[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel lock device for an over-sliding door which feeds and stores a door horizontally or vertically along a wall or a ceiling.

[0002]

2. Description of the Related Art This kind of over-sliding door is
Attention is paid to the ability to open and close quickly and quietly with a single door at the opening, and the fact that the door is stored on the ceiling as it is so that the opening can be used to the maximum extent, so that the dead space is rationally used. As a result, it has been evaluated as having high reliability and high energy saving.

Now, the electric oversliding door device A will be described with reference to the side view of FIG. In the electric over-sliding door device A, a wire 2 for lifting the sliding door 1 is wound around a drum 3, and a shaft 4 of the drum 3 is rotated by a motor 6 via a chain 5, and the sliding door 1 is moved up and down to open and close. ing. In the figure, α is an opening, β is a ceiling, and 7 is a left and right parallel guide rail.

[0004]

However, when the opening α is small, if the sliding door 1 is lifted by several persons, the wire 2 is loosened and the wire 2 is unveiled. . It is an object of the present invention to provide an oversliding door panel lock device that is effective and appropriate to solve the problem.

[0005]

The above object can be attained by the present invention adopting the following novel characteristic constitution means. In other words, the feature of the present invention is that the lower end of a wire wound around a motor-driven drum so as to be able to wind up and down and open and close the sliding door is connected to the upper end of the lock plate, and the upper end of the vertical front groove is inclined upward. A pin slide hole having a continuous groove is formed in the lower portion of the lock plate, and a connection guide pin protruding from the side of the corner holding member attached to each of the left and right ends of the lowermost panel of the sliding door is provided in the pin slide hole. At the lower end of the vertical parallel guide rail fixing frame to which the left and right parallel guide rails for sliding the sliding door are fixed, and the upper end of the lock plate when the sliding door is fully closed. Oversliding with lock plate holders protruding above the level surface A panel locking device of the door.

[0006]

According to the present invention, since the above-mentioned means is taken, when the wire 2 is lifted in tension, the vertical front groove of the pin slide hole is engaged with the connecting guide pin, and the lock plate is substantially vertically upright and locked. When the sliding door 1 is manually lifted when fully closed and the sliding door 1 is lifted manually, the wire 2 is loosened and the connecting guide pin is engaged with the ascending groove of the pin slide hole, so that the lock plate is moved forward. The frontal portion is locked by holding the lock plate, and the sliding door 1 is locked immovable.

[0007]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 and 2 are a side view and a rear view in which a lock plate is lifted by a wire in this embodiment. FIG. 3 is an enlarged side view of the lock plate. FIG. It is a side view in which the plate is locked by the lock plate holder. The same members as those in FIG. 5 are denoted by the same reference numerals.

In the drawing, B is a panel locking device for an oversliding door of the present embodiment, 8 is a connecting hole 9 for binding the lower end of the wire 2 at the upper end, and a vertical front groove 10
a lock plate 11 having a pin slide hole 10 formed at the lower end thereof and a butt-up inclined portion 10b at the upper end of
The front L-shaped bite holding members 1 each bent upward from the lower ends of the side sides 13a of the corner holding members 13 attached to the left and right sides of the lowermost panel 12 of the sliding door 1, respectively.
4 to protrude from the side 13a of the corner holding member 13,
In addition, the connection guide pin 15 movably penetratingly connected to the pin slide hole 10 of the lock plate 8 which is bittenly inserted into the bite holding member 14, protrudes from a rearward middle of the lateral side 13 a of the corner holding member 13 and lock plate. A restricting pin 16 for preventing the falling of the rear end of the rotating shaft 8 is fixed to an outer protruding end of a rotating shaft 18 which is supported by a bearing bracket 17 at the rear side of the corner holding member 13 so as to freely rotate. The rollers 19 that rotate and run along 7 project from the lower end of the vertical parallel guide rail fixing frame 20 on both the left and right sides at predetermined height positions, respectively, and suppress the head of the lock plate 8 that has tilted forward to ascend. It is a lock plate holder that blocks.

The vertical parallel guide rail fixing frame 20
Are vertically fixed to a window frame portion or the like of a wall on which the electric oversliding door device A is installed, and furthermore, fixedly install the left and right parallel guide rails 7 for sliding the sliding door 1 in an actual use form. The sliding door 1 is an arbitrary frame member.
And the vertical parallel guide rail fixing frame 20. Further, the lock plate retainers 19 are protruded from the lower end of the vertical parallel guide rail fixing frame 20 and located above the upper end level surface of the lock plate 8 when the sliding door 1 is fully closed. You.

Since the specification of this embodiment shows such a specific embodiment, when the opening α is opened and closed by driving the motor 6 to move the sliding door 1 up and down, FIGS. As shown in FIG. 2, the wire 2 is strained,
Since the vertical front groove 10a of the pin slide hole 10 is engaged with the connection guide pin 11 and the lock plate 8 is in a substantially upright posture and does not engage with the lock plate retainer 19, the lowermost panel 12 is locked. It can slide freely against the plate holder 19.

However, when the opening α is formed in the sliding door 1
When the lower end of the sliding door 1 is manually lifted in the fully opened state, as shown in FIG. 4, the wire 2 is relaxed, and the ascending groove 10b of the pin slide hole 10 is slidably engaged with the connection guide pin 11. As a result, the lock plate 8 assumes a forward leaning posture, and the frontal portion is locked by the lock plate retainer 19 that has hit the front, so that the sliding door 1 is locked and cannot be lifted and opened.

[0012]

Thus, according to the present invention, when a lock plate having a specially shaped pin slide hole is interposed between a wire and a connecting guide pin, the wire becomes loose when the sliding door is manually lifted. Since the lock plate falls forward and is locked by the lock plate, it exerts the door lock function, and unwillingly to be unable to open it,
It has excellent practicality and usefulness, such as preventing an unintended theft accident and ensuring a secure crime prevention.
