Abstract

[PROBLEMS] To improve the insect repellent effect by doubling the structure and configuration of screen doors, and to reduce wind pressure and wind speed without impairing air permeability and daylighting performance. Provide measures such as dew condensation at low cost.
SOLUTION: A plurality of step grooves are provided on one side of a screen door frame, or a double structure is provided by providing grooves on both sides, or a screen door frame for setting is overlapped and installed in a detachable manner on an existing screen door. The above-described problem can be solved by the effect of the change in the air flow due to the resistance of the double net by forming a double screen with an appropriate interval effective for adjusting the wind pressure by the method of configuring.

Description

    The present invention relates to the structure and configuration of a double screen door.

The conventional screen door frame uses a screen door frame material with a single groove along the length direction on the outdoor side surface, and is assembled into a square or rectangular assembly by pushing a rubber or other round string into the groove with a roller or the like. The main purpose is to protect against insects, and there is no other way to prevent strong winds, pollen and fine dust than by finely meshing the mesh with fine fiber cloth.

  Conventional screen doors have a single-layer net structure for the purpose of preventing insects such as mosquitoes and flies. Condensation of glass doors caused by high winds of high floors due to changes in the era environment, flying pollen, vehicle tire dust and cold winds. It was not considered as countermeasures such as, and there was almost no effect. Recently, a type of fine fiber cloth for preventing pollen has been used in combination with a net. However, if the mesh is too fine, the inherent air permeability and lighting of the screen door are lost.

  The present invention provides a double structure by installing a plurality of step grooves on one side of a screen door frame or a double structure by providing grooves on both sides, or by installing a screen door frame for setting on an existing screen door in a detachable manner. By this method, it is possible to form a double screen door with an appropriate interval effective for adjusting the wind pressure.

  The present invention can reduce the strong wind pressure and wind speed while maintaining moderate air permeability and daylighting by the effect of airflow change due to the resistance of the double mesh of the mesh with moderate spacing. It also has a mitigating effect as a countermeasure against intrusion of abrasion dust and the like, and condensation on glass doors, and further improves the original insect-proofing effect and does not require extra costs such as special mesh materials.

  The single-sided stepped double screen door frame shown in claim 1 will be explained with reference to FIGS. A predetermined width along the lengthwise direction in each step of the cross-sectional view 3 in which the outer frame portion 8 is thickened in the thickness direction and the inner frame portion 9 is thinned to form a step of about 5 to 10 mm on one surface of the screen door frame material. A long frame material 1 and a short frame material 2 having a predetermined length provided with a depth-shaped groove 4 are formed. Two long frame members of this screen door frame material are arranged in parallel in the left-right direction, and two short frame materials are arranged in parallel vertically between the upper and lower ends thereof, and assembled into a quadrangle or rectangle shown in FIG. Fix with screws or corner members from the side.

  When strength is required for the frame such as a screen door frame for the discharge port, the middle frame member 3 having the cross section shown in FIG. On the surface of the middle frame member 3, a string mounting groove 4 having a predetermined position and a width shape is provided on the upper and lower end surfaces in the width direction along the longitudinal direction. The middle frame member 3 is passed in parallel with the upper and lower short frame members 2 on the inner frame side of the central portion of the left and right long frame members 1 assembled in the above square or rectangle, and the left and right sides are fixed with screws or the like in FIG. Install in the shape shown.

  The net stretched on the one-sided stepped screen frame is made of a fine mesh of 24 mesh or more, and a circular string 5 such as rubber is pushed into the groove 4 with a roller or the like from the mesh 6 laid on the assembled screen door frame. Cut off the remainder of the net. The two pieces of netting are performed in the later procedure for the inner frame portion first and the outer frame portion.

  The double-sided grooved door frame shown in claim 2 will be described with reference to FIGS. Grooves 4 having a cross section shown in FIG. 7 are provided on the front and back surfaces of the long frame material 1 and the short frame material 2 in a predetermined width and depth shape along the length direction.

  Using these frame materials, a rectangular or rectangular shape shown in FIG. 5 is assembled, and a mesh 6 is stretched by pressing a circular string 5 such as rubber into a groove 4 with a roller or the like from the top of the mesh 6 laid on the front and back sides of the frame. Excessive nets are excised. After putting the net on one side, turn over the frame of the screen door and repeat the above work to put the net on both sides. The middle frame member 3 having the cross section shown in FIG. 8 is used as needed in terms of strength, and is attached to the shape shown in FIG. 5 by the method according to the first aspect.

  The screen door frame for setting shown in claim 3 will be explained referring to FIGS. 9 to 14 described later. The screen door frame for setting having the cross section shown in FIG. 11 is preferably narrower than the existing screen door frame in terms of cost, and is used for attaching a round string having a predetermined width and depth along the length direction at each predetermined position on one side surface. A groove 4 is provided.

  By using the long frame material 1 and the short frame material 2 of the screen door for setting, the rectangular or rectangular shape shown in FIG. 9 is fixed and assembled with screws or corner members from the assembly thickness direction as described above. In this case, the middle frame member 3 is attached according to the method of claim 1 as necessary in terms of strength. A mesh 6 having a mesh size of 24 mesh or more is laid on the screen door frame, and the net 6 is stretched by pressing a circular string 5 such as rubber into the groove 4 from above the mesh with a roller or the like.

  The attachment member 7 shown in FIG. 13 is installed at predetermined positions on the existing screen door and the set screen door shown in FIG. 9, as shown in FIG.

  The outer peripheral side in the width direction of the screen door frame surface constituted by the long frame member 1 and the short frame member 2 is called the outer frame portion 8, and the inner peripheral side is called the inner frame portion 9. A rectangular or rectangular shape using a long frame material 1 and a short frame material, each of which is provided with a groove 4 having a predetermined width and depth along the length direction at each step provided with a step with a thicker inner frame portion 9. The screen door frame is assembled in the order of the inner frame portion to the outer frame portion, and the elastic string 5 is spread from the top of the predetermined mesh 6 spread on each frame, and is attached to the groove with a predetermined interval. A double screen door with a structure that allows heavy netting.   Using a long frame material 1 and a short frame material 2 each having a groove 4 with a predetermined width and depth along the length direction on both the front and back surfaces, assembled into a quadrangular or rectangular shape and spread on the frame one by one on the front and back surfaces. Double screen door with a structure in which a string 5 having elasticity is pushed into the groove 4 from the net 6 and attached to the groove 4 so that the net can be doubled at a predetermined interval.   A set screen door of the same structure is attached to the surface of an existing screen door provided with a single groove having a predetermined width and depth along the length direction on the outdoor side surface of the screen door frame by using a mounting member 7 or the like in a detachable manner. This is a double screen door that can be doubled with a predetermined interval.
