Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of compounding a portable watch mainly for combining it with another article. More specifically, the present invention relates to a multifunctional portable watch in which lenses, ornaments, and the like are integrated with a portable watch to enhance practical convenience and commercial value.

[0002]

2. Description of the Related Art As a composite product in which a portable watch, which is a necessity of life, and reading glasses, which are a necessity of a presbyopia,
Cellular watches with loupe are already available. Incidentally, these technologies are described in No. 3030481 and No. 3
015254/3015254/303355
No. 5, etc., are disclosed in each registered utility model gazette.

The practical convenience emphasized in these known examples of portable watches with a loupe is as follows. A small object can be magnified through a loupe combined with a timepiece. In the case where the clock function and the magnifying glass function are provided as a single component, the loupe is used as a substitute for the reading glasses, so that the convenience is improved. The front side of the watch is covered with a loupe. That is, since the front side of the timepiece is double-covered by the surface protection plate and the loupe, the mechanical characteristics of this portion are enhanced, and the pivotal mechanism of the timepiece can be sufficiently protected from external impact. Since the loupe is placed on the front side of the watch, the original use of the watch is not hindered by the loupe. Since the frame is attached around the loupe, the loupe can be easily assembled to a predetermined portion of the timepiece using this. When the frame has a fulcrum projection on one side thereof, the fulcrum projection can be easily pinned to the pair of support pieces (a part of the watch case) via the connecting pin. When the frame has a projecting piece on the other side thereof, the projecting side of the frame is brought into strong contact with a part of the watch case to hold the loupe on the transparent protective plate in a closed state or use the projecting piece. And raise the loupe to a usable state. Therefore, it is easy to handle when using and storing the loupe. When the loupe frame also functions as a watch stand in a pocket watch, such a watch can be used as a table clock or an alarm clock.

[0004]

The above-mentioned known portable timepiece with a loupe is obtained by integrating a loupe on the surface of a portable timepiece and integrating them. In these cases, the watch
The appearance of the watch case is impaired because the front side of the watch case swells abnormally. Less preferable is that the refraction of the loupe and the refraction of the surface protection plate overlap when the watch surface is viewed from an oblique direction. This makes it difficult to read the time from a specific direction. As a countermeasure,
It is conceivable to prevent the hour hand, minute hand, second hand, and the like from rising greatly from the dial, or to make the surface protection plate and the loupe with little swelling. But to achieve this, the design of the watch and other things must be significantly modified. In other words, this means that a loupe, which is essentially useless for a timepiece, imposes a design and specification sacrifice. In addition, a flat surface protection plate is inferior in strength to a bulging surface protection plate. Therefore, as in the case where the loupe is opened, the protection function when the timepiece surface is protected only by the surface protection plate is reduced.

As is apparent from the above description, it is desirable that the main part of the timepiece is not significantly modified when the portable timepiece is combined with other articles. Therefore, if this kind of combination is to be achieved without significant modification, it is possible to satisfy the ease of production, appearance, low cost, etc. of the multifunctional portable watch. In addition, if the number of composite objects is increased as much as possible, a composite product having more functions can be obtained.

[Object of the Invention] The present invention has been made to solve such technical problems. Therefore, an object of the present invention is to provide a multi-function portable watch that satisfies suppression of drastic alteration of the watch portion, ease of production, appearance in appearance, low cost, and the like, and has more functions. Is to provide.

[0007]

The multifunction portable timepiece described in claim 1 of the present invention is characterized by the following means for achieving the intended purpose. That is, claim 1
The multi-function portable timepiece described has a built-in timepiece driving mechanism in the timepiece case, a time indicating mechanism assembled to the timepiece case facing the front side of the timepiece case, and a cover for covering the surface of the time indicating mechanism. In a mobile watch where a transparent surface protection plate is assembled on the front side of the watch case,
A back plate for covering the back surface of the watch case by covering the back cover side of the watch case, and a hinge for attaching the back plate to the back surface of the watch case so that the back plate can be freely opened and closed are provided. The back plate is connected to the watch case via a hinge provided between the watch case and the outer periphery of the watch case.

[0008] A multifunction portable timepiece according to a second aspect of the present invention is characterized by the following means for solving the problem in order to achieve the intended purpose. That is, in the multi-function portable timepiece according to the second aspect, the timepiece driving mechanism is built in the timepiece case, the time indicating mechanism is assembled to the timepiece case facing the front side of the timepiece case, or the surface of the time indicating mechanism is provided. In a portable watch in which a transparent surface protection plate for covering the watch case is assembled on the front side of the watch case, the cover is provided on the back cover side of the watch case to cover the back surface of the watch case, and has a frame around it. A back plate, and a hinge for attaching the back plate with the frame to the back surface of the watch case so as to be openable and closable, are provided via a hinge provided over the outer periphery of the frame of the back plate and the outer periphery of the watch case. The back plate is connected to the watch case.

A multifunction portable timepiece according to a third aspect of the present invention is the multifunction portable timepiece according to the first or second aspect, wherein the back plate is made of one of a transparent body and an opaque body.

[0010] A multifunctional portable timepiece according to a fourth aspect of the present invention is the multifunction portable timepiece according to the first or second aspect, wherein the back plate comprises a loupe lens.

[Operation] In the multifunctional portable timepiece according to the present invention, a back plate or a back plate with a frame is provided on the back surface of the watch case. Such a timepiece is a rocket because it can hold a photograph or the like between the back of the watch case and the back plate. When the back plate is made of a transparent material (transparent material), the rocket is of a type that allows the contents to be seen through, and when the back plate is made of an opaque material (opaque material), the rocket is of a type that hides the contents. If the back plate is decorated in such a timepiece, it becomes a pendant or brooch. When a decorative pattern is applied to the back of the watch case and the back plate is made of a transparent material, it becomes a pendant or brooch. When the back plate is made of a loupe lens, by opening it from the back of the watch case, small letters and pictures can be read in an enlarged manner.
Of course, if the back plate is made of a loupe lens, it will be a rocket, pendant, brooch, etc. In addition, since the back plate or the frame of the back plate doubles as a watch stand, the portable watch can be set up on a desk or a bedside using this. Therefore, the portable clock also becomes a table clock or an alarm clock.

The multi-function portable timepiece according to the present invention is of a reversible type in which functions of various articles such as a rocket, a pendant, a broach, and a loupe are provided on the front and back surfaces of a watch case. When used as a table clock or an alarm clock, the back plate or the frame of the back plate serves as a clock stand. Such a combination (multifunctionalization) depends on a back plate or a back plate with a frame attached to the back surface of the watch case via a hinge, and thus does not affect the surface of the watch case at all. Therefore, the appearance of the watch case bulges abnormally, the appearance of the watch case becomes unusual, the time reading from the oblique direction becomes difficult, and the design of the watch surface design is largely changed to solve these problems. It is possible to avoid a decrease in the strength of the surface protection plate due to flattening. In other words, this means that the characteristics of a normal timepiece can be left as they are. In addition, since the back of the watch case has a simple surface with no special accessories, it is easy to cover the back plate with the frame and fix it with a hinge. This means that the difficulty in manufacturing a multifunctional portable watch by attaching a back plate with a frame to an existing watch is reduced, which also contributes to lowering the cost of the product.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A multifunctional portable timepiece according to the present invention will be described first with reference to the embodiments illustrated in FIGS.

In the multifunctional portable timepiece illustrated in FIGS. 1 to 6, the watch portion (pocket watch) includes a watch case 11 ·
It has a drive mechanism 21, a time indicating mechanism 31, an alarm mechanism (not shown), a transparent protection plate 41, and the like. All of these timepiece components are known or known.

As the drive mechanism 21, in addition to the use of mechanical force (for example, use of a mainspring) described below, an electric drive (known or well-known) using a battery may be employed.

Referring to FIGS. 1 to 6, a watch case 11 includes a watch side 13 having a back cover 12. A raised portion 14 is integrally formed on the upper outer peripheral surface of the clock side 13. Therefore, as clearly shown in FIG. 3, the raised portion 14 has a pin shaft 2 with a crown 22 from the outside to the inside of the watch case 11.
3 is provided with an insertion hole 15 for insertion. FIG.
As is clear from FIGS. 3 and 4, a mounting portion having a pair of support pieces 16 and 17 and a vertical hole 18 having an open front end surface (lower end surface) is provided on the lower outer peripheral surface of the watch side 13. 19 are integrally formed. The connecting ring 20 having an inverted U-shape has both lower ends bent inward like hooks, and the lower ends of the connecting ring 20 are provided on both side surfaces of the raised portion 14 for holding the same. There is a dent to accept. Therefore, in the case of the connecting ring 20, both lower ends thereof are fitted into the recesses on both side surfaces of the protruding portion and are pinned to be attached to the protruding portion 14. The back cover 12 is the watch case 1
1 is held on the back side. Such a back cover 12
This can be removed from the back of the watch case 11 if necessary. The surface of the back cover 12 may be provided with one or more of a picture, a photograph, a figure, a pattern, a character, a symbol, and the like. The members constituting the watch case 11 are made of metal, clastic,
Consists of ceramics, cermets and others. As will be apparent from the following description, the mounting portion 19 is provided with a hinge H.
Which constitute a part of.

The drive mechanism 21 shown schematically in FIGS.
Is composed of a pin shaft 23 provided with a crown 22, a mainspring (not shown), and other members (known members). As is clear from FIGS. 1, 3, and 4, the driving mechanism 21
Above the dial 32, hour hand 33, minute hand 34, second hand 3
5, a time instruction mechanism 31 mainly composed of a time indicator mechanism 31 is assembled. The drive mechanism 21 and the time indicating mechanism 31 are built in the watch case 11. As a result, the crown 22 of the drive mechanism 21 projects outside the watch case 11, or the dial 32, the hour hand 33, the minute hand 34, and the second hand 45 of the time indicating mechanism 31 face the front side of the watch case 11.

1 to 6, a transparent protective plate 41 made of transparent glass or transparent plastic is for covering the surface of the time indicating mechanism 31. This is also watch 1
3 to form the surface of the watch case 11.

The back plate 51 illustrated in FIGS. 1 to 6 is provided with a frame 52 around its periphery and integrated therewith. The back plate 51 is made of, for example, a transparent body (transparent material), and is made of an opaque body (opaque material) as another example. As a transparent body for the back plate 51, a lens for a loupe (uncolored), a colored lens for a loupe, transparent glass (uncolored)
-Colored transparent glass, transparent plastic (uncolored), colored transparent plastic, etc. can be mentioned. Among these, in the case of a transparent body excluding a lens, a planar pattern or an uneven pattern for decoration may be formed, or a three-dimensional pattern such as cut glass may be provided. Of course, other decorative shapes and / or decorative patterns may be applied to the transparent body. As an opaque body for the back plate 51, glass, plastic, metal, ceramics, stone,
Trees and their composites can be mentioned. Such an opaque body may have a decorative shape and / or a decorative pattern as in the case of the transparent body.
In the illustrated example, a loupe lens (uncolored) is employed as a typical example of the back plate 51.

The frame 52 shown in FIGS. 1 to 6 is also made of metal, crust, ceramic, cermet, or the like. The material of the frame 52 often matches that of the watch case 11. In the outer peripheral portion of the frame 52, the projecting piece 53 is located at a position corresponding to the position of "1 o'clock", or the fulcrum projection 54 bent at an angle of about 90 degrees with respect to the inner surface of the frame is at the position of "6 o'clock". Or at the corresponding site. As is apparent from FIGS. 3 and 4, particularly with reference to FIG. 4, a closed holding surface (flat surface) 55, a first dead center surface (arc surface) 56, and a narrow angle open holding are provided on the outer peripheral surface of the fulcrum projection 54. Surface (flat surface) 57 / second dead center surface (arc surface) 58
A wide-angle open holding surface (flat surface) 59 and the like are formed in series. The angle between the inner surface of the frame 52 and the closed holding surface 55 is slightly smaller than 90 degrees, and the angle between the inner surface of the frame 52 and the wide-angle open holding surface 59 is 90 degrees.
Therefore, the closed holding surface 55 and the wide-angle open holding surface 59 are in a substantially parallel relationship. The included angle between the narrow-angle open holding surface 57 and the closed holding surface 55 is an obtuse angle, and the included angle between the narrow-angle open holding surface 57 and the wide-angle open holding surface 59 is an acute angle. The first dead center surface 56 interposed between the closed holding surface 55 and the narrow-angle opening holding surface 57 is a small-width circular arc surface that continues these two surfaces, and the narrow-angle opening holding surface 57 and the wide-angle opening surface The second dead center surface 58 interposed between the holding surface 59 and the second dead center surface 58 is an arc surface having a large width and these two surfaces are connected to each other. In addition, a shaft hole 60 is provided at a shaft center portion of the fulcrum projection 54, and a fulcrum shaft 61 is inserted into the shaft hole 60. Note that the fulcrum projection 54 and the fulcrum shaft 61 in the above also constitute a part of the hinge H, as will be apparent from the following description.

In FIG. 4, the pushing member 71 is formed by integrally forming a shaft portion 72 and a plate surface portion 73 at the tip of the shaft portion. The spring 74 for the pushing member 71 is a compression coil spring. The outer diameter of the spring 74 is smaller than the inner diameter of the vertical hole 18. In the pushing member 71, the outer diameter of the shaft portion 72 is smaller than the inner diameter of the spring 74, and the outer diameter of the plate surface portion 73 is larger than the inner diameter of the vertical hole 18. The pushing member 71 is made of metal or plastic, and the spring 74 is mainly made of metal.

As can be understood from FIGS. 1 to 6, particularly FIGS. 3 and 4, the back plate 51 with the frame 52 is attached to the outer peripheral portion of the watch side 13 (watch case 11) in the following procedure. First, the spring 74 and the shaft 72 of the pushing member 71
Are fitted into the vertical holes 18 of the mounting portion 19. Next, the frame 52 is covered on the transparent protection plate 41. Here, the projecting piece 53 of the frame 52 is turned to the “1 o'clock” position,
Since the fulcrum projection 54 is turned to the position of “6 o'clock”, the fulcrum projection 54 fits between the two support pieces 16 and 17. Thereafter, the fulcrum shaft 61 is inserted from the one support piece 16 into the shaft hole 60 of the support projection 54 and the other support piece 17. Thus, when the frame 52 is attached to the watch case 11 with the fulcrum shaft 61 as a fulcrum, the frame 52 attached to the front side of the watch case 11 completes the assembly of the above-described hinge H over these. Thus, the frame 52 can be opened or closed integrally with the back plate 51. Further, the pushing member 71 receiving the force in the direction of escaping from the vertical hole 20 via the spring 74 always presses the peripheral surface of the fulcrum projection 54 by the plate surface portion 73 on the distal end side.

The timepiece portion of the multifunction portable timepiece illustrated in FIGS. 1 to 6 is composed of a pocket watch. When this is used as it is as a pocket watch, it is sufficient to follow a well-known usage. Back plate 51 with frame 52 as shown in this usage mode
When the cover covers the back surface of the watch case 11, the plate surface portion 73 of the pushing member 71 is supported by the fulcrum projection 54 as shown in FIGS.
Is pressed by the force of the spring 74. The force at this time acts in the closing direction of the back plate 51. Therefore, the closed state of the back plate 51 is maintained.

When the multifunctional portable timepiece is used as a clock or an alarm clock as shown in FIG. 5, the back plate 51 with the frame 52 may be opened from the back of the watch case 11 and placed on a desk or a bedside. The opening operation at this time is as simple as putting a fingertip on the projecting piece 54 of the frame 52 in the closed state and setting the opening angle of the frame 52 with respect to the back of the watch case to about 60 degrees. In the process in which the frame 52 changes from the closed state to the open state together with the back plate 51, the fulcrum projection 54 rotates clockwise in FIGS. That is, the fulcrum projection 5
4 changes the contact surface with the plate surface portion 73 from the closed holding surface 55 to the first dead center surface 56 → the narrow angle open holding surface 57 while the pressing member 71 is temporarily pushed into the vertical hole 18 side. While the plate portion 73 is in contact with the first dead center surface 56 from the closed holding surface 55, the spring 74 receives the resistance. When the plate surface 73 reaches the narrow-angle open holding surface 57 beyond the first dead center surface 56, the direction of the reaction force is reversed. Therefore, when the plate surface portion 73 and the narrow-angle open holding surface 57 come into surface contact with each other, the pushing member 71 holds the state of FIG. By the way, in the state of FIG. 5, when a part of the hinge H comes into contact with the horizontal plane, the watch case 11 tilts backward, so that the center of gravity becomes stable. Therefore, the multifunctional portable watch does not easily fall.

When the back plate 51 provided with the frame 52 is formed of a lens, the back plate 51 is further developed as shown in FIG. 6 to bring the lens serving as the back plate 51 closer to the target. With this configuration, the small characters and pictures displayed on the target object are enlarged by the lens, so that these displays can be easily read. The deployment operation at this time is also in accordance with the above. That is, the frame 52 is rotated clockwise in FIGS. 3 and 4, and the contact surface of the fulcrum projection 54 with the plate surface portion 73 of the pushing member 71 is changed from the closed holding surface 55 → the first dead center surface 56 → the narrow angle open holding surface 57 → Two fulcrum surfaces 58 are changed like wide-angle open holding surfaces 59. In this operation, the resistance of the spring 74 is received until the plate surface portion 73 and the wide-angle open holding surface 59 come into surface contact. However, when the two surfaces 59 and 73 come into contact with each other, the pushing member 71 The state shown in FIG. 6 is held with the help of power. Therefore, in the state of FIG.
It is unlikely that the back plate (lens) 51 with two and the watch case 11 are relatively bent at the hinge H.

When closing the back plate 51 in the open state, the back plate 51 with the frame 52 is pushed back in the counterclockwise direction in FIGS. As a result, the back plate 51 with the frame 52 falls down on the back surface side of the watch case 11 and covers it.

FIG. 7 shows a multi-function portable timepiece according to the present invention.
The embodiment illustrated in FIG.

With respect to the timepiece case 11 of the multifunctional portable timepiece illustrated in FIG. 7, the mounting portion 19 is formed on the upper outer peripheral surface of the watch side 13, and the crown 32 is formed from the outer peripheral surface of the side of the watch side 13. They are protruding. Back plate 5 for this
In one frame 52, the projecting piece 53 protrudes from the lower outer peripheral surface of the frame 52, and the fulcrum projection 54 is provided on the upper outer peripheral surface of the frame 52. Thus, the mounting portion 19 and the fulcrum projection 54 are pivotally connected via the fulcrum shaft 61 so as to be relatively bendable and extendable. At this time, the connecting ring 20
Are pivotally mounted together with these on a fulcrum shaft 61. The hinge H completed by such assembling is substantially the same as the one described above because it includes the pushing member 71 and the spring 74. In the multi-function portable timepiece of FIG. 7, the description of the omitted items is similar to or substantially the same as the contents described in FIGS.

When the multifunctional portable watch of FIG. 7 is used as a table clock or an alarm clock, as shown in the figure, the back plate 51 with the frame 52 is opened from the back of the watch case 11 and put on a desk or a bedside. I just need. The opening operation at this time is not different from that described above. So, in this case,
If the tip of 3 is straight, for example, the multi-function portable timepiece will exhibit a stable standing state. When the back plate 51 is made of a lens, that is, when it is used as a loupe, the back plate 51 with the frame 52 may be developed in the manner described with reference to FIG. Of course, also in this case, similarly to the previous example, the back plate (lens) 51 with the frame 52
It is unlikely that the watch case 11 is relatively bent at the hinge H.

There are also the following embodiments of the multifunction portable timepiece according to the present invention. One is that a back plate 51 without a frame 52 is employed. Such a frameless back plate 51 is often used when the back plate 51 is made of a material having excellent strength (eg, metal). Therefore, in the case of this example, the projecting piece 53 and the fulcrum projection 54 are provided on the outer peripheral portion of the frameless back plate 51. The other is an embodiment of the hinge H, in which the fulcrum projection 54 is provided on the outer peripheral portion of the watch side 13 (watch case 11), or the mounting portion 19 is provided on the outer peripheral portion of the back plate frame 52 or the frameless back plate 51. Or they are connected by a fulcrum shaft 61. When the drive mechanism 21 is of an electric type, the crown 22 is eliminated, but a small operation button instead of the crown 22 is used.
May protrude from the outer peripheral surface. The size of a multi-function portable watch is 5 mm in diameter mainly for pocket watches.
It is about 0 to 60 mm, but the diameter used for rockets, pendants, brooches, etc. is 2 mm.
It becomes about 0 to 50 mm. The back plate 51 and the frame 52 also have a size corresponding to this. In addition, the outer shape of the multifunctional portable watch may be elliptical or polygonal (for example, square or larger). When carrying or wearing such a multifunctional mobile watch,
Chains, necklaces, metal fasteners, hanging hardware, and the like are connected or attached to the connection ring 20.

[0030]

The multifunction portable timepiece according to the present invention has the following effects.

In addition to a timepiece, it can be used as a loupe, a rocket, a pendant, a broach, and the like, so that one article has more functions.
In addition, in the usage mode of the clock, the mobile clock, table clock,
It is easy to use because it becomes various clocks such as alarm clocks. Therefore, it becomes a multifunctional portable watch with high added value, and its convenience is also enhanced.

A back plate or a back plate with a frame is provided on the back side of the watch case via a hinge. In the case of using the back surface of the timepiece portion in this way, there is no need to modify the timepiece portion because the front surface of the timepiece case is not affected at all, and the characteristics of a normal timepiece can be left as it is. Therefore, the appearance of the watch case bulges abnormally, the appearance of the watch case becomes unusual, the time reading from the oblique direction becomes difficult, and the design of the watch surface design is largely changed to solve these problems. It is possible to avoid a decrease in the strength of the surface protection plate due to flattening.

Since the back surface of the watch case is a simple surface without any accessories, it is easy to cover the back plate or the back plate with the frame on the back surface of the watch case and fix it with a hinge. Therefore, the difficulty in manufacturing a multifunctional portable timepiece by attaching a back plate with a frame to an existing timepiece is reduced. This also reduces the cost of the product.

Since the back plate or the frame for the back plate also serves as a watch stand, an increase in the number of parts can be suppressed. Therefore, the cost can be reduced by the small number of parts, and the assembling process becomes easy.
