Description of drawings

After reading following description taken together with the accompanying drawings, can understand the present invention better, in the accompanying drawings:

Fig. 1 is the decomposition diagram of two arms,

Fig. 2 be locking system male part perspective view and

Fig. 3 shows locking system with the feature top view, is respectively at the unlocked position at a place and at the locked position at b place.

The specific embodiment

Fig. 1 shows the fasteners that is used for wrist strap or bracelet according to the present invention.Have longitudinal axis AA, fasteners comprises two rigid arm, promptly by being positioned at one end place and perpendicular to 14 upper arm 10 connected to one another and the underarms 12 of the articulated mounting on the axis BB of AA.Its each other end has the device 16 that is connected to wrist strap or bracelet.

Fasteners has the locking system of catching, and it comprises male part 18, the female part 20 that is arranged in close jockey 16 on underarm 12 and the upper arm 10, and the elastic component 21 that connects female part.

Male part 18 include on the end face of underarm 12 by be positioned at upstream edge 24, the lateral edge 26 on jockey 16 sides and be positioned at that downstream edge 28 on hinge 14 sides limited base 22, and the length that is arranged on the base 22 is that L, width are that I, thickness are the rectangular shaped bolt 30 that e and longitudinal axis CC are parallel to AA.Especially as shown in Figure 2, bolt 30 is installed in less than bolt and highly on the base portion 32 of h.

Elastic component 21 is made of two 21a of branch and 21b, and they are by the thickness of the upper wall of arranging along axis AA 10 that central channel 34 limits and passes.

Female part 20 is parallel to AA, length L by its axis DD ' be slightly smaller than width I and constitute greater than bolt length L and its width I ' less than the rectangular opening 36 of bolt length L.Hole 36 be arranged as when two arms abut against each other, be positioned at bolt 30 above.And because width I ' is slightly smaller than I, the joint of bolt 30 in hole 30 forms catches.

The thickness of arm 10 is limited by the depression 38 that is arranged on its end face at 36 places, hole.The degree of depth of depression 38 is substantially equal to the thickness e of bolt 30, and the thickness of arm in this position is slightly smaller than the height h of base portion 32.

Thereby, when hope closure fasteners, only need one of upper arm 10 and underarm 12 are abutted against another.The edge 40 that bolt 30 is parallel to AA becomes and contacts with the edge 42 in hole 36.Must on arm, exert pressure then so that they are closer proximity to each other.Edge 40 is pressed on the edge 42, so that bolt 30 moves away from another with one of resilient limb 21a and 21b.Thereby bolt 30 passes the path in hole 36 and has formed and catch.

At locked position, bolt 30 is contained in the depression 38 and its edge 40 abuts against on the edge 42 in hole 36, but is at this moment on upper arm 10 end faces one side.21a of branch and 21b are moved resistance separately to be enough under most of situations fasteners be remained on locked position.

In order to open fasteners, the power that must apply moves to away from each other with the end that each

arm

10 and 12 is fixed to wrist strap.Be readily appreciated that this power must be enough to overcome the 21a of branch and 21b is moved resistance separately and allow bolt 30 to pass hole 36 once more.

Much with the wrist strap of this tuning fork fasteners operate Already in the market.Yet, be easy to by mistake open on the fasteners certain degree, for example for no other reason than that wrist strap be hung on the clothes.

In order to prevent this problem, bolt 30 visible axis E E in Fig. 2 pivotally is installed on the base 22, and axis E E is perpendicular to the plane that is limited by base 22 and pass its center.Curved bar 44 is fastened between bolt 30 and wedging base 22 and the base portion 32.Outstanding and terminal being arranged in its edge from arm 12 allows wearer's pivot to rotate the knob 45 of bolt 30.

The stroke of bar 44 and therefore the rotation of bolt 30 limited by the side of bar 44 near base 22 edges.More specifically, bar 44 is so shaped that:

-in primary importance, its axis CC near the downstream edge 28 of base 22 and bolt 30 be parallel to hole 36 axis DD (Fig. 3 a) and

-in the second place, it becomes about 45 (Fig. 3 b) near the upstream edge 24 of base 22 and the axis CC of bolt 30 with the axis DD in hole 36.

First and second positions of bar 44 are by 46 marks of projecting part, thus this projecting part 46 be arranged on the base 22 contact with bar 44 so that bar with catch near forming thereon near relative side, the side of base.

Bar 44 enough elasticity are so that the projecting part that just slided just can reach the second place from primary importance.

On upper arm 10, depression 38 is enough to make when fasteners is in locked position (Fig. 3 b) for circular and its size, bolt 30 when pivot rotates in access wherein.

Thereby when wishing the locking fasteners, at first inspection bar 44 is in its primary importance so that the axis CC of bolt 30 is consistent with the axis DD in hole 36.Bolt 30 can engage into wherein and occupy foregoing depression 38 then.

Locked position blocks by actuator lever 44 subsequently, and bar strides across projecting part 46 and reaches its second place, makes bolt 30 pivot in depression 38 rotate.No longer consistent with the axis DD in hole and two opposite edges of its axis CC are positioned on the depression 38, thereby have prevented any relative motion of the arm 21a and the 21b of fasteners.

Thereby advised a kind of fasteners with the portion of catching, in case its locking just can be blocked in this position.Thereby prevented that any of fasteners from opening unintentionally.And, more than describe just providing by way of example and the present invention is not limited to specific embodiment.The present invention can easily be applied to any fasteners capture systems, for example has spring-loaded ball.

For bigger operating flexibility is provided, bar 44 also can be made of two parts, and a rigid element is incorporated into bolt 30, and another compliant member is fixed to base portion 32 below first parts and the linking arm 12 by knob 45.Therefore, bar 44 frictionally is assembled on the arm 12, thereby has prevented any danger of rocking.
