Definitions
- the present invention relates to cufflinks.
- Conventional cufflinks are one-piece, comprising a decorative element and a link member integrally provided therewith.
- the link member bears an engaging element rotatable in an axial plane. This engaging element has to be inserted through the button holes of a shirt cuff, keeping it in a straight line, and then to be rotated so as to securely attach the link to the cuff.
- the present applicant has proposed several improvements to ameliorate such drawbacks, and has obtained the issued Utility Model Nos. 1253159, 1253166 and 1253167 on October 31, 1978 in Japan.
- Preferred embodiments provide a cufflink which permits easy assembly and fixing through the button holes of a cuff, readily effectable with one hand. Furthermore, the construction and manufacture of the links may be much simpler than those of the links just described. Thus, the number of separate components may be reduced, and the troublesome operation of securing small components with tiny screws may be avoided.
- a cufflink comprising a releasably interconnectable head element and shank element, wherein the head element includes a rear wall portion having an aperture (4a) into which a head end portion of the shank element is insertable, there being spring clip engagement means for releasably retaining the inserted shank head end portion, said engagement means comprising a spring clip having a pair of laterally spaced, generally U-shaped legs having respective free end portions nearest one another and having respective opposite ends joined by a rim, said free end portions being normally urged to lie adjacent said aperture at respective sides thereof so as to restrain inward passage of the shank element; said rim, in the vicinity of said free end portions having an arcuate bridge portion; all of said spring clip except said bridge portion lying generally in a common plane, and said bridge portion being resiliently urged to be at an acute angle which intersects said common plane, and said rear wall portion including means for engaging said bridge of said spring clip to the head element with said rim resiliently torsionally stressed
- the first embodiment (shown in Figs. 1 to 18) has a head element 1.
- This has a casing shell 3 whose general form is that of a rectangular box with an open back.
- a separate engaging shank element 2 is disassemblably attached, so as to form a cufflink.
- the casing shell 3 may comprise a precious metal.
- a rear cover plate 4 is attached by soldering or other convenient means. It has a central hole 4a defined in a frusto-conical annular raised portion 4b of greater thickness.
- a pair of symmetrical wing projections 5 are provided on an inside surface of the rear cover plate 4 . They are generally rectangular with arcuate radially outer walls. Their inner limits are adjacent the hole 4a.
- Fig. 7 shows a convenient spring clip 7 for the present embodiment.
- This clip 7 has a generally "spectacle frame” shape. It is made of a resilient material,such as metal wire. It has side legs 7a,7a generally symmetrically formed in U-shapeswith free inner arms bent inwardly. The outer arms are connected by an upper rim having an arcuate dent or bridge portion 7c downwardly. This is also inclined outwardly. In other words, a plane including said arcuate dent 7c and the plane containing the side legs 7a,7a are at an angle.
- This spring clip 7 is inserted with its arcuate dent 7c in the space beneath the bent over arm of either one of the L-shape pieces 6, and with its side legs 7a embracing the wings 5,5.
- Each of its inner arms has a free end portion 7b located between a respective wing projection 5 and the nearer side of the two L-shape pieces 6,6 so as to sandwich both ends of one of the L-shape pieces 6 at its tip ends.
- the free arms 7b,7b are retained in a resiliently deformed state, being urged towards one another.
- a securing plate 8 is fixed onto the inside of the rear cover plate 4 after the securing of the spring clip 7.
- This securing plate 8 is generally rectangular in shape and has toward the casing shell 3 a central frusto-conical annular projection 8a, which has a central reverse projection having the general form of a cylinder 8b with a semi-spherical tip end toward the rear cover plate 4.
- the frusto-conical projection 8a has its root diameter generally identical with the diameter of the annular hole 4a of the plate 4, and their axes coincide.
- the plate 8 has its length identical with the horizontal distance between the ends of the two L-shaped pieces 6,6. Its lateral dimension is shorter than said distance.
- the securing plate 8 is fixed to the plate 4 by inserting screws 9 into upper and lower holes 8c, 8c in the lengthwise direction and threadably mating said screws 9 within the threaded holes 6b,6b.
- the plate 8 is fixed so that the tip end of cylinder 8b extends into an axial central portion of the hole 4a.
- the shank element 2 has a structure as shown in Figs. 10 and 11, which comprises a keeper 10 having a recess 10a for hiding a button in the shirt's sleeve cuff, and a shank 11 integrally provided at one end thereof, extending from its inner side on the same side of the recess 10a, at an angle so as to form a generally V-shape angle therebetween, as shown in Fig. 10.
- the shank 11 has at its tip end a semi-spherical head end portion 12 whose central forward end has an orifice 12a for receiving said cylinder 8b.
- an orifice 12a for receiving said cylinder 8b.
- opposed slots or grooves 12b,12b are provided at both sides of the orifice 12a.
- Each slit has a bottom wall which is parallel with the axis of the shank 11, and the upper and lower side faces are perpendicular to the axis. The slits are dimensioned for receiving the free end portions 7b of the spring clip 7.
- the head 12 is formed semi-spherically but its circular curved face continues from a position generally identical with the side rim of the button keeper 10 side of said slots 12b.
- the root of the head has a plane surface perpendicular to the axis of the shank 11 and a smaller diameter arm continues therefrom to the shank 11.
- This arm 11 a has a smaller diameter than the shank 11 and a length slightly larger than the thickness of the cloth of the sleeve cuff of the shirt.
- the shank 11 is inserted into the button holes of the cuff of the wearer's sleeve and the link's head 12 is brought on the surface of the cuff.
- the head 12 is inserted into the circular hole 4a of the decorative head element 1, keeping the slots 12b,12b of the head 12 parallel to the free end portions 7b,7b of the clip spring 7.
- the clip's free end portions 7b,7b are forcibly spread along the semi-spherical surface of the head 12 and pushed upwardly, as shown in Fig. 12, and upon oppositely facing the slots 12b and the free end portions 7b, the free end portions 7b come into the slots 12b by their own repulsive stored energy and the cylinder 8b is snugly received in the orifice 12a.
- the clip free end portions 7b,7b are resiliently urged to approach one another and also to push the shank element 2 out. Since the head's semi-spherical surface starts at a position corresponding with the side rim of the button keeper 10 side, the clip free end portions 7b slides along the head's semi-spherical surface and the head 12 is thereby pushed out from the annular hole 4a to permit an easy de-coupling of the shank element 2. After that, the clip free end portions 7b,7b take positions between the wings 5 and the L-shaped pieces 6. Thus, the assembling and the disassembling and attaching and detaching of the cufflink are easily effectable at a desired time.
- the embodiment has been explained for use for the convertible sleeve cuff having button thereon which is hidden within the recess 10a of the keeper 10 but the cufflink is also compatibly usable for the conventional double cuff.
- the decorative head can be decorated with a fanciful design, symbol or symbols or alphabets such as initials of the wearer's name, a house or family mark or a club's mark and the like. Those can be engraved on the decorating surface or attached with a metallic sticker having those decorative signs with a certain adhesive. Such stickers can be chosen by the wearer.
- Fig. 19 shows a link member usable in place of the shank element 2 described above. It has a shank 11 formed in annular ring shape having its central hole 11 b to prevent the link from rotating. Its shape is largely arbitrary and much variation is possible, provided that it can fulfil its function.
- Figs. 20-36 show another embodiment of the invention. Elements which generally correspond bear the same reference numerals as used in Figs. 1 to 19.
- a decorative head element 1 is formed generally as a quadrilateral enclosure.
- the element 1 is freely dis-assemblably assembled with a shank and shank element 2 formed separately therefrom.
- the decorative head element 1 has a generally rectangular casing shell 3 formed from (e.g. noble metal. It is open to tha rear, where a generally rectangular cover plate 4 is secured e.g. by soldering.
- the plate 4 has a central circular hole 4a surrounded by a raised portion 4b which builds up slowly toward the circular hole 4a at the outside surface of the plate 4.
- a low side wall 4d extends at the inside periphery of the cover plate 4 and a central band or wall 4e extends transversely across the inner surface of the plate 4.
- a lower step 4f is formed outside the side wall 4d throughout the entire circumference thereof, for use in fitting to the casing shell 3.
- the central wall 4e is formed as high as the side wall 4d so as to close the above circular hole 4a. Its portion confronting the circular hole 4a is thin. This portion is dished inwardly, the dishing 4g protruding towards the casing 3. At the opposite side of the dishing 4g, there is a boss 4h of bullet head shape, projecting into the hole 4a. Its height is such that it does not project outside the hole 4a.
- a slot 4i having a depth equal to the height of the central wall 4e is formed across the wall 4e adjacent one side of the dishing 4g, so as to divide the wall 4e into two parts.
- a pilot hole 4j of small diameter extends through the side wall 4d and the central wall 4e on both sides of the slot 4i, into the region of the dishing 4g.
- a pin 105 fits therein.
- a pair of rectangular projections 4k are provided, one on either side of the central wall 4e" at the rear side of the cover plate 4. Their inner edges are in line with the circumference of the circular hole 4a. They are spaced from the central wall 4e by approximately the diameter of a fine metal wire which constitutes a spring as described below.
- the above slot 4i is used to install a spring clip 7 of "spectacle frame” configuration, formed from a piece of fine metal wire of sufficient resilience as shown in Fig. 26.
- the spring 7 has generally U-shaped side leg portions 7a,7a located side by side, the inner leg portions being straight free end portions 7b.
- the outer leg portions are connected at their upper ends by a portion comprising an arcuated dent 7c formed so as to curve toward the free end portions 7b but out of the plane, towards the outside.
- the spring 7 is installed in position by fitting the dent 7c into the slot 4i, defoming resiliently by depressing the curved portion using a fine jig so that the plane containing the dent 7c and the plane containing the leg portions 7a, come together.
- the pin 105 is passed into the pilot hole 4j so that it crosses the slot 4i and passes over the dent 7c.
- each free end portion 7b is positioned between a projection 4k and the central wall 4e, one on each side of the hole 4a.
- the dent 7c is forcibly deflected so that the spring 7 is given a force urging the leg portions 7a to the rear side of the plate 4.
- the shank element 2 on shank and keeper unit, is shown in Fig. 28 and 29. It includes a button keeper 10 having a circular recess 10a to receive a button and a shank 11 formed integrally therewith at one end thereof and tilted toward the recess 10a. Accordingly, when looked at from the side, as in Fig. 28, the shank element 2 has a V-shape.
- a semi-spherical head 12 is formed on the tip end portion of the shank 11, and a pilot hole 12a to be fitted by the boss 4h is formed at the centre of the tip end of the head 12. Also there is a slot 12b, on each side of the head 12, perpendicular to the axial line of the shank 11.
- the slots have such a width and depth as to be capable of holding respective free end portions 7b of the spring clip 7.
- the head 12 is formed semi-spherically so that a circular curved surface starts in continuity from approximately the same position as the button keeper 10-side edge of the above slot 12b.
- a shaft 11 a of a small diameter is connected to this base portion.
- the shaft 11a a is smaller in diameter than the shank 11 and its length is slightly larger than the thickness of a shirt cloth.
- the shank element 2 is passed-through the. button holes of a shift cuff from inside to outside with the two ends of the cuff overlapped, so that the head 12 is disposed at the front-side of the cuff. While thus disposed, the head 12 is fitted into the circular hole 4a of the decorative head element 1 so that the slots 12b, of the head 1-2 confront respective free end portions 7b, of the spring 7. This is shown in Fig. 30. As indicated in the view, a proper fitting can be obtained by fitting the shank 11 into the circular hole 4a with the direction in which the button keeper 10 projects relative to the shank 11 crossing perpendicularly the longitudinal direction of the casing shell 3 of the decorative head element 1. The head 12 is further pushed to travel under this condition.
- the free end portions 7b push back the shank element 2 with the free end portions 7b within the slots 12b, urged towards the plate 4 so that the head 12 returns together with the free end portions 7b to the original position relative to the free end portions 7b in the circular hole 4a.
- the free ends 7b are perfectly fitted in the slots 12b.
- the head 12 is not prevented from returning into the circular hole 4a, the free ends 7b do not slip out of the slots 12b and the member 2 does not slip out of the decorative head element 1.
- the decorative head element 1 will not turn so as to slip out of the mating unit because the free end portions 7b are restrained by the sides walls of the projections 4k adjacent the hole 4a.
- the decorative head element 1 When it is desired to remove the cufflink, the decorative head element 1 is depressed relative to shank element 2 so that the free end portions 7b are pushed towards the casing shell 3-side so that they no longer abut the side walls of the projections 4k. Rotation through 90° in either direction then frees the ends 7b from the slots 12b so that they contact the circular peripheral surface of the head 12 and are moved onto the upper surfaces of the projections 4k,4k. This condition is shown in Fig. 33.
- the free end portions 7b experience resilient forces, that firstly urge them together and secondly urged them to push out the shank element 2. Since the curved surface of the head 12 starts approximately from the same position as that edge of slot 12b which is on the side of the button keeper 10-side edge of the slot 12b, the free end portions 7b slide along the curved surface of the head 12. As a result of this, as shown in Fig. 35, the head 12 is pushed out from the circular hole 4a to effect a simple removal of the link member 2. The free end portions 7b are then located each between the projection 4k and the central wall 4e. Installation and removal of the cufflink are executed very easily in this manner. As is apparent from the description set forth so far, the plate 4 can be integrally formed.

Description
- The present invention relates to cufflinks.
- Conventional cufflinks are one-piece, comprising a decorative element and a link member integrally provided therewith. The link member bears an engaging element rotatable in an axial plane. This engaging element has to be inserted through the button holes of a shirt cuff, keeping it in a straight line, and then to be rotated so as to securely attach the link to the cuff.
- The use of such cufflinks has a drawback that the insertion of the link into the button holes provided at a rear portion of the cuff need an inconvenient manipulation since the link is integral with the decorative member. Moreover the link is easily rotated by contact with the wearer's clothing and the other objects. Such factors tend to cause an untidy appearance. The link may fall from the cuff, which often disappears from view. A convertible cuff shirt is commonly worn with the conventional cufflink. This has buttons near the cuff button holes. The conventional cufflink as described above does not conceal the buttons, and thus an untidy appearance results.
- The present applicant has proposed several improvements to ameliorate such drawbacks, and has obtained the issued Utility Model Nos. 1253159, 1253166 and 1253167 on October 31, 1978 in Japan.
- The inventor has further proposed an improved cufflink described in Japanese Utility Model Application Ser. No. 54-49013 (corresponding to US Patent No. 4242776). This may be summarized as follows:
- The cufflink has two units which are dis- assemblably assembled to one another through a pair of shirt cuff button holes. For assembly the outer end of the shank is inserted through an opening in the back of the decorative head element, and pushed in further to deflect two springs inside the decorative head element. The decorative head element is then released, to lock the cufflink in an assembled condition. The shank is unitary with a keeper which has a recess in its inner face, for accepting and hiding from view the shirt button found beside one of the cuffbutton holes on so called "convertible cuff shirts". For removal, the head and keeper are pushed together and then relatively turned 90 degrees about the shank axis.
- For the above US application, the US Patents 506778, 644894, 885419, 908745, 2745620, 3107409 3220073, 3643296 and 3718950 were cited, but only for reference.
- For its further corresponding applications in West Germany (under Ser. P2937344.2-23) and French patent application 79-27302, prior art has been cited as follows:
- The present applicant's prior Japanese Pub. No. 53-3856 (corr. to said Japanese U.M. 1253166), US Patents 1515997, French Patents 533883 and 701467, German 701467, 551971, US Patents 1431339, 2406026, 2658249, 2847744, French Patent 478722 and German 225466.
- However, these documents are of little relevance to the invention against which they were cited, and of still less to the present invention.
- The present invention has been made to ameliorate still further said prior drawbacks. Preferred embodiments provide a cufflink which permits easy assembly and fixing through the button holes of a cuff, readily effectable with one hand. Furthermore, the construction and manufacture of the links may be much simpler than those of the links just described. Thus, the number of separate components may be reduced, and the troublesome operation of securing small components with tiny screws may be avoided.
- According to the present invention there is provided a cufflink comprising a releasably interconnectable head element and shank element, wherein the head element includes a rear wall portion having an aperture (4a) into which a head end portion of the shank element is insertable, there being spring clip engagement means for releasably retaining the inserted shank head end portion, said engagement means comprising a spring clip having a pair of laterally spaced, generally U-shaped legs having respective free end portions nearest one another and having respective opposite ends joined by a rim, said free end portions being normally urged to lie adjacent said aperture at respective sides thereof so as to restrain inward passage of the shank element; said rim, in the vicinity of said free end portions having an arcuate bridge portion; all of said spring clip except said bridge portion lying generally in a common plane, and said bridge portion being resiliently urged to be at an acute angle which intersects said common plane, and said rear wall portion including means for engaging said bridge of said spring clip to the head element with said rim resiliently torsionally stressed by an amount sufficient to cause said bridge portion to lie substantially in said common plane, whereby said spring clip is resiliently loaded against the inside face of said rear wall portion; there also being abutment means at diametrically opposide sides of the aperture which restrain deflection of the free end portions of the spring clip laterally apart when they are adjacent the rear wall portion; the head end portion of the shank element being convexly curved and provided with a diametrically opposed pair of grooves, such that when the head portion is thrust into the aperture it first deflects the free end portions of the spring clip away from the inside face of the rear wall portion beyond the abutment means and then laterally away from one another, until they snap into engagement with respective ones of said grooves, whereafter the spring urges the head end portion outwardly until the end portions of the clip are adjacent the wall portion; the arrangement being such that disengagement of the shank element requires it to be rotated by substantially 90° to disengage the free end portions from the grooves, but this is prevented by the abutment means until the shank element has been pushed inwardly against the urging of the spring clip.

- The first embodiment (shown in Figs. 1 to 18) has a
head element 1. This has acasing shell 3 whose general form is that of a rectangular box with an open back. A separateengaging shank element 2 is disassemblably attached, so as to form a cufflink. - The
casing shell 3 may comprise a precious metal. Arear cover plate 4 is attached by soldering or other convenient means. It has acentral hole 4a defined in a frusto-conical annular raisedportion 4b of greater thickness. - Provided on an inside surface of the
rear cover plate 4 is a pair ofsymmetrical wing projections 5 at diametrically opposed sides of saidhole 4a. They are generally rectangular with arcuate radially outer walls. Their inner limits are adjacent thehole 4a. - Also on the inner surface of the
rear cover plate 4 and in a widthwise direction at the top and the bottom of the hole circumference, sandwiching thehole 4a are a pair of L-shaped pieces arcuate walls 6a which continue thecircular hole 4a. The bent-over portions are provided with screw threadedholes 6b. The construction and arrangement of theelements - Fig. 7 shows a
convenient spring clip 7 for the present embodiment. Thisclip 7 has a generally "spectacle frame" shape. It is made of a resilient material,such as metal wire. It hasside legs bridge portion 7c downwardly. This is also inclined outwardly. In other words, a plane including saidarcuate dent 7c and the plane containing theside legs - This
spring clip 7 is inserted with itsarcuate dent 7c in the space beneath the bent over arm of either one of the L-shape pieces 6, and with itsside legs 7a embracing thewings free end portion 7b located between arespective wing projection 5 and the nearer side of the two L-shape pieces shape pieces 6 at its tip ends. Thefree arms - The gaps between the bent over arms of the L-
shape pieces 6 and the inner face of thecover plate 4 are similar to the spring clip diameter. Therefore thearcuate dent 7c must be resiliently deformed on insertion between the L-shapedpiece 6 and therear cover plate 4. Thus, theside legs plate 4. - A securing
plate 8 is fixed onto the inside of therear cover plate 4 after the securing of thespring clip 7. This securingplate 8 is generally rectangular in shape and has toward the casing shell 3 a central frusto-conicalannular projection 8a, which has a central reverse projection having the general form of acylinder 8b with a semi-spherical tip end toward therear cover plate 4. The frusto-conical projection 8a has its root diameter generally identical with the diameter of theannular hole 4a of theplate 4, and their axes coincide. - The
plate 8 has its length identical with the horizontal distance between the ends of the two L-shapedpieces plate 8 is fixed to theplate 4 by insertingscrews 9 into upper andlower holes screws 9 within the threadedholes plate 8 is fixed so that the tip end ofcylinder 8b extends into an axial central portion of thehole 4a. - The
shank element 2 has a structure as shown in Figs. 10 and 11, which comprises akeeper 10 having arecess 10a for hiding a button in the shirt's sleeve cuff, and ashank 11 integrally provided at one end thereof, extending from its inner side on the same side of therecess 10a, at an angle so as to form a generally V-shape angle therebetween, as shown in Fig. 10. - The
shank 11 has at its tip end a semi-sphericalhead end portion 12 whose central forward end has anorifice 12a for receiving saidcylinder 8b. Provided at both sides of theorifice 12a are opposed slots orgrooves shank 11, and the upper and lower side faces are perpendicular to the axis. The slits are dimensioned for receiving thefree end portions 7b of thespring clip 7. - The
head 12 is formed semi-spherically but its circular curved face continues from a position generally identical with the side rim of thebutton keeper 10 side of saidslots 12b. The root of the head has a plane surface perpendicular to the axis of theshank 11 and a smaller diameter arm continues therefrom to theshank 11. Thisarm 11 a has a smaller diameter than theshank 11 and a length slightly larger than the thickness of the cloth of the sleeve cuff of the shirt. - Now, installation/assembly and removal/ disassembly of the cufflink on and from a shirt cuff will be explained in more detail.
- First, for wearing, the
shank 11 is inserted into the button holes of the cuff of the wearer's sleeve and the link'shead 12 is brought on the surface of the cuff. In this state, thehead 12 is inserted into thecircular hole 4a of thedecorative head element 1, keeping theslots head 12 parallel to thefree end portions clip spring 7. - The clip's
free end portions head 12 and pushed upwardly, as shown in Fig. 12, and upon oppositely facing theslots 12b and thefree end portions 7b, thefree end portions 7b come into theslots 12b by their own repulsive stored energy and thecylinder 8b is snugly received in theorifice 12a. - This state is shown in Fig. 13. In this state, release of the pressure on the
shank element 2 allows it to be pushed back, the clipfree end portions 7b remaining snugly within theslots 12b, because of their resilient urging toward therear cover plate 4. Then thehead 12 returns to its original position of the clip'sfree end portions 7b, together with saidfree end portions 7b. In this state, since thefree end portions 7b are completely within theslots 12b, they do not prevent the head from returning into thehole 4a and the clipfree end portions 7b never slip off nor come out from theslots 12b and theshank element 2 never slips nor comes out from thedecorative head element 1. This means that thedecorative head element 1 never rotates nor drops unless it is pushed or compressed toward theshank element 2, since the clipfree end portions 7b are blocked to move with the circumferential wall of theannular hole 4a. This locking operation can be effected using one finger. - For detaching the cufflink, one must push the
decorative member 1 toward theshank element 2 to pull the clipfree end portions 7b out from theannular hole 4a and then rotate the head in either direction for 90° with respect to thelink 2 from the state shown in Fig. 13 to the state shown in Fig. 15. Then, the clipfree end portions slots head 12. - In this state, the clip
free end portions shank element 2 out. Since the head's semi-spherical surface starts at a position corresponding with the side rim of thebutton keeper 10 side, the clipfree end portions 7b slides along the head's semi-spherical surface and thehead 12 is thereby pushed out from theannular hole 4a to permit an easy de-coupling of theshank element 2. After that, the clipfree end portions wings 5 and the L-shapedpieces 6. Thus, the assembling and the disassembling and attaching and detaching of the cufflink are easily effectable at a desired time. - Heretofore, the embodiment has been explained for use for the convertible sleeve cuff having button thereon which is hidden within the
recess 10a of thekeeper 10 but the cufflink is also compatibly usable for the conventional double cuff. The decorative head can be decorated with a fanciful design, symbol or symbols or alphabets such as initials of the wearer's name, a house or family mark or a club's mark and the like. Those can be engraved on the decorating surface or attached with a metallic sticker having those decorative signs with a certain adhesive. Such stickers can be chosen by the wearer. - Fig. 19 shows a link member usable in place of the
shank element 2 described above. It has ashank 11 formed in annular ring shape having its central hole 11 b to prevent the link from rotating. Its shape is largely arbitrary and much variation is possible, provided that it can fulfil its function. Figs. 20-36 show another embodiment of the invention. Elements which generally correspond bear the same reference numerals as used in Figs. 1 to 19. - A
decorative head element 1 is formed generally as a quadrilateral enclosure. Theelement 1 is freely dis-assemblably assembled with a shank andshank element 2 formed separately therefrom. - The
decorative head element 1 has a generallyrectangular casing shell 3 formed from (e.g. noble metal. It is open to tha rear, where a generallyrectangular cover plate 4 is secured e.g. by soldering. Theplate 4 has a centralcircular hole 4a surrounded by a raisedportion 4b which builds up slowly toward thecircular hole 4a at the outside surface of theplate 4. - A pair of
elongate openings plate 4, is formed at each longitudinal end region of theplate 4. They lessen the weight of thecover plate 4 and let out any water, etc. which might enter the interior. - A
low side wall 4d extends at the inside periphery of thecover plate 4 and a central band orwall 4e extends transversely across the inner surface of theplate 4. Alower step 4f is formed outside theside wall 4d throughout the entire circumference thereof, for use in fitting to thecasing shell 3. - The
central wall 4e is formed as high as theside wall 4d so as to close the abovecircular hole 4a. Its portion confronting thecircular hole 4a is thin. This portion is dished inwardly, the dishing 4g protruding towards thecasing 3. At the opposite side of the dishing 4g, there is aboss 4h of bullet head shape, projecting into thehole 4a. Its height is such that it does not project outside thehole 4a. - A
slot 4i having a depth equal to the height of thecentral wall 4e is formed across thewall 4e adjacent one side of the dishing 4g, so as to divide thewall 4e into two parts. - A
pilot hole 4j of small diameter extends through theside wall 4d and thecentral wall 4e on both sides of theslot 4i, into the region of the dishing 4g. Apin 105 fits therein. - A pair of
rectangular projections 4k are provided, one on either side of thecentral wall 4e" at the rear side of thecover plate 4. Their inner edges are in line with the circumference of thecircular hole 4a. They are spaced from thecentral wall 4e by approximately the diameter of a fine metal wire which constitutes a spring as described below. - The
above slot 4i is used to install aspring clip 7 of "spectacle frame" configuration, formed from a piece of fine metal wire of sufficient resilience as shown in Fig. 26. Thespring 7 has generally U-shapedside leg portions free end portions 7b. The outer leg portions are connected at their upper ends by a portion comprising anarcuated dent 7c formed so as to curve toward thefree end portions 7b but out of the plane, towards the outside. - The
spring 7 is installed in position by fitting thedent 7c into theslot 4i, defoming resiliently by depressing the curved portion using a fine jig so that the plane containing thedent 7c and the plane containing theleg portions 7a, come together. In this condition thepin 105 is passed into thepilot hole 4j so that it crosses theslot 4i and passes over thedent 7c. Then, eachfree end portion 7b is positioned between aprojection 4k and thecentral wall 4e, one on each side of thehole 4a. Thus thedent 7c is forcibly deflected so that thespring 7 is given a force urging theleg portions 7a to the rear side of theplate 4. - The
shank element 2, on shank and keeper unit, is shown in Fig. 28 and 29. It includes abutton keeper 10 having acircular recess 10a to receive a button and ashank 11 formed integrally therewith at one end thereof and tilted toward therecess 10a. Accordingly, when looked at from the side, as in Fig. 28, theshank element 2 has a V-shape. - A
semi-spherical head 12 is formed on the tip end portion of theshank 11, and apilot hole 12a to be fitted by theboss 4h is formed at the centre of the tip end of thehead 12. Also there is aslot 12b, on each side of thehead 12, perpendicular to the axial line of theshank 11. The slots have such a width and depth as to be capable of holding respectivefree end portions 7b of thespring clip 7. - Furthermore, the
head 12 is formed semi-spherically so that a circular curved surface starts in continuity from approximately the same position as the button keeper 10-side edge of theabove slot 12b. - At the base of the
head 12 is a flat surface perpendicular to the axial line of theshank 11, and ashaft 11 a of a small diameter is connected to this base portion. Theshaft 11a a is smaller in diameter than theshank 11 and its length is slightly larger than the thickness of a shirt cloth. - Next, there will be described how to use the cufflink just described.
- First, when installing, the
shank element 2 is passed-through the. button holes of a shift cuff from inside to outside with the two ends of the cuff overlapped, so that thehead 12 is disposed at the front-side of the cuff. While thus disposed, thehead 12 is fitted into thecircular hole 4a of thedecorative head element 1 so that theslots 12b, of the head 1-2 confront respectivefree end portions 7b, of thespring 7. This is shown in Fig. 30. As indicated in the view, a proper fitting can be obtained by fitting theshank 11 into thecircular hole 4a with the direction in which thebutton keeper 10 projects relative to theshank 11 crossing perpendicularly the longitudinal direction of thecasing shell 3 of thedecorative head element 1. Thehead 12 is further pushed to travel under this condition. Then, as shown in Figs. 30 and 31, thefree end portions 7b of thespring 7 are separated further from each other and pushed upward.along the curved surface of thesemi-spherical head 12. When thefree end portions 7b confronts theslot 12b, it is urged therein by--its resilient, and theboss 4b is fitted into theorifice 12a. This is shown in Fig. 31. - When the inserting force is released, the
free end portions 7b push back theshank element 2 with thefree end portions 7b within theslots 12b, urged towards theplate 4 so that thehead 12 returns together with thefree end portions 7b to the original position relative to thefree end portions 7b in thecircular hole 4a. The free ends 7b are perfectly fitted in theslots 12b. As a result, thehead 12 is not prevented from returning into thecircular hole 4a, the free ends 7b do not slip out of theslots 12b and themember 2 does not slip out of thedecorative head element 1. In other words, unless deliberately pushed toward theshank element 2, thedecorative head element 1 will not turn so as to slip out of the mating unit because thefree end portions 7b are restrained by the sides walls of theprojections 4k adjacent thehole 4a. - When it is desired to remove the cufflink, the
decorative head element 1 is depressed relative toshank element 2 so that thefree end portions 7b are pushed towards the casing shell 3-side so that they no longer abut the side walls of theprojections 4k. Rotation through 90° in either direction then frees theends 7b from theslots 12b so that they contact the circular peripheral surface of thehead 12 and are moved onto the upper surfaces of theprojections - The
free end portions 7b experience resilient forces, that firstly urge them together and secondly urged them to push out theshank element 2. Since the curved surface of thehead 12 starts approximately from the same position as that edge ofslot 12b which is on the side of the button keeper 10-side edge of theslot 12b, thefree end portions 7b slide along the curved surface of thehead 12. As a result of this, as shown in Fig. 35, thehead 12 is pushed out from thecircular hole 4a to effect a simple removal of thelink member 2. Thefree end portions 7b are then located each between theprojection 4k and thecentral wall 4e. Installation and removal of the cufflink are executed very easily in this manner. As is apparent from the description set forth so far, theplate 4 can be integrally formed.
