Abstract

A securing device for a window includes a fixed support, a slide rod pivoted to the window and displaceably passed through a transverse hole of the fixed support, and a knob screwed into an axial screw hole of the fixed support for securing the slide rod after the window is moved to an intended position; a pair of curved pads is used for protecting the slide rod from scratching of the fixed support; each pad has a curved main body with convex and concave sides, an engaging protrusion on the convex side, and several ribs formed around and connected to the engaging protrusion; the pads are respectively positioned in the axial hole, and the fitting cavity with the concave sides facing each other, and with the ribs being pressed against inner sides of the fixed support for preventing the pads from falling off.

Claims

1. A securing device for a window, comprising:

a support body fixed in position;

the support body having an axial screw hole, and a transverse through hole communicating with the axial screw hole;

the support body having a fitting cavity adjacent to the transverse through hole and communicating with the axial screw hole;

a slide rod having a first end adapted to be pivoted to the window and displaceably passed through the transverse through hole of the fixed support body;

a stopping block being screwed onto a threaded second end of the slide rod for preventing the rod from separating from the fixed support body;

a knob screwed into the axial screw hole of the support body for securing the slide rod in position after the window has been moved to an intended position; and

a pair of curved pads for protecting the slide rod from scratching of edges of the transverse through hole;

each curved pad having a curved main body with convex and concave sides, an engaging protrusion on the convex side, and a plurality of ribs formed around and connected to the engaging protrusion;

the curved pads being respectively positioned in the axial screw hole and the fitting cavity of the support body, the concave sides of the curved pads facing each other;

the curved pads being held in position with the ribs being pressed against inner sides of the support body;

a width of the curved pads being smaller than a diameter of the slide rod;

a vertical distance from a top of the engaging protrusion of each curved pad to a lower edge of the curved main body being smaller than one half of a diameter of the transverse through hole.
