Pretty and easy to make, removable blinds find their place as soon as spring arrives. Under the pergola, they filter the sun's rays nicely and add to the pleasure of the lunches on the terrace.

Make yourself mobile blinds for a pergola

Aesthetic and economical, this fabric protects a removable wooden pergola from solar radiation (System D n° 703), but could very well, thanks to the system implemented, be installed on another support. Each veil slides on two cables stretched along the joists with hooks which, chosen to be removed easily, are attached to bamboo rods slipped into the fabric to give him hold.

A mobile system

The pergola consists of two series of seven joists assembled mid-wood on three main beams. Each sail covers the space between three joists, 50 cm apart from one axis to the other. There are therefore three bays of cloth one meter wide.
Rigidized by bamboo whales, the sails slide on plasticized iron strands stretched along the length of the pergola, the load being taken up under the median beam by screws with closed eyelet.

A realization within the reach of all

The assembly presents no difficulty. The twelve anchors (four per span) are cut in an aluminum U (section 20 x 20 mm) cut with a hacksaw in lengths of 5 cm. The holes are made before the profile is cut: at 10 mm from the cutting marks, two Ø 5,5 holes are made in the bottom of the groove and on each of the wings.
The supports are fixed by TR Ø 5 wood screws on the underside of the beams and directly above the joists. A line is stretched to materialize the line and identify the locations of the eye bolts on the center beam.
The threads, knotted at one end, are fixed to each other in a small garden tensioner chosen in plasticized finish (only one tensioner per anchoring support). The threads are tight, but without excess: the weight of the sails is reduced.

Bamboo whales

Used to stiffen sails, whales are bamboo stakes bought in garden centers. Lightweight, rigid, weatherproof and cheap, bamboo has been preferred over wooden slats, which remain an alternative. The plastic, on the other hand, must be discarded because it lacks holding (bending).

At 10 mm from each end of the bamboo stem, a small V-notch is cut. It avoids the sliding of the nylon tie (a cable tie) used to attach a carabiner 30 mm that will hang the bamboo wire. Orient the flexible fasteners towards the inside of the whale: the operations of assembly and disassembly will be facilitated. Count a whale every 50 cm of awning and add a unit for the end wand.

Small sewing

The current canvases are cotton, ecru or color "big complexion" to resist UV. Polyester fabrics offer greater strength and dimensional stability. If you opt for polyester, take the same material for the sewing thread.
For six blinds each fitting a span of 2.20 m, a coupon of 15 x 1 m was purchased. The surplus fabric allows the making of gussets and the formation of waves that give an impression of lightness.
The strips being cut at 2.50 m, the edges are hemmed. At the ends, prick the fabric to form a 3 cm gusset. Fold each accordion piece to obtain five sheets of fabric about 50 cm. Make a seam 3 cm from the folds to form the intermediate gussets.

Setting up

Once the blind is equipped with its whales, hang it on the wires, one whale after another. The carabiners of the end whales engage in the holes on the anchors. Just clear them to fold the blinds at night or when the rain threatens.

The median beam receives closed eye bolts screwed into the alignment of the supports. These lag bolts take over the load of the blinds and relieve the wire.

Each bracket serves as an anchor point for a wire and wire tensioner. The latter is fixed by a bolt and a nut. The thread tension is adjusted by turning the tensioner shaft.

A carabiner of 30 mm is locked in the hollow of each notch by a plastic cable tie. It is he who ensures the sliding of the sails on the wire.

When the karabiners are in place at each end of the bamboos, insert them into their gussets along the length of the six blinds.
