Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in toilet paper holders.

Toilet paper holders for holding rolls of paper, generally consisting of a cylindrical cardboard core and an elongated strip of paper wrapped around the core, are well known.

Conventionally, this type of holder has a housing that accommodates the roll paper and a roll paper support shaft provided on both inner walls of the housing. During use, the roll paper is supported by the roll paper support shaft and the paper is separated from the roll paper. is played out. However, in such conventional toilet paper holders, when removing the core left on the support shaft after all the paper has been dispensed, the core must be broken or the support shaft must be moved so as to be pulled out from the core. . Therefore, there are disadvantages in that the work of removing the core is extremely complicated and requires time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a toilet paper holder that overcomes the drawbacks of the prior art as described above.

In order to achieve this object, the present invention is designed to automatically discharge the core of used roll paper from the housing as new roll paper is supplied.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

Referring to the drawings, there is shown a toilet paper holder embodying the present invention, which holder includes a generally cylindrical housing 10. A roll paper 11 is accommodated within this housing. The paper roll has the usual form of a cylindrical cardboard core 12 and an elongated paper 13 wrapped around the core. As will be described later, this roll paper is held at the feeding position A, which is the normal use position, by a roll paper support shaft (see FIG. 3).

The rear of the housing is provided with a bracket portion 14 which is attached to any wall of the toilet compartment by suitable means such as screws.

For example, on the bottom surface of this housing there is a supply port 15 for putting the roll paper 11 into the housing.
is provided. Further, the housing is provided with a roll paper supply passage 16 extending from the supply port to the delivery position A.

A paper cut portion 17 of a conventional structure is formed at the opening edge of the supply port on the front side of the housing. The paper 13 fed out from the roll paper at the feeding position is cut and used by this paper cutting section.

A discharge port 18 for the used roll paper core is provided on the upper surface of the housing, and a core discharge passage 19 extending from the feeding position to the discharge port is provided.

When all the paper is fed out from the roll paper at the feeding position, the empty core is discharged from the feeding position through the core discharge passage 19 as a new roll paper is inserted into the housing from the supply port 15, as will be described later. It is automatically discharged out of the housing through outlet 18.

A cover 20 is arranged to cover the outlet 18, and one end of this cover is pivotally attached to the housing. Therefore, this cover can open and close the discharge port.

Roll paper support shafts 30 are arranged on the inner wall of the housing on both sides of the roll paper so as to hold the roll paper 11 in the feeding position. This roll paper support shaft has an insertion portion 31 provided on the core discharge passage 19 side and inserted into the core 12, and a non-insertion portion 32 provided on the supply passage 16 side and not inserted into the core 12. There is. These inserted portions and non-inserted portions are connected by a smooth tapered surface 33, as shown in FIG. This roll paper support shaft is supported by the housing so as to be movable between a support position where the insertion portion 31 enters into the core and a detached position where it escapes from the core. Specifically, the support shaft is supported by a bearing 34 attached to the housing so as to approach or move away from the roll paper, and the support shaft is supported by a bearing 34 attached to the housing, and
1 is biased by a spring 35 so that it is always in the supporting position.

As will be described in detail later, as the roll paper inserted from the supply port 15 moves toward the feeding position, its upper end presses against the tapered surface 33 and the support shaft 30
is moved against the spring 35 in the direction shown by the arrow in FIG. 4 to bring it to the release position.

A cover locking means 40 that can lock the cover 20 to the roll paper support shaft 30 is provided. This cover locking means consists of a latch 41 integrally attached to the roll paper support shaft 30 and a latch engaging portion 42 provided on the cover so that the latch engages with the latch 41. This latch engaging portion is, for example, a hole 44 provided in a protruding portion 43 protruding from the inner surface of the cover.
A protrusion 45 provided at the tip of the latch fits into this hole. The latch protrusion 45 fits into the hole 44 when the roll paper support shaft 30 is in the support position, and exits from the hole when the support shaft is in the release position.

The operation of the above holder is as follows. First, as shown in FIGS. 3 and 4, the roll paper 11 is held at the delivery position by the roll paper support shaft 30, and the paper 13 is delivered from the supply port 15 and used. When all the paper has been fed out, a new roll of paper is slid into the supply passage 16 from the supply port 15. When the roll paper is further pushed up, the upper end of the roll paper comes into contact with the empty core on the support shaft 30, causing the empty core to rise. As the empty core rises, the support shaft moves to the detached position, the empty core falls off from the support shaft, and the new roll paper moves further upwards through the core discharge passage 19 toward the discharge port. At the same time as the empty core heads toward the outlet, the new roll paper pushes against the support shaft 30 to hold it in its release position. At this time, the protrusion 45 of the latch 41 has fallen out of the hole 44. When the roll paper is further raised, the empty core pushes up the cover 20 and is discharged from the discharge port 18 to the outside of the housing, as shown in FIGS. 5 and 6. At the same time, the new roll paper is located at the unwinding position and the insertion portion of the support shaft protrudes into the core to be held at the unwinding position.
The paper is then fed out and used as described above.

According to the present invention, empty cores are automatically discharged as new roll paper is supplied, which is very convenient.
