Description
The present invention relates to head gear and, in particular, to a hat for use in maintaining ~he vicinity of the body of a wearer free from insects or cooling the upper body of the wearer as desired.
According to the present in~ention therefore, there is provided a hat for use in maintaining the vicinity of the body of a wearer free from insects or cooling the upper body of the wearer as desired, comprising an outer shell and an inner shell disposed inside the outer shell, defining a space between the shells/ fan means being disposed in said outer shell so as on activation to create a flow of air in said space between said shells, power source means adapted to drive said fan at a high speed to provide a flow of air completely over the body of the wearer to remove any insects in the vicinity of the wearer or at a lower speed to provide a flow of air over the upper body of the wearer and nozzle rneans adapted to direct the air from said fan exiting from said hat around said bod~ of said wearer.
Suitably, the power source is a battery located in the hat preferably so as to be at the back of the wearer's head, the ~0 fan means comprising a fan disposed in the hat so as to be on top of the wearer's head. The fan is desirably a dual speed fan unit.
Thus, the present invention is based upon the concept of using a two--speed battery powered fan in a helmet cover especially designed to produce air by deflection. When run at high speed a balloon or cone of air is projected sufficiently far with sufficient strength to keep bugs away from the body in bug infested climates and, when run at a low speed a gentle flow of air is projected on the face and o~ the upper body to cool the body in hot weather, and thus the hat is essentially a portable outside air conditioner. ~he battery unit is suitably ~,~
placed above the neck at the back of the head and connected to the fan unit which is suitably on the top of the head~ The fan is desirably a noiseless, very light wei~ht fan, suitably made of plastic, with a size and number o~ blades suitable for use in such a hat, combined with the hat design cover, in co-ordination ~ith the pitch and speed of the fan blades. A
balloon or a cone of air projected far enough, for example, 6 to ~ feet, keeps the bugs away from the head to the toe of the person wearing the hat, and, with a small flow of air at the top of the head to protect the body from top to bottom and around without air-flow on the face. A balioon o~ air can be produced by deflection on the shells of the hat to create multiple forces of air, set up in such a way that it will make inter-crossing twisted air-vents that will make a whirlwind of airflows that -the bugs cannot fight. Alternatively, a cone of air will be produced by deflection of the air between two shells of the hat creating multiple air cones having a downward direction.
The hat is suitably a helmet which is set up to fit and can be put in place very quickly. Essentially all that is re~uired is putting on of the hat and wearing the hat as a conventional one. The hat is no more cumbersome than a conventional hat. The battery is suitably placed vertically ~t the back of the head, although it may be a little large in size it does not feel heavy on the headO Thus, it will be recognized that the hat of the present invention is useful in many countries of the world sufferin~ from bugs and, is part-icularly of use to fishermen, golfers, gardeners, farmers, and children playing outdoors, who come into contact with such bugs.
At the present time insecticides are in general use which are undesirable. The hat of the present invention is very useful in hot countries and may be used both ways, i.e., at times as a bug chaser and, at times as an air-conditioner. It is essential,

At the present time insecticides are in general use which are undesirable. The hat of the present invention is very useful in hot countries and may be used both ways, i.e., at times as a bug chaser and, at times as an air-conditioner. It is essential,
- 2 -of course, that the hat includes a shell to protect the hair and fingers catching the blades of the fan in any possible fashion.
When used as an air conditioner, using the low-speed fan, the low speed fan will generate a small flow of air on the face and on thc upper body of the person to cool off in hot weather. It is, of course, possible to have separate fan units connected to the same battery unit to provide the high-speed and low-speed fans.
The battery used in driving the fan is desirably small and light as possible and/ desirably no bigger than five inches in len~th and two inches in width and, may be as deep as three-quarters of an inch at the bottom to a quarter of an inch at the top and, curved in such a way to fit the back of the head above the neck as close as possible. This allows less weight on the back of the head. However, the battery must be powerful enough to power the fan as long as possible, desirably from six to eight hours or more, before it requires recharging, automatically or on a rechargeable unit. A set of batteries can, of course, be used. The hat can be held on the head by adjustable plastic straps devised to fit the head. The hat should be shaped around 2Q the head and down both sides to permit the wearer to place the fan and the battery in the place which feels most comfortable.
The present invention will be further illustrated by way of the accompanying drawings in which:
FIG. 1 is a side view of the head of the wearer of tihe hat;
FIG. 2 is a plan view of the hat o~ Figure l;
FIG. 3 is a similar view to Figure 1 with the head removed and partially broken away to show the operation of the fan.
Referring to the accompanying drawings, the hat 1 is held on the wearer's head by the strap 2 and, comprises an outer shell 3 and an inner shell 4, separated by equi-spaced struts 5 for rigidity. The outer shell 3 has air-intakes 6 secured against bug entry, disposed above a 2-speed fan 7 including a motor 8 so as to force air between through the passage 9 between the ou~er and inner shells 3 and 4, and over the wearer's face and body as required. The fan is driven from batteries and is controlled by a three position twist switch 11 which in a first position switches the fan 7 off, in a second position the fan is driven at low speed and, in a third position the fan is driven at high speed. Such switches 11 are well known in the art~
