Abstract

[Object] To provide a holding member for a net for a screen door effective for fixing a net for a screen door having fine filaments and a fine mesh compared with a known insect protection net to a frame body for use in a screen door.

[Solving Means] A holding member 14 is constructed by providing a pair of elastically deformable leg ridges 16 being fitted into a latch groove 18 under a condition of being in pressure contact with an inward projecting edge 19 thereof, to a cover plate 15 for covering the latch groove 18. A soft pressure-contact portion 15a being in pressure contact with the net 12 sandwiched between the same and an outer surface 19a of the inward projecting edge 19 of the latch groove 18 is integrally formed at an outer side of the leg ridge 16 of the cover plate 15. In the pressure-contact portion 15a, an acute head-shaped projecting ridge 15b being elastically in pressure contact with the net sandwiched between the same and the outer surface of the inward projecting edge 19 of the latch groove 18 is projected and the projecting ridge has elasticity so as to be deformed by unevenness of the net surface.

Claims

1. A holding member for a net for a screen door made of synthetic resin, for fixing a net by being pushed into a latch groove formed by narrowing a mouth portion by an inward projecting edge at an inner periphery of one surface along which the net is tightly stretched in a rectangular frame body for use in a screen door, together with a net for the screen door,

wherein the holding member is constructed by being provided with an elastically deformable leg portion to be fitted to the latch groove under a condition of being in pressure contact with the inward projecting edge on a cover plate for covering the latch groove, and

wherein a soft pressure-contact portion to come in pressure contact with the net sandwiched between the same and an outer surface of the inward projecting edge in the latch groove is integrally formed on an outer side of the leg portion of the cover plate, and

wherein an acute tip end-shaped projecting ridge elastically comes in pressure contact with the net sandwiched between the same and the outer surface of the inward projecting edge of the latch groove is projected on the pressure-contact portion, and

wherein the projecting ridge has elasticity so as to be deformed by unevenness of a net surface.

2. The holding member for a net for a screen door according to claim 1, wherein the frame body for use in the screen door comprises the latch groove comprising a narrowed mouth portion between a pair of confronting inward projecting edges,

wherein the leg portion is constructed of a pair of elastically deformable leg ridges fitted into the latch groove under a condition of being in pressure contact with inward projecting edges, respectively, on both sides of the mouth portion via the net, and

wherein the pair of leg ridges respectively comprises slope portions to come in pressure contact with tip ends of the inward projecting edges of the latch groove when being pushed into the latch groove on outer sides of the tip end portions via the net, and wherein latch projections provided with latch edges for latching the holding member inside the projecting edge via the net when the operation for pushing the holding member into the latch groove is completed are respectively provided, and

wherein the latch edge of the latch projection is formed on a slope portion on a backside of the slope portion on the outer side of the tip end portion of the latch projection.

3. The holding member for a net for a screen door according to claim 1, wherein the frame body for use in the screen door comprises the latch groove comprising a narrowed mouth portion between an inner peripheral plane of the frame body for use in the screen door and an inward projecting edge opposite thereto,

wherein the leg portion is constructed of an elastically deformable leg ridge being fitted into the inward projecting edge under a condition of being in pressure contact therewith via the net, and a contact plate portion for holding an inserted state while being in contact with the inner peripheral plane of the frame body for use in the screen door, and

wherein the leg ridge comprises the slope portion being in pressure contact with a tip end of the inward projecting edge of the latch groove via the net when being pushed into the latch groove on an outer side of the tip end portion, and comprises a latch projection including a latch edge to be latched with an inside of the projecting edge via the net in completion of pushing the holding member into the latch groove, and

wherein the latch edge of the latch projection is formed on the slope portion on the backside of the slope portion on the outside of the tip end portion of the latch projection.

4. The holding member for a net for a screen door according to any one of claims 1 through 3, wherein an acute tip end-shaped projecting ridge being elastically deformed by being in pressure contact with the net is provided in the pressure contact portion of the cover plate, in at least one in number.

5. The holding member for a net for a screen door according to any one of claims 1 through 4, wherein the acute tip end-shaped projecting ridge projecting on the pressure contact portion is formed to have a height wherein when the leg ridge is pushed into the latch groove without allowing the net to intervene, and a latch edge of the leg ridge is latched inside an inward projecting edge of the latch groove, a tip end of the projecting ridge comes in contact with an outer surface of the inward projecting edge.

6. The holding member for a net for a screen door according to any one of claims 1 through 5, wherein a thin-walled elastic deforming portion is formed at a center portion of a cover plate covering a latch groove, and between coupling portions of a pair of leg ridges, or between coupling portions of the leg ridge and the contact plate portion.
