Description

  The present invention relates to a portable terminal that connects two housings so as to be relatively movable.

  A portable communication terminal (hereinafter, simply referred to as a terminal) that transmits and receives various data by wireless transmission and reception such as a cellular phone is required to be compact when not in use. Therefore, it is required to make the monitor screen easier to see and to improve the operability of the operation keys. Accordingly, the terminal can be folded by connecting the first housing and the second housing so as to be rotatable by a hinge, or the second housing can be slidably provided with respect to the first housing. There is a configuration in which the terminal is expanded by a slide operation.

  Here, in a slide-type terminal that allows the second housing to slide with respect to the first housing, the slide mechanism slides in order to smoothly slide the first housing and the second housing. A minimum clearance is provided in a direction perpendicular to the direction. On the other hand, when there is a clearance in the slide mechanism, the slide mechanism is slid from the closed state in which the first housing and the second housing are overlapped or from the state in which the second housing is overlapped with the first housing. In the open state, rattling occurs between the first housing and the second housing, which impairs the feeling of use. Therefore, it is desirable to prevent the first housing and the second housing from rattling in either the closed state or the open state.

On the other hand, Patent Document 1 discloses a configuration in which an elastic member is sandwiched between a first housing and a second housing, and in this configuration, the first and second housings are provided. The convex portion abuts against the elastic member provided on the other side, and the convex portion absorbs play (play) by elastically deforming the elastic member.

However, the casing of an actual terminal is colored by painting in order to improve design. And the thickness of the coating film formed in the surface of a housing | casing may differ, for example, when the number of times of repeated coating of paint differs according to the paint color. Then, in the configuration described in Patent Document 1, when the elastic member hits the coating film on the surface of the first and second casings, the contact condition with the elastic member depends on the thickness of the coating film, that is, the color of the casing. Will be different. As a result, when the coating film is thick, there is a problem that the elastic member between the first housing and the second housing is hard to hit and the opening / closing operation by the slide is difficult to perform.
Accordingly, an object of the present invention is to provide a portable terminal capable of smoothly performing the sliding operation while suppressing backlash in the closed state and the open state.

The present invention employs the following means in order to solve the above problems.
That is, the present invention is provided between the first housing, the second housing disposed to face one surface of the first housing, the first housing, and the second housing. Between the closed state in which the body and the second housing are overlapped and the open state in which the second housing is relatively moved in a direction along one surface of the first housing. A sliding mechanism that allows the body to slide, and an end of one surface of the first housing, but abuts against the second housing in at least one of a closed state and an open state, and the second housing is An elastic member that presses in a direction away from the body, and the elastic member has a tongue that projects from the first housing to the second housing, and the tongue is in contact with the second housing The first housing is formed to have a gap.

  According to the present invention, in at least one of the closed state and the open state, the tongue portion of the elastic member abuts against the second housing, whereby the second housing can be pressed in a direction away from the first housing. . Further, in this state, a gap is formed between the tongue of the elastic member and the first housing, so that the thickness of the coating film varies depending on the coating color of the first housing and the second housing. The space where the tongue portion of the elastic member is elastically deformed can be secured. Thereby, it is possible to smoothly perform the sliding operation while suppressing backlash between the first housing and the second housing.

It is a perspective view which shows the external appearance of the portable terminal concerning this embodiment. It is a side view when a portable terminal is made into an open state. It is a perspective view which shows the state which expand | deployed the 1st housing | casing and the 2nd housing | casing. It is sectional drawing which shows the elastic member provided between the 1st housing | casing and the 2nd housing | casing. It is sectional drawing for showing the deflection amount of an elastic member. It is sectional drawing which shows the state by which the elastic member was inserted | pinched between the 1st housing | casing and the 2nd housing | casing.

The best mode for carrying out a portable terminal according to the present invention will be described below with reference to the accompanying drawings. However, the present invention is not limited only to these examples.
As shown in FIGS. 1 and 2, the mobile terminal 1 includes a first housing 2 and a second housing 3 that are arranged to face each other.

The first housing 2 is formed in a flat rectangular thin shape, and has a main surface 4 as a rectangular surface facing the second housing 3, and a numeric keypad or the like in a range on one side along the long side 4 a. The operation unit 5 in which various buttons 5a are arranged is provided. As shown in FIG. 3, the first housing 2 includes a substrate 6 connected to various buttons and a microphone of the operation unit 5 as an internal configuration, a battery serving as a power source, and the like.
Further, the second housing 3 is formed in a thin flat rectangular shape having the same shape as the first housing 2 in the present embodiment, and has a facing surface 7 facing the main surface 4 of the first housing 2. is doing.

  The second housing 3 is attached to the first housing 2 by a slide mechanism (not shown) provided between the main surface 4 of the first housing 2 and the facing surface 7 of the second housing 3 facing each other. It is provided so as to be relatively slidable. And in this embodiment, in the portable terminal 1, the 1st housing | casing 2 and the 2nd housing | casing 3 are the directions along the long side 4a from the closed state with which the main surface 4 and the opposing surface 7 overlapped without shifting | deviating. Can be expanded relative to the moving direction A by sliding. The specific configuration of the slide mechanism is not limited in any way, and a known slide mechanism can be appropriately employed.

Here, as shown in FIG. 3, in order to suppress backlash between the first housing 2 and the second housing 3 in the open state, a sheet-like shape is provided between the first housing 2 and the second housing 3. The clearance adjustment member 30 is provided.
For example, the clearance adjusting member 30 is fixed to the first housing 2. The clearance adjustment member 30 may be fixedly provided on the second housing 3 side.
As shown in FIG. 4, in the first casing 2, the second casing 3 projects toward the second casing 3 at the end 2 a in the direction in which the second casing 3 slides and opens with respect to the first casing 2. One rib 31 is formed. On the other hand, in the second casing 3, the position facing the first rib 31 in the second casing 3 when the second casing 3 is opened, and the first rib 31 in the second casing 3 when the second casing 3 is closed. A second rib 32 that protrudes toward the first housing 2 is formed at the opposite position.

As shown in FIGS. 3 and 4, the clearance adjustment member 30 is formed so as to ride on the base surface 33 fixed to the main surface 4 of the first housing 2 by fixing means such as screws and the first rib 31. And a tongue 34. An end 33 a of the base surface 33 is inserted into a groove 35 formed in the base of the first rib 31.
The tongues 34 are provided at both ends in the width direction of the first housing 2. The tongue 34 is formed so as to protrude from the end 33 a of the base surface 33 toward the second housing 3, and extends along the surface of the first rib 31, and the tip 34 a extends from the first rib 31 to the second housing 3. It protrudes so as to be separated from the side. And the front-end | tip part 34a of the tongue part 34 is formed so that it may be located between these in the state with which the 1st rib 31 and the 2nd rib 32 were facing. At this time, the tip 34 a of the tongue 34 is elastically deformed toward the first rib 31 by abutting against the second rib 32, and the second rib 32 is separated from the first rib 31 by the repulsive force. It is pressing in the direction of separating.

  Here, as shown in FIGS. 4 to 6, the tip 34 a of the tongue 34 has a second state shown in FIG. 6 with respect to a free state (a state indicated by a solid line in FIG. 5) where the second rib 32 does not interfere. In the state in which the rib 32 interferes, it is elastically deformed to the side approaching the first rib 31 due to the interference with the second rib 32. Here, of the coating colors applied to the first casing 2 and the second casing 3, the tip of the tongue 34 in a state in which the second rib 32 applied with the coating color with the thickest coating film interferes. The gap dimension s between the first rib 31 and the second rib 32 is set to be larger than the deflection amount b of the portion 34a.

According to such a configuration, the tip 34 a of the tongue 34 abuts against the second rib 32 and elastically deforms, thereby pressing the second rib 32 in a direction away from the first rib 31, thereby The backlash between the body 2 and the second housing 3 is suppressed.
At this time, the first rib 31 and the second rib 32 are larger than the deflection amount b of the distal end portion 34a of the tongue portion 34 in the state in which the second rib 32 coated with the paint color having the thickest coating interferes. The gap dimension s is formed to be larger. Thereby, even if it is a case where the coating film with the thickest coating color is given, clearance c is formed between the front-end | tip part 34a of the tongue part 34, and the 1st rib 31. FIG. That is, the tip end portion 34 a of the tongue portion 34 is not sandwiched between the first housing 2 and the second housing 3. When the coating is applied with a thinner coating color, the clearance c becomes larger. In this way, the variation in the clearance between the first housing 2 and the second housing 3 due to the paint color can be absorbed by the tongue 34. As a result, the sliding operation of the first housing 2 and the second housing 3 is not tightened while suppressing backlash between the first housing 2 and the second housing 3 in any paint color. It is possible to perform a sliding operation smoothly.

  Further, the tongue portions 34 are provided at both ends in the width direction of the first housing 2, which are orthogonal to the sliding direction of the first housing 2 and the second housing 3. Thus, the tongue 34 is sufficiently small with respect to the width of the first housing 2. Thereby, when the front-end | tip part 34a contact | abuts the 2nd housing | casing 3, the tongue part 34 tends to elastically deform to the 1st housing | casing 2 side, and slide operation | movement with the 1st housing | casing 2 and the 2nd housing | casing 3 is carried out. Can be prevented from being caused by friction, and can contribute to a smooth sliding operation.

The portable terminal of the present invention is not limited to the above-described embodiments described with reference to the drawings, and various modifications can be considered within the technical scope.
For example, the first housing 2 and the second housing 3 are flat rectangular and have the same shape, but the present invention is not limited to this, and various shapes can be applied. Different shapes and sizes may be used.
Further, the second rib 32 faces the first rib 31 when the first housing 2 and the second housing 3 are in the closed state and in the open state. Instead, it may be provided only in either one.
Furthermore, in the above-described embodiment, the mobile terminal has been described. However, the present invention is not limited to this. For example, a laptop personal computer, an electronic dictionary, It goes without saying that the present invention can be effectively applied to various portable terminals such as PDA (Personal Data Assistance).
In addition to this, as long as it does not depart from the gist of the present invention, the configuration described in the above embodiment can be selected or changed to another configuration as appropriate.
