base (a) can be seen through the gap between the two, creating an extremely unsightly appearance.

Therefore, conventionally in such cases, the wide side plate g and the narrow side plate g are aligned and used separately for each case of Fig. 1 and Fig. 2, or the wide side plate g is used from the beginning. It is common practice to manufacture only the side plate g and use it in the case shown in Figure 1 by cutting off the bottom side, but this would require a variety of side plates g. , or it may be necessary to cut it out before use, which is not only economically disadvantageous but also time-consuming.

In order to solve these conventional problems, the present invention is capable of meeting the various conditions described above by using side plates of a single width. This will be explained based on one example.

In FIG. 3, 1 is an engine base, 2 is a door that runs along the engine base 1 in the direction of arrow A, and 3 is a side plate fixed to the engine base 1 so as to cover the end of the engine base 1. Here, the vertical width of the side plate 3 is set to such a length that the upper end of the side surface 2a of the upper door 2 does not collide with it, so that a pillar (not shown) or the like can be erected closely to the same side plate 3. In such a case, by using the side plate 3 as it is, the side surface 2a of the door 2 can be configured to hit against the above-mentioned pillar, etc., and the island visit 2 can be stopped.

Furthermore, near the lower edge of this side plate 3, as shown in FIG. A fixing part 5 having a substantially rectangular shape is formed, and a screw hole 7 with an opening 6 formed on the side surface is formed across both ends of the fixing part 5.
is drilled.

Next, 8 is a mounting part 9, an abutting piece 10, and a connecting part 1 of these parts.
This is a stopper consisting of σ, in which the side surface shape of the mounting portion 9 is formed into a substantially U-shape corresponding to the shape of the fixing portion 5 of the rib 4 so that it can be fitted into the fixing portion 5 of the rib 4. A protrusion 11 is formed in the longitudinal direction of the inner surface of the attachment part 9, which engages with the opening side 6 of the fixation part 5 when the attachment part 9 is inserted into the fixation part 5.

Further, when the mounting portion 9 is inserted into the fixing portion 5 of the rib 4, the abutment piece 10 of this stopper 8 comes into contact with the lower side 3a of the side plate 3, and as shown in FIG. The abutment piece 10 is extended from the mounting part 9 so as to be attached to the lower part of the door 2. At this time, the width of the abutment piece 10 is approximately equal to the width of the side plate 3, and its vertical width is the same as that of the door 2. The width is sufficient for the upper end of the side surface 2a to come into contact with it.

Therefore, in order to attach this stopper 8 to the side plate 3, first fit the mounting part 9 into the fixing part 5 of the rib 4 from the state shown in FIG. 4 to the state shown in FIG. A set screw 12 (see FIG. 4) is screwed into the hole T, and the head 13 of the set screw fixes the mounting portion 9 so that it cannot be pulled out.

At this time, the abutting piece 10 comes into contact with the lower edge 3a of the side plate 3 and is extended downward from the lower edge 3a. The island visit 2 can be stopped by hitting the engine, and the inside of the engine base 1 can be hidden by closing the gap between the side plate 3 and the door 2.

In addition, on pillars (not shown) etc. erected closely to the side plate 3,
If you want to stop the island visit 2 by hitting the side 2a of the door 2, do not attach the stopper 8 to the side plate 3.
S may be used as is; in this case, the interior of the engine base 1 cannot be directly viewed from the outside because of the pillars and the like.

Although not shown, a lid is provided on the front of the engine base 1, so that the interior of the engine base 1 cannot be viewed directly from the front.

As explained above, the present invention is a device that stops the door 2 running along the longitudinal direction of the engine base 1 at the fully open position or the closed position, and is located between the lower side of the side plate 3 of the engine base 1 and the upper side of the door 2. In cases where there is a gap between
A rib 4 extending along the width direction of the side plate 3 is provided on the inner surface of the side plate 3 of the engine base 1, and the stopper 8 has a mounting portion 9 that relatively fits with the rib, and a stopper 8 located below the mounting portion 9. It is composed of an abutment piece 10 that can freely abut against the upper door 2, and a connecting part 10' that connects the attachment part 9 and the abutment piece 10. are fitted into each other and fixed with set screws 12, and the abutting piece 10 of the stopper 8 is attached to the side plate 3.
It is characterized in that it is added to the lower side of the door 2 so that the abutment piece 10 and the door 2 can abut against each other, and the connecting part 10' and the fixing part 9 of the stopper 8 are housed inside the side plate 3. According to the invention, not only can the door 2 be stopped at a predetermined position by the abutment piece 10, but also the abutment piece 10 can stop the door 2 at a predetermined position.
Since it also has the function of closing the gap between the side plate 3 and the door 2, it does not require any special parts.
The interior of the engine base 1 can be hidden, and this results in a favorable appearance.

Further, the stopper 8 can be easily attached to the side plate 3 by simply fitting the mounting portion 9 onto the rib 4 and screwing the set screw 12 onto the rib 4, or conversely by removing the set screw 12. It can be easily removed by simply pulling out the mounting part 9 from the rib 4. Therefore, it can be easily removed under various conditions such as when a pillar etc. is erected on the end side of the engine base 1 or when it is not erected. can be easily and quickly dealt with, and also eliminates the need to cut out the side plate 3 or prepare side plates 3 of various sizes, so it can be extremely advantageous in terms of cost and labor.
