Description

[0001] The invention relates to a sliding block for fastening objects to a workbench having a table top with at least one groove which is T-shaped in cross section and / or cross-shaped, so that the groove has shoulders.

[0002] T-nuts are used to connect and fasten objects on workbenches with tabletops with T-shaped grooves and / or cross-shaped grooves.

[0003] DE 23 29 640 A1 discloses a T-slot nut for securing parts in a T-shaped groove. The nut consists of an elongated polygon with a hexagonal outline. The T-slot nut is designed to be inserted into the groove from above. It pivots within the groove for securement.

[0004] German patent document DE 40 18 100 A1 discloses a profile strip with a longitudinal groove. A sharp-edged T-slot nut can be placed in this groove. The T-slot nut is designed so that it can be easily inserted through the slot into the groove. It can be provided with a piece of foam to prevent slipping when vertically positioned.

[0005] The publication DE 91 05 646 U1 contains a T-slot nut with a substantially parallelogram-shaped base. The base of the T-slot nut facing the undercut surface of the profile groove is provided with a profile running transversely to its two shorter edges. This prevents the T-slot nut from slipping in the profile groove when not under load.

[0006] The invention defined in claim 1 is based on the object of providing a sliding block with large contact surfaces.

[0007] This problem is solved by the features listed in claim 1.

[0008] The T-slot nut for fastening objects to a workbench with a table top having at least one T-shaped groove and / or cross-shaped groove in cross section, so that the groove has shoulders, is characterized in particular by large contact surfaces.

[0009] The T-slot nut is a base body with a raised area. The cross-sections of the base body and the raised area each have a rhomboid shape. The width of the base body is smaller than the width of the spaced-apart side walls of the groove and greater than the distance between the shoulders of the groove. The height of the base body is smaller than the height of the side walls of the groove. The width of the raised area is smaller than the distance between the shoulders of the groove, so that the width of the raised area is smaller than the width of the base body and the base body projects beyond the raised area on both sides. The height of the raised area is smaller than the height of the side walls of the spaced-apart side surfaces of the shoulders of the groove. The base body and the raised area are one piece. The T-slot nut also has at least one connecting element.

[0010] The cross-sections of the base body and the raised portion are advantageously each shaped like a rhomboid, and thus like a parallelogram. The width of the raised portion is smaller than the width of the base body, so the base body projects beyond the raised portion on both sides in the longitudinal direction of the T-slot nut. The resulting surfaces and the adjacent side surfaces of the raised portion serve as contact surfaces for the T-slot nut in the groove. Its rhomboid shape allows the T-slot nut to be easily inserted and moved into the groove. When connecting and fastening the object, the raised contact surfaces ensure a better fit for the T-slot nut in the groove. Furthermore, greater clamping forces can be achieved.

[0011] Advantageous refinements of the invention are set forth in the following developments and embodiments. These can develop the T-slot nut for fastening objects to a workbench with a tabletop having at least one T-shaped and / or cross-shaped groove in cross section, such that the groove has shoulders, individually or in combination.

[0012] In a further development, the connecting element can be a bore.

[0013] In a further development, the connecting element can be a hole with an internal thread. This allows an object with a bolt with an external thread to be easily connected and secured to the T-slot nut and thus to the workbench tabletop.

[0014] In a further development, the connecting element is advantageously positioned centrally in the T-slot nut. This ensures that the forces occurring during use of the T-slot nut are evenly distributed.

[0015] In one embodiment, the surfaces of the base body projecting beyond the elevation and the side surfaces of the elevation arranged at an angle thereto enclose right angles.

[0016] The width of the elevation is smaller than the width of the base body, so that the T-slot nut advantageously has shoulders.

[0017] In one embodiment, the lengths of the opposing sides of the T-slot nut can be equal. Furthermore, the lengths of the sides with shoulders of the T-slot nut are smaller than the lengths of the sides without shoulders.

[0018] At least the sharp corners of the T-slot nut can be rounded in a further development. The T-slot nut thus designed is easier and simpler to insert into the groove and move within it.

[0019] An embodiment of the invention is shown in principle in the drawings and is described in more detail below.

[0020] They show: Fig. 1 a slotted nut in a T-shaped groove, Fig. 2 a sliding block in a top view and Fig. 3 a sliding block in a side view.

[0021] A sliding block 5 for fastening objects to a workbench with a table top 1 having at least one groove 2 with a T-shaped cross section, so that the groove 2 has shoulders 3, essentially has a base body 6 with an elevation 7.

[0022] The Fig. 1 shows a sliding block 5 in a T-shaped groove 2 in a basic plan view.

[0023] The sliding block 5 has the base body 6 with the elevation 7. The cross-sections of the base body 6 and the elevation 7 each have a rhomboid shape. The width of the base body 6 is smaller than the width of the spaced-apart side walls 4 of the groove 2 and greater than the distance between the shoulders 3 of the groove 2. The height of the base body 6 is smaller than the heights of the side walls 4 of the groove 2. This means that the base body 6 can be placed in the groove 2 and moved therein. The width of the elevation 7 is smaller than the distance between the shoulders 3 of the groove 2, so that the width of the elevation 7 is smaller than the width of the base body 6 and thus the base body 6 projects beyond the elevation 7 on both sides. The height of the elevation 7 is smaller than the height of the side walls 8 of the spaced-apart side surfaces of the shoulders 3 of the groove 2. The width of the elevation 7 is smaller than the width of the base body 6, so that the sliding block 5 has shoulders 9.The base body 6 and the elevation 7 are one piece.

[0024] The Fig. 2 shows a sliding block 5 in a basic plan view.

[0025] The cross-sections of the base body 6 and the raised portion 7 each have the shape of a rhomboid. The width of the raised portion 7 is smaller than the width of the base body 6, so that the base body 6 projects beyond the raised portion 7 on both sides in the longitudinal direction of the T-slot nut 5. The T-slot nut 5 has a connecting element in the center. The connecting element can, in particular, be a bore 10 with an internal thread.

[0026] The Fig. 3 shows a sliding block 5 in a basic side view.

[0027] The lengths of the opposite sides of the T-slot nut 5 are equal. The lengths of the sides with shoulders 9 of the T-slot nut 5 are smaller than the lengths of the sides without shoulders. QUOTES CONTAINED IN THE DESCRIPTION
