Definitions
- the present invention relates to a support system for a mobile device which can be oriented in various directions in space, comprising a carriage movable along a guide ramp, which serves to support said device.
- This device can be any device for transmitting or receiving radiation with directivity, such as a light source emitting a light beam, a detector offering a directional characteristic, or any device having to take various orientations during its operation. , such as a handling device ensuring the gripping of an object or a merchandise then its deposit in another place.
- the object of the present invention is to remedy these drawbacks by creating a system of the type considered which is simple and inexpensive and makes it possible to move an orientable device so that it can be easily directed in any direction, and ensure an omnidirectional scanning of space.
- the ramp has the shape of a ribbon twisted helically around a straight or possibly curved axial line, and the carriage is formed by a pair of axles with substantially parallel axes. taking the sandwich ramp, against which they are applied by means of elastic connecting means which urge them towards each other, while the orientable device is mounted in one of the two axles, so as to rotate with it around its own axis, continuously or intermittently.
- a movement of the carriage along the helical ramp is accompanied by a double rotation movement of the orientable device, namely around the axial line of the ramp, due to the helical shape of the latter , and around the axis of the axle which carries said device, due to the rotation of this axle rolling on the ramp.
- the system makes it possible to orient the aforementioned device in a simple and easy manner in an omnidirectional manner, any complicated articulated assembly henceforth becoming useless.
- this device is a source emitting a light beam, it suffices to move the carriage on its ramp to be able to illuminate any point in space.
- the two axles of the carriage have a respective weight of moment substantially equal with respect to the axis of the ramp, so that the carriage is constantly in equilibrium indifferent whatever its angular position around the 'axis of the ramp.
- the ramp offers a continuous slot along its axial line and the elastic connection means of the two axles comprise a central elastic link passing through this slot, thus ensuring the guidance of the axles along the ramp .
- each of the axles has a central body which rests on a respective face of the ramp by wheels capable of rolling there or possibly sliding there, guiding the axles when they move the along the ramp, while the swiveling device is integral with the central body of one of the two axles, this central body being coupled in rotation with the wheels of the latter permanently or intermittently.
- the carriage can be associated with a manual displacement means along the ramp, such as a cord running along the axial line thereof and which can be manually animated with a translational movement.
- the wheels of the axle, the central body of which carries the orientable device should therefore be integral with said central body, so that, when rolling on the ramp, these wheels drive the orientable device in rotation about the axis of the axle. .
- the carriage can be equipped with a remote-controlled drive motor, mounted in the central body of a first axle and comprising a casing and an output shaft, one of these two elements being prevented from rotating relative to to the axis of the second axle while the other element of the engine is coupled in rotation with the wheels of one of the axles, which constitute driving wheels for the carriage.
- the drive wheels of the carriage are those of the second axle and the coupling of the engine to these wheels is carried out via at least one lateral transmission assembly which may include either a belt passing over pulleys, or a train of 'gears, while the aforementioned orientable device is integral with the central body of the second axle.
- the orientable device is mounted in the central body of the axle, the wheels of which are the driving wheels of the carriage and each of these wheels is coupled to said central body by means of coupling means allowing free mutual rotation on a determined angle, which may be only slightly less than 360 °.
- This arrangement which has the effect of temporarily dissociating the two rotational movements to which the orientable device is subjected, makes it possible to rotate the latter over nearly 360 ° around the axis of the axle, the carriage remaining in place.
- the ramp comprises two rigid rails in the form of equal helices diametrically opposite with respect to their common axis, on which the wheels of the carriage are supported and by which they are guided.
- these two helical rails are preferably metallic and electrically insulated from each other, so as to constitute an electrical connection path, via the wheels - also metallic and insulated - of at least one of the two axles, or via friction shoes, for an electrical device at least located on board the carriage, such as the swiveling device, the drive motor, etc.
- the ramp can be provided with at least one conductive track extending along its longitudinal axis or winding helically around this axis in the same direction and at the same pitch as the ramp, the trolley being equipped with '' at least one power outlet wiper remaining in contact with said conductive track.
- This arrangement makes it possible to multiply the electrical connection paths along the ramp, intended for several electrical devices placed on board one or more trolleys.
- the system according to the present invention allows, in a simple and easy way, to orient in all directions the surrounding space all kinds of devices, directional sources or receivers of radiation, or handling devices on board a carriage traveling on a ramp as defined above, thanks to a single movement of progression of the carriage along the ramp. It is thus called for many applications, in particular:
- Figure 1 shows in perspective a part of the system according to the invention.
- 2 shows in front elevation, on an enlarged scale, the carriage of the system of FIG. 1.
- Figure 3 shows a section along line III-III of the object of Figure 2.
- Figure 4 shows, like Figure 2, a motorized version of the carriage.
- FIG. 5 represents a section along the line V-V of the object of FIG. 4.
- FIG. 6 represents a view along arrow VI of the object of FIG. 4.
- FIG. 7 represents a section along line VII-VII of the object of FIG. 4.
- Figure 8 shows, like Figure 2, another embodiment.
- a portion of a mobile lighting system comprising a carriage 1 carrying a steerable device consisting of a directional light source 2, which can move along a guide ramp 3.
- This the latter having a twisted conformation around its axis 4, is constituted by two non-linear rails 5, in the form of equal helices winding around their common axis 4 in diametrically opposite situations with respect thereto.
- These two rails are mutually secured by spacers 6 arranged from far to far.
- the carriage 1 consists of two axles 7a, 7b similar, arranged mutually opposite on either side of the two faces of the ramp 3 materialized by the rails 5, which they enclose elastically, being joined by elastic links 11
- Each axle 7a, 7b consists of a central body 8 flanked by a pair of wheels 9 admitting respectively the same axis
- Each central body 8 comprises a pair of hubs 12 which emerge laterally outside the wheels 9.
- On the hubs 12 located on the same side of the carriage 1 passes an elastic strap constituting one of the aforementioned links 11.
- an elastic strap constituting one of the aforementioned links 11.
- the wheels 9 located on the same side of the carriage 1 are covered by a pair of flanges 13, formed by disks of the same diameter as the wheels, which are mounted on the hubs 12 by central pivots 14 located on the axes 10a, Respective 10b of the axles 7a and 7b.
- the axles 7a, 7b rotate around their axes 10a, 10b while rolling on the rails 5
- the flanges 13 remain stationary, being interconnected so as not to be able to rotate around the respective axes 10a, b, without however being completely secured, which would counteract the action of the elastic bracelets 11.
- each lateral pair are connected in their contiguous regions by a bar 15 situated in their common plane and in the plane of the axes 10a, b, with respect to which each flange 13 can slide slightly (see FIG. 6).
- One of the axles namely the axle 7b, is equipped with a socket 16 intended to receive an electric bulb 17 provided with a reflector 26 (FIG. 5), the assembly constituting a light source 2 emitting a light beam in a direction D radial with respect to the axis 10b of the axle 7b.
- This bulb 17 is supplied with electric current via the rails 5 and the wheels 9 of said axle.
- the central body 8 is made of two metal parts 8 ,,, 8 physically insulated by a connecting ring 18 of insulating material.
- Each of the electrical connection pins 19 of the socket 16 is connected to a respective one of the parts 8 1 , 8 ?
- the other axle 7a which is not provided with a socket 16, has a similar structure so as not to short-circuit the rails 5.
- the movements of the carriage 1 can be obtained by direct manual action.
- An actuation can also be provided by means of a cord similar to a curtain operating cord, running along the axis 4 of the ramp 3, the carriage 1 being connected by its flanges 13 to this cord.
- the cord can be operated by hand or using an electric motor.
- the motor 19 comprises a casing 20 and an output shaft 22.
- the casing 20 is secured to the flanges 13 which flank the latter by end pieces 23 passing through the hubs 12 of the axle 7a which, for this purpose, are hollow.
- the arrangement is such that the central body 8, composed of the two symmetrical parts 8,. , 8 ? , and the wheels 9 can rotate independently around their common axis 10a, but not the end pieces 23 nor, consequently, the casing 20 of the engine, due to the connection imposed on them by the two pairs of flanges 13 relative to the axis 10b of the other axle 7b.
- the output shaft 22 of the motor 19 actuates in rotation, via a gear transmission 24 and a pair of rollers 25, the pair of parts 8. ,, 8 composing the central body 8 of the axle 7a, the movement of which rotation is transmitted via the bracelet 11 - coupled in rotation, in this motorized version of the carriage, with the hubs 12 of the two central bodies 8 - to the central body 8 of the axle 7b carrying the sleeve 16.
- the motor 19 When the motor 19 is supplied with electric current, it imparts, via the rollers 25, a rotational movement to the central body 8 of the axle 7a with respect to the end pieces 23 which, themselves, cannot rotate, due to their connection to the axis 10b of the other axle 7b by the radial arms which constitute the lateral pairs of flanges 13.
- the rotation of this central block causes the rotation of that of the other axle 7b, via the elastic bracelets 11, which rotates d first without driving the wheels 9, which makes it possible to orient the light source 2 which it carries without moving the carriage 21.
- one end 28 or 29 of the grooves 30 comes into contact with the pins 27 of the wheels 9, these are in turn driven in rotation and cause the carriage 21 to advance on the rails 5.
- the motor 19 which is mounted in the central body 8 of the axle 7a so as to respect the electrical isolation of the two parts 8, 8 ? constituting it, receives its electric power supply from the rails 5, like the bulb 17 of the light source 2 of the axle 7b.
- the starting, the direction of rotation and the stopping of the motor 19 are governed by a control device incorporated in the carriage 21, to which the corresponding orders are sent by remote control using coded signals transmitted either by the rails 5, jointly with the supply current, either by radio, infrared or ultrasound. It is also possible to provide, on an auxiliary helical support associated with the rails 5, conductive tracks for transmitting remote control commands, to which the motor control device 19 is connected via frott ⁇ urs fixed to the lateral flanges 13 of the carriage 21.
- the engine control device being designed to control, each time the latter is restarted, an inversion of its direction of rotation. It will be observed that each time, thanks to the coupling means 27, 30, the light source rotates almost one turn on the spot before the carriage 21 begins to advance. For safety reasons, only low voltage electric currents (12 V or 24 V) are conveyed by the rails 5 or the conductive tracks of the ramp 3. Furthermore, in order to facilitate assembly or disassembly operations, the ramp 3 is made up of elements with a length of around 1 meter, assembled one after the other. To these helical elements can be added flat elements, not twisted, which can, if necessary, be interposed between helical elements.
- the same ramp 3 can accommodate several manual or motorized 1 carriages 21.
- the motors are independently remote-controlled using specific coded signals, either radiated to the carriages 21, or transmitted by the rails 5 or by tracks conductive, each of which is assigned to a specific carriage 21.
- the axles of the carriage are constituted by rollers 48 composed of two metal parts 48. ,, 48 termeelectrically insulated from one another.
- These rollers one of which includes a light source 2, roll on a ramp 3 formed of two flat rails 45, of rectangular section, twisted helically around their axis 4.
- a longitudinal slot 44 which a elastic belt 51 passing over idler pulleys 42 each of which belongs to one of the axles 48, on which it is mounted coaxially in a central position.
- the guide of the carriage 41 along the ramp 3 is provided by the belt 51 cooperating with the sides of the slot 44.
- the rails 45 are fixed by supports lateral 46 inside a tube 50 made of transparent rigid material, in which the carriage 41 can circulate.
- a tube 50 made of transparent rigid material, in which the carriage 41 can circulate.
- the fact that the system contained in this tube can be electrically isolated by the latter here authorizes the use of voltages higher electrical values, for example 220 V.
