    Pressure neck guide and fitting assembly
    The present invention relates to a crank neck guide for door handles and or window handles and the like. Furthermore, the present invention relates to a fitting assembly for similar applications.
    For opening and closing doors, one or two door handles are used in addition to the internal mechanism for the physical closure of a door or window in a frame. The door is equipped with a cover plate, partly for decoration and partly to provide strength to the door handle. Hereby it is known that the door handle has frictional contact with the cover plate or the rosette or shield. Alternatively, it is known that a plastic ring is used to reduce this friction. However, these existing embodiments have the drawback that the friction generates wear, that there is play and that the protruding plastic ring does not provide a radiance of reliability.
    In order to obviate such drawbacks, the present invention provides a crank neck guide for guiding a crank neck into a deposit member, such as a rosette or shield for a door or window, comprising: - an inner guide member for contact with the crank neck, - an outer guide member for contact with the depositing member, wherein: - the inner guide member and the outer guide member are arranged coaxially with respect to each other, - at least one of the guide members is made of metal, and - the inner guide member and the outer guide member comprise positioning means for locating in a predetermined coaxial orientation with respect to each other.
    Using such a guide, the drawbacks of the prior art are overcome and a stable bearing is obtained with a minimum of friction, a maximum of durability and a solid appearance. The durability of the connection is greatly increased and unpleasant noises are prevented.
    In a first preferred embodiment, the crank neck guide comprises deforming means for allowing a deformation during an axial positioning operation for mounting the crank neck guide. These deforming means provide the option of mounting the guide according to this embodiment in a life-extending manner. Furthermore, using these deforming means, the effectiveness and the service life of the positioning means can be increased. If a guide member is made of metal, pre-mounting on the crank neck or the deposit member is possible.
    In a further preferred embodiment, the deforming means comprise slots in a guide member.
    Such a preferred embodiment can be manufactured in a relatively simple manner by manufacturing the slots in the body material of the inner sleeve or the outer sleeve.
    In a further preferred embodiment, the positioning means of the inner guide member and the outer guide member comprise engaging members movable in the bearing rotation direction and corresponding to each other, such as at least one slot and ridge, the positioning means of the inner guide member and the outer guide member. This embodiment of the positioning means is relatively easy to manufacture and provides a very robust positioning. Nevertheless, alternatives, for example the inclusion of one of the two bushes within protuberances at the ends of the other guide member, are equally possible. The envisaged embodiment provides a relatively compact structure of the crank neck guide according to the present insight of the inventors.
    The crank neck guide further preferably comprises a lubricating layer between the guide members. By means of such a lubricating layer, a long-term reduction of the frictional wear between the guide members can be realized.
    In a further preferred embodiment, the crank neck guide comprises an intermediate guide member for providing a further guide between the inner and the outer guide member. By means of such an intermediate guide, direct contact between the inner and outer guide members is prevented and therefore the friction between the inner and outer guide member is eliminated in the direct sense and greatly reduced indirectly. This intermediate guide member is an alternative in particular to the lubricant. The intermediate guide member preferably comprises a plastic. This includes relatively smooth plastics or relatively hard plastics. Examples are, for example, Teflon-containing plastics.
    The intermediate guide member preferably further comprises a metal. Such an intermediate guide member can be located between only the cylindrical walls or can have the same shape as the other guide members.
    In a further application example Crank neck guide the outer guide member is integrated in the deposit member. An advantage hereof can be a production method in which the outer guide member can for instance be manufactured by means of a casting operation with the depositing member, for instance metal or a plastic. Alternatively, the outer guide member can be placed in the depositing member by means of, for example, a pressing, welding or soldering operation, so that it is firmly anchored. An alternative to this is that the inner guide member is integrated in an analogous manner with or attached to a latch.
    In a further preferred embodiment, the friction surfaces of the intermediate guide members are provided with a surface machining such as small slots for improving bearing action and or directing molecules of a lubricant. Such a measure is advantageous in reducing the friction to which the guide members are subject.
    A further aspect of the present invention relates to a fitting assembly comprising a crank neck guide according to the present invention, comprising: - a deposit member, such as a door rosette or a door shield, - a crank neck comprising operating member, such as a door handle or window handle, wherein: - the operating member can be placed in an opening of the deposit member, and - the crank neck guide can be placed between the crank neck and the deposit member. Such a fitting assembly provides advantages as described above and as will be further specified below in the detailed description.
    In the fitting assembly, the inner guide member and the outer guide member are preferably rotatably arranged with respect to the crank neck and the deposition member, respectively. This prevents friction with regard to these parts, as a result of which all friction is absorbed by the parts intended for this purpose as described above. As a result, a problem-free operational function time is therefore considerably extended.
    Preferably, the crank neck guide is pre-attached to the crank neck or the deposit member. This measure has the advantage that during installation of the fitting assembly on a door or window, work is saved for the installation engineer. Also during the packaging and distribution of the batter assemblies, it is therefore not necessary to take the individual parts into account. As a result, a fitting assembly according to the present invention does not provide a further disadvantage with respect to fitting assemblies without a bearing according to the present invention which of course do not have such parts.
    In a further application elaboration according to the present invention, the crank neck guide extends into a body of a door or window. Relatively thin deposition members are possible here, which is advantageous in some applications.
    The fitting assembly furthermore preferably comprises a spring device for rotating the operating member to a neutral position. Such a spring device has the advantage that the desired, often horizontal, position is also assumed when relatively heavy door handles are used. The present embodiment has the advantage that fewer frictional forces have to be overcome, as a result of which the spring device has to apply less force for reliably effecting the correct orientation of the door handle.
    Further advantages, features and details of the present invention will be explained in greater detail below with reference to a few preferred embodiments with reference to the attached figures, in which: - FIG. 1 is a perspective view of two parts of a first preferred embodiment, loosely and assembled; FIG. 2 is a representation of the embodiment of FIG. 1 in an application example; FIG. 3 is a perspective view of a further preferred embodiment, loose and assembled; FIG. 4 is a cut-away perspective view of a preferred embodiment of FIG. 3 in the assembled state;
    A first preferred embodiment (Fig. 1) relates to a crank neck bearing 1 for use between a crank neck of a door handle or window handle and a cover shield or rosette that generally surrounds a door handle mounting pin, such as a pin (uk: spindle), of a door lock the outside of a door or window can be mounted. The bearing essentially comprises two bushes which can be arranged coaxially with respect to each other. The inner sleeve comprises a substantially cylindrical sleeve body which is provided with deformation slots 4 in the longitudinal direction. The deformation slots serve to allow deformation of the sleeve body 3 during its placement in the sleeve body 13 of the wider outer sleeve. Furthermore, the bush body 3 is provided with a substantially annular positioning rib interrupted by the deformation slots 4. This positioning rib 7 on the outside of the inner sleeve corresponds to the positioning slot 17 on the inside of the outer sleeve. As a result of the use of this ridge with slot cooperating with it, the two bushes will remain positioned in the coaxial direction relative to each other. The deformation slots 4 here have the function that the body 3 of the inner bush can be deformed during placing of the inner bush in the outer bush so that the rib 7 can reach the slot 3 while passing the rib 7 from the inside of the body 13 of the outside bus.
    A lubricant is preferably applied between the outside of the inner sleeve and the inside of the outer sleeve. Such a lubricant is preferably a type of grease with preferably as long as possible molecular chains to provide a lubricating action. During use, such long chains will arrange themselves substantially transversely to the longitudinal direction of the bushes, so that a long-lasting optimum lubrication with as little lubricant as possible can be achieved.
    During use of the bearing between the crank neck and the rosette, it is preferable that the inner bush fits tightly on the crank neck and that the outer bush fits tightly inside the rosette. In this case there is only movement between the two bushes, the corresponding surfaces of which are accurately adjusted to each other for a good mutual fit and an accurate bearing. These materials have been selected in an optimum manner for durability and bearing accuracy. This results in long-term bearing reliability. Furthermore, so-called squeaking noises are prevented. Such a bearing will also provide a very stable fit between the door handle and the rosette, thereby minimizing the sense of the usual play of the prior art. By a good coordination of the hardness of the material, a very long lifespan can be achieved, also in intensive areas of application such as public buildings.
    In FIG. 2, it is shown that the inner sleeve can be placed around the neck 21 of the crank. Furthermore, the outer bush placed in the door shield is shown.
    In the FIG. 4 a further preferred embodiment is shown. With respect to the first preferred embodiment, a further bearing element 31 is herein arranged which can be arranged between the inner bush 3 and outer bush 13. In this embodiment, these two bushes have a slot for receiving the ridges 33,34 on the inner surface and the outer surface of the body 32 of the bearing element 31. Alternatively, it is possible that one of the two ridges is replaced by a slot, or when the body 32 has sufficient volume two slots. In such a case, the surfaces of the sleeves 3,13 must be provided with corresponding ridges.
    Furthermore, it is possible that the positioning in said embodiments is achieved by means of shapes other than the slots and ridges. In the latter embodiment, the bearing element can, for example, be shaped such that the cross-section resembles a diamond with a relatively long vertical diagonal and a relatively short horizontal diagonal. Such an embodiment also provides a positioning effect. In the first embodiment, a kinked surface could also provide a positioning action.
    In this text the embodiment with a door plate is described wherein the door plate has such a thickness that it can receive the entire bearing. Alternatively, it is possible to use a relatively thin door plate in which the bearing is at least partially accommodated in the material of the door or the window.
    In the foregoing, the present invention has been described with reference to a few preferred embodiments. Different aspects of different embodiments are considered described in combination with each other, whereby all combinations that can be made by a person skilled in the art on the basis of this document must be read. These preferred embodiments are not limitative of the scope of this text. The rights requested are defined in the appended claims.
