Description

[0001] The invention relates to a mobile partition wall with a panel structure having a bullet-proof layer and with several rolling elements arranged at one end, according to the preamble of claim 1.

[0002] US 2018 / 0027958 A1 discloses a mobile partition wall mounted on a bulletproof lectern. At one end of the partition wall, rolling elements are arranged, which are attached to a support element and can be locked relative to it.

[0003] DE 198 46 161 A1 discloses a roller with a lifting device and a support device for securing it. At least one roller wheel can be raised and lowered via an eccentric lifting rod on the corresponding support arm.

[0004] EP 2 812 506 B1 discloses a panel structure for a demountable partition wall system that can be used to subdivide a room or to form rooms and / or corridors or other structures. The panel structure has two opposing main surfaces and a bullet-resistant center plate for a generally upright orientation. The panel structure is mounted on a base portion beneath which wheels are arranged. The wheels can be moved within the panel structure to move the wheels between a retracted position and an extended position. Raising and lowering the wheels serves to transport or move the panel structure. When the wheels are raised within the panel structure, the panel structure rests firmly with the base portion on the floor and remains there through friction.

[0005] Mobile partition walls are preferred for military training partition systems to create an environment suitable for offensive or defensive exercises. If live ammunition is also to be used, it is important to ensure that the individual panels are bulletproof. The resulting heavy weight of the partition walls complicates their mechanical handling, as they must be moved from one location to another when changing positions or during setup. The physical effort required for such heavy, robust military training partition walls is therefore considerable. Equipping the panel structure with several rolling elements that can be extended into a position touching the ground simplifies the panel structure's mobility.

[0006] However, it has proven disadvantageous that the wheels are subjected to heavy loads due to the weight of the bullet-proof panel structure, making it difficult to move. Depending on the type of floor, the wheels sink and can then only be moved with increased effort.

[0007] The object of the invention is therefore to create a mobile partition wall with a panel structure having a bullet-proof layer according to the preamble of claim 1, which is stable on the one hand and easily movable on the other.

[0008] This problem is solved by the features of claim 1.

[0009] This creates a mobile partition wall with a panel structure featuring a bullet-resistant layer. The weight is distributed via a manual lifting chassis with an outrigger system, in which a plurality of wheels can form a rolling support surface on one or both sides of the panel structure. The contact pressure per wheel can be reduced in this way. Preferably, each of the wheels can be lowered and raised again via a manually operated eccentric lifting rod. Manual operation enables individual raising and lowering of wheels, allowing each wheel to be individually controlled to a ground contact position. The eccentric lifting rod can also be used as an indicator device for the current status of a wheel—lowered / raised.

[0010] Further embodiments of the invention can be found in the following description and the dependent claims.

[0011] The invention is explained in more detail below with reference to the embodiments shown in the attached figures. Fig. 1 shows schematically a perspective side view of a mobile partition according to a first embodiment, Fig. 2 shows schematically a perspective side view of a mobile partition according to a second embodiment, Fig. 3 shows a plan view of the mobile partition according to Fig. 2, Fig. 4 shows a view of a wheel with raised roller, Fig. 5 shows a view of a wheel with the roller pressed down, Fig. 6 shows a section AA to Fig. 4, Fig. 7 shows a section BB according to Fig. 4, Fig. 8 shows the section Z after Fig. 4 partially cut, Fig. 9 shows the section Y after Fig. 5 partially cut.

[0012] How Fig. As shown in Figure 1, the invention relates to a mobile partition wall 1 comprising a panel structure 3 having a bullet-resistant layer 2. The panel structure 3 preferably has two opposing main surfaces 4, 5 and can be erected in a generally upright orientation during use. The erection can be carried out individually or with other such panel structures 3 in a system.

[0013] The panel structure 3 has a support end 6 on which several rolling elements 7 are arranged. The rolling elements 7 are arranged between an extended base 8 ( Fig. 4) a position contacting the space and a retracted or raised position. For this purpose, the rolling elements 7 comprise at least one wheel 10 actuated via a lifting mechanism 9. The operating characteristics of the panel structure 3 are thus maintained.

[0014] The rolling elements 7 are combined to form a multi-wheeled manual lifting chassis 11 with support arms 12 that are transverse to the panel structure 3 and project laterally relative to it. The support arms 12 each carry at least one running wheel 10 at their respective ends. The support arms 12 with the running wheels 10 arranged thereon form a boom system that, according to Fig. 1, for example, extends on one side of the panel structure 3 and preferably substantially parallel to a main surface 4.

[0015] The at least one running wheel 10 can be raised and lowered decentrally on the associated support arm 12 via an eccentric lifting rod 13 for the temporary rolling support of the panel structure 3 with a contact pressure per running wheel 10 for the weight distribution of the dead weight of the panel structure 3 on the floor 8 ( Fig. 4). The support arms 12 form quasi support legs, which extend from a support frame 14 formed by the manual lifting chassis 11. The panel structure 3 rests on this support frame 14 with its own weight. The support arms 12, which can be rigidly or pivotably attached to the support frame 14, have a projecting length relative to the panel structure 3 and are according to Fig. 1, for example, are designed as double-angled arms. The support arms 12 have a bearing 15 at their free end for holding and guiding a rolling element 7, here, for example, a running wheel 10.

[0016] How Fig. 2 and Fig. 3, the cantilever system according to the invention can be provided with support arms 12 and running wheels 10 mounted and guided thereon on both sides of the panel structure 3. A symmetrical arrangement of running wheels 10 on both sides of the panel structure 3 improves the weight distribution of the dead weight of the panel structure 3. Furthermore, the contact pressure per running wheel 10 can be additionally influenced by selecting the number of running wheels 10. According to the second exemplary embodiment, for example, six running wheels 10 with six associated support arms 12 per side are provided. The respective distance between the running wheels 10 can also be selected. The support arms 12 on both sides of the panel structure 3 are preferably arranged symmetrically and in a mirror image to the latter.

[0017] The Fig. 4 to Fig. 9 show in detail the lifting mechanism 9 using an eccentric lifting rod 13. For this purpose, for example, each support arm 12 is equipped with such a lifting mechanism 9. The bearing 15 then provided in each case comprises a guide tube 16 for attaching a running wheel 10, which preferably penetrates a support arm 12 vertically. A press ram 17 is guided axially through the guide tube 16 and engages with the associated running wheel 10, for example with a pressure plate 19 acting on a wheel axle 18. The press ram 17 is acted upon by an eccentric disc 20, which is pivotally mounted, for example, on side cheeks 21 fastened to the support arm 12. The eccentric lifting rod 13 is fastened to the eccentric disc 20 in order to pivot the eccentric disc 20 and thereby trigger a lifting path.

[0018] The stroke is used to push down the impeller 10, as in Fig. 5. In Fig. 4, the running wheel 10 is at the top, meaning that the panel structure 3 rests on the ground 8 under its own weight and remains there through friction. The support arm 12 is arranged such that a first section of the arm length forms a ground support section 22, which additionally supports the panel structure 3 laterally. A second section adjoining this section forms a type of wheel housing 23 for the running wheel 10.

[0019] Will, as in Fig.5, the eccentric lifting rod 13 is pivoted, the running wheel 10 is pressed down, and the panel structure is thus locally raised via the support arm 12, which engages the support frame 14. The floor support section 22 lifts off the floor 8. All support arms 12 arranged on the support frame 14 are preferably of the same design, as described above. Consequently, if all eccentric lifting rods 13 have been manually pivoted to push down a running wheel 10, the panel structure 3 is mounted on a rollable support. The support arms 12 form a floor-side cantilever system with reduced contact pressure per running wheel 10 when the panel structure 3 is lifted off the floor 8. The center of gravity is changed by widening the contact area.

[0020] Preferably, the respective eccentric lifting rod 13 has an actuatable lever rod, the rotational movement of which allows the eccentric disc 20 to perform a translational lifting movement.

[0021] Furthermore, a compression spring 24 can be provided, which guides the respective impeller 10 in the bearing 15 in a manner that can be subjected to compression spring action. The compression spring 24 prevents the impeller 10 from slipping during transport, ie, when raised. An anti-twist device can also be incorporated.
