Definitions

• One object of the invention is to provide a locking device which is capable of locking the easement effectively to the frame at the lower portion of the window as well as at the side or sides thereof in the closed position of the window.
• a further object of the invention is to provide a locking device which may be easily operable by a single handle to efliciently lock the easement to the frame at more than one point.
• the invention has also for its object to provide a locking device with a simple, reliable and durable connecting means for transmitting movements from locking means at the lower portion of the window to locking means at the vertical edge thereof.
• a lock adapted to secure the lower edge of the easement to the frame has a push rod at the lower portion of the window, and that a vertical locking rod adapted to secure the vertical edge of the easement to the frame is movable at the vertical edge of the window, a flexible connecting member such as a chain mounted in an arcuate guide being arranged between the push rod and the vertical locking rod to transmit motion therebetween.
• Fig. 1 is a diagrammatic front elevation of the window in its closed position.
• Fig. 2 is a vertical section of one side of the window, on a larger scale.
• the window is of the type in which a casement I is swingable about a horizontal axis, a lock, preferably a push lock being provided at the lower edge of the window, which look is fitted into the frame 2 of the window in the example shown.
• a handle 3 of the lock is connected with the push rods 4 in any suitable manner, not illustrated, so that said push rods will be displaced outwardly from the handle or inwardly toward the same, according as the handle is swung in the one or the other direction.
• Displaceably arranged in the side pieces of the frame 2 are vertical locking rods 5, the special flexible connecting members according to the invention being arranged between said vertical locking rods 5 and the push rods 4.
• the vertical locking rods 5 each have a pin 5a adapted to engage an oblique slot in a mounting plate 5b secured to the edge of the casement, to lock the top of the easement to the frame 2.
• the connecting member between a, push rod and a vertical looking rod 5 consists of a chain 6 arranged in an arcuate guide I.
• Said guide is constituted by a channel of U-shaped cross section, and is fitted into a recess 8 in the frame, wherein it is suitably secured.
• a link 9 arranged between the push rod 4 and the chain is a link 9 provided with two offset surfaces [0, ll, an abutment l2 or the like on the push rod engaging between said offsets, which are arranged at a distance from each other, so
• the push rod may be displaced for a certain distance independently of the link.
• the window at the lower edge thereof by means of the push look, before the vertical locking rod is actuated.
• a locking device comprising a push rod slidably mounted at the lower portion of the window frame, a vertical locking rod movable at the vertical edge of the window for securing the vertical edge of the casement to the frame, a chain'connected to and for transmitting movement between the push rod and the vertical locking rod, and link having two spaced shoulders and connected to the chain, said push rod having an abutment projecting into the path between said spaced shoulders.
• a locking device comprising a push rod slidably arranged at the lower portion of the window, a vertical locking rod displaceable at REFERENCES CITED the vertical edge of the window for securing the
