Device for attachment to a leveling bar with variable height adjustment

Abstract

Device for attachment to a levelling bar or a similar levelling tool for uniform height control during levelling operations, comprising: o a main plate (Fig. 1) with elongated holes (6) for variable height adjustment, o a holding plate (Fig. 2) with holes (8) for fixing, o Fastening elements (9) (Fig. 3) such as screws, clamping levers or similar fastening means for fixing the device to the levelling board, o a shaft (7) (Fig. 1), which serves as a stop element and onto which additional modules such as rollers (Fig. 4) or skids (Fig. 5) can be pushed and fixed, o wherein the main plate is arranged so that it can be adjusted to different height levels by loosening and fixing the fastening elements (9).

Description

Introduction:

[0001] This device is designed to be attached to a leveling bar to level materials such as bulk materials, screed, or concrete with millimeter precision. Its variable height adjustment allows for flexible adaptation to different layer thicknesses and floor conditions. Technical description:

[0002] The device includes the following main components: 1. Main plate ( Fig. 1) with elongated holes (6) for variable height adjustment and shaft (7). 2. Holding plate ( Fig. 2), which serves as a counter element for fixing to the leveling bar. 3. Fastening screws (9) ( Fig. 3) for fixing to the leveling bar. 4th Wave (7) ( Fig. 1), to the additional modules such as skids ( Fig. 5) or roles ( Fig. 4) can be pushed on and fastened. 5. Holes (8) in the retaining plate ( Fig. 2) to fix the main plate. 6. Optional rubber or plastic covering that provides slip resistance and protection for the screed. How it works: • The main plate ( Fig. 1) is attached to the leveling bar with screws, clamping levers, etc. (9). • The height can be flexibly adjusted using the elongated holes (6). • The device can be reversed or adjusted as required. • The Wave (7) ( Fig. 1) can be used as a stop or as a holder for rollers ( Fig. 4) or skids ( Fig. 5) serve. Special features of the device: 1. Permanent or temporary attachment: The device can remain permanently installed on the leveling bar. When in use, it can be screwed on so that the shaft (7) is outside the leveling bar. When not in use, the device is turned over and secured with the shaft (7) inside the leveling bar, so that the normal function of the leveling bar is not affected. 2. Flexible height adjustment: Continuously adjustable through elongated holes without the need for additional parts. 3. Optimized force distribution: The holding plate ensures even pressure distribution on the screed. 4. Extensibility: The Wave (7) ( Fig. 1) allows the attachment of additional modules such as skids ( Fig. 5) or roles ( Fig. 4). 5. Robust construction: Designed for construction site use, durable and robust. 6. Easy installation: Minimal intervention in the leveling bar (only two holes required). Advantages of the device: • Firm and secure mounting on the leveling bar • Always at hand when needed • Always findable, as it has a fixed location • Precise and flexible height adjustment • Large-area pressure distribution to protect the leveling bar • Easy to use without special tools • Robust construction for rough construction site use • Further usage options through additional adapters etc. Areas of application:

[0003] The device is suitable for all work that requires precise surface finishing, including: • Stripping of concrete, screed or sand bedding • Paving work in gardening and landscaping • Road and path construction Comparison to existing solutions:

[0004] Unlike separate clamping systems, which are often lost or require complicated installation, this device remains firmly attached to the leveling bar. This means it's always ready for use and saves valuable working time.

Claims

[1] Device for attachment to a levelling bar or a similar levelling tool for uniform height control during levelling operations, comprising: o a main plate ( Fig. 1) with elongated holes (6) for variable height adjustment, o a holding plate ( Fig. 2) with holes (8) for fixing, o Fastening elements (9) ( Fig. 3) such as screws, clamping levers or similar fastening devices for fixing the device to the levelling board, o a wave (7) ( Fig. 1), which serves as a stop element and to which additional modules such as rollers ( Fig. 4) or skids ( Fig. 5) can be pushed on and fixed, o wherein the main plate is arranged so that it can be adjusted to different height levels by loosening and fixing the fastening elements (9). [2] Device according to claim 1, o The shaft (7) can be rotatable or fixed, so that it serves both as a height stop and as a fastening point for further modules. [3] Device according to claim 1 or 2, o where the main plate ( Fig. 1) is supplemented by an anti-slip base made of rubber, plastic or a similar material. [4] Device according to one of the preceding claims, o the device is designed so that it either remains permanently attached to the levelling board or can be brought into a rest position by simply turning it. [5] Device according to one of the preceding claims, o where the shaft (7) ( Fig. 1) has a modular system for assembling various additional components, including: ▪ Roles ( Fig. 4) to facilitate movement along a reference profile, ▪ Skids ( Fig. 5) to bridge uneven height differences on the reference surface so that the leveling bar does not sink into recesses and a uniform height control is guaranteed. [6] Device according to one of the preceding claims, wherein the fastening screws (9) ( Fig. 3) are designed in such a way that they allow the device to be loosened and adjusted without the use of tools.
