Description

[Technical field]

[0001] The present invention relates to scissors using magnets.

[0002] When cutting an object with scissors, you place your fingers through the finger holes in the handle of the scissors, apply force in the direction that opens the scissors blades, and then the scissors open. The scissors then come into contact with the object, and you apply force to the fingers in the direction that closes the scissors blades. Because the cutting action of scissors requires force, it can be a burden for agricultural workers who use them for fruit harvesting and other repeated cutting operations.

[0003] For the above reasons, scissors that utilize magnetic force have been proposed to reduce the burden. The prior art described in Patent Document 1 reduces the burden by using the attractive or repulsive force of a magnet, and also discloses how to attach and detach the magnet. However, in Patent Document 1, the magnet can be attached to the case by engaging the convex part of the magnet with the concave part of the case, and the magnet is removed by pulling it out of the opening of the case to release the engagement between the magnet and the case, so the disengagement is not necessarily easy. In other words, it is premised on removing the magnet that is engaged with the case by the convex and concave parts, and the magnet cannot be easily removed. In particular, some agricultural workers prefer scissors that open by the repulsive force of a magnet, but there is a demand for easy replacement of the magnet to obtain the repulsive force according to one's preference.

[0004] [Patent Document 1] Patent No. 5420468 Summary of the Invention

[0005] In view of the problems with the invention of Patent Document 1, the present invention aims to provide scissors with magnets that use the magnetic force of magnets placed in the handle to assist opening and closing operations, and in which the magnets have a simple structure and can be easily replaced. [Means for solving the problem]

[0006] Therefore, the scissors of the present invention are characterized in that they comprise a pair of handle bodies, a pair of blade bodies inserted and fixed into the handle bodies, and the blade bodies are axially supported so that they can be rotated at an intersecting position, and in that they have magnet storage sections for storing magnets in opposing positions when the handle bodies are closed, and have a guide port that opens into the handle bodies and communicates with the magnet storage sections.

[0007] It is also preferable that the magnet storage section has an attraction section for attracting, storing and holding the magnet therein and a hollow section, and that the hollow section has a communication passage communicating with the guide port.

[0008] It is also preferable that the blade body has a cutting blade portion and a handle insertion portion that is inserted into the handle body, and that the attraction portion is an exposed portion of the blade body where the portion inserted into the handle body is exposed within the magnet storage portion.

[0009] It is also preferable that the magnet housing portion has a protruding edge extending upright around the periphery thereof. Effect of the Invention

[0010] According to the invention described in claim 1, by providing magnet housings at positions facing each other in the closed state, it is possible to assist the opening action of the scissors by the repulsive force of the magnets, and it is also possible to assist the closing action by utilizing the magnetic attraction action. In order to appropriately change this induction action or to change the strength of the magnetic force to one's liking, it is possible to easily remove and replace the magnets by inserting a rod-shaped tool such as an awl into a guide hole that communicates with the magnet housings.

[0011] According to the invention described in claim 2, by dividing the magnet storage section into an adsorption section and a hollow section and connecting the communication passage from the guide port to the hollow section, not only can the magnet be stored and held in the magnet storage section with a simple configuration, but also, since the rod-shaped instrument is connected from the guide port to the hollow section, it can be easily pulled out from the back side of the magnet with the rod-shaped instrument. This makes it easy to hold and pull out the magnet with a simple configuration. It is also possible to easily remove the magnet by inserting the rod-shaped instrument so that it reaches the back side of the magnet.

[0012] According to the invention described in claim 3, by making the attraction part the exposed part of the blade, the blade can be used to attract and hold the magnet, and the magnet can be housed and held in the magnet housing part with a simple structure.

[0013] According to the invention described in claim 4, a protruding edge is formed in the magnet accommodating section, which not only makes it possible to easily guide the magnet into the magnet accommodating section when attaching it to the magnet, but also prevents the two magnets from coming into contact and being damaged when the scissors are opened and closed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] An embodiment of the magnetic scissors of the present invention will be described in detail with reference to the drawings. Note that the following description is of one embodiment, and the present invention is not limited thereto.

[0016] As shown in Fig. 1, scissors 1 comprises a pair of handles 2, 2, a pair of blades 3, 3 which are fixed by inserting blade insertion sections 32 into the handles 2, 2, and the blades 3, 3 are supported by shafts X so as to be rotatable at their intersecting positions. When the handles 2, 2 are closed, a pair of magnet storage sections 40, 40 for storing magnets A are provided at opposing positions, and a guide opening 45 (see Figs. 2 and 3) is provided adjacent to the pair of magnet storage sections 40, 40 and communicating with the inside. A tool for removing magnets A can be inserted through the guide opening 45.

[0017] As shown in Fig. 2, the handle 2 is a resin cover member that includes a hollow blade housing section 21 that is open at one longitudinal end and closed at the other end, and an engagement section 23 that protrudes inward from the open end 22 of the blade housing section 21 and engages with an engagement step section 34 of the blade 3, to which the blade 3 is attached. The open end 22 may be shaped to incline in either direction. The handle 2 has a finger hook 24 that extends in a generally circular or elliptical shape from the blade housing section 21 to one side, and the magnetic scissors 1 can be opened and closed by the user putting their fingers through the finger hook 24 and applying force to the outside and inside.

[0018] The blade bodies 3, 3 are slender, sharp, metallic, magnetic members, and comprise blade sections 31, 31 with a sharpened tip, and handle insertion sections 32, 32 that are inserted and fixed into the handle bodies 2, 2, with a connecting hole 33 for pivotal support formed in the center between the blade sections 31, 31 and the handle insertion sections 32, 32, and the pair of blade bodies 3, 3 are pivotally supported by a connecting device G such as a screw in the connecting hole 33, so that each blade body 3, 3 can be opened and closed. This makes it possible to cut an object to be cut.

[0019] The concave magnet storage sections 40, 40 of the scissors 1 will be described. As shown in Fig. 2 to Fig. 5, the magnet storage sections 40, 40 are recessed from the opposing surfaces (inner surfaces) 2a, 2a of the handle bodies 2, 2 into a box-like, approximately trapezoidal shape. The magnet storage sections 40, 40 are formed with protruding edges 41, 41 that protrude from the opposing surfaces 2a, 2a of the handle bodies 2, 2 toward the opposing handle bodies 2, 2, and are formed so that the portions surrounded by the protruding edges 41, 41 are recessed. The protruding edges 41, 41 not only prevent the magnets A, A from coming into direct contact and being damaged during the closing operation of the scissors, but also function as guides when inserting the magnets A, A into the magnet storage sections 40, 40, making the insertion easier.

[0020] The magnet storage parts 40, 40 have a magnet storage space 42 for storing the magnet A on the front side, and an adhesion part 43, 43 and a hollow part 44, 44 on the back side and bottom side of the magnet storage space 42 (see Figs. 4 and 5). The adhesion part 43, 43 attracts the magnet and maintains the storage state of the magnet A stored in the magnet storage space 42, and the adhesion part 43, 43 in this embodiment is the blade body exposed part 32a, 32a where the handle body insertion part 32, 32 of the blade body 3, 3 is exposed in the magnet storage part 40, 40. In other words, the recess of the magnet storage part 40, 40 reaches the blade body storage part 21, 21 of the handle body 2, 2, so that a part of the handle body insertion part 32, 32 of the blade body 3, 3 inserted in the blade body storage part 21, 21 is exposed in the magnet storage part 40, 40, and is the blade body exposed part 32a, 32a. Such blade exposed portions 32a, 32a serve as the adsorption portions 43, 43 of the magnet housing portions 40, 40. When the magnets A, A are housed in the magnet housing spaces 42, 42 of the magnet housing portions 40, 40, they are magnetically attracted to the adsorption portions 43, 43 (blade exposed portions 32a, 32a), and the housed state of the magnets A, A is maintained.

[0021] In this embodiment, the adsorption portions 43, 43 utilize the blade exposed portions 32a, 32a, but are not limited to this embodiment and may have a thin wall between the blade exposed portions 32a, 32a and the magnets A, A, or may have a magnetic body for magnet adsorption arranged separately from the blade.

[0022] The bottom surface of the magnet storage parts 40, 40 has hollow parts 44, 44 as well as adhesive parts 43, 43. In this embodiment, the hollow parts 44, 44 are located on the front side of the adhesive part 43 in one handle body 2, and on the back side of the adhesive part 43 in the other handle body 2. Scissors 1 are a pair of intersecting blades 3, 3, and the handle body insertion parts 31, 31 of the blades 3, 3 are not flush with each other, and there is a misalignment between the front side and the back side (see FIG. 1(b)), so that the blade body 3 inserted into the upper handle body 2 in FIG. 1 is inserted into the front side of the handle body 2 (the front side above the figure), and the blade body 3 inserted into the lower handle body 2 in FIG. 1 is inserted into the back side of the handle body 2 (the rear side above the figure).

[0023] 3, inside the magnet storage parts 40, 40, the adsorption part 43 which is the exposed part 32a of one handle insertion part 32 is located on the front side of the magnet storage part 40, and forms an open hollow part 44 on the back side. The adsorption part 43 which is the exposed part 32a of the other handle insertion part 32 is located on the back side of the magnet storage part 40, and forms an open hollow part 44 on the front side.

[0024] The magnet storage portions 40, 40 have protruding edges 41, 41 around their periphery, and guide openings 45, 45 are provided by cutting out a portion of the protruding edges 41, 41. The guide openings 45, 45 are inclined to communicate with the magnet storage portions 40, 40, and more specifically, the guide openings 45, 45 communicate with the hollow portions 44, 44, rather than with the attraction portions 43, 43 of the magnet storage portions 40, 40. In other words, the communication paths 46, 46 inclined from the guide openings 45, 45 reach the hollow portions 44, 44 of the magnet storage portions 40, 40.

[0025] In addition, the presence of the hollow portions 44, 44 makes it possible to abut a rod-shaped tool B (see FIG. 6) such as an awl against the back side of the magnet A. The communication passages 46, 46 are guides for leading the material from the guide openings 45, 45 to the hollow portions 44, 44, and have a downwardly sloping surface.

[0026] The method of attaching the blades 3, 3 to the handle bodies 2, 2 and attaching the magnets A, A to the magnet housings 40, 40 of the handle bodies 2, 2 will be described. First, the handle body insertion sections 32, 32 of the blades 3, 3 are inserted into the blade body housings 21, 21 inside the handle bodies 2, 2. At this time, the engagement step section 34 of the blades engages with the engagement section 23 of the handle bodies 2, 2, which acts as a stopper that allows only the trunk of the blade body 3 to be inserted. This completes the attachment of the blades 3, 3 to the handle bodies 2, 2, and in this state, the blade exposed sections 32a, 32a, which are part of the blade body insertion section 32, are exposed in the magnet housings 40, 40.

[0027] The magnets A, A are accommodated in the magnet accommodating spaces 42, 42 of the magnet accommodating parts 40, 40. At this time, the accommodated magnets A, A are magnetically attracted to the adsorption parts 43, 43 (blade exposed parts 32a, 32a) on the bottom side of the magnet accommodating parts 40, 40, which are on the front side on one hand and on the back side on the other hand, thereby completing the accommodation of the magnet A in the magnet accommodating parts 40, 40.

[0028] As a result, the magnet housing units 40, 40 can assist and guide the scissors 1 from the closed state (the state in FIG. 1) to the open state by the repulsive force of the magnets A, A. This allows people who use scissors frequently, such as agricultural workers, to easily continue using the scissors 1. It is also possible to assist and guide the scissors 1 from the open state to the closed state by utilizing the attractive force of the magnets housed in the magnet housing units 40, 40.

[0029] The above is how to use scissors that use magnets, but there are cases where the user wants to choose between using the repulsive force or the attractive force of magnets A, A, and even if only one of them is used, it becomes necessary to select a magnet to achieve an appropriate repulsive force. In such cases, it is necessary to remove magnets A, A housed in magnet housing parts 40, 40 and replace or change their position.

[0030] A method for removing the magnets A, A from the magnet storage parts 40, 40 will be described. Fig. 6 shows the process of removing the magnet in an oblique view and in a cross section. A rod-shaped tool B such as an awl is inserted through the guide openings 45, 45. At this time, the guide surfaces of the communication passages 46, 46 guide the rod-shaped tool B such as an awl toward the hollow parts 44, 44. The guided rod-shaped tool B such as an awl reaches the hollow parts 44, 44, and can be removed from the magnet storage parts 40, 40 by abutting it against the back side of the magnet A and pulling it out. By performing the above mounting operation again, it is possible to mount a magnet with a different magnetic force. The opposing magnet A is also removed in the same way. [Explanation of symbols]
