Abstract

The present invention provides a screening device for opening and closing the screening screen by allowing one end of the screening screen to be wound and released on a winding roll provided in the housing, wherein the screening device is impacted by rapid winding operation by the tension of the tension spring installed in the housing, The present invention relates to a insect screening device having a damper function to prevent noise and damage to the housing and the mesh.

Insect screening device is a structure in which a net body is installed in a window or a veranda to prevent insects such as flies and mosquitoes from entering the room. If the screening device is required to be opened for various reasons, a winding roll is installed in the housing, and a spring is installed on the winding roll, and a tension force is always applied in the winding direction. Therefore, take the insect screen out of the housing and fix it by a stopper at a certain position. If necessary, release this fixing state. Then, when the winding roll is rotated by the tension of the spring, the mesh body having one end fixed to the winding roll is wound. As it is wound around the insect screen, the insect screen is stored in the housing.

The disadvantage of the screen winding structure of this structure is that the tension force of the spring does not operate constantly, but the winding roll rotates at a rapid speed so that the insect screen enters the housing in a rapid upward movement and gives a shock or noise to the user. Causes discomfort. Furthermore, when the tension is a little stronger, the insect screen is severely collided while the insect insect is caught at the bottom of the housing, and the housing is damaged or the insect insect insect is damaged.

In the present invention, a damper unit is installed at one end of the winding roll wound by a spring, and the winding roll and the mesh winding roll are connected to each other via the damper. As a result, even when rapid spring tension was applied, the rapid speed increase by the damper was prevented, so that the winding operation of the slow insect screen was possible. In particular, the damper unit used in the present invention is a structure in which two cylindrical shafts of inner and outer diameters overlap each other, so that the required frictional resistance can be changed by injecting appropriate friction oil to the joint surface without changing the structure of the insect screen of various sizes.

DESCRIPTION OF SYMBOLS 101 Cover body 102 Supporting part 102a Tip groove 105 Friction damper 105a Projection part 120 Fixing bolt 106 Winding roll 109 Adapter 100 Spring 100a Stopper 109b Intermediate section 109c Gap 100b Inner surface

In the conventional insect screen winding structure, as shown in Figs. 1 and 2, the winding roll 2 for winding the net body in the inner center of the housing 1 and the winding spring 4 are disposed inside the winding roll. (4) is supported by the support parts 11a and 11b provided in the cover 11 provided in the housing both ends. The spring is always winding in a certain direction, and the winding roll is also rotated in accordance with the winding motion to wind the insect net fixed one end here.

This winding motion is controlled by the tension of the spring (4) installed therein the speed or force. Therefore, the insect screen is released from the take-up roll and fixed to the lower stopper. When the fixed state is released, the take-up roll rotates rapidly under the tension of the spring. This rotational motion causes a collision at a considerable speed when the inlet portion 1a of the housing 1 approaches the rapid acceleration phenomenon. The noise generated during this collision gives the housewife severe discomfort. Instead of staying at this level of discomfort, the impact on the lower part of the housing causes partial breakage of the housing and damage deformation of the lower part of the mesh. It is the main cause of shortening and malfunction.

In order to solve this disadvantage, the winding operation of the winding roll may be operated by pneumatic or hydraulic piston rod, not spring. While the use of such pneumatic or hydraulic pressure ensures a more precise and stable winding roll, the oil and pneumatic system cannot be installed inside the cramped housing (1). Or the housing itself is enlarged and built in here. As a result, the increase in overall size and the adoption of expensive hydraulic and pneumatic systems have led to a rise in costs, which has been a cause of weakening competitiveness.

The present invention is to provide a insect repellent screen device that can be wound up constantly by depressing the speed automatically if the rising and falling speed of the insect screen rapidly descending by the tension of the spring.

The present invention wins the screen according to the tension of the spring at the installation site of the screen. It is an object of the present invention to provide an insect screen device that can arbitrarily adjust the rate of descent.

The present invention further goes beyond the installation of the insect screen and after a certain period of time, the tension of the spring is changed, the win of the insect screen. Even if the descending speed is changed, there is no need to dismantle and dismantle the device for winding and releasing the insect screen device to provide an insect screen device that can arbitrarily adjust the speed of the winding by simple operation from the outside.

The present invention provides a insect repellent screen device capable of opening and closing the insect repellent screen by allowing one end of the insect repellent body to be wound and released on a winding roll installed in the housing.

It is intended to provide a insect screening device without rapid winding operation over a certain speed by absorbing the rapid speed increase generated during the winding operation of the insect screen by a cylindrical friction damper.

The structure of the friction damper provided in the present invention secures a friction damper comprising an outer diameter portion having the same diameter as the support portion for supporting the spring and an inner diameter portion inserted into the outer diameter portion to the support portion, and the insect repellent mesh winding roll through the friction damper. And a spring fixed to the support portion. Therefore, the rising and falling speed of the insect screening net can be arbitrarily changed and controlled by adjusting the frictional force of the friction damper.

DETAILED DESCRIPTION Hereinafter, specific examples of the present invention will be described in detail with reference to the accompanying drawings.

The present invention is a winding roll is installed in the interior of the housing, the installed roll is fixed to the support of the cover body to cover the both ends of the housing is a spring to give tension in one direction therein the winding roll by the tension of the spring In the opening and closing screen device configured to be wound in one direction,

The protrusion 105a of the friction damper 105 having the same shape as the support portion is engaged with the tip groove portion 102a of the support portion 102 protruding inwardly of the cover body 101 which closes both ends of the housing, and then a close tension. Adjusting unit (120c) is fixed between the support and the fixing bolt 120 and between the nut (120a) and washer (120b), respectively, integrally,

Shock absorbing, characterized in that the friction damper 105 and the winding roll 106 is connected to one end of the insect repellent net through the adapter 109 to be connected by the tension of the spring 100 installed in the housing It relates to an insect screen device having a function.

In the present invention, the friction damper 105, as shown in Figure 6 was to have the same diameter and shape as the support. As a result, the fixing bolt 120 is integrated with the support by fastening together with the support and the central portion of the friction damper. The friction damper is configured such that the cylindrical inner diameter portion 100e and the outer diameter portion 100d contact each other, and an oil-based friction liquid is applied to the contact surfaces of the inner diameter portion and the outer diameter portion to increase or decrease the frictional force. Therefore, according to the selection of the oil-based friction fluid can be arbitrarily adjusted the resistance of the friction between the inner diameter portion and the outer diameter portion when rotating. The inner diameter portion is in contact with the support portion by fixing the fixing bolt 120 to the inner diameter portion 100e, and the rotational speed of the inner diameter portion and the outer diameter portion is changed while the adhesion force in contact with the support portion becomes strong. Therefore, the lifting speed of the take-up roll 106 can be arbitrarily adjusted by adjusting the appropriate fixing strength of the fixing bolt.

In the present invention, the adapter 109 has formed a gap 109c so that only the engaging protrusion 105a protruding from the outer circumferential surface of the friction damper 105 can be caught. Therefore, the friction damper and the adapter are transmitted to the winding rolls which are tensioned by the spring through the adapter by the locking projections, so that the tension is controlled by the frictional force of the friction damper even if the spring tension is strongly operated. Lose. As a result, the ascending and descending speed of the insect screen is also arbitrarily adjusted according to the frictional force setting of the friction damper.

10 to 13 show that the fixing bolt 120 penetrates from the outside of the cover body 101 through the through hole 102a formed in the center of the support part 102. , The tip of the fixing bolt was fastened from the inside by a nut (120a). Therefore, if the tightening force of the fixing bolt is adjusted at the bolt head of the fixing bolt protruding from the outside of the cover body, the tightening force applied to the tight tension adjusting device 120c disposed between the nut and the friction damper changes, so the changed force is directly applied to the friction damper. To 105. In the present invention, the close tension adjusting device 120c is provided in addition to the friction damper side and the bolt head side in contact with the cover body of the support. The tight tension adjusting device installed on the bolt head side and the bottom of the nut is used for tightening or releasing the fixing bolt from the outside when the tension tension changes due to the change of the spring tension or the change of the insect screen itself after a certain period of use after the screen is assembled. When adjusting the tension of the insect screen, the tension adjustment is impossible when the nut fastened to the fixing bolt turns together when tightening or releasing the fixing bolt. Therefore, the function of preventing the interlocking of the nut during rotation of the fixing bolt is also performed. .

In this case, after the assembly is performed, the damper function of the friction damper is strengthened or weakened by tightening and releasing the fixing bolt 120 from the outside according to the elasticity of the spring, the weight of the insect screen, and various environmental changes in the installation site. Ascending and descending speed adjustment can be arbitrarily enabled.

In the present invention, the close tension adjusting device 120c is formed with a gap 120d, and when the fixing bolt is tightened, the gap is narrowed while the bottom of the bolt head and the support part are narrowed. Thus, the gap between the nut and the washer is equally narrowed or widened. As a result, the damping force of the damper was adjusted by tightening and dismantling the fixing bolts. When this horsepower was increased, the rising speed of the take-up roll was slowed down, and in the opposite case, the rising speed was increased, allowing the screen to be arbitrarily controlled from the outside. .

In the drawing, reference numeral 120b is a washer for preventing loosening of the nut 120a.

The present invention is that the existing insect repellent mesh simply wound the tension in the housing by using the tension of the spring as it is, the rapid rise of the net to give a shock to the lower part of the housing to generate noise and vibration, rubbing the user uncomfortable The use of a damper prevents the rapid rise of speed by the operation of the friction damper when it is raised, and on the contrary, the lowering of the friction damper does not cause the friction damper to smoothly operate, thereby eliminating the aforementioned problems.

In another embodiment of the present invention, even if it is necessary to change the rising and falling speed of the insect screen according to the characteristics of the installation site as shown in Figure 10, etc. Since the pressing force of the close tension adjusting device 120c against the damper changes, a change occurs in the frictional force of the friction damper.

Therefore, according to the installation site situation, only the fastening and disassembly of the fixing bolt can be adjusted the speed of descending the screen. Therefore, according to the situation of the site or during use, the speed of descent and change or abnormal operation can be arbitrarily adjusted only by adjusting the fixing bolt from the outside without the inconvenience of replacing the whole insect screen structure conventionally. Of course, various operation adjustments were made to fit the installation site.

The present invention consequently consists of a fixed bolt inserted into the case when the speed of the insect screen is fixed in a regular form. By diversifying into the installed form, assembly and installation was freely made according to various market conditions.
