Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a key for a magnet lock.
[0002]
[Prior art]
The magnet lock, which prevents the rotation of the lock cylinder with a magnet and inserts a key that holds the magnet in a position corresponding to the position of the lock magnet, moves the lock magnet and rotates the cylinder. Widely used.
[0003]
FIG. 10 is a perspective view of a key 90 of a conventional magnet lock, and FIG. 11 is a view of FIG. 10 viewed from a direction D. Reference numeral 91 denotes a concave portion for holding a magnet, and 92 denotes a projection for positioning when inserting the key. . Although the magnet is inserted into a specific position among the plurality of magnet holding recesses, the magnet cannot be held as it is, and the inconvenience that the position of the magnet can be determined is inevitable.
[0004]
Thus, by covering the magnet holding concave portion with the metal plate 93 as shown in FIG. 12, the magnet can be held and the position of the magnet can be made invisible.
[0005]
[Problems to be solved by the present invention]
In the above-mentioned conventional keys, the cover of the metal plate causes an increase in cost, and it is also difficult to finish the keys in various colors.
[0006]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides a key for a magnetic lock, in which the key is composed of two parts, a key grip part and a magnet holder part. And a projection formed on the engagement locking portion and a locking hole formed on the key grip portion are engaged to fix the key grip portion and the magnet holder portion. It is obtained.
[0007]
【Example】
FIG. 1 is a front view of a key assembly 10 of the magnet lock of the present invention, FIG. 2 is a top view of FIG. 1 viewed from the U direction, FIG. 3 is a bottom view of FIG. 1 viewed from the D direction, and FIG. 5 is a cross-sectional view taken along line XX of FIG. 1, and FIG. 6 is a perspective view of the key assembly 10 exploded into a key grip portion 20 and a magnet holder portion 30, respectively.
[0008]
The magnet holder part 30 includes a fitting and locking part 31 and a magnet holding part 33, and the fitting and locking part 31 is fitted into the central concave part 24 of the grip body 21 of the key grip part 20. (See FIG. 5) The locking projection 32 formed in the fitting and locking portion 31 and the locking hole 22 formed in the grip body 21 are engaged, and the key grip 20 and the magnet holder 30 are fixed. You. Note that an upper hole 23 is formed in the grip body 21.
[0009]
The magnet holding portion 33 of the magnet holder portion 30 has a magnet holding recess 34 in which a magnet 51 is held. (Three in the illustrated example) 35 is a protrusion, and 36 is a notch, which respectively engage with a cylinder of a magnet lock described later. Various keys are formed by changing the positions of these projections and notches, the positions of the magnet holding concave portions, and the like.
[0010]
7 is a sectional view of the magnet lock 40, and FIG. 8 is a perspective view of the magnet lock 40 exploded into a cylinder 41, a cylinder holder 47, and a cylinder stopper 43.
[0011]
The cylinder 41 has a key insertion recess 42 into which the magnet holding portion 33 of the key assembly 10 is inserted, and a notch 45 engaging with the projection 35 and a projection 46 engaging with the notch 36 are formed on the periphery thereof. Have been. A concave portion 63 into which the cylinder 41 enters and a plurality of concave portions 48 into which a magnet fits are formed in the cylinder holder 47. (8 in the example shown)
[0012]
A square shaft 61 is formed below the cylinder 41, and is engaged with a square hole 62 of the cylinder stopper 43 through a hole 64 of the cylinder holder 47. The cylinder 41 and the cylinder stopper 43 are fastened by screws 65 with the cylinder holder 47 interposed therebetween. Reference numeral 44 denotes a screw hole in the square shaft 61.
[0013]
A magnet fitting recess 49 is formed on the bottom surface of the cylinder 41 so as to be located at a position corresponding to the magnet fitting recess 48 of the cylinder holder 47. A magnet 52 and a magnet spring 53 are fitted into the recess 49, Reference numeral 52 is urged by a magnet spring 53 and pressed into the magnet fitting recess 48 of the cylinder holder 47. (See FIG. 7) In the example shown in the figure, magnets 52 are inserted into three specific recesses among the eight recesses.
[0014]
As can be seen from FIG. 7, the magnet 52 is normally urged by the magnet spring 53 and enters the magnet fitting concave portion 48 of the cylinder holder 47, and exists between the concave portion 49 of the cylinder 41, so that the cylinder cannot rotate. The lock 40 is in the locked state.
[0015]
FIG. 9 shows a state where the key assembly 10 is set on the magnet lock 40. The magnet holding portion 33 is inserted into the key insertion recess 42 of the cylinder 41. If the arrangement of the magnets on the bottom surface of the cylinder 41 matches the arrangement of the magnets on the key, the magnet 52 on the cylinder rises against the magnet spring 53 as shown in FIG. The key assembly 10 is disengaged from the concave portion 48 of the cylinder holder 47, the rotation of the cylinder 41 is no longer restricted, the cylinder 41 becomes rotatable, and the key assembly 10 has its projection 35 engaged with the notch 45 of the cylinder 41, and the notch 36 Since the key assembly 10 is engaged with the projection 46, the cylinder 41 also rotates when the key assembly 10 is turned, and can be unlocked.
[0016]
As described above, the key of the magnet lock according to the present invention is divided into the key grip portion and the magnet holder portion, and the magnet is sealed at a predetermined position. Therefore, a metal plate cover is unnecessary, cost can be reduced, and the key grip portion is optional. Color and the appearance can be a desired color.
[0017]
【The invention's effect】
The key of the magnet lock according to the present invention has the above-described configuration, so that the cost can be reduced and keys of various colors can be arranged.
