Description

Detachable screen system for window frame

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an insect screening system which is applied to a window frame of a building in a detachable manner so as to be easily installed and reused.

Generally, the outside window of the house is provided with an insect screen to block dust or pests from entering the room from outside when the window is opened.

One of the related arts is to insert a linear material with elasticity of a few millimeters in thickness between the gaps of the frame and the net together with the net in order to fix the screen net to the window frame. In this process, the linear material contracts due to the compressive force at right angles to the longitudinal direction, and the force to restore the original direction (perpendicular to the longitudinal direction) due to the elasticity of the linear material is applied to the frame of the window by the compressive force, The net can be fixed to the window frame.

One of the other prior art techniques is to connect a rectangular linear material with a net to a frame with a fixing member such as a nail or piece to secure the net to the window frame. In this process, the net can be fixed to the frame of the window by using the compressive force, frictional force, shear force, etc. introduced through the fixing member.

Another conventional technique is to fix a net to a window frame by using a net larger than the size of an opening of a window to which an insect screening network is to be installed in order to fix the net to the window frame, Cut the net.

However, such a conventional technique requires a bar-shaped tool to force a material having a thickness of a few millimeters into a gap between the frame and the mesh, and also to combine the wheel and the rod It is disadvantageous in that the workability is not good.

In addition, when a net is separated from a window frame, it can not be assembled into a frame of a window using the net again, and even if it can be assembled, there is a disadvantage that its assembly is difficult.

In order to compensate for these disadvantages, a method has been proposed for detachably attaching an insect screen to a window frame. For example, in Korean Patent No. 10-0553254 (Patent Document 1), an insect- And a roller member that is housed in a roller housing portion of the insect-proof rail formed in the frame and slides leftward and rightward, wherein the insect-control net includes a coupling protrusion coupled to an upper portion of the insect-control net to fasten the insect- A roller which is paired with the roller member and is received in the roller receiving portion; A coupling member in which a plurality of the rollers are coupled to an upper end portion; A roller shaft for coupling the roller to an upper portion of the engaging member; A securing clip engaged with the engaging projection; A fixing clip groove formed longitudinally inwardly at an inner end of the lower end of the engaging member for attaching the fixing clip to the engaging member; And a coupling protrusion receiving portion formed in a longitudinal direction at a central portion of the fixing clip groove such that the coupling protrusion is received when the coupling protrusion and the fixing clip are engaged.

However, since the conventional art such as Patent Document 1 has to be manufactured in accordance with the door frame standard, it can not be applied to existing incompatible window frames and has a complicated structure and high manufacturing cost.

SUMMARY OF THE INVENTION An object of the present invention is to provide an insect screening network which can be easily detachably attached to a window frame and can be cleaned when contaminated, .

Another object of the present invention is to provide a screening system having versatility that can be applied regardless of the standard or type of a window frame, such as being able to be mounted on and detached from an existing window frame, will be.

In order to accomplish the above object, an insect-proofing network system detachably attachable to a window frame according to the present invention comprises: a mesh sheet having a predetermined area and having flexibility; a wire having a predetermined length and slidable in the longitudinal direction at an edge of the mesh sheet; And the edge of the net sheet is attachable to the latching jaw of the window frame by the tension of the wire, and is detachable from the window frame upon releasing the tension.

The edge of the net sheet may have a refracting portion that forms a hole through which the wire penetrates, and a part of the wire is drawn out to the outside from the edge of the net sheet, Tension is applied by being pulled outward, and it is separated from the window frame through the loosening of the wire.

According to the screening system capable of being detachably attached to the window frame of the present invention, the screening screen can be easily attached to or detached from the window frame, so that the screening can be cleaned or reused if necessary, thereby maintaining cleanliness.

In addition, since the insect screen can be installed or separated with the bare hand by eliminating the separate tool or tool, the working time can be shortened, and the ease of use can be improved, thereby improving the satisfaction.

Furthermore, it is advantageous in that it is simple in structure and low in manufacturing cost, and has general versatility applicable to various types and specifications of window frames such as a new window frame including an existing installed window frame.
