Abstract
Description
Technical Field
[0001] The utility model relates to a sports fitness exercise device, in particular to a fitness bike which can reduce the packaging volume. Background Art
[0002] Existing exercise bikes are all made based on the structural principles of traditional bicycles. Unlike traditional bicycles, these exercise bikes cannot be used on roads and can only imitate the motion pattern of bicycles in situ for competitors or bodybuilders to perform competitive sports or bodybuilding exercises, thereby achieving the purpose of competing or exercising. Exercise bikes on the market are generally large in size, resulting in large packaging volumes, which is inconvenient for product storage and transportation. In particular, for many home users with limited space, it is desirable to fold the exercise bike when not in use so that it only takes up a small amount of space. Although some existing exercise bikes can be folded, they have too many folding joints, making the folding speed very slow, and the structure is complex, and some require professional personnel to operate. Utility Model Content

[0043] The present invention is an exercise bike capable of reducing packaging volume. The front portion of the main beam 1 is equipped with a main frame 4, and the rear portion of the main beam 1 is equipped with a rear support frame 5; the rotating mechanism 6 and the damping mechanism 7 are installed in the main frame 4, and the seat cushion 10 is installed at the top end of the rear support frame 5; the main beam is disassembled into front and rear sections; and a first folding mechanism 8 is installed between the front and rear sections to enable the front section main beam 11 and the rear section main beam 12 to be extended and retracted forward and backward; a second folding mechanism 9 is installed between the front bottom support 2 and the rear bottom support 3 and the main beam 1, respectively, to enable the front bottom support 2 and the rear bottom support 3 to be rotated and folded toward the main beam 1. The structure of the present invention reduces the volume of the product in length and width by folding the front main beam 11 and the rear main beam 12 forward and backward and rotating and folding the front bottom support 2 and the rear bottom support 3 toward the main beam 1, thereby reducing the packaging volume of the product and eliminating the need to occupy a large space during transportation and storage, thereby facilitating transportation and storage of the product. In addition, the user can utilize the first folding mechanism 8 to extend and retract the front main beam 11 and the rear main beam 12 forward and backward to adjust the distance between the seat cushion 10 and the rotating mechanism 6 (i.e., the foot pedal), thereby making the product suitable for different groups of people.
[0044] The present invention provides an exercise bike capable of reducing packaging volume. The rear support frame is folded into two sections, upper and lower, by folding in five steps. A vertical telescopic mechanism is installed between the upper and lower rear support frames 51 and 52. This structure of the present invention reduces the height of the product through the vertical telescopic mechanism between the upper and lower rear support frames 51 and 52, further reducing the product's packaging volume. Furthermore, the height of the seat cushion 10 can be adjusted via the telescopic mechanism, making the product suitable for different groups of people.
[0045] The present invention provides an exercise bike capable of reducing packaging volume. The rear extension rod 82 is further connected to an adjustment rod 83.
