Abstract
A sliding bolt (1) of the externally mounted type for a door (5) or window frame equipped with a safety lock (10) comprising a latch (3) which is manually operated by means of a lever (4) and slides inside a support (2). In the support (2) a front opening (7) is formed which is fit for the passage of a locking element (9) of the lock (10). The latch (3) is divided into two portions (3a,3b) connected to one another by arm means (14) sliding on the sides of a bushing (16) housed in the support (2) and defining a shaped cavity (8) in correspondence to said opening (7).
Description
- The present invention generally relates to the field of accessories for door and window frames and more precisely refers to a sliding bolt of the externally supported type to use in frames provided with a safety lock having more than one locking element.
- With the object of increasing security against intrusion, often in doors and similar frames safety locks are used which have multiple locking elements. Some of said locking elements engage in housings made in doorposts or lintels and, in the case of window or door frames with more than one wing, some locking elements engage in housings made in the wing adjacent to that holding the lock. One type of lock widely used for double doors has a central locking element and an upper and lower locking element which engage in the corresponding ends of the wing adjacent to that holding the lock. On the other hand the wing is fixed to the lintel or to the threshold by means of sliding bolts normally mounted in correspondence with those points in which it would be useful to make the housings of the locking elements of the safety lock.
- To avoid said interference, very short sliding bolts could alternatively be used and the housings of the locking elements could be formed at the end of said bolts.However, for a more effective functioning of the safety lock with triple locking element it is important that the upper and lower elements be as far as possible from the central element. Furthermore, it would be impossible to use longer sliding bolts of the externally supported type, which otherwise generally make more useful the operation of the lever for the opening/closing of the latch, in particular for the upper sliding bolt, which normally has a longer support in order to lower the lever to a height easily reached by a person.
- The object of the present invention is to provide a sliding bolt of the externally supported type for doors, windows and similar frames, which can be used in various sizes and which allows the use of safety locks having multiple locking elements some of which engage in the wing adjacent to the area in which the sliding bolts themselves are normally mounted.
- This object is achieved by the sliding bolt according to the present invention, comprising a latch which is operated manually by means of a lever and slides inside a support mounted on the window or door frame. Its novel feature consists in that a front opening is formed in the support fit for the passage of a locking element of the lock. In correspondence to the opening of the support the latch is divided into two portions connected to one another by arm means sliding on the sides of a bushing housed in the support and provided with a cavity in which the locking element of the lock engages.
- The invention will now be illustrated with the description which follows of one of its possible embodiments, given as an example, but not limitative, with reference to the attached drawings in which:
- Figure 1 is an elevational front view of a sliding bolt according to the present invention;
- Figure 2 is a partial view of a door to which two sliding bolts of different lengths according to the present invention are mounted;
- Figure 3 is a partial front view of a double-wing door including a partially sectioned detailed view of a locking element, of a safety lock applied to one wing, engaging with a sliding bolt according to the invention;
- Figures 4 and 5 are a front and a side longitudinal sectional view of a sliding bolt according to the present invention;
- Figures 6 and 7 are enlarged cross sectional view according to arrows VI-VI and VII-VII of figure 4 respectively.
- With reference to figure 1, a sliding bolt of the externally supported type generally indicated by 1 comprises an
elongated support 2 in which alatch 3 operated by alever 4 is slidingly engaged. - With reference to figure 2, the
sliding bolt 1 is mounted on adoor 5 by means ofscrews 6. In particular on thedoor 5 two slidingbolts 1 of different sizes are mounted, and the upper sliding bolt is longer in order to allow thelever 4 to be at a height which can be easily reached by anyone. - With reference to figures 1, 2 and 3, on the
support 2 of thesliding bolt 1 anopening 7 is made delimitating acavity 8 with alocking element 9 of asafety lock 10 can be engaged, as shown in figure 3. - With further reference to figure 3, a
sliding bolt 1 is mounted to onewing 5a ofdoor 5, thelatch 3 of which is shown engaging in ahousing 11 made in thethreshold 12. Thelocking element 9 oflock 10 is of the rotating type, the so-called "axe-type". For this reason, as shown in figure 1,cavity 8 has a substantially rectangular shape asymmetrical with respect to a transversal axis and in particular has a largerfirst portion 8a and a more narrowsecond portion 8b. - With reference to figures 1 and 3, the axe-
type locking element 9 during its rotation enters with a certain clearance in thefirst portion 8a and then, when the rotation is completed, is housed with precision in thesecond portion 8b. Clearly the shape just described ofcavity 8 is necessary only in the case of locks with rotating locking elements, whereas it is not necessary for locks with translating locking elements, wherecavity 8 can have a symmetrical rectangular shape. - With reference to figures 4 and 5, in order to form the
cavity 8 in whichlocking element 9 ofsafety lock 10 is housed,latch 3 is subdivided in two spacedportions arm 14 formed by twoparallel rods pins 15 are provided for to connect them to theportions latch 3. Insidesupport 2 of the sliding bolt abushing 16 is also fixed composed substantially of an elongated body in which there are formed thecavity 8 as well aslongitudinal guides portions latch 3 andpins 15. More precisely,guides cavity 8 since they help in the sliding theopposite portions respective pins 15.Guides 17 are, on the other hand, made on the sides of thecavity 8 in a transversal direction and positioned as close as possible to the edges of thesupport 2 so that they allow thecavity 8 to be wide enough to receive thelocking element 9. - With reference to figure 6, bushing 16 delimitates the
cavity 8 and fits in the opening 7 ofsupport 2. Furthermore, together with the support, it delimitatesguide 17 in which therod arm 14 are engaged. - With reference to figures 4 and 5,
holes 20 are formed on thebushing 16 through which thebushing 16 is fixed to thesupport 2 by means of screws 6 (visible in figure 1) which also have the function of fixing thesupport 2 of slidingbolt 1 to the door. In the case of locks with axe-type locking elements, thebushing 16, with exclusion of thecavity 8, is preferably symmetrical with respect to a transversal median axis. In this way, an upper sliding bolt can be transformed to a lower sliding bolt by simply rotating thebushing 16 with respect to support 2 thus keeping thenarrower portion 8b ofcavity 8 in a proper position (i.e. turned toward the floor) in both cases. - With reference to figure 3 according to the invention, it is possible to use a
sliding bolt 1 of any size and contemporaneously usesafety locks 10 placing them at the upper and lower ends of the door so that they have the maximum locking efficiency without interference with the sliding bolt used for securing the adjacent wing of the door.
