Abstract
The installation tool is especially suitable for attaching binding means which require to be tightened and cut off. A tightening mechanism (11) is actuated by means of a toggle joint (14) which gives way when a predetermined degree of tightening is reached and then actuates a cutting lever (12). The binding means is thus cut through with reduced impact action. In addition, the tool is easy to actuate. The degree of tightening can be set accurately and reliably, and the binding material is delivered from the tool to a controllable extent. <IMAGE>
Description
(54) TENSIONING AND SEVERING TOOLS
(71) We, DENNISON MANUFAC
TURING CO. LIMITED, a Company registered under the laws of England, of
Colonial Way, Watford, Hertfordshire. do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:
This invention relates to a tensioning and severing tool and more particularly but not exclusively to a tool for the installation of fasteners such as cable ties.
According to the present invention. a tensioning and severing tool comprises a gripper for an article to be tensioned. a drive member, a transmission between the drive member and the gripper including a toggle linkage arranged so that the linkage is in compression during tensioning, a spring holding the linkage in an almost straight condition until a predetermined tensioning force is applied by the drive member through the toggle linkage to the gripper, and a sever mechanism operable by collapse of the toggle linkage to sever the article.
Preferably, the tool includes a housing and a slide member slidable in the housing, the gripper being mounted at one end of the slide member and one of the toggle links being pivoted to the other end of the slide member. The other toggle link may be pivoted to one end of a lever constituting the drive member. the other end of the lever being pivoted to the housing. Preferably, the spring applies a force through a bar which is connected to the knuckle joint of the toggle.
The invention may be carried into practice in various wavs but one tensioning and severing tool embodying the invention will now be described by wav of example with reference to the accompanying drawings. in which:
Figure 1 is a perspective view of the tool being used in the installation of a cable tie;

Figure 4A.
Turning to the drawings. there is shown a tensioning and severing tool 10 formed by split-cover housing 10h containing a tensioning assemblage 11 and a pivoted cut-off lever 12, which is visible through a viewing aperture of a cutter guard 12g and mounts a cutter blade 12b.
As illustrated in Figure 1, the tool 10 can be used to complete the installation of an item such as a cable tie 20. The strap portion 21 of the tie 20 is wrapped around articles that are to be bundled. for example the individual wires W of a cable C. A free end 22 of the tie 20 is inserted through the head 23 of the strap into the mouth of the tool 10 between gripper constituents lip and Ila of the tensioning assemblage 11.
When force F1 is applied to a trigger i3 of the tool 10. it is transmitted through levers and linkages (not visible in Figure 1) to the tensioning assemblage l l. causing the assemblage to be drawn towards the rear of the gun. This frees a pivoted and springloaded pawl lip which rotates against the portion 22 of the strap and grips it with respect to a stud Ila.
The initial rearward motion of the tensioning assemblage 11 caused by the force F, tightens the portion 21 of the strap around the wires W of the cable C, with the head 23 of the cable tie 2() in close abutment with the tool 10. Further movement of the tensioning assemblage 11 increases the tension applied to the gripped portion 22 of the tie 20 until a predetermined tension level is reached. At that point, as explained below, the force transmitted to the tensioning assemblage 11 from the trigger 13 causes a collapse of the intervening linkage which acts upon the cutoff lever 12 and pivots it upwardly, bringing the blade 12b into sever position with respect to the gripped end portion 22 of the cable tie 20.
In the operation of a typical tensioning and severing tool previously available, the sever action produces a significant shock impact. However, this impact is significantly reduced to in the tool being described because of the particular way in which the cutoff lever 12 is operated as explained in conjunction with Figures 2A to 2C.
A perspective view showing the relationship between the tensioning assemblage 11 and the cutoff lever 12 is given in Figure 2A.
The tensioning assemblage 11 is maintained in a normally forward position in the tool 10 by a compression spring tIc. The tensioning assemblage is connected to the trigger 13 through a set of actuator linkages including toggle linkages 14 and an internal actuator lever 15.
When the trigger force Ft is applied, it is transmitted through a trigger link 13t to the actuator lever 15 which is pivotally mounted within the handle 16 of the tool 10. The upper portion of the actuator lever 15 is pivotally connected to the toggle linkages 14, which are, in turn. pivotally connected to the bar 1 lib of the tensioning assemblage 11.To maintain the toggle linkages 14 in position to transmit the trigger force F,* a countervailing force Fe is applied to the midpoint l4tt7of the toggle through a toggle arm 14(1 The toggle is never completelv straight: there is always a slight angular inclination. in the rest position. towards the force Fe. When the tensioning force applied from the trigger 13 exceeds the countervailing force Fe. the toggle collapses by pivoting with respect to both the actuator lever 15 and the tensioning bar l lb and engages a cam surface 12c of the cutoff lever 12.Since the operation of the cutoff lever takes place while the actuator lever is moving to the rear. there is. in effect. a cushioned impact of the collapsed toggle linkages 14 against the cutoff lever 12. It is believed that this cushioning limits the shock loading that is produced when the strap 22 is severed.
In addition, an ejector spring 17, in the form of a leaf 17f with a curved end portion 17c extending into the mouth of the tool, is included to reduce any tendency for the severed end of the strap to be propelled toward the user.
As the tensioning bar tib is drawn towards the rear of the gun 10, the curved portion 17c of the ejector spring 17 tends to be flattened against the adjoining housing wall. When the pawl lip reaches a cam surface lic (shown in Figures 1 and 2A), with the strap 22 under tension, the cam acts upon the pawl and partially releases it. In addition, as noted in Figure 1. the housing 10h has a shield 10s that extends at the top of the gun to the vicinity of the ejector spring 17. Consequently when the strap is under tension, with the pawl lip partially released and the spring 17 partially deflected, and the cutter blade 12b is operated to sever the strap, the severed portion tends to be propelled laterally out of the housing, instead of towards the user.The desired lateral propulsion is promoted by contributions from the shield 10s. the partial pawl release pivoted by the cam tic and the ejector spring 17.
A schematic representation of the tensioning and sever operation is illustrated in
Figures 2B and 2C. initially as shown in
Figure 2B the individual links of the toggle assemblage 14 are almost in alignment but with a slight inclination downwards. For simplicity the toggle assemblage 14 in Figure 2B is shown formed bv the first line 14-1 that is pivotally connected to the tensioning bar lib and a second link 14-2 that is pivotally connected to the actuator lever 15. This actuator and sever links 14-1 and 14-2 are in turn pivotally joined. It is at this point of joinder 14m that the countervailing force Fe is applied.To keep the countervailing force from driving the links 14-l and 14-2 of the toggle assemblage out of alignment. the tensioning bar lib includes an integral stop lit shown in Figure 2B. A possible alternative is shown in Figure 4A where the upward motion of the linkages is limited by a slot 1 is in the draw bar lib. The various wavs of applying the countervailing force Foe to the toggle assemblage 14 are discussed below.
When the tension applied to the strap by the bar I Ib exceeds the value of the countervailine force F, applied at the pivot centre 14m of the toggle assemblage 14. the toggle collapses as shown in Figure 2C. This collapse brings the bearing surface 14b of the toggle into engagement with the cam surface 12c at the rear of the cutoff lever 12.
Since the toggle assemblage 14 is formed by pivotally connected members. the force transmitted to the cutoff lever is composed of both horizontal and vertical components, by which a cushioned impact is applied to the cutoff lever 12, instead of a direct impact, so that impact shock loading is avoided.
In addition, as is evident from Figure 2B, the use of the trigger 13 in conjunction with the actuator lever 15 provides a mechanical advantage so that the amount of operator force applied to the toggle is considerably less than that needed with conventonal installation tools. The use of the actuator lever 15 also permits the desired tensioning force to be applied by movement over a relatively small arc of operation of the trigger 13.
The desired countervailing force Fe is provided by a compression spring 32s in a cage 30 shown in Figures 3A and 3B. As indicated in Figure 3A the end of the toggle linkage 14a is connected by a pivot pin 31p to the lower end of a cover part 31 of the cage 30, which is slideably movable with respect to a housing part 32 of the cage within which the spring 32s is located.One end of the spring abuts the bottom wall of the housing while the top end abuts a lug 31p which projects from the upper end of the cover part 31 into the housing part 32. A possible alternative to the compression spring 32s and cage 30 is a tension spring one end of which is hooked to the end of the link 14a and the other end of which is hooked to the body of the tool near the top of the link 14a but such a spring tends to be mechanicallv unreliable.
To adjust the tension applied through the toggle arm 14a an adjusting member 32a is threaded into the bottom portion 32 of the cage 30 as shown in Figure 3B by rotation of a tenson control knob 33. This moves the lower portion 32 of the cage 30 of Figure 3A upwardly with respect to the upper portion 31 and carries with it the indicator 32r that moves within a slot 31s of the cover portion 31 and simultaneously causes compression of the tension control spring 32s. This arrangement achieves precise control over tension and a high degree of mechanical stability.
A partial sectional view of the entire installation tool of Figure 1 is shown in
Figures 4A to 4C to indicate the relative positioning of the internal constituents of the tool. as well as the interralations among those constituents.
Thus in the tool 1() as shown in Figures 4A and 4B the toggle assemblage 14 is formed bv four links (Figure 4C) 14-1 to 14-4. The link 14-1 is seated on a hub l Ili of the tensioning bar ill?. The link 14-l is in turn pivotally connected to the arm 14a that extends to the compression cage 3(). the arm 14a is connected to the lever 15 bv the link 14-2. as well as bv the further fink 14-3.
There is also pivotal connection between the hub ith of the tensioning bar 11b and the arm 14a by the link 14-4. It is the latter link that limits the upward movement of the toggle assemblage due to the application of the compression force Fe through the arm 14a. This is because the fourth linkage 14-4 rides in the slot 11s of the tensioning bar 11b.Initially with the full compression force Fe applied to the arm 14a the individual links of the toggle assemblage are almost in alignment and the link 14-4 is seated in the upper part of the recess 1 Is. When the tension applied to the strap exceeds the countervailing force Fe the toggle assemblage collapses as described previously and the link 14-4 moves out of the slot 11s to contact the cam surface 12c and operate the sever lever 12.
Also indicated in Figures 4A and 4B is the placement of the cam 11c that provides partial release of the pawl 1 lip before sever.
Details of the compression cage 30 are illustrated in Figures 4A and 4C.
