The general principles defined in the following description would be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention.

(10) Referring to FIGS. 2 and 3 of the drawings, a waterproof racket according to a preferred embodiment of the present invention is illustrated, wherein the waterproof racket is embodied as a bouncing pad according to the present invention. The waterproof racket comprises a racket frame and a trampoline layer 10 supported by the racket frame.

(11) According to the preferred embodiment, the racket frame comprises an annular skeleton 20 and a receiving pocket 30 having a pocket cavity 301, wherein the annular skeleton 20 is received in the pocket cavity 301 to retain the receiving pocket 30 in an annular configuration. The receiving pocket 30 is made of waterproof material.

(12) Accordingly, the annular skeleton 20 is made of rigid material such as plastic or metal. The annular skeleton 20 can be configured to have different shapes and sizes, such as circular shape or oval shape. In one embodiment, the annular skeleton 20 is configured to have a circular shape as shown in FIGS. 1 and 2. When the annular skeleton 20 is received in the pocket cavity 301 of the receiving pocket 30, the shape of the receiving pocket 30 is retained by the annular skeleton 20. Preferably, the annular skeleton 20 is made of flexible material, wherein when the annular skeleton 20 is configured into a loop form, the annular skeleton 20 provides an outward and radial stretching force to provide a predetermined rigidity of the annular skeleton 20.

(13) The receiving pocket 30 comprises an outer sleeve 31 defining the pocket cavity 301 therein. As shown in FIG. 3, the outer sleeve 31 is constructed with multiple layers. In particular, the outer sleeve 31 comprises an outer waterproof layer 311, a cushioning layer 312, and an inner lining 313, wherein the cushioning layer 312 is adhered between the outer waterproof layer 311 and the inner lining 313.

(14) Accordingly, the outer sleeve 31 is folded to form the pocket cavity 301 therewithin. Two affixing edges of the outer sleeve 31 are affixed together to form an annular affixing brim 310 at an inner side of the outer sleeve 31 in order to form the pocket cavity 301 within the outer sleeve 31. It is worth mentioning that when the affixing edges of the outer sleeve 31 are affixed together, the outer sleeve 31 forms a tubular configuration to form the pocket cavity 301. A reinforcing layer 314 is provided to affix along the annular affixing brim 310 of the outer sleeve 31 to retain the attachment of the affixing edges of the outer sleeve 31. It is worth mentioning that the affixing edges of the outer sleeve 31 are affixed and overlappedly folded to form the annular affixing brim 310.

(15) As shown in FIG. 3, the peripheral edge 101 of the trampoline layer 10 is affixed to the annular affixing brim 310 of the outer sleeve 31 to retain the trampoline layer 10 within the inner peripheral of the receiving pocket 30. Furthermore, the reinforcing layer 314 is provided to affix along the annular affixing brim 310 of the outer sleeve 31 with the peripheral edge 101 of the trampoline layer 10 to ensure the attachment of the affixing edges of the outer sleeve 31 and the attachment of the peripheral edge of the trampoline layer 10 along the annular affixing brim 310 of the outer sleeve 31. Accordingly, the reinforcing layer 314 is half-folded to sandwich and affix to the annular affixing brim 310 of the outer sleeve 31 and the peripheral edge 101 of the trampoline layer 10. In other words, the reinforcing layer 314, having a U-shaped cross section, affixedly encloses the annular affixing brim 310 of the outer sleeve 31 and the peripheral edge 101 of the trampoline layer 10.

(16) According to the preferred embodiment, the trampoline layer 10 has at least a portion affixed to the receiving pocket 30, wherein the trampoline layer 10 is stretched to form a trampoline surface 11 in a tension manner. Preferably, the trampoline layer 10 is affixed to the receiving pocket 30 along a centerline thereof. The trampoline layer 10 is made of elastic material, wherein the trampoline layer 10 will provide a predetermined tension for catching or rebounding an object when the trampoline layer 10 is stretched. Accordingly, the trampoline surface 11 of the trampoline layer 10 has a planar configuration.

(17) Accordingly, the peripheral edge 101 of the trampoline layer 10 is affixed to an inner peripheral of the receiving pocket 30. The centerline of the receiving pocket 30 is defined by the trampoline layer 10 to form an upper half 302 of the receiving pocket 30 and a lower half 303 of the receiving pocket 30. In other words, the upper half 302 of the receiving pocket 30 above the trampoline layer 10 is symmetrical to the lower half 303 of the receiving pocket 30 below the trampoline layer 10 to enhance the handling of the waterproof racket.

(18) Therefore, the user is able to use either side of the racket frame to ensure the tension of the trampoline surface 11 of the trampoline layer 10. For example, when using the waterproof racket to play the racket sports by hitting a bouncy ball 50 with the trampoline layer 10, the tension of the trampoline surface 11 of the trampoline layer 10 for the forehand play is the same as the tension of the trampoline surface 11 of the trampoline layer 10 for the backhand play. It is worth mentioning that the user is able to grip a portion of the racket frame to hit the bouncy ball 50. Likewise, the waterproof racket can be embodied as a flying disc, such that the user is able to throw and catch the waterproof racket. It is worth mentioning that the flying disc will be bounced when the flying disc is thrown to hit on the ground, the wall, or any surface.

(19) As shown in FIGS. 4 and 5, a waterproof racket according to a second embodiment illustrates a modification of the first embodiment, wherein the receiving pocket 30 further comprises a cushioning element 32 received in the outer sleeve 31. The cushioning element 32 is preferably made of soft foaming material to provide a soft and cushioning feel for the receiving pocket 30. Preferably, the annular skeleton 20 is encirclingly wrapped by the cushioning element 32 to prevent the user directly contacting with the annular skeleton 20. In other words, the receiving pocket 30 is soft enough to provide a cushioning effect via the cushioning element 32 but is rigid enough to retain the shape of the receiving pocket 30 via the annular skeleton 10.

(20) The size of the pocket cavity 301 of the receiving pocket 30 is configured to fit the predetermined amount of cushioning element 32. In other words, in order to enhance the cushioning effect of the racket frame, the size of the pocket cavity 301 is increase to receive more amount of cushioning element 32. It is appreciated that the cushioning element 32 can be integrally formed with the cushioning layer 312. Therefore, the thickness of the cushioning layer 312 can be increased as integrating the cushioning element 32 with the cushioning layer 312 to enhance the cushioning effect of the racket frame.

(21) According to the preferred embodiment, the racket frame further comprises an elongated racket handle 40 extended from the annular skeleton 20 through the receiving pocket 30. Preferably, the racket handle 40 is coupled to the annular skeleton 20 via a handle connector 41. In one embodiment, the handle connector, having a T-shape, has a skeleton connecting portion and a handle connecting portion. The skeleton connecting portion of the handle connector is connected to a portion of the annular skeleton. One end of the racket handle 40 is connected to the handle connecting portion of the handle connector.

(22) It is appreciated that the racket handle 40 is detachably coupled to the handle connecting portion of the handle connector 41. For example, the racket handle 40 has a threaded end and the skeleton connecting portion of the handle connector 41 has a threaded slot, wherein the threaded end of the racket handle 40 is rotatably and detachably coupled with the threaded slot of the skeleton connecting portion of the handle connector 41. Therefore, the racket frame serves as a flying disc by detaching the racket handle 40 from the annular skeleton 20 and serves as a racket apparatus by attaching the racket handle 40 to the annular skeleton 20.

(23) As shown in FIG. 6, a waterproof racket according to a third embodiment illustrates a modification of the second embodiment, wherein the waterproof racket of the third embodiment has the same structural configuration except no cushioning element received in the outer sleeve 31. Therefore, the annular skeleton 20 is received in the outer sleeve 31 as shown in the first embodiment.

(24) FIGS. 7 and 8 illustrate a modification of the waterproof racket according to the above first to third embodiment, which can selectively adjust the tension of the trampoline layer 10. As shown in FIG. 7, the annular skeleton 20 comprises a plurality of skeleton arms 21 and a plurality of adjustable connectors 22 that connect the skeleton arms 21 end-to-end to selectively adjust an annular size of the annular skeleton 20. Accordingly, each of the skeleton arms 21 has two threaded end portions 211, wherein each of the adjustable connectors 22 has two side threaded opening slots 221 rotatably coupled with the threaded end portions 211 of two of the skeleton arms 21. Preferably, at least two skeleton arms 21 and two adjustable connectors 22 are provided to couple the skeleton arms 21 end-to-end to form the annular skeleton 20. Therefore, when the adjustable connector 22 is rotated at one direction, the threaded end portions 211 of the skeleton arms 21 are moved away from each other to enlarge the annular size of the annular skeleton 20. When the annular size of the annular skeleton 20 is enlarged, the receiving pocket 20 is stretched outwardly in a radial direction, such that the trampoline layer 10 is stretched correspondingly in a radial direction to increase the tension of the trampoline layer 10. When the adjustable connector 22 is rotated at an opposite direction, the threaded end portions 211 of the skeleton arms 21 are moved toward from each other to reduce the annular size of the annular skeleton 20. When the annular size of the annular skeleton 20 is reduced, the receiving pocket 20 has less stretch to reduce the tension of the trampoline layer 10.

(25) In order to allow the user to access the adjustable connectors 22, the receiving pocket 20 further comprises a foldable leaf 33 affixed to the outer sleeve 31 at an opening slit thereof to selectively enclose the pocket cavity 301. When the foldable leaf 33 is unfolded from the outer sleeve 31 to expose the pocket cavity 301, the user is able to rotate the adjustable connectors 22 to selectively adjust the annular size of the annular skeleton 20. When the foldable leaf 33 is folded on the outer sleeve 31, the opening slit of the outer sleeve 31 is covered to enclose the adjustable connectors 22 within the pocket cavity 301.

(26) Accordingly, the present invention further provides a manufacturing method of the waterproof racket, which comprises the following steps.

(30) (1.3) Optionally, receive the cushioning element 32 in the tubular outer sleeve 31 to form the receiving pocket 30.

(31) (2) Receive the annular skeleton 20 within the pocket cavity 301 of the receiving pocket 30 to retain the receiving pocket 30 in an annular configuration. Preferably, the annular skeleton 20 is encirclingly wrapped by the cushioning element 32.

(32) (3) Affix at least a portion of the trampoline layer 10 to the receiving pocket 20 along the centerline thereof, such that the trampoline layer 10 is stretched to form the trampoline surface 11 in a tension manner. In particularly, the peripheral edge of the trampoline layer 10 is affixed to the annular affixing brim 310 of the outer sleeve 31 to retain the trampoline layer 10 within the inner peripheral of the receiving pocket 20. Optionally, the reinforcing layer 314 is affixed to the annular affixing brim 310 of the outer sleeve 31 and the peripheral edge of the trampoline layer 10.

(33) (4) Optionally, couple the racket handle 40 at the annular skeleton through the receiving pocket 20. Accordingly, the step (4) further comprises the following steps.
