The door frame 10 includes an upper horizontal door frame 11 having a guide groove 11a formed downward, and two left and right vertical door frames 12 and 17 connected downwardly at both ends of the upper horizontal door frame 11. For example, it is assembled in a U-shape using two L-shaped couplers 13. Here, each door frame (11, 12, 17) is marked with a scale as shown, it is possible to cut to the exact dimensions in the field as needed. In addition, the right and vertical door frame 17 is a configuration in which the hollow portion 18, in which the caterpillar 70 is accommodated, and the mesh joint arm portion 17a to which the mesh joint 91 can be coupled in a slide form, are described in detail. It will be described together with the description of the caterpillar 70 below.

The opening and closing column 20 is inserted and mounted to be able to freely move from side to side in a state spanned between the guide groove 11a of the upper horizontal door frame 11 and the guide groove 74 of the lower U-shaped caterpillar 70. Preferably, the suspension roller 21 is mounted on the upper end of the opening and closing column 20 so as to be able to move well without friction in the suspended state by being guided by the guide groove 11a of the upper horizontal door frame 11. Such suspension rollers may be referred to, for example, "suspension roller blocks for insect screens" of the Korean Utility Model Registration No. 419330 (June 19, 2006). In addition, the opening and closing column 20 is formed with a joint groove 93a for fixing the net, and is provided with a joint 94 detachable from the joint groove 93a. In order to fix the mesh to the opening and closing column 20, first, the mesh is introduced into the joint groove 93a, and then the joint groove 93a is filled with the joint 94 to fix the mesh.

The stand 30 is disposed between the left and right door frame (12, 17) and the guide groove (11a) of the upper horizontal door frame 11 and the guide groove of the lower caterpillar (70) like the opening and closing column 20 ( 74) It is mounted so as to be able to freely rotate while being able to move freely from side to side while spanned therebetween. In the illustrated embodiment, the stem 30 is shown an example disposed between the right vertical door frame 17 and the opening and closing column 20. Preferably, the suspension roller 31 is mounted on the upper end of the horse carriage 30 so as to be able to move well without friction in the suspended state by being guided by the guide groove 11a of the upper horizontal door frame 11.

The mesh 40 is a conventional mesh woven into a mesh to prevent the introduction of pests, the middle portion of which is fixed to the end 30, one end is fixed to the opening and closing column 20, the other end of the right vertical door frame (17) It is fixed to, and is opened and closed by winding and unwinding on the stand 30 in accordance with the left and right movement of the opening and closing column 20.

The spring 50 provides a rotational force to the rod 30 toward the opening of the mesh 40 is wound around the net 30 to the net (40). In the illustrated embodiment, the spring 50 is inserted into the stem 30 in the form of a circular tube, and the top of the spring 50 does not rotate even if the stem 30 rotates on the top of the spring 50. Fixing holding (51: in the embodiment shown, the suspension roller also serves as a fixed holding) to be maintained in the guide groove (11a) in a non-state, is mounted on the lower end of the spring (50) When the rotation is rotated to maintain the lower end of the spring (50) to the stem 30 so that the lower end of the spring 50 is inserted into the rotation holding (52).

In accordance with such a coupling relationship, when the rod 30 is rotated toward the unfolding of the mesh 40, the other end of the spring 50 is wound around the spring 50 in a fixed state so that the spring 50 is wound. Is stored.

In the present invention, the state in which the elastic force 50 is stored in the spring 50 is a state in which the mesh 40 is unfolded by pulling the opening and closing column 20 to the left vertical door frame 12, and in this state, the opening and closing column 20 When the spring 50 is rolled up is released and the stand 30 is rotated and the mesh 40 is wound around the stand 30, the opening and closing column 20 is moved to the right vertical door frame 17, thereby the net 30 ) Is rolled up and opened.

Since the expanded state of the net 40 is a state in which the elastic force is stored by forcibly turning the spring 50, the opening and closing column 20 tries to move to the right vertical door frame 17 to maintain the expanded state of the net 40 as it is. It should be limited to this, for this purpose the screening device is installed locking device (60). In the illustrated embodiment, an example in which a conventional locking device that is easy to lock and release is installed between the opening and closing column 20 and the left vertical door frame 12 is illustrated.

Caterpillar 70 is a conventional caterpillar developed and modified as a wheel of the initial tracked vehicle, as shown, is a member formed as a bendable track by assembling a plurality of units 71 to be mutually rotatable.

One end of the caterpillar 70 is a fixed end and the other end is a free end. As shown in the illustrated embodiment, the left end of the caterpillar 70 is preferably a fixed end fixed to the opening and closing column 20, and the right end thereof is preferably a free end extending to the right vertical door frame 17.

This caterpillar 70 has an approximately U-shaped cross section that is at least bent upward and has an open upper side. The caterpillar 70 is formed in an approximately U-shape so that the lower ends of the mesh 40, the stem 30, and the opening and closing column 20 are moved left and right in the state where they are inserted into the U-shaped guide grooves 74. In order to guide the naturally in cooperation with the upper side door frame 11 and at the same time to block the gap between the bottom and the mesh 40 to prevent the inadvertent entry of the pest. The caterpillar 70 is bent upwardly so that when the mesh 40 is opened, the caterpillar 70 is bent upwards to be accommodated into the right vertical door frame 17. In addition, the inner side of the caterpillar 70 forms a protrusion 77 to closely contact the mesh 40 to prevent foreign substances from being introduced into the caterpillar 70.

The right vertical door frame 17 provides a space in which the caterpillar 70, which is bent and raised in the opening and closing process of the mesh 40, is accommodated. That is, the right vertical door frame 17 has a hollow portion 18 therein to accommodate the caterpillar 70 entering and bending. Further, at the lower end of the right vertical door frame 17, a bending accommodation portion 19a is formed in which the bending radius of the bending portion 72 of the caterpillar 70 is accommodated. The bending accommodating part 19a can be formed by making the lower end side of the right vertical door frame 17 shorter than the opening-and-closing support 20 or the left vertical door frame 12 by the length corresponding to the bending accommodating part 19a. That is, even if the caterpillar 70 can be bent upwards, it is difficult to bend straight to 90 degrees vertically, and the bent portion 72 has a bending radius of a certain size. The right vertical door frame 17 has such a bending radius. The lower side may be shorter than the length of the opening and closing column 20 or the left vertical door frame 12 by the length enough to be accommodated to form the bent accommodation portion 19a.

Preferably, the guide piece 19 for guiding the flexible upward bending of the caterpillar 70 is attached to the bent accommodation portion 19a of the right vertical door frame 17. The guide piece 19 is shaped into a shape corresponding to the bending radius of the caterpillar 70, for example, made of plastic, or the like, and is detachably attached to the lower end of the right vertical door frame 17, for example.

On the other hand, the insect screen of the present invention may be applied to the pedestal 73 supporting the caterpillar 70 between the left and right door frame 12, 17 on both sides. This pedestal 73 is not a protruding, grooved member like a typical lower side door frame (not shown), but the caterpillar 70, which is folded and unfolded as a substantially flat plate-like member so that there is no catch or groove, is in direct contact with the floor. It serves to prevent and smoothly guide the folding of the caterpillar (70).

As shown, by forming a low height protrusion 73a on the upper surface of the pedestal 73 to be naturally inserted into the bottom recess portion 75 of the caterpillar 70, it is possible to guide the unfolded caterpillar 70. Although FIG. 3 exaggerated largely so that the structure of the pedestal 73 can be grasped clearly, what is necessary is just to form it in the near flat plate which is slightly convex actually.

In the illustrated embodiment, the left and right door frames 12 and 17 are connected by connecting the lower ends of the left and right door frames 12 and 17 using the connector 76 and the guide piece 19. The upper horizontal door frame 11 and the pedestal 73 form a square frame as a whole, so that the pedestal 73 reinforces the structural strength of the insect screen, while attaching the insect screen to the door is convenient, but the pedestal 73 It is also possible to attach to the floor (bonding, etc.) without connecting to the left and right door frame (12, 17). In addition, the scale is displayed on the surface of the pedestal 73, it is also possible to cut and install the custom in the field.

In the illustrated embodiment, a joint groove 91a is formed in the mesh joint 91 provided in the right vertical door frame 17, and a joint groove 32 is formed in the stem 30, and the opening and closing column ( The joint groove 93a is also formed in 20, and when the joints 92, 94 and 96 are crimped thereto, the net 40 can be fixed respectively.

Hereinafter, the operation of the insect screen according to the present invention will be described with reference to FIG.

First, when the locking device 60 is released, while the stand 30 is wound around the net 40 by the action of the spring 50, the stand 30 and the opening and holding column 20 are moved to the right vertical door frame 17 while being opened. Becomes At this time, the lower end of the stand 30 and the opening and closing column 20 is guided by the caterpillar 70 in the state inserted into the U-shaped guide groove 74 of the caterpillar 70, the right end of the caterpillar 70 is bent in sequence While being accommodated into the bent receiving portion 19a of the guide piece 19 of the right vertical door frame 17, the threshold is not present in the open state of the mesh 40.

Holding the handle formed in the opening and closing column 20 to close the net 40, and pulled to the left, the net 40 is released from the stand 30, the stand 30, the opening and holding column 20 is the left vertical door frame 12 Towards the movement, when the locking device 60 is locked, the mesh 40 sags.

As the net 40 is unfolded, the caterpillar 70 accommodated in the bending receiving portion 19a is gradually drawn out from the right vertical door frame 17, and the lower end of the stand 30 and the opening and closing column 20 are separated from the caterpillar 70.
