Description

Technical Field

[0001] The utility model relates to the fields of building decoration and furniture manufacturing. In particular, an innovative connection processing method for solid wood handrails, columns and elbows in staircase design is proposed, aiming to simplify the installation process, improve the installation efficiency and aesthetics, and reduce the production and logistics costs at the same time. Background Art

[0002] When dealing with the turning of traditional solid wood staircase handrails, the methods of fabricating elbows on-site or prefabricating elbows in the factory and then installing them on-site are often adopted. Both of these methods have significant deficiencies, such as high construction difficulty, poor paint effect, high logistics cost, high installation precision requirements, and frequent after-sales problems. Content of the Utility Model

[0003] To overcome the deficiencies of the prior art, the utility model proposes a new connection processing method for solid wood handrails, columns and elbows of stairs, and its main features and innovations are as follows:

[0004] 1. Unified turning mechanism: For scissor-type stairs, a unified turning mechanism is designed. This mechanism can adapt to various directions such as left-starting turns, right-starting turns, upper-left flat turns and upper-right flat turns, and does not need to consider the specific slope and angle of the handrail. This design greatly simplifies the installation process and reduces the requirements for the skills of construction workers.

[0005] 2. Starting mechanism and ending mechanism: At the starting point of the staircase handrail, a starting mechanism is designed to enable the handrail to be directly connected to the top of the column instead of the traditional upper connection method, improving the connection stability and aesthetics. At the end of the handrail, an ending mechanism is set, which is built-in with a preset large-angle arc bend. During on-site installation, only simple comparison and cutting of the redundant part are required, greatly increasing the construction area and reducing the installation difficulty. Advantageous Effects

[0006] 1. Simplify the installation process: Through the innovative design of the unified turning mechanism and the starting and ending mechanisms, the installation of the staircase handrail becomes simpler and faster, and even non-professionals can easily complete it.

[0007] 2. Reduce production and material costs: The design of the new turning mechanism simplifies the complexity of processing staircase turns in the factory, reducing unnecessary material waste and production costs.

[0008] 3. Improve aesthetics: The novel design not only simplifies the installation process, but also improves the overall aesthetics of the connection between the staircase handrail and the column, making the staircase a highlight of home decoration.

[0009] 4. Reduce logistics transportation risks: The unified design of the turning mechanism reduces the number of special-shaped parts, lowers the risk of collision during logistics transportation, and reduces transportation costs and after-sales problems.

[0010] 5. Reduce after-sales costs: Due to design optimization and simplified installation procedures, after-sales problems caused by improper installation or material damage are reduced, and after-sales costs and time costs are lowered.

[0011] In summary, the present utility model provides an efficient, economical, and aesthetically pleasing connection treatment method for solid wood handrails, columns, and elbows of stairs, which has significant technological progress and practical application value.
