The lower case 2 is composed of a lower frame 4 and a lower medal 5, and the upper case 3 is composed of an upper frame 6 and an upper medal 7. The lower frame 4 is made of a relatively strong metal such as brass, and is formed into a ring shape, and an arc-shaped mounting piece 8 is integrally provided on the inner lower edge, leaving only a part. Screw insertion holes 9 are formed at these locations. The lower medal 5 is made of a precious metal such as 18K, has an upwardly projecting edge 10 formed on its outer periphery, is recessed downward on the inside, has decorations such as engravings on its outer surface, and has a screw insertion hole on the outer periphery of the recess. A blind screw hole 11 is formed corresponding to the hole 9 (see FIG. 4).

This lower medal 5 is fitted into the lower frame 4, and the screw 12 is screwed into the blind screw hole 11 from the screw insertion hole 9, and the lower medal 5 is removably fixed to the lower frame 4, thereby forming the lower case 2. ing. Like the lower frame 4, the upper frame 6 is made of a relatively strong metal such as brass, and is formed into a disc shape, with a protruding edge 13 formed on the outer periphery and a shallowly recessed inner side upward. Screw insertion holes 14 are formed at multiple locations on the outer periphery of the entry portion. The upper medal 7 is made of a precious metal such as 18K, and has a protrusion 15 formed on its outer periphery, the inside of which is recessed upward, the outer surface is decorated with engravings, etc., and the outer periphery of the recess corresponds to the screw insertion hole 14. A blind screw hole 16 is formed (see FIG. 5).

This upper medal 7 is fitted into the upper frame 6, and the screw 17 is screwed into the blind screw hole 16 from the screw insertion hole 14.
An upper medal 7 is removably fixed to the upper frame 6, and an upper case 3 is configured. These lower case 2 and upper case 3 are connected by a hinge mechanism 18 so that they can be opened and closed.

That is, as is clear from FIG. 1, FIG. 3, and FIG. It is inserted into the notch 20 formed. A cutout 21 having an arc-shaped cross section is formed at the upper part of the outer longitudinal direction of the protrusion 19, and a lower outer end surface 22 of this cutout 21 is formed.
is inclined so as to gradually protrude outward as it reaches the lower edge side, and is set at 60 degrees with respect to the horizontal plane in the illustrated example. An inclined surface 23 that coincides with this inclined outer end surface 22 is also formed on the outside of the notch 20 of the lower medal 5. A cylindrical body 24 is fixed to both sides of the notch 21 between the opposing walls of the notch 20 of the lower medal 5 by means such as brazing.

On the other hand, a protrusion 25 that matches the protrusion 19 is integrally provided on the outside of the upper frame 6, and the protrusion 25 is inserted into a notch 26 formed in the outer circumference of the upper medal 7. A notch 27 having an arcuate cross section is formed at the lower part of the outer longitudinal direction of the protrusion 25, and the upper outer end surface 28 of this notch 27 is inclined so as to gradually protrude outward as it reaches the upper edge side, and in the illustrated example, is inclined with respect to the horizontal plane. It is set at a 60 degree angle. An inclined surface 29 coinciding with this inclined outer end surface 28 is also formed on the outside of the notch 26 of the upper medal 7. A cylindrical body 30 is fixed to the center of the notch 27 between the opposing walls of the notch 26 of the upper medal 7 by means such as brazing.

The cylindrical body 30 of the upper frame 6 is inserted between the cylindrical bodies 24 of the lower frame 4 so that their axes coincide with each other. A pin 31 is inserted between the opposing walls of the notch 26 .

Therefore, a portion of both end surfaces of the cylinder body 24 and the pin 31, in the illustrated example, a portion within a range of 240 degrees inward from the axis is held between the opposing walls of the notches 20 and 26 and prevented from coming out, and the upper case 3 is pin 3 for lower case 2
It can be opened and closed around 1. Since the slope angles of the slopes 23 and 29 are set at 60 degrees with respect to the horizontal plane, the upper case 3 can be opened at an angle of 120 degrees with respect to the lower case 2.

As is clear from FIGS. 1 and 4, a notch 32 is formed in the lower frame 4 of the lower case 2 in the circumferential direction, leaving the upper surface on the inner side opposite to the hinge mechanism 18, and continuing from one side of the notch 32. Notch 33 that opens in the axial direction
is formed. Notch 33 within notch 32
A screw hole 34 is formed in the diametrical direction on the opposite side, and a hole 35 is formed in the diametrical direction at the notch 33. A locking leaf spring 36 is housed in the notches 32 and 33, and the base of the locking leaf spring 36 is fixed to the screw hole 34 by a screw 37. A locking portion 38 formed at the top of the tip of the locking leaf spring 36 projects upward from the notch 33, and this locking portion 38 locks into a locking portion 39 formed by a notch inside the upper frame 6. and upper frame 6 and upper medal 7
An upper case 3 made up of the above is held in a closed state with respect to a lower case 2 made up of the lower frame 4 and the lower medal 5. A hole 40 corresponding to the hole 35 of the lower frame 4 and having a slightly smaller diameter than the hole 35 is formed inside the outer peripheral part of the lower medal 5, and a hole 41 larger than the hole 40 is formed in communication with the outside of this hole 40. ing. There is an operation button 4 in the hole 40.
2 is inserted into the hole 35 of the lower frame 4, and the head 44 of the operation button 42 is inserted into the hole 41. A cylindrical body 45 is attached to the inwardly protruding portion of the shaft portion 43.
is fitted, and the cylindrical body 4 is fitted to the inwardly protruding end of the shaft portion 43.
A groove 46 is formed on the front side of 5, and this groove 46
An E-ring 47 is engaged with the E-ring 47, and the cylindrical body 45 is prevented from coming off. The operation button 42 can be slid slightly in the diametrical direction, is urged outward by the locking plate spring 36, and the cylindrical body 45 engages with the inner surface of the lower medal 5 to prevent it from coming off.

Therefore, press the operation button 42 and release the locking leaf spring 36.
The locking portion 38 is curved inward against its elasticity.
can be released from the locking portion 39 of the upper frame 6.

In particular, as is clear from FIGS. 1 and 5, the watch body 48 is stored in the lower case 2 and the upper case 3, that is, the empty space of the watch case 1, with the watch face facing upward. Lower frame 4 of case 2
The upper case 3 is connected by a hinge mechanism 49 such that it can be raised and lowered in a direction perpendicular to the opening and closing direction of the upper case 3.

That is, a notch 50 is formed on the upper side of the lower frame 4,
A hole 51 is formed in both walls of the notch 50 at the center of the notch 50 in the lower frame 4, and the notch 50 is formed in this hole 51.
A pin 52 passing through is press-fitted and fixed.

At the top of this pin 52 is a body 53 of the watch body 48.
The arc-shaped engagement groove 5 inside the engagement portion 54 protrudes from the
5 is engaged, the base of the engagement plate spring 56 is fixed to the barrel 53 by a screw 57, and an arc-shaped engagement part 58 formed at the tip of the engagement plate spring 56 is engaged with the lower side of the pin 52. Due to the elasticity of this engagement plate spring 56, this engagement plate spring 56 and the engagement portion 5
4 firmly grips the pin 52.

Therefore, as shown in FIGS. 6 and 7, the watch main body 48 can be rotated about the pin 52, and can be held at any angle by the frictional resistance caused by the elasticity of the engagement plate spring 56.

This watch body 48 has the upper surface of the body 53 lower than the medal 5.
Rotation is restricted by engaging with the inner edge of the projecting edge 10, and in the illustrated example, this angle is set to approximately 100 degrees. The reuse 60 of the watch body 48 is arranged on the opposite side of the hinge mechanism 49,
Claws 61 for separating the watch body 48 from the lower frame 4 are integrally protruded from the body 53 on both sides of the watch 60.

On the other hand, a claw 61 can be inserted into the lower frame 4,
An arcuate notch 62 having a diameter larger than the outer shape of the claw 61 is formed. This notch 62 is formed so that its diameter gradually decreases from the upper end to the lower end, and a notch 63 for allowing the reuse 60 to escape is formed at the lower center of this notch 62.

Therefore, by inserting the reuse 60 into the notch 63 and the claw 61 into the notch 62, the lower half of the watch body 48 can be stored in the lower case 2.

Further, the upper surface of the claw 61 is arranged so as to be close to the upper frame 6 when the upper case 3 is closed, so as to prevent the watch body 48 from moving within the watch case 1 when the watch is carried. A hanging ring 64 is integrally provided on the outside of the lower medallion 5 on the opposite side of the hinge mechanism 18 to connect one end of a chain or the like.

The pocket watch of the present invention has the operation button 4 as described above.
2, the locking part 38 of the locking leaf spring 36 is released from the locking part 39 of the upper frame 6, and the upper frame 6 and the upper medal 7 are opened by the hinge mechanism 18, thereby locking the clock in the watch body 48. By exposing the screen, you can learn the time, etc.

Also, hang the claw 61 with your fingertip etc.
By rotating and raising the clock using the hinge mechanism 49, it is possible to not only enhance the display effect as a product but also use it as a table clock. If the watch body 48 is held by frictional resistance due to the elasticity of the leaf spring 56,
can be raised steplessly to any angle.

Furthermore, if the watch body 48 is battery-powered, the watch body 48 can be removed from the lower frame 4 by removing the screws 57 and the engagement plate springs 56 while the watch body 48 is in the upright position. Replacement work can be done easily.

On the contrary, the watch body 48 is rotated by the hinge mechanism 49, and then the upper frame 6 and the upper medal 7 are rotated.
By closing with the hinge mechanism 18, the watch body 48 can be stored.

[Effect of idea]

As is clear from the above explanation, according to the present invention, the lower case and the upper case that constitute the watch case have a lower medal and an upper medal attached to the lower frame and the upper frame, respectively.
The lower frame and the upper frame are connected so that they can be opened and closed, and the lower frame and the watch body are also connected so that they can rotate, and the lower frame and the upper frame are removably locked using a locking leaf spring. , the highly decorative upper and lower medals do not have direct rotating parts, locking parts, etc.
Wear and damage to the upper medal and lower medal can be prevented.

In addition, since the lower medal and upper medal are removably attached to the lower frame and upper frame, they can be repolished as necessary.

Furthermore, since the lower medal and the upper medal are reinforced by the lower frame and the upper frame, it is possible to form them thinly, reduce weight, and reduce costs. Furthermore, since the clock body is rotatably connected to the lower frame so that the clock face can rise and fall steplessly at any angle, it not only improves the display effect as a product, but also allows it to be used as a table clock. There are also advantages such as being able to
