1. Field of Invention
The present invention relates to an exercising apparatus, and more particularly to an exercising apparatus having a cushion and a shaft assembly for a user to exercise multiple parts of the user's body.
2. Description of the Related Art
An exercising apparatus usually has only one function to train a particular part of a user's body. For example, a resilient shaft that is bendable and is useful for exercising the user's body and has a central part and two ends. When the resilient shaft is used, a user holds the central part of the resilient shaft with hands and vibrates the resilient shaft up and down to exercise the arms. This resilient shaft has only one function, so the user usually feels boring and needs to spend much money to buy other exercising apparatuses. If an exercising apparatus with the resilient shaft has multiple functions, the user will need to buy only one exercising apparatus to exercise multiple parts of the user's body.
To overcome the shortcomings, the present invention provides a multifunctional exercising apparatus to mitigate or obviate the aforementioned.
The primary objective of the present invention is to provide an exercising apparatus for a user to exercise multiple parts of the user's body.
To achieve the objective, the exercising apparatus has a cushion, a shaft assembly and two adjusting devices. The cushion has two connecting bases respectively mounted on the cushion. The shaft assembly pivotally connects with the cushion and has a lateral shaft and two supporting shafts. The supporting shafts are resilient and bendable and each has two ends and a connecting cylinder. One end connects with a corresponding connecting base of the cushion and the other end connects with the lateral shaft. The connecting cylinder is hollow, is formed on one end of the supporting shaft, connects with the connecting base. Each adjusting device selectively fastens securely or pivots the connecting cylinder on the connecting base. The exercising apparatus allows a user to exercise multiple parts of a user's body.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The connecting bases (11) are respectively mounted on the sides of the cushion (10) and each connecting base (11) has an outside end and a protrusion (13). The outside end has a central part, an outer edge and a wind of cogs (12). The wind of cogs (12) is formed around the outer edge of the outside end. The protrusion (13) is formed on the central part of the connecting base (11) and has a central hole and a threaded sleeve (14). The central hole is defined in the protrusion (13). The threaded sleeve (14) is hollow, is securely mounted in the central hole in the protrusion (13) and has an inner surface and an inner thread. The inner thread is formed on the inner surface of the threaded sleeve (14).
The shaft assembly pivotally connects with the cushion (10) and has a lateral shaft (21) and two supporting shafts (22).
With further reference to
The supporting shafts (22) are resilient and bendable, correspond respectively to the connecting base (11) and each supporting shaft (22) has a proximal end, a distal end, a connecting cylinder (23) and a second connector.
The proximal end of the supporting shaft (22) connects with a corresponding connecting base (11) of the cushion (10) and the proximal end connects with a corresponding end of the lateral shaft (21).
The connecting cylinder (23) is hollow, is formed on the proximal end of the supporting shaft (22), connects with the corresponding connecting base (11) and has a through hole (232). The through hole (232) is defined through the connecting cylinder (23), receives the protrusion (13) of the corresponding connecting base (11) and has an outside open end and an inside open end. The inside open end allows the protrusion (13) to rotatably extend into the connecting cylinder (23) and has a connecting ring (231). The connecting ring (231) has a wind of cogs (233) corresponding to and selectively engage with or disengaging from the wind of the cogs (12) of the corresponding connecting base (11). The supporting shaft (22) may rotate when the winds of the cogs (12, 233) disengage from each other. The supporting shaft (22) is held at a desired angle between the cushion (10) and the supporting shaft (22) when the winds of the cogs (12, 233) engage with each other.
With further reference to FIGS. 5 to 7, the second connector is mounted on the distal end of the supporting shaft (22), detachably connects with a corresponding first connector of the lateral shaft (21) and may have a bracket (24), a rod (25), a spring (26), a button (27) and a nut (28).
The bracket (24) has a bottom, a top, a recess (241), a front wall and a rear wall. The bottom is mounted on the distal end of the supporting shaft (22) opposite to the connecting cylinder (23). The recess (241) is defined in the top of the bracket (24), communicates with the top and allows a corresponding hook (211) to be mounted in the recess (241). The front wall is formed in front of the recess (24) and has a front mounting hole and a receiving ring (242). The front mounting hole is formed through the front wall and communicates the recess (241). The receiving ring (242) is formed on the front, is around the front mounting hole of the front wall and has a non-circular inner edge. The rear wall is formed behind the recess (241) and has a rear mounting hole defined through the rear and corresponding to the front mounting hole of the front wall.
The rod (25) slidably extends through the front mounting hole of the front wall, the recess (241) and the rear mounting hole of the rear wall of the bracket (24), detachably engages with the engaging hole (212) in a corresponding hook (211) on the lateral shaft (21) and has a circular part, a narrowed part (252), a threaded protrusion (251) and a connecting protrusion (253). The circular part selectively engages with or disengages from the engaging hole (212) of the corresponding hook (212) in the recess (241). The circular part engages with the engaging hole (212) of the hook (211) when the rod (25) slides to a front position. The circular part disengages from the engaging hole (212) and extends through the rear mounting hole of the rear wall when the rod slides to a rear position. The circular part has a diameter. The diameter of the circular part corresponds to the dimension of the engaging hole (212) of the corresponding hook (211) and is greater than the width of the narrowed opening (213) of the corresponding hook (211). The narrowed part (252) is formed on the circular part and disengages from the engaging hole (212) when the circular part (251) engages with the engaging hole (212) of the corresponding hook (211) in the recess (241). The narrowed part (252) engaged with the engaging hole (212) and is aligned with the narrowed opening (213) of the corresponding hook (211) in the recess (241) when the circular part (251) disengages from the engaging hole (212). The narrowed part (252) has a width being smaller than the width of the narrowed part (213) of the hook (211). The threaded protrusion (251) longitudinally protrudes from the circular part of the rod (25), extends out of the rear mounting hole of the rear wall. The connecting protrusion (253) protrudes longitudinally from the narrowed part of the rod (25).
The spring (26) is mounted around the rod (25) and in the receiving ring (242).
The button (27) is mounted securely to the connecting protrusion (253), is mounted in the receiving ring (242) and allows the spring (26) to be mounted between the front wall and the button (27). The button (27) has a non-circular outer edge corresponding to the non-circular inner edge of the receiving ring (242) so the button (27) and the rod (25) can not rotate relative to the bracket (24). When the button (27) is not pushed, the narrowed part (252) on the rod (25) is mounted in the receiving ring (242) and the circular part (251) is mounted in the engaging hole (212) of the corresponding hook (211) in the recess (241). Therefore, the lateral shaft (21) securely connects with the supporting shaft (22). When the bottom (27) is pushed, the narrowed part (252) slides in the recess (241) and is aligned with the narrowed opening (213) in the corresponding hook (211) so the hook (211) disengages from the rod (25) and the lateral shaft (21) disengages from the supporting shaft (22). With the first and second connectors, the shaft assembly is assembled and disassembled easily.
The nut (28) is mounted around the threaded protrusion (251) to maintain the rod (25) in the bracket (24).
The adjusting device (30) are respectively mounted to the connecting cylinders (23). Each adjusting device (30) selectively fastens securely or pivots the connecting cylinder (23) of a corresponding supporting shaft (22) on the protrusion (13) of a corresponding connecting base (11). The adjusting device (30) selectively engages the wind of the cogs (12) of the connecting base (11) with the wind of the cogs of the connecting cylinder (23) or disengages the wind of the cogs (12) of the connecting base (11) from the wind of the cogs of the connecting cylinder (23). Each adjusting device (30) has an adjusting knob (32) and an extension rod (31). The adjusting knob (32) rotatably abuts the outside open end of the corresponding cylinder (23). The extension rod (31) is mounted on the adjusting knob (32), is mounted through the through hole (232) in the corresponding connecting cylinder (23) to the threaded sleeve (14) in the protrusion (13) of the corresponding connecting base (11) and has an outer surface and an outer thread. The outer thread is formed on the outer surface of the end, corresponds with and is screwed into the inner thread of the threaded sleeve (14).
