Description

The invention relates to a holder for releasably securing a flat, approximately rectangular device such as a tablet computer or a smartphone on a component, in particular on a component of a motor vehicle, wherein the holder has a holding device for releasably holding the device and a connected to the holder device Fastening element for connecting the holder to the component, wherein a rotatable about an axis of rotation pivot bearing is provided, which is connected to the holder means and wherein a pivot bearing connected to the pivot bearing are provided, which is connected to the fastening element.

Such holders are known from the prior art, for example from the EP 2 528 781 B1 known. In such, known from the prior art, the pivot bearing is connected to the pivot bearing indirectly via a second pivot bearing, whereby thus a kind of "Pleuellösung" can be realized by means of which the holder or the holder arranged on the device pivoted between two positions of use can be. It is conceivable to attach this holder by means of a trained fastener in a socket of a motor vehicle or to attach the holder, for example, indirectly by means of a dedicated attachment means to the headrest rods of a motor vehicle.

However, especially with large, new generation tablet computers that often have a size in plan view that exceeds the area of an A4 sheet, these holders have been found to be partially disadvantageous, particularly when mounted to the headrest bars. On the one hand, a position of the tablet computer in a portrait position due to the proximity to the vehicle roof or headliner due to the "connecting rod" can be prevented.

On the other hand, the novel, especially large tablet computers display sizes of 13 inches and more. This size of tablet computer also affects the mass of tablet computers, which also increases. In a crash case is the long lever arm of the EP 2 528 781 B1 known connecting rod disadvantageous due to the larger mass.

The invention is therefore based on the object to provide a holder for releasably securing a flat, approximately rectangular device such as a tablet computer or a smartphone to a component, in particular on a component of a motor vehicle, with the larger tablet computer stable and secure can be attached.

This object is achieved by a holder with the features of claim 1. Advantageous developments are mentioned in the subclaims.

For example, it is conceivable that the latching grooves have a latching groove profile, wherein the latching sections have a latching section profile which corresponds to a negative form of the latching slot profile.

It has proved to be particularly advantageous if the locking grooves and the locking portions have a profile which is designed such that a rotation of the first pivot bearing portion relative to the second pivot bearing portion to a displacement of the locking elements from the detent position to the release position against the spring force of the annular spring leads. According to an advantageous embodiment of the holder, the latching grooves are formed as V-grooves, wherein the latching elements having V-grooves corresponding V-shaped latching portions. A rotation of the first pivot bearing portion relative to the second pivot bearing portion thus leads to sliding of the V-grooves and the V-shaped latching portions toward each other in the circumferential direction. As a result of this sliding in the circumferential direction, the V-shaped latching sections are urged radially outward (i.e., perpendicular to the rotational axis of the pivot bearing) against the spring force of the annular spring and thus release the latching grooves again, so that the latching elements are moved from the latching position into the release position.

In a particularly inexpensive and at the same time stable embodiment of the holder a plurality, preferably 2 locking elements are provided, which are arranged in mirror image to the axis of rotation.

It has proved to be particularly advantageous if several, preferably 2, guide sections for the latching elements are provided on the second rotary bearing section, which are arranged in mirror image to the axis of rotation. Advantageously, the guide portions with the second pivot bearing portion rotatably connected or are in the second pivot bearing portion, for example. Cast by means of a plastic injection molding process, wherein the locking elements are guided in the guide sections. Due to the rotatably connected to the second pivot bearing portion guide portions guided in the guide portions latching elements can engage for locking with the first pivot bearing portion in the locking grooves such that the first pivot bearing portion is fixed relative to the second pivot bearing portion.

In order to be able to guide the latching elements particularly reliably, it has proved to be advantageous if the guide sections are designed to guide the latching elements. It is conceivable that an inner profile of the guide sections perpendicular to the axis of rotation corresponds to an outer profile of the locking elements.

Further details and advantageous developments of the invention will become apparent from the following description with reference to which an embodiment of the invention is described and explained in detail.
