Definitions
- the invention relates to the field of workshop or site equipment. More particularly, the invention relates to a portable workbench.
- An electrical technician (or other), as part of a maintenance or repair work on site, needs to move with generally documents, a laptop and tools and equipment. It also needs on-site provisions for its effective and safe installation for the duration of the project; his installation must enable him to intervene between a few hours and several days depending on the nature of his intervention. However, an industrial production unit does not generally offer good provisions for an effective and safe installation of the service technician.
- U.S. Patent No. 5,452,908 discloses a portable wheeled workbench.
- the bench includes a frame, a hinged and foldable panel on the chassis and a small storage box for tools.
- the solution is interesting in that the workbench includes a foldable table, facilitating transport and allowing the technician to settle with his equipment, stored in the small chest.
- This workbench, once folded, is still bulky and seems poorly suited for after-sales service, maintenance in all types of environments, tertiary or industrial.
- Other folding sets are described in US 2012/217727 and US 6,182,724; these documents also illustrate the lack of robustness and ease of use / transport of known equipment.
- the object of the invention is to propose a solution for overcoming the disadvantages of the prior art, in particular of the prior art mentioned above. More particularly, the invention aims to provide a bench solution that is easily transportable without compromising its robustness, and economic construction.
- the invention relates to a portable workbench comprising: a foldable frame; and a main panel, forming a work surface, removably mounted on said frame; remarkable in that the workbench, in mounted position, has a rigid upper frame of square or rectangle shape; the panel comprising opposite first elements front and rear of said frame and the frame comprising second opposing elements of left and right of said frame, connected to said first elements; and in that said main panel comprises a first and a second rigid work plate, said first elements each comprising a first and a second sub-element fixed under said first and second work plates, respectively; said main panel further comprising pivot pins connecting the inner ends of each of said first and second sub-members, said pins being arranged so that said inner ends are contiguous in the mounted position of the workbench and are fit pivot upward to fold the panel to disassemble the workbench.
- the rigid upper frame comprises only formed of the first front and rear elements as well as second left and right elements related to said first elements front and rear.
- the rigid upper frame means able to withstand a mass deposited on the work surface and exerting a force in the direction of gravity.
- the ends of the second elements of left and right extend over less than 20% of the length of said elements which is favorable to the distribution of load forces on the frame.
- the rigid upper frame is preferably metallic.
- the rigid plates can be made of wood, for example in multiplex, with a thickness of between 5 mm and 25 mm; other suitable materials may however be used, the rigid plates may for example be sheet metal, stainless steel and rigid polymer.
- the upper rigid frame of the workbench can extend along the periphery of the panel. The contact between the inner ends of the first and second sub-elements of the front and rear of the frame allows blocking of the panel which, thus, can not pivot downward when a large load rests on the work surface.
- the main panel in the mounted position on the chassis is configured to support a maximum mass of the order of 50 kg, 70 kg or up to 100 Kg, distributed on the surface.
- the first and second sub-elements comprise inner contact edges, the inner ends of each of the first and second sub-elements being contiguous at said inner contact edges in the assembled position. the workbench.

- the pivot axes are level, in the vertical direction, the lower sides of the first and second sub-elements.
- This measure of the invention is interesting in that the lower sides of the sub-elements come into contact by pivoting in disassembled position of the frame.
- the contact edges of the first and second sub-elements of square section have chamfers on the lower horizontal portions of said section, so as to form V-shaped housing for the pivot axes.
- two rigid plates extend over more than 50% of the panel area, preferably more than 70%, more preferably 100% of the panel area; the space without rigid plate attached to the front and rear elements of the frame can be filled by a removable additional rigid plate.
- the workbench comprises coupling means which ensure the connection of each of the outer ends of the first elements to the corresponding ends of the second elements.
- the coupling means are advantageously composed of housing, for example by shoe, and clamping tab made on the first opposed elements front and rear.
- the coupling means are made by clamp or by clamping clamp.
- the coupling means are quick release means to facilitate removal of the removable panel.
- the workbench comprises means for main locking of at least one of the two pivot axes, preferably each of the two pivot axes.
- the foldable frame comprises in the mounted position of the bench, a rear frame extending vertically along the rear element of the frame and having at each of its horizontal ends a vertical pivot axis receiving a lateral frame, the second elements of the upper frame forming the upper elements of said side frames.
- the chassis as such once mounted, thus describes a U-shape which comprises only at the structural level, the vertical elements formed by the rear frame and the two side frames.
- each of the side frames is provided at its base with two steerable wheels with brake for moving the workbench.
- the portable workbench is mobile and can for example serve as a servant.

- the rear frame of the frame comprises two half-frames and a vertical central pivot axis of said half-frames, said rear frame including, preferably further, auxiliary locking means of said central axis vertical.
- the rear frame of the foldable frame comprises upper and lower horizontal elements, the vertical central axis of pivoting being formed by a vertical central rear hinge on each of said upper and lower horizontal elements.
- the vertical central pivoting axis of the rear half-frames is arranged for a pivoting of said two half-frames towards the inside of the workbench.
- the frame has a W-shape during its folding.
- the frame in folded configuration has substantially the same external dimensions (length - width) as the main panel in folded form, so that a rigid plate of work. This measure facilitates the storage of the frame and panel (x) folded, for example in a transport bag of suitable size.
- the rear half-frames and the side frames are of width between 400 mm and 1000 mm, preferably of the order of 600 to 700 mm. They may be of identical width, which reduces the bulk of the frame in the folded position.
- the height of these elements can be of the order of 700 to 1000 mm.
- first and second rigid plates of the panel are of square shape with sides of length between 400 mm and 1000 mm.
- the workbench further comprises an anti-burglar system comprising fixed flaps extending along at least one of the lateral frames and / or the rear frame, preferably along each of said side and rear frames, and sashes pivotally mounted along the vertical front members of the side frames.
- the workbench further comprises a secondary panel of the type of the main panel and intended to be mounted on the foldable frame to form a storage surface located below the work surface .
- the lateral frames comprise horizontal lower elements vis-à-vis the second upper elements, the auxiliary panel being locked to said horizontal lower elements.
- the measures of the invention are interesting in that the workbench is portable and robust. Indeed, the frame of square or rectangular shape can support a large load disposed on the panel of the workbench. The craftsman can work heavy loads. Thanks to the steerable wheels, the workbench can be easily moved to another workstation, or put into a room separate, allowing the craftsman to isolate himself to sit and do administrative tasks.
- the panel is foldable and easily removable from the frame as well as simple construction which makes it economical. A very good compactness is achieved in particular with a folding frame in W, greatly facilitating transport in a van or car.
