The specific embodiment
With reference to accompanying drawing, shown the collapsible walking aid 10 that the present invention has been specialized, this collapsible walking aid 10 comprises: a central frame 20; Pair of side frames 40 and 60.A body side frame 40 is pivotally connected to the left end of central frame 20, and opposite side framework 60 is pivotally connected to the right-hand member of central frame 20, and forming the U-shaped framework, its intermediate chamber 100 is determined and is used for user and enters into.
This body side frame 40 and 60 operably toward each other the rotation and adjacent one another are, and formation reduces to help the storage configuration of the size that goes on foot frame 10, or pivot rotation is away from each other and in fact perpendicular to central frame 20, and is formed for the utilization structure that supports the user walking or sit down.
This body side frame 40 and 60 is preferably formed by hollow metal pipe.Each body side frame 40,60 has: a pair of preceding and back leg 42,62 and 43,63; Upper beam 44,64; Intermediate transverse girder 45,65; And lower beam 46,66.
Hold part 47,67 and typically made by plastic foam material, this edge is held part 47,67 and is extended along upper beam 44,64, is used for user and supports him or she and oneself walk.
This central frame 20 has isolated upper and lower portion cross frame spares (or crossing frame spare) 22 and 23, and described upper and lower cross frame spare 22 and 23 is fixed or maintenance by a left side and right part tubulose post 24 and 26 with annexation.This end tubulose post 24 and 26 holds the foreleg 42 and 62 of left side frame and right side frame 40 and 60 respectively.Therefore, end tubulose post 24 and 26 plays and allows left side frame 40 and right side frame 60 with respect to the bearing sleeve of central frame 20 pivot rotation between utilization structure and storage configuration or the effect of bearing sleeve.
Because body side frame 40 and 60 is allowed to respectively around bar 24 and 26 rotate freely, in order to improve the rigidity that helps step frame 10, expectation be constrained side framework 40 and 60 degree of pivoting action each other.Telescopic prop 70 is connected between left side frame 40 and the right side frame 60.
This pillar 70 comprises two metal sections 72 and 73, and this pipeline section 73 has less relatively diameter, so that it can slide in pipeline section 72.The flexible of Body of pillar realized by the motion of pipe 73 in pipe 72.Pipeline section 73 may extend into utilization structure and can be retracted back to storage configuration.
Each place, end in each extendable temple members 72,73 is provided with sweep 99.This sweep 99 and sweep 99 and straight portion are changeed each corner part 98 that each pipeline section of just locating can the adjacent sides framework.In the utilization structure that helps the step frame, this has limited body side frame 40 and 60 degree with respect to the pivoting action of central frame 20.
As shown in Figure 5, each pipe 72,73 has stomidium 75 in sweep 99, and this stomidium 75 aligns with hole (not shown) in each entablature 44,64 places setting of each body side frame 40,60.Pivot pin 79 passes every pair of hole, so that pillar 70 is fixedly secured on entablature 44 and 64.
This pipe 73 also is included in the elastic button 74 that is supported by flexural spring 76 in the pipe 73.Pipe 72 and 73 has mating holes 77a and 77b, and button 74 passes this mating holes 77a and 77b is in deployed configuration with holding tube.As shown in Figure 7, when button 74 is pressed, allow pipeline section 72 and 73 relative to each other flexible.
Plastic slide block 92 is fixed in the inside end of pipeline section 73, and this plastic slide block 92 slides to keep conllinear (co-linear) combination between the telescopic section against the inner surface of pipeline section 72.
Seat 80a is preferably made by the softish not seepage material such as nylon fabrics, and this seat 80a removably is suspended between body side frame 40 and 60.
This seat 80a has four holes 82 near its end, and each hole is strengthened by becket.This hole 82 is arranged vertically contiguous its end.In the bottom surface of seat 80a, a pair of hook and circle fastening tape are positioned at each end.
Intermediate transverse girder 45 and 65 upper surface have four thin projections 85 of extending therefrom respectively.This projection 85 for example can be screw or bolt.In case seat 80a flattens on intermediate transverse girder 45 and 65, projection 85 is patchhole 82 then, and the hook strip that is positioned at every side combines with endless belt, so that seat 80a can be fixedly joined to middle transverse rod 45 and 65, so that the user can be sitting on the seat 80a.
In addition, another seat 80b comprises a centre bore 86, so that user can go to toilet, and the seat is placed on the toilet top, is sitting in seat 80b then and goes up with stool or urine as required.
The present invention only utilizes example to provide, and under the situation of the scope of the present invention that illustrates in not deviating from as appended claims, those skilled in the art can carry out multiple modification and correction to described embodiment.For example, replace being provided with the telescopic prop 70 of lock segments, pivotally connected point can be provided with pivot locks between central frame and every body side frame.
