A locking arrangement of the kind in which an actuating gear is mounted on the cylinder of a cylinder lock and is adapted, when turned by a key, to actuate at least two locking bolts into locking or unlocking position through the inter-mediary of curved links pivotted to a toothed wheel with which the actuating gear is meshed, characterized in that a spring-biassed latch is provided which in the unlocked position of the locking bolt is adapted to be operatively connected to the handle or to a second toothed wheel actuated by the cylinder lock in order to withdrawn.
Description
- l - 10~53~3 The present invention concerns locks of the type in which an actuating gear is mounted on the cylinder of a cylinder lock and is adapted, when turned by the key, to actuate at least two locking bolts into locking or unlocking position through the intermediary of curved links pivoted to a toothed wheel with which said gear is meshed.
This type of lock will hereinafter be designated as a lock of the kind defined.
There is known a locking arrangement for doors and the like which comprises, in addition to the known latch bolt which is actuated by either the handle or any cylinder lock, at least one elongated locking bolt at an angle to said latch bolt and adapted to engage a side of the door opening other than that which the latch bolt engages, said locking bolt and said latch bolt being connected by means of curved links to a toothed wheel rotatable by an actuating gear, said gear being keyed on the cylinder of said cylinder lock, and being rotated therewith to lock the bolts.
It is the object of the present application to improve said locking arrangement, providing in addition to a locking bolt on the side of the door opposite to that where the hinge is lo-cated, a separate latch which may be actuated by the cylindrical lock or by the handle of the door when the locking bolt is retracted.
10~5;~3 In this manner a more secure locking of the door will be assured, and furthermore when the cylindrical lock is in the unlocking position, the door may be opened from the inside by means of the handle or by actuating the cylindrical lock.
The invention consists in a locking arrangement of the kind in which an actuating gear is mounted on the cylinder of a cylinder lock and is adapted, when turned by the key, to actuate at least two locking bolts into locking or unlocking position through the intermediary of curved links pivoted to a toothed wheel with which said gear is meshed, characterized in that a spring-biassed latch is provided which in the unlocked position of the locking bolts is adapted to be alternatively operatively connected to the handle of the door or to a second toothed wheel actuated by said cylinder lock in order to be withdrawn.
The invention is illustrated, by way of example only, in the accompanying drawings, in which:
Fig. 1 shows an elevational view of the part of the locking arrangement which is destined to face the outside of a door in locking position.
Fig. 2 shows a similar view, in mirror symmetry, of the part of the locking arrangement which is destined to face the inside of a door.
Fig. 3 is an elevation of the side ledge of the locking arrangement at the longitudinal side of the door.
Fig. 4 is a view similar to that of Fig. 1, showing the arrangement in unlocked position.........................
10~5~3 Fig. 5 is a view ~imilar to that of Fig. 2 and in mirror symmetry to Fig. 40 Fig. 6 is an elevation ~imilar to that of Fig. 3.
Fig. 7 is a view similar to Fig. 5, illustrating the operation o~ the latch by the handle.
The lockin~ arrangement compri~e~ a houslng made of two part~, part l facing the outAide Or a door (not ~bown), part 2 facing the in~ide. Throug~h housine part l a handle shart 3 bias~ed by a spring arrangement 4, as known per se, extend~ as well as a keyhole 5 of a cylindrical lock generally indicated by 6. Through housing part 2 only keyhole 5' e~tend~.
The key (nnt shown) in~erted into keyhole 5 or 5 ~rom either side Or the door rotates the cylinder 7 o~
lock 6. nn said cylinder an actuating gear 8 i9 keyed which is in mesh with two registering toothed wheel~
9 Rnd lO mounted on ~haft ll. ~oth wheels 9 and lO
are provided with teeth over part of their periphery, the teeth being substantially in register as will hereinafter be explained in greater detail. To wheel 9 the inner ends four curved links 12 are pivotally mcunted at 13, at equal angular spacings~ To the outo~ ends of links 12 three ~lotted linking bars 14 are pivotally mounted at 15, their outer end~ being pi~otally attached at 16 in locking bar~ 17.
The three locking bars 17 extend to the three side~ o~
the ~oor, i.e. the top, bottom and the longitudinal side _ 4 _ lO~S~tj3 on which the door i~ hlnged, while a fourth ~lotted linking bar 14a extends to the side opposite to the hinged side and i9 sllbAtantially in the form of a triangle having three ~hort bolts 18 integrally mounted thereto and extending therefrom~ Link 14a may, if desired, be ~haped like llnks 14, and may be connected to one bolt only, or, if desired, link 14a may have one or two bo1ts mounted only thereto.
Guides 19, w~lich guide the movement of bars 17, and, at the same time~ act as ~pacer-~ between the two parts of the housing, are provided. Toothed whecl 9 i8 provided at its periphery with two cam depressions 20 which are adapted to be enea~ed by a cam foll.ower 21 Dn~~d mounted on an arm 22 ~Le-~ at 23 and urged by a ~pring 24 into depression-eneaging position. The distance between the two depression~ 20 corresponds to the llmit~ of the angular movement of wheel 9. The teeth of wheel 9 are cut away at 25, so that only the teeth o~ tooth ~heel 10 extend above thls cut-away portion for a purpose which will become clear herein-~fter. It can bo ~een from Figo. 1 and 4 that as cylinder 7 iq rotated tooth ~heel 9 will rotate like-wioe and will actuate locking bolts 18 lnto locking or unlocking positlon, roller 22 engaging in depres~ion 20 in the locking pooition and in depres~ion 20' in the ~locking po~ition. Wheel 10 i9 1ikewise provided wlth a depression 20 of the same 3i~e as that of wheel 9 and with a depression 26 which i~ longer than depression 20'.
_ 5 _1 ~ ~ 5 ~ ~ ~
Wheel 9 furthermore.is provided with annular ~lot~ 27 through which pivot~ 13 e~tend, so that wheel 10 can rotate ~lightly relative wheel 9~
According to the invention a latch 28 is provided which i~, as known per ~e, bia~sed towards locking position by a spring 29, two ~hort spring6 30 being provided to pe~mit the withdrawal of the latch to permit it to be turned over to be u~ed for either left-hand or right-hand door opening~, as known per ~e.
Latch 28 i~ mounted at the end o~ a bolt 31 whlch extends through a mounting plate 32 against which ~pring 29 abuts 9 and ha-~ at ~ts end a stop 33 attached thereto.
The upper end Or a le~er 34 e~tendinB upwardly from an operating member 35 engages bolt 31 between plate 32 pi~lotel E and stop 33~ Member 35 1~ tt~ at 36 to the houJing and i8 provided with a nose 37 adJacent wheel 10.
On wheel 10 a lug 38 is mounted which is adapted to enKage no~e 37 of operating member 35 as will herein-after be explained. Operating member 35 i~ likewise provided with a window 39 into which engages a nose 40 ot~d at one end of a link 41 which is ~ to the housing at 42~ a lug 43 at the other end Or link 41 being adapted to engage a no~e 44 on a plate 4~ integral wlth handle Jhart 3.
The locking arrangement work~ ollow~:
As has been de~cribed with relation to wheel 9, wheel 10 is turned together therewith to achieve a locking po~ition a~ shown in Figs. 1 - 3. ~hen the lock ;53 _ 6 _ i8 turned into unlocking position ~hown in Figs. 4-6 wheol 10 will rot~te together with wheel 9. However, upon further turning gear 8, wheel 9 will remain in place because gear 8 will have ceased to be in me~h therewith owing to cut-away teeth 25, but wheel 10 will rotate further ~ince its teeth are in meeh with gear 8. This further rotation, which is relative to wheel 9, i~ possible owing to slots 27 and depre~sion 26 and causes lug 38 to engage nose 37 of member 35 whereby lever arm 34 retract~ latch 28. Thi~ position is shown in Fig. 7. If, however, in the position shown in Fig. 5 handle shaft 3 i~ actuated, nose 44 will engage lug 43 and cause link 21 to pivot Operating member 34, ~o that latch 28 can be retracted by the handle shaft 30 The lin~ 41 may be operatively connected directly with the bolt 31 of the latch, if de.~ired~
This type of lock will hereinafter be designated as a lock of the kind defined.
