FIG. 2 to FIG. 4 are assembly diagrams of the supporting device 1 in different applications according to the embodiment of the present invention. The supporting device 1 includes at least two supporting components 11, 12, and a joint mechanism 3. The supporting device 1 further includes a seat component 2 detachably connected to the joint mechanism 3, such as an infant basket, a crib, a baby chair, a child safety seat, and so on. The joint mechanism 3 is connected to the at least two supporting components 11, 12. The joint mechanism 3 includes a first joint component 31, a second joint component 32, a triggering component 33 and a resilient component 34. The first joint component 31 is connected to one of the at least two supporting components 11 and 12, the second joint component 32 is connected to the other of the at least two supporting components 11, 12 and pivoted to the first joint component 31. According to this embodiment, the first joint component 31 is connected to the supporting component 11, and second joint component 32 is connected to the supporting component 12. The triggering component 33 is movably connected to the first joint component 31 for selectively engaging with or separating from the second joint component 32.
Please refer to FIG. 5 and FIG. 6. FIG. 5 and FIG. 6 are exploded diagrams of the joint mechanism 3 in different views according to the embodiment of the present invention. The joint mechanism 3 includes a first leg 312a and a second leg 322a. The first leg 312a is connected to one of the at least two supporting components 11, 12 and the first joint component 31. The second leg 322a is connected to the other of the at least two supporting components 11, 12 and the second joint component 32. According to this embodiment, the first leg 312a is connected to the support component 11 and the first joint component 31, and the second leg 322a is connected to the support component 12 and the second joint component 32.
Furthermore, the first joint component 31 includes a first plate 311 and a first sidewall 312 vertically connected to a periphery of the first plate 311. The second joint component 32 includes a second plate 321 and a second sidewall 322 vertically connected to a periphery of the second plate 322 and pivotally connected to the first sidewall 312. The triggering component 33 is movably connected to the first plate 311 for selectively engaging with or separating from the second sidewall 322. In general, the first leg 312a is connected to the first sidewall 312, and the second leg 322a is connected to the second sidewall 322. Alternatively, the first leg 312a also can be connected to the first plate 311, and the second leg 322a also can be connected to second plate 321.
To achieve that the triggering component 33 can be movably connected to the first plate 311, a sliding slot 313 is disposed on the first plate 311, and the triggering component 33 includes a sliding block 331 slidably installed inside the sliding slot 313. The sliding block 331 is surrounded by the first plate 311, the first sidewall 312, the second plate 321 and the second sidewall 322, and the sliding block 331 is contained inside the first joint component 31 and the second joint component 32, so as to prevent interference in the sliding block 331 from the outside as the sliding block 331 is slidably installed inside the sliding slot 313, resulting in enhanced protection and stability. In addition, an opening 314 is formed on the first sidewall 312 and communicated with the sliding slot 313. The triggering component 33 includes a button 332 passing through the opening 314, and at least one part of the button 332 is exposed out of the first joint component 31 and the second joint component 32. A user can easily operate the button 332 for pushing the sliding block 331 to move the triggering component 33 outside the first joint component 31 and the second component 32.
Please refer to FIG. 1, FIG. 5 and FIG. 6. A main sunken portion 323 is formed on the second sidewall 322, the triggering component 33 includes a main protrusion 333 for selectively engaging with or separating from the main sunken portion 323. The at least two supporting components 11, 12 move away from each other for unfolding the supporting device 1 as the main protrusion 333 is engaged with the main sunken portion 323. In addition, a main concave portion 324 is formed on the second sidewall 322 for selectively engaging with or separating from the main protrusion 323. The at least two supporting components 11, 12 move close to each other for folding the supporting device 1 as the main protrusion 323 is engaged with the main concave portion 324. The above structural design can provide enough structural strength to ensure the supporting device 1 not to loose and be unfolded.
Please refer to FIG. 1, FIG. 7 and FIG. 8. FIG. 7 and FIG. 8 are different partial exploded diagrams of the joint mechanism 3 according to the embodiment of the present invention. An inclined surface 324a is formed on an inner surface of the main concave portion 324 close to the main sunken portion 323. A vertical surface 324b is formed on an inner surface of the main concave portion 324 away from the main sunken portion 323. A depth of the main concave portion 324 is less than a depth of the main sunken portion 323. As the at least two supporting components 11, 12 move close to each other until the main protrusion 333 engages with the main concave portion 324 so as to fold the supporting device 1, the vertical surface 324b is to prevent the at least two supporting components 11, 12 from moving too close so that the supporting device 1 is not able to stand stably. As moving the at least two supporting components 11, 12 away from each other for unfolding the supporting device 1, it only applies less force for separating the at least two supporting components 11, 12 and it is not necessary to press the triggering component 33 because the main protrusion 333 is easy to detach from the main concave portion 324 due to the less depth of the main concave portion 324 and the inclined surface 324a. 
In addition, a constraining slot 325 is disposed on the second sidewall 322, the first joint component 31 further includes a constraining block 315 connected to the first sidewall 312 and slidably installed inside the constraining slot 325. A movement of the pivoting between the first joint component 31 and the second component 32 is constrained by the engagement of the constraining block 315 and the constraining slot 325. For example, the first joint component 31 and the second joint component 32 mutually pivot for moving the at least two components 11, 12 close to or far way from each other as the main protrusion 333 separates from the main sunken portion 323 or the main concave portion 324. The engagement of the constraining block 315 and the constraining slot 325 is to prevent the at least two supporting components 11, 12 from moving too close or too far away from each other. Besides, the engagement of the constraining block 315 and the constraining slot 325 enhances the engagement of the main protrusion 333 with the main sunken portion 323 or the main concave portion 324.
For strengthening the pivotal connection between the first joint component 31 and the second joint component 32, the first joint 31 further includes a pivoting shaft 316 connected to a center of the first plate 311, and the second joint component 32 further includes a pivoting pillar 326 connected to a center of the second plate 321 and pivotally connected to the pivoting shaft 316. Preferably, a pivoting hole 327 is formed on the pivoting pillar 326, and the pivoting shaft 316 is pivotally installed inside the pivoting hole 327.
Please refer to FIG. 1, FIG. 9 and FIG. 10. FIG. 9 is a cross-section diagram of the joint mechanism 3 according to the embodiment of the present invention. FIG. 10 is a partial cross-section diagram of the joint mechanism 3 according to the embodiment of the present invention. For strengthening the engagement of the first joint component 31 and the second joint component 32, an auxiliary sunken portion 328 is formed on the pivoting pillar 326, and the triggering component 33 includes an auxiliary protrusion 334 for selectively engaging with or separating from the auxiliary sunken portion 328. The at least two supporting components 11, 12 move away from each other for unfolding the supporting device 1 as the auxiliary protrusion 334 is engaged with the auxiliary sunken portion 328. In addition, an auxiliary concave portion 329 is formed on the pivoting pillar 326 for selectively engaging with or separating from the auxiliary protrusion 334. The at least two supporting components 11, 12 move close to each other for folding the supporting device 1 as the auxiliary protrusion 334 is engaged with the auxiliary concave portion 329.
Furthermore, an inclined surface 329a is formed on an inner surface of the auxiliary concave portion 329 close to the auxiliary sunken portion 328. A vertical surface 329b is formed on an inner surface of the auxiliary concave portion 329 far away from the auxiliary sunken portion 328. A depth of the auxiliary concave portion 329 is less than a depth of the auxiliary sunken portion 328. The engagement of the auxiliary protrusion 334 with the auxiliary sunken portion 328 or the auxiliary concave portion 329 is as same as the engagement of the main protrusion 333 with the main sunken portion 323 or the main concave portion 324, and detailed description is not reiterated.
Please refer to FIG. 10 and FIG. 11. FIG. 11 is another cross-section diagram of the joint mechanism 3 according to the embodiment of the present invention. The joint mechanism 3 further includes a resilient component 34 disposed between the first joint component 31 and the triggering component 33 for resiliently contacting with the first joint component 31 and the triggering component 33. The resilient component 34 is resiliently connected with the pivoting shaft 316 and the sliding block 331. Accordingly, the resilient component 34 pushes the sliding block 331 toward the first sidewall 312 to strengthen the engagement. The main protrusion 333 can continuously engage with the main sunken portion 323 or the main concave portion 328, and the auxiliary protrusion 334 can continuously engage with the auxiliary sunken portion 324 or the auxiliary concave portion 329 by disposing the resilient component 34 between the first joint component 31 and the triggering component 33. In addition, the resilient component 34 can push the triggering component 33 after the button 332 is pressed, so that a user does not have to pull up the button 332 to recover the button 332.
In contrast to the prior art, the joint mechanism and the supporting device therewith can effectively fold or unfold the supporting components easily and conveniently.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
