Definitions
- the present invention relates to a locking device according to the preamble of claim 1.
- a locking device of the generic type is known from WO 98/35201 A1 dealing with a firearm safeguard device capable of preventing unauthorized access to the trigger by blocking the trigger.
- This prior art locking device presently locks for slidable doors can be used only in the completely locked position where the door is tightly shut against the door jamb, requiring high precision matching of the contacting surfaces.
- the adjustable locking device for locking a first member to a second member comprises: a male lock member comprising a spindle formed with a first flat friction surface and means for mounting the spindle onto one of the members; a female lock member comprising a prismatic friction member nested within a first cavity formed in the block-like lock member, the cavity having opposite side surfaces configured to support a reciprocating sliding movement of the prismatic friction member thereinside, means for guiding the reciprocating sliding movement of the prismatic friction member, a second cavity formed in the block-like lock member, merging from the first cavity and configured to freely receive the spindle of the male lock member, spring means urging the prismatic friction member in the direction of the second cavity, a second flat friction surface, mating the first friction surface formed at the side of the prismatic friction member facing the second cavity, so that during insertion of the spindle into the second cavity, the first and the second friction surfaces slide one on the other against the
- the invention can be applied to a large range of applications, but is particularly useful for securing sliding doors and windows, and therefore mainly described in that context.
- Block 12 has right and left sides 12a and 12b, and panel side denoted 12c, and is formed with a first, throughgoing rectangular passage 14, merging into a second, mostly circular passage 16.
- a prismatic lock member 18 is freely seated, recipocable in the up and down directions.
- the lock member 18 is provided at its bottom side with a friction surface denoted 18a, which may be of various types -- see Figs. 1c-1e.
- the reciprocating movement of the lock member 18 can be blocked by the operation of a standard push-in lock designated 22, using a key 23 (see Fig. 4), a rotatable cylinder lock (see Fig. 8), or any other suitable key-operated locking devices.
- the counter-part of the female lock member 10, namely the male locking member 24 of Fig. 1b comprises a generally circular spindle-like member 26, being formed with a flat surface 28 bearing thereon a complementary friction surface 28a as will be described below.
- a facet 28b is preferably formed as shown.
- the diameter of the spindle 26 is slightly less than that of the circular passage portion 16 of the female member 12, so as to be freely insertable thereinside.
- the spindle 26 is carried by a mounting bracket generally denoted 30 of any suitable shape which may be changed according to the application of the locking device (e.g. see Fig. 12).
- the bracket 30 is provided with mounting legs 32a and 32b with suitable screw openings as shown.
- the spindle 26 may be pivotally mounted to the bracket 30 e.g. by a pin 34.
- the reciprocable friction member 18 is held between walls 14a and 14b of the rectangular passage 14 in a freely slidable manner, guiding means being provided in the form of at least one -- but preferably two -- guide pins 40a and 40b (Fig. 3), passing through guide slots 42a and 42b, respectively, for allowing a limited up and down movement of the friction member 18.
- the friction member 18 In the non-operative position shown in Fig. 2, the friction member 18 is urged by one or more springs 44 pushing from above so that the friction surface 18a bulges or projects into the circular passage portion 16.
- the spring 44 may be installed and supported by press-fit insert pin 45 as shown.
- the friction member 18 is further formed with a bore 46, of such location and size as to cooperate with the push-in lock device 22 (or equivalent thereof -- see Figs. 8 and 9) which is installed as shown.
- the mating friction surfaces 18a and 28a may take several forms.
- the surfaces are simply zig-zaged;
- Fig. 1d there is provided one (or more) rounded rib, adapted to snap into any of the series of grooves constituting the friction surface 28a; and
- Fig. 1e shows the reverse arrangement.
- Fig. 4 presenting the operative, locked position of the device, the insertion of the spindle 26 into the passage 16 will cause the frictional engagement of the surfaces 18a and 28a, while the member 18 clicks up and down over the friction surface 28 of the spindle 26, and against the bias of the spring 44.
- a locking position is attainable by pushing the locking detent 22a of the push-in lock 22 into the bore 46 of the friction member 18. This arresting or fixation will prevent further insertion or, more importantly, retrieval of the spindle 26, since the frictional movement of the friction member 18 over the spindle 26 will be blocked.
- a slide door (or window) generally denoted D is closable against jamb J.
- the female locking device generally denoted 110 is mounted to a side frame member F1 of the door D, whereas the male member 124 is mounted to frame member F2 as clearly seen in Fig. 6.
- the female member 110 is mounted by screws fitting into suitable bores formed in the block-like casing 112 of the female member 110 and the male member is mounted by screws as shown in Fig. 6.
- Fig. 7 The unique feature achieved by the locking device of the present invention is vividly illustrated in Fig. 7, namely that an intermediate locking position is attained where a gap L is left between the door D and door jamb J for the free flow of air in-between even though the locking device is in its locked position protecting against unauthorized, forceful intrusion.
- the push-in lock 22 is replaced by a common, cylinder-type, eccenter-pin mechanism.
- the off-center pin 222a of the lock 222 through rotation by the key 223, changes its location from the operative, locking position shown in Fig. 8, where the female lock member 118 is locked by the friction engagement with the spindle 226, into an unlocked position by rotating the pin 222a by 180° (shown in dashed-lines in Fig. 9).
- a lap-top computer generally denoted 300 with female locking member 310 and male locking member 324 mounted at the base and cover of the computer, respectively.
- the female, block-shaped member 312 is mounted by a base plate 350, and the male member -- by a base plate 352.
- the spindle 326 may form an anchor for tying the computer to an immovable object 354, against theft thereof, by a cable 356.
- the male friction member 424 comprises spindle 426 which is detachable from the cover of the computer 400. This will enable the use of safety cable 456 also when the computer is in its operative, open-cover position.
