  SERVING STORAGE AND CLASSIFICATION OF WORKING ACCESSORIES A

  SYMMETRICALLY DISTRIBUTED MOBILE STORAGE MEDIA.

  The invention relates to a dessert for storing and classifying work accessories - in particular tools - comprising a chassis, a plurality of storage supports associated with the chassis at different heights one above the other, certain of these supports. storage being associated with the chassis in a mobile manner so that it can either be retracted inside the chassis and thus limit the external dimensions of the trolley, or deployed outwards in order to make the accessories accessible. We already know many types of trolleys, generally mounted on casters to be able to be mobile, and which make it possible to store, classify, or simply to have various accessories on hand. In particular, there are known serving trolleys for domestic use serving and serving dishes or dishes. However, such services do not allow the transport, storage and classification of heavy and more specific objects such as tools, or laboratory accessories. There are also known mobile trolleys used in the mechanical field or in workshops for arranging and transporting hand tools or tools for machining machines. However, the known trolleys used in mechanics either have a prohibitive size to provide easy integration into a workshop, or do not provide sufficient storage space. In addition, when there are mobile storage supports such as drawers or extendable trays, these tend to considerably unbalance the service when they are in the deployed position. The invention therefore aims to remedy the aforementioned drawbacks of known trolleys, and relates to a trolley offering a larger storage area than the trolleys of the prior art, having the smallest possible footprint when it is not used or on the move, so as not to hinder the maneuvers and movements of people moving around,

26 18 3 65 2

  providing immediate accessibility to the accessories that it supports, and whose balance is always perfectly preserved, even when said accessories are heavy objects such as hand tools or for machine tools. Another object of the invention is to provide such a service which is more secure in use than the services of the prior art. Yet another object of the invention is to provide such a service whose cost price is as low as possible. To this end, the invention provides a service of the type mentioned above, characterized in that it comprises, for each level of mobile storage support, a plurality of such supports distributed regularly at the same height symmetrically around the service, and in that the supports of the same level are associated with the chassis so that their path of movement and retraction are symmetrical around the service, the supports being always, even in the deployed position, symmetrically distributed around the service . According to the invention, the supports of the same level are mechanically associated with each other by association means permanently imposing a symmetrical configuration of these supports around the service, a movement of retraction or deployment given to the 'one of the mobile supports automatically generating a movement of retraction or deployment of other mobile supports of the same level in the same proportions and symmetrically with respect to the service. The supports of the same level are regularly distributed around a theoretical vertical passing through the lift center of the service and the deployment and retraction paths of these supports are symmetrical

  around this theoretical vertical.

  Other characteristics and advantages of the invention

  will appear on reading the following description which

  refers to the single appended figure representing a perspective view of a trolley according to an embodiment

preferential of the invention.

  The invention relates to a storage and filing cabinet 1

2618 365 3

  of working accessories - including tools -. The preferred embodiment shown and described is more particularly suitable for arrangement, classification and transport of tools for machining machines in a workshop and in the immediate vicinity of the workplace. It therefore allows the user to have his tools at hand at all times

near the machine.

  The trolley 1 according to the invention comprises a chassis 2, and a plurality of storage supports 3 associated with the chassis 2 at different heights one above the other - some 3b of these storage supports 3 being associated with the chassis 2 in a mobile manner to be able to be either retracted inside 4 of the space delimited by the chassis 2, and thus limit the external bulk of the trolley 1, or deployed outwards 5 in order to make the accessories accessible and visible. A trolley 1 according to the invention comprises, in particular and preferably for each level of movable storage supports 3b, a plurality of such supports 3b distributed regularly-notably at the same height- and symmetrically around the service 1, and the supports 3b mobile - in particular and preferably of the same level - are associated with chassis 2 so that their deployment and retraction paths are symmetrical around the service. 1, so that these supports 3b are always, and even in the deployed position, symmetrically distributed around the service 1. The balance of the service 1 is therefore not modified during the retraction and deployment maneuvers. The deployment and retraction paths are preferably symmetrical around a vertical passing through the center of gravity or in the vicinity of this center of gravity of the service 1. Thus, this center of gravity is not or only slightly modified during deployment and retraction maneuvers and balance

is not changed.

  The fixed storage supports 3a, 3b rigidly associated with

2618 3 6 5 4

  motionless to the chassis 2 are also regularly and symmetrically distributed around the service 1, in particular symmetrically around a theoretical vertical passing through or at the voltnnage of the lift center of the service 1, so that the vertical of the center of gravity is confused with or close to

  the vertical of the lift center.

  According to the invention, the movable supports 3b of the same level are mechanically associated with each other by means 6

  association -including at least one pentograph-

  permanently imposing a symmetrical configuration of these supports 3b around the service 1 - in particular around the theoretical vertical passing through the lift center -. Thus, a retraction movement in deployment gives one of the mobile supports 3b automatically generates a retraction movement or deployment of the other mobile supports of the same level in the same proportions and symmetrically with respect to the service 1 - in particular relative to the vertical of the

lift center-.

  The center of gravity of the mobile supports 3b of the same level passes through the vertical of the lifting center or at the flights

  from this vertical, and at least by the lift surface.

  Classically designated here and thereafter by "lift center", the barycenter of the lift surface of the

service 1.

  Preferably, the supports 3 of the same level are regularly distributed around a theoretical vertical passing through the lift center of the service, and the deployment and retraction paths of the mobile supports 3b are symmetrical around the theoretical vertical passing by

  service center of gravity 1.

  In the preferred embodiment shown, each mobile support 3b consists of a horizontal plate associated with the chassis 2 by means 7 of rails, slides, rollers or the like allowing deployment to the outside 5 and a retraction to the inside 4 in horizontal translation of this

2618 365 6 5

tray 3b.

  The various mobile storage supports 3b of the same level all have the same shape and the same dimensions to constitute the same portion of storage support and classification of a level of the service 1 according to the invention which preferably comprises, at a given level, either only mobile storage supports 3b retractable -and can be deployed, or

  only fixed storage supports 3a or 3c.

  The chassis 2 is constituted by a horizontal fixed lower plate 3a, by two uprights 8 in the form of rectangular plates, rigidly associated with the peripheral edges 9 of the lower plate 3a to extend vertically, upwards, facing one of the other and parallel to each other, and a horizontal fixed upper plate 3c rigidly associated with the upper part of the uprights 8 so as to be less substantially opposite the lower plate 3a, the mobile storage supports 3b being associated with the amounts 8 between these two

fixed plates 3a, 3c.

  The two fixed plates lower 3a and upper 3c advantageously have the same shape, in particular at least substantially rectangular. The rectangular uprights 8 are rigidly associated with the fixed plates 3a, 3c by their edges 10 of shorter length extending in parallel and over a limited median part of the peripheral edges 9, 12 of the fixed plates 3a, 3c, the edges 1l of greater length of the uprights 8 extending vertically between the fixed plates 3a, 3c. The uprights 8 therefore do not run over a whole face of the trolley 1 and extending horizontally only part of the storage supports 3. Thus, these supports are better accessible and visible from the outside 5. The weight and the cost price of service 1 are all the more reduced. The chassis 2 does not have any other structure extending vertically than these structures 8. The trolley 1 according to the invention as shown has storage supports 3 on three different levels: a

2618 3 6 5 6

  lower level constituted by the lower fixed plate 3a of the chassis 2, an upper level constituted by the upper fixed plate 3c of the chassis 2, and an intermediate level consisting of two movable horizontal plates 3b of the same force and dimension extending in the extension l one of the other enters

the two amounts 8.

  Preferably, the lower fixed trays 3a and supereur 3c have the same rectangular shape and the same dimensions and in that the two intermediate mobile trays 3b form in the retracted state a rectangle of the same shape and dimension as the fixed trays 3a, 3c . Each movable plate 3b corresponds to half of a fixed plate 3a, 3c, and forms half of a level

of intermediate storage.

  The mobile trays 3b are preferably associated with the chassis 2 by means 7 similar to those which would be used for drawers with extension. For example, these means 7 of association consist of rails 7 integral with the uprights and guide rollers with horizontal axes associated with the side edges of the plates 3b to cooperate with the rails 7. According to the invention, the two mobile plates 3b are associated with the uprights 8 by the same horizontal rails 7 integral with the uprights 8 and rigidly associated with these uprights 8, each plate 3b comprising guide rollers cooperating with these

  rails 7. A rail 7 is therefore common to the two movable plates 3b.

  The service 1 comprises in this case two such rails 7, each rail 7 being associated with an upright 8 and this, so as to extend horizontally substantially halfway up the upright 8 against and

  parallel to its inward-facing side 4.

  The two intermediate movable plates 3b are associated with each other by means 6 of association which cooperate with their internal edges facing '13. In the preferred embodiment shown, the two intermediate mobile plates 3b are associated l to each other by a pentograph device 6 whose central point 14 is articulated to a cross member 15 of the frame 2 extending horizontally perpendicular to the uprights 8 between the two horizontal rails 7 for guiding

2618 365 7

  trays 3b. The two free ends of the pentograph 6 are associated respectively articulated with the two internal edges 13 of the movable plates 3b. The pentograph 6 can be simple, and then forms two deformable parallelograms having a vertex

  common and adjacent sides of the vertex in extension.

  In this case, the pentograph 6 consists of two rigid central rods hinged to one another and to the cross member 15 of the chassis in their middle 14 forming the central point of the pentograph. On each side with respect to the central point 14, two extreme rigid rods whose length is half that of the central rods, are articulated by one of their ends respectively at the free ends of the central rods and by their other end one at the other and in the middle of the internal edge 13 of the movable plates 3b. The pentograph 6 can, as a variant, be multiple and form a plurality of deformable parallelograms having two by two a vertex and sides adjacent to the common vertex in extension. The central point 14 of association with the cross-member 15 of the chassis 2 is always a vertex common to two parallelograms, and the

  pentograph is symmetrical with respect to this common vertex 14.

  Each fixed or mobile tray 3 for storage advantageously consists of a metal cover 16 to which recesses 17 calibrated tool holder are rigidly associated. The lower plate 3a, which is less accessible, may not include such housings 17, but simply a horizontal plate 18 for

install loose accessories.

  The trolley 1 according to the invention preferably comprises rolling means 19 associated with the lower plate 3a of the chassis 2 and making it possible to move the trolley 1 as a whole by making it roll. These rolling means advantageously consist of four associated wheels articulated at the four corners of the frame 16 of the lower plate 3a and preferably comprising integrated braking means 21. The lower plate 3c is provided with a guide bar 20 making it possible to roll the

service 1.

2618 365 8

  Each movable intermediate plate 3b is advantageously extended towards the outside 5 by a gripping and protective bar 22 extending parallel to the outer edge 23 of

  this plate 3b and rigidly associated with this edge 23.

  Preferably, the trolley 1 according to the invention comprises an upper stage 24 rigidly associated and fixed above and at a distance from the upper fixed plate 3c, this shelf 24 making it possible to temporarily deposit accessories during use without storing them in a support 3. The upper shelf 24 can be associated with the upper shelf 3c by two uprights 25 extending upwards from two corners of the shelf

  upper 3c, and by brackets 26 associated with the uprights 25.

  Trolley 1 according to the invention can be used in the following way. To move it, the movable plates 3b are retracted inwards 4 and the brakes are released 21. In this state, the outer edges of the fixed plates 3a, 3c and the space requirement of the service is minimal. The movement of the trolley 1 can be done without danger to the place of use of the tools or accessories. The braking means 21 are then blocked and the mobile platforms 3b deployed. In this state, the storage supports 3 are perfectly visible and acceslbles, and therefore also the tools or accessories. The bars 22 associated with the mobile platforms are rounded and protect the user if he

  came to bump against the movable plates 36 deployed.

  The balance of the service is perfectly preserved, even at

the deployed state.

  The trolley 1 according to the invention can be the subject of numerous variants obvious to a person skilled in the art, in particular as regards the

  number, the shape of the nature of the fixed or mobile supports 3.

  In particular, the mobile trays 3b can be replaced by drawers. Furthermore, the invention can be applied in other technical fields than workshop furniture, for example for making trolleys for

  laboratory accessories or office or other supplies.
