2 and 3, the present invention provides a ceiling fixing frame 60 that can be fixed to the ceiling of the apartment veranda.

The ceiling fixing frame 20 is formed in a similar rectangular shape as in the longitudinal direction of the veranda.

In addition, the sprocket 30 is positioned at the center of the ceiling fixing frame 20 to be rotated.

The motor for rotating the sprocket 30 is characterized in that it automatically stops when an impact is applied during rotation for DC.

In addition, the DC motor 33 is rotated again by reactivating what has been stopped using an operation switch (not shown). Such a motor is widely distributed in the market.

In addition, when the DC motor 33 of the present invention is stopped by a worm gear type motor, it has a function of not being rotated in any direction but being kept in a stopped state.

Guide guides 55 are formed on both sides of the sprocket 30 formed as described above so that the ball chains 40a and 40b are engaged with each other.

The ball chains (40a, 40b), a plurality of balls 46 are made in sequence by the connecting pin 42.

Up and down fixed stoppers 52a and 52b capable of raising and lowering ball chains 40a and 40b that are passed through and moved are formed at both ends of the guide guide 55.

Further, on the ball chains 40a and 40b which are moved by the sprocket 30, the up and down fixed stoppers 52a and 52b are rim supported so that the up and down movement stoppers which can set the height of the laundry dryer ( 50a) and 50b are formed.

4 and 5, the up and down movement stoppers 50a and 50b formed in the ball chains 40a and 40b rotated by the sprocket 30 are ball chains 40a. ), 40b is formed so as to be wrapped in the outer diameter side that is connected in the longitudinal direction with a plurality of balls 46 and the connecting pin 42.

In addition, as can be seen in Figure 6, the sprocket (30) rotated by the DC motor 33, the guide fitting groove on the outer diameter side so as to move smoothly while the connecting pin 42 of the ball chain (40a) inserted 32 is formed.

In addition, the release pin 39 is formed so that the connecting pin 42 is inserted into the guide fitting groove 32 of the sprocket 30 is moved more than a predetermined distance in the inserted state.

The operation relationship of the laundry drying machine lifting device using the ball chain of the present invention configured as described above will be described in detail as follows.

2 and 3, the user rotates the DC motor 33 mounted with the sprocket 30 mounted on the ceiling fixing frame 20 of the veranda using an operation switch such as a remote controller. To make it work.

When the sprocket 30 is rotated counterclockwise by the operation of the user, the ball chains 40a and 40b caught in the sprocket 30 are moved to both ends of the ceiling fixing frame 20.

As described above, the ball chains 40a and 40b moved to the outside of the ceiling fixing frame 20 by the rotation of the sprocket 30 are guide rollers 62a and 62b formed at both ends of the ceiling fixing frame 20. Guided to the lower side to be lowered to the lower side of the veranda in a vertically bent state to the lower side of the laundry chain (not shown) hanging on the ends of the ball chain (40a, 40b).

At this time, the ball chain (40a), the ball 46 and the connecting pin 42 of the ball chain (40a, 40b) moved by the sprocket 30 is moved up and down so as to smoothly move in a jammed state without hanging, 52a, It is preferable to pass the guide guide part 55 which has 52b.

The guide guide portion 55 is formed in a straight line so as to move horizontally without being separated outward while ball chains 40a and 40b are caught in the outer circumference of the sprocket 30, and the outer circumference of the sprocket 30 Since the inner diameter side of the guide guide portion 55 is formed to be spaced to a minimum, the ball chains 40a, 40b sequentially connecting the plurality of balls 46 using the connecting pins 42 are not sprocketed without being separated. It is precisely caught and transferred between the gear teeth of 30).

In addition, as shown in Figure 6, the sprocket 30, guide chain groove formed on the outer circumferential side of the sprocket 30, that the ball chain 40a, 40b is smoothly moved without falling out of the sprocket 30 Connecting pins 42 connecting the ball 46 to the 32 is caught and moved more easily.

Therefore, the ball chains 40a and 40b are guided by the guide fitting grooves 32 of the sprocket 30 and are pulled and pushed by the sprocket 30 without being pulled out or turning.

In addition, a connection formed between the ball 46 and the ball 46 of the ball chains 40a and 40b rotated by being engaged by the guide fitting groove 32 of the sprocket 30 by the locking release part 39. Pin 42 is no longer rotated along sprocket 30 and is released. It is formed so that the ball chains 40a and 40b are caught by the catch release part 39 located further inward from the position fitted in the guide fitting groove 32 of the sprocket 30, so that the sprocket 30 The ball chains 40a and 40b are wound and tangled in the direction of rotation.

Since the locking release portion 39 is formed to be located at an inner diameter side than the positions of the ball chains 40a and 40b which are inserted into the guide fitting grooves 32 of the sprocket 30 and rotated, the sprocket 30 rotates. It can be prevented that the connecting pins 42 of the ball chains 40a and 40b are caught in the caught direction.

As shown in FIG. 4, when the ball chains 40a and 40b are conveyed as described above, when the ball chains 40a and 40b are completely lowered by the sprocket 30, the upward movement stoppers formed on the line of the ball chains 40a and 40b. The sprocket 30 is stopped automatically by the 50a caught by the rising fixed stopper 52a.

That is, the DC motor 33 for rotating the sprocket 30 further progresses while the upward movement stopper 50a fixed to the ball chain 40a abuts against the upward fixed stopper 52a of the guide guide portion 55. If not wound to the extent that the load is applied to the DC motor 33 for rotating the sprocket 30 is characterized in that it is automatically stopped.

This is characterized in that the DC motor 33 is blocked from being rotated when the load is applied to the state in which it cannot be continuously rotated in the rotational direction at the time of manufacture. This is to prevent the motor from being burned down when power is continuously supplied to the DC motor 33 under load, and such motors are widely distributed in the market.

Therefore, even if the user keeps pressing the operation switch, the DC motor 33 is no longer rotated by the upward movement stoppers 50a and 50b mounted on the ball chains 40a and 40b. It is automatically stopped because it gives a load.

When the user rotates the DC motor 33 mounted with the sprocket 30 in the clockwise direction using the operation switch, the ball chains 40a and 40b are moved while being raised again.

When the ball chains 40a and 40b are raised to some extent by the sprocket 30, the downward movement stopper 50b mounted on the ball chains 40a and 40b is lowered and fixed stopper 50b of the guide portion 55. The load is applied to the DC motor 33 for rotating the sprocket 30 while being hit by the load.

In this way, since the up and down movement stoppers 50a and 50b are mounted on the ball chains 40a and 40b, the sprocket 30 rotated by the DC motor 33 can be easily controlled without other devices. There is a characteristic.

In addition, the DC motor 33 for rotating the sprocket 30 in the present invention is stopped when a load is applied in the rotation direction, the motor is not rotated in the stopped state without the application of power.

The DC motor 33 is not rotated in a stopped state without another brake device after being stopped, and the laundry weight is hung on the clothes dryer hanging in the stopped state on the ball chains 40a and 40b. DC worm gear motors are available on the market to prevent them from being lowered by the load.

In particular, the up and down movement stoppers 50a and 50b mounted on the ball chains 40a and 40b are generated while hitting the up and down fixed stoppers 50a and 50b of the guide guide 55. Multi-level holes 51a, 51b, 51c inside the up and down movement stoppers 50a, 50b so as to prevent the ball chains 40a, 40b from being broken by the impact. Is forming.

As illustrated in FIG. 5, the holes 51a, 51b, and 51c formed in the above-described multi-steps have the size of the ball 46 of the ball chains 40a and 40b. The same size is made larger so that the outer circumferential surface of the next connected ball 46 is not reached.

In addition, since the holes 51c formed in the up and down movement stoppers 50a and 50b are formed larger than the hole 51b positioned at the center, they are formed before the ball 46 located in the hole 51b. It does not touch the inner diameter side.

As shown in (a) of FIG. 5, when the ball chains 40a and 40b are rotated in the direction of the arrow by the sprocket 30, the upward movement stopper 50a collides with the upward fixed stopper 52a. At the same time, the impact is applied to the ball 46 located in the hole 51a.

When a long-term impact is applied to the ball 46 located in the hole 51a as described above, the connecting pin 42 connecting the same is broken as shown in FIG.

As described above, even if the ball 46 of the ball chains 40a and 40b located in the hole 51a is broken, the ball 46 located in the second hole 51b formed inside the upward movement stopper 50a. Can be prevented from hanging.

Further, even if the ball located in the second hole 51b is broken by the fatigue load due to prolonged use, as shown in Fig. 5C, the ball 46 located in the third hole 51c is shown. The ball chains 40a and 40b can be prevented from breaking because they are connected without exiting from the inner diameter side of the hole 51c.

In addition, since the ball chain of the present invention is flexibly connected between the plurality of balls 46 using the connecting pins 42, no entanglement or the like occurs and one end of the ball chain is raised when one side is raised. Of course, it can be used to form a chain box 41 that can prevent the sagging to the lower side.

The laundry drying rack installed on the veranda of an apartment, etc. by the lifting and lowering device for the laundry drying rack using the ball chain of the present invention configured as described above has an effect of automatically unfolding or folding the housewife as well as the elderly.

In addition, since the rotational force is transmitted by the ball chain method, there is no loss of the transmitted force, and it stops when a load is applied to the motor which rotates the sprocket, and after the stop, it does not rotate without the application of power. Due to the use of a motor, it is possible to spread the product price significantly lower than a conventional automatic laundry drying machine.
