Wooden drum structure

The present invention relates to a wooden box drum structure, and more particularly to a wooden box drum structure comprising a first body, a second body and a plurality of third bodies, the first body and the second system being combined into a closed frame, The wooden drum structure of the creation achieves the effects of increasing practicality, diversity and cost saving.

As we have previously known, the wooden box drum structure used in the past is supplemented by the tenth and thirteenth figures. The tenth figure is the exploded view of the wooden drum structure. The eleventh figure is the wooden drum. The three-dimensional combination diagram of the structure, the twelfth figure is a three-dimensional exploded view of the second conventional wooden box drum structure, and the thirteenth figure is a three-dimensional combination diagram of the second conventional wooden box drum structure, the conventional wooden box drum structure, the system The two first panels 51 and 61 are provided with a sounding hole and two second panels 52 and 62 at the center of each of the first panels 51 and 61. A perforation is provided for the user to wear a strap, and four arcuate members 53 are disposed between each of the first panel 51 and each of the second panels 52, that is, the arcuate member The 53 series connects the first panel 51 and the second panel 52, and the two third panels 54, 64 have a quadrangular shape.

However, the lack of this custom wooden box drum structure is:

1. Referring to the tenth and eleventh drawings, the conventional wooden box drum structure includes two first panels 51, two second panels 52, four curved surfaces 53 and two thirds. The panel 54 is composed of a total of ten components, and the wooden drum structure has a large number of components, which greatly increases the cost of the conventional wooden drum structure.

2. Please supplement the twelfth and thirteenth figures. In the industry, there are ten components in order to reduce the structure of the used wooden box drum. The second conventional wooden box drum structure is to have four arc pieces. 53 is omitted, that is, each of the first panels 61 is combined with each of the second panels 62.

However, the absence of this second conventional wooden box drum structure is: In the tenth and eleventh drawings, the four corners of the conventional wooden box drum structure are in the form of an inverted curved surface at the four corners, and the second conventional wooden box drum structure omitting the four curved surface members 53 is four. The corners are in a right angle, and the second conventional wooden drum structure is less aesthetically pleasing, so there is another missing structure.

In view of the lack of the above-mentioned conventional wooden box drum structure, the creator has been engaged in the manufacturing, design and sales experience of related industries for many years, and finally has a product that can solve the drawbacks of the wooden drum structure.

A new type of problem to be solved: the conventional wooden box drum structure has a lack of more components or a lack of appearance in a right angle. The wooden drum structure of the present invention includes a first body, a second body, and a plurality of third bodies. The first body and the second system are combined into a closed frame structure, which enables the creation of the wooden box drum structure to increase the utility, the appearance diversity and the cost saving effect.

The technical means for solving the problem: the present invention relates to a wooden drum structure, comprising: a first body, the first body is provided with a main portion, and each side of the main body is provided with a first connecting portion; The second body has a second connecting portion at each end of the second body, and the second connecting portion is combined with the first connecting portion of the first body, and the first system is combined with the second system. a frame having a closed shape; a plurality of third bodies, the third system being coupled to the two sides of the first body and the second body, the third system and the first body and the second body The shape matches.

Compared with the effect of the prior art: the wooden drum structure of the present invention can be assembled into a wooden box drum structure only by the first body, the second body and the two third bodies, which saves the structure of the wooden drum structure of the present invention. The cost of the effect. The first system and the second body are combined into a frame having a closed cross-section, so that the whole wooden box drum structure can be a quadrilateral of a conventional section, or a hexagonal shape, or a heart shape, of course, the first body and The second body can also be combined into an apple shape, a circle shape, a geometric shape, or other shapes. The first body and the second system are combined into a closed-shaped frame, so that if the system is combined into a quadrilateral as shown in the second figure, the first system can be directly provided with an arc surface.

In order to enable the members of the Board and those skilled in the art to fully understand the effects of this creation, the structure and composition of the creation are described in conjunction with the drawings and drawings, but the following are only used to explain the implementation of this creation.
