Abstract
An anti-finger-catching system in which elastic sections are fitted to the edges of the leaves of doors and windows, and optionally to the edges of their frames to prevent the user's fingers from being accidentally caught between the frame and the leaf The leaf has, on its front edge, a closing mechanism, fitted with a retractable bolt, whose rear part has a slot running along it through which a driver passes transversely, the driver being connected to operating knobs. The bolt also has an intermediate stop with a spring acting on it and tending to keep it in its protruding position; and a front part that is longer than the thickness of the elastic section.
Claims18
An anti-finger catching system for doors and windows, said anti-finger catching mechanism comprising:
- a frame,
- a moveable leaf attached to the frame and the moveable leaf having, on front and rear edges, elastic sections for preventing a user's fingers from being accidentally trapped between the frame and the moveable leaf,
- a closing mechanism of the moveable leaf being fitted with a retractable bolt acting against the frame for holding the leaf in a closed position and said closing mechanism being retractable upon contacting the user's fingers for preventing the user's fingers from being trapped between the frame and the closing mechanism of the moveable leaf;
- said bolt having a rear portion with an elongated longitudinal slot through which a driver passes transversely, said driver being linked to operating knobs, and a section of the bolt located between an intermediate stop and a front portion of the bolt being longer than the elastic section mounted on the front edge of the moveable leaf so that the section of the bolt can extend through the elastic section mounted on the front edge of the leaf and engage the frame with the section of the bolt being fully retractable into the leaf by movement of the driver in the elongated longitudinal slot upon contacting fingers between the frame and the leaf.
A latching mechanism of an anti-finger catching system for doors and windows having a frame and a moveable leaf having an elastic section on a front edge, said latching mechanism comprising:
- a box casing for being recessed in the front edge of the moveable leaf,
- a retractable bolt having a rear portion with an elongated longitudinal slot that allows sliding of an associated driver, the driver being linked to operating knobs, and a section of the bolt between an intermediate stop and a front portion of the bolt being of a predetermined length for extending through the elastic section mounted on the front edge of the leaf, and
- a spring housed inside the box casing acting on a rear end of the box casing and on the intermediate stop to keep the section of the bolt in a protruding position and for allowing retraction of the section of the bolt into the leaf by sliding of the driver in the elongated longitudinal slot when the bolt engages a user's fingers located between the bolt and the frame.
An anti-finger catching system for doors and windows, said anti-finger catching system comprising:
- a frame,
- a moveable leaf having an elastic section on a front edge, and
- a closing mechanism including a box casing recessed in the front edge of the leaf, a retractable bolt having a rear portion with an elongated longitudinal slot that allows sliding of an associated driver, the driver being linked to operating knobs, and a section of the bolt located between an intermediate stop and a front portion of the bolt being longer than the elastic section mounted on the front edge of the moveable leaf so that the section of the bolt can extend through the elastic section and engage the frame, and a spring housed inside the box casing acting on a rear end of the box casing and on the intermediate stop to keep the bolt in a protruding position and for allowing full retraction of the bolt by movement of the driver in the elongated longitudinal slot when the bolt engages a users fingers located between the bolt and the frame.
