Abstract

The present invention provided a interlocking tool which is easily and surely perform attachment and detachment by feeling without looking. This interlocking tool is composed of a planar male member 10 provided with a projection 11 whose tip is expanded and a planar female member 20 provided with a channel part 21 capable of fitting the projection 11. In this case, one end of the channel part is opened to the outer periphery of the female member, the other end is closed, both end parts of a spring wire 23 are projecting to the inner side of the channel part and form projecting parts 23a, 23a near the closed end 21a and the projection 11 is snap-fitted.

Description

The hasp of usefulness such as necklace

The present invention relates to ornaments such as necklace are hung over the hasp on the positions such as neck.

As shown in Figure 5, when necklace is hung over neck, an end of necklace 1 is connected with U-shaped spring members 2, the other end is connected with the socket part 3 of the insertion mouth 3a with spring members 2, and fix by spring members 2 being pressed into an aforementioned insertion mouthful 3a, the hasp of Lian Jieing is being extensive use of like this.

Yet at the fixing above-mentioned hasp of neck rear side, because eyes be cannot see, can only gropingly parts 2 be inserted into parts 3 by armrest, this bothers very much, and failure easily, so often need others to help to fix.

Purpose of the present invention will provide a kind of and not see also the hasp that can install and remove reliably with the autograph letter list by eyes.

In order to implement above-mentioned purpose, first hasp of the present invention is to heave outstanding tabular projecting member by front end, constitute with tabular recessed parts with the concave part that embeds aforementioned projection, on one in above-mentioned projecting member and recessed parts magnet is housed, the ferromagnetism body is housed on another, thereby can attract each other, one end of aforementioned grooves portion is opened to the periphery of tabular projecting member, and other end sealing, and near the closure of the other end, be provided with the elastic protrusion with the inboard almost parallel of concave part, so that aforementioned projection is lockable rapidly.

The 2nd hasp of the present invention is made of tabular projecting member with projection that front end bloats and tabular recessed shape parts with the concave part that embeds aforementioned projection, the outer end of aforementioned grooves portion and inner the sealing, and near this inner closure, be provided with and the inboard parallel substantially elastic protrusion bar of concave part, thereby aforementioned projection is lockable, and can in axial direction near the outer end of aforementioned concave part, extracts aforementioned projection out.

Can on aforementioned projecting member and recessed parts one, magnet be set, the ferromagnetism body is set on another.

Aforementioned elastic protrusion bar can by near the narrow slit place the closure that is arranged on concave part ringwise the spring wire of projection constitute.

Fig. 1 is the plane of a kind of form of implementation of expression hasp of the present invention.

Fig. 2 is corresponding profile.

Fig. 3 is the profile of recessed another example of parts of expression.

Profile when Fig. 4 is in connection status for expression connects.

Fig. 5 is the schematic diagram of the original hasp of expression.

Below with reference to Fig. 1 to Fig. 4 embodiments of the present invention are described.

As illustrated in figures 1 and 2, hasp of the present invention by discoid projecting member 10 and discoid recessed parts 20 be formed in projecting member 10 above, be provided with the projection 11 that front end bloats, also can go into magnet 12 as required, be provided with the ring 13 that is connected usefulness with necklace etc. in periphery at inner setting-in.This projecting member 10 can be used magnet 12 is embedded moulding manufacturing in the synthetic resin, and also available metal sheet forms projection, and the mode that maintains magnet 12 at periphery is made.Certainly, also can make without magnet 12.

Aforementioned recessed parts 20 have the concave part 21 of the projection 11 of projecting member accepted 10.Following and the outboard end of this concave part 21 is open, above, side and medial extremity seal, but the projection 11 of aforementioned projecting member 10 is gone in intercalation in the recess that is separated by this blind end 21a.

Near the blind end 21a of aforementioned grooves portion 21 both sides are formed with narrow slit 22, protrude jut 23a, the 23a that is formed with arcuation in the part at the two ends of the inboard upper spring silk 23 from this narrow slit 22 to concave part 21.As shown in Figure 1, the both ends of this spring wire 23 bend to the U font, are flexed into correct semi-circular curvature then in the other direction.This semi-circular portion is fixed on the recessed parts 20.

As shown in Figure 3, also can make the both ends of spring wire 23 curve the U font simply, make its part to concave part 21 inboard outstanding protuberance 23a, the 23a of forming.

And outer circumference end 21 b of concave part 21 also can seal.In this case, projection 11 can in axial direction be extracted in the 21c of narrow slit portion.

When aforementioned projecting member 10 was equipped with magnet 12, above-mentioned recessed parts 20 be by can being formed by the ferromagnetism body of attraction, or at least in its part setting-in go into the ferromagnetism body.In addition, be provided with the assembly that connects usefulness such as necklace in the periphery, for example encircle 24 etc.

The occasion of the hasp of stating in the use, can make the face of the projection 11 that is provided with projecting member 10 and relatively close two parts of open surface of recessed parts 20 fovea superior slot parts 21, when the front end of projection 11 inserts concave part 21, contact with jut 23a, the 23a of spring wire 23.When the power with a little is pressed into recessed parts 20 with projecting member 10,

jut

23a, 23a that the front end of projection 11 just presses off spring wire 23 enter in the concave part 21, at last as shown in Figure 4, jut 23a, the 23a of spring wire 23 will clamp the small diameter portion of projection 11, and, when projection 11 overlap joints were connected on jut 23a, the 23a, the forward attraction of stating magnet 12 was securely fixed in projecting member 10 on the recessed parts 20.

When needs take off, can move projecting member 10 to its outer circumference end direction along the concave part 21 of recessed parts 20.As mentioned above, projection 11 by the jut 23a of

spring wire

23,23a clamping, but because this

jut

23a, 23a are arcuation, so can transfer to easily along horizontal direction (radial directions of discoid protrusion, recessed parts), and magnet 12 is also more weak along the attraction of horizontal direction (magnetic line of force cutting direction), so can take off projection 11 easily by the open end of concave part 21, it is extracted from the 21c of release portion.

And the flat shape of projecting member 10 and recessed parts can be chosen as circle, ellipse, polygon or other shape according to the difference of embodiment.

If employing the present invention, as mentioned above, can be with the projection and the concave part tabling that is arranged on the recessed parts that is arranged on the projecting member, and, aforementioned projection overlap joint is fastened, so see without eyes by making being projected into side by side in the groove of elastic protrusion bar, only just aforementioned projection embedding can be pressed into concave part gropingly with hand, thereby, projecting member and depressed portions overlap joint is fastened, only need in addition just can take apart simply to the outer circumference end direction promotion projecting member of concave part.

Claims
