[Slide, T-turn, Tilt operation]
First, the slide, T-turn, and tilt operations will be described.
The first hinge unit 1 has a slide rail 11.
The second hinge part 2 has a slide rail receiver 21, a T-turn shaft 22, and a T-turn protrusion 23. The slide rail receiver 21 is slidably connected to the slide rail 11 of the first hinge unit 1 so that the first hinge unit 1 and the second hinge unit 2 slide relative to each other (FIGS. 2A and 2B). The T-turn shaft 22 is a central axis for making a T-turn with the third hinge portion 3. The T-turn protrusion 23 is disposed outside the T-turn shaft 22 and moves in an arc along with the T-turn.

  The third hinge portion 3 includes a T-turn bearing 31, a T-turn groove 32, a tilt regulating lever 33, a lever cover 34, and a tilt connecting portion 35. The T-turn bearing 31 is a receiving part of the T-turn shaft 22 of the second hinge part 2, and the second hinge part 2 and the third hinge part 3 make a T-turn to each other (FIG. 3 (C1), FIG. 4 (C2). )). The T-turn groove 32 is formed in an arc shape and serves as a guide for the T-turn protrusion 23 of the second hinge portion 2. The tilt restriction lever 33 and the lever cover 34 are component parts for tilt restriction, and will be described in detail later in [Tilt restriction]. The tilt connecting part 35 is a connecting part for tilting with the fourth hinge part 4.

  The fourth hinge part 4 is rotatably connected to the tilt connecting part 35 of the third hinge part 3 for tilting on the tilt rotation shaft 41, and the third hinge part 3 and the fourth hinge part 4 are mutually connected. Tilt (FIG. 5D).

  Due to the structure of the hinge 7 described above, the first hinge portion 1 and the second hinge portion 2 slide relative to each other, the second hinge portion 2 and the third hinge portion 3 make a T-turn to each other, and the third hinge portion 3 and the second hinge portion 3 The four hinge portions 4 tilt with respect to each other. The first hinge portion 1 is attached and fixed to the fixing portion 82 of the first housing 8, and the fourth hinge portion 4 is attached and fixed to the fixing portion 92 of the second housing 9. Thereby, the slide, T-turn, and tilt shown in FIGS. 2, 3, 4, and 5 are performed.

[Tilt regulation]
Next, tilt regulation will be described. The tilt regulating lever 33 of the third hinge portion 3 is housed inside the lever cover 34 so as to be movable, and is housed inside the lever cover 34 and is urged toward the T-turn groove 32 by a spring (not shown).

  During the slide from FIG. 2 (A) slide close to (B) slide open, the T-turn protrusion 23 of the second hinge portion 2 is always in contact with the tilt restricting lever 33 to bias the spring (not shown). On the other hand, the tilt regulating lever 33 is pressed against the T-turn groove 32 in the opposite direction. As a result, as shown by a circular dotted line, the tilt restriction lever 33 is fitted into the tilt restriction lever receiving portion 93 of the second housing 9, and the main surface of the first housing 8 is the main surface of the second housing 9. Tilt tilting with respect to the surface is regulated.

  FIG. 3 (C1) is immediately after the start of the T-turn. As the T-turn starts, the T-turn protrusion 23 of the second hinge portion 2 rotates in an arc along the T-turn groove 32 of the third hinge portion 3. As a result, the T-turn protrusion 23 comes out of contact with the tilt regulating lever 33, and the tilt regulating lever 33 is pushed toward the T-turn groove 32 by a biasing force of a spring (not shown). Then, as shown by a circular dotted line, the tilt restriction lever 33 is disengaged from the tilt restriction lever receiving portion 93 of the second housing 9, and the main surface of the first housing 8 is the main surface of the second housing 9. Tilt tilting with respect to the surface is allowed.

  FIG. 4 (C2) is when the T-turn is completed. The T-turn protrusion 23 of the second hinge part 2 further rotates in an arc along the T-turn groove 32 of the third hinge part 3 and moves to the end of the T-turn groove 32. Even in this state, similarly, the contact between the T-turn protrusion 23 and the tilt regulating lever 33 is disengaged, so that the tilt regulating lever 33 is the tilt regulating lever receiving portion of the second housing 9 as shown by the circular dotted line. 93 is allowed to be tilted so that the main surface of the first housing 8 is tilted with respect to the main surface of the second housing 9.

  FIG. 5D shows a state in which the user has tilted from the tilt-permitted state at the completion of the T-turn in FIG. 4C2. The main surface of the first housing 8 is tilted with respect to the main surface of the second housing 9.

  As described above, according to the first embodiment of the present invention, the tilt can be restricted during the slide, and the tilt is permitted after the start of the T-turn.

  The second embodiment is an embodiment in which the tilt restriction range is increased as compared with the first embodiment. The present invention relates to a structure that regulates tilt in the sliding state shown in FIGS. 1A and 1B and the state until the middle of the T-turn shown in FIG.

  6A and 6B are structural diagrams of the electronic device 100 and the hinge 7 according to the second embodiment of the present invention. FIG. 6B shows a sliding open state, and FIG. 6C1 shows a T-turn halfway state. The difference from the first embodiment is that the arrangement of the tilt restriction lever 33 of the third hinge part 3 is arranged on the side surface side, and the arrangement of the tilt restriction lever receiving part 93 of the second housing 9 is also arranged on the side surface side. In addition, a new intermediate lever 36 is provided and disposed between the T-turn groove 32 and the tilt regulating lever 33. Others are the same as Example 1, and a difference is mainly demonstrated below.

  Although there are a cover lever that covers the tilt regulating lever 33 and a spring in the cover lever, it is the same as in the first embodiment and is not shown. The tilt restriction lever receiving portion 93 has a hole into which the tilt restriction lever 33 is fitted.

  The intermediate lever 36 has a substantially arc shape, has a fulcrum 36a at one end and an end 36b at the other end, and is movable on the end 36b side around the fulcrum 36a. The intermediate lever 36 has an arcuate side facing the T-turn groove 32, and the T-turn protrusion 23 abuts on this portion, and the T-turn protrusion 23 slides along with the T-turn.

  At the start of the T-turn, as shown in (B), the T-turn protrusion 23 comes into contact with the end 36b side of the intermediate lever 36, and the end 36b comes into contact with the tilt regulating lever 33, so that the tilt regulating lever 33 Is fitted to the tilt regulating lever receiving portion 93 to regulate the tilt.

  The T-turn protrusion 23 is in contact with the arc-shaped portion of the intermediate lever 36 until the T-turn protrusion 23 reaches the fulcrum 36a of the intermediate lever 36 until the T-turn protrusion 23 reaches the fulcrum 36a of the intermediate lever 36. In the same manner, the tilt is restricted without moving.

  When the T-turn further advances and the T-turn protrusion 23 exceeds the fulcrum 36a of the intermediate lever 36, as shown in (C1), the T-turn protrusion 23 comes out of contact with the arc-shaped portion of the intermediate lever 36, The end 36b is free, and the tilt regulating lever 33 is moved away from the tilt regulating lever receiving portion 93 (an arrow in the figure) by the urging force of a spring in a cover lever (not shown) to be disengaged. The tilt is allowed.

  The tilt restricting lever 33 is moved in the direction of the arrow in the figure by the urging force of a spring in a cover lever (not shown) to enter a tilt permitting state. A push button is provided on the side of the tilt restricting lever 33 further. Then, the tilt may be permitted by pressing in the direction of the arrow in the figure by a user operation.

  According to the second embodiment of the present invention, the tilt can be restricted during the slide and the middle of the T-turn.

[Modification]
In both the first and second embodiments, the hinge 7 has a structure capable of sliding, T-turning, and tilting. As a modification thereof, the hinge 7 has a structure in which the first hinge portion 1 is deleted and the second hinge portion 2, the third hinge portion 3, and the fourth hinge portion 4 are provided, and the first housing 8 is the second hinge. The structure may be fixed to the portion 2 and only have a T-turn and a tilt.

[Modification]
Further, in both the first and second embodiments, the tilt restriction lever receiving portion 93 that fits the tilt restriction lever 33 of the third hinge portion 3 is provided in the second housing 9 that is different from the hinge 7. As a modification thereof, the tilt regulating lever receiving portion 93 of the second housing 9 is deleted. The fourth hinge portion 4 has a structure that extends further from the tilt rotation shaft 41 in the direction of the tilt restricting lever receiving portion 93. The extending portion is provided with an equivalent to the tilt restricting lever receiving portion 93, and the extending destination is the second housing. It is good also as a structure fixed to the body 9. FIG. According to this modification, since the tilt restricting structure is completed with the hinge 7 alone, the housing 7 only needs to be attached and fixed to the hinge.

  The third embodiment relates to a structure that regulates the T-turn during tilting when the T-turn operation is performed by the user in the tilt state of FIG. In the third embodiment, a T-turn regulating mechanism is further added to the first or second embodiment, and the T-turn regulating mechanism will be mainly described.

FIG. 7 is a structural diagram of the electronic device 100 and the hinge 7 according to the third embodiment of the present invention. FIG. 7D is a T-turn restricted state during tilting, and FIG. Indicates turn permission status.
FIG. 8 is a perspective view of the third hinge portion 3 of the hinge 7 according to the third embodiment of the present invention. Hereinafter, both drawings will be described.

  The second hinge part 2 has a T-turn regulating hole 24. As shown in FIG. 8, the third hinge portion 3 has a T-turn regulating lever 37. The T-turn regulating lever 37 has an end portion 37b and an end portion 37c around the fulcrum 37a, and further includes a spring 37d.

  The second housing 9 has a T-turn allowable protrusion 94 (contact portion). With the tilt of the first housing 8 and the second housing 9, the T-turn allowable protrusion 94 abuts on the end portion 37 b of the T-turn regulating lever 37.

  In the tilt state of FIG. 7D, the T-turn allowable projection 94 and the end portion 37b are separated from each other, and the end portion 37c is separated from the second hinge by the biasing force of the spring 37d (FIG. 8) of the T-turn regulating lever 37. It is pushed out in the direction of the T-turn restricting hole 24 of the part 2 to be fitted with the T-turn restricting hole 24. Thereby, the 2nd hinge part 2 and the 3rd hinge part 3 will be in a T-turn regulation state, and cannot perform a T-turn.

  In the non-tilt state of FIG. 7C, the T-turn allowance protrusion 94 abuts on the end portion 37b, and the end portion 37c is disengaged from the T-turn regulating hole 24 of the second hinge portion 2, and the fitting is disengaged. It becomes a state. Thereby, the 2nd hinge part 2 and the 3rd hinge part 3 will be in a T-turn permission state, and can make a T-turn.

[Modification]
It should be noted that the T-turn allowable projection 94 of the second housing 9 and the end portion 37b of the T-turn regulating lever 37 need only be in a non-tilted state, and the projection may be provided on either side. That is, the T-turn allowable protrusion 94 of the second housing 9 may be deleted, and a protrusion may be provided at the end portion 37 b of the T-turn regulating lever 37. In addition, the structure is not limited to the protrusion, and any structure may be used as long as the structure makes contact in a non-tilt state and the contact is released in the tilt state.

  According to the third embodiment of the present invention, it is possible to regulate the T-turn during tilting and prevent the casings from colliding with each other.

  Note that the electronic device of the present invention can be applied to a mobile phone, a PHS, and other devices having both a T-turn operation and a tilt operation.
