Description

Gripping aid for portable information terminal

The present invention relates to a grip assisting tool that assists gripping for a portable information terminal.

Information terminals that are carried and used, such as tablet computers and multifunctional mobile phones (smartphones), are becoming popular. These portable information terminals have a touch panel type operation display screen for operating the terminal and displaying information. In recent years, an increase in the size of the operation display screen has been demanded, and accordingly, the size of the portable information terminal itself has been increasing. At the same time, a member / mechanism for assisting the holding / operation by hand when using the portable information terminal has been proposed.

For example, in Patent Document 1, the bulgeable portion is raised to form a tubular space, and the user holds the cover by placing a finger in the space so that the palm approaches the center of the device (portable information terminal). A mechanism for assisting the holding of the apparatus is proposed. With this mechanism, the user's hand can stably hold the main surface of the touch panel device without touching it, so that the human machine interface (screen) on the main surface can use a larger area. Yes.

Patent Document 2 proposes a cover for a multi-function mobile phone having a non-slip member that can be projected or flattened. This mechanism has the disadvantage that in a multifunctional mobile phone that is becoming larger, it is held only with one hand and needs to be held with one hand as it is operated with the other hand, but it is difficult to hold and slips easily from the hand. It has been proposed to overcome.

The support member 22 has a fifth end E5 that is one end in the short-side direction and a sixth end E6 that is the other end. The fifth end E5 of the support member 22 is rotatably supported by the main member 21. With the above-described configuration, the second member has a state in which the main member 21 and the support member 22 are plate-like as a whole (the state shown in FIGS. And can be rotated and opened (the state shown in FIG. 4).

In the latter state (the state shown in FIG. 4), the support member 22 can function as a member that supports the portable information terminal 200. For example, when the portable information terminal 200 is placed on a plane with the long side 210 or the long side 220 facing down, the sixth end E6 of the support member 22 is in contact with the plane, and the operation display screen 250 of the portable information terminal 200 is vertical.

With this structure, the third end E 3 of the second member 20 is rotatably supported by the second end E 2 of the first member 10, and the second member 20 rotates with respect to the first member 10. It is possible.

The fourth end E4 is an end (long side) of the second member 20 on the + X side. (As described above, the fourth end E4 of the second member 20 is also the sixth end of the support member 22).

The second member 20 has a lever 23 and a pin 24. The lever 23 is a rod-shaped member extending in the X direction. The levers 23 are arranged one by one at both ends in the Y direction of the second member 20 (main member 21) in a cantilever state where the end on the −X side is supported.

The pin 24 is a cylindrical member extending along the Y direction. The pin 24 is disposed at the end of the lever 23 on the + X side. With the structure described above, the pin 24 is disposed in the vicinity of the fourth end E4 of the second member 20.

The lever 23 can be bent by elastic deformation in the Y direction. Thereby, the pin 24 (and its tip 24a) is movable in the Y direction.

The pin 24 is inserted into the groove 4 of the main body 1. Since the groove 4 is formed to extend in the X direction, the pin of the fourth end E4 can move in the groove 4 in the X direction. With this structure, the fourth end E 4 is supported by the main body 1 and can move in parallel with the portable information terminal 200.

<First state and second state>
The first member 10 and the second member 20 take a first state in which the posture is along the portable information terminal 200 and a second state in which the posture is raised from the portable information terminal.

FIG. 1 shows the first state. In the first state, the first member 10 and the second member 20 take a posture along the portable information terminal 200, that is, a posture parallel to the main body 1. At this time, as described above, the surfaces on the + Z side of the main body 1, the first member 10, and the second member 20 coincide with each other, and these surfaces form a substantially flat surface.

The second end E2 of the first member 10 and the third end E3 of the second member 20 are located near the center of the main body 1 in the X direction. The fourth end E4 of the second member 20 is located near the end of the main body 1 in the + X direction, that is, near the end of the hole 3 in the + X direction. The pin 24 is located near the end of the groove 4 in the + X direction.

FIG. 2 shows the second state. In the second state, the first member 10 and the second member 20 are raised from the portable information terminal 200, and are protrusions having a triangular shape when viewed from the −Y direction.

The first end E1 of the first member 10 is located near the end of the main body 1 in the −X direction, that is, near the end of the hole 3 in the −X direction, as in the first state. The second end portion E2 of the first member 10 and the third end portion E3 of the second member 20 move from the position in the first state in the −X direction to the center line CL2 in the width direction of the portable information terminal 200. On the other hand, it is located on the -X side. The fourth end E4 of the second member 20 moves in the −X direction from the position in the first state, and is positioned on the + X side with respect to the center line CL2 in the width direction of the portable information terminal 200. The pin 24 is located near the end of the groove 4 in the −X direction.

At this time, the fourth end E4 of the second member 20 is located on the + X side with respect to the center line CL2 in the width direction of the portable information terminal 200 (see FIG. 2). On the other hand, the first end E1 of the first member 10 does not move, but is positioned at the −X side end of the hole 3 of the main body 1, that is, in the vicinity of the long side 210 of the portable information terminal 200. Accordingly, the first end E1 is located on the −X side with respect to the center line CL2 (see FIG. 1). As described above, in the cover 100, the first end E1 of the first member 10 and the fourth end E4 of the second member 20 in the second state are on the center line CL2 parallel to the long side 210 of the portable information terminal. Located on different sides.

<Changes in groove shape and pin position>
5, 6, and 7, the shape of the groove 4 and the pin 24 in the groove 4 when the postures of the first member 10 and the second member 20 change from the first state to the second state are described. A change in position and deformation of the lever 23 will be described.

As shown in FIG. 2, FIG. 5, etc., the groove 4 has a protrusion 4a and an inclined portion 4b. The protrusion 4 a is a part formed by protruding the bottom of the groove 4 in the Y direction, and is a part protruding from the bottom surface of the groove 4 toward the second member 20. The protrusion 4 a is formed at an intermediate position in the X direction in the groove 4. The inclined portion 4b is an inclined surface that connects the bottom surface of the groove 4 and the tip of the protrusion 4a. The inclined portion 4b is formed on both sides of the protrusion 4a in the X direction and adjacent to the protrusion 4a.

FIG. 5 shows the shape of the groove 4 on the + Y side of the main body 1. The groove 4 is dug in the + Y direction from the surface facing the second member 20. The depth of the groove 4 is deep at the + X side and −X side ends, and is shallow near the center due to the presence of the protrusion 4a.

In FIG. 5, the first member 10 and the second member 20 are in the first state (a state along the portable information terminal 200). At this time, the pin 24 is positioned near the end in the + X direction in the groove 4, that is, on the + X side of the protrusion 4a and the inclined portion 4b.

When changing from the first state to the second state, the fourth end E4 of the second member 20 moves in the -X direction, and the pin 24 moves in the -X direction along with this movement. At that time, the pin 24 comes into contact with the inclined portion 4b and the protrusion 4a and receives resistance from the inclined portion 4b and the protrusion 4a. The pin 24 advances along the inclined portion 4b while resisting this resistance force. At this time, the pin 24 is exerted in the −Y direction. This force causes the lever 23 to bend in the −Y direction. Due to the bending of the lever 23, the pin 24 (and its tip 24a) moves in the -Y direction. In this way, as shown in FIG. 6, the pin 24 can be positioned above the protrusion 4a (−Y side) in the groove 4.

Further, when the fourth end E4 of the second member 20 moves in the −X direction, the pin 24 moves over the protrusion 4a and advances along the inclined portion 4b. Then, the pin 24 reaches the end of the groove 4 on the −X side (the state shown in FIG. 7), and the first member 10 and the second member 20 are in the second state. At this time, the bending of the lever 23 decreases and becomes almost zero, and the pin 24 (and its tip 24a) moves in the + Y direction.

That is, when the force that the pin 24 can get over the protrusion 4a acts on the fourth end E4 against the resistance force received from the inclined portion 4b and the protrusion 4a, the change from the first state to the second state occurs. If the force for moving the fourth end E4 in the −X direction is small, the state does not change and the first state is maintained. That is, the first state is held by the protrusion 4a and the inclined portion 4b.

The reverse process proceeds when changing from the second state to the first state. That is, when the fourth end E4 of the second member 20 moves in the + X direction, the pin 24 moves in the + X direction accordingly. At that time, the pin 24 comes into contact with the inclined portion 4b and the protrusion 4a and receives resistance from the inclined portion 4b and the protrusion 4a. The pin 24 advances along the inclined portion 4b while resisting this resistance force. At this time, the pin 24 is exerted in the −Y direction. This force causes the lever 23 to bend in the −Y direction. Due to the bending of the lever 23, the pin 24 (and its tip 24a) moves in the -Y direction. In this way, as shown in FIG. 6, the pin 24 can be positioned above the protrusion 4a (−Y side) in the groove 4.

Further, when the fourth end E4 of the second member 20 moves in the + X direction, the pin 24 gets over the protrusion 4a and advances along the inclined portion 4b. Then, the pin 24 reaches the end on the + X side of the groove 4 (state in FIG. 5), and the first member 10 and the second member 20 are in the first state. At this time, the bending of the lever 23 decreases and becomes almost zero, and the pin 24 (and its tip 24a) moves in the + Y direction.

That is, when the force that the pin 24 can get over the protrusion 4a acts on the fourth end E4 against the resistance force received from the inclined portion 4b and the protrusion 4a, the change from the second state to the first state occurs. If the force for moving the fourth end E4 in the + X direction is small, the state does not change and the second state is maintained. That is, the second state is maintained by the protrusion 4a and the inclined portion 4b.

<Proximity site of second member>
With reference to FIG. 8, FIG. 9, and FIG. 10, when the shape of the proximity portion 25 of the second member 20 and the posture of the first member 10 and the second member 20 change from the first state to the second state, The operation of the proximity portion 25 will be described.

As shown in FIG. 8, the support member 22 of the second member 20 has a proximity portion 25 formed therein. The proximity portion 25 is a portion that is closer to the portable information terminal side than the fourth end on the surface facing the portable information terminal 200 when the main body 1 is attached to the portable information terminal 200. The proximity part 25 is located between the third end E3 and the fourth end E4. Specifically, as shown in FIG. 8, the proximity portion 25 is a portion that protrudes from the support member 22 of the second member 20 in the −Z direction from the fourth end E4 (sixth end E6), This is an edge-shaped part extending in the Y direction.

Since the proximity portion 25 protrudes in the −Z direction from the fourth end portion E4, when a force in the −Z direction acts on the fourth end portion E4, the proximity portion 25 comes into contact with the portable information terminal 200 and becomes a fulcrum, A force in the + Z direction acts on the third end E3. In other words, when a force in the −Z direction is applied to the fourth end E4, a moment of force with the proximity portion 25 as a fulcrum is generated, and a force in the + Z direction acts on the third end E3. That is, when the fourth end E4 is pushed toward the portable information terminal 200, the second member 20 rotates around the proximity portion 25 and the third end E3 is lifted away from the portable information terminal 200.

When the third end E3 is lifted, the second end of the first member 10 connected to the third end E3 is also lifted away from the portable information terminal 200. Then, the fourth end E4 comes into contact with the portable information terminal 200 to be in the state of FIG.

9, when a force in the −X direction is applied to the second member 20, the second member 20 moves in the −X direction while the third end E3 and the second end E2 move in the + Z direction. To do. Then, the second member 20 moves to the −X direction end of the movement region (that is, the pin 24 moves to the −X direction end of the groove 4), and the second state (the state of FIG. 10) is obtained.

From the second state shown in FIG. 10, when a force is applied to the second end E2 and the third end E3 in the −Z direction, the first member 10 rotates and rotates around the first end E1. Then, the second end E2 and the third end E3 move in the −Z direction. Then, the fourth end E4 of the second member 20 moves in the + X direction along the portable information terminal 200, and the second member 20 moves in the −Z direction and the + X direction while rotating around the third end E3. .
