Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band structure and a portable device provided with the same, and more particularly, to a structure of a connection base connected to a main body of the band structure.

[0002]

2. Description of the Related Art In general, a wristwatch comprises a watch body and a band body having a first band portion and a second band portion connected to both sides of the watch body. Leather, cloth, metal, synthetic resin, and the like are used as the material of the band body. Particularly in recent wristwatches, a band body using a synthetic resin (synthetic rubber, urethane-based resin, or the like) having sufficient flexibility and elasticity has been often used.

In the above-mentioned wristwatch band, when the thickness of a connection base connected to the watch body is increased in order to obtain connection strength with the watch body or to give a sense of unity with the watch body. There is.

In particular, in order to obtain a certain strength, a resin band body must be formed to be somewhat thick as a whole, so that the thickness of the connection base is further increased. Also,
Since the resin band can be designed relatively freely by molding techniques such as injection molding, the connection base is almost the same thickness as the watch body in order to increase the integrity of the watch body and the band body. In some cases, it may be formed as thick as about.

[0005]

However, when a band body having a thick connection base is used as described above, the rigidity of the connection base increases, so that the connection base having high rigidity hits the arm and gives a hard feeling. In addition, there is a problem in that the burden on the arm is increased, for example, the wearing feeling is deteriorated.

Further, in the resin band body, there is also a problem that sink is generated at the time of molding in a thickly formed portion, and the shape and dimensions as designed cannot be obtained. At this time,
In order to prevent sink marks on the resin band, a groove (thickness) has been formed on the inner surface of the band (the surface that comes in contact with the arm or wrist) to reduce the substantial thickness and prevent sink marks. There are cases where a method to improve the wearing feeling is adopted,
Even in this case, a part with high rigidity always remains,
It is difficult to greatly improve the wearing feeling and the fit, and depending on the shape, the burden on the arm may be rather increased.

Accordingly, the present invention has been made to solve the above-mentioned problems, and its object is to improve the structure of the connection base of the band body so that the wearing feeling is good and the fit is excellent.
An object of the present invention is to provide a band structure with less burden on an arm.
Another object of the present invention is to provide a band structure capable of ensuring a balance between a feeling of wearing and fitting and an external design.

[0008]

According to a first aspect of the present invention, there is provided a band structure having a connection base connected to an apparatus main body, wherein an inner surface of the connection base is flat. The connection base is formed or curved inward along the band extension direction, and a buffer space is formed inside the connection base.

According to the present invention, the inner surface of the connection base to be connected to the device main body is formed flat, or is provided inside (to the side of the body to be mounted such as a wrist or an arm) along the band extending direction. The inner surface of the band is curved to the inside surface) and the buffer space is formed inside the connection base, so that the inner surface of the band can easily bend in accordance with the body to be mounted due to the presence of the buffer space inside the band. The fit (adhesion) with respect to is improved. Further, even if the connection base is formed thick, the rigidity of the inner surface portion in contact with the object to be mounted is reduced due to the buffer space inside the connection base, so that the feeling of wearing is improved and the burden on the arm can be reduced. Furthermore, since the inner shape of the connection base and the inner space have almost no effect on the outer design, in other words, the inner shape and the inner space can be easily provided regardless of the outer design, so that a feeling of fitting and fitting can be obtained. And the external design can be made compatible at a high level.

A band structure according to a second aspect of the present invention is a band structure having a connection base connected to a device main body, wherein the connection base is formed so as to curve inward along a band extending direction. A buffer space is formed inside the connection base.

According to the present invention, the connection base to be connected to the device main body is curved inward (the inner surface provided on the side of the body to be mounted such as a wrist or an arm) along the extending direction of the band. Since the buffer space is formed inside the connection base, the inner surface of the band can easily bend in accordance with the object to be mounted due to the presence of the buffer space inside, and the elasticity of the curved connection base can be enhanced. Therefore, the fit (adhesion) to the body to be mounted is improved. Further, even if the connection base is formed thick, the rigidity of the inner surface portion in contact with the object to be mounted is reduced due to the buffer space inside the connection base, so that the feeling of wearing is improved and the burden on the arm can be reduced. Furthermore, since the inner shape of the connection base and the inner space have almost no effect on the outer design, in other words, the inner shape and the inner space can be easily provided regardless of the outer design, so that a feeling of fitting and fitting can be obtained. And the external design can be made compatible at a high level.

In the present invention, it is preferable that both the outer surface and the inner surface of the connection base are curved inward along the band extending direction. Since both the outer surface and the inner surface of the connection base are curved inward along the band extending direction, the fit can be improved particularly in a portable device worn on a wrist or an arm such as a wristwatch or a diving computer. In addition, it is possible to configure an external design with a sense of unity between the device main body and the band while reducing the burden on the arm.

In the present invention, it is preferable that the buffer space has a shape curved inward along the band extending direction. Since the buffer space formed inside the connection base is curved inward along the band extending direction, especially in a portable device to be worn on a wrist or an arm, the space shape does not largely collapse even in a worn state. Further, the fit to the wrist and the arm is further improved, and the wearing feeling is further improved.

In the present invention, it is preferable that the buffer space is open on at least one of both sides in the width direction of the connection base. Since the buffer space is opened to the side in the width direction of the connection base, the buffer space is formed to the side, so that the effect of improving the flexibility of the band can be obtained in a wider range in the width direction. . In this case, when the buffer space is open only on one side, it is constituted by a blind hole provided in the connection base. This blind hole structure can be easily formed by molding such as injection molding using a core having a shape corresponding to the blind hole.

In the present invention, it is preferable that the buffer space is open on both sides in the width direction of the connection base. Since the buffer space is open on both sides in the width direction of the connection base, the above-described effect is exerted over the entire width of the connection base. In this case, the buffer space is constituted by a through hole (lateral hole) provided in the connection base. This penetrating structure can be easily formed by molding such as injection molding using a core having a shape corresponding to the through hole.

In the present invention, it is preferable that the thickness of the connection base is increased. If the connection base is thicker than the other parts except the connection base, it is possible to obtain the design integrity with the device main body. And the fit is likely to deteriorate. However, in the present invention, since the buffer space is formed in the connection base, the rigidity of the inner surface of the connection base in contact with the wrist or the like can be reduced and the flexibility can be increased. The improvement effect is particularly high.

In the present invention, it is preferable that the buffer space is configured to reduce a change in thickness of the connection base along a band extending direction. Since the buffer space is configured to reduce the thickness change of the connection base along the band extending direction, the change in the rigidity of the band along the band extending direction is also reduced. , A band structure with high fit can be obtained. Here, the phrase that the buffer space is configured to reduce the thickness change along the band extension direction means that in a place where the thickness of the band is large, the gap in the thickness direction of the buffer space also becomes large, This means that the space in the thickness direction of the buffer space is also reduced in a place where the thickness is small.

In the present invention, it is preferable that a portion between the inner surface of the connection base and the buffer space is formed in an uneven shape along a band extending direction. Since the portion between the inner surface of the connection base and the buffer space is formed in an uneven shape along the band extension direction, the flexibility and flexibility of the connection base can be further increased, and the connection base can be extended in the band extension direction. Can be expanded and contracted, so that it is possible to cope with a situation in which the wrist or arm becomes thinner or thicker due to water pressure during diving, thereby further improving the fit to the wrist or arm.

In the present invention, it is preferable that a portion between the outer surface of the connection base and the buffer space is formed in an uneven shape along the band extending direction. Since the portion between the outer surface of the connection base and the buffer space is formed in an uneven shape along the band extension direction, the flexibility and flexibility of the connection base can be further increased, and the connection base can be extended in the band extension direction. Can be expanded and contracted, so that the fit to a wrist or the like can be further improved. Here, the uneven shape includes all of a wave shape, a fold shape, a bellows structure, and the like.

In the present invention, it is preferable that a tongue-shaped portion extending from the inner surface side of the connection base to the end of the connection base is provided.

A band structure according to a third aspect of the present invention is a band structure having a connection base connected to a device main body, wherein a tongue extending from an inner surface of the connection base to a tip of the connection base is provided. It is characterized by having.

As described above, since the tongue extends from the inner surface of the connection base to the tip of the connection base, the tongue intervenes between the main body of the device and the body to be mounted such as a wrist or an arm. So
Since the object to be mounted is less likely to directly contact the device body, the burden on the arm is reduced, and the feeling of wearing is improved. In addition, when attached to a wrist or an arm, etc. due to the presence of the tongue, the rigidity of the tongue makes the connection base easily bend in accordance with the wrist or the arm, or in another situation, the connection base may As a result, the band shape is adapted to the wrist or the arm by preventing it from being excessively bent, so that the outer shape is improved and the fit is improved. Further, the interposition of the tongue-like portion can enhance the unity between the device and the arm, and can prevent the device from being rotationally displaced with respect to the object to be mounted. Further, since the tongue portion is interposed between the device and the object to be mounted, it is possible to prevent the object to be mounted from directly adhering to the device and thereby deteriorating the feeling of wearing. For example, it is possible to prevent the back cover portion of the watch main body of the wristwatch from sticking to the wrist and to prevent sweat or the like from diffusing, thereby preventing a feeling of wearing from being deteriorated. In addition, it is possible to avoid biting sand between the wrist and the main body of the watch during sea bathing and diving, thereby preventing the wrist and the back cover from being damaged.

In the present invention, the tongue is preferably curved. Since the tongue is curved, it can function as an elastic body between the device and the object when it is interposed between the device and the object, further enhancing the unity between the device and the object. In addition, it is possible to prevent a rotational deviation.

In the present invention, it is preferable that the tongue-shaped portion is curved like a bowl. Since the tongue-shaped portion is curved in a bowl shape, the tongue-shaped portion itself is not easily deformed and the spring property is enhanced, and the space formed by the bowl-shaped portion of the tongue-shaped portion is formed in the device body. Inside surface (when the tongue is curved outward, that is, when the outer surface of the tongue is concave)
Alternatively, by being formed between the outer surface of the body to be mounted (wrist, arm, etc.) (when the tongue is curved inward, that is, when the inner surface of the tongue is concave), air is generated by the space. The effect of the spring is exhibited.

In the present invention, it is preferable that the tongue is curved outward. Since the tongue-shaped portion is curved outward, a cushioning effect on a body to be mounted (a wrist or the like) can be further enhanced, and a feeling of wearing can be improved.

[0026] The portable device of the present invention is characterized in that it has a device main body and a band body having any one of the above-mentioned band structures in which the connection base is connected to the device main body.

In the present invention, it is preferable that the band structures are respectively connected to both sides of the device main body. Bands are connected to both sides of the device main body, and the connection bases on both sides of the device main body both have the above-mentioned structure, so that the wearing feeling is good, the fit is good, and a good external design can be secured. A mounting mode can be realized.

The material of the band body having the band structure is preferably an elastic body to effectively exhibit the above effects, and is preferably a synthetic resin to easily realize the above structure. preferable. Therefore, it is desirable to be made of synthetic resin having elasticity such as synthetic rubber or urethane resin, and it is particularly effective to be formed by molding such as injection molding.

In this specification, the surface that comes into contact with the wrist of the band is simply referred to as “inner surface”, the opposite surface is simply referred to as “outer surface”, the inner surface is simply referred to as “inside”, and the outer surface is simply referred to as “outer surface”. Outside. " Further, the shape of the first band portion 121 is symmetrically formed on both sides of a plane passing through the central axis in the band width direction and orthogonal to the band plane. That is,
In FIG. 2, an outer surface and an inner surface of the first band portion 121 are:
It is represented as a shape symmetrical with respect to a center line S indicated by a chain line.

The connection base 121A of the first band 121
Has a shape curved inward along the band extending direction as a whole, and both the outer surface and the inner surface of the connection base 121A are curved inward. Connection base 1 of first band section 121
A first band portion 1 through which an unillustrated spring bar for connecting to the can of the watch main body 110 is inserted into an end of the first band portion 21A
21 is formed with a connection hole 121a having a circular cross section extending in the width direction. Here, in the following description, a portion where the connection hole 121a is formed is simply referred to as a “connection end”.

The connection hole 1 in the connection base 121A
A buffer space 121b extending in the band width direction is provided closer to the band-like portion 121B than the band 21a. This buffer space 1
21b has a cross-sectional shape substantially corresponding to the thickness of the connection base 121A. That is, the buffer space 121b has such a shape that the gap width in the band thickness direction is large in the thick portion of the connection base 121A, and the gap width in the band thickness direction is small in the thin portion of the connection base 121A. The buffer space 121b has a curved shape corresponding to the curved shape of the connection base 121A. The buffer space 121b penetrates in the band width direction and has openings on both sides of the band. The cross section of the buffer space 121b in the band width direction has a substantially constant shape as a whole.

A concave-convex region 121c having a wavy shape along the band extending direction is provided on an inner portion (a portion between the inner surface and the buffer space) of the connection base 121A. The uneven area 121c is formed only in the inner part of the buffer space 121b.

The connection hole 1 in the connection base 121A
The tongue-like portion 12 is provided inside the connection end portion 21a so as to protrude (leftward in the drawing) beyond the connection end portion.
1d is provided. FIG. 3 shows a state in which the tongue portion is viewed from the lower right of FIG. 1 in the center of the tongue portion 121d.
As shown in FIG. 3 (b) and FIG. 3 (c) showing a state in which the tongue portion is viewed obliquely from the upper left side, a curved portion 121e is formed on the outer surface side of the band, and the outer surface of the curved portion 121e is The inner surface of the curved portion 121e is configured to have a convex curved surface.

On the inner surface of the first band portion 121, a concave groove 121f is formed extending from the connection base 121A to the band portion 121B at the center in the width direction. This groove 1
21f has a widened and deepened shape in the band width direction at the connection base 121A. The concave groove 121f is a groove for preventing the occurrence of sink marks during molding of the first band portion 121 and increasing the molding accuracy, and is also a groove for improving the sweat-releasing effect. The concave groove 121f is formed in the connection base 121A so as to substantially equalize the substantial thickness of the connection base 121A together with the buffer space 121b as a whole. That is, the buffer space 1 in the connection base 121A.
The concave groove 121f reduces the thickness of the connection base 121A in the portion where the portion 21b is not formed. Note that the cross-sectional shape of the band-shaped portion 121B is shown in FIG.

On the other hand, the connection base 12 of the second band 122
2A and the band portion 122B are formed by the first band portion 121 described above.
And the same structure as the connecting base 121A and the band-shaped portion 121B. Part of the second band section 122 is shown in FIG. In the second band portion 122, a connection base 122A similar to the above is provided with a connection hole 122 similar to the above.
a, a buffer space 122b, an uneven area 122c, and a tongue 122d. A curved portion 122e similar to the above is formed on the tongue-shaped portion 122d.

In the present embodiment having the above-described structure, the thick connecting bases 121A and 122A are curved inward as a whole, so that the timepiece main body 1 is formed.
The external design from 10 to the band body 120 is configured to emphasize the integrity of the watch main body 110 and the band body 120, and also enhances the fit to the wrist and the arm. Here, the buffer space 1 is provided in the connection base 121A.
Due to the formation of 21b, the substantial thickness of the connection base 121A formed thick is reduced, the connection base 121A is easily curved, the elasticity is enhanced, and the connection base 121A has sufficient flexibility. Therefore, it is configured such that adhesion and fit to the wrist are improved.

Further, due to the existence of the buffer space 121b, the thinly formed portion between the buffer space 121b and the inner surface is softened, so that the feeling of wearing is improved and the burden on the arm is reduced. I have.

Here, the strength of the connection base 121A is determined by the sum of the thicknesses on the outside and inside of the buffer space. Therefore, according to the present embodiment, the band strength is not reduced (regardless of the band strength). By reducing the thickness of the inside of the buffer space, it is possible to improve the feeling of fitting and the fit.

Since the concave-convex region 121c is provided on the inner surface of the connection base 121A, the connection base 121A is provided.
Since A is easily curved and has elasticity, it is possible to further improve the fit to the wrist and the arm.
Further, since the uneven shape area 121c is formed as a part of the inner surface of the band, a gap due to the uneven shape is formed between the uneven shape area 121c and the skin surface of the wrist, and air exists in the gap. Acts to allow sweat to escape from the gap. Therefore, it is possible to prevent the skin surface of the wrist from being in intimate contact with the uneven region 121c, or prevent sweat from accumulating without escaping, thereby deteriorating the feeling of wearing.

Further, in the present embodiment, the connection base 121
A tongue-like portion 121d extending ahead of the connection end is provided on the inner surface side of the connection end of A, so that the tongue-like portion 121d comes into contact with the wrist so as to exert an elastic force on the wrist. ,
Since the integration between the wrist and the wristwatch is enhanced, it is possible to reduce problems such as the wristwatch (band body 120) being rotated with respect to the wrist. The tongue-shaped portion 121d also has the effect of making the curved shape of the connection base 121A with respect to the wrist and the arm and an appropriate bending angle with respect to the watch main body 110, so that the outer shape of the wristwatch can be adjusted. Further, since the tongue is inserted between the watch main body 110 and the wrist or arm,
The wrist or the arm can be prevented from directly contacting the back cover of the watch main body 110. Here, when the watch main body 110 is made of metal, when the back cover portion is formed flat, or the like, the wrist or the arm does not contact the back cover portion, so that the feeling of wearing can be improved. .

[Another Configuration Example of Buffer Space] FIG. 5 shows a configuration example of a connection base having another shape different from the connection base of the above embodiment. Note that, in these configuration examples, the uneven shape region 12 provided in the above-described embodiment is used.
1c and the tongue-shaped portion 121d are not formed.

The connection base 131A of the first band 131 shown in FIG. 5A has a connection hole 131a and a buffer space 131b similar to those described above. At this time, although the connection base 131A is formed to be thicker in appearance than the portion other than the connection base 131A (the above-mentioned band-shaped portion), the substantial thickness is reduced by forming the buffer space 131b. It is formed so as to be almost the same as the portion other than the base 131A. In this configuration example, the connection base 131A is slightly curved as a whole on the inner surface side, and the outer surface of the connection base 131A is curved on the inner surface side, but the inner surface of the connection base 131A is formed substantially flat. ing.

The connection base 141A of the first band portion 141 shown in FIG.
Two buffer spaces 141b-1 arranged in the band extending direction,
141b-2 are formed. By forming a plurality of buffer spaces in the band extending direction as described above, the flexibility, fitting property, and flexibility of the connection base similar to the above can be widened by the buffer space while preventing the shape of the connection base 141A from being lost. Can be increased. In addition, this connection base 1
The curved shape of 41A is the connecting base 131A shown in FIG.
Is the same as

The connection base 151A of the first band 151 shown in FIG. 5C has a connection hole 151a similar to that described above.
Two buffer spaces 151b-1, arranged in the band thickness direction,
151b-2 are formed. By forming a plurality of buffer spaces in the band thickness direction as described above, the shape of the connection base 151A can be prevented from being out of shape, and the flexibility of the connection base can be improved.
The fit and flexibility can be greatly increased as compared with the case where a single buffer space is formed. In particular, connection base 1
By forming the plurality of buffer spaces in the thickness direction when the thickness of the 51A is formed thickly, the flexibility of the inner surface portion with which the wrist contacts can be greatly increased, and a very soft and good wearing feeling can be realized. In addition, this connection base 151A
Is also the same as the connection base 131A shown in FIG.

FIG. 6 shows a state where the first band portion 131 and the second band portion 132 are attached to the watch main body 110. As shown in FIG. 6A, buffer spaces 131b, similar to those shown in FIG. 5A are provided in connection bases 131A and 132A of the first band portion 131 and the second band portion 132.
132b are respectively formed. When such a wristwatch is mounted on the wrist 10, as shown in FIG. 6B, the buffer spaces 131b and 132b are crushed, so that the inner surfaces of the connection bases 131A and 132A, which are almost flat, curve inward, and The connection base 131A corresponding to the outer shape of No. 10
132A flexes flexibly. This is the connection base 1
The flexibility of the buffer spaces 131b and 132A
This is because b is increased by being formed.
In addition, the feel of the connection bases 131A and 132A received by the wrist 10 is softened mainly by the flexibility of the inner portions of the buffer spaces 131b and 132b.

[Example of Configuration of Concavo-convex Region] Next, FIG.
With reference to (a) and (b), another configuration example different from the above-described embodiment in the case where an uneven region is added to the connection base where the buffer space is formed will be described. FIG. 7 (a)
In the connection base 161A of the first band portion 161 shown in FIG. 1, a connection hole 161a similar to the above and a buffer space 161b having a cross section different from the above are provided. Also,
A corrugated uneven region 161c is formed in an outer portion (a portion between the buffer space 161b and the outer surface) of the connection base 161A along the band extending direction. The thickness of the uneven region 161c is substantially constant along the band extending direction regardless of the wave shape. This is because the cross-sectional shape of the buffer space 161b has a cross-sectional shape that matches the wavy shape of the inner surface of the uneven region 161c.

As described above, even when the uneven region 161c is formed outside the connection base 161A, the flexibility and flexibility of the connection base 161A can be increased. Since the thickness of the uneven region 161c is substantially constant along the band extending direction as in this configuration example, the flexibility and flexibility of the outer surface side portion of the connection base 161A can be significantly improved. Can be. In this configuration example, the thickness of the inner portion (portion between the inner surface and the buffer space 161b) of the connection base 161A is also substantially constant along the band extending direction, so that the flexibility of the connection base 161A as a whole is increased. Sex and flexibility have increased significantly.

The connection base 171A of the first band 171 shown in FIG. 7B has a connection hole 171a similar to the above and a meandering buffer space 171b curved in the band thickness direction. An uneven area 171c is formed outside the connection base 171A. The uneven region 171c has a wavy shape substantially corresponding to the shape of the meandering buffer space 171b, so that the thickness between the outer surface of the connection base 171A and the buffer space 171b in the uneven region 171c is extended by the band. The direction is almost constant.

In the connection base 171A, the inner surface is slightly curved inward while the buffer space 171b is provided.
Is formed in a meandering shape as described above, so that it is easy to bend inward as a whole.
The structure is slightly higher in rigidity than the connection base 161A shown in FIG.

As described above, the concavo-convex shape to be formed in the present invention can be applied to the connection base portion regardless of whether it is formed on the inside portion or the outside portion as long as it corresponds to the portion where the buffer space is formed. This can contribute to an increase in flexibility and flexibility. However, only when it is formed on the inner surface of the connection base, an additional effect that it is possible to avoid the close contact between the inner surface and the skin of the wrist and the stagnation of sweat can be obtained.

[Example of Configuration of Tongue] Next, an example of a configuration in which a tongue is formed on the connection base will be described with reference to FIGS. 7 (c) and 7 (d). The formation of the tongue portion in the connection base has an effect even when an internal space such as a buffer space is not formed, but the following configuration example will describe a case where a buffer space is additionally provided. .

As shown in FIG. 7C, the first band 1
In the connection base 181A, a connection hole 18 similar to the above is provided.
1a, a buffer space 181b having substantially the same shape as that shown in FIG. 5A, and a connection hole 18 from the inner side of the connection base 181A.
Tongue 18 extending beyond the formed connection end of 1a
1d are formed. The tongue-shaped portion 181d projects from the inner surface of the connection base 181A in a slightly curved shape.

In the first band portion 191 shown in FIG. 7D, the connection base 191A curves inward as a whole similarly to the above embodiment, and both the outer surface and the inner surface of the connection base 191A curve inward. I have.

Curved portion 1 between tongue portions 191d, 192d and back cover
Since the space defined by 91e and 192e exists, the tongue portions 191d and 192d can be interposed between the watch main body 110 and the wrist 10 without losing the function as an elastic body. In addition, there is also an effect of enhancing sweat escape properties and improving a feeling of wearing.

It should be noted that the band structure of the present invention is not limited to the illustrated example described above, and it is needless to say that various changes can be made without departing from the scope of the present invention. For example, the above embodiment relates to a wristwatch, but the present invention is not limited to a wristwatch, and can be widely used as a band structure for connecting to various device bodies.

In the above description, the buffer space formed in the connection base has a hole shape penetrating in the band width direction. However, this buffer space has a blind hole shape with one side closed. Alternatively, it may be a closed space whose periphery is almost completely closed.

Further, the buffer space is merely for improving the wearing feeling and the fit at the connection base, and is merely a connection hole used for connection with the (watch) body itself, the spring bar, or the beautiful lock. And engagement holes. However, for example, when the buffer space is configured to communicate with the connection hole, or when the connection hole is extended and a part thereof is configured to function as the buffer space, the band structure is used. Is included in the scope of the present invention.
