3 Claims.
and unlocked "'from"*either thefinside or outside by a key.
With the usualfchainiock the door is locked in" a 'predetermined" posltionfand" the area of' the opning'is'fixed. This type of lock is only adapted to" be unlocked from the inside and, therefore, when leaving the'house or apartment, it is necessary" to"compl'etely close, the door. With this thought "in mind? this invention contemplates a latch whereina lock 'bolton a door-or window may be-lockedin notches iii'bars'extending from the frame by-a-lock on" the bars" and thelock may be-opened 'by at key.
The object of this invention is, therefore, to provide an improvedlatch=for-wdoors, windows, and the likethat may readilybe installed on the surface of a door or window, and frame by which a door or sash may be locked in partially open positions and"locked""andunlocked from either the inside or outside of the door or window.
A nother object of theinvention is to; rovide aniim'iroved latchfor dO'IS',-Wifid0WS, and the like by which a door or window may be secured in a partially open. position in which the parts of the latch may be-actuated to-substantially obscure positions when not in use.
A "further object of the invention is to provide an-impi'ovedlatch for lockingdoors, windows; and the like in different selected partially open positions, which is of a simple and economical construction.
With these and other objects and advantages in view the invention consists of the new and novel combination, construction, and arrangement of parts as hereinafter more fully described, set forth in the claims appended hereto, and disclosed in the accompanying drawings forming part hereof, wherein:
Figure 1 is a sectional plan view illustrating the latch in the position of looking a door in a partially open position.
Figure 2 is a similar view showing the door closed.
Figure 3 is a'viewshowing a front elevation of a door inthe position illustrated in Figure 1 with parts broken away.
Figure 4 is a sectional view taken on line 44 of 'Figurel, illustrating the door and latch in elevation.
Figure 5 is a similar view looking toward the edge of a door frame with the dooromitted,
showing thelatch elements open and positioned against the surface of the door frame.
Figure 6 is a vertical section through the mounting base of thelatch showing the :gear segments on thebars, withparts broken-away, and illustrating a modificationwherein: the base is locked in a channel shapedguide.
Figure 7 is a plan view'of the base shown in Figure 6 with the outer ends of the'arms broken away.
Figure 8- isa detailshowing the look bolt on the door illustratinga modification wherein the mounting bracket thereof is hinged.
Figure 9 is aview illustrating thelatch on-a window.
Referring now to the drawingswherein like reference characters denote-corresponding parts the improved door lock of this invention includes parallelbars Ill and [L -a mounting base l2,a lock 13, and a lock bolt I l.
The bars I0 and iiwarenpivotally'mounted in a base 15 on pins iiiand ll; respectively, and the inner edges of theibars.are providedwith notches land [9 in whicnthe'bolti4: is .securedas shown in Figures;3 and 4. \Theinner ends: of the bars are formed withgearsegments 20: and 2| and with the .teethofone segmentmeshing with those of anotherione bar willa move with the other sothatitis: onlyhecessaryto .grip one of the. bars in opening and; closing. the latch.
The'lock i3 is mounted on the bar Ill and this looks in i a". section 22" on the bar I I, so. that: the bars may be locked together over the lock bolt I4 with the bolt held in a pair of notches.
The mounting base 15 is provided with flanges 23 and 24 by which it is secured on the door frame 25 by screws 26 and 21, and the lock bolt i4 is mounted by a bracket 28 on a door 29 by a screw 30.
In the design shown in Figures 6 and 7 bars 3| and 32, similar to the bars I0 and II, are pivotally mounted in a base 33 on pins 34 and 35, and these bars are provided with gear segments 36 and 31 that also mesh so that one bar will move with the other. In this design the bars are provided with arms 38 and 39 that extend through a slot 40 in the base 33 and into a slot 4| in a channel-shaped guide 42, wherein the base 33 with the arms and bars 3| and 32 is locked in the guide when the bars are extended outwardly in the position of locking the lock bolt i4, whereas with the bars 3| and 32 opened, as illustrated in Figure 5, the arms 33 and 39 will be free of the notch or slot 4| so that the base 33 may be slid out of the guide 42. By this means the guide 42 may be mounted upon the door or window frame by the screws 43 and 44 and when the base 33 is inserted the screws will be covered so that the latch may not be removed by a screw driver, when the door or window is locked. In this design the bar 3| is provided with a lock 45 which is mounted thereon by rivets 4B and 41, and a corresponding lock section 48 with a tongue 49 is mounted on the bar 32 by rivets 50 and In the design shown in Figure 8 a lock bolt 52, similar to the bolt I4 is carried by a hinged bracket 53 so that it may be moved to the position shown in dotted lines when not in'use.
In the illustration shown in Figure 9 the latch is mounted on a window with a base 33 mounted on the sill 54, and the bars 3| and 32 looked over a bolt 55 on a sash 56, and it will be understood that the latch may be'used on a window, door, or the like, and located in any suitable position thereon.
When not in use the bars may be opened to positions against the surface of the frame, as shown in Figure 5, so that the parts are substantially out of the way. 7
With the parts arranged in this manner a door or window may be locked in different selected partially open positions and particularly, when used on a door, the door may be unlocked from either the inside or outside. The bolt l4 on the door is positioned in one of the pairs of notches in the bars and the outer end of the bolt may be provided with a head 51 to prevent its being forced through the notches.
What is claimed is:
It will be understood that modifications may be made inthe design or arrangement of the parts without departing from the spirit of the invention.
1. In a latch for looking a door in a partly open position, the combination which comprises a bracket adapted to be attached to a door frame, a pair of bars having gear segments on one of the ends thereof and notches in the meeting edges, means pivotally mounting the bars on the bracket with the gear segments positioned to mesh and with the notches in the meeting edges of the bars positioned in registering relation, a bolt having a mounting bracket on on end, said bracket of the bolt adapted to be attached to a door of the said door frame with the bolt positioned to selectively extend through the said notches in the meeting edges of the bars, and means locking the bars together.
2. In a latch for locking a door in a partly open position, the combination which comprises a bracket adapted to be attached to a door frame, a pair of bars having gear segments on one of the ends thereof and notches in the meeting edges, means pivotally mounting the bars in the bracket with the gear segments positioned to mesh and with the notches in the meeting edges of the bars positioned in registering relation, a bolt having a mounting bracket on one end, said bracket of the bolt adapted to be attached to a door of the said door frame with the bolt positioned to selectively extend through the said notches in the meeting edges of the bars, a lock bolt positioned on one of the bars and a key actuated lock mounted on the other bar and positioned to coact with the lock bolt for securing the bars with the meeting edges thereof together.
3. In a latch for looking a door in a partly open position, the combination which comprises a guide adapted to be attached to a door frame, a bracket slidably mounted in the guide, a pair of bars having gear segments on one of the ends thereof and notches in the meeting edges, means pivotally mounting the bars in the bracket with the gear segments positioned to mesh and with the notches in the meeting edges of the bars positioned in registering relation, arms extended from the ends of bars on which the gear segments are positioned and positioned to extend through the bracket and into'the guide for retaining the bracket in the guide with the bars extended whereby the meeting edges thereof are together,- a bolt having a mounting bracket on one end, said bracket of the bolt adapted to be attached to a door of the said door frame with the bolt positioned to selectively extend through the said notches in the meeting edges of the bars, and means locking the bars together.
