DESCRIPTION

I 2674470

  The present invention relates to a trolley workshop for DIY

home.

  One of the main difficulties for manual workers in the home is to intervene in many cases on non-movable elements Two solutions are available to them: the on-site supply of all necessary tools, the realization at the fixed workbench, generally distant, of

  subsets necessary for the construction in progress.

  In the first case, in addition to the many back and forth for startup and storage, the handyman will work in unsuitable conditions Ground tools, use of extension cord, poor lighting, etc. In the second case, many goes and come will also be necessary to test on site the adaptation of the subassemblies, however it will also not escape some work on the site such as sanding, fitting, fixing, etc t The market provides a a multitude of toolboxes, extension cords, fixed workbenches, vices, but nothing that achieves a seductive synthesis of storage, moving or car transport functions, combined with a quick implementation of tools and an ergonomic work on the site. The various French and foreign patents that have been filed in this field generally mention incomplete devices without a general electrical connection: French patent 75 34 746 / 2,330,508 A from 1976 French patent 1,546,743 from 1968 absence of multiple electrical connections Patent French Patent 75 34 746 / 2,330,508 from 1976 French Patent 1,546,743 from 1968 US / FRG Patent 1,901,790 from 1930/1931 No Lighting Projector: French Patent 1,546,743 from 1968 US / FRG Patent 1,901,790 1930/1931 quasi absence of laying surface: French patent 75 34 746 / 2,330,508 from 1976 French patent 1,546,743 from 1968 US patent 2,646,329 from 1953 US / FRG patent 1,901,790 from 1930/1931 2 - absence of clamping jaws French patent 1,546,743 from 1968 US patent 2,646,329 from 1953 absence of moving trays: French patent 75 34,746 / 2,330,508 from 1976 French patent 1,546,743 from 1968 US patent 2,646,329 from 1953 US patent / Germany 1 901 790 of 1930/1931 absence of market 1 o French patent 75 34 746/2 330 508 of 1976 French patent 1 546 743 of 1968 US patent 2 646 329 of 1953 and are mainly oriented by their size and weight to

professional applications.

  The device which is the subject of the present invention provides a solution

  attractive to the needs of homeworkers.

  Characterized first by a toolbox mounted on wheels, it moves easily in the apartment or loads

  in most average cars.

  Only one general connection is made thanks to a cable

unrollable 10 meters long.

  In the first compartment for storing the various machines, a series of female electrical outlets with winder

  integrated and cable guide as a brake is available.

  The handyman can easily unroll the cable needed to

  his work This self-locking in the desired position.

  When storing in the compartment, the cable wraps itself. Each machine is permanently connected, the user can

  choose at any time the desired machine, ready for use.

  The automatic take-up sockets allow you to normally disconnect the power cord of each machine for possible individual use. The front and side walls open in two panels, each horizontally giving off a large laying surface for

tools, parts or screws.

  In addition, two small panels moving in rotation along a vertical axis allow to keep at hand the small

  tools or fixings immediately usable.

  The front panel is equipped with clamping jaws with a large radius of curvature and differential thickness compensation in the horizontal plane thanks to a double articulation.

  tightening takes place by cranks and screws.

  When machining a piece pinched in the jaws, the front panel at the bottom has fold-down legs providing the step necessary for the immobilization of the bench An adjustable support foot holds in position

  machining parts of great length.

  The top cover is locked in the open position by a compass It has regularly spaced holes and adjustable cleats to arrange the tools as needed

  straps help immobilize them during transport.

  A projector secured to the lid is adjustable in all

directions.

  Figure 1 shows the device in working position.

  Figure 2 shows it in the closed position.

  Figure 5 shows the detail of the clamping jaws.

  FIG. 6 is an exploded perspective view of the female sockets

integrated winder.

  Figure 7 is a sectional view of the integrated retractor socket.

  Figure 8 taken female in top view.

  Figure 9 female socket on the left side.

  Figure 10 female socket right side.

  With reference to these drawings, the device comprises a metal structure of light alloy FIG 2 which can also be made of steel angles The walls (5), (6) and (9) are plywood 8 mm, the wheels (1) in synthetic material have a diameter of 200 mm, and the mains cable (2) rollable on the face

back measuring 10 meters.

  The electrical sockets (3) are made of two injected plastic shells FIG. 6 The sockets (14) and (15) fit into the housings and the grooves provided for this purpose (16), a plate (17) holds the conductor (15) away from the conductor (14) and at the bottom of its housing in the half shell (19) The mounting of the two half shells (18) and (19) is by snapping lugs (20) in the holes (21) and lock

  by the cylinders (22) and (23) on the half-axes (24).

  4 - The cylinder (22) has two brass conductive tracks (25)

  each connected to a tongue (26).

  The tabs through the hole (27) on the other side of the axis (24) make electrical contact by pinching in the conductors (14) and (15). Tongues (28) fig 9 ensure the rotating contact on the cylinder (22) and an electrical connection is made domino (29) for external connection A spiral spring (30) fig; 7 and 10, whose ends are inserted in housings (31) and (32) provided for this purpose ensures the rotational drive of

the cylindrical socket (3).

  A cable guide brake (4) articulated in (33) ensures by its own

  braking weight of the cylinder via the shoe (34).

  The pull of the cable (35) Fig 9 initially connected in (36)

  Fig 7 and 8 loosens the brake and allows the unwinding of the cable.

  The removal of the tension releases the brake (4) which self locks the reel (3) A light restraint on the cable

allows automatic winding.

  The side walls (6) and front (5) Fig 1 open articulated

  by piano hinges and chain retainer.

  The feet of the step (5) fig 1 are foldable when the

wall is closed, fig 2.

  The clamping jaws (37) (38) fig 5 of the vice (7) fig 1 are in high strength plywood The movable jaw (37) is articulated along two axes one horizontal (39), the other vertical ( 40) The tightening is obtained by crank (41), screw (42) and nut (43) articulated on a horizontal axis, a fitting (44) ensures the articulation of the jaw (37) and the positioning of

the crank (41).

  A stabilizing bar (45), detachable if necessary,

  provides lateral guidance of the movable jaw (37).

  Two movable trays (8) fig 1 located on either side of the fixed jaw articulated along a vertical axis are totally

retractable during storage.

  The upper cover (9) fig 1 articulated by a piano hinge opens in a vertical position, it supports a directional lighting (10) This projector in the folded position is fixed by the straps (13) holes (46) regularly spaced are intended to receive installable cleats on demand The straps 13

  immobilize tools during transport -

  A main switch (12) is installed on the front left.

  A handle (11) fig 1 and fig 5 allows easy movement of the assembly. A support (47) adjustable in height with three folding feet is

  usable for the machining of long pieces.

  The device which is the subject of the present invention may be made either from a structure of square-section aluminum tubes such as the first prototype or from angles.

welded steel.

  The partitions, shelves are plywood but could be

  also made of honeycomb synthetic material.

  The jaws are made of plywood.

  Cable reels are made of injected plastic.

  Specific versions, specially designed for particular work: painting, electricity, plumbing can be made knowing that the basic version remains universal.
