(R 5636111163C ² J.

Closures with the help of. Rotary knobs, these are knobs with an axis that make it possible to to attach an eye or an eye to the button body or to detach it from it, how it z. B. is the case with closures of motor vehicle tops, tents and others the inconvenience that opening or closing is only possible from the side, . on which the button top is located, either only on the outside or only on the inside.

This evil should be the. eliminate the present invention what is achieved by that the axis of the knob is completely through the knob body and the part on which it is fixed, passes through it, and that the one opposite to the ordinary head Side carries a second head, which enables actuation from both sides will.

Shown are various embodiments of the present invention shown.

Fig. Ι is a longitudinal section through a first embodiment, namely a rotary knob with coil spring.

Fig. 2 shows a section along the line xx in Fig. 1.

Fig. 3 shows a longitudinal section through a rotary knob with a leaf spring, specifically for attaching a rigid part to a flexible part.

Fig. 3b is a section along the line yy in Fig. 3.

Fig. 4 shows a rotary knob for connecting two flexible parts.

Fig. S is a section along the line zz ■ in Fig. 4.

Fig. 6 shows a top view of a button according to Fig. 4.

Fig. 7 shows a button in longitudinal section, similar to the design according to Fig. 4, y-but with a covered eye.

Fig. 8 shows another embodiment for joining two flexible parts different kind.

Fig. 9 is a section along the line aa in Fig. 8.

In the embodiment, according to Fig. 1 and 2, the button consists in a known manner of a shell α of oval or any

Cross-section; this shell is in some known manner on one of the fabric parts, e.g. B. b, attached. Inside this shell α lies the square one with the ordinary one; Head e connected axis c.

A helical spring d lies against a collar of the axis c and the head e in Dekannter; Way in depressions in the lid of the bowl α firmly to determine the head in the desired j position, either to open '. of the closure ¹ the Augeg to remove 'may or festzu- to close the eye; keep.

According to the invention, on the free end of the axis c, a second head /, the z. B.> made of metal is suitably curved, on- j

riveted or otherwise fastened. The second !

Part of fabric g connected to the first '.

is to be provided ^{with an eye 1,}

a that -should cover the bowl, as it is in Fig. Ι is shown.

opening and closing of the button takes place in a known manner with the aid of the head c of the side on which the button body is located; from the other side you can now open and close with the help of the head /.

In the embodiment according to Fig. 3 and 3b, the axis c in a manner known per _ held in the against each other by 90 ⁰ positions rotated for opening and closing by means of two leaf springs Ii ¹ and Ir, the α lie in the interior of the shell and located in two Create opposite sides of the square axis c . The embodiment shown in Fig. 3 shows a button with two heads, which is used to connect a fabric or leather part g with a wooden or .Metalleilwand i . The axis c is so long that it passes through the width of the wall.

In Figs. 4, 5 and 6 it is. a knob with leaf spring shown for connecting two flexible parts g and b, such as. B. tent walls, canopies o. The like. The second head f of the button consists of an arcuately curved metal band, as shown in Fig. 4. At the highest point of the arch a hole f ^{1 is} drilled in the middle, which allows the passage of the tool for riveting the head f with the axis c .

In the embodiment of Fig. 7, the eye is g ¹ in a known manner, covered by a plate g ~, whereby this embodiment obtains a better appearance.

The embodiment according to FIGS. 8 and 9 finally shows a button with two shells α ¹ and ar, which are attached in opposite directions to the fabric part b. One of these bowls, e.g. B. the shell ar contains the leaf spring Λ ¹ and h ² , the other is made of wood, metal or other material. This arrangement allows the eye g ¹ to be attached to one side or the other of the fabric b, as shown in solid and dotted lines in FIG. This arrangement can also be attached to a rigid part in order to connect a flexible part therewith.

In order to facilitate the attachment of the eye or the knob body to the flexible leather or fabric parts, a strip of leather, fabric or other material is placed under the eye or the shell, which enables Avird to apply the necessary pull to the eye on the button body bring to. This strip can also be formed by simply bending the flexible part g , as shown in Figs.

Claims (3)

Patent Claims: 1. Rotary knob, in particular as a closure for roofs of motor vehicles and the like., In a known manner, consisting of an axis with a head in a Button body, in which it is resiliently held, can be rotated, and the rotation of which has the purpose of holding an eye or letting go, into which the button body can freely penetrate, characterized by that the axis of rotation passing through the button body is at the end opposite the first head is provided with a second head, so that the. Rotary knob on the car top both can be rotated from the inside as well as from the outside. 2. Rotary knob according to claim 1, characterized in that the one semicircular bent metal band formed second head opposite the attachment point the axle is provided with an opening through which the head can be riveted or otherwise fastened can be done on the axis. 3. Rotary knob according to claims 1 and 2, characterized in that the knob body (a) consists of two shells (α ¹ , σ ² ) made of metal, wood o the attachment of the eye of the other hood part can be done on both sides of the button.
