Description

The present furnace relates to a clamp for fastening elastic hoses to pipes, nipples and the same. Such hose clamps usually have a solid lietallband that is attached to the connection point, TfO the elastic hose on the fixed tube nndern the fixed nipple is pulled on, around the hose outside is wrapped, with the two ends of the metal band are firmly tightened by means of a screw connection and ensure the required contact pressure. To such hose clamps to attach or to loosen ,,, is required by turning it in respectively Unscrewing the respective screws of a certain Time expenditure that does not meet all needs, because in many cases there is a need to have the terminal can be removed quickly, i.e. with a single movement, and reassembled just as quickly. The present innovation brings the bar that meets this need to the technical one Act.

It consists of a hose clamp with a tightly tightenable Lietall strap around the hose and is characterized in that the Lietallband has a pivotably attached tensioning lever, of which a resilient, on other end of the tape attacking bracket goes out, whereby through

back of the tensioning lever against the band this underneath • The bracket is tensioned so that it rests firmly on all sides against the hose.

According to the further hiring, the resilient The bracket can be a curved wire bracket, but it is also possible to give the resilient bracket the shape of a curved one To give flat spring.

Laughing another embodiment of the innovation the resilient bracket is firmly attached to one end of the strap or, as an alternative, it is At one end of the belt, several different hose thicknesses adapted to the hooking mechanism for the springy bracket available.

Finally, the present hiring still contains the suggestion, the resilient bracket for the spontaneous generation of play to be stored in elongated holes of the clamping lever when unhooking.

Embodiments of the present firing are shown on the accompanying drawing. 3s show

Fig. 1 and 2 a first embodiment inVsö ⁰ distorted views. The tensioning lever is pressed against the lietallband, as it corresponds to the closed position of the hose clamp.

Fig. 3 shows a second embodiment of the An innovation, with the possibility of different oils terminal Adjust hose diameters.

The elastic band that surrounds the hose on the outside and is intended to produce the iesten pressure inwards is denoted by. IiIs sits in a xwsi 2 at its end Bracket 3 continues, which, due to its curved shape, looks like a

Clamping element acts. The bracket 3 is non-detachable at the end of the tape 2, but is mounted in an articulated manner. Ar attacks εη his other "inde into the holes of the clamping lever 4 ... 'ird the clamping lever 4 against the band 1 is pressed, a voltage is generated in the bracket 3, which is transferred to the entire band and its Pulls ends together tightly. The arrangement is such that when the lever 4, cuh. in the closed position, a constant moment holds the hose clamp in the closed position, so that automatic opening is ruled out is. To avoid any risk of accidental opening of the hose clamp to avoid, you can never use the 3end of lever 4 instead of it. 2 shows, to bend open, the run of the metal strip 1 customize.

The embodiment of the hose clamp shown in Figure 3 corresponds in its essential parts to above, but here the resilient bracket 3 is not firmly attached to the end of the tape, but engages in one of several recesses with which an abutment 5 located there is provided. You can in this embodiment Adapt the clamp to different hose sizes, i.e. hose diameters.

Next you also have the option, as Fig. 3 shows, the resilient bracket 3 in an elongated β of the clamping lever so that when the hose clamp is loosened, i.e. when the bracket is lifted, a play arises that makes it easier to remove the hose clamp made easier by the hose.

RA.765 313 * 21.1259 patent attorney 12.12.1959 / E. D.ipi.-ing, H. Gockel sheet on the letter dated in succession: patent attorney Dipl.Ing .. H. Fritz to: protection claims. 1.) Hose clamp for clamping hoses or the like. on the drill, nipple, etc. with a metal band that encompasses the outside of the hose and can be firmly tightened, characterized in that the metal strip is provided with a pivotable clamping lever (4), one of which resilient bracket (3) engaging at the other end of the tape goes out, whereby by pressing the tensioning lever against the tape this comes under tensioning the bracket to all-round firm contact. 2.) Hose clamp according to claim 1, characterized in that the resilient bracket (3) is a curved wire bracket. 3.) Hose clamp according to claim 1, characterized in that that the resilient bracket is a curved flat spring. 4.) Hose clamp according to claim 1, characterized in that the resilient bracket at one end of the tape (2) is undetachable is appropriate. 5.) Hose clamp according to claim 1, characterized in that at one end of the tape several different hose thicknesses There are adapted hooking options for the resilient bracket. β.) Hose clamp according to one of the preceding claims, characterized in that the resilient bracket for Generation of play when unhooking in elongated holes (6) of the Tension lever is mounted.
