ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to the field of bolt covers and in particular to a cover made of plastic or similar materials that are softer than metal in order to provide a safe covering for bolts and other hardware that extends from construction projects.
It is observed that in many urban building projects, temporary scaffolding is erected near the street, typically on the sidewalk and the exposed hardware poses a danger to passers by that may cut themselves or their clothing on the hardware. Such pieces such as metal bolts and nuts that secure the scaffolding are typically used on such construction projects. Such members pose a danger to passers by as arms or body may get caught on the bolts causing damage to the skin or clothing. Because of this it is necessary to cover any such hardware up to five or six feet from ground level as this is the height of people who may be injured by the bolts.
It is believed that by covering such hardware pieces with a soft covering as described herein this will protect passers by from the dangers of such hardware. Any construction project that uses such hardware may find use for the invention.
2. Description of the Prior Art
While there are bolt covers in the prior art, none of them use readily available coverings that are found on containers. Nor do they have apertures to accommodate the bolts so as to allow the bolts to protrude through the top of the cap. Moreover, none of the prior art coverings are known to be directed to the idea of covering the bolts in order to make them safe for passersby. Other prior art methods that are used to cover such hardware include duct tape and similar materials. Such coverings may be used on an ad hoc basis in order to cover bolts and nuts. This is assuming that the construction workers bother to go to the trouble of covering the bolts with such.
There are several disadvantages to using tape. Tape can be expensive and is certain to be more time consuming than the cap described herein. Wrapping such tape over and around the bolt is bound to take more time than using the cap described herein. Another time factor involves the dismantling of such projects because such tape may have to be cut with shears when the project is over and the scaffold needs to be dismantled. Using the cap will eliminate time involved in both placing the coverings and dismantling when the project is over. The cost of the cap should be as expensive or perhaps less expensive than the duct tape method. Using caps that have already been sold in the retail business will also help to decrease the cost of the covering.
SUMMARY OF THE INVENTION
The invention is a plastic safety cover for covering bolts and similar hardware items that may extend from construction projects such as building scaffolding. The invention may be made by recycling already existing plastic caps or small bottles found in the retail sales and making minor modifications to them. The invention comprises a cylindrical shaped plastic member having an upper wall in order to close off one side of the cylinder. The cap is designed to be used to cover bolts etc. that extend outward from buildings. The upper wall should have an aperture cut or otherwise created in order to accommodate the bolt that may protrude through this wall. The cover should have a series of weep holes in order to permit drainage of water from the cover due to precipitation.
It is an object of the invention to provide a safe covering for bolts and other hardware that would otherwise pose a danger for pedestrians who pass by scaffolding used on urban construction sites.
Another objective is to provide a safe covering for hard ware such as bolts and nuts that can be use by retooling readily available plastic covers sold as part of retail products.
Another objective is provide safety covers for bolts and other hardware that can be easily and inexpensively made from existing plastic materials that are readily available.
Another objective is to provide a safe covering for hardware such as bolts and nuts that can be quickly and more easily applied to the hardware than existing covering methods, such as covering with duct tape.
Another objective is to provide a covering to protect underwater structures such as scaffolding and the like that have metal hardware such as bolts and nuts that would otherwise be subject to corrosion and other deteriorative effects.
Other advantages of the invention should be readily apparent to those skilled in the art once the invention has been described.
