Description

Portable terminal

The present invention relates to a portable terminal (por tab le termina l) in which a tunnel portion is opened on a side surface of a casing, and an antenna is accommodated in an open tunnel portion. Background technique

In a portable terminal, it is known that a tunnel portion is provided in a casing, and an antenna is slidably disposed in a tunnel portion. When used, an antenna can be pulled out from a tunnel, and when not in use, an antenna can be inserted into a tunnel to form an antenna. Portable terminal.

The antenna is formed of a resin tube to obtain slidability for the tunnel portion. Alongside, the resin tube has a large outer diameter and a large outer diameter. Therefore, the size of the casing accommodating the antenna and the dimension in the thickness direction are large, which hinders the thinning and miniaturization of the portable terminal (for example, Patent Document 1).

Problem to be solved by the invention

However, as an antenna in recent years, an antenna which is foldably formed by being hinged in a state where it is pulled out from the casing is known.

In the state in which the antenna is pulled out from the casing, the shaft rotation of the antenna is restricted so that the hinge shaft is along the thickness direction of the casing, so that the front end of the antenna does not face the user of the portable terminal, that is, the antenna is The housing is not folded in the thickness direction.

The present invention has been made to solve the above problems, and an object thereof is to provide a portable device capable of restricting shaft rotation of an antenna and reducing a dimension in a width direction and a thickness direction of a casing in a state in which an antenna is pulled out from a casing. terminal.

Solution for solving problems The portable terminal of the present invention includes: a housing; a tunnel portion opened on a side surface of the housing and having a sectional shape other than a perfect circle; and an antenna housed in the tunnel portion, the antenna including: a base end member and a front end member, forming a slidable cylindrical shape along the tunnel portion; an articulated shaft, the base end member and the front end member are respectively connected in a diametrical direction; the bracket is provided to be insertable a base end member and an insertion hole of the front end member are fixed to the housing to connect the insertion hole to the tunnel portion; a first flange portion is provided on an outer circumferential surface of the base end member a shape other than a perfect circle; a flange receiving portion provided on the tunnel portion side of the insertion hole to engage the first flange portion; and a second flange portion compared to the base portion The first flange portion of the end member is provided on an end side opposite to the hinge shaft, and corresponds to a cross-sectional shape of the tunnel portion.

The tunnel portion is formed into a cross-sectional shape other than the perfect circle, and the second flange portion corresponds to the cross-sectional shape of the tunnel portion. Therefore, when the antenna is slid in the tunnel portion from the accommodating state of the antenna to the pulled-out state, the axial rotation of the antenna is restricted by the second flange portion.

Further, the first flange portion is formed into a shape other than a perfect circle, and the first flange portion can be engaged with the flange receiving portion.

Therefore, the first flange portion is engaged with the flange receiving portion in the pulled-out state in which the antenna is pulled out from the casing, thereby restricting the shaft rotation of the antenna.

Thereby, the shaft rotation of the antenna is restricted in a state of being pulled out from the accommodation state of the antenna or in a state in which the antenna is pulled out.

Further, in the present invention, since the resin pipe which has been conventionally used is not required, the casing size (the width direction dimension and the thickness direction dimension) corresponding to the wall thickness of the pipe can be reduced by one time.

Further, in the portable terminal of the present invention, the first flange portion restricts shaft rotation of the antenna in a pulled-out state in which the antenna is pulled out from the tunnel portion, so that the hinge shaft is along In the thickness direction of the casing, the second flange portion restricts shaft rotation of the antenna in a state in which the antenna is accommodated in the tunnel portion, so that the hinge shaft is along the casing Thickness direction.

In the pulled-out state of the antenna, the hinge shaft is rotated in the thickness direction of the casing, and the first flange portion restricts the shaft rotation of the antenna. In addition, in the accommodating state of the antenna, the hinge shaft is along the thickness direction of the housing,

2 The flange portion limits the shaft rotation of the antenna.

Thereby, in the pulled-out state of the antenna or the accommodated state of the antenna, the hinge shaft can be made to follow the thickness direction of the casing, so that the front end member of the antenna can be folded only in the width direction of the casing.

Further, in the portable terminal of the present invention, the second flange portion has a circular arc portion and abuts the The plane of the straight portion of the circular arc surface is substantially D-shaped.

By forming the first flange portion into a substantially D-shape in a circular arc portion and a straight portion, the portion where the straight portion and the straight portion intersect can be formed as a protruding portion (that is, a flat corner portion).

Thereby, in a state where the second flange portion is housed in the tunnel portion, the rotation of the second flange portion with respect to the tunnel portion can be reliably prevented by the protruding portion (planar corner portion).

Further, in the portable terminal of the present invention, the planar corner portion of the second flange portion is an acute angle. In the present invention, since the plane corner portion in the second flange portion is an acute angle, the plane corner portion is longer than the axis of the antenna in comparison with other portions (arc portion).

Therefore, in the present invention, the rotation of the second flange portion centering on the axis of the antenna is restricted by the planar corner portion, whereby the first flange portion and the flange receiving portion are reliably engaged.

Effect of the invention

According to the portable terminal of the present invention, the tunnel portion is formed into a cross-sectional shape other than a perfect circle to make the

The flange portion corresponds to the cross section of the tunnel portion, and the first flange portion is formed into a shape other than a perfect circle, and the first flange portion is engageable in the flange receiving portion.

Further, according to the portable terminal of the present invention, since the resin pipe which has been conventionally used is not required, the casing size (the width direction dimension and the thickness direction dimension) which is twice the wall thickness of the pipe can be reduced.

As shown in Figs. 6 and 7, the antenna 16 has: a base end member 25; a front end member 26; an articulated shaft 27; a bracket 31; a first flange portion 35; a flange receiving portion 36 and a first flange portion 38.

The base end member 25 is formed in a cylindrical shape which is slidable along the tunnel portion 14.

The base end member 25 has a front end 25A branched into a fork shape, and a first flange portion 35 and a first flange portion 35 are provided on the base end 25B.

The front end member 26 is formed in a cylindrical shape which is slidable along the tunnel portion 14.

The front end member 26, the base end 26A is inserted into the front end 25A branched into a fork shape.

Further, a front end stopper 41 is provided on the front end 26B of the front end member 26.

The hinge shaft 27 is penetrated in the diametrical direction of the proximal end member 25 and the distal end member 26 in the distal end 26A of the proximal end member 25 and the proximal end 26A of the distal end member 26.

Thereby, the front end 25A of the proximal end member 25 and the proximal end 26A of the distal end member 26 are rotatably coupled by the hinge shaft 27.

In this state, the hinge shaft 27 is disposed so as to be along the thickness direction of the casing 11.

Therefore, the front end member 26 can be swayed in the width direction of the casing 11 with the hinge shaft 27 as an axis.

The bracket 31 has: a bracket body 32 connectable to the tunnel portion 14; and a mounting protrusion 33 projecting from the bracket body 32 in the width direction of the casing 11.

As shown in Fig. 4, the mounting projection 33 is fixed to the housing 11 by screws 43.

As shown in Figs. 6 and 7, the bracket body 32 is formed in a cylindrical shape, and is provided with a socket 32A into which the base end member 25 and the front end member 26 are respectively inserted.

In a state where the mounting protrusion 33 is fixed to the casing 11 by a screw 43 (refer to FIG. 4), the bracket body 32 is mounted on the casing 11 such that the insertion hole 32A is in the tunnel portion 14 (refer to FIG. 4). On the continuous. A flange receiving portion 36 is formed on the base end 32B of the bracket body 32.

The first flange portion 35 is provided on the outer peripheral surface of the proximal end member 25 (base end 25B) and has a shape other than a perfect circle.

Specifically, the first flange portion 35 is formed in a substantially D-shaped cross section having the first circular arc portion 35A and the first straight portion 35B adjacent to the first circular arc portion.

The first flange portion 35 is formed to be engaged with the flange receiving portion 36.

Further, the first flange portion 35 can position the antenna 16 at the pull-out position by being attached to the base end 32B of the bracket body 32 in the pulled-out state until the antenna 16 is pulled out to the pull-out position P1.

That is, the first flange portion 35 also serves as a stopper for positioning the antenna 16 at the pull-out position P1.

A flange receiving portion 36 disposed in the tunnel portion 14 side of the insertion hole 32A, an opening 36A (see FIG. 8) side of the display unit 18 ₀

When the opening 36A is formed in the flange receiving portion 36 on the display portion 18 side, the first flange portion 35 is engaged with the flange in a state where the first straight portion 35B of the first flange portion 35 faces the opening 36A. In section 36.

In a state where the first flange portion 35 is engaged with the flange receiving portion 36, the flange receiving portion 36 can prevent the shaft of the first flange portion 35 from rotating.

In other words, when the antenna 16 is pulled out from the tunnel portion 14 (see FIG. 4) to the pull-out position P1, the first flange portion 35 can be engaged with the flange receiving portion 36 to restrict the antenna. The shaft of 16 rotates.

Thereby, the hinge shaft 27 can be held so as to be along the thickness direction of the casing 11.

The first flange portion 38 is provided at a position corresponding to the cross-sectional shape of the tunnel portion 14 as compared with the end portion side of the proximal end member 25 which is provided on the opposite side of the hinge shaft 27.

The second flange portion 38 is formed in a substantially D shape in a plane having a first circular arc portion (circular arc portion) 38A and a second straight portion (linear portion) 38B adjacent to the circular arc surface (see also Fig. 5).

By forming the first flange portion 38 in a substantially D-shape in the plane of the first circular arc portion 38A and the first straight portion 38B, the portion where the first circular arc portion 38A and the first straight portion 38B intersect can be formed into a plane angle. Department (protrusion) 38C.

Thereby, in a state where the second flange portion 28 is housed in the tunnel portion 14, the second flange portion 38 can be reliably prevented from rotating with respect to the tunnel portion 14 by the planar corner portion 38C. Here, as shown in FIG. 5, the plane corner portion 38C is formed at an acute angle.

Therefore, the planar corner portion 38C of the second flange portion 28 is longer than the other portions, i.e., the second circular arc portion 38A and the second straight portion 38B, from the axis of the antenna 16. Therefore, the rotation of the second flange portion 28 centering on the axis of the antenna 16 is restricted, whereby the first flange portion 35 and the flange receiving portion 36 are reliably engaged.

The first flange portion 38 can restrict the rotation of the antenna 16 so that the hinge shaft 27 is along the housing 1 in a housing state in which the antenna 16 is accommodated in the tunnel portion 14 at the accommodating position P2 (refer to FIG. 6). The thickness direction of 1.

As described above, the tunnel portion 14 is formed into a cross-sectional shape other than a perfect circle, and the first flange portion 38 corresponds to the cross-sectional shape of the tunnel portion 14. Thereby, when the antenna 16 is pulled out from the accommodated state of the antenna 16 to the pulled-out state and slides in the tunnel portion 14, the shaft rotation of the antenna 16 is restricted by the first flange portion 38.

Further, the first flange portion 35 is formed into a shape other than a perfect circle, and the first flange portion 35 is engageable with the flange receiving portion 36.

Thereby, in the pulled-out state in which the antenna 16 is pulled out from the casing 11, the first flange portion 35 is engaged with the flange receiving portion 36, and the shaft rotation of the antenna 16 is restricted.

Further, since the portable terminal 10 does not require a resin tube that has been conventionally used in the tunnel portion 14, it is possible to reduce the size of the casing (the width direction dimension and the thickness direction dimension) which are twice the thickness of the tube. .

Further, the first flange portion 35 restricts the shaft rotation of the antenna 16 so that the hinge shaft 27 is along the thickness direction of the casing 1 1 in the pulled-out state of the antenna 16. Further, the second flange portion 38 restricts the shaft rotation of the antenna 16 so that the hinge shaft 27 is along the thickness direction of the casing 11 in the accommodated state of the antenna 16.

Thereby, in the pulled-out state of the antenna 16 or the accommodated state of the antenna 16, the hinge shaft 27 can be made along the thickness direction of the casing 11, so that the front end member 26 of the antenna 16 can be only in the width direction of the casing 11. (arrow A direction) folds up.

Further, the portable terminal of the present invention is not limited to the above embodiment, and can be appropriately modified and improved.
