The bracket (4) performs all functions which in the past were carried out by several distinct connection and support elements.
Description
~UVO 95132912 PCTlll94/00164 -~,~' ~~: 2191720 A Multifunction Connection and Support Element in a Mechanism for Automatic Door Motion for Lifts and Elevators.
Description.
The invention relates to a multifunction connection and support element in a mechanism for automatic door motion for lifts and elevators.
Known-type lifts generally comprise two lateral 05 jambs and a transversal superior element, or architrave, which connects the two jambs (for example by bolting) and houses the motion mechanism of the lift doors.
The architrave is provided with means for anchoring to a fixed wall of the lift shaft, which means for anchoring are constituted by brackets bolted to the architrave in the central zone thereof and fixed to the wall by screws.
Internally of the architrave there are also supports for the guides of the door motion mechanisms, which supports are completely separate ' from the above-mentioned screws and are not applied thereat.
The principal drawback of the above realizations is the need to arrange a large number of W0 95132912 PCT11f94100164 ..~ 2191720 connection or support elements for fixing the various components of the door and for the support of the guides of the movement carriages of the doors.
OS A further drawback is that the numerous connection and support elements are positioned rather distributedly along the architrave, which can lead to slight bending thereof.
The main aim of the present invention is to f0 obviatz the above drawbacks by providing a multifunction connection and support element able efficiently to perform the functions of numerous elements employed in the prior art, and also able better to stiffen and strengthen the door 15 structure.
The above aims are fully attained by the multifunction connection and support element, object of the present invention, which is characterized as set out in the accompanying 20 claims and in particular in that it consists of a connection and support bracket for each lateral door jamb, which contemporaneously connects and unites the jamb with the architrave as well as with the means for anchoring the architrave to a 25 fixed wall.

The above aims are fully attained by the multifunction connection and support element, object of the present invention, which is characterized as set out in the accompanying 20 claims and in particular in that it consists of a connection and support bracket for each lateral door jamb, which contemporaneously connects and unites the jamb with the architrave as well as with the means for anchoring the architrave to a 25 fixed wall.
The bracket preferably also supports the sliding guides of the door motion carriages.
In a further aspect of the invention a multifunction connection and support element in a 5 mechanism for automatic door motion for elevators, comprising two lateral jambs and an architrave which connects the two jambs and which houses motion mechanisms of doors of an elevator, said architrave being constrained by 10 anchoring means to a fixed wall in an elevator shaft in which the elevator moves up and down, wherein the multifunction connection and support element consists of, for each lateral jamb, a connection and support bracket which connects 15 and unites the jamb with the architrave and the anchoring means.
In another aspect of the invention a multifunction connection and support automatic door apparatus for use with an elevator door opening in a wall of 20 an elevator shaft comprising: a pair of laterally spaced jambs for positioning at opposite sides of a door opening in a wall of an elevator shaft; an 3a architrave for coupling upper ends of said jambs;
a means for moving housed in said architrave for operating at least one elevator door; an elevator door mounted for movement in the door opening 5 and connected to said means for moving; an anchoring means for coupling to said architrave and for attachment to the wall of the elevator shaft at the door opening; and at least a pair of connection and support brackets attached to and 10 coupling said jambs with said architrave and said anchoring means.
Further characteristics and advantages of the present invention will better emerge from the detailed description that follows, of an 15 embodiment of the invention, illustrated in the form of a non-limiting example in the accompanying drawings, in which:
