Description

[Technical Field]

[0001] The present invention relates to a roll holder for holding a roll. [Background technology]

[0002] Patent Document 1 discloses a paper holder in which roll paper such as kitchen paper is supported on support shafts at the tips of swinging parts provided on the left and right sides.

[0003] In addition, the paper holder in Patent Document 1 has a resistance portion located on the back of the roll paper, which provides resistance against rotation, so that the roll paper can be cut along the perforations by pulling the roll paper horizontally after it has been pulled out to the desired length. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2024-644 Summary of the Invention [Problem to be solved by the invention]

[0005] In addition, kitchen paper rolls are sold in a wide variety of widths, with foreign-made rolls in particular tending to be wider, and users can select the appropriate roll depending on their intended use.

[0006] However, the paper holder of Patent Document 1 can only accommodate roll paper of a specific width range due to the arrangement of the left and right support shafts.

[0007] Furthermore, with the paper holder of Patent Document 1, when the amount of roll paper decreases, the resistance force applied to the resistance part by the weight of the paper holder decreases, and there is also the problem that sufficient resistance force cannot be obtained when cutting the roll paper.

[0008] SUMMARY OF THE INVENTION An object of the present invention is to provide a roll holder that solves the above-mentioned problems and allows rolls of various widths to be attached. [Means for solving the problem]

[0009] In order to achieve the above-mentioned object, the roll body holder of the present invention comprises a planar base portion, a pillar portion extending perpendicular to the surface of the base portion, and a roll body locking portion provided at the tip of the pillar portion, and holds the roll body by inserting the core tube portion of the roll body into the pillar portion, and the roll body locking portion consists of a cylindrical main body portion and one or more tongue portions arranged radially from the side of the main body portion, and the tongue portions are molded from a thin-walled elastic body, and the diameter of the main body portion in a cross section perpendicular to the central axis of the pillar portion is smaller than the diameter of the core tube portion, and the diameter of the circumscribing circle of the tongue portions in a cross section perpendicular to the central axis of the pillar portion is larger than the diameter of the core tube portion. [Effects of the Invention]

[0010] In this way, the roll body holder of the present invention makes it possible to attach roll bodies of various widths, and regardless of the remaining amount of sheet material wound on the roll body, the sheet material pulled out to the desired size from the roll body can be easily separated by pulling it laterally toward the substrate portion. [Brief explanation of the drawings]

[Figure 3] 3 is an explanatory diagram of a cross section of the roll body holder taken along line AA' in FIG. 2. FIG. [Figure 4] FIG. 10 is a perspective view of the roll body holder with the roll material pulled out. [Figure 5] FIG. 10 is a perspective view of a roll body holder according to a second embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0012] The present invention will be described in detail below based on the illustrated embodiments. [Example]

[0013] FIG. 1 is a perspective view of the roll body holder, FIG. 2 is a perspective view of the roll body holder with a roll body attached, FIG. 3 is an explanatory diagram of a cross section along line A-A' in FIG. 2, and FIG. 4 is a perspective view of the roll body holder with the roll material pulled out.

[0014] The roll holder holds a roll R around which a sheet material such as kitchen paper is wound so that it can be pulled out, and the roll R has a sheet material R1, such as paper kitchen paper, wound around a hollow cylindrical core tube R2. Perforations (not shown) are formed in the sheet material R1, and when cutting the sheet material R1 to a predetermined size, it is cut along the perforations.

[0015] The roll body holder is composed of a flat base portion 1, such as a rectangle, a pillar portion 2 extending perpendicular to the surface 1a of the base portion 1, a roll body locking portion 3 provided at the tip of the pillar portion 2, and a support body 4 extending approximately parallel to the pillar portion 2 relative to the surface 1a of the base portion 1.

[0016] Although the pillar portion 2 is a cylindrical body in the first embodiment, a pillar portion of any suitable shape such as a regular polygonal pillar may also be used. Furthermore, the pillar portion 2 may have a hollowed-out shape as shown in Fig. 1 to reduce the amount of material used, as long as the strength can be maintained.

[0017] The base 2a on the base side of the pillar 2 is fixed to the base plate 1, and the roll body locking part 3 is rotatably held by a bearing 2b provided in the pillar 2 via a shaft 3b provided along the central axis of the main body 3a. Note that the rotation structure formed by the shaft 3b of the roll body locking part 3 and the bearing 2b of the pillar 2 may alternatively be a rotation structure in which a bearing is provided for the roll body locking part 3 and a shaft is provided on the pillar 2.

[0018] Alternatively, a structure may be adopted in which a rotatable shaft portion or bearing portion is provided on the base portion 2a of the column portion 2, and a bearing portion or shaft portion that engages with this shaft portion or bearing portion is provided on the base portion 1. In such a case, it is not necessary to make the roll body locking portion 3 rotatable relative to the column portion 2.

[0019] Additionally, a sheet-like friction material 1b is attached to the surface 1a of the base plate 1 so as to surround the base 2a of the column 2. This friction material 1b is made of a material with high frictional force and elasticity, such as silicone rubber.

[0020] The roll body locking portion 3 is composed of a main body portion 3a located in the center, an axial body portion 3b arranged along the central axis of this main body portion 3a, and multiple tongue portions 3d arranged radially outward from the outer surface 3c of the main body portion 3a.

[0021] These tongue portions 3d are molded from a thin elastic body made of synthetic resin, such as silicone rubber, etc. Although three tongue portions 3d are arranged at equal intervals along the outer periphery as shown in Fig. 1, a single elastic piece that covers the entire periphery of the outer periphery 3c may also be used as the tongue portion 3d.

[0022] The diameter d1 of the circumscribing circle of the cross-sectional shape of the main body portion 3b in a cross section perpendicular to the central axis of the column portion 2, i.e., the diameter d1 of the cross-sectional circle of the cylindrical main body portion 3b in Figure 1, is smaller than the diameter d2 of the core tube portion R2 of the roll body R, and the diameter d3 of the circumscribing circle of the tongue portion 3d in a cross section perpendicular to the central axis of the column portion 2 is larger than the diameter d2 of the core tube portion R2.

[0023] The support 4 is made of a flat metal plate bent at necessary locations, and extends parallel to the column 2 from the base 1c attached to the surface 1a of the substrate 1. At the tip 4a of this support 4, a fixed portion 4b is bent upward in a U-shape.

[0024] A disk-shaped contact portion 4c with an elastic body attached to its upper surface is disposed between the tip portion 4a and the fixed portion 4b, and this contact portion 4c is fixed to the upper end of a threaded rod 4d that is screwed into the tip portion 4a, and a disk-shaped fastening portion 4e is fixed to the lower end of the threaded rod 4d on the underside of the tip portion 4a. In addition, an elastic buffer body 1d made of a foam material or the like is attached near the side of the base portion 1c of the substrate portion 1.

[0025] 3, the base end of the support 4 passes through the base portion 1c and the substrate portion 1 and extends to near the center of the base portion 2a of the pillar portion 2. In this way, by providing the support 4 as a core material for the base portion 1c, the substrate portion 1, and the base portion 2a of the pillar portion 2, the roll body holder is reinforced.

[0026] In use, the roll holder is fixed to a shelf material S, such as a kitchen cupboard, as shown by the dotted line in Figure 3. When the shelf material S is positioned between the fixing part 4b and the contact part 4c and the tightening part 4e is rotated, the contact part 4c rises via the threaded rod 4d, and the shelf material S can be clamped and fixed between the fixing part 4b and the contact part 4c.

[0027] Furthermore, since the buffer body 1d also abuts against the underside of the shelf material S, the roll body holder is fixed to the shelf material S without wobbling. Also, since the abutment portion 4c and the buffer body 1d abut against the underside of the shelf material S, the underside of the shelf material S will not be damaged.

[0028] To attach the roll R to the roll holder, the core tube portion R2 of the roll R is fully pushed into the column portion 2 of the roll holder. By attaching the roll R in this manner, the tongue portion 3d of the roll locking portion 3 is narrowed and elastically abuts against the inner wall of the core tube portion R2 at some position of the core tube portion R2. The tongue portion 3d elastically contacts the core tube portion R2, the roll locking portion 3 locks the core tube portion R2, and the roll locking portion 3 and the roll R become one unit.

[0029] In this way, the roll body locking portion 3 is locked at an intermediate position within the core tube portion R2, so that the roll body locking portion 3 can lock the roll body R regardless of the length of the core tube portion R2, i.e., the width of the roll body R.

[0030] After pulling out an arbitrary length of the sheet material R1 of the roll body R downward from the roll body holder shown in FIG. 2 to the state shown in FIG. 4, when the sheet material R1 is pulled in the direction B parallel to the central axis of the pillar portion 2, the end R3 of the roll body R comes into contact with the friction material 1b.

[0031] When the end R3 of the roll R comes into contact with the friction material 1b in this manner, the rotation of the roll R is restricted by the friction material 1b, and the pulled-out roll R is cut at the perforations M. [Example]

[0032] FIG. 5 is a perspective view of a roll body holder according to the second embodiment, and this roll body holder is used by being placed on a table, for example.

[0033] The configurations of the base portion 1, the column portion 2, and the roll body locking portion 3 are almost the same as those in Example 1. Instead of the support 4 that can be fixed to the shelf material S in Example 1, a support 4' serving as a grippable handle portion extends perpendicularly upward from the surface 1a of the base portion 1.

[0034] By attaching the roll body R to the column portion 2 and holding and supporting the support body 4' of the roll body holder placed on the table with, for example, the left hand, it is possible to easily cut the pulled-out roll body R with the right hand, in the same way as with the roll body holder of Example 1.

[0035] Furthermore, although the supports 4, 4' are provided in the roll holders of Examples 1 and 2, these are not necessarily provided. If the supports 4, 4' are not provided, the substrate 1 is fixed to a wall surface or the like with screws, suction cups, or the like, and the sheet material R1 unwound from the roll R to a desired length is pulled toward the substrate 1 and separated.

[0036] In this way, the roll body holder of the present invention makes it possible to attach roll bodies R of various widths, and regardless of the remaining amount of sheet material R1 wound around the roll body R, the sheet material R1 pulled out to the desired size from the roll body R can be easily separated by pulling it laterally toward the substrate portion 1.
