The trowel for trowel with a tapered concave panel according to the present invention is tapered so that the front end portion 110 and the rear end portion 130 can be easily plastered with a small force during a plastering operation through a rounded panel In addition, the flatness of the work surface is increased to provide a function for enabling an untrained general to apply a predetermined uniform thickness.

2 is a perspective view and a plan view of a trowel for trowel with tapered decorative panel according to the present invention.

2, a trowel for trowel with a tapered finished decorative panel according to the present invention includes a plate-shaped plaster panel 100 contacting a working surface of a wall surface or a bottom surface, And a rod-shaped grip part 300 vertically coupled to the upper end of the connection part 200. The rod-

The concave panel 100 includes a front end portion 110 formed to be convex in the front end direction of the plaster panel 100 and a front end portion 110 protruding from both ends of the front end portion 110, And a rear end portion (130) extending from an end of the stop portion (120) and formed to be convex in a rear end direction of the plaster panel (100) , That is, a tapered shape of a front half beam. Therefore, when the plaster panel is placed in contact with the work surface and sliding for plastering, the contact area of the front end portion 110 is advantageous for the progress of the plaster panel 100 because of a narrow contact area. In the case of the rear end portion 130, It is possible to effectively distribute the pressure applied by the operator. As a result, not only a smooth work surface with uniform thickness can be obtained, but also the speed of the plaster can be increased.

The front end 110 and the rear end 130 of the curtain panel 100 according to the present invention are rounded with a predetermined curvature so that the curtain panel 100 is smoothly formed without being twisted desirable. The concave panel 100, which has been rounded at this time, is superior to the concave panel 100 having a conventional angled corner, and the reason thereof will be described in detail below.

As shown in FIG. 1, conventional trowel trowels typically have angled corners such as rectangular or pointed ends 110 in sharpened form. In the case of a trowel for trowel having such angled corners, it is difficult to smoothly slide on the work surface due to the angled corners during the plastering work, and it may be caught between the mortars, or the mortar may flow over the plaster panel 100, There is a risk of dropping. However, since the edge panel 100 according to the present invention has rounded corners, it is possible to solve the problem that the front edge portion 110 is stuck between the mortar or the mortar overflows over the surface panel 100, It will be possible for ordinary people who do not have a uniform thickness to easily plaster.

At this time, the thickness of the plaster panel 100 may be uniform, the thickness may be increased toward the center, and the thickness distribution of the plaster panel 100 may be limited such that one side is thicker than the other side. Do not. It is also possible to manufacture the personalized dressing panel 100 through a method of increasing the thickness of the panel portion in which the loads are concentrated, focusing on the points where the loads are concentrated on the user.

In addition, in the drawings according to the present invention, the curtain panel 100 is shown in a tapered shape having symmetrical both ends, but an asymmetrical tapered curtain panel 100 in which both ends are not symmetrical can also be used have.

In a further embodiment according to the present invention, the structure of the plaster panel 100 is modified so that the mortar touching the edge of the plaster panel 100 can be easily moved toward the rear end 130 at the front end 110 And a space for collecting remaining mortar at the rear end portion 130 is additionally provided, so that it is possible to add the function of allowing the untreated mortar to be re-planarized. Additional embodiments are described in detail below.

FIG. 3 is a perspective view showing a further embodiment of a trowel for finishing according to the present invention, and FIG. 4 is a plan view showing an enlarged view of a finishing panel 100 according to a further embodiment of the present invention.

3 and 4, the plaster panel 100 includes a front end 110, a middle end 120, and a rear end 130 as described above. In this case, Can be further divided into a first front end 111 having a convexly protruding shape with a positive curvature and a second front end 112 having a concave shape with a negative curvature. The intermediate portion 120 may include a rounded first end portion 121 and a second intermediate portion 122 in a tapered straight line shape. The rear end 130 includes first and second protruding parts 131 and 132 protruding from the outer surface of the concave panel and concave portions 133 embedded in the inner surface of the concave panel 100 It will be divided again. Further embodiments according to the present invention are described in more detail below.

The front end portion 110 includes a first front end portion 111 protruding from the one side of the center of the front end portion 110 in the direction of the front end of the plaster panel 100, And a second front end portion 112, which is curved inwardly and recessed inwardly of the curtain panel 100, respectively. In other words, a protruding first end portion 111 is formed at the center of the distal end portion 110 and a second distal end portion 112 is formed at both ends of the distal end portion 110. For example, can do.

During the plastering operation using the trowel for trowel 1, the untreated trowel proceeds toward the front end portion 111 and the plaster is applied. At this time, the residual mortar remaining after being plastered by the front end portion 111 smoothly flows down toward the second front end portion 112 formed on the plaster panel 100, And to move to the rear end 130 to be re-planarized.

In this case, the rounding curvature radii of the first and second leading end portions 111 and 112 may be changed, but it is preferable that the radius of curvature of the leading end portion 111 is formed larger than that of the second leading end portion 112 something to do. So that the mortar or soil moved from the leading end 111 to the second leading end 112 can be quickly moved to the flattening portion 120 and planarized.

Second, the intermediate portion 120 includes a first intermediate portion 121, which is formed by extending at both ends of the second front end portion 112 and protruding outwardly from the facet 100, And a second intermediate portion 122 formed at both ends of the intermediate portion 121 so as to be tapered so as to extend from each other.

In other words, the first intermediate portion 121 connects the second distal end portion 112 recessed and embedded and the second distal end portion 122 in a tapered linear shape, and the second distal end portion 112 And smoothly connects the second interrupting portion 122. As a result, the mortar moved to the second leading end portion 112 on the side surface of the plaster panel 100 is flattened and spread out to the outside of the plaster panel 100 or to the second stopping portion 122 And can be flattened again.

Since the second interrupting portion 122 is inclined at a predetermined angle, that is, tilted so as to be widened to each other, occupying the widest area of the plaster panel 100, Full-scale plastering will be achieved. Also, since the handle 300 of the trowel for trowel 1 is positioned on the second intermediate portion 122, pressure is concentrated on the second intermediate portion 122 during the plastering work, So that the pressure is effectively dispersed. It is of course also possible to provide a uniform pressure on the work surface through effective pressure dispersion through a large area, whereby the mortar can be plastered with a predetermined uniform thickness.

As described above, the interrupter 120 according to a further embodiment of the present invention is configured such that the mortar, primarily plastered through the leading end 110, meets with the wide-area interstices 120 and has a predetermined uniform thickness It is possible to provide a function to make it flat. Further, the contact area is gradually widened along the progressing direction through the tapered-shaped stop 120 so that the mortar can be more effectively plastered.

A connecting portion 200 for connecting a handle is formed on the upper surface of the second intermediate portion 122 of the facade panel 100 and a handle 300 is connected to the connecting portion 200. In the case of the connecting part 200, a conventional tongue handle may be combined with the handle 300. However, it is also possible to adjust the angle by attaching a rotary hinge to adjust the angle of the handle 300. [ 1, a conventional type of handle used for a conventional trowel may be used. However, the handle 300 may have various shapes such as a handle or a ring-shaped handle for adjusting the length, The knob of which can be connected and used.

Lastly, the rear end portion 130 is extended from the middle portion 120 and is divided into a direction perpendicular to the plastering direction, and includes first and second protruding parts 131 and 132 protruding outward from the plaster panel And an embedded part 133 embedded in the inside of the decorative panel 100.

 More specifically, the rear end portion 130 includes a recessed portion 133 recessed and formed in the front end direction of the plaster panel 100 from the peripheral side of the rear end portion 130, And first and second protruding parts 131 and 132 protruded from left and right sides of the recessed part 133 due to the recessed part 133, Accordingly, the rear end 130 functions not only to complement and finish the finishing performed by the cutter 120 during the operation, but also to reduce the contact area of the finishing panel 100 Thereby smoothly moving the surface of the trowel 1 over the work surface and allowing the trowel 1 to be easily detached from the work surface.

Also, the mortar, which has not been planarized yet, is gathered by the recessed part 133 due to the structure having the curvature of the rear end 130. As a result, it is possible to quickly grasp the remaining mortar, thereby increasing the efficiency of the plaster.

It is preferable that the first and second protruding parts 131 and 132 have the same curvature, but it is also possible to have different curvatures. In the embodiment of the present invention, the curvature of the first and second protruding parts 131 and 132 is similar to that of the first and second protruding parts 131 and 132, The curvatures of the embedded part 133 and the first and second protruding parts 131 and 132 may be changed and applied according to the viscosity of the plaster material used in the operation.

As described above, the rear end 130 according to a further embodiment of the present invention not only provides the flattening finishing function of the mortar past the leading end 110 and the middle portion 120, but also for the re-planarization of the residual mortar By playing the role of gathering the mortar in the recessed part 133, it is possible to increase the effect of the plaster and obtain a more smooth plaster surface.

In addition, in order to enable the fine trowel to be provided only with the trowel for trowel 1 without the need for an additional trowel blade in a portion where fine finishing work is required such as a corner and a narrow gap, And the blade portion 140 may be further provided. In this case, when fine finishing is required, the blade effect can be enhanced by using the blade 140.

4, the first middle portion 121 is vertically protruded at a predetermined height along the extending direction of the first middle portion 121 at one end of the upper surface of the first middle portion 121, The blade portion 140 may be provided. The knife portion 140 is used for a work surface requiring fine finishing work such as a corner of a wall or a narrow gap, and is formed to be perpendicular to the surface of the plaster panel 100. Since the position of the blade 140 is not limited, it may be formed at one of the left corner and the right corner. However, when the worker is left-handed, the right side of the plaster panel 100 is formed on the left side of the plaster panel 100 when the operator is a right-handed person, and the convenience of the user in delicate plastering work using the cutlery 140 It is not preferable that the blade portion 140 is formed at both ends of the facsimile panel 100 because there is a problem in the side surface finishing.

In addition, since the facade panel 100 and the blade 140 are perpendicular to each other, they can be effectively used for finishing the edge of a wall. In the case of the conventional trowel for plastering, since each side of the vertical plane must be laid one by one at the edge of the wall edge, the trowel for plaster 1 according to the present invention can be plastered on the vertical plane at the same time, Of course, is increased.

5 (b) is a cross-sectional view of the thickness of the blade portion according to a further embodiment of the present invention.

5 (b), the blade unit 140 includes a blade unit 140, which starts from a connecting portion with the first intermediate portion 121, and contacts a virtual vertical line extending perpendicularly to the extending direction of the blade unit 140 And has a thickness gradually decreasing from a portion contacting the virtual vertical line to a termination portion of the blade 140. It is possible to inscribe the blade portion 140 into a narrow gap to insulate it or to finely finely use the blade edge 141 when the edge gap is fine-finished.

In addition, in the trowel for trowel 1 according to the present invention, the thickness of the trowel 1 may be reduced as the finishing panel 100 is terminated, It is possible to prevent the work surface from overflowing onto the plaster panel 100 and to smoothly slide the plaster panel 100.

Fig. 5 (a) is a cross-sectional view of the thickness of a patch panel according to a further embodiment of the present invention.

5 (a), the curtain panel 100 includes a curved panel 100, a curved panel 100, a curved panel 100, a curved panel 100, And may have a shape in which the curved portion has a positive curvature and becomes thinner as it extends from a portion abutting against the virtual vertical line to the end portion of the curtain panel 100. [

This prevents the mortar from overflowing onto the work surface of the artificial trowel 1 over the work surface of the artificial trowel 1 during the work of plastering and prevents the artificial overflow of the rounded work surface due to rounded and thinned plaster panel 100, The plaster panel 100 is smoothly slid over the mortar so that the user can perform the plastering operation with less force. As a result, the planting efficiency can be increased.

An operator using the trowel for trowel 1 according to a further embodiment of the present invention generally applies force to the work surface while placing the trowel panel in contact with a plaster work surface such as a wall surface or a floor surface And a plastering operation is performed in a straight line direction or in a circular arc. At this time, the trowel for trowel 1 is connected to the veneer panel 100 and the veneer panel 100 by using a veneer panel 100 in the shape of a fore-and-aft line extending from the front end 110 to the rear end 130. [ So that the smoothness of the curtain panel 100 can be smoothly increased and the curtain efficiency can be increased on the work surface contacting with the mortar.

In addition, since the front end 110 is also formed of the first and second front end portions 111 and 112, the front end portion 110 can be easily inserted into the mortar and the quality of the plaster can be improved. And it is possible to distribute the pressure applied by the user through the large area of the stopper 120, as well as to achieve full-scale plastering. In addition, since the flattening according to the plaster finishes through the rear end 130 or plays a role of gathering the mortar so that it can be re-planarized, the skilled plasterer as well as the untrained general can easily finish the plastering.

In addition, through the knife portion 140 provided so as to be perpendicular to one side end of the upper surface of the first recessed portion 121 of the facade panel 100, fine or narrow gaps or fine wall surface of the surface vertically touched like the corner of the wall The trowel 1 according to the present invention can be completely finished without needing to have a separate blind knife even in the case of the trowel.

Lastly, by controlling the thickness of the facia 100 and the blade 140, it is possible to more smoothly advance the sliding of the facia 100 on the working surface, It is possible to prevent overflow.

As described above, the trowel for trowel with tapered finished panel according to the present invention is described in the above description and drawings, but the description of the present invention is not limited to the above description and drawings, It will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit of the invention.
