The subject of the invention is a scissor guide, applicable in the furniture industry, in various interior design projects, including interiors for didactic, business or commercial purposes, in residential premises interiors, in advertising and wherever a need arises for sliding surfaces. Such elements include mirrors, entrance doors, furniture fronts, drawers, hole plugs, radiator covers, wall decorations, paintings, graphic art pieces, masking frames for revision openings and others.

The solution, according to the invention, may also be useful in mounting and usage of didactic devices, such as pictorial boards, projectors, models and other. The guide bar, according to the invention, may also be applied in mounting and operation of a broad spectrum of advertising media, such as mobile boards, billboards, LED board panels and other.

From the description of the design submitted under no.W-113 302, whose description summary was published in the RP Patent Office Bulletin no. 25/2003, a mirror with a sliding assembly is known. The mirror has on the back surface attached articulated ends of at least one pair of levers. The other ends of the lever are attached in a push-pull fashion by articulation to elements sliding in guide rails, properly situated parallel to the vertical place of the mirror and to the horizontal surface at the height of the first ends of the first level and accordingly first ends of the second lever . Elements of both pairs of levers are connected with a drive assembly and on-off assembly.

The purpose of the invention is development of a design of a guide enabling sliding and protracting of a surface from base surface along any path, with ability to situate protracted surfaces at various angles, in any position with respect to the base surface.

The essence of the invention is the design of the scissor guide enabling sliding and protracting of surface elements at any angle, along any path, and situation of surfaces of these elements i any position with respect to the base wall surface.

The scissor guide according to the invention is comprised of two arms movably connected with each other, crossing at any angle. The ends of the arms on one side are attached from the bottom to the movable element, while their opposite ends are attached to the base wall surface. On one side there are movable fixtures, and on the opposite side linear guide rails. The ends of the crossing arms on the opposite side of movable fixtures are preferably provided with slides, and these in turn are placed in linear guide rails, attached below the movable fixtures, both to the back surface of the sliding elements and to the base wall.

The crossing arms may be made of closed sections or open sections, including perforated sections or provided with a groove along the entire length, enabling connection of these arms at any point.

Possibility of connecting the crossing arms at any point enables obtaining of any angle of gape between them and any related geometry of sliding and protraction. Situation of the coupling point in the middle of the arm length ensures motion of the sliding element parallel to the surface of the base wall. In case of need for situation of the surface of the sliding element at an angle, the inclination angle of the sliding surface is adjusted by changing of position of the coupling point of the crossing arms. The inclination angle of the sliding element surface and the outline of the path to be taken by this sliding may be freely adjusted by selecting the location of the coupler in the crossing arms and selection of appropriate type of rotating fixtures. Depending on the needs and operating possibilities it is possible to apply rotating or rotating- articulated fixtures. Application is also anticipated of a non-rotating fixture in the form of an angle bar enabling inclination of the arm only in one direction. Applicable linear guide rails include such with ball, roller, friction, sliding etc. slide.

In a situation of large loads following from heavy weight of sliding elements, application of several scissor guides simultaneously is provided for, working together as an assembly.

The solution according to the invention is characterized by simplicity of execution from universally available materials, and ease of operation. The scissor guide, owing to its design, ensures stable fixation and safe movement of sliding planes.

The subject of the invention is clarified in the execution example on the enclosed drawing, where fig.1 - presents the scissor guide in a general side view, fig.2 - shows the rotating fixture connected with s crossing arm in a general view, fig. 3 - shows a fixing detail of a crossing arm in the linear guide, fig. 4 - the guide in general view, where the surface of the element sliding with respect to the base wall surface is inclined aslant, fig. 5 - shows the guide where both the sliding and the base surface are facing aslant.

The scissor guide according to the invention is built of movably joined, crossing arms 1. The ends of the arms 1 on one side are attached to the. back surface 2 of the sliding element 3, and on the opposite side to the base wall 4. The surface of the sliding element having the form of a mirror 3 is situated parallel to the base wall 4. The ends 1A of the crossing arms 1 are joined with the back surface 2 of the sliding mirror 3 and with the base wall 4 by means of rotating fixtures 5. The ends IB of the crossing arms 1 are provided with slides 6 located in linear guides 7, attached to the back surface 2 of the sliding element 3 and to the base wall 4, below rotating fixtures 5. The crossing arms 1 are connected with each other by means of a connector in the form of screw 8.
