Description

(54) VENTILATING NOZZLE (71) We, CLEARPLAS AND VACUUMET LIMITED, a British Company3 of Bayton Road, Exhall, Coventry, West Midlands, 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:: The invention relates to a ventilating nozzle and is particularly concerned with a ventilating nozzle of the kind (hereinafter called the "kind described") comprising a housing defining an air flow passage extending therethrough between an inlet and an outlet, the outlet being of rectangular shape (which term includes "square"), the housing containing a deflector vane assembly mounted for turning about an axis of rotation parallel to a pair of opposite sides of the outlet, the vane assembly including a set of spaced deflector vanes each extending parallel to the axis of rotation between a pair of end walls, the deflector vanes defining therebetween an air flow path through which air will flow in its passage through the housing, angular adjustment of the vane assembly about the axis of rotation thereof determining the direction radially of the axis of rotation of the vane assembly in which the air flow will issue from the housing.
One known ventilating nozzle of the kind described which is suitable for mounting in the fascia of a motor vehicle to ventilate the interior of the vehicle includes a vane assembly in the form of a generally cylindrical barrel having end walls which are provided with trunnion mountings by which the barrel is rotatable in the housing and between which the set of vanes parallel to the axis or rotation of the barrel extend. The trunnion mountings may either be spigots extending outwardly from the end walls of the barrel and engaged in holes or sockets in adjacent walls of the housing or they may be spigots extending from the housing walls and engageable in holes or sockets in the end walls of the barrel.The spigots must have sufficient running clearance in the holes or sockets and there must also be axial clearance between the end walls of the barrel and the adjacent housing wall to enable the barrel to be turned about its axis of rotation.
However if too much freedom of movement is provided, the barrel could turn from a position to which it has been set, as a result of vibration, especially where the nozzle is mounted in a motor vehicle, The known vane assembly also has a second set of parallel vanes extending transversely to the axis of rotation of the barrel and which can be orientated with respect to the first-mentioned set of vanes to effect deflection of the air flow issuing from the outlet of the housing in directions toward one or other end wall of the barrel. However, the present invention is not restricted to a ventilating nozzle having a barrel having the second set of adjustable vanes in addition to the first-mentioned set of vanes.
According to the present invention, a ventilating nozzle of the kind described includes a resilient clip which engages the vane assembly and holds one of the end walls of the vane assembly in light rubbing contact with an adjacent wall of the housing, by moving the vane assembly in the housing in the direction of the axis of rotation of the vane assembly, the vane assembly having sufficient clearance between its end walls and the adjacent walls of the housing to permit this movement and the bias provided by the clip permitting manual turning of the vane assembly about the axis of rotation but providing sufficient resistive torque to hold the vane assembly from unintentional turning movement about the axis of rotation.
In one arrangement in accordance with the invention, the resilient clip may be of general U-shape having a bight which is passed through an aperture in an end wall of the housing at a position radially beyond the periphery of the vane assembly and a pair of limbs arranged to bear one against the outside of the said end wall of the housing and the other against the inside of the adjacent end wall of the vane assembly, the two limbs being urged by the resilience of the clip toward each other into contact with the respective walls of the housing and the vane assembly.
In another arrangement in accordance with the invention, the resilient clip may be mounted on a wall of the housing by a mounting portion and has a resilient leaf integral with the mounting portion and which is arranged to bear against the inside of an end wall of the vane assembly adjacent the wall of the housing on which the clip is mounted to urge the vane assembly axially towards the adjacent end wall of the housing. The mounting portion of the clip may be of U-shape and be capable of fitting snugly over an edge of the housing wall.
In yet another arrangement, where two vane assemblies are positioned end-to-end in a housing having an internal wall intermediate the two vane assemblies and which provides a trunnion mounting at adjacent ends of the vane assemblies, the trunnion mountings at the other ends of the vane assemblies being provided by the outer walls of the housing adjacent the respective ends of the vane assemblies, the resilient clip may be of U-shape and have a bight which bridges the internal wall between the vane assemblies and limbs which engage the respective inner faces of the adjacent end walls of the two vane assemblies, the two limbs of the clip being urged by the resilience of the clip toward each other and into contact with the respective end walls of the vane assemblies.
In each of the three arrangements, the resilient clip may be made of springy metal strip or wire or it may be made from a resilient plastics material.
The or each limb or the leaf of the clip which bears against an end wall of a vane assembly may have a rounded protuberance or protuberances, thereby to make substantially point contact with the respective end wall of the vane assembly to permit rotational adjustment of the vane assembly.
Three alternative clips in a ventilating nozzle of the kind described are now described by way of example with reference to the accompanying drawings, in which: Figure 1 is a front elevation of the ventilating nozzle having a rectangular cross section; Figure 2 is a longitudinal section on the plane II-II through the nozzle shown in Figure 1; Figure 3 is a transverse section on the plane III-III in Figure 2, and Figures 4 and 5 are portions of Figure 2 showing two alternative forms of resilient clip.
Referring to Figures 1 - 3, the housing comprises side walls 1 and 2 and longitudinal walls 3 and an intermediate internal wall 5 parallel with the side walls 1 and 2. The inlet to the housing is shown at the bottom of Figures 2 and 3 and the outlet is in the form of a rectangular mouth 4.
The housing contains a pair of vane assemblies each in the form of a generally cylindrical barrel and comprising a first set of longitudinal parallel vanes 6 and a second set of transverse vanes 7, the latter being mounted to be swivelled relatively to the longitudinal vanes 6 by means of a button 25 mounted on one of the vanes 7 of each barrel and a link 8 by which the vanes 7 in each barrel are interconnected.
The barrels are mounted for turning about a common axis of rotation parallel to the vanes 6 and also to the longitudinal walls 3 of the housing and to the longitudinal sides of the rectangular mouth 4. The axis of rotation is provided by trunnion mountings comprising spigots 9 on end walls 10 of the barrels and engaged in holes or sockets in the respective housing side walls 1 and 2 and in the intermediate internal wall 5. Alternatively the walls 1,2 and 5 may be provided with spigots engageable in holes or sockets in the end walls 10 of the barrels.
The barrels are turned about their common axis of rotation by finger engagement by the user of the respective vane assembly through the mouth 4 of the housing. To permit the vane assemblies to be turned by finger pressure, the spigots 9 make running clearance in their respective holes or sockets and also there must be sufficient end clearance between the end walls 10 of the barrels and the respective housing side walls 1 and 2 and the common intermediate wall 5. An object of the present invention is to provide a ventilating nozzle having resilient clips which will provide sufficient torque resistance to prevent unintentional movement of the barrels from the angular positions to which they have been set and which could occur as a result of vibration. Three alternative resilient clips are illustrated.
The first form of clip, shown in Figure 2, is for use to urge the two barrels into light rubbing contact with the respective sides of the common internal wall 5 of the housing. The clip is of U-shape and comprises a bight 19 which bridges the wall 5, and limbs 20 and 21, which are urged by the resilience of the clip to engage the inner faces of the respective end walls 10 of the barrels. The limbs 20 and 21 have protuberances 22 thereon which engage the respective end walls 10 with substantially point contact to permit the barrels to be turned by the user relatively to the limbs 20 and 21. The resilience of the clip is sufficient to urge the two barrels axially toward each other to bear lightly against the common wall 5 to prevent inadvertent turning of the barrels but does not exert a sufficiently great resistance to prevent turning of the respective barrel by the user.
Referring to Figure 4, the second form of clip is of U-shape and has a bight 11 which is passed through a hole 12 in the side wall 1 of the housing, a first limb 13 wich engages against the outside of the side wall 1 and a second limb 14 which engages against the inside of the adjacent end wall 10 of the barrel. The resilience of the clip is such that the limbs 13 and 14 are urged toward each other to hold the end wall 10 of the barrel against the side wall 1 of the housing to provide sufficient torque resistance to prevent unintentional movement of the barrel but insufficient resistance to prevent positive turning of the barrel by the user. To permit the turning of the barrel by the user the limb 14 has a pair of protuberances 15, each providing substantially point contact with the movable end wall 10.
The third form of clip is shown in Figure 5.
The clip has a mounting portion 16 of U-shape which makes a snug fit on an edge of the end wall 2 of the housing. The mounting portion 16 has an integral leaf 17 having point contact protuberances 18, like the protuberances 15 of the second clip. The clip is sufficiently resilient to cause the leaf 17 to make contact with the respective end wall 10 of the barrel and to urge that end wall into light rubbing contact with the adjacent side wall 2 of the housing, thereby to prevent inadvertent turning of the barrel from a position to which it has been set without preventing positive turning of the barrel by the user.
In each case the clip may be made of a springy metal or wire or of a resilient plastics material.
The clip shown in Figure 1 is intended to be used alternatively to either of the clips shown in Figures 4 and 5, where the clips shown in Figures 4 and 5 are used, one type may be used at one side of the housing and the other at the other side of the housing or both clips used may be of the same kind.
Although a housing containing a pair of rotatable barrels has been illustrated, either of the types of clips shown in Figures 4 and 5 may be used in a housing containing only one barrel, the clip selected being provided at one end only of the single barrel.
As each form of the clip, by imparting endwise loading of the barrel in the housing, provides a resistance to turning, a specific torque resistance can be imparted by using a clip having a spring rating such that the clip will hold an end wall of the barrel against an adjacent housing wall with an endwise force necessary to provide the specific torque resistance and to maintain that torque resistance despite variations in the dimensions of the barrel relative to the housing due to change in temperature or other working conditions.
