Definitions
- the present invention relates to a device for measuring a displacement (initial position and stroke) intended to be used in particular in a sports exercise or rehabilitation device of the type in which the key makes it possible to select a part of the available weight stack and provided with a transmitter system and moves in parallel with a receiver system, which converts the signal emitted by the key into an electrical signal processed by an electronic system connected to the receiver.
- the transmitter is positioned on the mobile part, called a slide, ensuring the guiding in translation of the selected load.
- the present invention is characterized in that the transmitter is placed in the key.
- This key allows the user to make integral part of the stack of weight of the selector that the user moves vertically by a transmission system from the point of application of his effort.
- the advantage of this invention compared to the state of the existing techniques lies in the fact that one can directly know the value of the load lifted by the user.
- the present invention is also characterized in that the receiving system is composed of a succession of identical detectors, regularly spaced.
- the transmitting key moving along this transmitting system one can know the position of the key, at time t, during the movement of the user, by identifying the detectors which receive the transmitted signal. All the characteristic values (stroke, speed, acceleration, etc.) of the movement can be deduced from this measurement, an internal clock being managed by the electronic signal processing system and delivering information on the times relating to the movement.
- the advantage of the invention- in view of the prior art lies in the knowledge of representative values of the effort of the user (provided work power output) calculated from the measured values (load, displacement ).
- FIG. 1 schematically shows a perspective view of the main mechanical elements of the device.
- FIG. 2 schematically shows a perspective view of the same elements as in Figure 1 but with traction applied by the user.
- FIG. 3 shows a top view of the transmitter / receiver assembly.
- FIG. 4 represents a side view of the transmitter / receiver assembly in the same position, taken for example, as in FIG. 2.
- FIG. 5 shows schematically a view of the connection of electronic elements.
- FIG. 1 represents a schematic view of the main mechanical elements, taken in the rest state, that is to say when the user applies no force to the point of application (4).
- the assembly capable of being moved vertically along the axis (5), the mobile assembly, is at its lowest point, a function performed by the chassis (21).
- This mobile assembly consists of the stack of weights (2), itself made up of a known number of identical counterweights (1), the key (10), the selector (23) and the selector rod (7). ), not shown here because it crosses right through each of the counterweights (I) of the stack (2) along the axis (5).
- This assembly is guided in vertical translation by a guide device (22), for example consisting of 2 cylindrical tubes on which slides the selector (23).
- Figure 2 shows the same elements as Figure 1 but in a position different from the low point position.
- the non-limiting example illustrated here shows that from a tensile force by the user to the point (4) on the transmission element (8), the movable assembly is moved vertically according to the axis (5).
- the traction of the user is shown by way of example along a horizontal axis at point (4), but that its direction depends on the movement executed by the user. This movement is determined by the type of exercise equipment that can be connected to the device, shown in the In FIG.
- the example shows that four counterweights (1) are made integral with the selector (23) by the rod (7) of this same selector, which rod is traversed right through, through an orifice ( 9) by a key (10) on which the four counterweights (1) are supported. These four counterweights were selected in the rest state by means of the key (10) from among the counterweights (1) of the stack (2).
- the selected counterweights constitute the part of the weight stack (3).
- This device is not limited in number of counterweights (1) constituting the stack (2), nor is it limited in number of counterweights (1) constituting the part of the stack (3).
- this device is not limited neither to the type of guide device (22), nor to the shape of the key (10), nor to the method of attachment between the key (10) and the rod (7). , or even the shape of the counterweights (1).
- Figure 2 shows that the key (10) is moved vertically along the axis (5), and that one of these ends is close to the support (15).
- the subsequent description of the transmitter / receiver system will show how the position of the key can be known at all times. It can be known from its initial position (18), and at any point of its displacement along the axis (5).
- FIG 3 shows a top view of the transmitter / receiver system.
- the transmitter consists of the key (10) which comprises at its 1st end (11) a gripping element and at its 2nd end (12) a magnet (14).
- Figure 3 shows that the key (10) passes through a counterweight (1) right through the groove (36) and also cross right through the rod (7), which rod (7) passes through the counterweight (1) through the opening (6).
- the user selects at the low point position (see Fig. 1) the desired number of counterweights which will constitute the part of the stack (3) which he will move.
- the fact that the transmitter is produced by the key (10) makes it possible to know the initial position (18) thereof, and therefore the number of counterweights selected by the user.
- This receiver system consists of detectors (16) fixed and electrically connected to a module (19).
- the modules (19) are fixed to the rigid part (20) of the support (15).
- Figure 3 shows that the detectors (16) are placed in a plane substantially parallel to the axis (13) of the key (10).
- the detectors (16) are located in the magnetic field of the magnet (14). This arrangement ensures detection by one or more detectors (16) of the proximity of the magnet (14) whatever the depth position of the key (10) along its own axis (13).
- Figure 4 shows a side view of the transmitter / receiver system. This view shows, by way of nonlimiting example, the mobile assembly in a position different from the
- the magnet (14) housed at the end (12) of the key (10), actuates the detectors (31) which are located in the magnetic field it generates , and does not activate the detectors (32) which are not in this magnetic field.
- This device is not limited to a total number of detectors (16), or the number of actuated sensors (31) simultaneously by the magnet (14). At the terminals of each detector
- Each detector is connected to a specific electrical circuit.
- the detector (31) which is in the magnetic field of the magnet (14) has electrical contact (34) closed. An electric current flows through the specific electric circuit (37).
- the detector (32) which is not in the magnetic field of the magnet (14) sees its electrical contact (35) open. No electrical current flows through the specific electrical circuit (33).
- the electrical circuit (33) is specific to the detector (32). In this way, by processing the signal, the device delivers information on the electrical state of each detector (16).
- FIG. 5 represented is a schematic view of the connections between the transmitter / receiver system and the signal processing device (17).
- Figure 5 shows that the device (17) and the transmitter / receiver system are electrically connected by the connection (27).
- FIG. 5 also shows that the receiver is composed of a master module (24) which carries the 1st end (38) of the connection (27), while the 2nd end (39) is fixed to the device (17).
- This receiver is also composed of several slave modules (25) electrically connected to each other on the one hand, and to the master module (24) on the other hand.
- the example shown in Figure 5 is not limiting, and the device can comprise a variable number of slave modules (25).
- the device (17) is connected at (40) to a power supply, and can be connected at (41) to a digital / analog converter which makes the device
- connection elements (39), (40) and (41) on the device (17) are not limiting, any other connection can be envisaged, and their arrangement on the device (17) is also not limiting, any other arrangement may be considered.
- the invention relates to any sport exercise or rehabilitation device, comprising:
- each counterweight (1) has a central opening (6) for passage of a rod (7) extending vertically
- rod (7) is movable in vertical translation and is connected to a strap or a halyard or a cable (8) for transmitting force connected to the mechanism for applying force by the user
- the device comprises a support (15) extending along a vertical axis, near the axis of movement of the weight stack (2), provided with several identical detectors (16), regularly spaced along of said support, sensitive to the magnetic field of the magnet and electrically connected to a signal processing device (17).
- the user places the key (10) between two counterweights (1) and through the selector rod (7) via an orifice (9).
- D has selected a number of counterweights (1) constituting the part of the stack (3) which it will move along the axis (5) via the transmission strap (8).
- the initial position (18) of the key (10) is therefore known to the device (16) insofar as the position of the detector (s), located in the magnetic field of the magnet (14), is known.
- detectors (16) when they are in the magnetic field of the magnet (14) are actuated and their electrical contacts fixed on an electronic module (19) are closed. The detection of the closure of these electrical contacts by measuring an electric current, enables the module to distinguish between actuated detectors (31) and non-actuated detectors (32). This identification delivers the position of the detectors on the module (19) and therefore on the support (15) and therefore of the key (10) on the axis (5). This same principle is used when the user moves the part (3) of the stack via and the transmission (8). Depending on the detectors activated, the position of the key (10) is known at time t.
- the support (15) comprises: - A rigid part (20) fixed to the frame (21) supporting the battery (2) and the mechanical guide device (22) in translation along the axis (5) , the selector (23) and the rod (7) driving in translation the part of the stack (3) by means of the key (10).
- the modules constituting the receiver system fixed on the support (15) are organized as follows:
- One of these modules is the master module (24) and the other modules are the slave modules (25) and are identical.
- Said master module (24) is electrically connected to the signal processing device (17) and to the slave modules (25) - Said master module can be connected to a variable number of slave modules, which number is determined relative to the distance maximum on which the key (10) can move.
- each module includes:
- Each module is the support for electrical circuits, the constituent elements of which are as follows:
- the detectors (16) are mounted on the circuit (26), parallel to each other, at a determined and regular pitch (28),
- step (28) is a value measured in mm which can be entered an integer number of times in the value of the height (29) of a counterweight (1).
