System for retrofitting existing double wire fences with safety features using holders made of aluminum, steel or plastic

Abstract

Retrofit system for mesh panel fences, characterized in that this new mesh panel with a width deviating from the norm of approximately 2,550 mm is designed in such a way that it can be connected overlappingly to an existing mesh fence system of a first type, wherein the holders are attached to existing fence posts without replacing or structurally altering them.

Description

Technical description -

[0001] System for retrofitting existing double-wire fences with aluminum, plastic, or steel brackets for enhanced security. Overlapping mesh panel with increased safety function. Technical field:

[0002] The invention relates to the field of fencing systems, in particular mesh fences made of double-wire mesh panels, as used in industry, in the private sector, or for critical infrastructure. The invention relates to a mesh element with overlapping mounting for retrofitting existing fencing systems to increase security. State of the art:

[0003] Double wire mesh panels with a standard length of maximum 2500 mm are typically mounted on posts with aluminium, plastic or steel brackets.

[0004] The brackets are located on the front of the fence posts; the mats are placed on top and secured in the middle with a screw and flat iron or stainless steel brackets to prevent them from falling out. Fig. 3)

[0005] If a horizontal force acts on the fence and its brackets, the brackets will tear off, break, or bend, the mesh panels will slip out, and access to the property will be gained. The centrally located screw serves no purpose in this case, as there is no secure, positive connection between the mesh panel and the screw.

[0006] The grilles are only secured against falling out forwards.

[0007] Currently, it is not possible to mount a combination of overlapping mesh panels and brackets (aluminum, plastic, or steel) to existing fence posts. All previously used...

[0008] Fence systems are not compatible with each other. The post spacing differs between all systems. Plastic brackets lose their stability over the years.

[0009] Customers want an environmentally friendly and sustainable alternative fastening method. This can also be achieved with this system. Purpose of the invention: 1. Posts already mounted with aluminium, plastic or steel holders can be retrofitted without replacing the posts embedded in concrete. 2. Plastic holders that have deteriorated due to environmental influences can be omitted; the grids can be screwed directly in place with a force-fit connection. 3. The screw now prevents it from slipping out sideways. 4. A significant increase in fence security is made possible by overlapping the grid. 5. Particularly suitable for subsequent use in critical areas (e.g. prisons, logistics, railways, military, energy facilities). Solution to the problem: The invention consists of a modified double-wire mesh mat with a total length of approximately 2555 mm (+ / -2 mm), Mesh size of approximately 50 × 200 mm. The unique feature of this mesh panel is that the two outermost sections each have a single horizontal wire at every 200 mm. On the right side of the panel, this wire is located at the front, and on the left side, it is located at the back. This ensures that two adjacent fence panels can be installed, forming a defined overlap area to the left and right of the screw. The existing brackets can remain on the posts or be removed.

[0010] This combination and these dimensions are technically new, even if some of the individual parts are not. REFERENCE MARK LIST 1 mesh mat holder 2 screws 3 Grid overlap horizontal wire front 4 Grid overlap horizontal wire at the back 5 posts 6 vertical wires 7 Clamping part

Claims

[1] Retrofit system for mesh panel fences, characterized by , that this new mesh panel with a non-standard width of approximately 2,550 mm is designed in such a way that it can be connected in an overlapping manner to an existing mesh fence system of the first type, whereby the holders are attached to existing fence posts without replacing or structurally altering them. [2] Retrofit system according to one of the preceding claims, characterized by that the installation is carried out without additional foundation work and without the use of new fence posts or additional building materials such as concrete. [3] Retrofit system according to one of the preceding claims, characterized by , that this double wire mesh panel overlaps with an adjacent left and right mounted mesh panel in such a way that an overlap of approximately 28 mm is created at the post and the securing screw forms the center point. [4] Retrofit system according to one of the preceding claims, characterized by that the fasteners are made of metal, plastic, aluminum or a combination of these materials and are designed to be replaceable or retrofittable. [5] Retrofit system according to one of the preceding claims, characterized by that it can be used both for retrofitting existing fence systems and for extending newly erected fence systems. [6] Retrofit system according to one of the preceding claims, characterized by that the system is modular and adaptable to different fence heights and types without requiring individual custom manufacturing. [7] Retrofit system according to one of the preceding claims, characterized by that it is suitable for both security applications (e.g. kindergartens, industrial plants) and private property enclosures. [8] Grid mat according to one of the preceding claims, characterized by that no dismantling or relocation of the existing posts is required. [9] Grid mat according to any one of the preceding claims, characterized by that the overlap creates a force-fit connection with increased tensile strength
