    DETAILED DESCRIPTION OF PREFERRED EMBODIMENTSThe drawing figures thus illustrate a device 1 for measuring the tensile force ofthe fingers of one hand. The device 1 comprises a stand 2 and one suspended in the standmeasuring means 3. The lighting means 3 comprises in its most general embodiment a holder 4 in the form ofone with the measuring means in a suspended position substantially vertically extending waist part 4a and two withbody part connected and substantially perpendicular from the same extending legs 4b and4c, so that a space is delimited between the legs. The measuring means 3 includes at mostgeneral design in addition at least in the space between the legs 4b, 4c extending, ithe legs stored and by the fingers of a hand placed in the space, when stretchingthe fingers, actuable measuring piece 5 and at least one in and / or at the joint between the body part 4aand resp. leg 4b or 4c arranged sensor 6 for measuring the force with whichthe fingers when stretching affect the measuring piece.
    The frame 2 shown in the embodiment is formed with a support part 2a and a suspension part 2b formeasuring means 3. The support part 2a has a portion 2c against which the arm of the person whosefinger tensile forces shall be measured at rest. In order to get as optimal a measurement result as possible, isthe measuring means 3 designed hanging freely in a suspension means 7 in the frame 2, i.e. inthe suspension part 2b of the stand. This suspension member 7, e.g. a wire or a spring,and the design of the stand 2 with the portion 2c against which the arm is to rest, causes the arm101520253035PM30153SEOO 3in the correct position, force components along the forearm are removed and no loadson the hand that can affect the measurement result occurs.
    The holder 4 of the measuring member 3 comprises, as stated above, a waist part 4a and two legs4b, 4c which are connected to the body part, e.g. welded to the body or designed in onepiece with this, and which extends substantially perpendicularly from the part of the body. Legs 4b, 4cruns in the same direction and delimits a space for e.g. measuring piece 5. Thisspace is thus delimited on three sides by the life part 4a resp. of the legs 4b and 4c, butis open to the fourth side. The body part 4a and resp. leg 4b or 4c forms at the connectionthen between them a joint, which in the shown embodiment is linear. The sensor 6 which is arrangedin and / or at this joint for measuring the force with which the fingers when stretchingaffects the measuring piece, in the embodiment shown is also substantially linear.Although in the embodiment shown in the drawing figures only one sensor 6 is arranged onthe inside of the body 4a in and / or at the joint between the body and resp. leg 4b or 4cfor measuring the force with which the fingers when stretching actuate the measuring piece 5, canat least one sensor is arranged on each side of the joint between the body part and resp. leg,i.e. that at least two sensors 6 are found at each joint between the web part 4a and resp.leg 4b or 4c. One sensor 6 is then found on the web part 4a and the other sensor6 on the leg 4b or 4c. The sensors 6, which are then also substantially linear, runthereby e.g. substantially in the longitudinal direction of the joint and substantially parallel to each other.
    According to the invention, at least one sensor 8 for measuring the force with which the fingers canwhen stretched, the measuring piece 5 also acts on the outside of the web part 4a of the holder4. In the embodiment shown in the drawing figures, however, two sensors 8 are arranged onthe outside of the waist part 4a to the holder 4. For optimal measurement results and to compensate forany shear movements in the material of the measuring device, these sensors 8 are therearranged substantially opposite the sensors 6 on the inside of the web part in and / or at the jointbetween the body 4a and resp. leg 4b or 4c. These sensors 8 are also mainlyelongated and run substantially parallel to each other and with the sensors 6 onthe inside of the living part 4a. The sensors 8 can, however, be of any type suitable for the stated purposeand / or have any other form suitable for this purpose than substantially elongate. The sensors8, as well as the sensors 6 in and / or at the joints between the body part 4a and resp. leg 4bor 4c, however, consists of e.g. wire strain gauges, as sensors of this type shownthemselves work perfectly for absorbing the force from fingers which, when stretched, are pressed101520253035PM30153SEOO 4against the measuring piece 5. The sensors 6, 8 are in the shown version glued in place, but can alsoattached in another suitable manner.
    For optimal measurement results, the measuring piece 5 is arranged so that at least the intermediate onesthe phalanges of the fingers of the hand on which the force of the fingers is to be measured during stretching,comes into abutment against the measuring piece when the hand is placed in the space between the legs4b, 4c to the holder 4. The transfer of the tensile force of the fingers from that of the legs 4b, 4cstored the measuring piece 5 to the sensors on the body part 4a resp. on each side of the joint betweenthe body part and resp. leg 4b or 4c, then takes place in the best way.
    As can be seen from the drawing figures, the measuring means 3 can, in addition to the above-mentioned componentsalso comprise at least one extending in the space between the legs 4b, 4c to the holder 4, inthe legs stored control piece 9 for adapting the measuring means to the size of an ithe space placed hand on which the force of the fingers when stretching is to be measured. Regulatoryparagraph 9 is then arranged so that the hand on which the force of the fingers is to be stretchedcan be gripped, can grip the control piece when the hand is placed in the space between the legsthe holder. The control piece 9 causes the control to be slidably arranged in the legs 4b, 4c so thatthe hand can be inserted between the control piece and the waist part 4a to the holder 4 and placed so thatat least the intermedial phalanxes on the fingers of the hand come into contact withthe measuring piece. Displacement is achieved in a simple manner by storing the control piece 9 inone in resp. leg-shaped long hole 10. The long holes 10 then extend substantially at right angles inin relation to the longitudinal extent of the waist part 4a.
    By being able to grasp the control piece 9, the same is according to a further embodiment ofthe invention is designed for measuring also the gripping force on one in the space between the legshand placed to the holder. The control piece 9 can for this purpose comprise two gripping portionsand at least one sensor 11 arranged between the gripping portions for measuring the gripping force throughcompressing the gripping portions against the sensor using it in the space betweenthe legs 4b, 4c to the holder 4 placed the hand. The sensor 11 for measuring a handgripping force consists of e.g. a wire strain gauge, as well as the sensors 6, 8 described above,but may, like these, be of any other suitable type and exhibit any other suitableform. The sensor 11 is shown only schematically with dashed lines in Figs. 1 and 4.
    As can be seen from the drawing figures, the measuring means 3 can, in addition to the above-mentioned componentsand the above-mentioned control piece 9 also comprise at least one in the space between the legs 4b,101520253035PM30153SEOO 54c to the holder 4 extending, support piece 12 stored in the legs for support of one in the spaceplaced hand on which the force of the fingers when stretching is to be measured. The support piece 12 isarranged so that the back of the hand on the hand on which the force of the fingers when stretching shouldmeasured, comes into abutment against the support piece when the hand is placed in the space betweenthe legs 4b, 4c to the holder 4.
    In addition to the long holes 10 for storing the control piece 9 in the legs 4b, 4c, the legs havealso holes 13 resp. 14 for storing the measuring pieces and support pieces 5, 12 therein. Because measuring andthe support pieces 5, 12 do not have to be adjustable, the holes for these in the legs 4b,4c also not be long holes. However, it can be an advantage if measurement, regulation and supportthe pieces 5, 9, 12 are detachably mounted in the legs 4b, 4c to allow replacement if necessaryhence. For example, for this purpose, the measuring, regulating and support pieces 5, 9, 12 can be designedwith holes extending in the same longitudinal direction for through shafts 15, 16 resp. 17 somat the ends are stored in the legs 4b, 4c, and where at least one end of resp. axel kandesigned, e.g. provided with a thread to screw on the thread on e.g. a knob or anut to hold the measuring, regulating and support pieces in place or even tighten the knobsalternatively the nuts against the legs for clamping the measuring, regulating and support pieces inintended location. In designs without the need to be able to replace the mentioned measuring, control andsupport pieces 5, 9, 12, the through shafts 15, 16, 17 do not need to be designed according toabove. However, the control piece 9 must be designed e.g. as above or in any other appropriate way sothat the same can be loosened and after displacement thereof in the long hole 10 clamped in the desiredlocation.
    The legs 4b, 4c of the holder 4 are formed in the embodiment shown in the drawing figureseach a recess 21 and a groove 22 in the side 21a of the recess which is locatedclosest to the holder part 4a of the holder. The recess 21 can have any suitable shape, but the side21a with the groove 22 should be relatively close to the web part 4a. Track 22, which is directed insubstantially perpendicular to the web part 4a, is found in the embodiment shown in the drawing figures inside 21a of the recess 21 substantially opposite the sensors 6, 8 on resp. side of the waist,since the forces on the holder 4, when stretching the fingers, are thereby forced out towards the sensor.rerna. Optimal control of the forces towards the correct points on the holder 4 is thus achieved.
    The web part 4a of the holder 4 can according to a suitable further embodiment of the device 1 according tothe present invention have at least one opening 18 for controlling the locationof a hand in the space between the legs 4b, 4c to the holder, as this is important for101520253035PM30153SEOO 6to achieve optimal power distribution and comparable measurement results. The opening 18 is for thispurpose arranged so that when correctly placing the hand in the space between the legs 4b,4c, the proximal or first phalanx is found after the knuckles on the hand opposite said oneopening. This implicitly means that said opening 18 is located substantially opposite the regulationparagraph 9. In the embodiment shown in the drawing figures, two openings 18 are found in the web part 4ato the holder 4.
    To show the results of measurements of the force the fingers of a hand develop during stretchingfingers so that the fingers are pressed against the measuring piece 5 in the measuring device 1 according tothe device, according to a further embodiment, also comprises a display 19 which isconnected to the measuring means 3, i.e. with the sensors 6, 8 and 11, in the best way, eitherwirelessly or via a physical connection of some kind. The display 19 can be arranged onthe stand 2 or on the measuring means 3, e.g. on the waist part 4a of the holder 4, or lie next to the measuringthe device 1. The measurement results can also be displayed in e.g. a computer connected to the display16 alternatively is connected directly to the sensors 6, 8, 11 in a suitable manner. Desired measurementsvalues for the entire measurement period are thus obtained directly and can e.g. quickly compared withprevious measurement values for the patient in question.
    The device 1 according to the invention is by its design suitable for measuring fingerprints.the tensile force of both the right and left hand. The only action that needs to be takenfor measuring the tensile force of the fingers on both hands is that after loosening the measuring devicenet 3 from its suspension in the suspension means 7 in the frame 2, facing the measuring meansso that the measuring means is hung up in the wire in the stand via the opposite leg 4b or 4c on the holder4. Resp. leg 4b or 4c on the holder 4 has for this purpose a suitable bracket 20for the suspension member 7, e.g. a hole for the wire or spring.
    The above-described embodiment of the device according to the present invention makes it easier toachieve the same measurement conditions with repeated measurements with one and the same patient andthis regardless of whether it is a question of left or right hand. By the deviceis easy to assemble and disassemble or the stand is collapsible, the device is easy tobring wherever there is a need.
    It will be apparent to those skilled in the art that the device of the present invention canmodified and modified within the scope of the appended claims without departing from the invention.one's idea and purpose. Thus, e.g. the stand 2 is designed in a different way than the one10PM30153SEOO 7appears from the drawing figures. The measuring means 3 and the various components included therein are alsocan be designed in other ways than those shown in the attached drawing figures. Lifeline 4a andin particular the legs 4b, 4c of the holder 4 can thus be designed with, for example, one morepronounced three- or four-sided shape, but with recess 21 and groove 22 therein retained inthe legs. Also those measuring, regulating and in the space between the legs 4b, 4cthe support pieces 5, 9, 12 can thus be designed differently. Although the lattercomponents in the shown embodiment are of wood and other parts of the device of metal, canThe choice of materials also varies according to needs and wishes. For example. know the componentsmade of plastic or of combinations of different materials.
