Description

BACKGROUNDTechnical field

[0001] The present disclosure relates to a rotatable handheld tablet case. Description of the state of the art

[0002] Tablets are generally larger and heavier than mobile phones, so holding them for extended periods tends to cause fatigue. Tablet cases currently available on the market mainly include back cases, flip cases, and leather cases. However, a back case only covers the back and sides of the tablet and does not contribute to a better grip. While a flip case allows the tablet to be folded into a book-like shape, the back of the case must be folded when held, which increases its thickness and weight. A leather case is usually made of leather or synthetic materials that feel good and have a pleasant texture, but can slip when held.

[0003] It turns out that while existing protective cases can protect a tablet from scratches and bumps, they increase the thickness and weight of the tablet to a certain extent, making it harder to hold.

DETAILED DESCRIPTION

[0025] A variety of embodiments of the present disclosure will be described below with reference to the accompanying drawings. For clarity, many practical details are described together in the following description. However, it should be understood that these practical details should not be used to limit the present disclosure. That is, in some embodiments of the present disclosure, these practical details are not required. Furthermore, to simplify the accompanying drawings, some commonly used structures and components are illustrated in a simple schematic manner in the accompanying drawings.

[0026] It will be Fig. 1, Fig. 2 and Fig. 3. Fig. 1 is a perspective view of a rotatable handheld tablet case 100 according to an embodiment of the present disclosure. Fig. 2 is an exploded view of the rotatable handheld tablet case 100 of Fig. 1. Fig. 3 is another perspective view of the rotating handheld tablet case 100 in Fig. 1. As in Fig. 1 to Fig. 3, the rotatable handheld tablet case 100 in the present embodiment includes a fastening member 110, a holding member 120, a rotating member 130, and a protective cover 140. The holding member 130 is attached to the fastening member 110. The rotating member 130 is rotatably held between the fastening member 110 and the holding member 120. The protective cover 140 has a front surface and a rear surface 141 that are opposite to each other. The protective cover 140 is configured to be slid onto a tablet (not shown) at the front surface (e.g., the protective cover 140 engages an edge of the tablet). The rotating member 130 is attached to the rear surface 141. The holding member 120 is located between the rotating member 130 and the rear surface 141 of the protective cover 140.

[0027] From the above structural configurations, it can be seen that the protective cover 140 can be rotated relative to the fastening member 110 by the rotating member 130, which is attached to the back surface 141 of the protective cover 140 and is rotatably held between the fastening member 110 and the holding member 120, which are fastened to each other. In this way, the user can hold the tablet encased in the protective cover 140 by holding the fastening member 110 and can rotate the tablet to a desired rotational orientation. For example, the user can rotate the protective cover 140 relative to the fastening member 110 to a transverse rotational orientation, as shown in Fig. 1, or in a vertical rotational orientation, as shown in Fig. 3 shown, rotate.

[0028] As in Fig. 1, the rotatable handheld tablet case 100 in the present embodiment further comprises a plurality of fastening elements 171, 172. The fastening elements 171 are configured to pass through the protective case 140 from the front surface to be attached to fastening holes 137 of the rotating element 130 (see Fig. 5), whereby the protective cover 140 and the rotating element 130 are fastened to one another. In addition, the rotating element 130 has a continuous slot 132. The fastening elements 172 are configured such that they pass successively through the holding element 120 and the continuous slot 132 of the rotating element 130 from a side of the holding element 120 facing away from the fastening element 110 in order to be fastened to fastening holes 113 of the fastening element 110 (see Fig. 6), whereby the protective cover 140 and the rotating member 130 are fastened to each other. Although the fastening elements 171 in the present embodiment are exemplary screws, the disclosure is not limited thereto.

[0029] In some embodiments, the protective cover 140 and the rotating member 130 may be secured together by adhesive bonding. In some embodiments, the fastening member 110 and the retaining member 120 may be secured together via the through-slot 132 by adhesive bonding.

[0030] As in Fig. As shown in Figures 1 to 3, the rotatable handheld tablet case 100 in the present embodiment further includes a hand holder 150. The hand holder 150 is connected to the fastening member 110. In this way, the rotatable handheld tablet case 100 can use the hand holder 150 to assist in fixing the user's hand, allowing the user to more easily hold the tablet through the rotatable handheld tablet case 100.

[0031] As in Fig. As shown in Figures 1 to 3, the fastening member 110 in the present embodiment has two fastening holes 112. The two fastening holes 112 are located on two sides of the fastening member 110, respectively. Specifically, the hand holder 150 is an elastic band. Two ends of the hand holder 150 are respectively attached to the two fastening holes 112. In this way, a space for inserting the user's hand can be created between the fastening member 110 and the hand holder 150. The user only needs to insert their palm into this space to easily hold up the entire rotatable handheld tablet case 100.

[0032] It should be noted that the hand holder 150 is not limited to the shape of an elastic band. In some embodiments, the hand holder 150 may be shaped like a glove.

[0033] It will be Fig. 4, Fig. 5 and Fig. 6. Fig. 4 is a perspective view of the rotating member 130 according to an embodiment of the present disclosure. Fig. 5 is another perspective view of the rotary member 130 in Fig. 4. Fig. 6 is a perspective view of the fastener 110 according to an embodiment of the present disclosure. As shown in Fig. As shown in Figures 4 to 6, in the present embodiment, the fastening member 110 has a plurality of engagement grooves 111. The rotating member 130 includes a plurality of engagement blocks 135. Each of the engagement blocks 135 is configured to selectively engage one of the engagement grooves 111. In this way, the protective cover 140 can not only be temporarily stopped in a specific rotational orientation relative to the fastening member 110, but it can also provide the user with a sense of steps when rotating the protective cover 140.

[0034] As in Fig. 6, in the present embodiment, the number of engagement grooves 111 included in the rotating member 130 is 24. It can be seen that when one of the engagement blocks 135 moves from one of the engagement grooves 111 to another adjacent engagement groove 111, this means that the rotating member 130 rotates 15 degrees relative to the fixing member 110. However, the number of engagement blocks 135 included in the rotating member 130 is not limited to this embodiment and can be flexibly changed according to actual needs.

[0035] As in Fig. 4, in the present embodiment, the number of engagement blocks 135 is eight, but the present disclosure is not limited thereto and can be flexibly changed according to actual needs.

[0036] As especially in Fig. 2, Fig. 4 and Fig. 6, in the present embodiment, the rotary member 130 is configured to rotate about an axis A relative to the fastening member 110. The engaging grooves 111 are arranged annularly relative to the axis A. In other words, the distance between each of the engaging grooves 111 and the axis A is the same. During rotation of the rotary member 130 relative to the fastening member 110, each of the engaging blocks 135 performs a circular motion with the axis A as the center axis, and the path it travels passes through all of the engaging grooves 111 so that it can selectively engage with each of the engaging grooves 111.

[0037] As in Fig. 4, in the present embodiment, each of the engagement blocks 135 has a convex arc surface 135a. Each of the engagement blocks 135 contacts the engagement grooves 111 with its convex arc surface 135a. By using the convex arc surface 135a to contact the engagement grooves 111, the engagement blocks 135 can be smoothly separated from one of the engagement grooves 111 and move to another adjacent engagement groove 111 to re-engage.

[0038] In some embodiments, the convex arc surface 135a is part of a spherical surface, but the present disclosure is not so limited.

[0039] As in Fig. 4 and Fig. 5, the rotary member 130 in the present embodiment further includes a body portion 133 and a plurality of elastic arm portions 134. Each of the elastic arm portions 134 has a first end 134a and a second end 134b. The first end 134a is connected to the body portion 133. The engaging blocks 135 are provided at the second ends 134b of the elastic arm portions 134, respectively. By disposing the engaging blocks 135 on the elastic arm portions 134, each of the engaging blocks 135 can move smoothly between different engaging grooves 111.

[0040] As in Fig. 4 and Fig. As shown in Figure 5, the body portion 133 in the present embodiment has a plurality of holes 133a. The elastic arm portions 134 are located in the holes 133a and connected to inner edges of the holes 133a. The elastic arm portions 134 extend curvedly along an edge of the through-slot 132. That is, the elastic arm portions 134 extend curvedly around the axis A.

[0041] As in Fig. 4 and Fig. As shown in Figure 5, the body portion 133 in the present embodiment has a plurality of ribs 133b. Each of the ribs 133b separates two adjacent holes 133a from each other. Opposite sides of each of the ribs 133b are respectively connected to two of the elastic arm portions 134, and the two elastic arm portions 134 extend in opposite directions. With a variety of combinations of the rib 133b and the two symmetrically arranged elastic arm portions 134 annularly provided on the body portion 133 of the rotary member 130, the torques applied to the respective ribs 133b when the corresponding two of the elastic arm portions 134 are loaded can balance each other, thereby avoiding the deformation problem of the rotary member 130 after long-term use and effectively increasing the service life of the rotary member 130.

[0042] As in Fig. 4 and Fig. 5, the number of combinations of the rib 133b and the two symmetrically arranged elastic arm portions 134 is four in the present embodiment, but this disclosure is not limited thereto and can be flexibly changed according to actual needs.

[0043] It will be Fig. 7 and Fig. 8. Fig. Figure 7 is a schematic representation of some components of the rotating handheld tablet case 100 of Fig. 1. Fig. Figure 8 is another schematic representation of the components in Fig. 7. As in Fig. 1, Fig. 7 and Fig. As shown in Figure 8, the rotatable handheld tablet case 100 in the present embodiment further includes a lock 160. The lock 160 is slidably provided on the back 141 of the protective case 140. An edge of the holding member 120 includes a plurality of notches 121. The lock 160 is configured to selectively engage one of the notches 121.

[0044] As especially in Fig. 5, Fig. 7 and Fig. 8, in the present embodiment, the rotating member 130 has a recessed groove 131. The retaining member 120 is rotatably housed in the recessed groove 131. In this way, the retaining member 120 can rotate within the recessed groove 131 along an inner edge of the recessed groove 131. In addition, the rotating member 130 has a guide structure 136. The lock 160 is slidably engaged with the guide structure 136. The guide structure 136 is provided between the recessed groove 131 and an edge of the rotating member 130. In this way, the user can use the lock 160 to selectively engage one of the notches 121 on the edge of the retaining member 120, thereby uniquely positioning the protective cover 140 in a specific rotational orientation relative to the fastening member 110.

[0045] As in Fig. 7 and Fig. As shown in Figure 8, in the present embodiment, four notches 121 are provided on the holding element 120. It can be seen that when the lock 160 is pulled out of one of the notches 121 and inserted into another, adjacent notch 121, this means that the rotating element 130 rotates 90 degrees relative to the fastening element 110. For example, when the lock 160 is inserted into one of the notches 121, the protective cover 140 is in the position shown in Fig. 1 shown transverse rotational orientation relative to the fastening element 110. When the lock 160 is inserted into another, adjacent notch 121, the protective cover 140 is in a vertical rotational position relative to the fastening element 110, as in Fig. 3. However, the number of notches 121 provided by the holding member 120 is not limited to this embodiment and can be flexibly changed according to actual needs.

[0046] As in Fig. 5, Fig. 7 and Fig. As shown in Figure 8, the guide structure 136 in the present embodiment includes a plurality of hook portions 136a. The hook portions 136a are provided in an upper and lower row. The lock 160 can slide while held between the upper and lower rows of hook portions 136a, thereby sliding laterally relative to the rotary member 130. Furthermore, the hook portions 136a are engaged on a side of the lock 160 facing away from the rotary member 130 to prevent the lock 160 from being separated from the rotary member 130 in the forward direction.

[0047] According to the above embodiments of the disclosure, it can be seen that in the rotatable handheld tablet case of the present disclosure, since the rotating member attached to the back surface of the protective case is rotatably supported between the fastening member and the holding member, which are fastened to each other, the protective case can be rotated relative to the fastening member. In this way, a user can hold a tablet in the protective case by holding the fastening member (e.g., with a hand holder) and can rotate the tablet to a desired rotational orientation. By selectively engaging the engaging block of the rotating member with one of the engaging grooves of the fastening member, the protective case can not only be temporarily locked in a specific rotational orientation relative to the fastening member, but it can also provide the user with a sense of steps when rotating the protective case.By using the locking mechanism to selectively engage one of the notches on the edge of the retaining element, the protective cover can be uniquely positioned in a specific rotational orientation relative to the fastener.

[0048] Although the present disclosure is disclosed in the above-mentioned embodiments, the embodiments are not intended to limit the present disclosure. Anyone skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure. Therefore, the scope of the present disclosure is determined by the appended claims.
