Description
~2~5325`
The present invention rela~es to a device for sucking out exhaus~s from vehicles having upwardly directed exhaust pipes.
It is noted that prior art devices for sucking out exhausts from vehicles are useless or at least unsuitable for vehicles having upwardly directed exhaust pipes.
The object of the present invention is therefore to provide by simple means, an efficient and in certain aspects automatically operating device for sucking out exhausts from vehicles having upwardly directed exhaust pipes. This is made possible while the present device has the characterizing features defined in the following clai~ 1.
The invention will be further described below with reference to the accompanying drawings, wherein fig.
1 is a side view of a device according to the invention, mostly in section; fig. 2 is a section along the line II-II in fig. l; fig 3 is a side view of an alternative embodiment of the device according to the invention; fig.
4 is a plan view of a second alternative embodiment of a device according to the invention; and figs. 5A - 5C
schematically illustrate various situations when using the device according to the invention.
In fig. 1, a flue 1 is illustrated having the shape of a so called exhaust track which down below is provided with sealing lips 2 that engage each other for sealing the track. The sealing lips 2 may temporarily be brought apart by means of an exhaust receiving carriage 3 for passing exhausts into the track 1 via said carriage 3. The carriage 3 is suspended on the track 1 (not shown) and the track is mounted in the ceiling via wheel alighting gears 5, permitting the track 1 to move perpendicular to its longitudinal axis.
12~S3ZS
The exhaust receiving carriage 3 is down below provided with a terminal tube 6 to which a nozzle 8 is connected via a connecting device 9. The nozzle 8 has an exhaust pipe connection 10 for cooperation with an upwardly directed exhaust pipe 11 on a vehicle (not shown).
In the embodiment of fig. 1, the exhaust pipe connection 10 comprises on one hand a wall portion 12 of the nozzle 8 and on the other hand two spring-loaded coupling arms 13, 14. Each coupling arm 13, 14 is pivotally mounted on the nozzle 8 via axes 15, 16 and outside these axes, the coupling arms 13, 14 are affected by spring means 17, 18 which constantly try to swing inner portions 19, 20 of said arms 13, 14 towards the wall portion 12.
By means of said spring means 17, 18, the coupling arms 13, 14 may swing aside when a vehicle moves along the track 1 and the exhaust pipe 11 thereof reaches said coupling arms 13, 14. The ~xhaust pipe 11 will move relative to the nozzle 8 until it strikes the wall portion 12, whereafter said nozzle 8 is forced to follow the exhaust pipe 11 until the vehicle stops. From that moment the exhaust pipe 11 reaches the nozzle 8, the exhausts therefrom are sucked into the nozzle 8 and via said nozzle and the carriage 3 passed to the track 1 and therefrom to a suitable area or purifying plant.
When the vehicle moves in the opposite direction (e.g. when driving out from a garage 21; see figs. 5A-5C), the exhaust pipe 11 will strike the coupling arms 13, 14. Because of the force of the springs 17, 18, these can not swing aside and the nozzle 8 is forced to follow the exhaust pipe 11. Hereby, the exhaust pipe 11 will move towards one end of the track 1 (e.g. at the garage door 22) and a buffer 23 arranged at said end~ The nozzle ~21~;32S
~ 3 --8 will be stopped immediately ~y said ~uff~r 23, whereby the load of the exhaust pipe 11 on ~he coupling arms 13, 14 is momentarily increased t~ a high extent such that the springs 17, 18 yield and the coupling arms 13, 14 may swing aside and release the exhaust pipe 11. Hereby exhausts have been sucked away via the nozzle until the vehicle has reached a certain area (e.g. the garage door) and at the same time, the nozzle 8 has been displaced to a receiving position (see fig. 5A) for recei~ing the exhaust pipe 11 of a vehicle to be moved along the t~ack 1 (e~g. into the garage 21).
When a vehicle is driven into the garage 21 via the garage door 22 (arrow A, flg. 5A), the exhaust pipe 11 thereof will move into the~nozzle 8 or strike one of two guide rails 24 extending forward/outwards from said nozzle 8 and preferably resilient. If the vehicle continues in direction A into the garage 21, the exhaust pipe 11 will, through its load on one guide rail 24, draw the track 1 in the direction of arrow B (see fig. 5B) until the exhaust pipe 11 has reached the wall portion 12 of the nozzle 8. Thereafter, the exhaust pipe 11 will move the nozzle 8 along the tra'ck 1 until the vehicle has reached the desired position (see fig. 5C) in the garage 21 or corresponding place.
While the exhaust track 1 is movable sideways (via the wheel alighting gears 5), the exhaust pipe 11 of the vehicle may itself "draw the nozzle correct" also if the vehicle is not driven into the garage 21 with the exhaust pipe 11 positioned straight before the nozzle 1~S3~5 Instead of or in com~ination with arranging the track 1 movable in sideways direction, the nozzle 8 may be pivotable in sideways direction. To enable this, the exhaust receiving carriage 3 has an axis 25 (see fig.
3) arranged parallel with the track 1 and on which the nozzle 8 is pivotally mounted via a collar 26 extending into the connecting tube 6. In order to provide sufficient sealing, a flexible hose 27 is threaded onto the connecting tube 6 and a corresponding portion of the nozzle 8.
Instead of or as an alternative to the above-mentioned embodiments, the nozzle 8 may be pivotally arranged on the exhaust receiving carriage 3 such that it may pivot around a vertical axis (not shown) when it is loaded by the exhaust pipe 11.
At the nozzle 8 of fig. 4, the exhaust pipe connection comprises two pairs of coupling arms 13, 14 instead of one pair of coupling arms 13, 14 and the wall portion 12 which thus has been deleted. The other pair of coupling arms 13, 14 is reversely arranged and the nozzle has two substantially identical but reverse inlets/outlets for the exhaust pipe 11.
This nozzle embodiment permits movement of the exhaust pipe 11 into and out from the exhaust pipe connection 10 from two opposite sides, which means that a vehicle can drive into a local through a gate, bring the nozzle along therewith through the local and pass out through another gate, where the nozzle strikes a buffer (not shown).
~Z153ZS
Thereafter, a vehicle may drive through the second gate and bring along the nozzle to the first gate or the nozzle may be automatically displaced between the gates by means of a special driving device (not shown).
As ana--Lt~na-~iveor complement to the plant described above, a releasing device (not shown) may be arranged within the area of movement of the nozzle 8 for cooperation with the exhaust pipe connection 10 such that said connection is released for disengaging the nozzle 8 when reaching the releasing device. The releasing device is preferably adjustable for releasing the exhaust pipe connection or not, and if said connection has coupling arms 13, 14, it may ~e designed to affect these arms.
The invention is not limited to the above embodiments, butmay vary within the scope of the following claims.
Thus all details shown may have different shapes. The nozzle 8 may e.g. have another design without loosing its suckingf~n~on and the exhaust pipe connection 10 may have another shape than in the drawings. This applies also on the guide rails 24 and the connecting device 9 (which is only schematically shown in fig. 1).
The nozzle 8 is through the exhaust track 1 connected to an exhaust suction device, e.g. a fan, which is not shown while such arrangements are already known and the device according to the invention may be used wherever exhaust suction from upwardly directed exhaust pipes is required, e.g. in garages, work shops, storages, fire stations, etc.
The present invention rela~es to a device for sucking out exhaus~s from vehicles having upwardly directed exhaust pipes.
It is noted that prior art devices for sucking out exhausts from vehicles are useless or at least unsuitable for vehicles having upwardly directed exhaust pipes.
