Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an assembly type gateball stake that is easy to assemble and disassemble.

[Conventional technology]

BACKGROUND ART Conventionally, an assembly type gate ball stake is already known, which is attached by screwing a handle having a bolt protruding from the tip into a hole in a head having a female threaded portion in the center. Further, there are already known assembly type gate ball stakes in which the handle is constructed from two or more tiers of members. These gateball stakes are standard with an overall length of 71cm or 80cm, a head diameter of 45mm, and a head length of 24cm.In the case of an assembled type, hold the head with one hand and touch the tip of the handle with the other hand. The tip of the handle had to be rotated and screwed into the hole in the grip head. However, since the diameter near the tip of the handle is small, it was difficult to firmly tighten the handle even if the handle was held and rotated. For this reason, if you try to tighten by holding the base end of a large-diameter handle and the head, the distance between your hands will become large, and when the handle is made up of multiple handle members, each tapered abutting part will be difficult to tighten. It rotated easily and the handle could not be tightened sufficiently against the head. Furthermore, it was not easy to remove the handle from the head once it was tightly tightened.

[Problem that the invention attempts to solve]

An object of the present invention is to provide an assembly type gateball stake whose handle can be easily attached and detached.

[Means for solving problems]

The assembly type gateball stick of the present invention is capable of being attached to and detached from the head by gripping the large diameter part while the handle is in the retracted state.Examples of the present invention will be described in detail with reference to the drawings.

[Embodiment 1] FIG. 1 shows a front view of the assembly type gateball stake of the present invention, disassembled into a head 4 and a retracted handle 1. FIG. 2 shows the retracted handle 1 of FIG. 1 in a side sectional view along the - line. FIG. 3 is a front view showing the gate ball stake of FIG. 1 in an assembled state.

In the embodiment, the retractable handle 1 consists of a handle member 2 that serves as a grip and a handle member 3 having a smaller diameter than the handle member 2, and the handle member 3 is stored in the handle member 2, and as shown in FIG. The outer surface of the proximal end abuts the inner surface of the end portion of the handle member 2, which has a small diameter, and can be fed out.

As shown in FIGS. 1 and 2, a locking portion 2 consisting of a plurality of axial grooves is formed on the inner wall of the end portion of the handle member 2.
In the vicinity of the tip 5 of the handle member 3 inserted into the handle member 2, a locking portion 3a consisting of a plurality of protrusions corresponds to the locking portion 2a of the handle member 2. It is provided. Therefore, as shown in FIG. 1, when the handle member 3 is stored in the handle member 2, the locking part 3a is locked with the locking part 2a, so the handle
When attaching the handle 1, the handle 1 can be firmly attached by grasping and rotating the large-diameter part of the handle member 2 that is easy to apply force to. After attachment, as shown in FIG. 3, the stored handle member 3 is let out and the gateball stake is ready for use. Conversely, when storing the gateball stick, the handle member 2 is pushed toward the head 4 to release the contact with the handle member 3, and the handle member 3 is stored inside the handle member 2, thereby shortening the handle 1. Then, remove the handle 1 from the head as shown in Figure 1.

FIG. 4 shows an example in which the locking portion 2a of the handle member 2 of the handle 1 is formed into a slit-like notch in the gateball stake of the present invention. FIG. 5 is a sectional view taken along the line in FIG. 4 and shows the locked state of the handle member 2 of the handle member 3, and the shape of the locking portion 3a is the same as that shown in FIGS. 1 to 3. .

[Embodiment 2] FIG. 6 is a cutaway front view of another example of the assembled gate ball stake of the present invention.
FIG. 7 is an enlarged side sectional view taken along the line of FIG. 6 and shows the main parts.

In this example, a cross-shaped locking portion 2a is protruded from the rear end of a handle member 2 constituting the handle 1, and a notch-shaped locking portion 3a is recessed from the rear end of the handle member 3. Therefore, the handle 1 can be attached to and detached from the head 4 in a retracted state in the same manner as described in the previous embodiment.

FIG. 8 shows another example of the present invention, which is a front view with the main part of the handle cut away. Figure 9 is the 8th
FIG.

In this example, a locking part 2a consisting of a hexagonal hole is recessed at the rear end of the handle member 2, and a hexagonal nut-shaped locking part 3a that fits into the locking part 2a is provided at the rear end of the handle member 3. Similarly, the handle can be attached to and removed from the bed 4 while the handle 1 is stored.
In the second embodiment, the locking portions 2a and 3a are both built-in, so that the locking portions are not visible from the outside.

[Effect of idea]

The present invention has the following advantages.

A strong assembly is possible.

Easy to assemble and disassemble.
