The invention relates to a clamp for hose containing the tape clamping device and a positioning device that has at least one positioning element includes a base and a tooth that can be pressed into the wall of the hose.

This clamp is used to secure the hose to the nozzle. For this purpose, the clamp is put on the hose in the area of the pipe and tighten the tape on the hose using a clamping device. As a result of clamping the hose is fixed on the socket.

To manipulate with a clamping device, the working tool required. Therefore, for users clamps for the hose, it is desirable that the clamp was pre-installed on the hose, i.e. have a specific orientation relative to the hose, at least in the circumferential direction.

In WO 2004/044474 A1, which describes a clamp for hose of this type, it is proposed to install the ribbon positioning element, which has two teeth mounted on one base. Each tooth has a plot that is oriented essentially perpendicular to the base and the branching outwards, i.e. in the direction of the hose. This site is adjacent curved angle end. To secure the clamp on the hose needed a tool that using punch presses the base in the direction of the hose. The inside of the hose is retained by the socket. When the clamp that is they way fixed, take two clamping jaws, which impinge on the ends of the teeth on the side, i.e. in the circumferential direction of the hose, causing the teeth are moved toward each other. Due to this, the teeth are embedded in the wall of the hose and the clamp is attached to the hose.

The consolidation of this type requires a relatively high cost.

The basis of the invention lies to simplify the task of pre-installation of the clamp on the hose.

This problem is solved in the clamp for the hose above-mentioned type by the fact that the tooth has a section extending from the base to the inside in the direction of the indentation, and the end forming with this part of the obtuse angle.

If teeth of such form pre-installation of the clamp on the hose much easier. In principle, you only need to click on the base in the radial relative to the hose direction. While the end of the tooth, located at an obtuse angle to the exhaust from the base section, is embedded in the hose. This implementation is due to the location specified end under the first angle in the radial direction or parallel to it, and then, after introduction at a very small distance, the end of the tooth is deflected sideways. Since the end of the exhaust from the base of the plot may not follow this deviation, the tooth as a whole is bent. Upon further introduction of the end of the tooth in the hose tooth is bent between the near ends of the fastening on the basis of the thus, eventually he has a shape approximately corresponding to the shape of half of a paper clip. In hoses with normal wall thickness of the end of the tooth will not speak on the inner side of the wall, as in the implementation process it was quite biased in the circumferential direction.

The end of the tooth is preferably located at the end adjacent to the site, extending from the base. Thus, the tooth consists of two linear sections - terminal section and section protruding from the base. When a tooth is pressed into the wall of the hose, these two pieces are deformed so that they form together about a quarter of a circle. Of course, this quarter of a circle can join straight sections.

Extending from the base section preferably located at right angles to the base. Due to this force acting on the basis of, will best be transmitted to the tooth. Extending from the base section in any case stores near base of this rectangular orientation with respect to it. The tooth is deformed only further towards the end. The term "rectangular" here should not be understood in a strictly mathematical sense. However, the exhaust from the Foundation of the plot should be approximately parallel to the direction of indentation.

Obtuse angle FAV is preferably lies in the range from 110° up to 160°especially preferably in the range of from 120° to 150°. The tooth is particularly well pressed into the hose, if the angle is approximately 135°. In this case, the end of the tooth is moved in the circumferential direction inside the hose wall at least to the extent that it is embedded in the shell.

From the base preferably leave two teeth, the ends of which are directed towards each other. This achieves the balance of forces in the circumferential direction, i.e. no need to lock the base against lateral shifting in the circumferential direction. When both curved tooth finally, in cross-section they have a form similar to a stationery clip.

The obtuse angles of both teeth are preferably of equal value. The smaller the difference between the two angles, the better balanced forces in the circumferential direction. Mathematically exact equality is also not required.

The base preferably has a smooth outer side. This is, firstly, facilitates supply of the instrument. Secondly, in this case there are no elements that protrude radially outwards and may further interfere to install the clamp on the hose. When the clamp is installed, in the region of the positioning element is also missing items that interferes with the clip.

The base is preferably in the axial direction of the tion, at least one area, the tape clamp. This makes it possible to push the teeth into the hose out of the area, which has a clamping force of the clamp and prevents the full burst of the end of the clip through the wall of the hose under the action of the clamping forces.

Also preferably, the base is at least one site was performed in the axial direction for a tooth. This facilitates the positioning of the clip so that the tooth will be at a given distance from the end of the hose. It is only necessary that the end of the Foundation coincided with the end of the hose.

The positioning element is preferably spring jumper, the ends of which are connected with ribbon ties. The advantage achieved in the presence of the spring lintel, is that in the region of the positioning element, the tape may be located at some distance from it, when it is not tightened. When you remove the hose, i.e. the loosening of the clamp, a spring retainer pushes the tape.

Preferably, a spring jumper was connected with ribbon movably. This applies at least one end of a spring jumper. Thus, the spring retainer prevents the tightening of the tape.

While it is preferable that the spring retainer was located in the region of the clamping device. Spring jumper issue which play an additional function, namely, it prevents friction of the end of the tape and/or a fastening device on the outer surface of the hose when the clamp is clamped. The moving elements of the clamp when the clamp on the hose is only on the outer side of the spring lintel.

The following describes the preferred embodiment of the invention with reference to the drawings, in which:

figure 1 depicts in perspective a clamp for hose with two positioning elements,

figure 2 - positioning element in another embodiment, the,

figure 3 - positioning element before pushing in hose

figure 4 - positioning element after being pressed into the hose.

The clamp 1 hose contains the tape 2, curved into a ring so that its outer end 3 superimposed on the inner end 4. The ends of 3,4 tape connected clamping device 5 containing the clamping screw 6, which is engaged in extruded threaded recess 7. When tightening the clamping screw ends 3,4 clamping the tape 2 is moved in the circumferential direction of the yoke 1 to each other and the inner diameter of the clamp 1 is reduced.

The fastener 1 of this type is used for fastening a hose (not shown) on the nozzle. For this purpose, the clamp 1 is put on the hose, the hose is placed on the pipe and clamp the clamp 1. While it is desirable that the clamping device 5 was in a certain position on the hose and b is fixed lo so so the worker could use the tool to rotate the clamping screw 6.

To accomplish this positioning, shown in figure 1, the clamp 1 is provided with two positioning elements 8,9, described more when considering figure 2-4.

Positioning element 8 (positioning element 9 is made in principle in the same way) has base 10, which is approximately perpendicular to the inside space 13 surrounded by the tape 2, leave two sections 11, 12. Each plot 11,12 element is adjacent the tail section 14, 15 forming with the corresponding plot 11, 12 angle αapproximately 135°. Thus, angle α is an obtuse angle. The ends 14, 15 are directed toward each other and terminate each end 16, 17, respectively, which, if required, can be sharpened.

To secure the clamp 1 hose 18, as seen in figure 2, which was inspired from the inside to the fixed stop 19 in the place where the positioning element 8 must be pressed into the hose 18. Then positioning element 8 set ends 16, 17 of the tube 18 and with a stamp 20 are pressed on the positioning element in the direction of pressing of the arrow 21, i.e. in the direction towards the fixed stop 19 at the ends 16, 17 are pressed into the hose 18. Since the end sections 14, 15 are arranged at an angle to the direction of the indentation 21, the result agrogeneration element 8 with a stamp 21 ends 16, 17 do not move only parallel to the direction 21 of the recess, but also become the circumferential direction by the material of the hose 18. The farther the base 10 is moved on the outer surface of the hose 18, the more you move the ends 16, 17 in the circumferential direction, so that the "legs" of the positioning element 8, which in the state before implementing formed according to figure 3, the two rectilinear sections 11, 14 or 12, 15, respectively, now have the shape of an arc. When this positioning element 8 is located in the material of the hose 18 like a paperclip, i.e., the ends 16, 17 does not protrude from the hose inside.

Positioning element 9 is fixed directly on the tape 2, for example, by welding, soldering, bonding or connection by clamping or crimping. Positioning element 9 mounted on the tape 2 so that its teeth 22, 23, i.e. placed at an angle to each other, the sections 11, 14 or 12, 15 are located at a distance from the tape 2 in the axial direction. This makes it possible to ensure the impact of the stamp 20 on the base 10 outside of the tape 2 in the axial direction.

Positioning element 8 is located on the spring lintel 24, both ends of which are mounted elastically on the ribbon 2. Do this for each end of the spring jumpers are brackets 25, 26, which are bent around the tape 2. Positioning element 8 can is to be made as one piece with the spring lintel 24.

On both sides of the positioning element 8 in the circumferential direction of the spring retainer 24 has lugs 27, 28, which pre-installed the clip 1 is attached to the end of the hose 18.

Spring retainer 24 is where the overlap ends 3,4 tape, ie, where there is a clamping device 5. Therefore, due to the presence of the spring lintel 24 the inner end 4 of the tape or clamping device 5 when the clamping of the clamp 1 will slide directly on the outer surface of the hose 18, and the outer side of the spring lintel 24.

Shown in figure 2 positioning element 8 is slightly different from the positioning element 8 in figure 1, because it has a lug 29, which runs in the axial direction of the teeth 22, 23. The clamp 1, provided with such a positioning element 8 can be easily positioned in the axial direction of the hose 18 by combining the projection 29 with the end of the hose 18.

Positioning elements 8, 9 are located essentially diametrically opposite. Positioning element 9 mounted on the tape 2 is not moving and positioning element 8 installed on it somewhat floating. This allows a strong connection of the positioning elements 8, 9 with the hose 18, without compromising the effectiveness of the clamp yoke 1.

The clamp 1 at its inner side has also reginae device 30, which allows you to hold the clamp 1 in the clamped condition even when changing its diameter, which may be caused, for example, temperature.
