Tripod camping chair l

The present invention relates to a foldable tripod camping chair.

The previously known three-legged chair uses a rather complex connecting block to connect the chair legs, as shown in Fig. 3. This design has the disadvantage that the chair legs cannot be folded up in a very small space. The bearing of the chair legs in the connecting block is statically overdetermined by the play-free mounting of the chair legs in the pivot point. This means that it is possible that the static forces are absorbed in the pivot point, which can lead to premature wear or failure due to the small contact surface of the chair legs in the pivot point. The positioning of the connecting block is not clearly separated from the force absorption.

Another disadvantage is the rather complex production of the connecting block.

Another variant is to connect the chair legs with a connecting star as shown in Fig. 4. This design has the disadvantage that the cross-section of the chair legs is greatly weakened at the point subject to the highest stress and the force connection occurs at the pivot point, which can lead to premature wear or failure due to the small contact surface of the chair legs at the pivot point

The present invention improves the conventional three-legged chair as follows:

1. A closed ring is used as a connecting element, which has three radial holes as shown in Fig. 2 at an angle of 120°, into which pins are pressed that position the ring on the chair legs. Since the pins in the hole in the chair leg have some play, the pins are not loaded when the chair is unfolded. The force connection only takes place in the ring, i.e. all static forces are absorbed by the ring. The positioning of the connecting ring on the chair legs is thus separated from the absorption of the static forces.

The chair has a very high static load capacity due to the self-contained structure of the retaining ring.

2. The connection of the chair legs by a ring allows the chair to be folded up in the tightest of spaces

3. The textile seat cover is attached to the chair legs with removable rivets, so that the seat cover can be removed at any time, for example for cleaning purposes.

Claims (1)

Expectations: Foldable tripod camping chair characterized by: three tubular chair legs (1) made of light metal, a connecting ring (2) which is provided with three radial holes at a distance of approximately 120° with pressed-in positioning pins (3) which position the ring in its intended position on the chair legs, whereby the hole in the chair legs into which the positioning pins are inserted is slightly larger in diameter than the positioning pins, so that the force connection when the chair is loaded only takes place by interlocking the chair legs in the retaining ring, Protective caps (4) on the upper and lower ends of the chair legs, whereby the textile foldable seat (5) is attached to the chair legs with removable rivets (6).'
