Definitions
- This invention relates to a single-throw bar lock operating with a conventional cylinder.
- the invention relates to a bar lock operating with a cylinder of Yale profile provided with a DIN cam or similar, in which the bars undergo their maximum travel by a single throw corresponding to a 360 ° rotation of the key.

- bar locks consisting of two toothed plates operated by a cylinder provided with a specially constructed gear wheel.
- One end of said plates engages with said gear wheel while the other end is generally connected to another plate which acts as the bar.
- Said gear wheel on rotation, extends or retracts the two plates along a straight line in opposite directions to each other, with the result that the system lengthens on locking the door, by which the bars engage in the appropriate seats provided in the door posts, and the system shortens on unlocking the door as the bar disengage from said seats.

Abstract
Description
- This invention relates to a single-throw bar lock operating with a conventional cylinder.
- More particularly, the invention relates to a bar lock operating with a cylinder of Yale profile provided with a DIN cam or similar, in which the bars undergo their maximum travel by a single throw corresponding to a 360° rotation of the key.
- Said cylinders are normally available commercially as they are used in normal locks, and thus the bar locks according to the present invention have considerable advantages over currently known bar locks, which require a specially constructed cylinder.
- In this respect, bar locks are currently known consisting of two toothed plates operated by a cylinder provided with a specially constructed gear wheel.
- One end of said plates engages with said gear wheel while the other end is generally connected to another plate which acts as the bar.
- Said gear wheel, on rotation, extends or retracts the two plates along a straight line in opposite directions to each other, with the result that the system lengthens on locking the door, by which the bars engage in the appropriate seats provided in the door posts, and the system shortens on unlocking the door as the bar disengage from said seats.
- This type of bar lock has the serious drawback of operating only with a specially constructed type of cylinder, which is difficult to obtain and replace if faulty.
- In the bar lock disclosed by FR-A 1 190 878 the main gear wheel is outside the two toothed plates and requires supplementary transmission gear wheels in order to operate the toothed plates.
- In accordance with the present invention, we have now discovered a new type of bar lock operating with a conventional cylinder of Yale profile with a DIN cam or similar, which also has the advantage that maximum travel is obtained by a single throw corresponding to a 360° rotation of the key.
- The single-throw bar lock operating with a conventional cylinder according to the present invention comprises two parallel toothed plates, two bars fixed to them, a main gear wheel and an auxiliary gear wheel which are interposed between said toothed plates and engage with them, said main gear wheel being in the form of a ring gear which is incomplete due to the presence of a slot, said auxiliary gear wheel being a complete circular gear wheel and each of said toothed plates having a discontinuity in the toothing by virtue of a recessed portion.
- These and further characteristics and advantages of the bar lock according to the present invention will be more apparent from the detailed description given hereinafter with reference to the relative figures, which show preferred embodiments of the invention by way of non-limiting example.
- Figures 1 to 4 show overal views and details of the bar lock, Figures 5 to 8 illustrate characteristics of the bar lock cover, and Figures 9 to 11 show the main gear wheel.
- With reference to the numerals which indicate the various elements of the figures, the
reference numeral 1 indicates the seat into which the cylinder of Yale type is inserted, and 2 indicates the cylinder protuberance which on turning the key causes themain gear wheel 4 to rotate. - By means of the system comprising the
gear wheel 4 andtoothed plates gear wheel 4 by means of thetoothings 6 and 6', the rotary movement transmitted to thegear wheel 4 by turning the key is transformed into a rectilinear to-and-fro movement of thetoothed plates bars 20 fixed to them, so as to effect locking and unlocking. - The
reference numeral 5 indicates the auxiliary gear wheel which, on rotation, transmits movement from one toothed plate to the other and ensures that the plates move without discontinuity when themain gear wheel 4 is in such a position that theprotuberance 2 lies in theuntoothed recesses 7 and 7' of theplates - Special characteristics of the bar lock according to the present invention are the shape of the
main gear wheel 4 which is shown in detail in Figures 9 to 11 and the shape of thetoothed plates - As can be clearly seen from Figures 9 to 11, the
main gear wheel 4 is in the form of a ring gear which is incomplete due to the presence of theslot 9 designed to house theprotuberance 2. Thereference numeral 10 indicates the surface by which thegear wheel 4 rests against the toothed plate. - In their toothing, the
toothed plates discontinuity recesses 7 and 7' which receive theprotuberance 2 during its rotation, as shown in Figure 2. When theprotuberance 2 is in the position shown in Figure 2, the main gear wheel operates only theplate 8, and the movement of theplate 8 is transmitted to theplate 3 by theauxiliary gear wheel 5. - Two
bars 20 are fixed to the outer ends of the toothed plates either directly or byintermediate plates 16, and on locking the door they engage in the appropriate seats provided in the door posts. - As is apparent from the description and figures, a single throw effected by only one 360° turn of the key causes the
bars 20 to extend by their maximum amount, so making the bar lock according to the present invention extremely advantageous and practical. - A further characteristic of the bar lock according to the present invention shown in Figures 3 to 8 is that two mushroom-
shaped elements 19 fixed to thebars 20 engage, during locking, withslots 23 in twoplates 22 fitted to the inside of thecover 21, so preventing its removal when the lock is in its locked state.
