DE369907C - Chair with retractable seat - Google Patents

Description

Often one can observe people using their bodies through their bodies Bend over the chair to get closer to the desk. This suffers not only the chair, but also the person sitting, because with this type of seat the legs as well as the whole body become overexerted. The movement of the chair becomes part of it Out of bad habit, on the other hand, refrain from lack of time. Lies under the chair even a carpet or the like, then the moving away when getting up and the moving closer when sitting down, even more difficult. The invention creates a chair, which without changing his place on the floor comfortable getting up and Passing enabled while seated by the body weight, supported by ■ a slight forward movement that can be brought any closer to the table. |

The subject of the invention! is shown in the drawing, namely in the

The front pair of feet α, α ¹ is divided by two; Strive o, n, the rear pair of feet b, b ¹ through! two struts r, ρ stiffened. At the top of each foot there is a protruding tongue; c, c ¹ , c ² , c ³ are used. Through the connection! dungsstreben e, e ¹ are the pairs of feet α, α ¹ ; and b, b ¹ movably connected. The tongues | c, c ¹ , c ² , c ³ engage in corresponding slots located in the seat d I, so that the pairs of feet j α, α ¹ and b, b ¹ are articulated to the seat d. A claw g is attached to the strut η and a claw g ^{1 is} attached to the strut r. The spring sleeve / is articulated to the claw g by a bolt. The spring h, which sits in the spring sleeve /, is supported by the bolt of the claw g . The pressure bar i is so far into the spring sleeve / that the screw k comes to sit behind its head. The pierced end of the pressure rail i is articulated to the claw g ¹ by a bolt. The spring h is tensioned and pushes the seat d backwards (Fig. 1). Due to the weight of the person sitting on the chair, supported by a slight forward movement of the body, the seat d can be moved forward until the spring sleeve / hits the claw g ¹ (Fig. 2). Is d, it Seated on, so a _Q compresses the spring Ii the seat back so far d, to 'the head of the pressure rail i k proposes the screw. The path between the table and the chair is then free to pass by (Fig. 1). Any position between the two limit points can easily be achieved.

Since the height of the seat would be reduced by the inclined position of the feet when the seat d is shifted, shoes / and m are attached to the feet, which tilt onto their protruding tips when the chair seat moves forward and compensate for the height difference between the sitting positions.

Claims (2)

Patent Claims: ι. Chair with a seat that can be pushed forward, characterized in that the two pairs of feet (aa ¹ , bb ¹ ) united by struts (0 n, rp) are articulated to the seat (d) s ₀ , and! d & ß the seat is pushed backwards by a spring bushing (/) with a pressure bar (i) , which is tilted upwards and is hinged to the leg struts (n, r) , with the seat shifting backwards and forwards being limited by stops. 2. Stubl according to claim 1, characterized in that attached to the chair feet shoes (I, m) to compensate the height differences _go difference in the displacement of the seat by tilting their protruding tips. 1 sheet of drawings.
