Abstract

The utility model discloses a bodybuilding cart. A driving piece arranged on a frame is provided with main shafts which are symmetrically arranged on the two sides of the frame in a stretching mode. A main gear, a swing arm, a planetary gear and a crank are arranged on the position, on two sides of the frame, of the main shaft. The planetary gears are driven to rotate through the cranks, and the swing arms drive the main shafts to rotate in a linkage mode. The planetary gears simultaneously move around the outer circumference of the main gears, and therefore treading pedals conduct circular movement around the axes of the planetary gears and form the track. By means of the bodybuilding cart, the axial track formed through feet treading changes a little instead of treading around a circle in the same axis, so that the range of the exercised muscle group is broadened, and the effect that more muscle portions are exercised can be achieved.

Detailed description of the invention

Refer to Fig. 1 to Fig. 7, person shown in figure is the selected example structure of the utility model, and this,, only for explanation, is not subject to the restriction of this kind of structure in patent application.

The present embodiment provides a kind of exercycle, and it comprises a vehicle frame 1, an actuator 2, two master gears 3, two swing arms 4, two planetary gears 5 and two cranks 6 as shown in Figure 1, wherein:

As shown in Figure 1, vehicle frame 1 is provided with pedestal 11, and pedestal 11 is provided with seat 12 and a handrail 13 in seat 12 fronts.

As shown in Figure 2, actuator 2 is established vehicle frame 1 and is had a pivotable main shaft 21, and main shaft 21 symmetries are stretched the both sides that are located at vehicle frame 1.In the present embodiment, actuator 2 comprises that a flying wheel 22 connects a passive runner 24 with a belt 23, and flying wheel 22 rotates under the load of passive runner 24.

As shown in Figure 2, two master gears 3 are coaxial with main shaft 21 and be fixed on the both sides of actuator 2 respectively, and main shaft 21 two ends pass two master gears 3.In the present embodiment, two master gears 3 are individually fixed in the both sides of flying wheel 22, and flying wheel 22 is coaxial and establish with two master gears 3.

As shown in Figure 2, two swing arms 4 are located at respectively the outside of two master gears 3 and are fixed in main shaft 21; Two planetary gears 5 are hubbed at respectively two swing arms 4, and as shown in Figure 3, two planetary gears 5 are all meshed with the master gear 3 of same swing arm 4; Two cranks 6 coaxially join at outside and the planetary gear 5 of respectively this swing arm 4 with one end respectively, and crank 6 is at the pedal 61 that is pivoted away from one end of planetary gear 5.

As shown in Figure 2, each planetary gear 5 of the present embodiment has a coaxial axostylus axostyle 51 and passes the outside of set swing arm 4, and axostylus axostyle 51 forms a bell and spigot joint 511 in the outside of set swing arm 4, this main shaft 21 also forms a bell and spigot joint 211 in the outside of set swing arm 4,6, each crank has a socket part 62 in the one end joining with corresponding planetary gear 4, and a socket can be selected at the bell and spigot joint 511 of the bell and spigot joint of main shaft 21 211 or axostylus axostyle 51 in socket part 62.

If select the socket part of two cranks 6 62 to be socketed in the bell and spigot joint 211 of main shaft 21, now when both feet, pedal 61 is trampled, just the track of two pedals 61 is as shown in Figure 4, along the axle center pitch of the laps of main shaft 21, now the obtainable effect of trampling is as known exercycle.

If select the socket part of two cranks 6 62 to be socketed in the bell and spigot joint 511 of two shaft lever 51, now when both feet are trampled pedal 61, two pedals 61 are taking axostylus axostyle 51 as axle center row circular motion, and because can driving planetary gear 5, crank 6 rotates, therefore planetary gear 5 as shown in Figure 5 along surrounding's pitch of the laps of master gear 3, causes the axostylus axostyle 51 of each planetary gear 5 as shown in Figure 6 taking main shaft 21 as axle center row circular motion.Under this pattern, user tramples two pedals 61 and taking axostylus axostyle 51 as axle center row circular motion time, axostylus axostyle 51 is also taking main shaft 21 as axle center row circular motion, therefore can make orbit of shaft center that both feet are trampled change to some extent but not trample around circle in same axle center, for the trample action of known exercycle, can make the muscle position that is moveable to more, and the trample action that differs from known exercycle also can make us producing feeling of freshness, be conducive to increase the number of times that sporter moves.
