Description

The invention relates to a table with a movable worktop on a legged table frame, preferably made of solid wood according to the Preamble of claim 1.

It is basically known to be the flexible guide a table top through below the table top attached burr strips along with on the side Table support or the table legs arranged To ensure running bars. Laterally the The table tops are running rails known for example from GB-PS 377 598. By a device of this type is made, for example a table top on a table frame slidable. It is also known in principle Worktops of tables for ergonomic reasons relative to the support plane of the worktop tend. Especially drawing tables made of metal or Nowadays plastics have Folding mechanisms that tilt a certain angle e.g. by folding up the worktop and Allow locking with locking elements. Such devices are in particular from US-PS 1,560,131 and U.S. Patent 2,027,609. In the However, the device according to US Pat. No. 1,560,131 is Sliding mechanism designed relatively expensive and therefore requires a lot of space in the Countertop area. The folding mechanism according to the US-PS 2 027 609, however, requires a complex designed linkage

For tilting or folding devices according to the state of the However, technology is at risk of failure Elements evident, what is causal for the damage or the destruction of the tilting or folding mechanism for particularly heavy solid worktops or Tables, e.g. can be made of solid wood.

From DE-GM 90 14 828 is a table with movable worktop known from Solid wood is made. In doing so Tread bar assemblies used, although a Adjust the worktop in vertical and allow horizontal direction, however this track bar assembly claims a relative great depth of the table. This contradicts that Trend towards less deep tables, especially office and Desks. In addition, the Movement sequence for adjusting the worktop through several steps, namely pulling forward, tilting marked and pushed back.

From DE-C- 477 711 a generic table with a movable worktop is known, which rests in a horizontal rear part that is part of the Total worktop of the table is. The worktop is swiveled also around a pivot point in the rear area, so that a Locking device must be attached to lifting the Worktop in its angled position by pressing down the edge of the table to prevent. After all, the worktop cannot be pushed at the same time and turning can be adjusted in their inclination.

It is therefore an object of the present invention a table of the type mentioned at the beginning with a movable worktop, preferably to create solid wood, the Worktop in certain inclinations and in the Horizontal relative to the support plane on the Table frame at the same time easier and energy-saving handling can be fixed. Thereby supposed to shorten the depth of the table below Creation of ergonomically favorable working conditions for the user. Furthermore the construction should be as simple and be economically producible.

According to the invention the task is characterized by the characteristic features of Claim 1 solved.

The longitudinal guide arrangement consists of a Longitudinal groove-bolt connection, each on two opposite lateral front edges of the Worktop between this and the table frame is arranged, the bolt being the fulcrum forms and the bolt slides in the longitudinal groove. On the underside of the worktop on the other opposite end faces is the Guide rail assembly formed, the wedge shape itself in relation to the horizontal from the user side extended out to the rear. At least one crossbar is provided on the table frame with a each free wedge surface of the Guide bar arrangement in contact relationship can be brought, the sliding movement on the Crossbar exercises.

In further training, the longitudinal groove Longitudinal groove-bolt connection in each case near the user Area of the front of the countertop and the in the longitudinal groove in the front of the Worktop opposite table frame arranged. The longitudinal groove runs about 1/3 the length of the front of the worktop.

In another embodiment of the invention the longitudinal guide arrangement consists of a Longitudinal groove-bolt connection in their Direction of movement parallel to the two opposite lateral front edges of the Worktop between this and the table frame on the respective underside of the worktop and the table frame in the immediate vicinity of the Front edges are arranged.

Each longitudinal groove-bolt connection consists of opposite guide elements, being a Guide the longitudinal groove and the other corresponding guide element the bolt having. In a variant, the longitudinal groove containing guide element on the worktop and the guide element containing the bolt on Table frame can be arranged. In another Variant can contain the longitudinal groove Guide element on the table frame and the bolt containing guide element on the worktop be arranged.

The free wedge surface of the guide bar assembly can be a transverse groove for the positive reception of the Cross bar in the horizontal and angled Have the position of the worktop. In preferred Execution runs the bottom surface of the transverse groove angled with respect to their side faces to one to form acute angles to the horizontal. Of the acute angle of the bottom surface corresponds to the transverse groove about the angle of inclination of the worktop in the angled position.

The angle of inclination of the worktop in the angled position is expedient about 5 to 15 °, preferably 8 °.

After all, at least one of the Guide bar arrangements in the table frame protruding and with the table frame in plant have feasible securing part that the Worktop in its angled position fixed.

With this solution according to the invention, a simple, with a single movement marked adjustment of the worktop be carried out. It is irrelevant whether the Worktop has a large weight because of the free wedge surfaces of the guide bar assembly slide the crossbar until the in the transverse groove located in the key face in the crossbar snaps into place. Still, the cross groove not absolutely necessary, since the crossbar is also on anywhere on the free wedge surface of the Guide rail arrangement can be applied. By Pulling the worktop towards the user will do so automatically brought into their angled position. The angle of inclination of the wedge surface in connection with the transverse groove is crucial for the Angle of inclination of the inclined Countertop. By simply pushing the Worktop this will return to its support level pushed onto the table frame. Can be used as a cross bar the longitudinal strut already provided on the table frame between the table legs.

The longitudinal groove-bolt connection between the Worktop and the frame, which are in the near the worktop, serves the horizontal mobility of the Countertop. Due to the presence of the bolt a pivot point is set around which the Worktop with horizontal movement at the same time is angled. The adjustability of the Worktop is essentially by the bolts guided in the longitudinal groove and the free Wedge surface of the guide bar assembly determined.

The slant of the worktop should be in Range from about 5 to 15 °, preferably at 8 ° because experience has shown that these values are the best ergonomic conditions.

Especially when using chairs, especially Office chairs, their seat and backrest area are adjustable, is the case with conventional tables Adjustment of these elements always makes no sense if the working position at the table, especially on one Work table that is taken by the user since he left the back of the chair with his back must to lean on the work table. By pulling and angling the Worktop can now be the user's back the back of the chair and thus a permanent, ergonomically favorable, relieving the upper body Working position in a relaxed position take in.
