上記従来のモルタル用こては、全べて手作業で部品加工及び組立てが行なわれ ている。このため、加工及び組立てには手間及び時間を要し、コスト高になって いる。また、柄ａの表面は硬質であり、手で持ったときの感触はあまり良好では ない。また、支え杆ｃと柄ａとの結合は往々にして堅固さが欠け、ある時間使用 すると結合部に緩みが生ずることがあった。 All of the above-mentioned conventional mortar irons are manually processed and assembled. Therefore, it takes time and labor for processing and assembling, resulting in high cost. Further, the surface of the handle a is hard, and the feel when held by hand is not so good. Also, the connection between the support rod c and the handle a is often lacking in rigidity, and the connection may be loosened after a certain period of use.
【０００４】 本考案は、上記従来の問題点に鑑み、支え杆と柄との結合構造を改善して、結 合強度を向上すると共に、結合方式を簡単化し、生産効率を有効に高めることが できるようにした、こての柄の結合構造を実現しようとする。In view of the above conventional problems, the present invention improves the connection structure between the support rod and the handle to improve the connection strength, simplify the connection method, and effectively increase the production efficiency. I will try to realize the connection structure of the trowel handle that I made possible.

As shown in FIG. 1, this embodiment comprises a handle 10, a support rod 20, and a trowel plate 30.
【００１１】 そして、上記柄１０はプラスチック製の中空の殻体１１と、該殻体１１内に収 容される嵌合ピース１６が含まれ、該殻体１１の内部には多数の補強リブ１２が 設けられており、その隣接する補強リブ１２の間には各々容室１３が形成されて いる。また該殻体１１の底面には少なくとも１つの孔１４が設けられている。The handle 10 includes a hollow plastic shell 11 and a fitting piece 16 accommodated in the shell 11. Inside the shell 11, a large number of reinforcing ribs 12 are provided. Are provided, and a chamber 13 is formed between the adjacent reinforcing ribs 12. Further, at least one hole 14 is provided on the bottom surface of the shell 11.
【００１２】 嵌合ピース１６は強靱なポリビニールクロライド（ＰＶＣ）または酢酸繊維（ アセテート）等のプラスチックから作られ、その外周には若干の突起ピースが形 成され、その形状は殻体１１の孔１４に対応する容室１３にガタなく収容できる 形状となっている。また該嵌合ピース１６には殻体１１の孔１４に相対する位置 に垂直方向の通し孔１７が設けられている。The mating piece 16 is made of a strong plastic such as polyvinyl chloride (PVC) or acetic acid fiber (acetate), and some projection pieces are formed on the outer periphery thereof, and the shape is a hole of the shell 11. It is shaped so that it can be accommodated in the chamber 13 corresponding to 14 without play. Further, the fitting piece 16 is provided with a vertical through hole 17 at a position facing the hole 14 of the shell 11.
【００１３】 また、前記殻体１１は上、下両半１１Ａ，１１Ｂから構成され、容室１３が嵌 合ピース１６を包み込んだ後、殻体１１の外部は射出方式による軟質なプラスチ ック層１８で包覆される。この軟質プラスチック層１８にも殻体１１の孔１４と 同じ位置に孔１９が設けられる。The shell 11 is composed of upper and lower halves 11A and 11B, and after the chamber 13 encloses the fitting piece 16, the outside of the shell 11 is a soft plastic layer by an injection method. Overwrapped at 18. The soft plastic layer 18 is also provided with holes 19 at the same positions as the holes 14 of the shell 11.
【００１４】 前記支え杆２０は、適当な長さを持つ円柱形の杆体であり、その外径は嵌合ピ ース１６の通し孔１７の内径よりやや大きい。また該支え杆の上部外周には互い に１８０°離れた位置に所定長さの突起リブ２１が設けられている。また該支え 杆２０の下部は下方に向かって太くなる錐形体２０となっている。The supporting rod 20 is a cylindrical rod having an appropriate length, and its outer diameter is slightly larger than the inner diameter of the through hole 17 of the fitting piece 16. Further, protruding ribs 21 of a predetermined length are provided on the outer periphery of the upper portion of the support rod at positions separated by 180 ° from each other. Further, the lower portion of the supporting rod 20 is a cone-shaped body 20 that becomes thicker downward.
【００１５】 前記こて板３０は、薄い鋼板からなり、その適当位置には支え杆２０の底端が 溶接されている。なお、支え杆２０とこて板３０との結合方法は周知のものであ るが、こて板３０の材質の違いにより、その他の組合固定方式にすることもでき る。The iron plate 30 is made of a thin steel plate, and the bottom end of the supporting rod 20 is welded to the appropriate position thereof. The method of connecting the support rod 20 and the iron plate 30 is well known, but other combination fixing methods can be used depending on the material of the iron plate 30.
【００１６】 次に本実施例の組立順序を説明する。 先ず、支え杆２０の下部の錐形体２０の底端をこて板３０に溶接固定し、支え 杆２０とこて板３０を一体に結合する。次いで、予め嵌合ピース１６を包容した 柄１０の底端の孔１４を支え杆２０の頂端に合わせて柄１０とこて板３０を均衡 状態に保ち、柄１０に下向きの圧力を加える。Next, the assembly sequence of this embodiment will be described. First, the bottom end of the pyramidal body 20 below the supporting rod 20 is welded and fixed to the iron plate 30, and the supporting rod 20 and the iron plate 30 are integrally connected. Next, the hole 14 at the bottom end of the handle 10 containing the fitting piece 16 in advance is supported, and the handle 10 and the trowel plate 30 are kept in equilibrium in accordance with the top end of the rod 20, and downward pressure is applied to the handle 10.
【００１７】 この加圧により、支え杆２０の頂端は柄１０の孔１４を経て、図３に示す如く 嵌合ピース１６の通し孔１７に押し込まれる。また支え杆２０の両側の突起リブ ２１も圧力を受けて嵌合ピース１６の通し孔１７の内周縁の両側へ嵌入される。 そして嵌合ピース１６は、その強靱な性質と強構造の特性により、支え杆２０及 び突起リブ２１の外周を緊密に包覆し、柄１０と支え杆２０を堅固に結合させる 。By this pressurization, the top end of the supporting rod 20 is pushed through the hole 14 of the handle 10 and into the through hole 17 of the fitting piece 16 as shown in FIG. Further, the projecting ribs 21 on both sides of the support rod 20 are also fitted to both sides of the inner peripheral edge of the through hole 17 of the fitting piece 16 under pressure. The fitting piece 16 tightly covers the outer circumference of the supporting rod 20 and the protruding rib 21 due to its tough property and strong structural characteristic, and firmly connects the handle 10 and the supporting rod 20.
【００１８】 図４は本考案の他の最適実施例を示す図で、図３と同一部分を示す断面図であ る。 本実施例は基本的には前実施例と同様であり、異なるところは、柄５０の頂面 に支え杆２０の外径より小さい内径の貫通孔５１を設けると共に、支え杆６０の 頂端にねじ孔６１を設け、該支え杆６０を嵌合ピース１６の通し孔１７に嵌入し た後、更にねじ６２を柄５０の貫通孔５１通して支え杆６０のねじ孔６１に螺入 し、締付けるようにしたことである。FIG. 4 is a view showing another optimum embodiment of the present invention and is a sectional view showing the same portion as FIG. This embodiment is basically the same as the previous embodiment, except that a through hole 51 having an inner diameter smaller than the outer diameter of the support rod 20 is provided on the top surface of the handle 50, and a screw is provided at the top end of the support rod 60. A hole 61 is provided, and after the supporting rod 60 is fitted into the through hole 17 of the fitting piece 16, a screw 62 is further passed through the through hole 51 of the handle 50 and screwed into the screw hole 61 of the supporting rod 60 so as to be tightened. That is what I did.
【００１９】 本実施例によれば、柄５０と支え杆６０をより緊密に結合させる外、更にねじ ６２をねじ孔６１に締め付けることにより、その支え杆６０を引き付け、支え杆 ６０が嵌合ピース１６の通し孔１７に嵌入する深さを増すことができる。従って 使用者は必要に応じて柄５０の底縁とこて板３０の間隔Ｈを短縮することができ 、手の掌の小さい使用者は間隔Ｈを適当に調整することができる。According to the present embodiment, the handle 50 and the supporting rod 60 are more tightly coupled to each other, and the screw 62 is further tightened in the screw hole 61 to attract the supporting rod 60, and the supporting rod 60 is fitted to the fitting piece. The depth of fitting into the through hole 17 of 16 can be increased. Therefore, the user can shorten the interval H between the bottom edge of the handle 50 and the iron plate 30 as needed, and the user with a small palm can adjust the interval H appropriately.
【００２０】 上述した２つの実施例は、柄と支え杆の結合には、支え杆の両側の突起リブを 嵌合ピースの通し孔の周縁に嵌め付けたが、実施例の円柱状の支え杆の代りに角 柱状の支え杆を用いれば、角柱状の周囲には既に突起リブに相当する突部がある ので、嵌合ピースと嵌合した場合、堅固に嵌合でき、且つねじれ回りを防ぐ結合 効果が達成される。In the above-described two embodiments, in order to connect the handle and the supporting rod, the protruding ribs on both sides of the supporting rod are fitted to the peripheral edge of the through hole of the fitting piece. If a prismatic support rod is used instead of, the protrusions that already correspond to the protrusion ribs will already exist around the prismatic shape, so when fitted with a fitting piece, it can be firmly fitted and twisting can be prevented. The combined effect is achieved.
【００２１】 また、支え杆を柄に押し付けて嵌入する場合、柄とこて板の軸方向を互いに平 行させておけば、製品の正確性を確保することができ、その組立もより容易とな り、組立の原価を降下するのみでなく、製品の品質を向上することができる。Further, when the support rod is pressed into the handle and fitted therein, if the handle and the trowel plate are axially parallel to each other, the accuracy of the product can be ensured and the assembling thereof is easier. Therefore, not only the cost of assembly can be lowered, but also the quality of products can be improved.
