An outdoor post for a sports equipment manufacturer: rim height adjusts from 1.8 to 3.05 m, the backboard sits on consoles, and the whole structure stands on an embedded part cast in concrete. The package: 32 drawing sheets and a product passport.
The client was a sports equipment manufacturer. They needed a production outdoor post with adjustable rim height: from kids' height to the standard 3.05 m on one and the same post.
For a manufacturer that means a full package rather than one drawing: working drawings for the shop, a passport for the buyer and renders for the catalogue, so the post can be sold before the first batch is made.
A backboard with a rim is a load at the end of a long lever. It has to go up and down, and in every position the post has to take the game.
Backboard overhang. The consoles carry the backboard far from the post: the product is 2535 mm long in plan and 1100 mm wide. The moment from the board's weight and ball impacts ends up in the post base.
Variable geometry. The height changes, but the board must stay vertical and free of play in every position.
Stability. A stability calculation was run and the counterweight optimised, so the post neither tips over nor weighs more than it needs to. Backboard overhang and shot dynamics were accounted for separately.
Outdoors. For sports equipment the main constraint is not strength but vandal resistance and safety: no sharp edges, fasteners that can't be undone with an ordinary spanner, margin for loads nobody planned.
Height is changed by a parallelogram: two pairs of consoles hinged between the post and the backboard frame. The board moves up and down while staying vertical, and a lift holds it in position.
The post is a 160 × 160 × 5 mm hollow section on a base plate with stiffening ribs
Consoles made of 100 × 60 × 4 mm tube pivot on pins with bushings — the hinge runs on a bushing, not on a hole in the tube
The backboard frame, made of 60 × 60 × 3 mm tube, carries the board and the rim
A lift on the post moves the board between positions and locks the height
The base is an embedded part with a rebar cage cast in concrete, with anchors and ISO 4032 M20 nuts
Overall size per passport: 1100 × 2535 × 4347 mm, mass 189 kg. Hollow sections 160×160×5, 100×60×4 and 60×60×3 mm, cold-rolled plate, bushings in the hinges, standard M20 nuts on the embedded part's anchors.
Besides the adjustable post, the portfolio has a fixed version, and the drawings section has a separate set for a post without a backboard (РПКД.18.00.000, 17 sheets) with its own passport.
The set runs from the assembly drawing with its bill of materials down to every part: post, consoles, backboard frame, embedded part. The passport is a separate document for the buyer with dimensions, mass and components — it is what travels with the post to the site.
The manufacturer got a full package for a production item: 32 drawing sheets from the assembly view down to each part, a passport, and catalogue renders — 16 of the adjustable post and 9 of the fixed one.
The parallelogram and the embedded base aren't tied to one particular board, so the same scheme can be carried over to other sizes without redesigning from scratch.
