The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:
Consult Fig. 2, the embodiment of the utility model chair tool comprises: chair rack device 1, one are installed in the cushion 2 on this chair rack device 1, and a back cushion 3 that is installed on this chair rack device 1 and is positioned at the back side top of this cushion 2.
This chair rack device 1 comprises two foot rests 10 that lay respectively at the left and right sides.Foot lever 102 behind preceding foot lever 101 that said foot rest 10 has respectively that the top articulates each other and one.This chair rack device 1 also comprises two first side pipes 11 that are installed in respectively on the said preceding foot lever 101, and two second side pipes 12 that are installed in respectively on the foot lever 102 of said back.Said second side pipe 12 is to be articulated in said back foot lever 102 and the oblique extension towards the back upper place respectively, and is positioned at the back side top of said first side pipe 11.
This cushion 2 comprises two first keepers 21 that are connected with said first side pipe 11 respectively, and a cushion body 22 that is positioned at 21 of said first keepers and connects said first keeper 21.
The structure of this back cushion 3 and this cushion 2 are roughly the same; The position of just installing is different; It comprises two second keepers 31 that are connected with said second side pipe 12 respectively, and a back cushion body 32 that is positioned at 31 of said second keepers and connects said second keeper 31.
Consult Fig. 3, said first side pipe 11 defines one first draw-in groove 111 respectively.First connecting portion 211, one that said first keeper 21 has this cushion body 22 of vicinity respectively is away from this cushion body 22 and embed first fastening block part 212 of first draw-in groove 111 slippingly, and consubstantiality is formed at first elastic portion 213 of 212 of this first connecting portion 211 and this first fastening block parts.This cushion body 22 has two first junction surfaces 221 that lay respectively at the left and right sides, and said first junction surface 221 is that hot melt is fixed in said first connecting portion 211 respectively.
Consult Fig. 4, said second side pipe 12 also defines one second draw-in groove 121 respectively.Second connecting portion 311, one that said second keeper 31 has this back cushion body 32 of vicinity respectively is away from this back cushion body 32 and embed second fastening block part 312 of second draw-in groove 121 slippingly, and consubstantiality is formed at second elastic portion 313 of 312 of this second connecting portion 311 and this second fastening block parts.This back cushion body 32 has two second junction surfaces 321 that lay respectively at the left and right sides, and said second junction surface 321 is that hot melt is fixed in said second connecting portion 311 respectively.
In the present embodiment; Said first elastic portion 213 and said second elastic portion 313 all are to be ups and downs wavy structure; But when implementing not as limit; As long as have elastic-restoring force, it is flexible to let said first connecting portion 211 and first fastening block part 212, said second connecting portion 311 and second fastening block part, 312 flexible ground extend respectively, and have enough toughness not easy fracture get final product.
Consult Fig. 2, Fig. 3 and Fig. 5, this chair rack device 1 also comprises two first block pieces 13 that can be installed on said first side pipe, 11 front ends respectively.During the assembling of the utility model chair tool; Said first keeper 21 of these cushion 2 left and right sides is aimed at said first side pipe 11 respectively; First fastening block part 212 of said first keeper 21 is embedded in said first draw-in groove 111 on axial slip ground respectively; Again said first block piece 13 is covered on said first side pipe, 11 front ends respectively,, prevents that it breaks away from said first side pipe 11 to front slide with said first keeper 21 of block.Because the assembling mode of this back cushion 3 and said second side pipe 12, roughly the assembling mode with this cushion 2 and said first side pipe 11 is identical, so no longer specify at this.
In sum; On making; Said first side pipe 11 and second side pipe 12 all are simple structures and make the aluminium section bar of moulding easily; Need the said hook part 421,431 of wearing be welded in respectively and saidly take side lever 42 and lean against side lever 43 (as shown in Figure 1) unlike in the past chair tool, so the utility model is comparatively easily simple on making.In addition, 312 of said first fastening block part 212 and second fastening block parts need axial slip ground embed said first draw-in groove 111 and second draw-in groove 121 respectively, can accomplish this cushion 2 respectively, this back cushion 3 is connected with this chair rack device 1, comparatively easy saving time in the assembling.
In the use; Because of said first junction surface 221 and second junction surface 321 are that hot melt is fixed in said first connecting portion 211 and second connecting portion 311 respectively; Has the firm characteristic that is difficult for disengaging; And said first elastic portion 213 and second elastic portion, 313 high resilience restoring forces and enough toughness, can prevent respectively that said first keeper 21 and second keeper 31 from receiving occupant weight and pullling and rupture, therefore can possess preferable security.
