Description

  The present invention relates to a portable device holder for holding a portable device such as a mobile phone or a tablet.

  When a user holds a mobile device such as a mobile phone or a tablet with one hand, to avoid getting in the way of operation, hold the limited part such as the left or right edge or support the back. It is possible to become. However, such a way of holding tends to be unstable and may cause the portable device to fall. In addition, the user may get tired by holding the portable device.

  Therefore, a holder for a portable device has been conventionally proposed as an auxiliary tool when the portable device is held. As a typical example of a holder for a portable device, there is one provided with a suction cup and a finger hook portion that is fixed to the suction cup and can hook a finger (see, for example, Patent Documents 1 to 4).

  However, with conventional portable device holders, the suction force decreases as the suction cup is used, and sufficient suction force cannot function for relatively large portable devices such as tablets. There is a problem. Therefore, it cannot endure long-term use, and in some cases, the holder may fall off in the middle, and the portable device may be damaged.

  The present invention has been made in view of the above circumstances, and provides a holder for a portable device that can suppress dropout from a portable device for a long period of time and can be applied to a large-sized portable device. One of the main purposes is to provide it.

In order to solve the above-described problem, in the first invention, an adsorption device that is adsorbed with the back surface of the portable device as the adsorbed surface, and a finger hooking portion that is provided in the adsorption device and on which the finger of the portable device user is hung are provided. A portable device holder comprising:
The adsorption device is:
A suction cup having one surface in the thickness direction as a suction surface to be suctioned by the suction surface;
A shaft portion extending from the center of the other surface in the thickness direction of the suction cup to the side away from the other surface along the thickness direction;
A lever portion operated to move the shaft portion in the axial direction;
It has a mechanism for moving the shaft portion to the side away from the attracted surface in conjunction with the operation of the lever portion, and makes the attracted state in which the central portion of the attracting surface is separated from the attracted surface by the movement. An interlocking mechanism capable of
With
The finger hanging portion is provided by being biased to a position away from the shaft portion in the direction perpendicular to the axis,
The portable device can be held when a finger of a portable device user is hung on the finger rest portion in the suction state.

  According to the first aspect of the invention, first, the portable device holder is sucked by the suction surface of the suction cup to the back surface of the portable device that is the suction surface. In addition, if the lever is operated, the center of the suction surface is separated from the surface to be attracted, and the closed space between the surface to be attracted and the surface to be attracted by the separation becomes almost vacuum and the suction force Will be strengthened. Thereby, the drop-off from the portable device can be suppressed for a long time, and it can be applied to a relatively large portable device.

  Furthermore, since the finger hook is provided in a state shifted from the shaft portion, the finger hook is not too far from the attracted surface, and it is easy for a portable device user to hold the finger when using the portable device holder. Can be done.

In 2nd invention, the said finger-hanging part is the cyclic | annular part formed in the cyclic | annular form which can let a portable machine user's finger pass,
The suction surface side of the annular portion is set at substantially the same height as the suction surface when viewed in a direction perpendicular to the suction surface.

  According to the second aspect of the invention, since the finger-hanging portion is formed in an annular shape, it is not necessary to hold it with a plurality of fingers, and the portable device can be held in an easy state. In addition, since there is a place where the finger is caught around the finger that has passed through the annular portion, the risk of accidentally dropping the portable device can be reduced.

  Further, in this configuration, the attracted surface side of the annular portion is substantially in contact with the attracted surface, so that the contact can improve the sense of stability in holding the portable device with the finger hook. Furthermore, the annular portion is set at a position close to the attracted surface, and the effect of the latter stage of the first invention in which the finger can be easily hooked is further enhanced.

  In a third aspect of the present invention, the finger of the portable device user comes into contact with the side of the annular portion that is further away from the shaft portion in the direction orthogonal to the axis and the side that is away from the attracted surface. A protrusion that suppresses movement to the side away from the attracted surface is formed.

  According to the third aspect of the invention, for example, when the ring finger is passed through the annular portion, the little finger is disposed outside the annular portion, but the little finger is less likely to be separated from the attracted surface due to the presence of the protrusion. The portable device can be securely held from the back side in a stable state.

  According to a fourth aspect of the present invention, a first arc-shaped portion that protrudes toward the shaft portion side is formed near the attracted surface of the protrusion in the annular portion.

  According to the fourth invention, for example, when the ring finger is passed through the annular portion, the little finger is arranged outside the annular portion, but the little finger is arranged in a state smoothly guided by the first arc-shaped portion. Therefore, the little finger is naturally arranged at the position, the restriction effect by the protrusion is easily exhibited, and the finger does not easily hurt even if held for a long time.

  In a fifth aspect of the present invention, a second arcuate portion that protrudes toward the attracted surface is formed on a side of the annular portion that is away from the attracted surface near the shaft portion.

  According to the fifth invention, for example, when the ring finger is passed through the annular portion, the middle finger is arranged on the shaft portion side of the annular portion, but the middle finger is smoothly guided by the second arc-shaped portion. Since the middle finger is naturally placed at that position, the holding effect is easily exhibited, and the finger is less likely to hurt even if held for a long time.

  In a sixth aspect of the present invention, the maximum separation position of the finger-hanging portion from the suctioned surface is set to be substantially the same as the maximum separation position of the suction device from the suctioned surface.

  According to the sixth aspect of the present invention, the portable device holder can function as a pedestal when the portable device is not held by hand but is intended to be placed obliquely. Moreover, since the portable device holder is formed in an oblong shape as a whole and has a shape close to a rectangle, it is possible to secure a wider portion that comes into contact with the placement surface on which the portable device is placed, and to be placed obliquely in a stable state. be able to.

  In a seventh invention, a gel layer is formed on the suction surface side of the suction cup.

  According to the seventh aspect, since the gel layer is provided on the suction cup, the adsorption effect using the suction cup is more easily exhibited by the adhesive force of the gel layer.

  The eighth invention is characterized in that the finger-hanging portion also serves as the lever portion.

  According to the eighth aspect of the invention, since the lever portion also serves as the finger hook portion, an increase in the number of parts can be suppressed. In addition, when both the lever part and the finger rest part exist separately, it must be considered that the finger interferes with the lever part when the finger is placed on the finger rest part. Can be eliminated.

In a ninth invention, the lever portion is provided so as to be rotatable in the circumferential direction about the axis of the shaft portion,
The interlocking mechanism portion includes a cam mechanism that moves the shaft portion in an axial direction so as to change between the attracted state and the released state by the rotation.

  According to the ninth aspect of the present invention, the lever portion that also serves as the finger-hanging portion is turned between the suction state and the released state by rotating the lever portion in the circumferential direction of the shaft portion. For this reason, even if a force is applied to the finger-hanging portion to the side away from the attracted surface when the finger is hooked, the force is not applied to the side to release the suction state. Therefore, the suction state is not inadvertently released.

  Below, 1st Embodiment of the holder for portable devices is described based on FIGS. In the first embodiment, for example, a tablet that is a portable device that is slightly larger than a mobile phone is to be held, and is mainly used to hold the tablet with one hand.

  First, the configuration of the portable device holder will be described with reference to FIGS. FIG. 1 is a front view showing a portable device holder according to the first embodiment, and FIG. 2 is a plan view thereof. 3 is a cross-sectional view taken along the line AA in FIG. 2, in which (a) shows a primary adsorption state and (b) shows a secondary adsorption state. In the following description, when the vertical and horizontal directions are specified, the state shown in FIGS. 1 and 3 is used as a reference.

  As shown in FIGS. 1 and 2, the portable device holder 10 includes a holder body 11, a suction cup 21, and a lock lever 31 as its basic configuration.

  The holder body 11 is made of a rigid material such as hard resin or metal, and has a circular shape in plan view. The holder main body 11 has a skirt-like portion 12 and a rising portion 13. The skirt-like portion 12 has an annular outer surface that is inclined from the center side of the circle in plan view toward the outer edge side. The rising portion 13 is provided so as to rise from the upper end edge of the skirt-like portion 12 at the inner central portion of the skirt-like portion 12, and the upper surface of the rising portion 13 is a flat portion 14. An inner space 15 is formed inside the skirt-like portion 12 and the rising portion 13 constituting the holder main body 11 as shown in the cross-sectional view of FIG.

  The suction cup 21 is formed in a disk shape having a diameter that is slightly larger than the outer edge of the holder body 11, and the holder body is covered with the skirt-like portion 12 of the holder body 11. 11 is supported. The circle of the suction cup 21 is coaxial with the circle of the holder body 11.

  The suction cup 21 has a suction cup body 22 and a gel layer 23. The suction cup body 22 is made of an elastic material such as resin. The gel layer 23 is an adhesive gel formed of a resin such as silicon. The gel layer 23 is attached to the surface of the suction cup body 22 opposite to the one surface covered with the skirt-like portion 12 with an adhesive or the like. The surface of the gel layer 23 opposite to the suction cup body 22 is the suction surface 24 of the suction cup 21, and the back surface Ta of the tablet T that is the suction surface (opposite to the image display surface) by the adhesive force of the gel layer 23. The portable device holder 10 is adsorbed on the side surface. This is the primary adsorption state.

  A removal operation piece 25 extending outward in the radial direction is provided on the outer edge of the suction cup body 22. By using this removal operation piece 25, the portable device holder 10 in the primary suction state can be peeled off from the back surface Ta.

  The lock lever 31 is a lever operated to change from the primary suction state to the secondary suction state. The lock lever 31 is provided so as to be rotatable with respect to the holder body 11 around the central axis of the holder body 11 and the suction cup 21. After the portable device holder 10 is attracted to the back surface Ta of the tablet T, when the lock lever 31 is manually rotated 90 degrees from the initial position to the lock position (see FIG. 2), the secondary suction state is obtained. In this secondary adsorption state, the adsorption force on the adsorption surface 24 is strengthened compared to the primary adsorption state.

  The configuration of the lock lever 31 and the configuration in which the lock lever 31 is turned to the secondary suction state by the rotation operation will be described in a little more detail.

  The lock lever 31 is formed of a rigid material such as hard resin or metal, and includes a rotation base portion 32 and a rotation lever portion 33 for rotation operation corresponding to the lever portion. Among these, the rotation base 32 is formed in a cylindrical shape whose diameter gradually decreases toward the side opposite to the adsorption surface (upper side). The rotation base 32 is placed on the flat portion 14 of the rising portion 13 in the holder body 11 so as to be coaxial with the holder body 11 and the suction cup 21. The upper opening of the rotation base 32 is closed by a dome-shaped lid member 34.

  As shown in the sectional view of FIG. 3 (a), an inclined cam surface 35 is formed inside the rotation base 32, and a cam mechanism is formed together with the cam shaft 42 of the central shaft 41 described later. Yes. Further, the interlocking mechanism portion is constituted by the rotation base portion 32 and the cam mechanism. The inclined cam surface 35 is also formed on the front side of the illustrated paper surface.

  The central shaft portion 41 is provided on the suction cup 21 and is a member corresponding to the shaft portion. The suction cup body 22 of the suction cup 21 is formed with a bulging portion 26 having a circular shape in plan view at the center thereof, and the bulging portion 26 swells on the side opposite to the suction surface (upper side) and is thicker than the outer peripheral side. Has been. A central shaft portion 41 is erected at the central portion of the bulging portion 26 (the central portion of the suction cup 21) so as to be perpendicular to the plane (that is, in the thickness direction of the suction cup main body 22). . The central shaft portion 41 is formed of a rigid material such as hard resin or metal, and the end portion on the suction surface side (lower side) of the central shaft portion 41 is embedded in the bulging portion 26 of the suction cup body 22.

  The central shaft portion 41 is accommodated in the internal space 15 of the holder body 11 and is inserted through the insertion hole 16 provided in the flat portion 14, and the upper end portion projects into the rotation base portion 32 of the lock lever 31. The rotating base 32 is accommodated. The protruding portion into the rotation base 32 is in contact with the inner surface of the rotation base 32. By this contact, the rotation base 32 placed on the flat surface portion 14 is integrally attached to the holder main body 11, and the coaxial state of the holder main body 11, the rotation base 32, and the central shaft portion 41 is maintained. .

  A cam shaft 42 is provided at the upper end portion of the central shaft portion 41 and engages with the inclined cam surface 35 provided on the rotation base portion 32. In the internal space 15 of the holder main body 11, a conical coil spring 43 is provided between the flat surface portion 14 and the bulging portion 26 of the suction cup main body 22. The coil spring 43 is inserted through the central shaft portion 41, and the cam shaft 42 is pressed against the inclined cam surface 35 by the biasing force. Thereby, the engagement state of the cam shaft 42 and the inclined cam surface 35 is maintained.

  When the lock lever 31 is rotated from the initial position to the lock position by having the above-described configuration, the following operation occurs.

  In other words, the cam mechanism configured by the inclined cam surface 35 and the cam shaft 42 causes the central shaft portion 41 to move upward as the cam shaft 42 follows the displacement of the inclined cam surface 35. Then, as shown in FIG. 3B, the central portion of the suction cup 21 to which the lower end portion of the central shaft portion 41 is attached moves upward, and the suction surface 24 is separated from the back surface Ta of the tablet T in that portion. To do. The suction surface 24 is maintained in a state of being attracted to the back surface Ta of the tablet T at the outer peripheral portion, and is in a secondary suction state in which an inner space portion 44 that is a closed space is formed. Since the inner space portion 44 is in a substantially vacuum state, the suction surface 24 in the secondary suction state can obtain a stronger suction state than the primary suction state.

  As described above, in the portable device holder 10, the suction device K is configured by the members including the holder body 11, the suction cup 21, the rotation base portion 32 of the lock lever 31, the lid member 34, and the central shaft portion 41. Yes. And the holder 10 for portable devices is firmly adsorb | sucked by the back surface Ta of the tablet T by this adsorption | suction apparatus K. FIG.

  By the way, the holder 10 for portable devices of this embodiment has the characteristic in the said rotation lever part 33 of the lock lever 31 in addition to the above basic structures. That is, the rotation lever portion 33 is not only a function as an operation lever for making the secondary suction state, but also when the portable device user (user) passes the finger or hooks the finger when holding the tablet T. The structure is also used as a finger-hanging part. Next, the configuration of the rotating lever portion 33 will be described.

  Returning to FIGS. 1 and 2, the rotation lever portion 33 extends from the rotation base portion 32 in a direction (horizontal direction) orthogonal to the central axis thereof, and is disposed beside the adsorption device K. Yes. More specifically, the rotating lever portion 33 has a lever base portion 51 and an annular portion 52.

  The lower end edge of the lever base 51 extends from the lower end of the rotation base 32 along the rising portion 13 and the skirt-like portion 12 of the holder body 11 and reaches the lower end of the skirt-like portion 12. Further, the upper end edge of the lever base 51 is formed in a concave shape and an arc shape toward the suction surface 24 side, and serves as a middle finger hooking portion 53 on which the middle finger is placed.

  The annular portion 52 is provided outside the lever base 51, and is formed with a ring finger passage hole 54 through which the ring finger can pass. The lower edge portion 52a of the annular portion 52 extends further downward than the lower end of the lever base 51, and the lowermost end portion thereof is substantially the same as the suction surface 24 when viewed in the direction (vertical direction) perpendicular to the suction surface 24. Is set to the height position. In the secondary suction state, the lowermost end portion of the lower edge portion 52a is substantially in contact with the back surface Ta of the tablet T (see FIG. 5 described later).

  The upper edge portion 52b of the annular portion 52 has a shape that extends substantially in the horizontal direction after rising from the middle finger hanging portion 53 with a gentle upward slope. The upper edge portion 52b is formed such that the height from the suction surface 24 is lower than the top portion of the lid member 34 that closes the rotation base portion 32 and is at the same height. (See FIG. 5 described later).

  Further, the outer edge portion 52c of the annular portion 52 is formed so as to extend from the lower edge portion 52a in the vertical direction (upward direction) with respect to the suction surface 24 and then extend outward. For this reason, the outer edge portion 52c and the upper edge portion 52b are joined at an acute angle, whereby the protrusion 55 is formed. Since the outer edge portion 52c has such a shape, the suction surface 24 side of the projection 55 has a concave arc shape, and the arc-shaped portion serves as a little finger hook portion 56 for hooking the little finger.

  Next, the usage form of the portable device holder 10 including the lock lever 31 having the above-described configuration will be described with reference to FIGS. 4A and 4B are diagrams showing the back surface Ta of the tablet T to which the portable device holder 10 is adsorbed. FIG. 4A shows the primary adsorption state with the portable device holder 10 attached, and FIG. 4B shows the secondary adsorption state. This shows a state in which a finger is put on the portable device holder 10 (assuming that the dominant hand is a right hand). FIG. 5 is a side view showing the X view in FIG. 4B, FIG. 6 is a perspective view showing a usage pattern of the portable device holder 10, and FIG. 7 is another drawing of the portable device holder 10. It is a partial side view which shows a usage pattern. In the following description, the vertical and horizontal directions are based on the normal usage pattern of the tablet T, and FIGS. 4 to 7 are also illustrated based on the usage pattern.

  First, as shown in FIG. 4A, the portable device holder 10 is primarily sucked to the back surface Ta of the tablet T by the suction surface 24. As the suction position in this case, as shown in the drawing, it is preferable that the suction surface 24 is disposed at a position slightly to the right of the left and right centers in the vicinity of the center portion in the vertical direction on the back surface Ta. In this primary suction stage, the lock lever 31 is sucked so as to be substantially parallel to both the upper and lower sides of the tablet T and to the right. At this time, if the adsorption surface 24 is slightly pressed, the adsorption force due to the adhesive force of the gel layer 23 is increased.

  Next, the lock lever 31 is rotated 90 degrees clockwise from the initial position toward the lock position. Thereby, as above-mentioned, the holder 10 for portable devices will be in a secondary adsorption state, and adsorption | suction power is raised.

  As shown in FIG. 4B, the lock lever 31 of the portable device holder 10 in the secondary suction state is in a downward state. In this state, the left ring finger F4 is passed through the ring finger passage hole 54 from the right side of the back surface Ta, the middle finger F3 is placed on the middle finger hook portion 53, and the little finger F5 is placed along the little finger hook portion 56. Further, the index finger F2 is placed on the skirt 12 with the rotation base 32 sandwiched between the index finger F2 and the middle finger F3. FIG. 5 shows the states of the fingers F2 to F5 at this time.

  Here, as shown by the reference line L1 in FIG. 5, in the portable device holder 10, the suction device K and the rotation lever portion 33 are separated from the back surface Ta (same surface as the suction surface 24) of the tablet T. The height is almost the same. That is, the height to the apex portion of the lid member 34 in the suction device K and the height to the protrusion 55 of the rotating lever portion 33 are set to be substantially the same. In the illustration of FIG. 5, the lower edge 52 a of the annular portion 52 is in contact with the rear surface Ta at the lower end, but in reality, there is a slight gap, and the rotation of the rotation lever portion 33. The sliding with the back surface Ta at the time is suppressed.

  When using the tablet T, the tablet T is turned to the front from the state where the above-mentioned finger is hung. Then, as shown in FIG. 6, the tablet T can be held with one hand of the left hand by supporting the edge of the left side of the tablet T with the palm of the left hand and the thumb F1.

  In addition, a tablet using a configuration in which the turning lever portion 33 is provided so as to be separated from the central axis of the suction device K, and both the turning lever portion 33 and the suction device K are set at substantially the same height. Horizontal placement with the left side Tb of T on the lower side is also possible. In this case, as shown in FIG. 7, the lid member 34 in the suction device K and the upper edge portion 52 b of the annular portion 52 in the rotating lever portion 33 (disposed on the lower side in this usage mode) are in the lateral direction. Used as a wide pedestal.

  In addition, when removing the holder 10 for portable devices from the tablet T, what is necessary is just to perform the reverse of the time of mounting | wearing. That is, the lock lever 31 disposed at the lock position is rotated to return to the initial position. Then, the entire surface of the suction surface 24 is again attracted to the back surface Ta of the tablet T, and the secondary suction state is released. Thereafter, the holder 10 for the portable device can be removed by peeling the suction surface 24 from the back surface Ta while pinching the removal operation piece 25.

  As described above, according to the portable device holder 10 of the first embodiment, the following advantageous effects can be obtained.

  (1) The portable device holder 10 is primarily adsorbed to the back surface Ta of the tablet T by the suction surface 24 of the suction cup 21. In addition, when the lock lever 31 is rotated, the central portion of the suction surface 24 is in a secondary suction state separated from the back surface Ta, and the suction force is strengthened by the vacuum state of the inner space portion 44 generated thereby. For this reason, it can suppress for a long time that the holder 10 for portable devices falls from the tablet T, and can be applied also to a comparatively large portable device like the tablet T.

  (2) The rotating lever portion 33 having a finger-hanging portion (the middle finger-hanging portion 53 or the like) through which the user's finger is passed or hooked is provided in a state of being shifted from the central shaft portion 41. For this reason, a finger hook part does not leave | separate too much from the back surface Ta of the tablet T, and when a user uses the holder 10 for portable devices, a finger hook can be performed easily.

  (3) Since the ring finger is inserted into the ring finger through hole 54 of the annular part 52 through the ring finger F4, it is not necessary to hold the finger holding part with a plurality of fingers, and the tablet T is in an easy state. Can have in. Moreover, since the ring finger 52 is hooked on the annular portion 52 when the tablet T is held, the risk of the tablet T being dropped carelessly can be reduced. For example, when the tablet T is held while sleeping like an inpatient in a hospital, this effect becomes more remarkable.

  (4) The lower edge portion 52 a of the annular portion 52 has a lowermost end portion set at substantially the same height as the suction surface 24. In the secondary suction state, the lowermost end portion thereof is substantially on the same plane as the suction surface 24 and is in a state of being substantially in contact with the back surface Ta of the tablet T. For this reason, when a finger is put on the rotating lever portion 33 to support the back surface Ta side, the lowermost end portion of the lower edge portion 52a abuts on the back surface Ta to provide support, thereby improving stability. In addition, the ring finger hole 54 of the annular portion 52 is set at a position close to the back surface Ta of the tablet T, and the effect (2) that the ring finger F4 can be easily hooked is further enhanced.

  (5) Since the protrusion 55 is formed on the rotation lever portion 33, the little finger F5 disposed outside the annular portion 52 when the ring finger F4 is passed through the ring finger passage hole 54 is caused by the presence of the protrusion 55 to form a tablet. It becomes difficult to separate from the back surface Ta of T. Thereby, the tablet T can be firmly held in a stable state.

  (6) On the outer edge portion 52 c of the annular portion 52, a small finger hook portion 56 having an arc shape is formed near the suction surface 24 of the protrusion 55. For this reason, when the ring finger F4 is passed through the ring finger passage hole 54, the little finger F5 disposed outside the annular portion 52 is smoothly guided by the little finger hooking portion 56. As a result, the little finger F5 is naturally arranged at that position, the restriction effect by the protrusion 55 is easily exhibited, and even if the finger is held for a long time, the finger is less likely to hurt.

  (7) On the upper edge of the lever base 51, an arcuate middle finger hook 53 is formed. For this reason, when the ring finger F4 is passed through the ring finger passage hole 54, the middle finger F3 disposed on the central shaft portion 41 side of the annular portion 52 is disposed in a state of being smoothly guided by the middle finger hook portion 53. As a result, the middle finger F3 is naturally placed at that position and the holding effect is easily exhibited, and even if the finger is held for a long time, the finger is less likely to hurt.

  (8) The height of the rotating lever portion 33 from the suction surface 24 is set to be substantially the same as the height from the suction surface 24 of the suction device K. For this reason, the holder 10 for portable devices can be functioned as a pedestal when the tablet T is not held by hand but is inclined. Moreover, since the portable device holder 10 is formed in a horizontally long shape and has a shape close to a rectangular shape, a wider portion can be secured in contact with the placement surface on which the tablet T is placed, and the portable device holder 10 can be placed obliquely in a stable state. can do.

  (9) The suction cup 21 is provided with a gel layer 23, and an adsorption surface 24 is formed by the gel layer 23. Thereby, since the primary adsorption state by the adhesive force of the gel layer 23 is obtained, the adsorption effect using the suction cup 21 is more easily exhibited, and the lock lever 31 is also easily rotated.

  (10) The rotation lever portion 33 is configured not only to function as an operation lever for making the secondary suction state, but also to serve as a finger hooking portion through which a user passes a finger or hooks a finger. For this reason, the increase in the number of parts can be suppressed. In addition, when both the control lever and the finger rest part exist separately, it is necessary to consider that the finger interferes with the control lever when the finger is put on the finger rest part. Can do.

  (11) The rotation lever portion 33 is configured to change between a secondary suction state and a released state thereof by rotation by a cam mechanism having an inclined cam surface 35 and a cam shaft 42. Since the rotation is necessary to cancel the secondary adsorption state, even when a force is applied toward the side away from the back surface Ta of the tablet T when the finger is applied to the rotation lever 33, it cancels the secondary adsorption state. There is no power to the side. Thereby, the secondary adsorption state is not inadvertently released.

  In addition, it is not restricted to 1st Embodiment demonstrated above, For example, it can also implement in the form shown as another example below.

  (A) In the first embodiment, the rotation lever portion 33 of the lock lever 31 is also used as a finger hooking portion such as the ring finger passage hole 54. However, the lock lever 31 and the finger hooking portion are provided separately. May be adopted. The portable device holder of the second embodiment and the third embodiment, which is an example of the configuration, will be briefly described with a focus on a configuration different from the first embodiment.

  (A-1) As shown in FIG. 8, the holder 60 for portable devices of 2nd Embodiment is provided with the holder main body 61, the suction cup 62, the lock lever 63, and the finger hook part 64. As shown in FIG. The lock lever 63 is erected on the top portion of the holder main body 61 formed in a dome shape, and a central shaft portion 65 attached to the suction cup 62 is connected. The lock lever 63 is rotatable about a direction orthogonal to the central shaft portion 65 as a central axis, and a cam portion 63a is provided on the holder body 61 side. When the lock lever 63 is tilted toward the holder main body 61 as shown in the drawing while using the cam portion 63a as a fulcrum, the central shaft portion 65 moves to the anti-suction surface side and is pulled up, and the central portion of the suction surface 62a is Separated from the surface to be attracted (the back surface Ta of the tablet T). Thereby, a secondary adsorption state is obtained as in the first embodiment. In the second embodiment, the interlocking mechanism portion is configured by the cam portion 63a and the engaging portion of the holder main body 61 with the cam portion 63a.

  At the tip of the lock lever 63, a protruding piece 66 that is bent obliquely is provided. The projecting piece 66 functions as a hook portion when the lock lever 63 is raised to release the secondary suction state.

  On the other hand, the finger hook portion 64 is provided on the outer surface of the holder body 61 separately from the lock lever 63. The finger hook portion 64 is an annular portion that is formed in an annular shape that allows the ring finger F4 to pass therethrough, and the inside thereof is a ring finger hole 67. As indicated by the reference line L2, the height from the suction surface 62a of the finger hanging portion 64 is substantially the same as the height of the lock lever 63 in the tilted state. On the outer edge portion 64a of the finger hanging portion 64, a little finger hanging portion 68 having a convex arc shape toward the central shaft portion 65 is formed in the same manner as in the first embodiment.

  In the portable device holder 60 having the above-described configuration, the finger-hanging portion 64 faces the lower side of the tablet T and is attracted to the back surface Ta, and then the lock lever 63 is tilted to be in the secondary adsorption state. The arrangement of the portable device holder 60 on the back surface Ta is preferably the same position as the portable device holder 10 of the first embodiment.

  In this state, the ring finger F4 of the left hand is passed through the ring finger hole 67 from the right side of the back surface Ta as in the portable device holder 10 of the first embodiment. Then, the middle finger F <b> 3 is placed between the base end portion of the lock lever 63 and the finger hook portion 64, and the little finger F <b> 5 is placed along the little finger hook portion 68. The index finger F2 is placed on the lock lever 63 so that the proximal end portion of the lock lever 63 is sandwiched between the index finger F2 and the middle finger F3. At this time, the protruding piece 66 of the lock lever 63 functions as a support for the index finger F2.

  Also with the portable device holder 60 of the second embodiment, the same effects as those of the portable device holder 10 of the first embodiment are obtained except that the lock lever 63 and the finger hook portion 64 are separate. be able to.

  (A-2) As shown in FIG. 9, the portable device holder 70 of the third embodiment also includes a holder body 71, a suction cup 72, a lock lever 73, and a finger hook portion 74. The holder main body 71 is formed in a hemispherical shape, and an arcuate lock lever 73 is provided at the top of the holder main body 71 in a state of being flipped up.

  A central shaft portion 75 attached to the suction cup 72 is connected to the lock lever 73. The lock lever 73 is rotatable about a direction orthogonal to the central shaft portion 75 as a central axis. When the lock lever 73 is tilted toward the holder main body 71 as shown in the drawing, the lock lever 73 also forms a part of a hemisphere. . At the same time, the central shaft portion 75 moves to the side opposite to the suction surface and is pulled up, and the central portion of the suction surface 72a is separated from the surface to be suctioned (the back surface Ta of the tablet T). Thereby, a secondary adsorption state is obtained as in the first and second embodiments. In the third embodiment, an interlocking mechanism portion is provided at the rotation center portion of the lock lever 73.

  On the other hand, the finger hanging portion 74 has a finger hanging base portion 76, a finger hanging shaft portion 77 and a finger hanging ball portion 78. The finger-hanging base portion 76 is formed in an arc shape and protrudes from the outer surface of the holder main body 71 to the side opposite to the suction surface. A finger hooking shaft portion 77 extends in a direction away from the central shaft portion 75 and obliquely toward the anti-suction surface side at the tip portion of the finger hanging base portion 76, and a finger hanging ball having a spherical shape at the tip of the finger hanging shaft portion 77 A portion 78 is provided.

  In the portable device holder 70 having the above-described configuration, after the finger hooking portion 74 is attracted to the back surface Ta so as to be on the lower side of the tablet T, the lock lever 73 is tilted to be in the secondary adsorption state. The arrangement of the portable device holder 70 on the back surface Ta is arbitrary.

  In this state, the tablet T can be held by supporting the portable device holder 70 by sandwiching the finger hanging shaft portion 77 between two fingers. According to the third embodiment, unlike the portable device holders 10 and 60 of the first embodiment and the second embodiment, the finger hook portion 74 is not formed in an annular shape. However, the effect that the holder 70 for portable devices can be adsorbed to the tablet T in a strong secondary adsorption state and can be easily held is obtained.

  (B) In the first embodiment, the rotation lever portion 33 has the annular portion 52 and the ring finger passage hole 54 is formed, but either the lower edge portion 52a or the outer edge portion 52c of the annular portion 52 is formed. Either or both may be omitted and a non-annular configuration may be employed. For example, if only the upper edge portion 52b is configured, it is conceivable to form it in an arc shape (arch shape). Even in this non-annular configuration, by having at least the upper edge portion 52b, the non-annular portion can function as a finger hook portion for hooking the ring finger F4.

  (C) In the first embodiment, a protrusion 55 is formed on the annular portion 52 of the rotating lever portion 33, and a little finger hook portion 56 is formed on the outer edge 52c. A configuration in which the portion 55 and the little finger hook portion 56 are omitted may be employed. For example, it is conceivable that the outer edge is an annular portion having a circular shape or an elliptical shape. Although the function of stabilizing the little finger F5 is inferior to the configuration having the little finger hook portion 56, it is possible to stabilize the little finger F5 by bringing the little finger F5 into contact with the outer edge portion of the annular portion 52 or the like.

  Moreover, even if it is the structure which has the little finger hook part 56, you may employ | adopt the shape different from the circular arc shape of the said 1st Embodiment. For example, the structure which has the little finger hook part which makes the obtuse-angled-ku shape which becomes convex at the ring finger penetration hole 54 side can be considered.

  (D) In the first embodiment, the middle finger hook portion 53 is formed at the upper end edge of the lever base portion 51 in the rotating lever portion 33. However, a configuration in which this is omitted may be employed. This is because even if this is omitted, it is possible to place the middle finger F3 on the upper end edge of the lever base 51. Moreover, even if it is the structure which has the middle finger-hanging part 53, you may employ | adopt the shape different from the circular arc shape of the said 1st Embodiment. For example, it is conceivable to form an obtuse square-shaped shape or a trapezoidal shape convex toward the suction surface 24 side.

  (E) In the said 1st Embodiment, although both the adsorption | suction apparatus K and the rotation lever part 33 are set to the substantially same height (refer FIG. 5), it set so that each might become a different height. A configuration may be adopted. For example, if the height of the suction device K is set to be higher, the middle finger F3 and the index finger F2 can be easily sandwiched, which can contribute to stabilization of holding. On the other hand, if the height of the turning lever portion 33 is set higher, for example, the depression of the middle finger hook portion 53 can be formed deeper and the finger hook of the middle finger F3 can be further stabilized.

  In addition, the structure set to such an alternate height in this way can be similarly adopted in the portable device holder 60 of the second embodiment described above.

  (F) In the said 1st Embodiment, although the gel layer 23 is provided in the suction cup 21, the structure which abbreviate | omitted this gel layer 23 may be employ | adopted. This is because even if there is no primary adsorption state using the adhesive force of the gel layer 23, a strong adsorption effect can be obtained by the rotation of the lock lever 31. However, since the adsorption effect is remarkably enhanced by the synergistic effect of the primary adsorption by the gel layer 23 and the secondary adsorption by the rotation of the lock lever 31, it is practically preferable to have both configurations.

  (G) In the first embodiment, each finger hanging portion (the middle finger hanging portion 53, the ring finger passing hole 54, and the little finger hanging portion 56) provided in the rotating lever portion 33 specifies a finger to be hung there. This proposes an optimal usage mode. For this reason, you may use it by putting a different finger on each part. This also applies to the portable device holders 60 and 70 according to the second and third embodiments described above.

  (H) The orientation of the lock lever 31 in the primary suction stage determined in consideration of the arrangement position of the portable device holder 10 on the back surface Ta of the tablet T and the rotation to the lock position is arbitrary, and the usage pattern of the user It may be attached to an appropriate position and orientation depending on the situation. For example, in the first embodiment, it is assumed that the dominant hand is the right hand, but when the opposite hand is the left hand, the portable device holder 10 is arranged at a position slightly to the left of the left and right center on the back surface Ta. Is preferred.

  (I) In the first embodiment, the tablet T, which is a relatively large portable device, has been described as an example of a portable device. However, the portable device is not limited to this, and for example, a cellular phone, a portable music player, or the like It may be.
