Device for measuring and displaying the tension of lashing equipment

The invention relates to a device for measuring and displaying the tensile stress of lashing means, in particular of lashing straps and lashing ropes with a cylinder and

at least one spring arranged therein.
20th

Devices of this type are known. In addition to the elements already mentioned, they have two angled mutually standing lever arms, which with guide

medium, for example guide rollers for the lashing are provided. The lashing device is thus over the guide rollers and the cylinder containing the spring.

3Q ^the tension that the lever arms, which are at an angle to each other without load, are moved more or less against the force of the spring and are stretched in the process, depending on the tensile stress. On a scale arranged on the lever arms, then the under the influence of the

Tensile stress remaining residual angle can be read. \ The scale is normally not calibrated in degrees, but in units of tensile stress.

Devices of the known type have in the Practice proves. Nevertheless, there is the task of developing the previously known devices to them in particular to be able to build even more compact and to design the display device so that the displayed Value even in poor visibility, for example in the dark.

The solution to this problem results from the characteristic i

characterizing features of claim 1. In the 20

Claims 2, 3 and 4 specify special preferred configurations of the indicator to be provided .

The invention is described below with reference to the attached

The device is designated by 1 as a whole. It has a cylinder 2, which is usually from Metal, for example steel, and which must be sufficiently thick-walled in order not to absorb insignificant forces. The cylinder shown as an embodiment is on a End face closed with a closure plate 3,

® which depending on the production requirements in the cylinder

used or in one piece with the cylinder wall ■ | can be worked. The closure plate 3 has in

Lashing equipment can be installed. In the illustrated embodiment are the circumstances such that the

Device has a fork 5 on one side,

this screw bolt, the lashing rope 7 is attached to the device in a manner known per se.

In the cylinder 2, a spring 10 is arranged in the J; 5 present case is a disc spring assembly. The feather ■ f is based on an abutment 11, which is firmly with

the cylinder 2 is connected. In the illustrated embodiment, the shutter plate 3 serves as a counter-I '^ Q bearings 11. The drawing reveals further that the spring is penetrated by a rod 10 12, which leads out of the cylinder. 2 The rod 12 is enough

for this purpose through the passage opening 4 of the

closing plate. The rod 12 engages behind the spring 10, which in the illustrated embodiment by the Transverse bearing 13 happens. The transverse bearing 13 can be a rod which extends through a transverse bore 14 in the rod 12; however, the transverse bearing can also be a plate-shaped extension, a collar or the like. With the rod 12 is also an indicator 15; 15 ' connected, which is used to display the tensile stress.

or less visible, so that the train 35

So that it is easy to read the indicator 15 even in the dark, the indicator 15 consists of a light-reflecting or self-luminous mass which is inserted into depressions in the rod 12 is. The depressions can be engraved lines or points. Is it the pickled Mass around a light-reflecting mass, the rod must of course be connected to a light source, for example a flashlight. Act

If it is a self-luminous mass, then this is not necessary either and the reading can be carried out directly take place.

The indicator 15 allows an analog display, so the Display of the actually prevailing tensile stress.

According to another embodiment of the inventive concept the indicator, which is now denoted by 15 ', consists of a device which on acoustically indicates a once specified maximum voltage. Such an indicator is natural especially practical in poor visibility

It has been shown that for lashing heavy loads, as a rule, the same tension is always applied to the Lashing is applied. The tension is, for example, 500 kg with the indicator form 15 ' is set to this load by the manufacturer.

The indicator 15 'is usually curved in a concave manner Disc 17, which is preferably connected to the rod 12 in its central region 18. Also is In the stroke area of this disc, a stop 19 is arranged, which the concave initial shape of the disc when

Can fold the impulse into a convex shape. During this folding process, the pane gives a click-like sound Noise that can be easily heard. The sound is

so characteristic that it stands out well from other Ge-20

rustle, as well as the snapping of the tension ratchet can be distinguished. It is also made through the interior cavity of the cylinder 2, which acts as a resonance box, reinforced. The stop 19 can, as in the Drawing shown, be a ring which is attached to the inner wall of the cylinder 2 in a corresponding position is. But it is also sufficient if this stop is a pin or the like. Intended to the position (location) of the stop 19 be variable, it is proposed that the stop 19 take the form

of a pen, which from the outside into one of 35

5 Of course, the indicator 15 can also be at a and the same device can take the form of reflective or self-luminous markings as well have the shape of a click disk. Both execution forms should both individually and together from Inventive concept to be included.
