Description

  The present invention relates to a slide unit capable of holding a second member slidable with respect to a first member at a predetermined position.

  An electric device such as a cellular phone incorporates a slide mechanism that allows the second member to slide relative to the first member. For example, Patent Document 1 discloses a mobile phone in which a slide mechanism is incorporated, and a transmitter body housing constituting a first member and a receiver body housing constituting a second member are arranged via a slide mechanism. They are slidably connected to each other. The slide mechanism includes a guide groove provided in the second member and a ball plunger provided in the first member.

  The ball plunger includes a ball, a case that rotatably supports the ball, and a coil spring that is accommodated in the case and biases the ball into the guide groove. The ball plunger ball fits into the guide groove. When the second member is slid with respect to the first member, the ball of the ball plunger rolls along the guide groove.

  The slide mechanism of Patent Document 1 is configured to be able to hold the second member at a predetermined position with respect to the first member. That is, two ball plungers are provided in the relative movement direction of the first member (in other words, the length direction of the guide groove). The guide groove of the second member is provided with two recesses deeper than the guide groove in the length direction of the guide groove. When the second member slides to a predetermined position with respect to the first member, the balls of the two ball plungers fit into the two concave portions of the guide groove, and the second member is held at the predetermined position.

JP 2004-235897 A

  In the slide mechanism described in Patent Document 1, since the ball plunger and two concave portions into which the balls of the ball plunger are fitted are provided in the length direction of the guide groove, the holding force for holding the second member in a predetermined position is provided. There is an advantage that can be increased.

  However, when the second member is slid with respect to the first member, the balls of the two ball bearings roll on the guide groove, which causes a problem that the slide resistance of the second member is large.

  Therefore, the present invention provides a slide unit that can increase the holding force for holding the second member at a predetermined position with respect to the first member, and can reduce the sliding resistance of the second member relative to the first member. The purpose is to provide.

  In order to solve the above problems, the present invention provides a first member having a convex portion and a concave portion arranged away from the convex portion in one direction, and a convex portion arranged away from the concave portion and the concave portion in the one direction. And a second member that is slidable relative to the first member, the second member with respect to the first member, and the convex portion of the first member and the first member The slide unit is slidable relatively in the one direction from an engagement position where the concave portions of the two members are engaged and the concave portions of the first member and the convex portions of the second member are engaged.

  According to the present invention, at the engagement position, the convex portion of the first member and the concave portion of the second member are engaged, and the concave portion of the first member and the convex portion of the second member are engaged. The holding force held at the engagement position can be increased. Further, since the second member can slide relative to the first member in one direction from the engagement position (that is, the direction in which the convex portion of the first member and the convex portion of the second member are separated), It can prevent that the convex part of a 1st member and the convex part of a 2nd member contact, and the slide resistance of the 2nd member with respect to a 1st member becomes large.

The non-contact of the convex part 14 is maintained.

  As shown in FIG. 5 (d), the second member 2 is finally separated from the first member 1. As shown in FIG. 7, since the leaf spring 11 and the first member 1 do not engage with each other at the opposing position, the second member 2 can be smoothly pulled out from the first member 1.

  According to the slide unit of the present embodiment, the following effects can be obtained. At the engaging position, the convex portion 5 of the first member 1 and the concave portion 13 of the second member 2 are engaged, and the concave portion 6 of the first member 1 and the convex portion 14 of the second member 2 are engaged. The holding force for holding the two members 2 in the engaged position can be increased. Further, the second member 2 is slidable with respect to the first member 1 in the rearward direction (that is, the direction in which the convex portion 5 of the first member 1 and the convex portion 14 of the second member 2 are separated). Therefore, it can prevent that the convex part 5 of the 1st member 1 and the convex part 14 of the 2nd member 2 contact, and the slide resistance of the 2nd member 2 with respect to the 1st member 1 becomes large.

  Since the second member 2 can be extracted from the first member 1, the second member 2 can be separated from the first member 1.

  Since the second member 2 includes the leaf spring 11 and the second member main body 12 to which the leaf spring 11 is attached, the elastically deformed portion and the rigid portion can be separated, and the leaf spring 11 that is repeatedly elastically deformed can be separated. The lifetime can be extended. Further, since the notches 17a and 17b are provided in the second member body 12, the vicinity of the concave portion 13 and the convex portion 14 of the leaf spring 11 can be elastically deformed in the notches 17a and 17b.

  The portion where the first member 1 and the second member 2 are engaged with each other by unevenness and the portion where the first member 1 and the second member 2 slide relative to each other are distributed to the upper surface 1a and the side surface 1b of the first member 1. Thus, both the concave-convex engagement and the slide can be stabilized.

  FIG. 8 shows a slide unit according to the second embodiment of the present invention. The slide unit of this embodiment also includes a first member 1 and a second member 22 that can slide with respect to the first member 1. Since the structure of the 1st member 1 is the same as the 1st member 1 of 1st embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted. The second member 22 includes a second member main body 23 and a leaf spring 11 attached to the second member main body 23. Since the configuration of the leaf spring 11 is the same as that of the leaf spring 11 of the first embodiment, the same reference numerals are given and description thereof is omitted.

  In the second member body 12 of the first embodiment, notches 17a and 17b are provided at both ends of the second member body 12, whereas in the second member body 23 of the second embodiment, the second member Rectangular windows 24 a and 24 b are provided at both ends of the main body 23. The vicinity of the concave portion 13 of the plate spring 11 that is cantilevered can be elastically deformed upward in the window 24a. Similarly, the vicinity of the convex portion 14 of the leaf spring 11 that is cantilevered can be elastically deformed upward in the window 24b. The configuration of the second member body 23 other than the windows 24a and 24b is the same as that of the second member body 12 of the first embodiment.
