(01. 292-470) The present invention refers to mechanisms for operating latches used on doors, windows or the like, and which latches are applied independent or in combination with locks of the'usual type.
the latch is effected'by on a knob that projects or the like, the's'aid According to this invention, the operation of direct pressure exerted laterally from the door knob ending at its internal end with an inclined surface that rests on a member connected to the latch. By means of this disposition, pressing the knobinwardly, the inclined surface forces the the latch rearwardly, thus the latch as well as member connected to unlatching the door or window. A proper spring presses, continuously, to return the latch to its normal or closed position.
This type of knob may the like, working always both sides of the door or upon the same member be applied at one or connected to the latch.
Moreover, the knob may be mounted as projecting from a small handle like, for facilitating an Besides, means have fixed'to the door or the easy, operation thereof. been also provided for the pushing knob to be stopped in position with a slight rotary movement for stopping the movement of the latch.
For the purpose that the invention be clearly understood and easily carried into practice, the
same has been illustrated in drawings, in which:
Fig. 1 is a side view of a lock.
Fig. 2 is a perspective pressing against the lat Fig. 3 is a transverse sectional view of the door 7 the accompanying the latch combined with detail view of the knob ch.
with the elements applied and in the locking position.
Fig. 4 is a view similarto the f'orrnenwith the knob in the pressed moved backwards.
Fig. 5 is a transverse right angles to the position and the latch sectional view taken at plane of Fig. 3.
Fig. 6 is a fragmentary sectional elevation dein the operation of fixed to the latch, when Fig. '7 is a similar view in the position subsequent to the half turn having been accomplished these figures Referring to casing I having slidably there is provided a mounted therein a latch 2 the inner end of which is bifurcated to provide arms 3 and 4 whic 5 and 6 on the casing;
h travel between guides the latch being main.-
knob cannot go back, the
, movement.
tained' in the position shownin Figure 1 by the action of a spring I.
Between the ends small roller 8,freely respectively, on the inner ends of the shanksof the knobs I I and l I. Said knobs are. housed inside tubularhandles such as l2, that are applied against the lateral surfaces of the doors, and
each of which have an extension l3. provided with threads M, the threaded extensions being arranged within the corresponding internal cavity 15 provided in the door, and engaged with'th'e'adjacent threaded washer 16 thus fixing securely .knob towards the exterior.
On one of the knobs-that remaining on the internal side of the door or 2!, which both are intended for limiting the movement of the knob and, at the same time, of the knob.
of arms 3 and 4 there is'a mounted on-a pin' 9, upon which rests the inclined surfaces 0 and H1 made,
window-there is a for producing the arrest The operation of the device is very simple. -In
Figure 3 the latch is shown projecting from the front 22 of the casing and engaged in the keeper 23 provided on the door jamb or the like. When pushing, knob H, its inclined end It! will press this back and also, obviously, the latch as seen in Figure 4, leaving the door free to be opened. On releasing the knob, spring l9 pushes it back and the latter returns to its normal position by the action of spring I.
When it is desired to fix the latch in the closed position, it is necessary to rotate the knob, and the'steps of rotation havebeen illustrated in Figures 5, 6 and 'I.
in Figurefi, same has been turn while stop 2| has been 20. In Figure '7 the knob a turn and during this rorotated a quarter of. a displaced within slot appears turned half tation it has been a little for the purpose that stop 2| may. follow angle 24 of the slot and be applied against face 25, so that even when spring 19 is operated, the end thereof remaining behind roller 8, thus locking the latch bolt against On dotted linein'Figure 3 can be seen the position of inclined surface It after rotation of the knob,
In Figure 5, the knob is in,
necessary to advance the same v to provide spaced'arms,
As it has been said before, this latch operating device may be combined with a lock in the form indicated in Figure 1. For that object, the latch is provided with a projection 28, at the rear end of which may advance a piece 27 that operates through the operation of a usual lock device of the simple type or of the drum type, that is applied as shown at 28. Once said piece 21 has been advanced, as illustrated in dotted lines at 21', the latch will be prevented from moving and the door or the like will be kept closed.
Having now particularly described and ascertained the nature of this invention and how same can be carried into practice, I declare that what I claim is:
1. Improvements in mechanisms for operating latches for doors, Windows and the like applied independently or in combination with common locks including a casing, a latch slidably mounted therein and having the inner portion bifurcated a roller journalled vertically between the arms, at least one tubular handle fixed to the side of the door and positioned laterally of the casing, a knob having its inner shank portion reduced and slidably and rotatably arranged in the handle and having its extreme inner end inclined for direct engagement with the roller on the latch so that on pushing the rod inwardly the inclined surface contacts the rollers and imparts an inward sliding to the latch to retract the latter, a spring arranged about the shank portion of the knob and within the handle for normally holding the handle in an extended position, and co-operative means on the handle and inner shank portion of the knob for guiding the shank portion during the half turn of the knob and a locking of the inclined face in the rear of the roller to prevent at times operation of the latch.
2. Improvements in mechanisms for operating latches as claimed in claim 1, in which two handle and knob arrangements are provided and located on opposite sides of the door, and the cooperative means being arranged on the handle and knob that are positioned on the inner side of the door.
3. Improvements in mechanisms for operating latches in accordance with claim 1 in which the knob is provided with a longitudinal slot which near the inner end of the knob is extended transversely of the knob and is provided with an angular terminal portion, a fixed stop on the body of the handle and engaged in said longitudinal slot for guiding and limiting the movement of the knob, said stop being engageable with the angular terminal of the slot subsequent to passing through the transverse portion of the slot on the turning of the knob to thereby prevent lengthwise movement of the knob, the knob when engaged in the angular terminal portion having its inclined end situated behind the roller fixed to the latch thus also preventing the latch from return movement for opening the door or a the like.
