Description

The invention relates to a mobile toolbox usable for

  work at height. Such a toolbox constitutes a rapid intervention station for this kind

of works.

  It is known to produce tool boxes or "workshop maids" which include a certain number of

  slots for tool storage and access storage

  evenings such as fixing or connection systems, small electrical equipment, etc. It is customary to create tool boxes as compact as possible to reduce their size and to lighten them as much as

do it possible.

  When it is necessary to carry out work at height, it sometimes happens that a user climbs on his tool box which, if it is not provided for this purpose, can prove to be unstable

  hence a risk of fall and injury to the user.

  With known tool boxes and when work at a height greater than 2 meters must be carried out, it is necessary to use a ladder or a stepladder which must be transported to the place of the intervention to be carried out, such a ladder or such a stepladder proving in

  bulky and sometimes difficult to transport.

  It is to these drawbacks that the invention more particularly intends to remedy by taking the opposite view from the habits of the technical field considered and by providing a toolbox making it possible to envisage interventions at height.

without risk of injury.

  In this spirit, the invention relates to a tool box comprising tool storage volumes and / or accessory storage volumes, which further comprises: - a chassis resting on several wheels, at least one of which is powered , On the ground; - a platform capable of receiving a user and

  - means of elevation of this platform au-

above this chassis.

  The toolbox of the invention effectively fulfills the function of tool storage and accessory storage thanks to its volumes dedicated for this purpose and allows a user to work at height by raising the platform above the frame. The platform being provided for this purpose, the risks of falling or tilting of the structure are minimal while the user must move, store and lock only one object, namely his tool box,

  place of a known toolbox and ladder.

  According to advantageous but non-mandatory aspects of the invention, the box incorporates one or more of the following characteristics: - The storage and / or storage volumes are formed in two sets defining between them a space for receiving the platform. Thus, the toolbox has, in the lowered configuration of the platform, a

  compact shape. In this case, the lifting means include

  advantageously at least one cylinder whose basic element

  is supported on the chassis in the aforementioned reception space.

  One can, moreover, provide that the jack crosses, in at least certain positions of the platform relative to the

  chassis, the floor of this platform.

  - The platform is provided with partitions or guardrails extending, in the low position of the platform,

  to the top of the receiving and / or storage volumes.

  These partitions or guardrails prevent an accidental fall of the user. - The platform is equipped with at least one temporary storage bin for tools and / or accessories, this bin being

  accessible by a user on the platform.

  This or these trays allow a user to work at height while having at his disposal the various materials which he needs. These tanks are advantageously provided in the upper part of the aforementioned partitions or guardrails. We can, moreover, provide that at least one of these tanks is articulated between a position of use, where it extends generally along a plane parallel to the ground surface on which the body rests, and a folded position , o it does not project towards the outside of the platform with respect to the partition or railing which it adjoins. In the position of use, the bin can be placed above the storage and / or storage volumes, while, in the folded position, it does not

  not extend above these volumes.

  - The platform is provided with at least one access door capable of pivoting in one direction, around a generally vertical axis, from its closed position. This aspect of the invention allows the user to enter the

  platform by pushing the door towards the inside of the platform

  forms while the door is not likely to open outwards in case the user comes to lean

  unfortunately on it in use.

  The invention will be better understood and other advantages thereof will appear more clearly in the light of the

  description which follows of an embodiment of a

  tool box in accordance with its principle, given solely by way of example and made with reference to the accompanying drawings in which: - Figure 1 is a perspective representation of a tool box according to the invention; - Figure 2 is a side view of the body in the position of Figure 1; - Figure 3 is a view similar to Figure 2 and on a smaller scale while the platform of the box is in the high position; - Figure 4 is a view from the front of the box in the position of Figure 3; - Figure 5 is a rear view of the box in the position of Figure 3; - Figure 6 is a view similar to Figure 2

  in another configuration of use of the body.

  The toolbox 1 shown in the figures comprises a chassis 2 resting on the surface S of the ground by means of four wheels 3 including two front drive wheels 3a and two rear steered wheels 3b. The frame 2 comprises a base 21 and two assemblies 22 and 23 extending from the base 21

  respectively above the front wheel set 3a and above

  above the rear wheel set 3b.

  In the set 22 are provided shelves 24 representing

  tees only in Figure 4 and for receiving tools such as keys, screwdrivers or power tools or pneumatic. The internal volume of the assembly 22 is isolated from the outside by two doors 25 articulated around generally vertical axes when the body 1 rests on a horizontal surface S. Under the assembly 22 is defined a box 26 in which is received a motor (not shown) for driving the wheels 3a as well as one or more batteries supplying this

  engine, also not shown.

  The assembly 23 comprises four drawers 27 in which can be stored materials and / or accessories such as dowels, collars, fittings, etc. The assembly 23 also includes shelves 24 ′, shown only in FIG. 5 and isolated from the outside by a 25 'door. 24 'shelves allow tools to be stored and / or stored

accessories.

  Above the assembly 23, a receiver 28 is formed for relatively important objects which cannot

  be housed in sets 22 and 23.

  Under the assembly 23 and inside a box 29, is

  arranged the steering system of the wheels 3b.

  A space E is defined between the assemblies 22 and 23 and above the base 21, this space being of dimensions sufficient to receive a platform 5 on which can

stand a user.

  This platform is accessible through two doors

  51 and 52 articulated around globally vertical hinges

  when the nacelle rests on a horizontal surface S and capable of pivoting only towards the inside of the

  nacelle 5, as represented by the arrows F1 in FIG. 1.

  Thus, for a user to be able to exit the nacelle 5, he must pull on the doors 51 and 52. The risks of a user falling through the doors 51 and 52 are therefore minimized. The platform 5 also comprises two partitions 53 and 54 extending, from the floor 55 of the platform 5, over a height hl making it possible to avoid a tilting of a user. The height h1 is, for example, between 90 cm and 1.20 m, preferably of the order of 1.10 m. A partition 56 connects the partitions 53 and 54 and has substantially the

same height.

  A cylinder 6 is disposed between the platform 5 and the base 21 of the chassis 2. The base element 61 of the cylinder 6 is fixed to the chassis 2 inside the space E. The upper element or element end 62 of the actuator 6 passes through the floor 55 in the configuration of FIGS. 1 and 2 and extends above the doors and the partitions. In practice, element 62 has a

height h2 of the order of 2 m.

  When work at height must be considered, a user need only take from one of the assemblies 22 and 23 the tools and accessories he needs and climb into the platform 5 before activating the jack 6 in order to raise this platform in height and work in

  satisfactory conditions of accessibility and security.

  A control module for the operation of the body 1 is provided inside the platform 5, which allows a user to control the height of the platform 5 and

  moving the chassis 2 from its working position.

  The platform 5 is equipped with two tanks 57 and 58 extending in the upper part of the partitions 53 and 54 and over their entire width. A user can deposit in these bins

  tools and accessories he knows he will need.

  These tanks 57 and 58 are accessible from outside the platform, in particular when the user opens the doors 25 or 25 'or the drawers 27. After having selected the materials he needs, the user simply places these materials in one of the bins 57 or 58. These bins are also accessible from inside the platform 5, which allows the user to easily access the materials

when working at height.

  As can be seen more particularly from FIG. 6, the container 58 is articulated around a hinge 59 with a generally horizontal axis when the body 1 rests on a horizontal surface S. The container 58 is thus movable between the position of FIG. 2 and that of FIG. 6. In the position of FIG. 2, the container 58 can be used to receive material. In this case, it extends above the assembly 23, just as the container 57 extends above

the set 22.

  When bulky equipment M must be placed on the receiver 28, the tray 58 is brought into the position of FIG. 6 where it does not interfere with the accessibility to the receiver which can

  accommodate a material M of relatively large height.

  The tilting movement of the bin 58 between the position of FIG. 2 and that of FIG. 6 is represented by the arrow

F2 in this figure.

  The cylinder 6 used can be of any known type. he can

  in particular be a hydraulic or pneumatic cylinder.

  The fact that the jack 6 crosses the floor in the configuration of FIGS. 1 to 4 and 6 makes it possible to limit the size of the body 1 whose height h3 relative to the ground is, for the most part, of the order of 1 , 10 m to 1.20 m, while the height h'2 of the jack 6 relative to the ground is only to be taken into account at the center of the body 1, this height

  h'2 being of the same order of magnitude as the height h2.

  The fact that the partitions 53 and 54 extend, in the low position of the platform 5, above the assemblies 22 and 23 allows a particularly suitable positioning of the tanks 57

and 58.
