Abstract

The utility model relates to a folding type tread mill training apparatus, which is composed of a handrail frame, a front main frame support, a rear main frame upright post, a main frame connecting rod, a pedal group and a resistance oil cylinder of a foot step, wherein, a first four connecting rod mechanism is formed by the handrail frame, the front main frame support, rear main frame upright post and the main frame connecting rod. A second four connecting rod mechanism is formed by the handrail frame, the pedal group, the pedal resistance oil cylinder and the rear main frame upright post. When the handrail frame is turned forwards or backwards, two connecting rod mechanisms are linked simultaneously. Thus the two connecting rod mechanisms are pulled close to a straight line to reach the purpose of folding. The utility model has the advantages of convenient operation and all folding can be achieved by one operation.

Description

The training aids but folding is marked time

But the utility model relates to a kind of folding training aids of marking time.

But the training aids of marking time in the market has can not folding and two kinds of foldings, and the training aids of wherein can not folding marking time can not folding occupy big collection space because of it, and also very inconvenience of carrying; Training aids then often causes operation inconvenience because of the folding step is various but folding is marked time.

But the purpose of this utility model is to design a kind of folding easy to use, simple to operate training aids of marking time.

The purpose of this utility model is achieved in that

The training aids but a kind of folding is marked time comprises:

One arm-rest frame, its lower end articulates by middle part and body frame rear column top are rotatable, and support, top turns pivot joint before lower end and the body frame, offers corresponding screw between above-mentioned two articulated sections and formed by a retaining screw to be spirally connected on arm-rest frame and body frame rear column; Support before one body frame; One body frame rear column; One body frame connecting rod, two ends movably are articulated near the position, centre of preceding support of body frame and body frame rear column respectively, constitute first quadric chain by support, body frame rear column, body frame connecting rod before above arm-rest frame, the body frame;

Two pedal groups, its front end and body frame rear column bottom are rotatable to articulate, and the middle part is rotatable respectively to be articulated in the two resistance oil cylinder lower ends of marking time; Two upper ends of marking time the resistance oil cylinder turn and are articulated in the preceding support, top of body frame, constitute second quadric chain by supporting before pedal group, mark time resistance oil cylinder, arm-rest frame and the body frame.

Owing to adopt two quadric chains, after screwing off retaining screw, when arm-rest frame rotate around body frame rear column top, drive support before the body frame, body frame connecting rod and first quadric chain is folded; Simultaneously, arm-rest frame folds second quadric chain and first quadric chain by the moving resistance oil cylinder of marking time of body frame front support strap, pedal group simultaneously.Promptly single stepping can be realized folding of the whole training aids of marking time after screwing off retaining screw, but has effect easy and simple to handle with respect to the mark time two step operations of training aids of original folding.

Following drawings and Examples are further described the utility model:

Fig. 1 is the stereogram of the utility model embodiment 1;

Fig. 2 is the side view of the utility model embodiment 1;

Fig. 3 is the stereogram of the utility model embodiment 2;

Fig. 4 is the stereogram of the utility model embodiment 3.

Referring to figs. 1 through Fig. 2 the utility model embodiment 1 is described as follows, the training aids but a kind of folding that this embodiment provides is marked time, comprise an arm-rest frame 1, its lower end is provided with hinge hole, top 21 rotatable pivot joints of a pair of lug 11 and body frame rear column 2 by middle position, lug 31 rotatable pivot joints of supporting 3 top before a hinge hole 12 and the body frame are established in its lower end, offer corresponding screw between two articulated sections 11 (21), 31 (12) and formed by a retaining screw 7 to be spirally connected on arm-rest frame 1 and body frame rear column 2.Support 3 before one body frame, its end cross bar 33 is in order to steadily to be put on the ground, and a pair of lug 31 and hinge hole, arm-rest frame lower end 12 rotatable pivot joints are established in its top, and hinge hole 41 rotatable pivot joints that a pair of lug 32 is used for connecting with body frame stalk 4 are established in vicinity in the middle of it.One body frame connecting rod 4, two ends are respectively established a hinge hole 41,42 and are supported 3 the lug 32 and lug 22 rotatable pivot joints of body frame rear column 2 respectively with before the body frame.One body frame rear column 2, its end cross bar 24 is in order to steadily to be put on the ground, lug 11 rotatable pivot joints of a hinge hole 21 and arm-rest frame are established on its top, hinge hole 42 rotatable pivot joints of a pair of lug 22 and body frame connecting rod 4 are established in its vicinity, middle part, a rotating shaft 23 is established in its lower end, in order to the rotatable pedal group 5 that articulates.Form first quadric chain by support 3 and body frame connecting rod 4 before above-mentioned arm-rest frame 1, body frame rear column 2, the body frame by four turning points 11 (21), 31 (12), 32 (41), 22 (42), when knob 7 screwed on, this first quadric chain formed the body frame that a firm triangle connects; And when screwing off knob 7 and turning over arm-rest frame 1, arm-rest frame turning point 12 supports 3 before driving body frames, drives body frame connecting rod 4 again first quadric chain is folded fully.Two pedal groups 5, its front end is established the rotating shaft 23 that a pair of hinge hole 51 movably is articulated in body frame rear column 2, a pair of lug 52 and the two resistance oil cylinder 6 rotatable pivot joints of marking time are respectively established in vicinity in the middle of it, and its tail end sets firmly a pair of pedal 53, and pin can steadily be stepped on pedal group 5.The two resistance oil cylinders 6 of marking time, its lower end is by lug 52 rotatable articulate of a pair of hinge hole 62 with pedal group 5, respectively establish a hinge hole 61 rotatable hinge axles 12 (31) that are articulated in preceding support 3 of body frame and arm-rest frame 1 on it and locate support formation second quadric chain before above-mentioned pedal group 5, the resistance oil cylinder 6 of marking time, arm-rest frame 1 and the body frame.When body frame fixedly the time, pedal group 5 constitutes complete marking time and instructs the device structure by hinge axle 51 and 12 (31) the rotatable body frames that are articulated in the resistance oil cylinder 6 of marking time.And when turning over arm-rest frame 1, arm-rest frame turning point 12 drives the resistance oil cylinder 6 of marking time and makes it to fold simultaneously with the body frame part with pedal group 5.

But embodiment 2 shown in Figure 3 provides the another kind folding training aids of marking time, the difference of itself and embodiment 1 is to replace supporting 3 before the body frame of embodiment 1 to support 8 before the first U-shaped body frame, its open end down, the movable body frame connecting rod 4 that articulates among the second U-shaped frame, the 9 replacement embodiment 1 therebetween, this second U-shaped frame 9 movably is articulated in the mid portion of body frame rear column 2 simultaneously.

But embodiment 3 shown in Figure 4 also provides a kind of folding training aids of marking time, and the difference of itself and embodiment 2 is that the connection of arm-rest frame 1 and body frame rear column 2 is by changing into dorsad towards pedal.
