Stackable row chair with armrests

The innovation concerns a stackable row chair Armrests, the armrest supports of which are arranged laterally on the legs of the chair frame that open downwards in a V shape are, the armrest supports in the position of use of the Chair are employed parallel to the level of the side legs.

In such chairs, which are used both for individual seating and for row seating, arise Difficulties due to the requirement of stackability. The armrests prove to be an obstacle, so only certain shapes are possible.

When the chairs are arranged in a row, armrests and Armrestless chairs alternately set up next to each other and firmly coupled together. Because of the required stackability of the chairs and the resulting arrangement and shape of the armrests are available in the chair-armchair-chair series on the one hand an asymmetrical picture, on the other hand the seats of the chairs are created by the laterally protruding armrests constricted.

To enable the available width of the Seats of neighboring chairs are not impaired by protruding armrests when the chairs are set up next to each other and that there is no different axis dimension in a chair-chair row, one has gone over to the To mount armrests on a carrier that has a free passage for nesting the armrest carrier of stacked chairs owns. The free passage is covered by a backrest that can be folded away to the side. By training a free Passage in the armrest supports, which can be opened by folding away the Armrests is to be opened to stack the chairs on top of one another, the armrest supports and the

Armrests and thus the narrowing of the seat of an adjacent chair avoided. For the user there is free passage of the armrest support covered when using the stacking chair. For this purpose, the armrest can be folded onto the armrest support attached and locked in the position of use.

But this construction also requires a very specific armrest and armrest support construction. That’s a any chair design blocked. Furthermore, it can close due to unconscious handling of the foldable armrest Pinch injuries occur because the swivel connection is in the immediate vicinity of the hands. This risk is increased if the armrest lock is not properly closed or opens automatically due to wear and tear. Besides, the Opening the lock for the purpose of swiveling out the armrests is cumbersome.

The task at hand is to design armrests and armrest supports so that armrests can be designed in any way and armrest support is made possible while ensuring that they can be stacked and lined up. Also supposed to be a cumbersome Tampering with the armrests for the purpose of stacking the chairs can be avoided.

These objects are achieved according to the invention in that the armrest supports rigidly adjoining the armrests laterally limited in the connectors attached to the chair frame pivoted and are automatically and releasably locked in the pivoted, vertical setting.

The possibility of swiveling the armrest supports together with the armrests fixed to them means that emigration is over the handicap area in the stacking position of the chairs possible, therefore the armrests and their supports can be designed in any shape obtain. The swivel joints are also moved from the hand area down below the seat level, so that Injuries are excluded.

According to a further idea of the innovation, the armrest supports are mounted on side arms on pivot pins arranged in the connecting pieces and are in the pivoted-out position
State with sloping end flats against the connecting pieces as a swivel limit.

This is the focus of the armrest support and the
Armrests on the side next to the pivot pin, so that the | automatic unlocking when stacking the chairs that
Swing the armrest support out to the side by itself.

The locking is done according to the innovation in that
the armrest supports with fixed retaining bolts in
the vertical beam adjustment to engage in the pawls,
which are guided against the pressure of springs in a vertical direction in the connecting pieces. In an embodiment of the invention, the pawls are with their lower
Leading ends in the locked position over the connecting pieces | and hit the frame when the chairs are stacked ^! of the lower chair.

When the chairs are stacked, the protruding ends of the

The locking pawls are locked upwards by the weight of the chairs.

pivot outwards automatically. A special handling 1 for initiating the stacking is therefore not necessary. \

On the side of the V-shaped downwardly opening legs 1o of the chair frame is the armrest support 1 with the armrest 9. On the upper transition curve of the legs 1o, the connector 5 is attached, in which the armrest support 1 is pivoted outward. , _tii A side arm 11 is attached to the armrest support 1,

which is mounted on the pivot pin 7 arranged in the connection piece 5. So that the pivot bearing of the armrest support lies outside the center of gravity of the support, so that the armrest support 1 swings outwards by itself when the pivoting movement is released. In the swiveled-out state (FIG. 2), the armrest support 1 lies with its obliquely extending end flat 8

against the connector 5. This is how the pivoting movement is limited to the outside. In this armrest setting, the stacking space for the chairs is released.

Within the connecting pieces 5, the pawl 2 is mounted displaceably against the pressure of the spring 3. In his lotrechi In the use position (Fig. 1 and 3), the armrest support 1 engages with the retaining bolt 6 attached to it. The pawl 2 is pressed down into the locking position by the compression spring 3. In this setting the pawl protrudes; with its lower leading end 4 over the connection piece 5 when stacking a chair on a Stu standing underneath] the protruding end 4 meets the connector 5 of the lower chair, and win under the weight of the chair the pawl 2 moved upwards so that the retaining bolt ι is released, and the armrest support 1 automatically after ' . swings out on the outside. When lifting the chair out of the stacked one Position in the position of use, the armrest is' gripped and raised, whereby an automatic locking the armrest support 1 behind the pawls 2 is effected.
