The rivet 2 is inserted by combining the long hole 13 of the mounting member 10, the insertion hole 32 of the slide piece 30, and the insertion hole 22 of the butterfly spring 20, and the three are joined. Instead of the rivet 2, bolts and nuts may be used as a coupling tool.

  Thus, the slide piece 30 and the butterfly spring 20 are fixed to each other by the rivet 2 through the insertion holes 22 and 32, and are coupled so that the relative positional relationship does not fluctuate. Is coupled to the mounting member 10 so that it can slide relative to the mounting member 10 through the elongated hole 13.

  The holding member 40 may be connected to the slide piece 30 before the three members are combined, or the holding member 40 may be connected after the three members are combined. In addition, the slide piece 30 and the butterfly spring 20 may be coupled in a state where the mounting member 10 is fixed to a wall or the like, but three members may be coupled before construction on site.

  2A and 2B are schematic longitudinal sectional views showing two examples of a state in which the slide piece 30 is fixed to the mounting member 10 using the butterfly spring 20.

  In the example of FIG. 2A, the convex portions 15, 15... Formed on the extended piece 14 of the mounting member 10 with respect to the two concave portions 25, 25 formed in the opening 24 of the knob portion 23 of the butterfly spring 20. .. In which the third and fourth convex portions 15, 15 from the mounting portion 11 side are fitted, and the example of FIG. 2B shows two concave portions 25, 25 of the opening 24. On the other hand, the state which the 6th and 7th convex parts 15 and 15 fitted from the attachment part 11 side was shown.

  In other words, the n-th and (n + 1) -th (n is one of 1 to 8 in the figure) projections 15 and 15 of the mounting member 10 are fitted into the opening 24 of the butterfly spring 20.

  According to the illustrated example of the present embodiment, the position and size of the long hole 13 of the mounting member 10, the position and number of the convex portion 15, the position of the insertion hole 32 of the slide piece 30, the position and number of the concave portion 25 of the butterfly spring 20. From these combinational relationships, two sets of convex portions 15 and 15 and concave portions 25 and 25 are configured to be fitted. However, the present invention is not limited to this, and any configuration may be used as long as one set of the convex portions 15 and the concave portions 25 are fitted, but in order to firmly attach the slide piece 30, a plurality of sets of convex portions 15 and 15 and the concave portions 25 and 25 are provided. It is desirable to have a configuration that fits.

  Further, in a state where the two sets of convex portions 15 and 15 and the concave portions 25 and 25 are fitted, n−1, between the n th convex portions, between the n, n + 1 th convex portions, and n + 1, n + 2 th convex portions. Each inter-convex portion 16 is provided between the arm portion 23b on the wall side (right side in FIG. 2) of the knob portion 23 of the butterfly spring 20, the partition portion 23a, and the arm portion 23b on the heel side (left side in FIG. 2).

  Thus, this heel support 1 can make the protrusion degree of the slide piece 30 differ by fitting the recessed part 25 formed in the butterfly spring 20 with the appropriate convex part 15 of the attachment member 10. It is like that.

  Thus, the advance / retreat adjustment for making the slide piece 30 have various protrusions is performed by operating the knob portion 23 of the butterfly spring 20 as shown in FIGS.

  FIG. 3A is a longitudinal sectional view showing a state in which the convex portion 15 and the concave portion 25 are fitted and the slide piece 30 is fixed. In this state, the knob portions 23 and 23 are pinched in the direction of the arrow. When the knob portions 23 and 23 are elastically deformed, the fitting of the convex portion 15 and the concave portion 25 is released, and the state shown in FIG. In this state, the butterfly spring 20 is slid along the elongated hole 13 of the mounting member 10 together with the slide piece 30 while pinching the knob parts 23, 23, and fingers are released at a desired position to bring the knob parts 23, 23 back to the original positions. If it returns to this state, it will be in the state which the recessed part 25 fits into the convex part 15, and cannot slide.

  In this way, the advancement / retraction adjustment of the slide piece 30 can be performed only by the knob operation of the knob portions 23, 23 of the butterfly spring 20. Since the slide spring can be adjusted only by one-touch operation of the butterfly spring 20 with one hand, advance / retreat adjustment at the site can be performed easily and quickly.

  In addition, the butterfly spring 20 and the slide piece 30 are configured to be fixed to each other and integrated so that the slide adjustment can be performed while the relative positional relationship does not change. Slide adjustment is possible without any problems.

  Furthermore, since it is not necessary to release the coupling between the butterfly spring 20 and the slide piece 30 when performing advance / retreat adjustment, it is not necessary to remove the bolt / nut for advance / retreat adjustment even when coupled with bolts / nuts. Very good.

  Further, with the slide piece 30 sandwiched between the butterfly spring 20 and the mounting member 10, the locking portions provided on the opposing surfaces of the knob portion 23 of the butterfly spring 20 and the extending piece 14 of the mounting member 10 are connected to each other. Since it is a fixing structure that is locked by the (concave portion 25 and convex portion 15), the butterfly spring 20 is firmly fixed to the mounting member 10 fixed to the wall or the like, and the slide piece 30 fixed to the butterfly spring 20 is also the same. It is firmly fixed.

  In order to facilitate the sliding movement, it is desirable to provide a slight gap between the main body portion 12 of the mounting member 10, the slide piece 30, and the base plate portion 21 of the butterfly spring 20 for riveting. Even if there is a clearance, the butterfly spring 20 is locked and fixed to the mounting member 10 in a state where the spring of the butterfly spring 20 is not acting. Therefore, the slide piece 30 in a fixed relationship with the butterfly spring 20. There is no risk of moving.

  In this embodiment, the mounting member 10 and the butterfly spring 20 are locked by the convex portion 15 and the concave portion 25, and a plurality of the convex portions 15 are formed at equal intervals along the sliding direction. Can be adjusted step by step. Fine adjustment can be performed by reducing the pitch.

  Further, the butterfly spring 20 is provided with two concave portions 25, 25 corresponding to two of the nine convex portions 15, 15. A stronger fixation can be expected.

  In the example of this embodiment, two concave portions 25, 25 are formed in the knob portion 23 of the butterfly spring 20, and the outer ends of the two convex portions 15, 15 fitted to them are the inner ends of the arm portion 23b. Therefore, the opening 24 may be configured not to have the partition portion 23a.

  Further, each outer end of the two convex portions 15 and 15 does not contact the inner end of the arm portion 23b, and each inner end contacts the both ends of the partition portion 23a, that is, two adjacent convex portions 15 and 15 The structure which pinches | interposes the partition part 23a may be sufficient. Further, the knob portion 23 of the butterfly spring 20 may have a structure having concave portions 25 and 25 corresponding to the two non-adjacent convex portions 15 and 15.
