HANDLE SET

The invention relates to a handle set according to the preamble of the appended claim 1 and to a handle bearing that can be used therewith according to claim 13.

Door leaves are regularly fitted with such handle sets for the intended use. The handle sets used for this purpose are usually expensive due to their aesthetic design and long-lasting, good, well-maintained appearance. However, such handle sets are sensitive in that they are exposed to considerable risks of damage and soiling during the completion of a building in which the door is to be housed. However, the doors should already be accessible during this construction phase. In addition, depending on the wishes of the builder, a wide variety of door leaf types with different door leaf thicknesses and with door holes of different sizes prepared to accommodate the final handle set or the handle bearings that are regularly provided for these are used. The door holes provided in the different door leaves, which differ from one another in particular in size, are based on the

fittings to be used in each case. Despite the risk of damage and soiling, it has therefore made economic sense to make the doors accessible during the construction phase only with the specially suitable, i.e. the final high-quality handle fittings.

The invention is therefore based on the object of enabling the doors to be accessed during the construction phase in an economically viable manner without the risk of damage or soiling for the handle sets intended for use.

This object is achieved by a handle set with the features of claim 1 and a handle bearing that can be used with the features of claim 13.

The handle set according to the invention has - in addition to at least one door handle and a square pin that can be inserted into a recess provided therein - a handle bearing for adaptation to different door holes of different door leaf types, the outer diameter of which is graduated several times to engage in the door holes of different sizes. This means that one and the same handle bearing can engage in these door holes of different sizes with a correspondingly small amount of play. The handle bearing can therefore be used to adapt to different door holes provided in the door leaf in its handle area. The handle set can therefore be used as a makeshift handle set that only serves its purpose from the time the door leaf is installed until the building is completed. After the building is completed, the "noble" handle set intended for actual use, mentioned at the beginning, can then be used.

The use as a temporary handle set is economically viable due to the ability to adapt the handle set according to the invention to different door leaf types. After use, the handle set according to the invention can be removed and re-used elsewhere, even on a different door leaf type, without any risk of damage to doors or locks.

Advantageous embodiments, which in particular enable cost-effective production, easy installation and removal and improvements in terms of adaptability to different door leaf types, are the subject of the subclaims.

In a preferred embodiment, the handle bearing has several cylinder configurations of varying diameters to adapt to the door holes, which are designed one after the other in the axial direction, in such a way that the largest cylinder section, designed as a stop collar, is located in the axial middle area between the cylinder configurations, and that the cylinder configurations with decreasing diameters are connected to it on both sides, axially striving away from it. The largest cylinder section, designed as a stop collar, rests against the door leaf in a supporting manner when the largest of the cylinder configurations provided engages in the correspondingly large door hole. If the specified door hole of the door leaf is smaller, then the adjacent next larger cylinder configuration serves as a stop collar. With this handle bearing in a preferred embodiment, door holes of different stepped diameters can be controlled when inserted on the front side on the right or left. This handle bearing is preferably made in one piece from plastic.

In order to be able to take different door leaf thicknesses into account, the makeshift handle set is provided in a further preferred design with a loose square pin of a relatively long design, namely adapted to the largest door leaf thickness that occurs, which can be inserted into correspondingly deep square recesses in the door handles made of cheap, robust plastic, so that by engaging the square pin at both ends in the adjacent square recesses to different depths, the thickness of the door leaf area to be accommodated between the door handles can be correspondingly variable. To hold the square pin in the square recess of the handle in question, the pin is provided with an elongated recess running in the axial direction, into which a locking knob or the like can engage in the square recess. A large number of possible designs are conceivable for this pin/handle holder, which allow the holder to be brought about and released repeatedly.

All doors of the type in question can be equipped with such a temporary fitting for the construction period, which means that they can be opened and closed safely and without damaging the doors and locks. Although the invention is described below as a temporary handle set in accordance with its preferred purpose, it should be clear that the handle set according to the invention, in a correspondingly more elegant design, is also suitable for permanent use on a door leaf.

An embodiment of the makeshift handle set according to the invention is shown in the drawing, to which particular reference is made and whose following description explains the invention in more detail. They show:

Figure 1 shows a partially cut-out door leaf 2, in the door holes of which a makeshift handle assembly 1 is inserted. In the left-hand area, cut open, a handle bearing 3 is shown, into which the handle 4 engages and through which the square pin 11 (not shown) passes. In the right-hand handle area - door handle 5 - the handle bearing that appears on the outside is covered by a cap; the left-hand area could also symbolically indicate the representation of a permanent door handle.

Figure 1 shows the handle bearing 3 inserted into a door bore 15, whereby a corresponding

a suitably adapted cylinder section, for example 7, engages in this bore and the adjacent cylinder section rests on the outside of the door leaf 2 as a stop collar 6.

Figure 2 shows the side view, Figure 3 the top view and Figure 4 the diameter section of the pusher bearing 3. The pusher bearing 3 consists of the stop collar 6 of the largest diameter with four cylinder sections 7 and 8 on one side and 9 and 10 on the other side, which are formed on both sides with decreasing diameters and follow one another in both axial directions, which together form a plastic body. The top view shows the ring-shaped, closed hollow cylinder shape of the cylinder sections 6, 7, 8, 9 and 10. The sectional view shows the one-piece shape of the pusher bearing 3, which is formed as a support ring.

Figure 5 shows a square pin 11 and Figure 6 shows a pair of door handles 4 and 5, each of which is provided with a relatively deep square recess 13 into which the relatively long square pin 11 can engage at different insertion depths depending on the thickness of the door leaf. A locking knob is symbolically shown at 14, which engages in a long recess 12 in the square pin 11 in the axial direction, and in fact at different insertion depths of the pin in accordance with the long recess 12.
