Characterized in that the door seat recovery space is formed through.

Hereinafter, a preferred embodiment of the speed door capable of automatic restoration of the present invention will be described in detail with reference to the accompanying drawings.

In the speed door of the present invention, when an external force acts when the door seat descends to close, and the door seat side end is separated from the rail part by the external force, the door seat immediately stops opening and closing, and subsequently opens for the first time. The main point is to implement an operation structure that moves up and down to the closed position and then lowers to the closed position again.

In addition, the speed door of the present invention implements a safety mode that prevents injury to a person and damage to the door seat due to deformation of the elastic bar even when the door seat touches a person or article by binding an elastic bar to the door seat. There is another feature at one point.

To this end, as a main configuration of the present invention, the door seat (made of translucent or transparent vinyl or plastic material, having a property that is easily folded by an external force) is equipped with an elastic bar, the door seat wound portion is stored in the door seat is wound Install the recovery guide.

1 and 2 are attached to the elastic bar is inserted into the transverse direction in the door seat of the speed door capable of automatic restoration according to the present invention.

Referring to FIG. 1, the elastic bar 12, which is restorable in the original position to the door seat 10 of the speed door, has a circular rod shape as a whole, a spring 14 having a predetermined length, and both ends of the spring 14. The end is composed of a short support 16 that is integrally connected.

In particular, the sensor 18 is built in the end of the support 16, the kind of the sensor 18 is a lifting path of the door seat 10 as can be seen in the accompanying Figures 3a and 3b It should be selected with the sensing plate 22 mounted on the inner wall surface of the rail portion 20.

Basically, since the inside of the rail unit 20 may be easily contaminated with various kinds of contamination, including dust and oil, when the sensing plate 22 is installed with magnetic tape, the sensor may be adopted as a magnetic field sensor. If the plate 22 is installed with iron tape, the sensor 18 may be adopted as a gap sensor, and any sensor capable of detecting each other within a predetermined interval may be adopted.

However, the optical sensor is not preferable in consideration of contamination, and it is also possible to use a sensor that is not accurate because it may operate within a certain range.

In addition, on the support 16 at the position inwardly from the attachment position of the sensor 18 is mounted a roller 26 in contact with the cloud along the guide 24 mounted to the rail portion 20, in particular On the support 16 at the position between the roller 26 and the sensor 18 is further attached a leaf spring 28 in the form of an obtuse angle.

In this case, as shown in FIG. 1, two and three connecting rods 30 (hard rods that are not deformed) may be connected between the springs 14 of the elastic bars 12 to further reduce the degree of deformation of the elastic bars.

In another embodiment, it is possible to apply all of the elastically deformable bars instead of the spring applied to the in-situ resilient elastic bar 12, as shown in Figure 2 of the thin thickness is connected between the support 16 It can be applied to the spring steel plate 32, the groove 34 is formed along the longitudinal direction of the spring steel plate 32 can adjust the degree of elasticity.

The elastic bar 12 of such a structure is integrally mounted to the door seat 10 along the horizontal direction, and a plurality of the elastic bars 12 are integrally formed at equal intervals along the vertical direction.

As described above, according to the present invention, unlike the conventional bar of a rigid rod type that is not deformed at all, as the binding / applying the elastic bar 12 that can be restored to the original position in the door seat 10, a person or an object may be touched. In this case, while the elastic bar 12 and the door seat 10 are deformed, the shock can be absorbed to provide safety, and as will be described later, the door seat can be immediately restored to completely eliminate the breakage of the door. do.

Here, the structure of the recovery guide of the main configuration according to the present invention will be described.

As shown in FIG. 6 and FIG. 7, the recovery guides 36 are installed in the door sheet winding unit 38 in which the door seat 10 is wound and stored so as to be opened and closed in front and rear directions, respectively.

In more detail, an upper end of each of the recovery guides 36 is mounted to each of the front end and the rear end of the inlet part of the door seat winding part 38 by hinge pins, and the hinge pins open and close the driving guide 36. The solenoid or stationary motor 40 is connected by means.

In particular, the front end of the upper end of the rail portion 20 and the front end of the inlet portion of the door seat winding portion 28, and the rear end of the upper end of the rail portion 20 and the door seat winding portion 28 Between the rear end of the inlet portion, the door seat 10, which is separated as described below, is penetrated into the door seat recovery space 42 for restoring to the original normal track.

At this time, the recovery guide 36 is closing the door seat recovery space 42, the operation of opening the door seat recovery space 42 during the return movement (opening operation) of the door seat 10.

On the other hand, the drive means of the door seat winding unit 38 and the forward and reverse motor which is the drive means of the recovery guide 36, and the sensing plate 22 of the sensor 18 can exchange electrical signals with the control unit (not shown) Is connected.

Here, looking at the operating state of the speed door capable of automatic restoration of the present invention made as described above are as follows.

The door seat 10 of the speed door is configured to move up and down along the rail 20 in a state of being stored in the door seat reel 38 (for example, a drum), and the speed door shown in FIG. Ascending and descending is repeated by repeating the closed or fully open state shown in FIG.

Normal opening / closing operation (see attached FIGS. 5A and 5B) in which the door seat 10 of the speed door is automatically opened and closed is automatically performed by sensing and controlling operation by an entrance object detection sensor. As the same known facts, the description is omitted here.

If the door seat 10 is subjected to an external force (wind power, interference with an occupant or an object, etc.) of a predetermined size or more while the door seat 10 of the speed door is normally opened or closed, the door seat ( 10 immediately stops the opening and closing operation and rewinds to the door seat winding unit 38 to perform the opening operation.

That is, as shown in FIG. 6, the elastic bar 12 is deformed when the person touches the lower end of the door seat 10 or when an external force of a predetermined size or more is applied to the front or rear surface of the door seat 10. Departure from the guide of the rail unit 20, the door seat 10 is rewinded to the door seat wound portion 38 to perform the opening operation.

At this time, when the external force is applied to the lower end, front or back of the door seat 10, the elastic bar 12 bound to the door seat 10 is deformed and restored back to the original position. In the case of a person, the elastic bar 12 absorbs the shock to provide safety to the person.

Here, with reference to Figures 6 to 8 attached to the process of performing the immediately opening and closing operation immediately after the external force is applied to the door seat 10, the opening operation is as follows.

When an external force is applied to the door seat 10, the elastic bar 12 is deformed, and as shown in FIG. 4, the rollers 26 mounted at both ends of the elastic bar 12 are provided. It is separated from the guide 24 of the rail part 20.

More specifically, the obtuse angled leaf spring 28 is compressed while being pushed out through the limited space of the guide 24 and at the same time the roller 26 mounted at both ends of the elastic bar 12 It is separated from the guide 24 of the rail part 20.

At this time, when the external force applied to the door seat 10 is large, the leaf spring 28 is completely compressed and the elastic bar 12 itself is completely separated from the guide 24, and the door seat 10 is applied to the door seat 10. When the external force is small, the elastic bar 12 enters the rail part 10 again by the restoring force of the leaf spring 28.

At the same time, when both ends of the elastic bar 12 are separated from the guide 24, the sensor 18 attached to the support 16 of the elastic bar 12 is on the wall of the rail part 20 on the opposite side. The sensor plate 22 is separated from the sensing plate 22, and a signal indicating that the elastic bar is separated from the guide of the rail unit is transmitted to the controller.

Subsequently, the control unit sends an instantaneous stop signal to the forward / reverse motor, which is the end of the door seat winding unit 28 and the recovery guide 36, and immediately sends a driving signal for reverse rotation. 36 also performs the opening operation, the door seat 10 is rewinded by the door seat winding unit 28 to perform the opening operation.

Particularly, if the elastic bar 12 itself is completely separated from the guide 24 of the rail part 20 (the door seat is completely separated), the door seat 10 may be formed by the door seat winding part 38. The front end of the upper end of the rail seat 20 and the front end of the inlet of the door seat wound part 38 are opened according to the opening operation of the recovery guide 36 with the rewinding operation. The door seat 10 separated through the space between the parts or the space between the rear end of the upper end of the rail part 20 and the rear end of the inlet part of the door seat winding part 38 is rearward to the door seat winding part 38. It is cold.

Next, when the door seat 10 is rewound by the door seat winding unit 38 as described above, and the door seat is completely opened, the control unit is connected to the stationary motor 40 which is the driving means of the door seat winding unit and the recovery guide. The forward rotation signal is transmitted.

Accordingly, the recovery guide 36 is in a closed state, and the closing operation of lowering the door seat 10 while the door seat 10 is released from the door seat winding unit 38 is performed.

At this time, the rollers 26 at both ends of the elastic bar 12 bound to the door seat 10 reenter the guide 24 of the rail part 20 which is the original normal track, and the leaf spring 28 In addition, re-entry into the rail portion 20, the door seat 10 is to perform a normal lowering operation for closing along the guide 24 of the rail portion 20.

As described above, when the external force acts on the door seat 10, the door seat 10 performs the opening operation while absorbing the shock from the elastic bar 12, and then immediately closes the door. The breakage of the sheet 10 can be easily prevented.

In particular, when the external force applied to the door seat 10 is large, and the elastic bar 12 is completely detached from the rail unit 20, the door seat 10 may be wound around the door seat 10 through the recovery guide 36. It can be rolled back to and then return to normal to the track of the rail portion 20 immediately.

As a result, when the door seat 10 is closed or may be damaged by an external force during the opening operation, even if an external force is generated in the door seat 10 in any direction, the roller 26 may be deformed by the deformation of the elastic bar 12. The portion is separated from the guide 24, and subsequently the return movement of the door seat 10 can be made.

On the other hand, the obtuse angle leaf spring 28 attached to both ends of the elastic bar 12 has a small external force acting on the door seat 10 when the speed door is installed indoors (such as a person or an object). It does not need to be used).

On the other hand, when the door seat 10 is installed on the outside, the basic load, such as wind is largely applied, in this case the obtuse leaf spring 28 serves to supplement the elasticity of the elastic bar 12 In addition, in addition to the basic external force, if a large force that can cause damage to the speed door, such as a person, vehicle, object is applied to the leaf spring 28 to prevent the breakage of the door.

As seen above, the speed door capable of automatic restoration according to the present invention provides the following effects.

1) When an external force is applied to the door seat of the speed door, the shock can be absorbed by the elastic bar to easily prevent damage to the door seat.

2) If the person is a person, the elastic bar of the door seat can be bent and deformed to absorb the impact and provide safety to the person.

3) When the door seat is partially detached from the rail part together with the deformation of the elastic bar, the door seat may be retracted by the door seat reel to immediately open the door seat to further prevent damage to the door seat.

4) Even if the door seat is completely separated from the rail part due to the large external force, the door seat is rewound to the door seat winding part through the recovery guide, and then immediately returns to the rail part which is the original lifting track. There is this.
