Definitions

  • the present invention relates to an apparatus for finishing a floor surface, to be used for finishing a non-dried concrete or mortar floor in a construction site in which a building or various concrete structures is(are) being built.
  • a step of "floor leveling” is carried out for flattening raw concrete poured to a target construction site. Then, the concrete is aged for hours, and is wholly pressurized to be flattened by means of a floor surface leveler called "a trowel”. Finally, those skilled in the art manually finish the concrete floor by means of a finishing trowel (a rectangular trowel).
  • a typical floor surface leveler used for leveling a floor surface includes a powered rotary trowel capable of rotating like a propeller while being in contact with a concreter floor (for instance, see the patent documents 1 and 2).
  • each of these apparatuses is designed to include a rotary trowel powered by a motor to rotate like a propeller, and a finishing trowel in the form of a flat plate for flattening a floor having been leveled by the rotary trowel.
  • the apparatuses suggested in the patent documents 3 to 6 are designed to remove stripe-shaped rotary marks remaining on a concrete floor having been leveled by the propeller-like rotary trowel, by means of the flat-plate shaped finishing trowel sliding on the concrete floor while following the rotary trowel.
  • the fact is that small irregularities and/or stripe-shaped marks both of which a person can visually and easily recognize remain on a concrete floor even after those apparatuses passed on the concrete floor.
  • the apparatuses for finishing a floor are designed to compress a concrete floor by applying a force caused by an elastic material such as a spring to a finishing trowel in the vicinity of opposite left and right edges.
  • an elastic material such as a spring
  • the compression force concentrates in the vicinity of left and right edges of a finishing trowel, and hence, stripe-shaped marks remain on a concrete floor in a route in which the left and right edges passed.
  • the left and right edges of a finishing trowel are bound, the left and right edges are poor in an ability to follow the irregularities of a non-finished concrete floor.
  • the apparatus for finishing a floor surface is designed to include a lever like a brake lever of a bicycle, located at a handle. While an operator is grasping the lever with hands, a metal plate of a trowel makes contact with a concrete floor to thereby finish the concrete floor. Accordingly, the operator has to grasp the lever without pauses while the concrete floor is being finished by the trowel, and hence, high physical burden exerts on the operator. Furthermore, if a grip with which the operator grasps the lever varies, both an angle by which the trowel inclines and a compressive force acting on the concrete floor immediately vary, resulting in it almost impossible to accomplish a regularly finished floor.
  • finishing trowel since the action of a finishing trowel is bound by a wire connected to the lever, the finishing trowel can poorly follow irregularities of a non-finished concrete floor. Thus, similarly to the apparatuses disclosed in the patent documents 3 and 4, it is not possible to finish the concrete floor in accordance with a condition of the concrete floor.
  • the apparatus for finishing a floor surface is designed to have a system in which an operator controls a handle for inclining a main body including a rotary trowel to thereby control a direction in which the apparatus moves.
  • the finishing trowel is inclined following the main body, resulting in that a compressive force with which the finishing trowel compresses a floor surface varies each time the main body is inclined, and hence, irregularities are unavoidably generated at a finished floor.
  • the inventor has long studied an apparatus for finishing a floor surface, and invented an apparatus capable of finishing a concrete floor without manual labor of those skilled in the art.
  • the apparatus was disclosed in the patent document 7.
  • the apparatus for finishing a floor surface, disclosed in the patent document 7 makes it possible to build a flat and visually superior concrete floor in a relatively short period of time with the result that it is possible to reduce work volume of an operator, and finish a concrete floor without those skilled in the art.
  • the apparatus 60 includes a floor surface leveler 165, and a finishing trowel 68 connected to a rear of the floor surface leveler 165 through two elevation arms 65.
  • the finishing trowel 68 includes a pair of rotary trowels 63 powered by a motor (not illustrated) to rotate like a propeller, located at right and left sides of the floor surface leveler 165.
  • a mount section S is situated above the floor surface leveler 165 for an operator to sit thereon.
  • the two elevation arms 65 are rotatably connected to a horizontal support shaft 64 located at a rear of the floor surface leveler 165.
  • the horizontal support shaft 64 is centrally connected to a vertical support shaft 62 standing at a center and at a rear of the floor surface leveler 165.
  • the horizontal support shaft 64 is rotatable around a center of the vertical support shaft 62.
  • a pulley 67 is connected to a center of the finishing trowel 68 to which the elevation arms 65 are connected to through distal ends thereof.
  • a pulley 69 is arranged at an upper end of the vertical support shaft 62.
  • the finishing trowel 68 is able to elevate while rotating around the horizontal support shaft 64, and further, is able to swing around the vertical support shaft 62.
  • a wire 64 wound at a proximal end thereof around a wind-up machine 61 powered by a motor is wound at a distal end thereof around the pulley through the pulley 69, and is fixed to the vertical support shaft 69 with being U-turned by the pulley 67.
  • An operator (not illustrated) sits on a mount section S, grasps two control handles H with two hands, and actuates the handles to the front, the rear, the left or the right to thereby cause the apparatus 60 as well as the floor surface leveler 165 to move forwardly or backwardly, turn to the right or the left, or change a direction in which the apparatus 60 goes.
  • the rotary trowels 63 rotating like a propeller pressurize and thereby level a floor surface to be finished, and thereafter, the floor surface is finished by means of the finishing trowel 68 sliding on the floor, following the floor surface leveler 165.
  • the finishing trowel 68 can be designed to have an increased size in a width-wise direction W (a direction perpendicular to the direction indicated with the arrow P) of the floor surface leveler 165. Consequently, it is possible to broadly finish a target floor surface due to single movement of the apparatus 60 by causing the apparatus 60 including the finishing trowel 68 having a great size in the width-wise direction W, to travel in a direction indicated with the arrow P, resulting in it possible to enhance an efficiency with which a floor is finished in the case that a target floor surface to be finished is broad.
  • the conventional apparatus 60 for finishing a floor surface is superior in being able to broadly finish a target floor surface by single movement thereof.
  • the control handles H to attempt to turn the apparatus 60 while a concrete floor is being finished by the apparatus 60, for instance, when the apparatus 60 is attempted to turn to the left (in a direction indicated with an arrow L), the floor surface leveler 165 is directed towards the direction L prior to the finishing trowel 68.
  • finishing trowel 68 is put into a condition in which the finishing trowel 68 is directed obliquely relative to the floor surface leveler 165 when viewed vertically, that is, the finishing trowel 68x is put into a condition indicated with alternate long and two short dashes line shown in FIG. 10 .
  • the finishing trowel 68x makes abutment at a left edge 68xa thereof with a target floor surface to thereby possibly damage the target floor surface.
  • the finishing trowel 68 makes abutment at a right edge 68xb thereof with a target floor surface, or scrapes a target floor surface to thereby damage the target floor surface.
  • the finishing trowel 68 makes abutment at the edge 68xa or 68xb thereof located inner side of a direction in which the apparatus 60 attempts to swing, with a target floor surface, or scrapes a target floor surface, resulting in that the target floor surface is possibly damage.
  • the finishing trowel 68 was lifted to thereby space from the target floor surface, and then, the apparatus 60 was turned.
  • the present invention provides an apparatus for finishing a floor surface, including a floor surface leveler having a powered rotary trowel rotating like a propeller while making contact with a floor surface to be finished, a finishing trowel having elasticity and being in the form of a flat plate, the finishing trowel being connected to the floor surface leveler through connector means such that the finishing trowel is disposed at a part of the outer periphery of the floor surface leveler, and compressing means for compressing the finishing trowel onto the floor surface, the connector means connecting finishing trowel to the floor surface leveler so that the finishing trowel making contact with the floor surface is vertically movable and horizontally swingable around the floor surface leveler, and further so that the finishing trowel is capable of moving towards and away from the floor surface leveler.
  • the connector means may be designed to include a shaft receiver formed with an elongate slit having a longer radius extending in a direction in which the connector means connects the finishing trowel to the floor surface leveler, and a shaft supported in the elongate slit such that the shaft is able to move in the direction.
