Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to an assembly type futon dryer.

(Prior Art) Some conventional assembling futon dryers use pipes, etc., but all of them are assembled using screws.

Due to its structure, conventional assembling type futon dryers require a screwdriver or the like to tighten screws during assembly, resulting in the problem that assembly is time-consuming. Additionally, problems such as hand injuries and lost screws occurred during assembly.

(Problems to be Solved by the Invention) The present invention was devised in view of the above points, and its object is to eliminate the need for screws and to devise a device that can be easily assembled.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a terminal pipe formed by connecting a plurality of short pipes between the upper and lower ends of two pipes of a predetermined length, and an upper end of the terminal pipe. One end of the upper pipe is fitted to the terminal pipe, one end of the lower pipe is fitted to the lower end of the terminal pipe, and a support pipe is fitted to the other end of the upper pipe and the other end of the lower pipe. At both ends of the terminal pipe and at both ends of the support pipe, the tip of the pipe is squeezed in so that a pipe of the same diameter can be fitted, and a tip part with a reduced diameter is provided, and the fitting range at the tip part is approximately A circumferential groove is provided on the outer peripheral surface of the middle, a groove is provided from the circumferential groove toward the tip of the pipe, and both ends of the upper pipe and both ends of the lower pipe are capable of fitting into the groove and the circumferential groove. This method takes the form of providing a protrusion on the inside of the pipe.

(Function) The protrusion 8 at one end of the upper pipe 7 is inserted into the groove 6 of the tip 4 at the upper end of the terminal pipe 1, and by further rotating the upper pipe 7 around the axis, the protrusion 8 of the upper pipe 7 is inserted into the groove 6 at the tip 4 of the upper pipe 1. Since the upper pipe 7 and the terminal pipe 1 are fitted by sliding in the inner circumferential groove part 5 of the part 4, the upper pipe 7 and the terminal pipe 1 are fitted together.

Also, insert the protrusion 8' at one end of the lower pipe 7' into the groove 6' at the tip of the lower end of the terminal pipe 1,
By rotating the lower pipe 7' around the axis, the protrusion 8' of the lower pipe 7' slides in the circumferential groove 5' of the tip end 4', and the lower pipe 7' and the terminal pipe 1 are fitted together.

Furthermore, the protrusion 8 on the other end of the upper pipe 7 and the protrusion 8' on the other end of the lower pipe 7' are connected to the support pipe 9.
By inserting the support pipe into the groove 12 of the tip 10 at both ends and rotating the support pipe around the axis, the protrusions 8, 8' of the upper pipe 7 and the lower pipe 7' will fit into the tip 10.
The upper pipe 7, the lower pipe 7', and the support pipe 9 are combined to form a set of futon drying frames.

Then, the futon dryer is assembled by sequentially performing the following operations on the remaining tip portions of the terminal pipe 1. Each futon drying frame can be rotated around the terminal pipe 1, and can be put into practical use by closing them all in the same direction or opening them at an appropriate angle (see Fig. 5).

(Example) An example of the present invention will be described based on the drawings. Reference numeral 1 denotes a terminal pipe, which is made up of two long pipes 2 of a predetermined length arranged at an appropriate interval, and three short pipes 3, 3' connected between them. At both the upper and lower ends of the terminal pipe 1, there are provided tip portions 4, 4' whose diameters are reduced by squeezing the tips of the pipes so that pipes of the same diameter can be fitted. Circumferential grooves 5, 5' are provided approximately in the middle of the range, and grooves 6, 6' are provided from the circumferential grooves 5, 5' toward the pipe tip.

The upper pipe 7 is a straight pipe with the front and rear ends bent downward to form a downward flat U-shape, and the lower pipe 7' is a straight pipe with one end bent downward at the front and rear ends to provide a grounding part. After that, it is bent upward to form a predetermined shape, and both ends of the pipe are bent in the vertical direction, and protrusions 8 and 8' that project inside the pipe are provided.

Therefore, one end of the upper pipe 7 is inserted into the tip 4 of the pipe 2 of the terminal pipe 1, the protrusion 8 of the upper pipe 7 is inserted into the groove 6 of the tip 4, and the upper pipe 7 is rotated around the axis, for example, to the right. When turned, protrusion 8
slide in the circumferential groove 5 and fit together, and the upper pipe 7 and the terminal pipe 1 are assembled. Also, connect one end of the lower pipe 7' to the terminal pipe 1.
into the tip 4' of the pipe 2, insert the protrusion 8' of the lower pipe 7' into the groove 6' of the tip 4',
When the lower pipe 7' is rotated around the axis, the protrusion 8' slides and fits into the circumferential groove 5', and the lower pipe 7' and the terminal pipe 1 are assembled.

The other end of the upper pipe 7 and the other end of the lower pipe 7' are connected by a support pipe 9. Projections 8, 8' are also provided at the tips of the upper pipe 7 and the lower pipe 7' to protrude inside the pipes, and the tip 1 of the support pipe 9
An axial groove 12 and a circumferential groove 11 in the circumferential direction are formed on the outer surface of the 0. Insert the strut pipe 9 into the upper pipe 7 and the lower pipe 7', slide the projections 8, 8' from the groove 12 into the circumferential groove 11, and fit the strut pipe 9 and the upper pipe 7.
and the lower pipe 7' are connected.

Other pipes 2, 3, 3' of terminal pipe 1
Similarly, the upper pipe 7, the lower pipe 7', and the support pipe 9 are fitted to the upper pipe 7' and the support pipe 9, respectively, to complete the assembly of the five sets of futon drying frames.

When in use, rotate the upper pipe 7 a little to create an interval between each drying frame, and place the futon 15 on the upper pipe 7.
This means hanging it to dry. The protrusion 8 and groove 6 are designed to prevent the connection between the upper and lower pipes 7 and the support pipe 9 or the terminal pipe 1 from coming off due to rotation during use.
It goes without saying that the positional relationship between the two should be set in advance.

(Effects of the Invention) Since the present invention is constructed and operates as described above, it has the following unique effects.

First, since no screws are required for assembly, there is no need for tools such as a screwdriver. As there is no need to tighten screws, assembly is very easy. Since there is no need to tighten screws, there is no need to worry about hand injuries during assembly. Since no screws are used, the futon dryer is easy to manufacture, does not take up much space for storage, transportation and display, and can be stored compactly when not in use even after purchase and use, making it very convenient.
