In addition to the orientation depicted in the drawings, the relative spatial terms are also intended to cover different orientations of a device in use or operation. An apparatus may be orientated by other means (rotated by <NUM> degrees or having another orientation), and descriptive relative spatial terms used in the disclosure may also be similarly and correspondingly interpreted. It should be understood that, when an element is "connected to" or "coupled to" another element, the element may be directly connected or coupled to the another element, or the two may be interposed with an element.

Numerical ranges and parameters for describing general ranges of the present invention are approximate values, and the values given in the specific embodiments are reported as precisely as possible. However, some values inevitably contain certain errors caused by standard errors discovered in measured values of individual tests. Moreover, the term "about" or 'approximately" used in the disclosure usually means that a value is within ±<NUM>%, ±<NUM>%, ±<NUM>% or ±<NUM>% of a rated value or range. Therefore, it is generally considered by a person skilled in the art that the term "about" or "approximately" means that an average value is within an acceptable standard error. Apart from operation/working embodiments, or unless otherwise specified by other means, numerical ranges, quantities, values and percentages (for example, material quantities, durations, temperatures, operating conditions, ratios of quantity and the like) disclosed herein should be understood as modified by the term "about" or "approximately" in all circumstances. Thus, unless otherwise specified, the numerical parameters given in the present invention and the appended claims may be variable approximate values. At least, the numerical parameters should be understood according to the reported numerals of effective digits by common rounding means. A range may be represented in the disclosure as from one end point to another end point or between the two end points. Unless otherwise specified, all ranges disclosed herein are inclusive of the end points. The expression "substantially coplanar" may refer to two surfaces within several microns (µm) along the same plane (for example, within <NUM>, <NUM>, <NUM> or <NUM> along the same plane). When numerical values or features are "substantially" the same, the term may mean that the values are within ± <NUM>%, ±<NUM>%, ±<NUM>% or ±<NUM>% of an average value of the values.

An accessory for a handheld device is disclosed by the present invention to improve convenience for operating a handheld device for a user. The accessory may be attached to the handheld device or a case amounting to the handheld device, and includes a first base, a second base and two flexible elements. The two flexible elements are respectively disposed on two ends of the first base, and each of the flexible elements has a track. The second base has a fastener for engaging with the tracks of the two flexible elements. When a distance between the first base and the second base changes, the fastener slides along the tracks and the flexible elements are flexed.

More specifically, when the user increases the distance between the first base and the second base, the fastener slides relative to the tracks and a first deformation occurs to each of the flexible elements. When the fastener slides to an end point of the track, the respective first deformation of the flexible elements can maintain the distance between the first base and the second base. Accordingly, the user may place the handheld device at a specific orientation by using the accessory based on the first deformation of the flexible elements (as shown in <FIG>, in which A1 is the accessory and A2 is the handheld device). In contrast, when the user reduces the distance between the first base and the second base, the fastener slides relative to the tracks and a second deformation occurs to each of the flexible elements. The second deformation restores the flexible elements to the original state of the flexible elements from the first deformation.

Please refer to <FIG> shows a three-dimensional diagram of an accessory <NUM> according to some embodiments of the present invention. <FIG> shows another three-dimensional diagram of the accessory <NUM> according to some embodiments of the present invention. The accessory <NUM> includes a first base <NUM>, a second base <NUM>, a first flexible element <NUM> and a second flexible element <NUM>. The first flexible element <NUM> and the second flexible element <NUM> are respectively disposed at the first base <NUM>, and are located between the first base <NUM> and the second base <NUM>. The first flexible element <NUM> has a first track <NUM>. The second flexible element <NUM> has a second track <NUM>.

<FIG> shows a cross-sectional diagram of the accessory <NUM> taken along a section line A-A' in <FIG>. Specifically, the second base <NUM> has a fastener <NUM> for engaging with the first track <NUM> and the second track <NUM>, so that the first flexible element <NUM> and the second flexible element <NUM> may slide relative to the fastener <NUM>. The first flexible element <NUM> is flexed based on sliding of the fastener <NUM> along the first track <NUM>, and the second flexible element <NUM> is flexed based on sliding of the fastener <NUM> along the second track <NUM>.

Further, in these embodiments, the fastener <NUM> has a column-like trunk and a head. One end of the trunk is connected to a body of the second base <NUM>, another end of the trunk is connected to the head, and the trunk is located in the first track <NUM> and the second track <NUM>. An outer diameter of the head is greater than channel widths of the first track <NUM> and the second track <NUM>, so that the fastener <NUM> does not easily disengage from the first track <NUM> or the second track <NUM>.

<FIG> shows an operation schematic diagram of the accessory <NUM> according to some embodiments of the present invention. Specifically, when a distance between the first base <NUM> and the second base <NUM> increases (as shown by the arrows), the first base <NUM> pulls one end of the first flexible element <NUM> into motion. Since the fastener <NUM> of the second base <NUM> is engaged with the first track <NUM> of the first flexible element <NUM>, the fastener <NUM> slides along the first track <NUM> when one end of the first flexible element <NUM> moves with the first base <NUM>. As the fastener <NUM> slides to one end of the first track <NUM>, as shown in <FIG>, a deformation occurs to the first flexible element <NUM>, and such deformation can maintain a distance between one end of the first base <NUM> and one end of the second base <NUM>.

<FIG> shows another operation schematic diagram of the accessory <NUM> according to some embodiments of the present invention. In contrast to the above-described operation, when the distance between the first base <NUM> and the second base <NUM> decreases (as shown by the arrows), the first base <NUM> pushes one end of the first flexible element <NUM> into motion. Since the fastener <NUM> of the second base <NUM> is engaged with the first track <NUM> of the first flexible element <NUM>, the fastener <NUM> slides along the first track <NUM> when one end of the first flexible element <NUM> moves with the first base <NUM>. When the fastener <NUM> slides to another end of the first track <NUM>, a deformation occurs to the first flexible element <NUM> for restoring the first flexible element <NUM> to its original state.

Similarly, when the distance between the first base <NUM> and the second base <NUM> increases, the first base <NUM> pulls one end of the second flexible element <NUM> into motion. Since the fastener <NUM> of the second base <NUM> is engaged with the second track <NUM> of the second flexible element <NUM>, the fastener <NUM> slides along the second track <NUM> when one end of the second flexible element <NUM> moves with the first base <NUM>. As the fastener <NUM> slides to one end of the second track <NUM>, as shown in <FIG>, a deformation occurs to the second flexible element <NUM>, and such deformation can maintain a distance between another end of the first base <NUM> and another end of the second base <NUM>.

In contrast, when the distance between the first base <NUM> and the second base <NUM> decreases, the first base <NUM> pushes one end of the second flexible element <NUM> into motion. Since the fastener <NUM> of the second base <NUM> is engaged with the second track <NUM> of the second flexible element <NUM>, the fastener <NUM> slides along the second track <NUM> when one end of the second flexible element <NUM> moves with the first base <NUM>. Accordingly, a deformation occurs to the second flexible element <NUM> for restoring the second flexible element <NUM> to its original state.

Referring to <FIG>, in another embodiment, a fastener <NUM>' may be a long structure, and has a trunk and a head. The trunk and the head are both long structures, and the trunk is located in the first track <NUM> and the second track <NUM>. An outer diameter of the head is greater than channel widths of the first track <NUM> and the second track <NUM>, so that the fastener <NUM>' does not easily disengage from the first track <NUM> or the second track <NUM>. Moreover, because the fastener <NUM>' and the hollow-shaped tracks are both long structures, the fastener <NUM>' can retain the first flexible element <NUM> and the second flexible element <NUM> from swaying or deviating relative to the fastener <NUM>'.

As such, as shown in <FIG>, the first fastener 95P protruding in the direction toward the baffle <NUM> abuts against the baffle <NUM> on a side of the baffle <NUM>, so as to prevent the first flexible element <NUM> from departing the space <NUM>.

Specifically, when the distance between the first base <NUM> and the second base <NUM> increases (as shown by the arrows), the first base <NUM> pulls one end of the first flexible element 105B into motion. Since the first flexible element 105B passes through the space <NUM> defined by the baffle <NUM> and the base body <NUM>, as one end of the first flexible element 105B moves with the first base <NUM>, a deformation occurs to the first flexible element 105B as shown in <FIG>, and such deformation can maintain a distance between one end of the first base <NUM> and one end of the second base <NUM>.

Please also refer to <FIG>, which shows another operation schematic diagram of the accessory <NUM> according to some embodiments of the present invention. In contrast to the above-described operation, when the distance between the first base <NUM> and the second base <NUM> decreases (as shown by the arrows), the first base <NUM> pushes one end of the first flexible element 105B into motion. Since the first flexible element 105B passes through the space <NUM> defined by the baffle <NUM> and the base body <NUM>, a deformation occurs to the first flexible element 105B for restoring the first flexible element 105B to its original state when one end of the first flexible element 105B moves with the first base <NUM>.

Similarly, when the distance between the first base <NUM> and the second base <NUM> increases, the first base <NUM> pulls one end of the second flexible element 105C into motion. Since the second flexible element 105C passes through the space <NUM> defined by the baffle <NUM> and the base body <NUM>, as one end of the second flexible element 105C moves with the first base <NUM>, a deformation occurs to the second flexible element 105C as shown in <FIG>, and such deformation can maintain the distance between one end of the first base <NUM> and one end of the second base <NUM>.

In contrast, when the distance between the first base <NUM> and the second base <NUM> decreases, the first base <NUM> pushes one end of the second flexible element 105C into motion. Since the second flexible element 105C passes through the space <NUM> defined by the baffle <NUM> and the base body <NUM>, a deformation occurs to the second flexible element 105C for restoring the second flexible element 105C to its original state when one end of the second flexible element 105C moves with the first base <NUM>.

In some embodiments, the support body 105A, the first flexible element 105B and the second flexible element 105C may be independent components. In some embodiments, the support body 105A, the first flexible element 105B and the second flexible element 105C may be integrally formed.

In some embodiments, as shown in <FIG>, the support assembly further includes a first connecting element 105D and a second connecting element 105E.
