Description

[0001] The present invention relates to a roller adapter for a fence element, in particular for a mobile fence element or construction fence element, comprising a holder and a roller arranged on the holder, wherein the holder has a receiving element for receiving a, in particular first, frame element of a fence element and a securing element for securing a, in particular first, frame element received in the receiving element. The invention further relates to a fence element comprising such a roller adapter. Technological background

[0002] Fence elements are generally used as modular components for enclosing properties, demarcating areas, or securing premises. They are often made of materials such as metal, wood, plastic, or composite materials and come in various designs, including barred fences, chain-link fences, picket fences, and privacy fences.

[0003] Roller adapters are used to pivot and guide movable fence elements, such as gates, within a fence system. Roller adapters are usually not integrated with the fence elements but can be attached as needed. In the prior art, roller adapters for fence elements, especially for temporary or construction fences, are typically designed to include a roller and a holder that is attached to a frame element of the fence. The roller adapter is usually attached to the fence element using screws, nuts, or similar fasteners, requiring the use of tools such as wrenches, pliers, or similar implements.

[0004] This complicates the assembly and disassembly of such roll-up adapters, as the appropriate tool is required for each step. Especially on construction sites or with temporary barriers, where mobile fences are frequently used, quick assembly and disassembly are of great importance. Description of the invention: Problem, solution, advantages

[0005] The invention aims to provide a roller adapter for a fence element, which can be attached to a fence element easily and quickly.

[0006] To solve the problem, a roller adapter for a fence element, in particular for a mobile fence element or construction fence element, is proposed, comprising a holder and a roller arranged on the holder, wherein the holder has a receiving element for receiving a, in particular first, frame element of a fence element and a securing element for securing a, in particular first, frame element received in the receiving element, wherein it is further provided that the securing element can be attached and / or fixed to the receiving element without tools.

[0007] The roller adapter is designed to equip a fence element, such as a temporary or construction fence panel, with a roller to facilitate its movement, for example, to position a gate within a group of fence elements. For this purpose, a roller is mounted on the holder, enabling smooth movement of the fence element. The holder includes a receiving element designed to accommodate a frame element of the fence panel. The receiving element is designed to securely hold the frame element. To this end, the receiving element preferably forms a receiving area for the frame element and has an insertion area for inserting the frame element into the receiving area.

[0008] A locking element is provided to secure a frame element inserted into the receiving element. Securing a frame element inserted into the receiving element means preventing it from being pulled out through the insertion area of ​​the receiving element. Thus, the locking element prevents the frame element from unintentionally coming out of the receiving element. The locking element is designed to be attached and / or fixed to the receiving element without tools. This allows for quick and easy assembly and disassembly of the roll adapter on the fence element. Tool-free attachment and / or fixing means attaching or fixing the locking element to the receiving element manually, without the use of any additional tools or aids.The tool-free fastening also contributes to user-friendliness and flexibility when used on construction sites or for temporary barriers. The locking element can be attached and / or fixed to the mounting element in such a way that it does not detach from the mounting element during normal use of the roller adapter. When the locking element is attached and / or fixed to the mounting element, a frame element inserted into the mounting element is secured.

[0009] The roller adapter can also be called a construction fence roller or wheel.

[0010] The roller can be arranged on the holder so that it can rotate around a vertical axis when used as intended.

[0011] It may be provided that the frame element is a tube or a rod, in particular a round tube or a round rod.

[0012] However, it is also conceivable that the frame element has a different cross-sectional shape, for example, a polygonal one. Fence elements, especially temporary fence elements or construction fence elements, usually have a frame made of four tubes or poles welded together at right angles. Within the area enclosed by the frame, rods extending between the tubes or poles and welded to them are arranged.

[0013] Preferably, the receiving element may have a base and two legs extending from the base, and / or the receiving element may be essentially U-shaped.

[0014] The two legs can be arranged to laterally encompass the frame element to be received, while the base serves as a mounting or support surface for the frame element. It is also conceivable that the receiving element is designed in other, for example, modified, geometries, provided that secure reception of the frame element remains guaranteed.

[0015] Preferably, the legs of the receiving element are aligned largely parallel to each other and connected via the base. The ends of the legs opposite the base form free ends, between which an insertion area is formed for inserting a frame element into a receiving area formed in the region of the base between the legs.

[0016] The mounting element can be welded to the holder, for example, or alternatively formed from it. In particular, the legs can be manufactured by forming the holder's material. These manufacturing methods enable a robust and durable connection between the mounting element and the holder, as well as high stability for the entire roller adapter.

[0017] Furthermore, it can be provided that the receiving element is a clamp or a bracket, preferably a U-clamp or a rectangular clamp or a U-bracket or a rectangular bracket, more preferably a flat steel clamp or a flat steel bracket.

[0018] The clamp or bracket can be designed to grip the frame element at least from below and from the side. The choice between a U-shape or a rectangular shape can depend on the cross-section of the frame element being mounted, allowing for optimal adaptation to different fence elements. Similarly, a flat steel clamp or bracket design can facilitate the relative alignment of the roller adapter and the fence element.

[0019] The clamp or bracket can alternatively also be referred to as a retaining clamp or retaining bracket.

[0020] It is further preferably provided that the legs, in particular those arranged in the free ends of the legs, have openings or penetrations, wherein the securing element for securing a frame element received in the receiving element, in particular a first frame element, can be guided or is guided through the openings or penetrations.

[0021] The locking element can be passed through these openings or passages to secure a frame element, particularly the first one, that is inserted into the receiving element. This prevents the frame element from unintentionally sliding out of the receiving element. Especially when the legs are essentially parallel, it is possible to pass the locking element through the openings or passages of both legs.

[0022] It is also conceivable that the legs each have several openings or cutouts to allow for variable positioning of the locking element. This allows the roller adapter to be adapted to different frame element diameters or geometries.

[0023] Preferably, it may be provided that, when the locking element is guided through the openings or penetrations of both legs, the base, the legs and the locking element together form a circumferentially, approximately ring-shaped, closed eyelet in which the frame element is held.

[0024] Preferably, the openings or holes can be designed as round holes or as oblong holes.

[0025] For example, it is conceivable that a round hole is provided at each free end of the legs, through which a locking element, such as a pin or bolt, can be inserted. Similarly, elongated holes can be used instead of round holes to allow for flexible positioning of the locking element or to compensate for tolerances. Furthermore, in fence elements where bars are welded to the frame elements forming the frame, such as pipes or poles, the position of the attachment points of the bars to the frame elements may necessitate flexible positioning of the locking element.

[0026] It is also possible to provide a combination of round holes and oblong holes, for example by having one leg with a round hole and the other with an oblong hole.

[0027] Furthermore, the locking element may comprise a plate, a pin or a bolt, or be a plate, a pin or a bolt wherein the plate, pin or bolt has a collar or head at a first end and a hole at an end opposite the first end.

[0028] A plate, pin, or bolt can be inserted and positioned particularly easily and reliably through corresponding round or elongated holes in the legs of the receiving element. Furthermore, when the locking element is guided through the openings or perforations in the legs of the receiving element, the collar or head can rest against an outer edge of one of the legs surrounding the opening or perforation. This prevents the locking element from sliding completely through the opening or perforation in the leg and ensures secure positioning of the locking element. The hole at the opposite end can, for example, accommodate a locking device to secure the locking element against unintentional loosening.

[0029] The locking element, in particular the plate, pin, or bolt, can be made of metal, plastic, or another suitable material. The choice of material depends on the requirements for stability, corrosion resistance, and durability in the respective application.

[0030] Preferably, the locking element may include a locking means, wherein the locking means can be guided through the hole of the plate, pin or bolt.

[0031] By inserting the locking device through the hole at the end of the plate, pin, or bolt opposite the collar or head, the locking element can be secured against unintentional loosening or falling out of the arms of the receiving element. The locking device can be attached and removed without tools, further simplifying the handling of the roller adapter and enabling quick assembly and disassembly.

[0032] The locking mechanism can be made of metal, plastic, or another suitable material. The choice of material depends on the requirements for stability, corrosion resistance, and durability in the specific application.

[0033] It can be designed so that, after insertion through the hole in the plate, pin, or bolt, the locking device rests against the outside of one of the legs of the receiving element. This prevents the locking element from being pulled out of the openings or through-holes in the legs. The external placement of the collar or head and the locking device on the legs ensures particularly secure fixation of the locking element, especially the plate, pin, or bolt, to the receiving element. The locking device can be easily and quickly removed to release the locking element and detach the roller adapter from the fence element.

[0034] It may be provided that the locking device is a clamp or a cotter pin, in particular a spring cotter pin.

[0035] The use of a clip or cotter pin allows for particularly simple and quick tool-free securing of the locking element to the receiving element. A spring cotter pin, for example, can be designed as a bent wire with a spring action that, after being inserted through the hole, remains in position on its own, thus ensuring reliable locking. Alternatively, the locking device can also be designed as a spring pin or retaining ring.

[0036] Preferably, the holder may have a holding element for holding a second frame element of a fence element, in particular arranged at right angles to the first frame element.

[0037] The retaining element can serve to hold and secure a second frame element of the fence panel. Preferably, the second frame element is arranged at right angles to the first frame element, so that the roller adapter can be reliably attached, particularly at a corner of a fence panel.

[0038] The retaining element can be designed to provide a positive-locking and stable connection between the roller adapter and the second frame element. It is also conceivable that the retaining element is available in different geometries or sizes to accommodate various frame elements.

[0039] The retaining element can be welded to the holder. Preferably, however, the retaining element is formed in one piece, particularly in one piece of material, with the holder and molded from it.

[0040] The receiving element, together with the retaining element, can serve to hold frame elements of a fence panel arranged at right angles to each other. These frame elements are preferably connected to each other at the corners of the fence panel, in particular by welding. By simultaneously holding the frame elements arranged at right angles to each other, the roller adapter can be positioned or fixed to the fence panel with particular security. This helps to prevent the roller adapter from slipping during use and ensures reliable guidance and movement of the fence panel.

[0041] In another possible embodiment, the retaining element can be a retaining bracket, in particular a U-shaped one, wherein the retaining bracket has two legs connected to each other via a central section, with a hole for the passage of the second frame element arranged in each of the legs.

[0042] This design allows the second frame element, which is preferably positioned at right angles to the first frame element, to be guided securely and securely within the retaining bracket. The arrangement of the holes in the legs can be chosen so that the second frame element fits precisely and a stable connection between the roller adapter and the fence element is ensured.

[0043] Alternatively, the retaining element can be designed to correspond to the receiving element. In this case, the retaining element can, for example, also be designed as a clamp, bracket, or in another suitable form. It is then possible to provide a further securing element to secure a second frame element received in the retaining element.

[0044] Another solution to the problem consists of a fence element, in particular a mobile fence element or construction fence element, which includes a roller adapter described above.

[0045] The fence element can be used, for example, as a temporary barrier on construction sites, at events, or to secure properties.

[0046] The fence panel typically has a frame structure composed of several frame elements, such as tubes or poles. These frame elements can be arranged at right angles to each other and connected at the corners, for example, by welding or bolting. The roller adapter is attached to the fence panel in such a way that its receiving element engages with a frame element of the fence panel. The tool-free attachment of the locking element to the receiving element allows for quick and easy installation and removal of the roller adapter from the fence panel.

[0047] The fence element may also have additional features, such as connecting elements for linking several fence elements, feet, reinforcing struts or devices for holding privacy screens. Brief description of the characters
