Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an accessory having a retaining mechanism for easily and surely holding a pin used for attaching a broach or other accessories to clothes or the like.

[0002]

[Prior art]

 Conventionally, various devices have been proposed for easily and surely holding an accessory such as a broach. However, for gold and silver brooches, the brazing temperature of gold and silver is around 700 ° C, so that a built-in spring cannot be used and simplicity is required. Only two types of fasteners are actually used, called what are called gun-types.

[0003] The windmill type is provided with a locking member that rotates like a windmill and locks the pin on the side where the pin is stopped (generally called a catch). On the other hand, the so-called gun type has a structure similar to that described in JP-A-7-222609.

The present invention is an improvement of a structure called a gun type. Hereinafter, a retaining mechanism disclosed in Japanese Patent Application Laid-Open No. 7-222609 will be briefly described with reference to FIGS. 21 and 22. The names of the component parts shall be those described in the official gazette. The metal fitting of this accessory is composed of a pin 71 and a retaining mechanism 74. The pin 71 is swingably attached to the accessory main body via the support post 72 and the bearing 73, and the retaining mechanism 74 is attached to a position where the pin 71 can be detached.

As shown in FIGS. 21 and 22, this retaining mechanism 74 called a catch inserts a cylindrical holding member 76 into a cylindrical case member 75 and pushes a holding pin 77 in a radial direction of the cylindrical case member 75. After passing through the slide groove 81 of the cylindrical holding member 76 and fixing the holding pin 77, the tip of the elastic piece 79 of the figure 78 of the spring 78 is pinched. And formed.

Here, insertion and locking of the pin 71 are performed as follows. That is, as shown in FIG. 21A, the cylindrical holding member 76 is slid in the direction in which the cylindrical holding member 76 is pulled out from the cylindrical case member 75, and the pin 71 is inserted through the notch 83 of the cylindrical case member 75. Put in. Then, holding the knob 82 of the cylindrical holding member 76, the cylindrical holding member 76 is pushed into the cylindrical case member 75, and the notch 83 is covered with the cylindrical holding member 76 so that the pin 71 does not come off. I do.

At this time, the cylindrical holding member 76 is pushed from the inside by the elastic force of the elastic piece 79 of the spring 78, and the frictional force between the cylindrical holding member 76 and the cylindrical case member 75 increases, The holding member 76 does not slide without permission. When the cylindrical holding member 76 is further pushed in, as shown in FIG. 21B, the tip of the elastic piece 79 in the shape of an eight character engages with a step formed inside the knob 82 of the cylindrical holding member 76, The cylindrical holding member 76 is fixed inside the cylindrical case member 75. As described above, in the metal fastener of the accessory, the step formed at the end of the spring 78 (the eight-piece elastic piece 79) and the end of the cylindrical holding member 76 is the main part of the retaining mechanism.

[0008]

[Problems to be solved by the invention]

 Fasteners called windmills are extremely simple in mechanism and easy to assemble, and can be inexpensive. For this reason, it is often used in silver brooches. However, in this type of fastener, since the pinwheel is simply rotated at the position where the pin is to be locked, the pin is disengaged with a slight force and the broach is eliminated. The danger of losing is extremely high.

[0009] The metal fastener of the gun type disclosed in Japanese Patent Application Laid-Open No. Hei 7-222609 described above has the advantage that the pin 71 is securely locked by the use of the spring 78, and that the high quality and assembly cost are high. As a result, it is often used in high priced gold brooches. However, it is necessary to incorporate the retaining pin 77 and the spring 78 after brazing the retaining mechanism 74 to the broach, which requires time and skill in assembling.

Further, the retaining mechanism 74 has two slide grooves 81 for passing the holding pins 77 through the cylindrical holding member 76, and the cylindrical holding member 76 is deformed by the structure and the elastic force of the spring 78. There is a problem that is easy to do. When the cylindrical holding member 76 is deformed, the frictional force between the cylindrical holding member 76 and the cylindrical case member 75 increases, which causes a reduction in movement and an unpleasant operation sound.

Further, the cylindrical case member 75 needs to be provided with a small hole through which the holding pin 77 passes, and the cylindrical holding member 76 also needs to be formed with a slide groove 81 and the like, which makes the manufacturing complicated. This increases the number of steps and increases the cost. In addition, when fixing the holding pin 77 to the cylindrical case member 75 by caulking or the like, extreme care is required to prevent the cylindrical case member 75 and the cylindrical holding member 76 from being deformed, and the assembly is difficult. It takes time.

An object of the present invention is to provide an ornament which has a simple configuration, has a small number of manufacturing steps, is low in cost, and has good operability and reliable pin locking.

[0022]

[Embodiment of the invention]

 Hereinafter, an accessory according to an embodiment of the present invention will be described with reference to FIGS. First, the first embodiment will be described with reference to FIGS.

FIG. 1 shows the overall configuration of the accessory 1. The accessory 1 has a gold design part 2 disposed on the front side. A pin 4 is provided on the back side of the main body of the accessory 1 through a brazed pin fixing member 3, and a retaining mechanism 5 is attached by brazing.

The pin 4 is attached to the pin fixing member 3 so as to swing freely. The retaining mechanism 5 is mounted at a predetermined distance from the mounting position of the pin 4 and has a structure for holding the tip of the pin 4. Here, the accessory 1 is formed of gold or silver, but may be another material. It is to be noted that a fastener for attaching the pin 4 and the retaining mechanism 5 may be provided on the back side of the main body of the accessory 1, and another ornament such as a broach may be attached on the front side of the fastener.

As shown in FIGS. 2 and 3, the retaining mechanism 5 includes a cylindrical tubular member 10 and a rod member 11 having a circular cross section.

The cylindrical member 10 has a through hole 12 passing through the center thereof in the axial direction, a V-shaped notch 13 for inserting the pin 4 into the through hole 12 from the lateral direction, and brazing to the back surface of the accessory 1. A base portion 14 for mounting by a step, a first groove portion 15 serving as a locking portion provided on the outer peripheral surface of the through hole 12, and a rod member 11 positioned at a position for holding the pin 4. 16 and has a cylindrical shape. Both grooves 15 and 16 are formed in a quadrangular cross section so that the rod member 11 does not easily come off. In this embodiment, the cylindrical member 10 is composed of metal half-cylindrical members 20 and 21 that are divided into two right and left parts when viewed from the front of the through hole 12. The half-cylinder members 20 and 21 are formed by forging or casting such as a lost wax method or a powder molding method.

One half-cylinder member 20 has a semicircular concave portion 12 a that forms half of the through hole, a half base portion 14 a that forms half of the base portion 14, and a half of the first groove portion 15. A first groove recess 15a to be formed, a second groove recess 16a constituting half of the second groove 16, and an engagement projection 22 for integrating the two half-cylinder members 20, 21 are provided. . The other half-cylinder member 21 has a semicircular concave portion 12 b that forms half of the through hole 12, a notch 13, a half base portion 14 b that forms half of the base portion 14, A first groove recess 15b that forms half of the groove 15, a second groove recess 16b that forms half of the second groove 16, and an engagement recess 23 into which the engagement protrusion 22 fits are provided. ing.

The details of the outer peripheral surface of the through hole 12, in other words, the inner peripheral surface of the cylindrical member 10 are as shown in FIG. That is, the diameter Φ1 on the side where the rod member 11 is inserted and the diameter Φ2 on the opposite side are the same. Further, the length L1 from the insertion port to the first groove 15 and the length L6 from the port on the opposite side to the second groove 16 are the same. Further, the width L2 of the first groove 15 and the width L5 of the second groove 16 are the same. In this embodiment, the diameters Φ1 and Φ2 are each about 1.4 mm, the lengths L1 and L6 are each 0.7 mm, and the lengths L2 and L5 are each 0.6 mm.

Further, between the first groove 15 and the second groove 16, a first slope 17 and a second slope 18 are provided. In addition, the length L3 of the first slope portion 17 is shorter than the length L4 of the second slope portion 18, and the inclination angle α1 of the first slope portion 17 is reduced by the inclination angle of the second slope portion 18. The angle is larger than α2. In this embodiment, the length L3 is 1.2 mm, the length L4 is 2.7 mm, the inclination angle α1 is 1.9 degrees, and the inclination angle α2 is 0.85 degrees.

Further, the intersection of the two slopes 17 and 18 is recessed inward by the length m1 with respect to the inner peripheral surface on the insertion side of the rod member 11 and the opposite side. Further, the inner steps of both the grooves 15, 16 are recessed by the lengths m2, m3. In addition, the steps m4 and m5 of the grooves 15 and 16 are the same and are larger than the steps m2 and m3. In this embodiment, the length m1 is 0.05 mm, the lengths m2 and m3 are 0.09 mm, and the lengths m4 and m5 are 0.19 mm. The length L7 of the notch 13 is set to 4.2 mm.

The step m1 is for facilitating the movement of the bar member 11 between the two groove portions 15 and 16, and the reason that the inclination angles α1 and α2 satisfy α1> α2 is that the bar member 11 is pulled out. This is because it is difficult to apply force when pulling out, so that it can be easily pulled out. The installation of the slopes 17 and 18 and the step m1 is a preferable structure, but is not always necessary. The numerical values of the diameter Φ1, Φ2, the lengths L1, L2, L3, L4, L5, L6, L7, the steps m1, m2, m3, m4, m5, and the inclination angles α1, α2 are merely examples. Other values can be adopted as appropriate.

When the two half-cylinder members 20 and 21 are fitted and integrated, as shown in FIG. 6, if a gap g 3 can be formed on the side opposite to the base portion 14, the diameter of the through hole 12 can be reduced. It is preferable that Φ1 and Φ2 can be adjusted. That is, when the insertion or sliding movement of the rod member 11 is too slow, a force is applied in a direction to close the gap g3. Thereby, the operational feeling of the rod member 11 and the cylindrical member 10 is optimized.

The engagement projection 22 and the engagement recess 23 are so sized that the two half-cylinder members 20, 21 cannot be easily detached by fitting the two parts. Then, when the base portion 14 is brazed, the brazing enters the boundary portion between the two half-cylinder members 20 and 21 to completely integrate the two half-cylinder members 20 and 21. The intrusion of the wax is stopped at the engagement concave portion 23, and is prevented from entering the through hole 12.

The rod member 11 communicates with the pin insertion hole 30 into which the pin 4 is inserted, and makes the portion of the pin insertion hole 30 elastic by reducing the outer diameter by the elasticity. Split grooves 31, 32, locking protrusion 33 locked in first groove 15 serving as a locking portion to prevent rod member 11 from coming off, and a knob for manually operating rod member 11. And has a bar shape to be fitted into the tubular member 10. The knob portion 34 has a larger diameter than the diameter of the cylindrical member 10 and the locking projection 33 so as to prevent the rod member 11 from penetrating the inside of the cylindrical member 10 and to easily pull out the rod member 11. Is easy to catch.

The bar member 11 is a kind of beryllium copper having beryllium and copper, contains silver and a little cobalt, and has a Vickers hardness of about 160 to 200. And it has become elastic by the heat treatment of 300-500 degreeC. This means that when the base part 14 is brazed, the part of the base part 14 is at about 700 ° C., while the part of the bar member 11 is at about 300 to 500 ° C. For this reason, when brazing, the portions of the split grooves 31 and 32 have moderate elasticity (= spring force). The hardness increases to about HV400 after the heat treatment. Most preferably, the heat treatment temperature is 400 ° C. ± 20 ° C.

In the rod member 11 of this embodiment, the width W of the split grooves 31 and 32 is smaller than the diameter Φ 11 of the pin insertion hole 30. The outer diameter Φ12 of the rod portion is slightly smaller than the diameters Φ1 and Φ2 of the through holes 12 of the cylindrical member 10. The outer diameter Φ13 of the locking projection 33 is slightly larger than the diameters Φ1 and Φ2. In this embodiment, the diameter Φ11 is 1 mm, the diameter Φ12 is 1.4 mm, and the diameter Φ13 is 1.6 mm.

The length L 11 of the rod member 11 excluding the knob 34 is the same as the entire length of the tubular member 10 (= L 1 + L 2 + L 3 + L 4 + L 5 + L 6). On the other hand, the length L12 from the tip to the locking projection 33 is made smaller than the length L6 of the cylindrical member 10, and the width L13 of the locking projection 33 is made smaller than the widths L2, L5 of the grooves 15,16. In this embodiment, the length L11 is 6.5 mm, the length L12 is 0.55 mm, and the width L13 is 0.4 mm. The width L14 of the knob 34 is 0.85 mm, the width L15 of the slope 35 of the knob 34 is 0.2 mm, and the length L16 of the split grooves 31 and 32 is 3 mm. Further, the inclination angle β1 of the slope portion 35 of the knob portion 34 is set to 20 degrees.

Since the respective lengths of the rod members 11 are set as described above, in the state where the locking projections 33 enter the second groove portions 16 and further insertion is prevented, as shown in FIG. A gap g1 is formed between the member 10 and the knob 34. In this embodiment, the gap g1 is 0.15 mm, and the gap g2 obtained by adding the width L15 of the slope portion 35 to the gap g1 is 0.35 mm. These gaps g1 and g2 are spaces where a finger or a fingernail can enter when the bar member 11 is pulled out to the state shown in FIG.

Next, the assembly of the retaining mechanism 5 and the accessory 1 will be described.

First, the engagement protrusion 22 of the half-cylinder member 20 is fitted into the engagement recess 23 of the half-cylinder member 21 to be integrated. After that, the cylindrical member 10 and the rod member 11 are plated with gold, silver, or the like. Then, the rod member 11 is inserted into the tubular member 10 to form an integral part. At this time, since the diameter Φ13 of the locking protrusion 33 is larger than the diameter Φ1 of the through hole 12 of the tubular member 10, the hole does not normally enter the through hole 12. However, due to the presence of the split grooves 31 and 32, the portion surrounding the pin insertion hole 30 becomes elastic, the diameter Φ13 of the locking projection 33 decreases, and the rod member 11 is inserted into the through-hole 12. Go.

When the locking projection 33 comes to a position facing the first groove 15, the locking projection 33 enters the first groove 15 by the elastic return force of the portion surrounding the pin insertion hole. When the rod member 11 is further pushed, the diameter Φ13 of the locking projection 33 is reduced again, and the rod member 11 is inserted. The locking projection 33 advances while abutting on the slope 17, and then abuts on the slope 18. The diameter Φ 13 of the locking projection 33 expands on the slope portion 18. Then, the locking projection 33 enters the second groove 16.

The assembler checks the sliding state of the bar member 11 and, when it is determined that the movement from one of the locking positions to the other locking position is too easy, the two half-cylinder members 20, An adjustment is performed to narrow the gap g3 at the tip of the 21 to an appropriate state.

Thereafter, the base portion 14 of the tubular member 10 is brazed and fixed to the main body of the accessory 1 or a metal fitting to which the accessory 1 is attached. At this time, the wax flows from the boundary between the contact surfaces of the half-cylinder members 20 and 21 toward the through-hole 12. Stopped at Also, due to the high temperature during brazing, the peripheral portions of the split grooves 31 and 32 of the rod member 11 have moderate elasticity.

Next, the operation of the accessory 1 having the retaining mechanism 5 will be described with reference to FIGS.

Here, FIG. 4 shows a state where the rod member 11 is pulled out from the cylindrical member 10. This state is a state in which the pin 4 can be inserted into the notch 13 of the tubular member 10 and corresponds to the state of FIG. At this time, the first groove 15 of the cylindrical member 10 and the locking projection 33 of the bar member 11 are opposed and engaged. In the state of FIG. 4, the pin 4 is inserted into the through hole 12 from the notch 13. Thereafter, the bar member 11 is pushed.

FIG. 5 shows a state where the rod member 11 is pushed into the cylindrical member 10. At this time, the pin 4 is prevented from entering the pin insertion hole 30 of the rod member 11 and jumping out of the notch 13. Since the width W of each of the split grooves 31 and 32 is smaller than the large-diameter portion of the portion other than the tip of the pin 4, the pin 4 does not protrude from the split grooves 31 and 32 and the pin insertion hole. It is held within 30. At this time, the second groove 16 of the cylindrical member 10 and the locking projection 33 of the rod member 11 face and engage with each other. When the bar member 11 is pushed in, the knob 34 of the bar member 11 faces the edge of the cylindrical member 10 via the gap g2.

When the pin 4 is removed, the reverse operation is performed. That is, the bar member 11 is pulled from the state of FIG. 5 to the state of FIG. The retaining mechanism 5 locks or removes the pin 4 by alternately repeating the state of FIG. 4 and the state of FIG. 5 as described above.

Next, the retaining mechanism 40 of the second embodiment used for the accessory 1 of the present invention will be described with reference to FIGS. 14 and 15. The retaining mechanism 40 is attached to the accessory 1 in the same manner as the retaining mechanism 5 of the first embodiment. The same members as those of the retaining mechanism 5 of the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted or simplified.

The retaining mechanism 40 includes a cylindrical member 10, a rod member 11, a ball 41 disposed between the two members 10, 11, and a spring for pressing the ball 41 toward the first groove 15. 42. The ball 41 and the spring 42 are arranged in an elongated hole 43 provided in the rod member 11. When the rod member 11 is rotated in the circumferential direction, the spheres 41 alternate between the first positioning grooves 44 and the second positioning grooves 45 provided at predetermined intervals in the circumferential direction in the first grooves 15. Is positioned.

The retaining mechanism 40 is used by inserting the rod member 11 into the cylindrical member 10 and in a state shown in FIG. The split groove 36 of the bar member 11 has a width that allows the pin 4 to enter and exit, and is different from the split grooves 31 and 32 of the first embodiment. In the state of FIG. 14, the notch 13 of the cylindrical member 10 faces the split groove 36, and the pin 4 passes through the notch 13 and the split groove 36 from the lateral direction and enters the pin insertion hole 30.

Thereafter, when the rod member 11 is rotated in the direction indicated by the arrow A in FIG. 15, the ball 41 escapes from the first positioning groove 44. At this time, the spring 42 is compressed. When the rod member 11 is rotated by 90 degrees, the ball 41 enters the second positioning groove 45, and the rod member 11 is positioned again with respect to the cylindrical member 10. At this time, the split groove 36 is separated from the position facing the notch 13, and the pin 4 is held in the pin insertion hole 30. When removing the pin 4, the bar member 11 is turned 90 degrees in the opposite direction to return to the state shown in FIG. Then, the pin 4 is removed from the retaining mechanism 40 by passing through the split groove 36 and the notch 13.

Each of the above embodiments is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the gist of the present invention. It is. For example, a predetermined company name or a logo may be put on a portion of the bar member 11 facing the outside of the knob portion 34, or a diamond 52 may be placed on the same portion of the knob portion 34 of the bar member 51 as shown in FIG. You may make it fit and fix. In this case, it is preferable to provide a relief hole 53 so that the tip of the diamond 52 does not abut.

The material of the rod member 11 may be stainless steel, phosphor bronze steel, nickel silver, or brass. The heat treatment temperature is about 450 ° C for stainless steel, about 350 ° C for phosphor bronze and nickel and about 300 ° C for brass, respectively. ) Is compared with beryllium copper as follows. That is, assuming that the elastic effect of beryllium copper is 10, stainless steel is 8, phosphor bronze steel is 6, nickel silver is 5, and brass is 3. On the other hand, if the formability of brass is 10, then beryllium is Copper is 8, stainless steel is 3, phosphor bronze is 8, and nickel silver is 6. From such a point, the bar member 11 is most preferably beryllium copper. In addition, although stainless steel is extremely difficult to cut, it is possible to form the shape of the rod member 11 by pressing. Also, in the jewelry field, it is preferable to avoid stainless steel and nickel silver because of the strong demand for nickel-free, but it is a matter of course that such materials may be used if necessary.

As described above, various materials can be considered as the material of the rod member 11. In addition, since the brazing temperature varies depending on the operator and the rod member 11 has a temperature of 300 to 500 ° C., the above-mentioned various materials are listed as examples of the material having the heat treatment effect in this range. Any material other than the above may be used as long as the material has a heat treatment effect in the range of -500 ° C.

Further, as shown in FIG. 17, a medal-like object engraved with “K18” on the knob 34 may be fixed with an adhesive or the like. It is desirable that the rod member 11 be heat-treated alone. In this manner, the rod member 11 in the brazed retaining mechanism can be replaced according to the decorative purpose. At the time of replacement, a load of 5 kg or more is applied for pulling out, and a force of 4 kg or more is required for reassembly. Therefore, it is preferable to use a dedicated jig.
