The invention relates to those cabinets for stirrer cans of the type as used for the storing of cans that contain paints etc. to be maintained under stirring.
The cabinets that are currently used comprise a plurality of shelves arranged one above the other, and having a bottom portion that is provided with driving heads of the small blade type, which driving heads cooperate with fingers arranged on the cover of each can and used for driving a shaft passing through this cover and supporting a stirring screw or the like.
In order to prevent rotation of the cans on the shelves, fixed or movable protruding pins are provided, which are used for securely retaining the base of the can. These protruding pins are often harmful and can cause damage to the cans, particularly when the same are made of synthetic material.
The protruding pins or other means for locking the cans have also the important drawback that they make difficult the cleaning of the shelves to which they are fixedly connected. Moreover, in case of leakage of the can, the apertures provided in the shelves for making or positioning the protruding pins allow flow of paint from one shelf to another shelf.
The invention relates to a new driving head for stirrer cans which allow the use of smooth shelves without any particular member to be provided on these shelves.
According to the invention, the driving head for stirrer cans each comprising a small blade driven by a first shaft and cooperating with fingers for driving a second shaft of a stirrer located in a can, is characterized in that the fingers protrude from a plate engaged in a grip that is a part of a body having a general shape like a swan-neck which is arranged beneath a shelf, this body having an upper portion that is penetrated by the first shaft that carries and drives the small blade as well as means that prevent rotation of each stirrer can.
A driving head for a stirrer can, the stirrer can comprising a cover with a rotatable plate having upwardly projecting fingers and further comprising a stirrer inside the stirrer can, the driving head mounted beneath a hollow shelf, according to the present invention is primarily characterized by:
The driving head may further comprise anti-friction means positioned between the grip and the rotatable plate.
The body preferably comprises a protecting hub of a substantially circular shape positioned closely above the blade.
The driving head may also comprise a drive pulley connected to the driven shaft, the drive pulley positioned within the hollow shelf, wherein the hub comprises a sleeve and a bearing member mounted in the sleeve and wherein the driven shaft is guided in the bearing member.
The driving head may also include a spindle connected to an end of the shaft below the hub, the blade pivotably connected to the spindle, the blade having a bottom portion with a concave cutout to prevent wedging the fingers of the operator.
Preferably, the means for preventing rotation of the stirrer can is a pivotable stirrup connected to the body, the stirrup engaging a portion of the cover of the stirrer can for limiting rotation of the stirrer can after placement on a shelf below the hollow shelf to which the body is connected.
The body preferably comprises a bearing member and the stirrup is connected to the bearing member, the stirrup comprising a yoke with studs for connecting the stirrup to the bearing member.
The grip advantageously has means for supporting the cover and the stirrer can.
The means for supporting are lugs connected to the bottom side of the grip and projecting inwardly.
The cover has preferably a bottom portion and the hollow shelf has a grip support for engaging the bottom portion of the cover.
The present invention also relates to a stirrer can for cooperation with a driving head mounted beneath a shelf. The stirrer can according to the present invention comprises:
The can may further comprise a spring with a first and a second end, the stirrer comprising a shaft and a stirring screw at an end of the shaft remote from the cover, the spring coaxially placed on the shaft and supported with the first end at a bottom side of the cover and with the second end at the stirring screw.
The invention also relates to a cabinet for stirrer cans. The cabinet according to the present invention is primarily characterized by:
At least one of the hollow shelves has a bottom portion with two levels, such that the driving heads connected to the bottom portion are at different levels.
The shelves comprise raising members for raising the stirrer cans to a desired level.
Various other features of the invention will moreover be revealed from the following detailed disclosure.
Embodiments of the invention are shown, as non limitative examples, in the accompanying drawings, wherein:
The drawings, in particular
This arrangement makes it impossible for an operator to get a finger caught between a top portion of the small blade 14 and the body 10, in particular the hub 15, which is thus a safety measure preventing any risk of injury. Moreover, the hub 15 is used for fixing the body 10 under the shelf 3 by means of rivets or other equivalent means.
The stirring cans, such as the can 16, are comprised of a can container 16′ with a cover 17 that is penetrated by a shaft 18. The cover 17 has a top portion provided with various protruding parts, and in particular a pouring nose 19 as well as a working handle 20.
The shaft 18 has an upper portion provided with a circular plate 22 which is fixed by means of a tightening screw 22a and has a centering ring 21. The centering ring 21 has an annular shape, and the diameter of the centering ring 21 corresponds substantially to the diameter defined by the grip 11. The centering ring 21 can rotate freely or is made of an antifriction material, or still is coated with an antifriction material.
The plate 22 is provided with two protruding fingers 23 and with cans or ramps 24.
As shown in the drawings, in particular in
When a can 16 is positioned, the rotation of the small blade 14, driven by the shaft 7, causes the small blade 14 to necessarily bear by its two ends against both of the protruding fingers 23, which results in driving the plate 22 and, consequently, the shaft 18 of the respective can. The concavity 14a of the small blade 14 prevents any risk of wedging by staying with the fingers 23. Moreover, the presence of the cams or ramps 24 that are sloped in the direction of rotation of the plate 22 aids to the raising of the small blade 14 that continuously rotates.
In this embodiment, a unit formed by the can, the cover and the driving mechanism is thus suspended by the grip 11 without the can 16 being supported on a shelf 3. As previously, the can 16 is prevented from rotating by means of the stirrup 12, and the shelves 3 can be manufactured for having a top portion which is smooth and easily cleanable.
For preventing an axial displacement of the shaft 18 that drives the stirring screw 18a, it is advantageous to position a spring 27 engaged on the shaft 18 and bearing, on the one hand, on the bottom portion of the cover 17 and, on the other hand, on the stirring screw 18a. The strength of the spring 27 is chosen according to the weight of the can 16 and the product contained therein.
It is advantageous that the grip supports 29 which are made of a resilient material will be covered with an elastomeric material or the like so to form, on the one hand, a protection and, on the other hand, end protrusions 30 for retaining the can 16. The grip supports 29 are arcuate and have an angular opening greater than 180°.
It is moreover possible that the centering ring 21 is attached to the plate 22 and, in case, will be spaced therefrom by a ball bearing or the like in order that there is no friction between the plate 22 and the grip 11.
The invention is not restricted to the embodiments shown and described in detail, since various modification thereof can be carried thereto without departing from the scope of the invention as shown in the following claims.
