Definitions

the present invention relates to a portable rivetting machine of the type comprising a channel, defined by a base wall and a pair of side walls, for slidingly receiving a series of interconnected rivet elements (rivets, U-shaped staples and the like), a resiliently-loaded slidable pusher for pushing the series of elements towards a discharge end of the channel where there is a slit for the discharge of the elements from the bottom of the channel, and a blade-shaped punch reciprocably movable through the slit to detach the elements one by one from the series and discharge them through the slit itself.
a portable rivetting machine of the type comprising a channel, defined by a base wall and a pair of side walls, for slidingly receiving a series of interconnected rivet elements (rivets, U-shaped staples and the like), a resiliently-loaded slidable pusher for pushing the series of elements towards a discharge end of the channel where there is a slit for the discharge of the elements from the bottom of the channel, and
Portable rivetting machines of this type are already known which for the most part operate electromagnetically or pneumatically, the channel of these machines being arranged to receive selectively a series of rivets and a series of U-shaped staples of a given size.
the channel is constituted by a substantially U-shaped element the width of which is such as to guide the series of metal staples.
the bottom of the latter has a deep groove for guiding the series of rivets.
the main object of the present invention is to provide a more versatile rivetting machine, which is able to receive selectively, in addition to a series of rivets, more than one series of U-shaped staples of a different width and height.
this object is achieved by means of a rivetting machine of the type mentioned at the beginning, characterised in that the channel is internally provided with more than one pair of longitudinal dividing walls extending up from its base wall such as to define pairs of interstices disposed symmetrically with respect to the centre of the channel as well as a central interstice extending along the centre line of the channel, each pair of two symmetrically-disposed interstices being arranged to receive the legs of a respective series of U-shaped staples of a width corresponding to the distance between the interstices themselves, and the central space being arranged to receive a series of rivets, and in that the pusher comprises the same number of parallel blades as the number of interstices with each blade being housed in an interstice itself, the blades being interconnected by a yoke above the upper edges of the dividing walls of the channel.
a rivetting machine comprises, in known manner, a body 10 with a base part 12, a part 14 acting as a handgrip and a head 16.
a head 16 In the head 16 is housed, in known manner, an electromagnet which can be selectively energised by means of a trigger 18 to cause a blade punch for discharging staples from the machine, to descend.
a sheet-metal channel 20 which accommodates a series of rivet elements. As will be seen below, these elements are urged towards the end of the channel 20 underlying the head 16 where the blade punch discharges them one by one through a slit defined by a pair of mating plates 22 and 24 of which more will be said below.
a slidable foot 26 is connected to the channel 20 for supporting the rivetting machine on the working surface P.
the channel 20 includes an outer sheet-metal element 28 of substantially U-shaped profile, with side walls 30 and a base well 32. Within the outer element 28 there is located a further U-shaped, sheet-metal element 34 which has a base wall 36 applied to the wall 32, and two side walls 38.
the walls 38 and strips 40 define respective pairs of longitudinal dividing walls which extend up from the base wall of the channel and which define a pair of outermost interstices 50 (between the walls 30 and the walls 38), a pair of innermost interstices 52 (between the dividing walls 38 and 40), as well as a central space 54 (between the dividing walls 40).
the dividing walls 38 are higher than the dividing walls 40.
a pusher 56 is slidable in the channel 20 and comprises an outer sheet-metal element 58 in the form of an upturned U with a pair of sides 60 and an upper yoke 62.
An internal sheet-metal element 64 is located within the outer element 58 and has an upturned U profile with a pair of side walls 66 and an upper yoke 67.
a plate element 68 which has tabs 70 on its upper edge.
the tabs are inserted in respective slits 72 in the internal U-shaped element 64 and slits 74 in the outer U-shaped element 58, and are upset to secure the three elements 62, 64, 68 together in the configuration illustrated in Figure 5.
the walls 60, 66 and 68 define respective blades each of which is housed in one of the interstices of the channel 20. As will be understood below, these blades serve to engage the rear end of the respective series of rivet elements and push them towards the discharge end of the channel 20.
a pair of lugs 76 Projecting from the upper yoke 62 of the outer U -shaped element 58 is a pair of lugs 76 through which a longitudinal guide rod 78 can slide.
a hook member 80 of shaped sheet-metal is fixed to the rear end of the rod 78 and can be hooked, in known manner, to the entry end of the channel 20.
a helical spring 82 is interposed between the pusher 56 and the hook member 80 for the purpose of resiliently urging a series of staples along the channel 20 by means of the blades of the pusher 56.
An appendage 84 in the form of a plaque bearing a reference mark 86 is mounted on the rod 78 between the lugs 76.
the plaque 84 projects through a slot between the channel 20 and the base part 12 of the body 10 and is movable along a scale 88 ( Figure 1 ) to indicate the position of the pusher 58 in the channel 20 and hence the quantity of rivet elements contained in the channel itself.
the side walls 30 of the channel have respective longitudinal ribs 90 which define corresponding internal grooves 92. In these grooves 92 are guided corresponding longitudinal ribs 94 of the pusher 56, This coupling has the object of preventing the pusher 56 from inclining with respect to its direction of sliding, since inclination of the pusher could cause the rivet elements to jam, especially the last element to be discharged.
the foot 26 is constituted by a substantially U-shaped sheet-metal element. In the upper part of its side wall, it has respective stepped wings 96 which embrace the ribs 90. Tabs 97 are formed in the wings 96 by semi-punching and engage the upper parts of the ribs 90. In this manner, the foot 26 is mounted for sliding movement along the channel 20.
the foot 26 has a front projecting part 98 which, when the foot is in its fully advanced position, is disposed beneath the plates 22, 24 and closes off the discharge slit to provide a safety barrier in periods when the rivetting machine is not in use.
the foot 26 can be fixed in this advanced position by means of a side screw 99 ( Figure 5) which can be screwed into one of the side walls of the channel 20 through a corresponding hole in the foot 26, one of the ends of which, moreover, is arranged to be in front of the pusher 56 to prevent its advancement.
a first type of rivetting element is shown as E 1 and is constituted by a relatively wide, short staple.
the transverse or yoke part of the element E 1 rests on the upper edges of the outermost pair of dividing walls 38 and the legs of the element E 1 are located in the outermost interstices 50 and slidingly embrace the dividing walls 38.
the pusher 20 ( Figure 5) pushes the series of elements E 1 by means of its outermost blades or sides 60.
FIG 7 a second type of rivet element E 2 which is relatively narrow and long.
the points or lower ends of the legs of the element E 2 rest on the base wall of the channel or rather on the base wall 36 of the innermost U-shaped element, and these legs are guided in the interstices 52 between the two pairs of dividing walls 38 and 40.
the pusher 56 ( Figure 5) pushes the series of elements E 2 by means of its pair of blades 66.
FIG 8 a further rivet element E 3 constituted by a rivet.
the point of the rivet rests on the base wall 36 and is guided within the central interstice 54 by means of the two dividing walls 40.
the pusher ( Figure 5) pushes the series of rivets by means of its middle blade 68.
the discharge slit at the end of the channel 20 through which the blade punch of the rivetting machine expels the rivet elements one by one is indicated by 100.
the slit 100 is defined between two mating plates, a front plate 22 and a rear plate 24.
the front plate 22 is formed with a wide groove 102 of a width such as to guide the rivet element E 1 as well as the blade punch (not shown).
the front plate 22 is also formed with a narrow central guide groove 104 for the rivet element or rivet E 3 .
the rear plate 24 is formed with a groove 106 of intermediate width which serves as a guide for the rivet element E 2 .
