(Technology)

The present invention relates to a insect screen, and more particularly to a suspension roller block of the insect screen to be applied to the retractable insect screen that wraps the net using the elasticity of the spring to open and close the net more smoothly.

(Background)

Insect screens installed on doors and windows to block pests have a retractable screen that allows you to walk and walk as needed. Such a retractable insect screen is the Republic of Korea Utility Model Registration No. 354,559 (2004. 06. 25. Announcement) 'gateway screen for access doors', the inventor of the Utility Model Registration No. 400990 (2005. 11. 04 Registration) proposed the entrance screen screen.

4 and 5 is an exploded perspective view and operation of the insect screen.

As shown, the insect screen is mounted on the door, the opening and closing is mounted so as to move left and right in the four-shaped frame 10 of the horizontal frame 11 and the vertical frame 12, the guide groove 13 of the horizontal frame 11. Horse 20, which is mounted so as to move and rotate along the guide groove 13 between the support (20), the opening and closing support 20 and the vertical frame 12, the middle portion is fixed to the end 30 and one end opening and closing The other end is fixed to the support (20) and the other end is fixed to the left vertical frame 12 on the opposite side of the opening and closing column 20 around the base 30, so as to move the left and right of the opening and holding column 20 with respect to the stand 30 Winding and unwinding by walking and spreading and opening and closing the net 40, the net 40 is wound on the end 30, the spring 50 to provide a rotational force to the end 30 toward the folding side of the net 40, and opening and closing Locking the left and right movement of the support 20 is configured to include a locking device 60 for maintaining the network 40 in the expanded state. Reference numeral 14 is a connector for connecting the frame 10, and reference numeral 16 is a cover for preventing a gap between the horizontal frame 11 and the mesh 40.

In the insect screen, because the elasticity of the spring 50 acts so that the net 30 rotates in the direction in which the net 40 is wound around the bed 30, the net 40 on the bed 30 by the elasticity of the spring. The insect repellent net is opened in such a way that the opening and closing column 20 moves toward the left vertical frame 12 while winding).

And if you want to unfold the insect screen and move the opening and closing column 20 to the right with a force capable of overcoming the elasticity of the spring (50), the net 40 is released from the stand 30 and is unfolded and closed state, such The closed state is maintained by the locking device 60, and when the locking device 60 is released again, the web 30 is rolled up while being rotated by the rod 30 by the elastic force stored in the spring 50.

Such a insect screen is suspended on the horizontal frame 11 in a state where the stem 30, the spring 50 and the opening and closing column 20 mounted therein are inserted into the guide groove 13 of the upper horizontal frame 11. While moving to the left and right along the guide groove 13 in a closed state is a configuration that folds or unfolds the unfolded net 40, a suspension roller block is used for this purpose.

Figure 6 is a perspective view showing a structure in which the suspension roller block is used in the insect screen.

As shown, the spring 50 is fitted into the stand 30, the top of the spring 50 is fixed to the spring 30 to the end 30 to be rotatable, even if the stand 30 is rotated spring ( 50, the top of the suspension roller block is inserted into the guide groove 13 of the horizontal frame 11 so as not to rotate to be moved to the left and right along the horizontal frame 11 in the suspended state mounted on the guide wall (13A) ( 51 is mounted, the lower end of the spring 50 to the lower end of the spring 50 to secure the lower end of the spring 50 to the end 30 so that the lower end of the spring 50 is rotated with the end 30 The holder 52 is fitted.

Suspension roller block 51 is moved to the left and right along the horizontal frame 11 while receiving the rotation moment by the spring 50 is wound and loosened in the state that the end 30 and the spring 50 is suspended on the horizontal frame 11 Since the member 40, the suspension roller block 51 should be smoothly operated to smoothly unfold and wind the mesh 40.

When the present inventors grasp the opening and closing column 20 by hand and hit the net 40, the suspension roller block 51 when the force is not evenly transmitted to the suspended stand 30 to the horizontal frame 11 As a result, it was found that there is a problem that the opening and closing of the insect screen is not smooth because it does not move smoothly.

7 and 8 are a front view and a plan view showing a problem of the conventional suspension roller block.

As shown in FIG. 7, the body 51A of the suspension roller block 51 is fitted into the guide groove 13 of the horizontal frame 11, and the traveling rollers 51B provided on both sides of the body 51A are both sides. It moves up and down along the horizontal frame 11 in the state raised on the guide wall (13A) of, the suspension stand 30 and the spring 50 is suspended below the suspension roller block (51).

When holding and pulling the opening and closing column 20 by hand to strike the net 40, the spring 50 is wound around the stand 30 and the elastic force is accumulated. In this process, the suspension roller block 51 is guided by the spring 50. In the groove 13, the spring 50 is forced to rotate in the unwinding direction, whereby the body 51A and the traveling roller 51B are not positioned parallel to the guide groove 13, as shown in FIG. As described above, the width of the guide groove 13 and the width of the body 51A are obliquely positioned as much as the size difference.

Due to the twisting of the suspension roller block 51, both edges 51C of the body 51A are in frictional contact with the guide wall 13A, and the rotational direction of the running roller 51B is the driving direction of the suspension roller block 51. Offset from this, this phenomenon will cause the movement of the suspension roller block 51 is not smooth when hitting the net (40).

In order to eliminate the torsion of the suspension roller block 51, it may be considered to tightly determine the size of the guide groove 13 and the suspension roller block body 51A so that there is no gap, but the suspension roller block ( If the 51 is too tight, the suspension roller block 51 can not be moved smoothly, it can be said that the occurrence of the torsion of the suspension roller block 51 is inevitable.

The object of the present invention is to solve the problems related to the torsion of the insect screen suspension roller block as described above, the frictional resistance caused by the suspension roller block is twisted its position by the rotational moment of the spring when closing and closing the net This is to minimize the phenomenon that the opening and closing operation of the insect screen is not smooth.

According to the present invention there is provided a suspension roller block of the insect screen.

Suspension roller block according to the present invention, a frame consisting of a horizontal frame and a vertical frame, the opening and closing column and the mounting rod is mounted to be movable left and right along the guide groove of the horizontal frame, installed over the opening and holding pole and the vertical frame and the vertical frame And a net that is opened and opened by being wound and unfolded by winding and unwinding with respect to the brace according to the left and right movement of the brace, a spring that provides rotational force to the brace toward the fold of the net, and the net is unfolded. It is used in insect screens, including locks to keep them in place.

Suspension roller block according to the present invention, the body is fitted to the guide groove of the horizontal frame and the spring and the spring is suspended, and rotatably mounted on the body mounted on the guide wall of the horizontal frame It includes a traveling roller running along the horizontal frame.

According to a feature of the present invention, the body is rotated along the guide wall to a portion which is in contact with the guide wall by the position is shifted by the action of the spring, the body is in direct friction contact with the guide wall An anti-friction roller is formed to prevent the damage.

Preferably, the rotating shaft of the traveling roller is installed so as to correspond to the twisted angle of the body so that the rotational direction of the traveling roller coincides with the traveling direction of the body.

Hereinafter, with reference to the accompanying drawings will be described in detail the suspension roller block according to the present invention. The following embodiments are merely illustrative of the suspension roller block according to the present invention, it is not intended to limit the scope of the present invention.

1 is a front view showing the operation of an exemplary suspension roller block according to the present invention, Figure 2 is a plan view showing the operation of an exemplary suspension roller block according to the present invention, Figure 3 is another exemplary suspension roller block according to the present invention This is a plan view showing the action of.

The suspension roller block 1 according to the present invention is designed to be applied to a conventional insect screen or a screen or a screen that operates in a similar manner as described with reference to FIGS. 4 and 5. Therefore, since the overall configuration of the insect screen to which the suspension roller block 1 of the present invention is applied is similar to the insect screen of FIG. 4, the insect screen will be briefly described below.

The insect screen to which the suspension roller block 1 of the present invention is applied includes a frame 10, an opening and closing column 20, a stand 30, a mesh 40, a spring 50 and a locking device 60.

The frame 10 includes two horizontal frames 11 and two vertical frames 12 connecting the horizontal frames 11 up and down, respectively, in which guide grooves 13 are formed to face each other. The L-shaped connector 14 is assembled into a rectangular shape.

The opening and closing column 20 is inserted and mounted to move freely from side to side over the upper and lower guide grooves 13 facing the horizontal frame 11.

The stand 30 is mounted between the vertical frame 12 so as to be able to freely move from side to side in the guide groove 13 of the horizontal frame 11 up and down like the opening and closing column 20 freely. In the illustrated embodiment, the stem 30 is shown an example disposed between the left vertical frame 12 and the opening and closing column 20.

The net 40 is a conventional net woven into the net 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 and the other end of the left vertical frame 12 It is fixed to, and walks and unfolds by winding and unwinding on the stand 30 according to the left and right movement of the opening and closing column 20.

The spring 50 provides a rotational force to the stem 30 toward the side of the mesh 40 is folded to the mesh 40 is folded. In the illustrated embodiment, the spring 50 is inserted long into the stem 30 which is a circular tube.

Guide groove 13 of the horizontal frame 11 so that the top of the spring 50 is not rotated by fixing the spring 50 to the end 30 to the top of the spring 50 so that the spring 30 is rotated The suspension roller block 1 of the present invention is mounted on the guide wall 13A and mounted on the guide wall 13A to move left and right along the horizontal frame 11, and at the bottom of the spring 50, When the stem 30 rotates, a holder 52 for fixing the bottom of the spring 50 to the stem 30 is fitted so that the bottom of the spring 50 rotates together with the stem 30.

Rotating the end 30 according to the coupling relationship of the guide groove 13, the spring 50 and the end 30 such as to rotate the other end of the spring 50 in a state in which one end of the spring 50 is fixed Since the elastic force is stored in the spring (50).

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 right vertical frame 12, and when the opening and closing column 20 is released in this state, it is wound up. As the spring 50 is released, the stem 30 rotates and the mesh 40 is wound around the stem 30 so that the opening and closing column 20 moves to the left vertical frame 12, thereby folding the mesh 40. do.

Since the expanded state of the mesh 40 is forcibly rotated by the spring 50, the elastic force is stored, so that the opening and closing column 20 tries to move to the left vertical frame 12 to maintain the expanded state as it is. This blocking is realized by the conventional locking device 60 that is easy to lock and release between the opening and closing column 20 and the right vertical frame 12.

The suspension roller block 1 of the present invention includes a body 2 and a traveling roller 3. The body 2 is fitted into the guide groove 13 of the horizontal frame 11 in a state where the stem 30 and the spring 50 are suspended, and the traveling roller 3 is rotatably mounted to the body 2. The vehicle is traveling along the horizontal frame 11 while being mounted on the guide wall 13A of the horizontal frame 11.

According to a feature of the present invention, the body 2 of the suspension roller block 1 is provided with an anti-friction roller 4. The anti-friction roller 4 is installed at the portion of the body 2 which is in contact with the guide wall 13A as the suspension roller block 1 is displaced when its position is misaligned by the action of the spring 50. .

By installing the anti-friction roller 4 on the suspension roller block 1, the friction between the body 2 and the guide wall 13A when the suspension roller block 1 is driven along the guide groove 13 with the twisted roller block 1 in a broken state. Since the resistance generated by the contact is significantly reduced by the anti-friction roller 4 rotating along the guide wall 13A, the opening and closing operation of the mesh 40 becomes very smooth.

The torsion of the suspension roller block 1 by the spring 50 appears only in one direction determined by the winding direction of the spring 50 (that is, the direction in which the spring is released). Since the edges in frictional contact with the wall 13A are only two corners positioned diagonally, the anti-friction roller 4 is installed only at two corners diagonally facing the guide wall 13A as shown in FIG. Is enough.

However, when assembling the insect screen, the spring 50 is wound in the opposite direction to the prescribed direction, and when the loosening direction of the spring is reversed to the prescribed direction, the twisting direction of the suspension roller block 1 is also reversed to prevent the friction roller 4 There is a possibility that the remaining edges, which are not installed), will come into frictional contact with the guide wall 13A. In order to prevent such assembly errors, the anti-friction rollers 4 may be attached to all four corners of the body 2 to prevent such assembly mistakes. 3, by installing a pair of anti-friction rollers 4 having a large diameter before and after the body 2, anti-friction rollers irrespective of the torsional direction of the suspension roller block 1 ( 4) may work.

Preferably, the rotating shaft 3A of the traveling roller 3 is installed twisted relative to the body 2 as much as the corresponding angle of the body 2. As such, when the rotating roller 3 runs along the guide wall 13A, the suspension roller block 1 is formed so that the rotation shaft 3A is twisted on the body 2 so as to offset the distortion of the body 2. The running direction of the traveling roller 3 and the rotational direction of the same coincides with each other, so that the running of the suspension roller block 1 becomes smoother, and as a result, the opening and closing of the network 40 is smooth. 3 is based on the premise that the body 2 can be twisted in the opposite direction, so that the twisted angle of the body 2 is not specified. It would be desirable to form them in a wrong fashion with respect to 2).

As described above, but the insect screen as an object to which the suspension roller block 1 of the present invention is applied, it is obvious that the suspension roller block of the present invention can also be applied to a screen that is opened and closed in the same principle.

According to the suspension roller block 1 according to the present invention described above, the friction roller caused by the rotation moment of the spring when the suspension roller block is twisted by the rotational moment of the spring when the mesh is closed and absorbed by the anti-friction roller 4 And, since the rotational direction of the running roller 3 and the running direction of the suspension roller block (1) to match, there is an effect that the opening and closing of the insect screen more smoothly.
