HRP20161185A2 - Reusable wooden joint for connecting elements of wooden products made from plywood - Google Patents

Abstract

Reusable clip for product surfaces made of plywood is a detachable, secure joint between the two surfaces. It is distributed on bonded surfaces without the use of adhesives or other materials. The buckle is made of the same material and is an integral part of the surfaces that are joined. No tools are required to assemble and disassemble the buckle. The elastic part of the pen with the extender (1) and the pen without the extender (2), are located on one surface and the opening for receiving the feather (4) on the other. The elastic and mechanical properties of the buckle are determined by the material used.

Description

Areas to which the invention relates Industry:

Joining technique

Clip for multiple connection of product elements made of plywood intended for multiple connection and disassembly of product elements.

The applicant is not aware of the international classification (IC) for this product.

Technical problem

With products made of plywood (for example, packaging, toys, etc.), which are used in industry, household, and service activities, the problem of one-time and repeated disintegration of the product during storage or transportation is especially pronounced. The application of clips for multiple connection and disassembly of product elements enables: disassembly of the product, completeness of design ideas, use of one material for the production of the entire product, improvement of environmental and occupational safety conditions, and the application does not create additional waste in the assembly or disassembly process. By using a clip on products, which in previous practice were not disassembled or were not disassembled more than once (such as boxes, cassettes), the required space during storage and/or transportation is reduced. The use of a clip for repeatedly connecting elements of product parts speeds up the production process, saves space and costs in the entire process of using the product and the service or function for which it is intended. The use of a clip for repeatedly connecting elements of product parts solves the problem of connecting product elements without the use of binding material (glue) or additional connecting materials (nails, sheets, etc.) or the use of tools.

State of the art

Research on the state of the art was done online, and the names and expressions (in Croatian and English) were used as the basis for the review/comparison:

CLIP FOR MULTIPLE CONNECTION AND DISASSEMBLY, WOODEN CLIP, WOODEN JOINT, DOW TAIL JOINT, JOINT

OF WOODEN PANELS, WOODEN DOCK, WOODEN FUSE, WOODEN FUSE

and

WOODEN JOINT, WOODEN CLIP, JOINING WOODEN PARTS, WOODEN PIN, WOODEN SAFETY PIN, WOODEN PEGS, TREENAIL

The above expressions are indications of technical solutions for connecting elements of a decomposable product made of wood, metal, plastic, where the forms of connecting elements are used using glue, metal parts connected with nails, screws, which makes the product non-decomposable or difficult to decompose with a high risk of joint damage.

A search on the Internet according to the names of the compounds mentioned above did not give a result that is comparable to the proposed solution. Most of the results of the joints found differ from the patent proposal, since they are made using profiled grooves without elastic forces by inserting into each other (eg "dovetail"), where the stability and strength of the joint is particularly affected by the quality of the material used, which causes difficult disassembly.

Presentation of the essence of the invention

The primary objective of the invention of clips for multiple joining of elements is to provide a stable, safe and detachable connection between the elements of the structure/product made of plywood.

The secondary goal of the invention is to ensure the creation of a product element using a unique technology without additional operations, checks and tools in the manufacturing process.

Additional objectives of the invention of the clip for multiple joining of elements is to enable easy manipulation without requiring additional training of workers/persons and easy recycling of products with the aim of protecting the environment.

The use of a clip for multiple connection of elements facilitates the design of foldable products made of plywood. The physical properties and dimensions of the welded parts of the wooden clip for multiple joining of elements enable adaptation to the properties of the used type and/or wood performance without losing the properties of the joint.

Method of application of the invention

The invention is intended for vertical multiple connection and disassembly of elements of detachable surfaces (sides) made of plywood using a clip for multiple connection of elements, which is an integral part of the surfaces that are connected. Connecting and disconnecting is done by pressing the clip without using additional tools. The production of the buckle is part of the same technological process that is used to produce the surfaces. Applying this method of joining the surfaces of wooden constructions made of plywood enables a cheaper and faster process of joining and disassembling demountable products and large and economically justified savings in storage, storage and transport. With the correct choice of wood (plywood), long-lasting solutions for demountable plywood products and great flexibility in complete design solutions of products are achieved. The invention enables the manufacturer and the owner to save recycling and save the environment, especially if eco-plywood is used.

A detailed description of at least one way of realizing the invention

Details of this presumed embodiment of the invention are illustrated in the accompanying drawings.

Referring to Figures 1, 2 and 3, it can be seen that the wooden clip consists of a tongue with a protrusion 1 and a tongue without a protrusion 2, which are located on a flat surface A (Figure 1) and an opening for receiving the tongue 4 located on flat surface B (figure 2). The buckle is closed by inserting feathers 1 and 2 into the hole for receiving feathers 4. The surfaces are connected (picture 3) to each other at an angle of 90°.

Dimension 5 corresponds to the thickness of the used material of surface B, on which the opening for the pen 4 is made.

The purpose of the slots 3 is that the tongues with protrusion 1 and the tongues without protrusion 2 can be compressed to a size that allows the tongues and 2 to enter the opening 4. In the opening 4, after releasing the grip on the tongues 1 and 2, the opening is completely closed due to the elasticity of the material used, and the protrusions on the feathers 1 cross the edge of the opening 4, closing the connection.

The depth and width of the groove 3 are determined and adjusted during production according to the strength and elasticity of the wood used (plywood).

List of positive tags used

1 - feather with a point

2 - nib without tip

3 - slots for ensuring the bendability of the buckle parts

4 - opening for receiving a pen

5 - indication for the depth of the notch in the element A A - surface of the pen holder

B - surface holder of the hole for receiving the pen
