At the heart of any upholstered furniture, be it a bed or mattress is a spring block.It provides elasticity and softness of the design.From what kind of structure should depend on the performance of the headset or the bed.
in modern production occurs as a mattress on the spring block, and with fillers.So the choice for consumers.
At the heart of many of today's mattress is a spring unit, which can in some cases provide orthopedic support body.The current production is two options:
- spring block "Bonnel";
- independent spring block.
Springs "Bonnel"
From the category of economical blocks.In the standard it has 4 double-cone spring interturn form.They are installed in a row, and are used for connecting the coil in the upper and lower parts.
Such spring blocks for upholstered furniture are named blocks of continuous weaving.Immediately it is worth noting the point that in this model there is no orthopedic effect.This is due to the fact that all springs are connected in a single unit, i.e. by deformation of one element folded all adjacent springs.
If the domestic firm is engaged in the production, the cost of such a product will vary 1000-10 000.People who have any problems with posture, joints and spine in general, this option is absolutely contraindicated.Such a spring unit will not get better, even if it is used together with an expensive filler.
Independent springs
This option mattresses are much better, as though the production of spring units of this category is similar to the way the produced spring block "Bonnel", yet the diameter of the elements of their much smaller.In this embodiment, the maximum size of the circle, is only 20 mm, while not more than 8 turns pieces.Thus, one square meter of such a block is from 250 to 1200 spring.Form elements reminiscent of the barrels.
Pillow effect is achieved by placing each coil in a separate case that ensures their independence from each other.Accordingly, when there is exposure to a separate spring adjacent unaffected, allowing more evenly distribute the load on the entire surface.
Pocket Spring mattresses
spring block Pocket Spring - the system of independent springs.This design is used in all modern mattresses that allows you to choose the bed in which there is no basis under the mattress.Only needed a special attachment at the corners, which will be to fix the product.There is also a framework which provides stiffness and resiliency while providing loads.These mattresses can be used as a separate couch by equipping them with special furniture legs.The outer lining material - jacquard.
idea occurrence spring block
element such as a spring, was invented long ago, but to combine them into a single system came up with the Italian military.A similar design was used in Italy when the sappers deactivated landmines in the fields.After the block of independent spring configuration allows you to evenly distribute the load of the human body over the entire surface, rather than on one specific site.
But not everyone agrees with this legend, although it is documented at the time.
Features springs
Depending on the size of spring mattresses secrete several categories:
1. If the coil has a diameter of 50-60 mm, the spring unit called TFK butene, S-500 or EVS500.In this embodiment, each element has its own cover.The average density is 220-300 per square springs.meter.Domestic products are cheaper than imported counterparts 2-3 times since the last delivery fairly laborious.And all of the fact that these items can not fold into a roll.
2. Springs 20-40 mm are called S-1000 and S-2000.The small size allows you to increase the number of springs per square meter, so it is up to 500-1000 pieces.This design is called anatomic as able to more clearly repeating silhouette.In addition, such a spring allows to distribute the load evenly on all surface areas.Compared with the previous version will be higher stiffness, thus expanding the weight category of people.
double spring
There are universal mattresses, which combine spring of small and large diameter.They are called "the spring in the spring."In this embodiment, a narrower element is placed inside a larger.In this latter is somewhat less rigidity than the first.
If this box is the average load, the deformed only the big spring.As soon as the weight increases, the work will take and small.This option is great for those who have a spouse the difference in weight of more than 40 kilograms.
Performance of the springs
Since mattresses today are often produced on order, manufacturers are offering customers to consider the following options:
1. Strengthening .In this case, the spring unit is designed for those who are overweight.The design may be enhanced by the creation of a double wire or staggered springs.In the second case, they are more closely adjacent to each other.The mattresses, "Bonnell" is due to the strengthening of the foam inserts into spirals.
2. Zone box spring. With this structure, there are separately isolated zones which are individually rigidity.They are arranged in accordance with the human anatomy.Since every part of the body has its own weight when the person lies down on what a surface is unequal loading on each site.Therefore, the body is maintained in the correct form, need different stiffness.
zones may be 3, 5 or 7, depending on the model of the mattress.But this option is not available for all manufacturers.
3. Half-hearted blocks. One longitudinal halves has stiffer springs, and the second - a more soft.This option is useful for those couples in which one likes to sleep on a firm, and the other - on the soft.
Fillers for mattresses
In most cases, the spiral inside have a soft upholstery.This is to ensure that the product is not strongly deformed when sitting man on the edge.Inside the mattress creates a box where there are upper and lower soft layer.
Depending on what material is used for such purposes will be determined by the properties of hardness.For example, more stringent design uses coconut and soft the basis of a latex or polyurethane.Some manufacturers use a combination of these materials, which is extremely convenient, as the product is obtained medium hardness.
little about the couches
for sofa designs using the same system as the mattress.The only thing in this case is given more attention - a filler as the sofa is still often used for sitting, not lying.But this does not mean that it should be less comfortable.
best option is when the furniture has a filler, and a spring.Today is considered the best duo polyurethane foam and box spring for a sofa.The price of these products somewhat high, but it's all because of this furniture has orthopedic effect.The structure of the polyurethane foam has a good ability to recover, with no restrictions on weight.Also, a filler is well suited to those who suffer from allergies or asthma.
Another fairly popular and high-quality filler - latex.Since it is generally first-class material, the price of such products would be even higher.If you purchased a quality product, you can not be afraid that during intensive use the light come out of the spring.If observed during production technology, between the spirals and the upper shell is sufficiently many layers of different materials that hold the spring in place.
Yet in the sofas are more common spring blocks it with dependent spirals.
Species blocks
Blocks springs may be of the following types:
1. FRAMELESS .This type consists of double cone springs and spirals that connect them.This type is applicable to the headset, where there are only one or two soft side, which are formed at the expense of the unity of sustainable flooring boards.
2. Unilateral .In this embodiment, the springs have a metal frame, which surrounds the whole working plane.He serves as the framework for the edges of which are fixed soft flooring materials.If the unit is assembled by hand, then this element helps to further pursue the necessary dimensional stability (block and soft elements).This option is applicable to soft-sided cells.
3. Bilateral .This configuration is characterized by the number of frames blocks, ie there are two of them.Accordingly, the scope of them where the furniture has two soft side.
Regardless of the type of block used in their base a spring made of stainless steel wire, to which, in turn, taken carbon steel.With the right technology, each element lends itself to leave.This is done in order to stabilize the metal in its dimensions and hardened, or during use of the product will appear on the surface of hillocks due to the fact that the spring unit is strongly deformed.
production technology
spring units for mattresses and upholstered furniture can be assembled using automated equipment or by hand.Immediately it should be noted that in the first case the products are of a higher quality than in the second.
manufacturing spring units manual assembly has the following steps:
1. To make the double cone springs, first make basic edits wire, after which it is wound on a special form to get yourself spiral.Then twist nodes at major turns, and only if the elements lend themselves to heat treatment.
2. The next step is the creation of fastening spirals, which again ruled wire, and then carry out beaming.
3. To make the frame, the right rolled tape or wire.Then give it the desired shape and connect all the ends together.
4. After connecting spiral coils springs fixed support for creating frameless unit.
5. Also manufactured shackles.This is called stamping.
6. Further, all connected into a single structure, ie frame and springs are combined by means of staples.
course, every step is thoroughly tested.But during manual assembly still there is the human factor, which sometimes affects the quality of the construction unit.
As for automated production, the plant units have a series of G-65 / SW.These machines carry out all the work by yourself on a pre-set parameters.
also not the last role played by the manufacturer itself.After all, a well-known brand will always be the maximum to keep its brand, trying to create products of the highest quality.Therefore it is necessary to give priority to well-known manufacturers, who have already successfully established themselves in the market.
