FIG. 4 is a front view of the device according to FIGS Figures 1 to J5;

Fig. 5 is a section along the line 5-5 of Fig. Jj

Fig. 6 is a perspective disassembled an embodiment in two-part design; and

Fig. 7 is a perspective view of another embodiment of the

actual cutting part of FIG. 6, which can be used together with the handle according to FIG is.

The clamping band cutting tool 2oo according to Figures 1 to 5 consists of an elongated body 2o2 of essentially U-shaped profile. Side flanges 2o4 hang down in one piece from the flat main surface 2o6, see above that a flat U-profile is created in which the to be cut The tightening strap is in place as long as the device is on the tightening strap that is still closed.

At one end of the tool 2oo, a first opening 21o is punched out, which - viewed from above according to FIG. 1 from the side flanges 2o4, a web 212 at the head end of the tool and a further web 214 is limited. The edge of the web 214 pointing away from the web 212 can be seen in particular from FIGS. 1 and 3 V-shaped and forms the two converging cutting edges 216. The cutting edges 216 and the one pointing to the left in FIGS. 1 and 5 Embossed edges without a reference number form the second opening or recess 218 of the tool body 2o2.

As shown only in Figures 1 and 2, the side edges of the tool, which also forms a handle 2o2 depressed at 22o this way the ends to connect the ends of the tape lying in the channel of U-shaped cross-section 2o8 with one another. The one shown so far The tool is not only used to cut through a tensioning band, as will be described later, but can also firmly connect the two ends of a tape to one another. In addition, the device can now also to be constantly attached to the still closed one strap of a sea chest, so that it sort of paves the way the box participates and is always available at the place where the box is opened.

The tension band is therefore in the U-shaped channel, wherein it - see Fig. 2 - with its upper side against the lower surface B of the web 212 and with its lower side against the upper surface A of the web 214 rests. So if you have the body 2oo at the right end in the drawing according to Fig. 2 lifts up, the whole body at the same time forming a handle 222, then the cutting edges 216 pressed into the tape and cut it. The V-shaped Arrangement of the cutting edges 216 occur with progressive pivoting of the handle for opening purposes into the sides of the tape and then cut through to the middle.

At the other end of the entire device (on the right in the drawing), a longitudinal slot 222 is incorporated. if the whole tool can be removed from the tape to which it was initially attached by cutting open the tape cut in the way described above, you can use this tool to cut additional ribbons: one pushes that in relation to the belt surface

Tool raised in the longitudinal direction from the side with the slot 224 on or around the belt and rotates the whole tool now at the left end in Figures 1 to J5 around the axis of the longitudinal extension of the tape, whereby one shears off this further bond. This leads to the fact that you have a box that is closed with several straps is, only needs to be provided on a strap with the attached cutting tool, because after separation of the first Band on which the tool is firmly located, the tool comes free and now in the manner just described can cut the other tightening straps, on which no separate cutting tools are to be attached. This means that only one opening device is required per box, even if there are several straps.

The entire tool 200 according to the previous description is produced by punching and bending by the two openings 21o and 218 as well as the slot 224 punches, the web 214 is stamped through in which can be seen from the figures 4 and 5 resulting position pressed to the other parts of the tool. The side legs 2o4 of the tool will be made by bending. As can be seen from Figures 4 and 5, a closed cavity is created in the profile, the underside of which is formed by the depressed web 214 with the cutting edges through which the to cutting clamping band is guided, with which the tool is firmly anchored on the clamping band and transported with it can be. Of course, you can punch out the openings and the slot on the one hand and stamping them down of the web 214, on the other hand, with a suitable tool in one operation.

In order to be able to use the described tool

tern, the tool can have an expression 226 on the right Have end that is stamped from the normal plane of the sheet 2o6 upwards, so that you can see this expression for example, can grip with the gloved finger, or with any tool, e.g. a Screwdriver can perform. The expression 226 can be produced by a simple bending process. • Of course you can also borrow other resources to start with Provide for inserting a tool or a gloved finger under the actual tool. Man can also make this impression 226 so that you can drive with the toe of a boot underneath, so that you can only open a strap on the box with your foot.

A further embodiment of the device according to the invention is shown in FIG. 6: in this case there is the tool consists of two parts, namely the actual cutting head 25o and a handle 252 with which you can operate the cutting head. The cutting head 25o has a web 25 ^, on one side of which Cutting edge 256 is formed. The legs 258 of the U-profiles 250 are on themselves at their free ends folded back so that a guide 260 for receiving both the tape to be cut and the actual tape Handle 252 arises. When using is before the closing of an applied tensioning band, the cutting head 250 is pushed onto one end of the band and then is the tape stretched and locked. In a sense, the cutting head travels with the box. In this case a cutting head 250 will be provided to each tension band. Such a cutting head on a box is a Handle 252 given, which is expediently pushed into the guide 260 for this purpose, where it is

A speaking tight fit is held securely. One end of the handle 252 lies in the guide between the Tape and the bent edges of the side walls 258 and is held there by clamping. Of course you can also drill a hole through the handle, and separate the handle from a cutting head with a Attach a nail or the like to the box for transport.

As can be seen from the dash-dotted lines in Fig. 6, one end of the handle 256 is inserted into the cutting head of the side that has the cutting edge 256 is inserted.

Another embodiment or a similar cutting head for interaction with a handle 252 is shown in FIG Fig. 7 shown. The cutting head has the essentials the physical properties of the cutting head part in the one-piece tool, which is noted with reference on Figures 1 to 5 was explained. It has side walls 2o4 and the same openings or embossments 2I0 and 218 with a central web 214 and a terminal web 212. The web 214 has the cutting edges 216 on. You can now a handle 252 according to FIG. 6 in Slide in the cutting head according to FIG. 7 from the left and lift it up, whereby in a readily apparent manner the tape passed through the cutting head is cut.
