  In recent years, it has been desired to further improve the coupling force between the C-shaped member and the engaging member engaged with the C-shaped member. In particular, even when the C-shaped member and the engaging member are deformed by an external load, the coupled state is maintained. What is sustainable is needed. Further, in the above engaging member, when the locking claw is inserted into the C-shaped member, the portion that comes into contact with the lip portion is the end face of the plate-shaped trapezoidal portion. There is a possibility that the locking claw may be damaged, and there is a possibility that the coupling state with the C-shaped member cannot be maintained. In addition, even when the material forming the C-shaped member is harder than the material forming the locking claw, the locking claw may be damaged when the locking claw is inserted into the C-shaped member. There is a possibility that the coupled state between the engaging member and the C-shaped member cannot be maintained.

  The present invention has been made to solve such a problem, and is an engagement member and an engagement member capable of preventing damage to the lip protrusion and improving the coupling force with the C-shaped member. An object is to provide a combination member set.

The lip wall 6 is elastically deformed when the trapezoidal portion 13 is inserted, and can lock a lip projection 14 formed on the trapezoidal portion 13 to be described later.

  As shown in FIGS. 1 and 3, the field edge receiver 3 has a substantially U-shaped cross section, and is erected from a flat plate portion 10 extending in the X-axis direction, and both side edges of the plate portion 10. A pair of facing wall portions 11 and 11 facing each other. As shown in FIGS. 1 and 4, a plurality of neck portions 12 extending in the Z-axis direction are arranged in parallel on the facing wall portion 11 in the X-axis direction. As shown in FIG. 2, the width of the neck 12 in the X-axis direction is substantially the same as the length between the pair of lip pieces 8, 8 on the field edge 2. A substantially trapezoidal trapezoidal portion 13 is formed on the distal end side of the neck portion 12. The trapezoidal portion 13 has a lower bottom portion disposed on the neck portion 12 side, and both sides of the lower bottom portion protrude in the X-axis direction and can be engaged with a pair of lip walls 6 and 6 on the field edge 2. 14 and 14 are configured. The lip protrusion 14 is locked to the end portion 8a of the lip piece 8 of the field edge 2 in the Z-axis direction.

  Here, as shown in FIGS. 1 to 5, the lip protrusion 14 is bent inward (inward) in the Y-axis direction from both side edge portions in the X-axis direction, and is engaged with the pair of lip walls 6, 6. A pair of spring plate portions (bending pieces) 15, 15 that can be joined is provided. Specifically, the spring plate portion 15 is bent at an obtuse angle from the oblique side of the trapezoidal portion 13 and has a spring property. That is, as shown in FIG. 5, the angle θ formed by the trapezoidal portion 13 and the spring plate portion 15 is an obtuse angle in plan view. The spring plate portion 15 is disposed at a position where it can be inserted into the lip groove 9. Further, the spring plate portion 15 has a surface that can come into surface contact with the lip piece 8 of the field edge 2 when the field edge receiver 3 is coupled to the field edge 2.

  Next, a method for connecting the field edge 2 and the field edge receiver 3 configured as described above will be described with reference to FIGS. 6 (a) to 6 (d). First, as shown to Fig.6 (a), it arrange | positions so that the opening part between a pair of lip pieces 8 and 8 of the field edge 2 and the trapezoid part 13 of the field edge receiver 3 may mutually oppose. Next, as shown in FIG. 6 (b), the field edge 2 is pressed against the field edge receiver 3, and the trapezoidal portion 13 is inserted between the pair of lip pieces 8 and 8. At this time, the lip piece 8 and the spring plate portion 15 come into contact with each other, and the pair of spring plate portions 15 are elastically deformed in a closing direction so as to approach each other.

It becomes difficult to come off. As a result, it is possible to improve the bonding force between the field edge receiver 3 and the field edge 2. Further, since the spring plate 15 is formed by bending from both side edges of the lip protrusion 14, the spring plate 15 is inserted into the field edge 2 when the lip protrusion 14 is inserted into the field edge 2. By pressing, the force involved can be dispersed. Thereby, it becomes easy to couple the field edge receiver 3 to the field edge 2. Further, when the material constituting the lip piece 8 is harder than the material constituting the lip projection 14 and the spring plate portion 15, the spring plate portion 15 is deformed when the lip projection 14 is inserted into the field edge 2. Thus, it is possible to couple the field edge receiver 3 to the field edge 2 without absorbing the force involved at that time and damaging the lip protrusion 14 and the spring plate part 15. As a result, the material and plate thickness of the field edge 2 and field edge receiver 3 can be freely selected.

  In addition, since the pair of spring plate portions 15 and 15 are bent at an obtuse angle, the distal ends of the pair of spring plate portions 15 and 15 are wider than the width of the lip protrusion 14, so When coupled to the edge 2, the spring back that reopens after the pair of spring plate portions 15, 15 are closed once, and the tip end side of the spring plate portion 15 expands larger than the interval between the pair of lip pieces 8, 8, and more reliably. The spring plate portion 15 can be engaged with the lip piece 8. As a result, the field edge receiver 3 is less likely to be detached from the field edge 2.
