Description

  The present invention relates to a ring-type device that can adjust the inner diameter dimension of a cavity portion in which a human finger is mounted by making the protrusion amount of the inner diameter adjustment member variable, and in particular, in a state where the inner diameter adjustment member protrudes for some reason. The present invention relates to a ring-type device in which a finger can be easily removed even if adjustment cannot be performed.

  Conventionally, there are ring-type devices that are worn on human fingers, and such ring-type devices are used for various purposes. For example, a ring-type device may be used as a remote control device for remote control of various electric devices or game devices. In such an application as a remote control device, an operation unit that receives a user instruction, a transmission unit (for example, an infrared light emitting unit) for transmitting a control instruction wireless signal to the device body, and an electric power for generating a wireless signal. A ring-type device is provided with a substrate or the like. When the ring-type device is used as a remote control device for a game machine, various sensors (pressure sensor, acceleration sensor, etc.) for detecting the movement of the user's arm or hand are incorporated in the ring-type device. There are many cases.

  Moreover, it is mentioned that it is utilized for the detection apparatus of a biological signal as a use of a ring-type apparatus. The biological signal detection device is a device that detects a signal (biological signal) related to the pulse of the human body or the oxygen saturation concentration in the blood, and usually emits light toward a finger attached to the ring-type device. An element, a light receiving element that receives the light, and a detection processing unit (a substrate on which a detection IC or the like is mounted) that performs processing for deriving a value related to a pulse or oxygen saturation concentration according to the light receiving condition of the light receiving element, etc. It is provided in a ring type device. When detecting a biological signal, it is easier to detect the biological signal by applying an appropriate level of pressure to the detection target finger.

In Patent Document 1 and Patent Document 2 below, as an example of a ring-type device used for a biological signal detection device, the inner diameter dimension of a hollow portion (a portion where a finger is worn) of the ring-type device is adjusted. Various mechanisms for applying pressure to a worn finger have been disclosed. For example, Patent Document 1 discloses a mechanism that uses a rack-and-pinion gear transmission mechanism to adjust the amount of protrusion of a member that presses a finger (FIG. 28, etc.). Further, Patent Document 2 discloses a mechanism for applying pressure to a finger by sandwiching the finger by combining a semicircular member biased by a spring so as to be rotatable.

  In the ring-type device provided with the pressure application mechanism shown in Patent Document 1 and Patent Document 2 described above, adjustment can be performed in a state where pressure is applied to the finger due to a failure cause such as biting of a gear or catching of a rotating member. It is also assumed that there will be a situation of disappearance. When such a situation occurs, it is impossible to remove the finger by a normal method such as removing the ring, so that some kind of emergency removal mechanism is required. However, since the ring-type devices of Patent Document 1 and Patent Document 2 do not take effective measures against the above-described situation, there is a problem that it takes time and effort to remove a finger from the ring-type device. In FIG. 29 of Patent Document 1, an opening is formed by cutting out a part of the periphery of the part where the finger is to be worn, but the finger cannot be pulled out through this opening in terms of dimensions. Also, in FIG. 12 of Patent Document 2, an opening is provided at a place where the finger is to be worn. However, as in Patent Document 1, the finger cannot be removed dimensionally.

  The present invention has been made in view of such a problem, and an emergency take-out mechanism capable of generating an opening that secures a dimension that allows a finger to pass even when the finger cannot be removed due to a failure of a mechanism that adjusts the inner diameter. An object of the present invention is to provide a ring-type device provided with a ring.

  In order to solve the above-described problems, a ring-type device according to the present invention includes a ring-shaped housing and an inner diameter adjustment member that can project so as to adjust an inner diameter dimension of a hollow portion serving as a finger mounting portion of the ring-shaped housing.

The annular forming portion 28 forms a peripheral portion of the cavity portion 20a to which a finger is attached, and the end portion 28a protrudes to a position facing the slider 5 across the cavity portion 20a (see FIG. 3). Therefore, the subchassis 4 also extends to the end portion 28 a of the annular forming portion 28, whereby the rigidity of the protruding annular forming portion 28 is ensured, and the finger attached to the cavity portion 20 a is pressed by the slider 5. The load to be received is received.

  FIG. 6 shows the end face 28 b of the end portion 28 a of the annular forming portion 28. The end face 28b of the cavity 28 is open, and the chassis end 4a of the internal subchassis 4 is exposed. This chassis end portion 4a functions as an engaged portion to which the tip 25a of the separate housing portion 25 (corresponding to the other end in the peripheral direction of the hollow portion 20a) is engaged, and ensures the rigidity required for engagement. In order to do this, the cross section is bent so that it becomes a “U” shape of katakana. The chassis end 4a is formed with a positioning recess 4b when engaged with the separate housing part 25 at a substantially central portion in the width direction, and vertically long rectangular engagement holes on both sides of the recess 4b. 4c and 4d are formed.

  As shown in FIGS. 2 and 3, a hinge connecting portion 29 is provided in the vicinity of the portion where the slider 5 protrudes in the housing main body portion 20 b of the ring-shaped housing 20. The hinge connecting portion 29 is a location where one end 25b on the hinge rotation side of the separate housing portion 25 is connected, and the flexible circuit board 30 extending from the light receiving sensor 13 disposed in the separate housing portion 25 is hinged. It is drawn into the housing body 20b from the connecting portion 29 (see FIG. 3).

  As shown in FIG. 3, the first side cover 21 and the second side cover 22 are notched from the hinge connecting portion 29 to the end portion 28a of the annular forming portion 28 on the opposite side in the peripheral portion of the cavity portion 20a. Opening 31 is formed. The opening width L of the opening 31 is set to a dimension that allows a finger having a size defined as a mounting target of the cavity portion 20a to pass. In this embodiment, the opening width L is about 1/4 to the inner circumferential length of the cavity portion 20a. The dimension is set to about 1/3 (for example, 0.29 times the circumferential length).

  The opening 31 of the hollow portion 20a is made to appear by opening the separate housing portion 25 that is rotatably attached to the hinge connecting portion 29 of the housing main body portion 20b. The separate housing part 25 is generally “H” -shaped in hiragana, and the inner peripheral side of the cavity 20 a is formed by a box-shaped inner peripheral housing 35, and the outer surface side is covered by a plate-shaped outer surface cover 36. ing. The light receiving sensor 13 is housed in the inner peripheral housing 35 so that light emitted from the light emitting sensor 12 can be received through a hole formed in the inner peripheral housing 35 (see FIG. 3).

  FIG. 7A shows a state where the separate housing part 25 with the inner peripheral housing 35 removed is viewed from the inner peripheral surface side of the cavity 20a, and FIG. 7B shows the outer cover 36 removed. The upper body which looked at the housing separate body part 25 from the outer surface side is shown. In the separate housing part 25, the lock base angle 7, which is a metal plate-like member, is arranged on the inner surface side of the outer surface cover 36, and one end 7 a side of the lock base angle 7 is fixed to the inner surface of the outer surface cover 36. is doing.

  Further, the separate housing portion 25 has hinge support portions 7b and 7c erected on both sides in the width direction on one end portion 7a side of the lock base angle 7, and the hinge support portions 7b and 7c are provided with plate-like members. Angle 8 pins are fitted, and the angle 8 can be rotated with respect to the lock base angle 7 with these pins as the rotation center. The angle 8 is fixed to the inner surface of the side cover 23 through the hinge connecting portion 29 of the housing main body portion 20b (see FIGS. 4 and 5). As a result, the separate housing portion 25 is in the peripheral direction of the cavity portion 20a. The one end 25b is rotatable with respect to the housing main body 20b.

  Returning to FIG. 7A and FIG. 7B, the other end 7d of the lock base angle 7 (the other end in the peripheral direction of the cavity 20a) has a protruding portion 7e protruding from the tip. When the separate housing part 25 is in a closed state, the convex part 7e enters the concave part 4b of the subchassis 4 shown in FIG. 6 and positions the separate housing part 25 in the width direction. Further, a gap is provided between the other end 7d of the lock base angle 7 and the outer cover 36, and the lock angle 9 is disposed in this gap. The lock angle 9 is attached to the back surface of the lock base angle 7 so that it can slide in the direction of the arrow shown in FIG.

  As shown in FIG. 7 (a), the circuit board 13a on which the light receiving sensor 13 is mounted is disposed on the surface of the lock base angle 7. With this arrangement, the separate housing part 25 is provided. In the closed state, the mounting angle between the light receiving sensor 13 and the light emitting sensor 12 is an orthogonal positional relationship in the cavity 20 a, and the light emitted from the light emitting sensor 12 is easily received by the light receiving sensor 13.

  The lock angle 9 is urged so as to protrude outward by compression coil springs B1 and B2 (elastic bodies) positioned on both sides in the width direction attached to the lock base angle 7. Further, the lock angle 9 has a total of two engaging claws 9a and 9b (corresponding to the engaging portions) protruding from the front end on the engagement side of the separate housing part 25, and these engaging claws 9a and 9b. Is engaged with the engagement holes 4c and 4d of the sub-chassis 4 shown in FIG.

  That is, as shown in FIG. 8 (a), the engaging claws 9a and 9b are formed with oblique sides 9c and 9d at the tips, and when the separate housing part 25 is rotated from the opened state to the closing direction, As shown in FIG. 8B, the oblique sides 9 c and 9 d of the engagement claws 9 a and 9 b abut on the lower end side 4 e of the end 4 a of the subchassis 4. In this state, when the housing separate body portion 25 is further rotated in the closing direction, the oblique side portions 9c, 9d of the engaging claws 9a, 9b are pressed against the lower end side portion 4e of the sub-chassis 4 that comes into contact, and the compression is accordingly compressed. The lock angle 9 of the separate housing part 25 slides in the direction of the arrow in FIG. 8B against the urging force of the coil springs B1 and B2.

  Due to the sliding of the separate housing part 25 in the direction of arrow D, the protruding amount of the engaging claws 9a and 9b is reduced. The engaged claws 9 a and 9 b extend over the lower end side 4 e of the subchassis 4.

  As shown in FIG. 8C, when the engaging claws 9a and 9b reach the engaging holes 4c and 4d of the sub chassis 4 by further rotation of the separate housing part 25, the engaging claws 9a and 9b are Since the contact with the end 4a of the subchassis 4 is lost, the lock angle 9 slides in the direction of the arrow in FIG. 8C by the urging force of the compression coil springs B1 and B2. As a result, the engagement claws 9a and 9b enter the engagement holes 4c and 4d of the sub chassis 4, and the separate housing part 25 is closed and engaged with the annular forming part 28 of the housing main body part 20b.

  Further, as shown in FIG. 7B, an operation member 10 for releasing engagement is fixed to the back surface 9 e of the lock angle 9. The operation member 10 has an operation portion 10b provided with projections and depressions for preventing slipping from the surface 10a. The operation portion 10b of the operation member 10 is located inside the operation hole 36a of the outer surface cover 36 of the separate housing portion 25, but is outward from the outer peripheral surface 36b of the outer surface cover 36 as shown in FIG. It is formed at a height that does not protrude from the

  In order to release the engagement of the separate housing part 25 in the engaged state shown in FIG. 8C, the user operates the operation unit 10b so as to move it in the direction opposite to the arrow with the fingertip, and the operation member 10 is moved. It is performed by sliding in the direction opposite to the arrow together with the lock angle 9. Thus, by sliding the lock angle 9, the projecting engagement claws 9 a and 9 b are brought into a non-projecting state, and the engagement is released from the engagement holes 4 c and 4 d of the sub chassis 4. When the engagement is released, the housing separate body portion 25 can be rotated in the opening direction.

  Therefore, for example, even if the protruding slider 5 does not return to its original state due to the engagement of the gear that drives the slider 5, the user can operate the operation portion 10b of the operation member 10 as described above. For example, as shown in FIG. 3, the finger can be urgently removed by rotating so as to open the separate housing part 25 and attaching the finger to the cavity 20 a. Moreover, since the operation part 10b of the operation member 10 does not protrude from the outer surface 36b of the outer cover 36 of the separate housing part 25, a situation where the user touches carelessly to release the engaged separate housing part 25. Therefore, the user can detect the biological signal with peace of mind.

  The ring-type device 1 according to the present invention is not limited to the above-described embodiment, and various modifications can be applied. For example, the arrangement of the light emitting sensor 12 and the light receiving sensor 13 can be reversed from the above-described example, and an integrated sensor of a type in which the light emitting sensor 12 and the light receiving sensor 13 are integrated is used. May be. In this case, it is preferable that the integrated sensor is disposed at the position of the light emitting sensor 12 in the above-described example in that the wiring of the separate housing part 25 can be omitted. Of course, it is also possible to arrange them.

  Further, the housing separate body 25 is attached to the housing main body 20b in a manner opposite to the above-described example, by being rotatably attached to the end 28a of the annular forming portion 28, and the hinge connecting portion 29 of the above-described example. Can also be used as the engaging portion. Further, the separate housing portion 25 may be attached to the housing main body portion by engaging both ends, and may be completely removed from the housing main body portion in a state in which the engagement of both ends is released and opened. Thus, when the separate housing part 25 is detachable, there are no obstacles around the opening 31, and it is easier to remove the finger attached to the cavity 20a.

  Furthermore, the slider 5 is not driven by a motor, and a mechanism for manually projecting the slider 5 by rotating a dial-like member connected to a gear can be applied. Furthermore, in the above description, the ring-type device 1 has been described in the case of detecting a biological signal. However, the configuration according to the present invention is applied to a ring-type device for a remote controller for various electric device main bodies or game device main bodies. It is also possible. In this case, parts necessary for the remote controller are applied instead of the electrical parts related to the detection of the biological signal. As described above, when the configuration of the present invention is applied to a ring-type device for a remote controller, the finger can be easily pulled out even if the inner diameter dimension adjusting mechanism breaks down. A remote controller can be provided.
