Description

A kind of Frame of sofa structure-improved

Technical field

The utility model relates to a kind of sofas, more particularly to one kind to have structure improved Frame of sofa.

Background technique

It is comfortably experienced brought by furniture with the improvement of living standards, people start more to pursue, sofa is as people Live in important household items, people require it also higher and higher.Currently, common Frame of sofa is all utilized in wood Connect several S type springs of parallelly distribute on frame material, then by each S type spring and elastic band and it is wrong connect, then S type spring with One layer of net is followed closely again on the layer of elastic band composition.Such skeleton elasticity is poor, also insecure, and is easy recess over time and becomes Shape cannot provide comfortable experience, it is therefore necessary to be improved for user.

Utility model content

The purpose of this utility model is that proposing a kind of with structure improved Frame of sofa, sound construction, with steady Qualitative strong, elasticity is good, is unlikely to deform, durable, comfortable experience can be provided for user, to overcome in the prior art It is insufficient.

For achieving the above object, the utility model adopts the technical scheme that

A kind of Frame of sofa structure-improved, it is characterised in that: including bottom surface, frame, spring layer and layer of the bandage, the bullet Spring layer is located at lower portion, and spring layer includes waist drum spring layer and S type spring layer, and S type spring layer is located above waist drum spring layer, Waist drum spring layer includes several waist drum springs perpendicular to bottom surface, and S type spring layer includes several S type springs being parallel to each other, The adjacent S type spring of any two is in the same plane, and S type spring layer is parallel to bottom surface, the waist drum spring top and S type Spring connection, the layer of the bandage are parallel to bottom surface and are located above S type spring layer.

Preferably, the frame includes crossbeam, stringer and the basic framework that bottom surface surrounding is arranged in, the crossbeam and vertical Respectively in parallel and bottom surface, and crossbeam and stringer are mutually perpendicular to beam, and the both ends of crossbeam and stringer are connect with the basic framework, institute It states stringer to be located above crossbeam, the longitudinal and cross beam is supported by pillar and connected, and the strut height is lower than waist drum spring Highly.

Preferably, the waist drum spring bottom is connect with crossbeam, and S type both ends of the spring is connect with basic framework.

Preferably, the S type spring layer further includes steel wire, and the steel wire is vertical with S type spring, every two adjacent S type Spring is fixed after connecting with steel wire, and the both ends of steel wire bypass the S type spring close to frame, forms a circuitous configuration.It is described Elastic connection between steel wire and basic framework.

Preferably, the waist drum spring is swelling-waist shape, and both ends diameter is greater than mid diameter.

Preferably, layer of the bandage includes several parallel and/or interlaced bandage, and bandage both ends are connected with basic framework.

Preferably, the steel wire outer surface is wrapped up in paper bag.

Compared with the prior art, the advantages of the utility model are: having carried out improvement design, the cross of addition to Frame of sofa Beam, stringer, so that entire Frame of sofa more fastness, the sofa that the vertical waist drum spring layer of the S type spring of addition greatly increases Elasticity, extend its service life, increase its comfort level, and used steel wire to fix S type spring and waist drum spring, greatly Stability is improved greatly, so that sofa cushion will not be deformed because of long-term sit.

Specific embodiment

It is refering to fig. 1 a preferred embodiment of the utility model, a kind of Frame of sofa structure-improved, it is characterised in that: packet Bottom surface 1, frame, spring layer and layer of the bandage are included, the spring layer is located at lower portion, and spring layer includes waist drum spring layer and S Type spring layer, S type spring layer are located above waist drum spring layer, and waist drum spring layer includes several waist drum springs perpendicular to bottom surface 2, S type spring layers include several S type springs 3 being parallel to each other, and the adjacent S type spring 3 of any two is in the same plane, S Type spring layer is parallel to bottom surface, and 2 top of waist drum spring is fixedly connected between S type spring 3 by fixing buckle 4, the layer of the bandage It is parallel to bottom surface and is located above S type spring layer.

Frame includes crossbeam 5, stringer 6 and the basic framework 7 that 1 surrounding of bottom surface is arranged in, and the crossbeam 5 and stringer 6 divide Not in parallel with bottom surface 1, and crossbeam 5 and stringer 6 are mutually perpendicular to, and the both ends of crossbeam 5 and stringer 6 can be by flat nail and described basic Frame 7 connects, and the stringer 6 is located at 5 top of crossbeam, the stringer 6 and crossbeam 5 by the support connection of pillar 8, is actually using When the utility model, pillar 8 can be fixedly connected with 5 stringer 6 of crossbeam respectively with flat nail, 8 height of pillar is lower than waist drum bullet The height of spring 2.2 bottom of waist drum spring is connect with crossbeam 5 by fixing buckle 4.3 both ends of S type spring are passed through and are arranged basic Spring clip 9 on frame 7, then followed closely spring clip 9 in basic framework 7 with flat nail, so that S spring 3 is connect with basic framework 7.S Type spring layer further includes steel wire 10, and the steel wire 10 is vertical with S type spring 3, every two adjacent S type spring 3 with steel wire 10 Series connection, by fixing buckle 4 that steel wire 10 and S-shaped spring 3 is fixed, the both ends of steel wire 10 bypass the S type spring close to basic framework 7 3, form a circuitous configuration.Elastic connection between steel wire 10 and basic framework 7, for example, by short bandage 11 1 consolidated by flat nail It is scheduled in basic framework 7, passes through simultaneously wrapped wire 10, other end is connect by flat nail with basic framework 7, it can also be with spring Short bandage 11 is replaced Deng other elastic devices.Waist drum spring 2 is swelling-waist shape, and both ends diameter is greater than mid diameter.Layer of the bandage It is distributed or is interspersed including several parallel and/or interlaced bandage 12, such as 12 parallel interval of bandage.12 liang of bandage End makes bandage 12 be connected with basic framework 7 by flat nail nail in basic framework 7.It is wrapped up in paper bag 10 outer surface of steel wire.

In addition, reinforcement structure 13 can also be arranged on the inside of its quadrangle to improve the firmness of frame.

The Frame of sofa of the improved design is not only easier to I& M, and structure more fastness, elasticity is good, effectively Comforts of use are improved, also, sofa cushion will not be deformed because of long-term sit, service life substantially extends.

This skeleton can also be used for mattress, in the similar structures such as cushion.

It should be pointed out that as described above is only the preferred embodiment to explain the utility model, it is not intended to evidence To make limitation in any form to the utility model, therefore it is all have make under identical utility model spirit in relation to this reality With novel any modification or change, it should all be included in the scope that the utility model is intended to protection.
