Abstract

two-seater Bicycle with front and rear wheel (9) and with a front and rear a rear pedal crank unit (2, 2 ') each with associated Sprocket sets (3, 3 ') leading to a chain drive of the rear wheel (9) belong, wherein the pedal crank units (2, 2 ') are coupled together or are connected, and the bicycle frame (4) a height-adjustable double seat (5) is attached, and that only front of the movable fork (18) or Steering device (19) a handlebar (7) with retaining grips (17) grown characterized in that the pedal crank units (2, 2 ') coupled on each side at the end of the crank by a double entry bar (1) are.

Description

  • The The invention relates to a two-seat bicycle with the generic term of the claim 1 specified characteristics.
  • Such a bicycle is from the patent US 3,191,965 known. This has a double seat and a handlebar from on. But it is equipped with two pedals on each side.
  • In addition, for example, from the FR 823 760 Two-seater bicycles, speak tandems known. These bicycles usually have two saddles, two handlebars and two pedals on each side that are coupled, as well as in the GB 480,376 described, or even in a non-coupled manner to ensure the classic drive. It can not always be avoided when starting the pedals slipping, which is often associated with pain. This is often the case with children and handicapped people.
  • adversely is in these tandems also the considerable length, the at the shutdown and underlines the awkwardness of these vehicles during transport. Even curves can not so easy to be driven There is also no immediate Contact the co-driver, as the frame construction and the mounted on it two handlebars and two separate saddles prevent this.
  • Of the The invention defined in claim 1 is based on the problem avoid the aforementioned disadvantages of the two-seater bicycles.
  • This Problem is solved by the features listed in claim 1 solved.
  • The particular advantages of the invention are that the double tricks on each side of the bike, unlike at usual Pedals are to be operated even with eyes closed. This excludes injuries by slipping off the feet and allows that the double tricks are even barefoot to operate.
  • The Double tricks guarantee a joint-saving and simple Occurs movement. The circular motion, with the coupled double triplets achieved, gives an optimal power transmission via a chain on the rear wheel from.
  • The Two-seater bike can easily be driven in solo mode become. It acts outward rather normal and self-evident, What a typical tandem because of its separate non-binding Bicycle half and its length not the case.
  • The padded and height-adjustable Double seat possible the riders a better contact by holding or clasping the front person, similar like driving a motorcycle. A relaxed, soulful and comfortable driving pleasure of two People is guaranteed.
  • The if necessary, the person traveling along may also use a holding strap hold on to enjoy the ride safely. The one handlebar that only mounted on the front of the steering device, emphasizes the solid and sporty, and walks away from the typical tandem appearance. By the compact design is this two-person bike, which is not essential longer is as a solo bike (usual design), extremely handy and leaves Transport well in bus, train and car.
  • A advantageous embodiment of the invention is in claim 2 specified. The development according to claim 2 makes it possible that the Doppeltrittleisten also at other known multi-seat bicycles, where the pedaling takes place synchronously, can be grown.
  • Further advantageous developments of the invention are the remaining dependent claims remove.
  • embodiments The invention are illustrated in the drawings and will be explained in more detail.
  • It demonstrate:
  • 1 the two-seat bike in a ready-to-drive state,
  • 2 a top view of the bicycle with the Doppeltrittleisten,
  • 3 the attachment of the double tricks on the two pedals of one side.
  • It follows the explanation the invention with reference to the drawing according to the structure and the mode of action.
  • The two-seat bike is a very compact bike in its construction. At the in the frame ( 4 ) mounted two crankshafts ( 11 . 11 ' ) are each a crankset ( 3 . 3 ' ) attached. The pedal crank units ( 2 . 2 ' ) are on each side at the same end of the crank by a double entry 1 ) connected. The double tricks ( 1 ) are with safety edges ( 16 ), whose height is chosen individually, so that a forward and slipping of the feet is avoided, such as 2 shows. The frame ( 4 ) is designed so that the two pedal crankshafts ( 11 . 11 ' ) either at the same level or the front pedal axle ( 11 ) are provided deeper, so that the Doppeltrittleisten ( 1 ) are arranged either horizontally or that the double tricks ( 1 ) are slightly inclined forward, such as 1 shows.
  • The attachment of the double tricks ( 1 ) on the pedal crank units ( 2 . 2 ' ) takes place either on the two pedals ( 13 . 13 ' ) per side with mounting clamps ( 14 . 14 ' ), as 3 shows, or other fasteners that allow a screw. Or every double entry bar ( 1 ) is supported by two built-in bearings ( 6 . 6 ' ) attached to it, like 1 shows.
  • By synchronous pedaling, the power transmission from the double-deck and the cranksets ( 3 . 3 ' ) by means of chain ( 12 ) and a guide sprocket ( 10 ) on the rear wheel ( 9 ) transfer.
  • On the frame ( 4 ) is a padded, height-adjustable double seat ( 5 ), with the pull-out seatposts ( 15 . 15 ' ) may also be designed resilient.
  • The frame ( 4 ) in total can be performed folding or folding, as well as provided with a suspension.
  • A luggage transport device can be attached to both the rear fork and the front fork ( 18 ) to be assembled.
  • For the two-seat bike is only a handlebar ( 7 ) with retaining handles ( 17 ) provided at the front of the movable fork ( 18 ) or steering device ( 19 ) is grown.
  • Of the Drive can also be assisted by a front hub or rear hub electric motor
  • The Two-seat bike can also be produced as a tricycle.
  • All illustrated and described features and their combination are essential to the invention.
