Definitions
- the invention relates to the field of devices forming panels of measuring instruments such as speedometers, revolutions, gauges of any kind and of fuel or temperature in particular, in motor vehicles of any kind, but also, for other instruments such as manometers or others in particular installations.
- these instruments comprise an indicator member held by its hub on the shaft or output axis of a rotation drive means and whose pointer end or a pointer travels the track of a graduation of circumferential shape or approximately or partially circumferential which could also on one or more of its portions have the shape of a circular arc string and appear on the periphery of a support often called front plate or dial may include on the back a printed circuit.
- This front plate is traversed by the aforementioned output shaft of the drive means itself under, or behind, it.
- the instrument is at least analog.
- Said indicator member may be of various shape (needle but also disk with pointer for example). It can be illuminating or illuminated, or partially hidden, the current technique by offering a wide range.
- the driver will adjust the combined steering wheel and seat settings according to their morphology, size and needs in terms of driving position. In very In many cases, however, said combined settings interfere with the driver's field of view.
- the range in the upper portion of the graduation thus masked can extend from the value 70 km / h to the value 170 km / h or from 45 to 105 MPH according to the models speed counters.
- the critical speed indications 90-110-130 km / h or their equivalents in MPH pointed by the needle, are no longer visible to the driver. (On the gauges, it is in the red areas indicating overheating of the engine or the minimum fuel level that the indicator end of the needle would not be visible).
- the driver will, while driving, change its position in the seat, bend his head, or even contort and look from below or from above the upper portion the circle of the steering wheel in order to be able to observe the indication given by the counter hand (or even the rev counter for the engine speed, or even gauges) when it is in the range of the graduation masked by said portion circle.
- This behavior can be dangerous.
- the device according to the invention makes it possible to remedy at least partially this major drawback.
- the invention consists of an instrument panel device for measuring a physical quantity over a measurement range and comprising:
- a dial comprising a main scale indicating values of said physical quantity.
- An indicator member fixed on an output axis of a rotating drive means, and movable with respect to the dial so that a first pointer of said member indicates on the main scale the value of said physical quantity which must to be indicated,
- said second pointer indicates said value on the second scale when the first pointer indicates the same value on the main scale, said device being designed so that for an observer looking at the dial in the direction allowing it to read the indications to the place, if the first pointer is in the upper part of the dial, the second pointer is substantially in the lower part of the dial, thus making it visible to said second pointer for a user when the first pointer is not, for example because of a visual obstacle such as part of a steering wheel of a motor vehicle.
- the indication is masked by an element external to the device (the steering wheel in a motor vehicle for example) the user can see without fault, the indication of the same value given simultaneously on the second graduation in the lower part of the dial.
- the indicator member may consist of a rectilinear needle in two parts of unequal length on either side of a hub and whose end of the longest part constitutes the first pointer, and the end of the the shortest part is the second pointer,
- the main graduation may extend, printed in the shape of an approximately circumferential track, around the dial, and the second graduation may extend, printed in characters of appropriate size, in the form of an arcuate circle track, on the dial below of the output axis of the driving means, in the part bottom of the circle formed approximately by the indication characters of the main graduation,
- these graduations in a linear reading from left to right, can be inverted with respect to each other, the indications of the second graduation being identical to those of the principal graduation, approximately between 270 ° and 90 ° of the circle formed by said principal scale on the dial in the direction of clockwise, the origin 0 ° (and the value 360 °) being located at the high end of said circle, and are spatially opposed to them relative to the output axis of the drive means,
- the indicator member may consist of a disk or a similar form of disk, comprising a first projecting pointer opposite the main scale and, on the opposite side, a second pointer or a window facing it; of the second graduation,
- the indicator member may consist of a disc or a similar disc shape, comprising a first pointer opposite the main graduation and, opposite, printed in an arc of a circle on the edge of the indicator member; non-inverted second graduation,
- the second graduation passes in front of said second pointer applied to the dial, in the lower part of the circle formed approximately by the main graduation, the positioning of said second pointer determining the positioning of the second graduation on the edge of the dial; the indicator organ.
- the present invention also relates to a doubled reading indicator device for control instruments, comprising:
- An indicator member comprising at least one pole, fixed by its hub on the output axis of a rotating drive means which moves it above said dial, said pole being opposite the graduated scale or indications main track which extends in the form of an approximately circumferential track around said dial.
- Said device further comprises a graduated scale or second indication, and a second pole opposite said graduated scale or second indications in a suitable size, a specific part of the main scale, designed so that said second pole is located substantially in the lower part of the dial if the first pole is located in the upper part of the dial for an observer looking at the dial in the direction allowing him to read the indications at the place, so as to allow the latter, when the indication given in said specific part, on the scale or principal indications, is masked by an element external to the device, the steering wheel in a motor vehicle for example, to see without fault, the indication of the same value given simultaneously on the graduated scale or second indications.
- FIG. 1 represents a plan view of the device according to a preferred form of the invention
- Figure 2 shows a sectional view of the device of FIG. 1,
- Figures 3, 4 and 5 show a plan view of three variants of the device.
- the measuring instrument panel device in a preferred form of the invention, comprises a circular dial 1 provided with a main scale 2 and a second scale 3 which incorporates some of the values of the main graduation 2.
- the device also comprises a rectilinear needle 4, in two parts of unequal length on either side of its hub 5 by which it is fixed to the axis 8 of a rotating drive means 9.
- the first pointer 6 belongs to the part of the needle 4 which is the longest since its hub 5.
- a second pointer 7 consists of the end of the shortest part of the needle 4.
- the hub 5 is about 3/5 of the length of the body of the needle 4.
- the needle 4 travels, in a plane parallel to the dial 1 and above it, by its first pointer 6, the main graduation 2 which extends in the form of an approximately circumferential track around the dial 1, and by its second pointer 7, the second graduation 3 which extends in the form of an arcuate track within the axis 8, on a location always visible to the user in the lower semicircle formed approximately by the main graduation 2 on the dial 1.
- the indications on the second graduation 3 correspond to indications of the main graduation 2 which are spatially opposed to them with respect to the axis 8. Thus their values are identical but in a linear reading from left to right, their scales are inverted relative to each other.
- the indications concerned are established respectively, in a reading from left to right, for the main graduation 2, in its upper portion, of the value 7 0 to the value 170 and for the second graduation 3, from the value 170 to the value 70. That is to say that at all times, while the indication given by the first pointer 6 of the needle 4 on the main graduation 2 is hidden under the conditions described above, the user, without the need to change its position in its seat or contort, will see without fault, the indication of the same value given by the second pointer 7 of the needle 4 on the second graduation 3.
- the indicator member 4 is in the form of a disc (or approaching) with a first pointer 6 at a point of its periphery, opposite the main graduation 2. It has the opposite of said first pointer 6, a second pointer 7, or a window according to a non-illustrated variant, facing a second (inverted) graduation 3 on the dial 1, similar to the second graduation 3 described above.
- the indicator member 4 is disk-shaped (or approaching) with a point of its periphery, a first pointer 6 facing the main scale 2. It has the opposite of said first pointer 6, applied in an arc of circle on the disc 4, a second graduation 3, not reversed, which scrolls, during the rotation of the indicator member 4, in front of a second pointer 7, placed this time on the dial 1 and whose positioning on the dial 1 determines the positioning of the second graduation 3 on the indicator member 4.
- the indicator member 4 is a needle concealed by a fixed plate 12 having a window 13 revealing the second pointer 7, and a second graduation 3 in an arc of circle applied to the fixed plate 12.
- the general structure of the device and its components including the axis 8 and the drive means 9 are known without the need to detail them.
- the materials used are common and may be subject to change especially in the context of sustainable development.
- Current luminescence techniques for indicating devices can be used for the device according to the present invention.
- the second graduation 3, in its structure as shown in Figure 1, could be of linear form. It will be readily understood that if said second graduation 3 is located in the upper part of the dial 1, for example very close to the axis 8 of the drive means 9, and in this case its scale would not be reversed, nevertheless its reading would be imperfect, the needle 4 hiding the relevant indication except to make a window. This is why the invention is intentionally limited to embodiments in which if the first pointer 6 is in the upper part of the dial 1, the second pointer 7 is substantially in the lower part of the dial 1.
- the second graduation 3 will normally be entirely in the lower part of the dial 1. Nevertheless, it is possible, as indicated above, to complete the second graduation 3 over almost the entire turn of the dial 1, taking over the entire main graduation 2. This is not very useful, but in this case part of the second graduation 3 will be in the upper part of the dial 1. It remains the case that when the first pointer 6 is in the upper part of the dial 1, the second pointer 7 will actually be in the lower part of the dial 1.
- the second pointer 7 is not opposite to the first pointer 6 relative to the hub 5, and therefore not offset by 180 °, but for example 150 °.
- the first pointer 6 is already in the upper part of the dial 1
- the second pointer 7 is not yet in the lower part, the second graduation 3 projecting slightly over the upper part. of the dial 1.
- Such an offset may be desired because of the particular shape of a steering wheel or dashboard. It remains true that when the first pointer 6 is in the upper part of the dial 1, the second pointer 7 is substantially in the lower part of the dial 1. Either there is indeed, or it is very close and will be there soon that the first pointer 6 will go a little further in the upper part of the dial 1.
- the important thing in the context of the present invention is to make the driver benefit from an area visible on the dial 1 by means of the second graduation 3 and the second pointer 7 for the speed measurements indicated in the upper part by the main scale 2 in its part that would be hidden from the view of the driver by an element outside the device, a part of the steering wheel for example.
- the first pointer 6 can not cooperate with the graduation second 3, and conversely that the second pointer 7 can not cooperate with the main scale 2, so as not to create confusion.
- This goal can be achieved in different ways, whether through the use of different colors, or by designing a dial where the graduations are in different planes, while each of the pointers is shaped to cooperate only with the graduation to which he is dedicated.
- the device according to the invention is particularly intended for measuring or control instruments, speed meters, revolutions counters, gauges of any kind and of fuel or temperature in particular, manometers and others to ensure a flawless visibility of their indications so to improve remarkably and in a general way, their reading comfort and in a particular way, in motor vehicles of any kind, driving comfort and safety.
