Support arm for stored devices

A support arm for stored devices, which is pivotably seated in a holder fastened to a fastening surface and can be horizontally adjusted into a pivoted-in position and a pivoted-out position. In the pivoted-in position the support arm extends approximately parallel with the fastening surface and in the pivoted-in position extends perpendicularly with respect to the fastening surface. If the holder is designed as a cup having a front horizontal guide slit facing away from the fastening surface, and a rear horizontal guide slit facing the fastening surface, the support arm is inserted into the two guide slits of the cup and is held therein, and the front guide slit and the rear guide slit limit the pivot movement of the support arm, wherein the front guide slit in the seating wall for the support arm has two receiving grooves, in which the support arm can be brought into the pivoted-in and pivoted-out positions and can be fixed therein without being pivotable, then a pivoted seating without bearing bolts is created and results in defined pivot settings, which improve the operational dependability.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a support arm for stored devices, which is pivotably seated in a holder fastened to a fastening surface and can be horizontally adjusted into a pivoted-in position and a pivoted-out position, wherein in the pivoted-in position the support arm extends approximately parallel with the fastening surface, and in the pivoted-in position extends perpendicularly with respect to the fastening surface.

2. Discussion of Related Art

Various support arms are known, wherein the support arm is rotatably seated in the holder. In this case, the holder can also be embodied as a fastening element, which is fastened to the wall forming the fastening surface. The rotatable seating is provided by bearing bolts and does not provide an unequivocal fixation of the two pivot positions. This includes a danger that the pivoted-out position in particular is not unequivocally secured and can be inadvertently changed. Thus, the stored device can only be stored insufficiently secured on two support arms.

SUMMARY OF THE INVENTION

It is one object of this invention to provide a support arm of the type mentioned above but in which at least the pivoted-in and pivoted-out positions of the support arm are secured and cannot be inadvertently changed.

In accordance with this invention the above object is achieved with a holder designed as a cup having a front horizontal guide slit facing away from the fastening surface, and a rear horizontal guide slit facing the fastening surface. The support arm is inserted into the two guide slits of the cup and is held therein, and the front guide slit and the rear guide slit limit the pivot movement of the support arm, wherein the front guide slit in the seating wall for the support arm has two receiving grooves, in which the support arm can be brought into the pivoted-in and pivoted-out positions and can be fixed therein without being pivotable.

A pivoted seating without bearing bolts is achieved by the two guide slits in the cup, which results in a secure pivoted-in position and pivoted-out position of the support arm with the two receiving grooves in the seating wall. If the two receiving grooves of the front guide slit are separated from each other by a separating strip on the seating wall for the support arm, the width of the front guide slit in the area of or near the separating strip corresponds approximately to the vertical dimension of the support arm, and the width of the rear guide slit is slightly greater than the vertical dimension of the support arm, then pivoting of the support arm into the respectively other end position can only be performed by lifting the support arm. In this case the height of the separating strip determines the lift of the support arm required for this purpose. The vertical dimensions of the guide slits assure that this lift can be performed and that the pivot movement of the support arm is not hindered.

A further advantage of the novel pivoted seating of the support arm is that the support arm is adjustably guided in the guide slits in an axially non-displaceable or limited axially displaceable manner by stops at the ends, wherein the stops at the end of the support arm facing the cup are arranged inside the cup or outside the cup. The projecting length of the support arm can be unchangeable, or can be matched to the depth of the stored device.

Because two support arms are required for the stored device, in one embodiment two different cups are provided, which are designed mirror-reversed and with the guide slits relative to the center planes extending perpendicularly with respect to the fastening surfaces. In this case the two support arms differ by their oppositely directed pivoting-out movements. This can also be achieved with identically designed cups, if the cups are simply fixed in place and rotated by 90° on fastening legs of angled fastening brackets. In this case the fixation in place can occur if the area of the cup bottom of the cup is fixed in a fastening receiver of a fastening leg of a fastening bracket, wherein the other fastening leg extends parallel with the fastening surface. The fastening brackets offer selective attachment if both fastening legs of the fastening bracket have fastening bores, and if the support arms with the fastening bracket are selectively fastened on a horizontal wall of storage device or the like, or on a vertical fastening profile side of a horizontal mounting rail or the like.

DESCRIPTION OF PREFERRED EMBODIMENTS

The holder shown inFIGS. 1 to 4has a cup10as its base elements which, with a bottom17, is fixedly connected with a horizontal fastening leg21of a fastening bracket20. The fastening bracket20has a second fastening leg23, which is oriented parallel with respect to the fastening surface from which the supports arms are pivoted, so that they project out perpendicularly. Both fastening legs21and23have fastening bores22and24. The fastening leg21can have a receiver25, into which a shoulder of the cup bottom17is inserted. A rear horizontal guide slit15facing the fastening leg23, i.e. the fastening surface, and a front horizontal guide slit11facing away from the fastening surface, are cut into the wall of the cup. The guide slits11and15form support walls for the support arm in the area of or near the open underside of the cup10, into which the two guide slits11and15are inserted. At its end attached to the cup10, the support arm30can have stops, which maintain the support arm30in the guide slits11and15, so the support arm can be axially adjusted in a limited way, or can be therein held immovably. This can be obtained if the stop facing the cup10is attached to the underside of the support arm30on the inside or the outside of the cup10.

The stops31at the front end of the support arm30are oriented upward and fix the stored device in place.

As shown by the sectional view inFIG. 2, the support arm30can assume a pivoted-in position30eand a pivoted-out position30ain the guide slits11and15. The guide slit11only needs to have a width slightly larger than the corresponding dimension of the support arm30which, for example, can be designed as a square hollow profiled section. The vertical ends of the guide slit15limit the pivot movement of the support arm30. The front guide slit11forms two receiving grooves12and14in the support wall, which are separated from each other by a raised separating strip13. Here, the receiving grooves12and14are located on a common level with the support wall16of the guide slit15.

In the holder shown inFIG. 1, the support arm30can project away toward the left in the pivoted-in position30eand can be brought into the pivoted-out position30a, which extends vertically relative to the drawing plane, as shown by the dashed lines inFIG. 2. Pivoting can also occur in the opposite way if the cup10′ in accordance withFIG. 5is embodied mirror-reversed relative to the center plane x, or is attached rotated by 90° around the vertical center axis. The vertical width of the guide slit11over the separating strip13must at least correspond to the vertical dimension of the support arm30, so that the pivot movement is not hindered. With the rotated cup10′, the receiving groove14′ defines the pivoted-in position30e, which is oriented to the right, and the receiving groove12′ defines the pivoted-out position30aof the support arm. The pivoting movements Sle and Sre of the stored device inFIG. 5are oppositely oriented when the support arms30are moved from the pivoted-out positions30ainto the pivoted-in positions30e. This also applies to the opposite pivot movement out of the pivoted-in position30einto the pivoted-out position30a. Prior to pivoting of the support arms30, the support arm30must be lifted upward by a lift movement H sufficiently far, so that it can be displaced over the separating strip13.

The two fastening brackets20inFIG. 5are attached to the underside of the stored device50forming the horizontal fastening surface by screws26, washers27and28and nuts29. In a similar manner, the fastening brackets20can also be attached by screws61and nuts63to a vertical profiled side62of a horizontally seated or seatable mounting rail60, as shown inFIGS. 6 and 7. In this case the support arms30, which are pivotable in opposite directions, can be brought into the pivoted-in position30efacing each other if different cups10and10′ are used, or identical cups10are fixed on the fastening brackets20in different rotatory positions.
