  • Patent number: 8305685
    Abstract: A loupe support system includes a frame (12) which can be mounted at the head of a user and at which a holding device (18) is mounted, an elongated support element (30, 31, 68) which, at its central region, is supported at the holding device (18) such that it can rotate about its longitudinal central axis, wherein a respective loupe ocular (34) is mounted at the support element (30, 31, 68) on each of both sides of the holding device, and a light mounting element (22) supported at the holding device (18) such that it can rotate about a rotary axis being coaxial with respect to the longitudinal central axis of the support element (30, 31, 68).

  • Patent number: 7871174
    Abstract: A head band for diagnostic instruments comprising a light source and a battery has, at its back support part (12), a flat housing (21) for adjusting and fixing the head band length by means of a rotary knob (22). An accumulator module (31) optimized with regard to volume, weight and weight distribution can be mounted and detached by means of bayonet-type grooves (25) at the housing (21) and pins (33) at the accumulator module (31), and can be fixed by means of a resilient spring (26) at the housing (21) and a recess (34) in the accumulator module (31) without impairing the function of the rotary knob (22).

  • Patent number: 7507927
    Abstract: A battery grip for diagnostic units comprises a grip sleeve for accommodating batteries, at the upper end of which a metal sleeve for accommodating a consumer load, such as an electric bulb, is mounted, a guide opening formed in the wall of the grip sleeve, a switching slide being guided the guide opening in a longitudinal direction of the grip sleeve, a contact member extending from a lower end of the grip sleeve with one contact end into the guide opening, and a contact spring member having one end conductively connected to the metal sleeve manner and another free end extending into the guide opening such that the free end is disposed above the contact member and is brought into contact with the contact member by displacing the switching slide. The contact between free end of the contact spring member and the contact member is created by at least two contact points. At least one longitudinal recess is provided in the contact end of the contact member.
