Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a roll-type wrapping paper holder such that a roll-type wrapping paper such as a toilet paper roll is rotatably installed.

[0002]

[Prior Art]

 Such a holder is known from Japanese Utility Model Laid-Open No. 58-156496 proposed by the present applicant. The main body of this holder has left and right side walls facing each other and protruding from both sides of a fixed substrate fixed to a wall surface, and both side walls have circular cavities facing each other at their tips. In order to rotatably attach the roll-type wrapping paper horizontally to the holder body, the roll-type wrapping paper that is stretchable and normally urged in the extended state and longer than the facing distance between the both side walls penetrates the center of the roll-type wrapping paper. Then, put the ends of the erection core projecting from both ends of the roll-type wrapping paper into the circular recesses at the tips of both side walls of the main body.

[0003]

[Problems to be solved by the device]

 However, since the length of the erection core where each end protrudes from both end faces of the roll-type paper is longer than the facing distance between both side walls of the main body, each end of the erection core is a circular recess at the tip of both side walls facing each other. In order to put the roll type wrapping paper into the circular recess of one side wall with the erection core slanted, the core length is shortened by resisting the urging. It is necessary to make the length shorter than the gap and to fit it in the gap between both side walls in that state, and to insert the other end of the core into the circular recess of the other side wall, which is very troublesome to operate. In particular, if the length of the facing interval on both side walls of the main unit is slightly longer than the axial length of the roll-type wrapping paper, that is, when the roll-type wrapping paper is mounted horizontally, the facing surface of each side wall is rolled. If it is close to each end face of the wrapping paper, the end of the roll wrapping paper will come into contact with the side wall when the roll wrapping paper is slanted and placed in the space on both side walls together with the core, which makes the operation very difficult.

[0004]

[Means for Solving the Problems] Therefore, the present invention can easily roll a roll-type wrapping paper even if the length of the facing interval of both side walls of the main body is slightly longer than the axial length of the roll-type wrapping paper. Since it can be installed horizontally, it has an extendable and retractable roll-type paper roll installation core and two side walls facing each other. A roll-type paper wrapper holder comprising a holder body that supports the erection core, and a core having recesses formed by opening one end outside each side wall and closing the other end on opposite surfaces of both side walls of the holder. Introducing grooves are provided so as to face each other, and the bottom of at least one of the core introducing grooves is gradually shallowed from one end toward a recess at the other end.

[0005]

【Example】

 In the illustrated embodiment, 1 is a holder main body, 2 is its fixed substrate, and 3 and 4 are left and right side walls projecting from opposite sides of the substrate.

In the embodiment shown in FIGS. 1 to 4, at the tips of the surfaces of the left and right side walls 3 and 4 facing each other, a core introduction groove 5 having one end 5a opened and the other end closed is formed in the vertical direction. Are provided so as to face each other, and the other end of each groove is provided with recesses 6, 6 into which the respective end portions 10 ', 10' of the erection core 10 fall, and the bottoms 7 of both grooves 5, 5 are provided from one end. The depth is gradually reduced toward the depression 6. The recess 6 is slightly deeper than the shallowest part of the bottom 7 in front of the recess.

The erection core 10 is the same as that shown in the above-mentioned Japanese Utility Model Application Laid-Open No. 58-156496, and as shown in FIG. 4, a shaft portion 11 that is inserted into the center of the roll-type wrapping paper 20 and a shaft. A movable pin protruding from one end of the shaft portion 11 is pushed outward by a spring 14 also housed in a hollow portion 12 provided at one end of the shaft portion 11 and is similarly housed in the hollow portion. The movable pin 15 can be expanded and contracted by the movable pin 15 and is always extended by being pushed outward by the spring 14. The length L ₁ of the installed core 10 in the expanded state is slightly shorter than the length L ₂ between the deep upper end portions of the bottoms of the core introduction grooves 5 and 5 of the side walls 3 and 4 opposed to each other, but It is slightly longer than the length L ₃ between the shallow parts in the foreground.

Therefore, the shaft portion 11 of the erection core 10 is inserted through the central portion of the roll-type wrapping paper 20, and the end portion 10 ′ that is the tip of the movable pin 15 together with the roll-type wrapping paper and the end portion 10 at the other end of the shaft portion. 'Is fitted into the opposite core introduction grooves 5 and 5 (see the solid line in FIG. 4) and pushed downward. As a result, the movable pin 15 is gradually pulled into the hollow portion 12 against the bias of the spring 14 due to the inclination of the bottoms 7, 7, and the erection core 10 is lowered along with the roll-type wrapping paper along the core introduction grooves 5, 5. Upon reaching the depressions 6, 6 at the lower end of the groove, the movable pin 15 is pushed outward again by the spring 14, and the ends 10 ', 10' of the installation core snap into the depressions 6, 6. It is rotatably held and the roll-type wrapping paper is mounted horizontally between the side walls 3 and 4 together with the installation core (see the two-dot broken line in FIG. 4). In this way, when the roll-type wrapping paper is attached to the holder, and when the paper is used up, contrary to the above, a little force is applied to lift the erection core, and both ends of the erection core are removed from the recesses 6 and 6 to remove the erection core from the holder. , Reinstall a new roll paper. When the roll-type wrapping paper has a paper tube in the center, the erection core penetrates the inside of the paper tube, so remove the erection core from the holder as described above, but the roll-type wrapping paper does not have the paper tube in the center. In this case, since the erection core is exposed when the paper is used up, the shaft portion 11 is pushed in the axial direction toward the movable pin 15, the other end portion of the shaft portion is made to escape from the recess 6, and the direction is slanted. It can also be removed from the holder.

In the embodiment of FIGS. 1 to 4 described above, the bottoms 7, 7 of the core introducing grooves of the opposite side walls are gradually shallowed from the one end 5 a toward the recess 6, but as shown in the embodiment of FIG. It is one side wall, for example, the core introduction groove of 3, that makes the bottom 7 gradually shallower from one end 5a toward the recess 6, and the bottom of the core introduction groove of the other side wall 4 is set to a certain depth shallower than the recess 6. It is also possible to attach the roll-type wrapping paper between both side walls together with the erection core, and remove the erection core between the both side walls when the paper is used up.

In any of the embodiments, the core introduction groove 5 is not limited to be provided in the vertical direction (vertical) and one end is opened to the upper surface of the side walls 3 and 4, and may be provided in a direction inclined with respect to the vertical. . Further, since the holder main body 1 including the fixed substrate 2 and the left and right side walls 3 and 4 is integrally molded relatively thinly with plastic, the thick piece 8 having the core introduction groove 5 is formed separately from the main body. Then, this piece is fixed to both side walls of the main body by adhesion or the like, but of course, the core introducing groove 5 may be simultaneously formed on the opposing surfaces of the side walls 3 and 4 when the holder main body is molded. .

Further, as shown in the figure, the core introducing groove 5 has a groove width that is wide at one end 5 a and becomes gradually narrower toward the recess 6, so that both ends 10 ′ and 10 ′ of the erection core 10 are connected. It is easier to insert the lead into the grooves 5 and 5.

The erection core 10 is not limited to the one having the movable pin 15 shown in FIG. 4. For example, as shown in FIG. 6, the erection core 10 is molded into a hollow plastic, and is stretched by its own elasticity at both ends. It may be expandable / contractible and urged in the stretched state, such as one having the bellows tube portions 16 and 16 urged in the state.

[Effect of the device]

 As is clear from the above, according to the present invention, each end of the installation core projecting from both end surfaces of the roll-type paper is placed inside the opposite core introduction grooves on the left and right side walls of the holder body. The end of the erection core can be detachably held in the recess at the other end of the groove by simply inserting it into the outside of the side wall and pushing it in along the core introduction groove. It is extremely easy to install between the two.
