The bore has a portion of enlarged diameter and the control element is in the form of a pin disposed in said bore and having a collar (10) freely movable in the enlarged diameter portion thereof between an end face forming the bottom of said portion and a retaining ring (11) arranged at the open end of the bore.
Description
- This invention is concerned with a key for use with a locking device.
- There is described in DE-A 3424307 a locking device comprising a lock of the cylinder type wherein the cylinder has a housing in which a cylinder plug is rotatably accommodated, together with a plurality of tumblers, the plug having a profiled keyway into which said tumblers extend in the rest condition of the cylinder, wherein an additional tumbler is provided which is mounted for sliding movement in a bore the longitudinal axis of which is parallel to but offset from the longitudinal central plane of the keyway, and further wherein an abutment is also provided in the keyway in the region of the additional tumbler but spaced therefrom, the locking device being adapted for use with a key having a profiled blade corresponding to the keyway and having mounted in the blade, for sliding transverse movement therein, a control element which is urged by engagement of one end portion thereof with the abutment into a condition in which an opposite end portion thereof projects outwardly from the key blade, said projecting end portion serving to operate the additional tumbler.
- The additional tumbler (in fact in this case there are two) is movable in its bore through a distance which cannot exceed the heightwise dimension of the control element of the key and indeed in the particular case is movable through a stroke which is substantially smaller than such dimension. In this regard, it has to be considered that for moving the tumbler some form of camming surface or run-up slope has to be provided on the control member and clearly the heightwise distance over which such run-up slope extends cannot exceed the overall height of the control element. What is more, the run-up slope may not exceed a certain angle of inclination if jamming of the key during insertion is to be avoided.
- In the aforementioned specification, therefore, a key is provided comprising a longitudinal groove along one wide face of the key blade.
- More particularly, in order to enhance the stroke through which the additional tumbler is moved, the control element has to be formed as large as possible while the additional tumbler(s) have a diameter as small as possible so as to be accommodated within the lengthwise surface of the control element provided adjacent the run-up slope. To form the additional tumbler thin, however, is disadvantageous in that it affords a weak locking function.
- It is thus an object of the present invention to provide a key for a locking device in which the above disadvantages of the aforementioned disclosure are reduced or substantially avoided.
- It is a further object of the present invention to provide a key for use with a locking device as set out hereinbefore, which key is of simpler construction, requiring less customised parts, than was the case of the key in accordance with DE-A 3424307.
- The present invention, provides a key for use with a locking device comprising a profiled key blade provided with a row of V-cuts on one narrow edge and having a control element accommodated for transverse movement in a bore extending transversely of the key blade and opening into the opposite wide faces thereof, such that when the element is urged, by engagement of one portion thereof, in one direction so that said one end portion lies flush with one of the wide faces of the key blade, an opposite portion thereof projects outwardly beyond the other wide face of the key blade, characterised in that the bore has a portion of enlarged diameter and the control element is in the form of a pin disposed in said bore and having a collar freely movable in the enlarged diameter portion thereof between an end face forming the bottom of said portion and a retaining ring arranged at the open end of the bore.
- Locking devices for use with the key according to the present invention are described and claimed in our co-pending European Patent Application No. 86 303931.9 (Published Application No. 202949) of even date herewith.
- In a key in accordance with the present invention, therefore, the bore has a portion of enlarged diameter and the control element is in the form of a pin disposed in said bore and having a collar freely movable in the enlarged diameter portion thereof between an end face forming the bottom of said portion and a retaining ring arranged at the open end of the bore.
- It will be appreciated that in comparison with the key of the earlier case, a simple pin is now sufficient to actuate the additional tumbler, the pin being of course provided with a collar, which may be integral with the pin, by which, in combination with the bottom of the enlarged bore portion and the retaining ring, the pin is held captive in the bore.
- Moreover, in such a key it is now possible, by the provision of a longitudinal groove along one of the wide faces of the key blade, to provide a pin which does not exceed the transverse dimension of the key blade, this being achieved in that the bore opens into the groove and further in that the length of the pin while it does not exceed the transverse dimension of the key blade, is such that, when the opposite end portion thereof is caused to project outwardly as aforesaid, it extends beyond the outside dimension of the key.
- A significant advantage of the key of the present invention resides in that, because the control element is in the form of a relatively small pin, the handling of the key by the user becomes more commodious and in particular the key does not exhibit projections of the type of the key of the earlier case, which projections are likely to snag in the users pocket or with the users apparel when being carried or handled by the user.
- There now follows a detailed description, to be read with reference to the accompanying drawings, of a key in accordance with the present invention in combination with a locking device. It will be appreciated that the key and locking device have been selected for description merely to illustrate the invention by way of non-limiting example.
- In the accompanying drawings:-
- Fig. 1 is a view of the blade end of a flat key before insertion into a lock cylinder shown in elevation;
- Fig. 2 is a horizontal section, on a very enlarged scale, through the lock cylinder housing and the associated key blade in the region of the control element before the key has been inserted into the hole;
- Fig. 3 is a cross-section, along offset planes, through the lock cylinder when the key is not inserted;
- Fig. 4 is a partial longitudinal section through the lock cylinder in the region of the additional tumbler;
- Fig. 5 is a cross-section corresponding to Fig. 2, but with the key inserted;
- Fig. 6 is a cross-section corresponding to Fig. 3, likewise with the key inserted;
- Fig. 7 is an illustration corresponding to Fig. 4, wherein the additional tumbler is moved by the control pin when the key is inserted; and
- Fig. 8 is a view in perspective, on a very enlarged scale, of the additional tumbler with the control element shown in chain-dot.
- The lock cylinder has a profiled
lock cylinder housing 1, in which acylinder plug 3 is rotatably mounted in alongitudinal bore 2. Theplug 3 is non-rotatably secured to athrower ring 5 having athrower 4. - In the
lock cylinder housing 1 and thecylinder plug 3 are provided, in the longitudinal central plane of the lock cylinder, bores 6,7 which lie in alignment with one another and which receivetumblers 8 comprisingplug pins 8′ and housing pins (or drivers) 8˝. The housing pins are urged outwardly towards thepins 8′ by compression springs 9. - A
keyway 10 of profiled cross-section extends in theplug 3 in the axial longitudinal direction thereof. Thekeyway 10 is adapted to the cross-section of thekey blade 11 of aflat key 12. The one narrow edge of thekey blade 11 is provided with a row of V-cuts 13 of different depths, which cooperate with thetumbler pins 8 and operate them, when the key is inserted, so tha. the joint line between theplug pins 8′ andhousing pins 8˝ lies at the level of the plug rotation line F (see Fig. 6). - The
key blade 11 has profile longitudinal grooves on both wide sides, corresponding to the transverse profiling of the keyway. Acounter-sunk recess 15 extends from the bottom of a central one of the profiledlongitudinal grooves 14, which is wider than the other grooves, and extends almost up to the opposite wide side of the key. At thebottom 16 of the countersink is acentral bore 17 through which thecontrol element 18 in the form of a pin extends. Aretaining ring 19 is disposed at the open end of therecess 15 and serves to guide thecontrol pin 18. Thecontrol pin 18 is restrained in the transverse direction by acentral collar 20, which fixedly projects from the control element and is freely movable between the annular area ofcountersink bottom 16 and theretaining ring 19. The latter is pressed into the key blade and thus ensures the non-releasable mounting of thecontrol element 18. The length of thecontrol element 18 corresponds to the transverse dimension, i.e. thickness of the key blade 11 (see especially Fig. 2). - In a region between two
tumbler pins 8 extends anadditional tumbler 21 which is movable in abore 22 opening into one side of thekeyway 10 and extending parallel to the key insertion plane. More particularly, theadditional tumbler 21 comprises astem 23 andhead 24, the latter being axially offset from thestem 23. The centre point M of thestem 23 is thus at a greater distance from the keyway than thecentre point M 1 of thhead 24. Theadditional tumbler 21 is secured against rotation by guiding thestem 23 in abore section 22′, which is axially offset from abore section 22˝ of larger cross-section in which thehead 24 is movable. The head is flatted on the side facingche keyway 10 so as to lie flush with theside wall 10′ of the keyway. Adjacent the flatted surface is formed a run-up slope 26 which extends up to aside wall portion 25 of the head. The run-up slope 26 increases in the direction of key insertion. Adjacent thebore 22, at the key entry side thereof, and running thereinto, is formed arecess 27 extending into theside wall 10′ of the keyway. A projection or spigot 34 projects from thehead 24 in opposed relationship with thestem 23 and cooperates with a stroke-limiting abutment in the form of apin 35 in-set in the outer surface of thecylinder plug 3. To this end, thecylinder plug 3 has agroove 36 intersecting thebore 22 and running in the longitudinal direction of thecylinder plug 3, the depth of the groove corresponding approximately to the diameter of the stroke-limitingpin 35.Lateral recesses 37 in thegroove 36 ensure the correct location of the stroke-limitingpin 35. - The
stem 23 of theadditional tumbler 21 cooperates with ahousing tumbler 29, which is guided in abore 28 of thelock cylinder housing 1. Thetumbler 29 is secured against rotation as a consequence of its being offset from the longitudinal central plane of the lock cylinder. Thistumbler 29 is also acted upon by a compression spring (not shown) so that, when the key is withdrawn, the position as shown in Fig. 3 pertains, wherein thetumbler 29 projects with its end facing the cylinder plug into thebore section 22′, brings thetumbler 21 into abutment with the stroke-limitingpin 35, and provided additional security against rotation. - In opposed relationship with the
head 24 there extends on the other side of the keyway 10 aslot 30 which lies transversely of the keyway and into which an abutment in the form of aninsert 31 is fixedly inserted. The end of this insert 31 projects into the keyway beyond thecorresponding side wall 10˝ of the keyway. The edge projecting into thekeyway 10 provides asurface 32 for actuating thecontrol element 18, the side of saidsurface 32 facing the keyway insertion direction forming a roof-shaped slope 33. This surface lies at the level of the profiledlongitudinal groove 14 of the key and projects thereinto when the key is inserted. - The distance x between the
side wall 25 of thehead 24 and theopposite surface 32 of theinsert 31 corresponds to the amount y of the dimension extending transversely of thekey 12. - The entry area of the
keyway 10 is provided with funnel-shapedtapering guide surfaces 34 which guide thecontrol element 18, if projecting, into the keyway. - The mode of operation is as follows: When the
flat key 12 is inserted into thekeyway 10, its V-cuts 13 operate thetumbler pins 8. Thecontrol element 18 is guided through the keyway (see chain dotted illustration in Fig. 5). Upon engagement of one end portion of thepin 18 with the roof-shaped slope 33 of theinsert 31, thecontrol element 18 is shifted transversely in the direction of the run-up slope 26 of theadditional tumbler 21. Therecess 27 disposed in front ofslope 33 receives the opposite end portion of thepin 18 during this transverse motion, so that thecontrol element 18 reaches the chain-dotted position in accordance with Fig. 4, but at this stage no shifting of theadditional tumbler 21 has taken place. This position corresponds to the end position of the transverse displacement of thecontrol element 18. When the key is inserted further, the run-up slope 26 is engaged by the end portion of thecontrol element 18 which projects beyond the wide side of the key, and a corresponding downward displacement of the additional tumbler takes place. This downward motion ends when the key has been completely inserted. At this stage thecontrol element 18 is then disposed with its projecting end on the end face of thehead 24, thestem 23 thereof has forced thehousing tumbler 29 out of thecylinder plug 3, and the joint line between theadditional tumbler 21 and thehousing tumbler 29 lies on the plug rotation line, as do also the joint lines between theother tumblers 8 in the longitudinal central plane. Thecylinder plug 3 can then be rotated by means of theflat key 12. After the key has been withdrawn, all the tumblers return to their initial position shown in Fig. 3, thus preventing a rotating movement of theplug 3 inside thelock cylinder housing 1. - It will be appreciated that the diameter of the projecting end portion of the
pin 18 is substantially less than the lengthwise dimension of the run-up 26 formed on the additional tumbler 21 (see e.g. Fig. 7), while the amount by which said projecting end portion projects beyond the wide face of the key 12 is not greater than the transverse dimension of said run-up slope 26 (see e.g. Fig. 6). - It will also be appreciated that the key 12 is made from a key blank exhibiting the longitudinal grooves and the bore with the
pin 18 held captive therein as aforesaid.
