Abstract

A closing device includes a keeper provided with a retaining element for retaining a bolt in the keeper in a closed position of the device. The retaining element is mounted to be pivotable about and to be axially movable on a rod provided in the keeper and is resiliently biased to both axially slide on and pivot about the rod in such manner that, in an active position, the retaining element projects into an extension of an opening into which the bolt is capable of entering so as to close the device, and it is brought to a retracted position by axially sliding along the rod while being automatically returned to its active position from its retracted position as soon as the bolt is extracted from the keeper under the effect of the resilient force exerted by a spring.

Dependent claims

A closing device for relatively immobilizing two elements one of which is movable relative to the other between closed and open positions, said closing device comprising:

a bolt to be mounted on a first of the elements;
a keeper to be mounted on a second of the elements;
said keeper including hook means for hooking engagement with said bolt when the two elements are in the closed position and said bolt extends into said keeper;
said keeper including a retaining element having said hook means and mounted for axial movement along an axis between an armed position whereat said hook means may be engaged by said bolt, and an unarmed position, whereat said hook means may not be engaged by said bolt, and said retaining element also being mounted for pivotal movement about said axis;
said keeper including resiliently yieldable means for biasing said retaining element axially of said axis toward said armed position and for pivotally biasing said retaining element about said axis in a direction such that said hook means is urged toward and beyond a position of hooking engagement with said bolt, such that when said retaining element is in said armed position and the two elements are in the closed position said hook means engages with said bolt;
and
opening control means, mounted on said keeper, for selectively moving said retaining element axially along said axis against the axial biasing force of said resiliently yieldable means from said armed position to said unarmed position, and thereby for moving said hook means out of engagement with said bolt, whereupon the pivotal biasing force of said resiliently yieldable means pivots said retaining element in said direction about said axis, such that with the two elements in the closed position said bolt extending into said keeper forms a stop abutted by said retaining element under said axial biasing force of said resiliently yieldable means and maintaining said retaining element in said unarmed position, and such that upon movement of the two elements to the open position said bolt is withdrawn from said keeper and from abutment with said retaining element and said axial biasing force of said resiliently yieldable means moves said retaining element axially along said axis to said armed position.

4 more elements

An article, particularly an article of luggage, comprising two elements relatively movable between closed and open positions, and at least one closing device for maintaining said two elements in said closed position, said closing device comprising:

a bolt mounted on a first said element;
a keeper mounted on a second said element;
said keeper including hook means for hooking engagement with said bolt when the two elements are in said closed position and said bolt extends into said keeper;
said keeper including a retaining element having said hook means and mounted for axial movement along an axis between an armed position whereat said hook means may be engaged by said bolt, and an unarmed position, whereat said hook means may not be engaged by said bolt, and said retaining element also being mounted for pivotal movement about said axis;
said keeper including resiliently yieldable means for biasing said retaining element axially of said axis toward said armed position and for pivotally biasing said retaining element about said axis in a direction such that said hook means is urged toward and beyond a position of hooking engagement with said bolt, such that when said retaining element is in said armed position and said two elements are in said closed position said hook means engages with said bolt;
and
opening control means, mounted on said keeper, for selectively moving said retaining element axially along said axis against the axial biasing force of said resiliently yieldable means for said armed position to said unarmed position, and thereby for moving said hook means out of engagement with said bolt, whereupon the pivotal biasing force of said resiliently yieldable means pivots said retaining element in said direction about said axis, such that with said two elements in said closed position said bolt extending into said keeper forms a stop abutted by said retaining element under said axis biasing force of said resiliently yieldable means and maintaining said retaining element in said unarmed position, and such that upon movement of said two elements to said position said bolt is withdrawing from said keeper and from abutment with said retaining element and said axial biasing force of said resiliently yieldable means moves said retaining element axially along said axis to said armed position.

4 more elements

A closing installation, particularly for a building, comprising a first panel and a second panel mounted for movement in directions substantially parallel to said first panel between closed and open positions, and at least one closing device for maintaining said second panel in said closed position, said closing device comprising:

a bolt mounted on one of said panels;
a keeper mounted on the other of said panels;
said keeper including hook means for hooking engagement with said bolt when said second panel is in said closed position and said bolt extends into said keeper;
said keeper including a retaining element having said hook means and mounted for axial movement along an axis between an armed position whereat said hook means may be engaged by said bolt, and an unarmed position, whereat said hook means may not be engaged by said bolt, and said retaining element also being mounted for pivotal movement about said axis;
said keeper including resiliently yieldable means for biasing said retaining element axially of said axis toward said armed position and for pivotally biasing said retaining element about said axis in a direction such that said hook means is urged toward and beyond a position of hooking engagement with said bolt, such that when said retaining element is in said armed position and said second panel is in said closed position said hook means engages with said bolt;
and
opening control means, mounted on said keeper, for selectively moving said retaining element axially along said axis against the axial biasing force of said resiliently yeildable means from said armed position to said unarmed position, and thereby for moving said hook means out of engagement with said bolt, whereupon the pivotal biasing force of said resiliently yieldable means pivots said retaining element in said direction about said axis, such that with said second panel in said closed position said bolt extending into said keeper forms a stop abutted by said retaining element under said axial biasing force of said resiliently yieldable means and maintaining said retaining element in said unarmed position, and such that upon movement of said second panel to said open position said bolt is withdrawn fron said keeper and from abutment with said retaining element and said axial biasing force of said resiliently yieldable means moves said retaining element axially along said aixs to said armed position.
