Definitions
- the subject of the present invention is a device for vertically moving one or more objects while retaining their orientation and their positioning defined initially.
- Such a device will find, without limitation, a particular application in the field of store layout, in particular for hanging posters as well as advertising objects or articles offered for sale.
- the suspension of such objects or articles is carried out through wire elements, or strands, hung on the ceiling of the room to be equipped.
- the most successful of the devices comprising these wire elements are associated with winch-type winding means which facilitate the handling of these objects or articles, that is to say the hooking and unhooking operations, by enabling them to be bring it up to human height.
- these devices comprise only one strand, it is easy to adjust the height of the objects or articles hung, but it is however preferred to hang such objects or articles by means of several strands to prevent them from starting to rotate, and / or to give them a particular orientation.
- these devices comprise several strands, in particular two, these have identical strokes and, except for having an object or article having hooking points perfectly aligned horizontally, or calculating how much to shorten some of said strands and to carry out said shortening, it is difficult to vertically move said objects or articles while retaining their orientation and positioning initially defined.
- several devices with a single strand of suspension are generally used, controlled individually, possibly simultaneously by means of an automaton.
- the present invention aims to remedy these various drawbacks by proposing a device for vertically moving one or more objects while retaining their orientation and their initially defined positioning, of simple and inexpensive design.
- the device for vertically moving one or more objects while retaining their orientation and their positioning defined initially according to the invention comprises a shaft capable of being rotated by a motor means for winding or unwinding at least two strands used for the suspension of the or of said objects, and it is characterized in that said shaft carries several winding modules, one for each of said strands, each of said modules comprising an element intended to receive the wound strand, and linked to said tree through means capable of being disengaged.
- Such a device makes it possible to unwind, in the disengaged position, the required length of strand, then to freeze this length for each of the strands, and to keep the differences in length according to the winding and unwinding operations.
- each winding module comprises a first tubular element threaded on the shaft and integral in rotation with the latter, and cooperating with a second tubular element in free rotation on said shaft and serving as a strand winding reel, the cooperating parts of said tubular elements being able to cooperate by friction under the action of an elastic means pushing one of said tubular elements towards the other.
- the elastic means consists of a spring whose pressure is adjustable.
- the value of the threshold torque can be chosen so that the device functions as a torque limiter.
- each of the strands is associated with an abutment means of predetermined length, against which the object comes into abutment during winding.
- a device for vertically moving one or more objects while retaining their orientation and their positioning defined initially comprises a casing 1 containing a shaft 2 capable of being rotated by a motor 3.
- the device comprises several modules 4 for winding strands 40, 41 and 42.
- Each winding module is defined by a tubular element 43 threaded on the shaft 2 and secured in rotation to the latter, and a tubular element 44 also threaded on the shaft 2 but in free rotation, and intended for winding strands 40, 41 and 42.
- the tubular elements 43 and 44 cooperate with each other by means of a friction zone and under the action of a spring 45 which pushes the tubular element 44 towards the tubular element 43.
- the pressure exerted by the spring 45 is adjustable, by means of a screw nut system or the like.
- the device according to the invention makes it possible to suspend two objects, an object 5 suspended from the strand 40, and an object 6 suspended from the strands 41 and 41.
- the objects 5 and 6 are not to be hung from the same height, on the other hand it is necessary for the operations of hooking and unhooking to bring them to the height of a man.
- the device according to the invention makes it possible to obtain this result with a single device, since the length of each of the strands 40, 41 and 42 is individually adjustable.
- the length adjustment can also be obtained more precisely and automatically, by means of stop elements 10, integral with the casing 1, and against which the object 6 abuts when the strands 41 are wound up and 42.
- the stop elements 10 are of predetermined lengths depending on the object to be hung.
- the strands are unrolled, then the object or objects are hung there, the strands are then wound until the object or objects come into abutment against the elements 10 to adjust the lengths of the strands relative to each other which is allowed due to the declutching, they can then be unrolled to bring the objects to the desired height while retaining their initial orientation, as well as the positions of the objects relative to each other.
