Plyometric Box With 5 Different Heights!

介绍:普利管盒5个不同的高度!

About: Hobbyist, part time college teacher regarding industrial design topics.

I just love to run, specially trail running. Besides training
speed there is another very important factor, strength.

There are several different ways to get stronger legs but one I Iove is box jumping that is why I decided to build one for myself.

设计与其他拼凑的盒子不同,大多数都有3个高度。经过几次设计会议,我提出了这种有5个不同高度的替代方案。主要约束是从单个胶合板上有一个盒子。

The different heights are 40, 50, 60, 70 and 80 cm. I decided to include the specific numbers using homemade laser cut stencils with military ranks, the higher the height, the higher the military rank.

用品:

MATERIAL:

1 plywood sheet (5/8, 3/4 or 15mm)

1-1/2 in wood screws

木材胶水

TOOLS:

Table saw (or circular saw with a guide)

Jig saw

Wood router with a 1/8 Rounding Over Router Bithttps://www.harborfreight.com/carbide-tip-roundove ...

Step 1: Design

There are 8 pieces for this box. I used 15 mm plywood:

A: 70x60 B: 77x57 C&D:77x68.5 E: 60x48.5 F: 57x41.5 G: 60x20 H: 60x37

Wait, what? 15 mm thickness plywood? Yes, that´s what I found with my wood supplier, but don't worry I am also adding a table with the modified dimensions if you have 5/8 or 3/4in material.

Step 2: (optional): Using Different Thickness

Use the table as a reference to make your cuts if you are using 5/8 or 3/4 plywood. The consideration is that the disk kerf is 0.094in.

Use the attached dwg file to see more details and use my number one shop rule,"Check the design three times, measure twice and cut once."

步骤3:最初的削减

Review the design and try to cut all the similar lenghts with the same table saw setup (or fence position) to minimize assembly issues.

Step 4: Assemble the Parts

每4英寸标记边框上的螺钉位置。使用小位具有用于螺钉的预钻孔,并最大限度地减少在组装过程中拆分胶合板的可能性。

使用埋头孔准备孔,以便螺钉头齐平,最终表面对最终用户更好。

第5步:添加手柄

Using the forstner bit and the jig saw cut the handles to ease the jump box movement.

Step 6: Round the Edges

Having rounded edges is a must to protect your legs in case something goes wrong during training.

Remember to remove the screws before routing the edges to avoid bit to metal contact.

第7步:最终组装

Add glue to the wood edges if you desire a stronger box

Step 8: Reinforce the Box

You can strengthen the box using the plywood sheet scrap installing some parts inside at the middle position between sides C and D. You just need to add glue and thats it.

I you prefer to go one step further, add some more wood at the corners, scrap or pallet sections are just great options.

Step 9: Decorate Your Box

I decided to include marks showing the jumping height figures. But, as part of the concept I included some generic military ranks.

I prepared home made stencils using a home laser engraver. You only need to apply some spray adhesive find the position and press against the plywood. Cut the small paper bridges with the utility knife if you like.

只需涂抹光和快速的涂料层。

第10步:使用新的拼接箱

You are ready to go!

The first level can't be used to jump but guess what? It can be used:

- as a step

- to perform triceps dips

- you can do assisted or elevated lunges

- 卧推

- and a lot of other exercises.

Thinks: if you lowered part of one of the L shaped sides, could you get a box with six different levels ?

Nice project. The rank you designated as "Sergeant First Class" is actually "Staff Sergeant". SFC has one more 'rocker' stripe.
