FR2806695A3 - RETRACTABLE STRUCTURE FOR A SCOOTER - Google Patents

Abstract

A retractable structure for a scooter comprises a retractable stem tube (3) pivoting relative to the front tube (1) and connected to a front caster (2), and a handlebar (4) connected to the upper part of the stem tube ( 3). The two ends of a side handlebar lever (4) extend so as to each form a bend portion (41) so as to hook onto the rear of the frame at an appropriate angle after the stem (3) is retracted, so as to facilitate the fact of carrying the scooter while holding its stem tube.

Description

RETRACTABLE STRUCTURE FOR A SCOOTER

  The present invention relates to a retractable structure.

  ble for a scooter, and, more particularly, a structure which retracts the stem tube connected to the handlebars and fixes the stem tube flat on the board so that users carry the scooter by the stem tube.

  In a scooter using the existing technique available

  available on the market, a caster swivels at each of the front and rear ends of the chassis, and a board is placed on the middle section of the chassis. During

  use, one foot is placed on the board and the other

  tre foot pushes against the ground to give inertia to the board in order to roll. Then, the user puts both feet on the board to move forward until the scooter decelerates until the approach of the stop. Again, the user must press with one of his feet against the ground to go forward. The scooter can be used as a means of ride,

  in addition to allowing fun or sports.

  In addition, a handlebar pivots on the front tube of the chassis and is connected to a stem tube placed on the caster.

  forward to control the direction in which we are turning.

  The handlebars and stem tube both consume a lot of space, which makes the scooter difficult to store or carry. An improvement has been made in which the handlebar and the stem tube both pivot relative to each other so that they

  are foldable. However, the scooter remains diffi-

  to wear because the handlebars and the stem tube folded

  are not fixed in place. Therefore, some ac-

  retainers, such as a fastener and tape

  are required to hold them in place.

  This causes impractical operation, and one can

lose accessories.

  The main object of the present invention is to pro-

  curing a retractable structure allowing users to

  teurs to easily carry the scooter by the tube

  stem which folded and fixed in place at the level of the sec-

  tion of the scooter. The structure has the character-

  téristiques that the two ends of the lateral lever of the handlebars are made according to a curve in order to catch

  on the rear caster of the chassis when the po-

  tence is retracted and lies flat on the board.

  Figure 1 is a schematic view showing the struc-

ture according to the present invention.

  Figure 2 is a first schematic view showing

  the retraction process according to the present invention.

  Figure 3 is a second schematic view showing

  the retraction process according to the present invention.

  Figure 4 is a third schematic view showing

  the retraction process according to the present invention.

  Figure 5 is a view showing the present invention

when it is retracted.

  As shown in Figure 1, a stem tube retracted

  ble 3 pivots relative to a front tube 1 of a chassis and is connected to a front caster 2 of a scooter. A

  handlebar 4 is connected to the upper part of the po- tube

  tence 3. At the point where the stem tube 3 is retracted,

  a curved extension joint (see also fig.

  gure 2) is arranged in connection with a device for

  quick connection 5 used to connect the stem tube 3 and the front tube 1 in order to achieve the goal of folding and fixing the stem tube 3 in place. The two ends of the lateral lever of the handlebar 4 are each produced in the form of a curved part 41. The curved part 41 and the handlebar 4 form a C shape with the opening looking towards the front of the scooter, so to facilitate turns under the control of

  handlebar 4 which is connected to the front caster 2.

  When the scooter is not used and the stem tube 3 is retracted so as to lie flat on the board, the curved part 41 is used to make a hooking on the rear of the chassis for a

easy handling and storage.

  If we refer to figure 2, first of all, the dis-

  positive quick disconnect 5 located where the

  stem tube is retracted is released for use

  sator pulls the curved joint 6. Then, as it-

  glossy in FIG. 3, the stem tube 3 and the handlebar 4

  connected to the front caster 2 turn to tilt.

  The curved joint 6 is used to retract the stem tube 3 downwards to such an extent that each curved part 41 is in an inclined position

  compared to a rear caster 7 of the chassis, as it-

glossy in Figure 4.

  Finally, the stem tube 3 is laid flat on

  the chassis, with the curved part 41 at the lower end

  handlebar 4 which is hooked on the rear caster

  rière 7 of the chassis. Therefore, the stem tube 3

  takes the form of a portable handle so that the user

  he carries the scooter holding the stem tube 3.

  The present invention, by providing a configuration

  innovative, practical and improved, allows the trotti-

  net can be retracted and fixed in place, and eliminates

  the need for an accessory to allow the use

  to wear it easily when the scooter is not

  not used or is ready for storage.

Claims (1)

CLAIM   Retractable structure for a scooter, characteristic   sée in that it comprises a retractable stem tube (3) pivoting relative to a front tube (1) of the chassis and connected to a front wheel (2) of the scooter, and a handlebar (4) connected to the part upper of the stem tube (3), and in that the two ends of a lateral handlebar lever (4) extend so as to each form a curve part (41) so as to hang on the rear of the chassis at an appropriate angle once the stem tube (3) is retracted, to facilitate the fact   to carry the scooter while holding its stem tube.
