The object of the invention is a table for sewing machines, both for basic machines and for specialised machines.

A table for sewing machines shown in the description of utility model No. Ru 62774 is known. This table is composed of a frame to which a tabletop is mounted. The frame is composed of two stands releasably connected by two horizontal beams. The stand is composed of a base beam, the ends of which are based on pads. On the base beam, a pillar beam is mounted, and a tabletop bracket is mounted thereon. The base beams are connected to each other with one of the horizontal beams, and a foot treadle is mounted thereto. The tabletop bracket has at least three holes, and the pillar beam has, at its upper end, two elongated holes located along the beam, and in the said holes, coupling bolts are mounted, and the pad has a shielding flange with catches.

Also, a foldable structural element, especially a furniture structural member, shown in patent description EP 1508286, is known. This element comprises at least two planar sub-elements. The sub-elements have first surfaces and second surfaces and have at least one connecting edge and outside edges. The sub-elements being pivotably linked to each other along the connecting edges. At least one of the surfaces of one sub-element lying opposite the surface of the second sub-element. Fixing means which connect an outside edge of one of the sub-elements with another sub-element are provided. The outside edge of one of the sub-elements is connected with one of the surfaces of further sub-element. The outside edge of one of the sub- elements is connected with the outside edge of further sub-element. The fixing means is an adhesive. The adhesive is a synthetic adhesive, especially a hot melt type adhesive. The fixing means is in the form of an adhesive tape. The fixing means is in the form of a bracket. The sewing machine table of the invention consists of a tabletop in the form of a plate with an aperture for the sewing machine, where the tabletop is placed on the frame. The table is characterised in that the tabletop has, in its side walls, notches, in which profile bars are pressed, preferably channel bars. The height of the profile bar is lower than or equal to half the thickness of the tabletop. The pressed profile bar is arranged symmetrically in relation to the thickness of the tabletop. The pressed profile bar is additionally fixed with screws to the tabletop. The tabletop has a thickness of at least 39mm. The heads of the rails attached to the sides of the additional elements are seated in the pressed profile bars. The rails have their bases pressed in the notches in the side walls of the additional elements. The rails are pressed in the notches in the side walls of the additional elements at least to a depth of the thickness of the rail base. The profile bars are pressed in the side wall of the tabletop at least to a depth equal to the width of the channel bar. The pressed rail is additionally fixed with screws to the side of the additional element.

The sewing machine table of the invention, is characterised by simple construction and at the same time by unusual functionality as its construction allows shaping of any table surface, adapting it to current needs related to the use of the sewing machine. Surprisingly, it appeared that clamping connection in wooden or wood-based elements is significantly more durable than bolt connections. Therefore, this connection is a main connection which transmits forces occurring in this connection, and the used bolt elements constitute only an additional protection. In case of sewing small pieces, the existing table is sufficient and there is not any need to enlarge it. On the other hand, when changing the product range to sewing larger pieces, it would be necessary to replace the table with a larger one. Instead, in the present case, additional elements, which increase the size of the table, are added. At the same time, adding additional elements does not pose any difficulties because it is easy and quick, it occurs by inserting the rail with an additional element into the channel bar, pressed to the side of the table. Further, when sewing small pieces, it is necessary to refer to the design of the product sewn. With this table construction, its extension is possible by adjusting its surface to the size of the design.

The sewing machine table of the invention, is explained in details in the embodiment and in the drawing, in which Fig. 1 shows the table in a side view with the tabletop without additional elements, Fig. 2 is a top view of the tabletop with additional elements, Fig. 3 is a cross section through the connection of the tabletop with an additional element, the additional element being spaced from the tabletop.

As shown in Fig. 1 - Fig. 3, the sewing machine table of the invention consists of a tabletop 1 in the form of a plate with an aperture 2 for the sewing machine. The tabletop 1 is placed on a frame. The frame is composed of two stands connected by horizontal beams. Each stand is composed of a base beam 3, the ends of which are based on pads 4. On the base beam 3, a pillar beam 5 is mounted, and on the latter, a bracket 6 of the tabletop 1 is mounted. The bracket 6 is connected to the pillar beam 5 by means of regulatory bolts 7, whereby it is possible to adjust the level and inclination of the tabletop 1. The tabletop 1 has, in the side walls, notches in which profile bars, in the form of channel bars 8, are pressed. Height H of the channel bar 8 is equal to half the thickness G of the tabletop 1. The pressed channel bar 8 is arranged symmetrically in relation to the thickness G of the tabletop 1. The pressed channel bar 8 is additionally fixed with screws 9 to the tabletop 1. This connection is made in a known manner, thereby the screws 9 are only indicated axially. The tabletop 1 has a thickness of 40mm. In order to extend the tabletop 1 of the sewing machine table, additional elements 10, 11 and 12 are made. In the sides of the additional elements 10, 11 and 12, notches are formed, the size of these notches being varied according to the position of this element and its connection. The additional element 10 has its longer side in contact with the tabletop 1 , and in this side, a notch for a rail 13 base is formed. On the other hand, the connection of the shorter side of the additional element 10 with the side of the additional element 11 is also the connection shown in Fig. 3, however, a notch for the channel bar 8 is formed in the shorter side of the additional element 10. The connection of the additional elements 11 and 12 is made likewise, where in the shorter side of the additional element 12, a notch for the channel bar 8 is formed. The rails 13 are pressed into the sides of the additional elements 10, 11 and 12 to a depth F equal to the thickness of the rail 13 base. The channel bars 8 are pressed in the side wall of the tabletop 1 to a depth equal to the width A of the channel bar 8. The pressed rail 13 is additionally mounted with screws 14 to the side of the additional element 10 or 11 , or 13, in a known manner, thereby the screws are only indicated axially.
