Description
Technical field
The utility model relates to sofa field, particularly a kind of sofa frame.
Background technology
In daily life, sofa is one of furniture of commonly using the most of people, and sofa is primarily of sofa frame and the cushioned portions composition wrapping up in sponge with cloth or suitcase.Timber compares the material being widely used for manufacturing sofa frame in the market, in order to increase comfort level and resilience, generally at sofa base, serpentine spring is installed, the metal framework sofa of prior art can only increase comfort level and resilience with elastic cord connecting frame, but the fastness of sofa base is poor.Some improvement opportunity are had one deck steel mesh to be set as sofa base bracing means to improve the fastness of sofa base at sofa base, but receive the obstruction of steel mesh when deformation occurs in the serpentine spring effect of being under pressure, steel mesh reduces comfort level and the resilience of serpentine spring.
Utility model content
Mirror is with this, and the purpose of this utility model is to provide a kind of sofa frame, neither affects comfort level and the rebound performance of serpentine spring, turn improves the fastness of sofa base.
The technical solution of the utility model is achieved in that
A kind of sofa frame, comprise base and backrest, base both sides are provided with handrail, and base is provided with serpentine spring and girth member, described girth member is positioned at the below of described serpentine spring, described girth member be two ends be connected to described base and middle part to recessed curved girth member.
Further, described girth member be two ends be connected to described base and middle part to recessed curved reinforced pole, curved gusset plate or curved reinforcing pipe.
Further, the junction of described girth member and described base is provided with bearing.
Further, be provided with can the returning device of self-return in the junction of described girth member and described base.
Further, described returning device is return spring.
Further, described base lower end is provided with sofa leg, and described sofa leg is made up of 3 U-shaped unit, and wherein the U-shaped unit groove of both sides horizontally set is back-to-back distribution and is connected to the both sides of middle U-shaped unit.
Further, the junction of described sofa leg and described base is respectively equipped with screw installing hole.
Compared with prior art, the beneficial effects of the utility model are:
The base of the utility model sofa frame is provided with curved girth member, neither affect comfort level and the rebound performance of serpentine spring, turn improve the fastness of sofa base, sofa is comfortable durable, adopt curved girth member of the present utility model that sofa base entirety can be made to save the sponge of at least 10 cm thick, greatly reduce production cost;
Sofa base lower end is also provided with sofa leg, and two side direction middle concaves of described sofa leg are to design, and sofa leg can prevent people foot when sofa from being wounded by sofa leg, adopts U-shaped pin and floor contact, reduces floor pressurized, and protection floor is impaired;
In addition, girth member and sofa leg can be packed up as required and put down, and when packing up girth member and sofa leg, can save very large parking space, or save transportation and packing space, save packed and transported and take, and convenient carrying.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only preferred embodiment of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation under Fig. 1 packs up girth member and sofa leg state;
Fig. 3 is the structural representation of other embodiments of the utility model.
In figure, 1 be base, 2 be backrest, 3 be handrail, 4 be serpentine spring, 5 be girth member, 6 be sofa leg, 7 be screw installing hole, 8 for returning device.
Detailed description of the invention
In order to better understand the utility model technology contents, a specific embodiment being provided below, and by reference to the accompanying drawings the utility model being described further.
See Fig. 1, the utility model sofa frame comprises base 1 and backrest 2, and base 1 both sides are provided with handrail 3, and base 1 is provided with serpentine spring 4 and girth member 5, girth member 5 is positioned at the below of serpentine spring 4, described girth member 5 for two ends be connected to base 1 and middle part to recessed curved girth member.
Serpentine spring 4 refers to that the steel wire forming spring body is continuous print S shape structure.
In the utility model, girth member 5 have employed two ends be connected to base 1 and middle part to recessed curved reinforced pole, in other embodiments, girth member 5 can also for two ends be connected to base 1 and middle part to recessed curved gusset plate or curved reinforcing pipe.
It should be noted that, in order to see bottom girth member 5, figure in only draw part serpentine spring 4.The steel pipe on base 1 both sides of sofa frame can be pulled to inner side because serpentine spring 4 is under pressure when effect, girth member 5 of the present utility model is curved design, neither affect comfort level and the rebound performance of serpentine spring 4, turn improve the fastness of sofa base 1, structure is simple, save sponge material cost, reach the comfortable durable excellent effect of sofa.
In the present embodiment, base 1 lower end of sofa frame is also provided with sofa leg 6, and sofa leg 6 is made up of 3 U-shaped unit, and wherein the U-shaped unit groove of both sides horizontally set is back-to-back distribution and is connected to the both sides of middle U-shaped unit.
Before and after sofa leg 6, two side direction middle concaves are to design, can prevent people foot when sofa from being wounded by sofa leg, and adopt the U-shaped pin contact floor of horizontally set, reduce floor pressurized, protection floor is impaired.
In addition, girth member 5 is provided with bearing with the junction of base 1, make girth member 5 can within the scope of 0-180 degree rotary moveable, namely can pack up and put down; Sofa leg 6 is respectively equipped with screw installing hole 7 with the junction of base 1, sofa leg 6 is fixed by screw with the junction of base 1, sofa leg 6 rotary moveable within the scope of 0-180 degree can be made when unloading segment screw, namely can pack up and put down, when installing whole screw, can fastening sofa leg 6 to provide a supporting role.Because girth member 5 and sofa leg 6 can be packed up as required and put down, when warehouse-in is deposited or in transportation, can rotate up and pack up girth member 5 and sofa leg 6 (see Fig. 2, in order to see girth member 5 and the sofa leg 6 of bottom, part serpentine spring 4 is only drawn in figure), to save parking space, or very large transportation and packing space can be saved, save packed and transported to take, and convenient carrying.
See Fig. 3, in other embodiments, described girth member 5 and the junction of described base 1 are also provided with can the returning device 8 of self-return, this returning device 8 can for easy return spring or other there is the assembly of self-return function.When base 1 is subject to the pressure be sitting in from people on sofa, the flexure plane being provided with the girth member 5 of bearing will rotate, rotate within 90 degree or the plumbness of 90 degree according to stressed size, when people leaves sofa, the flexure plane being provided with the girth member 5 of returning device 8 will self-return, and namely the flexure plane of girth member 5 returns to horizontal level state.
