Abstract: A ventilation system for sectional-type garage doors, utilizing rollers and axle pins with device bodies of adjustable geometry to hold the upper section of the sectional door at an inwardly-rotated angle to facilitate venting of the space. Component installation and operation does not impact normal operation and is completely reversible, requiring no modifications to the door itself.

Abstract: A protection device for the protection of people against moving rail vehicle in a railway station area comprises an inner and an outer protective wall (11, 12, 76, 77, 88, 89). The station area contains a platform (4) whereby the platform (4) contains a platform edge (2, 22). A first side of the platform edge (2, 22) has tracks and a second side of the platform edge (2, 22) has a platform plateau (23). The platform plateau (23) is designed as a waiting area for people. The protective wall (11, 12, 76, 77, 88, 89) is directly adjacent or near to the platform edge (2, 22) and between a retracted state and an extended state adjustable in such a way that in the extended state (11, 12, 76, 77, 88, 89) access to the tracks is obstructed, in the retracted state access to the tracks is free.

Abstract: A panel body (11) includes: a panel-like base material (12); a groove (25) which is continuous along at least a part of an outer circumferential end portion of the base material (12), and is recessed to the inside of the base material (12); a soft material (13) which is provided on one or more surface of the base material (12); a cover material (14) which covers the base material (12) and the soft material (13), and in which the outer circumferential end portion is caught in the groove (25) in the outer circumferential edge portion of the base material (12); and a fixing member (30) which fixes the cover material (14) in the groove (25).
