Definitions
- the invention relates to a multi-purpose magnetized device which is hereinafter referred to as a magnetised half-pole for both immobilizing an object on a magnetic surface or grasping an object.
- Magnetic surface means the surface of an object which is subjected to a magnetic force under the effect of a dipole magnetic source.
- the objects made of ferro-magnetic materials are part of these objects which we call the magnetic surface surface, ie surface on which a magnet can be glued by magnetic attraction
- magnetic device By magnetic device is meant device comprising magnetic materials distributed or traversed by an electric current so as to create a magnetic field characterized by the appearance of North and South poles on at least one of its surfaces, We call, subsequently, such a surface of the magnetized surface device.
- the attachment of parts, sheets, fabrics or objects on a worktop is traditionally performed using fasteners integrated in the work plan.
- the work plan must be arranged to receive them (opening, projection, grooves for fixing the fastening means to the worktop).
- the attachment points are therefore integrated in the work plan. Their position is predefined and fixed except to implement complex rail devices or sliding systems to fix a room anywhere on the worktop. These devices are then complex to implement, especially on large work plans.
- the use of permanent magnet fasteners is not widespread. It is limited to low intensity magnets (eg on boards
- Magnetic because of the difficulty to take off or correctly position a magnet of greater intensity on a work surface-
- the strong permanent magnets also cause constraints during their transport because of the permanence of the magnetic field and of the attraction force resulting from it.
- the present invention overcomes these disadvantages. It allows positioning points anywhere on a worktop or object made of magnetic material, without imposing a predefined position. It adapts to any worktop, whatever its size and configuration. It allows precise positioning of the attachment point on the work surface.
- the device of the invention which we call a magnetized half-clamp, consists of a magnetized surface (1), a lever arm (2) and a pivot line (3) located between the magnetized surface and the lever arm.
- the magnetic surface of the magnetic half-gripper is intended to be brought into full or partial contact with a work plane or a partially or totally magnetic object (4).
- the magnetic attraction force is exerted mainly between the magnetized surface ⁇ 1) and the work plane or the object (4).
- the worktop is a surface that is not necessarily flat.
- the magnetic half-clamp allows the immobilization of the workpiece (5) on the worktop or the object (4), the workpiece being wedged between the magnetized half-clamp and the worktop or the object ( Figure 4 ) under the effect of the magnetic force.
- the lever arm (2) allows easy detachment of the clamp from the surface by pivoting about the pivot line (3) of the clamp ( Figure 2).
- the pivot line (3) e ⁇ t at any time, the axis of rotation of the device passing through the contact point or points between the magnetized surface and the work plane.
- the magnetized surface (1) comprises a line that we will call the pole separation line (6), this line being approximately the perpendicular to the magnetized surface of the barycentre of the south poles and the north poles of magnetization of the surface. We. find as great "force" of south pole on one side of the line of separation of the poles that one will find a "force" of pole
- the shape of the lever arm (2) is chosen to allow the user to exert a force substantially orthogonal to the magnetized surface or a torque relative to the pivot line (3) of the magnetized half-gripper.
- This arrangement avoids the sliding of the magnetized half-clamp on the worktop when an operator exerts an action on the lever arm.
- the shape can be adapted according to the coefficient of friction between the work plane and the magnetic half-clamp.
- the angle formed by the lever arm and the magnetized surface whose vertex is the pivot line (9) may have a value greater than 145 °. This particular configuration is shown in FIG.
- the line of separation of the poles (6) may be perpendicular or close to perpendicularity to the pivot line (3), which may itself be aligned or approximately aligned with the maximum lever arm (14), ie the segment of the lever arm orthogonal to the pivot axis passing through the point of the magnetized half-clamp at the furthest distance from the pivot axis .
- This configuration makes it possible to have a continuous attraction force between the magnetized surface and the work surface as the opening angle (7) between the magnetized half-pliers and the working plane increases. It further avoids that the magnetic half-gripper slips on the work plane when it opens, the pivot line remaining in contact with the working plane.
- the pivot line (3) can be a straight line. This configuration makes it possible to position the magnetic half-gripper on the work plane, then to open it then to slide an object between the magnetic half-gripper and the work plane which is wedged against the pivot line (3). According to the particular modes of realization adopted:
- the pivot line (3) can be materialized by a stop of the magnetic half-clamp, especially if this pivot line is used to position objects stuck under the magnetic half-clamp
- the pivot line may have a section > curve, this curved section may include devices, wheels, balls, or other on its outer edge, facilitating the movement of the half-gripper once it open on the work plan
- the pivot line may have a groove (12) for wedging the magnetic half-clamp on the work plane or the object or wedge two magnetized half-clamps together by introducing an axis (13) in the groove ( Figures 20 to 25, view of pirofil)
- the line of separation of the poles (6) can constitute approximately an axis of symmetry of the geometry of the magnetized surface. (1), the magnetic fields passing through two symmetrical surface elements with respect to the pole separation line being opposed with consequently an antisymmetric distribution shape of the north and south poles on both sides of the pole separation line. .
- This arrangement then also makes it possible to constitute a magnetized clamp by assembling two identical or different magnetized half-clips (FIG. 9).
- the symmetry of the device allows in this configuration a. automatic centering of the two half ⁇ pi nces relative to each other, the ⁇ Pole separation lines of the two half-pliers being approximately merged when the clamp is closed. The pivot line is then the opening axis of the clamp.
- the magnetized half-clamp may comprise an elastic claw (8) making it possible to fix thick pieces while maintaining a high clamping force.
- the elasticity of the elastic claw (8) is adapted to the force of attraction developed by the magnetized surface (1) at the lever arm between the elastic claw and the magnetized surface (2) and the thickness range for which the device operates.
- the device according to the invention is particularly intended for fixing objects on a work plane, in particular a large worktop, or on a magnetic board.
