Description

[Detailed Description of the Invention] The present invention relates to a rugby scrum training machine.

Currently, there is no suitable scrum practice machine, so in order to practice scrum, for example, in the case of a set scrum of 8 people, 16
You can't practice unless other practitioners gather together.

The present invention has been proposed in view of the above points, and the purpose is to provide a training machine with a simple configuration that allows even eight people forming a scrum to practice scrum.

An embodiment of the present invention will be explained below with reference to the drawings.
1 is a main frame, which includes a front frame part 2, both side frame parts 3, 3, and a rear frame part 4.
has.

The main frame 1 is mounted in a plane parallel to the ground G by rotatably attaching its front frame part 2 to the side of a support 5 whose lower part is fixed to the ground (or concrete IJ-1-) G. It is designed to be able to swing.

The rotation mechanism has U-shaped brackets 6.6 fixed to two locations on the side surface of the support column 5 that protrudes from the ground surface G, and each bracket 6.6 is sandwiched between the horizontal members 7, 7 of the front frame portion 2. One shaft 8 is inserted through the bracket 6.6 and the cross members 7,7.

2 at the front and rear, sandwiching the rear frame 4 of both side frames 3, 3.
The base of the front and rear links 9, 10 of the book is pivoted 11.1
1, each link 9, 10 is attached rotatably to the ground.
It is designed to be able to swing within a plane perpendicular to fiG.

The tips of each link 9, 10 are rotatably attached to the side frame portion 13 of the rectangular push frame 12 by shafts 14, 14.

In the illustrated example, the lengths of the links 9 and 10 are equal, forming parallel links.

The left and right front links 9 are connected by a single connecting member 15, and a plurality of tension coil springs 16 are stretched between the connecting member 15 and the rear frame portion 4 of the main frame 1 by eye bolts 17. .

Further, a pair of left and right telescopic link strippers 20, 20 are provided between the front link 9 and the rear frame portion 4, each of which is comprised of a cylindrical portion 18 and a shaft portion 19 slidably fitted into the cylindrical portion 18.

Those link strippers 20.20 are attached to each link 9,10
The cylinder part 18 is rotatably supported by the front link 9 and the shaft part 19 is rotatably supported by the rear frame part 4 by shafts 21.

A protection plate 22 is attached between the rear links 10, 10 to protect the practitioner when the spring 16 comes off.

The rear frame portion 23 of the push frame 12 is covered with a mat 24 for protecting the shoulders of the practitioner, and handles 25 bent downward are attached to both side frame portions 13.

Reference numeral 26 denotes a pair of left and right reinforcing members that connect the front frame portion 2 and both side frame portions 3.

When practicing scrum using the above training machine, the second
As shown in the figure, the left and right practitioners T in the first row press their shoulders against the mat 24 of the frame 12 and grip the handle 25 with their right or left hand.
The practitioner in the center puts his shoulders on the mat 24 in the same way and joins shoulders with the practitioners on the left and right sides.

Furthermore, after that, two practitioners in the second row and three practitioners in the third row form a scrum and push the push frame 12 in the forward arrow direction α against the tensile force of the spring 16.

If the left and right pushing forces are unbalanced, the main frame 1 will swing to the left or right with respect to the column 5, and this will be immediately apparent.

In this case, the pushing forces on the left and right sides are balanced by rearranging the practitioners.

If the tensile force of each spring 16 is insufficient for the pushing force, one or two practitioners may sit on the push frame 12 to supplement the tensile force of each spring 16.

As described above, according to the present invention, if the eight people required for Scrum gather together, they can practice Scrum, and since it is small and simple, it does not take up much space, so it can be installed even in narrow spaces. .

Furthermore, the pushing force can be measured based on the extension force of each spring, and since the main frame is swingable relative to the support, imbalances in the left and right pushing forces can be immediately detected, and it is possible to easily change the positions of the practitioners. This allows you to balance the pushing forces on the left and right sides and practice scrums correctly.
