Description

SLIDING DOOR FOR DOOR PANEL CLOSING WITH HOOK

DOOR-LOCK AND HOOKING PLATE ON THE VERTICAL

RABBET DOORPOST AND ASSEMBLY SYSTEM OF THE

HOOKING PLATE

1] This invention relates to a sliding door for door panel closing, as in particular a glass door, with a hook door-lock located along the rabbet profile of the door and hooking plate located on the vertical rabbet doorpost, and an assembly method of the hooking plate.

Domain [0002] Slideable frames are known. In many building structures, of the industrial, commercial or housing type, sliding type doors are widely used. Especially in recent years, the use of such types of doors appears particularly in many architectural solutions especially in those where the containment with the habitability of internal spaces is a relevant element in the design of the building. Through the use of these doors, it is also possible to use more of those spaces that otherwise would have to be reserved in order to allow a conventional opening of doors hinged on hinges. Sliding doors of the vanishing type are structured in such a way as to comprise a series of fixed elements, intended to be integrated in the wall structure so as to constitute, being covered, a wall too, and a series of movable parts, the latter being intended to be used during the installation phase of the door, in order to be later removed at another time. In substance, for example, a counter-frame is integrated in the load-bearing structure. The abovementioned fixed elements are provided to be associated to the wall structure and include at least one large case for constituting the structure within which the door panel will be contained once it has been slid into the opening position, as well as a stanchion or better a doorpost provided to be fixed to the wall at the vertical profile of the doorframe, opposite to the side on which the above mentioned large case is positioned, in such a way as to allow the door itself, once placed in the closed position, to come into abutment with it. Furthermore, on the upper part of the large case itself a longitudinal guide is engaged, being screwed to said load-bearing structure. A sliding track is conventionally provided in order to allow the effective opening and closing movement of the sliding door. The door is hung on the abovementioned sliding track by means of conventional means, usually of the trolley type. Finally, to allow the opening and closing movement of the door, the sliding track, which is placed at the upper side of the structure of the doorframe, is usually provided with sliding means.

Prior art

3] In US2006071478 (Andre) a door-lock with at least one rotating hook is described, said rotating hook being movable along the vertical axis of the rabbet profile of the door, and able to be brought from a locking position to an unlocking position.

4] In JP2007023583 (Yutaka) a door-lock for a sliding door is described. It includes a movable hook which is rotating along the vertical axis of the rabbet profile of the door, and is operated by a key orthogonal to the hook itself.

5] JP2005163376 proposes a door-lock with movable hook for a sliding door, which is placed against one of the two faces of the door panel, and whose hook is offset with respect to the rabbet profile of the door panel, carries out a rotation from the bottom upwards, to engage the hooking plate fixed in a protruding way to the rabbet doorpost and sideways to the seat accepting the rabbet profile of the door panel. The hook hooking plate Consists of a hollow parallelepiped block, with a hook input slit and a tooth obtained by a lowering of the wall of the input slit itself.

6] In JP2002220955 (Takuo), JP2001317254 (Tsukasa) and JP10292693 (Hiroshi et al.) a door-lock with movable hook for sliding door is described, whose hooking plate is obtained enclosed in the rabbet doorpost of the door panel.

More relevant prior art

7] US4480862 (Fleming) describes a door-lock for a sliding door, provided with a hook movable along the vertical axis of the door panel.

The movement of the hook is substantially transverse with respect to the rabbet profile of the door panel and engages in a hooking plate secured by screws against the rabbet doorpost, where said hooking plate is composed by a base-plate with a horizontally projected wing from which a tooth is vertically protruding.

[00081 JP904 1759 (Miura) describes a closing device for a glass sliding door. The hook, by means of a cam lever, is placed against one of the two faces of the door panel, and is able to accomplish a rotational arched movement on the horizontal-plane for engaging a hook hooking plate fixed by means of screws to the rabbet doorpost beside the seat that houses the rabbet profile of the glass door. The hooking plate, in this case, consists of a base supporting an overhanging horizontal plate provided at an end of a hooking opening like a slit, inside of which the hook enters in the closing condition of the door.

[00091 JP9273344 (Matsuzawa), proposes a solution similar to the previous one. In this case the door-lock with the hook is integrated in the door panel, in such a way as to protrude with the hook beyond the rabbet profile. The hook cooperates with a manual movement lever, and accomplishes a rotational arched movement on the horizontal-plane, to engage a hooking plate that is placed inside the seat of the doorpost that houses the rabbet profile. The shape of the hooking plate is substantially "L "-shaped.

0] From what has been disclosed before it is therefore reasonable to consider known: O A sliding door that includes a counter-frame that houses a door panel, where said counter-frame essentially is composed by: a) a large case that constitutes the structure within which the door panel is contained once the door panel itself is slid to the open position, b) a rabbet doorpost intended to be fixed to the wall at the vertical profile of the doorframe, opposite to the one on which the above mentioned large case is positioned, in such a way as to allow the door panel, once placed in the closing position, to go in abutment on it with its door rabbet vertical profile, c) a sliding longitudinal guide or track with respect to which the door is hang by means of trolley means.

0 A door panel for a sliding door with a hook door-lock integrated along the rabbet vertical profile, where said hook which is hinged on a perpendicular axis, rotates along a vertical plane, and in which the hook hooks inside of a hollow seat with a retaining tooth embedded along the rabbet doorpost of the door panel; 0 A hook hooking plate joined outside of the rabbet doorpost with respect to the seat that houses the rabbet vertical profile of the door panel; 0 A hook hooking plate joined to the doorpost along the seat that houses the rabbet vertical profile of the door panel, for a door panel, that is provided with a door-lock with a hook, of the type with movable slide along a rectilinear axis and perpendicularly directed with respect to a face of the panel.

Drawbacks [0011] The above described solutions have, in the opinion of the applicant, some drawbacks. In particular, with reference to the solutions that integrate the door-lock with the hook that is located along the vertical rabbet profile of the door panel and that is hinged on a perpendicular axis, rotating along a vertical plane that coincides with the symmetry axis of the door panel, a particular work process is required of the carpenter during the assembly intended to obtain the corresponding recess, along the rabbet doorpost, intended for embedding the hooking plate which conventionally consists of a plate or box with input slit as already described for example in JP2002220955 (Takuo), JP2001317254 (Tsukasa) and JP10292693 (Hiroshi et al.). The performance of that work process, apart from requiring a particular precision in order to allow the correct operation of the door-lock, implies a lengthening of the installation time of the sliding door with evident higher costs.

2] All this considered, there is a reasonable need for the enterprises in the sector to find innovative solutions and to be able to overcome at least the above detected problems.

Summary of the invention

3] These and other aims are achieved by the present invention according to the included claims, solving the abovementioned problems by means of a closing sliding glass door with hook door-lock and hooking plate on the rabbet vertical doorpost and assembly system, in which the door panel for sliding door provided with counter-frame has an integrated hook door-lock along the rabbet vertical profile, where said hook which is hinged on a perpendicular axis rotates along a vertical plane, and in which the hook engages inside of the hooking plate consisting of a monolithic body with a base and a tooth protruding with respect to said base, the hooking plate being fixed along the vertical seat of the rabbet doorpost that is intended to house the vertical rabbet profile of the door panel. Aims

[00141 In this way, by the considerable creative contribution the effect of which constitutes an immediate and not negligible technical progress, different and important aims are achieved.

5] A first aim has been to obtain a sliding door which is characterised by the considerable installation easiness and speed, that make it significantly different from what exists already on the market. To perform the installation, in fact, no modification to the doorpost is required, which means that during the installation the intervention of skilled labour, e.g. the carpenter, is not necessary.

[00161 A second aim is to improve the aesthetic impact, as the hooking plate remains hidden in the seat of the rabbet doorpost that houses the vertical rabbet profile of the door panel, integrating in a harmonious way and with chromatic tonal coherence with the vertical gasket.

[00171 A third aim, has been reached in reducing the overall production costs of the sliding door.

8] In conclusion, these advantages, have the not negligible value to obtain a sliding door with a good technological content.

9] These and other advantages will appear from the following detailed description of some preferred embodiments with the aid of the enclosed schematic drawings whose embodiment details are not to be considered limitative but only illustrative.

Content of the drawings LI Figure 1 is a side view, according to the mounting diagram of the assembly of the sliding door; LI Figure 2 is a plan view of the assembly of the sliding door according to a mounting diagram; O Figure 3 is a frontal view of the hook hooking plate only; LI Figure 4, is a side view of the hook hooking plate of Figure 3 only; Li Figure 5, is a plan view of the hook hooking plate of Figure 3 and 4 only; Practical embodiment of the invention [0020] The present innovation, refers to a sliding door system 100 for the closing of the door panel 10, of the type with door-lock 20 with hook or latch 21 and hooking plate or latch plate 30 on rabbetted vertical doorpost 40.

[00211 More in detail, the sliding door system 100 includes at least one door panel 10, which is of the type made in materials as glass or plastic material for example polycarbonate or polymethyl methacrylate (PMMA), that could be of a neutral type, glazed, coloured, silkscreened printed or a combination of these characteristics. The door panel 10 is provided in a counter-frame that houses and allows the movement of the door panel 10.

In this case, said counter-frame, not shown, essentially consists of: a) a large case that constitutes the structure within which the door panel 10 is contained once the door panel 10 itself is slid from the closed position closing to the passage span, to the open position, b) a rabbetted doorpost intended to be fixed to the wall at the vertical profile of the doorframe, opposite to the side on which the mentioned large case is positioned, in such a way as to allow the door panel 10, once placed in the closing position, to come into abutment with it 40 with its door rabbet vertical profile or edge 11, c) a sliding longitudinal guide or track with respect to which the door panel 10 is hung by means of trolley means.

2] The door panel 10, (Fig. 1) along the frontal portion, integrates a door-lock 20 with knobs 23 whose rotation in either direction clockwise-counterclockwise, determines the movement, in one direction or the other, of the hooking hook 21 which activates the mechanism of the door-lock 20, exiting from its position inside of it, along the rabbet vertical profile 11 of the door panel 10 and protrudes, arranged to be hooked or latched to the hooking plate 30.

3] The hooking hook 21 presents a hook-beak like shape and is of the type hinged to a movement axis perpendicular to the side of the door panel 10 in such a way that the hooking hook 21 performs a movement along the vertical plane that in the specific case is passing through the symmetry axis of the door panel 10.

[00241 The hooking plate or latch plate 30 is fixed to the rabbet doorpost (Fig 2) in such a position as to coincide with the arched movement of the hooking hook or latch 21. More in detail the rabbet doorpost consists of a vertical lath with, in an intermediate position, a longitudinal hollow seat 41 with "U" shaped section containing the vertical gasket 50 and against or into which the rabbet vertical profile 11 of the door panel 10 engages. Inside the longitudinal hollow seat 41 the hooking plate 30 is fixed by means of screws 60.

5] The hooking plate 30 (Fig. 4) consists of a parallelepiped shaped monolithic block, in metallic or plastic material, with a main body substantially with rectangular plan that is provided with two through-holes 31 having a countersunk upper end, perpendicular with respect to the base 32 and to the top or front side 33. The edges 34 at the sides of the base or back side 32, are bevelled, easing the approaching of their base 32 to the bottom 410 of the longitudinal hollow seat 41. Regarding to the top side 33 of the hooking plate 30 one can observe that it is provided with a longitudinally projecting tooth 35 protruding orthogonally with respect to the first end 36 that is perpendicular with reference to the base 32. The head 350 of the tooth 35 is slightly bevelled in such a way as to provide a guide ramp for the hook 21 in the engagement phase to the hooking plate 30.

10026] The assembly method of the hooking plate 30 to the rabbet doorpost 40 requires the following steps: 1) moving the door panel 10 with the door-lock 20 installed, to approach the rabbet doorpost 40; 2) executing a mark or sign, eg with a pencil, on the rabbet doorpost 40, in the position that coincides with the hooking of the hook 21. For the models commercialized by the applicant, the sign in pencil is made at a level coinciding with the height of the lower end 22 of the door-lock 20; 3) moving away the door panel 10 from the doorpost; 4) positioning, at the sign in pencil, the hooking plate 30 inside of the seat 41 already existing along the rabbet doorpost 40 and against the bottom 410 of the seat. In the models commercialized by the applicant the positioning of the hooking plate 30 is made in such a way that the second end 37, its lower end, is placed in a position coinciding with the previously made sign.

7] In a first embodiment, the detected length between the first, top end 36 and the second, bottom end 37 of the hooking plate 30 coincides with the height a-a detected between the lower end 22 of the door-lock and the hooked end 210 of the hook 21 when the latter is in a hooking condition.
