Description

Locking member with triple folding {Clasp with Triple Folding}

In general, lock-type locking members for watch bands having two jointed arms are known, which are connected to each other at one end of the arm so that the diameter of the strap can be expanded. By sliding the strap over your wrist, you can remove it or re-seal it. In the folded down state, the arms leading to the joint are adapted to each other and held in place by protrusions of the other arm that are secured to the groove of one arm.

The first end of the locking member with two folding arms limits its unfolding operation, which means that the length of each folding arm must be shorter than the width of the wrist, while the user has a wide hand or a ring or other strap, etc. It is tricky to kick or remove the watchband again if you are wearing it and causes discomfort.

The second end of the locking member with the folding arm is of limited overall size, so that one arm, often connected to the joint, is folded into the space of the other arm to prevent the locking member from increasing in thickness. The thickness of the member is a critical criterion for the manufacture of watches and should be of minimum size.

The third end of the locking member with the folding arm is of limited reliability and stability, causing the locking member to be suddenly released due to age and deformation, which creates another disadvantage.

The present invention relates to a locking member, and more particularly to a locking member having a triple folding portion for a wrist watch having three folding arms that can be fastened.

It is therefore an object of the present invention to provide a solution to the above problems by devising a generally usable folding locking member for a wrist watch having a compact structure suitable for a known and proven manufacturing method.

This object is achieved by the present invention as defined by the claims.

The present invention will now be described in detail with reference to FIGS. 1 to 16.

These embodiments of the folding locking member illustrate preferred and superior aspects of the present invention, and these preferred embodiments are in no way limiting, in particular can be combined without departing from the scope of the present invention. 1 to 9 show a preferred embodiment of a folding lock, which shows steps different from the other members of the fastening and releasing mechanism of the folding device as seen from various sides and top and bottom. Figures 10-15 show a preferred embodiment of a folding lock member showing various fastenings of the folding arm, and Figures 13-15 show a preferred embodiment of a folding lock member showing a modified fastening of the cover.

In three preferred embodiments, the folding locking member has three folding arms (1, 2, 3), wherein the central arm (1) and the intermediate arm (2) are articulated to each other at one end thereof. The inner arms 1 and 2 can be fastened to each other, while the middle arm 2 and the outer arm 3 are articulated to each other at one end thereof. Once the center arm 1 and the middle arm 2 are fastened and folded down to the outer arm 3, the cover 4 provided to be foldable on the center arm 1 is folded down to the outer arm 3. It is possible to fasten the locking member. Such a structure with three folding arms is by no means limited, and those skilled in the art will appreciate that various modifications, not shown, can be achieved without departing from the scope of the invention, such as only two folding arms or three or more folding arms. A folding locking member with an arm can be achieved.

The folding locking member is characterized by three folding arms (1, 2, 3) fitted to each other, wherein the central arm (1) is between the two intermediate ends (2.1, 2.2) of the middle arm (2). The intermediate arm 2 can be accommodated entirely in the space between the two outer leading edges 3.1, 3.2 of the outer arm 3. This results in a very thin and refined structure since there are no parts added to the multiple folding arms (1, 2, 3). Preferably, the central arm 1 and the tips 2.1, 2.2, 3.1, 3.2 are connected by pins 5, 7, 8 and contact means 6.

The hinge pins 7 and 8 act as hinges for the folding arms 1, 2 and 3, and preferably the outer arm 3 and the middle arm 2 are formed at the rear end of the locking member (i.e. It is detachably connected to each other around a hinge pin (7) located at a distance from the fixing pin (5), and the middle arm (2) and the center arm (1) are connected to the front end of the locking member (i.e. It is detachably connected to each other around a hinge pin 8 located on the side where the fixing pin 5 is located.

The fastening pins 5 are fixed to the outer ends 3, 1, 3.2 with the aid of screws, which leads to a rigid and inseparable connection of the two outer ends 3. 1, 3.2 of the outer arm 3. While other fasteners can certainly be used, they are within the scope of the present invention. The fixing pin 5 can perform several additional functions. In two preferred embodiments of the locking member according to FIGS. 1 to 12, the fixing pin 5 is provided with a first watch band 100. This watchband 100 can be detachably secured, for example, made of an elastic material, in particular a leather watchband as shown in FIG. 10, for example, for other elastic watchbands such as plastic materials. The base material can certainly be used and is not limited to the present invention. In the preferred embodiment of the locking member according to FIGS. 13 to 15, the fixing pin 5 can detachably fix the first end 200 of the watch band and to secure the cover 4. do. Such watchbands have, for example, flexible connections, which are made of metal material, preferably the flexible connections are made of stainless steel or gold. Other base materials can certainly be used and are not limited to the present invention.

The contact means 6 is fixed, for example, by being pushed into the outer leading edges 3.1 and 3.2, which are securely fixed in this way to form part of the outer arm 3, and to the folding locking member. The outer ends of the outer portion (3.1, 3.2) will be further strengthened, and will further stabilize or reinforce the connection of the two ends (3.1, 3.2) of the outer arm (3) already connected to each other by the fixing pin (5). The contact means 6 can perform several additional functions. According to a preferred embodiment of the locking member shown in FIGS. 1 to 9, the transverse member 6122 of the contact means 6 has a locking member. When in the engaged state, the end of the center arm 1 and the end of the middle arm 2 can be contacted tangentially. This tangential contact of the center arm 1 and the middle arm 2 can further strengthen the fastening folding locking member. According to a preferred embodiment of the locking member shown in FIGS. 10 to 15, the transverse member 6. 2 of the contacting means 6 can be in contact with one end of the central arm 1 along the tangent line, and the intermediate arm 2 It is possible to make a contact or fastening contact with the concave end (2.6) of the), which is not limited to the middle arm (2), a plurality of folding internal arms, that is, the middle arm and the center It is possible to achieve the locking member of the notched contact with the arm. According to a third preferred embodiment of the locking member according to FIGS. 13 to 15, the tip 6. 4 of the contact means 6 is capable of indenting contact with the side wall 14 of the cover 4. The notch contact is not limited to the cover 4 and it is possible to achieve any other collapsible member of the locking element, ie the notch contact member with one or more end connections of the watch band.

Preferably, the contact means 6 is a pin that is pushed in such a way as not to be separated into the space portion of the two outer ends 3. 1, 3.2, while other fixing variants can be reliably used, while the scope of the invention Will be inside. FIG. 16 shows another preferred embodiment of the contact means 6 in the form of a crosspiece 61 inseparably mounted in a thin-walled tube 62, the preferred structure of which is shown in FIG. It is possible to reinforce the connection of the two outer ends 3. 1, 3.2 by the crossbar 61, and the thin-walled tube 62 is elastic to impart any elasticity to the contact means 6. In particular, the central portion of the crosspiece 61 is at least one reinforcement capable of making contact with the end of the central arm 1 with a thin wall of the tube 62 or along an essentially inelastic tangent of the transverse member 6. 2. The part 611 is provided. On the other hand, the part without one or more reinforcements 611 provides a space for separating the tube 62 and the crosspiece 61, for example, said elastic contact with the tip 2.6 of the middle arm 2, for example. It can be an extension of the tube 62. In order to center the center arm 1 during fastening or releasing, the crosspiece 61 is placed with a limited clearance in the guide hole of the outer leading edges 3.1 and 3.2. The elastic, metallic contact means 6 and its thin wall preferably have a thickness of 0.15 mm. At thinner thicknesses, the maximum bending stress is exceeded (deformation is so large that intermittent operation is difficult), while at higher thicknesses, the elastic modulus of the tube 62 is exceeded (deformation beyond the elastic limit at which thin walls can be returned). And the intermittent operation is not sure). Therefore, in a tube 62 manufactured using a metal material such as stainless steel, an elastic tube having a thickness of 0.15 mm is ideal, and a force or an intermittent action for fastening in a definite form (acting correctly without exceeding or insufficiently) While allowing all, still ensures easy machining of the contact means 6. It is desirable to choose a steel tube 62 of arms (1,2) or crossbars 61 that are folded from other materials (e.g., Nivaflex, Phynox, etc.), which provides good friction Coefficients are guaranteed. Due to the difference in molecular structure and hardness, it is ideal to use a pair of different materials, and the intermittent operation can be remarkably changed because the elasticity of stainless steel is not constant and its chemical properties are different from those of elastic tubes. Other base materials can be used surely and are not limited to the present invention.

The quality of the locking member is limited not only by its purely technical features, but also by its impression on the user. Unlike known locking members which do not use a thin-walled tube with a pair of different materials and an elastic contact means with crossbars, the forces can be adjusted individually, especially for the intermittent operation of the folding locking member. Features can be adjusted. For example, by replacing another tube that is thicker or thinner, or more elastic or less elastic, it is possible to individually control the response of the intermittent action, ie the ratio between the speed and the hardness of the intermittent action. This adjustment is an important feature to the user compared to the sophistication and excellence of the locking member, the speed at which the locking member can be released and fastened can also give a good impression, this feature is when buying a watch with a locking member Often the decisive factor.

When a folding locking member for an elastic watch strap (particularly a leather watch strap) according to the embodiment shown in FIGS. 1 to 12 is used, the locking member has a cover 4 with a top partially open at its center. Which results in a very flat locking member with a minimum overall length. 2 and 10 show that the second watch band 110 can be secured by being seated on a cover 4 and a rod 4.11 connecting the side wall 14 of the cover 4. have. The second watch band 110 is partly designed to bend the contact surface with the upper sidewall of the cover 4 and also to completely bend the corresponding contact surface of the rod 44.1. The shape of the contact surface of the associated member is determined in such a way that the curvature of the second watch band produced by the rod 4. 1 is received in the central opening 4. 2 above the cover 4. The curvature of the second watch band 110 generated by the bending of the inner wall of the upper cover 4 stabilizes and reinforces the fixing of the second watch band 110. Preferably, the cover 4 is detachably or interchangeably connected to the center arm 1 via a rod 4.11. 1 to 9 and 10 to 12, in the preferred embodiment according to FIGS. 10 to 12, the central opening 4. 2 is additionally located at the center of the cover 4 so as to provide a second cover 4. It provides greater space for the watch strap and differs in that the cover 4 can make a more reliable turn around the rod 4 .11 with the watch strap 110 in the form of a strap. Compared with other locking members, the appearance of the locking member is particularly refined since it is very flat with increasing thickness of the cover top open at the center. In addition, the locking member with the cover 4 open at its center does not have a heavy and rigid appearance.

The folding locking member has a first resultant between two of the two separate fastenings, ie the folding arms 1, 2, 3, and at least one of the two arms 1, 2, 3 and the cover 4. It is characterized by a second fastening formed by).

Is caught and is elastically compressed by the notch of the transverse member 6.22. Those skilled in the art will be able to achieve various modifications, not shown, without departing from the scope of the invention, for example to achieve not only the middle arm but also the locking member of the notch contact with the center arm in an ideal manner. The contact means 6 may be a rigid pin and may consist of a crosspiece 61 and a thin-walled tube 62 according to FIG. 16.

The preferred first and second embodiments according to FIGS. 1 to 12 show a second fastening state consisting of two protrusions 10 lying on the side wall of the cover 4, with the cover 4 with the outer arm 3. The protrusion 10 is located near the second pendant in the form of a gap 3.10, the side wall of the cover 4 is elastically expanded and the protrusion 10 is a gap (3.10). It is held in the second fastening position by the notch (2.5). Those skilled in the art will appreciate, without departing from the scope of the present invention, for example using the notches of the cover 4 or the projections 10 in the cover 4 together with the arms 1, 2 therein. Various variations, not shown, may be achieved, such as the use of flat sidewalls 14 inside the cover 4.

The third preferred embodiment according to FIGS. 13 to 15 is in the form of a side wall 14 in a cover 4 with a second pendant in the form of an end 6. 4 of the contact means 6 of the outer arm 3. As shown in the two fastening state, the contact means 6 is fixed in the guide hole of the outer arm 3 in such a manner that the end 6.14 thereof protrudes slightly beyond the side wall of the outer arm 3. The contact means 6 may be a rigid pin and may consist of a crosspiece 61 and a thin-walled tube 62 according to FIG. 16. The cover 4 is folded down with the folding arms 1, 2, 3 so that the flat side wall 14 is positioned near the tip 6.14 and the side wall 14 of the cover 4 is elastically extended. And held in the first engagement position. Those skilled in the art will appreciate, without departing from the scope of the present invention, for example, with the notches of the cover 4 together with the internal arms 1, 2, or instead of the flat sidewall 14 in the cover 4. Various modifications, not shown, can be achieved, such as the use of the projections 10 in (4).

The folding locking member is characterized by a new and original release mechanism. The locking member is preferably designed for use with an elastic watchband such as a leather watchband or with a watchband with a flexible connection (preferably made of stainless steel or gold). While these two exact uses of the locking member are different through the preferred embodiment of the release mechanism, these embodiments can be surely compatible with each other, while the preferred embodiment of the elastic watchband and the locking member for use is a flexible connection. Can also be used for watchbands with

The release of the fastened locking member for the elastic watch band according to the two embodiments of FIGS. 1 to 12 provides two fastening means 9, 2.6, 10, 14 with corresponding pendants 2.9, 6.12, 3.10, 6.14. This is achieved by restoring the original connection of two fastenings.

The release of the second fastening means (two projections in the side wall of the cover 4 or the flat side wall 14 of the cover 4) is for example a release force (arrow F; FIG. 10) that can lift the cover 4. By pulling the end of the second watch band 110 in the direction of FIG. By applying the releasing force F to the locking member, the side wall of the cover 4 can be pulled out, which covers each of the notches of the projection 10 or the flat surfaces of the cover 4 in the gaps 3.10. The side wall 14 of the outer arm 3, or each end 61.4 of the outer arm 3.

Thus, the released cover 4 can pivot around the rod 4.11. When the second watch band 110 bends the contact surface of the inner wall of the upper part of the cover 4, it preferably curves the corresponding contact surface of the rod 4. 1, and at the center of the locking member and the locking member. Inherently bent some of the outer surface of the folding arms 2,3 defined by the hinge pins 7 located at the rear end of the cover 4, somewhat due to the elasticity of the second watch band 110 Compressed and slightly stiff. As the end of the second watch band 110 is pulled in the direction of the releasing force F, the cover 4 is more pivoted around the rod 4.11, the middle arm 2 or the outer portion of the locking member. The reaction force R transmitted to the second watch band 110 supporting in the region 23 on the outer surface of the arm 3 becomes larger. This stiffness is not necessary, but the folding arms 2, 3 will help support the watch strap. Those skilled in the art will appreciate that various modifications, not shown, can be achieved without departing from the scope of the invention, such as the use of watches with flexible connections or partially reinforced elastic watches.

The watch band 110, the cover 4, and the center arm 1 connected to the watch band form a lever capable of supporting the outer surface of the middle arm 2 or the outer arm 3. By using the reaction force R, the lever uses the tangent at the end of the center arm 1 with the first pendant in the form of a transverse member 6. 2 of the contact means 6 of the outer arm 3 (see FIG. 11). It is possible to stop following contact. This separation of the end of the center arm 1 is essentially achieved by pivoting the center arm 1 around the contact means 6. The contact means 6 can be a rigid pin, consisting of a crosspiece 61 and a thin-walled tube 62 according to FIG. 16.

Once the watch arm 110 is pulled continuously with the releasing force F to lift the cover 4 so that the center arm 1 is separated and further extended, the longitudinal axis of the center arm 1 and the middle arm 2 The formed opening angle α is increased so that the concave end of the intermediate arm 2 with the first pendant in the form of a transverse member 6. 2 of the contact means 6 of the outer arm 3 (see FIG. 12) (2.6). The first fastening means can be further released by removing the notch. The release of this concave end (2.6) is achieved by using the intermediate arm (2) and a thin-walled elastic tube when using the contact means (6) consisting of a crosspiece (61) and a thin-walled tube (62) according to FIG. This is essentially done by elastically reducing the pressure 62.

The release of the fastened locking member for the watch band with the flexible connection according to the third embodiment shown in FIGS. 13 to 15 is accomplished by successively restoring two fastenings of the two fastening means with corresponding pendants.

The release of the second fastening means (sidewall inside the cover 4) is achieved by, for example, lifting the cover 4 in the direction of the force F '(see Fig. 14) for releasing the cover. By applying a force F 'for releasing the cover to the locking member, the side wall of the cover 4 fastened by the notch together with the tip 6. 4 of the contact means 6 of the outer arm 3 can be pulled out. Will be. Those skilled in the art will appreciate that various modifications can be made without departing from the scope of the invention. Instead of the projections provided on the sidewalls of the cover, it is possible to use flat sidewalls of the cover in order to be able to engage the notch with the end of the contact means of the outer arm. The transverse member of the outer arm may be provided with a contact protrusion, which may replace the end of the contact means. The contact means 6 may be a rigid pin with a tip 6. 4 and may consist of a crosspiece 61 with a tip 6. 4 according to FIG. 16 and a thin-walled tube 62.

When the locking member is in the fastened state, the cover 4 is partially seated in the end connector 40. The released cover 4 can pivot around the fixing pin 5, and the second watch band 210 with the end connection 40 is accessible. The correct function of the cover 4 is to prevent any accidental release of the end connection 40 on which the releasing force F acts. Preferably, the cover 4 is partially seated in the projection 44 of the end connection 40. In particular, the contact end and the end connection portion 40 of the cover 4 are adapted to each other, the appearance of the locking member is very flat and refined. Compared with other locking members, the thickness is achieved by flattening the upper end of the contact end of the end connection part 40, which is the cover 4 and the end connection part 40 when the cover 4 is seated in the end connection part 40. The separation between) is indistinguishable. The end connections 40 are compatible with each other around a fixing pin 50 located in the space of the central arm 1. By pulling the end of the second watch band 210 in the direction of the release force (F), the end connection portion 40 is pivoted around the fixing pin 50, the locking member for transmitting the reaction force (R) It is supported in the region 23 of the outer surface of the outer arm 3 of. Those skilled in the art will appreciate that other modifications may be made without departing from the scope of the invention.

The watch band 210, the end connecting portion 40, and the center arm 1 form a lever that can support the outer surface of the outer arm 3. By using the reaction force R, the lever can pivot the central arm 1 around the first pendant formed by the contact means 6 of the outer arm 3 (see FIG. 15).

Once the central arm 1 is released from the tangent contact or notch contact, and the pulling of the watch band 210 with the force F to release the end connection 40 further, the central arm 1 and The opening angle α formed by the longitudinal axis of the intermediate arm 2 is increased to form a cross member 6.1 of the contact means 6 of the outer arm 3 (not shown but similar to that in FIG. 12). The concave end (2.6) of the intermediate arm (2) with one pendant is able to release the first fastening means by leaving the nick. The release of this concave end (2.6) is achieved by using the intermediate arm (2) and a thin-walled elastic tube when using the contact means (6) consisting of a crosspiece (61) and a thin-walled tube (62) according to FIG. This is essentially done by elastically reducing the pressure 62.

The main advantage of this lever release mechanism for supporting the watch strap 110 on the folding arms 2 and 3 is that the locking member can be released with a relatively small release force F, so that the release force can be released. Compared with the release of the conventional locking member obtained by directly pulling the arm, the lifting lever release mechanism according to the present invention can significantly reduce the release force. In the preferred embodiment shown in FIG. 10, the necessary release force when directly pulling the non-removable folding arm of the lever defined by the distance between the supporting area 23 and the transverse member 6122 of the contact means 6. The release force F can be reduced by the factor of the contact means 6 compared to. Those skilled in the art will be able to achieve other variations of the lever, not shown, that utilize ratios of larger or smaller levers without departing from the scope of the present invention.

The folding locking member is characterized by a double unfolding, which increases the diameter of the watch strap and slides over the wrist so that it can be easily removed and put back into position. In general, three folding arms are used instead of two, in that the release of the folding locking member causes the diameter of the watchband to be as large as the same size, which the user can easily remove, after which the watchband It is important for users who have a wide or large hand, or wear a ring or other strap, while also allowing them to be kicked again.

The folding locking member consists of a small number of members, which can be easily replaced and adjusted, and easily changing the force of the first fastening by replacing the spring ball or the concave end with another spring ball or another concave end having different elastic characteristics. It is possible to change or adjust the force of the second fastening by replacing the cover with another cover having protrusions or inner sidewalls, while the other shape can be adjusted or adjusted. Those skilled in the art will appreciate that various modifications can be made.

The visible members of the folding locking member are preferably metal and are made of stainless steel or gold, although other base materials can be used explicitly and are not limited by the present invention. All visible members of the folding locking member, ie the folding arms, the cover and the pins, are preferably machined from a rigid metal block and connected by secure fastening, which allows easy change of machining and quick appearance of the locking member. do. In addition, when these members have important coordination and stability, reliable operation and easy maintenance are ensured. Another important advantage is that welding is completely prevented, in that the high precision required for easy and repeated operation of the locking member and the technical difficulties encountered during handling of the selected material (decreased hardness and unbalanced deformation during welding) It is preferable to prevent the welding. Those skilled in the art will be able to reliably achieve other fastening means for other base materials such as heat melting for synthetic heat soluble materials and the like.

As described above, according to the present invention, by providing a folding lock member for a watch which can be generally used with a suitable compact structure, it does not limit the unfolding operation, the thickness of the member is a minimum size, reliability and stability It is effective to prevent the problem of suddenly loosening the locking member because of the old and deformed.
