Abstract

Window opening sheet set for non-destructive opening of windows, characterized in that - the set consists of three sheets, - all sheets have a uniform thickness of 2 mm (2), - all sheets have a uniform depth of 50 mm, - all sheets have a uniform height of 30 mm at the ends, - the sheets have different widths at the ends (1, 3,4), and - the edges of the sheets are rounded

Description

[0001] The invention relates to a window opening plate set for the non-destructive opening of windows, in particular plastic windows with mushroom head locks. The set consists of three plates with a uniform thickness of 2 mm, a depth of 50 mm, and a height of 30 mm at the ends. The plates have different widths at the ends: the first plate 35 mm and 40 mm, the second plate 45 mm and 50 mm, and the third plate 55 mm and 60 mm. All plates are manufactured from a uniform total length of 333 mm and have rounded edges to prevent damage to the window. The invention enables effective and non-destructive opening of windows with a reduced set of only three plates, which simplifies handling and transport and reduces costs. ## Description### Technical area

[0002] The present invention relates to a set of three window opening plates used for the non-destructive opening of windows, particularly plastic windows with mushroom-head locks. The invention is applicable to the fields of security technology, key services, and emergency services. ### State of the art

[0003] Various tools for opening windows are known in the art. In particular, window opening plates such as the RESCOP window plates from Zieh-Fix are commercially available, which are offered in a set of six different lengths. These tools are primarily used by tradespeople, fire departments, locksmiths, and security services to open windows from the outside.

[0004] However, the conventional window opening plates have several disadvantages. Firstly, the number of plates required is relatively high (six), which makes handling and transport difficult. Secondly, the conventional plates are often not optimally adapted to the various window sizes and types, which limits their effectiveness. Furthermore, the edges of the plates can damage the window, especially the mushroom head lock, during use. ### Object of the invention

[0005] The invention is based on the object of providing an improved set of window opening plates which requires a smaller number of plates, enables optimal adaptation to different window sizes and ensures non-destructive opening of windows without damaging the mushroom head lock. ### Solution to the task

[0006] The task is solved by a set of three window opening plates, all of which have a uniform height of 30 mm at the ends but vary in width. All plates are 2 mm thick and 50 mm deep. The edges of the plates are rounded to prevent damage to the window and, in particular, to the mushroom head lock.

[0007] The first sheet has widths of 35 mm and 40 mm at the ends, the second sheet has widths of 45 mm and 50 mm, and the third sheet has widths of 55 mm and 60 mm. All three sheets are manufactured from a uniform total length of 333 mm, with the center lengths being calculated accordingly: 198 mm for the first sheet, 178 mm for the second sheet, and 158 mm for the third sheet. ### Advantages of the invention

[0008] The invention offers several advantages over the prior art: 1. **Reduced number of sheets**: Using only three sheets with different widths at the ends simplifies handling and transport. 2. **Optimal adjustment**: The different widths at the ends (35 / 40 mm, 45 / 50 mm, 55 / 60 mm) allow optimal adjustment to different window sizes and types. 3. **Non-destructive opening**: The rounded edges of the sheets prevent damage to the window and especially to the mushroom head lock. 4. **Efficient production**: All sheets are manufactured from a uniform total length of 333 mm, which enables efficient and cost-effective production. 5. **No retrieval function**: In contrast to some known solutions, the sheets according to the invention have no retrieval function, which simplifies handling and increases effectiveness. ### Example

[0009] An embodiment of the invention is described in the claim drawing ( Fig. 1). In the Fig. 1 is 1 (1) Left side part, (2) Thickness, (3) Center length, (4) Right side part, which is (5) Width and (6) Height of the edge.

[0010] All three sheets are made of steel and have a thickness of 2 mm (2) and a depth of 50 mm. The end height of all sheets is uniformly 30 mm (6). The edges of the sheets are rounded to prevent damage to the window, especially to the mushroom-head lock.

[0011] The first sheet has widths of 35 mm (1) and 40 mm (4) at the ends and a center length of 198 mm (3), resulting in a total length of 273 mm. The second sheet has widths of 45 mm and 50 mm at the ends and a center length of 178 mm, also resulting in a total length of 273 mm. The third sheet has widths of 55 mm and 60 mm at the ends and a center length of 158 mm, again resulting in a total length of 273 mm.

[0012] All three sheets are manufactured from a uniform total length of 333 mm, whereby the mean length is calculated by subtracting the final widths from the total length: ### Application of the invention

[0013] The window opening plates according to the invention are used for the non-destructive opening of windows, especially plastic windows with mushroom-head locks. Depending on the size and type of window to be opened, the appropriate plate is selected and inserted between the window frame and the window sash. The different widths at the ends allow the plate to be optimally adapted to the respective situation. The rounded edges prevent damage to the window and, in particular, to the mushroom-head lock.

[0014] The invention thus enables effective and non-destructive opening of windows with a reduced set of only three sheets, which simplifies handling and transport and reduces costs.
