(Means for Solving the Problems) The specific configuration for solving the problems in the present invention includes at least two vertical main pillars, upper and lower connectors that connect and fix the upper and lower ends of the main pillars, It has at least two clothesline rod frames formed in a substantially U-shape with vertical ends, and each of the connecting devices is vertically divided into two sections, one of which has a main column that is fitted and fixed to the main column. In a clothes drying rack which forms a pillar fitting part on the other hand and a pivot part that pivots the vertical end of the clothes drying rod frame around a vertical axis, each of the connecting devices has a main pillar fitting part and a half of the pivot part. It is formed by removably fixing the main body forming the main body and the lid body forming the other half of the pivot part, and the vertical end of the clothes-drying rod frame and the opposing mating surfaces of the main body and the lid body. A fitting recess that can be split into two is formed in the locking ring provided at substantially the most end thereof, and is fitted from a direction perpendicular to the vertical end to prevent movement in the vertical direction.

(Function) The main pillar fitting portions of the main body of the connector are fitted and fixed to the upper and lower ends of the two vertical main pillars. The two-part fitting recess formed on the mating surface of each main body is fitted to the vertical end of the clothesline rod frame from a direction perpendicular thereto, and the lid body also has a two-part fitting recess. is fitted to the vertical end, and the main body and lid are aligned and fixed.

As a result, the clothesline rod frame is connected to the connecting tool without expanding or contracting, and can rotate freely around the vertical axis at the vertical end, and the locking ring and fitting recess provided at almost the extreme end of the vertical end The vertical engagement is prevented from coming off in the vertical direction.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

Figures 5 to 7 are schematic diagrams of the entire assembly of a three-hook clothes drying rack, where 1 is the main pillar, 2 is the clothes drying rod, 3 is the support,
4 is a connecting rod, 5 is an upper connecting tool of the clothesline rod, 6 is a lower connecting tool of the connecting rod, 7 is a connecting device of the column of the clothesline rod, and 8 is a connecting device between the column and the connecting rod.

The main pillar 1, the clothesline 2, the support 3, and the connecting rod 4 are metal pipes whose outer surfaces are coated with a synthetic resin material. The pillar 3 and the connecting rod 4 constitute a U-shaped clothesline frame, and both ends of the clothesline frame are concentrically opposed vertical ends.

The clothesline rod 2 has one end bent at a right angle to form a downward pivot portion (vertical end) 2A, and the other end 2B bent at an acute angle to face obliquely inward and downward. A synthetic resin connector 7 is fixed with an adhesive.

The upper end portion 3A of the column 3 is bent obliquely outward, and the upper end is removably inserted into the lower part of the connector 7, and the lower end of the column 3 is inserted into the approximately T-shaped synthetic resin connector 8. and adhesive (or screws, etc.)
It is fixed by. Therefore, rainwater does not enter.

The connecting rod 4 has one end bent upward to form a pivot portion (vertical end portion) 4B, and a synthetic resin locking ring 9 is fixed to the upper end (approximately the extreme end) with adhesive. The other end 4A is inserted into a horizontal hole of the connector 8 and fixed with a screw (not shown) or the like.

A locking ring 10 made of synthetic resin is fixed to the lower end (substantially the extreme end) of the pivot portion 2A of the clothesline rod 2 with adhesive. This locking ring 10 is
Since it is the same as the locking ring 9 of the connecting rod 4, and the connectors 5 and 6 have the same structure, and are fixed to the upper and lower ends of the main column 1 in opposite directions, the structure of the connector 5 is as follows. A detailed explanation of the connector 6 will be omitted.

As shown in FIGS. 1 to 4, the connector is vertically divided into two sections, one of which has a main column 1.
A main pillar fitting part is formed on the other side to be fitted and fixed, and a pivot part that pivots the vertical end of the clothesline rod frame around the vertical axis is formed, and the main pillar fitting part and half of the pivot part are formed. is formed on the main body 5A, and the other half of the pivot portion is formed on the lid 5B.

That is, the upper connector 5 has a two-piece structure made of synthetic resin, consisting of a main body 5A and a lid 5B, and has a main pillar insertion hole 11 having a center line in the same vertical plane on the left and right sides of the lower side of the main body 5A. A main pillar connecting protrusion 12 is provided,
As a result, a main column fitting part is formed, and fitting recesses 13A and 13B for the clothesline rod 2 are formed in three places parallel to the axis on the mating surface α where the main body 5A and the lid body 5B face each other. Thus, a pivot is formed, and the center lines of both outer fitting recesses are on the same line as the center line of the main post insertion hole 11.

Recesses 13A and 13B formed in the main body 5A and the lid 5B of the connector 5 each have a semi-cylindrical shape,
The two face each other to form a cylindrical hole that is slightly larger than the outer diameter of the pipe-like clothesline 2 and allows rotation. The main body 5A and the lid 5B are divided into two parts along a plane including the center line of the cylindrical hole. This recess 13
At the lower ends of A and 13B, locking recesses 14A and 14B are provided in which the locking ring 10 is similarly fitted and prevented from coming out in the vertical direction.

The fitting recesses 13A, 13B and the locking recess 14
A and 14B form a fitting recess that supports the pivot portion 2A of the clothesline rod 2, which has the locking ring 10 at approximately the extreme end, in a rotatable and immovable state in the vertical direction, and also allows it to be split into two. The fitting direction with respect to the pivot portion 2A is a direction perpendicular to the pivot portion 2A.

The main body 5A and the lid 5B are each provided with two bolt holes 15 for connecting them, and are removably fixed with bolts 16 and nuts 17.

The main pillar insertion hole 11 provided in the connector main body 5A is a bottomed hole with one side (upper side) closed, so rainwater does not enter the connector, and the lower end of the main pillar 1 is inserted into the connector. 6 is also bonded with adhesive, so there is no fear that rainwater will accumulate inside the main pillar 1.

Furthermore, the ends of the locking rings 9, 10 of the clothesline 2 and the connecting rod 4 are coated with adhesive to prevent corrosion.

According to the embodiment of the present invention, the main pillar 1, the clothesline 2, the support 3 and the connecting rod 4 are connected to the connecting members 5, 6, 7,
It can be disassembled and assembled freely through the clothesline rod 2.
Although the pole 3 is simply inserted, since it is connected by the connector 7 on the slope, it will not easily come out even if the clothesline pole 2 is lifted. In addition, since the main column 1 has connectors 5 and 6 fixed to its upper and lower ends, the clothesline rod 2 and the connecting rod 4 are connected to the fitting recess 13A and the locking recess 14A of the connector main body 5A. Clothes drying rod 2 including locking rings 9 and 10
After fitting the ends of the lid body 5B, the lid body 5B is fitted onto the locking rings 9, 10, etc., the body 5A and the lid body 5B are brought into contact with each other at the mating surface α, and the connector body 5A is secured with the bolt/nut 17. This can be done with a simple operation of just connecting the lid body 5B. When the clothesline rod 2 and the connecting rod 4 connected in this way are rotated, the ends including the locking rings 9 and 10 within the connecting members 5 and 6 rotate smoothly with respect to the main column 1, Each clothesline 2 can be opened at any angle. Even if the clothesline rod 2 is lifted upward to change the installation position, the locking ring 10 of the clothesline rod 2 is locked in the locking recesses 14A and 14B, so the clothesline rod 2 will not slip out upwards and will not move downwards. There is no need to move.

When removing the clothesline rod 2 from the connector 5, it can be easily separated by removing the bolts 16 and nuts 17 and separating the lid 5B from the main body 5A.

The case where there are 3 clothesline frames is shown, but 4, 5
When increasing the number of books, just increase the number of clothesline rod frame fitting recesses between both ends of the connectors 5 and 6 according to the number.
On the other hand, when using two rods, the present embodiment may be used as is, but it is sufficient to manufacture one without the recessed portion for fitting the clothesline rod frame in the middle as shown in FIGS. 1 and 3.

(Effect of the invention) According to the invention described in detail above, the connecting device is a fitting that fits into the vertical end of the clothesline rod frame and the locking ring provided at the substantially extreme end thereof, making it impossible to move in the vertical direction. Since a mating recess is formed, even if the clothesline frame is lifted, the vertical end will not come off from the connector, and the approximately U-shaped clothesline frame will not expand or contract, allowing it to pivot easily. The support connection can be ensured, and even with a retaining structure having a locking ring at the vertical end, the connector has half a pivot portion formed by the main body and the lid. Since the fitting recess can be divided into two, the main body and the lid can be fitted and removed from the direction perpendicular to the vertical end having the locking ring, unlike the conventional technology.
There is no need to expand or contract the clothesline frame to attach or detach it to the connector, and the clothesline frame or the like can be made more durable and robust.
