The specific embodiment
As Fig. 2, shown in Figure 3, the back structure preferred embodiment of the utility model exercise and fitness equipment, these embodiment only for the usefulness of explanation, are not subjected to the restriction of this structure in patent application.Described chair back A is mounted on chair cushion 10 back side top of exercise and fitness equipment B1, and the exercise and fitness equipment B1 of present embodiment is a pedal body building vehicle; This chair back A includes chair back body 20 and winding frame 30, wherein, the bottom of this winding frame 30 has a group connecting part 31 and is positioned chair cushion 10 predetermined positions of exercise and fitness equipment B1 in order to winding, and the top of winding frame 30 then has the bolster portion 32 for chair back body 20 windings location; Improvement of the present utility model mainly is: this chair back body 20 comprises that being at least the first of left and right arranged spaced leans against portion 21 and second and lean against portion 22, and then constitutes a kind of two innovation structure kenels that lean against portion that have.
Wherein, this first, second lean against that group is provided with the adjustment structure between the bolster portion 32 of portion 21,22 and winding frame 30, in order to regulate and control this first, second lean against the spacing of portion 21,22; The adjustment structure of present embodiment comprises: (as shown in Figure 3, Figure 4)
One cunning with profile of tooth locating slot 41 is established and is held 40, is mounted on the bolster portion 32 of chair back A winding frame 30, and this profile of tooth locating slot 41 has several interval draw-in grooves 42 of establishing end 40 predetermined glide directions settings along sliding;
One guide sliding base 50, be mounted on first, second and lean against portion 21,22, this guide sliding base 50 tools one chute 51 just can be established end for aforementioned cunning and go into and be slidably state for 40 groups, and these guide sliding base 50 reservations hytes are provided with the positioning piece group and establish portion 52, and this keeper group is established establishing to being mutually vertical with the slide guide direction of the chute 51 of guide sliding base 50 of portion 52;
Positioning piece 60, the keeper group that is mounted on guide sliding base 50 is established portion 52, comprise a manipulation end 61 and a fastening end 62, wherein this manipulation end 61 can protrudingly be exposed a side of guide sliding base 50,62 of this fastening ends extend to the sliding profile of tooth locating slot 41 of establishing end 40, and are provided with a bayonet lock 63 in order in the draw-in groove 42 that is sticked in phase contraposition with it;
One elastic reset spare 70 is mounted on the opposite position of keeper 60, with so that the state that bayonet lock 63 normalities of this keeper 62 move towards the direction that is sticked in draw-in groove 42.
The use operational scenario of above-mentioned adjustment structure is as follows:
As shown in Figure 5, owing to be subjected to shoring of elastic reset spare 70 under these keeper 60 normalities, the bayonet lock 63 that impels this fastening end 62 is for snapping in the state of draw-in groove 42, with this will constitute this cunning and establish hold 40 be stuck and the positioning states that can't slide because the direction that can move of this keeper 60 is mutually vertically with the sliding end 40 of establishing this moment.
As shown in Figure 6, desire to make sliding establishing between end 40 and the guide sliding base 50 to be in the time of to adjust state, the user only must be exerted pressure by the manipulation end 61 of this keeper 60, can impel the bayonet lock 63 of this fastening end 62 to break away from draw-in groove 42, oppress elastic reset spare 70 simultaneously and accumulate elastic restoring force, can discharge the sliding end 40 of establishing this moment, constitute this cunning and establish the state that end 40 is slidably adjusted.
As shown in Figure 7, first, second of chair back A of the present utility model lean against portion 21,22 utilize above-mentioned adjustment structure operation and can be left and right relatively the state transferred of slippage, the wide cut that can adjust chair back A with this is required to adapt to the different users.
