Description

Technical Field

[0001] The invention relates to a round bamboo pole fastening system, in particular to a fastening system for fastening a round bamboo pole to other components. Background Art

[0002] At present, round bamboo poles are often used as connectors for furniture. Patent publication number CN204512106U discloses a connector suitable for standardized and detachable design of round bamboo furniture, which is essentially a life extension of the traditional wrapping structure under the contemporary standardized and mechanized production mode. The end of the product is either with an expansion joint and an internal threaded sleeve, or with an external threaded connector; its form is diverse, including a straight-line connector, an L-shaped or T-shaped connector, and a three-dimensional three-way connector, which is suitable for connecting and fastening round bamboo poles to each other. However, since the round bamboo pole connected to the external threaded connector needs to be threaded inside its end, and the round bamboo pole connected to the internal threaded connector with an expansion joint needs to be threaded outside its end, this method requires a relatively high degree of uniformity in the size of the round bamboo pole. Among them, although the internal threaded connector has an expansion joint, the tolerance for the diameter difference of the round bamboo pole is still very limited. Therefore, the labor cost or time cost consumed in the selection of round bamboo poles is relatively high. In addition, when connecting to the tabletop, a set of frame components with a stable structure composed of round bamboo poles and connectors is required, and a large number of connectors are used, which is not very conducive to the preservation of the natural affinity and cultural sense of the appearance of round bamboo furniture. Patent publication number CN202579513U discloses a detachable hardware connector for round bamboo furniture, and the structural parts include a double-headed screw and a pull rod. The two ends of the double-headed screw are respectively connected to the fixing cap by threads, and are fastened to one end of the round bamboo pole. The other end of the pull rod connected to the double-headed nut is connected to the pull rod adjustment piece by threads, and another round bamboo pole is vertically connected and fixed to the end of the round bamboo pole fastened to the double-headed screw. This set of hardware connectors is hidden inside the round bamboo pole and is used for the T-type connection of the round bamboo pole. From the mechanical relationship of the structure, it can also be used for the T-type connection of the round bamboo pole and the board. Patent publication number: CN2882392, discloses a connection device for bamboo furniture, wherein the connection piece vertically passes through several round bamboo poles stacked in a "well" shape, and the two ends are connected to the fasteners through threads, fastening all the round bamboo poles together. The patent is a connection device suitable for making round bamboo furniture.

[0003] From the patents of similar and related products and related papers, we can draw the following conclusions:

[0004] 1. It is the consensus of almost all researchers and designers to use modern mechanized production methods for mass production and to design standardized, modular, and detachable round bamboo furniture.

[0005] 2. There are three types of mechanized mass-produced connectors suitable for round bamboo poles: A, socket connection that can realize the "one"-shaped connection, L-shaped or T-shaped connection, and three-dimensional three-way connection of two round bamboo poles. In the socket connection method, the thickness of the end of the round bamboo pole is reduced, especially the removal of the bamboo green at the end of the round bamboo pole connected to the inner threaded sleeve end has a certain impact on the overall force of the round bamboo pole. Since the mechanical advantages and aesthetic characteristics of the round bamboo pole come from its original ecological materials, due to the requirements of force, the socket connection method will have strict restrictions on the diameter, thickness and curvature of the round bamboo pole. With the trend of increasing labor costs, this method will not be conducive to the control of product costs for the design of round bamboo pole furniture with product requirements. B, internal pull rod connection. The "detachable round bamboo furniture hardware connector" using the pull rod is suitable for the T-shaped connection of two round bamboo poles. The restrictions on the diameter and wall thickness of the round bamboo poles are relatively loose, but it is required that the diameters of the two round bamboo poles have a difference and ensure that the end of one round bamboo pole can be vertically inserted into the other round bamboo pole. Since the straightness and diameter of the original round bamboo poles are not standardized, the stability, firmness and width of the overall morphological structure of the two round bamboo poles connected by the pull rod connection method will be affected by the non-standardized natural shape of the round bamboo poles. C, T-shaped tenons, mortise and tenons or partial injection molding are connected with metal parts. The round bamboo poles after partial injection molding can be connected with more hardware more freely. However, from an environmental protection perspective, whether this method is convenient for material recycling remains to be discussed. In addition, due to the inconsistency of the shrinkage or expansion rate of plastic and bamboo, the round bamboo poles with partial injection molding also have the risk of internal plastic detaching and loosening after long-term use.

[0006] 3. People also expect round bamboo furniture to conform to the contemporary aesthetic trend of simplicity and clarity like furniture made of other materials. However, the existing mechanized and standardized connection components still play a very limited role in the design of round bamboo furniture that conforms to contemporary aesthetic trends and aims at commercialization.
