Abstract

Flexible, double-sided toothed belt for shafts and tubes, characterized in that it has an external toothing 04, in any module, for transmitting rotational movements to a tube 12.

Description

The invention relates to a flexible, double-sided toothed belt for shafts and tubes, designed as a plastic strip in any length and width, which externally has a drive toothing in any module and inside via a locking toothing, and a closure head for threading and clamping around cylinder with any diameter ,

It is known that timing belt in conjunction with discrete clamping devices for retrofitting of tubes, such. As zoom and focus rings on camera lenses, can be used to retrofit them with a sprocket for mechanical or motorized actuators. Such a device was, for example, with the utility model DE 20 2009 004 578 U1 announced on 27. 08. 2009. Furthermore, on the market different lengths, provided at both ends with eyelets toothed belt sections of different design and offered by different manufacturers, which are to be threaded into the eyelets to be stretched, separate cable ties.

The disadvantage of such devices is the complex construction with discrete components, such as clamping blocks, clamping screws, cable ties, etc., the inconvenient handling and that the latter type, depending on the cylinder radius, must be made in different lengths variants. In addition to the manufacturing costs and the compulsory range of the manufacturer, there is a risk that the user still does not always have the required length at hand.

Here, the invention remedy by providing a flexible plastic tape, which is provided on its outside with a gear teeth arbitrary module and on the inside page with a locking toothing as cable ties, and a closure head can be wrapped around a tube of any diameter. For assembly, the free end of the band is placed around the tube and threaded into the closure head, which has a nose with counter-locking notched teeth, and pulled taut without any use of tools. After snapping the inner locking teeth of the band also ensure a secure grip on the usually rubber-reinforced surface of the tube, with their small tooth spacing allows a precisely metered voltage.

The length of the tape is determined by the largest tube circumference of the field of application, z. B. for camera lenses determined. The protruding end of the tape is cut off after assembly. The significantly lower production costs for the uniform injection-molded part, it suggests, each lens permanently equipped with its own dental tape.

The adjustable angle of rotation for the tube is limited only by the size of the closure head after attaching the ring gear.

For special applications, eg. As to camera lenses, which are equipped because of the optional operation in autofocus mode with a slip clutch in the lens ring for image sharpness and thus have no fixed end stop with manual Fokussierungsweise, can be slid on the lateral guide rails of the band, lockable tabs as stop points for Drehwegbegrenzung be prevented in order to prevent that each of the maximum sharpness-adjusting effective angle of rotation is exceeded, while the fixed reference to the actuator is lost. These optional tabs either run on the driving sprocket or are stopped by a tactile nose attached to the lens.

The subject invention of the innovation presented here is not limited to the embodiments shown and results not only from the individually enumerated protection claims, but also from the combination of these with each other and the many conceivable variants. All embodiments and their variants shown here in the description and the illustrations are, insofar as they are to be regarded as new with respect to the prior art, also claimed as essential to the invention.

The invention will be illustrated, described and explained with reference to an embodiment in the figures.

Here are the figures by way of example in detail:

1 shows the top view of the dental tape 01 from above, the gear teeth 04 , the threading bag 05 and the lock head 02 with the threading opening 03 ,

2 shows the dental tape 06 from below, as well as the delicate locking teeth 07 with the two lateral guide rails 08 ,

3 is a side view with the closure head 02 , the gear teeth 04 , the Rastverzahnung 07 and the lateral guide rails 08 ,

4 demonstrates the assembly process by the threading pocket 05 along the curve 13 around the tube 12 guided around and in the threading 03 is introduced.

5 provides the slide-on tab 14 for limiting the travel with the locking lug 15 represents.
