Description

The invention relates to a locking device for a rack

  several floors with separators

  self-adjusting stages, in which the maneuvering of separa-

  stages is performed by means of a movable control device. Multi-storey shelving was realized at

  self-adjusting stage separations comprising for the maneuvering

  The invention relates to stage separations, movable control members, by means of which the stage separations are kept locked in a tilted position, and which unlock these separations successively during their displacement of a step. In this way, the floor separations take a

tilting position.

  The displacement of the control members can be ensured by means of a motor, or they can function automatically when the phases of raising and lowering of one of the movable control members derives from the movement of the

  floor separations. Following this process, the

  mobile devices are supported by their cleats on

  rectilinear arms of the shortest separations of stages.

  The disadvantage of these straight surfaces of the short arms of the stage separations lies in the fact that at the following movement on one stage, the lowest separation is locked in its tilted position on an arm

  very short. This is why this process requires a great deal of

  manufacture as well as a precise adjustment of the game between

  a locking tab and the bearing surface of the separa-

  floor. Frequent use makes this game larger by wear, and, as a result, the first step separation in a load can be particularly diverted into the

  load storage area, which can cause

  when you store equipment.

  These disadvantages can be remedied by means of the device according to the invention, the stage separations of which

  self-adjusting devices are maneuvered by means of a

  vertically movable mandrel and rows of front cleats and

  with constant inclinations, and successively

  stop on the short ends of two-armed levers

  tiltable stage separations.

  The principle of the invention lies in that the arms

  shorts are provided with a cut in the area of the front cleats, and that the rear part of this

  short arm has the shape of a beveled support surface. The in-

  size is connected to a beveled bearing surface of the short arm of the step separation by means of a beveled connecting surface, the length of which is equal to 1/5 and up to 1/2 of the height of the distance from the floors. The angle formed by the

  two bevelled surfaces are between 140 and 1500.

  The advantage of this arrangement lies in the fact that it requires less manufacturing precision in comparison with locking devices of known types.

  so far, and that the security of their operation is now

  holding even though their parts are partially worn. He is in

  besides very easy to obtain an optimal setting of this device.

  The invention will be better understood with regard to the

  description hereafter and the attached drawings, representing a

  Embodiment of the invention, drawings in which - Figure 1 shows a sectional view of a rack column and a support column, relating to a group of self-adjusting rays with several partitions in stages in separate operating positions; FIG. 2 shows on a larger scale an appropriate stage separation with a notch for a

locking tab.

  The support portion of a multistage racking unit is constituted by two columns, a rack column 1 and a support column 2. In the rack column 1, holes are made at regular intervals for plugs 3 , on which are placed so as to tilt, the separations 4 stages. These stage separations 4 are formed by two-armed levers, with a long arm 5 and a short arm 6. The support column 2 is

  provided with cleats having the same spacing as the plugs 3.

  The rack column 1 is provided with support strips 8, on which a movable sliding control member 9 is based. This sliding control member 9 is provided with front stops 10 and rear catches 11. The spacings between the front catches and between the rear cleats are the same but

  their distance is shorter than the value of a step of

  The device operates in such a way that the stage separations 4 can take up three basic positions, namely, a bearing position, which is illustrated in FIG. the first and second stage separations 4 from the bottom, a tilted position shown by the third stage separation from the bottom, and a raised position

  illustrated by the two upper storey separations.

  The movable control member 9, the weight of which exceeds the tilting force of a separation 4 of free stages is provided with rear stops 11 which support, when

  they come to touch the separations of floors 4, on the surfaces

  these support 15 of the highest charged stage separation 4. The front cleat 10 advances on the tilted stage separation 4, in a notch 13 which arrives by its depth to below the axis of the plug 3. The rear cleat 11 of the control member 9 mobile maintains the separation of stages 4 in the desired tilted position. The front cleat 10 of a plug located above at the same time locks the separation of stages 4 located above in a raised position. The rear tab 11 of a lower plug rests on the support surface of the short arm of the stage separation 4 which is in the bearing position, and thus determines the position of the tabs 10 and 11 of the control member 9, with respect to

  all other floor separations 4.

  When a load 16 is lifted, there is a tilting of the stage separation 4 above this load 16 on an angle such that the front stop 10 stops sliding on the notch 13 and rests on the surface connection 14 inclined. The weight of the movable control member 9 exceeds the

  the weight of the two separations of stages 4, that is to say of the separa-

  tilted stages and the separation of floors that comes

to be moved.

  The floor separation that has just been lifted automatically takes the raised position. The separation of stages 4 which has just been discharged is raised at the same time on an angle limited by the position of the rear stop 11, and

  the appropriate movable control member 9 descends on the separator

  Charged 4 stages down. The beveled connecting surface 14 of the short arm 6 of the separation

  4 forms a transition between the notch 13 and the over-

  support face 15 and decreases the wear of the front cleat 10. The cycle is repeated during the subsequent lifting of a load 16

from the lower floor.

  When the load 16 is placed on a shared rack

  bearing automatically separating stage stages 4, this load 16 is placed on the stage separation 4 which is tilted. When it is loaded, this separation 4 takes the carrying position in which it relies, by its locking notch 12, on the support tab 7 of the support column 2: At the same time the separation of stage 4 goes back by means of its bevelled surface, the control member 9 movable by one degree. During this rise of the movable control member 9, the next higher separation 4 is unlocked, and, due to the displacement of the center of gravity, it tilts in its limited tilting position by the rear stop 11 of the body mobile control unit 9. When another load 16 is placed on the separation of stages 4 plus hau1X, the movable control member 9 rises again by one degree, which causes the tilting of the separation of stages

4 higher.

  The inclined connecting surface 14 makes it possible to raise the separation of stages 4 in the tilted position more rapidly than if this separation 4 were raised completely by the load 16. The locking notch 12 which is at the end of the long arm 5 securely connects the rack column 1 and the support column 2 together, which increases the rigidity of the set of two columns. When projecting the construction of shelving groups, it is advantageous to arrange the equipment of the shelving column 1 and that of the support column 2 in a single column, so that it is possible to form

  whole batteries of columns from radiation units

medley.
