The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
Referring to FIG. 3, which is a perspective view showing a car-top tent according to the present invention mounted to the top of a car, the car, which is generally designate at 1, comprises a roof 11 in which a sunroof 10 is mounted. The car-top tent of the present invention, generally designated at 3, comprises a bottom base 32 that is mounted and fixed to the car roof 11 and a top cover 31 that, when not in use, is folded to overlap atop the bottom base 32. When the tent is put into use, a user may climb through the opening of the sunroof 10 to the car roof 11 and lift and turn the top cover 31 over to be substantially flush with the bottom base 32 and expand a sleep canopy 30 (as shown in FIG. 4).
Referring to FIG. 5, which shows a perspective view of the car-top tent 3 according to the present invention, the tent 3 is composed of a top cover 31 and a bottom base 32. The bottom base 32 is fixed to a roof of a car and is rotatably jointed to the top cover 31 by a pivot device 33 to allow the top cover 31 to be foldable with respect to the bottom base 32. The top cover 31 forms an opening 310, which, when the top cover 31 is opened to an operation position, corresponds in position to the sunroof of the car, and which is normally closed by a lid 312. The top of the top cover 31 also forms raised ribs 311, whereby when the top cover is opened, the ribs 311 are positioned against the car roof 11. The ribs 311 are respectively provided with centrally located resilient strips 3110, which realize tight engagement with the car roof 11 and ensure the top cover 31 be positioned substantially flush with the bottom base 32.
In use, as shown in FIG. 6, after the top cover 31 is opened, the sleep canopy 30 are connected to and supported by a plurality of support frames 34. Each support frame 34 is coupled to the pivot device 33, whereby when the top cover 31 is being opened, the support frames 34 are consecutively pulled open to eventually fully expand the sleep canopy 30. At this time, the sunroof 10 of the car is in alignment with the opening 310 of the top cover 31 (as shown in FIG. 7) to allow a user to move between the car and the tent by way through the sunroof 10 without getting off the car, which enhances personal safety of the user.
Further, a sleep mat 35 is arranged between the top cover 31 and the bottom base 32, as shown in FIG. 8. The bottom base 32 forms a recess 320 delimited by opposite side walls that form the pivot device 33. The sleep mat 35 is composed of a plurality of blocks that is separable from each other. One block 351 of the sleep mat 35 is received and retained in the recess 320 and another block 352 of the sleep mat 35 that is adjacent to the mat block 351 is angle adjustable by being selectively supported at a desired angle by a stop mechanism 350, whereby the mat block 352 can be set at any one of a plurality of different inclination angles. To set the mat block 352 horizontal, the mat block 352 is angularly moved forward to exceed a predetermined limit position, where the stop mechanism 350 is released to allow the mat block 352 to angularly move backward to the horizontal position.
To mount the car-top tent 3 to the car roof, with reference to FIGS. 8 and 10, the bottom base 32 is provided with mounting seats 36 on opposite side portions thereof and the bottom base 32 is further provided with position-adjusting members (not shown) that can hook the bottom base to the car respectively at front and rear ends and opposite sides for selective adjustment of the position of the bottom base 32 with respect to the car.
