Abstract: The invention relates to a spectacle case for keeping and protecting the glasses and their lenses against pressure and abrasion. The spectacle case is made of a material body (1) with a front side (a) and a rectangular rear side (b) separated by means of an elastic rectangular central surface (c) and folding one towards the other one following folding lines (d) and (e) and the rear side (b) being provided on the outer edge side with a notch (f) curved towards the inside of the spectacle case and which is intended to come into contact with the nose pads of the bridge, thus fixing the spectacle case on the glasses, and the glasses' temples are folding on the outside of the spectacle case.

Abstract: The present invention refers to a personal flight apparatus with vertical take-off and landing characterized in that it is a biplane apparatus constituted by two distinct parts articulated there between, the first distinct part consisting of the cockpit 1, which is hinged to the second part of the latter, which is formed of the wings assembly 6, the cockpit 1 being attached to the wings assembly 6 by two hinges 3 fixed in the upright central vertical supports 7 of the wings, and in this way the cockpit having a limited swing possibility inside of the wings support structure which in turn they are provided with four propellers 9, of ducted type and driven by electric engines 20 disposed two on the top wing and two on the bottom wing, thus forming a kind of quadcopter, the duct 10 of each propeller being provided on the inlet lip with an annular ejection slit 11, and the electrical energy required to operate the apparatus is provided by the batteries 14 placed under the pilot's seat which through the speed regu

Abstract: The invention relates to an aircraft with vertical takeoff and landing and its operation method.

Abstract: The invention relates to a spectacle case for the storage and protection of spectacles and lenses against pressure and abrasion. The spectacle case has a body, which may be constructed of either a flexible material, such as natural or synthetic leather, paper, textiles, plastic, or of a rigid material, such as metal or plastic. The body has generally rectangular front and rear faces with rounded corners, the faces being separated by a central rectangular area with fold lines; the rear face is provided with a central trapezoidal-shaped recess having a median opening. The front and rear faces are folded towards one another, to create the spectacle case, along the fold lines.

Abstract: The invention relates to an attachable spectacle case for spectacles or sun glasses capable of protecting the glasses and their lenses against pressure and abrasion. The spectacle case is made of a body (1) from a material which may be a flexible or rigid material and having a rectangular front side (a) and a rectangular rear side (b) separated by means of a central rectangular surface (c) and having folding lines (d) and (e) and the front side (a) is provided with a trapezoidal prism (2) symmetrically disposed at the bottom which is intended to secure the nasal saddle of the glasses, the spectacle case having the components of the closing device arranged on the trapezoidal prism (2) and on the rear side (b) of the spectacle case, and the glasses' temples are folded outwards of the spectacle case.
