Embodiment 1

[0072] Such as figure 1 As shown, the bending spring 1 of the present embodiment 1 is generally formed in a crescent shape or a deformed fan shape that is roughly bilaterally symmetrical. figure 1 The middle left side has a generally wedge-shaped end 2 and the right side also has a generally wedge-shaped other end 3 .

[0073] It should be noted that, in figure 1 In , the shape of the unloaded state in which no load acts on the bending spring 1 is shown, and in figure 1 The left-right direction refers to the approaching and separating direction S between one end 2 and the other end 3, the up-down direction refers to the width direction W perpendicular to the approaching and separating direction S, and the front-to-back direction on the paper refers to the thickness direction T. Regarding the thickness direction T, for the sake of easy description, the direction from the back side to the outside side of the paper is defined as positive.

Embodiment 2

[0122] The bending spring 11 of the present embodiment 2 shown in FIG. 8A and FIG. 8B is the figure 1 In the bending spring 1 shown in Example 1, the most curved inner beam portion 7 is replaced with a metal beam portion 71 . When the beam portion 71 made of metal is embedded to figure 1 In the bending spring 1 of the illustrated embodiment 1, when the main body part integrally formed in the form of the beam part 71 is removed, the groove part for fitting is provided on the lower side in FIG. 8 of one end part and the other end part. correspond.

[0123] In other words, on both ends of the metal beam portion 71 shown in FIG. 8A and FIG. 8B in the approaching and separating direction S, curls (curls) in the form of partial arcs of 180 degrees or more, here about 270 degrees, are formed. ) portions 71L, 71R, groove portions 21L, 31R are formed on the one end portion 21 and the other end portion 31 constituting the bending spring 11, and the curl portions 71L, 71R can be fitted...

Embodiment 3

[0130] The bending spring 101 of the third embodiment includes, as shown in FIG. 10 , individual one-side connection portions 121 to 124 and individual other-side connection portions 131 to 134 respectively corresponding to the beam portions 104 to 107 . The individual one-side connection portion 124 includes a hole-shaped one-side bearing portion 124a, and the individual other-side connection portion 134 includes a hole-shaped other-side bearing portion 134a.

[0131] In other words, one end part of the bending spring 101 includes a plurality of individual one-end connecting parts 121-124 connecting each of the four beam parts 104-107 to the one-side bearing part 124a, and the other end part includes four The other end connection parts 131-134 which connect each beam part of the beam part 104-107 and the other side bearing part 134a are connected.

[0132] Moreover, a plurality of individual one-end connection parts 121-124 have a structure stacked on each other along the rad...

Abstract

The present invention pertains to a bow spring which generates impelling force in a mutual separation direction on the basis of close displacement in the relative contact / estrangement direction of one end section and another end section, said spring including a plurality of beam sections extending in an extension direction curving between the one end section and the other end section. The plurality of beam sections are arranged in parallel in a width-ways direction perpendicular to the contact / estrangement direction, and in the gaps between beam sections in at least one assembly among assemblies wherein a plurality of beam sections are adjacent to one another, the width in the width-ways direction (W) of the beam section on the outer side of the bend is wider than the width in the width-ways direction of the beam section which is on the inner side of the bend. Additionally, the length in the contact / estrangement direction of the beam section on the outer side of the bend is shorter than the length in the contact / estrangement direction of the beam section on the inner side of the bend. Furthermore, the one end section, the other end section and at least one beam section among the plurality of beam sections are integrally molded on the same plane surface by means of a synthetic resin.

Description

technical field [0001] The present invention relates to a sliding device capable of sliding a sub-body relative to a main body in a device having a main body and a sub-body, such as a portable phone, a portable terminal, and the like, and a bending spring used for the sliding device. Background technique [0002] As an electronic device such as a portable telephone, there is known a main body having a numeric keypad or a microphone, a sub-body having a liquid crystal display device or a speaker, and a sliding device capable of sliding the sub-body relative to the main body. device of. In this electronic device, by sliding the auxiliary body part connected through the sliding device relative to the main body part, it is possible to position the speaker at the user's ear, position the microphone near the user's mouth or chin, or expose the number keys to communicate with the user. The action of juxtaposing monitors. [0003] A device described in Patent Document 1 exists as ...
