A computer, which is an example of the electronic device according to the first embodiment, will be described in detail with reference to the drawings.

As shown in FIGS. 1 to 3, the computer 22 of the first embodiment has a housing 24. The housing 24 is a rectangular parallelepiped box-shaped member in the example shown in FIGS.

Inside the housing 24, a board on which a processor, a control circuit, a main storage device, etc. are mounted, an auxiliary storage device, a connection terminal, etc. are accommodated. An input/output device such as a display, a keyboard and a mouse can be connected to the connection terminal. Furthermore, the structure may be such that a terminal for a network is provided and the terminal can be connected to the network.

In the housing 24, the front surface 24F has a rectangular shape and is provided with, for example, a connection terminal. The housing 24 can be placed on the installation surface SF (see FIG. 3) such that the front surface 24F is oriented vertically, so-called vertical placement. For example, FIG. 1 shows a state in which the housing 24 is placed vertically. On the other hand, FIGS. 2 and 3 show a state in which the housing 24 is tilted in the width direction (direction of arrow W) from the vertically placed state.

Hereinafter, the vertical direction, the width direction, and the depth direction of the housing 24 mean the vertical direction, the width direction, and the depth direction when the housing 24 is placed vertically, and in the drawings, the arrow U, the arrow W, and the arrow W, respectively. This is indicated by arrow D. In FIGS. 2 and 3, since the housing 24 is inclined, the direction indicated by the arrow W is also in a state of forming a predetermined angle (not parallel) with the installation surface SF.

When the housing 24 is placed vertically, when viewed from the front surface 24F side in the arrow A1 direction, the two surfaces located laterally, that is, on both sides in the width direction (arrow W direction) are side surfaces 24S.

The housing 24 is provided with auxiliary legs 26. The auxiliary leg 26 is an example of a protruding member. In the present embodiment, two auxiliary legs 26 are provided per one side surface 24S at a distance from each other in the depth direction (direction of arrow D), and four casings 24 as a whole. As will be described later, the auxiliary leg 26 functions as an auxiliary so as to support a part of the load of the housing 24 and suppress the tilting of the housing 24 when the housing 24 is tilted.

A rotary shaft 28 is provided above the auxiliary leg 26. The auxiliary leg 26 is attached to the housing 24 so as to be rotatable about a rotation shaft 28.

As shown in FIG. 2, the housing 24 is provided with a base 29 extending in the vertical direction. The base 29 is a substantially U-shaped member whose horizontal cross section is open to the side surface 24S. The inside of the base 29 is a housing recess 30 that houses the auxiliary leg 26. The auxiliary leg 26 moves between the storage position SP shown in FIG. 1 and the projecting position TP shown in FIGS. 2 and 3 by the rotation around the rotation shaft 28 and the movement in the vertical direction.

The auxiliary leg 26 is in a so-called flush state in which the outer surface 26G of the auxiliary leg 26 is located on the same plane as the side surface 24S of the housing 24 at the storage position SP. On the other hand, at the protruding position TP, the lower end 26B side of the auxiliary leg 26 projects from the side surface 24S of the housing 24.

As shown in FIGS. 4 and 5, the rotating shaft 28 has a columnar shaft body 32, and a pair of rectangular parallelepiped slide pieces 34 provided on both sides of the shaft body 32 in the longitudinal direction. have.

A pair of slide grooves 36 for holding the slide pieces 34 slidably in the vertical direction are formed on both sides of the housing recess 30 in the housing 24. The slide groove 36 is an example of a slide member.

In the state where each of the slide pieces 34 is held in the corresponding slide groove 36, the longitudinal direction of the shaft body 32 matches the depth direction of the housing 24 (the direction of arrow D in FIGS. 1 and 2 ). Then, in this state, the slide piece 34 slides in the vertical direction, so that the shaft body 32 also slides in the vertical direction. The vertical slide range of the shaft body 32 is limited to the range in which the slide piece 34 can slide within the slide groove 36.

As shown in FIGS. 2 to 4, a link 38 is bridged between the auxiliary leg 26 and the housing 24. A leaf spring 40 is arranged between the housing 24 and the link 38. The leaf spring 40 is an example of a first biasing member.

The leaf spring 40 urges the link 38 in the direction of arrow F1 (see FIG. 2). As a result, the auxiliary leg 26 receives a force in the direction of rotation from the storage position SP to the protruding position TP (direction of arrow R2) via the link 38. However, the auxiliary leg 26 is locked at the storage position SP in a normal state by a lock member 42 described later.

When the auxiliary leg 26 is rotated from the state where the auxiliary leg 26 is in the storage position SP toward the protruding position TP about the rotation shaft 28, the rotation shaft 28 slides downward by the link 38. When the rotary shaft 28 slides downward as described above, the position of the lower end 26B of the auxiliary leg 26 at the protruding position TP is lower than that of the structure in which the rotary shaft 28 does not slide downward. The amount of protrusion of the auxiliary leg 26 from the housing 24 is limited to a predetermined range when the slide piece 34 contacts the lower end of the slide groove 36.

Inside the housing 24, a lock member 42 is provided corresponding to each of the auxiliary legs 26.

As shown in FIGS. 4, 6 and 7, the lock member 42 has a first cylinder 44 and a second cylinder 46. In the present embodiment, the first cylinder 44 and the second cylinder 46 are formed in a cylindrical shape, and the first cylinder 44 is accommodated inside the second cylinder 46 coaxially. A common center line of the first cylinder 44 and the second cylinder 46 is a center line CL-1.

In each of the first cylinder 44 and the second cylinder 46, one end in the axial direction is closed by a bottom plate 44B, 46B, respectively, while the other end is an open portion 44A, 46A that is opened. The first cylinder 44 and the second cylinder 46 are arranged such that the open portions 44A and 46A face the upper portion of the auxiliary leg 26 in the depth direction (arrow D direction).

Inside the first cylinder 44, the lock piece 48 is accommodated on the open portion 44A side, and the rotating body 50 is arranged on the bottom plate 44B side.

The rotating body 50 is a cylindrical member and is arranged coaxially with the first cylinder 44. The rotating body 50 is rotatable in the first cylinder 44 about the center line CL-1 in the arrow R3 direction (see FIG. 7).

A weight member 52 extends downward from the rotary body 50. The weight member 52 has an arm portion 54 that passes through the through holes 44C and 46C of the first cylinder 44 and the second cylinder 46, and a weight body 56 provided at the lower end of the arm portion 54. Due to the gravity acting on the weight main body 56, the rotating body 50 rotates about the center line CL-1 so that the weight main body 56 is located below.

A predetermined gap is formed in the circumferential direction of the rotating body 50 between the through holes 44C and 46C and the arm portion 54. The rotating body 50 can rotate within the range of this gap.

The lock piece 48 is a cylindrical member, and an inclined surface 58 is formed on the lower side of the tip portion 48T facing the auxiliary leg 26.

A ridge 60 is formed on the outer peripheral surface of the lock piece 48 along the axial direction. The ridge 60 is housed in a groove 62 formed on the inner peripheral surface of the first cylinder 44. As a result, the lock piece 48 cannot rotate in the arrow R3 direction and is guided so as to slide in the arrow S3 direction without play. The ridge 60 and the concave groove 62 are an example of a first rotation suppressing member.

The lock piece 48 slides between the engagement position KP shown in FIG. 4 and the engagement release position RP shown in FIG. At the engaging position KP, the lock piece 48 has the tip end 48T engaged with the lower side of the slide piece 34 of the rotary shaft 28, and prevents the rotary shaft 28 from sliding downward. On the other hand, the lock piece 48 releases the engagement of the slide piece 34 at the engagement release position RP, and the rotary shaft 28 can slide downward.

As shown in FIG. 12, when the slide piece 34 tries to rise from a state below the lock piece 48, the slide piece 34 comes into contact with the inclined surface 58 from below. When the slide piece 34 further tries to rise in this state, the upward force acting from the slide piece 34 is converted into the force in the disengagement direction (leftward in FIG. 12) by the inclined surface 58. That is, the lock piece 48 is pushed by the rising slide piece 34 and moves toward the engagement release position RP.

Inside the rotating body 50, a tension coil spring 64 is arranged between the rotating body 50 and the lock piece 48. The tension coil spring 64 applies a spring force to the lock piece 48 in the direction toward the engagement release position RP (direction of arrow F2), and is an example of a second biasing member.

A holding member 66 is provided in the first cylinder 44. The holding member 66 includes the rotating body 50, the first protrusion 66A formed on the surface of the lock piece 48 facing the rotating body 50, and the second protrusion formed on the surface of the rotating body 50 facing the lock piece 48. And a protrusion 66B.

The holding member 66 has a state in which the tip of the second protrusion 66B is in contact with the tip of the first protrusion 66A (see FIG. 8) and a state in which the second protrusion 66B is separated from the first protrusion 66A depending on the rotation angle of the rotating body 50. (See FIG. 10).

As shown in FIG. 8, when the tip of the second protrusion 66B is in contact with the tip of the first protrusion 66A, the lock piece 48 is maintained at the engagement position KP against the spring force of the tension coil spring 64. On the other hand, as shown in FIG. 10, when the second protrusion 66B is separated from the first protrusion 66A, the lock piece 48 moves to the disengagement position RP by the spring force of the tension coil spring 64.

As shown in FIG. 1, the relative positions of the first protrusion 66A and the second protrusion 66B are in contact with each other at the angle of the rotating body 50 when the housing 24 is not tilted. Then, as shown in FIG. 2, at the angle of the rotating body 50 when the housing 24 is tilted, the second protrusion 66B is set to be separated from the first protrusion 66A.

Inside the second cylinder 46, a compression coil spring 68 is arranged between the bottom plate 44B of the first cylinder 44 and the bottom plate 46B of the second cylinder 46. The compression coil spring 68 exerts a spring force on the first cylinder 44 in a direction toward the engagement position KP (direction of arrow F3) of the lock piece 48.

As shown in FIG. 4, the first cylinder 44 is formed with a protrusion 44D that enters the through hole 46C of the second cylinder 46. The protrusion 44D faces the inner edge 46D of the through hole 46C of the second cylinder 46. The inner edge 46D is an edge portion on the side of the open portion 46A in the through hole 46C.

As a result, the moving range of the first cylinder 44 in the arrow F3 direction is limited to the predetermined range. Specifically, when the lock piece 48 moves in the arrow F2 direction and is in the disengagement position RP, the movement range of the first cylinder 44 in the arrow F3 direction is such that the lock piece 48 surely moves. Limited to the range of disengagement from the piece 34). In other words, since the first cylinder 44 does not excessively project in the direction of arrow F3, the lock piece 48 moved in the direction of arrow F2 can be reliably disengaged from the rotary shaft 28 (slide piece 34). It That is, the protrusion 44D is an example of a limiting member.

A ridge 70 is formed on the outer peripheral surface of the first cylinder 44 along the axial direction. The ridge 70 is housed in a groove 72 formed in the inner peripheral surface of the second cylinder 46. As a result, the first cylinder 44 cannot rotate in the arrow R3 direction and is guided to slide in the arrow S3 direction without play. The protrusion 70 and the concave groove 72 are an example of a second rotation suppressing member.

Next, the operation of this embodiment will be described.

As shown in FIG. 1, when the vertically placed housing 24 is not tilted, the gravitational force acting on the weight member 52 causes the rotating body 50 to take a predetermined rotation angle. In this state, as shown in FIG. 8, the tip of the first protrusion 66A and the tip of the second protrusion 66B are in contact with each other. The lock piece 48 maintains the engagement position KP even when receiving the spring force of the tension coil spring 64. As shown in FIG. 4, since the lock piece 48 is engaged with the slide piece 34, the rotary shaft 28 does not move downward. The spring force of the leaf spring 40 acts on the auxiliary leg 26 in the protruding direction via the link 38, but the slide piece 34 does not move downward, so the auxiliary leg 26 also maintains the accommodation position.

As shown in FIG. 2, when the vertically placed housing 24 tilts, the gravitational force acting on the weight member 52 causes the rotating body 50 to rotate with respect to the housing 24. In this state, as shown in FIG. 10, the second protrusion 66B is separated from the first protrusion 66A. Due to the spring force of the tension coil spring 64, the lock piece 48 moves to the engagement release position RP. As shown in FIG. 9, since the lock piece 48 does not engage with the slide piece 34 of the rotary shaft 28, the rotary shaft 28 is slidable downward.

In this state, the spring force of the leaf spring 40 causes the auxiliary leg 26 to rotate about the rotation shaft 28 in the arrow R2 direction (toward the protruding position), as shown in FIG. Since the link 38 is bridged between the auxiliary leg 26 and the housing 24, the rotation shaft 28 slides downward as the auxiliary leg 26 rotates.

The sliding of the rotary shaft 28 is restricted by the slide piece 34 contacting the lower end of the slide groove 36. In this state, as shown in FIG. 2, the auxiliary leg 26 is in the protruding position TP. Therefore, even if the housing 24 is tilted, the auxiliary legs 26 support the housing 24, so that the housing 24 can be prevented from falling.

In order to return the auxiliary leg 26 from the projecting position TP to the housing position SP, first, the housing 24 is returned to the non-inclined state (vertical installation state). The gravitational force acting on the weight member 52 causes the rotating body 50 to rotate, and the tips of the first protrusion 66A and the tips of the second protrusion 66B come into contact with each other, so that the lock piece 48 moves to the engagement position KP.

In this state, the auxiliary leg 26 is pushed from the protruding position TP to the housing position SP against the spring force of the leaf spring 40. Since the housing 24 and the auxiliary leg 26 are connected by the link 38, the rotating shaft 28 moves upward. Then, as shown in FIG. 12, the slide piece 34 of the rotary shaft 28 contacts the inclined surface 58 of the lock piece 48.

When the auxiliary leg 26 is further pushed to the storage position SP, the slide piece 34 pushes the lock piece 48 upward. The inclined surface 58 converts the upward force acting from the slide piece 34 into a force in the disengagement direction. Therefore, the lock piece 48, the rotating body 50, and the first cylinder 44 move in the engagement releasing direction against the spring force of the compression coil spring 68. Then, as shown in FIG. 13, when the lock piece 48 retracts from the sliding range of the slide piece 34, the slide piece 34 slides above the lock piece 48.

As shown in FIG. 14, when the slide piece 34 is located above the lock piece 48, the lock piece 48, the rotating body 50, and the first cylinder 44 move in the arrow F3 direction by the spring force of the compression coil spring 68. Then, the lock piece 48 reaches the engagement position KP.

In the present embodiment, as can be seen from the above description, when the auxiliary leg 26 is moved from the accommodation position SP to the protruding position TP, it is moved to the protruding position TP by the spring force of the leaf spring 40 (an example of a biasing member). ing. For example, as compared with the structure in which the auxiliary leg 26 is moved to the projecting position by the gravity acting on the auxiliary leg, the auxiliary leg 26 surely moves to the projecting position TP in a short time, so that the fall of the housing 24 is effectively suppressed.

Moreover, the auxiliary leg 26 surely takes the projecting position TP when the housing 24 is inclined. Since the effect of suppressing the overturning of the housing 24 is not left to the judgment of the user of the computer 22, the overturning of the housing 24 can be reliably suppressed.

When the auxiliary leg 26 is in the storage position SP, the auxiliary leg 26 does not protrude from the housing 24. Therefore, the auxiliary leg 26 does not get in the way, and the usage environment of the computer 22 is good.

The auxiliary leg 26 is kept attached to the housing 24 by the rotating shaft 28 and the link 38. For example, when the housing 24 is used vertically, it is not necessary to attach the auxiliary leg 26 to the housing 24, and the work load when using the computer 22 does not increase.

The auxiliary leg 26 is rotatably attached to the housing 24 by a rotation shaft 28. That is, the auxiliary leg 26 can be moved between the accommodation position SP and the protruding position TP with a simple structure by rotating the auxiliary leg 26 about the rotation axis 28.

The rotating shaft 28 slides in the up-down direction of the housing 24 placed vertically. By sliding the rotating shaft 28 downward when the auxiliary leg 26 is at the protruding position TP, the auxiliary leg 26 also moves downward. Since the lower end of the auxiliary leg 26, that is, the portion that supports the load of the inclined housing 24 is located below, the load of the housing 24 can be supported by the auxiliary leg 26 while the inclination angle of the housing 24 is small.

A link 38 is bridged between the housing 24 and the auxiliary leg 26. Therefore, when the auxiliary leg 26 moves to the protruding position TP, the rotary shaft 28 can be moved downward. In other words, it is possible to realize a structure in which the auxiliary leg 26 moves to the protruding position TP as the rotary shaft 28 moves downward.

In this embodiment, the leaf spring 40 is used as an example of the biasing member. That is, the auxiliary leg 26 can be moved from the accommodation position SP to the protruding position TP with a simple structure using the leaf spring 40 without using a driving source such as a motor or an actuator.

The leaf spring 40 may be bridged between the housing 24 and the auxiliary leg 26, but in the above embodiment, it is bridged between the housing 24 and the link 38. Since the end 24A (see FIG. 11) of the link 38 on the housing 24 side does not slide with respect to the housing 24, the attachment state of the leaf spring 40 to the link 38 is stable.

The lock member 42 may lock the auxiliary leg 26 itself in a state where the auxiliary leg 26 is in the storage position SP, but in the present embodiment, the auxiliary leg 26 is prevented by moving the rotating shaft 28 downward. 26 is locked at the accommodation position SP. Since the lock member 42 does not directly lock the auxiliary leg 26, it has little influence on the shape and movement range of the auxiliary leg 26, and the degree of freedom of the shape and movement range of the auxiliary leg 26 is high.

The lock member 42 has a lock piece 48 movable between the engagement position KP and the engagement release position RP. When the lock piece 48 moves to the engagement release position RP, the lock of the rotary shaft 28 by the lock member 42 can be released. Although the lock piece 48 is biased to the engagement release position by the tension coil spring 64, the lock piece 48 can be maintained at the engagement position KP by the holding member 66. Then, when the holding of the lock piece 48 by the holding member 66 is released, the lock piece 48 can be reliably moved to the disengagement position RP by the spring force of the tension coil spring 64.

The holding member 66 includes the rotating body 50, a first protrusion 66A formed on the lock piece, and a second protrusion 66B formed on the rotating body 50. Substantially, if two protrusions are formed on the rotating body 50 and the lock piece 48, the lock piece 48 can be held and released at the engagement position KP, which is a simple structure. Further, by rotating the rotating body 50, the lock piece 48 can be held and released at the engagement position KP, and a complicated mechanism is not required.

The lock piece 48, the tension coil spring 64, and the rotating body 50 are housed in the first cylinder 44. That is, the lock piece 48, the tension coil spring 64, and the rotating body 50 can be integrally held by the first cylinder 44.

A protrusion 60 is formed on the lock piece 48, and the protrusion 60 is engaged with the groove 62 of the first cylinder 44. This can prevent the lock piece 48 from rotating in the circumferential direction with respect to the first cylinder 44. Further, the lock piece 48 can be guided so as to move without rattling between the engagement position KP and the engagement release position RP.

The first cylinder 44 is biased in the arrow F3 direction (see FIG. 7) by the spring force of the compression coil spring 68. The arrow F3 direction is the direction in which the lock piece 48 moves to the engagement position KP. That is, the spring force of the compression coil spring 68 can reliably move the lock piece 48 to the engagement position KP.

Moreover, the movement range of the first cylinder 44, which receives the spring force of the compression coil spring 68, ensures that the lock piece 48 is engaged with the rotary shaft 28 (slide piece 34) when the lock piece 48 is in the engagement release position RP. Limited to the range that can be released. Therefore, the lock piece 48 can be reliably separated from the slide piece 34 by the operation of returning the auxiliary leg 26 from the protruding position TP to the housing position SP.

The first cylinder 44 and the compression coil spring 68 are housed in the second cylinder 46. That is, the second cylinder 46 can integrally hold the first cylinder 44 and the compression coil spring 68.

A ridge 70 is formed on the first cylinder 44, and the ridge 70 is engaged with the concave groove 72 of the second cylinder 46. This can prevent the first cylinder 44 from rotating in the circumferential direction (direction of arrow R3 in FIG. 6) with respect to the second cylinder 46. Further, the first cylinder 44 can be guided so as to move in the arrow axis direction (the arrow S3 direction in FIG. 6) without play.

An inclined surface 58 is formed on the lock piece 48. Thereby, the lock piece 48 can be moved to the disengagement position RP by using the force acting on the lock piece 48 from the slide piece 34 moving upward. The lock piece 48 can be moved to the disengagement position RP by an operation of moving the auxiliary leg 26 from the protruding position TP to the accommodation position SP, which is excellent in operability.

In the above embodiment, the housing 24 has a rectangular parallelepiped box shape. Therefore, when the housing 24 is placed vertically, the housing 24 is vertically long, that is, has a posture that is longer in the vertical direction than in the horizontal direction, and thus it is easy to fall. Since the auxiliary leg 26 is provided on the side surface 24S located on the side when the housing 24 is placed vertically, it is possible to prevent the auxiliary leg 26 from tipping over in a vertically placed state.

As a structure for moving the auxiliary leg between the housing position and the protruding position with respect to the housing 24, a structure other than the above-described embodiment may be adopted. For example, in a vertically installed case, the auxiliary leg may be rotated by a vertical rotation axis. In this structure, the auxiliary leg rotates in the horizontal direction with respect to the vertically installed housing, and moves between the accommodation position and the protruding position.

Further, in a vertically installed case, the auxiliary leg may slide horizontally to move between the accommodation position and the protruding position.

In the above description, the computer 22 having the housing 24 is described as an example of the electronic device, but the electronic device is not limited to this. For example, the electronic device may be an external storage device, a display, a speaker, or the like. Furthermore, the electronic device may be a server rack that mounts one or a plurality of servers.

Although the embodiments of the technology disclosed in the present application have been described above, the technology disclosed in the present application is not limited to the above, and may be variously modified and implemented without departing from the scope thereof. Of course,
