Definitions

• the invention relates to a device for adjusting the height and / or inclination of the table top of a table according to the preamble of claim 1.
• Worktop is pivotally mounted on a frame in the area of a first longitudinal edge about a horizontal axis and lies on essentially vertical supports in the area of a second longitudinal edge.
• the supports are height-adjustable and lockable on the frame.
• At least one support is pivotally arranged on the worktop and is provided with a link guide which has locking receptacles for a guide bolt fixed to the frame. The support can be locked with the help of a releasable locking mechanism.
• the known device is complicated in structure and cumbersome to use.
• the object of the present invention is to provide a simple and safe device for height and / or inclination adjustment of a table, which is easy to use without risk of injury.
• the invention provides a device for adjusting the height and inclination of the table top, which is relatively simple to manufacture and is simple and safe to operate. It is no longer necessary to operate any levers and mechanisms below or in the area of the adjusting device.
• the invention will be explained below with reference to the accompanying drawing, in which an embodiment is shown.
• FIG. 1 is a side view of a table with a device for height and / or inclination adjustment of the table top,
• Fig. 2 is a rear view of the table of Fig. 1, Fig. 3a, b + c different views of a component of the
• the drawing shows a table 2 with a table frame 6 and a table top 8 and with a device 10 for Height and / or inclination adjustment of the table top 8.
• the device 10 comprises an outer tube 14, which is attached to the table frame 6 by means of a swivel joint 12 and has a round or oval cross-section, in which a rod 16, preferably made of solid material and a circular cross-section, can be displaced and rotated.
• a rod 16 preferably made of solid material and a circular cross-section
• the rod 16 is attached to the table top 8 by means of a ball joint 18 and by means of a screwed one
• the outer tube 14 has three spaced oval holes 20, 22 and 24 arranged one above the other.
• the holes can also be round or rectangular.
• the rod 16 has in the lower area in a recess 26 a pivoting block 30 which is biased by means of a compression spring 28 into a pivoted-out basic position for latching into one of the oval holes 20, 22 and 24 of the outer tube. In the basic position, the locking block 30 projects with its free end 32 from the surface of the rod.
• the rod 16 also has in its surface a first straight guide groove 36 which is formed in the longitudinal direction of the rod and in which a side on the side opposite the oval holes is firmly attached in the outer tube 14 and into the
• Guide pin 38 projecting inside the outer tube is slidably guided.
• a second guide groove 40 running parallel to it branches off from the first guide groove 36 in the upper rod region.
• the first guide groove 36 bends in the lower region of the rod towards the second guide groove 40 and is connected to its lower end.
• the first guide groove 36 opens at the upper end 34 of the rod below the ball joint 18;
• the guide pin 38 of the outer tube 14 can then be pre-assembled and easily inserted into the guide groove during assembly.
• the guide groove 36 can also be closed at the top; in this case the pen retrofitted in the outer tube.
• the second guide groove 40 is formed on the side of the rod 16 diagonally opposite the locking block 30, while the first guide groove 36 is arranged laterally offset from it. This arrangement ensures that the
• Locking block 30 can only snap into one of the oval holes 20, 22, 24 when the guide pin 38 of the outer tube 14 slides in the second guide groove 40.
• the first guide groove 36 serves to reset the table top of the table.
• the device for height and / or inclination adjustment works as follows: In the 0 ° position, ie in the lower horizontal position of the table top 8, the guide pin 38 of the outer tube 14 is located in the lower end of the first or second guide groove, see. 5a and 6a. When the table top 8 is pivoted upward or raised, the guide pin 38 slides upward in the second guide groove 40; the locking block 30 snaps into the oval holes 20, 22 and 24 one after the other, and the table top 8 can be brought into the desired height or inclination position.
• the table top 8 is pivoted or lifted upwards until the guide pin 38 from the second guide groove 40 into the first guide groove 36 slides.
• the guide pin 38 automatically slides down along the first guide groove 36 into the lower end of the second guide groove 40.
• the first guide groove 36 thus serves to return the table top to the changeover or lowest position.
• the locking block 30 slides next to the oval holes 20 to 24 on the inner surface of the outer tube and is automatically rotated in the 0 ° position into the path of the oval holes, which coincides with the second guide groove 40.
• the guide pin 38 slides automatically upwards in the second guide groove 40, so that the rest area 30 can snap into the oval hole 20, 22 or 24 assigned to the desired table inclination or the desired table height. If only one height adjustment is provided, the outer tube 14 can also be firmly connected to the table frame.
