Description

The present invention relates to an accessory such as a wrist watch.

The wristwatch has a band connected to the wristwatch body. The wristwatch is attached to the wrist by winding the band around the wrist. Here, the wristwatch body and the band are connected by a spring rod. The spring rod is formed into a rod shape as a whole, and is configured to expand and contract in the axial direction which is the length direction. Specifically, a pin member having a pin formed at its tip is arranged at each end of the spring rod, and each pin member is axially outwardly moved by a coil spring arranged between the two pin members. It is in a pressed state. The pin member and the coil spring are housed in a cylindrical case. Then, by contracting the coil spring, the pin member can be moved toward the central portion side in the axial direction, and the length is shortened.

On the other hand, the case of the wristwatch body is formed with a lug protruding outward. Two lugs form a pair of band attachments, and a wristwatch has two pairs of band attachments. Holes into which the pins of the pin members of the spring rods are inserted are formed in the surfaces of the two paired lugs facing each other. Then, the pins of the spring rods, which are passed through in the width direction of the band, are inserted into the holes of the corresponding lugs in the end portions (end pieces) provided at the respective ends of the band, so that the band and the wristwatch The main body is connected.

The band can be removed from the wristwatch body by pulling out the pin from the fitting hole by contracting the coil spring of the spring rod from the state where the band and the wristwatch body are connected. Here, the pin member is formed with a hook portion which serves as a clue for contracting the coil spring, but is very small because it is a portion for hooking a thin tool or the like. Therefore, if the coil spring is contracted with a tool and one of the pins is removed from the fitting hole and the tool accidentally comes off (separates) from the hooked part, the elastic force of the contracted coil spring will be lost. When the pin pops back to its original state due to the action of the pin, and the relative movement of the pin with respect to the case stops, the kinetic energy of the pin induces the movement of the entire spring rod, and the spring rod jumps out vigorously from the end part. Can happen.

Therefore, there is one in which a hooking portion is provided so as to protrude from the outer peripheral surface of a cylindrical case and an operating portion that can be operated with a finger is provided. Further, the end portion of the band is formed with a guide notch for exposing the operation portion arranged in the insertion hole and permitting movement of the operation portion corresponding to the movable range of the operation portion. ..

Here, in order to maintain the coil spring in a contracted state, the end portion has a notch extending in the axial direction through which the operating portion passes in response to the expansion and contraction of the coil spring, and the axial movement of the operating portion. It is proposed to form a notch that is restricted in the circumferential direction and is branched (for example, see Patent Document 1).

Japanese Utility Model Publication No. 57-052817

However, it is difficult to actually manufacture the notch having the complicated shape formed in the end portion of the band described in Patent Document 1. It should be noted that this problem does not occur only in a wristwatch in which a band and a wristwatch main body are connected by a spring rod, and also in an accessory such as an accessory in which a band and a band connected body to which this band is connected are connected by a spring rod. The same happens.

The present invention has been made in view of such circumstances, and it is possible to prevent or suppress the spring bar from popping out without forming a complicated notch at the end of the band through which the spring bar is passed. The object is to provide jewelry such as a wristwatch that can be used.

According to the present invention, a tubular case, pin members arranged inside the case at both ends in the axial direction of the case, and arranged inside the case to press the pin member outward in the axial direction. An elastic member, and an operation portion that protrudes to the outside of the outer peripheral surface of the case and that can perform a moving operation to displace the pin member inward in the axial direction against the pressing of the elastic member. The spring rod, an insertion hole extending in the width direction in which the spring rod is arranged, and the operation portion of the spring rod arranged in the insertion hole, and one end of the insertion hole is opened. As a band in which a guide notch is formed to project so as to allow the operation portion to move within a movable range, and the pin member of the spring rod arranged in the insertion hole are fitted to each other. And a banded body having a fitting hole, wherein the operation portion in a state in which the pin member is displaced inward in the axial direction is opened after the pin member is not displaced. The cutout is arranged in the axial direction of the spring rod arranged in the insertion hole so that the operating portion contacts at least a part of the wall surface formed by the cutout within a range of moving to the end. It is an accessory that extends in an inclined direction.

According to the accessory according to the present invention, it is possible to prevent or suppress the spring bar from jumping out without forming a complicated notch in the end of the band through which the spring bar is passed.

Hereinafter, an embodiment of an accessory according to the present invention will be described with reference to the drawings.
<Overall structure of watch>
FIG. 1 is a plan view showing a back surface side (a back cover side opposite to a dial) of a wrist watch 1 which is an embodiment of an accessory according to the present invention. The wristwatch 1 shown is a wristwatch mainly for women. The wristwatch 1 includes a wristwatch body 10 (an example of a banded body), a metal bracelet 20 (an example of a band), and a spring rod 30, and the wristwatch body 10 and the bracelet 20 are connected by the spring rod 30. Has been done.

(Spring rod)
FIG. 2 is a perspective view showing the spring rod 30, and FIG. 3 is a sectional view showing a cross section of the spring rod 30 shown in FIG. The illustrated spring rod 30 includes a case 31, pin members 32 and 33, a coil spring 35 (an example of an elastic member), and an operation unit 34. As shown in FIG. 2, the case 31 has a cylindrical shape, and both ends thereof are narrowed. Therefore, the diameter of the openings at both ends is smaller than the inner diameters other than at both ends. Further, on a part of the peripheral wall of the case 31, an operation portion 34, which will be described later, is projected to the outside of the case 31 and slides as an opening that allows the operation portion 34 to move along the cylindrical axial direction L1 of the case 31. The window 31a is formed.

The two pin members 32 and 33 are arranged inside the case 31 at both ends of the case 31 in the axial direction L1. As shown in FIG. 3, one pin member 32 is formed with a flange portion 32b having a diameter larger than that of the narrowed end portion of the case 31, and is formed inside the case 31 along the axial direction L1. Although it is movable, the collar portion 32b is held by the case 31 by being hooked on the end portion of the case 31. A coil spring 35 is in contact with the flange portion 32b from the central portion side in the axial direction L1 of the case 31, and is pressed outward from the coil spring 35 in the axial direction L1. The pin member 32 is formed in a cylindrical shape with a diameter smaller than that of the opening, and has a pin 32a formed outside the flange portion 32b in the axial direction L1 and protruding from the case 31.

The other pin member 33 is formed with a cylindrical portion 33b having a diameter larger than that of the narrowed end portion of the case 31, and is movable inside the case 31 along the axial direction L1. The part 33b is hooked on the end of the case 31. A coil spring 35 is in contact with the columnar portion 33b from the center side in the axial direction L1 of the case 31, and is pressed outward from the coil spring 35 in the axial direction L1. The pin member 33 is formed in a cylindrical shape having a diameter smaller than that of the opening, and has a pin 33a formed outside the cylindrical portion 33b in the axial direction L1 and protruding from the case 31.

Like the pin members 32 and 33, the coil spring 35 is arranged inside the case 31 and between the pin members 32 and 33. The natural length of the coil spring 35 is longer than the length when it is arranged between the pin members 32 and 33 inside the case 31. Therefore, the coil spring 35 presses the pin members 32 and 33 to the outer side (the end side) in the axial direction L1 by the elastic force.

The operation portion 34 is formed integrally with the one pin member 33. Specifically, as shown in FIG. 3, the pin member 33 is formed so as to project from the cylindrical portion 33b to the outer side in the radial direction of the cylindrical portion 33b. The operation portion 34 is configured by a head portion 34a on the tip side and a neck portion 34b that is joined to the column portion 33b inside the head portion 34a. The head portion 34a is formed to be larger than the neck portion 34b, and has a size such that a finger can be hung on the hand and a load can be applied along the axial direction L1.

Further, the neck portion 34b of the operation portion 34 penetrates the sliding window 31a of the case 31 to expose the head portion 34a to the outside of the outer peripheral surface of the case 31. The operation unit 34 is movable along the axial direction L1 within the range of the sliding window 31a, and a finger or the like is hung on the head 34a of the operation unit 34 to move toward the center side in the axial direction L1 within the range of the sliding window 31a. By applying the directed load, the pin member 33 to which the operation portion 34 is joined can be displaced inward (in the central portion side) in the axial direction L1 against the elastic force of the coil spring 35.

(Watch body)
4 is a longitudinal sectional view along the axial direction L1 showing the relationship between the lug 12 formed on the wristwatch body 10, the end piece 21 of the bracelet 20 and the spring rod 30, and FIG. 5 is formed on the end piece 21. FIG. 6 is a plan view showing the relationship between the notch 21c and the operating portion 34, and FIG. 6 is an enlarged cross-sectional view taken along the line I-I in FIG.

The wristwatch body 10 accommodates a movement, a dial, hands, etc. inside a case 11 and a windshield. As shown in FIG. 1, the case 11 is formed with four lugs 12 protruding outward. The two lugs 12 form a pair of band mounting portions, and the wristwatch 1 has two pairs of band mounting portions. As shown in FIG. 4, the pins 32a of the pin member 32 of the spring rod 30 and the pin 33a of the pin member 33 are fitted to the surfaces 12p and 12p of the two paired lugs 12 and 12 facing each other. Joint holes 12a, 12a are formed.

The dimension between the facing surfaces 12p, 12p is longer than the length of the case 31 of the spring rod 30, but the overall dimension of the spring rod 30 (the axis of the pin members 32, 33 in a state where no load is applied to the operating portion 34). Shorter than the dimension between the outermost surfaces along the direction L1). Therefore, when the load is not applied to the operation portion 34, the pins 32a and 33a of the spring rod 30 are inserted into the fitting holes 12a and 12a, respectively, so that the spring rod 30 becomes a pair of band attachment portions. Retained.

On the other hand, in the state in which the load toward the central portion side in the axial direction L1 is applied to the operating portion 34 in the range of the sliding window 31a and the pin member 33 is displaced to the central portion side in the axial direction L1 most, The pin 33 a of the pin member 33, which is integral with the unit 34, comes out of the fitting hole 12 a of the lug 12. Therefore, by tilting the spring rod 30 so as to retract the pin 33a from the facing surface 12p of the lug 12 in a state where the pin 33a is removed from the fitting hole 12a, the pin 32a of the other pin member 32 is also attached to the lug 12. It can be pulled out from the fitting hole 12a, and the spring rod 30 is not held by the pair of band attaching portions.

In the wristwatch 1 of the present embodiment, the two fitting holes 12a, 12a penetrate to the surface opposite to the facing surfaces 12p, 12p, but the fitting holes 12a, 12a are punched. This is for facilitating the manufacturing in the case of forming it by forming. Therefore, the fitting holes 12a, 12a do not have to penetrate to the surface opposite to the facing surfaces 12p, 12p.

(bracelet)
The bracelet 20 is made of metal and is provided with end pieces 21 at both ends of the band. As shown in FIG. 4, each end piece 21 is formed with an insertion hole 21 a that extends in the width direction of the bracelet 20 (direction orthogonal to the length direction of the bracelet 20) and in which the spring rod 30 is arranged. ing. Further, the end piece 21 is also formed with another insertion hole 21b through which a connecting rod for connecting to another piece of the bracelet 20 adjacent to the end piece 21 is inserted.

The end piece 21 is formed such that the width thereof is slightly narrower than the dimension between the facing surfaces 12p, 12p of the pair of lugs 12, 12, and the spring rod 30 is arranged in the insertion hole 21a. Only the pins 32a and 33a at both ends of the spring rod 30 arranged in the insertion hole 21a are projected outside the width of the piece 21.

Further, as shown in FIG. 5, a guide for causing the operating portion 34 of the spring rod 30 arranged in the insertion hole 21a to project into the end piece 21 so as to allow the operating portion 34 to move within a movable range. A notch 21c for forming is formed. The notch 21c reaches one side surface in the width direction of the end piece 21, and the end portion forms an open end 21h that is open to the side surface.

In addition, the notch 21c has the operation portion 34 in a state in which the pin member 33 is displaced toward the central portion side (inner side) in the axial direction L1 and is moved to the open end 21h after the pin member 33 is not displaced. The operating portion 34 is formed so as to come into contact with at least a part of the wall surface 21d formed on the end piece 21 formed by the notch 21c within the range until the movement. The notch 21c is, for example, in a range before the pin member 33 is displaced toward the central portion side along the axial direction L1 before returning to the state where the pin member 33 is not displaced. It can be formed so as to contact 21d. In this case, specifically, the notch 21c is in a direction L2 inclined by an angle θ (θ≠0) [degree] with respect to the axial direction L1 of the spring rod 30 arranged in the insertion hole 21a of the end piece 21. It can be formed to extend.

This angle θ is, for example, 2.5 [degrees], but is not limited to this angle. That is, the angle may be more than 2.5 [degrees] as long as the operation unit 34 in contact with the wall surface 21d can be moved toward the central portion side (inner side) in the axial direction L1. However, if the angle θ is excessively large, the resistance at the time of moving the operation unit 34 toward the central portion side (inner side) in the axial direction L1 becomes large and it becomes difficult to operate, or the finger from the operation unit 34 is removed. After being separated, the operating portion 34 may not return to the original position only by the elastic force of the coil spring 35. Therefore, the angle θ is preferably set in a range where such a problem does not occur, and for example, a range of 2 to 5 [degrees], more preferably a range of 2 to 3 [degrees] is suitable.

Two wall surfaces 21d and 21e facing each other formed by the notch 21c are formed in parallel with each other, and the dimension between the two wall surfaces 21d and 21e is as shown in FIG. It is set wider than the thickness of 34b and narrower than the thickness of the head 34a.

Since the wall surface 21e is inclined by the angle θ with respect to the axial direction L1, when the operating portion 34 is displaced toward the central portion side along the axial direction L1, while temporarily pressing the operating portion 34 toward the wall surface 21e side. Even if operated, the operating portion 34 contacts a part of the wall surface 21e to guide the operating portion 34 in the direction of the angle θ. As a result, when the operating portion 34 is displaced toward the central portion side in the axial direction L1, the operating portion 34 is brought closer to the wall surface 21d side with respect to the axial direction L1 and is closer to the central portion side in the axial direction L1. The operation part 34 is more reliably brought into contact with the wall surface 21d until the operation part 34 moves to the open end 21h after passing through the position before the displacement by the elastic force of the coil spring 35 after releasing the displaced operation part 34. be able to.

Further, the two wall surfaces 21d and 21e formed by the notch 21c in the wristwatch 1 of the present embodiment and facing each other are parallel, but the two wall surfaces 21d and 21e do not have to be parallel.

<Action>
FIG. 7 is a plan view corresponding to FIG. 5, showing a state in which the operating portion 34 of the spring rod 30 is moved toward the central portion along the axial direction L1 of the spring rod 30. According to the wristwatch 1 configured as described above, when the bracelet 20 is removed from the state where the end piece 21 of the bracelet 20 is connected to the lugs 12, 12 of the wristwatch body 10 by the spring rod 30 (see FIG. 5). 7, a finger is put on the operating portion 34 (particularly the head portion 34a) of the spring rod 30 to resist the elastic force of the coil spring 35, and the operating portion 34 is moved in the axial direction L1 of the spring rod 30. Move to the center side along. At this time, the pin 33a of the pin member 33 integrated with the operating portion 34 is in a state of being pulled out from the fitting hole 12a (see FIG. 4) of the lug 12 on the right side in the drawing.

In this state, by adjusting the inclination of the end piece 21 so that the pin 33a retracts from the facing surface 12p of the lug 12, one end of the end piece 21 in the width direction is provided with two lugs that are band attachment portions. Evacuate between 12 and 12. In this state, the pin 32a of the other pin member 32 is still inserted in the fitting hole 12a of the lug 12.

Here, when the finger hanging on the operating portion 34 is released from the operating portion 34, the operating portion 34 is moved along the axial direction L1 of the spring rod 30 by the elastic force of the coil spring 35 acting on the pin member 33. Within the range of the sliding window 31a, the outer side (outside of the pin member 33 side) is displaced relative to the case 31. When the neck portion 34b reaches the end of the sliding window 31a and hits the case 31, the relative movement of the operation portion 34 and the pin member 33 with respect to the case 31 is stopped, but the kinetic energy of the operation portion 34 and the pin member 33 is reduced by the spring rod 30. It acts on the whole and the spring rod 30 moves along the axial direction L1 so as to jump out from the insertion hole 21a of the end piece 21.

When the spring rod 30 pops out from the insertion hole 21a of the end piece 21, the operation portion 34 passes through the notch 21c formed in the end piece 21, but as shown in FIG. In contrast to the direction L1, the notch 21c extends along the direction L2 inclined by the angle θ with respect to the axial direction L1. Therefore, when the spring rod 30 tries to jump out from the insertion hole 21a, the lower portion of the head portion 34a of the operation portion 34 that moves along the axial direction L1 mainly contacts the wall surface 21d formed by the notch 21c. .. The frictional force generated by this contact reduces the kinetic energy of the spring rod 30, reduces the speed of the spring rod 30 protruding from the insertion hole 21a, or suppresses the spring rod 30 from protruding.

As described above, according to the wristwatch 1 of the present embodiment, the end piece 21 of the bracelet 20 through which the spring rod 30 is inserted is not formed with a notch having a complicated shape, that is, the end piece 21 is conventionally formed. With the structure in which the notch is merely changed to the direction L2 slightly inclined with respect to the axial direction L1 of the spring rod 30, the spring rod 30 can be effectively prevented or suppressed from protruding.

Further, in the wristwatch 1 of the present embodiment, since the notch 21c formed in the end piece 21 has the two wall surfaces 21d and 21e facing each other formed by the notch 21c that are parallel to each other, processing such as turning is performed. Can be easily formed by.

The notch in the present invention is not limited to one in which two wall surfaces formed by the notch and facing each other are parallel to each other. FIG. 8 is a plan view corresponding to FIG. 5 showing an example in which two wall surfaces 21d and 21e formed by the notch 21c and facing each other are not parallel to each other.

The notch 21c of the end piece 21 shown in FIG. 8 has a wall surface 21d on the side closer to the axial center of the spring rod 30 as it goes to the end (open end 21h) of the notch 21c. In the embodiment shown in FIG. 5, the wall surface 21e on the side farther from the axial center of the spring rod 30 as it goes to the end (open end 21h) of the cutout 21c is the same as the cutout 21c. In the present embodiment, the spring rod 30 extends along the direction L3 parallel to the axial direction L1 of the spring rod 30 without moving away from the axial center of the spring rod 30. Even if the notch 21c forms such wall surfaces 21d and 21e, the operation portion 34 that moves outward in the axial direction L1 can be brought into contact with the wall surface 21d, and the wristwatch 1 according to the above-described embodiment. Has the same effect as.

In the embodiment shown in FIG. 8, the gap between the dimension (width) between the wall surfaces 21d and 21e at the open end 21h of the notch 21c and the portion of the operation portion 34 sandwiched between these wall surfaces 21d and 21e is set. By narrowing it, it is possible to bring the operating portion 34 into contact with the wall surface 21d more reliably.

The notch in the present invention is not limited to one in which two wall surfaces facing each other formed by the notch are each formed of a single plane. FIG. 9 is a plan view corresponding to FIG. 5, showing an example in which two wall surfaces facing each other formed by the notch 21c are formed by two curved flat surfaces.

The notch 21c of the end piece 21 shown in FIG. 9 forms two wall surfaces 21d and 21e parallel to the direction L2 inclined with respect to the axial direction L1 of the spring rod 30 on the open end 21h side of the notch 21c. Two wall surfaces 21f and 21g extending along a direction L4 parallel to the axial direction L1 of the spring rod 30 are formed on the open end side of the notch 21c. Even if the notch 21c forms two curved flat surfaces (wall surfaces 21d, 21f and wall surfaces 21e, 21g) as two wall surfaces facing each other in this way, it faces outward in the axial direction L1. The moving operation unit 34 can be brought into contact with the wall surface 21d, and the same effect as that of the wristwatch 1 of the above-described embodiment is exhibited.

As a modified example of the example shown in FIG. 9, the wall surface formed by the notch 21c may be formed by a curved surface instead of two flat surfaces. For example, the wall surfaces 21f and 21g may be formed as curved surfaces that bend with a small curvature from the central portion side along the axial direction L1 toward the open end 21h.

Further, in the wristwatch 1 of the present embodiment, the notch 21c formed in the end piece 21 is inclined in a direction L2 that is closer to the wristwatch body 10 as it approaches the end of the insertion hole 21a than in the axial direction L1. There is. Since the notch 21c is formed on the surface facing inward when the wristwatch 1 is worn on the wrist, the notch 21c is hidden by the lug 12 at the same time as being placed on the back side when the wristwatch 1 is worn on the arm. Therefore, it is hard to be noticed. However, even if the arrangement is on the back side, the end of the cutout 21c is open, and therefore, when the end of the end piece 21 is rotated, the open end 21h of the cutout 21c may be closed when the end of the cutout 21c approaches the tip of the lug 12. To the side opposite to the wristwatch body 10 side, and it becomes easy to see from the outside.

Since the notch 21c in the wristwatch 1 of the present embodiment has the inclination as described above, the open end 21h at the end of the notch 21c approaches the root of the lug 12, so that the open end 21h of the notch 21c becomes the lug 12. The open end 21h is less visible from the outside than the one approaching the tip of the. Therefore, the wristwatch 1 of the present embodiment can reduce the influence of the cutout 21c on the appearance quality.

FIG. 10 corresponds to FIG. 5 showing an example of the end piece 21 in which the notch 21c is tilted in the direction L5 in the direction away from the wristwatch body 10 as it approaches the end of the insertion hole 21a rather than in the axial direction L1. FIG. As described above, the wristwatch 1 of the embodiment having the end piece 21 having the notch 21c shown in FIG. 10 has a notch as compared with the wristwatch 1 of the embodiment having the end piece 21 shown in FIG. The open end 21h of the end of 21c may be easily visible from the outside, but the operating portion 34 comes into contact with the wall surface 21e formed by the cutout 21c, effectively preventing the spring rod 30 from popping out. Alternatively, it can be suppressed, and can be an example of the accessory according to the present invention.

In the wristwatch 1 of the present embodiment, as shown in FIG. 1, with the wristwatch 1 on the back side and the end piece 21 arranged on the upper side with respect to the wristwatch body 10, the notch 21c has an end portion as shown in FIG. Although the open end 21h is formed on the right side in the width direction of the piece 21, the present invention is not limited to this form and is symmetrical with the end piece 21 of FIG. It may be a notch having an open end 21h formed on the left side of.

As shown in FIG. 1, the wristwatch 1 of this embodiment has a charm (small accessory) 19 added to a lug 12. The charm 19 includes an ornament 19a and a ring 19b added to the ornament 19a. The charm 19 is attached to the wristwatch 1 in a state where the lug 12 is passed through the ring 19b and the end piece 21 of the bracelet 20 is connected to the lug 12. Retained. Then, when replacing the charm 19 held in this way with another type of charm, it is necessary to remove the end piece 21 from the lug 12 in the manner described above. Therefore, in the wristwatch 1 in which the replaceable charm 19 is held on the lug 12 in this manner, the chances of attaching and detaching the end piece 21 increase, and the above-mentioned effects increase, which is more effective. ..

As shown in FIG. 1, slopes 12q and 12q that are inclined with respect to the facing surfaces 12p and 12p are formed on the rear surface (the surface corresponding to the back side of the wristwatch 1) near the facing surfaces 12p and 12p of the lug 12. However, in FIG. 5, the inclined portions 12q and 12q are omitted. The inclined portions 12q and 12q are located between the lugs 12 and 12 from the back side of the wristwatch 1 in a state where the spring rod 30 is inserted into the insertion hole 21a of the end piece 21 and the pins 32a and 33a project from the insertion hole 21a. When inserting the end piece 21 into the, the pins 32a and 33a are formed so as to be guided into the insertion holes 21a and 21a of the lug 21 while the spring rod 30 is contracted.

Note that the lug 12 has a shape in which the root side is narrower than the tip end portion and is constricted, so that the lug 12 and the main body portion of the case 11 (a tubular portion accommodating a movement or the like), and the end piece 21. Of the space surrounded by, the space in which the ring 19b of the charm 19 moves can be widened. Thereby, the ring 19b can be easily moved, and the charm 19 can be easily moved.

In the wristwatch 1 of the above-described embodiment, the operation portion 34 is brought into contact with the wall surface 21d formed by the notch 21c of the end piece 21, but the operation portion 34 actually comes into contact with the entire surface of the wall surface 21d. Since the contact is not a contact (a surface contact) but a linear contact (a line contact), the wall surface formed by the cutout 21c may have a linear portion at a portion contacting the operation portion 34.

In the spring rod 30 in the present embodiment, the pin member 32 on the side to which the operation portion 34 is not joined is configured separately from the case 31, but the pin member 32 moves relative to the case 31.
