Abstract

[Problem] Although conventional portable electronic terminal holders have a fall prevention function, the holders are not intended to enhance operability with one-hand thumb input. Further, adaptability to a large-sized screen type is unsatisfactory. [Solution] A lever is attached to a wheel rotating about a shaft attached to the portable electronic terminal, is pulled away from the side and is held between fingers for use, or is stored along the rear surface when not in use. By means of this mechanism, the present invention enhances a thumb input operability and adaptability to a large-sized screen type while allowing secure holding of a portable electronic terminal, and also exhibits easy storage.

Description

Portable electronic terminal holder

The present invention relates to a holder and a holding method for ensuring the holding of a mobile phone by hand and improving the operability.

Recently, the screen size of a type of mobile phone called a smartphone has gradually increased. The screen size is generally expressed in terms of the length of the diagonal line expressed in inches. Conventionally, there are many about 4 inches. Recently, 5 inches or more are increasing. Of course, the overall size, which was conventionally about 12 cm in length and about 6 cm in width, is now larger than 13 cm in length and 7 cm in width. *

Smartphones use a method in which the screen portion is pressed by a finger. That is, the display unit also serves as the input unit. The input range covers the entire screen. Usually, when inputting, there are a method using both hands and a method using only one hand. Using both hands, supporting the device with one hand and typing with the fingers of the other hand, both hands will be blocked, so you can do input while holding a bag or typing while writing with a pencil. I can't. In the method using only one hand, a method of supporting a smartphone by placing four fingers from the index finger to the little finger other than the thumb on the back side of the smartphone and pressing a desired position on the screen with the thumb is employed. In this case, if the position pressed with the thumb is closer to the end or the force pressed with the thumb is too strong, the smartphone slips from the hand and falls. In particular, as the screen of a smartphone becomes larger than 5 inches, the area supported by the four fingers from the index finger to the little finger other than the thumb becomes relatively small compared to the size of the back surface, and the smartphone slips off the hand. It has become easier. *

In order to prevent the falling from the hand, it has been conventionally performed to attach a ring-shaped finger pointing to the back surface of the smartphone. The back surface perspective view of the smart phone which attached the ring to FIG. 15 is shown. In FIG. 15, a base 22 is attached to substantially the center of the back surface 4 of the smartphone 1, and a ring receiver 23 is attached to the center of the base 22 so as to be capable of rotating. A ring 21 is passed through a hole 24 formed in the ring receiver 23. The ring 21 is movable in the hole 24. *

The perspective view of the back surface at the time of use of the portable electronic terminal which attached the ring to FIG. 16 is shown. The ring 21 is usually used with the middle finger 33 inserted. Any other finger of the index finger 32, ring finger 34, and little finger 35 may be inserted into the ring 21. The ring 21 can pass a finger at a free position suitable for each finger by the rotation of the ring receiver 23 and the movement of the ring 21 itself. By inserting one finger, the smartphone 1 can be prevented from falling from the hand without being held between the thumb 31 and another finger. *

However, when the user tries to push the far end of the screen with the thumb 31, the finger placed in the ring 21 is pulled out and the smartphone 1 is likely to be dropped. That is, the holding is unstable and there is a problem in application to a smartphone with a large screen. *

The present invention solves such a problem and can hold a portable electronic terminal that can be held stably even with a large-sized smartphone and does not fall, and can be input in a wide range with the thumb of one hand while holding it with one hand. It provides tools.

JP-A-6-318972 JP 2002-152352 A Patent Registration No. 5370600

As smartphones grow larger, it has become easier to fall out of their hands. Further, the conventional fall prevention device has a narrow range of stable input. *

The present application is intended to solve such a problem, and to provide a portable electronic terminal holder that can be stably held even by a large-sized smartphone, does not fall, and can input a large range with a thumb.

In order to achieve the above object, the present invention is a substantially rectangular flat plate-like shape that is attached to the back surface of a portable electronic terminal having a front surface with an input portion and a back surface thereof, and has a rotation center axis perpendicular to the back surface. A flat shaft, a wheel that rotates around the shaft along the back surface, a retaining portion that is attached to the shaft and prevents the wheel from falling off the shaft, and is connected to an outer periphery of the wheel to connect the shaft And a lever perpendicular to the rotation center axis. The lever can be protruded from the side surface or retracted along the back surface depending on the rotation angle of the wheel.

According to the present invention, by holding the lever between fingers other than the thumb, it is possible to hold the lever stably, and it is possible to input in a wide input range with the thumb of one hand. It's easy to get in after you use it. With simple means, the portable electronic terminal can be held with one hand and the portable electronic terminal can be handled with one hand.

Embodiments of the present invention will be described below with reference to the drawings.

The configuration of the portable electronic terminal holder according to the first embodiment will be described with reference to FIGS. FIG. 1 is a perspective view of the back surface of the first embodiment of the portable electronic terminal holder of the present invention. FIG. 2 is a perspective view of the back surface when the first embodiment of the portable electronic terminal holder of the present invention is not used. FIG. 3 is a cross-sectional view of the first embodiment of the portable electronic terminal holder of the present invention. FIG. 4 is a perspective view including a hand when the first embodiment of the portable electronic terminal holder of the present invention is used. *

In FIG. 1, a smartphone 1 as a portable electronic terminal has a rectangular flat plate shape as a whole, and includes a front surface 2 (not shown) having a display / input unit, a back surface 4 on the opposite side, and four in between. It has

side surfaces

5a, 5b, 5c and 5d. The back surface 4 and the side surfaces 5a, 5b, 5c, and 5d are tightly covered with a cover 13 having a thickness of about 1 mm. This cover 13 is for protecting the smartphone 1 from scratches and impacts. A flat shaft 6 (inside of the broken line in the figure) having a rotation center shaft 6b perpendicular to the back surface is attached to the back surface 4 via the cover 13. A ring-shaped flat wheel 7 that rotates along the back surface 4 is fitted around the shaft 6. A retaining portion 6 a that prevents the wheel 7 from falling off the shaft 6 protrudes from the shaft 6 in the outer peripheral direction and covers the inner periphery of the wheel 7. A rod-shaped lever 8 is connected to a part of the outer periphery of the wheel 7 in a direction perpendicular to the rotation center shaft 6 b of the shaft 6. In this embodiment, the wheel 7 and the lever 8 are formed as a single piece from a single plastic plate. The distal end portion 8a of the lever 8 is wider than the intermediate portion 8b. The lever 8 extends from the back surface 4 in the direction of the side surface 5a and protrudes about 3 cm laterally from the side surface 5a. This smartphone 1 is used in this state. Portions other than the smartphone 1 and the cover 13 having this configuration are collectively referred to as a holder. *

The wheel 7 and the lever 8 connected thereto rotate around the axis 6. FIG. 2 shows a state in which the position is slightly rotated from the position shown in FIG. It rotates about 70 degrees, and the entire lever 8 is exactly along the back surface 4. And it retracts without protruding from any side. When the smartphone 1 is not used, it is stored in a pocket or bag in such a low bulk state that there is almost no protrusion. In this manner, the lever 8 can be rotated to protrude from the side surface 5a as shown in FIG. 1 or along the back surface 4 without protruding from any side surface as shown in FIG. *

FIG. 3 is a cross-sectional view taken along the line AA in FIG. The rotation mechanism of the wheel 7 will be described in detail with reference to FIG. Here, the smartphone 1 has a width of about 7 cm and a thickness of about 8 mm. A cover 13 is fixed to the back surface 4, and a flat shaft 6 having a diameter of about 2.5 cm and a height of 3 mm is bonded onto the cover 13. A ring-shaped flat wheel 7 having an outer diameter of about 5 cm, an inner diameter of about 2.7 cm, and a thickness of less than 2 mm is fitted around it. Further, a retaining portion 6 a having an outer diameter of about 4 cm and a thickness of 1 mm protrudes from the outer surface of the shaft 6 on the front side of the shaft 6. Since the wheel 7 is not joined to the cover 13, the shaft 6, or the retaining portion 6 a, the wheel 7 can freely rotate around the shaft 6 along the back surface 4. Since the retaining portion 6 a having a diameter larger than the inner diameter of the wheel 7 is covered on the upper side, the wheel 7 does not fall off the shaft 6. *

As can be seen from the above description, the total thickness of the holder is very thin, about 4 mm in total, so that even when it is attached to the back surface 4 of the smartphone 1, there is almost no obstacle during carrying. In addition, the wheel 7 which is a movable part and the lever 8 to which hand force is applied are hard plastics having a thickness of about 2 mm, so that they are not deformed by some force. *

FIG. 4 is a perspective view when the first embodiment of the portable electronic terminal holder of the present invention is used. It is the place which has the state of FIG. 1 with the right hand. Insert the finger so that the middle portion 8b of the protruding lever 8 is between the middle finger 33 and the ring finger 34 of the right hand, and the tip of the index finger 32, the middle finger 33, the ring finger 34 and the little finger 35 of the smartphone 1 through the cover 13 Touch the back 4 (not shown). The tip of the finger partially hits the shaft 6 or the retaining portion 6a (not shown), but since both the shaft 6 and the retaining portion 6a are thin, the finger is touched against the back surface 4 sensuously. Is the same as In this state, when the input unit 3 which is a screen on the front surface 2 of the smartphone 1 is pressed with the thumb 31, the input can be performed. Moreover, since the lever 8 is caught between the fingers, the smartphone 1 is unlikely to fall from the hand. *

The lever tip portion 8a has a maximum width of 30 mm, and is wider and thicker than the minimum width of 8 mm of the lever intermediate portion 8b. The lever tip 8 a protrudes from the side surface of the smartphone 1. The minimum width portion of the lever intermediate portion 8b also protrudes from the side surface 5a. This minimum width portion is positioned between the middle finger 33 and the ring finger 34. Then, since the distance between the middle finger 33 and the ring finger 34 is about 8 mm, even when the lever 8 is about to come out between the fingers, the lever tip portion 8a having a width of 30 mm is caught and hardly falls. *

The protruding dimension of the lever 8 is that the thickness of a finger such as a middle finger is about 2 cm for a general person and is sandwiched between the fingers. On the contrary, if it is long, it will be pinched | interposed reliably between fingers, but it becomes difficult to retract along the back surface 4, so that it is long. The protrusion length sufficient to make the invention of this application function is about 5 cm at the maximum, and even if it is longer than that, the effect of the invention is not further enhanced. *

The above description is for the case of holding the smartphone 1 with the right hand, but the same can be done with the left hand. Since the wheel 7 rotates to an arbitrary position and stays with static friction, the wheel 7 protrudes from the side surface 5b opposite to the side surface 5a used with the right hand and is fastened. Next, the same operation can be performed with the left hand if the contents described with the right hand are symmetric. At this time, when the rotation center shaft 6b of the shaft 6 is placed at the same distance from the two

side surfaces

5a and 5b that are the long sides of the smartphone 1 that are rectangular, the lever 6 is positioned on the center line of the smartphone 1. Since the amount of protrusion from the side of 8 can be made exactly the same on the left and right, it can be held with exactly the same feeling with the left and right hands.

Next, further application of the first embodiment will be described with reference to FIGS. 5 and 6. FIG. 5 is a perspective view of the back surface of the first embodiment of the portable electronic terminal holder of the present invention. In FIG. 5 and FIG. 6, what is common to the previous drawings is indicated by the same reference numeral. In FIG. 5, the lever 8 protrudes laterally from the side surface 5 d corresponding to the lower side of the smartphone 1. At this position, the lever 8 is fastened. FIG. 6 shows the lever 8 held by hand. Thus, in order to protrude the lever 8 from the side surface 5d, since the smartphone 1 is substantially rectangular, the position of the rotation center axis 6b is positioned close to one side of the

short side

5c and 5d and close to one side 5d. It is necessary. By shifting the position, the lever 8 can be protruded toward the side surface 5d, and conversely, when the lever 8 is rotated and brought to the side surface 5c, the distance to the side surface 5c is longer than the length. Therefore, as seen in FIG. 2, the lever 8 does not protrude from any side surface, and there is no protrusion from the side surface along the back surface, which is convenient for storage. *

FIG. 6 is a perspective view when the first embodiment of the portable electronic terminal holder of the present invention is used. The above-mentioned holding method in FIG. 4 is the case where the portable electronic terminal is held in the portrait, but in this FIG. 6, it is the holding method when it is held in the landscape. Insert the finger so that the middle portion 8b of the protruding lever 8 is between the index finger 32 and the middle finger 33 of the right hand, and the tip of the index finger 32, the middle finger 33, the ring finger 34, and the little finger 35 through the case 13 through the back of the smartphone 1 4 (not shown). The fingertip partially hits the retaining portion 6a (not shown). In this state, when the input unit 3 which is a screen on the front surface 2 of the smartphone 1 is pressed with the thumb 31, the input can be performed. Since the place of thumb input differs depending on the individual hand holding, the lever 8 may be inserted between the middle finger 33 and the ring finger 34 according to each individual's preference. *

As described above, the lever 8 rotates together with the wheel 7 and is fixed at an arbitrary angle. Therefore, the lever 8 protrudes from the side surface 5a and the side surface 5b which are the long sides of the substantially rectangular smartphone 1, and is also substantially rectangular. It can also protrude from the side surface 5d which is the short side of the shaped smartphone 1. That is, the lever 8 can protrude from the side surfaces in the three directions. Moreover, it can also be set as the position which does not protrude from any side surface. Because of this structure, you can hold it with your right hand, hold it with your left hand, hold it in portrait, hold it in landscape, and store it compactly it can. *

In this embodiment, the wheel 7 and the lever 8 are formed as a single piece of plastic plate, but this configuration has advantages. The lever 8 is applied with force by hitting a finger. The stress acts to make the lever 8 bend and the wheel 7 to fall off. At this time, in the present embodiment, the wheel 7 and the lever 8 are integrally formed, so that the concentration of stress is small, and the stress is distributed over the entire lever 8 and the wheel 7 to increase durability.

A second embodiment will be described with reference to FIGS. FIG. 7 is a perspective view of the back surface of the second embodiment of the portable electronic terminal holder of the present invention. In FIG. 7, the same components as those in the previous drawings are denoted by the same reference numerals. A smartphone 1 that is a portable electronic terminal has a rectangular flat plate shape as a whole, and includes a front surface 2 (not shown) having a display / input unit, a back surface 4 on the opposite side, and the front surface 2 and the back surface. Have four

side surfaces

5a, 5b, 5c and 5d. A flat shaft 6 (inside of the broken line in the figure) having a rotation center shaft 6 b perpendicular to the back surface is attached to the back surface 4 via a cover 13. A ring-shaped flat wheel 7 that rotates along the back surface 4 is fitted around the shaft 6. A retaining portion 6 a that prevents the wheel 7 attached to the shaft 6 from falling off the shaft 6 protrudes from the shaft 6 in the outer peripheral direction and covers the inner periphery of the wheel 7. A thin flat plate-shaped flap 11 is placed on the retaining portion 6a, and a rod-shaped lever 8 is formed in a direction perpendicular to the rotation center shaft 6b of the shaft 6 continuously from the flap 11. The flap 11 and the lever 8 are made of a slightly bent plastic plate as an integral part. The lever 8 has a narrow intermediate portion 8b and a wide lever tip 8a. The lever tip 8a protrudes about 4 cm from the side surface 5a. *

FIG. 8 is a perspective view of the back surface of the portable electronic terminal holder according to the second embodiment of the present invention when not in use. The flap 11 and the lever 8 are connected to the wheel 7 and rotate in the same manner as the wheel 7 rotates. When the wheel 7 is rotated from the state shown in FIG. 7, the lever 8 is rotated accordingly. In FIG. 8, the lever 8 is retracted without protruding from any side surface and is almost exactly along the back surface 4. When the smartphone 1 is not used, the smartphone 1 is stored in a pocket or bag without being bulky with almost no protrusion. *

FIG. 9 is an arrow diagram of the second embodiment of the portable electronic terminal holder of the present invention, and is a view of the smartphone 1 and the holder of FIG. 7 as seen from the direction of arrow B in FIG. On the back surface 4 side of the smartphone 1, there is a wheel 7, which is prevented from being removed from the shaft 6 (not shown) by a retaining portion 6a. A part of the wheel 7 has a wheel extending portion 7a, and one end of a hinge 12 that moves like a hinge is attached to the end of the wheel extending portion 7a. The other end of the hinge 12 is attached to the lever 8. The lever 8 and the flap 11 are formed by partially deforming a single plate-like plastic, and the thickness of the plate is about 2 mm. *

FIG. 10 is an arrow diagram when the second embodiment of the portable electronic terminal holder of the present invention is used. FIG. 9 shows that the state shown in FIG. 9 held with the right hand is viewed from the direction of arrow B in FIG. The hand holding method is exactly the same as that shown in FIG. 4 of the first embodiment. Insert the finger so that the middle part 8b of the protruding lever 8 is between the middle finger 33 and the ring finger 34 of the right hand, and the tip of the index finger 32, the middle finger 33, the ring finger 34, and the little finger 35 are placed on the back surface 4 of the smartphone 1 or above It is applied to the shaft 6, the retaining part 6 a or the flap 11. In this state, it is possible to input by pressing the input unit 3 (not shown) on the front surface 2 of the smartphone 1 with the thumb 31. The lever 8 is caught between the fingers, and the lever tip 8a is wider and thicker than the lever middle portion 8b, so that the lever 8 is also caught when trying to come out between the fingers and is hard to fall. It has become. The lever 8 and the flap 11 are only joined at one point of the hinge 12 to the smartphone side. However, when it is held as shown in FIG. 10, the weight of the smartphone 1 is applied to the flap 11 from the retaining portion 6a, and the flap 11 is supported by a finger, so that the flap 11 and the retaining portion 6a are pressed against each other. Fixed by force. After all, the holding state of the lever described in FIG. 4 is exactly the same, and the holding is stable. Also, if you change the side of the lever, you can hold it with your left hand or landscape. This is also the same as in the first embodiment. *

Although the operational effects described so far are substantially the same as those of the first embodiment, features unique to the second embodiment will be described below with reference to FIG. FIG. 11 is a perspective view of a second embodiment of the portable electronic terminal holder of the present invention. In FIG. 11, the same elements as those in the previous drawings are denoted by the same reference numerals. As described above, the integrated body of the lever 8 and the flap 11 is joined by the wheel 7 and the hinge 12. The lever 8 and the flap 11 can rotate around this hinge. In the state shown in FIG. 11, the lever 8 is rotated 90 degrees around the hinge 12 from the state shown in FIG. The flap 11 is lifted from the retaining portion 6a, and the lever 8 is bent toward the front surface 2 and hits the side surface 5a. *

FIG. 12 is an arrow diagram of the second embodiment of the portable electronic terminal holder of the present invention. 12 is a view seen from the direction of arrow C in FIG. The flap 11 and the lever 8 are rotated 90 degrees around the hinge 12 and are bent at a right angle to the front surface 2 side so as to stand vertically. The rotation stops when the lever 8 hits the cover 13 covering the side surface 5a. The front surface 2 of the smartphone 1 is facing downward (toward the ground). The tip 8a of the lever 8 protrudes downward from the front surface 2 of the smartphone 1 by about 3 cm. *

FIG. 13: is an arrow figure at the time of use of 2nd Embodiment of the portable electronic terminal holder of this invention. It is the figure which looked at the state which hold | maintained the smart phone 1 of the state of FIG. 12 in the right hand from the arrow C direction of FIG. Hold the tip 8a of the lever 8 slightly into the palm 36 of the right hand so that the index finger 32, the middle finger 33, and the ring finger 34 (not shown) are hooked on the end of the flap 11 and gripped lightly. Hold on to. *

By holding in this way, the smartphone 1 can be stably held with the front surface 2 facing downward. Due to the weight of the smartphone 1, the smartphone 1 is rotated counterclockwise around the hinge 12. The force is applied to the side surface 5a and is stopped by being received by the lever 8, and the side surface 5a and the lever 8 are fixed. Further, since the stress is applied to the lever tip 8a and is received by the palm, the holding is stable. *

At this time, since the thumb 31 can be freely moved as it is involved in holding, the thumb 31 can push a desired position of the input unit 3 (not shown) on the front surface 2. That is, it is possible to input easily with the thumb of one hand with the smartphone 1 facing down on the front surface 2. In other words, the smartphone can be freely operated with one hand in a posture of lying on its back. *

Since the lever 8 is applied to the palm 36, if the length protruding from the front surface 2 is too long, the thumb cannot reach the front surface 2. However, if the protruding length is small, the root of the thumb 31 hits the input unit 3 and cannot be input correctly. Depending on the size of the hand, a suitable protrusion length is about 2 cm to 7 cm. *

In this embodiment, the lever 8 can be flexible. The advantages in that case will be described with reference to FIG. 14 is a view seen from the direction of arrow C in FIG. 11 as in FIG. If the lever 8 is bent, when the hand is pressed with a force, the palm 36 strongly presses the tip 8a, and the lever 8 is bent and curved. Therefore, the thumb 31 reaches the far side of the front surface 2 and the part far from the palm 36 can be input. Thus, thumb input can be easily performed over a wide range of the input unit 3 by variously changing the degree of curvature of the flexible lever. *

In the above-described series of operations, the middle finger 33 and the ring finger 34 sandwich the lever intermediate portion 8b. However, it is not necessary to apply force to both fingers to sandwich the lever intermediate portion 8b from both sides. It is sufficient to place the lever intermediate part 8b between both fingers. Because the lever tip 8a is in contact with the backs of both fingers, the lever 8 does not fall out and the portable electronic terminal 1 does not fall from the hand. *

The retaining portion is intended to prevent the wheel from falling off the shaft, and therefore does not need to cover the entire wheel. A mechanism that only presses the wheel at several locations locally may be used. Also, a mechanism for preventing dropout may be provided in the middle part of the shaft. Moreover, although the axis | shaft in said each embodiment showed the example whose outer periphery is a perfect circumference, this invention is not restricted to the axis | shaft of a perfect circumference. If it has the outer periphery which prescribes | regulates the center axis | shaft of the rotation track | orbit of a wheel inside a ring-shaped wheel, the effect of this invention will not be impaired. Similarly, although the wheel in each of the above-described embodiments has shown an example in which the inner periphery is a complete circle, the present invention is not limited to a wheel having a complete circle. Anything that rotates can be used.

In addition, although the axis | shaft in said each embodiment showed the example attached to the back surface of the cover which protects a smart phone, this invention is not restricted to the structure which attaches a shaft to a cover. A shaft may be directly attached to the back of the smartphone body. *

In addition, although each said embodiment described only about the smart phone, this invention is not restricted to a smart phone. Any portable electronic terminal having a substantially rectangular flat plate shape and having a front surface 2 with an input unit, a back surface on the opposite side, and a side surface between the front surface 2 and the back surface is applicable. For example, the present invention can be applied to a tablet PC, and can also be applied to an ordinary button input type mobile phone.

INDUSTRIAL APPLICABILITY The portable electronic terminal holder according to the present invention is useful because simple and easy means can ensure the holding of the portable electronic terminal while allowing a variety of input with good operability and the operability with one hand alone is increased. .
