Definitions

  • the invention relates to a table according to the preamble of claim 1.
  • a table is known from DE-A-32 11 940.
  • a similar table is previously known from DE-OS 38 90 499, here too a parallelogram handlebar arrangement is used to adjust the height of the table top, with a locking or braking device being provided to fix the selected height setting. An adjustment of the inclination of the table top is not provided here.
  • the invention has for its object to provide a table of the type mentioned, which is provided with a simple, reliable and quick-to-use locking system with a simple structure and inexpensive to manufacture.
  • the table according to the invention is characterized by a number of considerable advantages. Since only one locking device is used, the operator can position the table top in the desired manner, i.e. adjust in height and tilt. As soon as this desired position is reached, the operator can fix the table top in position by means of a single handle by actuating the one locking device.
  • the locking device according to the invention is infinitely adjustable, since the operator can then bring the tabletop into any position and lock it in this position when the locking device is released.
  • the locking device comprises a horizontal rod, at one end of which an eccentric is mounted for clamping and which engages through a tilting device mounted on the table top and a height adjustment device mounted on the base frame.
  • This embodiment is particularly advantageous because it is clamped by an eccentric, which is easy and reliable to operate and enables a high clamping force to be applied.
  • the use of the horizontal bar enables the parallelogram handlebar arrangement to be designed twice, so that the entire table is highly stable and tipping-proof. Even with a longer length of the horizontal rod, secure locking and clamping can be achieved using a single eccentric device.
  • the height adjustment device has at least two parallelogram links, namely an upper and a lower one, which are pivotably supported with one end each on a vertical column of the base frame and on a vertical support. It is understood that two vertical columns can be provided, on each of which a pair of parallelogram links are mounted. As a result, two vertical supports that are parallel to each other can also be used to increase the tilt resistance of the table. The upper area of the vertical support supports the table top. In order to achieve a locking of the height adjustability, one end of an intermediate link is pivotally mounted on the upper parallelogram link, the other end of which is penetrated by the horizontal rod in the area of the locking device. When the Parallelogram link arrangement thus results in a pivoting or tilting of the intermediate link, so that it can be clamped in different positions relative to the horizontal rod.
  • the intermediate link is provided with an elongated hole for the passage of the horizontal rod.
  • the tilting device is preferably designed in such a way that it has at least one support which extends perpendicular to the table top and is fastened to the table top and which is pivotably mounted about the horizontal axis at the upper end of the vertical support.
  • the carrier is provided with an arcuate slot, the center of which forms the horizontal axis.
  • the horizontal bar extends through the arcuate slot. In this way, the respective tilting position of the table top can be locked by the horizontal rod sliding in the arcuate slot.
  • an adjustable abutment is provided at the free end of the horizontal rod, for example in the form of a nut screwed onto the horizontal rod.
  • the eccentric can preferably be actuated by means of a hand lever, which, in a favorable further development, can be designed to be variable in length. This makes it possible to insert the hand lever after locking the table top under it so that the hand lever does not interfere and so that unintentional movements of the hand lever are avoided.
  • the tilting device and the height adjustment device are each provided with a device for weight compensation, for example a spring device or the like.
  • the table comprises a base frame 1, to which two vertical columns 8 are attached, which are connected by means of cross members for reasons of stiffening.
  • the base frame as usual, has two horizontal struts, but it can be designed in any other way.
  • two parallelogram links 6, 7 parallel to one another are pivotally mounted, at the free end of which a vertical support 9 is pivotally mounted.
  • a device 16 for weight compensation serves for corresponding support or suspension of the upper link 6.
  • an intermediate link 10 is pivotally mounted on an articulation point 20, which is essentially parallel to the vertical support 9 extends.
  • a horizontal axis 2 is provided, around which a table top 3 can be tilted.
  • a carrier 12 is used for this purpose, which, as can be seen in particular from FIG. 7, extends at right angles to the table top 3.
  • a device 17, for example in the form of a spring, serves to cushion and absorb the weight of the table top 3 when it is tilted.
  • a horizontal rod 4 is arranged, which extends freely through the vertical support 9 (see Fig. 7).
  • the horizontal rod 4 also extends through an elongated hole 11, which is formed in the vertical direction at the end region of the intermediate link 10.
  • the horizontal rod 4 extends through an arcuate slot 13 of the carrier 12. The horizontal rod 4 thus does not hinder the pivoting of the table top 3 nor the horizontal adjustment by means of the parallelogram linkage, since the arcuate slot 13 also allows the carrier 12 to move, as is the case Elongated hole 11 allows movement of the intermediate link 10.
  • Fig. 7 shows that an abutment 14 is provided at one end of the horizontal rod 4, which is designed in the form of a nut and thus offers an adjustment option.
  • an eccentric 5 is provided, which can be brought into different positions by rotating a hand lever 15, which is provided with a handle 21, so that a clamping between the vertical supports 9, the supports 12 and the Intermediate link 10 occurs, which causes a locking or braking of the table top 3 in any position.
  • 5 and 6 show in comparison different positions of the eccentric 5, from which the possible clamping path 22 results.
  • Fig. 4 shows that two eccentrics 5 are provided in parallel, which are designed in the form of ball bearings. This results in favorable force and friction conditions.
  • the inner rings of the two ball bearings are placed on a tube 23 in which the actual hand lever 15 is slidably mounted. This makes it possible to insert the hand lever under the table top 3 when not in use.
  • the tube 23 In order to enable the tube 23 to be rotated, it has a slot 24 at its free end, in which a cross pin 25 of the hand lever 15 can be inserted.
  • the bolt 25 and the slot 24 thus form a coupling.
  • the front end of the hand lever 15 is received and supported by a holding plate 26.
  • 10 tabs 27 are provided parallel to the intermediate link, which also have an elongated hole and are mounted on the intermediate link 10. Such tabs can also, as shown in FIG. 7, be attached in the interior of the intermediate link 10. Together with washers 28, they serve to increase the friction, whereby the washers 28, as can also be seen in FIG. 7, can each be arranged between the individual elements.
  • the operator first pulls the hand lever 15 outwards by means of the handle 21, so that the bolt 25 engages in the slot 24.
  • a rotation of the tube 23 is possible, through which the eccentric 5 is rotated into the released position.
  • the table top 3 both in height and in inclination, since the horizontal rod 4 is freely displaceable in the elongated hole 11 or the arcuate slot 13.
  • the operator rotates the handle 21 again, whereby the eccentric 5 is brought into its locked position. If the clamping force is not sufficient, an appropriate compensation can be created by adjusting the abutment 14. The operator can now push the hand lever 15 under the table top 3 without the clamping process being affected thereby.
