[0089] The following disclosure provides many different embodiments or examples for implementing the different features of the provided subject matter. The specific examples of components and configurations are described below to simplify the present invention. Of course, these components and configurations are only examples and are not intended to be restrictive. In the present invention, the following description mentions that the first feature is formed above or on the second feature and may include an embodiment in which the first feature and the second feature are directly contacted, and may also include an embodiment in which additional features may be formed between the first feature and the second feature so that the first feature and the second feature may not be directly contacted. In addition, the present invention may repeat the figure numbers and / or letters in various examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or configurations discussed.

[0090] Embodiments of the present invention are discussed in more detail below. However, it should be understood that the present invention provides many applicable concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative and do not limit the scope of the present invention.

[0091] In addition, for ease of description, spatially relative terms such as "under," "below," "above," "upper," "lower," "left," "right," and the like may be used herein to describe the relationship of one element or feature to another (or multiple) element or feature as illustrated in the drawings. In addition to the orientation depicted in the drawings, spatially relative terms are intended to cover different orientations of the device in use or operation. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein may be interpreted accordingly. It should be understood that when an element is referred to as being "connected to" or "coupled to" another element, the element may be directly connected to or coupled to the other element, or there may be intervening elements.

[0092] The numerical ranges and parameters describing the broad scope of the present invention are approximate values, and the numerical values ​​described in the specific examples can be reported as accurately as possible. However, some numerical values ​​may contain certain errors that are necessarily caused by the standard deviation found in the individual test measurements. In addition, as used herein, the term "about" generally means within ±10%, ±5%, ±1% or ±0.5% of a given value or range. Alternatively, it is generally believed by those skilled in the art that the term "about" means within the acceptable standard error of the mean value. Except in the operation / working examples, or unless otherwise explicitly specified, all of the numerical ranges, amounts, values ​​and percentages (such as, the amount of materials disclosed herein, duration, temperature, operating conditions, ratios of amounts and the like) should be understood to be modified by the term "about" in all cases. Therefore, unless otherwise indicated, the numerical parameters described in the present invention and claims are variable approximate values. At least, each numerical parameter should be understood according to the number of reported significant figures and by applying general rounding techniques. The range can be expressed as from one endpoint to another or between two endpoints in this article. Unless otherwise specified, all ranges disclosed herein are inclusive. The term "substantially coplanar" may refer to two surfaces that are within a few micrometers (μm) along the same plane, such as within 10 μm, within 5 μm, within 1 μm, or within 0.5 μm along the same plane. When values ​​or properties are referred to as being "substantially" the same, the term may refer to the values ​​being within ±10%, ±5%, ±1%, or ±0.5% of the average of the values.

[0093] The present invention discloses an accessory for a handheld device, which is used to increase the convenience of a user in operating the handheld device. The accessory can be attached to the handheld device or a housing for the handheld device, and includes a first base, a second base, and two flexible elements. The two flexible elements are respectively arranged at two ends of the first base, and each flexible element has a track. The second base has a fastener for engaging the tracks of the two flexible elements. When the distance between the first base and the second base changes, the fastener slides along the track and the flexible element is deformed.

[0094] More specifically, when the user increases the distance between the first base and the second base, the fastener slides relative to the track and each flexible element undergoes a first deformation. When the fastener slides to the end point of the track, the first deformation of each flexible element can maintain the distance between the first base and the second base. Thus, the user can use the accessory to place the handheld device in a specific posture (such as Fig.11 In the figure, A1 is an accessory and A2 is a handheld device). On the other hand, when the user shortens the distance between the first base and the second base, the fastener slides relative to the track and each flexible element undergoes a second deformation. The second deformation includes a deformation from the first deformation to the original state of the flexible element.

[0095] See also Figure 1A and Figure 1B . Figure 1A It is a three-dimensional diagram of an accessory 1 according to some embodiments of the present invention. Figure 1B 1 is another three-dimensional view of an accessory 1 according to some embodiments of the present invention. The accessory 1 comprises a first base 11, a second base 13, a first flexible element 15 and a second flexible element 17. The first flexible element 15 and the second flexible element 17 are respectively disposed on the first base 11 and between the first base 11 and the second base 13. The first flexible element 15 has a first track 151. The second flexible element 17 has a second track 171.

[0096] Please also read Figure 1C , which is Figure 1B 1 is a cross-sectional view of the accessory 1 along the tangent line A-A'. Specifically, the second base 13 has a fastener 131 for engaging the first track 151 and the second track 171, so that the first flexible element 15 and the second flexible element 17 can slide relative to the fastener. The first flexible element 15 is deformed based on the sliding of the fastener 131 along the first track 151, and the second flexible element 17 is deformed based on the sliding of the fastener 131 along the second track 171.

[0097] Furthermore, in these embodiments, the fastener 131 has a columnar body and a head, one end of the body is connected to the main body, and the other end is connected to the head, the body is located in the first track 151 and the second track 171, and the outer diameter of the head is greater than the groove width of the first track 151 and the second track 171, so that the fastener is not easy to fall off from the first track 151 and the second track 171.

[0098] Please refer to Figure 1D, which is a schematic diagram of the operation of the accessory 1 of some embodiments of the present invention. In detail, when the distance between the first base 11 and the second base 13 increases (as shown by the arrow direction), the first base 11 drives one end of the first flexible element 15 to move, and because the fastener 131 of the second base 13 engages the first track 151 of the first flexible element 15, when one end of the first flexible element 15 moves with the first base 11, the fastener 131 slides along the first track 151. When the fastener 131 slides to one end of the first track 151, as shown in FIG. Figure 1B As shown, the first flexible element 15 generates a bending deformation, and the deformation can maintain the distance between one end of the first base 11 and one end of the second base 13 .

[0099] Please refer to Figure 1E , which is another operation schematic diagram of the accessory 1 of some embodiments of the present invention. On the other hand, when the distance between the first base 11 and the second base 13 decreases (as shown by the arrow direction), the first base 11 drives one end of the first flexible element 15 to displace, and because the fastener 131 of the second base 13 engages the first track 151 of the first flexible element 15, when one end of the first flexible element 15 displaces with the first base 11, the fastener 131 slides along the first track 151. When the fastener 131 slides to the other end of the first track 151, the first flexible element 15 is deformed to return to its original state.

[0100] Similarly, when the distance between the first base 11 and the second base 13 increases, the first base 11 drives one end of the second flexible element 17 to move, and because the fastener 131 of the second base 13 engages the second track 171 of the second flexible element 17, when one end of the second flexible element 17 moves with the first base 11, the fastener 131 slides along the second track 171. When the fastener 131 slides to one end of the second track 171, as shown in FIG. Figure 1B As shown, the second flexible element 17 generates a bending deformation, and this deformation can maintain the distance between the other end of the first base 11 and the other end of the second base 13 .

[0101] On the other hand, when the distance between the first base 11 and the second base 13 decreases, the first base 11 drives one end of the second flexible element 17 to be displaced, and since the fastener 131 of the second base 13 engages the second track 171 of the second flexible element 17, when one end of the second flexible element 17 is displaced along with the first base 11, the fastener 131 slides along the second track 171. Accordingly, the second flexible element 17 is deformed to return to its original state.

[0102] See also Figure 1FIn other embodiments, the fastener 131' may be an elongated structure and have a body and a head, the body and the head are also elongated structures, the body is located in the first track 151 and the second track 171, and the outer diameter of the head is greater than the groove width of the first track 151 and the second track 171, so that the fastener 131' is not easy to fall off from the first track 151 and the second track 171. In addition, since the fastener 131' and the hollow shape of the track are both elongated structures, the fastener 131' can limit the first flexible element 15 and the second flexible element 17 from swinging relative to the fastener 131'.

[0103] See also Figure 2A and Figure 2B . Figure 2A It is a three-dimensional diagram of an accessory 2 according to some embodiments of the present invention.

The accessory 2 includes a first base 21 , a second base 23 , a first flexible element 25 and a second flexible element 27 .

[0104] Specifically, the first base 21 and the second base 23 include an elongated structure. In these embodiments, the two long sides of the elongated structure of the second base 23 each have an inner recess 237. In other embodiments, the two long sides of the elongated structure of the first base 21 each have an inner recess, or the two long sides of the elongated structures of the first base 21 and the second base 23 each have an inner recess, or one long side of the elongated structure of the first base 21 and the second base 23 has an inner recess, and the design of the inner recess facilitates the clamping operation of the user. The first flexible element 25 and the second flexible element 27 include a sheet structure, which is disposed on the first base 21 and between the first base 21 and the second base 23. The first flexible element 25 has a first track 251, and the second flexible element 27 has a second track 271.

[0105] One end of the first flexible element 25 is disposed at one end 210 of the first base 21, and one end of the second flexible element 27 is disposed at one end 212 of the first base 21. The second base 23 has an accommodating space 230. When the first base 21 and the second base 23 are adjacent, the first flexible element 25 and the second flexible element 27 are placed in the accommodating space 230.

Specifically, the second base 23 has a fastener 231, a main body 233, two side walls 234 and a baffle 235. The two side walls 234 are spaced apart and disposed at the top of the main body 233 and together with the main body 233 form a receiving space 230. The baffle 235 bridges the two side walls 234 and defines a space 232 with the main body 233. The fastener 231 is disposed on the baffle 235 in the space 232 for engaging the first track 251 and the second track 271.

[0107] In these embodiments, the first track 251 includes a hollow portion formed in the first flexible element 25, the second track 271 includes a hollow portion formed in the second flexible element 27, and the first flexible element 25 and the second flexible element 27 are overlapped with each other and penetrate the space 232. The fastener 231 passes through the hollow portion of the first flexible element 25 and the hollow portion of the second flexible element 27 to join the first track 251 and the second track 271. The first flexible element 25 is deformed based on the sliding of the fastener 231 along the first track 251, and the second flexible element 27 is deformed based on the sliding of the fastener 231 along the second track 271.

In detail, when the distance between the first base 21 and the second base 23 increases (as shown by the arrow direction), the first base 21 drives one end of the first flexible element 25 to move, and because the fastener 231 of the second base 23 engages the first track 251 of the first flexible element 25, when one end of the first flexible element 25 moves with the first base 21, the fastener 231 slides along the first track 251. When the fastener 231 slides to one end of the first track 251, as shown in FIG. Figure 2B As shown, the first flexible element 25 generates a bending deformation, and the deformation can maintain the distance between one end of the first base 21 and one end of the second base 23 .

[0109] Please refer to Figure 2E , which is another operation schematic diagram of the accessory 2 of some embodiments of the present invention.

Figure 2B As shown, the second flexible element 27 generates a bending deformation, and this deformation can maintain the distance between the other end of the first base 21 and the other end of the second base 23 .

[0111] On the other hand, when the distance between the first base 21 and the second base 23 decreases, the first base 21 drives one end of the second flexible element 27 to be displaced, and since the fastener 231 of the second base 23 engages the second track 271 of the second flexible element 27, when one end of the second flexible element 27 is displaced along with the first base 21, the fastener 231 slides along the second track 271. Accordingly, the second flexible element 27 is deformed to return to its original state.

The first flexible element 75 and the second flexible element 77 are deformed based on the change in the distance between the first base 71 and the second base 73.

[0150] Please refer to Fig.7D , which is a schematic diagram of the operation of the accessory 7 of some embodiments of the present invention. Specifically, when the distance between the first base 71 and the second base 73 increases (as shown by the arrow direction), the first base 71 drives one end of the first flexible element 75 to move, and because the first flexible element 75 passes through the space 732A defined by the baffle 735A and the baffle 735B, when one end of the first flexible element 75 moves with the first base 71, as shown in FIG. Figure 7B As shown, the first flexible element 75 generates a bending deformation, and this deformation can maintain the distance between one end of the first base 71 and one end of the second base 73 .

[0152] Similarly, when the distance between the first base 71 and the second base 73 increases, the first base 71 drives one end of the second flexible element 77 to move. Since the second flexible element 77 passes through the space 732B defined by the baffle 735B and the main body 733, when one end of the second flexible element 77 moves with the first base 71, Figure 7B As shown, the second flexible element 77 generates a bending deformation, and this deformation can maintain the distance between one end of the first base 71 and one end of the second base 73 .

[0153] On the other hand, when the distance between the first base 71 and the second base 73 decreases, the first base 71 drives one end of the second flexible element 77 to be displaced. Since the second flexible element 77 passes through the space 732B defined by the baffle 735B and the main body 733, when one end of the second flexible element 77 is displaced along with the first base 71, the second flexible element 77 is deformed to return to its original state.

[0154] In some embodiments, please refer to Figure 7FThe first flexible element 75 has a stopper structure 751 at one end passing through the space 732A. When the distance between the first base 71 and the second base 73 increases, the stopper structure 751 is used to abut against the baffle 735A to prevent the first flexible element 75 from escaping from the space 732A. Similarly, the second flexible element 77 has a stopper structure (not shown) at one end passing through the space 732B to abut against the baffle 735B to prevent the second flexible element 77 from escaping from the space 732B.
