Abstract

This invention belongs to a wooden frame, designed for pictures and photographs, field.The purpose of this invention is to create a frame construction to reach a new aesthetical high of a product, keeping its endurance, and ensuring good operation efficiency and an optimal input of substances and power resources in production.It comes through the use of a new, never before used straight angle junction with overt and blind tenons in a frame construction. This junction sweats the frame, not using an angle for fastening any additional construction elements.The frame consists of four profiled wooden strips. On the ends of two strips, nests I are cut. The ends of the other two have two tenons each - visible and blind. The frame is jointed and agglutinated. The inner side of the jointed strips is machined in such a way that it makes a deepened step, into which the picture is put during the exploitation, and the front side is machined in such a way that the frame would get its aesthetical function corresponding view.The straight angle junction with overt and blind tenons gives the frame good resistance.The frame production efficiency comes through preparing and collecting the frames not one at a time, but a particular number y and only after collecting is the profiled surface processed separately for each product, together with a place for the picture.This kind of frame production method enables the use of substances and electric power. This technology is ideal for industrial production. The original frame construction determines its high aesthetical level.

Description

FIELD OF THE INVENTION The present invention relates to the production of wood frames for paintings and photographs.

There is a known frame for mirrors or paintings consisting of interconnected hollow profiles with elastic compression between the front and rear frame walls and the image. The front wall of the picture has a curb on the back, which forms a groove with the back wall for inserting the picture. This frame design allows for a strong fixation of the image in the frame. (a.l. SU # 1510834)

The disadvantage of such a frame is that it is complicated and expensive to construct.

Frame jointing is known where aluminum profiled strips with longitudinal grooves and inner cavity are joined with corner pieces. For additional durability, another connecting element is used - a hard plate with threaded holes, protruding and curved part with a hole on the diagonal. Connecting bracket with threaded hole at the intersection of its longitudinal axes and end-plates. The second joint is secured at the junctions of the strips and is connected to the bracket by a single latch. The other latch engages in the tapped hole in the plate, (a.l. SU 1699410)

The disadvantage of such a frame is also its complexity, labor intensive and expensive.

An angle joint is known, in which profiled metal frame strips are joined by a special corner with two inclined surfaces with threaded holes inclined in opposite directions. The bracket is fastened to the frame by screw fixers with the axis of the threads perpendicular to the inclined surfaces of the bracket (a.l. SU 1697755)

The disadvantage of such a frame is its complexity, expensive and labor-intensive.

Angle jointing is known in which the profiled frame strips with longitudinal grooves and the inner cavity are joined by a corner mounted in the inner cavity. Special screws with tapered head fix the corner to the strips. The bolts are symmetrically in the strip grooves and their heads are larger than the width of the strip groove.

the diameter of the part of the head is thus based on its conical groove edges (a.l

SU No. 1704752)

The disadvantage of such a corner joint is also the material and labor-intensive, expensive and complex construction.

There is a known picture frame consisting of profiled strips with grooves and a picture holder-elastic plate with two pairs of clamping steps and a connecting end. The profiled frame strips are firmly connected to each other at an angle. One has a smooth exterior surface and a perpendicular internal protrusion, the other a decorative curved exterior surface and an analogous protrusion. The cavity of the image is formed between the perpendicular internal projections of the profiled strip and one pair of bracket steps and the connecting end of the image holder. (a.l. WITH NO. 171802)

And the disadvantage of this frame is its complexity, labor intensive and expensive.

There is a known prefabricated picture frame consisting of profiled strips with grooves, connecting angles with angled holes and threaded elements with different thread directions. Profiled strips are shaped and have horizontal support steps. The angles have cantilevered protrusions on their inner sides and their outer edges resting on

horizontal support steps (a.l. SU No. 1706551). The length of this frame is also its complexity, expensive and labor intensive. constructions There is a known picture frame and for photos, consisting of profiled strips with grooves,

the picture holders in the grooves of the strips and the latches connected to the picture holders. Profiled strips are C-shaped and have horizontal top and bottom sections. The upper part has an external protrusion. The picture holders are L-shaped angles, which are connected vertically to the horizontal part of the profiled strips. The latches are threaded elements inserted into the horizontal part of the bracket, coinciding with its longitudinal axis with the axis of symmetry of the external projection (a.l. SU No. 1706552).

And the biggest disadvantage of this frame is its construction complexity, material and labor intensive.

There is a known picture frame consisting of profiled strips, brackets, fixing screws, mounted in brackets and a picture holder. The profiled strips are C-shaped, have horizontal lower and upper sections joined together by sloping countercuts forming an inner angle to each other. The lower horizontal portion has a vertical edge facing the vertical portion. The vertical portion, in turn, has a bearing area that is opposed to the rib in its position. The latch is inserted into the bracket so that its longitudinal axis coincides with the height of the inner corner of the strips. The picture holders are plates with threaded holes located on the locking threads and having the ability to move along the axis (a.l. SU # 1706553).

And the disadvantage of this frame is its construction complexity, material and labor intensive.

The current National Standard specifies 11 types of corner joints that can be used in the manufacture of wooden frames: with open, through-going double stud YK-1. open-sided double-seam YK-2, open-sided triple-seam YK-3, blind semi-concealed seam YK-4, open-sided semi-concealed seam YK-5, blind-concealed seam YK-6, concealed-seam YK-6 with blind and YK-8 circular studs, diagonal joint with YK-9 blind stud, YK-10 diagonal joint, YK-11 diagonal stud.

The closest to the given is the known angle joint with the open-through double-stud YK-2. (rOCT 9330-76 OCHOBHblE coejiHHeHHH aerajieft H3 jpeBecHHbi h jipeBecHbK MaTepuajioB. Τηπμ h pa3Mepbi)

This and other angular joints listed above are complex in design and labor intensive. A frame with such an angle joint is expensive, aesthetically unattractive, not durable enough.

The object of the present invention is to create a frame structure that allows to achieve a high aesthetic level of the product, while maintaining its high durability, at the same time ensuring good work efficiency and optimal consumption of material energy resources in its manufacture.

The goal is achieved by using a straight angle joint with open and blind studs, which has not been used until now. Such a joint allows reliable operation of the frame, eliminating the use of any additional structural elements for corner fixation, and finishing the rectangle from large planes cut to the thickness of the frame.

The frame consists of four profiled wooden strips. The ends of the two strips have slots 1, the other two have two stitches at each end, threaded and glued with wood glue. The inner side of the folded strips is milled to form a recessed stage into which the painting is inserted during operation and the facade side is milled to give the frame an aesthetic function.

The presented graphic material shows the construction of the frame from the side (fig. 1), from the front (fig. 2), facade side (fig. 3), structural details (fig. 4,5), back of the frame. part (fig. 6).

The frame is assembled in the following ways: x mm thick boards cut to axb mm in two pieces 1 and dimension cxb in two pieces 2 with polished one plane and grooves in it for dxc mm details 1 and two removable dimensions g for parts 2, greased with wood glue and distressed. The outer planes of the resulting rectangle are ground to the dimension cxm mm. Cut the rectangle into workpieces of the desired thickness. The cut surfaces of the workpiece are sanded to dimension H and milled with a selected milling cutter, for example radial, along the perimeter of the workpiece R mm (sketch 6), and the opposite side along the perimeter of the workpiece n mm (Fig. 6).

The durability of the structure is achieved by the use of a straight angle joint with open and blind tines.

Frame production efficiency is achieved by starting the framing and assembly of frames, not one at a time, and then, after a block has been assembled and cut, a specific profiled surface and place for inserting a picture or photograph.

This frame design allows for very economical use of wood and efficient operation of woodworking machines, thus saving electricity. The proposed frame is very suitable for industrial production due to its simple construction and high productivity.

The original frame construction results in a very high aesthetic level.
