Modern orthodontic structures - dental brackets: principle of operation, features of installation and use


Accessories for sofas - wheels and supports

Depending on the mechanisms of transformation of sofas, there are two types of support:

  1. Wheels
  2. Legs

Wheels for sofas come in various shapes and locations:

  1. Large
  2. Average
  3. Little ones
  4. Side
  5. Inside the bracket
  6. Above

Do not confuse wheels with rollers. Furniture accessories for a sofa wheel are a support on which the unfolded sofa rests. And furniture fittings, rollers for a sofa, are mechanisms that help you unfold and fold the sofa.

The wheels are made of durable polyurethane. When choosing them, you should pay attention to:

  1. No cracks
  2. Easy scrolling

The rollers are made of metal and run on a special sleeper

The legs come in different shapes and thicknesses and are made from different materials (wood, plastic, metal).

DIY sofa backrest installation

Sofa assembly: 1—sidewalls; 2—back frame; 3—side panels of the base; 4—base frame; 5—frame of the retractable block; 6—sheathing (hardboard); 7—frame reinforcement corner; 8—bolt with nut; 9—screws; 10—wheel bracket; 11—furniture wheel; 12—wheel axle; 13—piano loop; 14—stopper.

The back of the sofa is assembled with your own hands only after everything is prepared, including a drawing of the future design. This is important to take into account, since without precise dimensions it is impossible to make a beautiful and attractive back.

You need to start by preparing a template and markup. The plywood is placed on a horizontal surface suitable for cutting. According to the prepared diagram, the outline of the future backrest is applied to its surface; it is important to double-check all dimensions.

The outline is drawn with a simple pencil, cutting should be done strictly along the lines, choosing a cutting blade of the required size. Typically, medium-thick plywood is used for such work; there should be no problems with cutting.

If the backrest is rectangular in shape, then it is important to ensure that its length matches the dimensions of the sofa. It should not be smaller or noticeably larger. It is best to give the back beautiful, smooth contours.

To do this, you can make semicircular cutouts in the upper corners. To do this, it is best to use a template so that all the cutouts are the same shape. After this, the surface of the cuts is treated with sandpaper. All dust must be removed after this, after which you can continue working. At the next stage, you can upholster the backrest; for this, fabric and foam rubber are used.

You must immediately take into account what the edge will be like, there are 2 options possible:

  1. In the first case, the edge will also be soft, the foam rubber will be attached close to the end parts.
  2. In the second case, it is necessary to retreat a small distance from the edge; it will be covered with fabric. Usually a beautiful decorative frame is used for decoration, which hides the edge and gives the sofa more attractiveness. Such frames can be different, ranging from carved wood to fabric overlays.

Foam rubber is attached first; PVA glue is used for this; you can use self-tapping screws for reliability. Then you need to cut the fabric, not forgetting about the allowances that will be wrapped on the wrong side. You need to prepare 2 pieces of fabric. One of them is used for the front lining, and the second for the back, which is adjacent to the wall.

The fabric is fastened with furniture staples; this process must be carried out carefully so that the upholstery is stretched evenly and does not wrinkle . After the back is ready, you need to start attaching it. It all depends on which option is chosen. The backrest can be fixed directly to the bed frame, to the wall, or have a combined fastening method.

Most often it is the latter that is used, as it is more reliable. The backrest is fixed to the frame on the back of the sofa, and it will be attached to the wall using special metal hinges and anchors. This allows heavy and large panels to stand stable and level.

Staples and Braces - What's the Difference?

People often confuse brackets with braces, but these designs are very different from each other. Despite the fact that these systems are used for the same purpose, they are characterized by many fundamental differences.

Braces are an orthodontic device that consists of many parts and elements interconnected and guaranteeing effective correction of defects in the dental system. This is a non-removable design that usually has to be worn for at least 1-1.5 years. A brace is a removable corrective device that is put on the teeth and encircles them. It does not have so many elements - it is simpler to implement. This option is more often used to correct the position of teeth in childhood and adolescence.


Braces for teeth

It is worth noting that treatment using braces will cost the patient significantly more. On the other hand, braces often successfully cope with complex clinical problems that are beyond the capabilities of removable corrective systems.

Contraindications

Treatment of ingrown toenails with plates and staples cannot always be recommended to patients. The methods have a number of contraindications that should not be forgotten:

1. Fungus. There is a risk of infection of healthy nail plates;

2. Diabetes;

3. Children under 6 years of age.

Plates and staples for treating ingrown toenails are popular in medical practice. They do not have an immediate effect, the process is gradual, the nail takes on the desired shape, and relapses are extremely rare. The success of the procedures depends on several factors: a qualified doctor and high-quality material. If both conditions are met, you can forget about the problem of ingrown toenails.

What to do if a bracket gets stuck

When using a construction stapler, a problem such as breakage of the staple inside the receiver often arises. Fasteners often become bent or stuck in the outlet, causing many problems. To restore functionality, you will need to completely remove the magazine with staples. Professional models have a removable receiver, so repairs will not take much time.

First of all, you should open the metal plate and take out the spring. Next, in the middle of the stapler you need to find an iron part and tightly clasp it with your fingers. This will allow you to remove the entire magazine and remove the jammed bracket.

Reassembling the tool does not require much effort: the removed magazine is put back in its original place, after which a characteristic click should sound. Next, all that remains is to return the spring to the groove.

If you are using a power tool, be sure to adjust the special screw when using the rough material to check. During this stage you need to rotate it from minimum to maximum. If the bracket is well secured from the first shot, proceed to work on the “finishing” part. In other cases, the procedure will need to be repeated.

A furniture stapler is a universal construction device that is suitable not only for upholstery activities, but also for more complex work. If you use this tool correctly, it will serve you for a long time and with high quality.

Difficulties in reupholstering upholstered furniture

Damage to a sofa or other upholstered furniture can vary in severity. Depending on the existing injuries, a different range of work is required. Here's what can happen to your furniture:

  • Only the fabric became unusable (cats tore on the armrests, for example), i.e. There are no dips in the soft part or protruding parts. Then everything is more or less simple and you can get by by replacing the upholstery fabric. The simplest case is if you need to replace the fabric

  • There are some dents in some places . This damage is caused by wear and tear on the components that make up the upholstered part of the sofa. Depending on the degree of damage and the design of the sofa itself, it may be necessary to replace padding polyester and other underlying layers. In more severe cases, repair of spring blocks, if any, or foam rubber/silicone if the sofa is spring is required. If the upholstery looks quite good, it can be washed and used again.
  • Dim in the bottom of the seat. Sometimes, due to high loads, the springs pierce the bottom of the frame. This happens most often if it is made of fiberboard. In this case, you will have to disassemble everything, remove the spring dock, replace the fiberboard (preferably with plywood). This sufferer needs more than just replacement upholstery...

  • Damage to the frame . One of the most unpleasant things is cracks in the frame bars. The sofa will have to be completely disassembled, the broken bars replaced, and then everything restored. This is a complete reupholstery of the sofa. Essentially, you're building a new one.

So reupholstering a sofa can involve different jobs. From simply replacing the upholstery to a complete renovation, including part of the frame. The most troublesome part is with the spring blocks. This is long and painstaking work. If the “historical accuracy” of your furniture is not important to you, it is easier to replace a failed spring block with foam rubber or (better, but more expensive) furniture silicone. If everything is done correctly, the sofa will become even more comfortable: incorrectly tightened springs cause a lot of inconvenience.
