【発明が解決しようとする課題】
特許文献１のくし目鏝は、接着面に局部的に多量に塗布された接着剤溜まりを、該接着面に均一に掻き均すとき、該くし目鏝の両側から接着剤溜まりの一部がはみ出し、該掻き均し作業が効率的ではなく、また、接着剤の塗布量も均一になりにくいという問題があった。この従来の問題点を本願の図６、図７を参照して説明する。図６に示す如く、床下地材Ａに塗布された接着剤溜まりＢを従来のくし目鏝Ｃで掻き均すとき、くし目鏝Ｃの両側から接着剤溜まりＢがはみ出し、床下地材Ａの塗布量が均一化されにくく掻き均し作業を繰り返して行う必要があるという問題があった。又、接着剤の塗布量が均一でない場合、本願の図７に示す如く床仕上材Ｄに荷重がかかると、床下地材Ａに多量に塗布された該はみ出し接着剤が床仕上材Ｄの実結合部分から床表面に染み出してくる等の問題があった。本発明は、床面下地面、壁面、その他の接着面に局部的に多量に塗布された接着剤やモルタルの接着剤溜まりを、該接着剤を接着剤塗布用こてからはみ出すことなく、均一に掻き均すことができ、しかもその作業を効率よく行うことができる接着剤塗布用こてを提供することを課題とする。

【００１０】
【発明の実施の形態】
以下、本発明の好ましい実施の形態について、図面を参照してより詳細に説明する。図１は本発明の接着剤塗布用こてに係る第一実施例の斜視図であり、図において、３は全体が合成樹脂で成形された接着剤塗布用こてであり、接着剤塗布用こて３の、正面視三角台形状のこて本体３１の下端縁部にくし目部３２が形成され、該くし目部３２の両側部であってこて本体３１の下端縁部から上方に伸びる一対の袖壁３３、３３が形成されている。袖壁３３は、側面視が三角形状をし、こて本体３１の表面に直交して前方に突出している。該袖壁３３は三角形状に限定されものではなく例えば長方形状であってもよい。又、両袖壁３３、３３は互いに外側に広がるようハの字形に広げた状態で突出させてもよい。更に、接着剤塗布用こて３全体を板金加工で形成してもよい。くし目部２はこて本体３１の下端縁部をのこぎり状に切り欠いて形成したものでありこて本体３１の表裏面に連通している。
【００１１】
図２は、本発明の接着剤塗布用こてに係る第二実施例の平面図であり、該第二実施例は、第一実施例の接着剤塗布用こて３の裏面にも袖壁３３、３３を表面の袖壁３３、３３と対称的に形成したものである。該接着剤塗布用こて３も合成樹脂で一体形成してもよく、板金加工で製作してもよく、また木製で製作してもよい。該第二実施例の接着剤塗布用こて３はその表裏面を使用することができ、接着剤塗布用こて３の耐用年数が大きくなり、接着剤溜まり２を掻き均すとき、必要に応じて、接着剤塗布用こて３を往復動させることができるようにしている。

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings. FIG. 1 is a perspective view of a first embodiment of an adhesive application trowel according to the present invention. In FIG. 1, reference numeral 3 denotes an adhesive application trowel entirely formed of a synthetic resin. A comb 32 is formed at the lower edge of the iron body 31 having a triangular trapezoidal shape as viewed from the front, and extends upward from the lower edge of the iron body 31 on both sides of the comb 32. A pair of sleeve walls 33, 33 are formed. The sleeve wall 33 has a triangular shape in side view, and protrudes forward perpendicular to the surface of the iron body 31. The sleeve wall 33 is not limited to a triangular shape, and may be, for example, a rectangular shape. Further, the two sleeve walls 33 may be extended in a C-shape so as to extend outward. Further, the whole of the adhesive application trowel 3 may be formed by sheet metal processing. The comb portion 2 is formed by cutting the lower edge of the iron body 31 into a saw-like shape, and communicates with the front and back surfaces of the iron body 31.
[0011]
FIG. 2 is a plan view of a second embodiment of the adhesive application trowel according to the present invention. The second embodiment has a sleeve wall on the back surface of the adhesive application trowel 3 of the first embodiment. 33, 33 are formed symmetrically with the sleeve walls 33, 33 on the surface. The adhesive application trowel 3 may be integrally formed of synthetic resin, may be manufactured by sheet metal processing, or may be manufactured of wood. The adhesive application trowel 3 of the second embodiment can use the front and back surfaces thereof, the service life of the adhesive application trowel 3 becomes longer, and it becomes necessary when the adhesive pool 2 is leveled. Accordingly, the adhesive application trowel 3 can be reciprocated.
[0012]
FIG. 3 is a perspective view of a third embodiment of the adhesive application trowel according to the present invention, which is a front surface of the trowel main body 31 in the scraping direction, the surface of the comb portion 32 and The surface of the pair of sleeve walls 33 is formed as a continuous concave curved surface. FIG. 4 is a plan view of a fourth embodiment of the adhesive application trowel according to the present invention. A concave curved surface 34 similar to the concave curved surface 34 of the example is formed symmetrically.
[0013]
Next, an example of use of the adhesive application trowel 3 of the present invention will be described using a third embodiment. FIG. 5 is a schematic plan view showing a use state of the third embodiment. In the figure, when the adhesive pool 2 locally applied to the bonding surface 1 is raked by the adhesive coating iron 3 of the third embodiment, the adhesive pool 2 has a concave curved surface 34 of the adhesive coating iron 3. The pressed adhesive pool 2 passes through the comb portion 32 and is uniformly applied on the bonding surface 1 behind the adhesive application iron 3 in a streak shape. At this time, the action of expanding the adhesive pool 2 in the left and right direction due to the forward movement of the comb portion 32 and the action of trying to gather the adhesive pool 2 inward by the concave curved surface 34 are collected. Interacting with each other, the adhesive reservoir 2 on the front surface of the iron main body 31 is in a state where its tip is located on a substantially straight line orthogonal to the traveling direction of the iron main body 31. This state is maintained until the adhesive pool 2 is almost eliminated, and therefore, the adhesive pool 2 can be evenly uniformly leveled at the comb portions 32.
[0014]
【The invention's effect】
As described above, according to the first aspect of the present invention, a comb portion 32 for flattening the adhesive pool 2 locally applied to the bonding surface 1 is formed at the lower edge of the ironing body 31. In the adhesive applying trowel 3, a pair of sleeve walls 33, 33 extending from the lower edge of the iron main body 31 on both sides of the comb portion 32 and protruding in the scraping direction are formed. Since the adhesive applying trowel is characterized in that the adhesive pool 2 locally applied to the adhesive surface 1 is raked, the front surface of the comb portion 32 between the pair of sleeve walls 33, 33. When the adhesive pool 2 corresponding to the size of the adhesive coating iron 3 is applied to the bonding surface 1, the adhesive pool 2 is removed by the adhesive coating iron 3. The adhesive is applied to the adhesive surface 1 substantially uniformly without spilling from the sleeve walls 33, 33 on both sides. But they can.
[0015]
According to the second aspect of the present invention, the pair of sleeve walls 33 are formed so as to protrude at the predetermined locations on the front and back surfaces of the main body 31. The front and back surfaces of the trowel 3 can be used, and the service life of the trowel 3 for applying an adhesive is increased. By reciprocating, the scraping operation can be performed efficiently.

Since the surface is formed as a continuous concave curved surface 34, when the adhesive pool 2 is raked by the adhesive application trowel 3, the adhesive pool 2 accompanying the forward movement of the comb portion 32 is moved in the left-right direction. The action of expanding the adhesive and the action of gathering the adhesive pool 2 by the concave curved surface 34 inwardly interact, and the adhesive pool 2 on the front surface of the adhesive application trowel 3 is formed. The adhesive reservoir 2 can be evenly uniformly leveled by the comb portion 32 until it is almost eliminated.
