Description

The invention relates to a tachograph for recording different dates including one Driving speed, driving distance and the like Motor vehicle on a provided therein Record sheet.

It is usually a common rule that large vehicles such as trucks, buses and taxis with one Tachograph for recording vehicle data like one Driving speed or driving distance of each Vehicle should be equipped, and the tachograph is usually constructed in a cylindrical shape and with a speedometer and a rangefinder provided its front, and a circular Recording sheet can be parallel with a display plate this Measuring devices can be installed. Such are further Tachograph installed so that a cover section swiveling on a main housing to accommodate a Switch plate for opening and closing movements by means of a Joint is provided so that after opening the Cover section inserted a recording sheet and / or can be removed.

However, since the conventional one described above Tachograph a circular record sheet parallel to a display plate of a speedometer or is arranged similarly as mentioned above, the outer Diameter should not be smaller than the size of the Recording sheet itself and accordingly the vertical Expansion, in other words an outer diameter above everything that also needs to be made great. Also, since the outer diameter of the tachograph the size of the other Devices such as an engine tachometer or the like taking into account the structure of the entire construction regulated, hardly any way to rearrange a roofed structure given around the instrument panel.

Furthermore, as a driver's seat in a large vehicle like a truck or a bus in a high position  is arranged, a display panel in the instrument panel be installed so that they are out of their vertical Position is slightly inclined forward. In a little one However, the tachograph becomes a vehicle like a limousine in the instrument panel with its display panel vertical installed because the driver's seat is in a lower position arranged and designed so that convenience by maintaining the length in the longitudinal direction of the Vehicle space is increased. Therefore, since the vertical Dimension of the dashboard in a small vehicle is made larger and thereby the angle of inclination relative to Driver's seat is kept small, the driver's field of vision also tighter, which improves the ability to drive and safety Vehicle is deteriorating.

In order to avoid these problems, one was essentially box-shaped tachograph that is capable of is the roadworthiness and safety of a vehicle too increase and at the same time a leeway to arrange a new structure of the instrument panel, as in the Japanese Patent Application No. Heisei 5-50489. It is noted that one disclosed in the above application Tachograph is constructed so that a drawer, which has a recording sheet, by means of manual operation jumps out to the front.

Even when handling a tachograph that like is constructed above, however, the driver must use a forced one Position like an outstretched arm, twisting his body to the tachograph and the like for an exchange of the Take the recording sheet.

In addition, in the event that a Tachograph is installed in a control box, under Taking into account the fact that an instrument panel is one today's vehicle is more inclined and therefore the Drawer of the tachograph at a right angle this upward angle Check the tachograph for the current time adjust.

It would be further in the case that the tachograph on a  Overhead control panel is mounted, a very difficult one Task to replace a record sheet and the current one Set time.

Furthermore, if an unintended force is exerted on the outside the drawer containing a recording sheet is applied if the tray is already outside the main body, the tray is twisted, and as a result of it cannot more will be included or part of it sometimes destroyed.

The object is achieved by the invention, the above Avoiding problems and accordingly it is a task the invention to provide a tachograph, the Main body is narrow and is able to one easy operation of inserting a bundle of Record sheets and also to set the current one Allow time.

To achieve the above object, the invention has Tachograph a cassette for recording a Recording sheet and a main body for insertion and Picking up the cassette inside it, the main body continues an insertion / removal mechanism for removable picking the cassette, a clock mechanism for rotating the Recording sheet inside the cassette and also one Registration device for recording the movement data of the Has vehicle on the recording sheet.

Furthermore, the above-mentioned cassette of the tachograph according to the invention a wave on which Record sheet set with its middle section a gearwheel that is brought into engagement with the shaft and to set the current time of the sentence Recording sheets is rotated, a lid portion which openable on the upper surface for mounting the Recording sheet or to remove it from the cassette is mounted and a flap on that by the Intervention of the cassette insertion / removal mechanism of the Main body opens when the cassette is in the main body is installed and exposes a gear transmission section, to engage the clock mechanism of the main body  bring to.

In the tachograph according to the invention, the Main body has an essentially box-like shape, further it has an opening in the front section for insertion and / or removing the cassette and also a first one second and third chassis in it, which together make up the Form cassette insertion / removal mechanism, the first chassis is arranged as the top of the three chassis and is pushed forward, the third chassis as the bottom is arranged and is also pressed forward and that second chassis between these two to hold the cassette is arranged.

The main body of the tachograph according to the invention has an eject button on the front surface to remove the Cassette in contact with the first chassis and a retention mechanism as one within the main body of the components that make up the cassette Insert / remove mechanism, which is the first chassis holding back at the back end while holding the third Chassis, which is held back at the rear end, so that it moves forward when the eject button is depressed. In this case, the third chassis points further a cartridge engaging pin and one Engagement tab for engaging the retention mechanism on by the cassette when the cassette in the second Chassis inserted and accommodated in this, engaged comes with the cartridge engaging pin to the third chassis to slide back and the flap that is in the Cassette is provided by means of the engagement projection is opened, and further the engagement projection with the Retention mechanism engages to restrain the pick up the first chassis and move the first chassis forward move so that the eject button pops out.

The first chassis also has an engagement component Intervene in a head start on the respective Side surfaces of the second chassis is formed, and that Engaging component slides when the third chassis to the rear Is held back, the second chassis is moved into the side  lower position, and if the first chassis, which by means of Retention mechanism is retained in the rear side is released and the first chassis is moved forward, then the second chassis is moved up and one The recording device's recording needle is in contact brought with the recording sheet that is inside the cassette is recorded.

Therefore, the invention is constructed so that a Insert the recording sheet into the cassette using Open the flap on the cassette, align the middle one Hole of the recording sheet on the in the middle Section located shaft, closing the flap, turning the Gear for setting the current time and setting the set current time can be easily performed. The cassette then slides by sliding the cassette through the opening to the rear to get inside the second chassis to move backwards and with the Cassette-engaging pin of the third chassis on its way in Coming to the rear to engage the third chassis pushing the main body forward pushing force whereby also the closure flap of the cassette by means of Cartridge engaging pin is opened and a Gear transmission section, which with the clock mechanism of the Main body is engaged, is exposed.

On the other hand, the engagement protrusion of the third releases Chassis that engaged with the retention mechanism to be, that by means of the retention mechanism on the rear side restrained first chassis, so that the first chassis moved forward as it pushed forward becomes.

Because the first chassis is provided with an engagement component is to be engaged with a protrusion on the respective side surfaces of the second chassis the second chassis is up in line with the forward sliding movement of the first chassis and accordingly the cassette within the second chassis also pushed upwards so that a recording needle the registration device, which is inside the main body  is formed, in engagement with the recording sheet can be brought inside the cassette. It will continue Gear, which on the open flap of the cassette exposed, engaged with the watch mechanism, about rotating the recording sheet inside the cassette to start.

If the first chassis is in accordance with one Cassette insertion process moved forward stands Ejection button forward in front of the front of the Main body is formed and abuts the first chassis. This eject button must be used to remove the cassette be pushed down. If you do this, it will be the first Chassis pushed back and if it is the rear side reached, it is there by means of the retention mechanism captured. According to the backward sliding movement of the first chassis becomes the second chassis by means of the Engagement device also moves down and the Cassette inside the second chassis will go down moved so that the recording needle of the registration device lifted off the recording sheet inside the cassette becomes.

Further, when the first chassis comes in place, where it is on the rear side by means of the retention mechanism is retained, the engagement projection of the third Chassis that engages the restraint mechanism disengaged and the third chassis moves in the main body forward due to a compressive force. In this Case jumps because the cartridge engaging pin of the third Chassis pushes the cartridge away from the back, part the cassette through the opening. After that, the cassette be taken out of the main body by hand to do this Record sheet exchange the current time adjust and the like

Fig. 1 is a perspective view showing an embodiment of the tachograph according to the invention, in which reference numeral 1 denotes the box-shaped main body of the tachograph and reference numeral 40 denotes a cassette for receiving a recording sheet. As shown in the figure, the main body 1 has a front panel 2 which has a shutter for opening and / or closing a lid 3 , an operation switch 5 for use when changing drivers, and an eject button 6 for removing the cassette 40 when the Lid 3 is open, and in which there is also an opening 7 for inserting and / or removing the cassette 40 . It is noted that the main body 1 is as large as a car radio or the like, which is 180 mm wide and 170 mm deep.

The cartridge 40 further has a narrow box-like housing 41 and a shaft 42 formed in the central portion thereof, as shown in Figs. 2A, 2B, 2C and 2D, which are a plan view, a side view, a front view and a bottom view of FIG Are cassette. On the upper surface of the housing 41 , a flap 43 is provided which can be pivoted about a hinge 41 A, which is formed on the side surfaces of the housing 41 , and essentially at an angle of 90 degrees relative to the cabinet surface, as in Fig . 2B, can be opened. The flap 43 has a handle 43 a, so that it can be opened by pulling the handle 43 a.

With open valve 43, the recording sheet 50 may be on the disposed in the central portion of the housing shaft 42 fixed contact and a part of the recording sheet 50 is located through a top surface of the housing 41 in the opening 41 formed b-free.

Further, on the left front side of the case 41, a gear 44 projects and engages with the shaft 42 through a gear train disposed inside the case 41 , so that the shaft 42 rotates in accordance with a rotation of the gear 44 and the time of day of the recording sheet 50 can be set.

A groove 41 c is formed on both edge sides of the lower surface of the housing 41 and a switch 45 is accommodated in one of the grooves 41 c, whereby a closure flap 46 , which is shown in FIG. 2D, is opened when the switch 45 in the direction indicated by an arrow is pushed and subsequently the gear arranged therein is exposed. The sliding operation of the switch 45 is normally carried out when the cassette 40 is inserted into the main body 1 of the tachograph, whereby the shutter 46 is opened and the gear therein engages with a clock mechanism of the main body 1 .

The internal structure of the main body 1 of the tachograph will now be explained as follows.

Fig. 3 shows a side view of the main body 1 , in which both a case covering the upper and lower surfaces of the main body 1 and a registration device for recording the vehicle data on a recording sheet are omitted here and the cassette 40 is also not mounted .

As can be seen from the figure, a ceiling shell 90 is provided within the main body 1 , which is retained and fastened by means of the front plate 2 and a base plate 8 . Under the ceiling shell 90 , a first chassis, a second chassis, and a third chassis are arranged in this order.

The first chassis 60 , as shown in FIG. 4, has an iron plate that has a U-shaped opening at its central portion, and further has a recess 61 on the outside of the front together with a keyhole-shaped opening 62 on the outside Back on. The first chassis 60 is slidably attached to the ceiling shell (not shown) by means of bolts 63 which are correspondingly fitted in the recesses and openings.

An end portion of a spring 64 in the center of the respective outer sides is attached to the first chassis 60 is further secured respectively to the chassis and the other end of each of these springs (not shown) on the ceiling shell 90 attached, so that the first chassis 60 to the front, in in other words, the front panel 2 is pressed. The first chassis is also provided on the side surface with a transversely protruding pin 65 , which pin 65 , as shown in FIG. 3, is retained by an arm 101 of the retention mechanism 100 attached to the ceiling shell 90 .

The retention mechanism 100 has a fixed part 102 and a substantially V-shaped arm 101 which is pivotally attached to a pin 103 of the fixed part 102 , whereby the fixed part 102 is fixed to the ceiling shell 90 and the arm 101 is forced, to pivot pin 103 in the direction indicated by an arrow.

An opening 104 is formed in a portion of the arm 101 .

Since the pin 65 is retained by the arm 101 of the retention mechanism 100 , the first chassis 60 is retained on the rear side even though it is pushed forward. This retention state is generated by pressing the eject button 6 to remove the cassette which has already been installed. In more detail, before the eject button 6 is pressed, the cartridge 6 was assembled and the pin 65 of the first chassis 60 was pressed against the end portion of the arm 101 of the retention mechanism 100 as shown in FIG. 6, and in this state, when the eject button 6 is pressed, the first chassis 60 is also pushed back so that the pin 65 is finally retained by the arm 101 .

The second chassis and its operation are as follows explained.

The second chassis 70 is made of iron and has a substantially cup-shaped shape, in which projections 71 a, 71 b and 71 c (not shown) are arranged horizontally and on the side faces of the chassis, as shown in FIG. 3, respectively , project. The middle protrusion 71 b is set between the flanges of a fork-shaped regulating member 95 which is fixedly attached to the ceiling shell 90 , thereby preventing sliding movements of the second chassis 70 forwards and backwards.

Furthermore, the first chassis 60 also has a pair of right-angled side plates 66 (each equivalent to an engagement member according to the invention) on their respective side surfaces, and each of these side plates is provided with a substantially diagonally cut groove 67 , with which the projection 71 a of the second Chassis 70 fits together.

Due to the above structure, even if the eject button 6 is pushed backward because the pushing of the second chassis 70 forward and backward by the regulating member 95 is prevented, the projection 71a by means of the groove 67 of the side plate 66 of the first chassis 60 is guided downward, and when the first chassis 60 comes to the position in which it is held on the rear side by the restraining mechanism 100 , the second chassis 70 comes to a stop.

FIG. 4 is a top view omitting the ceiling pan 90 and the two projections 72 shown in the figure, which are provided at the rear end of the second chassis 70 , are stops for holding the cassette when it is installed. Further, reference numeral 110 in the figure denotes a clock mechanism, the projecting gear 111 of which engages with the gear provided behind the shutter 46 of the cassette 40 to rotate the recording sheet.

The third chassis 80 and its operation are explained below.

The third chassis 80 is also made of iron and is placed under the second chassis 40 as close as possible to it, as shown in FIG. 5, a protruding piece 73 formed on the second chassis 70 with an opening 81 of the third chassis 80 in Is engaged so that the horizontal and vertical movement of the third chassis 80 is restricted. One end of the spring 82 is attached to the central portion of the third chassis 80 , while the other end thereof is attached to the second chassis 70 .

The third chassis 80 is pressed forward, in other words towards the front cover 2 , by this spring 82 .

Further, the third chassis 80 has a pair of pins 83 engaging the cassette centrally on the side surfaces, and both pins 83 face vertically upward. In addition, a protruding portion 84 is formed on one of the side surfaces of the third chassis 80 , and an upward engaging protrusion 85 is provided at the upper end thereof for engaging the restraint mechanism. It is noted that in FIG. 5, the second chassis 70 is indicated by a chain line, although it could be seen in the current construction.

When the cassette 40 is inserted through the cassette insertion / removal opening 7 of the front cover 2 (see Fig. 1), an end face of a groove 41 c (see Fig. 2) formed on the back of the cassette 40 with the engaging pin 83 in the cassette, and when the cassette is advanced, the third chassis 80 is advanced, causing it to be pushed back against the urging force of the spring 82 . In this situation, to engage the restraint mechanism, the engagement protrusion 85 of the third chassis 80 enters the opening 104 formed in the arm 101 of the restraint mechanism 100 that restrains the first chassis on the rear side and pivots the arm 101 against the pressing force, whereby the pin 65 of the first chassis 60 disengages from the arm 101 and, as shown in FIG. 6, the first chassis 60 moves forward and the pin 65 is moved into a position, to hit the upper end of arm 101 .

Since the projection 71a formed on the side surface of the second chassis 70 matches the groove 67 formed on the side plate 66 of the first chassis 60 , this projection is guided in the groove 67 as the first chassis 60 moves forward, and as a result thereof second chassis moved up. Since the protrusion 71 b protruding from the center of the side surface of the second chassis 70 is prevented from both forward and backward free movement by the regulating member 45 formed on the ceiling pan 90 , the second chassis 70 cannot move in the directions given above.

When the second chassis 70 is raised up, the cassette 40 inserted in the main body is also raised so that the recording sheet 50 accommodated in the cassette 40 is brought into a position in which it is in contact with the recording needles of the registration device (below explained) can come. The cassette 40 is directed upward and the recording sheet 50 is from the opening 51 b of the housing 41 of the cassette 40 exposed, so that the recording needle of the recording device in contact with the recording sheet through the opening (not shown) of the top shell 90 and a U- shaped opening of the first chassis 60 can be brought. FIG. 7 shows a top view of the state in which the cassette 40 is already installed, whereas FIG. 6 shows a side view of this state. Fig. 8 is a bottom view in which the ceiling pan 90 , the bottom plate 8 and the cassette 40 are omitted.

The registration mechanism and its mode of operation will be now explained as follows.

Fig. 9 shows an example of a registration mechanism, but in an upside-down state. In Fig. 9, reference numeral 11 denotes a motor, and the shaft 11 a is provided with a gear 12 , 13 denotes a countershaft, 14 denotes a bevel gear which is in engagement with a last gear of the countershaft 13 and 15 A and 15 B. Drive wheels, which are in engagement with the bevel gear 14 , 15 A rotates a recording needle drive cam 16 A, while the other drive wheel 15 B rotates a recording needle drive cam 16 B. 17 A, 17 B are L-shaped pivotable lever pivoting about a fulcrum O by the recording needle driving cam 16 A, while 17 C a L-shaped pivotable lever for pivoting about a fulcrum O by the recording needle driving cam 16 is B, and 18 A and 18 C are recording needles which are pressed down (upward in Fig. 9) by means of the pivoting levers 17 A, 17 B and 17 C, respectively. These recording needles 18 A, 18 B and 18 C are all in engagement with a locking piece 19 A, 19 B and 19 C, between these locking pieces 19 A, 19 B and 19 C and frame-like bodies 20 A, 20 B and 20 C coil springs 30 A, 30 B and 30 C are each arranged to support the recording needles 18 A, 18 B and 18 C, so that the recording needles 18 A, 18 B and 18 C are downward (upward in Fig. 9) are pressed.

Furthermore, projections 17 Aa, 17 Bb 17 Cc of the pivotable levers 17 A, 17 B and 17 C abut against the upper side surfaces of the locking pieces 19 A, 19 B and 19 C, with end portions of the respective pivotable levers 17 A, 17 B and 17 C push against the recording needle drive cams 16 A and 16 B by means of the compressive force of coil springs 30 A, 30 B and 30 C.

The recording needle 18 A is used to record the route, whereas the recording needle 18 B is used to record a driver change and 18 C is used to record the vehicle speed. Further, a recording needle drive mechanism is used to push the recording needles 18 A, 18 B and 18 C in the radial direction of the recording sheet as in conventional drive mechanisms, so that no explanation will be given here. The registration mechanism and its operation will now be explained as follows.

In the state in which the recording needles 18 A, 18 B and 18 C are raised, when it is discovered that the cartridge 40 is installed, the motor 11 is controlled by a signal from a lock detection mechanism (not shown) to release the recording needle. Swivel drive cams 16 A and 16 B by 180 °. By this movement, the pivotable levers 17 A, 17 B and 17 C are all pivoted and accordingly their respective projections 17 Aa, 17 Bb and 17 Cc are moved downward, so that the recording needles 18 A, 18 B and 18 C also by means of the pressing force of the springs 30 A, 30 B and 30 C are moved down (raised up in Fig. 9) and come into contact with the recording sheet 50 . As a result, different vehicle data can be recorded on a recording sheet by means of the recording needles 18 A, 18 B and 18 C.

Further, when the cartridge 40 is installed and the recording needles 18 A, 18 B and 18 C all abut against the recording sheet 50 , when a key is inserted into the lock 4 of the main body 1 and rotated clockwise, the Motor 11 controlled based on the output signal of the lock detection mechanism, which passes that the cartridge 40 is unlocked.

As a result, since the recording needle drive cams 16 A and 16 B are rotated another 180 ° to return to the initial state, the recording needles 18 A, 18 B and 18 C, which are caused by the compressive force of the coil springs 19 A, 19 B and 19 C have been moved downwards by means of the pivotable levers 17 A, 17 B and 17 C against the pressure force of the respective coil spring 19 A, 19 B and 19 C and finally removed from the recording surface of the recording sheet 50 .

Thereafter, when the eject button 6 is released, the first chassis 60 is pushed in as shown in FIG. 3, and the pin 65 formed on the side surface thereof is retained by the retention mechanism 100 and by rotation of the Arm 101 of the retention mechanism 101 disengages the engagement protrusion 85 of the third chassis 80 and the third chassis moves forward to eject the cartridge 40 through the cartridge insertion / removal opening 7 of the front panel 2 . Thereafter, the cassette 40 can be pulled out, a new desired recording sheet 50 inserted, the clock set, and the like.

As already explained, since a tachograph according to the invention receives a cassette for inserting the data sheet 50 and an exchange of the recording sheet or an adjustment process of the watch can be carried out by an operator by hand, a simple replacement of the recording sheet 50 is made possible.

In a tachograph according to the invention, a Recording sheet is recorded in a cassette and the Cassette is installed in the main body, an exchange of the Recording sheet can be done by hand and a Adjustment process can also be carried out easily, whereby overall ease of use is increased.

Further, there may be recording sheets in the cassette be included an installation of the main body of the Tachograph in the vehicle without taking into account the Available space.
