Description

BACKGROUND OF THE INVENTION (a) Field of the Invention

  The invention relates to a flange structure for bars of different diameters, and more particularly to a flange structure which allows a flange base to be maintained on any type of bicycle handlebars, or can be used on the rear luggage rack of a bicycle for hold objects firmly.

  (b) Description of the Prior Art Technological development involves modernization of the various types of vehicles, also improving the comfort of modern people. However, at the present time, the depletion of natural resources and the deterioration of the environment have given new impetus to the bicycle. Indeed, it does not consume energy and does not pollute the environment. Moreover, the bicycle not only helps to protect the environment, but it also allows you to exercise.

  It is also an extremely convenient means of transportation for certain professions. For example, a newspaper delivery man uses his bicycle to deliver newspapers to every home, a postman uses the bicycle to deliver mail along large avenues and small streets, and a milkman uses his bicycle to dispense milk in the morning. .

  Therefore, since these individuals use the bicycle as a means of transportation, it is natural to hang a bag or basket there to place objects. However, the traditional method of securing a bag is simply to hang it on the bicycle without fixing it effectively. Therefore, it is inevitable that this produces a rocking of the bicycle resulting in instability during its use.

  In addition, the current craze for bicycles has resulted in the manufacture of bicycles with handlebars of different diameters. Therefore, a fixed base flange device can not be used with a traditional bag or basket. Moreover, if the flange device is made for a single handlebar diameter 1 and the user who makes the purchase discovers on his return home that his purchase can not be installed on his own bicycle , it is disappointed and must exchange the purchase, which is an additional disadvantage. In addition, if the manufacturer of the fixed base flange device separately manufactures and packages the devices for the large diameter bars and the small diameter bars, its manufacturing costs will be higher and it will have to increase its storage area.

  The object of the present invention is therefore to provide a flange structure that can be used on bars of different diameters.

SUMMARY OF THE INVENTION

  A first object of the present invention is to provide a flange structure for bars of different diameters facilitating the maintenance and to be fixed on the handlebars or the rear luggage rack of a bicycle.

  Another object of the present invention is to provide a flange structure for bars of different diameters that can be installed by oneself.

  This removable attachment allows flange structures to be mounted on large and small diameter bars, with auxiliary struts being arranged with the flange structures to form different sizes of openings.

  In order to achieve these objectives, the flange structure comprises upper flange pieces, lower flange pieces, a set of first struts and a set of second struts, in which attachment portions and holes are placed on the pieces. upper flange. Anchor grooves are formed on the lower flanges of the upper flange pieces. The lower flange pieces are arranged to correspond with the holes and the anchor splines. The anchoring grooves serve to fix the first spacers, the second spacers being arranged in the first spacers in order to block them.

  Fixing spaces are thus formed between the upper flange pieces and the lower flange pieces after adding the first spacers, to maintain a bar of relatively large diameter.

  The fixing spaces formed between the upper and lower flange pieces, after having added the second spacers, make it possible to maintain a bar of a relatively small diameter. A flange base securely attaches a backpack (or basket) to the handlebars of a bicycle and a lower mounting plate securely attaches a package to the rear luggage rack of a bicycle.

  In order to allow a better understanding of said objectives and the technological methods of the invention described above, the figures below are briefly presented and then described in detail to show the preferred embodiments of the invention.
