Description

TECHNICAL TERRITORY

The The present invention relates to a closure device for joining two end portions of a recognition band, the connection only through destruction solvable is.

Serve identification bands to people or things for identify a specific period quickly and easily. For example, persons with such identification bands become who are authorized to enter at events. Such identification bands For example, they are also used to identify particularly privileged people People entering certain areas at events, for example allowed to, without the elaborate cards or ID checks are performed have to. The closure device for such detection bands must ensure that the identification tape remains with the authorized person and can not be exchanged. This is ensured by that the closure device only by destruction of the same or the recognition tape be solved can. In many cases become such bands around a body part a person so that stripping is not possible usually around the wrist, for example. This forms the folded band in conjunction with the closure device a closed ring.

• 1. Es wird kein Werkzeug zum Herstellen eines unlösbaren Verschlusses benötigt.
• 2. Weiterhin ist keine mechanische Verformung des Verschlusses nötig, um eine ausreichende Fixierung zu gewährleisten.
• 3. Darüber hinaus ist keine mechanische Funktion nötig, um den Verschluss herzustellen (zum Beispiel Umlegen einer Klappe oder Eindrücken eines Stiftes oder Einrasten eines Bügels wie bei den bekannten Verschlusseinrichtungen).
• 4. Die Sicherheit wird dadurch wesentlich erhöht, dass mehrere Verschlusseinheiten zu einer Verschlusseinrichtung zusammengesteckt werden können.
• 5. Durch das Vorsehen mehrerer Verschlusseinheiten ist eine Farbcodierung möglich, die zusätzliche Variations- und Unterscheidungsmöglichkeiten bietet.
• 6. Des Weiteren ist kein Kraftaufwand beim Anlegen des Bandes zum Verschließen notwendig, da ein einfaches Zuziehen der Verschlusseinrichtung ausreicht.
• 7. Weiterhin wird ein Einschnüren beispielsweise eines Handgelenks, an dem das Erkennungsband angelegt werden soll, dadurch vermieden, dass die Verschlusseinrichtung zur Arretierung des Erkennungsbands nach Einführung der Endbereiche des Erkennungsbands nochmals etwas zurückgezogen wird und daher eine Arretierung nicht an der engsten Stelle erfolgt, sondern durch Rückziehen des Verschlusses in die Widerhaken noch etwas gelockert wird. Dies erhöht den Tragekomfort.

The closure device according to the invention is distinguished from known closure devices by, inter alia, the following advantages:

• 1. No tool is needed to make a permanent closure.
• 2. Furthermore, no mechanical deformation of the closure is necessary to ensure adequate fixation.
• 3. In addition, no mechanical function is necessary to make the closure (for example, flipping a flap or pushing a pin or latching a strap as in the known closure devices).
• 4. The security is significantly increased by the fact that several closure units can be put together to form a closure device.
• 5. By providing a plurality of shutter units, a color coding is possible which offers additional possibilities of variation and differentiation.
• 6. Furthermore, no effort is required when applying the tape for closing, since a simple closing of the closure device is sufficient.
• 7. Furthermore, a constricting, for example, a wrist on which the detection tape is to be applied, thereby avoided that the closure device for locking the recognition tape after insertion of the end portions of the recognition tape is again slightly withdrawn and therefore locking does not take place at the narrowest point, but by loosening the closure in the barbs is still slightly loosened. This increases the wearing comfort.

Further embodiments and advantages of the invention will be apparent from the claims listed Characteristics and by the embodiment given below. The features of the claims can be combined in any way as far as they are concerned not obviously mutually exclusive.

WAYS TO EXECUTE INVENTION

In the 1 and 2 is an embodiment of a closure device 10 with a locking unit 14 shown.

The closure unit 14 is as a circular hollow section with an inner wall 18 and an outer wall 28 educated. The closure unit 14 is rotationally symmetrical to its longitudinal axis 30 educated.

On the inner wall 18 are arranged circumferentially offset by 90 ° barbs elements 16 molded, which slopes upwards into the interior of the closure unit 14 protrude, wherein the cross-sectional dimensions decrease linearly towards the top.

In the upper end area 20 the locking unit 14 has the inner wall 18 an upper return 24 on, leaving the top end area 20 has an inner dimension I, compared to the normal inner diameter of the inner wall 18 is enlarged.

In the upper end area 20 opposite lower end region 22 has the outer wall 28 a lower return 26 on, that is the lower end area 22 has an outer dimension A, which is opposite to the outer diameter of the outer wall 28 is formed reduced.

The inner dimension I of the upper end area 20 is dimensioned so that it is slightly smaller than the outer dimension A of the lower end portion 22 , This makes it possible that in the direction of the longitudinal axis 30 several closure units 14 can be put on each other, each with the upper end 20 a closure unit 14 with the lower end area 22 an adjacent closure unit 14 comes in clamping engagement, creating a clamping connection between the two closure units 14 given is.

The insertion direction of end areas of an in 1 Detection bands, not shown, are indicated by the arrow E.

The 3a shows a closure device 10 in which two closure units 14 . 14.1 are stacked on each other. The 3b shows a closure device 10.2 , at the three closure units 14 . 14.1 . 14.2 are stacked on each other.

4 shows in a schematic perspective a recognition tape 12 which is closed into a ring, wherein the end portions of the recognition band 12 through a closure device 10.1 be fixed, the two successive closure units 14 . 14.1 having. To fix the recognition tape 12 For example, on a wrist first the two end portions of the recognition band 12 in the insertion direction E into the interior through the closure units 14 . 14.1 guided, so that initially a loop is formed, which can still be easily striped over a hand. Thereafter, the end portions are further pulled in the insertion direction E until the loop of the recognition tape is more or less on the wrist. Subsequently, the closure device 10.2 shifted short against the insertion direction E relative to the end portions of the recognition band, so that the barb elements 16 within the locking units 14 . 14.1 in the end area of the recognition band 12 penetration. One with its end portions through the closure device 10.1 performed identification tape 12 can no longer counter to the insertion direction E from the closure device 10.1 be pulled out. A release of the recognition tape 12 from the wrist is only possible if the detection tape 12 in the area of the closure device 10.1 is violently pulled against the insertion direction E destroyed or cut in the loop area.
