Definitions
- the present invention relates to a lock, particularly for front posts for in-wall frames of retractable sliding doors.
- the frame embedded in the wall is usually constituted by a framework which comprises a plurality of vertical profiled elements, a front post and a rear post, which are connected by horizontal crossmembers which define a containment casing of the panel or of the door.

- Trolleys coupled to the upper edge of the door are slideably integrated in the rail in order to enable the sliding of the door into and out of the in-wall casing.
- an additional post that acts as a terminal for the abutment of the front edge of the door.
- Such conventional door frames thus use metallic profiles that can be mounted together and are sold for example in kit form for assembly.
- the doors are usually associated with a lock of the type constituted by a hook-shaped coupler, which can perform an oscillating movement that is such as to allow its temporary locking at a tooth that is present on the abutment frame for the door.

- the reference numeral 1 generally designates a lock for in-wall frames of retractable sliding doors which is constituted by a box-like structure 3 that is parallelepiped in shape, is open on one side and can be closed by means of a cover 32, and is connected frontally by a faceplate 4 which is provided with first holes 5a and 5b for coupling to the door.
- a cylinder 6 is arranged within the box-like structure 3 and is open at one end and closed at the other end by a wall 7 that is provided axially with a pivot 8 for pivoting to the backplate 9 of the box-like structure 3.
- Such pivot 8 is arranged in a substantially intermediate region between the first holes 5a, 5b and the cylinder 6 has a diameter that is such as to arrange its lateral surface 10 approximately tangential to the inner surface 11 of the faceplate 4.
- the cylinder 6 is thus idle and associated rotatably with the box-like structure 3, its lateral surface 10 skimming, during rotation, the inner surface 11 of the faceplate 4.
- the cylinder 6 rotates in contrast with a means that is arranged radially thereto and which makes it possible to achieve the temporary selection of a chosen position of the cylinder 6, the means being constituted by a receptacle 12 that is shaped like a parallelepiped, is associated with the backplate 9 and is arranged radially to the cylinder 6 in a region that lies above it, advantageously along an axis that is parallel to the inner surface 11 of the faceplate 4.
- the receptacle 12 has an open end 13 that is arranged adjacent to the underlying lateral surface 10 of the cylinder 6 and has a ball 14 arranged inside it which acts in contrast with an elastically deformable element 15, such as a cylindrical helical compression spring.

- a shank 28 of a knob 29 that protrudes externally to the box-like structure 3 is keyed to the hub 26.
- the selection of the position of the cylinder 6 is made possible by the presence of two third holes 30a, 30b that are provided on the lateral surface 10 of the cylinder 6, with which the ball 14 interacts selectively; the third holes 30a, 30b are provided in a position that is such that the ball 14 arranges itself thereat if the first portion 21 of the first seat 20 is arranged at the second hole 23 provided on the faceplate 4 and if the shaft 17 brings itself approximately at the closed end of the second portion 22.

Description
- The present invention relates to a lock, particularly for front posts for in-wall frames of retractable sliding doors.
- Nowadays it is known to provide door frames which involve the use of a casing, positioned inside a wall, in which a door or a panel is slideably associated and which is also known as a "retractable door".
- Such solution makes it possible to reduce the encumbrances of the door in a room thanks to the possibility of sliding it into the casing: thus one can use the space adjacent to the door, which would otherwise be occupied by doors of the type that are hinged laterally to a casement.
- In the known art, the frame embedded in the wall is usually constituted by a framework which comprises a plurality of vertical profiled elements, a front post and a rear post, which are connected by horizontal crossmembers which define a containment casing of the panel or of the door.
- Protruding above the case, along an axis that is longitudinal with respect to the case proper and that extends from the side opposite to that of the containment case, is a rail which is hidden by a jamb.
- Trolleys coupled to the upper edge of the door are slideably integrated in the rail in order to enable the sliding of the door into and out of the in-wall casing.
- Usually associated with the end of the rail which is not associated with the vertical post locators is an additional post that acts as a terminal for the abutment of the front edge of the door.
- Such conventional door frames thus use metallic profiles that can be mounted together and are sold for example in kit form for assembly.
- The doors are usually associated with a lock of the type constituted by a hook-shaped coupler, which can perform an oscillating movement that is such as to allow its temporary locking at a tooth that is present on the abutment frame for the door.
- Such solution suffers drawbacks, which consist mainly of the difficulty of achieving both optimal and rapid locking and unlocking between the coupler and the tooth, it being also possible for sticking to occur, which hinders such operations.
- Furthermore the locking is not particularly stable.
-
US 7 165 427 discloses a lock for a box, including a locking shaft, a lock shell, a lock core, a limiting unit, and a key. The lock shell defines a core-receiving space into which the locking shaft is removably extended, and the lock core is disposed movably in the core-receiving space. The limiting unit limits rotation of the lock core in the lock shell, and the key is operable to drive rotation of the lock core between locking and unlocking positions. - The aim of the present invention is therefore to resolve the above mentioned technical problems, by eliminating the drawbacks in the cited known art and thus devising a lock for in-wall frames of retractable sliding doors which makes it possible to obtain an optimal and stable closure of the door.
- Within the above aim, an object of the invention is to provide a lock that can be opened or closed rapidly and easily and with no sticking.
- Another object is to provide a lock that makes it possible to achieve an optimal and precise coupling with a locator element which is such as to ensure a stable open or closed condition.
- Another object is to provide a lock that is structurally simple, can be provided with conventional systems and machines, and is low cost.

Figure 17 is a side view of the interior of the box-like structure. - In the embodiments illustrated, individual characteristics shown in relation to specific examples may in reality be interchanged with other, different characteristics, existing in other embodiments.
- With reference to the figures, the
reference numeral 1 generally designates a lock for in-wall frames of retractable sliding doors which is constituted by a box-like structure 3 that is parallelepiped in shape, is open on one side and can be closed by means of acover 32, and is connected frontally by afaceplate 4 which is provided withfirst holes - A
cylinder 6 is arranged within the box-like structure 3 and is open at one end and closed at the other end by awall 7 that is provided axially with apivot 8 for pivoting to thebackplate 9 of the box-like structure 3. -
Such pivot 8 is arranged in a substantially intermediate region between thefirst holes cylinder 6 has a diameter that is such as to arrange itslateral surface 10 approximately tangential to theinner surface 11 of thefaceplate 4. - The
cylinder 6 is thus idle and associated rotatably with the box-like structure 3, itslateral surface 10 skimming, during rotation, theinner surface 11 of thefaceplate 4. - The
cylinder 6 rotates in contrast with a means that is arranged radially thereto and which makes it possible to achieve the temporary selection of a chosen position of thecylinder 6, the means being constituted by areceptacle 12 that is shaped like a parallelepiped, is associated with thebackplate 9 and is arranged radially to thecylinder 6 in a region that lies above it, advantageously along an axis that is parallel to theinner surface 11 of thefaceplate 4. - The
receptacle 12 has anopen end 13 that is arranged adjacent to the underlyinglateral surface 10 of thecylinder 6 and has aball 14 arranged inside it which acts in contrast with an elasticallydeformable element 15, such as a cylindrical helical compression spring. - First temporary engagement and retention means are provided on the
lateral surface 10 of thecylinder 6 for alocator 16 that is constituted by ashaft 17 that ends with aspherical head 18. - The
locator 16 protrudes from an abutment frame or rabbet 19 for the door 2. - The first engagement and retention means are constituted by a
first seat 20 that is T-shaped so as to define afirst portion 21, which is circular and has a larger diameter than that of thespherical head 18, followed by asecond portion 22 that is slightly wider than theshaft 17, thesecond portion 22 being extended over a chosen circular arc, considering a counterclockwise rotation as positive. - The
first portion 21 of thefirst seat 20 can be positioned at asecond hole 23 which is provided in thefaceplate 4 and is adapted to allow the passage of thespherical head 18. - Second means that can be activated by the user are provided on the
lateral surface 10 of thecylinder 6 in order to turn thecylinder 6, the second means being constituted by a plurality ofsecond seats 24 that are provided approximately opposite thefirst portion 21 of thefirst seat 20 and have a shape and mutual distance that are such as to allow their interaction withteeth 25 that protrude radially with respect to ahub 26 that is associated rotatably with asupport 27 that protrudes from, and is integral with, thebackplate 9 in a region that is adjacent to thecylinder 6 opposite thefaceplate 4. - A
shank 28 of aknob 29 that protrudes externally to the box-like structure 3 is keyed to thehub 26. - The selection of the position of the
cylinder 6 is made possible by the presence of twothird holes lateral surface 10 of thecylinder 6, with which theball 14 interacts selectively; thethird holes ball 14 arranges itself thereat if thefirst portion 21 of thefirst seat 20 is arranged at thesecond hole 23 provided on thefaceplate 4 and if theshaft 17 brings itself approximately at the closed end of thesecond portion 22. - In this way the
cylinder 6 is in a stable open or closed position, since it allows either the insertion in the lock of thehead 18 of thelocator 16, or the locking of thelocator 16 in thesecond portion 22. -
Figures 11 to 17 show third means that are adapted to temporarily occlude the inlet hole for thelocator 16 and to prevent the rotation of thecylinder 6 in the event the sliding door is open. - Such third means are associated at the inner
lateral surface 31 of acover 32, which is adapted to occlude the internal space of the box-like structure 3 and is associated rotatably with it by way of adaptedhooks seats inner surface 11 of thefaceplate 4. - The third means are constituted by a
cylindrical tumbler 35, which has a larger diameter than that of thesecond hole 23 defined on thefaceplate 4, and which can be positioned, in use, on the same axis of arrangement of thelocator 16. - The
tumbler 35 is in fact slideably and axially associated with aperforated tab 36 that protrudes perpendicularly to the innerlateral surface 31, ashank 37 protruding axially from thetumbler 35, on the opposite side with respect to thelocator 16, and being slideably associated with aflap 38 that protrudes perpendicularly from the innerlateral surface 31. - The axial sliding of the
shank 37 is limited by the presence of alocator 48 that protrudes radially from its end which in turn protrudes beyond theflap 38. - Coaxially to the
shank 37 there is an elasticallycompressible element 39, such as a cylindrical helical compression spring interposed between thetab 36 and theflap 38. - The dimensions and placement of the
tumbler 35 are such that it is, when the door is in the open position shown inFigure 14 , with thespring 39 pushing itsfront surface 40 to be positioned facing thelateral surface 10 of thecylinder 6 at thefirst portion 21, which has a larger diameter and so allows it to pass through and temporarily occlude thesecond hole 23 defined on thefaceplate 4. - In the region of the
cylinder 6 that, when the door is in the open condition, is above thefirst portion 21 and therefore thetumbler 35, there is aprotrusion 41 that prevents the anticlockwise rotation of thecylinder 6 which may be imposed by way of theknob 29 - In this way a level of security is obtained, since only if the
tumbler 35 is made to retreat sufficiently, and this occurs, as shown inFigures 15 and16 , only when thelocator 16 affects thesecond hole 23 and thus thefirst portion 21, will the clockwise rotation be permitted of thecylinder 6 thus achieving the closure of the door. - Only by rotating the
knob 29 clockwise will thecylinder 6 be made to perform an anticlockwise rotation until thehead 18 of thelocator 16 arranges itself at thefirst portion 21 and at thesecond hole 23 and, under pressure from thespring 39, the opening of the door is made easier. -
Figure 17 shows a fourth means that is adapted to define the positions of "open" and "closed", such fourth means being constituted by alamina 42 made of harmonic steel, arranged below thecylinder 6 and theknob 29. - The
lamina 42 is fixed at afirst end 43 to afirst wing 44, which protrudes from thebackplate 9, and rests on an adjacent, and underlying,second wing 45, which also rises from thebackplate 9 in a region that is closer to theinner surface 11 of thefaceplate 4. - The
second end 46 of thelamina 42 has a curved shape and is adapted to interact selectively with one of two complementarilyshaped undercuts cylinder 6. - The
undercuts second end 46 of thelamina 42 interacts with the undercut 47a the door is in the open condition, while when it interacts with the undercut 47b the door is in the closed condition. - Thus it has been found that the invention fully achieves the intended aim and objects, a lock being devised that makes it possible to achieve a simple closure and an equally simple opening of the door, it being necessary merely to pull the door to the locator and subsequently turn the knob.
- Furthermore an optimal and stable closure of the door is achieved thanks to the shape structure of the cylinder, it being possible to open or close such door rapidly and easily and without sticking.
- The lock further makes it possible to achieve an optimal and precise coupling with the locator element which is such as to ensure a stable open or closed condition.
- Furthermore the presence of the
tumbler 35 considerably improves the appearance of the lock, given that when the door is open, thespring 39 pushes it forward and it occludes thesecond hole 23 defined on thefaceplate 4. - The
tumbler 35 further increases security and the presence of the spring helps, when opening the door, the initial movement of the door proper. - Lastly, the lock is structurally simple and is low cost.
- The invention is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.
- The materials used as well as the dimensions of the individual components of the invention may be more pertinent according to specific requirements.
- The various means of achieving certain different functions certainly need not coexist only in the embodiment shown, but may be present in many embodiments, even if they are not shown. The characteristics indicated above as advantageous, convenient or the like, may also be missing or be substituted by equivalent characteristics.
- Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly, such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.

- The lock according to at least claims 5 and 6, characterized in that the selection of the position of said cylinder (6) is made possible by the presence of two third holes (30a, 30b) that are provided in said lateral surface (10) of said cylinder (6), with which said ball (14) interacts selectively, said third holes (30a, 30b) being provided in a position that is such that said ball (14) arranges itself thereat if said first portion (21) of said first seat (20) is arranged at said second hole (23) provided on said faceplate (4) and if said shaft (17) brings itself substantially at the closed end of said second portion (22).
- The lock according to one or more of the preceding claims, characterized in that said cylinder (6) can be arranged in a stable open or closed condition, since it allows either the insertion in said lock of said head (18) of said locator (16) or the locking of said locator (16) in said second portion (22).
- The lock according to at least claims 2, 3 and 6, characterized in that said third means are associated at the inner lateral surface (31) of said cover (32) that is rotatably associated with said box-like structure (3), said third means being constituted by a cylindrical tumbler (35), which has a larger diameter than that of said second hole (23) defined on said faceplate (4), and which can be positioned, in use, on the same axis of arrangement of the locator (16), said tumbler (35) being slideably and axially associated with a perforated tab (36) that protrudes perpendicularly to said inner lateral surface (31), a shank (37) protruding axially from said tumbler (35), on the opposite side with respect to said locator (16), and being slideably associated with a flap (38) that protrudes perpendicularly from said inner lateral surface (31).
- The lock according to claim 10, characterized in that the axial sliding of said shank (37) is limited by the presence of a locator (48) that protrudes radially from its end which in turn protrudes beyond said flap (38), coaxially to said shank (37) there being an elastically compressible element (39), such as a cylindrical helical compression spring interposed between said tab (36) and said flap (38), the dimensions and placement of said tumbler (35) being such that it is, when the door is in the open condition, with said spring (39) pushing its front surface (40) to be positioned facing said lateral surface (10) of said cylinder (6) at said first portion (21), which has a larger diameter and so allows it to pass through and temporarily occlude said second hole (23) defined on said faceplate (4), in the region of said cylinder (6) that, when the door is in the open condition, is above said first portion (21) and therefore said tumbler (35), there being a protrusion (41) that prevents the anticlockwise rotation of said cylinder (6) which may be imposed by way of said knob (29).
- The lock according to at least claim 7, characterized in that said fourth means that is adapted to define the positions of "open" and "closed" is constituted by a lamina (42) made of harmonic steel, which is arranged below said cylinder (6) and below said knob (29), said lamina (42) being fixed at a first end (43) to a first wing (44), which protrudes from said backplate (9), and resting on an adjacent, and underlying, second wing (45), which also rises from said backplate (9) in a region that is closer to the inner surface (11) of the faceplate (4).
- The lock according to claim 13, characterized in that the second end (46) of said lamina (42) has a curved shape and is adapted to interact selectively with one of two complementarily shaped undercuts (47a, 47b) that are defined on the perimetric edge of said cylinder (6), said undercuts (47a, 47b) being positioned so that when said second end (46) of said lamina (42) interacts with the undercut (47a) the door is in the open condition, while when it interacts with the undercut (47b) the door is in the closed condition.
