Description

FEET FOR LIGHT EMITTING DIODE FRAME

  Various types of displays for frames and paintings are currently known. Most are called shop window easel easel, tripod easel, table, and are made of wood, plastic, solid oak, wrought iron easel or wire bent, curved, chrome, brass plated.

  The technical field is that of framing, particularly that concerning the support and maintenance of tables and various works on appropriate displays.

  Historically, the painter's work is done on canvas, then varnished and arranged in an empty frame and whose artistic aspect is actively sought to highlight the work, agree with it by giving it an additional particular or complementary character .

  Although many works are made on canvas stretched by wooden frames, which are held in the rabbet frames, others also, in large numbers and in different forms, are performed on other media, almost always requiring a presentation and a traditional keeps.

  These works are therefore totally dependent on their display of media and are installed on maids all as diverse as known, such as lecterns, easels, portico desks, and other lines, chair rails, hooks, pitons, and clashes in multiple forms.

  These creations or works in general, therefore, have the major drawback of being unable to be autonomous in their presentation, and require an ancillary system making them presentable as to their exposure, except if it is for photo frames that for a century , are equipped with a rear foldable cardboard leg with ribbon, this for reproductions for family use.

  It is the same for some frames containing new patterns with electrical units sometimes operating quite heavy and quite complex.

  All these sets are therefore entirely dependent on supports for their presentation or operation, and especially there are no original or multifunctional feet particularly dedicated to frames with decorative electronic low voltage lights.

  The invention aims to solve this type of very particular problem, by assigning to a given frame, a set of typical and functional feet, which makes it autonomous of all types and other supports, and giving it a possibility of exposure and The present invention relates to the production of feet to make autonomous the maintenance of a frame provided with light emitting diodes, with integrated control and adjustment system.

  These feet, object of the invention and which are two in number, are specific to each frame and allow a standing, totally vertical presentation of a frame containing various electrical light sets, such as LEDs. The feet according to the invention have a possibility of adjusting the height of the frame with multiple successive holes through the vertical support rods and a double bolting of these rods on brackets fixed permanently on a metal plate fixed to the frame, so to be able to adjust the height of the latter, in fixed steps.

  This very important innovation, finally makes possible the individualized presentation of the frame by only two vertical rods mounted and arranged with at least two horizontal rods of underbody, with at least one angle anti-tilting and anti folding by foot, this to avoid any risk of shearing or bending during low bolting, or during use.

  These brackets made of galvanized steel with high resistance, are arranged and bolted in several places, in the bottom of the upper vertical rod, and the middle horizontal low rod. 25

  The two square-rolled steel rods have a very slightly granular surface that allows the paint to be fixed and stabilized. For large frames, or other fixtures, the mounting sections may be different or non-square, such as rectangular and others, but in any case by adapting to aluminum angles fixed to a metal plate provided for them. receive and maintain them by fixations, as close as possible, contiguous to the said plate.

  These vertical rods can adjust the height of the frame at will 9 cm by thresholds or steps of 1 cm, or centimeter in centimeters, or differently depending on the drilling spacing envisaged. The rods used according to the invention are in rolled square steel 10 × 10 mm (2)

DESCRIPTION

  The dimensions of the legs for the basic model P100 are as follows: A) - high vertical rod, length 240 mm (7) B) - low horizontal rod, length 190 mm (8) C) - triangular square with right angle, 55 x 55 mm, thickness 1.5 mm (24) A) vertical rod The drilling of the upper part in M3, starts at 10 mm from the top end, and is formed by transverse passages (3) of the vertical rods, or ducts , and are repeated with a regular spacing of 10 mm to obtain 12 holes on one and the same side and which open on the opposite side, or over a length of 11 cm.

  the drilling of the two holes of the lower part M4 begins at 5 mm from the bottom edge for the first and 40 mm from the bottom edge for the second., these holes passing through the stem from one side to the other, and are all arranged on the same side stalk. The M4 holes are carefully milled deburred (10) and form the passages and holes (11) for fixing the foot square. The holes high and low are transverse, through and are all made on the same side to open on the opposite side. The high holes are made in such a way that with the arrangement of the holes on the (5) aluminum angles, and the fixing in the latter of the lowest transverse passages the vertical rods do not protrude or protrude from the top of the metal plate. frame (43) beyond the rods.

  Drilling and fixing at the top of the frame to be ensured in total stability 3 5 Moreover, the holes made on the vertical rods have the particularity of not being visible to the observer facing the frame, because of the completely masking position of the frame, taken in its entirety, and transversal piercing in some cases. The height or course of adjustment is about half of the total height of the metal plate used, the angles being placed at about half plus 5 mm.

  The vertical rods are treated in the same way, left or right, and their non-fixed length is directly related to the size of the frame and that of the metal plate.

  B) horizontal rod The drilling of the horizontal rods is also special, it comprises per rod: 2 holes in transverse M4 for fixing the bracket, the vertical rod and its positioning, holes 55 and 95 mm from the rear end 1 M4 transverse hole for cable lock (14) to 25 mm rear end.

  2 M4 vertical holes 8 mm non-through (44), for fixing circular pads (12) for loose protection, 12 mm in diameter, and 15 mm from each end 50 1 other vertical drilling M3 through the back to 30 mm for screwing frame foot (13) or sealing on metal, cement, in case there is a need to maintain a fixed position. the horizontal rods are treated left or right indifferently in the same way their lengths are adjustable according to the stability to give the frame used.

  C) Triangular angle with right angle M4 hole between 40 x 40 mm on the right-angle (38) sides at 5 mm at the longitudinal edge and 65 mm at the hypotenuse (41) side. They are mounted at right angles to the front face of the frame, and the side diagonally or hypotenuse facing back to ensure vertical continuity in the front. They have a thickness of 1.5 to 2 mm. the bracket (6) limits the setting of the frame down to 6 cm, the installation and the final assembly of at least one square uses various bolts through screws through (15,42) of different length, with externally oriented blind nuts (17) in the following bores.

  At point P1, (32) the screw passes through the Vertical rod, then the right angle square hole (38) and then the bottom hole of the Horizontal rod.

  At point P2, (33) operation lightened with only the top hole of the square and rod V At point P3, (34) the third hole of the square is used to fix it on the second hole M4 of the horizontal rod, to the rear.

  The brackets are obtained by 2 by sawing on the longitudinal axis of a 65x65mm square.

MOUNTING

  The role of these brackets is therefore to connect, secure, block, and thus avoid any risk of tilting or folding rods together, scissors. The two ends at 45 have their angles cut at a right angle to the width of the square, that is to say here 10 mm, The brackets are therefore an essential element for maintaining and cohesion of the foot, whose anti-tilting roles of the frame and anti folding in foot scissors or mounting rods on their bases, is essential.

  The brackets are mounted so that the right-angled side is placed under the front face of the frame, and the side slanted or hypotenuse under the rear face of the frame or metal plate.

  The size of the brackets and angles is not fixed, it evolves according to the different models and different forms of assembly, and to ensure above all the stability to the frame.

  Only the final assembly, there will be a difference in presentation between the right foot and the left foot 3, knowing that the vertical rods, rising must be screwed outside the angles for the upper part, but for the lower part is find positioned inward or center of the axis of the frame, relative to the horizontal rods, the latter being placed on the side, outwards This final mounting arrangement of the rods of the two feet, is intended to improve the stability 40 and the seat of the entire assembly formed frame mounted, otherwise quite heavy.

  The vertical rods are placed and bolted next to the horizontal rods, thanks to their holes M4, the bracket (6) taken and sandwiched (20) ensuring the connection and maintenance of the two rods together. The square mask and side view, the bottom of the vertical rod on its height, or about 55 mm, non-limiting other dimensions.

  Another assembly order also constitutes a significant change in the placement arrangements of the support rods, and is another very interesting alternative.

  This difference in mounting can exist by making the vertical rods are placed and placed on the horizontal rods, one above the other, and not side, that is to say that the 0 vertical rod is positioned on the horizontal rod, and at least a new square larger by the difference of 10 mm with the old model, will maintain solidly the horizontal rod to the vertical rod by conventional bolting.

  It is possible to keep the old M4 holes, and only the higher square, will carry a fourth hole M4, 2 vertical for the vertical rod and 2 horizontal for the horizontal rod. in this context, it is preferable to use 2 brackets or one on each side of the rods to keep tight sandwiched (between the brackets) which is intended to prevent inadvertent swaying of all by a shock in the plane of the square, for example.

  The size of the brackets can be enlarged but without this hindering or restricting the low position with the frame, of the order of 55 to 65 mm minimum for the model P 100, the bottom of the square being joined with the lower part of horizontal rod, which is placed on any flat part.

  The fact that the rods of the support are kept sandwiched allow other assemblies with the use of other thicknesses and with modified brackets, with multiple folds in shape or kind of steps, on both sides of the bottom vertical rod, which is also an amount, is an essential and fundamental part of the exploitation of the invention.

  The horizontal rod may have a shape and a non-square section, and be much larger size, for example 10x1 5,15x20, etc., it is always mounted to the outside.

  The thickness may also be different, but mass production will still require a form simple enough to implement. The material can be changed, and adapted to new possibilities of exploitation, such as reinforced plastic, glued wood, fiberglass or any other material with qualities at least equivalent to that of the laminate, this for all types of feet according to the l The horizontal rods are perpendicular to the vertical rods, and the facial plane of the frame or table, and pass under it, for the role of anti-tilt.

  An optional milling on the top of the angle bracket plate, of improvement, consists in the adjustable tilt (24) possible of the 2 vertical rods either towards the front or towards the back by a small milling in arc of circle on 30 degrees, 10 degrees forward (26) and 20 degrees backward (27), with special screws and nuts with adjustable vanes (25) to compensate for the possible unevenness of the pedestal, furniture , altar, etc., this improvement ensuring a new positioning of the frame in three limited dimensions of the inclination engravings are marked on (28) the top of the square, visible side.

  After cuts, the three elements thus prepared, cut, are polished brushed drilled, deburred, and are carefully degreased, repeatedly, then dried and painted with special paint hammered, (9) to the following colors, golden, silver, sky blue, jade green, ocher, champagne, burgundy, or other multicolored hues such as pastels, spangles, fluorescents, or various surface treatments, such as brass plating, chrome-plating, nickel plating, sanding, etc.

VARIATIONS

  An important mounting variant, consists of a different presentation with another 4 5 foot mounting type, to improve the stability and strength of the whole formed frame feet.

  This variant consists in mounting a second horizontal foot rod in parallel with the first (36) with possibly a second bracket so as to have and in order, a horizontal rod N 1, a bracket N 1, the vertical rod in the middle plus and the spacer (35) at the rear of the same foot thickness between the two rods, another square N 2, then the second horizontal rod 0 N 2, with a new bolt. complete set, set as for a normal foot, the rear threaded retaining screw of the rear passing through (30.31) of the cylindrical spacer (35).

  The base length of the screws (42) has been lengthened by 10 mm for the correct maintenance of the new assembly (29). Also, a mounting brackets in opposition, or 2 squares on either side of the vertical rod, superimposed at their right angle, with play catching on the thickness of this assembly, or opposite from their side right angle, requiring a larger cross section as well as a new hole in the lower part. This new foot which weighs nearly 0. 75 kg unit, provides an exemplary stability to the frame and its sliding is excluded because it is provided with 4 minimum pads or anti-slip supports This variant therefore lies in the case or there would be a assembly made with double horizontal rods, so a total of four horizontal rods for two verticals, two horizontal rods placed inward and two horizontal rods placed outwardly one on each side of each amount.

  This consists in introducing between the two horizontal rods, two brackets, plus the vertical rod in the middle, with a spacer for the correct bolting back of the brackets, the blind nuts being always placed towards the outside. The feet once assembled, at the Level brackets, are mounted and fixed against the outer side of the aluminum angles, between them and the rubber abutments (40) for fixing and protecting the metal plate.

  The vertical rods are used for their transversal holes and allow their displacement on aluminum brackets integral with the frame plate to choose and lock with screws and nuts, the height desired by the observer, each foot or vertical stem of the foot being fixed on a single aluminum angle, side free wing, opposite the central axis.

  It is necessary for this operation to have a long screwdriver, a key N 5, and to proceed very delicately, this to be done frame laid flat on a fabric so as not to damage it on its two sides or by multiple scratches on the dissipative plate and the feet or by untimely falls.

  The angles are drilled to the following dimensions for the vertical rods between the axis 20,20,20, or in fact two holes 20 mm apart, and in the middle of the longitudinal plane is 5 mm during assembly. There is therefore a transverse drilling of the vertical rod which is not occupied, it is free, and it is the one in the middle of the two which are used, but the fixing interval is not fixed and can be increased in multiples of 10 mm or other, the aluminum angles are prepositioned on the metal back closure plate, but can also be fixed after mounting the feet, by pop rivets (45) flooded head, for example .

  This interaxial drilling distance of the angles is very important when the stability of the frame on the rods, and if necessary it can be increased, as for example to reach either 15.30.15, or 10.40. 10 or 20.40.20 mm, or other with good on a possible lengthening of the total length of the angle up to 10 cm. Weight and stability are two important elements that must be constantly optimized, and absolutely mastered to validate the solidity and fixity of the whole assembly, and the section of the angle can go from 10x15 to 15x20, or 20x30 mm, etc. The vertical rods are held against the angles thanks to the transversal holes made in the rolled steel rods. These are placed, located between the vertical face of the angle or the wing of 10 mm and the bumper of low and possibly high protection rubber Two clamping washers with two nuts M3 brasses (16) maintain the rods 50 ( 4) vertical plated, clamped, through the transverse bores made, against the aluminum angles fixed to the aluminum metal plate, also playing the role of dissipative plate (39,43) of a semiconductor, transistor or here, a voltage regulator LM 317 T. The holes or passages or conduits are made transversely from one side to the other, in a straight line, on the steel rods, as well as for the drilling of the angle brackets and support, which represents one of the fundamental and essentially practical basis of the system for maintaining and adjusting the height of the frame by the aluminum dissipating plate attached to its rear.

  In all possible cases, there will always be cross passages, smooth or threaded for clamping the vertical rod on the angle by means of screws with or without nut.

  In the case of bores and or threaded transverse passages, only the screws will be necessary. The threads made as a result of the transversal bores allow electrolytic treatments. The angles of aluminum or other metal are fixed on the dissipating plate by an undesirable hardware of brass, head polished convex, to ensure the continuity of connection and thus support between the frame, whether it is wooden rod, plastic or metal rod, alloy ..

  The angles can also see their modified dimensions, metal rebate, and also for the vertical and horizontal legs of laminated solid steel, possibly stretched or angle or U-shaped type hollow square, which may undergo other surface treatments. All these various foot arrangements according to the invention relate to applications on both wood frames and 100% metal frames, thermo formed plastics, and others.

  These feet (1) resulting totally vertical and fixed at right angles to the angle and the horizontal rod laminated, give the best possible perception to the pattern represented by LEDs or light emitting diodes, the latter having unfortunately only a very low angle of aperture or emission limited to 30 degrees, and are perfectly visible only from the front.

  According to the invention, the three indissociable, interdependent and fundamental elements are the following: rolled steel rods corner brackets aluminum angles These three distinct components undergo different operations to fulfill the frame support function. This support is also completely removable, recoverable and bolts in all its assembly The vertical rods whose width, 1 'thickness can be changed, can lead to a slight movement of the angles to the center, but so as to always be positioned in below the rubber abutments for holding the metal plate by screwing on the back of the frame.

  These spacers rubber spacers ensure the convection of air by their thickness of 11 mm between the plate and the wall, the protection against the wall shocks on the anodized plate, also the wheel D24, 4 mm, or the 417 button, 7 mm, adjustment system.

  Likewise, they also protect anodised aluminum angles of 10 mm (10x15) height when mounted on a wall stud, always ensuring the natural upward movement of air on the plate, and its contribution to the air holes. aeration, low and high ...

  The brackets can also be used differently and in other ways, to have 50 other ways of maintaining feet, especially for the horizontal rod mounted on horseback. 10

  1) 2) 3) The bolted aluminum angles (18) and integral with the metal plate, ensure by the change of position of the vertical rods.

  The modification of the height of the frame, which can also have a mode of use and a modified form, particularly by other types of fixation, and forms of feet, by the type of maintenance that will be associated with it, large angles of 20x30, etc., and with the same method of tightening, double transverse screwing of each foot, in its upper part or upper stem.

  The feet (1) thus produced have an almost unlimited life, the bolting being in varnished brass to avoid any trace of oxidation, but may be in some embodiments, such Christmas tables (260x320mm), be replaced by rods in wood of much greater thickness or other to support the load, but always with brackets used in sandwich.

  According to the invention, there are therefore two types of sandwich plug for mounting the brackets, 15 - passive with taking at least one square between the two rods according to the invention, - active with taking the two rods at least between at least two brackets, on both sides of the rods, to maintain anti-shear, anti-reflexion, and anti-tip frame.

  The assembly with shiny brass bolts gives, in addition to the surface treatment or the hammered paint of the rods, a distinguished, precious seal which agrees favorably with all kinds of assembly formed of the frame, stick, with felt and diodes of multiple colors.

  These feet can support up to 20 kilograms unit, without shock or drop, and their massive appearance gives their function, an element of stability and visual comfort not insignificant, 2 5 especially since under and behind the frame is found no parasitic element specific to the attachment or maintenance of a third leg, tripod, stand, or various fasteners, but only under the middle of the frame, a current lead wire which is very quickly integrated into the general appearance.

  The G 250 model requires a laminated square of 12 x 12, or 14 x 14, with a length of 300 mm for the vertical rod, and 240 mm for the horizontal rod.

  The transverse bores of 4.3 mm diameter M4, on the vertical rod are continued up to 1 cm from the top end and stop at about 12 cm from the bottom end.

  The angle of 10 x 15 for the laminate of 10 passes to 15 x 20 or 15 x 25 for 14 x 14 mm square laminate. The thickness of the stop therefore varies upwards.

  The height of the vertical rods, is limited in that the frame fixed in the low position and the last holes, the top of the rod does not exceed the top of the frame or plate, or above the rod of the frame. The aluminum angles 2 in number are essential to the invention.

  The brackets which are 2 or 4 in number, and steel, are drilled in their three angles, and mounted according to the conventional diagrams namely clamping sandwiched between the rods with a square, or in case of mounted on horseback, that is to say the vertical rod on the horizontal rod, by sandwiching this assembly by 2 brackets on either side of these rods, rods and brackets drilled in the axes to be joined and maintained by a brass M4 bolt with blind nuts (17) according to the invention.

  In the case of use of wooden or non-metallic rods, the brackets used will always be metal, as well as the angles, the brackets have a dimension of 55 x 55 mm in right angle, and 65 mm of hypotenuse, with edges slaughtered model P 100 width of 10 mm, the same size as the thickness or section that the rod used, here is square of 10 mm According to the higher dimensions in rolled steel or otherwise, in squares mainly, 2 in 2 , ie 12x12, 14x14, 16x16 mm, etc., the size of the square used, at least one square, has a dimension or width increased by 2 mm for the angles cut, in relation to the width of the square, and moreover the lengths of the long sides of the right angles of 10 mm, are also increased to be related to this new thickness or the size of the square, or 5 in 5, or 10 in 10 mm.

  The two rectified angles (37) ground form the ends of the square, opposite the right angle. (38), and these felled edges always remain at the width dimension of the upper and lower shank where they are contiguous or sandwiched, or vice versa by sandwiching the shanks between two brackets.

  In the case of using a square larger than 10 x 10, the transverse passages have a new diameter which can spread from M3 to M4 plus a few tenths, about 0.3 mm being necessary to the free play of the screw used, knowing that there is a paint thickness plus a clearance created for the free movement of screws in the conduit, passage or drilling, but all these transverse holes can also be threaded and chromed with the entire rod.

  According to the invention, the realization of the feet aims to make the frame autonomous when 20 to its presentation, maintains, and integrate into its autonomy, in the practical realization of a self-supporting frame.

  These feet are an integral part of the presentation of a LED frame, and are not intended for other frames of any kind.

  The frames can be wooden rod or extruded plastic or metal profile 2 5 with notch system or reusable retaining rail for fixing the dissipating plate bracket brackets, which requires each time adaptations and achievements all too original and innovative

  The filiform, resistant and ponderous aspect of the feet according to the invention, they provide a very good adaptation, presentation, a solid mounting, an exterminât easy setting without any possibility of maladjustment, and a general integration excellent to any type of They have the function of maintaining individual and in a strictly vertical position and visible from an observer, different patterns of low-emission emission LEDs.

  Furthermore, they ensure a significant additional heat dissipation, by the fact that they are fixed to brackets integral with this aluminum plate. The feet according to the invention, formed of rolled square rods, drilled, screwed, are Thus, particularly intended to support and ensure the presentation of a table arranged with multiple light-emitting diodes, this thanks to fixing brackets permanently placed, and 40 which maintains it on a metal plate, whose original functions consisting of in heat dissipation, component support, rear closure of a frame, aesthetics of forms and presentation of quality, are totally preserved, renewed and improved. . 1 5 2 0 2 5 3 0 3 5 4 0
