Definitions
- the invention relates to a clamp for height-adjustable backrests with the characteristics of the Preamble of claim 1.
- Such clamps consisting of a guide part for a tube part of the backrest, as well as one Clamping device, such as a screw for the pipe part is clamped in the guide part known for a long time.
- a clamping body by means of a laterally arranged fixed engagement can be brought with the tubular part of a backrest can.
- the known clamps have many the disadvantage that the pipe part with time loosens.
- the object of the present invention is a Clamp for height-adjustable backrests for chairs to create that does not loosen permanently and that is easy and convenient to use.
- a clamping device for the Clamp the tubular part of a backrest from one Clamping body that swivels at an upper pivot point towards the pipe part in the guide part or one adjacent, firmly connected to this part is, and an actuator, the Actuator below the pivot point of the Clamping body, rotatable behind the pipe part the clamping body is arranged, and wherein the Actuator from its axis of rotation at least has two different diameters.
- the actuating body a snail or spiral cross section.
- the sprag is with a downward swivel lever on one Bolts are stored in the guide part and the lower end of the pivot lever lies on the actuating body at least one of his positions.
- the clamping body or the Swivel lever a spring-loaded latch for a Recess in the tubular part of the backrest.
- the clamp 1 consists of a Guide part 2 with a rear and two side walls, so that there is a U-shaped view from above Cross section results, the rear wall with two after inside bent incisions 2 'is provided so that a pipe part 3 of a backrest in the by Incisions 2 'and the rear wall formed guide is slidably guided, as well as from a Clamping device to the pipe part 3 in the desired Clamp insertion depth.
- the clamping device exists from a clamp body 10, which is connected to a swivel lever 4 together on a cross and above in the guide part 2 mounted bolt 5 is rotatably mounted, as well as from an actuator 6.
- the clamping body 10 lies on the tubular part 3 on.
- the clamping body 10 is by means of a pin 12, Snap noses or the like in the side walls of the Swivel lever 4 attached. He instructs for the bolt 5 its back a groove shown in Fig. 4 in more detail 17 on.
- the rear wall of the pivot lever 4 is in this Area left blank. In the position shown the clamping body 10 only on the pipe part 3 and clamps this not tight.
- the guide part 2 points in its Side walls holes 9 for attachment to a Seat carrier on.
- the pivot lever 4 which is a U-shaped in plan view, open to the tube part 3 cross section has and the side walls of the clamping body 10th partially enclose, is extended downward and can be engaged with an actuator body 6 become.
- the actuating body 6 is on a rotatable Cross bolt 7 in the side walls of the guide part 2 stored.
- the cross pin 7 is on one side, as in Fig. 3 shown, extended and with a handwheel Mistake.
- the actuating body 6 a helical contour. 3 is the weakest circumferential side of the actuator 6 bottom end of the pivot lever 4 facing. Will the Actuating body 6 rotated clockwise, so press finally the bigger page on the Swivel lever 4, whereby the clamping body 10 on the Pipe part 3 is pressed. The result is a high one Clamping force.
- the pipe part 3 is against unintentional pulling out and secured too deep insertion.
- a pull-out protection is integrated. This exists from a pawl rotatably mounted on the bolt 5 11.
- the clamping body 10 has, as in FIG. 6 shown, a vertical groove 16.
- the jack 11 extends downward in the groove 16 and has one Recess for the pin 12, the snap noses or the like, which also the path of the pawl 11th limited.
- the pawl 11 is supported by a spring 13 acted upon that between the lower end of the jack 11 and the rear wall of the pivot lever 4 on one Cone is stored.
- the pawl 11 presses on it Pipe part 3.
