ABSTRACT:
BACKGROUND OF THE INVENTION
This invention is used in the field of plastic molding used to cover electrical components. Specifically, the present invention is used in the field of plastic molding used as a base stand for a computer terminal, or other terminal. The present invention is directed toward the problems of inefficient production and assembly of terminal base stands. More specifically, the present invention overcomes the problems of inefficiency and high costs when using numerous screws, or snaps to fit plastic molding components together during assembly of a base stand.
Manufacture of interconnected plastic molding to serve as a housing or cover for sensitive components can be frustrating for the worker due to the tremendous amount of time it can take to fit and secure pieces of molding together. The housing protects electrical components from exposure to dirt, liquid, or other things that are harmful to delicate circuitry. The housing also covers unsightly circuitry from the user's view. The housing must therefore be cosmetically appealing, and sturdy. Because of the need for these attributes, the plastic molding parts are attached with numerous screws in out of sight, and often difficult to reach places. Thus, difficulties for the assembler are common.
Because the housing is used to cover electrical components, the housing is often exposed to vibrations. When screws are used as securers for plastic molding pieces, vibrations can loosen the screws over an extended period of time. It is therefore an object of the present invention to overcome the problem of eventually loosened plastic molding pieces due to vibrations of electrical equipment.
Another problem that occurs when using screws as securers is the excessive amount of time that it takes to assemble the plastic pieces together. The larger the pieces to be secured together, the more screws that are required, and the more work that needs to be done by the assembler. The excessive amount of work is frustrating for the person assembling the computer terminal base or other plastic housing. It is therefore another object of the present invention to provide plastic molding that is quickly assembled with few securing parts.
SUMMARY OF THE INVENTION
The above-described objects and others are met by a housing for protection and containment of electrical components. The housing includes a cover that has at least one hinge hook, and no more than two securing receivers. In a preferred embodiment of the invention, the hinge hook is located on an outer edge of a surface of the cover.
The housing also includes a main body, in which the electrical components are to be enclosed. The main body can be a plastic base stand for a computer monitor. The main body has no more than two securing receivers, like the cover, and a receiver for each of the hinge hooks. When the hinge hooks are in place with the hinge receivers, the securing receivers in the cover automatically align with the securing receivers in the main body.
The housing also includes no more than two securers, received by the first and second securing receivers. The securers can be screws or equivalent fasteners, and the first and second securing receivers can be bosses for said screws or equivalent fasteners. Because of the unique usage of a hinge mechanism in the present invention, the maximum number of required screws and bosses are greatly reduced in comparison with the prior art. There can even be less than two screws and bosses to securely fasten the cover against the main body.
In another embodiment of the invention, a securing clip is mounted on the cover, which can be fastened in a slot formed in the main body when the hinges are engaged with the hinge slots. In such an embodiment, the number of screw required to securely fasten the cover to the main body can be one, or even zero. In this embodiment, the means for snapping the cover against the main body are not limited to a clip and slot. Other equivalent mechanisms for the same purpose can be readily adapted to protect the electrical boards and other electrical equipment to be housed within the main body.
The above-described needs are also met by a method for housing electrical components located in a computer terminal base stand, including the steps of providing a cover, including at least one hinge hook, and no more than two securing receivers; providing a main body, which contains the electrical components to be protected, including no more than two securing receivers, and at least one receiver corresponding to the provided hinge hooks; attaching each hinge hook to each receiver; aligning each of the securing receivers in the cover with the securing receivers in the main body; and attaching a securer through the aligned securing receivers. Using this method, the maximum number of securers and securing receivers may be as few as one.
The above method can further include the steps of mounting a clip or other snapping means on the cover; mounting a slot for receiving the clip on the main body; and clipping the clip into the slot. When these steps are included in the method, the maximum number of securers, and securing receivers may be as few as zero.
