Description

(54) ROOFLIGHT VENTILATOR ATTACHMENT MEANS (71) We, LUCAS INDUSTRIES LIMITED, a British Company of Great King Street, Birmingham, B19 2XF, 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 attachment means for attaching a ventilator to the roof of, inter alia, a caravan or other vehicle, the ventilator being of the kind comprising a frame or surround which is adapted to be mounted in an aperture formed in the roof together with a transparent lid or panel which is connected to said frame or surround so as to be movable relative thereto between an upper or open position in which air can flow between the panel and the frame or surround and a lower or closed position in which said panel is sealingly engaged with said frame or surround to form a closure therefore. The object of the present invention is to provide an improved form of attachment means.
In accordance with the invention there is provided rooflight ventilator attachment means comprising a housing having a longitudinally extending slot, a first clamping member mounted in said housing so as to be slid able relative thereto, a threaded stud connected to said clamping member and extending through said slot, a channelshaped member which is arranged to embrace the exterior of said housing and having an aperture through which said threaded stud extends, a stay member having an aperture through which the threaded stud also extends, and a second clamping member in the form of a nut which is mounted on that end of the threaded stud remote from said first clamping member, the adjacent surfaces of said channel-shaped member and the stay member being formed with co-acting projections and recesses which, when engaged with each other on tightening of said nut, prevent relative rotation between said stay member and the channel-shaped member, such tightening of the nut being also arranged to bring said first clamping member and said channel-shaped member respectively into frictional engagement with the interior and exterior of said housing to prevent longitudinal movement of the stay member relative to the housing after said first clamping member as been moved to a desired position in the housing.
The invention will now be more particularly described with reference to the accompanying drawing which is an "exploded" perspective view of one example of rooflight ventilator attachment means constructed in accordance with the present invention.
Referring to the drawing the attachment means shown therein is intended for use in attaching a ventilator to the roof of a caravan or other vehicle and includes a housing 10 which is conveniently formed as an integral part of a synthetic resin moulding (indicated by reference numeral 11) which forms the frame or surround of the ventilator. Such frame or surround is conveniently of rectangular configuration in plan and a pair of attachment means would be provided on opposite sides of the frame or surround but since the two means are similar description of one will suffice.
The housing 10 is formed with a longitudinally extending slot 12 which, when the ventilator is in use, will extend in a generally vertical direction. Mounted within said housing for slidable movement along the length thereof is a first clamping member 13 which is conveniently formed of a synthetic resin material and which has on one face a projecting portion 14 of reduced cross-sectional area, said reduced portion 14 extending through the aforesaid slot 12 so that its outer face is disposed outside the confines of said slot. The rear face of that portion of said first clamping member 13 which lies within the housing 10 is provided with a non-circular recess which is adapted to receive the head of a threaded member 15 which extends forwardly through an aperture formed in said member 13 so as to project through the slot 12.Thus by virtue of the interengagement of the head of said threaded member 15 with the non-circular recess in the member 13 said threaded member 15 will be prevented from rotation relative to the member 13.
There is also provided a channel-shaped member 16 formed of a synthetic resin material and provided with an aperture 17 through which in use said threaded member 15 will extend so that the channel-shaped member 16 will be loosely mounted on the threaded member. Furthermore said channel-shaped member 16 is so shaped that it will embrace the exterior of the housing 10 so as to be slidable along the exterior of said housing the two sides of said channel-sahped member 16 acting, in conjunction with the two sides of the housing, to prevent rotation of said member 16.The depth of said sides of the channel-shaped member 16 is however slightly less than the depth of the sides of the housing 10 so that the interior surface of the base portion of said channel-shaped member 16 can be brought into engagement with the outermost surfaces of said housing 10 on either side of the slot 12 without any interference between the surfaces of the frame or surround 11. The interior surface of said base portion of the channel-shaped member 16 is formed with a recess indicated by reference numeral 18 which is adapted to receive and locate that part of the portion 14 which extends through the slot 12 so as to prevent rotation of said member 16 relative to the part 14. The attachment means also includes a stay member 19 which is connected to the panel or lid (not shown) of the ventilator and which has an aperture 20 through which said threaded member 15 will also extend.Finally there is a second clamping member in the form of a nut 21 having an outer rim which is knurled or otherwise shaped to facilitate a grip being obtained by the user and said nut 21 would be screwed onto the outer end of said threaded member 15 after assembly of the above-described parts. In addition the outer surface of the base portion of the channel-shaped member 16 and the adjacent surface of the stay member 19 are formed with co-operating projections and recesses which, when engaged, have the effect of preventing rotation of said stay member 19 relative to the channel-shaped member 16. As shown in the drawings such co-operating projections and recesses comprise serrations 22 moulded on to the channel-shaped member 16 and co-acting serrations 23 moulded into the adjacent surface of the stay member 19.
Thus when the above-mentioned parts are assembled the nut 21 can be loosened on the threaded member 15 to permit movement of the first clamping member 13 along the length of the housing 10 to provide for any desired degree of opening of the panel or lid to which the stay member 19 is connected relative to the frame or surround 11. At the same time the serrations 22 of the channelshaped member 16 can be disengaged from the serrations 23 of the stay member 19 to permit of any desired angular setting of the stay member 19 (and hence the lid or panel as well) relative to the frame or surround 11.
The nut 21 is then tightened to bring the aforementioned serrations into register so as to prevent any further angular movement of the stay member 19 and also to clamp the whole assembly together in a condition in which the inner part of the first clamping member 13 is brought into frictional engagement with the interior of said housing 10 whilst the interior of the base portion of said member 16 is brought into frictional engagement with the exterior of said housing 10. This will prevent any further movement of the assembly along the length of the housing 10 and of course the stay member 19 will be firmly located between the channelshaped member 16 and the nut 21.
In the position illustrated in the drawing the attachment means is shown as being at the upper end of the housing 10 so that the panel or lid of the ventilator will be in its fully open position and in order to prevent any undue loading (as for example wind loading on the panel or lid) being taken by the aformentioned serrations, the upper edge of said frame or surround 11 may be conveniently provided with abutment means in the form of an overhanging lip 24 which will engage a part of the upper surfaces of the sides of said channel-shaped member 16.
WHAT WE CLAIM IS: 1. Rooflight ventilator attachment means comprising a housing having a longitudinally extending slot, a first clamping member mounted in said housing so as to be slidable relative thereto, a threaded stud connected to said clamping member and extending through said slot, a channelshaped member which is arranged to embrace the exterior of said housing and having an aperture through which said threaded stud extends, a stay member having an aperture through which the threaded stud also extends, and a second clamping member in the form of a nut which is mounted on that end of the threaded stud remote from said first clamping member, the adjacent surfaces of said channel-shaped member and the stay member being formed with co-acting projections and recesses which, when engaged with each other on tightening of said nut, prevent relative rotation between said stay member and the channel-shaped member, such tight

Thus by virtue of the interengagement of the head of said threaded member 15 with the non-circular recess in the member 13 said threaded member 15 will be prevented from rotation relative to the member 13. There is also provided a channel-shaped member 16 formed of a synthetic resin material and provided with an aperture 17 through which in use said threaded member 15 will extend so that the channel-shaped member 16 will be loosely mounted on the threaded member. Furthermore said channel-shaped member 16 is so shaped that it will embrace the exterior of the housing 10 so as to be slidable along the exterior of said housing the two sides of said channel-sahped member 16 acting, in conjunction with the two sides of the housing, to prevent rotation of said member 16.The depth of said sides of the channel-shaped member 16 is however slightly less than the depth of the sides of the housing 10 so that the interior surface of the base portion of said channel-shaped member 16 can be brought into engagement with the outermost surfaces of said housing 10 on either side of the slot 12 without any interference between the surfaces of the frame or surround 11.

The attachment means also includes a stay member 19 which is connected to the panel or lid (not shown) of the ventilator and which has an aperture 20 through which said threaded member 15 will also extend.Finally there is a second clamping member in the form of a nut 21 having an outer rim which is knurled or otherwise shaped to facilitate a grip being obtained by the user and said nut 21 would be screwed onto the outer end of said threaded member 15 after assembly of the above-described parts. In addition the outer surface of the base portion of the channel-shaped member 16 and the adjacent surface of the stay member 19 are formed with co-operating projections and recesses which, when engaged, have the effect of preventing rotation of said stay member 19 relative to the channel-shaped member 16. As shown in the drawings such co-operating projections and recesses comprise serrations 22 moulded on to the channel-shaped member 16 and co-acting serrations 23 moulded into the adjacent surface of the stay member 19.
