Description

11 propose {Dubois-type ergograph is intended to measure the health of the muscles of the test subject's fingers.

In FIG. 1 shows the front view of the ergograph; FIG. 2, rear view; FIG. 3 is a top view; FIG. 4 is a side view of the mechanism that drives the tablet with a sheet of paper; FIG. 5, 6 and. 7 - details.

The proposed ergograph (Figs. 1-4) consists of a vertically arranged carrier paper. A tablet, 1 and a spring 11 with a pencil TO, attached to the side of the bar 7. Planchette 1 is kept from falling using a cord thrown over the block: 2 and wound around the gate , 5 with a gear wheel 4.

Under the influence of the weight of the plate i, the gate tends to turn clockwise movement, but the plates 5 and the gates entering between the teeth interfere with this. These plates are placed on the surface of bar 7 with a load o, driven by a finger gripping the loop 9. The distance between the plates is equal to the one-and-a-half distance between the teeth of the wheel 4.

When bar 7 V is chamfering 1E ruzom to the extreme position, one tooth of wheel 4 rests on plate 5 (Fig. 5); when it is moved, caused by bending the finger, this tooth slips off the plate and is held on the right tooth adjacent to it, which engages the plate 6 (Fig. 6). When reverse movement of the bar 7, this prong gkgk kiv r r gvpyu ochrpel ,. for the plate 5, hook the teeth on the left (Fig. Tu. 1Thanks to this, with each movement of the bar back and forth, the gear wheel Rotates one distance between the teeth, as seen in Figs. 5 and 7. In connection with this, the tablet moves downwards, and the pencil at the next movement of the bar begins to draw at the new location. To wind the cord on the gate 8, it is rotated with a finger in the direction of the movement clockwise. At the same time the plate 5 is bent to the side (Fig. 5) and does not prevent the wheel from rotating in this direction. For the same so that this record is not about bending to the right, is trying to drive it about brad 12. Ipytuemy under tact metronome produces elevated term GRUAN until .ne tired. At this time, the pencil 10 draws parallel lines on the paper, force the slide at each finger at a certain distance D.

The subject is invented and. .

A Dubois-type ergograph consisting of a bar connected to a pencil and a test subject driven by a finger through a loop, characterized in that the tablet 7 carrying the paper is positioned vertically but is kept from falling using a cord thrown over block 2 and wound on a gate with a gear 4, pivoting each time the bar moves back and forth one distance between the teeth, due to the alternate stop of the plates 5 and 6 associated with bar 7, R plins FROM the teeth of the wheel 4.
