[Industrial applications]

 The present invention relates to a fixing groove for a holding rope of a screen frame, which has improved operability of pushing the holding rope for fixing the end portion of the net and difficulty in coming out of the net.

[0002]

[Problems to be Solved by Prior Art and Invention]

 As shown in FIG. 4, the fixing groove of the screen door frame for fixing the end of the net has conventionally been composed of a holding piece on the side on which the net is stretched and a receiving piece opposite to the holding piece, and is inserted from the open insertion side. The net is fixed by sandwiching the presser rope that is clamped between the presser piece and the receiving piece.However, in order to prevent the presser rope from slipping out, the presser rope that has been fixed in the fixing groove is engaged from the tip of the presser piece. Since the locking piece that stops is extended to the receiving piece side, the width of the presser rope push-in port is smaller than the width inside the fixing groove, and the pressing rope is inserted while making surface contact with the receiving piece. Therefore, since the frictional resistance is large, the operability of pushing down the presser rope is generally poor, and the net is in slippery condition inside the fixing groove because it comes into surface contact with the receiving piece, and tension acts on the tension side. Out of the groove There is a high possibility.

On the other hand, in Japanese Utility Model Laid-Open No. 60-107294, the protruding amount of the locking piece to the fixing groove side is made small, the width of the introduction portion of the presser rope is widened, and at the same time, the clamping surface of the receiving piece at the fixing position. By increasing the unevenness on the bottom to reduce the resistance, the operability of pushing the presser rope is improved, and at the same time, the convex part of the clamping surface bites into the net to prevent the net from slipping out. Along with this, the width of the inside of the fixing groove also becomes wider, and the restraint of the pressing rope by the convex portion becomes less effective, resulting in a decrease in the effect of fixing this in the groove.

This invention was made in consideration of the actual situation of the conventional fixing groove, and it is an object of the invention to propose a fixing groove having a good operability for pushing the presser rope and having a stable structure against the coming out of the net. is there.

[0005]

[Means for Solving the Problems]

 In the present invention, the distance between the introduction surface facing the fixing groove and the holding piece of the introduction piece located on the push-in side of the receiving piece is determined by the distance between the holding surface facing the fixing groove and the holding piece of the holding piece located on the fixing side. The width of the fixing groove of the fixing groove is made small while making the width of the press-in port large between the pressing piece and the receiving piece having a certain external method by making it larger than the distance between the introducing surface and the locking piece. While improving the push-in operability of the presser rope, it also enhances the fixability of the presser rope by the holding surface and the presser piece.

Further, the sandwiching surface is formed in a corrugated shape in which the convex portions and the recessed portions are alternately continuous to ensure stability against the escape of the net, and in addition, at the boundary between the introduction surface and the sandwiching surface, the introduction surface is closer to the introduction surface. By forming a cutting guide groove that serves as a guide for cutting the net continuously from the convex part of the, the depth can be made large and the stability of the cutter when cutting the net is improved, The operability of the cutter is improved by positioning it closer to the clamping surface.

The receiving piece is composed of an introduction piece on the push-in port side of the presser rope sandwiching the cutting guide groove and a holding piece on the side where the presser rope is fixed. As described above, the distance between the introduction surface and the presser piece is small. By making the distance larger than the distance between the clamping surface and the pressing piece, the width of the push-in opening is wider than that of the fixing groove having a constant width in the depth direction. It becomes easy to insert into. At the same time, the holding surface is closer to the fixing groove side than the introduction surface, so that the width of the fixing portion in the fixing groove is reduced with respect to the width of the pushing opening, and the effect of restraining the pressing rope inserted in the fixing groove is increased. .

Further, since a part of the sandwiching surface has a corrugated shape, the stability against the net coming out due to the protrusion of the convex portion penetrating into the net is higher than that of the flat surface, and the cutting guide groove serves as the introduction surface. The depth of the convex surface near the introduction surface is the size of the depth from the introduction surface and the height of the convex area from the introduction surface added to the boundary with the clamping surface. It becomes larger than the case of discontinuity, and the stability of the cutter when moving is increased. Further, since the cutting guide groove is located closer to the holding surface with respect to the locking piece of the pressing piece, the angle of inclination of the cutter with respect to the horizontal plane becomes larger, which facilitates the cutting operation of the cutter.

【Example】

 The present invention will be described below with reference to the drawings showing an embodiment.

As shown in FIG. 1, the fixing groove 2 of the screen door frame 1 of the present invention faces the presser piece 3 and the presser piece 3 for holding the presser rope 7 on the tension side of the net 6 and the net 6. It is composed of a receiving piece 4 that holds the presser rope 7 on the peripheral side, and enhances the operability of pressing the presser rope 7 and the difficulty of the net 6 coming out. The presser rope 7 is fixed in a state of hitting the contact piece 5 corresponding to the bottom of the fixing groove 2.

As shown in FIG. 1, which is an enlarged view of the screen door frame 1 in the sleeping state, the pressing piece 3 is formed on the inner peripheral side of the frame assembly, and from the tip of the net 6 on the tension side, locking piece 3 ₁ presser rope 7 inserted into the fixing groove 2 is engaged overhangs the fixing groove 2 side. The middle portion of the constant in groove 2 side of the pressing piece 3 bites into the net 6 with presser rope 7, the projections 3 ₂ sandwiching the both are projected.

[Effect of device]

 The invention is as described above, and the distance between the introduction surface facing the fixing groove and the pressing piece of the introduction piece located on the push-in side of the receiving piece is set to the fixing groove of the holding piece located on the fixing side. Since the distance is larger than the distance between the clamping surface and the pressing piece that faces, the width of the fixing opening of the fixing groove can be reduced while the width of the press-in opening can be made large. The operability of pushing the rope can be improved, and at the same time, the fixing property of the holding rope by the holding surface and the holding piece can be improved. In particular, since the sandwiching surface has a corrugated shape in which convex portions and concave portions are alternately continuous, the stability against the escape of the net is enhanced.

Further, since the cutting guide groove is formed continuously at the boundary between the holding surface and the introduction surface from the convex portion of the holding surface close to the introduction surface, the cutting guide groove has a large depth, and the cutter is safe when cutting the net. Highly qualitative, especially because the cutting guide groove is located closer to the clamping surface than the locking piece, the angle of inclination of the cutter is large and cutting operability is high.
