Description of the Related Art Conventionally, in order to change clothesline, in addition to a fixed type in which a rod support is provided at a step, a gate type electric lifting device having columns on the left and right (Japanese Patent Laid-Open No. 2000-102697) (See Japanese Patent Laid-Open No. 2001-259297), and
Mainly powered by electricity, such as a ceiling storage box type electric lifting device (see Japanese Patent Laid-Open No. 10-211396), which is relatively complicated, large in size, lacks in layout, and is expensive.

[0003]

As described above, especially in the veranda, the fixed type which is an obstacle or dangerous to a high place is out of the scope, but the electric control system is almost the same because it is of a power-driven type. It was attached, and the space of the veranda was narrowed due to the mechanism, it could not be installed on the veranda ceiling, and it could not be laid out freely, anyway simplicity, compactness, layoutability,
In addition, there were various problems in terms of cost that the product was not commercially available.

The present invention is safe and comfortable for humans, and for dry clothes by systematizing various elements such as unique functions and features of each element and a rod, wire rope, pulley, and compact and highly functional elevator controller. The original basic purpose of the clothesline lifting device, which is sunny and well-ventilated, can be achieved, and most people (including general elderly people and people with physical disabilities) can easily and easily operate and use the handlebars. In addition, the purpose is to provide an effective space such as a veranda, which is simple and compact, and has excellent layout, practicality, and cost-effectiveness.

[0005]

In order to achieve the above-mentioned object, the present invention avoids the demerit associated with the use of household electric power, and at the same time moves the clothesline up and down by which a heavy load is manually and comfortably hung. In order to be able to freely control the arbitrary stop, including the lifting controller with a handle, swinging pulley unit, compound pulley unit, single pulley unit,
This was achieved by the unique or unique functions of the wire rope and rod elements and their system functions.

By using the above-mentioned wire rope which is durable and extremely resistant to rust and connecting each element organically and simply, it contributes to the simplicity of the entire system.

Further, the single pulley unit / composite pulley unit that suspends the clothesline is compact and is attached to the ceiling (mainly the balcony ceiling). Of course, when the clothesline is not hung up at the top, Even when clothes are dried, the effective space of the balcony can be used almost as designed. And since the dried clothes are located at a high place, the sunlight and the ventilation are improved, so that the efficiency of the clothes drying is significantly increased.

Further, by using the swing pulley unit, the single pulley unit and the composite pulley unit together, the mounting angle can be freely set, so that two rods are arranged in parallel (Fig. 2) and in series (Fig. 8). It can be laid out and the mounting position of the lift controller (Fig. 2) can be mounted in a place convenient for the user.

By rotating a handle connected to a shaft that can be switched and interlocked with two sets of wire winding pulleys in the lifting controller, the clothesline can be lifted and lowered in a balanced manner, and at the same time, a torsion coil spring in the lifting controller, etc. It has a lock function by and can stop at the desired position instantly by stopping the turning of the handle.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described. FIG. 1 shows the basic system of the present invention. (A) Mainly consists of clothesline, wire rope, single pulley unit, compound pulley unit, swing pulley unit and compact and high-performance elevator controller. Wire rope 5A connected to both ends of clothesline 1A with fasteners is passed through single sheave unit 2A and compound sheave unit 3A fixed to the ceiling with anchor bolts, and also through 2 sheaves 1 set swing sheave unit 4 and then the lower part. Connect to the wire rope 6A of the lift controller 7 mounted on the wall. on the other hand,
The other set of clothesline 1B, wire rope 5B, single pulley 2B and compound pulley 3B are connected as described above, and the elevator controller is attached to the lower wall after passing through 4B of 2 vehicles 1 set swing pulley unit 4 Connect with 7 wire rope 6B. (B)
The lifting controller can rotate the handle that is connected to the shaft that can be switched and interlocked with the two sets of wire pulleys that have built-in wires. ,
It is possible to control the stop position of the rod.

In the embodiment shown in FIG. 2, the two rods can be laid out in parallel as in the basic system shown in FIG. 1, and the lifting controller is mounted at the imaginary position. In addition, the mounting position of the elevator controller can be set to the right side of the window by reversing the mounting positions of the composite pulley unit and the single pulley unit.

In the embodiment shown in FIG. 8, when the width of the veranda is wide, two rods can be laid out in series, but the mounting position of the lifting controller is to be mounted between the rods. At this time, the left and right combined pulley units are attached to the swinging pulley unit side, respectively, and the attachment position of the single pulley unit is reversed.

In the embodiment shown in FIG. 3, the mechanism of the lift controller is shown. In the embodiment shown in FIG.
As you can see the internal mechanism of the lift controller, the spring case, core, wire pulley,
There are two sets consisting of torsion coil springs and wire ropes, there is a shaft with a cross-shaped cam, and a handle is attached to the tip of the shaft (handle of handle can be built in). In the case of the position shown in the drawing, when this handle is turned, the coaxial cam (see FIGS. 3 and 4) fixed to the shaft meshes with the core cam inside the core (see FIG. 4), so The child turns. At the same time, the wire pulley claw integrated with the wire pulley at the cut end of the core (see Fig. 4)
Is caught, and the drive is transmitted such that the wire pulley also rotates. At this time, the other set of core cams (B side) will come off and will not rotate. Conversely, when the shaft is pulled, the cam on the A side core is disengaged this time, and the cam on the B side core engages with B.
Drive is transmitted through the wire pulley on the side.

In the embodiment shown in FIG. 5, first, a torsion coil spring is mounted inside a spring case fixed to the main body. Both ends of the spring are bent so that the cut end of the core and the wire pulley claw are caught. The positional relationship between the core, the wire pulley claw, and the torsion coil spring is as shown in the arrow view from T to T in FIG. When trying to rotate the core (that is, when raising and lowering the clothesline), the torsion coil spring is rotated so as to be narrowed, so that the diameter of the spring is reduced, and a gap is created between the spring case and the spring. It rotates smoothly, so the core, coil spring, and wire pulley are pushed by the core and rotate at the same time (state in Fig. 6). However, when the wire pulley claw tries to rotate by itself (that is, when the force of lowering the weight of the laundry acts), it pushes both ends of the torsion coil spring, so that the diameter of the coil spring tries to bulge outwards and the spring case is opened. Pressing pressure works and suppresses rotation and locks (state of FIG. 7).

[0015]

Since the present invention is constructed as described above, it has the following effects.

Since the lifting controller has the functions of free lifting and automatic locking, most people (including general elderly people and persons with disabilities) can easily, easily and safely control the height position of the clothesline. be able to.

Since it is dedicated to manual operation, compactness of the apparatus can be realized. In addition, any demerit (leakage
Power failure, failure of electric circuit, electricity cost, and high initial cost can be avoided, and it is safer and can be used for a long time.

Due to the functionality of the overall system and the compactness of each pulley unit, when the clothesline is raised to the top, it can be very close to the ceiling and does not get in the way of people, greatly increasing the effective space of the balcony. .

Further, by using the swing pulley unit, the single pulley unit and the composite pulley unit together, the mounting angle can be freely set, so that the two rods are arranged in parallel (FIG. 2) or in series (FIG. 8). ) And the mounting position of the lift controller (Fig. 2) can be mounted in a place that is convenient for the user. Therefore, even one balcony has 2
Even if connected, we can provide the best layout of this system according to the user's request.
