Detailed Description
An embodiment in which the present invention is applied to a wristwatch will be described below with reference to fig. 1 to 4(a) and 4 (b).
As shown in fig. 1, the wristwatch includes a wristwatch case 1. The watch case 1 is provided with a band attachment portion 2 on each of the 12 o 'clock side and the 6 o' clock side. The switching devices 3 are provided on the 2 o ' clock side, the 3 o ' clock side, the 4 o ' clock side, the 8 o ' clock side, and the 10 o ' clock side of the wristwatch case 1, respectively.
In this case, as shown in fig. 2, the wristwatch case 1 includes a main body case 4 and a bezel case 5. The main body case 4 is made of metal such as stainless steel or hard synthetic resin. The bezel case 5 covers the outer periphery of the main body case 4, and is formed of a soft synthetic resin such as a urethane resin.
As shown in fig. 2, a watch glass 6 is attached to the upper opening of the watch case 1, that is, the upper opening of the main body case 4, via a glass gasket 6 a. A back cover 7 is attached to a lower portion of the watch case 1, that is, a lower portion of the main body case 4, via a cover gasket 7 a.
As shown in fig. 2, a timepiece module 10 is housed inside the wristwatch case 1, that is, inside the main body case 4. The timepiece module 10 includes various components necessary for a timepiece function, such as a timepiece movement for operating hands to instruct time, a flat display panel for electro-optically displaying information such as time, and a circuit board for driving and controlling the components, but not shown.
However, as shown in fig. 2, for example, the switching device 3 on the 2-point side among the plurality of switching devices 3 of the wristwatch case 1 includes: an operation member 12 attached to a through hole 11 provided in the main body case 4 of the wristwatch case 1; and a cushion body 13 disposed between an outer surface of the main body case 4 and a head 16 of the operation member 12, which will be described later, and having elasticity.
In this case, as shown in fig. 2, the main body case 4 is provided with a housing recess 14 for disposing the cushion body 13 corresponding to the through hole 11. The housing recess 14 is formed in a substantially elongated shape that is long in the circumferential direction of the main body case 4, and is formed in a size that the length in the width direction orthogonal to the longitudinal direction thereof is larger than the inner diameter of the through hole 11 and smaller than the outer diameter of a head 16 of the operating member 12, which will be described later.
As shown in fig. 2, the operating member 12 includes a shaft portion 15 slidably inserted into the through hole 11 of the main body case 4, and a head portion 16 provided at an outer end of the shaft portion 15 and disposed outside the main body case 4. The shaft portion 15 is formed so that the outer diameter is substantially the same as the inner diameter of the through hole 11 of the main body case 4, and the axial length is longer than the wall thickness of the main body case 4, that is, the axial length of both the through hole 11 and the accommodation recess 14.
Thus, as shown in fig. 2, when inserted into the through hole 11 of the main body case 4, the shaft portion 15 has an inner end portion projecting into the main body case 4 and an outer end portion projecting from the housing recess 14 to the outside of the main body case 4. In this case, the shaft portion 15 is attached with a retaining member 17 such as an E-ring at an inner end portion protruding into the main body case 4. The retaining member 17 is configured to come into contact with the inner circumferential surface of the main body case 4 so as to be able to approach and separate from the inner circumferential surface of the main body case 4, and thus the shaft portion 15 is not removed from the main body case 4 to the outside.
As shown in fig. 2, the shaft portion 15 is provided with a plurality of waterproof rings 18 on the outer peripheral surface at positions inserted into the through-hole 11 of the main body case 4, and the plurality of waterproof rings 18 are configured to slide while being pressed against the inner peripheral surface of the through-hole 11. With this configuration, even if the shaft portion 15 slides in the through hole 11, the inner circumferential surface of the through hole 11 and the outer circumferential surface of the shaft portion 15 can be waterproofed by the plurality of waterproof rings 18.
As shown in fig. 2, the head portion 16 of the operating member 12 is formed in a substantially cylindrical shape, and the outer end portion of the shaft portion 15 is integrally provided on the inner end surface thereof. The head 16 is formed to have an outer diameter slightly larger than the length of the housing recess 14 of the main body case 4 in the width direction. The head portion 16 is formed to have an axial length substantially equal to that of the through hole 11 of the body case 4, slightly longer than that of the housing recess 14, and longer than the thickness of the outer peripheral portion of the bezel case 5.
Thus, as shown in fig. 2, the head 16 is disposed outside the body case 4, and the outer end thereof projects outward from the bezel case 5. Therefore, the head portion 16 is configured to be able to easily and satisfactorily perform the opening and closing operation from the outside of the bezel housing 5. In this case, the timepiece module 10 in the main body case 4 includes the switch portion 19, and when the head portion 16 of the operating member 12 is pressed and the inner end portion of the shaft portion 15 is pressed into the main body case 4, the switch portion 19 performs a switching operation by the inner end portion of the shaft portion 15.
As shown in fig. 2, the switch unit 19 includes a switch main body 19a and a plate spring-like contact plate 19b that is pressed against the switch main body 19a so as to be able to approach to and separate from the switch main body 19 a. Thus, the switch section 19 is configured such that the contact plate 19b is pressed by the inner end portion of the shaft portion 15 and pressed against the switch main body 19a to perform an on operation, and when the inner end portion of the shaft portion 15 slides toward the outside of the main body case 4, the contact plate 19b is separated from the switch main body 19a and is turned off.
However, as shown in fig. 2 to 4(a) and 4(b), the cushion body 13 is formed by wrapping a gel-like material 20 having an expansion characteristic with an elastic material 21, and is disposed in the housing recess 14 of the main body case 4 with elasticity. In this case, the cushion body 13 is formed to have a size larger than the head 16 of the operation member 12 in order to allow the gel-like material 20 to exhibit the swelling property.
Therefore, as shown in fig. 2, the storage recess 14 of the main body case 4 is also formed so that the length in the longitudinal direction thereof is larger than the outer diameter of the head 16. The axial length (thickness) of the shaft portion 15 is formed to be longer than the axial length (depth) of the housing recess portion 14, and thus the buffer body 13 is configured to protrude from the housing recess portion 14 to the outside of the main body case 4 when disposed in the housing recess portion 14.
As shown in fig. 2 and 4(b), in the case of the gel-like material 20 having swelling properties, when the operating member 12 performs a switching operation of the switch unit 19 with a pressing force of such a degree that the elastic member 21 is elastically deformed, the material 20 is elastically deformed, and when a strong force such as an impact is applied, the material 20 becomes hard and does not deform. That is, the gel-like raw material 20 has low rebound with respect to a low impact, that is, a lower frequency impact, and is elastically deformed slowly as a liquid, and has high rebound with respect to a high impact, that is, a higher frequency impact, and the elastic force is reduced, and becomes hard as a solid without being deformed.
Therefore, as shown in fig. 2 and 4(b), when the gel-like material 20 is pressed with a low impact, that is, with a pressing force of such a degree that the operating member 12 performs the opening and closing operation of the switch unit 19, the amount of deformation of the material 20 by elastic deformation is set within the range of the length (S1 to S2) of the difference between the operating stroke S1 of the operating member 12 and the operating stroke S2 of the switch unit 19.
On the other hand, as shown in fig. 2 to 4(a) and 4(b), the elastic member 21 is an outer peripheral film covering the gel-like material 20, and is a material having an elastic force such as silicone rubber, urethane rubber, or elastomer, and preferably silicone rubber. The elastic member 21 is configured to have a function as a spring member by being elastically deformed within the range of the operation stroke S1 of the operation member 12. That is, the elastic member 21 is configured to be pressed by the head portion 16 of the operating member 12 to be elastically deformed, and to restore the operating member 12 to its original state by a restoring force of the elastic deformation.
As shown in fig. 2 to 4(a) and 4(b), the elastic member 21 is formed in a rectangular box shape having the same size as the outer shape of the cushion body 13, and a gel-like material 20 is sealed inside the box shape. In this case, the elastic member 21 has a structure in which a cylindrical portion 21a for inserting the shaft portion 15 into the central portion inside is provided. The cylindrical portion 21a is formed to have an inner diameter larger than the outer diameter of the shaft portion 15.
As shown in fig. 2 to 4(a) and 4(b), the elastic member 21 includes a first outer wall portion 21b, which is a side wall parallel to the sliding direction of the shaft portion 15 of the operation member 12, and a second outer wall portion 21c, which is a pair of flat plates orthogonal to the sliding direction of the shaft portion 15. The first outer wall portion 21b is formed to have a wall thickness larger than that of the second outer wall portion 21 c. In this case, of the pair of flat plate-like second outer wall portions 21c, the second outer wall portion 21c located on the head portion 16 side of the operating member 12 is formed to have a smaller wall thickness than the second outer wall portion 21c located on the bottom portion side of the housing recess 14.
As shown in fig. 2 to 4(a) and 4(b), the cylindrical portion 21a of the elastic member 21 is formed to have a thickness substantially equal to that of the first outer wall portion 21 b. The cylindrical portion 21a and the first outer wall portion 21b of the elastic member 21 are set to have a larger deformation amount when the cushion body 13 is pressed by the head portion 16 of the operating member 12 than the deformation amount of the gel-like material 20 having the expansion characteristic.
As a result, as shown in fig. 2 to 4(a) and 4(b), when the cushion body 13 is pressed by the head portion 16 of the operating member 12 and the first outer wall portion 21b and the cylindrical portion 21a of the elastic material 21 are elastically deformed and the gel-like material 20 is elastically deformed like a liquid, the shaft portion 15 reliably presses the switch portion 19 and the switch portion 19 is turned on by the deformation amounts of the cylindrical portion 21a, the first outer wall portion 21b, and the gel-like material 20.
In this case, as shown in fig. 2 to 4(a) and 4(b), when the shaft portion 15 of the operating member 12 is separated from the opening/closing portion 19, the cylindrical portion 21a and the first outer wall portion 21b of the elastic member 21 elastically recover to return to their original shapes, and the gel-like material 20 elastically recovers to its original shape with a delay and a slowness compared to the elastic recovery of the elastic member 21, whereby the operating member 12 is pushed out toward the outside of the main body case 4 and returned to its original state.
As shown in fig. 2 to 4(a) and 4(b), the shock absorber 13 is configured such that, even if the cylindrical portion 21a and the first outer wall portion 21b of the elastic material 21 are rapidly elastically deformed when the head portion 16 of the operating member 12 receives a strong force such as an impact from the outside, the gel-like material 20 becomes hard as a solid and is not substantially deformed, and the inner end portion of the shaft portion 15 of the operating member 12 is not largely pressed into the main body case 4. Therefore, the switch unit 19 is configured not to perform the closing operation even if the contact plate 19b is pressed by the shaft portion 15 of the operating member 12.
In this case, as shown in fig. 2 to 4(a) and 4(b), since the gel-like material 20 is not substantially deformed when the shaft portion 15 of the operating member 12 is separated from the opening/closing portion 19, the cylindrical portion 21a and the first outer wall portion 21b of the elastic member 21 are returned to their original shapes by elastic recovery, and the operating member 12 is pushed out toward the outside of the main body case 4 and returned to its original state by the buffer 13.
As shown in fig. 2, the opening and closing device 3 has a structure in which a gap R for allowing deformation of the buffer 13 is provided between the outer peripheral surface of the buffer 13 and the inner peripheral surface of the storage recess 14 of the main body case 4. The gap R is configured such that, when the cushion body 13 is pressed and compressed by the head portion 16 of the operating member 12, the cushion body 13 is elastically deformed so as to expand in a radial direction orthogonal to the axial direction of the shaft portion 15, and the volume of the gel-like material 20 having the expansion characteristic is not compressed.
As shown in fig. 2, the switch device 3 has a structure in which a hard plate 22 for transmitting the pressing force of the head portion 16 to the entire buffer body 13 is disposed between the buffer body 13 and the head portion 16 of the operating member 12. The plate 22 is formed in a flat plate shape from a metal such as stainless steel or a hard synthetic resin. The plate 22 is formed to have an outer shape equal to or slightly larger than the outer shape of the cushion body 13, and is configured to have an insertion hole 22a in the center into which the shaft portion 15 is inserted.
Thus, as shown in fig. 2, when the inner end surface of the head portion 16, which is the pressing region of the head portion 16 of the operating member 12, is pressed, the plate 22 is pressed against the outer surface of the cushion body 13 facing the plate 22, that is, the entire second outer wall portion 21c of the elastic member 21, so that even if both sides of the cushion body 13 in the longitudinal direction protrude from the head portion 16, the cushion body 13 is not locally deformed, and the cushion body 13 is uniformly pressed over the entire cushion body 13, and the entire cushion body 13 is uniformly deformed. In this case, even if both sides of the plate 22 in the longitudinal direction protrude beyond the head portion 16, the plate 22 is covered by the bezel case 5 so as not to be visible from the outside.
As shown in fig. 2 to 4(a) and 4(b), a plurality of elastic protrusions 23 are provided on the second wall portion 21c of the elastic member 21 facing the bottom surface of the housing recess 14 so as to protrude in the sliding direction of the shaft portion 15 of the operating member 12. The plurality of elastic projections 23 are provided on an end surface of the second wall portion 21c facing the bottom surface of the storage recess 14 of the main body case 4.
In this case, as shown in fig. 4(b), concave portions 23a corresponding to the plurality of elastic protrusions 23 are provided on the inner surface of the second wall portion 21c of the elastic member 21. Thus, when the head portion 16 of the operating member 12 is pressed from the outside, the plurality of elastic protrusions 23 are configured such that the elastic protrusions 23 are pressed against the bottom surface of the accommodating recess 14, and in this state, both the cylindrical portion 21a and the first outer wall portion 21b of the elastic member 21 are elastically deformed. The plurality of elastic protrusions 23 are configured to prevent the cushion body 13 from loosening when disposed in the housing recess 14.
Next, the operation of the switch device 3 of the wristwatch will be described.
When the switch device 3 is in the normal initial state, the operating member 12 is pushed out of the main body case 4 of the wristwatch case 1 by the elasticity of the buffer 13. That is, the head portion 16 of the operating member 12 is pushed out of the main body case 4 by the spring force generated by the spring force of the elastic material 21 of the shock absorber 13, that is, the cylindrical portion 21a, the first outer wall portion 21b, and the plurality of elastic protrusions 23 of the elastic material 21, and the stopper member 17 provided at the inner end portion of the shaft portion 15 is pressed against the inner surface of the main body case 4.
In this state, the inner end portion of the shaft portion 15 of the operating member 12 is separated from the switch portion 19 of the timepiece module 10, and therefore the switch portion 19 is turned off. In this state, the head portion 16 of the operating member 12 is pushed out of the body case 4 together with the plate 22, and the outer end portion of the head portion 16 protrudes out of the bezel case 5. Therefore, in the switch device 3, the operability when the head portion 16 of the operating member 12 is operated is improved, and the operation can be performed well and easily.
When the switch unit 19 is turned on by operating the switch device 3, the head portion 16 of the operating member 12 is pressed against the elastic force of the elastic member 21 of the cushion body 13. That is, when the head 16 is pressed with a pressing force of such a degree that the switch unit 19 performs a switching operation, that is, with a low impact force, the inner end surface of the head 16, which is a pressing region of the head 16, presses the cushion body 13 via the plate 22.
In this way, in response to the pressing operation of the head 16, the cylindrical portion 21a, the first outer wall portion 21b, and the plurality of elastic protrusions 23 of the elastic member 21 are elastically deformed by the plate 22, and the gel-like material 20 is elastically deformed slowly like a liquid. At this time, since the plate 22 is pressed by the head portion 16 and the cushion body 13 is pressed by the plate 22, even if both sides of the cushion body 13 in the longitudinal direction protrude from the head portion 16, the cushion body 13 is not locally deformed and the entire cushion body 13 is uniformly pressed.
Thereby, the shaft portion 15 of the operating member 12 slides in the through hole 11 of the main body case 4 and the cylindrical portion 21a of the buffer 13, and the inner end portion of the shaft portion 15 protrudes into the main body case 4. At this time, the retaining member 17 provided at the inner end portion of the shaft portion 15 is separated from the inner peripheral surface of the main body case 4, and the inner end portion of the shaft portion 15 presses the contact plate 19b of the switch portion 19 of the timepiece module 10 and presses the contact plate 19b to the switch main body 19 a. The switch portion 19 is pressed by the shaft portion 15 to perform a closing operation.
In this state, when the operation member 12 returns to the initial state, the cylindrical portion 21a, the first outer wall portion 21b, and the plurality of elastic protrusions 23 of the elastic material 21 elastically recover to return to the original shape, and the gel-like material 20 elastically recovers to the original shape with a delay and a slowness compared to the elastic recovery of the elastic material 21. The head portion 16 of the operating member 12 is thereby pushed out of the main body case 4 together with the plate 22. Then, the inner end portion of the shaft portion 15 is separated from the opening/closing portion 19 of the timepiece module 10, the opening/closing portion 19 is turned off, and the operation member 12 is returned to the initial state by pressing the retaining member 17 of the inner end portion of the shaft portion 15 against the inner peripheral surface of the main body case 4.
On the other hand, when the head portion 16 of the operating member 12 receives a strong force such as an external impact, even if the cylindrical portion 21a, the first outer wall portion 21b, and the plurality of elastic protrusions 23 of the elastic material 21 are rapidly elastically deformed by the high impact, the gel-like material 20 becomes hard as a solid and is not substantially deformed, so that the inner end portion of the shaft portion 15 of the operating member 12 is not largely pressed into the main body case 4. Therefore, even if the contact plate 19b of the switch unit 19 is pressed by the shaft portion 15 of the operating member 12, the contact plate 19b is not pressed against the switch main body 19a, and the on operation is not performed. This can prevent the timepiece module 10 in the main body case 4 from being damaged.
In this state, when the operating member 12 returns to the initial state, the gel-like material 20 is not substantially deformed, and therefore the cylindrical portion 21a, the first outer wall portion 21b, and the plurality of elastic protrusions 23 of the elastic member 21 elastically recover to return to the original shape. The head portion 16 of the operating member 12 is thereby pushed out of the main body case 4 via the plate 22, and the inner end portion of the shaft portion 15 is separated from the contact plate 19b of the switch portion 19 of the timepiece module 10. Therefore, in a state where the opening and closing portion 19 is maintained in the off state, the retaining member 17 of the inner end portion of the shaft portion 15 is pressed to the inner peripheral surface of the main body case 4, and the operation member 12 is returned to the initial state.
As described above, according to the switch device 3 of the wristwatch, operability can be ensured and damage to the timepiece module 10 by an impact can be prevented by providing the main body case 4, the operating member 12, and the cushion body 13, wherein the main body case 4 is provided with the through hole 11 corresponding to the internal switch portion 19, the operating member 12 is provided with the shaft portion 15 slidably inserted into the through hole 11 of the main body case 4, and the head portion 16 provided at the outer end of the shaft portion 15 and disposed outside the main body case 4, and the cushion body 13 is formed by wrapping the gel-like material 20 having expansion characteristics with the elastic material 21 and disposed between the head portion 16 and the main body case 4.
That is, in the switch device 3, when the switch unit 19 is turned on by pressing the head portion 16 of the operating member 12 with a low pressing force to the extent that the elastic material 21 of the cushion body 13 is elastically deformed, the elastic material 21 of the cushion body 13 is elastically deformed and the gel-like material 20 of the cushion body 13 is elastically deformed like a liquid, so that the switch unit 19 in the main body case 4 can be reliably and satisfactorily turned on by the shaft portion 15 of the operating member 12, and operability can be ensured.
In the switch device 3, when the head portion 16 of the operating member 12 receives a strong force such as an impact from the outside of the main body case 4, even if the elastic member 21 is rapidly elastically deformed, the gel-like material 20 becomes hard as a solid and hardly deforms, and the inner end portion of the shaft portion 15 of the operating member 12 is not largely pressed into the main body case 4. Therefore, the switch portion 19 is not turned on by the shaft portion 15 of the operating member 12, and the timepiece module 10 in the main body case 4 is not damaged by the shaft portion 15.
In this case, the head portion 16 of the operating member 12 is provided so as to protrude outward from the bezel case 5 covering the outer periphery of the main body case 4 in a state of being disposed outside the main body case 4, whereby the head portion 16 can be easily and satisfactorily operated, and operability can be improved. By projecting the head portion 16 to the outside of the bezel case 5 in this manner, the size and shape of the head portion 16 can be freely set, and the design of the entire wristwatch can be improved.
In this switch device, the head portion 16 of the operating member 12 includes the inner end surface of the head portion 16, which is a pressing region for transmitting the pressing force to the cushion body 13, and the inner end surface of the head portion 16, which is the pressing region, corresponds to the cross section of the cushion body 13 perpendicular to the shaft portion 15, so that the pressing force of the head portion 16 can be transmitted to the cushion body 13 reliably and satisfactorily by the inner end surface of the head portion 16, which is the pressing region of the head portion 16, after the head portion 16 is pressed.
In this case, by arranging the plate 22 for transmitting the pressing force of the head 16 over the entire cushion body 13 between the cushion body 13 and the inner end surface of the head 16, which is the pressing region of the head 16 of the operation member 12, when the head 16 is pressed and the inner end surface of the head 16 is pressed against the plate 22, the plate 22 can be pressed against the entire outer surface of the cushion body 13 facing the plate 22.
Therefore, in this switch device, even if both sides of the cushion body 13 in the longitudinal direction protrude beyond the inner end surface of the head portion 16, which is the pressing region of the head portion 16, the cushion body 13 is not locally deformed, and the cushion body 13 is uniformly pressed over the entire cushion body 13, so that the entire cushion body 13 can be uniformly and satisfactorily deformed.
In this case, when the gel-like material 20 of the cushion body 13 is deformed like a liquid, the elastic member 21 is pressed by the head portion 16 of the operation member 12 and elastically deformed within the range of the operation stroke of the operation member 12, and the operation member 12 is restored to the original state by the restoring force of the elastic deformation, whereby the elastic member 21 can function as a spring member, and can be used as in a normal switch device, and a switch device having excellent usability can be provided.
Further, when the operating member 12 is operated to open and close the switch portion 19 with a low pressing force to the extent that the elastic member 21 is elastically deformed, the material 20 is elastically deformed like a liquid, and when a strong force such as an impact is applied, the material 20 becomes hard like a solid and is not substantially deformed, whereby the operability of the operating member 12 can be ensured, and damage to the switch portion 19 and the timepiece module 10 due to the impact can be prevented.
That is, the gel-like material 20 having swelling properties has low rebound with respect to a low impact, that is, an impact of a relatively low frequency, and is elastically deformed slowly as a liquid, and has high rebound with respect to a high impact, that is, an impact of a relatively high frequency, and the elastic force is reduced, and becomes hard as a solid and is not substantially deformed, so that when the operating member 12 is pressed with a pressing force of a low impact to the extent that the switch unit 19 performs a switching operation, the elastic member 21 elastically deforms together with the material, and the switch unit 19 can perform a good on operation.
In the gel-like material 20, even if the elastic member 21 is elastically deformed when the head portion 16 of the operating member 12 receives a high impact such as an impact, the material 20 is highly rebounded against the impact, the elastic force is reduced, and the material becomes hard as a solid and is not substantially deformed, so that the off state can be maintained without turning on the switch unit 19, and thus, the impact resistance can be ensured, and the switch unit 19 and the timepiece module 10 can be prevented from being damaged by the high impact.
That is, in the switch device 3, when the head portion 16 of the operating member 12 is pressed to perform a switching operation, the gel-like material 20 and the elastic material 21 are elastically deformed like a liquid, so that the shaft portion 15 can press the switch portion 19 to perform an on operation, and when the shaft portion 15 of the operating member 12 is separated from the switch portion 19, the elastic material 21 elastically restores to return to an original shape, and the gel-like material 20 elastically restores to return to the original shape with a delay and a slow delay from the elastic restoration of the elastic material 21, so that the operating member 12 can be pushed out toward the outside of the main body case 4 to return to an original state.
In the switch device 3, even if the elastic member 21 is rapidly elastically deformed when the head portion 16 of the operating member 12 receives a strong force such as an external impact, the gel-like material 20 becomes hard as a solid and hardly deforms, and the shaft portion 15 of the operating member 12 is not pressed into the main body case 4 to a large extent, whereby the switch portion 19 is not turned on, and the switch portion 19 and the timepiece module 10 can be prevented from being damaged.
In this case, in the switch device 3, when the shaft portion 15 of the operating member 12 is separated from the switch portion 19, since the gel-like material 20 is not substantially deformed, only the elastic member 21 is elastically restored to return to its original shape, and the operating member 12 can be pushed out toward the outside of the main body case 4 to return to its original state.
When the gel-like material 20 having swelling properties is solid, the cushion body 13 is deformed within the range of the difference (S1 to S2) between the operation stroke S1 of the operating member 12 and the operation stroke S2 of the switch unit 19, so that when the operating member 12 is pressed to perform a switching operation, the gel-like material 20 and the elastic member 21 can be elastically deformed like a liquid within the range of the difference between the operation stroke S1 of the operating member 12 and the operation stroke S2 of the switch unit 19, and the switch unit 19 can be reliably and satisfactorily turned on.
In this case, in the shock absorber 13, even if the elastic material 21 is rapidly elastically deformed after the head portion 16 of the operating member 12 receives a strong force such as an impact from the outside, the gel-like material 20 becomes hard as a solid and hardly deforms, and the shaft portion 15 of the operating member 12 can be pushed into the main body case 4 without being greatly pressed, so that even if the shaft portion 15 presses the contact plate 19b of the switch portion 19, the contact plate 19b is not pressed to the switch main body 19a, and the off state can be maintained without causing the switch portion 19 to perform an on operation.
In the switch device 3, the elastic member 21 includes the first outer wall portion 21b parallel to the sliding direction of the shaft portion 15 of the operation member 12 and the second outer wall portion 21c orthogonal to the sliding direction of the shaft portion 15, and the first outer wall portion 21b is formed to be thicker than the second outer wall portion 21c, so that when the elastic member 21 is pressed by the head portion 16 of the operation member 12, the first outer wall portion 21b can be reliably elastically deformed in the axial direction of the shaft portion 15, and thus elasticity can be ensured by the first outer wall portion 21 b.
In this case, the deformation amount of the first outer wall portion 21b when the cushion body 13 is pressed by the head portion 16 is larger than the deformation amount of the gel-like material 20 having the swelling property, whereby the elasticity of the elastic member 21 can be ensured. Therefore, the first outer wall portion 21b is elastically deformed by the head portion 16 of the operating member 12, and the gel-like material 20 is elastically deformed like a liquid, and at this time, the shaft portion 15 can reliably press the switch portion 19 to perform the on operation by the deformation amount of the first outer wall portion 21b and the deformation amount of the gel-like material 20.
In the switch device 3, by providing the gap R that allows deformation of the cushion body 13 between the inner peripheral surface of the housing recess 14 of the main body case 4 in which the cushion body 13 is disposed and the outer peripheral surface of the cushion body 13, when the cushion body 13 is pressed and compressed by the head portion 16 of the operating member 12, the cushion body 13 can be elastically deformed so as to expand in the radial direction orthogonal to the axial direction of the shaft portion 15, and thus the gel-like material 20 can exhibit expansion characteristics without compression of the volume of the gel-like material 20, and the elastic material 21 and the gel-like material 20 can be reliably and satisfactorily deformed.
Therefore, in the switch device 3, when the head portion 16 of the operating member 12 presses the cushion body 13 with a low impact, the elastic material 21 can be elastically deformed reliably, and the gel-like material 20 can be elastically deformed like a liquid, and when the head portion 16 of the operating member 12 presses the cushion body 13 with a high impact, the gel-like material 20 is hardly deformed even if the elastic material 21 is elastically deformed, and the gel-like material 20 can be hardened like a solid.
In the switch device 3, the plurality of elastic protrusions 23 are provided on the second outer wall portion 21c of the elastic member 21 so as to protrude in the sliding direction of the shaft portion 15 of the operating member 12, so that when the head portion 16 of the operating member 12 is pressed from the outside, the plurality of elastic protrusions 23 can be pressed against the bottom surface of the accommodating recess portion 14, and the plurality of elastic protrusions 23, the cylindrical portion 21a of the elastic member 21, and the first outer wall portion 21b can be elastically deformed satisfactorily, whereby the elasticity of the elastic member 21 can be secured, the operability of the operating member 12 can be improved, and the cushion body 13 in the accommodating recess portion 14 can be prevented from being loosened.
In the above-described embodiment, the case where the head portion 16 of the operating member 12 is longer than the cushion body 13 in the width direction has been described, but the present invention is not limited to this, and for example, the outer shape of the head portion 16 may be shorter than the cushion body 13 in the width direction, and a concave portion or a convex portion may be provided on the inner end surface of the head portion 16.
In this case, since the plate 22 disposed between the cushion body 13 and the head portion 16 is formed to have substantially the same size as the outer shape of the cushion body 13, even if the length of the head portion 16 in the width direction of the cushion body 13 is smaller and even if a concave portion or a convex portion is provided on the inner end surface of the head portion, the cushion body 13 can be uniformly pressed and deformed by the plate 22.
In the above-described embodiment, the case where the plate 22 is disposed between the cushion body 13 and the head portion 16 has been described, but the present invention is not limited to this, and for example, the plate 22 is not necessarily disposed if the outer shape of the head portion 16 of the operating member 12 is larger than the outer shape of the cushion body 13, that is, the length in the longitudinal direction, and the inner end surface of the head portion 16, which is the pressing region of the head portion 16, is formed as a flat surface.
In the above-described embodiment, the case where the plurality of elastic protrusions 23 are provided on the inner end surface of the second outer wall portion 21c of the elastic material 21 of the cushion body 13 facing the bottom surface of the storage recess 14 provided in the main body case 4 has been described, but the present invention is not limited to this, and for example, frame-shaped elastic protrusions may be provided on the end surface of the second outer wall portion 21c facing the inner end surface of the head 16, and the cylindrical portion 21a of the elastic material 21 may be protruded toward the head 16.
In the above-described embodiment, the case where the plurality of elastic protrusions 23 and the frame-shaped elastic protrusions are provided on the second outer wall portion 21c has been described, but the plurality of elastic protrusions 23 and the frame-shaped elastic protrusions are not necessarily provided in the present invention.
Further, in the above-described embodiment, the case where the present invention is applied to the switching device 3 located on the 2 o 'clock side of the wristwatch case 1 has been described, but the present invention is not limited to this, and can be applied to switching devices 3 other than the switching device 3 located on the 2 o' clock side.
In the above-described embodiments, the description has been made on the case of being applied to a wristwatch, but the present invention is not necessarily applied to a wristwatch, and can be applied to various watches such as a travel watch, an alarm clock, a desk clock, and a wall clock. The present invention is not necessarily a timepiece, and can be applied to electronic devices such as a mobile phone and a mobile terminal.
While the embodiment of the present invention has been described above, the present invention is not limited to the embodiment, and includes the embodiments described in the claims and the equivalent scope thereof.
