Description

(54) A BLIND ASSEMBLY (71) We, STOWAGE L1MITED, a British Company of 44 Leicester Road, Lough- borough, Leicestershire, 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 present invention relates to a blind assembly particularly a blind assembly for use in covering windows of a vehicle such as a motor car or yacht.
According to the present invention there is provided a blind assembly comprising a blind attached at one end to a roller and at the other end to an anchoring member, the roller being rotatably supported on a frame including an elongate body portion having shaft portions formed at both ends which are axially aligned and upon which the roller is rotatably received with the shaft portions extending axially within the roller, the frame and the anchoring member having attach ment means for releasibly attaching them to a smooth surface, the roller being biased in a given rotational direction for wrapping of the blind therearound.
Reference is now made to the accompanying drawings in which: Figure 1 is a side view of a first embodiment according to the present invention; Figure 2 is a side view of a second embodiment according to the present invention; Figure 3 is a schematic side view of the second embodiment of Figure 1 shown in use.
The blind assembly 10 shown in Figure 1, comprises a roller 11 rotatably mounted in a frame 12. The roller 11 is preferably a hollow tube made from a light material, for instance, an extruded light metal alloy or plastics material or a cardboard tube preferably made from wound strips of card.
In each end of the tube there is received a cap member 13 each of which has a central bore 14 for receiving end portions 15a, 15b of frame 12. Conveniently, both cap members are moulded from a plastics material.
End portion 15a of frame 12 is longer than end portion 15b and supports a spring 17 which is preferably conical in shape. The narrow end of spring 17 is anchored to end portion 15a preferably by crimping the spring into a flattened portion 18 of the end portion 15a. The opposite, wider end of the spring 16 is anchored to the cap member 13 through which end portion 15a extends by virtue of a terminal projection 19 of spring 17 being received in a bore 20 formed in the cap member 13. Consequently, relative rotation between the roller 11 and frame 12 tensions the spring 17 so that on release of the roller it rotates back to its original position under the bias of the spring.
The end portions 15a and 15b of frame 12 are connected to one another by an elongage rod portion 22 which extends parallel to the axis of rotation of the roller. The rod portion 22 slidably receives two suckers 25 (Figure 1) each of which have a base portion 25a having a transversely extending bore through which rod portion 22 extends.
The blind 30 is attached at one end to the roller 11 for instance, by adhesive and/or staples and is wrapped therearound. The other end of the blind is attached to an anchoring member 32. In Figure 1, the anchoring member 32 comprises a rod 33 which extends, laterally of the blind 30 and has end portions 34, 35 which project beyond respective side edges of the blind. A sucker member 36 is received on each end portion 34, 35. The sucker members 36 have a boss portion 37 which has a laterally extending groove or bore for receiving the respective end portion. The terminal end of each portion 35 is conveniently covered by an end cap 34a, 35a respectively, the end caps being moulded from a suitable plastics material.
The anchoring member 32 is also provided with a lateral projection 33a which is located centrally of the rod 33 and which serves as a finger grip. The end of the blind is either wrapped or looped above rod 33 and secured for instance by adhesive. The blind 30 may be made from a heavy duty paper which may be coated with a plastics material or may be made from an opaque plastics sheeting.
Preferably the blind is made from a sheet of bonded high density polyethylene fibres such as that commercially obtainable from the Du Pont Company under the trade mark TYVEK The sucker members 25, 36 are made of suitable plastics material or an elastomeric material such as rubber. Preferably they are made from polyvinylchloride which is obtainable from the I.C.I. Company under reference 18/810 and has a Shore Hardness of 55A.
The embodiment illustrated in Figure 2 has the same blind and roller construction as that of the Figure 1 embodiment and basically illustrates a modified construction for securing suckers to frame 12 and anchoring member 32. Thus, in the Figure 2 embodiment the end portions 34, 35 of the rod 33 are bent so as to form portions 34b, 35b which are directed to one another and onto each of which there is received a sucker 35. If desired, as illustrated in broken lines, portions 34b, 35b may be extended to meet one another in which case a single sucker 36a may be employed instead of the other two suckers 36.
Of course, if desired all three suckers. may be incorporated.
In Figure 2 suckers 25 are secured to frame 12, by means of the provision on the rod portion of two laterally extending projections 23, 24 each of which are preferably threaded.
A sucker member 25 is received on each projection. The projections 23, 24 are are conveniently hooks which are slidably received on the rod portion 22 so that the spacing between the sucker members 25 may be varied as desired. Alternatively, if desired, projections 23, 24 may be formed from screws which are secured to the rod portion for instance by soldering.
In use as the blind is unwrapped from roller 11, the spring 17 is tensioned and on release of the blind the spring 17 rewinds the blind around the roller 11 until anchoring member 32 engages the frame 12.
Both frame 12 and anchoring member 32 are conveniently made by bending metallic rods but it is envisaged that rods of plastics material may also be used if desired.
In use, as shown in Figure 3, the frame 12 is attached to the windscreen 40 of a vehicle, for instance, a motor car, yacht etc., by virtue of sucker members 25. The blind 30 may then be drawn across the windscreen and held in its extended position by virtue of sucker members 36, and/or 36a. Thus the blind serves to prevent penetration of the sun's rays into the interior of the vehicle. Advantageously, at least the surface of the blind facing the exterior of the vehicle may be treated so as to be reflective. Additionally, this surface may also be printed with advertising literature.
Thus, the present invention provides a blind assembly for a vehicle which is light in weight and cheap to produce.
