  Hereinafter, embodiments of a peg according to the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing the configuration of a peg 10 according to an embodiment of the present invention. FIG. 2 is a front view showing the configuration of the peg 10, and FIG. 3 is a rear view showing the configuration of the peg 10. As shown in FIG. As shown in FIG. 2, the peg 10 is for fixing the fixing target 12 at the ground surface G. The fixed object 12 shown in FIG. 2 is a soccer goal having a pipe portion 12a, and the peg 10 is configured so that the upper portion of the pipe portion 12a can be pressed from above. The fixed object 12 is not limited to a soccer goal, and may be a tent tension rope, a pet pull rope, or the like. When the fixed object 12 is a tent tension rope or a pet pull rope, it is not necessary to hold them from above, and an annular portion provided on them may be hooked on the peg 10.

  As shown in FIG. 1, the peg 10 includes a shaft portion 14, excavation blades 16, an annular portion 18, a coupling portion 20, and an input portion 22. In the present embodiment, these are formed of a metal such as iron or aluminum, but they may be formed of a synthetic resin.

  As shown in FIG. 2, the shaft portion 14 is a rod-like member embedded in the ground leaving the upper end portion 14 a above the ground surface G. The cross-sectional shape of the shaft portion 14 is circular, and the lower end portion 14b of the shaft portion 14 is formed to be sharp so that the diameter becomes smaller as it goes downward.

  As shown in FIG. 2, the digging blades 16 are provided spirally on the outer peripheral portion of the shaft portion 14. The excavation blade 16 is divided into a first portion 16a, a second portion 16b, and a third portion 16c, and the diameters thereof are D1, D2, and D3 (increase stepwise from below to above). It is assumed that D1 <D2 <D3). The number of turns of each of the first portion 16a, the second portion 16b and the third portion 16c is two or more. As shown in FIGS. 2 and 3, the diameter of the digging blade 16 is rapidly increased at the boundary between the first portion 16 a and the second portion 16 b and at the boundary between the second portion 16 b and the third portion 16 c. The stepped portions 24a and 24b are formed on the lower side. In the present embodiment, the excavation blade 16 is formed integrally with the shaft portion 14 by cutting, but the individually formed excavation blade 16 may be connected to the shaft portion 14 by welding or the like.

  FIG. 4 is an exploded perspective view showing the configuration of the main part of the peg 10. As shown in FIG. 4, the shaft portion 14 includes a main body portion 26 provided with a digging blade 16 (FIG. 1), a rotary shaft portion 28 extending upward from the upper end of the main body portion 26, and a rotary shaft portion And a projecting portion 30 which is formed to extend upward from the upper end of 28. That is, the rotating shaft portion 28 and the projecting portion 30 are provided at the upper end portion 14 a of the shaft portion 14.

  As shown in FIG. 4, the rotation shaft portion 28 is a cylindrical portion that is a rotation shaft for rotating the annular portion 18. The protruding portion 30 is a portion protruding upward from the annular portion 18, and a male screw 32 is formed on the outer peripheral surface of the protruding portion 30. The diameter W1 of the rotating shaft portion 28 is smaller than the diameter W2 of the upper end portion of the main body portion 26 and larger than the diameter W3 of the protruding portion 30. Thereby, a step-like lower facing portion 34 that is opposed to the annular portion 18 from below is provided at the lower end portion of the rotating shaft portion 28, and the input portion 22 is provided at the lower end portion of the protruding portion 30. A stepped stopper 36 is provided to prevent movement downward.

  As shown in FIG. 4, the annular portion 18 has a through hole 40 through which the upper end portion 14 a of the shaft portion 14 is inserted. An inner diameter (that is, a diameter of the through hole 40) W <b> 4 of the annular portion 18 is larger than the diameter W <b> 1 of the rotating shaft portion 28 and smaller than the diameter W <b> 2 of the main body portion 26. The vertical length H1 of the annular portion 18 is shorter than the vertical length H2 of the rotary shaft portion 28. That is, the annular portion 18 is configured to be rotatable in the circumferential direction around the rotation shaft portion 28.

  The dimensional difference (W4-W1) between the inner diameter W4 of the annular portion 18 and the diameter W1 of the rotary shaft portion 28 is set to about 1 to 6 mm. Thus, the position of the annular portion 18 in the direction orthogonal to the shaft portion 14 is adjusted between the outer peripheral surface of the rotating shaft portion 28 (that is, the outer peripheral surface of the upper end portion 14a) and the inner peripheral surface of the through hole 40. A clearance S (FIG. 5) is secured. Moreover, the dimensional difference (W5-D3) between the outer diameter W5 of the annular portion 18 and the diameter D3 of the third portion 16c (FIG. 2) of the digging blade 16 is set to about 15 to 30 mm. Thereby, when the shaft portion 14 is buried in the ground, the lower surface of the outer peripheral portion 18a in the annular portion 18 directly faces the ground surface G as shown in FIG.

  As shown in FIG. 4, the coupling portion 20 is a portion coupled to the fixation target 12 (FIG. 2). The coupling portion 20 of the present embodiment is formed in a hook shape having a curved portion 42 which is convex upward so that the upper portion of the pipe portion 12 a of the fixed object 12 can be pressed from above. The base end 20 a of the joint 20 is connected to the outer peripheral portion 18 a of the annular portion 18 by welding or the like. An end surface (hereinafter, referred to as a “tip surface”) 20 c of the distal end portion 20 b of the coupling portion 20 is disposed above the lower surface of the annular portion 18. Note that the term “coupled” used in the description of the present invention has a broad meaning, and pressing a part of the fixed object 12 from above is only one aspect of “coupled”. For example, a case where the object is simply hooked on a part of the fixed object 12 or a case where the object is connected to the fixed object 12 with a string, a wire, or the like is also included in the “coupling”.

  As shown in FIG. 4, the input part 22 is a part into which the rotational force for rotating the axial part 14 in the circumferential direction is input. The input unit 22 of the present embodiment is a general nut with a washer, and includes a hexagonal nut main body 44 in a plan view and a circular washer portion 46 in a plan view. A through hole 48 is formed in the nut main body 44, and a female screw 50 into which the male screw 32 of the protrusion 30 is screwed is formed on the inner peripheral surface of the through hole 48. The washer portion 46 has an upper facing portion 52 facing the annular portion 18 from above and a facing portion 54 facing the stopper portion 36 from above. The abutment of the opposing portion 54 with the stopper portion 36 prevents the downward movement of the input portion 22 with respect to the shaft portion 14. In the present embodiment, the input part 22, the upper facing part 52, and the facing part 54 are integrally formed, but they may be formed separately. For example, a nut serving as an “input section” and a washer serving as an “upper facing section” and a “facing section” may be formed separately and used as a set.

  The rotation direction of the input unit 22 for moving the input unit 22 downward with respect to the projecting unit 30 coincides with the rotation direction of the excavation blade 16 for embedding the shaft unit 14 in the ground. Therefore, the shaft portion 14 can be embedded in the ground by rotating the input portion 22 in the downward direction.

  FIG. 5 is a perspective view showing an assembly process of the peg 10. As shown in FIG. 5, when assembling the peg 10, first, the annular portion 18 is fitted to the upper end portion 14 a of the shaft portion 14, and this is disposed around the rotating shaft portion 28. Subsequently, the internal thread 50 formed in the input section 22 is screwed into the external thread 32 formed in the projecting section 30, and the input section 22 is rotated by a tool 56 such as a box wrench. 22 (female screw 50) is screwed into the shaft 14 (male screw 32). Then, the input unit 22 is moved downward with respect to the protrusion 30, and the opposing portion 54 of the input unit 22 is abutted against the stopper 36. When the input unit 22 is further rotated from this state, the rotational force is transmitted to the shaft unit 14, and the shaft unit 14 and the excavation blade 16 (FIG. 1) are rotated. When the facing portion 54 of the input portion 22 is in contact with the stopper portion 36, the upper facing portion 52 and the lower facing portion 34 (FIG. 4) are disposed on both sides in the vertical direction of the annular portion 18. In this case, the male screw 32 and the female screw 50 are fixed to each other by a nut lock (adhesive) (not shown).

  As shown in FIG. 2, when fixing the fixation target 12 using the peg 10, first, the location to be fixed of the fixation target 12 is confirmed, and the embedded position P of the peg 10 in the vicinity of that location decide. Subsequently, the lower end portion 14b of the shaft portion 14 is disposed at the embedding position P, and the shaft portion 14 or the input portion 22 is tapped from above with a hammer or the like (not shown) to embed the lower end portion 14b of the shaft portion 14 in the ground. . Thereafter, the tool 56 (FIG. 5) is attached to the input unit 22 and the input unit 22 is rotated by rotating the tool 56. Then, the shaft portion 14 and the digging blade 16 are embedded in the ground while being rotated. At this time, if the coupling portion 20 is disposed offset from the pipe portion 12a, the pipe portion 12a can not be pressed by the coupling portion 20, so the annular portion 18 is rotated or the direction orthogonal to the axial direction is made. Adjust the position of the joint 20 by moving it to. When the bending portion 42 of the coupling portion 20 contacts the pipe portion 12a, the rotation operation of the tool 56 (FIG. 5) is stopped and the tool 56 is removed from the input portion 22. When removing the peg 10, the tool 56 rotates the input unit 22 in the reverse direction.

  According to the present embodiment, the following effects can be achieved by the above configuration. That is, as shown in FIG. 2, since the input part 22 is provided above the annular part 18, when the shaft part 14 is embedded in the ground, it is easy to confirm the position of the input part 22. Moreover, since the input part 22 can be spaced apart upwards from the ground surface G, even when undulations, weeds and the like exist on the ground surface G, these do not easily hinder the operation of rotating the input part 22.

  As shown in FIG. 2, when the shaft portion 14 is embedded in the ground, the lower surface of the outer peripheral portion 18 a of the annular portion 18 directly opposes the ground surface G. Therefore, between the lower surface of the outer peripheral portion 18 a and the ground surface G By sandwiching a spacer (not shown) on the frame, the rotation of the annular portion 18 can be prevented, and the position of the coupling portion 20 can be fixed. In addition, when the diameter of the pipe portion 12a is small (not shown), the lower surface of the outer peripheral portion 18a of the annular portion 18 can be brought into contact with the ground surface G. It can be fixed.

  As shown in FIG. 5, a gap S is provided between the outer peripheral surface of the upper end portion 14 a of the shaft portion 14 and the inner peripheral surface of the through hole 40. On the other hand, the positions of the annular portion 18 and the coupling portion 20 in the orthogonal direction can be adjusted.

  As shown in FIG. 4, the shaft portion 14 is provided with an upper facing portion 52 that faces the annular portion 18 from above and a lower facing portion 34 that faces the annular portion 18 from below. Therefore, the annular portion 18 can be positioned in the axial direction of the shaft portion 14. Moreover, since the input part 22 and the upper facing part 52 are integrally formed, the number of parts can be reduced and manufacturing can be performed at low cost, and the assembly workability can be improved.

  As shown in FIG. 5, since the shaft portion 14 and the input portion 22 are separately formed, these configurations can be simplified and manufactured inexpensively. Further, the rotation direction of the input part 22 for screwing the input part 22 (female screw 50) into the shaft part 14 (male screw 32) and the rotation of the excavation blade 16 (FIG. 1) for embedding the shaft part 14 in the ground. Since the directions coincide with each other, there is no need to specially provide an input portion for rotating the digging blade 16, and manufacturing can be performed inexpensively.

  In addition, in implementation of this invention, it is not limited to the said embodiment, A various change is possible unless it deviates from the objective of this invention. For example, in the above-described embodiment, when the fixed object 12 is fixed, the annular portion 18 is arranged away from the ground surface G. However, as in the other embodiment shown in FIG. You may make it the annular part 18 contact the ground surface G by extending the connection part with the annular part 18 of the base end part 57a upward linearly.

  Further, in the above embodiment, the end face 20c (FIG. 2) of the coupling portion 20 is disposed above the lower surface of the annular portion 18, but as in the other embodiment shown in FIG. The distal end surface 58 c may be disposed below the lower surface of the annular portion 18. In this embodiment, since the tip 58b of the connecting portion 58 can be inserted into the ground, the position of the connecting portion 58 can be fixed and the opening 58d of the connecting portion 58 can be closed with the ground surface G. 8A and 8B, the annular portion 60 may be provided with an insertion portion 62 that is inserted into the ground, separately from the coupling portion 64. . Furthermore, the coupling portion 64 may be formed in a ring shape. When the coupling portion is formed in an annular shape, both end portions 66a and 66b of the U-shaped coupling portion 66 may be connected to the annular portion 68 as in another embodiment shown in FIG. That is, the U-shaped coupling portion 66 and the annular portion 68 may form an annular coupling portion.

  In the case where the fixed object 12 is a tent rope or pet rope, the opening 58 d is closed by the ground surface G to prevent them from being separated from the coupling portion 58 (see FIG. 7), a coupling portion 64 formed in an annular shape (FIGS. 8A and 8B), and a coupling portion 66 in which the opening 66d is closed by the annular portion 68 (FIG. 9) are preferably used.

  Furthermore, in the above-mentioned embodiment, although the input part 22 is comprised with the nut which has the internal thread 50, even if the input part 70 is comprised with the volt | bolt which has the external thread 72 like other embodiment shown in FIG. Good. In this case, the bolt shaft portion 70 a is inserted into the through hole 40 of the annular portion 18 as a “rotating shaft portion”, and the male screw 72 is screwed into the female screw 76 formed at the upper end portion of the shaft portion 74. Furthermore, in the above-described embodiment, the excavation blade 16 is provided on the shaft portion 14, but the shaft portion 14 can be inserted into the soil even if the excavation blade 16 is omitted.
