Abstract: Spectacle having two temples which are each articulated via a pivot connection to an optical central section which covers the field of vision in the position of use and can be pivoted from a storage state, in which the temples are applied to the optical central section, to an operating state, in which the temples are folded out from the central section, the optical central section being manufactured from a flexurally elastic material. The two temples are each articulated to the central section via a curved pivot axis of the pivot connection or via at least two linear pivot axes of the pivot connection arranged transversely to one another. In this way, glasses can be produced in which, in the position of use, light entering laterally, which does not cross the optical central section but nevertheless reaches the eye of the wearer, is largely suppressed.

Abstract: A portable device for the optical signal transmission from and to the human eye, in which it is proposed that a rod-shaped housing (1) is provided, on the two end regions of which at least one emitter (3) and/or detector of electromagnetic waves is arranged and which has a holding clamp (2) in its middle region, wherein a power supply for the respective at least one emitter (3) and/or detector as well as a control unit (8), which is connected to the at least one emitter (3) and/or detector, are provided within the rod-shaped housing. The invention provides a portable device for the optical signal transmission from and to the human eye, which can be worn with a high wearing comfort in a discreet manner in the vicinity of the head and, and in particular allows the device to be worn in parallel with commercially available spectacles. Furthermore, the handling, storage and transport of corresponding devices are greatly facilitated.

Abstract: A portable cooling device with a wristband (17) and a cooler arranged on the wristband (17), in which the cooler is designed as an air flow generator (1) for an airflow directed in an exhaust direction of the cooler (1), wherein the airflow generator (1) is arranged in a holder (11) which is fastened or formed to the wristband (17) and which at least has a extension (10) protruding in the exhaust direction, said extension (10) at least located sectionally within the airflow or enclosing the airflow at least sectionally. The invention thus provides a portable cooling device which can be designed to be extremely small and compact and can thus be worn inconspicuously. The device according to the invention is also robust and has a lower power consumption compared to conventional devices.

Abstract: A protective helmet with a helmet shell (3) which, when it is in use, at least partly encloses the user's head with the exception of the face area, a chin guard (1) which, when it is in use, encloses the lower parts of the user's face area, as well as a visor (4) preferably arranged in a pivoting manner on the helmet shell (3) for covering the visual field opening between helmet shell (3) and chin guard (1), with the chin guard (1) comprising two sections (1a, 1b) which are movable relative to each other. It is provided in accordance with the invention that each of the two chin guard sections (1a, 1b) is pivotally arranged on the helmet shell (3), and said pivoting arrangement of the chin guard sections (1a, 1b) on the helmet shell (3) takes place every time by means of a flexible plate element (2) which connects the helmet shell (3) to the corresponding chin guard section (1a, 1b).
