Door-handle, window-handle, or sanitary elements

0001The invention relates to door and window handles and plumbing elements.

0002Known handles and sanitary elements are associated with the drawback that they regard to their visual appearance after manufacture and can no longer be changed, in particular during use. Thus, they must, if the user the visual appearance or the design no longer suits, complete with new grips or sanitary elements be replaced with modern design. This leads to adverse way to a considerable effort and cost.

0003An object of the invention is to provide elements of the aforementioned provide species whose optical appearance after Production and in particular changed during use can, without the entire element must be replaced. In particular, said change in the visual appearance also by a non-professional with minimum of time be comfortable bewerkstelligbar.

0004said object is achieved according to the invention by an element, wherein at least in the region of a portion of a base member with a is at least one-sided open sleeve detachably coupled, wherein the sleeve the primitive multilaterally surrounds the coupled state.

0005The present invention is directed to door and / or window handles of all kinds and on sanitary elements having a substantially rigid shape, such as Faucets handles, soap holders, handles, wall hooks etc. applicable. The Advantages of the invention and preferred embodiments are hereinafter by way of example with reference to a door handle or a door handle described.

0006By the inventive provision of the releasably connected to the base element coupled grip sleeve, it becomes possible, even during the latter replace use of the already mounted on a door leaf door handle, so that by exchanging the grip sleeve to the door handle with regard to its color design, its pattern and / or his Form a new look can be imparted. It is advantageous Manner allows all functional elements of the door handle including said base member to continue to use, so that in fact only the handle sleeve must be replaced, which compared to the replacement of the complete door handle a significant represents cost advantage.

0007By freedoms existing in the design of the sleeve, it is in particular also possible for the sleeve individually specific to a Users, for example, with the inclusion of pictures or corporate identity Smybolen, adapt. It can eg all door handles of a Company will be provided with a company logo.

0008to bewerkstelligendes A particularly simple and also by a non-specialist Replacing the grip sleeve is possible, when the releasable Coupling between base element and grip sleeve by means of a snap closure is realized. Such a snap-in lock can usually by a single simple operation - depending on the design of the latching fastener be solved, so that for an exchange - with or without tools the grip sleeve, only a minimum amount of time is required.

0009The snap closure can in particular through an opening formed in the grip sleeve formed recess and can be brought into engagement with it nose be, the latter being resiliently connected to the base member. In this case is likely to nose after completely pushing the Grip sleeve to the base member in said recess, and thus fixes the grip sleeve on the base element.

0010It is particularly easy to use the named snap closure, when the Recess is arranged in an end region of the grip sleeve, which the opening of the grip sleeve is remote. The recess is thus in provided an area which relatively far from that area the door handle has been removed, extending substantially at right extending angles to the handle portion and ultimately connect to the manufactures door lock. Thus, a good accessibility of the recess given for the release of the latching fastener.

0011Visually, it is advantageous when the recess on the side of The grip sleeve is arranged, which in the mounted state of the door handle facing the door panel, since one recess then frontal Top view of the door handle or door leaf does not see.

0012The recess may formed as a through bore be so coupled to the base element by means of a nose Tool from the outside of the grip sleeve forth in their unlocked is movable. The opening may be, to the inside outwardly tapered so that it inwardly a sufficient size for recording has the nose and from the outside - because of their low there Size - the external appearance of the grip sleeve as little as possible interfere.

0013A particularly good fixation of the grip sleeve on primitive results if the nose is resiliently connected to the base member having a Weird is provided that the grip sleeve in its locked position subjected to a force that the handle sleeve in its final coupling position fixed. Said force is substantially parallel directed towards the gripping sleeve in the direction of the portion which extends perpendicular to the handle portion.

0014Nose and primitive to each other via a movable arm be connected with the arm designed especially resilient and in the locking position is prestressed. In the relaxed state of the arm engages Thus, the nose of the base member into the recess of the grip sleeve. Contrary to the bias of the arm can nose out of the recess moved out and the grip sleeve are withdrawn from the base element.

0015A particularly secure connection between grip and primitive results when the arm particular additionally by means of a metal compression spring, preferably by means of a coil spring in the locking position is biased. In this case, not only acts the spring force of the arm out that the nose remains in the recess, but this position the nose is enhanced by said coil spring.

0016Manufacturing technology, it is advantageous when said metal compression spring in a bag-shaped recess, for example a bore the base member is fixed and substantially perpendicular extending to the longitudinal direction of the arm.

0017The basic element, for example, from plastic or with Plastic molded metal core. In this case, it is possible Nose, integrally build arm and base member and in particular establish by means of a single injection process.

0018As regards the cost of materials, it is useful when the replaceable Grip sleeve has a small wall thickness as possible, for example, can be between 1 mm and 4 mm.

0019If you want to achieve that through the exchange of a grip sleeve new shape is achieved, Tubes can also with varying Wall thicknesses are formed, wherein the different wall thicknesses in different sections of the grip sleeve then desired to Shaping result.

0020It is particularly advantageous when the grip sleeve with a plastic molded trim film is formed. Preferably, the decorative sheet is provided in the region of all the visible surfaces of the grip sleeve.

0021makes Providence a decorative film in the area of ​​all visible surfaces be achieved, in particular in that the decorative film of several, abutting and / or overlapping foil parts is formed, in particular by means of a single injection process with Plastic is injected behind. It is advantageous if the individual Film members prior to said injection operation under pressure and / or heat be preformed. These preformed foil parts can are then placed in a one or multi-part injection mold, wherein they largely flat against the preforming due to the injection mold. In the production of door and window handles, it is of advantage here when two preformed sheet halves are provided, each in a Half of a two-part injection mold to be inserted. The preformed Foil parts thereby form as it were two half-shells, which are then in a single injection process be back-injected with plastic.

0022Since all visible parts of the grip sleeve can be formed by the decorative sheet can, it is possible, as to behind spurting plastic example use of recycled or inexpensive material because this material is ultimately fully covered by the decorative sheet and thus does not is visible.

0023Since the decorative sheet in the case in the case of use of the invention Door handle by the user is to contacting surface, it is advantageous, if a particularly resistant, abrasion-resistant Film is used.

0024The invention relates in addition to the door handle above on a set of a door handle and more against each other exchangeable handle sleeves.

0025Further preferred embodiments of the invention are in the dependent claims indicated.

0026The invention is described below with reference to an embodiment Referring to the drawings; in which:<dl tsize="7"><dt>Fig. 1</dt><dd>a sectional side view of an inventive Door handle,</dd><dt>FIG. 2</dt><dd>a section AA according to FIG. 1,</dd><dt>Fig. 3</dt><dd>a section of the grip sleeve of FIG. 1 in the direction B,</dd><dt>Fig. 4</dt><dd>a sectional detail view of a door handle according to FIG. 1, wherein the grip sleeve is coupled to the base member, and</dd><dt>Fig. 5</dt><dd>a view according to FIG. 4 at the beginning of decoupling Grip and primitive.</dd></dl>

0027The illustration shown in FIG. 1 shows a substantially right-angled Steel core 1, which has a handle portion 2 associated Section 3 and a right angle to extending portion 4 has, wherein the portion 4 for receiving a - not shown - usual is four cornered suitable. At the end of the range 4 is a hub 5 provided that during installation of the door handle in the usual way in a circular recess of a locking plate is inserted.

0028Both areas 3, 4 of the steel core 1 is surrounded by a plastic sheath 6, wherein the plastic sheath 6 preferably by spraying on the Steel core 1 is applied.

0029assigned to the the region 4 facing the end of the handle portion 2 Area 3 is a stepped taper 7 is provided which Up to the remote area the 4 end of the handle portion 2 continues. The dimension of this stepped taper 7 or Height of the step formed by them corresponds to the wall thickness of Grip sleeve 8, which surrounds the handle portion 2 of the plastic sheath. 6

0030The grip sleeve 8 has in cross section a U-shape, ie, it is ultimately an unilaterally closed sleeve through the opening of the handle portion 2 assigned area of ​​the plastic sheath 6, which the one described in this invention the base element 9 forms, can be inserted into the handle. 8

0031Grip sleeve 8 and primitive 9 are designed so that the grip sleeve 8 in the coupled state shown in FIG. 1 in the region of its open End positively against the not surrounded by the grip sleeve 8 area 10 of the base member 9 is connected. This results in a flush Transition between primitive 9 and grip sleeve 8 so that when touched the door handle according to the invention by a user of two-piece construction of the handle portion 2 from the grip sleeve 8 and primitive 9 is barely noticeable.

0032On the field the 4 end portion remote from the base member 9 there is provided a substantially V-shaped incision 11 through which an in-this area of ​​the incision 11 area of ​​the base member 9 is formed as a resilient arm 12th are he-The spring action thereby the use of the elasticity of the base member 9 Plastic.

0033In the end region of the arm 12 is from the center of the handle portion 2 pioneering nose 13 is provided which to a complementary this Nose 13 formed recess 14 engages the grip sleeve. 8

0034In the arm 12 opposite the area of ​​the base element 9 a blind bore 15 is provided, which for receiving a compression coil spring 16 is extending up to the arm 12th This compression spring 16 supports the natural spring action of the arm 12 in such a manner that the nose 13 is held in the recess 14 of the grip sleeve. 8 To the Nose 13 from the recess 14 toward the center of the handle portion out move 2, thus has both the inherent resilience of the Arms 12 and the spring force of the compression spring 16 can be overcome.

0035The section AA of FIG. 2 shows again in detail between Primitive 9 and arm 12 arranged compression spring 16, wherein the overall arrangement from primitive 9, compression spring 16 and arm 12 of the Grip sleeve 8 is surrounded.

0036To the base body 9 in the center of the pressure spring 16 is a locking pin 17 is integrally formed, which projects into the interior of the compression spring 16, and this in addition fixed.

0037The shape of the grip sleeve 8 is shown in Fig. 2 are merely exemplary. Alternatively, any other cross-sectional shapes, such as round or polygonal or more ergonomically shaped cross sections are possible.

0038In particular, it is also possible, on one and the same base element 9 aufzustecken differently shaped grip sleeves 8, so that the door handle ultimately different shapes can be imparted without body 9 having to change with steel core. 1

0039Fig. 3 shows a section through the grip sleeve 8 in the direction of arrow B of FIG. 1.

0040Here again the substantially U-shaped cross-section of the grip sleeve 8 recognizable. In particular, the arrangement of the recess 14 shown at that end of the grip sleeve 8, which the opening 18 the grip sleeve opposite.

0041FIG. 4 again shows a detailed view of Fig. 1, whereby in particular It can be seen that the nose 13 is provided with a bevel 19, which is arranged on that side of the nose 13 of the opening 18 (Fig. 3) facing the grip sleeve 8.

0042This bevel 19 in conjunction with the spring action of the arm 12 and of the compression spring 16 causes the grip sleeve 8 in the direction of arrow C. is pulled as shown in FIG. 4 so that the front end of the opening 18 the grip sleeve 8 formed ultimately fully on the at 7 (Fig. 1) Level of the base member 9 is applied and thus a flush transition between Grip sleeve 8 and ensures the area 10 of the base member 9 is.

0043When loosening the grip sleeve 8 from the base element 9 is shown in FIG. 5 a Tool 20 from the outside in the direction of arrow D in the as continuous Opening recess formed 14 introduced, whereby the Nose 13 against the spring action of the arm 12 and the compression spring 16 is pushed toward the center of the handle portion. 2 To this Manner, the nose 13 disengaged from the recess 14, so that the grip sleeve 8 ultimately in the direction of arrow E from the base element 9 can be removed.

0044It is then possible, instead of the grip sleeve 8, any other Tubes plugged onto the base body 9, in order in this way to change the appearance of the door handle according to the invention.
