Description

The invention relates to a handle, coat hook 0d. Like fitting for z. B. doors, windows, furniture, devices, machines with a dimensionally stable core and a cover therefor.

Handles for door locks, handles for doors and windows, twist handles, window olives, drawer handles and the like are known. B. to open or close doors, windows, drawers or flaps. Such fittings are often made of metal, for example cast zinc or aluminum, chrome steel or brass. Cloakroom hooks, grab handles or the like are known from the same materials. Construction fittings for windows, doors and furniture. Often such locking and construction fittings have common shape elements and / or color, so that they also "fit together" optically, for example when they are attached to different elements such as windows, doors, flaps and / or on different pieces of furniture or for this purpose are provided.
Such locking and construction fittings are also already known in designs which have a stable core, for example made of metal, and have a coating on the outside, for example made of thermosetting or thermoplastic.

These known locking or construction fittings still have a number of disadvantages. For example, its surface is unfriendly to the hand to be operated. This applies in particular to construction and locking fittings made of metal, the surface of which is hard and practically non-deformable by hand. Furthermore, this largely applies to such fittings with a thermoset or thermoplastic coating.
Another disadvantage of the metal fittings is that they are unfriendly due to their temperature behavior; they often become too warm when exposed to the sun for a long time and, if their surroundings are appropriately cold, become uncomfortably cold when they can be operated with the bare hand.

There is therefore the task of creating a handle, cloakroom hook or the like, which may be provided with a fastening base. Construction or locking fitting which, while largely avoiding the aforementioned disadvantages of known fittings of this type, is particularly easy to handle and use, and is good in different colors, shapes and sizes can be produced and does not pose an increased fire risk or create "disposal problems".

The solution to this problem according to the invention is in particular that with a handle, coat hook or fitting z. B. for doors or the like. Parts of the type mentioned in the cover of a semi-rigid polyurethane integral foam (short: PUR integral foam) of hardness from 35 to 95 Shore A.
Such a handle, cloakroom hook or the like. Construction or locking fitting has a particularly easy-to-grip surface and is somewhat resilient in cross-section. Furthermore, such a fitting is easy to manufacture and stable in different sizes and shapes it does not create "disposal problems". The latter means that a defective fitting according to the invention can be disposed of with household waste. In addition, such a handle, cloakroom hook or the like. Fitting still offers considerable advantages with regard to a fire risk: fittings according to the invention are not only normally flammable, such as, for. B. beech wood (DIN 4102); According to this standard, a handle or similar fitting according to the invention can be classified with the value B 2 and it also offers the following advantage: Because of the metal core, the handle, cloakroom hook or similar fitting according to the invention still remains in the event of a fire operable core, so that z. B. can also open a door or the like even when the cover has burned down. For this reason, the fittings according to the invention can even be used on fire doors if the fitting core is made of steel. Then the function of the door handle or the like is retained even when exposed to fire.

Experiments have shown that handles, cloakroom hooks or the like. Fittings which have a PUR integral foam layer with a density of 0.4 to 0.9 g / cm³ and preferably a hardness of 40 to 95 Shore A, are particularly user-friendly and easy to manufacture are.

In the handle or the like fitting according to the invention there is also the advantage that a special shape, e.g. Has recessed grips in a handle, can do without and still receives a comfortable handle; since the cover is correspondingly flexible, it adapts to the shape of the fingers of the gripping hand.

A particularly advantageous further development of the invention, for which independent protection is sought, consists of a handle, cloakroom hook or the like. The given if has a mounting base, the z. B. has a stop surface or the like. It is provided that at least one end of a pivoting or stop section facing away from a stop surface, a buffer-like, essentially formed by the cover 3 rubber-elastic projection is provided, which is preferably from a volume accumulation of PUR Integral foam is formed. Such a rubber-elastic projection acts on the one hand, for. B. for door handles, such as a door buffer, on the other hand, it represents a from the usual outline of such a handle od. Like. Outstanding, optical-aesthetic element, which makes related parts of a series of fittings appear to belong together.
For example, a door handle, a coat hook attached to the same door and a window olive can each be provided with such a projection in an analogous manner. This can then have both the technical function as a (door) buffer and / or the function as a common optical element. The same applies, for example, to drawer handles.

The provision of a buffer-like, rubber-elastic projection, which is formed from the semi-hard PUR integral foam, therefore offers an additional function as a buffer, can be used aesthetically for a special design and, despite these additional advantages, does not result in any significant additional effort Manufacture with itself.

A particularly advantageous embodiment of the handle according to the invention or the like. Fitting consists in that the outer outline shape of the rubber-elastic buffer is approximately half-lens-shaped or half-spherical. Such a shape favors both good manufacturability and the creation of smooth transitions on the outline shape. On the one hand, these soft transitions favor an optically cheap end see the handle or the like fitting and on the other hand an advantageous training of the skin.

In the case of a handle or similar fitting, this free end is expediently bent with at least one free end in the direction of the stop surface of the fastening base and provided with a coating there. Free ends of door handles bent in this way are known per se. The bend of its free end in the direction of the door surface has the advantage that people are less likely to accidentally hook their clothes in the door handle, which is usually L-shaped in profile, which can damage items of clothing, for example; In the worst case, minor injuries can also occur if, through this interlocking of the door and clothing of a person, somewhat more violent, surprising movements occur at the door and / or person. If the turn on known door handles, which are not flexible in their outline, but, which is not infrequently the case, reaches close to the door surface, crushing or injuries to the operating hand can occur when operating the door handle. With the handle or the like. Fitting according to the invention, which has a somewhat flexible covering, especially in the area of its free end, the risk of bruises or injuries is otherwise lower due to the flexibility of the covering.

1 to 3, a door handle designated as a whole is shown. It has a dimensionally stable core 2 made of metal (FIG. 3), which is shown in FIGS. 2 is indicated by dash-dotted lines. Around this core 2 there is a coating 3 made of a semi-rigid integral polyurethane foam with a density of 0.4 to 0.9 g / cm³ and a hardness of 40 to 95 Shore A. This coating is closed on the outside with a skin 4. This integral polyurethane foam is also referred to below as an integral polyurethane foam. To the door handle 1 includes an overall designated 5 mounting base. On this fastening base there is a cover part 6 for this fastening base 5. This also has a cover 3a on the outside, which corresponds to the cover 3 for the door handle 1. It also consists of an outside 4 integral PU foam on the side of a skin. The cover part 6 is fixed on the fastening base 5 by clipping. The fastening base 5 or its covering part 6 on the one hand and the door handle 1 on the other hand accordingly have the same appearance and a somewhat elastic, flexible outer contour with the same choice of color of the PUR integral foam.
The fastening base 5, which here is designed to match the door handle, for example, has a stop surface 7 with which the door handle 1 can be fastened in a known manner to the flat side of a door (not shown and not part of the invention). The door handle 1 continues from the fastening base 5 in a pivoting section 8 approximately perpendicular to the stop surface 7, in accordance with the section center line 20, which in turn comes to be practically perpendicular to the door surface. As usual, the door handle 1 is essentially L-shaped, the pivoting section 8 corresponding to the shorter L-leg and a handle designated 9 as a whole to the longer L-leg. A buffer-like, rubber-elastic projection 10 is provided on the end of the pivoting section 8 facing away from the stop surface 7. It is essentially formed by the coating 3. The dimensionally stable core 2 of the door handle 1 can have a core projection 11 corresponding to the rubber-elastic projection 10, so that the thickness d of the coating 3 in the area of this rubber-elastic projection 10 is essentially the same as in the remaining coating area of the core 2 (cf. 1 and 3). Equipping the door handle 1 with a cover 3 of substantially the same thickness can promote good manufacturability of the door handle 1 or its cover 3. As can be seen particularly well from FIG. 1, the outer contour shape 12 of the rubber-elastic projection 10 is approximately semi-lenticular to approximately semi-spherical. This can be a good producibility of the door handle 1 or its cover 3 and the formation of soft transitions the outer contour may be advantageous. Soft transitions on the one hand promote an optically cheap appearance and on the other hand advantageous, stable transitions on the skin 4.

If you form the outer contour of the core 2, however, in the area of the elastic projection 10 without a special core projection approximately according to the course of the dash-dotted line 2 ', the volume accumulation of rubber-elastic PUR integral foam increases and there is a correspondingly large amount of damping mass available.

From Fig. 1 it can be clearly seen that the free end 15 of the handle 9 of the door handle 1 is bent in the direction of the (extended) stop surface 7, which is indicated in Fig. 1 by the dash-dotted line 7a. At the free end 15 of the handle 9 according to FIG. 1, it can also be seen that the free end 16 of the core 2 is also bent somewhat in the direction of the plane of the stop surface 7 and is provided there with the door handle cover 3. Accordingly, the handle 9 of the door handle 1 is also made rubber-elastic in the region of its free, bent end 15. There he also has a completely closed cover 3 with a corresponding cover skin 4.- Particularly from FIGS. 2 and 3 it can be seen well that the handle 9 of the door handle 1 has a flattened support side 17 for laying on for an operating hand or the elbow . This essentially flat support side 17 is angled over a substantially continuous edge 18 (FIGS. 1-3) into the outwardly facing end face 19 of the door handle. This edge 18 can not only provide a favorable transition from the support side 17 (or a corresponding opposite side 17a) to the end face 19 of the door handle 1, but at the same time form an optical decorative edge 18 which can be found, for example, in the case of fittings parts belonging together as standard, such as door handles, drawer handles, etc. . repeated.

The point of view of the somewhat unified design can be shown particularly well when comparing the door handle 1 with the handle 101 described below according to FIGS. 4 to 6. This handle 101, which is approximately U-shaped in plan view (cf. FIG. 4), has a metal core 102, which is partly indicated by dashed lines and can be clearly seen in section in FIG. 6. It is tubular. The covering made of integral polyurethane foam is designated here by 103. This is also closed on the outside with a skin 4, as is known per se with such integral polyurethane foams. Depending on the construction, the handle 101 can be fastened directly, for example on a drawer face, as well as there with the aid of a fastening base similar to that in FIGS. 2 shown attached. 4 u. 6 proceed from the actual handle part 109, which is approximately U-shaped in the end profile (FIG. 5), connecting sections 108. They connect the handle part 109 to the part to which the handle 101 is to be attached. Their free, fastening-side ends have stop faces 7. The handle-side ends 120 of each connection section 108 facing away from these stop faces 7 are each provided with a buffer-like, rubber-elastic projection 10, essentially formed by the coating 103, as is used in connection with FIGS. 1 to 3 has already been explained in more detail. This elastic projection is formed both in the door handle according to FIGS. 1 to 3 and in the handle according to FIGS. 4 to 6 by a volume accumulation of PUR integral foam. Due to the clever design and volume accumulation, the cover 3 or 103 still takes on the function of an elastic buffer at desired locations. If necessary, an adapted core projection 11 can also be provided for each of the projections 10 of the handle 101 (cf. FIG. 6). As can be clearly seen from FIG. 4 and in particular FIG. 6, the outer contour shape 12 of the rubber-elastic projections 10 in the handle 101 is approximately semi-lenticular. The corresponding technical Advantages of this design have already been explained analogously in connection with the door handle 1 according to FIGS. 1-3. In the case of the handle 101, in analogy to the support side 17, a flat support side 117 is provided on the handle part 109 (cf. in particular FIG. 6). There, too, in the area of the handle part 109, this flat support side 117 intended for an actuating hand - seen in cross-section - merges into the end face 19 of the handle part 109 via an essentially continuous edge 18 (cf. FIGS. 4 and 6). Parallel to this edge 18, there is an analog edge 18a on the underside of the handle part 109, furthermore a corresponding edge 18b, which are provided on the bent legs 109a which lead to the connecting sections 108 and which also extend around the base of the projections 10 5 and - there, clearly visible in the front view according to FIG. 5 - run back into the edge 18 arranged on the handle part 109. This also corresponds to the course of the edge 18 in the door handle 1. This gives the same advantages with regard to the formation of this edge 18, 18a, 18b as have already been described in connection with the door handle 1 according to FIGS. 1 to 3. From a comparison of FIGS. 1 to 3 on the one hand and FIGS. 4 to 6 on the other hand, it is clear from the projections 10 and / or the edges 18, 18a, 18b that different fittings 1 or 101 are formed by the formation of the projections 10 and the edges 18 belong to a related, optically matched series.

The skin 4 or the like. Surface of the PUR integral foam can have a smooth or a matt surface design in a known manner, but can also have a grain or other engravings.

On the fastening base 5 or the like connecting part, the associated covering part 6 (see FIGS. 1 and 2) can not only be fastened by clipping, but it is also a form conclusive connection between the covering part 6 made of PUR integral foam, for. B. possible by direct foaming as with handle 9. However, a covering part 6 for a fastening base 5 can also be fastened thereon using an adhesion promoter.

The handle according to the invention, cloakroom hooks or the like. Fitting 1 or 101 can also be used well in the sanitary area, eg. B. in shower cubicles, bathrooms, baths, showers, etc. application. The same soft operating elements for fittings, handles and the like are also advantageous there, in particular for old people and / or the disabled.

As already mentioned, one can assign the rubber-elastic projection 10 to a corresponding core projection 11, as is shown in connection with FIG. 1 u. 2 is explained. A preferred embodiment is, however, if the rubber-elastic projection 10, as z. B. good from Fig. 1 u. 7 can be seen without a core projection 11 arranged on the inside, because then better damping and greater elasticity at this point of the door handle 1, 1a or the handle 101 etc. result because of the correspondingly larger volume accumulations of PUR integral foam; (See also the course of the core 2 ', as shown in dashed lines in Fig. 1.)

FIGS. 7 and 8 also show a rosette 60 arranged in the connection area of the fitting, which here forms a transition part between the pivoting section 8 and a door leaf 61.
The rosette 60 has a carrier part 62 with an outer covering of PUR integral foam applied thereon. This carrier part 62 is connected to a fastening part 63 attached to the door leaf 61.
The fastening part 63 consists of a screw-on plate, preferably made of sheet metal, the fastening holes 64 for through gripping screws. The fastening part 63 can thus be screwed onto the door leaf 62, on which in turn the outer rosette part can be attached.
As can be seen in FIG. 8, the fastening part has clamping webs 65 on its outer edge, by means of which the rosette carrier part 62 can be held in a frictional and / or positive manner. In particular, it is provided here that the rosette carrier part is pressed on from the outside and thereby latches with the fastening part at the clamping webs 65.
From Fig. 7 it can be clearly seen that the foam cover 66 is formed so that there is a continuous or harmonious transition between the subsequent pivoting section 8 on the one hand and the door leaf on the other.

All of the features described above and / or listed in the claims can be essential to the invention individually or in any combination with one another.
