Description

Description: TECHNICAL FIELD The present invention relates to a device for automatically opening and closing a door of a Buddhist altar, and more specifically, a pair of left and right door bodies attached to a box body of the altar The door can be opened and closed easily and smoothly by driving the link through two sets of links connected to the slide plate provided on the door, and it can be fitted into the sliding portion. A door opening / closing device for a Buddhist altar, which is capable of performing a series of opening / closing operations at a constant speed by eliminating the breathing phenomenon of the door body that occurs during the opening / closing of the door body by linking the friction applying means to the slide plate. .

(Prior Art) Conventionally, a device that automatically opens and closes the door of a Buddhist altar has been
-It is known by No.44925.

In this structure, a pair of folding door-shaped doors are hinged to the front opening of a kitchen in a Buddhist altar, and a driving device for opening and closing the doors is a two-rail member having a slide piece and an endless member connected to the slide piece. It is composed of a connecting cord and an electric motor of a rotating body linked with the endless connecting cord, and the door body is opened and closed by supplying power to the electric motor.

(Problems to be Solved by the Invention) The above-mentioned Buddhist altar door opening / closing device has a large number of components and complicated linkages, so that the entire device becomes large-scale and the manufacturing cost rises. Since the range of lateral movement of the member that opens and closes the door is large, and the slides and guides are extended horizontally, the horizontal width of the Buddhist altar where these devices are installed becomes unnecessarily large and cannot be used in a small room. There are only a limited number of places.

The slide piece of the arm to which the door is attached always engages with the rail member and moves while rubbing against it, so that the slide piece does not receive uniform sliding resistance from the opening / closing movement start end to the movement end. The speed of the door changes during the movement of the door, or it stops continuously (breathing phenomenon), and the door does not open and close uniformly and smoothly at a constant speed. The commercial value is extremely low as an automatic opening / closing device.

Further, if the opening and closing angles of these door bodies are slightly misaligned due to the extension of the endless string, the opening and closing of the left and right door bodies becomes unbalanced, resulting in poor appearance.

There are many failures due to the endless string being broken.

(Operation) The opening / closing device for the door of the Buddhist altar of the present invention configured as described above has the following effects.

As shown in Figs. 2 and 3, the pivot (drive shaft) of the outer door link
A case in which the driving means is linked to will be described.

A pair of left and right door bodies are attached to the front side of the Buddhist altar or the opening at the front of the kitchen by a pivot or hinge (the door is attached by the pivot in the explanation of this action) so that it can be opened and closed from the center. Both sides are opened to the left and right.

Therefore, when the opening is closed by the pair of doors, the slide plate in the sliding portion provided on the upper or lower end of the outer door is positioned on the rotating shaft side as shown by the solid line in FIG. When the drive means is operated in the forward direction, the outer door link fixed to the drive shaft rotates outward from the box body, as indicated by the solid line arrow in FIG. Since the outer door is pushed outward through the slide plate, the entire door body starts to open from the opening of the box body around the rotation axis of the base as shown by the dotted line in the figure.

Then, the slide plate gradually moves in the opposite direction from the inner door side, that is, the position described above, inside the sliding portion and pushes the inner door link pivotally supported by this slide plate, so that the inner door connected to this link is The inner door is gradually rotated inward (the opening angle of the inner door is gradually returned) with the rotation of the outer door about the hinge, and as shown by the dotted line in FIG. The state is maintained while being corrected to the parallel state.

Further, when the driving means is operated to rotate the outer door link, the pair of door bodies move from the position shown by the dotted line in the figure while the slide plate connecting the link and the inner door link slides in the sliding portion. The opening operation is performed smoothly and continuously at a constant speed without passing through the position indicated by the one-dot chain line to the position indicated by the two-dot chain line.

Further, when the drive means is operated in the reverse direction in the open state of the door body, that is, in the position shown by the chain double-dashed line in FIG. 3, the outer door link fixed to the drive shaft is indicated by the double-dashed chain line arrow in FIG. As shown in the figure, it rotates inward of the box body and pulls the outer door inward through the slide plate, so that the entire door body moves to the position shown by the two-dot chain line and one-dot chain line in the figure, It begins to close toward the opening of the box centering on the rotation axis of its base.

Then, the slide plate is gradually moved in the opposite direction from the position on the inner door side, that is, the rotation shaft side in the sliding portion, and pushes the inner door link pivotally supported by the slide plate, so that the slide plate is connected thereto. The inner door is gradually rotated inwardly around the hinge (the opening of the inner door is gradually returned) along with the rotation of the outer door, and as shown by the dotted line in FIG. The state is maintained while being corrected to be parallel to the opening surface.

Further, when the driving means is operated to rotate the outer door link, the pair of door bodies are moved to the position shown by the dotted line in the figure while the slide plate connecting the link and the inner door link slides in the sliding portion. Therefore, while keeping the inner door parallel to the opening, the closing operation of the opening in the box is performed smoothly and continuously at a constant speed without stagnation up to the position indicated by the solid line.

Next, as shown in FIG. 5, the case where the drive means is linked to the rotary shafts of the pair of door bodies will be described.

The basic operation is the same as when the drive means is linked to the above-mentioned pivot.

When the drive means is rotated in the forward direction when the opening is closed by the pair of doors, the rotation axis of the door is rotated to rotate the outer door outward.

Then, by this operation, the outer door link pivotally attached to the top plate or the bottom plate at the base pivots outward, and the slide plate inserted into the sliding portion provided at the upper or lower end of the outer door is Gradually the inside of the sliding part is moved in the opposite direction from the position on the inner door side, that is, the rotation shaft side, and the inner door link pivotally supported by this slide plate is pushed, so the inner door connected to this slides the butterfly plate. The inner door is gradually rotated inward as the outer door rotates (the opening of the inner door is gradually returned), and the inner door is parallel to the opening surface as indicated by the dotted line in the figure. The state is maintained while being corrected to.

Further, when the driving means is operated to rotate the rotation shaft, the slide plate connecting the outer door link and the inner door link slides in the sliding portion with the rotation of the outer door link, and the pair of door bodies is moved. The open operation is smoothly and continuously performed up to the full open limit.

Further, when the drive means is operated in the reverse direction with the door body opened, the door body fixed to the rotating shaft rotates inward, and the outer door link rotates in accordance with the rotation of the outer door link. While the slide plate connecting the inner door links slides in the sliding portion, the door body starts to close toward the opening of the box body around the rotation axis.

Then, the slide plate is gradually moved in the opposite direction from the position on the inner door side, that is, the rotation shaft side in the sliding portion, and pushes the inner door link pivotally supported by the slide plate, so that the slide plate is connected thereto. The inner door is gradually rotated inwardly around the hinge (the opening of the inner door is gradually returned) along with the rotation of the outer door, and as shown by the dotted line in FIG. The state is maintained while being corrected to be parallel to the opening surface.

Further, when the drive means is operated to rotate at the time of rotation, the pair of door bodies are moved while the slide plate connecting the outer door link and the inner door link slides in the sliding portion as the outer door link rotates. While keeping the inner door parallel to the opening, the closing operation of the opening in the box is performed smoothly and continuously at a constant speed without stagnation.

Thus, the door body of the Buddhist altar can be opened and closed easily and simply by rotating the drive shaft or the rotating shaft in the forward and reverse directions by the drive means.

Further, since a constant braking force is applied to the slide plate that moves in accordance with the rotation of the outer door link by the friction imparting means linked to the slide plate in the sliding portion, it is possible to rotate each link and the rotation portion. Even if dynamic play or play occurs, the friction applying means absorbs the rotary play or play, and the moving speed of the door body changes during the rotation of the door body, or
The door body operates smoothly without opening or closing, and opens and closes.
