Definitions

  • the invention relates to a trowel with a handle a sheet and attached holder for the Handle according to the preamble of claim 1.
  • Such a trowel is known in the prior art.
  • the US patent is only given as an example 5,446,941 or 5,522,111.
  • the fastening section sets progress in a spacing section.
  • smoothing trowel is the Fastening section than essentially over the rib extending over the entire length of the leaf.
  • the spacing section protrudes approximately at right angles from the mounting section.
  • the handle is attached, which is about extends parallel to the rib.
  • the handle is by means of an insertion section connected to the bracket.
  • the insertion section is as in the prior art rod protruding in the longitudinal direction formed which with an end nut Handle is attached.
  • the insertion section protrudes approximately perpendicular to the spacing section.
  • a smoothing trowel is known from GM 18 75 730, where a hinge penetrates a handle.
  • a Similar smoothing trowel is known from DE 35 40 565 A1.
  • a hinge also penetrates the handle there. in the A push-on neck sits with the forehead area of the handle laterally protruding wings for thumb support.
  • the invention is based on the task, a generic Trowel with the measures taken advantages of use achieved in the prior art to ensure easier assembly and manufacture.
  • the embodiment of the invention is a Given a trowel, in which the handle without the conventional, Angel running in the longitudinal direction of the handle the trowel is connected. It is an aspect of the invention that the insertion section in a radial opening of the handle. The handle is now no longer by sliding it in its longitudinal direction on a Angel connected to the bracket but by one Push in the radial direction onto the insertion section the bracket. The insertion section can by a axially inserted locking pin against the handle Pull out be secured. It is beneficial if the insertion section in its insertion direction rejuvenated. If the insertion section conforms to According to the radial recess, the Taper a wedge effect, which is a backlash Holder of the handle on the insertion section comes towards.
  • the handle is advantageously made of a plastic sprayed.
  • the core, the injection mold which in the radial recess can be the shape of the Own insertion section. Due to the production-related low shrinkage of the plastic material then a tight fit of the insertion section in the Insert opening (radial recess) guaranteed.
  • the insertion section an essentially linear extension of the spacing section. This variant is particularly advantageous for trowels.
  • the insertion section can have a rounded end. This is advantageous in terms of injection molding. But it also brings Advantages in the production of the over the conventional long fishing stub-like insertion section, which extends into the handle beyond the center of the handle extends.
  • the insertion section can have a pyramid shape have.
  • the locking pin by means of which the Insertion section in the form-fitting radial recess is held, can be designed as a countersunk screw be screwed into the handle on the front is and penetrates an opening of the insertion portion.
  • the thread of the Sennkopfscrew cuts thereby into the massive handle volume.
  • a preferred one Design is made of a hard plastic existing handle body with a soft plastic jacket overdrawn. It is advantageous if the front side of the handle into which the countersunk screw is screwed is made of hard plastic material.
  • the invention also includes a handle for a Trowel or the like.
  • the handle has in the area of his Radial opening for inserting a front Insertion section of a fastening section or the like.
  • the handle preferably consists of a Hard plastic core, which is preferably a hollow body trains.
  • This hollow body can consist of two semi-hollow ones Core parts be assembled.
  • the two half-height Core parts form a when plugged together Parting line.
  • This parting line is the soft plastic jacket covered.
  • Put the two core parts together the edges of the core parts are narrower designed so that an overlap zone is formed.
  • the two core parts engage in this overlap zone together.
  • On the outside of the core part webs are arranged, the height of the thickness of the soft plastic coating corresponds.
  • the put together Hard plastic core can with a gap spacing placed in an injection mold and centered, whereby the web is supported on the mold nest. In these The soft plastic is then injected into the gap, so that the end faces of the webs with the soft plastic jacket exposed to the outside in alignment.
  • the insertion section 5 has one truncated pyramid shape. It tapers in the direction of insertion and has a rounded end edge 14.
  • the handle consists essentially of one circular cylindrical plastic body, the has a solid hard core 10 which of is surrounded by a soft plastic jacket 9. In the area the insertion opening 6, the hard core 10 extends to the Grip surface.
  • the insertion opening 6 extends up to the imaginary longitudinal central axis of the handle and has a distance of a few millimeters from the front 7 of the handle 1. This makes a small step 13 formed, behind which the spacing section 3 extends.
  • the insertion section 5 has a push-through opening 12.
  • a countersunk screw screwed into the front side 7 8 penetrates the push-through opening with its shaft 12 and is with its threaded section 8 '' in a screw hole 11 of hard plastic existing core 10 of the handle 1 screwed.
  • the Countersunk head 8 'of the screw 8 is flush in the Screwed surface of the end face 7.
  • the assembly of the Grip by a pressing movement towards the surface normal of sheet 3 can be done. Furthermore, as considered advantageous that on a roughly parallel to Rib 4 extending tang can be completely dispensed with can.
  • the manufacture of the handle by injection molding has proven to be beneficial. By design a tool in which the core, which in the Insertion opening 6 is the same shape as the insertion section 5, which generates when the injection molded plastic part occurring shrinkage an adhesive force with the pressure in the insertion opening 6 pressed-in insertion section 5.
  • the assembly can be done with a pneumatic pressure cylinder.
  • the sheet 15 is preferably made of steel.
  • the bracket consists preferably of aluminum.
  • the resistance of the trowel according to the invention is not weakened by the fact that the bracket is manufactured as an aluminum casting.
  • FIG. 5 to 7 differs from that previously described Exemplary embodiment in that the spacing section 3 below the end face 7 a material thickening 20 has, so that the spacing section 3 merges into the end face 7.
  • a joint 21 provided that the width is about 1 mm or less owns. This is a tight pressing on the Handle on the insertion section 5 possible. Under this radial pressure load on the handle 1 can Locking pin 8 can be pushed in or screwed in.
  • the joint 21 occurs when, according to decreasing radial pressure of the insertion section 5 slightly springs out of the radial opening 6.
  • the handle 1 consists of a hard plastic core 10, which in turn consists of two half-open core parts 16, 17 composed.
  • the core parts 16, 17 are inserted one into the other, that they have a closed cavity 22 form.
  • the edge sections 16 ', 17' form catches 23, so that the two core parts 16, 17 are pre-assembled can become and not fall apart.
  • the two core parts 16, 17 can also be glued together become.
  • the core parts 16 on the outer wall of the casing have 17 webs 19.
  • the height of the webs 19 corresponds to the thickness the soft plastic jacket wall 9.
  • the webs 19 serve as centering protrusions when the composite hard plastic core is inserted into an injection mold to to be encapsulated with soft plastic.
  • This soft plastic encapsulation also keeps the two half-open Core parts 16, 17 in connection with each other.
  • the joint 18 between the core parts 16, 17 is made of soft plastic covered. The one after the injection molding Shrinkage of the soft plastic keeps them both Core parts 16, 17 firmly together.
