DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the accompanying drawings. 1 to 7 show an automatic tissue paper lifting mechanism according to a first embodiment of the present invention.

FIG. 1 shows an automatic tissue paper lifting mechanism 10
FIG. 9 is a schematic longitudinal cross-sectional explanatory view of a box body formed of a slightly rigid cardboard having a thickness of about 1 mm to form an oblong shape with four side walls A, a top wall B, and a bottom wall C as shown in FIG. 7. A large number of tissue papers 14 are stored in a stack 12 in the stack 12. A drawer 16 is provided along the longitudinal direction of the upper wall B of the box 12 along the longitudinal direction of the box, and the tissue papers 14 are usually drawn out one by one from the drawer.

The tissue papers 14 housed in the box 12 are laminated so as to alternately sandwich the folded papers in a substantially bag-like shape, and as a result, as shown in FIGS. When the tissue paper 14 is pulled out, the upper paper piece 18 of the next tissue paper 14 projects from the drawing outlet 16, and the paper is successively drawn and used while pinching the projected upper paper piece.

A characteristic of the present invention is that the box 12
That is, the push-up device 20 is provided in the lower part of the entire tissue paper 14. As will be described later, the push-up device 20 is provided on the lower surface of the tissue paper located below the stacked tissue paper 14 and pushes up the entire tissue paper from below.

In FIGS. 2 and 3, the push-up device 20 according to this embodiment is formed of a slightly stiff cardboard having a thickness of, for example, about 1 mm, like the box body. Due to the nature of a tissue paper storage box, the point is that it is a thin plate, and the material may be plastic or light metal. The push-up device 20 is normally disposed on the lower surface of the tissue paper located at the bottom, and has a rectangular flat plate-shaped mounting portion 22 for mounting the stacked tissue paper on the upper surface, and a lower portion of the mounting portion 22. And a rectangular flat plate-shaped main leg 24 fixed to or engaged with the mounting portion 22 and a rectangular flat plate-shaped main leg 24.
Sub leg 2 that cooperates with 4 to support the mounting portion 22 in a substantially horizontal state
6, the main leg 24 and the auxiliary leg 26 or these and the mounting portion 2
And a biasing member 28 hung between the two.

A bent portion 32 is provided at an end of the main leg 24 so as to form a bent end 30 having an oblong shape, and the bent end 30 is formed so as to be bendable. The bent end 30 of the main leg 24 is attached and fixed to the lower surface of the mounting portion 22 so as to be orthogonal to the longitudinal direction of the mounting portion 22. In addition, a cut groove 34 is formed in parallel with the longitudinal direction of the bent end 30 in a substantially central portion of the main leg 24 to a certain depth.

On the other hand, the auxiliary leg 26 has a bent end 3 from the main leg 24.
It is formed in the same shape as the portion excluding the 0 portion, and is at a substantially central portion of the sub leg 26 at a position corresponding to the cut groove 24 of the main leg 24 and so as to face each other. Notch grooves 34 are also formed at various positions by engraving to a certain depth. Then, as shown in FIGS.
4 and the auxiliary leg 26 are engaged with each other so that the cut grooves 34, 34 are meshed with each other, and are combined in an X shape so as to form a line of intersection 36 at this meshing portion. Then, on both side surfaces of the intersecting line portion 36, adhesive tapes 38 are attached along the longitudinal direction thereof so as to groin above and below the intersecting line portion 36 in order to maintain the meshed state of the leg portions 24 and 26. It is worn. As a result, the legs 24 and 26 operate in a proportional compass manner with the intersection 36 of the cut grooves 34 and 34 serving as a pivot or a fulcrum, and their ends move up and down relative to each other.

In this embodiment, as shown in FIG.
Two pairs of short parallel cuts 40, 40. are formed at the lower ends of the main leg 24 and the auxiliary leg 26. ． ． Are formed, and the locking portion 42 is formed. Then, the notches 4 of the main leg and the auxiliary leg that face each other, respectively.
A rubber member 44, such as a rubber band, as a biasing member 28 is hung and engaged with 0, and the lower ends of both legs 24 and 26 are elastically biased toward each other. As a result, the installation part 22 is always biased upward. In this way, it is possible to move up and down as a whole in a pantograph manner with the intersection 36 of the cut grooves 34, 34 as a fulcrum.

Note that, for example, in FIG. 3, a bent end 30 may be formed on the side of the auxiliary leg 26 and the side of the auxiliary leg may be fixed to the lower surface of the mounting portion 22. In addition, as an X-shaped assembling mode of the main leg 24 and the auxiliary leg 26, as shown in FIG. 8, the auxiliary leg 26 is formed to have a narrow lateral width and is fitted in the center of the inside of the main leg 24 in the width direction. The groove 46 is pierced, and the auxiliary leg 26 is inserted into the fitting groove 4
It may be fixed to an adhesive tape or the like at a position where it penetrates 6 and forms an X-shape. Alternatively, as shown in FIGS. 9A and 9B, slit grooves 48 are formed on both sides of the main leg 24, and the slits 48 are inserted on both sides of the upper portion of the auxiliary leg 26 so that the slit grooves 48 can be inserted. It is also possible to cut out the upper center of the sub leg 26 so as to form the plate 50, and form the main leg and the sub leg in the slit groove 48 by assembling them in an X shape. Further, as shown in FIGS. 10 (a) and 10 (b), the slit insertion groove 50 is provided in the substantially central portion on either side of the main leg 24 or the auxiliary leg 26 and can be inserted therein. It is a good structure.

In each drawing, the mounting portion 22, the main leg, the auxiliary legs 24, 26, etc. forming the push-up device 20 have an unnatural thickness width in terms of balance with the entire box 12 for the purpose of facilitating understanding. Although it is described thickly, in reality, the box body 12 is normally vertical,
The width and height are formed to be about 11.5 × 24.8 × 8.3 (cm), and as shown in FIG. 5, the push-up device 20 is forcibly pushed down and folded up to form a tissue. When the paper 14 is fully accommodated in the box 12, the push-up device 20 is folded into a thinner shape than shown in the figure, and therefore is extremely lightweight because it is made of paper, and at the same time the paper is accommodated. It is possible to secure sufficient space.

The embodiment shown in FIG. 6 shows a case where the push-up device 20 according to the above-mentioned embodiment is used by being stacked in two stages. In this case, when the elastic force of the rubber member 44 is set so as to correspond to the pushing-up force of the tissue paper of one box, the paper of two boxes is made to smoothly project the paper piece of the next paper. Since it is pushed up by such an elastic push-up force, it is possible to form a deep type storage box in which the number of sheets of paper stored is much larger than in the conventional case.

When manufacturing and using this automatic tissue paper pushing-up mechanism 10, first, as shown in FIG. 5, the pushing-up device 20 is accommodated in advance in the box 12 with the mounting portion 22 facing upward. While pushing down the mounting portion 22 against the elastic contracting force of the biasing member 28, that is, the pushing-up force, the paper storage portion is formed and the tissue paper is stored to the full state. In this state, as shown in FIG. 5, the mounting portion 22 of the push-up device is completely pushed down and the entire device 20 is expanded and contracted and held in a flat plate shape. From this state, the uppermost tissue paper 14 is pulled out from the outlet 16 and used. In successive use, when the tissue paper is pulled out by a known stacking method of sandwiching papers with each other, the upper paper piece 18 of the next paper is projected outward from the outlet 16.

The elastic contraction force of the rubber member 44, such as a wheeled refuse of the push-up device 20, of the box body 12 when the remaining tissue paper at the lowermost portion becomes about one third to one quarter. The height of the mounting portion 22 is set to be displaced to about 80 to 90% of the height. That is, at this height position, the elastic force of the rubber member 44 is set so that no load is applied to it. Therefore, when the mounting portion 22 is pushed down from this, the main leg and the auxiliary leg 2 are set with the intersection line portion 36 as a fulcrum.
4, 26 are folded, and at this time, the rubber member 44 exerts elastic contraction force. As a result, as the paper is pulled out one by one from the full state, the appropriate elastic push-up force acts, and the projection action of the paper piece of the next paper is surely performed until the last one sheet,
In addition, it is possible to pull out one by one very smoothly.

Particularly, in the push-up device in the embodiment,
The entire device is made from a slightly stiff paper, the structure is extremely simple, and the device can be made at a very low cost in terms of the material made of paper. Therefore, the tissue paper storage box itself can be compared. It can be applied to low-priced products to improve its added value.

When the amount of paper gradually decreases during use, the urging member 28 causes the main leg and the sub-legs 24, 2 to move.
6 cannot be pushed up, simply by reversing the entire box body 12, the contracting force of this urging member immediately acts to push up the placing portion 22 and thus the entire tissue paper 14 upward. be able to. Also,
It is also possible to insert colored paper at a desired tissue paper height position as a timing indicating the timing of the reversal and to reverse the box when the colored paper is seen during successive use.

Next, another embodiment of the automatic tissue paper pushing-up mechanism according to the present invention will be described. The same members as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

A second embodiment is shown in FIGS. 11 to 13. In this embodiment, the main leg and the auxiliary leg are assembled in an X shape, and the main leg is provided between the intersection line portion 36 and the biasing member 28 provided at the lower end of each leg 24, 26. A lift stop device 52 is provided for restricting the position where the height of the leg is the highest due to the vertical movement of the auxiliary leg. That is, the bent end 54 is fixed to the inside of the main leg 24, and the bent end 5
A horizontal plate 56 is connected to 4 so as to be bendable.
In addition, the auxiliary leg 2 corresponding to the mounting position of the bent end 54 is almost the same.
A stopper member 58 is fixed to the inner position of 6, so that the end portion 56a of the horizontal plate 56 is in a free state when the entire push-up device is contracted by applying a load from above as shown in FIG. Release the load from above and remove each leg 24,
In the state where the mounting portion 22 is pushed upward by 26, as shown in FIG. 12, the horizontal plate end portion 56a is restricted from moving along the inner side of the auxiliary leg 26 by the stopper member 58, and is held in a substantially horizontal state. To be done.

Here, in the pantograph-like vertical movement of the main leg 24 and the auxiliary leg 26 about the intersection line 36 as a pivot,
The position where the height of the leg is the highest is restricted, so
The tissue paper 14 mounted on the mounting portion 22 remains less in the box body 12, is pressed strongly against the ceiling portion of the inner surface of the box body 12 and becomes difficult to take out, and when the taken out tissue paper is taken out, The drawback of tearing will be eliminated.

Further, in the present embodiment, the lifting stop device 5
An initial lift assisting member 60 is provided on the upper surface of the second horizontal plate 56. The initial lifting assisting member 60 is formed in a solid box shape made of, for example, an elastic material having high expandability such as sponge. In the initial lift assisting member 60, the fulcrum as the pivot of the intersection 36 is formed by the rubber member 44 as the urging member 28 when the push-up device 20 is contracted as shown in FIG. 5 in the first embodiment. Therefore, the box body 1 is placed in such a position that it overlaps the straight line portion.
In the case where the tissue paper in 2 is gradually used and the load is also gradually reduced, the lifting operation of both legs by the biasing member 28 may not be performed. In order to prevent this, the initial lifting assisting member formed of an elastic body on the upper surface of the horizontal plate 56 is assumed to elastically raise the position of the intersecting portion 36 as the load is gradually reduced by compressing the push-up device 20. By attaching 60, this can be achieved. That is, the initial lifting assisting member 60 is provided to assist the initial lifting operation of the main leg 24 and the auxiliary leg 26.

Therefore, it suffices to lift the intersecting line portion 36 as much as possible, and the initial lifting assisting member 60.
The mounting position of is not limited to the upper surface of the horizontal plate 56, and the mounting position of FIG.
As shown by the chain line, the inner surface of the main leg 24 on the lower side of the intersecting line portion 36, the inner side surface of the corresponding sub-leg 26 corresponding thereto, and the outside thereof, and the inner side of the upper side of the intersecting line portion 36. It may be attached to the outside or the lower surface of the mounting portion 22.

In addition, in this embodiment, the push-up device 20 is provided with the tilt preventing means 62. Figure 1
In 1, 12, and 13, the main leg 24 is fixed to the lower surface of the mounting portion 22 such that one end thereof is bendable, and the sub leg 26 is
The upper end of the is engaged displaceably with the lower surface of the installation portion 22. Further, the push-up device 20 is provided with a tilt stopping means 62 for preventing the mounting portion 22 from tilting in one direction by separating from the sub leg 26. The inclination preventing means 62 has the auxiliary leg 26, the engaging portion 22a on the lower surface of the mounting portion, and the other end side 22b with the attachment portion of the bent end 30 of the main leg 24 to the mounting portion 22 as the center.
It has a bent end 64 that is fixedly adhered to and a bent plate 66 that is flexibly connected to the bent end 64.

The thrust plate 66 has a required length, and the tip 66a of the push-up device 20 is in a free state when the pushing-up device 20 is contracted as shown in FIG. As the heights of the legs and the sub-legs become higher and the intersecting line portion 36 also becomes higher, the tip portion 66a thereof approaches the intersecting line portion 36, and further, the intersecting line portion 36 and the tip portion 6 of the veneer 66.
Since the bent end 64 and the mounting portion 22 are flexibly fixed when the 6a abuts on each other, the mounting portion on the side 22a of the auxiliary leg 26 is prevented from tilting upward (lifting and tilting). As a result, in the embodiment shown in FIG. 6, when a box body having a deep depth is formed and the push-up device 20 is used by being stacked in two stages, one of the mounting portions of the push-up device located in the lower stage is lifted up. It is possible to prevent it from being tilted and fallen and not functioning in the box body. As a result, the mounting portion 22 does not tilt and is stable, so even when two or more push-up mechanisms are stacked and used. The push-up device operates stably.
