Description

  The present invention relates to a buckle using a magnet. This buckle can be used for belts and straps (hereinafter collectively referred to as “belts”) such as clothes, bags, and footwear.

  Well-known belts using buckles can be adjusted in length at both ends of the belt by drilling a plurality of holes at regular intervals on the belt side and selectively inserting protrusions on the buckle side into the holes. To be joined.

  Such buckles require complex movements of the hands and fingers and are difficult to use for infants and people with disabilities. Also, when used as a buckle for footwear, such as shoes and sandals, it is difficult for ordinary people to tighten the belt with an unreasonable posture while twisting the body in a bent state.

  Thus, a type of invention has been proposed in which a pair of magnets are provided on the buckle to join the two ends of the belt by the magnet's attracting force (see, for example, JP-A-2002-191410). The buckle is provided with an uneven portion which is a means for causing the two members to be adsorbed by a magnet and for instantly engaging the two members.

The prior art is desired to be improved in the following points.

(1) A belt is attached to both ends of the buckle, but no belt is attached to the buckle body. Therefore, the belt length cannot be adjusted.

(2) The magnet is simply attached with an adhesive and may peel off over time.

(3) Since the uneven portion which is a means for engaging the two members used together with the magnet is one place, the engaging force is weak against the twist.

(4) When used as a buckle for shoes or sandals, a strong force is applied from the back of the foot, but with this conventional technology, the distance from the power point to the fulcrum is long, and there is a risk that the force from the back of the foot cannot be withstood. There is.

The present invention has been made to eliminate the drawbacks of the prior art, and provides a belt that can adjust the length of a belt while using a magnet. Moreover, the strong attachment method of a magnet is also provided.

The present invention is a buckle comprising a first member and a second member that can be joined and detached, wherein the first member comprises a first substrate made of a nonmagnetic or low magnetic material, a belt insertion hole, A protrusion for selectively adjusting the length of the belt by being selectively inserted into the hole on the belt side, a first magnet for joining, and an engaging means for positioning and joining reinforcement, and the second member includes: Positioning and bonding that can be engaged with the second substrate made of a non-magnetic or low-magnetic material, a belt insertion hole, a bonding second magnet that can be adsorbed to the bonding first magnet, and the first means. And a second engaging means for reinforcement.

Preferably, the first and / or second magnet is a rectangular thin plate, has a through-hole extending toward the bonding surface side, and the first and / or second substrate has a pin, This pin is inserted into the through-holes of the first and / or second magnets and is deformed by pressure to prevent caulking (Claim 2).

Preferably, the first and / or second magnets are neodymium magnets having a BH max (maximum energy product) of 300 to 500 (Claim 3).

Preferably, the engaging means for positioning and bonding reinforcement of the first and / or second substrate is one protrusion and the other through hole. It is preferable to provide two each (claim 4).

The buckle of the present invention can be widely used for clothes, bags and footwear, but is particularly preferable for footwear (shoes and sandals).

  According to the buckle of the first aspect of the present invention, the first and second members both have magnets and can be joined by adsorbing them, so that even infants and people with disabilities can easily attach and detach. it can. Further, since the first and / or second substrate has engaging means for positioning and joining reinforcement, it has a strong engaging force in the longitudinal direction of the belt. Further, since the first member has a protrusion for selectively inserting into the hole on the belt side and adjusting the length of the belt, the length of the belt can be adjusted.

  According to the buckle of the present invention, the first and / or second magnet is a rectangular member having the same shape which is firmly caulked in a substrate made of a nonmagnetic or low magnetic material. The rotation of the buckle is suppressed by the action of the rectangular magnets, and the first and second members are stably guided to the correct position and joined.

  According to the buckle of claim 3 of the present invention, there is provided a buckle using a magnet that is considered to have the best use conditions at present.

  According to the buckle of the fourth aspect of the present invention, since there are two concavo-convex portions as means for engaging the two members used together with the magnet, they are stable against twisting.
