Definitions
- the invention relates to an office table with a table top designed to be adjustable in height and inclination with respect to its frame and which is assigned to the frame in the form of a desk, consisting of a frame with two side cheeks, at the lower ends of which are arranged on the same side as the table top.
- Office tables of this type are generally known and are in use and, for ergonomic reasons or for adjusting the most favorable position to the user, are generally not only adjustable in height but also in inclination with respect to the table top. Because of the freedom of movement of the legs underneath the table top that is as unimpeded as possible, such tables are more or less designed like a desk today, ie the table top is only cantilevered to the seat side between two side cheeks, at the lower ends of which cantilevered, but cantilevered compared to the table top there are short footrests. With such previously known tables, it is now relatively difficult to assign the table top to the two side cheeks or the actual table frame, both adjustable in height and inclination, since this leads to relatively complex fittings which are to be arranged between the table top and frame.
- the known side bolsters for tables of this type are generally two-part telescopically shaped, cross-sectionally flat profile tubes, of which the parts which can be pulled out upwards must be connected by a suitable crossmember in order to secure the support and tilt fittings for them
- a suitable crossmember in order to secure the support and tilt fittings for them
- the relatively thin-walled profile tubes of the side cheeks are not used for this can in which, for the purpose of height adjustability, for example, adjusting spindles are arranged, which must be connected to one another in order to be able to be adjusted uniformly by an actuating crank from both side cheeks.
- the invention has for its object to improve an office table of the type mentioned in such a way that the elements required both for the height and for the inclination adjustment of the table top are easy to implement and the adjusting processes are easy to handle, with the proviso not to have to design the side walls as two-part telescopically displaceable test tubes and to be able to do without mechanically complex tilting fittings for tilting the table top.
- This solution is practically an adjustable triangle: the sides of which are formed by the slider, by the tabletop support strut uxtci from the tabletop itself or the tabletop support, the entire triangle with its slider part being height-adjustable in the side cheek in question, ie the support strive and the table top participate together in the height adjustment luug; but not the side walls, of which only a small part is designed as a guide channel for the slide rods, which will be explained in more detail. It is essential that the table top in the highest position with the upper ends of the side cheeks are arranged on the inside vertical slot guides for the table top or table top support joints.
- the guide channels arranged in the side walls, in which pressure springs are simply located under the slide rods, are also used for the pressure load on the slide rods.
- the "norma position" of the table top corresponds to its maximum position, which does not require any special stop limitation, because the Provide articulated processes on the slide rods, to which the support struts for the table top are articulated.
- the design according to the invention also creates the advantageous possibility of advantageously attaching a cable duct extending along the rear edge of the table top, the attachment of which to the table is generally required, advantageously at the upper ends of the slide rods can, who thus participates in any height adjustment and remains flush in any position of the table top.
- the table top in the office table according to the invention is always adjusted between this normal position and a possible lowest position, which is defined by the lower edge of the slits involved in the side cheeks.
- Fig. 1 partially in section and in side view of the office table
- Fig. 3 is a plan view of the frame of the office table without
- Fig. 5 shows another embodiment of the office table
- FIG. 6 is a top view of the office table according to FIG. 1;
- Fig. 7 shows a section along line IV-IV in FIG. 6;
- Fig. 9 enlarged in section and in side view the assignment of cable duct and table top
- FIG. 10 shows a special and preferred embodiment for the height adjustment and parallel guidance of the slide rods;
- Fig. 11 in side view of the Volunteertis ⁇ h in connection with the imple mentation form according to Fig. 10 and
- FIG. 12 is a perspective view of the entire folding unit for the embodiment of the table according to FIG. 1.
- the office table consists of a frame 33 formed from two interconnected side walls 1, on which the table top 7 is arranged so as to be adjustable in height and inclination.
- the guide channels 2 of the side walls 1, d are mounted on:, height-adjustable and fixable slide rods 4, on the upper ends 5 of which the table top 7 is articulated and on whose pivotable table top support brackets 11 are arranged, the ends 12 of which are at the table top two positions are designed to be fixable with the table top 7.
- the articulation of the table top 7 is not provided di rectly on the slide rods and the support beams 11, but between these elements and the table top 7, a support frame 15 is arranged as a table top support 8, on or on which the table top 7 in a suitable manner, remains in its plane, is displaceably mounted, in order in this way to have the advantage of being able to access it with cable duct 17 fastened to the slide rods 4.
- the slide rods 4 are as deut ⁇ Licher of FIG. 12 can be seen, with jaws 3 and with Klemm ⁇ screw 3 'is provided, which according to FIG. 12, the pusher rods 4 im.Bereich a slot 4 1 succeed. Each slide rod.
- the push rod conditions, 4 and the relevant walls of the guide channels 2 are each equipped with a plurality of snap-locking elements 14, which, in selected positions, allow a provisional locking of the correspondingly depressed table top 7, which is then secured by the clamping screws 3 '.
- the tabletop support beams 11, which do not necessarily have to have the arch shape shown, are articulated on the slide rods 4 and with their table-top ends 12 slidably and pivotably on the table top 7 or on the support frame 15, as shown in the embodiment, attached.
- small eccentric clamping elements 16 are suitable, with which a screw head can be clamped against the slotted link bracket 12 1 at the end of each table top support bracket 11. Since the articulation point of each support bracket 11 also moves when the slide rods 4 are adjusted in height, the side cheeks 1 must of course be provided with a correspondingly long slot 10 in this area. The same applies to the joints 6 at the upper end of each slide rod to which the table top 7 or the support frame 15 is articulated.
- These side slot guides on the side cheeks 1 are designated by 29.
- a locking linkage 35 (right side in FIG. 3) with an adjusting lever 36 can be provided, with which the ends 12 of both support beams 11 can then be fixed simultaneously.
- flank wall parts 18 of the side cheeks 1 are provided with a recessed wall part, as a result of which a cheek recess 19 is formed on the outside of each side cheek 1, in which the respective support bracket 11 is guided, as described by means of the adjustable and fixable slide rod 4 arranged in the side cheek 1.
- a roller 37 can be arranged inside the slot-like slot 10 ', which sits on a connecting pin between the cheek-side end 20 of the support bracket 11 and the slide rod 4.
- the other end 12 of the support bracket 11 on the table top is fixed on the table top 7 or on the support frame 15 in one way or another, as described for FIG. 3.
