Definitions

  • the invention relates to a dispenser for blades, which has a housing for receiving a stack or package of blades, which contains a slot at one end for pushing out the top blade of the blade package.
  • the housing serves solely as a container for storing the blades, from which the blades can be pushed out by hand if necessary and then used, for example, in a separate holder in order to be able to carry out special work with the blade, in particular cutting work .
  • the invention has for its object to design the housing of a blade dispenser such that it is not only suitable as a container for storing and removing unused blades, but also for other uses, for example as a holder for a blade partially ejected from it can serve so that the dispenser can also be used as a holder for a kind of auxiliary knife.
  • the invention provides a blade dispenser which is not only suitable for storing and dispensing unused blades, but which can also be used as a holder for a blade which is only partially ejected from it, so that it is a combination of blade dispenser and knife or auxiliary knife forms.
  • the dispenser or its housing is designed so that it ensures complete protection of the user when removing individual blades and also when working with a blade that is only partially ejected.
  • a blade When a blade is pushed out normally, all edges of the blade to be pushed out, including the ground edge, are enclosed by parts of the housing until the user pulls out the partially extended blade and then inserts it, for example, in a separate holder. If the dispenser is used as a holder for a partially extended blade, the top blade of the stack of blades is extended so far that a short piece of its cutting edge is exposed for the desired cutting work or protrudes beyond the housing.
  • the rear end of the dispenser housing is preferably rounded, so that the housing is adapted to the handle of a knife such as a kitchen knife and lies well in the hand of the user.
  • the cover of the housing is preferably formed in one piece with the body thereof and injection molded in plastic, the connection between the body and the cover being formed by a film hinge.
  • the lid After inserting a compression spring and a blade package into the open housing, the lid is folded onto the body and closed by barbs provided on its free edge, which can snap into corresponding openings in the body. No separate components are therefore required.
  • This closure is permanent and does not open by itself, but is secured against unintentional opening.
  • the housing can therefore be disposed of inexpensively after all the blades have been removed from it, especially if the spring arranged in it consists of the same or the same material as the housing itself.
  • a slide is mounted in the cover of the housing, which interacts with the uppermost blade of the blade package located in the housing in order to push it out and, if necessary, to advance and hold it in a working position.
  • the slide In this last-mentioned position, the slide must be held by pressure exerted on it, since otherwise the blade, which is pushed out into a working position, is pushed back into the dispenser housing by slight pressure. This forms an effective protection for the user against injuries. Since the blade pushed out into the working position slides back into the dispenser housing under cutting load when the user does not press and hold the slide, the blade slides back into the housing even if the dispenser falls down, for example, and the tip of the top blade is pushed out strikes a more or less solid object.
  • the upstanding webs or boundaries of the housing provided for lateral edge protection of the pushed-out blades are preferably at least partially sloping outwards or beveled in order to be able to better grasp the ends of the blades advanced between these webs, for example by pointing at the extended blade end with the Presses your finger or your thumb and then pulls the blade thus captured out of the housing.
  • Known bayonet rivets can be provided for fastening the blade dispenser according to the invention to a display card or other base, which rivets can be inserted into corresponding holes in the housing of the dispenser and can be latched therein.
  • the blade dispenser shown in the drawing has a housing 1 in the form of a handle, which consists of a box-shaped body 2 and a lid 3 closing this body.
  • the lid 3 is connected to the body 2 at one longitudinal edge via a film hinge 4, so that the body 2 and lid 3 can be injection-molded in one piece in plastic.
  • the cover 3 is held in the closed position by barbs 5 which snap into slot-shaped recesses 6 in the relevant side wall 7 of the body 2 of the housing 1, so that this closure cannot be released without the action of a tool.
  • each barb 5 formed on the cover 3 has a conical body 35 with a protruding nose 34 formed thereon.
  • the barbs 5 can be inserted with play into the corresponding recess 6 in such a way that the conical body 35 allows the barb 5 to deflect and the nose 34 then lies from the outside against a recess 36 located within the recess 6 such that the Barb 5 practically does not protrude beyond the outside of the side wall 7 of the body 2 of the housing 1.
  • a raised web 9 is integrally formed on the bottom 8 of the body 2, which delimits a space 10 in which an arched leaf spring, not shown here, can be inserted, which contains a package 11 inserted into the housing 1, which consists of a A plurality of, for example, trapezoidal, but also differently shaped, blades 12, presses against the cover 3.
  • the lid 3 is on the inside with provided in the longitudinal direction of the same extending ribs 13 and 14, which serve as an attachment for the blade package 11, as shown in particular in FIG. 2.
  • the inner ribs 14 are inclined relative to one another and form a dovetail guide 15, as can be seen in FIGS. 2 and 4.
  • the cover 3 contains an elongated hole 16 extending in the longitudinal direction thereof, which serves as a guide and end position limitation for a slide 17, the details of which can best be seen from FIGS. 5 and 6.
  • the mutually inclined two inner ribs 14 are arranged on both sides of the elongated hole 16.
  • the slide 17 has two integrally connected sections, namely a pressure piece 18 located on the outside of the cover 3 and a driver 19 guided on the inside of the cover 3 in the dovetail guide 15, both of which are wider than the elongated hole 16 and over a web-shaped neck 20, which is adapted to the width of the elongated hole 16, are integrally connected to one another.
  • the slide 17 can be inserted into the elongated hole 16 and the dovetail guide 15 by suitable tilting movements such that it is and remains captively connected to the cover 3.
  • the slide 17 is injection molded in one piece from plastic, which has a certain elasticity, it is possible to pivot the pressure piece 18 relative to the driver 19 around the neck 20, which in this case forms a type of joint.
  • the driver 19 has on its underside a shoulder 21 which serves as a stop and can be pressed against the rear edge of the uppermost blade 12 of the blade package 11 in order to remove this blade from the housing 1 through a slot located at the front end thereof 22 push out.
  • the pressure piece 18 has near its front end on the underside a web 23 which can lie as a limit stop against the front end 24 of the elongated hole 16 in order to limit the distance by which the topmost blade 12 of the package 11 through the slot 22 can be pushed out onto a support 25 adjoining the slot 22.
  • This support 25 is designed so that the end of a partially extended blade 12 lying on it, for example, between the thumb and a finger of a user can be gripped and pulled out of the housing 1.
  • the front edge 26 of the support 25 is beveled in accordance with the front edge 27 of trapezoidal blades 12, for example accommodated in the housing 1, so that this front edge 27 does not protrude beyond the front edge 26 of the supports 25 when the blade 12 is pushed out normally, in order to injure the user to avoid.
  • a raised web 28 tapering towards the front edge 26 is provided as edge protection for the blades 12 to be pushed out.
  • an arch-shaped, cross-sectionally U-shaped extension 29 is provided on the cover 3, which serves as a three-sided edge protection for the ground edge of the blade 12 to be pushed out and is arranged with its top over this blade.
  • lateral webs 30 are provided which also taper in a wedge shape towards the front edge 26 of the support 25 in order to facilitate gripping the front end of a partially extended blade 12 between the thumb and fingers of a user.
  • the end 31 of the housing 1 opposite the slot 22 is rounded in a semicircular shape, as shown in FIG. 1, so that the housing 1, when it serves as a handle for an auxiliary knife, lies well in the hand of the user.
  • the top blade 12 of the blade package 11 is included its front end only pushed so far onto the support 25 that the front edge 27 of the blade 12 is in the region of the front edge 26 of the support 25 and does not protrude beyond it.
  • the housing 1 is to be used as a holder for an auxiliary knife or for a blade 12 to be brought into a cutting position, it is necessary to slide the blade in question so far out of the housing 1 that it passes over the front edge 26 of the support 25 protrudes a short piece to enable the desired cutting effect. It is also necessary to keep the extended blade 12 in the desired working position.
  • the pressure piece 18 of the slide 17 is provided at the rear end with an angled upstanding extension 32, which makes it possible to pivot the pressure piece 18 around the neck 20 relative to the driver 19 held in the dovetail guide 15 in such a way that the web 23 is raised above the front end 24 of the elongated hole 16 and, accordingly, the slider 17 can be advanced further until the web-shaped neck 20 of the slider 17 lies against the front end 24 of the elongated hole 16 in a stop shape. Now the extended blade 12 is in a working position in which it can develop a cutting effect.
  • the web 28 serves as an abutment, so that the blade 12 is held sufficiently firmly in the cutting direction by the housing 1 serving as a holder, as long as it is held in the extended position by sufficient pressure on the pressure piece 18 and in particular its extension 32. However, if the pressure on the pressure piece 18 and its extension 32 is released, the blade 12 is no longer held in its extended position, so that it slides back into the housing 1 under cutting pressure or other external pressure exerted on it until it no longer has the Front edge 26 of the pad 25 protrudes.
  • the blade 12 can therefore not cause injuries or other harmful effects. Rather, it is arranged within the housing 1 in the partially extended position, from which it can also be removed by hand.
  • bayonet holes 33 for inserting bayonet rivets, not shown here, with which the housing 1 can be attached to a display card, not shown.
