Description: Showroom furniture construction system. The invention pertains to a variable showroom furniture construction system and more in particular to a wooden (dis)mountable, variable showroom furniture construction system that in mounted condition consists at least of vertical stands and a number of, in mounted condition, horizontal, in height adjustable fitted place-trays, which on their outer ends are supported by detachable supports attached to the stand. Until the present a number of different such like construction systems have been proposed. These on the one hand have the disadvantage that for mounting use is made of, from the outside clearly visible, esthetically unsightly metal parts and/or series of bore holes, as a result of which the mounted system is un- or less suited to be applied for a true furniture function . On the other hand such systems are comprised of components connected to each other thus that an insufficient sturdy construction is achieved, which more in particular in the long run proves not to endure the normally occurring heavy stress, or else a sufficiently sturdy mounted system can be realized only by means of rather complicated and elaborate mounting. Subsequently there is still demand for a simple and financially attractive manner of manufacture of a predominantly wooden showroom furniture construction system which is easy to (dis) mount, that is truly acceptable from an esthetic point of view as a piece of furniture thanks tothe lack of visible unsightly metal parts and/or series of bore holes. Purpose of the invention is therefore to provide a financially attractive and easy to (dis)mount, variable showroom furniture construction system, that moreover meets the demand described in the above. Now found is such a predominantly wooden showroom furniture construction system, characterised by an in mounted condition vertical stand, consisting of two vertical profile beams (1) , which are connected on the top and bottom end by cross beams (2) , whereby the two vertical profile beams (1) are, on the inward facing side, provided with an in longitudinal direction made groove (3), in the bottom of which at desired distances a number of preferably round pin holes (4) have been made, in which the pins (5) of distance blocks (6) fit, whereby each time on two opposite distance blocks placed at the same height, rests a place-tray supporting beam (7) , on which a place-tray (8) rests with one end, whereby the place-tray supporting beam on this outer end, is, on the surface facing the place-tray which rests upon it, provided with recessed pin holes (9) or protruding pins (10) , while in the surface of the place-tray on the place of these pin holes (9) or protruding pins (10) respectively corresponding pins (10) or pin holes (9) are found, while the other outer end of the pertaining place-tray rests on a place-tray support (11) , which is removably detached to a, against one of the longitudinal sides of the place-tray situated compound supporting beam (12), consisting of two parallel beams (121) r on the upper and lower side connected by cross beams (122) , whereby protruding pins (111) fixed on both sides of the, placed between two beams (121) situated place-tray support (11), are found on the end of one set of parallel, opposite, on the inner surfaces of the two beams (121) recessed grooves (123), placed at regular distance and alternating, starting from both longitudinal sides of a beam (121) and sloping downwards across only a part of the width of the inner surface of the beam, while on the end of an opposite set of successive lower grooves (123) the protruding pins (131) , attached to both sides of a locking block (13) are found, whereby the locking block (13) is found in a recessed area (112) on the underside of the place- tray support (11) . Design forms of such a showroom furniture construction system are illustrated in Figures 1-4. The width of the groove (3) in the inner side of the vertical profile beam of the stand must as closely as possible have the same dimensions as the width of the distance blocks (6) in order to restrict the space between these blocks and the groove walls as much as possible, giving a mounted show¬ room furniture construction system maximum sturdiness. The showroom furniture construction system can comprise both design forms in which on the underside on one of the outer ends of the place-tray, pro¬ truding pins (10) have been made in suitable places to fit the recesses (9) in the upper surface of the place-tray support, as well as design forms in which the underside on one outer end of the place-tray is provided with recesses (9) in which protruding pins (10) , fixed where suitable on the upper side of the place-tray support, fit. According to a preferable design form of the showroom furniture construction system subsequent the invention, the aforementioned pin holes (9) in the place- tray supporting beam are made in the upper surface of a bulge found in longitudinal direction, of which the upper surface can be found in the pro¬ duced part of the upper surface of the centre part of the place-tray sup¬ porting beam or lower, and preferably that much lower that in mounted condition the upper side of the place-trays and the upper surface of the central part of the place-tray supporting beam are in each others extension. Such a design form is illustrated in Fig. 3 and 4. The difference in height between the upper surface of the bulge.and upper surface of the central part of the place-tray supporting beam (7) shall therefore preferably be the same as the thickness of the place-tray. The intended bulge can for instance be achieved simply by putting a parallel beam in the longitudinal direction against the side wall (s) of a place-tray supporting beam, at the desired height, depending on the thick¬ ness of the applied place trays. The in the distance blocks (6) and the on the under side of each place-tray (8) at the place of the recessed pin holes (9) in the place-tray supporting beam placed pins (5) and (10) , can in principle be manufactured from different suitable materials with sufficient strength and flexural strength, such as specially for that purpose selected plastics or metals. The pins shall preferably be made of metal. The protruding pins shall preferably consist of cylindrical bodies with a diameter of 3-8 mm and there within preferably of 4-6 mm, and with a length of 6-15 mm and there within preferably of 8-10 mm. The pin holes (4) and (9) preferably have the same shape and dimensions so that these can be made in one standard operation, preferably by boring to a depth of 7-16 mm and there within, more preferably of 9-11 mm. The distance blocks (6) can be made of different suitable, shape retaining materials with low thermic expansion, such as certain plastics or wood. Preferably these distance blocks are made in wood and fitted with a metal pin or if, forming one unit, a formed piece of a suitable plastic. For a maximum strength of the assembled showroom furniture construction system subsequent the invention, the space between the walls of the pins (5) and (1) and the corresponding pin holes (4) and (9) in the wooden parts, must be as small as possible. The mutual distance between the parallel grooves in the inside surfaces of the two component vertical beams (121), each time from one of the longitudinal sides of the beams (121) , can in principle vary over a large area, depending on the specific application, or else the nature of the products to be displayed, but shall be at least 10 cm, while the length of the downward sloping grooves can vary from 10-20 mm. The difference in height and the mutual distance of the respective end points of two successive grooves (123) , beginning on both longitudinal sides of a beam (121) and that between the pins on the place-tray support and the pins on the in the recess (112) fitted locking block (13), must by and large be the s me. The recess (112) on the under side of the place-tray support (11) in which the locking block (13) fits shall preferably be rectangular in shape, with dimensions of the respective width and depth varying from 10-20 mm, depending on the desired dimensions for the locking block (13) , whereby the width is preferably greater than the depth. The protruding pins (111) and on both sides of the place-tray support (111 and on both sides of the locking block (13) shall preferably consist of a cylindrical rod with a length of 3-10 mm and a diameter of at least 6 mm. The pins shall preferably be manufactured of a for that purpose chosen metal, with sufficient strength and flexural resistance. According to a preferable design form of the showroom furniture construction system, the place-trays are made thus that their longitudinal axis is at an angle of 50-70 degrees to the plane of the two vertical profile beams (1) of the stand on the pertaining outer end of the place-tray. This angle will preferably be approx. 60 degrees in connection with the claer visibility of the objects on display. On the outer end resting on the place-tray support (11) the place-trays have a preferably rectangular shape and can have dimensions, which can vary over a considerable distance, depending on their special designation. In general the width shall vary from 20-40 cm and preferably from 30-30 cm, while the usually applied length shall lie between 70-140 cm and preferably between 90-110 cm. According to a further preferable design form the component vertical supporting beam (12) is fitted on the under side with a fixed lower beam (14) which is oriented perpendicular to the vertical supporting beam (12) and in the same direction as that of the place-tray supports (11) there above. More preferably the outer end of the lower beam (14) that is attached to the vertical supporting beam (12) also forms a cross beam (122) between the vertical parallel beams (121). The height of the lower beam (14) ia preferably 10-15 cm. Preferably the lowest place-tray is placed on the upper surface of the lower beam (14) . For the purpose of a maximum strength of the mounted showroom furniture system, the space between the walls of the recessed space (112) and the walls of the locking block (13) is as small as possible, on the other hand it should leave sufficient space for the easy insertion and removal of the block. The locking blocks (13) can also be manufactured of different suitable, form retaining materials with low thermic expansion, such as certain selected suitable plastics or wood. Preferably the locking blocks are made of wood, whereby the fibre direction of the wood must be perpendicular to the wood fibre direction of the place-tray support (11) and run in the direction of the short side planes of the locking lock. It will be evident that the component elements of the showroom furniture construction system according to the invention, can very simply and quickly be manufactured, and in large series, and therefore in a financially attractive manner with the aid of suitable equipment for such purposes, while for the . showroom furniture construction system under consideration the following other advantages can be combined: a. from the outside only wood is visible on the mounted showcase system, thus offering an important advantage from an esthetical point of view; b. as a result of the applied manner of .assembly, which is relatively fast and easy, a sturdy construction is realized; c. thanks to easy mounting and dismounting the arrangement of the desired showroom furniture construction system is simple to alter according to wish, depending on the ever changing user requirements; d. because of the great variation possibilities with regard to the dimensions of the component parts, the showroom furniture construction system is greatly variable in height and width. The invention also pertains to the characteristic separate parts of the showroom furniture construction system described above, and more in particular the stands, fitted with the vertical profile beams (1), the distance blocks (6), the place-tray support beams (7) , the place-trays (8) with pins (10) , the place- tray support (11) , the vertical component supporting beam (12) and the locking blocks (13) . It will be evident that these parts and more in particular the stand, the place-trays (8) , place-tray support beams (7) and place-tray supports (11) and the vertical component support beams (12) can be manufactured from a great variety of common furniture woods or combinations thereof, whereby these parts can be veneered or varnished with colour varnish or with wood grain pattern accentuated varnish.
