Caterpillar receiving unit 280 having a guide piece (283) to be guided to be naturally bent upwards, is assembled (or integrally formed) with the opening and closing column 220 (or left vertical) to move up and down; It includes.

The caterpillar 270 is a member formed by assembling a plurality of units 271 rotatably to each other to form an orbit that can be bent upwards. The caterpillar 270 has a mesh 240 and a stem 230 in the guide grooves 273 formed upward. The bottom of the is inserted is guided the left and right opening and closing movement. The recessed portion 274 formed at the lower side of the caterpillar 270 is inserted into the protrusion 291 of the pedestal 290 that supports and guides the caterpillar 270 from below, so that the left and right deployment of the caterpillar 270 is supported by the pedestal 270. Guided by 290). Pedestal 290 is connected to the lower end of the left and right vertical frame (212a, 212b) by the connector 213.

The caterpillar insect screen 200, the caterpillar 270 guides the lower end of the net opening and closing, but the caterpillar 270 is not present on the floor in the state that the net 240 is open, only the height is very low at the bottom Since only the lower pedestal 290 is present, it is possible to solve the problem of the 'sill' of the 'large screen' as described above.

In addition, if the caterpillar receiving unit 280 and the opening and closing column 220 is formed in the assembly structure capable of shanghai movement, or the caterpillar receiving unit 280 and the left vertical frame 212a is formed in the assembly structure capable of shanghai movement, If you measure the size of the entrance to be constructed in advance and manufacture the finished product at the factory and supply it to the construction site, the construction site will cover the entrances of various sizes. When the opening and holding poles, horse poles, and nets are manufactured to a sufficiently long size and supplied to the construction site, the construction site is a site-specific construction method that cuts, assembles and installs them according to the size of the corresponding entrance (hereinafter referred to as 'site-customized construction method'). Can be easily applied.

However, the above-described 'speaker insect insect net' and 'caterpillar insect insect insect repellent insect net' is a structure in which both the horseshoe net 230 is wound around the vertical door frame between the left and right vertical door frame 240, the net 240 Since the winding stage 230 has a considerable diameter and is wound up to the net 240, for example, the guide groove 273 of the caterpillar 270 may have a substantial diameter of the stem 230 and the mesh 240. It should be formed to have a wide enough to accommodate the, so that the lower end of the net 240 inserted into the caterpillar 270 is not fixed and the front and rear within the width of the guide groove (273) of the caterpillar 270 ( There is no choice but to be able to swing in a state in which a person can swing (see FIG. 11), and for this reason, a pest enters the gap between the lower end of the mesh 240 and the guide groove 273 of the caterpillar 270. Coming, or shaking the net, especially by the wind There is a problem.

An example of another caterpillar insect screen is Japanese Patent Laid-Open No. 2004-346578 (a wound screen device). The screen device of Japanese Patent Laid-Open No. 2004-346578 installs a winding shaft (corresponding to a rod) with a spring in a fixed frame or a movable frame, and wraps the screen (mesh) on the winding shaft to open and close the screen. On the other hand, the screen device to form a narrow slit in the caterpillar (screen guide), and a projection at the bottom of the screen, so that the projection is caught by the slit to prevent the screen from falling out of the slit, the gap between the bottom of the screen and the caterpillar This prevents pests from entering or swaying at the bottom of the screen.

However, the screen device of Japanese Patent Application Laid-open No. 2004-346578, “The factory manufactures a fixed frame, a moving frame, a winding shaft, and a screen with a sufficiently long size to cover various entrances and exits, and supplies them to the construction site. In reality, it is difficult to apply the site-specific construction method that cuts, assembles and installs them according to the size of the entrance. Therefore, the size of the entrance to install the insect screen is measured in advance, and the finished product is manufactured in the factory to the construction site. In addition, there is a limit to using an inconvenient construction method for supplying and installing only in the construction site, and because of the presence of a gap between the slide frame and the screen, pests may enter the gap and the top of the screen may There is a problem that can be shaken.

After the present inventor proposed the invention of Korean Patent No. 10-1005256, the present invention has been completed as a result of various studies on screens that can solve all the various problems described above.

Hereinafter, with reference to the accompanying drawings will be described in detail the door openable screen device according to the present invention. The following specific examples merely illustrate the invention and do not limit the scope of the invention.

The door opening and closing screen device according to the present invention is a device for installing a door or the like to enter and exit the person, to prevent pests or sunlight (or gaze) as necessary by winding the screen to the left or right, or below, the screen of the present invention The following description will focus on the example of applying the device to the 'Insect Screen'.

1 to 10, the screen device 1 of the present invention, the upper throttle 10, the left vertical frame 20, the right vertical frame 30, the pedestal 40, the winding shaft ( 50, a screen 60 (eg, a mesh), a spring 70, an opening and closing frame 80, a caterpillar 90, and a locking mechanism 100. The upper lateral frame 10, the left vertical frame 20, the right vertical frame 30, the pedestal 40, the winding shaft 50, and the opening / closing frame 80 may be formed of a rigid material such as aluminum, for example. The caterpillar 90 can be molded from a plastic synthetic resin.

The upper throttle 10 is a member formed horizontally long to form the upper frame of the door opening and closing screen device 1 according to the present invention, as shown in Figures 3 to 5, the first slit 11 ) And a first inner space 12. The first slit 11 is a narrow passage formed horizontally on the lower side over the entire length of the upper throttle 10 so that the upper end of the screen 60 is inserted. The first inner space 12 is formed above the first slit 11 to communicate with the first slit 11, and accommodates an upper end of the screen 60 inserted through the first slit 11. Space.

One of the objectives of the present invention is to prevent pests from entering into the gap between the upper end of the screen 60 and the upper throttle 10 and to keep the upper end of the screen stable in the upper throttle 10. 4 and 5, the width of the first slit 11 is preferably as narrow as possible in the range allowing the left and right movement of the screen 60, the first slit 11 is coupled to the mohair. The height (depth) of the first internal space 12 may be stably maintained without the upper end of the screen 60 inserted into the first slit 11 easily coming out of the first slit 11. You may want to have some depth (eg 4-6 cm).

The left vertical frame 20 is a vertically elongated member that forms a skeleton on the left side of the screen device 1 according to the present invention. As shown in FIGS. 3 and 4, the second slit 21 on the right side is formed. ) And a second inner space 22 on the left side.

The second inner space 22 is a space for accommodating the winding shaft 50 and the screen 60 wound around the winding shaft 50, and the second slit 21 is a screen wound around the winding shaft 50. The right end of 60 is a narrow passage formed vertically on the right side over the entire length such that the right end thereof is drawn out from the second inner space 22 of the left vertical door frame 20 to the right side.

When assembling the left vertical throttle 20 and the upper throttle 10, the upper side of the left vertical throttle 20 is assembled to occupy the first inner space 12 of the upper throttle 10. That is, instead of assembling the upper end of the left vertical frame 20 in the form of a T-shape under the left end of the upper lateral frame 10, for example, the upper lateral frame 10 of the upper vertical rocket 10 is disposed on the upper right side of the left vertical frame 20. Assemble the left end sideways. As the attachment part of the left vertical frame 20 and the upper lateral frame 10, an upper cover plate 51a described later can be used.

When the upper end of the left vertical frame 20 is assembled in the form of a T on the lower left side of the upper horizontal frame 10, the winding shaft 50 and the upper end of the screen 60 installed on the left vertical frame 20 will be described later. Since only the bottom of the upper throttle 10 is to be installed, a gap is generated between the lower surface of the upper throttle 10 and the upper end of the screen 60, but the left vertically has a structure as illustrated in FIG. Assembling the left end of the upper lateral frame 10 to the upper right of the frame 20, the upper end of the screen 60 can be inserted deeply into the first inner space 12 of the upper lateral frame 10 to maintain a stable. Therefore, a gap does not occur between the lower surface of the upper throttle 10 and the upper end of the screen 60, and the upper end of the screen 60 is shaken or the first inner space of the upper throttle 10 even when wind blows. Not easily depart from (12);

In assembling the left vertical frame 20 so as to occupy the first inner space 12 of the upper horizontal frame 10, the upper part of the left vertical frame 20 is applied by applying the same parts as the upper cover plate 51a. It is the simplest and easiest to assemble the left end of the upper throttle 10 laterally on the right side, but the left vertical throttle 20 does not directly occupy the first inner space 12 of the upper throttle 10. However, the connection part which is responsible for the action of the upper end of the left end of the upper throttle 10 and / or the left vertical throttle 20 is formed separately, and the left end of the upper throttle 10 and the left and the vertical length thereof are used. By assembling the upper end of the frame 20, the left vertical frame 20 consequently occupies the first inner space 12 of the upper lateral frame 10 and the upper end of the screen 60 is connected to the upper lateral frame 10. The deformation, such as being able to be inserted deeply into the first inner space 12, the left vertical frame 20 of the upper lateral frame 10 1 should be understood that the assembly to occupy an internal space (12).

The right vertical frame 30 is a member formed vertically long to form a skeleton on the right side of the screen device 1 according to the present invention. The method of assembling the right end of the upper throttle 10 and the upper end of the right vertical throttle 30 is not limited unlike the assembly of the left vertical throttle 20 and the upper throttle 10. As described above, the right end of the upper throttle 10 is laterally attached to the upper left side of the right vertical throttle 30, as well as the upper end of the right vertical throttle 30 under the right end of the upper throttle 10 T-shaped. It can also be assembled in the form. The assembly of the right end of the upper side throttle 10 and the upper end of the right vertical throttle 30 can use the connector 2 shape | molded with plastic synthetic resin etc., for example.

The pedestal 40 is a thin member having a low height formed horizontally connecting the lower end of the left vertical frame 20 and the lower end of the right vertical frame 30. The pedestal 40 serves as a lower frame of the screen device 1 of the present invention, while supporting the caterpillar 90 from below and smoothing the left and right deployment of the caterpillar. Assembling of the left end of the pedestal 40 and the lower end of the left vertical frame 20 may use a lower cover plate 51b to be described later, and assembling of the right end of the pedestal 40 and the lower end of the right vertical frame 30 is an example. For example, the connector 2 formed of a plastic synthetic resin or the like can be used.

The winding shaft 50 is a kind of rotary roller rotatably inserted into the second inner space 22 over substantially the entire length of the left vertical frame 20, and the screen 60 is wound around the winding shaft 50. Unlocked The structure for rotatably fixing the winding shaft 50 in the left vertical frame 20 is not particularly limited. For example, the upper and lower two

cover plates

51a and 51b having the rotating shaft 52 protruding from the center are used, and the upper and lower rotating shafts 52 are inserted into the upper and lower ends of the winding shaft 50, respectively. In this case, by covering the upper and lower openings of the left vertical frame 20 with

cover plates

51a and 51b, respectively, and assembling them with screws, the winding shaft 50 is rotated around the upper and lower rotary shafts 52. can do.

The screen 60 is a member that directly blocks insects or sunlight, and is a mesh in the illustrated embodiment in which the screen device 1 of the present invention is applied to a insect repellent door, and the screen device 1 of the present invention is shielded. When applied, it is cloth or synthetic resin sheet. The left end of the screen 60 is fixed to the winding shaft 50 over the entire length thereof, for example with a plunging rod 60a, and wound around the winding shaft 50 according to the rotational direction of the winding shaft 50. The right end of the screen 60 is drawn out toward the right vertical frame 30 through the second slit 21. In the illustrated embodiment, the left and right ends of the screen 60 are sewn with a band of synthetic resin, respectively, so as to act as a plunger 60a, and the plungers 60a on both sides of the screen fixing slot formed on the winding shaft 50. 50a is inserted into and fixed to the screen fixing slot 80a formed in the opening / closing frame 80 to be described later.

The spring 70 is a resilient member that applies a rotational force to the winding shaft 50 toward the side where the screen 60 is wound around the winding shaft 50 to open the screen 60. The type of spring 70 to be applied and its mounting structure are not particularly limited as long as it can perform the above-described functions. For example, the lower end of the spring 70 is fixed to the rotating shaft 52 formed on the lower cover plate 51b. While fixing the restraint 71 to the upper end of the spring 70, the restraint 71 inserted into the winding shaft 50 together with the spring 70 is the upper end of the spring 70 to the winding shaft 50 It is possible to employ a structure in which the upper end of the spring 70 rotates integrally with the take-up shaft 50 by being constrained so as not to rotate.

According to the coupling structure of the left vertical frame 20, the winding shaft 50, and the spring 70 as described above, when the winding shaft 50 rotates in one direction (the direction in which the screen is unfolded from the winding shaft and closed), The upper side of the spring 70 is rotated in one direction by the rotation of the restraint 71 which is integrally rotated with the take-up shaft 50 while the lower end of the spring is fixed to the rotation shaft 52 of the lower cover plate 51b. By rotating, the elastic force is stored in the spring, and the spring 70 in which the elastic force is stored applies a force to rotate the winding shaft 50 in the other direction (the direction in which the screen is wound around the winding shaft and opened).

Therefore, the maximum elastic force is stored in the spring 70 in a state in which the screen 60 is fully released from the winding shaft 50 and the screen 60 is closed, and the screen 60 is completely wound on the winding shaft 50. Since the minimum elastic force is stored in the spring 70 in the open state, the screen 60, which is released from the winding shaft 50 and closed, is wound on the winding shaft 50 to open the elastic force of the spring 70 toward the opening. Will receive.

The door opening and closing screen device 1 according to the present invention includes, for example, a device for adjusting the winding speed of the screen 60 between the rotary shaft 52 and the winding shaft 50 of the upper cover plate 51a, that is, a spring. It can be equipped with an adjusting device for cushioning and adjusting the elastic force of the 70.

The opening / closing frame 80 is a member formed to be vertically elongated to be movable left and right between the left vertical frame 20 and the right vertical frame 30. The right end of the screen 60 is fixed to the screen fixing slot 80a formed on the left side of the opening and closing frame 80 by, for example, a cabbage 60a, thereby moving the opening and closing frame 80 to the right. When the screen 60 is released from the take-up shaft 50, the door 60 is gradually closed, and when the opening / closing frame 80 moves to the left, the screen 60 is wound around the take-up shaft 50 to be gradually opened.

According to the characteristic of this invention, the opening-closing frame 80 is not the same shape of the whole upper and lower sides, but is a member from which the shape of the upper length adjustment part 81 and the lower caterpillar accommodation part 82 differ. The length adjusting part 81 is a part located on the upper side of the opening and closing frame 80, and like the upper end of the screen 60, the first inner space 12 through the first slit 11 of the upper lateral frame 10. It is a part that is inserted deeply to move left and right. As described above, the first slit 11 is a slit formed as narrow as possible in the range allowing left and right movement of the screen 60, and the length adjusting part 81 is inserted into the first slit 11, thereby adjusting the length. It is preferable to form the part 81 as thin as possible within the range which maintains the function of the screen apparatus 1 of this invention. The length adjusting part 81 is a portion to which the cutting is applied when the opening and closing frame 80 is to be cut to fit the size of the entrance and exit when the screen device of the present invention is constructed by a 'site custom construction method' as described below. .

In constructing the apparatus 1 of the present invention by a custom-fit method, the screen apparatus 1 according to the present invention basically has several basic standards (e.g., height 200 cm × width 100 cm and height 220 cm × width 110 cm). Since it is to be manufactured in advance, and to select the standard closest to the size of the entrance of the construction site, the construction, for example, when the total length of the opening and closing frame 80 supplied from the factory is 220cm, opening and closing that must be cut at the site-specific construction Since the length of the mold 80 is generally not longer than about 10-20 cm, the overall length of the length adjusting part 81 may be longer, but it is sufficient to set about 20-30 cm.

The caterpillar accommodating part 82 is a remaining part of the entire opening and closing frame 80 except for the length adjusting part 81, and the third internal space 83 into which the caterpillar 90 enters and exits is provided. Formed.

If the entire opening frame 80 is formed in a single shape of the caterpillar accommodating part 82 without forming the length adjusting part 81 on the upper side, the upper side of the opening and closing frame 80 may have a relatively thick width. Therefore, it cannot be inserted into the narrow first slit 11 of the upper throttle 10 described above, and the upper end of the opening / closing frame 80 can only reach a position in contact with the lower surface of the upper throttle 10. As a result, a gap may not be avoided between the upper throttle 10 and the upper end of the screen 60. However, the opening and closing frame 80 applied to the present invention forms a length adjusting part 81 having a thin width on the upper side, and thus the first inner space 12 through the narrow first slit 11 of the upper lateral frame 10. Since the gap is inserted deeply and laterally, the problem of the gap is significantly overcome.

Since the opening and closing frame 80 to be applied to the present invention has a shape of upper and lower mold release, the entire opening and closing frame 80 cannot be produced by extrusion, and should be produced by injection. Production costs can be high. In order to reduce the burden of such a cost increase, as shown in Figure 6, while forming the length adjusting portion 81 and the caterpillar receiving portion 82 as a separate member capable of extrusion molding, separately formed length adjusting portion The 81 and the caterpillar accommodating part 82 may be connected to the connecting socket 84 so that the entire opening and closing frame 80 may be formed.

The connecting socket 84 is a socket for vertically connecting the length adjusting part 81 and the caterpillar receiving part 82 which are separated from each other, and assembling the length adjusting part 81 on the upper side of the connecting socket 84 and the lower side. When the caterpillar accommodating part 82 is assembled, it becomes the complete opening / closing frame 80 of the whole.

Since the opening and closing frame 80 has a deformed shape of the length adjusting part 81 and the caterpillar receiving part 82, the length exposed to the visual field in the state in which the screen device 1 of the present invention is completed at the entrance and exit. Even if the length of the adjusting unit 81 is only about 30cm long, it may not be desirable in appearance.

In order to solve this aesthetic problem, opening and closing frame 80 may be provided with a closing frame (85). The finishing frame 85 has the same shape as that of the caterpillar accommodating part 82 in cooperation with the outer shape of the length adjusting part 81, and is assembled to the length adjusting part 81 so as to be movable, for example. In the illustrated embodiment, so that the overall appearance (outer contour of the cross-section) of the state in which the finishing frame 85 is assembled to the length adjusting portion 81 has the same appearance as that of the caterpillar accommodation portion 82, that is, the caterpillar accommodation The finishing frame 85 is formed to have an outer shape corresponding to a portion having a larger volume than the outer shape of the length adjusting part 81 in the outer shape of the part 82, and along both sides of the length adjusting part 81 along the vertical length direction. By forming the assembly step (81a, or groove), and inserting the finishing frame 85 from the top to the length adjusting section 81 using the assembly step (81a), the finishing frame 85 and the length adjusting section 81 ) Is to be the same as the outer shape of the caterpillar accommodation portion (82).

The vertical length of the finishing frame 85 is formed to be shorter than the length corresponding to the depth of the first inner space 12 of the upper side throttle 10 than the vertical length of the length adjusting portion 81, such a length difference The length adjusting portion 81 exposed to the upper side of the finishing frame 85 is inserted deep into the first internal space 12, and over the entire length of the upper and lower sides of the opening and closing frame (length adjusting portion + caterpillar receiving portion). The right end of the fixed screen 60 is also inserted deeply into the first inner space 12 and maintained in a stable sense. The portion of the length adjusting portion 81 exposed to the upper side of the finishing frame 85 is inserted into the first inner space 12 of the upper lateral frame 10 and is hardly exposed to the field of view. And aesthetic problems caused by forming into a heteromorphic shape of the caterpillar accommodating portion 82 are minimized.

The caterpillar 90 is a member similar to the caterpillar disclosed in Patent Nos. 10-1005256 and Japanese Laid-Open Patent No. 2004-346578 mentioned in the background art, and rotates in a direction in which the respective units 91 are bent upwards. It is a structure that is possibly connected.

The caterpillar 90, the left end is fixed to the lower end of the left vertical frame 20, depending on the left and right opening and closing movement of the opening and closing frame 80, the right end of the free end is developed along the pedestal 40 and left and right. In addition, it enters and exits the third internal space 83 of the caterpillar accommodating part 82. The caterpillar 90 can be fixed to the lower end of the left vertical frame 20, for example by fixing the left end to the lower cover plate 51b.

The lower end of the screen 60 of the portion released from the winding shaft 50 is inserted into the caterpillar 90 from above and held and guided. Caterpillar 90 is a U-shaped at least a portion of the upper side is open so that the bottom of the screen 60 can be inserted from above, basically the bottom of the screen 60 is inserted deeply into the caterpillar 90 is maintained There is no gap between the bottom of the screen 60 and the caterpillar 90.

Since the screen device 1 according to the present invention is a device installed at a doorway where a person enters and exits, the screen 60 may be detached from the caterpillar 90 when the screen is unintentionally different from the foot. Just inserting the bottom of the deep into the caterpillar (90) may occur a situation that does not completely prevent the occurrence of a gap, for this reason the screen device 1 according to the invention screen 60 is inserted into the caterpillar (90) It is possible to configure so that the lower end of the) does not inadvertently leave the caterpillar (90).

In order to prevent the lower end of the screen 60 inserted into the caterpillar 90 from being separated from the caterpillar 90, the caterpillar 90 communicates with an upper fourth slit 92 and a fourth slit 92. It is configured to include a lower fourth inner space 93, the lower end of the screen 60 can be attached to the separation preventing piece (61).

As shown in FIG. 7, the fourth slit 92 is a narrow passage formed horizontally upwardly in the longitudinal direction of the caterpillar 90 so that the lower end of the screen 60 is inserted, and the fourth internal space 93 is formed in the fourth slit 92. The lower space communicates with the four slits 92 and receives the lower end of the screen 60 inserted through the fourth slits 92. That is, the caterpillar 90 does not receive the lower end of the screen 60 with the entire upper surface open, but as shown in FIGS. 7 to 9, the caterpillar 90 is narrow left and right along the entire length of the caterpillar 90. The fourth slit 92 is formed, and the lower end of the screen may enter the fourth internal space 93 only through the fourth slit 92.

In the embodiment of Fig. 7, each of the units 91 is formed in a U-shape having a fourth inner space 93 that can accommodate the lower end of the screen 60, but is blocked inside the upper end of the unit 91. This is an example in which the wall 94 is formed in the lateral direction, and the fourth slit 92 is formed in the blocking wall 94 in the left and right length directions.

The separation preventing piece 61 is a member attached to the lower end of the screen 60 to prevent the lower end of the screen 60 inserted into the fourth internal space 93 from escaping upward through the fourth slit 92. . The separation prevention piece 61 may be formed over the entire length of the bottom of the screen 60, but as illustrated in FIG. 8, the detachable button type separation prevention piece having a size that cannot pass through the fourth slit 92 ( By attaching the 61 to the lower end of the screen 60 at regular intervals, the separation preventing piece 61 is caught by the fourth slit 92 so that the screen does not leave the caterpillar 90. The detachment prevention piece 61 is attached to the screen 60 in a state where the lower end of the screen 60 is sufficiently deeply inserted into the fourth internal space 93 of the caterpillar 90. It can be set to be located below the four slits 92.

According to the action of the separation prevention piece 61 of the fourth slit 92 and the fourth internal space 93 and the screen 60 of the above-described caterpillar 90, the separation prevention piece 61 is the caterpillar 90 The lower end of the screen 60 to the caterpillar 90 so as to enter the fourth inner space 93, and the screen 60 immediately above the separation preventing piece 61 is inserted laterally into the fourth slit 92. When inserted from the side, the lower end of the screen 60 can be deployed to the left and right with respect to the caterpillar 90, but the escape to the upper side is impossible, and as a result, the gap between the lower end of the screen 60 and the caterpillar 90 It is possible to more reliably prevent insects from entering or shaking the bottom of the screen 60 in the wind. Even when the screen 6 is different from the foot of the person, the bottom of the screen is separated from the caterpillar 90. Not.
