The door shoe 110 attached to the lower portion of the door 100 is moved to the rail grooves 122 of the rail frame 120 provided on the floor surface by a shock or pressure externally applied to the known elevator door 100, In order to prevent it from being detached from the main body (1). The door shoe 110 includes a mounting bracket 112 mounted on the lower frame of the door and a guide shoe 114 formed on the mounting bracket 112 and slid on the rail groove 122.

The present invention prevents the door shoe mounted on the lower portion of the door from being detached from the rail groove of the rail frame against impact or pressure externally applied to the elevator door, So that the departure-avoidance function can be easily performed.

The escape prevention device 1 according to the present invention includes an escape prevention hole 10 formed on one side of a rail groove 122 through a conventional perforation process; A mounting hole 20 formed to penetrate the mounting bracket 112 of the door shoe 110 at a position corresponding to the escape prevention hole 10; And when the door 100 is positioned on the release hole 10, the door 100 is inflated and prevented from being released while being elastically deformed. When the door 100 is opened, And a locking means (30) which is retracted while being disengaged from the departure prevention hole (10). At least one or more of the departure prevention holes, the mounting hole, and the locking means may be formed at positions corresponding to each other.

The mounting bracket 112 of the door shoe 100 is made to have a size that allows the mounting hole 20 to be formed at a size larger than a conventional size to form the mounting hole 20. [ That is, the guide shoe 114 is formed to extend to both sides of the guide shoe 114 formed on the mounting bracket 112, and is manufactured to have a size capable of forming the mounting hole 20.

The locking means 30 includes a housing 32 fixed on the mounting hole 20 by a conventional welding or bracket or the like so as to be in contact with the side surface of the rail groove 112 at one side of the housing 32, And a locking member 36 which is inserted into and withdrawn from the separation preventing hole 10 by shrinking or expanding the first elastic body 34 provided inside the first elastic body 34 when the first elastic body 34 is positioned at the first position. At this time, the tip end of the locking member 36 where the release preventing hole 10 is located further includes an inclined surface 36a inclined from the rail groove 122 side to the landing side. That is, the inclined surface is inclined from the direction in which the door is opened to the direction in which the door is closed. The first elastic member may be a conventional coil spring or a leaf spring.

The locking member 36 can be selectively formed according to the size of the elevator, such as a conventional plate shape or a bar shape, and it is preferable to select the locking member 36 to have a proper thickness depending on the rail groove.

When the pair of elevator doors are slid and closed, the locking member of the locking means provided on the mounting hole of the mounting bracket of the door shoe is positioned at the position of the escape prevention hole formed in the rail frame, And is inserted into the separation preventing hole while expanding.

Even if an impact or pressure exerted from the outside is generated in the elevator door, the locking member of the locking means inserted from the rail groove of the rail frame together with the mounting bracket of the door shoe into the escape prevention hole formed on one side surface of the rail groove, The lower end is not separated from the rail groove.

Accordingly, the present invention is not limited to a complicated technical structure, but can solve all the problems caused by a foreign matter introduced due to a simple structure, particularly, by providing fixing means in a rail groove as in the prior art.

Further, the present invention is advantageous in that it is originally prevented from being detached by strong shock or pressure by being locked by a locking means on a mounting hole formed in a mounting bracket of a door shoe by a release preventing hole formed on one side surface of a rail groove .

In addition, when the slope formed on the locking member has a minimum contact area when it is in contact with the side surface of the rail groove, sliding can be performed smoothly. When the slope is inserted after the locking member is inserted into the separation prevention hole, As the first elastic body in the housing is contracted, the locking member is inserted into the housing and smoothly separated from the first elastic body. At this time, it is preferable that the end of the inclined surface is formed as a curved surface for further smooth sliding with the side surface of the rail groove.

Further, one side of the inclined surface 36a and one side of the escape prevention hole 10 which abuts one side thereof further include respective curved portions 38 corresponding to each other. This is because, when the locking member is inserted into and withdrawn from the separation preventing hole, the respective curved portions are brought into contact with each other, so that more natural insertion and detachment can be made.

FIG. 4 is a partially enlarged side sectional view for explaining another embodiment of the present invention, and FIG. 5 is a partially enlarged horizontal sectional view according to FIG.

As shown in the drawings, the locking means provided on the mounting bracket of the door shoe can be made more simple, more convenient to install, and more convenient.

The locking means 30 includes a locking rod 30A which is slidably inserted on the mounting hole 20 so as to be able to move into and out of the separation preventing hole 10, And a second elastic body 30B mounted on an end of the rail groove 122 and supported on a side surface of the rail groove 122. [ At this time, it is preferable to apply a conventional leaf spring or the like to the second elastic body.

That is, when the locking rod is on the rail groove, the second elastic body is kept in a contracted state, and when the locking rod is positioned on the escape prevention hole, the expansion of the contracted second elastic body causes the locking rod So that it can be prevented from coming off. Further, when the locking rod is released from the separation preventing hole due to the door being opened, the second elastic body that has been expanded is contracted again.

The locking means, which is another embodiment of the present invention, has a simpler structure than the above-described locking means, and the same principle as the locking means described above is the same as that of the locking means formed on one side of the rail groove.

In addition, the locking rod of the locking means, which is another embodiment of the present invention, is not fixed to the mounting hole of the mounting bracket of the door shoe but is slidable, so that the assembling operation is also inserted and fitted simply and conveniently.

The second elastic body has one end fixed to the end of the locking rod by ordinary welding or bolt, and the portion contacting the side surface of the rail groove at the other end is bent or curved so as to smoothly slide. .

The tip end of the locking rod 30A where the release preventing hole 10 is located may further include an inclined surface 36a inclined toward the landing side from the side of the rail groove 122 and a side surface of the inclined surface 36a, And each of the curved portions 38 has a shape corresponding to one another on one side of the release preventing hole 10 which abuts on the other side.

So that the locking rod can also be easily detached as well as smoothly inserted into the separation preventing cavity like the above-described locking member.

Thus, the locking means composed of the locking rod and the second elastic body, which is another embodiment of the present invention, can be easily applied due to its simple structure, and can be easily replaced in a short period of time It can be achieved.
