Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention belongs to the field of sanitary equipment and relates to a toilet paper holder that can automatically replace toilet paper.

(Prior art) Most of the toilet paper holders that have been used in the past require the toilet paper to be replaced manually, so there are types that automatically replace the paper, but their operation is uncertain. Therefore, there is a need for a holder that can be easily and reliably replaced.

(Problems to be solved by the invention) This invention aims to provide a toilet paper holder that can automatically and reliably replace toilet paper with a single touch.

(Means for solving the problem) This invention is to make the locking pawl and the actuating pawl, which are arranged in an L shape with respect to the left side wall, on the left and right side walls of the lower part of the box having the required width, so that they can rotate freely and rotate to the left. The locking mechanism is capable of restoring freely and has an operating claw protruding inward from the left side wall at the restoring end in an unloaded state, and the right side wall is in an inverted L shape, that is, the locking is integrally provided symmetrically with the L shape. The pawl and the operating pawl are locked so that they can rotate freely and can be rotated clockwise and restored, and in the same way, the actuating pawl is made to protrude inward from the right side wall at the unloaded restoring end, and a slider is installed on one side wall of the middle part of the box. A stopper is installed horizontally so that it can be moved in and out inside the box, and a lever that swings back and forth is linked to the left and right sides of the rear of the box, and the lever is pressed forward as required and its tip is hook-shaped to operate the left and right. It is secured to a claw so that it can be freely restrained and released. Here, the locking claw and the operating claw arranged in an L shape are fixed at a phase of 90 degrees with respect to the locking shaft, and the locking claw and the operating claw are fixed.
The locking shaft is fixed with a claw structure that rotates together with the locking shaft, and the integrated locking claw and operating claw are rotatably engaged with a phase of 90 degrees with respect to the locking shaft. The phrase "freely rotated to the left and restored", which includes a claw structure, means that an object that has been rotated to the right under load can be rotated to the left by the elastic force of a torsion spring, etc., and returned to its original position under a predetermined mounting load. , right rotation restoring function refers to the same function as above, only the control direction is different.

(Function) According to the above configuration, by simply operating the slider with a single touch, the used up winding core is released from the locking pawl by the restoring force of the spring, and the spare toilet paper is dropped, and it is attached to the locking pawl by its own weight. Lock automatically.

(Example) To specifically explain this invention with an example,
As shown in Fig. 1, a box 2 has a space for horizontally storing toilet paper 1 (hereinafter referred to as roll paper 1).
A locking shaft 4 is horizontally and rotatably supported in a direction perpendicular to the axis of the winding core 3, and each locking shaft 4 has an L shape or an inverted L shape as shown in FIG. In other words, the locking claws 5 and the operating claws 6 are locked together symmetrically with a 90° phase. Left side locking shaft 4
A return spring 7 is secured to the right locking shaft 4 so as to be able to return to the left rotation direction, and a return spring 7 is retained to the right locking shaft 4 so that the return spring 7 can be restored to the right rotation direction. That is, in a loaded state (when the roll paper 1 is in use), the locking pawl 5 on the left side wall protrudes horizontally inward against the reaction force of the return spring 7 due to the load, and the operating pawl 6 engages with the locking pawl 5. It is hung at a position outside the width of the roll paper 1 at an angle of 90 degrees. As shown in FIG. 1, on the right side of the axis of the left locking shaft 4, on the inside of the box, there is an operating claw 6 that hangs down, and as shown in FIG.
The hook 9 of the left lever 8 shown in FIG. 3 engages between the inner side wall of the box and the actuating pawl 6 in the constricted portion 17 formed by the shaft mounting, thereby maintaining the above-mentioned posture of the engaging pawl 5 and the actuating pawl 6. Similarly, on the right side wall, the locking pawl 5 protrudes horizontally inward against the reaction force of the return spring 7, and the operating pawl 6 is moved outward from the width of the roll paper 1 at an angle of 90 degrees with the locking pawl 5. It is suspended at the position of . The right lever 10 shown in FIG.
The hook 9 is locked to maintain the posture, and the winding core 3 of the roll paper 1 is locked to the left and right locking claws 5.
Spare roll paper 1 is placed above the roll paper 1 in use.
is locked and on standby by a stopper 11, which will be described later, which protrudes from the left side wall. Now, when the roll paper 1 in use is completely used up, as shown in FIG. When the lever is slid in the direction shown in FIG. 5, the pin 13 integrated with the slider 12 pushes back the left lever 8 shown in FIG. At the same time, the stopper 11, which is connected to the upper part of the slider 12 with a pin 19 and loosely inserted into the left side wall, is also pulled out of the box. Here, the left lever 8 is integrated with the rotation shaft 14, and the torsion spring 15, which has one end fixed to the left lever 8, has its other end fixed to the left side wall of the box 2 so as to push the left lever 8 back forward. Since the rotation shaft 14 also integrates the right lever 10, the left lever 8 and the right lever 1
At the same time, the hook 9 integrated at the tip of the hook 9 is released from the left and right operating claws 6, respectively. At the moment of release, the left locking pawl 5 rotates counterclockwise and returns to its original state due to the respective return springs 7, and the right locking pawl 5 rotates clockwise and returns to its original state, resulting in the state shown in FIG. At this time, the winding core 3 is flipped upward by the locking pawl 5, slips away from the locking pawl 5, loses its support, and falls, and at the same time, the spare roll paper 1, which has lost the support of the stopper 11, falls from above. , acts to push down the operating claws 6 horizontally protruding inward from the left and right side walls, the left operating claw 6 rotates clockwise against the return spring 7, and the right operating claw 6 similarly returns. It rotates counterclockwise against the force of the spring 7, and at this time the locking claws 5, which are integrated with the respective operating claws 6 at a 90° phase, project inward. The dimensions and shape of the locking pawls 5 have been experimentally selected so that they can be easily attached to and removed from the winding core 3, so that each of the locking nails 5 enters into the winding core 3 and rolls paper 1, as shown in FIG. to lock. When you release your finger from slider 12, torsion spring 1
5, the right lever 10 also swings forward via the left lever 8 and the rotating shaft 14, returning the slider 12 to its original position and locking the hook 9 to the constriction 17 of the operating claw 6. At this time, the stopper 11, which is swingably pin-bonded to the slider 12, also has its tip protruding inward from the left side wall. Lid 16 of in-use box 2 of roll paper 1
By simply opening the opening and replenishing the spare roll paper 1 as appropriate, the roll paper 1 can be easily and reliably replaced by one-touch operation of the slider 12 as described above.

(Effects of the invention) As described above, according to this invention, by one-touch operation of the slider, the used winding core, which has become light due to the reaction force of the return spring, can be flipped upwards and removed, and at the same time, the spare winding core can be removed. The roll paper is dropped from above and the locking pawl is locked to the winding core by its own weight, and this locking mechanism works in conjunction with the working pawl while catching the roll paper falling under its own weight with the working pawl. Since the claws are activated, the roll paper can be easily and reliably locked to the locking claws.
