Abstract
Description
- The present invention relates to keys and to key blanks for cylinder locks of the type comprising:
- a head;
- a substantially elongated and flattened body connected to the head and having two opposite main faces, at least one of which is configured for co-operating with elements of the cylinder lock;
- a first engagement member and a second engagement member, which are provided for co-operating with elements of the cylinder lock and are movable, within holes formed through said body and giving out onto said main faces, each between a position where it projects from a respective main face and a position where it is retracted within the respective hole; and
- spring means provided within said body that push said first and second engagement members towards positions where they project from said main faces.
- Keys and key blanks of the type referred to above have been known and used for some time. A recent example of a key of this type is described in the document No.
WO 2009/147660 A2 . - The object of the present invention is to provide a key (and likewise a key blank) of the type referred to above that will be simple and fast to produce and assemble, will be functional in use, and will guarantee a high degree of safety also as regards duplication of the key.
- With a view to achieving the above object, the subject of the invention is a key or key blank having all the characteristics that have been referred to at the start and further characterized in that the aforesaid spring means push the aforesaid first and second engagement members via a third control member, which is movable within said body in a longitudinal direction of said body and is pushed by said spring means towards a position in which it sets itself between said first and second engagement members in such a way as to keep them in positions where they project.
- In the preferred embodiment, the aforesaid control member is mounted within an axial cavity of the aforesaid body formed starting from an end surface of the body opposite to the head of the key or of the key blank. Preferably, moreover, the aforesaid spring means are constituted by a helical spring provided within the aforesaid axial cavity, between the bottom of the cavity and the aforesaid control member.
- Once again in the case of the preferred embodiment, the aforesaid first and second engagement members and the aforesaid control member are balls, even though there is not ruled out the possibility of said members having a different conformation. In particular, in the preferred embodiment, the aforesaid engagement members and the control member are balls of identical diameter.
- According to a further characteristic, the body of the key or of the key blank is provided for defining arrest surfaces for the aforesaid first and second engagement members towards positions where they project. In one embodiment, the hole in which one of the two engagement members is movable gives out onto the respective main face with a conical portion, which defines the arrest surface for the aforesaid engagement member, whilst the rim of the other hole is permanently deformed (the material of the key is metal) for defining the arrest surface of the other engagement member.
- Thanks to the above characteristics, the key of the invention guarantees an operation that is more efficient and reliable as compared to known solutions. The two engagement members are independent of one another, but notwithstanding this they are forced by the control member always to present a symmetrical movement, which prevents any of said members from displacing between the retracted position and the projecting position, unless the other member can perform a corresponding movement. Moreover, a duplication of the key can be obtained only starting from a key blank that is provided with the aforesaid elements, which guarantees the possibility of setting up a system for control of duplications through the provision of authorized centres that are provided with said key blanks.
- Further characteristics and advantages of the invention will emerge from the ensuing description, with reference to the annexed drawings, which are provided purely by way of non-limiting example and in which:
-
Figure 1 is a schematic perspective view of a preferred embodiment of a key according to the invention; -
Figure 2 is a side view of a cylinder lock and of the key ofFigure 1 that can be used in co-operation with said lock, with the key in the condition where it is extracted from the lock; -
Figure 3 is a cross-sectional view according to the line III-III ofFigure 2 ; -
Figure 4 is a cross-sectional view and at an enlarged scale of the detail designated by IV inFigure 2 ; -
Figures 5-7 are views corresponding to those ofFigures 2-4 , which refer to a condition in which the key is only partially introduced into the lock,Figure 6 being a cross-sectional view according to the line VI ofFigure 5 and Figure 7 , showing at an enlarged scale a cross section of the detail designated by VII inFigure 5 ; and -
Figures 8-10 are views corresponding to those ofFigures 2-4 and5-7 that refer to the condition in which the key is completely introduced into the lock,Figure 9 illustrating a cross-sectional view according to the line IX-IX ofFigure 8, and Figure 10 showing at an enlarged scale a cross-sectional view of the detail indicated by X inFigure 8 . - With reference to
Figure 1 , thereference number 1 designates as a whole a preferred embodiment of a key according to the invention. Thekey 1 has ahead 2 and an elongated andflattened body 3 connected at one end to thehead 2 and having two oppositemain faces cylinder lock 4. Thebody 3 has twolongitudinal sides end surface 35. - According to a technique in itself known, both the
main faces sides EP 1 019 601 B1 - In the ensuing description, and in the annexed drawings, the constructional details regarding the cylinder lock, as well as those regarding the surfaces, cavities, and/or grooves provided on the key for co-operating with the elements of the lock are not described or illustrated both in so far as they can be obtained in any known way and in so far as elimination of the majority of the aforesaid details from the drawings renders the latter more readily and easily understandable. For this reason, in the drawings only the main parts of the lock and of the key have been illustrated, as well as the elements of the lock that co-operate with the parts of the key that form the subject of the present invention.
- In the example illustrated in the drawings, the
lock 4 is of the type comprising a body including a pair ofstators respective rotors 50, designed to be driven on the opposite sides of a door on which the lock is mounted. Of course, the above example does not have any limiting value since the key of the invention could be used with any type of cylinder lock, with single or double cylinder. In a way in itself conventional, in the case of the example illustrated, thebody 4 includes anintermediate bridge portion 43 provided with a threadedhole 44 for engagement of a screw (not illustrated) designed to fix the body of the lock within the structure of the door. The drawings do not show the pawl (or cogwheel cam) for governing the lock of the door that is fixed in rotation with respect to therotors 50 and is provided in thespace 45 that separates the tworotors - With reference in particular to
Figure 3 , eachrotor 50 has apassage 51 for introduction of thekey 1. Facing thepassage 51 is apin 60 designed to co-operate with the key, which is slidably mounted in ahole 61 of therotor 50 and cooperates with acounterpin 62 slidably mounted in ahole 63 of thebody 42 of the stator. Thehole 63 is closed at its bottom end by aplug 64 and contains inside it ahelical spring 65 that is set between theplug 64 and thecounterpin 62 so as to push thepin 60, via the counterpin 62 (in the neutral position of therotor 50 that is represented in the drawings) towards an end-of-travel position, in which ahead 60a of thepin 60 comes to bear upon a shoulder defined by an end portion of widened diameter of thehole 61. - With reference now in particular to
Figures 4 ,7 , and10 , the key according to the invention comprises afirst engagement member 301 and asecond engagement member 302, each of which is designed to co-operate with thepin 60 carried by therotor 50, according to the direction of introduction of the key. The twoengagement members main faces helical spring 303. Thehelical spring 303 pushes the twoengagement members third control member 304. - With reference to
Figure 4 , thespring 303 pushes thecontrol member 304 towards a position in which thecontrol member 304 sets itself between the first andsecond engagement members - The
control member 304 is movable in the longitudinal direction of thebody 3 of the key within anaxial cavity 305 obtained starting from theend surface 35 of the key. Thehelical spring 303 is set between the bottom of theaxial cavity 305 and thethird control member 304 so as to push thecontrol member 304 in the longitudinal direction, towards theend 35 of the key, so as to wedge between the twoengagement members - The two
engagement members holes main faces axial cavity 305. - Preferably, the two
holes hole 307 that gives out onto themain face 32. In this way, the above conical rim constitutes a surface for arresting movement of theengagement member 302 towards its position where it projects from themain face 32. On the other side of the key, the rim of thehole 306 facing themain face 31 is deformed permanently (thanks to the malleability of the metal material constituting the body of the key) so as to obtain also on the aforesaid side a contrast surface for the movement of theengagement member 301 towards its projecting position. -
Figures 2-4 show thelock 4 and thekey 1 in the condition in which they are before the key is introduced into the lock. On the key, theengagement members main faces helical spring 303 via thecontrol member 304. In the lock, thepin 60 is held by thespring 65, via thecounterpin 62, in its end-of-travel position (Figure 3 ) in which thecounterpin 62 extends partially within the mouth with widened diameter of thehole 61 so as to prevent any rotation of therotor 50. Of course, in this condition, rotation of therotor 50 is prevented also by all the further control elements with which the lock is provided and which, as has been mentioned above, are not described and illustrated in detail herein. - During introduction of the key into the lock (
Figures 5-7 ), the opposite walls of thecavity 51 force theengagement members respective openings cavity 305, causing thecontrol member 304 to recede towards the bottom of thecavity 305 accordingly, compressing the helical spring 303 (Figure 7 ). As may be seen, in the case of the embodiment illustrated herein, the above condition brings the twoengagement members - When the key reaches the position where it is completely introduced into the
cavity 51 of the lock, one of the twoengagement members pin 60 and can push it into the position illustrated inFigure 9 , as a result of the thrust exerted by thespring 303 via thecontrol member 304. In said condition, the action of thespring 303 overcomes that of thespring 65. At the same time the other engagement member can also move into its projecting position, in so far as it comes to occupy a position corresponding to atransverse groove 500 obtained in the wall of thecavity 51 that faces the one in which thehole 61 is formed. The above condition is clearly visible inFigures 9 and 10 . In this condition, rotation of therotor 50 is enabled in so far as the co-operating surfaces of thepin 60 andcounterpin 62 are exactly on the outer circumferential profile of the cross section of therotor 50. In this condition, the further cavities and/or grooves provided on the key co-operate with the further control elements of the lock (not illustrated) to enable rotation of the rotor, according to any known solution. - When the key is again extracted, the
pin 60 and thecounterpin 62 return into the resting position illustrated inFigure 3 , whilst theengagement members control member 304 return temporarily into the retracted positions visible inFigure 7 until the key is completely extracted from the lock. With the key in the extracted condition, theengagement members control member 304 return into the projecting positions illustrated inFigures 4 and10 . - As may be seen, thanks to the aforesaid characteristics, the key of the invention guarantees a more efficient and reliable operation as compared to known solutions. The two engagement members are independent of one another, but notwithstanding this are forced by the control member to present always a symmetrical movement, which prevents any of said members from displacing between the retracted position and the projecting position, unless the other member can perform a corresponding movement.
- As already mentioned, the invention is also aimed at a key blank having the characteristics defined in
claim 1 and described above. Basically, an example of embodiment of the key blank can be understood as the key illustrated inFigure 1 , with thecavity 305 and theholes engagement members control member 304, and thespring 303, but without all the surfaces, grooves, and cavities that transform the blank into a key suited to operating on a given lock. - Of course, without prejudice to the principle of the invention, the details of construction and the embodiments may vary widely with respect to what has been described and illustrated purely by way of example, without thereby departing from the scope of the present invention as defined by the appended claims.
- For example, the
engagement members control member 304 could have a conformation different from the spherical conformation illustrated above. For instance, theengagement members control member 304. Once again alternatively, themembers respective holes control member 304 could have any conformation, with a wedge-shaped end co-operating with inclined plane surfaces of theengagement members - Also in the case of spherical conformation of the
members member 304 could be constituted by a ball of a diameter different from that of theballs balls axial cavity 305 of the key there may be provided a closing plug. - Moreover, the
cavity 305 might not give out onto the end surface of the key and may be obtained, instead, starting from a side of the key. According to a further variant, thespring 303 is not set between themember 304 and the bottom of thecavity 305, but rather is located on the opposite side of themember 304, for example between the latter and a plug inserted into the end of thecavity 305, in the case where the cavity gives out onto theend 35 of the key. In the case where thecavity 305 is obtained starting from a side of the key, thespring 303 could be set indifferently on one side or on the other of themember 304, between the latter and a corresponding end of the cavity. - As emerges clearly from the foregoing description, the key according to the invention is characterized in that the spring means 303 push the
engagement members third control member 304 that moves along the longitudinal axis of the key. - As already mentioned, the invention must be considered both with reference to a key already formed with its surfaces, cavities, and/or grooves for co-operating with the control elements of a specific lock, and with reference to a simple key blank.
