Embodiments for Carrying Out the Invention

[0008] Hereinafter, embodiments of the present invention will be described. The holding device according to the embodiment of the present invention is a holding device in which a holding mechanism including a holding portion for holding an object to be held is supported by the device main body so as to be slidable in and out. This holding device is provided with a lock portion that is mounted on the holding mechanism and locks the holding mechanism at an arbitrary protruding position. And this lock portion includes the following first rotating body, second rotating body, and locking portion. The first rotating body is pivotally supported by the holding mechanism and rotates in response to an upright operation for raising the holding portion. The second rotating body rotates by receiving a force directly or indirectly from the first rotating body as the first rotating body rotates. Further, the locking portion moves between a locking position and a non-locking position where it locks to the device main body as the second rotating body rotates. Also, the lock portion locks the holding mechanism when the locking portion moves to the locking position, and releases the lock of the holding mechanism when the locking portion moves to the non-locking position. And the locking portion moves to the locking position by the upright operation.

[0009] According to the holding device according to this embodiment, since the mechanism for transmitting a predetermined operation to the locking portion in the locking portion is composed of a plurality of rotating elements such as the first rotating body and the second rotating body, for each rotating element, its length can be suppressed and the moving distance of the rotating end can be suppressed. The holding mechanism of the object to be held becomes thickest when the locking portion is mounted so that the rotation direction of the rotating element coincides with the thickness direction of the holding mechanism. According to the holding device according to this embodiment, since the moving distance of the rotating end of the rotating element is suppressed as described above, the thickness of the holding mechanism can also be suppressed, and as a result, the holding device can be miniaturized to suppress the occupied space at the installation location.

[0010] Here, in the holding device of this embodiment, the above-described locking portion further includes a biasing member that biases the locking portion toward the locking position. Thereby, during use when the object to be held is held by the holding mechanism, the locking portion is constantly biased and locked to the device main body, so that it can be used in a stable state.

[0011] Further, in the holding device of this embodiment, when the first rotating body moves the locking portion to the unlocking position against the biasing force of the biasing member, the first rotating body applies a force to the second rotating body by rotation to rotate it. On the other hand, when the locking portion moves to the locking position by the biasing force, the first rotating body rotates so as not to prevent the rotation of the second rotating body due to the biasing force received through the locking portion. Thereby, since the biasing force by the biasing member is used for the movement of the locking portion to the locking position, the transmission of the force to the locking portion by the first rotating body and the second rotating body only needs to consider moving the locking portion to the unlocking position. Thereby, the mechanism configuration regarding the force transmission can be simplified, so that the manufacturing and assembly costs and labor of the holding device can be reduced.

[0012] In addition, in the holding device of the present embodiment, a locked body with a plurality of locked portions arranged in the protruding and retracting direction of the holding mechanism is provided on the device main body, and the locking portion is configured to lock to the locked body. By using a locked body in which a plurality of locked portions are arranged linearly along the protruding and retracting direction, the storage space for the locking mechanism of the locking portion in the holding device can also be suppressed. Thereby, according to the holding device of the present embodiment, the holding device can be further miniaturized.

[0013] Further, the holding device of the present embodiment further includes a second locking portion provided on the device main body for locking the holding mechanism that has retracted to the storage position in the device main body. Thereby, the holding mechanism can be stably stored in the storage position.

[0014] In addition, in the holding device of the present embodiment, the holding mechanism includes a base portion that is supported by the device main body so as to be slidable in the protruding and retracting directions. The holding portion is pivotally supported by the base portion to hold the object to be held, and rotates with respect to the base portion by a laying-down operation and a standing-up operation of the holding portion. The locking portion moves to the locking position by the standing-up operation and moves to the non-locking position by the laying-down operation. Thereby, the rotation of the holding portion, which is an operation for the user to hold the object to be held, is utilized as an operation for locking and unlocking by the movement of the locking portion. For this reason, compared with the case where, for example, an operation button or the like is separately provided for locking and unlocking, the manufacturing cost can be reduced by suppressing the number of parts.

[0015] Further, the holding device of the present embodiment may be mounted on a vehicle, and the object to be held may be a portable device. Here, the portable device is an electronic device carried by a user, and examples include a smartphone, a tablet terminal, and a game device.

Example

[0016] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. The holding device of this embodiment is an in-vehicle device that is mounted and used on an instrument panel in the driver's seat of a vehicle. Further, the holding device of this embodiment holds, as an object to be held, a smartphone which is an example of a portable device.

[0017] FIG. 1 is a front view showing a holding device according to an embodiment of the present invention, FIG. 2 is a perspective view showing a state in which a smartphone is held by the holding device shown in FIG. 1, and FIG. 3 is an exploded perspective view of the holding device shown in FIG. 1.

[0018] The holding device 1 of this embodiment includes a holding mechanism 10 for a smartphone 5 and a rectangular box-shaped device body 20 mounted on the instrument panel.

[0019] The holding mechanism 10 is detachably held by the device body 20. Further, the holding mechanism 10 includes a base portion 11 that is supported by the device body 20 so as to be slidable in and out, and a holding portion 12 that is pivotally supported by this base portion 11 and holds the smartphone 5. When holding the smartphone 5, the holding mechanism 10 has the base portion 11 pulled out from the device body 20 in the protruding direction D111 in the in-and-out direction D11 shown in FIG. 3, and the holding portion 12 is erected in the standing direction D121 in the rotation direction D12 shown in FIG. 2. And it is configured to hold the smartphone 5 on this erected holding portion 12.

[0020] The device body 20 includes an upper chassis 21 formed by an upper wall and a pair of side walls in the rectangular box-shaped device body 20, and a lower chassis 22 forming a lower wall. The base 11 of the above-described holding mechanism 10 is supported on the upper wall of the upper chassis 21 so as to be slidable in and out. On the lower chassis 22, a rectangular back substrate 221 forming the back wall of the device body 20 is erected at one end on the back side in the rectangular box-shaped device body 20. Mounted on this back substrate 221 are various connectors for connection to external devices and an antenna or the like for performing short-distance communication conforming to, for example, the Bluetooth (registered trademark) standard or the like with the smartphone 5. Also, an inner surface substrate 222 electrically connected to the back substrate 221 is attached to the inner surface of the lower chassis 22.

[0021] Further, the device body 20 includes a rectangular plate-shaped detachable front panel portion 23 forming the front wall of the device body 20 and serving as a user interface, and a panel portion 24 that detachably and rotatably holds the front panel portion 23. The panel portion 24 is fixed to the upper chassis 21 and the lower chassis 22. The panel portion 24 is formed in a shape with a notch so as not to interfere with the holding mechanism 10 supported by the upper chassis 21. A pair of shaft protrusions 231 serving as rotation shafts are provided at both ends in the longitudinal direction of the front panel portion 23, and these pair of shaft protrusions 231 are detachably and rotatably held by a pair of holding arms 241 in the panel portion 24.

[0022] In the holding device 1 of this embodiment, each of the holding mechanism 10 supported by the upper chassis 21 and the panel portion 24 is electrically connected to the inner surface substrate 222 of the lower chassis 22 by a cable 223. In this embodiment, as shown in FIG. 2, touch operations on the held smartphone 5 or button operations on the front panel portion 23 can be used to, for example, display map information on the screen of the smartphone 5 or play music from the in-vehicle audio device. Also, charging of the held smartphone 5 can be performed via a cable 223 connecting the holding mechanism 10 and the inner surface substrate 222 and a charging cable extending from the smartphone 5 and connected to the holding mechanism 10.

[0023] The smartphone 5 is held by the holding device 1 described above according to the following procedure.

[0024] FIG. 4 is a schematic diagram showing an example of a procedure for holding a smartphone by the holding device shown in FIGS. 1 to 3. In FIG. 4, for ease of viewing, only the upper chassis 21 of the device body 20 is shown. The procedures described below are performed manually by the user.

[0025] First, in steps S11 and S12, the holding mechanism 10 is pulled out from the device body 20 in the protruding direction D111. At this time, in this embodiment, the front panel portion 23 is rotated forward about the shaft protrusion 231 shown in FIG. 3 or removed from the panel portion 24 so as not to interfere with the movement of the holding mechanism 10.

[0026] In the subsequent step S13, in the holding mechanism 10, the holding portion 12 is erected in the upright direction D121 with respect to the base portion 11. At this time, the holding portion 12 includes a chucking portion 121 having three holding claws 122. In this embodiment, in the state where the holding portion 12 is erected in step S13, the chucking portion 121 has a posture in which one holding claw 122 is located on the upper side and two holding claws 122 are located on the lower side. Further, in the chucking portion 121, one holding claw 122 on the upper side is spring-biased toward the two holding claws 122 on the lower side.

[0027] In step S14, the upper holding claw 122 in the chucking portion 121 is pulled upward in the pulling-up direction D131 against the spring bias.

[0028] Then, in step S15, the smartphone 5 is placed between the upper holding claws 122 and the lower holding claws 122 that are pulled up as described above, in a horizontal placement state where its longitudinal direction faces the horizontal direction. When the user releases the upper holding claw 122, the upper holding claw 122 moves in the downward direction D132 due to the above-described spring biasing. As a result, the smartphone 5 is clamped between the upper holding claw 122 and the lower holding claw 122.

[0029] Here, in the present embodiment, in the holding portion 12, the chucking portion 121 is rotatably attached about the rotation axis 121a in the rotation direction D14. At the stage of step S15 as described above, the smartphone 5 is held in a horizontal placement state. When the user wants to view the display surface with the smartphone 5 in a vertical placement state where its longitudinal direction faces the vertical direction, the smartphone 5 can be set to the vertical placement state by the following step S16. That is, in step S16, the chucking portion 121 together with the smartphone 5 is rotated 90° in the clockwise rotation direction D141 in the figure about the rotation axis 121a. By this rotation, the smartphone 5 becomes in the vertical placement state. Further, after this, when the user wants to view the display surface with the smartphone 5 in the horizontal placement state, the chucking portion 121 is rotated back 90° counterclockwise in the figure, and the smartphone 5 becomes in the horizontal placement state. Note that the rotation direction of the chucking portion 121 may be set opposite to that of the present embodiment.

[0030] Also, in the present embodiment, the user returns the front panel portion 23 at an arbitrary timing after pulling out the holding mechanism 10. As a result, the appearance after holding the smartphone 5 becomes an appearance as shown in, for example, FIG. 2.

[0031] When the smartphone 5 is removed and the holding mechanism 10 is stored in the apparatus main body 20, the holding mechanism 10 is stored by a procedure reverse to the procedure shown in FIG. 4.

[0032] Next, a structure for supporting the holding mechanism 10 to be slidably projected in and out of the apparatus main body 20 will be described.

[0033] FIG. 5 is a perspective view showing a structure in which a holding mechanism is supported by a device main body so as to be slidable in and out. In this FIG. 5, the above structure is shown from the back side of the holding device 1 using the upper chassis 21 that supports the holding mechanism 10. Further, FIG. 6 is a perspective view of the structure shown in FIG. 5 with the upper chassis removed.

[0034] The upper chassis 21 of the device main body 20 is a sheet metal processed part, and together with the lower chassis 22 (see FIG. 3), which is also a sheet metal processed part, constitutes a metal housing 20a in the device main body 20. A pair of slide support portions 212 for slidably supporting the holding mechanism 10 in and out are provided on the inner surface of the upper surface portion 211 of the upper chassis 21. The slide support portions 212 are resin molded parts. Each slide support portion 212 is provided with a support groove 212a extending in the in-and-out direction D11, and both end portions 111 in the left-right direction D15 intersecting the in-and-out direction D11 at the base portion 11 of the holding mechanism 10 are respectively fitted into the support grooves 212a. Thereby, the holding mechanism 10 is supported so as to be slidable in and out.

[0035] Also, a guide groove 211a extending in the in-and-out direction D11 of the holding mechanism 10 is provided on the upper surface portion 211 of the upper chassis 21 so as to penetrate in a slit shape. And a protrusion member 112 having two protrusions 112a arranged in the in-and-out direction D11, which protrudes from the holding mechanism 10 and is inserted into the guide groove 211a, is provided at the base portion 11 of the holding mechanism 10. This protrusion member 112 is formed by erecting two metal round bar-shaped protrusions 112a on a rectangular sheet metal 112b.

[0036] Here, in the present embodiment, the support of the holding mechanism 10 by the pair of slide support portions 212 allows a certain amount of play in the left-right direction D15. And the holding mechanism 10 is configured to be slid in and out in the in-and-out direction D11 with the play in the left-right direction D15 regulated by the guide groove 211a and the protrusion member 112.

[0037] Furthermore, the protruding member provided at the base 11 is not limited to the protruding member 112 having two protrusions 112a as in this embodiment. FIG. 6 also shows an alternative protruding member 512 in place of the protruding member 112 of this embodiment. This alternative protruding member 512 has a rib-shaped metal protrusion 512a formed to be long in the protruding and retracting direction D11, standing on a rectangular sheet metal 512b.

[0038] Also, in this embodiment, the guide groove 211a on the upper surface portion 211 of the upper chassis 21 is provided at a position near the central region 211b in the left-right direction D15. This is because the central region 211b in the left-right direction D15 on the upper surface portion 211 is utilized as a holding region by the fixing structure on the instrument panel side when the holding device 1 is mounted on the instrument panel. The guide groove 211a is provided as close to the center as possible while avoiding the central region 211b as this holding region. By providing the guide groove 211a closer to the center, the protruding member 112, that is, the holding mechanism 10, can be guided in the protruding and retracting direction D11 with good balance in the left-right direction D15.

[0039] The guide groove for the protruding member described above is not limited to the guide groove 211a provided at a position near the central region 211b in the left-right direction D15 as in this embodiment. For example, if there is no position restriction due to the fixing structure on the instrument panel side or the like, the guide groove 211a may be provided in the central region 211b in the left-right direction D15 and configured to guide with a better balance.

[0040] Furthermore, in this embodiment, a protruding lock portion 13 (locking portion) for locking the holding mechanism 10 at an arbitrary protruding position and a storage lock portion 14 (second locking portion) for locking the holding mechanism 10 at the storage position are mounted on the holding mechanism 10.

[0041] FIG. 7 is a perspective view showing the protruding lock portion and the storage lock portion shown in FIG. 5 as viewed from above in the direction of arrow V11 in FIG. 5.

[0042] The protruding locking portion 13 and the storage locking portion 14 are provided on the back side of one of the both end portions 111 in the left-right direction D15 intersecting the protruding and retracting direction D11 at the base portion 11 of the holding mechanism 10. Further, a locking projection 213 for locking the storage locking portion 14 is provided on the upper chassis 21 of the apparatus main body 20. Furthermore, among the pair of slide support portions 212, on the slide support portion 212 on the side corresponding to the protruding locking portion 13, a resin rack 212b with saw teeth 212b-1 arranged in the protruding and retracting direction D11 is provided, which the protruding locking portion 13 locks to.

[0043] First, the storage locking portion 14 and the locking projection 213 will be described.

[0044] FIG. 8 is a schematic diagram showing a state where the storage locking portion shown in FIG. 7 is locked to the locking projection provided on the upper chassis.

[0045] The storage locking portion 14 includes a lock lever 141 and a torsion spring 142 for storage locking. The lock lever 141 is a bent bar-shaped member provided with a locking hook 141a at the tip on the back side of the holding device 1, and is pivotally supported by a storage locking rotation shaft 113 provided on the base portion 11 in the vicinity of the bent portion. The torsion spring 142 for storage locking biases the lock lever 141 in the storage locking biasing direction D161 in which the locking hook 141a faces the upper chassis 21 around the storage locking rotation shaft 113. Further, the locking hook 141a is provided with slopes on the front side and the rear side in the retracting direction D112 in the protruding and retracting direction D11, respectively.

[0046] The locking projection 213 provided on the upper chassis 21 is provided with slopes corresponding to the above slopes on the locking hook 141a on the front side and the rear side in the retracting direction D112, respectively.

[0047] When the holding mechanism 10 is pushed into the apparatus main body 20 in the immersion direction D112, first, in step S21 of FIG. 8, the front slope of the locking hook 141a contacts the rear slope of the locking projection 213. In the next step S22, the holding mechanism 10 is further pushed in the immersion direction D112. Then, the front slope of the locking hook 141a is pushed up so as to rub against the rear slope of the locking projection 213, and the lock lever 141 rotates in the overriding rotation direction D162 opposite to the storage lock biasing direction D161 against the biasing force of the storage lock torsion spring 142. As a result, the locking hook 141a overrides the locking projection 213.

[0048] In the subsequent step S23, the holding mechanism 10 is further pushed in the immersion direction D112, the locking hook 141a overrides the locking projection 213, and the lock lever 141 rotates in the storage lock biasing direction D161 by the biasing force of the storage lock torsion spring 142. As a result, the locking hook 141a locks onto the locking projection 213 to enter the locked state and reach the storage position.

[0049] When the holding mechanism 10 is pulled out from the apparatus main body 20 in the protruding direction D111, as the holding mechanism 10 advances in the protruding direction D111, the locking hook 141a rotates in the overriding rotation direction D162 against the biasing force of the storage lock torsion spring 142. Thereby, the locking hook 141a overrides the locking projection 213 and the lock is released.

[0050] Next, the structure of the holding mechanism 10 including the base 11 and the holding portion 12 will be described in more detail.

[0051] As described with reference to FIG. 4, the holding mechanism 10 is pulled out from the apparatus main body 20 in a state where the holding portion 12 extends on the extension of the base portion 11 and has a single-plate shape. Also, even when being stored in the apparatus main body 20, the holding mechanism 10 has such a single-plate shape. Then, after the holding mechanism 10 is pulled out from the apparatus main body 20, the holding portion 12 is erected in the erecting direction D121, and the smartphone 5 is held by the holding portion 12. To enable such movement, the holding portion 12 is hinge-coupled to one end of the base portion 11.

[0052] FIG. 9 is a diagram showing the coupling structure between the base portion and the holding portion in the holding mechanism.

[0053] This FIG. 9 shows a state in which the holding mechanism 10 is pulled out from the apparatus main body 20 in the protruding direction D111 with only the upper chassis 21 of the holding device 1 shown, and the holding portion 12 is erected. Further, an enlarged view of the coupling structure between the base portion 11 and the holding portion 12 in that state, as viewed from the bottom surface side of the base portion 11, and an enlarged view of one of the pair of left and right provided coupling structures, are shown.

[0054] In this coupling structure, a base side sheet metal frame 114 that constitutes the bottom surface side of the base portion 11 and a holding side sheet metal frame 123 that constitutes the back surface side of the holding portion 12, which is the side opposite to the side where the smartphone 5 is held, are hinge-coupled. In each of the left and right coupling structures, a torque hinge 15 is provided so as to sandwich a part of the base side sheet metal frame 114 and a part of the holding side sheet metal frame 123. By this torque hinge 15, the erected state of the holding portion 12 when erected as described above is maintained while withstanding the weight even when holding the smartphone 5.

[0055] Next, the protruding lock portion 13 and the rack 212b shown in FIG. 7 will be described.

[0056] In this embodiment, when the base portion 11 and the holding portion 12 in the holding mechanism 10 are in a single-plate shape, the protruding locking portion 13 is in an unlocked state with respect to the rack 212b, and the holding mechanism 10 is slidable in the protruding and retracting direction D11. Then, when the holding portion 12 is erected at an arbitrary protruding position, the protruding locking portion 13 becomes locked with respect to the rack 212b.

[0057] FIG. 10 is a view showing the holding mechanism in the storage position from a direction in which the rack and the protruding locking portion can be seen. In FIG. 10, the upper chassis 21 of the apparatus main body 20 and the holding mechanism 10 are shown upside down compared to FIG. 7. Further, FIG. 11 is a view showing a state in which the holding mechanism shown in FIG. 10 is pulled out from the apparatus main body to an arbitrary protruding position while remaining in a single-plate shape. Furthermore, FIG. 12 is a view showing a state in which the holding portion is erected in the holding mechanism at an arbitrary protruding position shown in FIG. 11.

[0058] In the states of FIGS. 10 and 11, in the single-plate-shaped holding mechanism 10, the locking portion 131 provided in the protruding locking portion 13 is in a state of being rotated upward in the non-locking direction D17 away from the upper chassis 21, as will be described in detail later. For this reason, the holding mechanism 10 is slidable in the protruding and retracting direction D11 without interference between the rack 212b provided on the slide support portion 212 and the locking portion 131.

[0059] On the other hand, in the state of FIG. 12, in the holding mechanism 10 at an arbitrary protruding position, the holding portion 12 is erected with respect to the base portion 11, and the locking portion 131 is in a state of being rotated downward in the locking direction D18 approaching the upper chassis 21. As a result, the locking portion 131 locks to the rack 212b, and the holding mechanism 10 is locked at the protruding position. The locking portion 131 locks to the saw teeth 212b-1 at an arbitrary position among the saw teeth 212b-1 arranged in a row on the rack 212b. In this way, the rack 212b serves as a locked body in which a plurality of saw teeth 212b-1 as locked portions are arranged in the protruding and retracting direction D11.

[0060] In this embodiment, the rotation of the locking portion 131 for locking by the protruding lock portion 13 is performed in response to a rotation operation in which the user rotates the holding portion 12 so as to stand it up with respect to the base portion 11.

[0061] FIG. 13 is a view showing the protruding lock portion so that the entire structure including the structure for rotating the locking portion can be seen, excluding the base side plate metal frame constituting the bottom surface side of the base, from the holding mechanism shown in FIG. 12. FIG. 14 is a view showing an enlarged view of the protruding lock portion shown in FIG. 13, and arranging the state where the locking portion is in the unlocked position and the state where the locking portion is in the locked position with respect to the rack. In FIG. 14, the state where the locking portion is in the unlocked position is shown on the upper side in the figure, and the state where the locking portion is in the locked position is shown on the lower side in the figure.

[0062] In this embodiment, the protruding lock portion 13 includes a locking portion 131, a first rotating body 132, a second rotating body 133, a backlash suppressing torsion spring 134, and a protruding lock torsion spring 135.

[0063] The first rotating body 132 is pivotally supported by a first protruding lock rotation shaft 115 provided on the base portion 11 of the holding mechanism 10. The backlash suppressing torsion spring 134 biases the first rotating body 132 in the backlash suppressing biasing direction D19, which is a direction of pressing the end portion on the second rotating body 133 side toward the second rotating body 133 around the first protruding lock rotation shaft 115, to suppress the backlash of the first rotating body 132. The second rotating body 133 is pivotally supported by a second protruding lock rotation shaft 116 provided on the base portion 11 of the holding mechanism 10. The protruding lock torsion spring 135 biases the second rotating body 133 together with the locking portion 131 in the protruding lock biasing direction D20 in which the locking portion 131 moves toward the locking position around the second protruding lock rotation shaft 116. The protruding lock biasing direction D20 is the same direction as the locking direction D18 shown in FIG. 12. The first rotating body 132 and the second rotating body 133 are arranged with their end portions in contact with each other.

[0064] The locking part 131 is a rectangular resin plate, and a protrusion 131a is provided at the edge in the biasing direction D20 for protruding lock. Such a locking part 131 is fixed to the end of the second moving body 133 on the side opposite to the first moving body 132. When locking to the rack 212b, this locking part 131 moves to the locking position shown on the lower side of FIG. 14 by the rotation of the second moving body 133 receiving the biasing force of the torsion spring 135 for protruding lock. And at this locking position, the protrusion 131a of the locking part 131 locks to the serration 212b-1 of the rack 212b. On the contrary, when the locking to the rack 212b is released, it moves to the non-locking position shown on the upper side of FIG. 14 by the reverse rotation of the second moving body 133 against the biasing force of the torsion spring 135 for protruding lock. In the non-locking position, the protrusion 131a of the locking part 131 separates from the serration 212b-1 of the rack 212b.

[0065] And in this embodiment, in the holding mechanism 10, the first moving body 132 and the second moving body 133 rotate along with the rotation operation by which the user rotates the holding part 12 with respect to the base part 11, so as to move the locking part 131.

[0066] FIG. 15 is a schematic diagram showing a state where the locking part is moved by the rotation of the first moving body and the second moving body along with the rotation operation with respect to the holding part. In this FIG. 15, only the holding part 12, the protruding locking part 13, and the rack 212b are shown for easy viewing of the figure. Above the figure in FIG. 15, the state where the locking part 131 is in the non-locking position is shown, and below the figure, the state where the locking part 131 is in the locking position is shown.

[0067] When the holding part 12 is rotated in the standing direction D121 which is also shown in FIG. 2, with this rotation operation, the first rotating body 132 rotates in the direction of arrow D23. The rotation of this first rotating body 132 is a movement in which the end part is pressed in the direction of arrow D23 by the rotation of the second rotating body 133 due to the biasing force in the protruding locking biasing direction D20 by the protruding locking torsion spring 135 received via the locking part 131. The second rotating body 133 rotates to the locking position with respect to the rack 212b in the locking direction D18 by this biasing force. At this locking position, as described above, the protrusion 131a of the locking part 131 locks to the serration 212b-1 of the rack 212b. Thereby, the holding mechanism 10 is locked. In this embodiment, the protruding locking torsion spring 135 serves as a biasing means for biasing the locking part 131 for locking. During such a movement, the first rotating body 132 continues to have its end part pressed against the second rotating body 133 by the biasing force in the backlash suppressing biasing direction D19 by the backlash suppressing torsion spring 134, and the backlash is suppressed.

[0068] On the other hand, when the holding part 12 is rotated in the lying direction D122 opposite to the standing direction D121, with this rotation operation, the first rotating body 132 rotates in the direction of arrow D21 against the pressing of the second rotating body 133 which has received the biasing force of the protruding locking torsion spring 135. The rotation of this first rotating body 132 is a movement of pushing down the end part on the side of the first rotating body 132 in the second rotating body 133 against the biasing force in the protruding locking biasing direction D20. As a result, the second rotating body 133 rotates to the unlocking position with respect to the rack 212b in the unlocking direction D22 against the biasing force in the protruding locking biasing direction D20. At this unlocking position, as described above, the protrusion 131a of the locking part 131 separates from the serration 212b-1 of the rack 212b. Thereby, the locking of the holding mechanism 10 is released. In this embodiment, the first rotating body 132 and the second rotating body 133 serve as releasing means for releasing the lock. Also during this time, the first rotating body 132 continues to have its end part pressed against the second rotating body 133 by the biasing force in the backlash suppressing biasing direction D19, and the backlash is suppressed.

[0069] Here, in this embodiment, in order to rotate the first rotating body 132 along with the rotation operation of the holding part 12, the following structure is adopted.

[0070] FIG. 16 is a cross-sectional view of the holding mechanism showing the structure for rotating the first rotating body along with the rotation operation of the holding part. In this FIG. 16, the state in which the holding part 12 is rotated in the laying direction D122 shown in FIG. 15 and the lock is released is shown at the uppermost stage in the figure, and the state in which the holding part 12 is rotated in the upright direction D121 and locked is shown at the lowermost stage in the figure. And in the middle stage in the figure, the state in which the holding part 12 is in the middle of rotation and in the middle of transition between the locked state and the unlocked state is shown.

[0071] Further, FIG. 17 is a perspective view of the boundary part between the holding part in the unlocked state shown in FIG. 16 and the protruding lock part, as viewed in the direction of arrow V12 in FIG. 16. Further, FIG. 18 is a perspective view of the boundary part between the holding part in the locked state shown in FIG. 16 and the protruding lock part, as viewed in the direction of arrow V13 in FIG. 16.

[0072] In this embodiment, the first rotating body 132 in the protruding lock part 13 is provided on the base 11 and serves as an operating arm for switching between the locked state and the unlocked state of the base. And the holding part 12 is provided with a switching part 123a for moving the first rotating body 132 as an operating arm along with the rotation of the holding part 12, so as to cause the first rotating body 132 to perform the above switching. This switching part 123a is formed by extending a part of the holding side plate metal frame 123, which is the chassis constituting the holding part 12 and is also shown in FIG. 9. The switching part 123a is formed by bending a part of this holding side plate metal frame 123 so as to protrude toward the inside of the holding part 12. And the first rotating body 132 is moved at the tip of the bent shape.

[0073] The holding part 12 has one end 12a pivotally supported on the base part 11 via a rotation axis 151 passing through the center of the torque hinge 15. And the tip part 132a of the first rotating body 132 extends beyond this rotation axis 151 toward the side of the holding part 12. The switching part 123a is provided on the side of the other end 12b (see FIG. 9) of the holding part 12, which is opposite to the one end 12a, rather than on the side of the above rotation axis 151. This switching part 123a moves the tip part 132a of the first rotating body 132 as the holding part 12 rotates.

[0074] Also, an inclined surface 132b is provided at the tip part 132a of the first rotating body 132, which intersects the extending direction D24 of the first rotating body 132 and faces the immersion side in the protruding / immersion direction D11 of the base part 11. A concave part 132c is provided on the immersion side of the first rotating body 132 rather than the inclined surface 132b. Further, an intersecting surface 132d is provided at the tip part 132a of the first rotating body 132, which extends from the above inclined surface 132b so as to intersect the inclined surface 132b toward the protruding side in the protruding / immersion direction D11.

[0075] As shown in the upper part of FIG. 16 and FIG. 17, when the holding part 12 is laid on the base part 11 so as to be in a single - plate shape, the switching part 123a presses the intersecting surface 132d with the tip of its bent shape. In this state, the first rotating body 132 rotates in the direction of arrow D21 by the pressing of the switching part 123a, and together with the second rotating body 133, the locking part 131 rotates to the unlocking position with respect to the rack 212b in the unlocking direction D22 against the biasing force of the protruding - locking torsion spring 135. That is, in this state, the base part 11 is set to the unlocking state.

[0076] When the holding part 12 rotates about the rotation axis 151 in the upright direction D121, as shown in the middle row of FIG. 16, the pressing position by the switching part 123a moves from the intersection surface 132d to the inclined surface 132b. Then, when the holding part 12 further rotates in the upright direction D121, as shown in the bottom row of FIG. 16 and FIG. 18, the switching part 123a separates from the immersion side in the protruding / retracting direction D11 from the inclined surface 132b to release the pressing against the inclined surface 132b, and its tip end fits into the recess 132c. Also, at this time, the tip end of the bent shape in the switching part 123a faces the protruding side in the protruding / retracting direction D11. Since the pressing is released, the first rotating body 132 is pressed at its end by the second rotating body 133 by the biasing force of the protruding locking torsion spring 135 and rotates in the direction of arrow D23. As described with reference to FIG. 15, due to the rotation of the first rotating body 132 in the direction of arrow D23, the locking part 131 rotates together with the second rotating body 133 to the locking position with respect to the rack 212b in the locking direction D18. That is, in this state, the base 11 is set in the locked state.

[0077] When the holding part 12 rotates in the reverse direction from the upright state, as shown in the middle row of FIG. 16, the tip end of the switching part 123a comes out of the recess 132c and presses the inclined surface 132b. Also, as the holding part 12 rotates, the pressing position by the switching part 123a moves from the inclined surface 132b to the intersection surface 132d. Due to this pressing by the switching part 123a, the first rotating body 132 rotates in the direction of arrow D21, and the base 11 shifts to the unlocked state.

[0078] With the structure described above, as the holding part 12 rotates, the first rotating body 132 rotates, and along with this rotation, the locking part 131 rotates together with the second rotating body 133, and the switching between the unlocked state and the locked state, and the switching from the locked state to the unlocked state are performed.

[0079] FIG. 19 is a diagram showing, in a simplified manner using a schematic diagram, the switching operation between the locked state and the unlocked state described with reference to FIGS. 14 to 18. The unlocked state is shown on the upper side of FIG. 19, and the locked state is shown on the lower side.

[0080] First, in the unlocked state of the protruding lock portion 13, the tip 132a of the first rotating body 132 is pressed by the switching portion 123a (see FIGS. 16, 17, and 18) in the holding portion 12 laid in the laying direction D122 (see FIG. 15). By this pressing, the first rotating body 132 rotates in the direction of arrow D21 against the pressing of the second rotating body 133 receiving the biasing force of the torsion spring 135 for protruding lock. As a result, the locking portion 131 together with the second rotating body 133 rotates to the unlocked position away from the rack 212b in the unlocking direction D22 against the biasing force of the torsion spring 135 for protruding lock. During this time, due to the biasing force of the torsion spring 134 for backlash suppression, the end portion of the first rotating body 132 is continuously pressed against the second rotating body 133, and backlash is suppressed.

[0081] On the other hand, in the locked state of the protruding lock portion 13, the switching portion 123a in the holding portion 12 erected in the erecting direction D121 (see FIG. 15) is separated from the tip 132a of the first rotating body 132. By this separation, the locking portion 131 together with the second rotating body 133 rotates to the locking position locking to the rack 212b in the locking direction D18 by the biasing force of the torsion spring 135 for protruding lock. Also during this time, due to the biasing force of the torsion spring 134 for backlash suppression, the end portion of the first rotating body 132 is continuously pressed against the second rotating body 133, and backlash is suppressed.

[0082] Here, in this embodiment, in the locked state (locking state) where the locking portion 131 is locked to the rack 212b, the holding mechanism 10 can move in the protruding / retracting direction D11 together with the protruding lock portion 13. At this time, the holding mechanism 10 moves while receiving a resistance force due to the interference between the locking portion 131 and the rack 212b.

[0083] FIG. 20 is a schematic diagram showing a state where the holding mechanism moves while receiving a resistance force due to the interference between the locking portion and the rack in the locked state.

[0084] First, in the protruding direction D111 of the protruding and retracting direction D11, the holding mechanism 10 moves while receiving a first resistance force F11 in the direction opposite to the protruding direction D111. Also, in the retracting direction D112, the holding mechanism 10 moves while receiving a second resistance force F12 in the direction opposite to the retracting direction D112. In the movement in any direction, the locking portion 131 rotates against the biasing force of the protruding lock torsion spring 135 while the protrusion 131a slides against the serrations 212b-1 of the rack 212b and climbs over the serrations 212b-1. The first resistance force F11 and the second resistance force F12 received by the holding mechanism 10 are associated with such climbing over in the locking portion 131.

[0085] With such a configuration, even when an impact is unintentionally applied to the holding mechanism 10, such as when the user's hand hits it, after the holding mechanism 10 is pulled out to the protruding position and enters the locked state, the movement of the holding mechanism 10 can absorb and reduce the impact.

[0086] At this time, in this embodiment, the first resistance force F11 and the second resistance force F12 are set to be substantially the same as each other. Since the first resistance force F11 and the second resistance force F12, which are opposite to each other in the protruding and retracting direction D11, are set to be substantially the same, the impact can be absorbed and reduced in the same way regardless of the direction in which the impact is applied.

[0087] Note that the magnitude relationship between the first resistance force and the second resistance force is not limited to being substantially the same as in this embodiment, and they may be made different from each other. FIG. 20 also shows another example in which the first resistance force and the second resistance force are set to different magnitudes. In this other example, the second resistance force F52 is set to be larger than the first resistance force F51. Thereby, for example, it is possible to adopt a configuration that takes into account the operability of the smartphone 5, such as configuring so that when the user touches and operates the display screen of the smartphone 5, it does not retract as much as possible from the locked state position. By adopting the above configuration, furthermore, even after the holding portion 12 is raised, fine adjustment of the locked position is possible in the protruding direction, improving the convenience for the user.

[0088] Here, in this embodiment, the first resistance force F11 and the second resistance force F12 are first set based on setting conditions including the inclination angle θ11 on the protruding side in the protruding and retracting direction D11 and the inclination angle θ12 on the retracting side in the sawtooth 212b-1 of the rack 212b. Further, an inclined surface 131a-1 is formed at the tip of the protrusion 131a of the locking portion 131 on the retracting side in the protruding and retracting direction D11. The inclination angle θ13 of this inclined surface 131a-1 is used for the setting condition of the second resistance force F12.

[0089] Also, the locking portion 131 moves along a rotation path 131b centered on the second rotation shaft 116 for protruding lock with respect to the rack 212b. And the rack 212b moves and locks at a predetermined entering angle θ14. In this embodiment, the entering angle θ14 of the locking portion 131 with respect to the rack 212b is also used as a setting condition for setting the first resistance force F11 and the second resistance force F12. In addition to this, the biasing force of the torsion spring 135 for protruding lock, etc. is also used for the setting conditions of the first resistance force F11 and the second resistance force F12.

[0090] According to the holding device 1 of this embodiment described above, in the protruding lock portion 13, the mechanism for transmitting the rotation operation with respect to the holding portion 12 to the locking portion 131 is composed of a plurality of rotating elements such as the first rotating body 132 and the second rotating body 133. Therefore, for each rotating element, its length can be suppressed and the moving distance of the rotating end can be suppressed.

[0091] Here, in this embodiment, the protruding lock portion 13 is mounted on the holding mechanism 10 so that the rotation directions of the first rotating body 132 and the second rotating body 133 coincide with the thickness direction of the holding mechanism 10. Therefore, the holding mechanism 10 is formed to have a thickness sufficient to accommodate the moving distance of this rotating end.

[0092] FIG. 21 is a diagram showing a comparative example for comparison with the holding device shown in FIGS. 1 to 20. In this FIG. 21, the protruding lock portion 63 in the unlocked state of the holding mechanism 60 of the holding device 6 of the comparative example is shown on the upper side in the figure, and the protruding lock portion 63 in the locked state is shown on the lower side in the figure. The protruding lock portion 63 of this comparative example has a single rotating body 631 pivotally supported by a protruding lock pivot shaft 616 provided on the base portion 61. For this reason, the moving distance A61 of the rotating end of the rotating body 631 extending long from the protruding lock pivot shaft 616 becomes large, and the base portion 61 (that is, the holding mechanism 60) requires a sufficient thickness to accommodate this large moving distance A61 of the rotating end.

[0093] In contrast to this comparative example, according to the holding device 1 according to the present embodiment, as described above, the moving distances of the rotating ends of the first rotating body 132 and the second rotating body 133 as the rotating elements can be suppressed. Thereby, the thickness of the base portion 11 in particular in the holding mechanism 10 can also be suppressed, and as a result, the holding device 1 can be miniaturized in order to suppress the occupied space at the installation location.

[0094] Further, in the present embodiment, by suppressing the thickness of the base portion 11, as will be described below, an effect on the appearance of the holding device 1 can also be obtained.

[0095] FIG. 22 is a side view of the holding mechanism shown for explaining the effect on the appearance of the holding device obtained by suppressing the thickness of the base portion. In this FIG. 22, a state is shown in which the holding mechanism 10 in which the holding portion 12 is laid down and has a single plate shape together with the base portion 11 is pulled out from the apparatus main body 20 in the protruding direction D111.

[0096] As shown in this FIG. 22, in the present embodiment, by suppressing the thickness of the base portion 11, the thickness t11 is set to be substantially the same as the thickness t12 of the main body plate portion 124 other than the chucking portion 121 in the holding portion 12.

[0097] FIG. 23 is a perspective view of the holding device as viewed from the front side for explaining the external appearance effect of the holding device obtained by suppressing the thickness of the base portion. In FIG. 23, the upper side of the figure shows the state in which the holding mechanism 10 is housed in the device main body 20, and the lower side of the figure shows the state in which the holding mechanism 10 is pulled out from the device main body 20 and the holding portion 12 is erected. In addition, in this FIG. 23, the flange provided so as to surround the front panel portion 23 on the front side of the device main body 20, which is shown in FIGS. 1 and 2, is removed.

[0098] As shown in FIG. 23, the front panel portion 23 is provided with a notch 231 so as not to interfere with both the housed holding mechanism 10 and the pulled-out holding mechanism 10. In the housed state, the tip of the main body plate portion 124 of the holding portion 12 fits into the notch 231, and in the pulled-out state, the base portion 11 passes through the notch 231.

[0099] At this time, in the comparative example shown in FIG. 21, it is necessary to thicken the base portion 61 in order to accommodate the moving distance A61 of the rotating end of the rotating body 631. As a result, it becomes necessary to provide a deep notch in the front panel portion 23 so as not to interfere with the thickened base portion 61. On the other hand, regarding the holding portion (not shown), assuming that it has the same shape as that of the present embodiment, a gap will be formed between the main body plate portion of the holding portion thinner than the base portion 61 and the inner edge of the notch when housed. Such a gap is not preferable in terms of appearance.

[0100] On the other hand, in the present embodiment, as described above, since the thickness t11 of the base portion 11 is set to be substantially the same as the thickness t12 of the main body plate portion 124 of the holding portion 12, the gap that occurs in the above comparative example is suppressed, and a good appearance can be obtained.

[0101] Here, in the holding device 1 of the present embodiment, the protruding lock portion 13 includes a protruding lock torsion spring 135 that biases the locking portion 131 toward the locking position. Thereby, during use when the smartphone 5 is held and used, the locking portion 131 is constantly biased and locked to the device main body 20, so that it can be used in a stable state.

[0102] Further, in this embodiment, when the first moving body 132 moves the locking portion 131 to the unlocking position against the biasing force described above, it applies a force to the second moving body 133 to rotate it. On the other hand, when the locking portion 131 moves to the locking position, it rotates so as not to prevent the rotation of the second moving body 133. As a result, since the biasing force is utilized for the movement of the locking portion 131 to the locking position, the transmission of the force to the locking portion 131 by the first moving body 132 and the second moving body 133 only takes into account moving the locking portion 131 to the unlocking position. Thereby, the configuration of the mechanism related to the force transmission can be simplified, so that the manufacturing and assembly costs and labor of the holding device 1 can be reduced.

[0103] Also, in this embodiment, a rack 212b extending in the protruding / retracting direction D11 of the holding mechanism 10 is provided on the apparatus main body 20, and the locking portion 131 is configured to lock to the rack 212b in which the saw teeth 212b-1 are arranged linearly. In this embodiment, the length direction of this rack 212b is configured to coincide with the protruding / retracting direction D11 of the holding mechanism 10, and the storage space for the locking mechanism of the locking portion 131 in the holding device 1 is also suppressed. Thereby, further miniaturization of the holding device 1 is achieved.

[0104] Further, in this embodiment, the apparatus main body 20 further includes a storage lock portion 14 that locks the holding mechanism 10 that has retracted to the storage position. Thereby, the holding mechanism 10 can be stably stored in the storage position.

[0105] In addition, in this embodiment, the holding mechanism 10 includes a base portion 11 and a holding portion 12 pivotally supported by the base portion 11. With the pivotal movement of the holding portion 12 relative to the base portion 11, the first rotating body 132 and the second rotating body 133 rotate, thereby moving the locking portion 131. As a result, the rotation of the holding portion 12, which is an operation for the user to hold the smartphone 5, is utilized as an operation for locking and unlocking by the movement of the locking portion 131. Therefore, for locking and unlocking, it is possible to reduce the manufacturing cost by suppressing the number of parts, for example, as compared with the case where an operation button or the like is separately provided.

[0106] Note that the present invention is not limited to the embodiments described above, and includes other configurations and the like that can achieve the object of the present invention, and modifications and the like as shown below are also included in the present invention.

[0107] For example, in the above-described embodiment, as an example of the holding device according to the present invention, the holding device 1 as an in-vehicle device mounted on an instrument panel and used is exemplified.

Claims

【Claim 1】 The holding mechanism for the object to be held is a holding device that is supported by the apparatus main body so as to be slidable in and out, and includes a locking portion that is mounted on the holding mechanism and locks the holding mechanism at an arbitrary protruding position, wherein the locking portion includes a first rotating body that is pivotally supported by the holding mechanism and rotates upon receiving a predetermined operation, a second rotating body that rotates upon receiving a force directly or indirectly from the first rotating body as the first rotating body rotates, and a locking portion that moves between a locking position and a non-locking position where it locks to the apparatus main body as the second rotating body rotates. The holding device is characterized by this configuration.
