Description

The invention relates to a holding device for holding an object on a base, for example for holding a bicycle on a vehicle mountable bicycle holder. The holding device has a base structure which can be fastened to the base, with a receptacle for at least part of the object, a flexible traction device, which surrounds the object for connection to the basic structure on a side facing away from the receptacle and presses against the receptacle, a connecting device of Basic structure, which preferably connects the flexible traction means at a first connection point with the basic structure releasably and a tensioning lever, which is connected to the traction means at a different from the first connection point second connection point. The tensioning lever is connected to the basic structure in a swivel joint and can be moved back and forth between a closed position in which the flexible traction means clamps the object against the receptacle and an opened position.

It is an object of the invention to provide a holding device available that can be preset and easily operated with one hand.

This object is achieved by a holding device according to claim 1.

The holding device according to the invention for holding an object on a base comprises a basic structure, which can be fastened to a base, with a receptacle for at least a part of the object.

The article may be, for example, a bicycle or bicycle frame, a cannula, a cannula holder or other healthcare items, or other object, such as a gas cylinder or vessel, releasably connected to a base via a retaining device shall be. The shape or the peripheral shape of the object to be held is basically arbitrary. The basis for the bicycle may be a bicycle holder, for the needle holder a hospital bed, for another object, for example, a housing wall.

The holding device further comprises a flexible traction means, which engages around the object for connection to the basic structure on a side facing away from the receptacle and presses against the receptacle.

As a pulling means here is any means, such as a band, a chain, a belt and the like to understand, with a tensile force is transferable. It is not excluded that the traction means can also transmit compressive forces, such as a metal band. Preferably, however, the traction means can transmit higher tensile forces than compressive forces. The fact that the flexible traction device engages around the article implies that the traction belt for connecting to the basic structure passes through part of the object, that is, for example, through a slot or cavity formed on or in the article. That is, the traction means need not encompass the entire outer circumference of the article in the region of the attachment for attaching the article to the basic structure.

The holding device further comprises a connecting device of the basic structure which connects the flexible traction means to the basic structure at a first connection point and a tensioning lever which is connected to the flexible traction means at a second connection point different from the first connection point. The tensioning lever is connected to the basic structure in a rotary joint, preferably connected directly to the basic structure in the rotary joint. This means that in this case a part of the joint forms the basic structure or a first joint element fixedly connected to the basic structure, the second part of the joint or the second joint element is formed by the tensioning lever or a part of the tensioning lever.

Preferably, the clamping lever is connected to the traction means at one end of the traction means or connectable. The length of the traction means can be set defined by means of the connecting means, that is, the connecting means can grab and fix the traction means at any point. When the tensioning lever is then opened or closed with traction means held in the connecting device, a clamping length of the traction means, that is to say the length of the traction means measured between the connecting device and the tensioning lever, remains unchanged (memory effect). As a result, the same object can be connected several times in succession to the basic structure, without the length of the traction device having to be readjusted. For example, the user can hold the bicycle in the holding device with one hand and tilt the clamping lever with the other hand.

The length of the pulling means may be adjusted prior to securing the article. If a plurality of different sized objects, for example cannula holder or medicine bottles, can be held one after the other with one and the same holding device, it can be useful to provide the traction means with marks in order to be able to reliably set the length of the traction means to the new object before use.

By way of example, the connection device may be a clip which is preferably connected to the basic structure in a rotary joint and is preferably tiltable between a clamping position in which it clamps the flexible traction means and a release position. The connecting device can clamp the traction means in the clamping position by a flat, linear or punctiform pressing of a clamping end of the connecting device against the basic structure.

In this case, the clip or the connecting device can be biased in the clamping position against the basic structure. This clamping effect can be generated by an elastic element, for example a compression spring, which can be designed, for example, as a spiral spring or leaf spring. The connecting device must then be pressed against this spring force in the release position, in which the traction means can be inserted into the connecting device and the effective length of the traction means can be adjusted. In the clamping position of the connecting device, the traction means can no longer be moved relative to the clamping end of the connecting device.

The tensioning lever may comprise at least two parts which are connected together in a hinge. In this case, a first part of the clamping lever can be connected in the rotary joint with the basic structure and a second part of the clamping lever can be connected to the traction means. The pivot connecting the first part to the base structure is preferably formed so that the tension lever in the open position can be detached by disconnecting the hinge from the base structure and restoring the hinge connection to make the connection of the object to the base structure. For this purpose, a recess formed on the tensioning lever, for example a groove, can serve as a joint bearing for the joint and a joint element formed on the basic structure can be designed as a joint or rotation axis. For connection, the tensioning lever with its joint element, the groove, is then suspended in the joint element, the axis of rotation, of the basic structure, whereby the rotary joint, which connects the tensioning lever to the basic structure, is formed. Alternatively, the joint element may be formed on the tensioning lever as a rotation axis and the joint element on the basic structure form the joint bearing in the form of a groove or recess.

Before the locking of the clamping lever in the closed position, there may be an over-snap of the clamping lever parts, whereby a force for closing the clamping lever is required, which may be greater than the clamping force of the traction means in the closed position of the clamping lever.

The clamping lever is preferably in the closed position on the basic structure at an angle which causes an intrinsic safety of the clamping lever. For additional securing of the clamping lever on the basic structure in the closed position, the clamping lever on its basic structure side facing securing elements, such as knobs, grooves, projections or Hintergreifungen have that interact with corresponding counter-elements on the basic structure and the clamping lever in the closed position against unintentional Secure release.

The traction means may be a belt, a belt, a rope, a chain or another suitable flexible object, it is preferably a traction means made of plastic, particularly preferably a toothed belt made of plastic. The teeth of the toothed belt in the functional state of the holding device preferably have away from the basic structure, that is, are formed on the side of the toothed belt, which does not abut against the basic structure.

As a result, the connecting device or its clamping end can engage between two teeth of the toothed belt in order to securely fix the toothed belt to the basic structure by means of the connecting device. It goes without saying that the clamping end can also have a shape that simultaneously engages in two or more interdental spaces of the toothed belt. The interdental spaces may be triangular, square, the teeth themselves may also have hook shape. The clamping end of the connecting device corresponds approximately to the shape of the interdental spaces or is formed as a counter hook to the hook shape of the teeth.

For reinforcement, the traction means may comprise a reinforcing element, for example a steel strip or a metal chain, the reinforcing element may preferably be injected into the traction means. The reinforcing element not only increases the tensile strength of the traction device, but also complicates a severing of the traction means by means of, for example, a knife. The reinforcing element therefore also makes it difficult to steal the article.

A further anti-theft device can be achieved in that the basic structure has a locking device with which the connecting device and / or the clamping lever can be locked in the closed position. Such a locking device may comprise an actuating element and a locking element for the clamping lever and / or a blocking element for the connecting device. By a rotation of the actuating element, the blocking element of the connecting device and / or the blocking element of the actuating lever can be moved into or out of the blocking position.

If the locking device has a blocking element for the connecting device and a blocking element for the tensioning lever, then both blocking elements can be identical in construction and can be moved synchronously during a rotation of the actuating element. For example, the actuator may include a gear or an array of gears that cooperate with a rack member on each of the two blocking members. In the blocking position, the blocking element for the locking device can prevent it from being moved into the release position, that is to say the locking device is blocked in the clamping position. The clamping lever can be blocked by the blocking element for the clamping lever in the closed position, for example by engaging in or behind a molded on the clamping lever holding structure, such as a groove.

However, the locking device can also be designed so that the blocking element for the clamping lever and the blocking element for the connecting device are moved independently of each other, for example, successively by the adjusting element. Thus, when turning the control element in a first position initially only the clamping lever can be released from its blocking position, while the connecting device is still blocked. Thereby, the holding device can be opened and the object entered into the holding device or removed from the holding device, while an unintentional adjustment of the length of the traction means is excluded by the continuing blocking of the connecting device. By further rotation of the actuating element in a second position and the blocking of the connecting device can then be opened deliberately. When assembling the basic structure with the traction means, conversely, first the traction means or the connecting device can be blocked, then the traction means placed around the object, the closing lever closed and finally blocked.

The locking device described consists of a few movable parts, which can be used as blocking elements identical parts. It is simply designed, but offers a complete mechanical solution that can secure the fixture against theft. The manufacturing cost of the locking device are low for these reasons.

Preferably, the actuator may be designed as a lock, so that the holding device is lockable and forms a useful anti-theft device together with the reinforcing element for the traction means.

The basic structure may have a connection pin for connection to the base. The connecting pin can be connected in a ball joint with the basic structure. If the connecting pin is connected to the base directly or via further connecting links, as preferred, so that it can no longer move relative to the base, the basic structure in the pivot joint which connects it to the connecting pin can be pivoted relative to the base in order to achieve an optimum position to take the connection with the object. In this case, the basic structure in the rotary joint about the longitudinal axis of the connecting pin can be rotated by 180 °, transverse to the longitudinal axis, the basic structure can be pivoted by an angle which depends significantly on the geometry of the connection in the ball joint, preferably between 25 ° and 40 °, more preferably between 28 ° and 32 °. This freedom of movement allows individual adaptation to a wide variety of objects to avoid damage, for example.

The inclusion of the basic structure may form an elastic abutment for the article and be elastically compressible for tensioning the traction means. In this case, the receptacle itself may at least partially consist of an elastic material or the receptacle may be connected via an elastic element to the basic structure. This elastic element may be an elastic layer or a spring, for example one or more leaf spring (s) or spiral spring (s). The elastic thrust bearing can give way when tensioning the traction device and compensate for any slight relaxation of the traction means occurring after the clamping by the construction of the clamping lever. Instead of or in addition to the recording and the traction means can be elastically compressible transversely to the pulling direction. For example, the traction means may have an elastic layer on the side facing the basic structure or may be connected to an elastic layer.

The basic structure may be a torsion-resistant, preferably a shell structure of, for example, plastic. This shell structure may for example consist of a shell body and a lid. The shell body may have a bottom and side walls or a side wall, wherein the holding elements for the clamping lever, the joint element for connection to the clamping lever, the pivot element for the connecting device are preferably formed on the outside of the side wall and the sidewalls and the mechanism of the locking device in the shell body or is arranged inside on the bottom of the shell body. The cover may have an opening for a tool for moving the adjusting element of the locking device or a lock, via which the adjusting element moved and the holding device can be locked.

A first preferred application for the holding device is the attachment of bicycles to bicycle holders. The holding device can be adjusted individually to each bicycle frame. Especially with electric bikes this mobility of the basic structure relative to the base is advantageous since the power cables are often attached to the frame of the electric bike and can be prevented by exact positioning of the basic structure to the bicycle frame a displacement or damage to the cable.

A second likewise preferred field of application lies in the field of health care. There, the holding device according to the invention can be advantageously attached for attaching cannulas, cannula holders, bottles with drugs and other objects to a base, such as a hospital bed or a hospital room wall.

In the following, we will explain the invention with reference to figures in an exemplary embodiment. Features that can be taken from the figures form each individually or in any combination of features, the subject of the claims and also the embodiments described above advantageous.
