Description of the Related Art Conventionally, there is provided a footboard main body having a cylindrical portion vertically penetrating at a crossing point of a frame material in which a large number of plant outlets are formed by crossing the frame, and a connecting rod is provided on a side edge thereof. A connecting male part is provided via the above, and a connecting female part is formed on the other side,
A configuration is known in which it can be engaged with another step body. For connecting the connecting male part and the connecting female part in the vertical direction, for example, the connecting male part comprises an upward hook-shaped head, and the cylindrical connecting female part projects from the bottom to the top to form a connecting female part. There is one that is locked to a retaining piece formed on the inner peripheral surface of the. In this case, since the uppermost surfaces of the coupled male portion and the coupled female portion engaged with each other serve as a tread surface and a load is applied, the engaging force may be weakened. In addition, if there is a margin in lateral engagement between the connecting female portion and the connecting male portion, there is a drawback that the engaging portion is affected during expansion and contraction.
Further, for connecting the connecting projection and the connection receiving part to the left and right, for example, the connecting projection is a plate piece having a hook-like shape with a laterally extending end, and the plate piece is horizontally inserted into the hollow of the connection receiving part. There are things that lock. Also in this case, since the connecting projection is made of a thin plate, if a large load is applied via the uppermost surface of the connecting receiving portion, the above-mentioned protruding piece may be damaged, and the engaging portion may be affected during expansion or contraction. There are drawbacks such as receiving.

ない。By horizontally projecting the connecting protrusion into the hollow portion of the connecting receiving portion, the upper surface and the bottom surface of the connecting protrusion contact the inner wall upper surface and the inner wall lower surface of the hollow portion in the vertical direction without a gap.
As a result, the connecting protrusions are restrained in the vertical direction by the connecting receiving portions, so that there is no risk that the connected plant protection treads will be displaced vertically or that there will be a step. Further, even if a load is applied to the uppermost surface of the coupling receiving portion, the load is received by parallel surfaces, so that the load is evenly distributed, and thus stability against pedaling pressure is enhanced.
Further, since the hollow portion of the coupling receiving portion has a gap in the width direction or the front direction with respect to the fitted coupling projection, the engaging portion is affected even if the material expands or contracts. Never.

い。As shown in FIGS. 2 and 3, the connecting projection 6 is a substantially prismatic projecting piece having a top surface 6a and a bottom surface 6b as horizontal planes. On the other hand, the connection receiving portion 7 has a box-shaped horizontal cross-section, and the inner wall upper surface 8a and the inner wall lower surface 8b of the horizontally extending hollow portion 8 are horizontal surfaces. In addition, the hollow portion 8 has an opening for insertion at the front end, and the base end may be closed or open.

にくくなる。The height of the hollow portion 8 is substantially the same as the height of the connecting projection 6, and the upper surface 6a of the connecting projection 6 at the time of fitting.
And the bottom surface 6b are the inner wall upper surface 8a and the inner wall lower surface 8b of the hollow portion 8.
It comes into close contact with and without any clearance, and is fitted in by being restrained in the vertical direction.
In this way, since the abutting portions of the connection receiving portion 7 and the connection protrusion 6 are in surface contact and the abutting area is wide, even if the uppermost surface 7a of the connection receiving portion 7 becomes the tread surface and a load is applied. Since it can be received on a wide surface, the engaging portion is stable and less likely to be damaged.

係合部分の影響を受けることがない。Further, since the hollow portion 8 is formed so as to have a gap in the front direction (the inrush direction) when the connecting protrusion 6 is fitted, the material is not expanded or contracted due to the temperature change. If it occurs, it will not be affected. Similarly, the hollow protrusion 8 may be formed so as to have a gap in the width direction when the connecting protrusion 6 is fitted therein, and is not affected by the engaging portion due to expansion or contraction of the material.

論である。Further, the upper surface 7a of the connection receiving portion 7 is set to a horizontal plane, and the upper surface 7a is set to be the same surface as the tread surface of the upper surface 10a set to the horizontal plane of the step body 10, and the connection receiving portion 7 has a horizontal surface. It is preferable that the bottom surface 7b is set on a horizontal plane and is set on the same plane as the ground contact surface of the lower surface 10b set on the horizontal plane of the step body 10 because the load applied to the plant protection step 1 can be evenly distributed. In addition, in this invention, the shape of the step body 10 is not limited to the above embodiment. In addition, the present invention is not limited to the above embodiment,
Of course, various design changes can be made without changing the gist.

とができて、極めて有益である。As described above, according to the present invention, the abutting surfaces of the connecting projections and the connecting receiving portions of the plant protection footboard are horizontal planes to widen the abutting area, and the upper and lower sides are in contact with each other without any gaps. With this configuration, there is no possibility that many connected plant protection treads will move up and down or a step will occur at the connection point.
Moreover, since the abutting area is wide, the engaging portion can be stabilized against the pedaling pressure. Further, a gap is provided in the lateral direction at the time of connection so that the influence of expansion and contraction of the material can be absorbed, which is extremely useful.
