Definitions

  • the invention is directed to a smoothing trowel, in particular for masonry, with a sheet for receiving, applying and spreading paste-like masses, in particular mortar, on the top of which a fastening web for a handle is attached.
  • the handle consists of a neck part that sits on the fastening web and runs vertically to the sheet, as well as a handle part that runs approximately parallel over the sheet.
  • a throat is arranged on the underside of the handle facing the sheet, between the neck and handle part and the top of the handle facing away from the sheet has a kink, in the area of which a longitudinal axial surface for spreading the thumb of the hand surrounding the handle part is arranged is.
  • the neck consists of a relatively thin metallic shaft which is formed in one piece with the fastening web on the blade on the one hand and an initial piece of the handle part on the other and primarily has the task of providing a sufficient distance between the handle and the blade so that when using the smoothing trowel the human hand can grip the handle.
  • the handle part continues to run parallel to the blade relative to the vertical shaft, there is a kink in the starting piece, in the area of which an axial surface for a spreading position of the thumb of the hand encompassing the handle part arises through a longitudinally central hollow, but which can only be used in a specific working position. But trowels have to take on different working positions, which result from their work sequence.
  • the invention has for its object to develop an inexpensive trowel of the type mentioned, which allows the work to be carried out easily and conveniently.
  • the trowel according to the invention there is a new, optimal grip with spread thumb in all working positions, which comes into contact with the various axial or longitudinal surfaces of the control section. Only the ball of the hand and the other fingers come into contact in the area of the handle, which is essential for a firm grip on the handle.
  • the rotations and tilts of the blade required for the reversing movement of the trowel can be conveniently brought about, controlled and fixed by the special grip between the thumb and forefinger in the area of the angled control section. In the control section, the grip between the index finger and thumb can be rolled off and tilted slightly.
  • the neck part included in the control section thus, together with the straight piece belonging to it, fulfills a new important function of determining and reversing the position of the blade in the hand.
  • This new manual adjustment the focus of the trowel handling shifts in the direction of the spread thumb on the leading edge of the sheet.
  • the spread thumb determines a sense of direction in the hand grip of the trowel, which does not have to be determined with the eye.
  • the longitudinal edges and the kinks in the angled control section are tactile transitions that provide reliable feedback to the human brain about the spatial position of the tool in the hand.
  • the eye is free to be able to observe the work result achieved with the tool when applying the plaster.
  • the required longitudinal position of the hand on the tool is felt without looking.
  • the two kinks interact with the joints between the palm, thumb and fingers to determine the correct longitudinal position of the hand, while the longitudinal edges between the axial and longitudinal surfaces determine the rotational position of the handle. You can also feel the reversing movements of this control section between the various working positions, the control section rolling between the thumb on the axial and longitudinal surfaces and the index finger on the throat of the underside of the handle.
  • the angled control section is so far offset with its neck part on the front edge of the sheet that the center of the sheet is aligned approximately with the upper kink transition between the handle part and the straight piece. It has proven useful to have the straight piece form an angle of inclination between 40 ° and 45 °, but preferably 43 °, with the plane of the blade and to give the handle part an inclination of 3 ° with respect to the plane of the blade. This is the best way to achieve the various working positions in the foot area, overhead or on the side in front of the body.
  • the handle part expediently has a spindle shape tapering towards its free end, which has a maximum cross-section in the central region of the handle part and forms a more sagging belly on the underside because this is more favorable for a firm grip on the handle part.
  • the smoothing trowel consists of a flat sheet 10 with a rectangular outline made of stainless steel and a handle 20 which is molded from plastic and has two functionally different sections 21, 22.
  • the handle 20 initially comprises a grip part 21 for a manual grip, which can best be seen in FIG. 11, around which the palm and, with the exception of the thumb 12, the fingers lie.
  • the handle part 21, as best shown in FIG. 2, has the shape of a bulbous spindle which tapers towards the free end 23, which is rounded.
  • the profile outline As to the profile of the grip part 21 shown in FIGS. 4 and 5, there is a non-uniform profile outline. In the area of the upper side 23 of the handle part 21 up to approximately the two side surfaces, the profile outline follows a uniform circular line, while on its underside 26 there is a greater curvature, which is particularly pronounced in the middle part of this holding section 21.
  • This grip part 21 is formed in one piece with a specially designed control section 22, which, according to the normal hand grip shown in FIG. 11, comes to lie between the thumb 12 spread by the hand and the side surface of the index finger 13.
  • This control section 22 is due to a Kinks 30 angled. If the control section 22 is viewed along the upper side 24 of the handle, the leg pieces lying on both sides of the kink transition 30, namely a vertical neck part 32 and an inclined straight piece 31, are of approximately the same length. On the upper side there is yet another kink transition 33 between this control section 22 and the aforementioned handle part 21.
  • the vertical neck part 32 is seated on a web 18 fastened along the sheet 10, while the straight piece 31, as is evident from the auxiliary line 14 from FIG. 1, with the sheet plane includes an inclination angle 15 of preferably 43 °.
  • control section 22 On its upper side facing away from the sheet 10, the control section 22 is provided with three longitudinal, respectively flat surfaces 34, 35, 35 'which are symmetrical with respect to a vertical plane 36 through the apex of the handle, which is indicated by dash-dotted lines in FIG. 2 . These longitudinal surfaces are separated from one another and from the rest of the rounded circumferential profile in the control section 22 by broken longitudinal edges 37, which from the flg. 11 visible spread thumb 12 can be felt clearly. In the normal position of the hand, the thumb 12 lies on the axial surface 34 running in the middle. As best shown in FIG. 1, the transition between the control section 22 and the hat section 21 is formed only by a throat 38 on the underside 26 of the handle 20. on which, in the normal position of FIG.
  • the index finger 13 lies laterally, while the inner surface of the index finger 13 spans the curve in the cross-sectional shape of the throat 38.
  • the ball of the thumb 16 thus presses on the upper side 24 of the grip part 21.
  • the aligned position of the sheet 10 can be felt by the thumb 12 through the double-sided longitudinal edges 37 of the longitudinally central axial surface 34.
  • the correct longitudinal position of the hand is also determined because, according to FIG. 11, the hand-side thumb joint 17 is positioned at the upper kink transition 33 between the handle part 21 and the control section 22.
  • the thumb 12 bears essentially on the straight piece 31 of the control section 22; the neck-side transition 30 is just noticeable from the thumb 12.
  • the control section 22 is thus between the thumb 12 and the index finger 13 and the various rotational positions of the blade can be brought about by allowing this control section to roll between these fingers. This results from the other figures representing other working positions of the sheet, which will be discussed later.
  • the attachment web 18 used to attach the sheet 10 has, as shown by the Stlmanslcht in Fig. 3, a width 19 which is approximately equal to the maximum cross-sectional width 39 of the handle part 21 of the handle 20 located above, which on the one hand for high strength and on the other hand ensures a good level guidance of the sheet 10.
  • the web 18 is connected to the sheet 10 in a conventional manner known per se.
  • a short base 40 is also formed in one piece with the fastening web 18 and already contributes to the formation of the neck part 32, as can already be seen from the continuation of the mentioned axial and longitudinal surfaces 34, 35, 35 'in the base 40.
  • a separating joint 41 is created towards the handle 20.
  • a hinge vertically formed on the base 40 engages in the handle 20, which is made of plastic, and is used for fastening it.
  • the trowel In addition to the working position shown in FIG. 11 for smoothing the applied masses, the trowel also has to perform other tasks which are shown in more detail in FIGS. 8 to 10.
  • the trowel is intended to hold mortar, for which purpose it is to be used with the blade 10 turned upwards, as shown in FIGS. 8 and 9, respectively.
  • the trowel rotates axially about its grip part 21 in the opposite direction to one another.
  • a working position is reached where the thumb 12 rests on the right longitudinal surface 35 of the control section 22 and is arranged in the height region of the lower kink transition 30.
  • the sheet 10 is facing the fingertips around the handle part 21.
  • the sheet is then to be brought into the inclined position shown in FIG. 10, which is achieved by moving the fingers in the area of the control section 22. It is a matter of drawing the mortar 44 taken up onto the wall 43 in a defined plaster thickness 45. This inclination is then fixed by the remaining fingers and the ball of the thumb 16 in the region of the grip part 21.
  • the thumb 12 has slipped onto the left longitudinal surface 35 ′ in the control section 22, and in the process has moved close to the fastening web 18 because of a considerable pressure to be exerted, which is exerted by the ball 16 of the hand on the holding section 21 of the handle.
  • the mortar 44 thereby comes to lie in a wedge between the sheet 10 and the wall 43.
  • FIG. 12 A spreading of the applied masses must also be carried out in the foot area of a vertical wall.
  • Fig. 12 The blade 10 is held vertically, the thumb 12 has slipped into the base 40 of the control section 22, touches the fastening web 18, and is supported on the longitudinally central axial surface 34; the index finger 13 lies on the opposite side of the base 40.
  • the control section 22 is consequently clamped in this lowermost piece between the thumb 12 and index finger 13.
  • the remaining fingers have accordingly slid far away from the grip part 21 onto the control section 22.
  • the middle finger 46 spans the throat 38 on the underside of the handle approximately in the middle of the throat.
  • Fig. 12 there is a fine hold position, where the handle 20 is easily grasped and access is practically only in the control section 22. If a firm pressure is desired, only the ball of the hand 16 on the top of the handle need be pressed while the hand position remains the same.
  • FIGS. 13, 14 work is carried out overhead on the ceiling.
  • pressure is exerted, which is why the ball of the thumb 16 is pressed against the handle 20.
  • the thumb is located on the longitudinally central axial surface 34 and the remaining fingers on the side facing the sheet 10 span the arched belly 27 of the grip part 21.
  • the thumb 12 is advanced far in the control section 22, the front thumb joint 47 being located at the front transition 30 supports.
  • the sheet 10 is also turned towards the ceiling in order to carry out a smoothing work there.
  • the sheet 10 is brought into a laterally offset position with respect to the person holding the trowel.
  • the thumb 12 is still in contact with the longitudinally central axial surface 34, but is, together with the hand, in a rotational position with respect to the plane of symmetry 36 of FIG. 2.
  • a special fine position is shown in Fig. 7, which is required when rubbing a mortar applied to the floor.
  • the hand spans the top of the handle.
  • the index finger 13 is now located above the longitudinally central axial surface 34 and extends over the two kink transitions 30, 33, which thereby define a specific hand position.
  • the thumb 12 engages the control section 22 on a side surface near the aforementioned throat 38, while the middle finger 46 rests in a corresponding position on the opposite side of the control section 22.
  • the upper kink transition 33 between the handle part 21 and the control section 22 is in a vertical alignment with the center 48 of the sheet 10.
  • the control section 22 is arranged in front of the sheet center 48, offset from the front sheet edge 11.
