Definitions

• the present invention relates to a tool for gripping and tightening the edge of a heavy hollow object, such as a container, for lifting and moving.
• the present invention aims to remedy these drawbacks by providing a particularly simple design tool making it possible to grasp the edge of a container such as a plant pot and to systematically tighten this edge during the natural movement of the lifting of the container.
• this tool for gripping and tightening the edge of a heavy hollow object, such as a container, for lifting and moving is remarkable in that it comprises an elongated support arm, an end part is bent downwards in the form of a hook and constitutes a first gripper jaw and a sliding mounted element on the support arm extending downwards, opposite the hook-shaped part of the first jaw, constituting a second clamp jaw so that in the clamping position, the end of the first clamp jaw and the lower end of the second clamp jaw are respectively in contact with substantially opposite points, respectively located on the surfaces internal and the border of the object.
• FIG. 1 is a vertical sectional view of a gripping and tightening tool. the edge of a container, according to the invention, in the gripping position,
• FIG. 2 is a view in partial vertical section of an alternative embodiment of the gripping and tightening tool
• FIG. 3 is a partial vertical section view of another alternative embodiment of the gripping and tightening tool
• FIG. 4 is a sectional view taken along line IV-IV of FIG. 3,
• FIG. 5 is a partial vertical sectional view of another alternative embodiment of the gripping and tightening tool.
• FIG. 6 is a partial representation on a larger scale of a last variant of the gripping and tightening tool.
• FIG. 1 a gripping and tightening tool 1 according to the invention engaged with the edge R of a container such as a flowerpot, having a bulge at its upper end.
• the tool comprises two elements, the end parts of which constitute the two jaws of a clamp, namely a support arm 1 and a counterplate 2 mounted sliding on the support arm 1.
• This support arm 1 can be constituted by a solid cross-section bar rectangular cross section or by a profile of any cross section.
• the support arm 1 comprises a straight main section 1a, of great length, carrying a handle 1b at its end, and connecting to an end part the hook-shaped curved downwards, this end part constituting a first clamp jaw .
• This extreme part comprises more particularly an intermediate upper section ld inclined downwards, connecting to the main section la and forming with it an obtuse angle, a vertical section le and a horizontal lower section lf.
• the plywood 2 comprises a substantially vertical main section 2a which is extended, at its upper end, by an upper section 2b pierced with an opening 2c through which the main section la of the carrier arm passes.
• the upper section 2b is inclined, relative to the vertical section 2a, so as to be perpendicular to the main section la of the support arm 1, to allow the sliding of the counterplate 2 on the support arm 1.
• the upper section lb is connected to an end section 2d which is bent towards the bottom and towards the handle 1b of the support arm 1, so that the end of the end section 2d is in contact with the upper surface of the main section 1a of the support arm 1.
• the vertical section 2a of the plywood 2 is connected, by a bend 2e, to an end section 2f.
• the hook 2e, 2f of the plywood 2 constitutes the second clamp jaw of 1 tool.
• the ends of the end section lf of the hook-shaped part le and of the end section 2f of the plywood 2 are advantageously covered with respective plastic ends 3.4 which are intended to come into contact with the internal and external surfaces respectively. from the edge R of the container.
• the opening 2ç of the plywood 2 through which the main section la of the support arm 1 passes has dimensions which are slightly greater than those of the cross section of the section la, in order to facilitate the sliding of the plywood 2 on the arm carrier 1.
• the tool according to the invention is placed in the gripping position shown in FIG. 1.
• the end piece 3 provided at the end of the hook-shaped curved part is in contact with a point A on the internal surface of the container and the end piece 4 provided at the end of the end section 2f of the plywood 2 is in contact with a point B of the external surface of the container, this point B being close to point A and situated at a slightly higher level. Consequently, when a lifting force is exerted on the handle 1b of the support arm 1, a force indicated by the arrow F in FIG.
• the upper section 2b of the plywood 2 is welded to a sleeve 5 sliding on the main section 1a of the support arm 1.
• This sleeve has an internal cross section slightly greater than that of the cross section of the main section 1a to facilitate sliding.
• the upper section 2b of the plywood 2 is welded to a jumper 6 sliding on the main section 1a of the support arm 1.
• This jumper 6 has a cross section substantially in the form of U inverted, and the lower ends of the two wings 6a, 6b of the jumper 6 which are folded down, are welded to the two lateral faces of the upper section 2b of the plywood 2.
• the upper core 6c of the jumper 6 extends in direction of the handle 1b of the main section 1a of the support arm 1 over a distance greater than the thickness of the plywood 2. Furthermore, in the tool represented in FIG. 3, the elbow 2e extends over an angle of 180 ° so that the lower extreme section 2f and by consequently the end piece 4 which it carries extends vertically upwards, thus constituting a V-shaped hook. This arrangement makes it possible to ensure effective clamping of an edge of a container R devoid of a bulge at its end.
• the counterplate 2 is devoid of the hook 2e, 2f. and the lower end portion of its main section 2a extends vertically opposite the horizontal lower section lf of the hook le and at the level thereof. Furthermore, the plywood 2 is completely covered with a coating 7 of plastic.
• the end lf of the hook le is provided with a stabilizing cleat 8 and arranged perpendicular to the plane formed by the sections le and 1 f of the first jaw of the pliers, advantageously symmetrically on either side of the hook, coming in its clamping position to increase the support of the tool on the internal face Ri of the container R.
• a stabilizing cleat 8 which is horizontal come, in fact, to bear 9 on the internal face Ri, which promotes the vertical grip of the container by better controlling its tilting.
• the cleat 8 could be secured to the end of the hook lç_ on the same side, to the left or to the right of the horizontal section lf which, according to another variant, could be folded at 90 ° to fill the same function.
• the gripping and tightening tool according to the invention which has been described previously, can be used alone or with another similar tool to ensure simultaneous tightening at two diametrically opposite points of the container.
