Description

ROLLER-TYPE MOTH-PROOF NET}

(Technology)

The present invention relates to a roller-type insect screen, and more particularly, when mounted on various doors such as entrance doors or windows, and it is necessary to prevent pests from penetrating into the room, the roller is drawn out along the guide from the housing to hit the net. When not in use, it is a roller screen that rolls up the net into the housing, and the net is released from the guide only for impacts that are more than enough to break the net, thereby effectively preventing the infestation of the pest, the breakage of the net and the injury of the user. It relates to a roller screen screen that can adjust the size of the mesh in the field to meet the specifications of the door.

(Background)

Insect screens are installed on various doors such as doors and windows to block pests, and there is a fixed type that is completely fixed to the door, and a retractable type that allows the insects to walk on and off the screen as needed. Sliding expression has been commonly used.

Recently, however, a mesh is wound on the top of the door to accommodate the housing, and only when it is necessary to prevent pests from penetrating into the room (e. When not in use, roller screens, which roll up the net into the housing, are widely used for their convenience.

Such a roller screen screen, the housing is fixed to the upper end of the door, the rotating roller is mounted elastically rotatably in the housing, the net is unrolled and wound on the rotating roller, and the mesh is installed on both sides of the door to the door It is common to have a configuration including a guide to guide along the unfolding.

In the early roller screen, a structure in which both ends of the net are naturally inserted into both guides is mainly used. Such a roller screen often breaks off from the guide when the net is hit, and the net is in a state of being crushed. Even if the wind is blown or only a small impact is applied to both sides of the net is stretched or separated from the guide at the moment there was a problem that the pests penetrate into the room.

In order to overcome the problem of detachment of the net from the guide, it may be considered that both ends of the net do not fall out of the guide. However, in this case, when the net is impacted, both ends of the net cannot be detached from the guide, so that the net is not damaged. There is a problem that the user is injured, and there is also a problem that the winding and unrolling operation of the net is not flexible.

Therefore, in the recent general roller type insect screen, when the impact is applied to the guide but not the degree of breakage of the net, the net is removed from the guide when the strong impact is applied without the net being separated from the guide, thereby damaging the net and the user. It is configured to prevent injury.

As a conventional roller type insect screen in this manner, there is a Korean Utility Model Publication No. 96-96. The roller-type insect screen of the present conventional utility model is configured to be in close contact between the free end and the guide of the guide strip by sewing the guide strips along both side ends of the net and guide the guide strip is inserted into the guide, the net is tight It relates to preventing the infestation of the pest by preventing the escape when operating while maintaining the state.

The conventional roller-type insect screen using the guide strip has a limit that can not be adjusted to the specification of the door is installed in the screen screen in the construction process despite the various advantages. In other words, the roller-type screening net is subjected to a series of construction processes that measure the size of the door at the construction site and build a roller-type screening net at the workplace, and then transport and install it to the construction site. If the width of the door does not match, the width of the net cannot be changed at all due to the presence of the sewn guide strips. For this reason, the screen makers must bear the cost increase and the working time due to the disposal of the incorrectly manufactured net, and the user must bear the inconvenience of pest exposure due to the delay of construction of the screen.

An object of the present invention is to solve the problems of the conventional roller screen as described above, the net is separated from the guide only for the impact more than the degree of breakage of the net so that the insect pest intrusion, breakage of the net by the network breakout and the user's In addition to effectively preventing injuries, it is to provide a roller screen screen that can shorten the construction time and reduce the cost by being able to adjust the size of the net in accordance with the specifications of the door when construction.

As shown in FIG. 1, the roller screen according to the present invention basically includes a housing 10, a mesh 20, and a guide 30, similar to a conventional roller screen.

In the housing 10, as shown in Figure 2, the upper end of the mesh 20 is fixed to the rotating roller 11 to wind and unwind the mesh 20 to receive and withdraw the housing 10, and the rotation A shaft 12 rotatably supporting the roller 11 and a spring fixing body 13A coupled between the rotating roller 11 and the shaft 12 so that the mesh 20 is the rotating roller 11. When it is released from the elasticity and includes a spring 13 for applying a force to wind the mesh 20 to the rotary roller 11 by the accumulated elasticity.

1 and 2, a pair of fasteners 14 are attached to both ends of the housing 10 to fix it to the door frame 2 or the adjacent wall surface (hereinafter referred to as door frame). . The fastener 14 is not particularly limited as long as it can securely fix the housing 10 to the door frame 2, and preferably the cover 15 and the cover 15 fixed to the side of the housing 10 and A fastener 14 including a first fastening portion 16 extending in the same plane and a second fastening portion 17 formed in a plane perpendicular to the cover 15 can be used.

The first fastening portion 16 of the fastener 14 is a fastening portion for fixing the housing 10 to the door frame 2 parallel to the cover 15, and the second fastening portion 17 is a cover 15. As the fastening portion for fixing the housing 10 to the door frame 2 perpendicular to the, respectively, the housing 10 is fixed by screws or the like. If it is not necessary to use the second fastening portion 17, it may be cut along the perforation line.

As the mesh 20 elastically wound on the rotary roller 11, a conventional mesh that is widely used as a material of the insect repellent mesh having fine meshes 21 formed in a lattice shape may be used. Since the mesh 20 is woven with very fine fibrous wires and strings, users sometimes know that there is no mesh 20 and act to break the mesh 20 or get injured.

As an alternative to solve this problem, Korean Utility Model Publication No. 2000-6626 is to make the identification strip (adhesive tape) to the mesh net vertically and horizontally to make it stand out. However, such a conventional ID strip has a difficulty in attaching the ID strip to the mesh one by one.

In the roller screen 1 of the present invention, as shown in Fig. 1, additional blades and / or strings F1 are added to the mesh 20 woven with conventional blades and strings F at predetermined intervals. Lines (L) prominent in the transverse and / or longitudinal direction of the mesh 20 are formed by weaving meshes 21S that are much denser than the basic mesh 21 of the mesh 20 by weaving very densely over a certain width. It is possible to use the mesh 20 to be formed.

The additional blades and / or strings F1 may have the same color as the basic blades and strings constituting the mesh 20 but form a prominent line L in the mesh 20 due to its density. The use of blades and / or strings (F1) with bright colors (e.g. white) of a different color than the basic blades and strings (F) of 20) makes them more visible and can form decorative patterns as a whole. It is preferable in that it exists.

The mesh 20 is guided by a pair of guides 30 at which both ends are inserted. The two guides 30 are installed long along the entire length of both sides of the door in which the roller screen 1 is installed, and as shown in FIGS. 1 and 3, preferably, both ends of the mesh 20 are inserted inward. The one side is opened in the form of a recess (c-shaped), and the opening of the recess is fixed to both sides of the door to face each other.

Detachment pieces 40 are detachably attached to both side ends of the mesh 20. The separation prevention piece 40 is elastically caught by the restriction piece 50 to be described later mounted on the guide 30, when the impact to the extent that does not damage the net 20 to the unfolded net 20, the net If the 20 is inserted into the guide 30, but more impact is applied, the net 20 is released from the limiting piece 50, so that the insects invade, breakage of the net 20 and the user. Effectively prevent injury.

The separation preventing piece 40 is not particularly limited as long as it can be detachably attached to the mesh 20, and it is preferable to use a plurality of button type separation preventing pieces 40 as shown in FIGS. 3 and 4. desirable.

Specifically, each button-type release preventing piece 40 can be configured to include a hand piece 41, a female piece 44 and the assembly screw 47. Assembling screw hole 42 is formed in the center of the hand piece 41, and the assembling protrusions 43 protrude from the periphery. The arm piece 44 has an assembly screw hole 45 is formed in the center and the assembling holes 46 into which the assembly protrusions 43 are inserted are formed in the circumference.

The button-type release prevention piece 40 is positioned on both sides of the mesh 20, the mesh piece 20 and the piece piece 41 and the female piece 44, respectively, with each of the assembling protrusions 43 After pressurized to be inserted into the assembly holes 46 of the, it is firmly attached to the mesh 20 by fastening the assembly screw 47 through the screw holes (42, 45), loosen the assembly screw 47, the mesh net It is easily removed from 20. It is not necessary to use the assembly screw 47 by increasing the binding force between the assembly protrusion 43 and the assembly hole 46.

As shown in FIG. 4, the size of the button-type release preventing piece 40 is small enough to occupy nine fine meshes 21, and the assembling protrusions 43 and the assembling holes 46 are respectively formed. Four arranged in a crisscross shape are preferable. The assembling protrusion 43 is inserted into the assembling hole 46 through the mesh 21, and the assembling screw 47 also passes through the mesh 21 so that the threaded hole 42 or the opposite side 41 or the female piece 44 is provided. 45).

As described above, each button-type release preventing piece 40 has four assembly protrusions 43 and one assembly screw 47 attached to the mesh 20 while penetrating a total of five meshes 21, and thus, a considerable load. Unless a button type release preventing piece 40 is not damaged, the mesh 21 is not damaged.

These button-type release preventing pieces 40 are attached in a line up and down along both ends of the mesh 20, the button-type release preventing pieces 40 when the mesh 20 is inserted into both guides 30 Is located inside the limiting piece 50, whereby the limiting piece 50 prevents the release of the button type release preventing pieces 40 when the button type release preventing pieces 40 attempt to leave the guide 30. It is elastically limited.

The spacing between each of the button-type release preventing pieces 40 attached in a line is such that the entire mesh 20 cannot be easily detached from the guide 30, for example, at intervals of about 300-400 mm. Can be attached in line. Thus, for example, when the height of the door is 2100MM, five button-type release prevention pieces 40 are attached to one side end of the net 20 in a row at 350MM intervals so that a total of 10 button-type release prevention pieces 40 are provided. Can be used.

The restriction piece 50 is mounted along almost the entire length of the guide 30. Restriction piece 50 may be elastically limited that the separation prevention piece 40 is separated from the guide 30 without preventing the net 20 inserted into the guide 30 to move freely up and down. Is not particularly limited.

Preferably, the limiting piece 50 is designed as a pair of elastic blades 51 mounted to face each other in the guide 30 with the inserted mesh 20 therebetween, as shown in FIGS. 3 and 5. can do. Specifically, each of the elastic blade 51 is inserted into the mounting slit 31 formed along the open end of the guide 30 and the fixing projection 52 for fixing the elastic blade 51 to the guide 30 and The elastic piece 53 which extends diagonally toward the inside of the guide 30 from this fixing protrusion 52 is formed integrally.

The elastic pieces 53 of the two elastic blades 51 face each other at a predetermined interval, and the gap is such that the net 20 can pass freely, but the separation prevention piece 40 cannot pass. Has The elastic blade 51 is made of a soft high elastic material such as high elasticity PVC, rubber, silicon.

Therefore, in the state where the mesh 20 is inserted between the two elastic blades 51 so that the release preventing piece 40 is located in the inner space of the guide 30 inside the elastic blade 51, the impact is applied to the mesh 20. When applied, the mesh 20 is to be separated from the guide 30, but the separation prevention piece 40 is caught by the elastic blade 51 to prevent the separation primarily. If a stronger impact is continuously applied, the separation preventing piece 40 presses the elastic blade 51 to the outside of the guide 30 while the two elastic blades 51 are elastically bent to closely contact each other (between the elastic blades). By eliminating the gap of the mesh 20 is pressed on both sides of the mesh 20 is more tightly fixed between the elastic blade 51 is prevented from being separated secondary. If a stronger and stronger impact is applied to the elastic blade 51 to overcome the elasticity of the elastic blade 51, the separation prevention piece 40 is pulled out while the elastic blade 51 opens and finally the mesh 20 guides. Departure from (30).

According to the action of the separation prevention piece 40 and the restriction piece 50 as described above, the restriction piece 50 does not interfere with the movement of the mesh 20 inserted into the guide 30 up and down at all without the mesh 20 (20). ) Effectively prevents breakouts, breakages and injuries to users.

As the separation prevention piece 40 is detachably mounted to the mesh 20, the roller screen 1 of the present invention can adjust the size of the mesh 20 to the size of the door to be constructed. That is, in the conventional roller-type screening nets had to re-manufacture the netting if the width of the net does not match the width of the door, the roller-type screening net of the present invention 1 to prevent the separation to fit the specifications of the door at the construction site (40) ) By removing the edge of the mesh 20, which is left unnecessarily after moving from the mesh 20, to the specification of the door, it can be used according to the specification of the door without having to manufacture the mesh 20 again.

In actual construction, prepare the mesh 20 with a slight margin, measure the width between the two guides 30 at the construction site, cut the mesh 20 accordingly, and prevent it from leaving along both ends of the mesh 20. When the piece 40 is attached, the mesh 20 can be accurately matched to the standard of the door without any error.

In the roller-type insect screen 1 of the present invention, the separation prevention pieces 40 are attached to the mesh 20 along both ends so that the separation prevention pieces (when the mesh 20 is wound into the housing 10) 40 is also wound into the mesh 20 to enter the housing 10 together. In the case of the button-type release prevention piece 40, each size is a very small component that occupies about nine meshes 21 as described above, but when several (eg, five) enter the housing 10, Due to its volume, the diameter of the roll 20 may be slightly larger than that of the mesh 20 at the position where the release preventing piece 40 is attached.

To solve this point, as shown in Figure 2, the rotary roller 11 is slightly shorter than the length of the entire width of the mesh 20 (that is, two departure prevention pieces attached to both ends of the mesh 20 ( A shorter than the length between 40) so that the anti-separation piece 40 entering the housing 10 is wound onto the shaft 12 on both sides thereof without being wound on the rotary roller 11, while the shaft 12 It is preferable to form a smaller diameter than the diameter of the rotary roller (11).

According to such a configuration, since the volume of the roll added by the release preventing piece 40 is accommodated in the space due to the diameter difference between the rotating roller 11 and the shaft 12, the mesh of the portion having the leaving preventing piece 40 is provided. It can be minimized that the diameter 20 is larger than other portions.

Typically, the upper end of the mesh 20 is fixed to the rotary roller 11 by a chock 22, etc., the lower end of the mesh 20 to the flattened straight line while keeping the mesh 20 parallel to ( 23) is mounted, the lower frame 23 is equipped with a handle portion 60, etc. to be caught when folding and expanding the mesh 20.

The lower frame 23 is not particularly limited as long as it can keep the mesh 20 flat and parallel, but preferably, as shown in FIG. 1, the handle part 60 and the parallel retaining part 70 may be assembled. It is preferable to configure so that it can be mounted.

For example, as shown in Figure 6, the lower frame 23 is typically made of an aluminum chassis, the mantle fixture 24 for fixing the bottom of the mesh 20 on the upper side is formed, the handle on the front An assembly slit 25 for assembling the portion 60 and the parallel holding portion 70 is formed over the entire length, and a strip fixing tool 26 for fixing a weather strip 27 on the lower side is provided. It is formed, and has a length corresponding to the length between the two guides (30). Since the restriction piece 50 mounted in the guide 30 is made of a soft elastic material, even if both ends of the lower frame 23 are inserted between the restriction pieces 50 (between the elastic blades), the lower frame 23 There is no problem in moving up and down along the guide 30.

Although the handle 60 is not excluded from being installed integrally or fixedly to the lower frame 23, it is preferable to be prefabricated to minimize the volume occupied when packing the roller screen (1) of the present invention. .

Specifically, for example, as shown in Figure 6, the handle portion 60 is inserted into the base 61, the base 61 is slidably inserted into the assembly slit 25 of the lower frame 23. The row handle block 62 seated in the formed groove 61A and the row handle block 62 are screwed to the base 61 in a state where the row handle block 62 is seated so that the base 61 is fixed to the assembly slit 25. It may be configured to include a handle (63) to hold in position.

Accordingly, the base 61 is inserted into the assembly slit 25 to be positioned at the center of the length of the lower frame 23, and the row handle block 62 is seated on the base 61. When the screw 64 is fastened between the thread hole 61B and the screw hole 63A of the handle 63, the handle 63 presses the base 61 to the lower frame 23, and eventually, the entire handle part 60. Is firmly fixed to the lower frame (23). When the position of the handle 63 needs to be changed, the screw 64 may be loosened slightly, and the base 61 may be moved and tightened again.

It is preferable that the lower frame 23 is prefabricated with a pair of parallel holding portions 70 which are assisted to keep the lower frame 23 parallel to the guide 30 at both ends thereof. Specifically, for example, as shown in FIG. 7, each parallel holding part 70 is provided at one side of the base 71 and the base 71 inserted into the assembly slit 25 of the lower frame 23. The cover 72, which is integrally formed and blocks the open side of the lower frame 23, is completely inserted into the assembly slit 25 so that the cover 72 opens the open side of the lower frame 23. It may be made of plastic or the like to include a guide piece 73 protruding from the base 71 through the assembly slit 25 at a position to be in contact with the inner surface of the guide 30 in the blocked state. Preferably, the upper side of the guide piece 73 is a cushioning rubber for preventing the lower frame 23 from colliding with the housing 10 by the elasticity of the spring 13 when the mesh 20 is folded ( 74) is attached.

Accordingly, when the net 20 is moved up and down, each guide piece 73 of the two parallel holding portion 70 is moved up and down together with the bottom frame 23 in a state adjacent to the inner side of the two guides 30, By limiting the swing of the frame 23 to the left and right, the entire lower frame 23 is maintained horizontal (parallel), due to the impact of the buffer rubber 74 due to the collision of the lower frame 23 and the housing 10 Noise can be prevented.

Expanded mesh 20 is subjected to the force to be wound on the rotary roller 11 again by the elasticity of the spring 13, so that the locking device 80 for blocking the winding is required to maintain the unfolded state of the mesh 20 as it is. . In the roller-type insect screen 1 of the present invention, as shown in Figure 8, the locking projection 81 and the lower end of the locking device 80 is assembled to the one mounting slit 31 of the guide 30 in the prefabricated manner. It is formed on one side of the upper end of the frame 23 can be configured as a locking projection 28 to the locking projection (81). The locking protrusion 81 is fitted to the lower end of the mounting slit 31 in the same manner as the elastic blade 51 is fitted to the mounting slit 31. For this purpose, the elastic blade 51 is the lower end of the guide 30. It extends only to the height except the length occupied by the locking protrusion 81, and the locking protrusion 81 is inserted by succession.

Therefore, when the net 20 is pulled down completely, the lower frame 23 passes over the locking protrusion 81, and when the pulling force is removed, the lower frame 23 tries to rise up again by the elasticity of the spring 13, The locking jaw 28 of the lower frame 23 is locked by the locking protrusion 81 and cannot be lifted anymore. When the locking is to be released, the lowering frame 23 is slightly pulled out so that the locking step 28 is over the locking protrusion 81.

In the illustrated embodiment, although the locking protrusion 81 is mounted on the inner mounting slit 31 of the guide 30 and the locking jaw 28 is formed inside the lower frame 23, the locking protrusion ( 81 may be mounted on the outer mounting slit 31 of the guide 30 and the locking jaw 28 may be formed on the outer side of the lower frame 23. In this case, the lower frame 23 may be used to release the locking. Slide a little and let go.

Typically, the guide 30 is fixed to the door frame 2 using a double-sided adhesive tape or screws. In addition, the lower end of the guide 30 is preferably closed so that the sharp end is not exposed. In the roller screen 1 according to the present invention, it is preferable to use a guide cap 90 having the action of fixing the guide 30 to the door frame 2 and the action of closing the lower end of the guide 30 at the same time. have.

Specifically, as illustrated in FIGS. 1 and 8 to 10, the guide cap 90 protrudes from the closing plate 91 blocking the lower end of the guide 30 and the closing plate 91 into the guide 30. A support plate 92 inserted into the closing plate 91 so as to be supported by the guide 30, and a screw hole for bending to the side of the closing plate 91 and fixed to the door frame 2. And a fixing plate 93 on which 94 is formed. Such a guide cap 90 is manufactured for the left guide and the right guide to fit the guide 30 mounted to face each other.

According to the guide cap 90 as described above, when fixing the lower end of the guide 30 to the horizontal plane, as shown in Fig. 10A, the support plate 92 is inserted into the guide 30 to the closing plate 91 of the guide. In the state where the lower end is closed, the fixing plate 93 may be horizontally extended to fix the screw to the horizontal plane, and when fixing the lower end of the guide 30 to the front vertical plane as shown in FIG. Fold it vertically and fix it with a screw. When fixing the lower end of the guide 30 to the rear vertical plane as shown in Fig. 10C, use the left guide cap 90 to fold the fixing plate 93 vertically to the rear. You can fix it.

The second fixing plate 93A having the same configuration as that of the fixing plate 93 is formed to be bendable on the opposite side of the fixing plate 93 and the guide plate ( 90) is preferable because it does not need to be produced separately for the left and right.

In the above description of the roller screen (1) of the present invention mainly described for the screen to be expanded up and down, the roller screen (1) of the present invention is to be expanded to the roller-type screen or installed below to spread sideways. It should be understood that the present invention may be applied to one roller screen, and may be applied to various screening nets that walk and mesh by rollers such as sunscreens in addition to screen screens.

In the roller-type insect screen 1 according to the present invention described above, according to the interaction of the separation prevention piece 40 and the limiting piece 50, the impact that does not reach the extent to which the mesh 20 is damaged to the mesh 20 When applied, the mesh 20 is firmly held in the guide 30, but if more impact is applied, the mesh 20 is released from the guide 30, thereby preventing pest intrusion, damage to the mesh, and injury to the user. Will be.

In addition, the roller-type insect screen 1 of the present invention is constructed so as to cut the edge of the mesh 20 unnecessarily remaining after the separation prevention piece 40 is moved from the mesh 20 to adhere to the specifications of the door. Since the size of the mesh 20 does not meet the specifications of the door, there is no need to dispose of the mesh 20. Therefore, the screen maker does not have to worry about an increase in cost due to the disposal of the incorrectly manufactured mesh and the user of the screen screen may be caused by delay in construction. You can reduce the inconvenience.

In addition, the roller screen (1) of the present invention is caused by not recognizing the existence of the mesh 20 by making it stand out by using the mesh 20 having an additional blade or seed line (F1) additionally woven tightly It can eliminate the fear of damage or injury of the mesh 20 can be.
