Glass door fittings and manufacturing process

The invention relates to glass door fittings, namely to doors in which the entire sash, with the exception of associated fittings, is made of glass pane.

Such inventions in the field of construction and the latter in the field of door fittings and door locks belong either to door handles made of solid material, or to the area of fixing of the lock housing to the door leaf, or also to the field of construction of individual parts for attaching the sash, in particular fittings for wings with arms that are attached directly to the respective wing, which is rotatable about an axis beyond the plane of the wing.

The invention is based on the problem of the design of fittings for securely mounting and / or fixing and / or gripping and / or operating solely from the glass pane of a standing door leaf, such fittings should consist of as few components as possible and should be suitable for mounting directly it should be suitable for the economical and efficient execution of the surface treatment necessary to achieve a suitable and very important final appearance, while at the same time as the above requirements, the purpose of the invention is to design the most economical process for the manufacture of such fittings.

[0003] Some prior art are known in the art which allow the mounting of fittings to a glass pane door leaf. This is either a swivel or generally a sliding door leaf, which is made of relatively thick glass pane and at the point of attachment of the respective fittings, e.g. the handle or case of the lock or the like, provided with the required number of holes properly spaced. Such fittings consist of at least two fastening plates, each of which can be mounted on one side of the wing and each of which further comprises one cover plate. The fixing plates are intended for mounting and / or fixing the door leaf and, if necessary, for mounting parts or assemblies with which the wing is optionally fitted, e.g. hinges, locks or similar latch or other. The covers are intended solely to achieve a proper aesthetic appearance. One of the known solutions is described in DE 34 35 161 Al, where an additional relatively thin washer is provided on each side of the pile, which is adapted to fit on the surface of the glass pane and is also provided with holes through which the arrangement is aligned with those on the pile. Further, a thicker retaining plate is mounted on each side of the pile through said washer, which again comprises the arrangement of holes in the pile and the washers of holes appropriately spaced, a certain number of which are through holes and a certain number are threaded holes. Inserting the screws through the holes of the mounting plate on one side of the bar gives the possibility of screwing these screws into the mounting plate on the opposite side of the bar while screwing the threaded holes through the last mentioned plate into the threaded holes of the first mounting plate. Each of these mounting plates is either indivisible or screwed to a suitable hinge, but in principle may instead comprise a suitable recess to receive the lock. Each of these mounting plates is fitted with a cover or a cover. a rosette that e.g. consists of e.g. made of aluminum or brass or similar material, which, due to the proper surface treatment, gives the fittings a suitable aesthetic appearance.

This kind of hardware is functional and in its final and composite state, but also achieves the necessary aesthetic effects, on the other hand, it has a large number of components, which is associated with high production costs, high time consuming in installation and also with the possibility of complications in field installation. , which can happen e.g. due to mismatch of parts or simply due to incompleteness.

The manufacturing technology itself is related to the machining processes by cutting and to the transformation of the lids or the. rosettes which are subsequently treated by either grinding, polishing or other surface treatment processes.

The applicant is also aware of some attempts to make the fittings of two aluminum parts which would each be realized by the molding process. However, this technology does not work in practice for the simple reason that after casting it is not economically feasible, it is simply not possible to realize a surface treatment that would provide the necessary aesthetic appearance to the fittings thus produced.

The present invention relates to glass door fittings, namely fittings for securely securing and / or fixing and / or gripping and / or operating solely from the glass pane of a door leaf. Such fittings are adapted for attachment to a door leaf pile, provided for this purpose by means of appropriately designed and arranged holes and / or cutouts. The fitting according to the invention consists of two mutually complementary parts, which, by means of suitable connecting elements, are detachably interconnected in the region of said through holes in the pile, and optionally connected with each of the portions provided for connection with the door leaf at each time, or circuit.

Each of the complementary parts comprises the outer surface of the desired aesthetic appearance, except that said mutually complementary parts are interconnected by means of connecting elements selected from screws, in particular hexagon screws, hex head screws, cylindrical head screws , head screws, lens head screws, stand screws as well as catches and threaded pins. On the other hand, at least one of the complementary parts is individually connected and, in each case, the part or assembly intended to be connected to the door leaf is selected from the group consisting of hinges, lock assemblies, grips or. handles, guides, latches, safety latches, stop devices, stroke limiters, automatic opening and / or closing devices, moving devices, locking devices or sensors. Furthermore, the fittings according to the invention are characterized in that each of the two complementary parts of the fittings consists entirely of aluminum or aluminum alloy.

The subject of the invention is also a method of manufacturing fittings, namely a method of manufacturing each of the complementary parts of the fittings, the method comprising the steps of preparing a suitable semi-finished product or. a blank made of aluminum or aluminum alloy, compressing and thereby transforming said semi-finished product or. of the blank in a suitable tool, in solid state, thereby obtaining at least in the visible outer surface area at least in the form of a finely formed part of the hardware, optionally machining solely for the purpose of threading, stranding or similar areas for interconnecting parts or for their connection with other parts or assemblies located in the wing area, and optionally a fine and complete surface treatment when using the outwardly visible surface of each part of the hardware.

In doing so, the said compression step or. the transformation is carried out either at room or elevated temperature, and the step of fine and final surface treatment when using the exterior surface of each part involves sandblasting and / or polishing and / or plastifying and / or painting and / or coating an additional metal coating, in particular e.g. by means of galvanization.
