It is preferable to have an engaging convex portion including a pair of left and right outer surface portions that respectively contact the surface portion, and a bottom surface portion having an arcuate cross-sectional shape that is complementary to the bottom surface portion.

  According to these configurations, while it is a configuration that can be tilted in the front-rear direction, when a load is applied to the left and right from the cane body, the cane body does not tilt (swing) with respect to the stone thrusting body, and the load is It is applied to the left and right contact surfaces through the shaft member and the stone thrusting body. As a result, the weight can be supported at two or more points by the plurality of contact surfaces, and a sense of stability can be given to the user. Thus, the user can swing the head or obtain a high sense of stability by adjusting the load or changing the direction of the cane body. Therefore, a high sense of stability can be given as a sensation while allowing the cane body to tilt freely. Here, the “ground” is a ground in a broad sense, and is a concept including a road surface and a floor surface from the ground in a narrow sense.

  Further, a tilt restricting portion for restricting the maximum tilt angle of the shaft member to a constant angle is further provided, and the tilt restricting portion is a flange projecting from the peripheral edge portion of the engaging concave portion and the upper end portion of the engaging convex portion.

That is, the four contact surface members 61 are spaced apart from each other at four positions, front, rear, left and right.

  Here, with reference to FIG. 3 and FIG. 4, the detail of the connection structure of the stone thrusting body 31 and the shaft member 32 is demonstrated. Specifically, the engaging convex part 41 of the shaft member 32, the engaging concave part 64 of the stone thrusting body 31, and the connecting member 33 will be described in this order. As shown in FIG. 3, the engaging convex portion 41 of the shaft member 32 has a shape in which the left and right sides excluding the upper end portion are cut away from the downward hemisphere. That is, the engagement convex portion 41 includes a substantially disc-shaped disc portion 81 formed on the upper end portion, and a substantially semi-cylindrical half-cylindrical portion 82 projecting downward from the disc portion 81. Yes. The semi-cylindrical portion 82 has a pair of left and right outer surface portions 83 and a lower surface portion 84 having an arcuate cross section centered on the horizontal axis in the left-right direction. Strictly speaking, as shown in FIG. 3B, the lower surface portion 84 is also formed in a circular arc shape with a horizontal axis in the front-rear direction as the center as viewed from the front-rear direction.

  On the other hand, the engagement concave portion 64 of the stone thrusting body 31 has a complementary shape to the semi-cylindrical portion 82 of the engagement convex portion 41. That is, the engaging recess 64 includes a pair of left and right inner side surfaces 91 that respectively contact the pair of left and right outer surface portions 83, and a bottom surface portion 92 having a circular arc shape that is complementary to the lower surface portion 84. As a result of engaging the engagement protrusion 41 and the engagement recess 64 with each other, tilting of the shaft member 32 in the left-right direction with respect to the stone thrusting body 31 is restricted, and the shaft member with respect to the stone thrusting body 31 is restricted. 32 engages in a tiltable manner in the front-rear direction. Further, the bottom surface portion 92 of the engagement recess 64 is formed with a relief opening 93 of the connection pin 101 for connecting the stone thrusting body 31 and the shaft member 32 while allowing the connection member 33 to tilt. The escape opening 93 is formed by an oval long hole whose longitudinal direction is the front-rear direction.

  The connecting member 33 includes a connecting pin 101 inserted through the relief opening 93 of the engaging recess 64 and the shaft hole 51 of the shaft member 32, and an engaging recess 64 between the head 111 of the connecting pin 101 and the engaging recess 64. The curved plate 102, the two hex nuts 103 screwed to the tip of the connecting pin 101 (above the shaft member 32), and the compression coil interposed between the shaft member 32 and the hex nut 103. And a spring (spring member) 104 (see FIG. 2).

  The curved plate 102 is made of a metal plate such as stainless steel and has a circular arc shape that follows the bottom surface portion 92 of the engaging recess 64. In addition, an insertion hole 105 through which the connecting pin 101 is inserted is formed at the center of the curved plate 102. The curved plate 102 is sandwiched between the head portion 111 of the connecting pin 101 inserted through the insertion hole 105 and the engaging recess 64.

  The connecting pin 101 is connected to the head 111 whose seating surface abuts on the lower surface of the curved plate 102, the insertion hole 105 of the curved plate 102, the relief opening 93 of the engaging recess 64, and the shaft of the shaft member 32. The body portion 112 is inserted into the hole 51. The body portion 112 of the connecting pin 101 is formed to have substantially the same diameter as the insertion hole 105 of the curved plate 102, and is inserted into the insertion hole 105 of the shaft member 32, and the tip portion is exposed from the upper end portion of the shaft hole 51. doing. Further, a male screw 113 for screwing the two hexagon nuts 103 is formed at the distal end portion of the body portion 112. The connecting pin 101 detachably connects the curved plate 102 to the shaft member 32 so as to sandwich the engaging recess 64 with the engaging protrusion 41. Therefore, the connecting pin 101 is prevented from coming off upward by the curved plate 102.

  The compression coil spring 104 is accommodated in the large diameter portion 52 of the shaft hole 51 in the shaft member 32 and supported by the inner peripheral step portion 53. When assembling the cane butt 3, two hexagon nuts 103 are screwed together from the tip of the connecting pin 101 against the compression coil spring 104. As a result, the compression coil spring 103 receives the shaft member 32 (inner peripheral step portion 53) and urges the connection pin 101 in the direction (upward direction) via the two hexagon nuts 103.

  With such a configuration, the connecting pin 101 has a configuration in which the bending plate 102 is detachably connected to the shaft member 32 via the two hexagon nuts 103 and the compression coil spring 103. On the other hand, since the tilting of the connecting pin 101 accompanying the tilting of the shaft member 32 is allowed by the relief opening 93, the connecting member 33 connects the stone thrusting body 31 and the shaft member 32 while allowing the shaft member 32 to tilt. To do.

  Further, as described above, when the central axis B of the stone thrusting body 31 and the axis of the shaft member 32 coincide with each other, the flange portion 42 of the shaft member 32 and the upper peripheral portion (peripheral portion) 64a of the engaging recess 64 are provided. And face each other in parallel with a gap. With this configuration, when the shaft member 32 is tilted by a certain angle (10 °) in the front-rear direction, the flange portion 42 contacts the upper peripheral edge portion 64a. Therefore, the maximum tilt angle of the shaft member 32 and the cane body 2 to which the shaft member 32 is mounted is restricted to a constant angle in the front-rear direction. That is, the tilt restricting portion is configured by the flange portion 42 and the upper peripheral edge portion 64a.

  According to the above configuration, the cane body 2 can be tilted in the front-rear direction with respect to the stone thrusting body 31 by the structure in which the shaft member 32 is connected to the stone thrusting body 31 so as to be tiltable in the front-rear direction (see FIG. 1 and FIG. 6). Therefore, regardless of the horizontal plane or the slope, the ground contact surface of the stone thrusting main body 31 can be reliably brought into contact with the ground. Further, while the structure is tiltable in the front-rear direction, when a load is applied to the left and right from the cane body 2, the cane body 2 is not tilted (swinged) with respect to the stone thrust body 31, and the load is The main body 31 and the shaft member 32 are applied to the two left and right contact surface members 61. As a result, the two contact surface members 61 can support the body weight at two points, and can give the user a sense of stability. In this way, the user can swing the head or obtain a high sense of stability by adjusting the load or changing the direction of the cane body 2. Therefore, a high sense of stability can be given as a sensation while making the cane body 2 tiltable.

  Further, the cane body 2 attached to the shaft member 32 is necessary for walking by restricting the maximum tilt angle of the shaft member 32 to a certain angle by the flange portion 42 and the upper peripheral edge portion 64a of the engagement recess 64. Since there is no more tilting, it is possible to eliminate the danger caused by the cane body 2 being tilted excessively.

  Further, the shaft member 32 is not pulled upward with respect to the stone thrust main body 31 by connecting the stone thrust main body 31 and the shaft member 32 by the connecting member 33. Further, since the connecting pin 101 removably connects the curved plate 102 to the shaft member 32, the stone thrust main body 31 and the shaft member 32 can be easily disassembled by releasing the connection. Therefore, sand particles and the like that have entered the connecting portion can be easily removed.

  Further, since the shaft member 32 is received and the compression coil spring 104 that biases the connection pin 101 in the pulling direction is provided, the connection pin 101 is attracted by the compression coil spring 104 by receiving the shaft member 32. The stone thrust main body 31 and the shaft member 32 are attracted moderately through the pins 101. Therefore, it is possible to maintain the joining condition between the engagement concave portion 64 of the stone thrusting body 31 and the engagement convex portion 41 of the shaft member 32 in an appropriate state, and to appropriately connect the stone thrusting body 31 and the shaft member 32. It can be swung relatively.

  In the present embodiment, the tilt restricting portion is configured by the flange portion 42 and the upper peripheral edge portion 64a. However, the tilt restricting portion includes the curved plate 102 and the lower peripheral edge portion 64b of the engaging recess 64 (FIG. 4). (See (a)). That is, when the shaft member 32 is tilted by a certain angle in the front-rear direction, the curved plate 102 may be in contact with the lower peripheral edge portion 64b to restrict the tilt of the shaft member 32. As a result, the structure which controls the inclination of the shaft member 32 by both structure of the flange part 42 and the upper side peripheral part 64a, and the curved plate 102 and the lower side peripheral part 64b may be sufficient.

  In the present embodiment, the maximum tilt angle of the shaft member 32 is 10 °, but the present invention is not limited to this as long as it is 8 ° or more and 12 ° or less.
