ABSTRACT:
FIELD OF THE INVENTION
The invention relates to a support element and to a device for supporting and positioning a painting on a wall.
BACKGROUND OF INVENTION
When it is desired to hook a painting or a similar flat object such as a mirror on a wall, a cord joining the two uprights of the frame of the painting must generally firstly be fixed, or one or more rings must be fixed at the rear of the painting. The painting is then hung via this cord or this or these rings, on one or more support elements fixed in the wall, for example nails, plugs or hooks such as the one described in U.S. Pat. No. 2,940,712. This document describes a hook provided with a nail presenting a “V” shaped body which comprises a notched slot, as well as a tapering point and a head: a second threaded anchoring nail (or screw) extends through the notched slot; the first nail is inclined upwardly by an angle ranging from 35 to 45° with respect to the horizontal, while the second (anchoring) nail is inclined downwardly.
It is difficult to manage to position the painting precisely. In fact, when several support elements are used, unimportant variations in alignment may nonetheless provoke an inclined position of the painting detrimental to its aesthetic appearance and to the general presentation of the wall. When a single support element is used, the painting is then in even more precarious equilibrium, and may pivot accidentally due to the cord sliding around its single point of support, and take a considerably inclined position.
Furthermore, if it is desired to modify the position of the painting in height, it is necessary either to fix a new support element in the wall, or modify the length of the cord, which process is fastidious.
U.S. Pat. No. 2,791,388 discloses a device for supporting and positioning a painting, which comprises:
a support comprising two lugs, to be fixed to the wall by nails, screws or an adhesive, and comprising a threaded opening;
a body likewise comprising two lugs to be fixed to the frame by fixing members such as nails screws or adhesive,
two threaded rods fixed to the body and provided with a nut,
a base which may slide horizontally with respect to the support to allow a horizontal displacement of the frame.
SUMMARY OF THE INVENTION
One object of the invention is to propose a system for hooking the painting to the walls by its frame which is improved.
Another object of the invention is to propose a system for fixing a painting which is very simple and very easy to use.
One purpose of the invention is to provide a support element and a device for supporting and positioning a painting on a wall which overcomes the drawbacks mentioned hereinabove and allows an easy and rapid installation on a wall of any material and, an easy and precise positioning of the painting on the wall, as well as an efficient support of this painting without damaging the wall.
One purpose of the invention is to provide a support element and a supporting and positioning device which makes it possible to modify the position of the painting both horizontally and vertically, so that the painting integrates perfectly in its visual environment.
According to a first aspect, the invention consists in providing a support for hooking a painting, which comprises an element forming intermediate support to be fixed to the wall (by one or more means such as nails or screws), and an element forming a bracket adjustable in height with respect to said member and fixed thereto; when the element forming bracket is fixed to the intermediate support element which is fixed to the wall, the bracket projects on the wall and supports the object (such as the frame of the painting) by one of its substantially horizontal, so-called hanging faces or parts of the painting, which is protuberant with respect to the rear face of the painting, and which extends in a zone of the painting located above the center of gravity of the painting; the painting is thus hung by its said hanging face (forming for example part of an upper crossbeam of its frame) which abuts on the bracket; anti-slide means are generally necessary in order to avoid a movement of slide of the hanging face of the frame on the corresponding abutment face of the bracket.
An important advantage of the invention is that no fixing element is added to the painting since a hanging face integrated therein is used.
According to preferred embodiments:
said supporting and positioning device (for hooking or hanging) a flat object provided with a protuberant element on its rear face, on a substantially vertical surface, comprises:
an intermediate fixing body or element which comprises a threaded passage (or tapped hole),
means for fixing to said wall (to said surface) said intermediate fixing body or element,
an element for positioning (or adjustment) or vertical displacement and support of said object or painting, which comprises:
a central threaded part (or rod) which is adapted to extend through (and to cooperate with) said threaded passage, in order to be screwed or unscrewed over a stroke of at least 10 millimeters (for example from 20 to 30 mm),
a first end part (or lower end) which comprises a means for actuating said central threaded part in rotation, i.e. for screwing or unscrewing in said threaded passage,
a second end part (or upper end) which comprises a bracket element (on which may abut a substantially horizontal plane zone or face of said protuberant element of said frame of said object or painting, which is disposed in the upper part of said object, which first and second end parts are disposed on either side of said central part);
said element forming bracket (of said second end part) comprises on an upper horizontal bearing face, on which said frame may be hanged by its said horizontal plane face or zone, which comprises friction or friction or adhesion means adapted to cooperate with said hanging face of said frame, which means preferably comprise one or more (preferably tapered conical or pyramidal) tacks or brads adapted to penetrate at least partly (by marking or stamping) in said hanging face of said frame made of a material of low hardness, such as wood or a plastics material;
said body comprises at least one through hole (preferably two) or slot, extending between front face and rear face of the block, adapted to receive a curved metal blade forming one of said means for fixing said body to said surface, which blade is preferably essentially constituted by a portion of bent or rolled metal plate (or foil or thin section), which through hole or slot is substantially cylindrical, of circular section or not;
said body comprises at least two (preferably at least four) guiding through holes or slots, extending between front face and rear face of the block, adapted to receive at least two different means (for example three different means) for fixing said body to said surface;
said body is provided with two parallel, principal, large faces: a rear face in contact with the surface and a front face by which the fixing means are introduced in said holes or slots;
said holes or slots, as well as the lower and tipper faces of the body, are inclined with respect to the normal to a rear face for abutment of the body against said surface, by an angle included between 5 and 45 degrees, preferably ranging from 15 to 35 degrees, for example close to 20 to 30 degrees;
said device comprises a face for abutment against said surface for example integrated in said intermediate fixing body or element, which is adhesive;
said device further comprises a base or interposed adapter of flattened shape, for example in the general form of a shoe, which comprises integrated means for mechanical fixing or connection with said intermediate fixing body or element, which comprises a rear face in contact with said surface (whose surface is larger than the various surfaces of the faces of said body), which is coated with an adhesive, and said interposed piece or adapter further preferably comprises at least one and preferably at least two through orifices for guiding accessory means (such as tacks
