Abstract

Leading optical safety edge safety device, which can be installed on the various new door construction without additional constructive expenses, but also on existing gates and a casserole function has characterized in that it consists of an outer housing and an inner housing, wherein the inner housing by means of a spring and an associated guide is moved out of the outer housing, and at the outer end has a photocell, which performs the function of a leading monitoring below the door leaf.

Description

The Invention has a one-way light barrier system consisting of transmitter and receiver, as optical closing edge safety to the content, whose active light beam is at a distance in front of the Torunterkante including the rubber floor seals on the outer door sides is mounted and thus "leading" Obstacles when closing the gate can detect and is mechanically retracted at the closed end position of the door.

Leading light barriers as closing edge safety devices for gates are versatile in practical use and exemplary in the EP 0284066 and EP 1760237 . DE 8790065.3 . DE 103 02 812 B4 described.

The known Schließkantensicherungen with leading photocells have a complex mechanical retraction or folding mechanism. Since the light beam must run centrally under the door leaf, must the closing edge safety devices in the end run of the door closing movement protected against destruction. this happens by means of various mechanical Abklappsysteme or retraction in the door leaf by means of stamp. This requires a lot of effort on mechanical adjustments to the door construction. An afterthought Installation in existing gates is only disproportionate with one high effort possible.

The The object of the invention was to develop a leading optical closing edge safety device, which is connected to the various Door constructions without constructive additional expenses for new goals, but also to existing gates can be installed and an integrated Has casserole stopper function.

The Solution according to the invention was considered the already widely used photoelectric sensors in leading optical Schließkantensicherungen with the known disadvantages found by the optical safety edge safety off two housings - one outer Housing and an inner housing - consists and the inner housing with the light barrier by means of a Pen and a guide in the open state of the gate up to a predetermined distance from the outside Housing is moved out and thus the function of Leading closing edge safety device met. In the end position of the door becomes the inner housing with the light barrier retracted into the outer housing and switches so that the light barrier off.

The outer Housing of the closing edge safety device has as Part of the basic housing a casserole stopper and keeps the door leaf at a defined distance to the ground and thus the required distance for the rubber seal of the door leaf to the ground. An otherwise required casserole stopper eliminated.

The above-described solution according to the invention is due to additional light barriers in the inner housing the leading closing edge safety device as parallel light barriers with wide door leaves z. B. in cold storage or as mutually arranged light barriers in industrial doors, where forklifts operate, expandable to these applications.

In the 1 the leading optical safety edge safety device is shown. The outer housing with integrated casserole stopper ( 1 ) with the cap nut ( 2 ) and the fixing screw ( 3 ) attached to the existing door profile for easy installation. The inner housing ( 4 ) with the light barrier ( 5 ) is movable in the outer housing ( 1 ) and by means of the spring ( 6 ) extended in the leading state. When closing the door system, the inner housing ( 4 ) in the outer housing ( 1 ). The sensors transmitter ( 7 ) and receiver ( 8th ) are now switched off and protected against contamination, while the integrated in the outer housing casserole stops ( 9 ) the door leaf at a defined distance to the ground.

• • in ihrer breiten Anwendung für neue und vorhandene Toranlagen sowie in einer kostengünstigen Herstellung und einem zuverlässigem Betrieb;
• • in ihrer einfachen Montage;
