Description

The The invention relates to an extendable axle for electronic Locking systems - in particular for electronic Lock cylinder.

electronic lock cylinder usually have one Cylinder body, one in the cylinder body guided from the outside through the door leaf to the inside extending axis, a cam for actuating a Mortise lock, an inside and / or an outside handle, an electric drive, an electronic control unit and a battery.

electronic lock cylinder especially on doors used where they allow the in the doors existing mortise locks to press. The length the built-in lock cylinder should correspond to the respective door thickness, because the cylinders for safety reasons and also from aesthetic establish preferably not out the door to stand out. That's why electronic lock cylinder different lengths be offered on the market. It has become naturalized that manufacturers electronic lock cylinder offer their products in different lengths, with the length extension usually each in 5 mm increments. The products must be from the trade in a defined length ordered, not only the total length must be considered, but also their division into the two partial dimensions "from the forend screw outside "and" from the forend screw inside ".

Of the finished lock cylinder is only for one certain door thickness with defined division of these two partial dimensions can be used. This has to Result that the trade finished lock cylinders of different Length and Distribution must be kept in stock if customer needs without longer order time wants to serve. Since the trade the high financing costs of a such storage usually does not want to carry leads This is because electronic lock cylinders normally only ordered according to customer needs. This has the extra Disadvantage that the dealer first once at the door End user endeavor must be to the mounting dimensions of the lock cylinder measure.

Around avoid the disadvantages, it would be advantageous to an electronic To be able to offer cylinders the one in length is variable and thus during assembly to the concrete installation situation the concrete door can be adjusted. It would be particularly advantageous if the adaptation so would be easy that the average craftsmanship of end users so not overwhelmed would.

In the DE 198 34 692 A1 is described the extendable axis of an electronic lock cylinder. This locking system is with an inside and outside handle 10 . 50 equipped, with the handles are equipped with control electronics and electric drive. The total axis consists of two axle parts 12 . 52 , Both axle parts are obviously fixed against axial displacement in each case on a handle. They are guided into each other and by pulling a length variation of the overall axis can be made possible.

The presented solution has two disadvantages. A first disadvantage is that the total length is limited. The maximum length is reached when the two axle parts to the stop apart are drawn. The second disadvantage is that the axis is in the inside handle protrudes into and thereby the use of the cavity limited in the inside handle.

In the DE 680 417 A a principle is presented to adapt a cylinder lock by skillful training a hollow shaft (support tube) to different door thicknesses. On the support tube axle parts are attached, which are rotatably connected with each other. A disadvantage of this solution is that the support tube must be sawed off for length adjustment. This is very disadvantageous if a connecting cable is to be guided in the support tube, since this can be damaged very easily during sawing.

In the DE 100 45 492 A1 A system with stepless door strength adjustment of the axle is presented. The outer rotary knob integrates a reading unit for electronic keys.

A with the outside knob connected axis leads through a cylinder adapter to the inside of the door and carries there an electrically controllable locking system. In a rigidly fixed Inner axle run connecting wires from the reading unit to the inside control electronics. Both axes have excess length and can inside of the door cut become. This is a stepless adjustment to different Door thicknesses possible.

This Proposal, however, does not describe any real electronic Lock cylinder, but a small electronic hardware in which both outside and outside inside electrical components mounted in fixed rosettes are. Such a fitting is subject to certain installation restrictions, because he fits with his rosettes to the existing equipment of the door got to.

aim It should be the invention, an actual electronic lock cylinder in variable length execution to describe where all needed Components in the cylinder body, are arranged in the axis or in the two rotatable handles, so that neither on the outside still on the inside permanently mounted components in rosettes are needed. If such a system during assembly to individual door thicknesses adaptable have to be both cylinder body as well as axis length variable be designed.

Of the variable length cylinder body is described in a parallel font of the applicant. In the This font will now describe the variable length axis become.

• 1. Es soll im Standard-Türstärkenbereich von 60 mm bis 90 mm eine stufenlose Längenanpassung der Achse oder zumindest eine Anpassung in 5-mm-Schritten möglich sein.
• 2. Die vorgenommene Längenanpassung muss reversibel sein: es muss in einfacher Weise möglich sein, die Achse wieder zu demontieren und sie dann auf eine andere Länge anzupassen
• 3. Das für Zusammenbau und eventuelle spätere Demontage benötigte handwerkliche Geschick darf das durchschnittliche handwerkliche Können von Endverbrauchern nicht übersteigen.

The object of the invention is to describe a length-adjustable axle for electronic lock cylinders, which is suitable for distribution in do-it-yourself assortment for end users. This task has three requirements:

• 1. It should be possible in the standard door thickness range of 60 mm to 90 mm, a stepless length adjustment of the axis or at least an adjustment in 5-mm increments.
• 2. The length adjustment made must be reversible: it must be easy to disassemble the axle and then adjust it to a different length
• 3. The manual skills required for assembly and eventual disassembly must not exceed the average skill level of end users.

The Tasks are fully covered by the measures indicated in claim 1 Fulfills. The marked measures describe an embodiment which allows a gradual adaptation of the axis to the existing door thickness. The extra to be plugged Axles can in their length designed to be extensions in 5 mm increments possible become. The presented solution is reversible and requires only little craftsmanship.

By characterized in claim 2 measures is advantageously achieved that in the axis a cable or strands can be laid so that no damage can be done on rotation of the axis.

The characterized in claim 3 measures effect advantageous that the rotationally fixed connection of the axle parts already by the shape of the Parts is achieved, so that no additional entrainment elements are needed.

One embodiment The invention will be described below with reference to the drawing. Show it:
