Description

Door handle

The invention relates to a door handle, in particular for sliding doors, with a receiving part assigned to the door and at least one handle part.

Generic door handles are preferably used for sliding doors, with a design that is as flat as possible so that they do not take up too much space. In high-quality door systems, these are moved almost completely automatically from the closed to the open position and back via a drive motor, so that door handles are generally not required. In the event of a power failure or malfunction, however, it must be ensured that the doors can also be opened by hand. It is therefore necessary to provide appropriate door handles that allow the doors to be pushed open manually. Known versions of generic door handles are, for example, glued, screwed or otherwise attached to the door frame, with the door handle preferably only being formed on one side of the door. If, on the other hand, high-quality materials, such as glass or plexiglass doors, are used, the door handles cannot be used according to the known state of the art.

The invention is therefore based on the object of creating a door handle which can be used independently of the door material used and which, due to its structural design, requires only a small amount of space.

According to the invention, the object is achieved by providing that the receiving part consists of a sleeve that can be inserted into a hole in the door and that the handle part is designed in a trough-shaped manner and can be placed on the sleeve. The solution shown only requires a hole in the door leaf or the glass door to attach the door handle, whereby the

Handle parts of the door handle come into contact with the surface and clamp the door leaf. The door handle is preferably constructed in three parts and consists of the sleeve, which is inserted into the hole, and two corresponding handle parts, which are connected to the receiving part. This can be done, for example, by clamping or by corresponding fastening means. Alternatively, it is possible for the sleeve to be equipped with an external thread onto which the handle parts equipped with an internal thread are screwed.

The use of a screw-on handle part on both sides makes it possible to use identical door handles for different door leaf thicknesses, as the inserted sleeve allows the handle parts to be screwed on until they rest against the door leaf. The door leaf can be made of wood, a plastic material or, in particular, an all-glass door, whereby the sleeve and the screwed-on handle parts prevent any risk of injury on the edges of the hole due to the completely overlapping arrangement.

In a preferred embodiment, the sleeve has a wall lying in the axis of symmetry or two radial walls arranged offset to the axis of symmetry in order to obtain a completely closed door surface and, moreover, to prevent objects from being pushed through the existing hole in the door leaf.

This is preferably achieved by having a plate-shaped insert pressed into the sleeve on both sides, which surrounds the sleeve with its front edge and thus forms an attractive and non-slip transition that prevents any kind of injury. The handle parts are screwed onto the sleeve until they are in contact with the door with one flat side, whereby if necessary.

A rubberized intermediate layer is placed between the plan side and, in the case of the use of all-glass doors, in order to avoid damage to the glass door.

In a special embodiment of the invention, the handle parts have an inward-facing flange collar on the through hole, which has an undercut, the flange collar preferably being assigned to the radial surface spaced from the door. The flange collar serves on the one hand to form a stop for the sleeve and on the other hand the existing undercut forms an annular groove for receiving the sleeve. The depth of the undercut is selected so that the door handle can be used for different thicknesses of the door leaf or an all-glass door. If smaller door thicknesses are used, the handle part can be screwed onto the sleeve as far as it will go and the front edge of the threaded sleeve dips into the undercut. In the case of larger door leaf thicknesses, it is only possible to screw it partially onto the sleeve, whereby the protruding inner edge of the undercut still ensures an elegant transition to the sleeve and thus all door thicknesses within a certain limit range can be equipped with a single door handle. Usually, door leaf thicknesses for wooden or glass doors are 8-15 mm thick, so that the door handles according to the invention can cover this variation in door leaf thickness due to the overlap formed.

To allow for individual adjustment of the door handles, they are rounded, bevelled or chamfered on the side facing away from the door, for example. The bevel can be designed at different angles to the axis of symmetry, creating extremely flat handle parts or recessed grips that do not affect the overall impression of the door system and can be used inconspicuously but expediently.

The invention is explained in more detail below with reference to the following figures.

Design of the door handle after assembly.

Figure 1 shows the individual parts of a door handle 1 according to the invention in a top view and in a sectional side view. The door handle 1 consists of a sleeve 2 and two identical handle parts 3. In the top view, only the handle part 3 with its external shape is visible, while in the sectional side view the other details are better visible.

The sleeve 2 is mirror-symmetrical and has an external thread 4 onto which the handle parts 3 are screwed for assembly. To avoid jamming, the external thread 4 is only formed in the middle area and has a cutout 5 on the outer edges. The sleeve 2 is double-T-shaped in its cross-section, so that there is a middle wall or intermediate wall 6 that prevents anyone from reaching through the sleeve 2. For a better visual design, the resulting recesses 7, 8 can either have a colored design or have a pressed-in plastic sleeve.

The handle parts 3 can be used on both sides and have a bore 9 which has an internal thread 10 on the side facing the door. On the opposite flat side or radial surface 14, an inwardly directed flange collar 11 is integrally formed which has an almost rectangular undercut 12 so that when the handle parts 3 are screwed onto the sleeve 2, the front edges of the sleeve 2 can engage in the undercut 12. In the embodiment shown in Figure 1, the radial surface 14 of the handle parts 3 facing away from the flat side 13 is provided with a bevel 15 which merges into the axial surface 17 via a rounding 16, so that an outwardly protruding flat transition is created which has no sharp edges and thus eliminates the risk of injury. Alternative embodiments of the handle parts 3 are shown in Figures 4 and 5.

Figure 2 shows a door handle 1 according to Figure 1 after assembly without a door leaf, with the two handle parts 3 screwed onto the inner sleeve 2. From this cut side view, it is very clearly visible how the outer edge of the sleeve 2 engages in the undercut 12 of the handle parts 3, so that a clean transition is created on the inner surface, namely where the fingertips engage in the door handle, and the risk of pinching, injuries or the like is prevented.

Figure 3 shows the door handle according to Figure 2 after installation on a door leaf or an all-glass door 18, wherein the radial surface 14 has a slight bevel 15 towards the axial surface 17 and the transition is additionally equipped with a rounding 16 in order to achieve the already mentioned advantages of an attractive finish.

Figure 4 shows a door handle 20 according to the invention after assembly on a door leaf or an all-glass pane 18. Compared to the known design, the only difference is that the front visible radial surface 22 is flat and only has a rounding 23 for

axial surface 24. The two handle parts 21 are screwed with their internal thread onto the external thread of the sleeve 2 and also have an undercut 25.

Figure 5 also shows, in a sectional side view, another embodiment of a door handle 20, which is equipped with two handle parts 21, which are screwed onto an identical sleeve 2 on the one hand and have a 45° bevel 32 from the radial surface 33 to the axial surface 34 on the other hand, with the transitions additionally being rounded. The sleeve 4 comes to rest in an undercut 35.
