Description

Folding type exercise bicycle with single gripper shoe

The utility model relates to exercise bicycle, relate in particular to a kind of produce trample resistance, temper strength of one's legs, mechanism is foldable and do not occupy the folding type exercise bicycle with single gripper shoe of collection space.

General exercise bicycle because of simple in structure, volume is little and do not account for collection space, therefore has easy-to-use characteristic whenever and wherever possible, but general exercise bicycle is in order to save usage space, mostly the face of making of pedestal is designed to and takes on, so that the user sits center of gravity less stable when moving thereon with wide; In addition,, then need bigger collection space, the shortcoming of bringing easy-to-collection not and portably using by meeting if increase the volume and weight of bicycle integral body.Moreover also some exercise bicycle provides telescopic holding rod and seat cushion, but this kind mode only can partly stretch, and its holding rod that protrudes out can take up space equally, hinders collection.

The design people provides a kind of single gripper shoe that has because the collection of known exercise bicycle is difficult for and for the not good shortcoming of leg exercise, it is improved, and the exercise bicycle of being convenient to fold is to satisfy actual user's demand.

The purpose of this utility model is to provide a kind of folding type exercise bicycle with single gripper shoe, but the front support rod of its pedestal and main body are adopted the fixed form of hinge, can realize foldable fully when bicycle packing, transportation and collection; And the load device of this bicycle adopts single gripper shoe, effectively simplify member and form, and hold out against the blocking design by propelling sheave adjustable between load device and pedal unit, realize that the circle with load resistance on the way or without going out of one's way steps on motion, and mat mitigation control mode enhancement cardio-pulmonary function, promote healthy.

The purpose of this utility model can be achieved through the following technical solutions: a kind of folding type exercise bicycle with single gripper shoe, mainly include pedestal, bracing frame and load device, wherein, be installed with the bracing frame of tool front and back frame on the Base body, its rear support stand has the cushion of a scalable adjustment, the holding rod that pedal unit and comprises handle, the initiatively runner that is coupling on the pedal unit, this initiatively runner rotate with belt interlock driven pulley; It is characterized in that: described load device comprises driven pulley, cranks arm and propelling sheave, all be fixed on the Base body by the gripper shoe suspention, this crank pin is connected on the gripper shoe, changes the propelling sheave of belt elasticity tightness but this end of cranking arm is installed with the angle adjustment that mat cranks arm; The friction plate that combines around the control line that has under can be with adjusting via holding rod upper end that knob is connected on the described driven pulley; Be provided with the hinge that can make holding rod fold backward between described front support stand and the holding rod, but and pedestal front support rod is fixedlying connected of hinge with Base body.

Wherein, a described end of cranking arm is provided with that providing cranks arm and has the flexible member of elasticity tightness active force, and the angle control propelling sheave of cranking arm by adjustment changes belt elasticity tightness, adjusts the load forces of belt; When on the way or without going out of one's way stepping on action as foot-operated circle, on the driving wheel sheathed belt can drive driven pulley and rotate, can control the size that produces the resistance of loading by friction plate and propelling sheave therebetween, user's health can obtain step-type incremental motion amount, and can strengthen cardio-pulmonary function simultaneously, promote the health of health.

The utility model also can comprise following measure: the holding rod top is provided with a holding rod can make after foldable the handle of its upper end be adjusted the wing bolt that presses down; Wherein, mat L type frame fishplate bar articulates between pedestal and the front support rod, and this L type frame fishplate bar one side and main body be provided with axle sleeve and mutually winding be that can pivot fits to the main body place folds attitude.Be that front support rod can fold to the main body bending, to reduce shared horizontal space; And owing to be provided with a hinge between the holding rod of bracing frame and the bracing frame body, make the holding rod can be above the cushion after rear side is done horizontal folding and pressed on folding; In addition, the handle on the holding rod also simultaneously can press down adjustment, so then makes the utility model be close to and forms a square body.According to last, each position of mat can be and folds, flexible shape, makes shared space reach minimum.
