    NEUTRAL POSITION, RADIOR FITTINGS AND METHOD
    The present invention relates to a neutral positional shield for a latch fitting or door fitting for the purpose of operating a door and / or a door lock in a door for bringing a door handle or a handle pin thereof to a neutral position. A further aspect of the present invention relates to a latch fitting using at least one shield according to the present invention. A further aspect of the present invention relates to a method for manufacturing a neutral position shield according to the present invention. A shield according to the present invention relates to a door shield in a range of sizes, including a so-called rosette. In general, round and square shapes are involved, but functionally this is not restrictive within the understanding of the invention.
    Solutions are known for bringing a door handle to a neutral position. Traditionally the spring action in the door lock has been used for this purpose. However, there are situations where the door lock cannot provide sufficient force to transfer the latch to the neutral position, such as with electromechanical locks. A perceived drawback is that when arranging a spring in the latch, this latch can only be used in situations where a design of a latch with a very thick appearance is acceptable.
    In order to improve the state of the art, the present invention provides a neutral position shield for a latch fitting or door fitting for operating a door and / or a door lock in a door for bringing a door handle or a handle pin thereof to a neutral position, shield comprising: - a cover element for covering a part of the door at the location of the operation of the door and / or the door lock, - a cavity in the cover element for arranging or arranged therein of a neutral position assembly for the reaching the neutral position, wherein the neutral position assembly is adapted to bring the door handle to the neutral position when it is in a position different from the neutral position.
    An advantage of such a shield according to the present invention is that it can return any door handle to the neutral position, since the functional parts for bringing it to the neutral position are incorporated in the cover element and therefore substantially no adjustments are required for a door handle per se. In addition, no adjustments are required for the lock arranged in the door.
    In a first preferred embodiment, the neutral position shield according to the present invention comprises positioning means for positioning urging means for urging the latch to the neutral position. Such a positioning means preferably comprise at least one engageable element, such as a surface, for bringing it to the neutral position under engagement thereof. An advantage hereof is that positioning to the neutral position can be achieved by a predetermined design of the positioning means.
    In a further preferred embodiment, the neutral position shield comprises urging means for urging the latch to the neutral position. The use of such urging means can advantageously provide energy for carrying out the movement to the neutral position. Preferably, such urging means function together with the positioning means.
    In a further preferred embodiment the neutral position shield comprises spring means for urging the door handle under spring force to the neutral position, wherein preferably the urging means as aforesaid are designed as the spring means.
    The neutral position assembly further preferably comprises a positioning cavity in the cavity, preferably for holding urging means. This makes it possible to arrange the neutral position assembly invisibly in use in a shield for a fitting. The spring means are herein preferably arranged in the postionation cavity.
    According to a further preferred embodiment, in the neutral position shield, the neutral position assembly comprises orientation guide means for guiding the crank pin to the neutral position, preferably under bias of spring means. By, for example, fixing the pin in the direction of rotation relative to the orientation guide means, it is possible to bring the orientation guide means and thereby the crank pin to the neutral position using the force of the support means. The orientation guide means herein preferably comprise a crank pin opening, preferably designed as a passage opening, for receiving the crank pin. Thereby, the orientation guide means preferably comprise at least one guide surface for guiding the orientation guide means to the neutral position, preferably under bias of spring means.
    In a further preference, viewed in the longitudinal direction of the crank pin, the orientation guide means comprise a square with rounded corners or a circle with flattened sides in view or in sectional view. Depending on the desired optical effect, the crank can hereby be positioned in any direction, such as horizontally. Hereby a gripping possibility is provided between the urging means and the crank pin or the orientation guide means.
    According to a further preferred embodiment, in the neutral position shield, the neutral position assembly comprises at least one leaf spring in the neutral position assembly, preferably two leaf springs arranged separately from one another, more preferably a number of leaf springs arranged pairwise for pairwise spring action. This creates a powerful spring action. This has the positive consequence that a neutral position assembly which is invisible from the outside can force the door handle to the neutral position.
    For an advantageous manufacture of the neutral position shield, the cavity and / or the orientation guide means are formed by means of a shaping operation such as cutting or milling or a shaping operation such as casting or injection molding. Alternatively, operations such as welding or clamping are provided.
    For a correct arrangement of the urging means, the cavity comprises extensions for arranging the urging means therein, preferably end parts of urging means. Hereby a correct arrangement with respect to the orientation guide means and / or the pin can be realized. Furthermore, it becomes possible to reliably maintain such an arrangement during use.
    Preferably, the cavity is formed in the cover element or in an insert member, such as an inlay, to be arranged in the cover element. An advantage of an insertion member, such as an inlay, is that different forms of the insertion member are possible when the cover element is formed. Alternatively, different forms of cover elements are provided with the same insertion member.
    According to a further preferred embodiment, the neutral position shield comprises a cover plate for covering the cavity on the door side. This makes it possible, for example, to supply an assembly with a neutral position shield sealed.
    Further advantages provided with a neutral position shield according to the present invention concern that the shields can be made narrow and wide, from for example a width of 30 mm, preferably a width from 35 mm, to for example a width of 100 mm, but there is no restriction to these values is prescribed and can be deviated from. Furthermore, use with so-called cranks is known to those skilled in the art as tubular cranks, which further increases the application possibilities for many different models. A further advantage is that a door handle can be rotated 360 °, so that a universally usable door handle set is realized, which makes separate versions turning left or right unnecessary.
    According to a further preferred embodiment, in a neutral position shield according to one or more of the preceding claims, the cavity is arranged on the door side of the neutral position shield. An advantage hereof is that the assembly is arranged invisibly in a simple manner by placing it against the door. Furthermore, the assembly is easily accessible by removing the shield from the door.
    Particularly when the neutral position shield comprises an ornamental shield, it is advantageous if the cavity is arranged on the door side, such as, for example, when the neutral shield and the ornamental shield are made of a part with a technical side in which the assembly is arranged and with decorative side.
    The neutral position shield further preferably comprises coupling means for attaching decorative shield. This makes it possible, for example, to arrange different decorative shields on a mounting shield. The mounting shield herein comprises the assembly, while the decorative shield can be arranged on the mounting shield.
    For a simple manufacture, the neutral position shield according to a further preferred embodiment comprises flanged flanges for forming the cavity. As a result, the shield, be it a mounting shield or the entire shield, can for instance be manufactured by means of a punching operation, preferably in combination with a conversion operation and / or a deep-drawing operation with a very limited number of treatment steps. The materials to be used can here be advantageously selected.
    A further aspect according to the present invention relates to a latch fitting comprising at least one neutral positional shield according to one or more of the preceding claims.
    A further aspect according to the present invention relates to a method for manufacturing a neutral position shield according to one or more of the preceding claims comprising steps for: - providing a cover plate with a cavity for arranging or arranged therein a neutral position assembly for reaching the neutral position, arranging a neutral position assembly in the cavity adapted to bring the door handle to the neutral position when it is in a position different from the neutral position.
