Definitions

  • the invention relates to a hand tool for opening and closing clamping rings for barrels, the clamping rings each having a clamping lever which has a first lever side facing the inside of the clamping ring and an opposite second lever side facing away from the inside of the clamping ring, which lies between a closed position and an open position can be moved back and forth, wherein in particular the first lever side rests on the tension ring and / or the barrel in the closed position, and projects from the tension ring in the open position.
  • barrel is understood as a generic term for reclosable containers with a lid, the lid being locked on the barrel by means of the clamping ring, provided that the clamping ring is in the closed position.
  • Such barrels are used in many industrial sectors, for example in the food industry and the process engineering or chemical industry. They are used to store raw materials and intermediate products from various manufacturing processes. It is therefore important that the barrels, which are also referred to as containers or packaging, can be opened and closed quickly and with a few simple steps.
  • clamping rings have been found in the prior art for this purpose established for locking barrel lids on the barrels.
  • the invention was therefore based on the object of specifying a hand tool for opening and closing clamping rings which largely overcomes the disadvantages described above.
  • the invention was based on the object of specifying a hand tool which enables the clamping ring to be opened and closed in a few simple steps and reliably protects the operator from injuries.
  • the invention achieves the object on which it is based in a hand tool of the type described at the outset, in that the hand tool has a base body which has a first end section and a second end section which is arranged opposite the first end section and which has a recess on the first end section for attaching the hand tool on the tensioning lever, and for applying a leverage to the tensioning lever both in the direction of the open position and in the direction of the closed position.
  • the invention makes use of the knowledge that the same type of engagement between hand tool and clamping lever is used to move the clamping lever both in the direction of the open position and in the direction of the closed position.
  • the hand tool with its recess is placed on the clamping lever and the recess is designed such that a leverage effect can be applied in the direction of the open position and in the direction of the closed position, direct contact with the clamping lever with the hands is no longer necessary.
  • a lever extension based on the size of the tensioning lever is also achieved by means of the base body, so that the manual forces to be applied are significantly reduced compared to a purely manual operation of the tensioning lever. This also reduces the influence of product tolerances on the side of the drum and clamping ring; the hand tool attached to the clamping lever makes it possible to transmit sufficient leverage to the clamping lever.
  • the recess has an inner wall and is designed to enclose the tensioning lever in the plugged-on state in such a way that the first and second lever sides of the tensioning lever are in contact with the inner wall. It is entirely permissible here for there to be a certain amount of play between the recess and the clamping lever.
  • the recess and with it the inner wall are dimensioned such that when the hand tool is fully attached, a pivoting movement of the hand tool does not cause the tensioning lever to slide out of the recess, but at the latest when the lever force is applied to the hand tool of the tension lever both on the inner wall supports the first and second lever side.
  • the recess has an insertion opening in an end face of the first end section and a slot which extends from the end face of the first end section in the direction of the second end section.
  • the slot is preferably dimensioned in such a way that the clamping ring can extend through the slot.
  • the width of the slot is preferably chosen so that clamping rings of several sizes of clamping ring fit into the slot. Because the clamping ring can extend through the slot, the hand tool can be placed much more easily on the clamping lever when it is in the closed position.
  • the hand tool is guided on the clamping lever along the clamping ring by means of the slot, and the two edges on the end face of the first end section, from which the slot extends, can slide along the clamping ring under the clamping lever.
  • the recess in the base body extends from a first end section to the second end section.
  • the recess in the base body extends from a first end section to the second end section.
  • the recess did not extend completely through to the first end section through the base body.
  • the increased depth of the recess according to this embodiment which is particularly preferred as a through opening is considered advantageous in terms of increased flexibility for different clamping lever lengths.
  • this design of the recess saves weight of the hand tool.
  • a wedge bevel is formed on a, preferably outer, circumferential side of the base body and extends towards the first end face at the first end section.
  • the wedge bevel is preferably formed on the side of the hand tool on which the slot is formed.
  • the wedge bevel reduces the wall thickness of the base body at the insertion opening, making it easier to attach the hand tool to the lever. If the wedge bevel is arranged on the circumferential side of the slot, the edges arranged on both sides of the slot are, as it were, pointed at the insertion opening, so that the hand tool can be moved particularly easily under the clamping lever.
  • the base body is angled somewhat further from the tensioning ring when the tensioning lever is attached, in particular in its closed position, which facilitates operation.
  • the wedge bevel is accordingly formed on both sides of the slot.
  • the base body of the hand tool has an outer peripheral surface, and the wedge bevel is formed on the outer peripheral surface.
  • the base body of the hand tool preferably extends along a longitudinal axis and has one of the following cross-sectional shapes perpendicular to the longitudinal axis: oval, circular, elliptical, polygonal, or a combination of several of these shapes.
  • the base body has a grip section, preferably a grip section that can be gripped with one hand.
  • the grip section is preferably arranged between the first and the second end section and particularly preferably roughened, for example knurled. The roughening prevents the risk of an unwanted slipping or losing the hand tool during operation. It also helps to visually identify the handle section and facilitates intuitive operation.
  • At least one projection is formed on the second end section, which is designed to be driven into a gap between the barrel and its barrel cover in order to open the barrel.
  • the hand tool has two or more such projections.
  • the projection or the projections each have a straight blade tip.
  • the projections are thus essentially designed like the blade tips of pointed screwdrivers and, like these, can be used in a multifunctional manner.
  • the or the projections are preferably hardened, and particularly preferably tempered.
  • the base body of the hand tool consists of a metal alloy that is free of aluminum or has an aluminum content of less than 10 percent by weight.
  • the metal alloy is free of magnesium or has a magnesium content of in any case less than 10 percent by weight. Dispensing with or largely dispensing with aluminum and magnesium as an alloy component reduces the risk of sparking when the hand tool is struck or rubbed. This enables the hand tool to also be used in explosion-proof areas.
  • the metal alloy has a chromium content of more than 10.5 percent by weight.
  • the metal alloy formed in this way is thus a stainless steel alloy or a stainless chromium-nickel alloy, which differs from the steel alloys in that the iron content drops below 50 percent by weight.
  • the invention has been described above with reference to the hand tool according to the invention.
  • the invention further relates to the use of a hand tool according to one of the preferred embodiments described above for opening and closing clamping rings for barrels.
  • the use here makes use of the same advantages and preferred embodiments as the hand tool according to the invention, so that reference is made to the above statements in order to avoid repetitions.
  • the invention relates to a barrel system which has a barrel lid for closing the barrel and a tensioning ring for locking the barrel lid to the barrel, the tensioning ring having a tensioning lever which has a first lever side facing the interior of the tensioning ring and an opposite side of has the second lever side facing away from the inside of the clamping ring, which can be moved back and forth between a closed position and an open position, in particular the first lever side abutting the clamping ring and / or the barrel in the closed position and projecting from the clamping ring in the open position.

  • a recess 11 is made, which in the present exemplary embodiment extends as a through hole completely through the base body 3 to the second end section 7.
  • the recess 11 opens into an insertion opening 15 on an end face 22 of the first end section 5 ( Figure 2 ).
  • the recess 11 has an inner wall 20 with which the tensioning lever comes into contact when it is plugged on (cf. Figure 4 ).
  • the recess 11 is opened towards the circumference of the base body 3 by means of a slot 13 which extends from the insertion opening 15 in the direction of the second end section 7.
  • the base body 3 has a circumferential side 4 which is tapered toward the first end section 5.
  • the taper is achieved by means of a wedge bevel 19 formed on one side.
  • the slot 13 is preferably formed in the wedge bevel 19.
  • edges 17a, 17b are formed on both sides of the slot 13, which preferably taper to a point due to the wedge bevel 19.
  • the second end section 7 arranged opposite the first end section 5 has two projections 21a, b which extend from an end face 24 of the second end section 7 (cf. Figure 2 ) protrude from.
  • the projections 21a, b each have a straight blade tip 23.
  • the projections 21a, 21b are preferably designed to be used like a chisel or screwdriver and / or to be used to pry open container lids.
  • the hand tool according to Figure 1 is in Figure 2 shown in two side views.
  • the hand tool 1 has a length L 1 in a range from 160 mm to 260 mm from the first end face 22 in the first end section 5 to the second end face 24 in the second end section 7. This length range represents optimal usability with one or two hands.
