Abstract

The utility model relates to an adjustable rear bracing rod of a treadle mill. The treadle mill is provided with an armrest rack, a base and a running board, and the proper position of the bottom end of the running board, which is near to the rear side, is provided with an adjustable rear bracing rod; the support inclined angle of the running board is changed by the simple angle pivoting adjusting mode in order to simulate the running motion state on the flat or on the upslope. The utility model is characterized in that the rear bracing rod presents an n shape; one end of the rear bracing rod is provided with a pivoting part for pivoting with the corresponding position of the running board, and a bending rod is connected with the pivoting part; the bending point and the tail end of the bending rod are respectively provided with a first grounding tube and a second grounding tube; the first grounding tube or the second grounding tube is respectively supported on the ground by pivoting the pivot angle of the rear bracing rod and the running board; because of the angle difference between the two grounding tubes, the bracing inclined angle of the running board is effectively changed to achieve the prospective adjusting purpose.

Description

The adjustable rear pole of treadmill

Technical field

The utility model relates to a kind of adjustable rear pole of treadmill, is meant especially a kind ofly only must just can simulate the novel designs of level land or upward slope road-work state thus by easy angle pivot adjustment mode.

Background technology

Arbitrary treadmill all can be provided with in the running board appropriate location usually and can prop up element (comprising electronic or manual adjustment mechanism) for what adjust that running board props up angle, changed the support inclination angle of running board in good time, thereby produce so-called " running slope change ", and then the actual motion state of upper and lower slope of real simulation or level land running.

With regard to electronic guiding mechanism, it has the operation ease of certain degree really, but because being provided with of this mechanism will be improved manufacturing cost widely, also will inevitably cause no small consumption burden to the consumer, simultaneously, if this mechanism more can produce very big harmful effect to the user just in case there is fault to take place, and then its practicality that detracts.

Certainly, so-called manual adjustment type rear pole structural design is also arranged at present, but because its rear pole is divided into left and right two groups, and is hubbed at the both sides of the nearly rear side in running board bottom respectively, in brief, when adjusting, the user must adjust the rear pole of and arranged on left and right sides one by one to the same angle of propping up, and can finish the adjustment operation, therefore, though it has the economic benefit of expection, but additionally derive operational inconvenience.

Novel content

Because above-mentioned all, the purpose of this utility model provides a kind ofly only must just can simulate the adjustable rear pole of the treadmill of level land or upward slope road-work state by easy angle pivot adjustment mode thus.

The utility model is based on dual principles such as same economic benefit and operation ease, again do an effective and actual improvement at the rear pole element, so it mainly is П shape, the one end is an articulated section, for tying with the corresponding position pivot of running board, link a knee in this articulated section again, and at the inflection point and the end of this knee, be respectively equipped with first pipe and second pipe that contacts to earth that contacts to earth; Pivot knot angle by pivot this rear pole and running board is held in ground to make first or second tube stay that contacts to earth respectively, and because of this two differential seat angle that contacts to earth between pipe, and then effectively changes the support inclination angle of running board, reaches the simple and easy adjustment purpose of expection.

The specific embodiment

Certainly, for further understanding technological means of the present utility model and architectural feature, the conjunction with figs. detailed description is as follows:

At first, as shown in Figure 1, 2, be a preferred embodiment figure of the present utility model, as seen from the figure, this treadmill 10 includes arm-rest frame 12, base 14 and running board 16, in nearly rear side appropriate location, running board 16 bottoms, be provided with an adjustable rear pole 20, by easy angle pivot adjustment mode, with the support inclination angle of change running board 16, and then the motion state of the simulation level land or the running of going up a slope.

This rear pole 20 is П shape, and the one end is an articulated section 22, for the corresponding position pivot of running board 16 knot, link a knee 24 in this articulated section 22 again, and at the inflection point and the end of this knee 24, be respectively equipped with first pipe 26 and second pipe 28 that contacts to earth that contacts to earth; This rear pole 20 is tied angle with the pivot of running board 16 by pivoting, to make first or

second pipe

26,28 that contacts to earth prop up in ground 30 respectively, and because of this two differential seat angle of 26,28 of pipe that contacts to earth, and then effectively change the support inclination angle of running board 16, reach the adjustment purpose of expection.

As shown in Figure 3, for contacting to earth pipe 26 as the user mode schematic diagram that props up angle with first, at this moment, running board 16 will become heeling condition (the running state promptly goes up a slope), and shown in Figure 4, then for contacting to earth pipe 28 as the user mode schematic diagram that props up angle, at this moment with second, running board 16 will become parastate (being level land running state), so verified easily the design the practicality and the convenience of dark tool.

Claims

1. the adjustable rear pole of a treadmill, this treadmill has arm-rest frame, base and running board, be provided with an adjustable rear pole in nearly rear side appropriate location, running board bottom again, for the support inclination angle of adjusting running board, and then the motion state of the simulation level land or the running of going up a slope;

It is characterized in that: this rear pole is П shape, and the one end is an articulated section, with the corresponding position pivot of running board knot, links a knee in this articulated section again, and at the inflection point and the end of this knee, is respectively equipped with first pipe and second pipe that contacts to earth that contacts to earth.
