Description

The rail bar structure-improved of stair lifting chair

Technical field

The utility model relates to a kind of rail bar structure-improveds of stair lifting chair, thereon, lower rail bar be solid metal item, can As the corner of stair is bent, and in having directly cut tooth row on the lower rail bar top end face.

Background technique

Traditional household is mostly to rely on stair to reach the floor being intended to, for some handicapped the elderlys or the disabled Scholar wants stair activity relatively difficult, and causes using upper inconvenience.

Therefore, as shown in Figs.1 and 2, go downstairs on handicapped the elderly or physical disabilities' convenience to provide Ladder has stair lifting chair on the market, and rail bar 10 and lower rail bar 11 are hollow metal pipes thereon, the lower rail bar 11 by strut 110 and Tooth row 111 is formed, and is equipped with locating plate 1100 in side, thereon for the welding of tooth row 111.However in assembling, it need to connect respectively Knot is fixed, and is more troublesome inconvenience, and the tooth row 111 is welded in locating plate 1100 outstanding, therefore combination is not firm enough, and If stairway width is relatively narrow, chair lift and opposite wall distance are extremely close, and oppress occupant excessively and uncomfortable, and influence Stair space.In addition, rail bar is all that vertical bar shape can not be bent up and down, so chair lift cannot turn when upper and lower stair, Ye Jiyao At turning in addition one chair lift is set respectively, increases its cost of manufacture, and there is this missing.

Utility model designer is in view of the missing in existing stair lifting chair rail bar use, to keep rail bar steady with seat Consolidation closes and promotes the space of chair lift and stair, is initiating one in line with excelsior spirit as the project of research The rail bar structure-improved of kind stair lifting chair, and then reach enhancing rail bar intensity, improve safety and chair lift can be made with stair Corner turning effect, have comparable practicability.

Utility model content

The rail bar of existing stair lifting chair is hollow metal pipe, it is necessary to support column and tooth row is separately connected, using upper suitable It is inconvenient and obviously there is great missing.

The utility model be a kind of stair lifting chair rail bar structure-improved, the stair lifting chair by seat, upper rail bar, under Rail bar, several support columns and number pedestal are formed, and the lower end of the seat is equipped with gear, which can be embedded in the tooth of rail bar Row；The two side ends cutting of upper and lower two rail bar is plane, and offers several screw holes, to be fixed on support column；Several branch The lower end of dagger is connected with pedestal, can be fixed on the tread of stair；It is characterized by: rail bar, lower rail bar are real on this Heart metal strip, and the top end face of the lower rail bar directly cuts into tooth row.

When the utility model is used, by the upper and lower rail bar of solid metal item, support column is screwed into screwhole position, then by seat Gear on chair is mutually chimeric with the tooth row of lower rail bar top end face.On rail bar and lower rail bar top end face by solid metal item directly Tooth row is cut, the intensity of rail bar is improved, tooth row is allowed to be not easy to loosen, enables seat and the more firm combination of rail bar, and promotion stair Space, have comparable practicability.

Specific embodiment

It is the stereogram exploded view of the utility model firstly, please referring to shown in Fig. 3.The stair lifting chair 2 by seat 20, on Lower two rail bars 21, several support columns 22 and number pedestal 23 are formed.20 lower end of seat is equipped with 200 (not shown) of gear, It is embedded in the tooth row of lower rail bar；Upper and lower two rail bar 21 is all strip, and is cut in upper rail bar 210 and 211 two side ends of lower rail bar It cuts as plane 2100 and 2110, and suitable distance offers screw hole 2101 and 2111 on a side plane 2100 and 2110, with It is fixed on support column 22；The top end face of the lower rail bar 211 directly cuts into tooth row 2112；The lower end of the support column 22 is pedestal 23。

Secondly, being the perspective view of the utility model please continue to refer to shown in Fig. 4.By the spiral shell of support column 22 and upper rail bar 210 Hole 2101 is screwed, then is screwed with the screw hole 2111 of lower rail bar 211, finally again (does not show the gear 200 of seat 20 in figure Show) it is mutually chimeric with the tooth row 2112 of lower rail bar 211, the assembling of the utility model stair lifting chair can be formed.Utilize solid gold The upper rail bar 210 and lower rail bar 211 for belonging to item can make rail bar 21 more firm.

Then, schematic diagram when being bent please continue to refer to the lower rail bar for shown in Fig. 5, being the utility model.The lower rail bar 211 Directly there is tooth row 2112 in system in top end face cutting, admittedly it can directly be bent, and cutting in two side ends is plane 2110, plane Suitable distance offers screw hole 2111 and fixes with support column on 2110.

Then, please continue to refer to shown in Fig. 6, being the embodiments of the present invention figure.By upper rail bar 210, lower rail bar 211 with Support column 22 screws togather positioning, fits in beside balustrade, by 30 (not shown) of gear of chair lift 3 and lower rail bar 211 Tooth row 2112 it is chimeric, chair lift 3 can be allowed to move up and down.

Finally, being another implementation example figure of the utility model please continue to refer to shown in Fig. 7.By upper rail bar 210, lower rail bar 211 screw togather positioning with support column 22, fit in beside balustrade, cooperate the angle of stair corner, and appropriateness bends upper rail bar 210 And lower rail bar 211,30 (not shown) of gear of chair lift 3 is chimeric with the tooth row 2112 of lower rail bar 211, it can allow lifting Chair 3 is freely turned lifting.

Therefore, the rail bar structure-improved of the stair lifting chair of the utility model, using the unstable solidity of upper avoidable rail bar, By its rail bar is bent, so that chair lift turning moves up and down use, and the space of stair can be promoted, using upper quite convenient.

In conclusion the rail bar structure-improved of the utility model stair lifting chair, can be enhanced the intensity of rail bar, and can subtract Low cost of manufacture.
