Abstract
Abstract An armrest for seating furniture is provided with a guide column extending in the vertical direction, with an armrest body which is guided thereon telescopically displaceably by virtue of a counter guide and with a locking device arranged on the armrest body for vertically fixing the armrest body in relation to the guide column. The guide column and the counter guide of the armrest body are formed in such symmetrical :manner in relation to an axis of symmetry extending in the vertical direction, that the armrest body is securable on the guide column in two different assembly positions rotated by 180° about the axis of symmetry one referred to the other.

155 words
An armrest for seating furniture, in particular for office chairs, comprising a guide column (9) extending in a vertical direction (V), an armrest body (1) which is guided thereon telescopically displaceably by means of a counter guide, which armrest body (1) comprises an arm bearing surface, a locking device (17) arranged on the armrest body (1) for vertically fixing the armrest body (1) in relation to the guide column (9), which locking device (17) comprises a locking member (16) releasably engaging with a locking recess (15) on the guide column (9), wherein the guide column (9) and the counter guide (8) of the armrest body (1) are formed in such symmetrical manner in relation to an axis symmetry (19) extending in the vertical direction (V), that the armrest body (1) is securable on the guide column (9) in two different assembly positions rotated by 180° about the axis of symmetry (19) one referred the other.
Claim 2
Dependent Claim
155 words
An armrest for seating furniture, in particular for office chairs, comprising a guide column (9) extending in a vertical direction (V), an armrest body (1) which is guided thereon telescopically displaceably by means of a counter guide, which armrest body (1) comprises an arm bearing surface, a locking device (17) arranged on the armrest body (1) for vertically fixing the armrest body (1) in relation to the guide column (9), which locking device (17) comprises a locking member (16) releasably engaging with a locking recess (15) on the guide column (9), wherein the guide column (9) and the counter guide (8) of the armrest body (1) are formed in such symmetrical manner in relation to an axis symmetry (19) extending in the vertical direction (V), that the armrest body (1) is securable on the guide column (9) in two different assembly positions rotated by 180° about the axis of symmetry (19) one referred the other.
Claim 3
Dependent Claim
47 words
An armrest according to claim 1, wherein in each case a row of locking recesses (15) extending in the vertical direction (V) is arranged on two lateral surfaces (13, 14), facing away from each other and extending in the vertical direction (V), of the guide column (9).
Claim 4
Dependent Claim
33 words
An armrest according to claim 1, comprising two ends (20, 21), facing away from each other, of the arm bearing surface (5) having different distances (a, b) from the axis of symmetry (19).
Claim 5
Dependent Claim
98 words
Armrest according to claim 1, wherein the locking member (16) is disengageable with the locking recesses (15) by means of an actuating device on the armrest body, and wherein the actuating device comprises an actuating slide (22) supported on the armrest body displaceably at right angles to the direction of engagement (E) of the locking member (16), which actuating slide (22) can be connected in the nature of a push drive with a locking member (locking bolt 16) via wedge surfaces (30, 31, 39, 40), adjoining each other, of said locking member (16) and said actuating slide (22).
Claim 6
Dependent Claim
47 words
An armrest according to claim 4, wherein with a wedge surface (30, 31) directing opposite the direction of engagement (E) of the locking member (16) the actuating slide (22) undercuts a wedge surface (39, 40) directing in the direction of engagement (E) on the locking member (16).
Claim 7
Dependent Claim
91 words
An armrest according to claim 4, wherein a closing wedge (48) spring-loaded in the closing direction (S) of the actuating slide (22) is supported on the actuating slide (22) displaceably at right angles to the direction of engagement (E) of the locking member (16), which closing wedge (48) with a wedge surface (47) directing in the direction of engagement (E) drives a wedge surface (46) directing opposite to the direction of engagement (E) on the locking member (16) and is supportable the actuating slide (22) opposite to its opening direction (O).
Claim 8
Dependent Claim
63 words
An armrest according to claim 6, wherein the actuating slide (22) comprises a substantially U-shaped external cross-section, its wedge surfaces (30, 31), the part of the locking member (16) comprising the corresponding wedge surfaces (39, 40) and the closing wedge (48) being arranged within the internal space of the actuating slide surrounded by external walls (23, 24, 29) of the actuating slide (22).
Claim 9
Dependent Claim
58 words
An armrest according to claim 7, wherein the actuating slide (22) is displaceably supported on the external side of the armrest body (1) via guide webs (25, 26) projecting inwards from the external walls (23, 24) of the armrest body (1), which guide webs (25, 26) engage with corresponding guide grooves (27, 28) on the armrest body (1).
Claim 10
Dependent Claim
63 words
Armrest according to claim 7, wherein the actuating slide (22) is provided with a projection (54) projecting from a U-base portion (external wall 29) outwards substantially at right angles to the direction of displacement (V), at the free end of which projection (54) a further guide web (55) for engaging with a corresponding guide groove (56) is formed on the armrest body (1).
Claim 11
Dependent Claim
45 words
An armrest according to claim 4, wherein the locking member (16) supported displaceably in the direction of engagement (E) in a wall opening (41) of a wall (7), surrounding the guide column (9) and forming an inner guide opening (8), of the armrest body (1).
Claim 12
Dependent Claim
