The lance device 1 comprises an elongate flexible body 2 comprising a plurality of interconnected lane elements 3, and a tensioning means 4 extending Wigs with said flexible body 2 and adapted to provide a tensioning force adapted to fix said lane element 3 relative to each other. A welding mechanism (not shown) is adapted to adjust the tensioning force provided by the tensioning means 4, and maintain an undesired tensioning force. As shown in Figure 1, the lane elements 3 are arranged one after the other, each lane element 3 comprising at least one first cooperating surface 5 and at least a second cooperating surface 6, and the cooperating surfaces 5, 6 of two adjacent lane elements 3 are adapted to mutually cooperate with each other. when the exciting force is applied. Furthermore, each lane element 3 is rotatably connected to at least one adjacent lane element 3, and a plurality of the lane elements 3 are resiliently connected to adjacent lane elements 3.

In use, the lane device 1 has two states, a frame state and a detached state. In the tensioned state, a tensioning force of tensioning means 4 is applied so that the lane elements 3 are fixed relative to each other. Read the mechanism 7 (shown in figure 6) to ensure that the tensioning force is maintained. In the tensioned state, the elongate flexible body 2 is substantially rigid so that the lanyard device 1 can support different objects.

When the welding mechanism 7 is released, the cooperating surfaces 5, 6 are detached from each other so that the elongate flexible frame 2 becomes reshapable. The link device 1 is thus in a herring-loosened condition. The resilient connection between the lane elements 3 is advantageous in that the cooperating surfaces 5, 6 are quickly and easily detached from each other when the welding mechanism 7 is released.

As shown in Figures 2a-c, after a plurality of lane elements 3, at least one resilient element 8 adapted to disengage the first cooperating surface 5 from the second cooperating surface 6 in the sequence of lane elements 3 comprises, when the welding mechanism 7 is released.

According to one embodiment, more than 50% of the lane elements 3 comprise at least one resilient element 8. In another embodiment, however, each lane element 3 comprises at least one resilient element 8.

In one embodiment, the lance elements 3 are connected via pivots 9, where each lance element 3 comprises a pivot 9 and at least one pivot hall 10, as shown in Figures 2a-c. In Figures 2a-c, the resilient element 8 comprises a Most resilient pin 11 and a second resilient pin 12 adapted to suspend pivot pin 9 in cooperation with pivot neck 10. However, an obvious construction variant is that the resilient element 8 can comprise more than two resilient pins adapted. A first end 13 of the resilient pin is fixed to the hinge element 3 and the opposite spirit forms a supporting surface 14 adapted to the hinge pin 9. 3 537 856 Figures 2a-c also show that the hinge element 3 has a first cooperating surface 5 and a second cooperating surface 6. The first cooperating surface 5 and the second cooperating surface 6 comprise tooth-like projections adapted to interact with each other. Similarly, the cooperating surfaces 5, 6 can be provided with other matching monsters. According to another embodiment, the cooperating surfaces 5, 6 cooperate by friction, for example by providing said cooperating surfaces 5, 6 with a material which provides sufficient friction for fixing the lane elements 3 towards each other, such as rubber or soft plastics or the like.

According to the embodiment shown in Figures 2a-c, the first cooperating surface 5 is concave and the second cooperating surface 6 is convex. A first interconnecting portion 15a and a second interconnecting portion 15b extend from the concave cooperating surface 5, the first and second interconnecting portions 15a, 15b comprising at least one hinge pin 10 each. The first interconnecting part 15a and the second interconnecting part 15b can abut against further cooperating surfaces 33, 34 in the adjacent lane element 3, so that the interconnecting force between the lane elements 3 is further improved.

In another embodiment, as shown in Figure 3, the lane elements 3 comprise a plurality of first cooperating surfaces 5a, 5b and a plurality of other cooperating surfaces 6a, 6b.

According to the embodiment shown in Figure 6, the welding mechanism 7 comprises a rack gear device adapted to load the clamping wire and a clamping handle 24 adapted to adjust the clamping force acting on the clamping wire 4. The clamping force is increased by moving the clamping handle 24 up and down. In more detail, the welding mechanism 7 comprises a rack 25, a feeder 26, a spring-loaded ratchet 27 which is adapted to be released by pressing in a first button 28, and means 29 for lowering the clamping handle 24 when an undesired clamping force has been reached. The lowering of the clamping handle 24 is preferably performed by pressing a second button 30. However, the welding mechanism may also, as an obvious design variant, comprise any other suitable construction for welding and tensioning. In one embodiment, the clamping force is provided by the supply of the clamping means and the maintenance of the desired clamping force of the welding mechanism 7 takes place through a motor tensioner.
