The stopper 140 includes a locking projection 151 provided at the protrusion 141 and a locking protrusion 153 provided at the guide groove 143, and the rotary body 120 when the slider 130 moves to the right direction. ) And to limit the position of the slider 130 so that the door 110 is maintained in an extended state.

Meanwhile, the position of the slider 130 may be adjusted stepwise through the stopper 140, which will be described with reference to FIG. 5.

5 is a plan view of a door for explaining an example of the stopper of FIG. 2A according to a preferred embodiment of the present invention.

The stopper 140 shows the stopper 140 that can reduce or increase the horizontal length of the door 110 step by step.

The stopper 140 of FIG. 5A is provided in the plurality of seating grooves 161 provided in the protrusion 141 and the guide grooves 143 to be elastically supported by the seating grooves 161 when the slider 130 is moved left / right. It is composed of an elastic ball 163.

The seating groove 161 is a hemispherical groove, and is formed in plural at least one surface of the protrusion 141 at a predetermined interval, and the elastic ball 163 is an elastic body 167 installed on one surface of the guide groove 143 as shown. ) And the ball 165 supported by the elastic body 167.

The elastic ball 163 is a form in which the elastic body 167 supports the ball 165. When a certain pressure or more occurs in the ball 165, the elastic body 167 is compressed, and when the pressure is released, the elastic body ( 167 is used to restore. That is, when the end of the ball 165 is in contact with the protruding portion 141, the elastic body 167 is squeezed, at this time, the ball 165 is moved up and down by the depth to which the elastic body 167 is pressed to the outside Exposure is minimized. In addition, when the end of the ball 165 is located in the seating groove 161, the ball 165 is elastically seated in the seating groove 161 by the restoring force of the elastic body 167 to fix the position of the slider 130 It is.

Therefore, the user can gradually reduce or increase the position of the slider 130, that is, the horizontal length of the door 110, using the plurality of seating grooves 161.

Meanwhile, FIG. 5B illustrates that the elastic ball 163 is provided at the protrusion 141, and a plurality of seating grooves 161 are formed in the guide groove 143, which is a corresponding surface. As an example, a detailed description of FIG. 5B will be omitted.

16 and 18 are perspective views showing an example of a safety door according to another embodiment of the present invention.

As shown in the figure, the rotor 120 and the slider 130 may selectively install the number of positions between the pair of vertical frames 111-1 and 111-2.

That is, as shown in Figure 16 may be installed at both ends of the vertical frame 111 in the longitudinal direction, respectively, or as shown in Figure 17 may be provided in a plurality between both ends and the longitudinal direction of the vertical frame 111. In addition, the shape of the rotating body 120 and the slider 130 may be the same shape as the length of the vertical frame 111, the combined form is extended vertically rather than the horizontal bar form.

On the other hand, in the case of Figure 16 and 17, as a structure using the vertical frame 111, that is, for the purpose of lightening the door 110, etc., between the vertical frame 111 is produced in a predetermined open form, and opened A thin panel 200 is used to close the closed surface.

That is, the panel 200 is attached to the open front and rear of the door 110, respectively, and two panels 201 and 203 are attached to the front and the rear, respectively. This is for the door 110 to be attached as a slide structure to the rotating body 120 and the slider 130, respectively. That is, referring to the detailed view "D" illustrated in FIG. 15, it can be seen that the panel 200 is attached to the rotor 120 and the slider 130, respectively.

In addition, referring to the panel 200, the panels 201 and 203 are attached to each other in a predetermined overlapping state. The second panel 203 is to be movable to the outside of the first panel 201 attached to the rotating body 120.

Meanwhile, in the case of FIG. 17, since no open area is generated between the vertical frames 111, the panel 200 may be attached selectively according to the intention of the producer and the user. Also, although not illustrated, the door 200 may be attached to the panel 200. The vertical frame 111 for reinforcement of the 110 may be deleted.

Although the present invention has been described in more detail with reference to the embodiments, the present invention is not necessarily limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.
