Description

Manual toilet cover winding device {Hand powered apparatus to wind commode cover}

The present invention relates to a manual toilet cover winding device, and more particularly, while the pull reel and the recovery reel is always rotated at the same ratio, the rotational force is transmitted to the recovery reel side through a disk having a pad to wind the sanitary cover to an appropriate length. In this case, it is possible to stabilize the operation by slipping without rotating any more.

As you know, toilet seats installed in facilities used by many people, such as subways, bus terminals, factories, stations, hospitals, restaurants, and lodging facilities, are unpleasant and do not know who used them before. In view of this, the toilet seat assembly was automatically supplied with a toilet cover that was automatically covered by a motor with a sanitary cover made of vinyl tube on the seat. Due to the adoption of water cleaning, it could lead to an inoperable state of the motor, which caused the increase in manufacturing cost due to the expensive members.

By improving these problems, registered utility model No. 150997 solves the problem of inoperability due to motor recruitment and increase in manufacturing cost by manually winding the handle handle by rotating the handle handle by connecting the handle handle and recovery reel. The toilet seat assembly has been disclosed. However, since it was necessary to rotate the handle handle indispensable to wrap the sanitary cover, in case of a physiologically urgent situation, the handle handle can not be returned and the handle handle must be returned to some extent. I could not know whether the sanitary cover is completely covered on the seat, and the sanitary cover may be checked by the unit of length covered on the seat before winding on the supply reel, but in this case, a separate process is added. Cannot afford to check these lengths individually It can be said to be self-evident.

Therefore, the present applicant in the Utility Model Registration Application No. 2001-34815, the one side is fixed and the other side is open on the left side, the open side of the left side is formed on the supply reel wound around the sanitary cover, and formed on the fixed side of the left side In the structure of the recovery reel which winds up the sanitary cover, the pull reel is mounted in front of the recovery reel, the lever is rotatably mounted on the side of the recovery reel, and the arc-shaped drive gear is fixed to the lever to relay the gear. The gears are engaged with the driven gear pressed into the shaft of the pull reel, and the relay gear is composed of a "┤" -type movable gear having a gear in the center and a fixed gear fitted to the movable gear. The ratchet protrusions inclined in the rotational direction are radially formed on the contact surface, and the ratchet action is selectively provided on the rear of the movable gear via a compression coil spring. By forming the driving pulley integrally, the belt is loosely connected between the driving pulley and the driven pulley pushed into the shaft of the recovery reel, so that the entire sanitary cover can be covered by one lever pressing operation, so that convenience can be used. Since the power is no longer transmitted by the ratchet action between the gears even when the lever is in the original position, the sanitary cover once wound on the recovery reel is not loosened to improve reliability, and the belt is loosened between each pulley of the pull reel and the recovery reel. When the hygienic cover pulled by the pull reel is connected to the recovery reel is connected, the recovery reel is not rotated any more, it has disclosed a manual toilet cover winding device that can always perform a stable winding operation.

However, the manual toilet cover winding device according to the Utility Model Registration No. 2001-34815 is loosely connected to the belt between the driving pulley pressed into the shaft of the pull reel and the driven pulley pushed into the shaft of the recovery reel. Until the pulled sanitary cover is wound on the recovery reel, the rotational force is transmitted, but when the sanitary cover is wound on the recovery reel, the rotational force is slipped so that it cannot be rotated anymore, so that a stable winding operation can be always performed. In order to achieve this smoothly, the belt and each pulley must have a certain amount of friction to transmit the rotational force until the sanitary cover pulled by the pull reel is wound on the recovery reel. The belt width is narrow so that the contact area with each pulley can be achieved. Because of this small size, torque transmission and slip operation are not performed smoothly. Was generated, if the belt is worn for a long time use, do not you get to keep the tension because there were issues that haejueoya often replace the belt.

In addition, the fixed gear and the movable gear which perform the ratchet operation are plate-shaped, so that the interlocking area between the ratchet protrusions is small and the fixed gear is only engaged with the driven gear, so the fixed gear and the movable gear are not perfectly fixed. If the ratchet operation is not smooth and force is applied between the fixed gear and the movable gear, there is a problem with the wheels. One end of the lever is rotatably fixed, and when the lever is rotated, power is transmitted through the arc-shaped driving gear. The power transmission relationship is complicated and less force, so the user had to press the lever with a strong force.

The present invention has been proposed in view of this point, and the center of rotation of the lever is positioned at the center of the ratchet wheel, which is selectively engaged with the drive gear, so that it can be easily operated even with a small force, and the ratchet protrusion is formed inside the drive gear. And the ratchet wheel having the ratchet pin corresponding to the ratchet protrusion is inserted into the fixed gear so as to be in contact with the ratchet protrusion so that the ratchet protrusion and the ratchet pin contact each other in the direction perpendicular to the rotation axis to facilitate the ratchet operation. A driving wheel and a driven wheel are respectively formed on the shaft, and a timing belt is applied therebetween so that the rotational force of the same ratio is always transmitted. A disk having a pad integrally with the driven wheel is provided to be rotatably inserted into the shaft of the recovery reel. And the other disks corresponding to the disks are fixed to the shaft of the recovery reel so that each disk is frictionally connected to each other. To the contact area of the pad provides a more manual toilet cover take-up device capable of obtaining a friction force as desired it is an object.

Hereinafter, the present invention will be embodied through the examples presented.

Manual toilet cover winding device according to the present invention is a body (1) located at the rear of the toilet, as shown in Figures 1 to 3, the base (2) is fixed to the other end is not fixed at one end to the main body (1), The sanitary cover 3 made of a vinyl tube is wound around the feed reel 4 which is rotatably installed on the left end of the main body 1, and is installed on the left fixed end of the main body 1 and supplied from the supply reel 4. Recovery reel 5 winding the sanitary cover 3, the cutter 6 is located on the fixed end side of the pedestal (2) to rotate both sides of the sanitary cover (3), rotating to the front of the recovery reel (5) A pull reel 8 which is attached to the lower bobbin 7 and pulls the sanitary cover 3 between the lower bobbin 7 and the rear side, and is rotatably mounted on the recovery reel side of the main body 1 by a plurality of gear groups. In constructing a toilet cover winding device including a lever (9) to wind the sanitary cover (3) by rotating the recovery reel (5) and pull reel (8) , The driving wheel 10 is press-fitted and fixed to the shaft of the pulling reel 8, and the driven wheel 11 having a smaller diameter than the driving wheel 10 is rotatably inserted into the shaft of the recovery reel 5, A disk 14 provided with a pad 13 integrally with the driven wheel 11 to transmit rotational force at a constant speed by connecting the drive wheel 10 and the driven wheel 11 with the timing belt 12. ) Is inserted into the shaft of the recovery reel (5) so as to be idle, and the other disk 15 corresponding to the disk 14 is fixed to the shaft of the recovery reel (5) between each disk (14, 15) The rotational force is selectively transmitted by the friction force, and a tension adjusting knob 16 is provided at the shaft end of the recovery reel 5 so as to closely contact the disks 14 and 15. The compression spring 17 is interposed between the driven wheels 11 and the inner side of the tension adjusting knob 16 is in contact with the compression spring 17 separately from the compression spring 17. Inserting a bearing 18 which rotates, and is standing in the combined or the adjusting nut 19 for adjusting the position of the tension adjustment knob 16 and the bearing 18 to the shaft of the recovery reel (5).

At this time, the gear group has the largest diameter driving gear 20, the small diameter gear 21a and the large gear 21b are integrally formed so that the small diameter gear 21a is engaged with the driving gear 20 to rotate. The diameter of the relay gear 21 and the relay gear 21 is smaller than that of the gear 21b having a larger diameter, and is formed coaxially with the pull reel 8 so that the diameter of the relay gear 21 is larger than the gear 21b. It consists of a driven gear 22 to rotate and pull the reel (8) while being engaged in the same direction as the drive gear (20), the ratio of each gear is about 90 ~ 100cm overall length of the base (1) lever When the driving gear 20 is rotated about 7 cm by rotating (9), the recovery reel 5 should be properly configured to extend about 13 times so that the recovery reel 5 can be rotated about 9 turns to wind about 90 cm.

In addition, the drive ratchet device is also configured to prevent the reverse rotation so that the sanitary cover (3) already wound on the recovery reel (5) is not released, and only when the lever (9) is pressed, the sanitary cover (3) can be wound. This forms a ratchet groove 24 in which the ratchet protrusions 23 are formed on the inner circumferential surface of the drive gear 20 in a concentric manner, as shown in FIG. 4, so that the ratchet wheel 25 is inserted, and the ratchet wheel 25 is inserted therein. ) Is formed at equal intervals in the edge portion of the ratchet operating grooves 26 inclined in the forward rotation direction at regular intervals, and in each ratchet operating groove 26, the ratchet protrusions 25 are driven by being engaged with the ratchet protrusions 23 during forward rotation. An asymmetrical ratchet formed to fit the internal shape of the inclined portion side of the ratchet operating groove 26 so that the gear 20 is rotated together and the ratchet protrusion 25 can be rotated while the ratchet protrusion 23 is overturned during the reverse rotation. Insert the pins 27, respectively, can push the ratchet pins 27 in the direction always heard Above the pin after the ratchet 27 of the ratchet lock operation groove 26 is hayeoseo via a compression spring (28).

In addition, the lever 9 is fixed to the rear surface of the ratchet wheel 25 in order to receive a greater force so that the center of rotation of the lever 9 and the center of rotation of the drive gear 20 is the same, the lever Between the one side of the (9) and the frame of the main body 1 through the spiral spring 29 to release the pressure while pressing the lever 9 is configured to automatically return to the original position.

Manual toilet cover winding device according to the present invention configured as described above acts as follows.

First, take out the sanitary cover (3) wound on the supply reel (4) and cover the entire base (2) through the free end of the base (2), and then cut both ends of the sanitary cover (3) through the cutter (6) Passing between the pull reel (8) and the bobbin (7) in one state to be fixed to the recovery reel (5) is ready.

When pressing the lever 9 in this state, the lever 9 is rotated about its fixed end, and the fixed end of the lever 9 becomes a ratchet wheel 25 so that it can receive a large force even with a small force. It will be simple and easy.

When the ratchet wheel 25 is rotated, as shown in FIG. 5A, the ratchet pin 27 lifted by the rear compression spring 28 meshes with the ratchet protrusion 23 and is engaged with the ratchet wheel 25. The drive gear 20 may be rotated in the same direction, and the rotational force is transmitted to the driven gear 22 through the relay gear 21 to rotate the pull reel 8 in the same direction as the pressing direction of the lever 9. Accordingly, the sanitary cover 3 is pulled while cutting both sides by the front cutter 6 in a state sandwiched between the pull reel 8 and the bobbin 7.

Since the ratchet operation is made in a direction perpendicular to the rotation axis, the ratchet wheel 25 may be stably made at any external force unless the ratchet wheel 25 is removed from the ratchet groove 24.

At this time, since the ratio of each gear is configured to rotate the pull reel 8 by extending the rotation length of the initial drive gear 20 by about 13 times, the sanitary cover 3 may cover the entire base 2. The driving wheel 10 of the pull reel 8 and the driven wheel 11 of the recovery reel 5 are connected to the timing belt 12 so that the recovery reel 5 is pulled 8. The sanitary cover (3) is pulled and wound on the recovery reel (5) while rotating in the same direction.

By the way, the driven wheel 11 is not strictly fixed to the axis | shaft of the collection reel 5, but forms the disk 14 in which the pad 13 was attached integrally with the driven wheel 11, and collect | recovers the reel. It is rotatably inserted into the shaft of (5), and the other disk 15 corresponding to the disk 14 was fixed to the shaft of the collection reel 5, and it collect | recovers in order to contact between each disk 14 and 15. Since the tension adjustment knob 16 is provided at the shaft end of the reel 5 and the compression spring 17 is interposed between the tension adjustment knob 16 and the driven wheel 11, as shown in FIG. When the sanitary cover 3 drawn by the pull reel 8 is wound through the reel 5, the reel 5 is rotated together with the pull reel 8 by the friction force between the disks 14 and 15. After the sanitary cover 3 is wound up through the recovery reel 5, the discs 14 and 15 may slip between each other (actually indistinguishable from the naked eye). As the sanitary cover (3) is wound on the recovery reel (5), even if the diameter of the recovery reel (5) gradually increases, it is possible to always perform a stable winding operation, in particular the pad (13) Since the power is transmitted by the contact between the disks 14 and 15, the contact area is increased so that sufficient contact force can be provided. The diameter of the recovery reel 5 without the sanitary cover 3 being wound is obtained. Since the driving reel 10 is smaller than the diameter of the pulling reel 8, the driving wheel 10 is formed larger than the driven wheel 11 so as to perform a smooth winding operation, and the pulling reel 8 is capable of performing a smooth pulling operation. It is composed of rubber coated on the outer surface.

In addition, even if the pad 13 wears little by little using the apparatus according to the present invention for a long time, the disk 14 is continuously pushed by the compression spring 17 so that it can always have a stable power transmission performance, and tension as necessary Adjusting the tension (16) by turning the tension can be adjusted so that it can be used for a long time without replacing the member.

On the other hand, while pressing the lever 9 and the spiral spring 29 interposed between the one side and the frame of the main body 1 is tightened, the state is inherent in the elastic force, so to release the pressure while pressing the lever (9) Then, the lever 9 may be returned to its original state while the spiral spring 29 is released. At the same time, the lever 9 is returned to its original position and the ratchet wheel 25 to which the lever 9 is fixed is also reversed.

When all the gears are engaged in the reverse rotation of the ratchet wheel 25 in the reverse rotation, the sanitary cover 3 wound around the recovery reel 5 may be released, so the ratchet wheel 25 and the driving gear 20 according to the present invention. It is configured to ratchet between the ratchet grooves 24 of), when the ratchet wheel 25 is reversely rotated as shown in FIG. 5B, the ratchet pins 27 are ratchet protrusions 23 of the ratchet grooves 24. ) Is rotated as it is, but the drive gear 20 does not interfere, so the reverse rotation does not affect the drive gear 20, so the pressed lever 9 can be returned to its original position while being recovered. The sanitary cover (3) wound on the reel (5) is not reversed to release, and when another user presses the lever (9) returned to its original state, the above operation is repeated.

As described above, the present invention is a fixed part of the lever, that is, the center of rotation becomes the center of rotation of the drive gear can be operated smoothly even if you press the lever with a small force is convenient and easy to use, and then press the lever When the pressure is released, it can be returned to the original position by the spiral spring, so it can be easily used by the user next time. When the lever is pressed, the ratchet pin and the ratchet protrusion can be caught and the power can be transmitted. This ratchet protrusion is prevented from reverse rotation, and of course, the ratchet action is performed in a direction perpendicular to the rotation axis, so that a stable power transmission function can be performed at all times, and a timing belt is provided between the pull reel and the recovery reel. Disc with pads to receive the rotational force of the recovery reel while transmitting rotational force at constant speed As it is configured in a type, as each disk comes into contact with a large area, sufficient friction can be obtained as desired, so that a stable winding operation can be performed at all times, and the disk is continuously pushed through the compression spring, and the tension adjustment knob According to the tension can be adjusted accordingly can perform a stable power transmission function as well as a very useful effect that can be used for a long time without replacing the member.
