Description

  The present invention relates to a magnet bar that can be suitably used to fix a piece of paper or the like.

As a fixture for fixing a sheet-like adherent piece made of paper or the like to an adherent surface such as a steel wall surface on which a magnet can be adsorbed, a ring-like, disc-like, flat rectangular permanent magnet, An outer sheath of a covering member made of a synthetic resin material that covers the magnet while leaving the attracting surface side is widely put into practical use (for example, see Patent Document 1).

Further, as the fixing device, there is also a paper piece fixing device in which a plurality of concave portions are formed on one side surface of an elongated rod-shaped member made of a synthetic resin material at intervals in the length direction, and permanent magnets are respectively assembled to the plurality of concave portions. It has been proposed (see, for example, Patent Documents 2 and 3).

  However, in the fixtures described in Patent Documents 1 to 3, since the attracting surface of the permanent magnet is fixed, characters or designs are printed on the fixture, or sheets on which the characters or designs are printed are fixed. There are the following problems when using the side surface of the fixture as a display surface by pasting it on the side surface of the fixture. That is, at least the attracting surface of the permanent magnet cannot be used as a display surface, and the surface adjacent to the attracting surface can be used as a display surface, but it is difficult to ensure sufficient visibility. There may be. Therefore, normally, only the surface opposite to the suction surface of the fixture is used as a display surface, and there is a problem that effective display using the entire side surface of the fixture cannot be performed. For example, in a sales promotion product or the like, it is preferable to increase the advertisement area as much as possible. However, the fixtures described in Patent Documents 1 to 3 have a problem that the advertisement area cannot be sufficiently secured. Moreover, it had only the basic function of fixing the fixture to the mounting surface, and was less playful and lacking in fun.

  Therefore, as disclosed in Patent Document 4, the present applicant has proposed a magnet bar in which a permanent magnet is freely movably housed in a hollow elongated casing having a polygonal cross section and the side surface of the casing serves as a display surface. With this magnet bar, the entire outer surface of the casing can be used as a display surface, and the permanent magnet moves with a rattling noise in the casing, so that it only functions as a fixture for fixing paper pieces etc. In addition, a simple toy-like fun can be provided to the user.

  By the way, when fixing a piece of paper or the like to the adherend surface with a conventional magnet bar, hold the piece of paper with one hand, place the piece of paper at the appropriate place on the adherend surface, and hold the magnet bar with the other hand. By fixing the magnet bar to the adherend surface with a piece of paper in between, the piece of paper will be fixed to the adherend surface, and when removing the piece of paper from the adherend surface, hold the piece of paper with one hand While removing the magnet bar with the other hand, the piece of paper is removed from the adherend surface. That is, it is necessary to use both hands when fixing the paper piece to the adherend surface and when removing the paper piece from the adherend surface.

  The purpose of the present invention is not only to be able to easily remove a piece of paper from the adherend surface with one hand, but also to use the entire outer surface of the casing as a display surface, and not only to function as a fixture for fixing the piece of paper. It is to provide a magnetic bar with a simple toy-like fun.

  The magnet bar according to the present invention is a magnet bar that is magnetically detachably attached to the adherend surface, and is provided with a cylindrical casing, and a plurality of partition walls are provided in the middle part in the longitudinal direction of the casing, A plurality of accommodating portions are formed in the casing at intervals in the length direction, and a permanent magnet is movably housed in the accommodating portion so that the magnetic pole side can face the adherend surface.

When attaching a piece of paper, etc., to the adherend surface, such as a steel wall, with this magnetic bar, hold the piece of paper, etc. with one hand, and place the piece of paper, etc. By holding the magnet bar and placing the magnet bar on the adherend surface with a piece of paper in between, the magnet bar and the piece of paper are attracted and held on the adherend surface by the magnetic attraction force of the permanent magnet built in the magnet bar. It will be. At this time, the permanent magnet moves so that the magnetic pole side having a strong magnetic attraction force faces the adherend surface in the housing portion of the casing, and the magnet bar and the paper piece are attracted and held on the adherend surface. Sufficient magnetic attractive force can be secured while using. For this reason, in the present invention, a cylindrical casing that is easy to roll is used as the casing of the magnet bar. However, the strong magnetic attraction force prevents the magnet bar from rolling downward with respect to the vertical adherend surface. Thus, the magnet bar can be attracted and held at a desired position. On the other hand, when removing a piece of paper attached to the adherend surface, the end of the piece of paper is held with one hand and the end of the piece of paper is pulled forward or diagonally upward so that the magnet bar is attached to the adherend surface. Since it rotates and moves out of the sheet while being held by suction, it is possible to remove a piece of paper with one hand.

In addition, since this magnet bar uses a cylindrical casing, the outer peripheral surface can be printed or engraved with characters or designs on the entire outer peripheral surface of the casing, or a sheet printed with characters or designs can be attached to the outer peripheral surface. The entirety can be used as a display surface. In addition, if the magnet bar is shaken by hand or the magnet bar rolls on the adherend surface, the permanent magnet will move with a rattling noise in the casing. Not only functions as a fixture, but also has a simple toy-like fun.

  Here, it is a preferred embodiment that the casing is constituted by two divided bodies that are divided into two in the circumferential direction. By comprising in this way, a permanent magnet can be loaded in the accommodating part of a casing in the state which divided | segmented the casing. In particular, when the casing is constituted by two divided bodies that are divided into two by a dividing plane passing through the center line, the two divided bodies can be configured so as not to form an undercut or the like, so that the moldability of the divided body can be improved. .

The magnet bar assembling method according to the present invention is the magnet bar assembling method according to claim 2 or 3, wherein the one split body is installed on the adherend surface, and the one split body housing portion is provided. The permanent magnets are sequentially loaded, the loaded permanent magnets are attracted to the adherend surface, and then one divided body is combined with the other divided body.

  Since the magnet bar according to the present invention has a cylindrical shape, when the magnet bar is magnetically attracted to the vertically attached surface, the magnet bar has a characteristic that it is easy to roll downward. It is necessary to use a permanent magnet having a stronger magnetic force than when using. However, when such a permanent magnet having a strong magnetic force is used, when the permanent magnet is loaded in the housing portion, the adjacent permanent magnets are attracted to each other, and it takes time to separate the permanent magnet. There is a problem that the loading operation becomes complicated. Therefore, in the assembling method of the present invention, the permanent magnets are sequentially loaded in the housing part in a state where the divided body of the casing is installed on the adherend, so that the permanent magnet loaded in the housing part is attracted to the adherend. Therefore, the problem that the permanent magnet is caught with the permanent magnet accommodated in the adjacent accommodating portion can be surely prevented, and the operation of loading the permanent magnet into the casing is efficiently performed by a simple method. It becomes possible. This assembling method can also be applied to the case where a permanent magnet is loaded into a rectangular tubular casing.

  According to the magnet bar of the present invention, it is necessary to use both hands when attaching a piece of paper to the adherend surface, but when removing the piece of paper from the adherend surface, it can be easily removed with one hand. Therefore, the operability of attaching / detaching a piece of paper or the like can be improved. In addition, with this magnet bar, the entire outer peripheral surface can be used as a display surface by printing or engraving characters or designs on the entire outer peripheral surface of the casing, or by sticking a sheet printed with characters or designs. It becomes. Furthermore, if the magnet bar is shaken by hand or the magnet bar rolls on the adherend surface, the permanent magnet will move with a rattling noise in the casing. Not only functions as a fixture, but also has a simple toy-like fun.

  In the method of assembling the magnet bar according to the present invention, the permanent magnets are sequentially loaded into the housing part in a state where the divided body of the casing is installed on the adherend, so that the permanent magnet loaded in the housing part is attracted to the adherend. Therefore, the problem that the permanent magnet is caught with the permanent magnet accommodated in the adjacent accommodating portion can be surely prevented, and the loading operation of the permanent magnet into the casing can be efficiently performed by a simple method. Can be performed.

Illustration of magnet bar usage Disassembled perspective view of magnet bar III-III sectional view of FIG.

Embodiments of the present invention will be described below with reference to the drawings.
As shown in FIG. 1 to FIG. 3, the magnet bar 1 includes a cylindrical hollow elongated casing 2 and a plurality of magnets 3 made of permanent magnets that are freely mounted in the casing 2. This is for fixing the adherend piece 5 such as a piece of paper to the adherend surface 4 made of a ferromagnetic material such as iron.

  The casing 2 is made of a synthetic resin material or a metal material to which the magnet 3 is not adsorbed, and is made up of two semi-cylindrical divided bodies 10A and 10B divided by a dividing surface passing through the center line. A fitting projection 11 is formed on both sides of one divided body 10A, and a fitting recess 12 that can be fitted to the fitting projection 11 is formed on both sides of the other divided body 10B. 10A is assembled in a cylindrical shape by fitting the fitting protrusion 11 into the fitting recess 12. However, it can be assembled into a cylindrical shape using an adhesive or the like, or can be assembled into a cylindrical shape using a screw or other fixture. Moreover, if the casing 2 is divided and configured so that the magnet 3 can be housed in the housing portion 14, the casing 2 can be divided and configured in an arbitrary range and an arbitrary number in the circumferential direction.

  A plurality of partition walls 13 are provided in the middle of the casing 2 in the length direction, and a plurality of storage portions 14 capable of freely storing the magnets 3 in the casing 2 by the plurality of partition walls 13 are spaced in the length direction. It is formed with a gap. Specifically, as shown in FIG. 2, two sets of two adjacent partition walls 13 are provided at an interval, and the inside of the casing 2 is divided into seven spaces by the six partition walls 13. Is accommodated in a housing part 14 formed by a set of two partition walls 13 so as to be freely movable. In this embodiment, three sets of two partition walls 13 are provided for the purpose of loading three magnets 3 in one magnet bar 1, but the number of partition walls 13 is the number of magnets 3 housed in the casing 2. It can be set appropriately depending on the situation.

  The partition wall 13 of the other divided body 10B can be omitted by providing a disk-shaped partition wall on the one divided body 10A, for example. In addition, the partition wall 13 is preferably formed in a plate shape in order to ensure the floating stability of the magnet 3, but it can also be formed in one or more rod shapes. Furthermore, instead of the partition wall 13, a block-like or box-like partition member made of a separate member can be internally fixed in the casing 2, and a housing part 14 for housing the magnet 3 can be formed in the casing 2. is there.

  As the magnet 3, a permanent magnet made of any material such as an alnico magnet, a ferrite magnet, an iron / chromium / cobalt magnet, a manganese / aluminum / carbon magnet, a rare earth magnet, and a bonded magnet can be employed. Further, in the present embodiment, the magnet 3 is formed in a columnar shape as shown in FIG. 2, but may be formed in a polygonal column shape such as a cube or a rectangular parallelepiped. It is also possible to configure one magnet 3 by combining a plurality of small permanent magnets. The number of magnets 3 can be set to an arbitrary number according to the size, thickness, etc. of the adherend piece 5 to be fixed.

  The magnet 3 floats in the accommodating portion 14 so that the S pole 3s and the N pole 3n of the magnet 3 are orthogonal to the longitudinal direction of the casing 2, that is, the S pole 3s or the N pole 3n can face the adherend surface 4. It is freely decorated. However, when the magnetic force of the magnet 3 is strong, the S pole 3 s and the N pole 3 n are installed in the housing portion 14 so as to be arranged on both sides of the casing 2 in the longitudinal direction, and the magnetic attractive force around the casing 2 in the longitudinal direction. Can be configured to be set uniformly.

  A display surface is formed on the outer peripheral surface of the casing 2 by directly printing or stamping characters, pictures, and the like. However, a display surface can be formed by sticking a sheet or film on which characters or designs are printed to the casing 2, or a character or design can be printed on a film that shrinks when heated to form a cylinder. It is also possible to provide a display surface on which characters and patterns are formed by thermally shrinking the film in a state of being packaged on the casing 2 and integrally packaging the film on the casing 2. The characters and patterns to be printed or stamped can be arbitrarily set according to the purpose of use of the magnetic bar 1, for example, when used as a promotional product, a display screen on which a product advertisement is printed or stamped is provided. In the case of using as a stationery, a display surface on which characters or characters of various animations are printed or stamped can be provided. Moreover, it is also possible to utilize the both end surfaces of the longitudinal direction of the casing 2 as a display surface.

  In this magnet bar 1, the attachment piece 5 and the magnet bar 1 are attached to the attachment surface 4 so that the sheet-like attachment piece 5 made of paper or the like is sandwiched between the attachment surface 4 and the magnet bar 1. The magnet 3 housed in the magnet bar 1 moves toward the adherend surface 4 in the casing 2 by the magnetic attraction force, and the magnet bar 1 and the adherend piece 5 are attracted to the adherend surface 4 by the magnetic attraction force of the magnet 3. Thus, the adherend piece 5 is fixed to the adherend surface 4.

  Specifically, when a piece of paper or the like is attached to the adherend surface 4 such as a steel wall by the magnet bar 1, the piece of paper or the like is held at an appropriate position on the adherend surface 4 by holding the piece of paper with one hand. The magnet bar 1 is held on the adherend surface 4 by holding the magnet bar 1 with the other hand in a state in which the attachment piece 5 is arranged, and sandwiching the attachment piece 5 such as a piece of paper. The magnet bar 1 and the adherend piece 5 are attracted and held on the adherend surface 4 by the magnetic attraction force of the magnet 3 installed therein. On the other hand, when removing the adherend piece 5 such as a piece of paper attached to the adherend surface 4, the end of the adherend piece 5 of the paper piece is held with one hand, and is indicated by an imaginary line and an arrow A in FIG. In this way, by pulling the end of the adherend piece 5 forward or obliquely upward, the magnet bar 1 is attracted and held on the adherend surface 4 as shown by the phantom line and the arrow B, and is moved out of the adherend piece 5. Since it rotates, the adherend piece 5 can be removed with one hand. Thus, when attaching the adherend piece 5 to the adherend surface 4, it is necessary to use both hands, but when removing the adherend piece 5 from the adherend surface 4, it can be easily removed with one hand. Therefore, the detachability operability of the adherend piece 5 can be improved.

  Further, in a state where the magnet bar 1 is attracted to the adherend surface 4, the magnet 3 moves so that the S pole 3 s and the N pole 3 n having the strongest magnetic attraction force face the adherend surface 4 in the accommodating portion 14. Thus, it is attracted and held on the adherend surface 4, so that a sufficient magnetic attraction force can be secured while using the small magnet 3. For this reason, in this invention, although the cylindrical casing 2 which is easy to roll is used as the casing 2 of the magnet bar 1, it is strong that the magnet bar 1 rolls downward with respect to the vertical adherend surface 4. Thus, the magnetic bar 1 can be reliably prevented and held at a desired position by the magnetic attraction force.

  Furthermore, since this magnet bar 1 uses a cylindrical casing 2, a character or a pattern is printed or engraved on the entire outer peripheral surface of the casing 2, or a sheet on which a character or a pattern is printed is pasted. The entire outer peripheral surface can be used as the display surface. Further, when the magnet bar 1 is shaken by hand or the magnet bar 1 rolls on the adherend surface 4, the permanent magnet moves with a rattling noise in the casing 2, so that the magnet bar 1 In addition to the function as a fixing tool for fixing, etc., it becomes an interesting thing like a simple toy.

  When the magnet bar 1 is assembled, the magnets 3 are sequentially loaded into the accommodating portion 14 of the one divided body 10A in a state where the one divided body 10A is installed on a surface to be attached such as a horizontally positioned iron plate. It is preferable that the loaded magnet 3 is attracted to the adherend surface and then assembled by combining one divided body 10A with the other divided body 10B. Thus, since the magnet 3 loaded in the accommodating part 14 is attracted to the adherend, when the magnet 3 is loaded in the adjacent accommodating part 14, the magnet 3 previously loaded in the accommodating part 14. Can be reliably prevented, and the loading operation of the magnet 3 into the casing 2 can be efficiently performed by a simple method.
