Abstract
An economical, efficient window stop includes a narrow, flat housing having first and second cavities for respective flat, narrow bolt and latch. The bolt is spring braced and movable between a first portion within the cavity and a second position extending from the cavity. The latch is spring biased and moves transverse to the movement of the bolt. High strength molded plastic construction with guide means and close tolerances allow efficient distribution of forces from the extended bolt to the housing.
Claims20
A stop means for limiting movement of a sliding window along a predetermined path of window movement, the stop means comprising:
- a housing adopted to be positioned adjacent and out of said path of window movement, said housing having a first cavity and a second cavity adjacent to each other;
- a bolt operatively associated with said first cavity being moveable along a predetermined first path between a first position wherein said bolt is locked within said first cavity against an outward bias and a second position wherein a first portion of said bolt extends out of said first cavity and a second portion of said bolt remains within said first cavity;
- said first portion of said bolt in said second position adopted to extend into said path of window movement so as to contact said sliding window to define said limit of movement of said window along said path of window movement at which point of contact said second portion transfers forces resulting from said contact to said housing;
- a latch within said second cavity moveable along a predetermined second path in a direction transverse to said first path between a first position biased toward and engaging said bolt, and a second position removed from engagement with said bolt;
- an actuator on said latch for facilitating movement of said latch between said first position and said second position to unlock said bolt;
- a spring positioned between said housing and said bolt biasing said bolt toward said second position;
- and,
- a guide comprising a tongue and groove arrangement between said bolt and said housing to maintain said bolt within close tolerance of said first path, and to guide said bolt along said first path, and to transfer lateral loads from said bolt to said housing, said bolt receiving said lateral loads from said contact of said sliding window with said first portion of said bolt.
A window stop means adapted to be positioned in a track of a sliding window adapted to move in a horizontal path, the window stop means comprising:
- a narrow, elongated housing adapted to be fitted within the track of said sliding window whereby it will not interfere with the travel of said window in said track;
- a bolt slidably mounted in said housing, said bolt being moveable vertically between a first position within said housing and thereby out of the path of said window and a second position extending vertically out of said housing into the path of said window whereby the bolt is able to contact said window;
- a latch mounted within said housing movable horizontally between a first position biased onto engagement with said bolt means, and a second position removed from engagement with said bolt means;
- and
- a guide comprising a tongue and groove arrangement between said bolt and said housing to guide said blot between said first and second positions, and to transfer lateral loads from said bolt to said housing, said bolt receiving said lateral loads from said contact of said window with said bolt;
- said bolt, latch and housing being of close interfitting relationship whereby horizontal impact forces received by said bolt will be transferred to said housing.
A stop for limiting movement of a sliding window along a path of sliding window movement, the stop comprising:
- a housing adapted to be positioned adjacent the path of sliding window movement, the housing having a first cavity adjacent a second cavity;
- a bolt moveable within the first cavity between a first position within the first cavity and second position extending out of the first cavity into the path of the sliding window;
- a latch within the second cavity moveable in a direction transverse to said bolt, the latch engaging the bolt in a locked position and removed from engagement with the bolt in an unlocked position;
- an actuator on the latch for moving the latch between its locked and unlocked positions;
- and,
- a means for guiding the bolt between its first and second positions which comprises a tongue and groove arrangement between the bolt and the housing to guide the bolt along its movement and to transfer lateral loads from the bolt to the housing, the bolt receiving the lateral loads from the sliding window contacting the bolt when the bolt is in its second position.
