Definitions
- the present invention relates to a safety lock with an adjustable-length bolt. More particularly, the lock in question is intended to be advantageously mounted on doors, main entrances, gates or the like so as to perform closing thereof against a fixed frame of a casing.
- These locks are generally composed, as is known, of a box-shaped body normally made of metallic material and intended to form the structure for supporting and containing the locks, inside which the bolt movement mechanisms are housed.
- the latter can normally be operated from the outside on one side or both sides of the door by means of a key performing one or more turns.
- the box-shaped body is fixed in a seat provided inside a special recess in the door, normally by means of screws, and has a front plate provided with a through- hole for receiving the bolt .
- the bolt is able to slide inside the through-hole between a retracted position, where it is partially (or totally) housed inside the box-shaped body, and a projecting position, where it extends outside the front plate so as to engage inside a corresponding seat provided inside the upright.
- the bolt may extend from the front plate with its extending portion by a variable amount depending on the specific applicational requirements. The latter may include the need to ensure a greater or smaller penetration of the bolt into the seat of the frame or may depend on the specific constructional forms of the door or gate on which the lock must be mounted, which, as is known, in certain cases may require the use of longer or shorter bolts.
- the main object of the present invention is therefore that of overcoming the drawbacks of the solutions of the known type mentioned above, by providing a safety lock with an adjustable-length bolt which is constructionally simple and inexpensive to manufacture and operationally entirely reliable.
- a further object of the present invention is that of providing a lock which allows the adjustment of the projecting portion of the bolt without having to extract the lock from its housing and by exclusively operating on the outside of the box-shaped body containing the lock.
- a further object of the present invention is that of providing a lock, the components of which are easy to manufacture by means of simple mechanical machining processes.
- the safety lock which comprises: a box-shaped body defined by at least one support base and by a front plate; a bolt mounted slidably on the box-shaped body in the direction of its longitudinal axis; actuating means able to move the bolt in the longitudinal direction between different operating positions; a movable element provided with engaging means intended to engage in seats provided along the bolt so as to retain the latter in the operating positions.
- the lock is characterized in that it comprises adjustment means which are accessible from the outside of the box-shaped body and are able to actuate the movable element producing a displacement thereof having at least one rotary component so as to engage/disengage the engaging means in/from the seats.
- Figure 1 shows schematically an overall perspective view of an example of a lock according to the invention
- Figure 2 shows a further example of a lock according to the invention with some parts removed so that other parts may be seen more clearly;
- FIG. 3 shows a front view of the lock according to Fig. 2 with key-type actuating means inserted;
- FIG. 4 shows a perspective view of an enlarged detail of the lock according to Fig. 2;
- FIG. 5 shows three enlarged details of the lock according to Fig. 2, relating respectively to a box-shaped body, to a bolt and to a movable plate;
- FIG. 8a and 8b show two plan views, from two opposite sides, of the movable plate.
- Said lock is suitable for mounting on doors, gates or the like so as to close the latter against a fixed frame, for example consisting of an upright of a casing, not shown in the accompanying drawings because of a type known per se.
- the lock comprises traditionally a box-shaped body 2 made of rigid - generally metallic - material and having a support base 3 from which a front plate 4 extends perpendicularly.
- the said box-shaped body 2 is intended to support also a handle, arranged on one side or on both sides of the box-shaped body 2, or also a latch which can be actuated preferably by means of the said handle .
- the lock 1 also comprises a bolt 5 mounted slidably on the box-shaped body 2 by means of a support guide 6 and a shaped hole 7 formed on the front plate 4.
- the bolt 5 is displaced by means of actuating means 8 between one or more operating positions including generally one or more projecting positions 9 (depending on the number of turns imparted by the actuating means) and a retracted position 10.
- actuating means 8 In this way, it is engaged with and disengaged from a corresponding matching seat formed in the fixed frame, so as to perform the secure closure of a door or a gate against the said frame or so as to release the said door or the said gate, allowing opening thereof.
- the bolt may vary its position also as a result of a different adjustment which will cause it to extend from the front plate 4 with a longer or shorter portion 5a.
- the bolt 5 may disappear completely inside the box-shaped body 2 when it is located in the retracted position 10 and during a particular adjustment condition.
- the abovementioned actuating means 8 are of a type conventional per se and are for example formed in accordance with the example contained in the accompanying figures by a cylinder-type actuator provided with a keyhole 11 for insertion of a key not shown.
- the latter rotating in the keyhole 11, causes rotation of a cylindrical block 50 inside a lining drum 51.
- the block 50 is provided with an associated projection 12 able to engage inside a set of teeth 13 formed by means of incisions along the bottom part of the bolt 5 so as to cause axial sliding thereof along its longitudinal axis
- the upper part of the said bolt 5 similarly has, formed in it, a plurality of seats 14 also arranged in sequence in the manner of the teeth 13 arranged along the longitudinal extension of the bolt 5.
- Figure 6 shows in detail a preferred embodiment of the bolt 5.
- a movable element 15 having a plate-like form, referred to below as movable plate 15, is especially provided in order to keep the bolt 5 in the projecting position 10 and retracted position 9 which it assumes as a result of the action of the actuating means 8, or simply following rotation of the key through one or more turns in the direction in which this is permitted.
- the movable plate 15 is biased against the bolt by the action of resiliently yielding means 16 and is provided with engaging means 17 which are normally engaged in a retained relationship inside the abovementioned seats 14 of the bolt 8.
- the engaging means 17 may simply be formed by a tooth integral with the plate 15, as shown in
- the abovementioned resiliently yielding means 16 are advantageously formed by a flexible metal leaf which is secured at one of its ends to a special seat in the box- shaped body 2 and rests, under compression, with its other end against the upper part of the movable plate 15.
- the movable plate 15 is substantially formed by a thin - preferably metallic - element arranged so as to lie parallel to the support base 3 of the box-shaped body 2 and defined by two sides S, S' substantially parallel to each other and to said surface, a first one S of which being substantially flat and a second one S 1 of which having the engaging tooth 17 projecting perpendicularly with respect to its plane of lie .
- the movable element 15 may also assume other configurations which are different from the preferential plate-shaped form described above, but which nevertheless fall within the scope of the said inventive idea of this patent .
- the movable plate 15 is arranged on the outside of the bolt 5 with respect to the support base 3 of the box-shaped body 2.
- the movable plate 15 is also provided with a hole 18, preferably of the through-type, which is perpendicular to the two sides S, S' and is capable of receiving a pin 19 with an axis of rotation Z perpendicular to the support base 3.
- the pin is fixed to the box-shaped body 2 and mechanically connects the plate 15 to the said box-shaped body 2.
- the pin 19 forms, in accordance with the example illustrated in the accompanying figures, one piece with the box-shaped body 2 and is provided on a plinth 24 which projects upwards from the support base 3 in the vicinity of the front plate 4, as can be clearly seen in Figure 5.
- the pin 19 is instead integral with the movable plate 15 and extends perpendicularly from its second side S ' so as to engage in a corresponding hole formed in the box-shaped body 2.
- the plate 15 is substantially free to rotate on the box- shaped body 2, as indicated by the arrow F in Figure 3 and not to slide thereon. This rotation is however opposed by the compressive action exerted by the leaf 16, which tends to bias the movable plate 15 against the bolt 5, so that the engaging means 17 are constrained inside the seats 14.
- the movable plate 15 may perform rotary/translational movements or more generally have at least one rotary component and one component of displacement.
- the abovementioned hole may assume a cam-like configuration.
- the actuating means 8 by means of the projection 12, in addition to engaging with the teeth 13 so as to displace the bolt 5 in the direction of its axis X, at the same release the said bolt 5 from engagement with the movable plate 15 so as to allow displacement thereof.
- the projection 12 during its rotation produced by the key, interferes with the bottom profile 53 of the movable plate and, overcoming the opposing action of the leaf 16, is able to cause rotation of the movable plate 15 about the pin 19 and therefore raising of the engaging teeth 17 from the seats 14.
- the lock 1 comprises adjustment means 20 which are accessible from the outside of the box- shaped body 2 and act on the movable plate 15, imparting to it a rotation so as to engage/disengage the engaging element in/from the seats 14.
- the adjustment means 20 By operating the adjustment means 20, it is possible to overcome the resilient opposing action of the leaf 16 and cause rotation of the movable plate 15 by the amount needed to free the bolt 5 from engagement therewith.
- the latter once freed, is able to slide in the longitudinal direction of its axis X so as to allow it to be positioned with the projecting portion 5a extending from the front plate 4 by the desired length, which, as mentioned, will generally depend on specific applicational requirements.
- the adjustment means may in general impart to the movable plate 15 displacements having at least one rotary component .
- the adjustment means 20 may be preferably formed by an adjusting screw 21 inserted inside a threaded through- hole 22 formed on the front plate 4 of the box-shaped body 2 and intended to bear against a shaped portion 23 of the movable plate 15.
- the shaped portion 23 is formed by a lug extending perpendicularly from the second side S ' of the movable plate 15.
- a further advantage of the present invention relates to the particular arrangement assumed by the movable plate 15, on the outside of the bolt 5, which allows simplified assembly of the lock 1 and easier maintenance.
