The invention relates to a system consisting of carbon brushed and circular pot-like carriers (10) having at least one electrical interconnection and surrounding a commutator of a motor, and a frame (18) that projects peripherally over the carrier and can be fixed into position between a motor housing and a transmission housing, proceeding from the peripheral surface of the carrier. In order to attain a simplification in the manufacture of carriers for different applications, it is proposed that...

The invention relates to a bicycle and like, having a rear wheel (22) or flywheel, and provided with a pedal group comprising a central shaft and a gear wheel (5) integrally coupled each other, a left crank (1) and a right crank (1), coupled on the two ends of the central shaft, characterised in that a pedal crank (7) is rotatably coupled with each one of said left and right cranks (1) by mechanical means (6, 8, 10) creating a freewheel like mechanism between the crank (1) and the corresponding ...

A sailboard for sailing in water includes an elongated hull defining fore and aft and having a top and a bottom, and a panel integrally connected to the bottom of the hull near the aft end and extending beyond the aft end. The panel is relatively rigid at its distal end. An apparatus is connected to both the hull and the panel, and is operable for moving the distal end of the panel from a first position to a second position. The hull and the panel defining a relatively continuous flat surface fo...

A chair or the like with an undercarriage, having a seat surface that is attached in a resilient manner to the undercarriage and a backrest that is connected in a resilient manner to the seat surface, wherein to assure a flexible and individual conformity of the chair or the like to the body placing a load on it. A plurality of flexible strips are disposed next to one another and attached in their end area in a nearly horizontal orientation to the undercarriage which act as a seat surface, and w...

A folder for receiving documents or the like is formed from a corrugated board or paper blank, which is folded for forming a front sheet and a back sheet. For the retaining of the front and back sheets insert elements are used, which are inserted with pins in the open front faces of the blank. The folder can be produced with much less effort and expenditure than known folders and can be constructed as a hanging folder or as a rubber strip folder.

There is provided an occupant-propelled land vehicle, such as a bicycle, having a frame, at least one front wheel, at least one rear wheel, and a seat for the rider of the vehicle, supported by the frame, wherein two levers, each having a front end and a back end, are pivoted on the frame on each side forwardly of the rear wheel and at a point substantially closer to the back end than to the front end. Two rigidly interconnected and spaced-apart parallel discs, one of the discs being toothed, ar...

The invention relates to a method for grouping a multitude of film-like or sheet-like materials, which are stacked in a magazine (20) and which consist of at least one material layer, using at least one suction apparatus (42), which suctions the film-like or sheet-like materials in a clocked matter while removing them from the magazine, whereby one film-like or sheet-like material at a time directly rests with a portion of its surface that forms a contact surface against the suction device. To t...

The invention relates to a device for machining band-like or plate-like material (1), especially for punching, notching and forming it, the device comprising the body (2) of the device, at least one tool holder (3), most preferably a gap frame tool holder, between the upper branch (4) and lower branch (5) of which the material (1) to be processed is arranged to be fed, and to the upper branch (4) of which tool holder (3) is connected an upper tool magazine (6) comprising a plurality of upper too...

A method forming, in a simple manner, corner joints or the like in structures, such as articles of furniture incorporating panels of chipboard. A typical corner joint is formed using a connecting member in the form of a length cut from an extrusion of constant cruciform cross-section. Adjacent edges of two panels defining the corner are secured in respective diagonally opposite channels of four V-section channels defined by the extrusion, one of the two remaining channels which faces outwardly f...
