Description

[Detailed description of the invention] This invention relates to the sliding of sliding doors, rain shutters, etc. by providing a concave-shaped gap on the lower surface of the slippery strip at the center, and overlapping both longitudinal edges with the upper surface of the thin metal plate. This prevents deformation such as damage and warping due to changes in the expansion and contraction of these two members, which have different expansion and contraction rates, and increases the flexibility of the center part, which is most susceptible to the weight of the door and impedes slipperiness. It is characterized in that it has stable lubricity and can be firmly and easily locked in the sill groove by the locking wings left on both longitudinal edges of the thin metal plate.

The structure of the present invention will be explained based on the embodiments shown in the attached drawings.
Reference numeral 1 denotes a slippery strip made of a synthetic resin material with excellent slipperiness such as polyethylene, which has a concave cavity 2 on its lower surface in the center to make it easier to bend. A plurality of sliding strips 3...3 are provided protruding in parallel.

4 is a thin metal plate made of aluminum, steel, etc.
The slippery strip 1 is formed by using locking wing pieces 5, 5 on both sides of the longitudinal direction, and providing a number of retaining parts 6, such as punch holes, slightly inwardly.
The edges on both sides are overlapped in a bite-like manner.

The slippery strip 1 is fitted into the sill groove 7 by curving slightly upward from approximately the center point, and the elasticity of the slippery strip 1 allows the tips of the locking wings 5, 5 of the thin metal plate 4 to fit into the sill groove. It is attached to the corner portions of both sides of the seat 7 by being locked in a strongly pressed manner.

In addition, it is also possible to use the above-mentioned sill slide by attaching it to a lintel.

The present invention has the above-mentioned structure, and the thin metal plate 4 imparts rigidity to the entire sill slide, preventing the product from losing its shape or partially deforming, and allowing it to be installed while always maintaining a constant shape. At the same time, the slippery strip 1 is integrally fixed to the upper surface of the thin metal plate 4 at both edges in the longitudinal direction, and has a concave cavity 2 formed at the lower surface of the thin metal plate 4 approximately at the center thereof. This ensures a stable bond at all times by preventing peeling, damage, or partial deformation due to changes in the degree of expansion and contraction that are likely to occur due to the integral polymerization of the thin metal plate 4 with different expansion and contraction rates and the slippery strip made of resin. You can get the status.

Furthermore, when a sill slips, the center part of the sill is susceptible to the weight of the door, which impedes its smoothness. However, in the present invention, a concave cavity 2 is formed in the center of the lower surface of the sliding strip 1. Being decapitated,
Since it exhibits a buffering effect, the pressure contact between the lower surface of the door and the upper surface of the sliding strip 1 is relaxed, and the door can slide smoothly.

Further, locking blades 5, 5 are provided on both longitudinal edges of the thin metal plate 4.
Since the slippery strip 1 is polymerized while leaving the slippery strip 1, the tips of the locking wings 5, 5 are strongly pressed against the corners of both sides of the sill groove 7 due to the elasticity of the slippery strip 1 made of resin. There is no risk of it coming off the sill groove 7, and it is very easy to install.
