Abstract

A slider 4 slidable on a base 1 has a connecting piece 2 passing through elastic pieces 3 (e.g. springs 31,32), the elastic pieces 3 being between block pieces 12 on the base 1 and plates 42 on the slider 4 to force the slider back to a rest position. Sliding strips 41 of the slider 4 slide in chutes 11 of the base 1. Both springs can exert force at once, one compressed and one stretched, to restore the slider 4. Thus tactile feedback to a slider switch of an electronic device is improved.

Embodiment 1 FIG. 1 and FIG. 2 respectively illustrate an exploded diagram and an assembly finished product diagram of a sliding rail in this embodiment. Referring to FIG. 1 and FIG. 2, a sliding rail includes a base 1, a connecting piece 2, elastic pieces (elastically deformable elements) 3 and a slider 4. The sliding rail is of a rectangular structure and uses the base 1 and the slider 4 as a main body structure. The base I and the slider 4 are preferably subjected to an electroplating treatment, and thus have an electroplated layer one or more surfaces thereof The connecting piece 2 and the elastic pieces are accommodated in the base 1 and the slider 4. Correspondingly, the base 1 and the slider 4 also have a rectangular structure. Two long edges of the base 1 are bent upwards to form U-shaped sliding chutes 11 of a guide rail. Two short edges of the base 1 protrude upwards and are provided with a block piece 12, respectively. A mounting hole 121 is further provided on each of the block pieces 12. The mounting holes 121 on the two block pieces are located and aligned along the same straight line along which the connecting piece 2 is located.

In this embodiment, the connecting piece 2 is a shaft which is cylindrical, and which is used to position and guide the elastic pieces 3. Other cross-sectional shapes are also to be covered by this disclosure.

In order to combine with the base 1, a cross section, or footprint, of the slider 4 has a convex structure which corresponds to a cross section, or footprint, of the base 1. The slider 4 comprises two long outer edges, a sliding strip 41 which is arranged on each long outer edge, and plates 42 which extend, preferably by being bent, from a top of the slider 4 downwards. A through hole 421 is provided on the plates 42, respectively. The diameter of each through hole 421 is greater than the diameter of the cross section of the connecting piece 2, and is smaller than the diameter of the cross section of each elastic piece.

In this embodiment, the plates 42 extend, preferably by being bent, from the middle of the top of the slider 4 in a downward direction, and each respectively includes a left plate and a right plate (not labelled in the figure).

The elastic pieces 3 are positioned between the block pieces 12 of the base 1 and the plates 42 of the slider 4 when the slider 4 is engaged with the base 1. Corresponding to the left plate and the right plate of the slider 4. The elastic pieces include a first spring 31 on a left side and a second spring 32 on a right side of the centre of the slider 4.

In consideration of the connections between each component: the connecting piece 2 which is located within the slider 4, passes through the first spring 31 and the plates 42 (a left plate and a right plate) of the slider 4 in sequence, and the ends of the connecting piece 2 are fixedly mounted on the mounting holes 121 of the block pieces 12. Meanwhile, the sliding strips 41 of the slider 4 are accommodated, that is slideably located, in the sliding chutes 11, to and this is achieved by sliding the slider 4 on the base 1 along the sliding chutes 11. It is to be noted that the slider 4 is constructed such that it may respectively slide to the left end and the right end of the base 1 along the sliding chutes 11.

By pushing the slider 4 to slide to the right end of the base 1, when the slider 4 slides for a certain distance which means the slider 4 is not at the original, or rest, position, the second spring 32 is compressed; and after releasing the slider 4, the second spring 32 pushes, or induces, the slider to slide to the left and automatically back to an original position. By pushing the slider 4 to slide to the left end of the base 1, when the slider 4 slides for a certain distance which means the slider 4 is not at the original position, the first spring 31 is compressed; and after releasing the slider 4, the first spring 31 pushes the slider to slide to the right and automatically back to the original position. Of course, the system would also work by affixing the ends of the springs 31, 32 at their ends and stretching these when moving the slider 4; the stretched spring 31, 32 thus providing the restorative force to return to its rest length and moving the slider 4 and base 1 into the rest position. Both compressive and stretching forces of the springs 31, 32 (or elastic elements 3, if not springs) can be used simultaneously to provide the restorative force.

In this embodiment, the base 1 and the slider 4 are subjected to an electroplating treatment, so that an electroplating layer is formed on a surface of the slider and the base respectively. When the slider 4 slides to left and right on the base 1, because of the sliding connection between the sliding strips 41 and the sliding chutes 11, better smoothness in operation is obtained and noise in used is reduced.

According to the sliding rail in this embodiment, because the sliding rail is constructed with a small size, a smooth and stable sliding process, low noise and an adjustable sliding force and sliding stroke is obtained, the sliding rail of the present application effectively improves the user experience of the sliding operation on the sliding rail.

The above contents are merely examples and explanations for the structure of the utility model, and the description is specific and detailed but cannot be understood as a limit to the patent scope of the invention thereto. It is to be noted that those of ordinary skill in the art may further make a plurality of variations and improvements without departing from the concept of the invention and these obvious replacement forms all pertain to the protection scope of the invention which is defined by the claims.
