JP-A-2005-305706

  By the way, since the above-mentioned conventional stationery holder needs to stick the flexible plate with which the convex part was provided in the inner surface of the cylindrical insertion part, a structure becomes complicated and cannot be manufactured easily. There is a problem. In addition, the small-diameter marker pen has a problem that it cannot be held stably because it cannot sufficiently press-contact the convex portion.

  The present invention has been made in view of the background as described above, and provides a stationery holder that has a simple configuration, can hold a large and small bar-shaped stationery, and can be easily manufactured. For the purpose.

  In order to achieve the above-described object, a stationery holder according to the present invention is a stationery holder for fixing a rod-shaped stationery including a marker pen and an indicating tool to a writing board capable of attracting a magnet, and a cylinder holding the rod-shaped stationery. A cylindrical portion of the holding portion is formed in a substantially C-shaped cross section in which a cut is provided over the entire length in the axial direction, and a holding portion having a shape portion and a magnet provided integrally with the holding portion. The rod-shaped stationery is expanded by insertion of the rod-shaped stationery, and is configured to hold the rod-shaped stationery by an elastic force by the expansion.

  According to the stationery holder configured in this way, the cylindrical portion of the holding portion is formed in a substantially C shape with a cut across the entire length in the axial direction, and is expanded by insertion of the rod-shaped stationery. Since the rod-shaped stationery is held by the elastic force generated by the above, the configuration is simple, the rod-shaped stationery can be held in various sizes, and can be easily manufactured.

  Moreover, the said cylindrical part is good also as a shape crushed in the radial direction which passes the said cut | interruption. According to this, it becomes possible to hold | maintain the bar-shaped stationery of a wider size with the stationery holder of one size. Specifically, it can correspond to a small-sized bar-shaped stationery in the radial direction passing through the cut, and can correspond to a large-sized bar-shaped stationery in the radial direction substantially orthogonal to the radial direction passing through the cut.

  A plurality of protrusions extending in the axial direction may be provided on the inner surface of the cylindrical portion. According to this, since the force which holds a rod-shaped stationery concentrates on a protrusion part, a rod-shaped stationery can be hold | maintained reliably. Moreover, since the contact area of a cylindrical part and a rod-shaped stationery becomes small and it extends in an axial direction, insertion and extraction of a rod-shaped stationery can be performed easily.

  It is desirable that the ridges are provided at least at both edges that form the cut. Since both edge portions forming the cut are portions where the elastic force (the force for holding the rod-like stationery) due to the expansion is particularly strong, the rod-like stationery can be more reliably held by providing the protrusions at this portion. Moreover, since a protrusion part protrudes toward the inner side of a cylindrical part, it can hold | maintain a small-sized rod-shaped stationery.

  According to the stationery holder of the present invention, the cylindrical portion of the holding portion is formed in a substantially C-shaped cross section in which a cut is provided over the entire length in the axial direction, and is expanded by insertion of the rod-shaped stationery, and the elastic force due to the expansion Since the rod-shaped stationery is held by the above, the configuration is simple, the rod-shaped stationery having a wide and small size can be held, and can be easily manufactured.

  The magnet holding part 5 is formed in a substantially square cylindrical shape in plan view, and is provided so as to protrude outward from a position on the back side of the protrusion 43 on the outer surface of the cylindrical part 4. A pair of protrusions 51 extending in the vertical direction in FIG. 2 are provided on the inner surface of the magnet holding portion 5 so as to face each other in the radial direction passing through the slit 41.

  The magnet 3 is a rectangular parallelepiped permanent magnet, and is provided integrally with the holding unit 2 by being inserted into the magnet holding unit 5. The magnet 3 is prevented from coming out of the magnet holding portion 5 by being sandwiched between a pair of protrusions 51 provided on the inner surface of the magnet holding portion 5. The magnet 3 may be simply inserted into the magnet holding part 5 or may be inserted after an adhesive is applied to the inner surface of the magnet holding part 5.

The effects of the stationery holder 1 according to the present embodiment configured as described above will be described.
When the rod-like stationery P is inserted into the stationery holder 1, the tubular portion 4 is expanded in a direction in which both edge portions 4A are separated. If it does so, since the cylindrical part 4 will return to the original shape (state which does not hold | maintain the rod-shaped stationery P), the rod-shaped stationery P is hold | maintained by the restoring force at that time (elastic force by expansion).

  The stationery holder 1 of this embodiment includes a cylindrical portion 4 formed in a substantially C shape provided with a slit 41 over the entire length in the axial direction, and a magnet holder that is formed integrally with the cylindrical portion 4 and into which the magnet 3 is inserted. Since the portion 5 is provided, the configuration of the rod-shaped stationery P having a wide and small size can be held by expanding the cylindrical portion 4 while the configuration is simple, and the rod-shaped stationery P can be fixed to the writing board B. Moreover, since the structure is simple, it can be easily manufactured by forming the holding portion 2 by, for example, injection molding and inserting the magnet 3 into the magnet holding portion 5.

Since the stationery holder 1 has a shape in which the tubular portion 4 is crushed in the radial direction passing through the slit 41, the single stationery holder 1 can hold a wide variety of bar-shaped stationery P. Specifically, as shown in FIG. 5 (a), since the length of the short axis direction is small, it can be held in a small bar-like stationery P _S moiety dimensions smaller sizes. In this embodiment in particular, it is possible to reliably hold the smaller rod-like stationery P _S Size Since protrusions 42 protruding from both edge portions 4A inwardly is provided.

Further, as shown in FIG. 5 (b), by the tubular portion 4 is increased expansion can hold a large rod-like stationery P _L size. In the present embodiment, since the dimension of the long axis direction is larger than when the tubular portion 4 is formed in a cylindrical shape, it is possible to hold a large rod-like stationery P _L of further size .

  Since the stationery holder 1 is provided with the ridge portions 42 and 43 on the inner surface of the tubular portion 4, the force to hold the rod-like stationery P concentrates on the ridge portions 42 and 43, so that the rod-like stationery P can be securely attached. Can be held in. In particular, in the present embodiment, since the protruding portion 42 is provided on both edge portions 4A where the elastic force due to the expansion is particularly strong, the rod-shaped stationery P can be held more reliably.

  Further, the contact area between the tubular portion 4 and the rod-shaped stationery P is reduced by the protrusions 42 and 43, and the protrusions 42 and 43 continuously extend along the axial direction. Insertion and extraction can be performed easily.

For example, as shown in FIG. 7A, the slit 41A may be provided in a straight line so as to be inclined with respect to the axial direction. As shown in FIG. It is good also as a structure provided so that the shape which meanders along an axial direction may be drawn.

  In the above-described embodiment, the configuration in which a total of three protrusions 42 and 43 extending in the axial direction are provided on the inner surface of the tubular part 4 is not limited to this. For example, the protrusions are Two (see FIG. 6B) or four or more may be provided. Moreover, it is good also as a structure which does not provide a protrusion part (refer FIG. 7).

  In the said embodiment, although the stationery holder 1 (cylindrical part 4) showed the structure which fixes the rod-shaped stationery P to the writing board B by hold | maintaining the rod-shaped stationery P directly, this invention is not limited to this. Absent. For example, the stationery holder 1 </ b> A shown in FIG. 8 includes an auxiliary holder 7 in addition to the holder 2 and the magnet 3.

  The auxiliary holder 7 is made of resin, metal, or the like, and includes a held portion 8 that is inserted into the tubular portion 4 and a pair of holding arms 9 that hold a stationery or the like.

  The held portion 8 is formed in a shape (substantially elliptical cylindrical shape) along the inner peripheral surface of the cylindrical portion 4, and a portion corresponding to the slit 41 has a cut across the entire length in the axial direction (vertical direction in FIG. 8). It is formed in a substantially C shape in plan view. In the form shown in FIG. 8, the length of the held portion 8 in the axial direction is shorter than the length of the tubular portion 4, but is not limited to this, and the length is the same as that of the tubular portion 4.
