ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a hinged connection between a removable housing closure and a stationary housing part. Such housings are used in particular in automatic pivot-hung doors or in drive systems for hinged doors.
In at least one embodiment, the present invention further relates to an automatic door or partition system having hanging partitions or hinged doors. The system utilizes a hinged connection for a removable housing closure or access panel.
2. Background Information
German Patent No. 94 19 652 U1 describes a latch mechanism for the connection of two halves of a suitcase. The latching mechanism is realized in the form of a hinged system and in particular in the form of a hinged catch. This hinged catch can be locked and unlocked. The hinged catch thereby has a snap-in bulb that is realized in the form of a molded-on ball that can be engaged in mating snap-in bulbs.
In a product catalog published by Schuco International, various door profiles are illustrated as part of the Royal S 55 series. This catalog also shows profiles that have a projection in which there is a continuous boring, but which at one point has an opening in the side wall. Gaskets, in particular brush gaskets made of Perlon fibers, or door closing profiles in the form of rubber strips can be inserted in such profiles, which are specifically designated latching profiles.
On equipment paneling, in particular of the type described above for automatic doors, problems are frequently encountered when opening these panels because they are generally several meters long and are usually located above the pivoting or rotating panels of the door. For example, the folding part of the housing is extraordinarily difficult for an installer to handle, both during removal and replacement of the panel.
OBJECT OF THE INVENTION
The object of the present invention is to substantially eliminate the deficiencies of similar devices of the known art, and specifically to create an easy-to-operate and simultaneously substantially unseen or invisible, long-lasting, hinged connection between a removable housing closure and a stationary housing part.
It must thereby be possible not only to pivot the removable housing part, but also to remove it in its entirety from the stationary housing part without the need to use tools. In addition, no projecting parts should be visible either in the interior of the housing or on the outside.
SUMMARY OF THE INVENTION
The present invention teaches that this object can be accomplished by a terminal configuration of the housing closure that can have a convex molding, with a web that is contiguous with the molding and has a tapering cross section. Contiguous with the web there can be an indentation, in which a convex molding that is on the stationary housing part and is offset by an angle of approximately 90 degrees with respect to the molding can be engaged by means of a contiguous web that has a tapering cross section. The housing closure thereby can be pivoted with respect to the stationary housing part and re-engaged with it. Additional configurations of at least one embodiment of the present invention are described in the features hereinbelow.
The present invention teaches a special terminal configuration both of the movable and removable housing closure and of the stationary housing part. On the housing closure, there can be a convex molding that can have a spherical head, for example, whereby contiguous with this head there is a tapered part of the material, i.e. there is a leg or a web that is thinner than the convex molding. In a continuation of the above mentioned web, and contiguous with it, there is an indentation in the profile which can serve as a receptacle for a piece that is molded onto the stationary housing part but can be offset at an angle of approximately 90 degrees with respect to the removable housing part. This molded-on part can also be realized in the shape of a ball, and contiguous with it there is a web or a tapered portion, just as on the removable housing closure. The tapered portion emerges into a web or leg of the stationary housing part, which web or leg is offset at an angle of approximately 90 degrees, whereby on this stationary housing part there can also be an indentation that is realized so that the spherical molded part of the removable housing part can be engaged in it. To achieve a substantially noiseless mechanism as well as a solid and secure seating of both parts, i.e. of both the stationary housing part and also of the removable housing closure, the convex moldings can be provided, at least in partial areas, with a covering made of plastic. When the removable housing part is inserted into the indentation and is pulled down, it can be essentially guaranteed that the two housing parts will be hooked to each other, which produces a positive connection, and, with the application of a small amount of force, also a non-positive connection. The housing parts can preferably be fabricated from aluminum or from an aluminum alloy.
The above discussed embodiments of the present invention will be described further hereinbelow with reference to the accompanying figures. When the word “invention” is used in this specification, the word “invention” includes “inventions,” that is, the plural of “invention.” By stating “invention,” the Applicant does not in any way admit that the present application does not include more than one patentably and non-obviously distinct invention, and maintains that this application may include more than one patentably and non-obviously distinct invention. The Applicant hereby asserts that the disclosure of this application may include more than one invention, and, in the event that there is more than one invention, that these inventions may be patentable and non-obvious one with respect to the other.
