Description

[Detailed description of the invention] This invention relates to a sill slider that is used by being attached to a sill groove to ensure smooth sliding of a door. A hard plate with a large number of locking claws on both sides is embedded and integrated, leaving the locking claws, and the locking claws are pressed into engagement with the side walls of the sill groove, making it easy to install without using adhesives. Moreover, the narrow protrusions provided on the upper and lower surfaces of the thin synthetic resin strip reduce friction with the door and absorb unevenness on the bottom wall of the sill groove, allowing the door to slide smoothly. It is something to do.

The configuration of the present invention will be explained based on the embodiments shown in the attached drawings.
1 is a thin strip of synthetic resin such as polyethylene or vinyl chloride, which has a plurality of thin protrusions 2 arranged side by side in the longitudinal direction on the upper and lower surfaces, and 3 is a thin strip of a synthetic resin such as polyethylene or vinyl chloride, which has sharp tips at appropriate intervals on both sides in the longitudinal direction. A hard plate made of a metal plate made of aluminum, stainless steel, iron, etc., or a hard synthetic resin, with a number of retaining claws 4 projecting sideways, and a hard plate made of a synthetic resin thin strip of soft or hard synthetic resin and a metal plate. , or by combining a thin synthetic resin strip made of soft synthetic resin with a hard plate made of hard synthetic resin, and locking the hard plate 3 inside the thin synthetic resin strip 1 with locking claws 4...4
It is buried as a whole, leaving behind.

Note that the synthetic resin thin strip 1 and the hard plate 3 are provided with through holes 5...5 at appropriate intervals in the hard plate 3 to enhance their mutual bonding.
The upper and lower layers of the thin synthetic resin strip 1 are connected by drilling holes (Fig. 3), or the hard plate 3 is covered with the thin synthetic resin strip 1 so as to wrap the hard plate 3 with the locking claws 4 remaining. (Figure 4).

To install the sill slide as described above, by sinking the - side edge into the sill groove 6 and pushing the other side, the locking claws 4 on both sides...
. . 4 is pressed into engagement with the side walls 7, 7 of the sill groove 6 by utilizing its overall elasticity, and the locking claws 4 . . . It is fixed to the wall 8.

FIG. 5 shows another embodiment of the present invention, in which the locking claws 4 of the hard plate 3 are bored right sideways, and the upper and lower layers 9 of the synthetic resin thin strip 1 are shown in FIG. , change the 10 colors,
By providing the thin protrusions 2 on the upper and lower surfaces at corresponding positions, it is possible to use both sides, effectively extending the period of use and providing some design selectivity.

The present invention has the above-mentioned structure, and a rigid rigid plate 3 is provided inside the elastic synthetic resin cord strip 1, which is suitable for manufacturing small-thickness and narrow-width moldings such as sill slides. is embedded and integrated, and many locking claws 4 are provided protruding from both sides of this hard plate 3, so that the synthetic resin thin strip 1 is elastically attached to the side walls 7, 7 of the sill groove 6 to lock the locking claws 4. 4, the hard plate 3 presses and engages the tip part with the side walls 7, 7 of the sill groove 6 by its own rigidity, and becomes self-supporting without using conventional adhesives. Since it is fixed to the sill groove 6, installation is easy.

Furthermore, since a plurality of thin protrusions 2 are arranged in parallel on the upper and lower surfaces of the synthetic resin thin strip 1, the friction with the door is reduced by the thin protrusions 2 on the upper surface. Even if the bottom wall 8 of the sill groove 6 has some unevenness on the lower surface, the narrow protruding strip 2 on the lower surface allows the door to slide smoothly.
... 2, and can be stably installed in the sill groove 6 for a long period of time regardless of some unevenness.
