  • TOOL FOR TENSIONING A TAPE WRAPPED ABSTRACT A tool is provided for tensioning a tape around AROUND AN OBJECT AND FOR CONNECTING an ob ect, for connecting the ends of the tape and for cutting THE ENDS OF THE TAPE AND CUTTING OFF off the surplus, and the tool comprises a pivotal handlever en- THE SURPLUS gaging an element with a cutout which receives a pin on a w Claims, 4 Drawing Figs dravvtng bar engaged w th tape gripping and tensiomng devices.
  • the invention relates to a tool for the tensioning of a tape wrapped around an object and for the connecting and cutting off of the tape ends, after a preset tension has been reached.
  • the tool has a support for a lock connecting the tape ends, a device connected with the hand lever of the tool for gripping and tensioning the tape, and a cutting device which can be automatically operated by the hand lever when the tape tension exceeds a value set by the initial tension in a spring.
  • a tool is known in which the gripping device for the tensioning of the tape end is mounted on one arm of a tong, while the other arm carries the support for the lock and the cutting device, such cutting device then being coupled with the firstmentioned arm for carrying out the cutting operation when the tape tension exceeds a certain value.
  • the cutting movement is brought about through the relative motion of the tongs arms and therefore is necessarily associated with a further tensioning movement which is disadvantageous.
  • An object of the present invention is to provide a tool of the type as described above in which the tensioning and cutting ofl' movements can be carried out completely separate from each other.
  • the tool according to the invention comprises a connection of the hand lever with the tensioning device by means of a coupling which engages above a certain force limit, and a stop is provided which restricts the movement of the hand lever to a first part of the total movement as long as the coupling is engaged, while the cutting device is effective only in the second part of the total range of movement of the hand lever.
  • the tensioning movement is restricted to the first part of the range of movement of the hand lever, while the cutting off movement can take place only in the second part of the range of movement of the tensioning lever.
  • the transition of the hand lever from the first part to the second part of its possible range of movement is dependent on inoperativeness of the stop arising only when there is sufficient pull at the tensioning device.
  • the tool also relieves the hand lever of tape tension during the cutting operation, and it also has the advantage that it permits a particularly simple construction, because the coupling devices between the hand lever and the tensioning device on the one hand and the cutting device on the other can be constructed in a very simple way.
  • the coupling advantageously comprises between the tensioning device and the hand lever an inclined surface at one part and at the other part a glider acting together with the inclined plane, a spring being provided which prevents the glider from slipping from the inclined surface under the influence of the tape tension as long as the desired tape tension has not been reached.
  • the inclined surface is arranged at a certain angle to the vertical in the pulling direction of the tensioning device, so that the glider permanently tends to slip from the inclined surface, but is prevented from doing so as long as the force component causing its transverse movement is smaller than the spring tension.
  • the force limit at which the tensioning device is disengaged thus depends on the inclination of the inclined surface with regard to the vertical to the pulling direction of the tensioning device, on the positive direction of the spring, and the initial tension in the spring.
  • the force limit is suitably adjusted above the initial tension in the spring; but the other two factors of influence can also be used for this.
  • the inclined surface may be in the form of an edge cutout with an inclined flank on a movably supported part, for example, in the direction of movement of the tensioning device, into which cutout the glider which is connected with the tensioning device and designed as a roll or the like is urged by a spring.
  • An edge is arranged next to the cutout on the side of the inclined flank extending generally in the tensioning direction, said edge being adapted to receive the glider after it has slipped from the cutout.
  • the stop is advantageously provided at the tensioning device and on the other, on the tool body.
  • the stop is so designed that a slipping out of the glider from the cutout below the stop force is not possible. This can, for example, be insured by providing the stop with a hook which prevents the relative motions of the inclined surface and the glider required for the disengagement of the tensioning device, or by giving the stop an inclined direction which is in correspondence with that of the inclined surface, so that in the interaction of stop and tensioning device, no force component can come into existence acting to disengage in the direction of the inclined surface.
  • the part carrying the edge cutout is suitably under the load of a spring which presses this part and the hand lever back into the normal position.
  • Another spring can be provided which returns the tensioning device, after its disengagement. back to its normal position.
  • the tensioning device is combined with a stopping device preventing the return movement of the ten sioned tape.
  • the cutting device When using locks, closed at will, for the connecting of the tape ends, the cutting device, according to the invention, is combined with an interlocking device. This is the case if the locks are not provided with stopping devices automatically preventing the return movement of the tensioned tape, but when, for example, after the tensioning of the tape a pin securing the tape and/or tape ends must be pushed through the lock and the tape end or tape ends.
  • FIGS. l to 4 are elevational views of the tool showing the same in different stages of operation.
  • a tool body 1 is rigidly connected with a handle 2 which can be gripped together with a hand lever 4 supported at pivot 3 in the tool body.
  • a mounting is provided for a lock 6 which is adapted to connect the ends of a tape wrapped around a cable harness 7.
  • a condition to such procedure is that one tape end is already firmly connected with the lock 6 so that the tool must tension only the free tape end 8 drawn through the lock, must secure it in the lock and then cut the excess tape off.
  • the securing of the end of the tape in the lock is effected by means of a pin 9 provided at the lock. The pin is pushed through the lock 6 and the tape end 8 after the tensioning.
  • a known stopping device 10 for preventing return movement of the tape end 8 towards the lock 6.
  • the stopping device I0 is attached to a lever 40 pivotably connected to the tool body.
  • a similar stopping device It is mounted on the front end of a drawing bar I2, so that the free tape end can be easily inserted into both stopping devices.
  • the drawing bar 12 is movable in the longitudinal direction of the tool body and at the same time it is swivelably guided by means of a pin 13 attached to the drawing bar and engaged in a guide groove l4 in the body I.
  • the stopping device II is therefore pivotable about the pin III.
  • the rear end of the drawing bar l2 carries a bolt 15 which has the function of a glider, as will be explained later.
  • the pin may be rotatable to reduce contact friction.
  • rocker arm [8 has an edge 20 at the left of cutout 17 which extends roughly in the The direction of the drawing bar, the length of such edge 20 corresponding at least to the possible path of movement of this part of the rocker arm.
  • the rocker arm has an extension 21 against which a pressure spring 22 acts to move the rocker arm to the left in the drawing.
  • a tension spring 23 is attached to the rear end of the drawing bar 12, the other end of such tension spring 23 being firmly connected adjacent the lower end of the handle 2 to a device diagrammatically shown as an adjusting screw 24 serving to adjust the spring tension.
  • the spring 23 draws the bolt 15 into the edge cutout 17 of the rocker arm.
  • the spring tension, the direction of spring tension and the inclination of the flank 16 are so designed that the bolt is held in the edge cutout l7 until the desired tape tension has been reached, as will be shown later.
  • rocker arm 18 acts on a roll 26 on the hand lever 4. Movement of the hand lever in the direction of the arrow in FIG. 1 causes a corresponding movement of the rocker arm 18 to the right in the drawing and this also a corresponding movement of the drawing bar 12. Conversely, the spring 22 not only opposes movement of the rocker arm 18, but also urges the hand lever 4 back to the normal position of these parts (to the left in the drawing).
  • the movement of the drawing bar 12 to the right in the drawing is limited by a stop 27 rigidly attached to the tool body, which stop 27 engages the rear end 28 of the drawing bar.
  • the stop 27 is provided with flange 29 which prevents lifting of the drawing bar when the drawing bar is in contact with the stop so that the bolt 15 cannot lift from the edge cutout 17 when the drawing bar engages the stop 27.
  • the hand lever 4 has a frontwardly directed extension 30 which is provided with a pin 31 which is adapted to engage the rear end 32 of an arm 34 pivotably supported at 33 from the tool body.
  • the front end of arm 34 carries a cutting edge 35 and a punch 36 which are so arranged that on lifting of the front end of the arm 34, the punch 36 engages the pin 9 and pushes the same into the lock 6, while the cutting edge 35 then cuts off the free tape end behind the lock.
  • the lever 40 carries an abutment 41 on the surface facing the front of the tool.
  • the abutment 41 is adapted for being contacted by the front part of the arm 34.
  • peg or pin 42 On the drawing bar 12 is peg or pin 42 which cooperates with a spring 43 mounted on a bolt 44 firmly connected to the tool body such that the spring 43 pushes the drawing bar to its forward position, as shown in FIGS. I, 3 and 4.
  • the tool operates as follows:
  • the tape end 8 After the tape end 8 has been wrapped around the cable harness 7 and has been led through the lock 6, it is inserted into the tool front where it is gripped by the stopping devices and 11 (FIG. 1).
  • the hand lever 4 is moved in the direction of the arrow, as shown in FIG. 1, which causes the drawing bar to be pulled back from the tool front and the tape end held by the stopping device 11 is put under tension.
  • the lock 6 is in position in the support at the front of the tool during this tensioning process. The tensioning movement can be continued until the rear end of the drawing bar has reached the stop 27 (FIG. 2). Then the hand lever 4 is released and allowed to move in the direction of the arrow in FIG. 2, the tape under tension being held by the stopping device 10.
  • a tool for tensioning a tape wrapped around an object and for connecting the ends of the tape and cutting off the sur plus when a preset tension has been reached in in the tape comprising lock means for connecting the tape ends, a displaceable hand lever having a given range of travel, means for gripping and tensioning the tape, cutting means operatively associated with the hand lever for being operated when the tape tension exceeds a predetermined value to cut the tape, coupling means between said hand lever and the gripping and tensioning means and having an engaged state to cause tensioning of the tape as the hand lever is displaced, and having a disengaged state at a predetermined tension in the tape, and stop means to limit displacement of the hand lever to a restricted portion of the range of travel of the hand lever with the coupling mans in an engaged state said hand lever being operatively positioned to activate the lock means and thereafter the cutting means only when the hand lever is beyond the restricted portion of the range of travel after the coupling means is in disengaged state.
  • a tool as claimed in claim I comprising means for releasing the gripping and tensioning means after the ends of the tape have been connected and before operation of the cutting means whereby the tape ends are cut when not under tension.
  • said coupling means comprises an element with an inclined surface, a glide member engaging the inclined surface, and means applying the glide member against the inclined surface to prevent disengagement therefrom up to the predetermined tension in the tape.
  • a tool as claimed in claim 3, wherein said means applying the glide member against the inclined surface comprises spring means.
