Detailed description of the invention
The present invention relates to for wrist-watch or the bangle of bullion or analog or the field of wrist strap.
As shown in the figure, the present invention relates to a kind of expansion or collapsible clasp 1, this clasp 1 comprises around the first hinged arm 2 and the second arm 3 of supporting member 4.First arm 2 is hinged on the first horse stirrup 5, and the second arm 3 is hinged on the second horse stirrup 6.
According to the present invention, described first horse stirrup 5 forms a part for the first single-piece cap 7, the basal surface 71 of this cap 7 is defined for the space 72 that wrist strap band (wristband strand) passes together with one end 23 of the first arm 2 in any position of described end 23, the thickness of this wrist strap band is less than or equal to given thickness E P.
Described second horse stirrup 6 forms the bottom of the second removable cap 8, and comprise at least one fixture 61, this fixture 61 is arranged through the hole clamping around wrist strap band and mutually cooperates with the complementary fixture 81 of the removable top 82 of described second cap 8, to regulate the useful length of the wrist strap band clamped by this fixture.
More specifically, according to expansion of the present invention or collapsible clasp 1 for having the flexible wristband of given thickness E P.Second arm 2 extends between first end 22 and the second end 23; Second arm 3 extends between first end 32 and the second end 33.
Supporting member 4 extends between the first hinge 41 and the second hinge 42.
First arm 2 is hinged on the first hinge 41 at its first end 22, and is hinged on the first horse stirrup 5 at its second end 23.
Second elastic arm 3 is hinged on the second hinge 42 at its first end 32, and is hinged on the second horse stirrup 6 at its second end 33.
First horse stirrup 5 comprise the first arm 2 the first joint pin 51 and for being fixed to the second pin 52 on fixing wrist strap band, this wrist strap band has the thickness being less than or equal to given thickness E P.The basal surface 71 hidden of the first cap 7 together with the second end 23 of the first arm 2 the random angle position of the second end 23 be defined for the wrist strap band with the thickness being less than or equal to given thickness E P pass through described in by space 72, be used for the guided rings of such wrist strap band to be formed.
Preferably, first arm 2 comprises first can (elastically withdrawable) locking device 21 of returning of elasticity, second arm 3 comprises second can the locking device 31 return of elasticity, supporting member 4 comprise be arranged in latched position respectively with the first locking device 21 and co-operating first complementary locking device 421 and the second complementary locking device 431 of the second locking device 31.
First arm 2 and the second arm 3 can be formed by the U-shaped arm of " tuning fork " shape, described U-shaped arm has the elastic arm of carrying first locking device 21 and the second locking device 22, and described first locking device 21 and the second locking device 22 are especially formed by tongue or groove.But the first complementary locking device 421 and the second complementary locking device 431 are formed by groove or tongue respectively.
Curving through of elastic arm is of short durationly return the first latched position 21 and the second latched position 22 and allows the folding position that the first arm 2 and the second arm 3 move to supporting member from the open position seen in figs. 3 and 4.Once align with supporting member 4 in the first arm 2 and the second closed position of arm 3 shown in Fig. 1, Fig. 2 and Fig. 5, elastic arm just return in place and cause the first locking device 21 and the second locking device 22 respectively locking device 421 complementary with first and the second complementary locking device 431 mutually cooperate to lock, and do any action without the need to user.
Advantageously, the first single-piece cap 7 is included in the first convexity part (cabochon) 73 on the opposite side of bottom surface 71 and the first horse stirrup 5.Second cap 8 comprises the second convexity part 83 in a similar fashion.
In the closedown latched position of clasp 1, the first edge surface 74 of the first convexity part 73 is resisted against on the right edge surface 84 of the second-phase be included in the second convexity part 83.
User can therefore easily visual examination clasp whether lock rightly, any gap between convexity part 73 and 83 all represents unrealized locking.
In the flexible program shown in Fig. 7 and Fig. 8, the first convexity part 73 comprises safe locking device 75, and the closedown latched position that this safe locking device 75 is arranged in clasp cooperates mutually with the complimentary security locking device 85 be included in the second convexity part 83.
In non-limiting example, exemplarily, the first convexity part 73 and the second convexity part 83 together with the closedown latched position of clasp, form the applicant product specific to 8-shaped.Here the side of the first convexity part 73 is hinge 76, and the female part 77 of the transfer arm carrying 8-shaped of this hinge 76, this part 77 is designed to two convexity parts 73 and 83 to be clamped together.Here, the parts 75 of above-mentioned shape at one end carry lip 75, this lip 75 be arranged in by hinge downwards after folding 180 degree the position of Fig. 8 with to be assembled on the second convexity part 83 and to form the spring 85 of complimentary security locking device or like cooperates mutually.
In order to regulate the length of the adjustable band 12 in the space 72 that is inserted between the first horse stirrup 5 and the basal surface 71 of the first cap 7, as shown in Figure 5, except fixture 61, second horse stirrup 6 also comprises at least one and the co-operating pin 62 in hole 86 in the removable top 82 of the second cap 8, or hole 63 co-operating with the pin 83 of removable top 82 on the contrary, described fixture 61 here by with sleeve 81(here, the base portion 87 of sleeve 81 and the second cap 8 is one) co-operating screw formed.Sleeve 81 and pin 62 or 83(are according to circumstances) mutually cooperate with the hole 123 in wrist strap band 12.
The present invention relates to a kind of wrist strap 10, this wrist strap 10 comprises the expansion of at least one the above-mentioned type or collapsible clasp 1 and the first fixing strip 11 and the second adjustable band 12 around at least one clasp 1 described, and the thickness of described band is less than or equal to described given thickness E P.
First band 11 is passed through the first joint pin 51 of the first arm 2 on the bearing of trend of the first band 11 and is fixed on the first horse stirrup 5 by the second pin 52 crossing the first band 11.So the first band 11 limits the space 72 being arranged for the second band 12 and passing together with basal surface 71.At least one fixture 61 that second band 12 clamps via the hole 123 around the second band 12 is fixed on the second cap 8 with mutual cooperation of the complementary fixture 81 of the removable top 82 of the second cap 8.
In a particular embodiment, the first fixing strip 11 and/or the second adjustable band 12 are flexible strips.
The invention still further relates to a kind of clock and watch or bullion 100, these clock and watch or bullion 100 comprise wrist strap or the bangle 10 of at least one the above-mentioned type, as shown in Figure 8.The invention enables the clasp 1 that can be formed and make people remember the shape of shell 101, especially watchcase.
In unshowned specific embodiment, the first convexity part 73 and/or the second convexity part 83 use in visible mode, and carry watch and clock movement or jewel or analog.In fact, except the mechanical performance of operability and security, the present invention also has special taste, and clasp 1 becomes the decorative element of wrist strap 10.
In brief, the invention provides the combination of following devices:
-regulate the adjusting device of adjustable band, this adjusting device to avoid must to cut band to be applicable to user;
-there is the articulated structure of three elements, this articulated structure is easy to activate and stop using;
-execution is used for the first horse stirrup of the function of the ring of the end of adjustable band;
-locking closed position abut against each other (and to intersect form) two convexity parts between mutual cooperation, this results in and check whether and achieve appropriate device of closing.
