[0002]

2. Description of the Related Art By operating an operation member formed of a rigid string or the like, a drum body is rotated to draw out or wind up a long body such as a hanging curtain. As the device, a constant restoring force spring unit with a damper as disclosed in Japanese Patent Application Laid-Open No. 3-15092 has already been known. The configuration of this constant restoring force spring unit with a damper will be described below based on the above publication.

The constant restoring force spring unit 1 with a damper has first and second winding drums 3 and 5 rotatably supported by two parallel rotating shafts 4 and 6, respectively, and one end of the first and second winding drums 3 and 5. And the other end is wound on the second winding drum 5 having a diameter larger than that of the first winding drum 3 in a direction opposite to the first winding drum 3. A constant restoring force spring 2 fixed so as to be wound, and supported coaxially with the second winding drum 5, and provided so as to be able to rotate forward and reverse in conjunction with the second winding drum 5; And the second winding drum, which is wound around the wire winding drum 7 in a normal state, and is pulled out, thereby pulling out the constant restoring force spring 2 against the restoring force of the constant restoring force spring 2. 5 and a wire 9 for winding the wire.

According to the above configuration, when the wire 9 is pulled, the wire winding drum 7 and the second winding drum 5 rotate, so that the wire wound around the first winding drum 3 is fixed. As the restoring force spring 2 is pulled out, the restoring force spring 2 is warped and wound on the second winding drum 5. Here, when a certain load is applied to the wire 9 drawn out to an appropriate length,
The wire 9 is pulled out. Then, when this load is released, the constant restoring force spring 2 rewinds to the first winding drum 3 by its own returning force, and accordingly, the wire 9 is also wound around the wire winding drum 7. Thus, the long body can be pulled out or wound by fitting the shaft around which the long body is wound into the wire winding drum 7.

Further, the applicant of the present application has disclosed that a long body can be pulled out and wound up by directly operating a long body such as a curtain so that the drum body can be rotated to draw out or wind up the long body. As a device, a window curtain device as disclosed in Japanese Utility Model Laid-Open No. 7-7581 has been developed. The window curtain device will be described below based on the above publication.

In this window curtain device, a spring mechanism 6 having a main drum 13 around which a leaf spring 16 is wound and a sub-drum 15 which pulls out the leaf spring 16 and winds it back is fixed to the window. A roll curtain 4 having a load balanced with the spring force of the spring mechanism 6 is arranged so as to move up and down in the vertical direction of the window.
Is connected to the slave drum 15 of the spring mechanism 6.

Thus, when the roll curtain 4 wound around is pulled out by hand, the slave drum 15 of the spring mechanism 6 rotates with the rotation of the winding core 5, and the leaf spring 16 is forcibly applied to the slave drum 15. The main drum 13 is wound on the leaf spring 16.
A restoring force for rewinding occurs. For this reason, if the roll curtain 4 having a load that balances the restoring force is released at an arbitrary drawn position, the load of the roll curtain 4 and the spring force of the spring mechanism 6 are exactly balanced, and the roll curtain 4 is unloaded. Can be held. Then, if the roll curtain 4 is lightly lifted from below, the roll curtain 4
The balance between the load and the spring force of the spring mechanism 6 is lost, and the roll curtain 4 is wound around the core 5 by the restoring force of the leaf spring 16.

[0008]

However, in a structure such as the window curtain device disclosed in Japanese Utility Model Laid-Open Publication No. 7-7581, a part of the elongated body is removed or a suspended object is removed. When the is detached, the restoring force of the leaf spring is superior, and even if it is desired to hold the elongated body at that position, the elongated body is arbitrarily unwound.

Further, the above-mentioned Japanese Patent Application Laid-Open No. H3-115092 has been disclosed.
In the constant restoring force spring unit with a damper as disclosed in Japanese Unexamined Patent Publication, especially when the wire is formed of a rigid material, when the wire rewinds to the wire winding drum,
There is a problem that the wire is not wound up neatly on the wire winding drum, protrudes from the groove of the wire winding drum, or the wires are entangled.

Further, in a window curtain device as disclosed in Japanese Utility Model Application Laid-Open No. 7-7581, when the curtain is wound around a core, the curtain expands in the radial direction of the core, so that the curtain is superimposed neatly. However, there is a possibility that a gap is formed between the rolled curtain and the rolled curtain. This problem is remarkable when the long body is formed of a hard material such as an image screen.

Therefore, the present invention is directed to a case where the load of the extended portion of the elongated body and the restoring force of the leaf spring are not balanced, or when the load of the suspended object and the restoring force of the leaf spring are not balanced. However, it is an object of the present invention to provide a long body pulling and winding device capable of stopping the vertical movement of an object halfway.

Further, the present invention provides a structure in which a long member is pulled out or wound by operating an operation member.

FIG. 2 shows a state in which the elongate body pulling and winding device 1 is fixed to an upright wall or the like and a shaft 18 around which the elongate body 17 is wound is assembled. (However, the stopper device 12 is omitted). An example of a method for assembling the elongate body take-up winding device 1 will be briefly described with reference to FIG. 2. This is performed by fitting the shaft body 18 around which the elongated body 17 is wound into the third fitting hole 19.

Based on the above configuration, the function of the elongate body pulling and winding apparatus 1 which is fixed to an upright wall or the like and to which the shaft 18 is attached will be described.

When the operating member 6 is pulled, the drum body 3 and the shaft body 18 fitted into the drum body 3 are rotated to elongate the long body 17 and the constant load spring 9 is wound around the drum body 3. As a result, a restoring force is generated in the constant load spring 9 to rewind the drum body 7. Stopper device 1

Is locked on the inner wall. Accordingly, the rotation of the drum body 3 and the shaft body 18 is stopped, so that the elongated body 17 can be held at the extended position.

Further, when the operating member 6 is pulled again to be loosened, the rod 16 moves from the groove 13g to the groove 13d to release the lock of the drum body 3, and the groove 16 is not caught by the step. 13d, groove 13
Since the drum body 3 and the shaft body 18 move in the order of a and the groove 13e, the drum body 3 and the shaft body 18 are rotated in reverse by the restoring force of the constant load spring 9. Thereby, the operation member 6 is wound around the drum body 3 and the long body 17 is also wound around the shaft body 18.

According to the present embodiment, however, the operation member 6 is pulled out and then loosened, whereby the drum 3
Is stopped by the stopper device 12, the elongated body 17 can be stopped at an arbitrary position.

Although the operation member 6 is wound around the drum body 3 to operate the long body 17, it is not necessarily limited to this. For example, as shown in FIG. 3 (however, the stopper device 12 is omitted), a structure in which the operation member 6 is wound around the circumferential groove portion 5 of the drum body 3 is omitted, and the elongated body 17 is directly operated. Drum body 3
, The elongated body 17 may be inserted through the hole 10 of the plate-shaped member 2a and the bent hole of the braking member 11 '. According to this configuration, since the structure of the long body unwinding and winding device 1 can be simplified, the cost can be reduced, the long body 17 can be stopped at an arbitrary position, and the long body 17 When rewinding to the shaft body 18, it can be neatly wound up.

The long body pulling and winding device 1 shown in FIG.
As in the case of the elongate body unwinding and winding apparatus 1 shown in FIG. 1, a fixed member 2 composed of plate-shaped members 2a and 2b, and a fixed shaft 4 supported by the plate-shaped member 2a of the fixed member 4, 8 and drum bodies 3 and 7 supported by fixed shafts 4 and 8. Then, the winding direction of the drum body 3 and the winding direction of the drum body 7 are reversed so that the constant load spring 9 is wound around the drum body 7 while the constant load spring 9 pulled out from the drum body 3 is warped. Are wound around the drum bodies 3 and 7, respectively. Further, a through hole 10 through which the operation member 6 passes is formed in the plate-shaped member 2b. The structures of the drum bodies 3 and 7, the structure of the fixing member 2, and the structure of the operation member 6 are the same as those described above.

In order to temporarily stop the rotation of the drum 3, a stopper device 20 is provided on the side of the drum 3 opposite to the plate-like member 2a. As shown in FIG. 5, the stopper device 20 includes a substantially fan-shaped locking claw 21 supported on the fixed shaft 4, a heart cam 22 formed on a side surface of the fixed shaft 4, and a locking claw at one end. 21 is locked at a predetermined position, and the other end is a groove 23 of the heart cam 22.
, A return spring 25 that pushes up the locking claw 21 from the center side to the outer peripheral side, and a pressing spring 26 that prevents the rod 24 from coming out of the groove 23 of the heart cam 22.
And a plurality of locking pieces 27 provided on the side surface of the drum body 3.

In the illustrated embodiment, the return spring 25 has a configuration in which both ends of the constant load spring are fixed and the central portion bulges toward the locking claw 21 side. Further, the locking claw 21 has a sharp tip portion at the locking piece 2.
7 is located at a position where the operating member 6
In the wound state, as shown in FIG. 5 (a), the distal end is at a position where it comes into contact with the locking piece 27, and it comes into light contact with the return spring 25. The pressing spring 26 is formed by covering a part of the rod 24 and fixing both ends thereof.

The groove 23 of the heart cam 22 is
As shown in (a) to (e), it is composed of five grooves 23a to 23d. Of these, the groove 23a has a gentle curve, and gradually becomes shallower toward the groove 23b. The groove 23b is composed of a steeply curved portion and a straight portion.
At the boundary with 3a, a step is formed deeper than the groove 23a. The groove 23c has a sharp curve by forming a depression in the inner wall, and is deeper than the groove 23b at the boundary with the groove 23b. The groove portion 23d is composed of a portion forming a gentle curve and a straight line portion protruding from the curved portion, and is deeper than the groove portion 23c at the boundary with the groove portion 23c. Further, the groove 2d is formed such that the groove 23d is shallower than the groove 23a at the boundary with the groove 23a to form a step.
It gradually becomes shallower from the 3c side toward the groove 23a side.

The plate-like member 2b of the fixing member 2
As shown in FIG. 4 (b), a braking member 28 extending from the bottom 3 closes a part of the recess 5 of the drum body 3. Thus, even when the rigid operation member 6 is used, the operation member 6 can be wound around the drum body 3 without being spread in the radial direction of the drum body 3 and coming off the drum body 3.

The state in which the elongate body pulling and winding device 1 is fixed to an upright wall or the like is the same as that of the first embodiment shown in FIG. Further, the drum body 3 does not have a fitting hole, but instead has a plurality of locking pieces 27 protruding from the side surface. Therefore, for example, a fitting hole is formed at the end side of the shaft body 18 so that the locking piece 27 is formed. The fitting of the shaft body 18 is performed by fitting into the fitting hole.

Based on the above configuration, the function of the long body pulling and winding apparatus 1 fixed to an upright wall or the like and having the shaft 18 attached thereto will be described.

When the operating member 6 is pulled, the drum body 3 and the shaft body 18 fitted in the drum body 3 are rotated to elongate the elongated body 17, and the constant load spring 9 is wound around the drum body 3. As a result, a restoring force is generated in the constant load spring 9 to rewind the drum body 7. Further, since the locking piece 27 rotates and comes into contact with the distal end of the locking claw 21 in the state of FIG. 5A, the locking claw 21 resists the restoring force of the return spring 25 and the drum body 3 5 (b) together with
The rod 24 moves from the groove 23a to the groove 23b. While the operation member 6 is continuously pulled, the rod 24 reciprocates in the linear portion of the groove 23b.
1 maintains a state inclined in the rotation direction. This allows
While the operation member 6 is being pulled, the drum 3 and the shaft 18
Keeps rotating, so that the elongated body 17 can be smoothly fed out.

Next, once the pulling force of the operating member 6 is loosened, the drum body 3 rotates in the direction opposite to the direction of the arrow in FIG. Passes through the locking claw 21 and the locking claw 21 rotates in reverse with the drum body 3 by the restoring force of the return spring 25, so that the rod 24 has the groove portion as shown in FIG. After moving from 23b to groove 23c, it is locked to the inner wall of groove 23c. As a result, since the locking claw 21 is fixed, the locking piece 27 is locked by the locking claw 21 and the rotation of the drum body 3 and the shaft body 18 is stopped. Can be held in position.

Further, when the operating member 6 is pulled, FIG.
As shown in (d), the drum body 3 rotates in the direction of the arrow in FIG. 5 (d), thereby generating a restoring force in the constant load spring 9 to rewind the drum body 7, and the drum body 3 The locking piece 27 that rotates together with 3 comes into contact with the distal end of the locking claw 21 in the state shown in FIG. For this reason, the locking claw 2
5 rotates integrally with the drum body 3 in the direction of the arrow in FIG. 5D against the restoring force of the return spring 25, so that the rod 24 moves from the groove 23c to the groove 23d. While the operation member 6 is continuously pulled, the rod 24 reciprocates at the linear portion of the groove 23d, so that the locking claw 21 is maintained in a state inclined in the rotation direction. Thus, the long body 17 can be smoothly fed out again while the operation member 6 is being pulled.

On the other hand, when the force for pulling the operation member 6 is once loosened, the drum body 3 is rotated by the restoring force of the constant load spring 9 in a direction opposite to the direction of the arrow in FIG. When the stop piece 27 passes through the locking claw 21 and the locking claw 21 rotates in reverse by the restoring force of the return spring 25, the rod 24
It moves from 3d to the deepest part of the groove 23a. While the operation member 6 is being rewound, the rod 24 is
3a is reciprocated from one end to the other end.
Maintain the state inclined in the rotation direction. Thereby, since the drum body 3 and the shaft body 18 are rotated in the opposite direction, the operation member 6 is wound up, and the long body 17 is wound up on the shaft body 18.

However, also in this embodiment, the rotation of the drum body 3 is stopped by the stopper device 20 by pulling out the operating member 6 and then loosening it.
In order to hold the elongate body 17 at an arbitrary position,
May change the weight of the object, or it may catch the weight,
Even if the torque and balance of the drum body are lost by applying a constant load to the operation member 6, there is no problem.

In the second embodiment, the braking member 28 extending from the plate-like member 2b and covering the circumferential groove 5 of the drum body 3 is used, but is shown in the first embodiment instead. You may use the braking member 11 which has the hole which bent inside. Thereby, the elongate body pulling and winding apparatus 1 shown in the second embodiment can also draw and wind the elongate body by directly operating the elongate body as shown in FIG. It can also be used for a mold that can be used.

Based on the above configuration, the function of the long body pulling and winding apparatus 1 fixed to a wall or the like and having the shaft 18 attached thereto will be described.

When the operation member 6 is pulled, the drum body 3 and the shaft body 18 rotate, and the elongated body 17 wound around the shaft body 18 is extended, and the constant load spring 9 is wound around the drum body 3. Then, a restoring force is generated in the constant load spring 9 to rewind the drum body 7. Further, when the swing rod 34 rotates together with the drum body 3, the tip 35 of the swing rod 34 becomes the groove 3 of the ratchet groove 36 of the disc body 37.
6a and 36b are slid in the direction of the arrow. Thus, the distal end portion 35 of the swing rod 34 does not catch on the step, so that the elongated member 17 can be smoothly extended when the operation member 6 is continuously pulled.

Next, when the force for pulling the operating member 6 is relaxed, the constant load spring 9 is rewound from the drum body 3 to the drum body 7 by the restoring force, so that the drum body 3 rotates in the opposite direction.
The swing rod 34 rotates in the opposite direction together with the drum body 3. As a result, since the groove portion 36b is shallower than the groove portion 36a in the bent portion of the groove 36a, the distal end portion 35 of the swing rod 34 slides in the direction indicated by the arrow in the groove 36e deeper than the groove portion 36a. Is locked on the outer peripheral wall. Therefore, since the rotation of the drum body 3 and the shaft body 18 is stopped, the long body 1
7 can be held in any position.

Next, when the operating member 6 is pulled again, the tip end 35 of the swing rod 34 slides from the groove 36e to the groove 36f because the groove 36f is deeper than the groove 36e. The stop of the body 4 is released.

Further, when the operation member 6 is continuously pulled,
The oscillating rod 34 has a distal end portion 35 extending from the groove 36f to the groove 3f.
After moving to 6c, it slides in the direction of rotation of the drum body 3, and then slides in the direction of the arrow described above. Thus, the elongated body 17 can be extended again by continuing to pull the operation member 6 smoothly.

On the other hand, when the operating member 6 is loosened, the swinging rod 34 moves along the inner circumferential trajectory whose leading end 35 is formed by the grooves 36c, 36d and 35f starting from the groove 36f in the direction of the arrow. Move to. As a result, the drum body 3 and the shaft body 17 rotate in the opposite direction due to the restoring force of the constant load spring 9 being rewound from the drum body 3 to the drum body 7.
The operation member 6 and the elongated body 17 can be wound around the drum body 3.

However, also in this embodiment, the rotation of the drum body 3 is stopped by the stopper device 31 by pulling out the operating member 6 and then loosening it.
In order to extend and hold the elongated body 17 at an arbitrary position, there is no problem in changing the weight of the elongated body 17 or changing the load of the suspended object on the operation member 6.

In the third embodiment, the braking member 28 extending from the plate-like member 2b and covering the peripheral groove 5 of the drum body 3 is used, but is shown in the first embodiment instead. You may use the braking member 11 which has the hole which bent inside. Thereby, as shown in FIG. 3, it is possible to use the mold in which the elongated body can be drawn or wound by directly operating the elongated body.

[0059]

As described above, according to the first or second aspect of the present invention, when the weight of the extended portion of the elongated body and the restoring force of the spring are not balanced, or when the suspension is suspended. Even when the weight of the object does not balance with the restoring force of the spring, the vertical movement of the object can be stopped halfway.

According to the third aspect of the present invention, the state in which the operation member is always stretched by the braking means or the first state is provided.
Since the drum body is covered, it is possible to prevent the drum body from expanding in the radial direction at the time of rewinding. Therefore, it is possible to prevent the operating member from coming off the first drum body and the operating member from becoming entangled. Thus, the long body can be neatly wound around the first drum body.

According to the fourth or fifth aspect of the present invention, a braking member having a bent hole or a braking member covering the circumferential groove of the first drum body is provided as the braking means. Therefore, the operation can be assured and the structure can be simplified.

Further, according to the invention as set forth in claim 6 or claim 7, as the temporary stopping means, a stopper device having a revolving orbital cam and a rod, or a locking claw pivotally supported by a fixed portion is provided. A heart cam formed on the fixing portion, a rod having one end locked at a predetermined position of the locking claw, the other end slidingly contacting the groove of the heart cam, a return spring for pushing up the locking claw, and a rod. Is provided with a presser spring for preventing the spring from coming off from the groove of the heart cam and a plurality of locking pieces provided on the side surface of the first drum body. Having.
