Abstract

There is provided a slide cover for a slide fastener. A pair of second guide element passages are formed in a space among an upper plate, a lower plate, a pair of outer wall portions and a pair of inner wall portions to guide a pair of separated element rows into a first element guide passage of a slider. The upper plate, the lower plate and a connection post have a concave surface, which is recessed in a disengaging direction of the slider, in a surface facing toward an engaging direction of the slider. The pair of second guide element passages are configured so that tip ends of the pair of inner wall portions in the engaging direction are located at the same positions as or at a side of the engaging direction relative to tip ends of the pair of outer wall portions in the engaging direction.

First claim

The invention claimed is:

1. A slide cover for a slide fastener, to be mounted to a slider comprising a slider body having an upper blade and a lower blade arranged to face each other with an interval in an upper-lower direction, a guide post configured to connect front portions of the upper blade and the lower blade at intermediate portions thereof in a right and left direction, and a Y-shaped first element guide passage formed by the upper blade, the lower blade and the guide post, the slide cover comprising:
an upper plate to be mounted to the upper blade;
a lower plate to be mounted to the lower blade;
a connection post configured to connect the upper plate and the lower plate in the upper-lower direction and comprising a pair of inner wall portions configured to respectively guide engaging portion-sides of a pair of element rows of the slide fastener;
a pair of outer wall portions configured to respectively guide opposite sides of the pair of element rows to the engaging portion-sides and protruding from at least one of the upper plate and the lower plate so as to narrow an interval between the upper plate and the lower plate, and
a pair of second guide element passages formed in a space among the upper plate, the lower plate, the pair of outer wall portions and the pair of inner wall portions and configured to guide the pair of separated element rows into the first element guide passage,
wherein the upper plate, the lower plate and the connection post have a concave surface, which is recessed in a disengaging direction of moving directions of the slider, in a surface facing toward an engaging direction of the moving directions of the slider, and
wherein the pair of second guide element passages are configured so that tip ends of the pair of inner wall portions in the engaging direction are located at the same positions as tip ends of the pair of outer wall portions in the engaging direction or located at a side of the engaging direction relative to the tip ends of the pair of outer wall portions in the engaging direction.

2. The slide cover for a slide fastener according to claim 1 , wherein the pair of second guide element passages are configured so that intervals between the outer wall portions and the inner wall portions which face each other become narrower toward a tip end portion-side thereof in the engaging direction relative to a disengaging direction-side thereof.

3. The slide cover for a slide fastener according to claim 2 ,
wherein as seen in the upper-lower direction, an inner surface shape of each of the outer wall portions is one linear shape,
wherein an inner surface shape of each of the inner wall portions is a bent shape comprising a first linear portion arranged at the engaging direction-side and a second linear portion arranged at the disengaging direction-side,
wherein the second linear portion has a shape parallel with the inner surface shape of each of the outer wall portions, and
wherein the first linear portion has a shape inclined relative to the inner surface shape of each of the outer wall portions and coming close to each of the outer wall portions toward the tip end portion-side in the engaging direction.

4. The slide cover for a slide fastener according to claim 1 ,
wherein the upper plate and the lower plate are configured as separate members,
wherein the connection post has a concave wall portion forming the concave surface and a connection portion configured to connect the upper plate and the lower plate in the upper-lower direction at a side of the disengaging direction relative to the concave wall portion,
wherein the concave wall portion has an upper concave wall portion configuring an upper side of the concave surface and protruding downward from the upper plate and a lower concave wall portion configuring a lower side of the concave surface and protruding upward from the lower plate,
wherein the upper concave wall portion and the lower concave wall portion overlap with each other in the upper-lower direction, overlapping surfaces-side thereof are respectively provided with a first groove portion and a first ridge portion to be fitted to the first groove portion, and
wherein the first groove portion and the first ridge portion are located at the side of the engaging direction relative to the connection portion.

5. The slide cover for a slide fastener according to claim 1 ,
wherein the upper plate has an upper mounting portion to be mounted to the upper blade,
wherein the upper mounting portion has an upper surrounding portion configured to surround a part of an outer periphery of the upper blade and an upper covering portion configured to cover at least a part of an upper surface of the upper blade, and
wherein the upper surrounding portion constitutes an outer side of an upper hole penetrating the upper plate.

6. The slide cover for a slide fastener according to claim 5 ,
wherein the slider comprises the slider body further having a pull tab attachment portion protruding from the upper surface of the upper blade, in addition to the upper blade, the lower blade, the guide post and the first element guide passage,
wherein the upper covering portion has a pair of upper protruding portions protruding from the pair of second guide element passages of the upper plate so as to narrow the upper hole, and
wherein an interval between the pair of upper protruding portions is set to a dimension within which the pull tab attachment portion provided on the upper surface-side of the upper blade is interposed.

7. The slide cover for a slide fastener according to claim 1 ,
wherein the lower plate has a lower mounting portion to be mounted to the lower blade,
wherein the lower mounting portion has a lower surrounding portion configured to surround a part of an outer periphery of the lower blade and a lower covering portion configured to cover at least a part of a lower surface of the lower blade, and
wherein the lower surrounding portion constitutes an outer side of a lower hole penetrating the lower plate.

8. The slide cover for a slide fastener according to claim 7 ,
wherein the slider comprises the slider body having a pull tab attachment portion protruding from the lower surface of the lower blade, in addition to the upper blade, the lower blade, the guide post and the first element guide passage,
wherein the lower covering portion has a pair of lower protruding portions protruding from the pair of second guide element passages so as to narrow the lower hole, and
wherein an interval between the pair of lower protruding portions is set to a dimension within which the pull tab attachment portion provided on the lower surface-side of the lower blade is interposed.

9. The slide cover for a slide fastener according to claim 1 ,
wherein the upper plate has a pair of upper guide portions configured to guide upper surfaces-side of the pair of element rows, an upper bonding portion bonding the pair of upper guide portions, and an upper mounting portion formed in cooperation with the pair of upper guide portions and the upper bonding portion and configured to mount the upper plate to the upper blade,
wherein the upper mounting portion has a pair of upper leg portions protruding from the pair of upper guide portions in the disengaging direction and configured to interpose the upper blade therebetween, in addition to the pair of upper guide portions and the upper bonding portion,
wherein the lower plate has a pair of lower guide portions configured to guide lower surfaces-side of the pair of element rows, a lower bonding portion bonding the pair of lower guide portions, and a lower mounting portion formed in cooperation with the pair of lower guide portions and the lower bonding portio
