Fig. 5 is a view showing a cross-sectional view of a safety door having a finger-fingernail preventing means according to an embodiment of the present invention.

3 to 5, a safety door 100 having a finger-jam preventing unit according to an embodiment of the present invention includes a fixed body 110, a movable door 120, and a finger- ). ≪ / RTI >

The fixing body 110 is formed of a pair of vertical structures on both sides of the entrance 1. The lower end of the fixing body 110 is fixed on the lower supporting portion 101 with screws or bolts. The fixed body 110 is formed in the shape of a rectangular plate having a predetermined thickness, and a sliding groove 110a is formed in the fixed body 110 so as to penetrate in the direction of the doorway 1. [ The sliding groove 110a is formed in the shape of a square groove having a width, a height, and a length corresponding to the thickness, height, and length of the moving door 120 so that the moving door 120, which will be described later, do. In addition, a drive cylinder (not shown), for example, a pneumatic cylinder, is provided inside the fixed body 110 to slide and move the movable door 120. The stationary main body 110 is provided with a drive storage portion 111 for accommodating a rotation drive portion 131 to be described later on the front end of the entrance 1 side. A slit 111a is communicated with the drive receiving portion 111 in the vertical direction by a height of the protective cover 135 so that a protective cover 135 to be described later can pass through the tip of the fixed body 110 .

The sliding door 120 is slidably installed laterally in the sliding groove 110a of the fixed body 110 to open and close the door 1. [ The movable door 120 is slidably connected to a cylinder rod (not shown) of a driving cylinder provided in the fixed body 110. The movable door 120 is formed in the shape of a rectangular plate so that it can be inserted into the sliding groove 110a of the fixed body 110. The transparent window 121 may be installed on the front surface of the movable door 120 so that the movable door 120 can be seen through the opposite side of the movable door 120 even when the movable door 120 is closed. The lower end of the movable door 120 is slidable along a guide rail (not shown) provided on the lower support portion 101. For this purpose, a guide groove (not shown) is formed in the bottom surface of the movable door 120 in the longitudinal direction of the door, and correspondingly, a guide rail (not shown) is formed in the lower support portion 101, So that the mobile door 120 can stably perform opening and closing operations. Alternatively, a guide protrusion (not shown) is formed in the bottom surface of the movable door 120 in the longitudinal direction of the door, and correspondingly, a guide groove (not shown) is formed in the lower support part 101, The movable door 120 can be stably opened and closed by being inserted into the groove.

The fingertip prevention means 130 is provided between the fixed body 110 and the movable door 120 to seal the space A between the fixed body 110 and the movable door 120 when the movable door 120 is opened, Thereby preventing the finger from being caught in the sliding groove 110a. The fingertip prevention means 130 may include a rotation driving unit 131 and a protective cover 135. The rotation driving part 131 is installed in the fixed body 110 and is preferably installed in the driving compartment 111 formed inside the tip of the fixed body 110 adjacent to the moving door 120 at the entrance 1 side. The rotary drive unit 131 includes a rotary drum 132 installed vertically to the drive receiving portion 111 in the fixed body 110 and connected to wind the other end of the protective cover 135, And a driving motor 133 fixed to the upper or lower portion of the housing part 111 to rotate the rotary drum 132. Here, the rotating drum 132 is connected to the rotating shaft of the driving motor 133 by a bevel gear (not shown) and rotated. Since the rotating structure using the bevel gear can be understood by a known technique, Is omitted. In addition, the rotation driving unit 131 may be configured to use not only the driving motor 133 but also other types of rotational force. For example, the rotation driving unit 131 can be configured only by the rotating drum 132 that is rotated by the restoring force of the spring elasticity, without separately providing the driving motor 133. The rotation driving mechanism that can rotate by the restoring force by providing a spring (not shown) to be connected to the rotating shaft inside the rotating drum 132 can be understood by a known technique, and a detailed description thereof will be omitted. One end of the protective cover 135 is fixed to the front end of the movable door 120 and the other end is connected to the rotation driving part 131. A finger is caught in the space between the fixed body 110 and the movable door 120 So that the space between the fixed body 110 and the movable door 120 is sealed. The protective cover 135 has a rectangular roll sheet structure that is wound or unfolded on the rotary drum 132 by driving the drive motor 133 when the movable door 120 is opened or closed. The protective cover 135 is made of a flexible material so that it can be wound around the outer peripheral surface of the rotary drum 132 when the movable door 120 is opened. In addition, the protective cover 135 is installed at a height of the entire height of the mobile door 120 in consideration of the height of the infant or the child, in order to prevent the infant or the child's fingers, In addition, advertisement contents can be printed on the front surface of the protective cover 135 to allow advertisement sponsorship, and various kinds of notices or warning phrases can be printed.

6 is a diagram showing an open operation state of a safety door having a finger-jam preventing means according to an embodiment of the present invention.

6, when the safety door 100 is opened, the sliding door 120 is slid to be inserted into the sliding groove 110a of the fixed body 110 to open the door 1. As shown in FIG. At this time, the protective cover 135 installed between the fixed wall 110 and the movable door 120 moves to the fixed body 110 and rotates in the clockwise direction by driving the driving motor 133 And wound around the outer circumferential surface. Therefore, when the movable door 120 is opened, the space between the fixed body 110 and the movable door 120 is sealed by the protective cover 135, thereby preventing the finger from being caught in the sliding groove 110a .

7 is a view showing a closed operation state of a safety door having a finger-jam preventing means according to an embodiment of the present invention.

7, in the closed operation state of the safety door 100, the movable door 120 slides out of the sliding groove 110a of the fixed body 110 to close the entrance 1. [ The protective cover 135 installed between the fixed wall 110 and the movable door 120 is moved from the outer circumferential surface of the rotary drum 132, which rotates counterclockwise by driving the driving motor 133, The space between the fixed body 110 and the movable door 120 is sealed.

The safety door having the finger-jam preventing means according to the preferred embodiment of the present invention is applied to all automatic doors in the form of a screen door that automatically opens and closes an entrance while being slid to an entrance such as an office, an elevator, Thus, it is possible to prevent a finger from being caught in the door gap, thereby preventing a safety accident in advance.

The present invention may be embodied in many other specific forms without departing from the spirit or essential characteristics of the invention.
