Description

(54) VENTILATOR ASSEMBLIES FOR PUBLIC SERVICE AND OTHER VEHICLES (71) We, WILFRID OVERTON LIMITED, a British Company of Intown, Walsall, West Midlands, WS1 1SJ, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to openable ventilator assemblies primarily, though by no means exclusively, roof ventilator assemblies for vehicles, for example for public service vehicles, such as motor coaches. It is concerned with ventilator assemblies of the kind in which a ventilator panel, usually of approximately rectangular shape, can be lifted or opened at will at either of two opposite edges, or at both edges simultaneously.
Numerous proposals have been made on these lines, employing various pivoted linkages such as toggle linkages, or straight or curved links or scissors linkages connecting the edge of the panel to points on the frame that surrounds the opening in the roof or other surface.
It is desirable that the panel should remain firmly held after it has been set in an open or partly open position, despite buffetting from wind loads and shaking when the vehicle passes over rough road surfaces, yet at the same time the panel should be easy to move and set in the required position without requiring any difficult or complicated movements and without requiring the tightening of screw clamps or other such devices. The aim of the invention is to achieve this result.
According to the present invention we provide a ventilator assembly comprising a frame having an opening and a ventilator panel adapted to close the opening, the panel having at each of two opposite edges thereof a pair of oppositely inclined links arranged to control movement of the respective edge of the panel towards and away from the opening, respective outer ends of the links being pivotally connected to the frame and respective inner ends of the links being connected to respective plungers, both plungers being movable towards and away from one another axially within a hollow tubular handle mounted on the panel, releasable locking detent means acting between the handle and the plungers to lock both plungers against axial movement with respect to the handle in each of at least two possible axial positions, the locking detent means being actuated by manually operable means mounted on or formed by the handle.
Preferably the locking means comprises a detent arranged within the handle and engageable with notches formed in both plungers, and a release member is arranged on the outside of the handle and is manually operable to release the detent.
The detent is preferably biassed by a spring to the locking position. The detent may engage a selected pair, of several notches formed on the plungers so that the associated edge of the panel can be locked in the closed position, the fully open position, and one or more intermediate positions. For example there may be five notches giving three intermediate positions as well as the open and closed positions. The release member preferably comprises a button fixed to the outer end of a stem which extends transversely of the handle through an opening in the wall of the handle, the detent being fixed to the inner end of the stem and a helical coil spring being carried on the stem between the button and the wall of the handle.
The invention will now be described in more detail with reference to the accompanying drawings in which: Figure I is a side view showing a ventilator assembly according to the invention comprising a ventilator panel mounted on a frame, with the panel in the closed position; Figure 2 is a view similar to Figure 1 showing the panel in the fully open position; Figure 3 is a view similar to Figures 1 and 2 showing the panel in an intermediate open position; Figure 4 is a side view of a handle and associated control means forming part of the ventilator assembly shown in Figs. 1 to 3; Figure 5 is a section on the line 5-5 of Figure 6; and Figure 6 is a plan view of the handle shown in Figure 4 with the upper wall removed to show more clearly the parts of the control means inside.
Referring to the drawings, Figures 1 to 3 show a ventilator panel 1 mounted on a frame 2 defining an opening 3, for example in the roof of a vehicle (not shown) such as a motor coach in which a roof panel of the assembly is shown in three different positions of use, that is fully closed, fully open and partly open. The panel comprises a transparent sheet 4 mounted by means of a bead 5 made of resilient material in a surrounding frame with a downwardly depending flange 6 which carries a flexible sealing element 7.
The sealing element 7 is designed to engage and seal against the roof area surrounding the frame 2 when the assembly is in the closed position shown in Figure 1. All this is well known and need not be further described.
The present invention is concerned with the control means for controlling movement of the panel between the various positions of use. In this embodiment the panel 4 is substantially rectangular in shape and each of two opposite edges of the panel is controlled by a respective handle 9 and associated control means 10. However it will be understood that the panel could be of any shape e.g.
circular in which case the two handles and their associated control means would be mounted at opposite ends of a diameter of the panel. The ends of the diameter would then correspond to two opposite edges of the panel.
In this specification the term 'two opposite edges' is not intended therefore to be restricted to the case where the edges are straight and parallel.
One handle 9 and associated control means 10 is illustrated in more detail in Figures 4 to 6. The other handle and associated control means are of identical construction and consequently the following description will be limited to one handle and associated control means.
The handle 9 is made from a length of square section tube 11 to which two brackets 12, 13 are rivetted. The brackets provide means for securing the handle 9 to the panel 4. The control means includes a pair of links 14, 141 and a pair of plungers 15, 151. Each of the plungers 15, 151 basically comprises a bar 16 cut from rectangular bar having a depth corresponding to the internal depth of the tube 11 so as to be a sliding fit in the tube.
The width of the bars 10 is very much less than their depth and they are arranged in the tube 11 on opposite sides of a longitudinal axial plane of the tube with a space between them. As shown most clearly from Figure 6 two relatively short bars 18, 19 are rivetted to the outer end of each of the bars 16 to form a U-shaped opening 20 at the outer end of each plunger. Conveniently the bars 18, 19 are cut from the same stock of rectangular bar as the bars 16. The maximum width of each plunger is less than the internal width of the tube 11 and spacers 21 are secured to the outer ends of the tube 11 on opposite sides of each plunger. In addition spacers 22 are secured to either side of the bars 16 at their inner ends. The spacers 21, 22 ensure that the plungers are retained in their correct lateral positions during sliding movement relative to each other and the tube 11. Furthermore each of the plungers is provided with a stop 23 secured to the side of the bar 16 adjacent to the inside wall of the tube 11.
The stops 23 are arranged to engage the spacers 21 at the ends of the tube 11 to prevent the plungers being completely withdrawn from the tube 11. The outer end of each plunger projects from an associated end of the tube 11 and one end of each link 14, 141 is pivotally mounted in the openings 20 at the ends of the plungers 15, 151 respectively. The other end of each link 14, 141 is adapted to be pivotally mounted on the frame 2 of the vehicle. As shown most clearly in Figure 5 the inner end portion of each bar 16 is of reduced depth and provided with teeth 24 formed by cutting notches 25 into the edge of the portion of reduced depth. Three such notches 25a, 25b and 25c are formed. Locking means 26 is arranged on the handle 9 and includes a detent in the form of a transverse rod 27 operatively connected by a stem 28 to a manually operable release member in the form of a button 29. The stem 28 depends from the rod 27 across the tube 11 between the bars 16 and out through an opening 30 in the wall of the tube. One end of the stem 28 screws into the rod 27 normal to the rod and the outer end is secured to the button 29.
The inner surface of the button is formed with a short cylindrical wall 31 co-axial with the stem 28. The wall 31 slides in a cupshaped bush 32 mounted in the opening 30.
A helical spring 33 is carried on the stem 28 and acts between the inner surface of the button and the bush 32 to bias the locking means 26 towards the locking position shown in Figures 5 and 6 in which the rod 27 engages a pair of corresponding notches 25a, one on each of the bars 16, which are adjacent to each other. To move the locking means 26 to the unlocking position (not shown) the button 29 is depressed against the biassing of spring 33 to disengage the detent from the notches 25a. To prevent the rod 27 rotating it is mounted on a rectangular plate 34, the width of which corresponds to the internal width of the tube 11.
As shown in Figure 4 two further links 35, 351 are provided. One end of each of the links 35, 351 is pivotally connected to the midpoint of the links 14, 14' respectively. The other end of each of the links 35, 351 is pivotally connected to brackets 36, 37 res pectively. As shown in Figures 1 to 3 brackets 36, 37 are secured to the panel 4. Links 35, 351 serve to stabilise the panel against tilt. The pivotal connection of each stabilising link 35, 351 to the edge of the panel is substantially opposite the pivotal connection of the associated link 14, 141 to the frame 2.
To move an edge of the panel, for example to open it from the fully closed position shown in Figure 1 the user grasps the handle 9- and presses the button 29 against the spring loading to disengage the rod 27 from the notches 25 on the plungers. He can then use the handle 9 to push the edge of the panel away from the opening 3 by the desired amount either to open the panel fully as shown in Figure 2 or to open it partially as shown in Figure 3. This causes the links 14, 141 to pivot on the frame 2 and the two plungers 15, 151 movie apart. When the desired degree of opening is reached the user releases the button 29 and the spring-loading automatically presses the rod 27 into engagement with the notches 25, a further slight movement perhaps being required to ensure the rod 27 is aligned between a pair of notches, one on each plunger, which are adjacent to each other. The panel is thereafter securely held against movement by wind pressure or vibration, and can only be released by pressing the button once again.
In the embodiment described above engagement of the rod 27 with the notches 25a on the bars 16 corresponds to the fully closed position shown in Figure 1, engagement with the notches 25c corresponds to the fully open position shown in Figure 2 and engagement with the notches 25b corresponds to the intermediate open position shown in Figure 3.
The opposite edge of the panel can be moved simultaneously in similar manner.
However it will be understood that only one edge need be moved at any time and in addition that edge may be moved so that the panel is at an angle relative to the frame, for example by aligning notch 25b on one plunger with notch 25c on the other plunger.
Other similar positions of one or both edges will be obvious and need not be further described.
In a modification (not illustrated) a compression spring is provided in the tube acting to urge the plungers apart, thereby assisting movement in the opening direction and counteracting the weight of the panel.
However where the panel is a lightweight construction such a spring will be unnecessary.
In an alternative construction (not illustrated) each handle and associated control means is substantially similar to that described with reference to Figures 1 to 6.
However each handle is angularly movable by hand about its own axis to operate the associated locking means. The handle therefore corresponds in its action to the button 29 described previously. The handle is preferably spring-urged to the locking position. The locking means has several locking positions so that the associated edge of the panel can be locked in the closed position, the fully open position, and one or more intermediate positions. The locking detent means is formed by a longitudinal slot formed in the hollow interior of the handle, this slot having a series of notches in one edge, and each plunger having a radially projecting pin capable of engaging in a selected one of the notches so as to lock both plungers axially. To move the edge of the panel, for example to open it from the fully closed position, the user grasps the handle and turns it against the spring loading to disengage the pins on the plungers from the notches, then he can use the handle to push the edge of the panel away from the opening by the desired amount. This causes the links to pivot on the frame and the two plungers move apart. When the desired degree of opening is reached the user releases the handle and the spring-loading automatically turns it about its axis to cause the pins to enter those notches that they are then opposite.
The panel is thereafter securely held against movement by wind pressure or vibration, and can only be released by grasping and turning the handle once again.
A compression spring may also be provided within the tube acting to urge the plungers apart, thereby assisting movement in the opening direction and counteracting the weight of the panel.

**WARNING** start of CLMS field may overlap end of DESC **. 35, 351 is pivotally connected to the midpoint of the links 14, 14' respectively. The other end of each of the links 35, 351 is pivotally connected to brackets 36, 37 res pectively. As shown in Figures 1 to 3 brackets 36, 37 are secured to the panel 4. Links 35, 351 serve to stabilise the panel against tilt. The pivotal connection of each stabilising link 35, 351 to the edge of the panel is substantially opposite the pivotal connection of the associated link 14, 141 to the frame 2. To move an edge of the panel, for example to open it from the fully closed position shown in Figure 1 the user grasps the handle 9- and presses the button 29 against the spring loading to disengage the rod 27 from the notches 25 on the plungers. He can then use the handle 9 to push the edge of the panel away from the opening 3 by the desired amount either to open the panel fully as shown in Figure 2 or to open it partially as shown in Figure 3.

However each handle is angularly movable by hand about its own axis to operate the associated locking means. The handle therefore corresponds in its action to the button 29 described previously. The handle is preferably spring-urged to the locking position. The locking means has several locking positions so that the associated edge of the panel can be locked in the closed position, the fully open position, and one or more intermediate positions.
