Definitions

  • This invention relates to a coaxial double-barrel lock which can be operated with a tubular key and comprises a bit rotatably supported between the barrels, wherein each barrel includes a hollow cylindrical body and has a cylindrical plug coaxially rotatable within said hollow body and formed with a coaxial cylindrical passageway, wherethrough there extends a stem defining an annular space for the insertion of the key therein, and wherein the hollow body and the cylindrical plug are provided with radial holes or bores intended for accommodating pins and tumblers which, under the action of springs and at a pre-determined position of the cylindrical plug relative to the hollow body, are mutually aligned, and upon insertion of the key, enable the cylindrical plug to be rotated, whereas with the key removed, they rest on said stem.
  • the meeting surface between the pins and tumblers will coincide with the so-called "shear surface” defined by the adjacent cylindrical surfaces of the cylindrical plug and of the body.
  • the key being provided with means adapted for rotary engagement in the cylindrical plug, by turning the key, one is enabled to rotatively entrain the cylindrical plug and accordingly actuate the bit which acts on the latch.
  • Tubular key operated locks are known already, e.g. from U.S. Patent No. 913,942.
  • the increased constructional complexity of such locks over traditional locks using a flat type of key, is compensated for by their greater resistance to burglarious raising and by the higher number of codifications achievable.
  • tubular key locks are only of the one-way type, i.e. one which can only be operated from one side of a door or gate.
  • traditional twin coaxial barrel locks as operated by means of flat keys, are utilized.
  • the bit is carried rotatably between the barrels.
  • This invention sets out to provide a lock having two coaxial barrels which can be operated with a tubular key from either sides.
  • a coaxial double-barrel lock which can be operated with a tubular key and comprises a bit rotatably supported between the barrels, each barrel comprising a hollow cylindrical body and a cylindrical plug coaxially rotatable inside said hollow body and formed with a coaxial cylindrical passageway, wherethrough there extends a stem defining an annular space for the insertion of said tubular key therein, said hollow body and cylindrical plug being provided with radial bores for accommodating pins and tumblers therein, said pins and tumblers, under the action of springs and at a determined position of said cylindrical plug relative to said hollow body, being mutually aligned, and, upon insertion of said tubular key, enabling said cylindrical plug to be rotated, whereas with said tubular key removed, said pins and tumblers rest onto said stem, said lock being characterized in that said stems are rotatively coupled to, but axially slidable in the inside of a respective one of said cylindrical plugs and include
  • the lock in order to afford the possibility of operating the lock from one side even if on the other side a key has been left inserted and turned in the keyhole, the lock is characterized in that one of said portions is normally held in rotary engagement with the bit through a coupling member the opposite ends whereof are inserted into coaxial recesses of said portions such that it is axially rigid but rotatable in one portion and axially slidable in the other portion and rotatively -coupled to the latter by means of radial lugs which extend radially through slots in said portion and rotatively engage the cylindrical plug and the bit opening, between said coupling member and that portion with respect whereto it is axially slidable there intervening a return spring which, with the keys being removed from both sides of the lock, holds the portions outside of the bit opening, whilst to cause one portion to be displaced to the position of engagement with the bit, the key comprises a tubular shank wherein a pin is guided coaxially which is held
  • the lock comprises two barrels la, 1b including cylindrical cases 2a, 2b which are coaxial to each other and have,at the bottom,projections or extensions 3a, 3b.
  • the barrels 1a, 1b are interconnected by an insert 4 having two coaxial shanks 4a, 4b which penetrate two holes 5a, 5b in the projections 3a, 3b and are secured by pins 6a, 6b.
  • the insert 4 is formed with a threaded hole 7 for receiving a screw whereby the lock can be affixed to a door.
  • tubular bodies 8a, 8b which are locked in position by means of pins 9a, 9b, and accommodate cylindrical plugs 10a, 10b for rotation therein.
  • the cylindrical plugs are provided, at their outer ends, with flanges 11a, 11b the peripheries whereof are surrounded by annular portions 12a, 12b of the tubular bodies 8a, 8b.
  • the cylindrical plug ends which lay opposite to the flanges 11a, 11b extend into an opening 13 defined between the barrels 1a, 1b.
  • the cylindrical plugs are retained axially by rings 14a, 14b which engage in annular grooves on the cylindrical plugs themselves and are clamped between the tubular bodies 8a, 8b and inner collars 15a, 15b of the cases 2a, 2b.
  • Coaxial cylindrical passageways 16a, 16b for the introduction of a tubular key are provided lengthwise to the cylindrical plugs.
  • the passageways form, on the side facing the opening 13, cylindrical seats 17a, 17b of larger diameters , wherein portions 18a, 18b in the form of cylindrical bodies are slidable.
  • the portions 18a, 18b are provided externally with longitudinal keys 19a, 19b and with stems 20a, 20b which extend coaxially into the passageways 16a, 16b, thus defining annular key-receiving spaces.
  • the keys 19a, 19b run in longitudinal grooves 21a, 21b of the seats 17a, 17b, thereby the portions 18a, 18b are rotatively rigid with their respective cylindrical plugs but axially slidable therein.
  • the hub 22 has a through opening 24 with the same cross-sectional area as the portions 18a, 18b and such as to enable these portions to engage therewith.
  • a rotary coupling is established between the hub 22 and said portion.
  • the seat 17b also accommodates a spring 25 which acts on the portion 18b and holds it normally engaged in the opening 24.
  • the tubular bodies 8a, 8b and the cylindrical plugs 10a, 10b are provided with radial bores 26a, 26b and 27a, 27b for accommodating the pins 28a, 28b and tumblers 29a, 29b therein.
  • the bores are arranged to lay on angularly equidistant radial planes and such that, with the cylindrical plugs in a determined angular position, the bores or holes in the latter are aligned with the bores in the tubular bodies.
  • the pins 28a, 28b are acted upon by springs 30a, 30b which abut against the inner walls of the cases 2a, 2b, and in the position of alignment of the pins and tumblers, hold the tumblers to rest on the stems 20a, 20b.
  • pin alignment position As can be observed in Figure 1, when the key is not inserted into the keyhole, the pins 28a will intersect the shear surface defined by the adjacent cylindrical surfaces of the cylindrical plugs and tubular bodies. By contrast, when the key is inserted, the meeting surface between the pins and tumblers is coplanar with the shear surface, thereby the cylindrical plugs cannot be rotated. This position of the pins will be simply termed hereinafter "pin alignment position", for simplicity.
  • one set of pins are axially offset with respect to the other sets, such as to allow but one position for the withdrawal of the key, which position will coincide with the position of hindered rotation of the cylindrical plugs by the pins.
  • the tubular key for operating the lock of Figure 1 comprises a tubular shank 31 having its free end 32 tapered and being attached to a grip 33 by means of a pin 34. At the root or base of the shank 31, there is provided a lug 35 for engagement in a notch 36a, 36b of the front flanges 11a, 11b. Aligned notches 37 are formed on the shank which are adapted for receiving the tumblers 29a, 29b in accordance with the code which allows the alignment position between the pins and tumblers.
  • the lock shown operates as follows. Upon insertion of the key into the passageway 16a of the barrel 1a, the key abuts against the outer end of the stem 20a with the bottom 31a of the tubular shank . 31. (The same result could be achieved by arranging for the pointed tip 32 to contact the portion 18a). Thus, an axial displacement is produced of the portion 18a which, by engaging in the opening 24 of the bit hub, causes the portion 18b to move out against the bias of the spring 25.
  • the plates of each pair are preferably axially offset such as to result in an increased thickness of the material to be removed.
  • the shanks 4a, 4b of the insert 4 are formed from a hard material and have there ends pointed such as to deflect the tool bit out of the hole 7 wherein the lock mounting screw is threaded.
  • FIG. 4 illustrates a lock which can be operated from one side even when another key has been left inserted on the other side.
  • a coupling element 38 comprising a cylindrical pin 39, one end whereof is provided with a pair of diametrical wings 40a, 40b and the other end is formed with an annular groove 41.
  • the element 38 is inserted with its opposite ends in recesses 42a, 42b formed coaxially in the portions 18a, 18b, and is axially secured to the portion 18b by a pin 43 engaging in the groove 41 to permit the cylindrical plug 10b to be rotated with respect to the element 38.
  • the wings 40a, 40b are passed through the portion 18a in slotted holes 44a, 44b of the portion 18a and engage in notches 45a, 45b of the cylindrical plug 10a.
  • a spring 46 accommodated in the recess 42a and acting on the element 38, holds the portions 18a, 18b apart,such that neither of them engages in the opening 24 of the hub 22. In that spaced-apart position, the wings 40a, 40b are partly inserted in respective cutouts 47a, 47b of the opening 24.
  • the lock In the inoperative condition, that is with the -key removed, the lock has the portion 18a rotatively coupled to the bit through the element 38.
  • the emergency key differs in that, inside the shank 31, there is guided a pin 48 formed with a collar 49 against which acts a spring 50 accommodated in a seat 51 of the key grip.
  • the spring 50 is more rigid than the spring 46.
  • the key cannot complete its travel of insertion into the passageway 16a to take the position of alignment of the pins which allows the cylindrical plug 10a to be rotated.
  • the pin 48 will yield against the bias of the spring 50, which enables the shank 31 to complete the additional displacement movement as required to realize the alignment of the pins and tumblers.
  • the shank 31 will have a shorter length than the stem 20a.
  • the cylindrical plug 10a can be rotated until the portion 18a faces the opening 24 wherein it will engage under the urge of the spring 50. Similar in principle is the operation of the lock when a key has been left inserted into the barrel la and the emergency key must be introduced into the barrel 1b.
  • the wings 40a,40b allow the bit to remain rotatively locked even when the key is removed.
  • the wings are rotatively associated, in addition to the bit hub, also to the cylindrical plug 10a through the slots 44a, 44b of the portion 18a.
