Description
Technical field
This utility model relates to a kind of manpower apparatus of riding instead of walk, is specifically related to the wheelchair that a kind of handrail can horizontally rotate and can conveniently reset.
Background technology
For handicapped old people and people with disability, the wheelchair walking-replacing tool that is absolutely necessary.Along with the development of society and the progress of science and technology, the kind of wheelchair is more and more, and function is also complete all the more, and moulding is also more attractive in appearance.Yet also there is some deficiency in existing wheelchair, especially the handrail of wheelchair is connected by horizontally hinged axle with pedestal, can only rotate up and down around the axis of horizontally hinged axle, can't rotate in horizontal plane, this makes the wheelchair user run into bigger obstacle in daily life; For example from the wheelchair laterally move to other device and go up (move on the public transport seat as by bus the time, or move on the toilet during seat lavatory) and can run into big difficulty, inconvenience is felt more in the action of user.
The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of improvement of wheelchair armrest is provided, this handrail should be able to move to make things convenient for the horizontal of user body around the vertical axis rotation, and has simple in structure and convenience operation.
This utility model is by the following technical solutions:
The wheelchair that a kind of handrail can horizontally rotate, the handrail that comprises seat, is installed in the wheel of seat lower end and is installed in the seat both sides, it is characterized in that: the left side of described seat separates a determining deviation and horizontally disposed guide plate or/and the right side is installed with two respectively, and the rear end of described handrail is inserted in two guide plates also hinged by a jointed shaft and a guide plate of vertically arranging; Described wheelchair also is equipped with the locking structure of a fixed armrest.
Described locking structure is: handrail comprises the handrail parent tube of hollow and the handrail tube that is nested in handrail parent tube outside slidably; The right-hand member of described handrail parent tube is realized the hinged of handrail and guide plate by aforementioned jointed shaft and the hinged back of guide plate; Described handrail parent tube and handrail tube also are connected by a swivel pin parallel with aforementioned jointed shaft, are shaped on the oval hole of matching with swivel pin on the described handrail parent tube, and the long axis in oval hole is parallel with the axis of handrail parent tube; Other has the two ends of an extension spring to collude bundle respectively and applies pulling force in alignment pin and swivel pin; The outside of described guide plate is shaped on the unidirectional draw-in groove that matches with described swivel pin.
The opening of described unidirectional draw-in groove is back to jointed shaft, and the guide plate edge that is positioned at the opening upside is made toward the unfolded involute path of orientation of chair, is beneficial to the chimeric of swivel pin and unidirectional draw-in groove.
Described extension spring is arranged in handrail parent tube inner chamber.
Operation principle of the present utility model is: when wheelchair normally used, spring was strained swivel pin and be embedded in the unidirectional draw-in groove of guide plate, so handrail can keep connecting firmly to guarantee the driving safety of user.When needing to rotate handrail, user only need spur handrail forward makes swivel pin skid off the unidirectional draw-in groove (as shown in Figure 2) of guide plate, can rotate handrail toward the outside (upside shown in Figure 4) to maximum angle then, so that the horizontal of user body moves.When handrail resetted, it rotated counterclockwise (toward seat directions) only to need pushing, embedded unidirectional draw-in groove until of swivel pin " click ", promptly changed normal operating condition over to.
The beneficial effects of the utility model are: turn 90 degrees and can reset easily again because handrail can horizontally rotate to revolve as required, the wheelchair that can only rotate up and down than existing handrail, this utility model is that handicapped old people and people with disability brings great convenience, and easy to operate; In addition, this handrail simple in structure make easily, thereby cost is not high yet.

Fig. 2 is the main TV structure sketch map of the handrail in this utility model.
Fig. 3 is the plan structure sketch map of the handrail in this utility model.
Fig. 4 is the structural representation after the handrail in this utility model horizontally rotates 90 degree.
The specific embodiment
As shown in Figure 1, the wheelchair that this handrail can horizontally rotate, the handrail 30 that comprises seat 10, is installed in the wheel 20 of seat lower end and is installed in the seat both sides, these are the conventional structure of wheelchair.
This utility model in the left side of described seat or the right side be installed with respectively by two and separate a determining deviation and horizontally disposed guide plate 3, also can be installed with simultaneously respectively by two and separate a determining deviation and horizontally disposed guide plate 3 on left side and right side; The rear end of described handrail is inserted in two guide plates, and hinged with guide plate by a jointed shaft of vertically arranging 5; Like this, handrail 30 just can rotate around the axis horizontal of jointed shaft 5.Obviously, the rotation direction of the left side handrail of seat is just in time opposite with the rotation direction of the right armrest of seat.
Described wheelchair also is equipped with the locking structure of a fixed armrest.
As one of embodiment of locking structure, can establish one in addition can movable latch of pegging graft, simultaneously on the guide plate 3 and the pin hole (pin hole axis all coaxial and separate a determining deviation with jointed shaft 5 axis) of making the vertical layout that can match with this latch simultaneously on the handrail 30 respectively; Like this, insert the pin hole of guide plate 3 and handrail 30 simultaneously at latch after, just can guarantee that handrail maintains static.So,, can regulate handrail 30 neatly, it is in rotate or stationary state by latch being extracted or inserted pin hole (pin hole of guide plate 3 and handrail 30).
Further, convenient more for using, locking structure also can be further improved.Specifically as Fig. 2 to embodiment shown in Figure 4 two shown in: as described in handrail comprise the handrail parent tube 6 of a hollow and the handrail tube 1 that is nested in handrail parent tube outside slidably; The right-hand member of described handrail parent tube is hinged with guide plate by aforementioned jointed shaft 5, and then has realized the hinged of handrail and guide plate; Described handrail parent tube also is connected by a swivel pin 2 with handrail tube, and this swivel pin 2 is parallel with aforementioned jointed shaft; For ease of the relative motion between handrail tube and the handrail parent tube, be shaped on the oval hole 7 of matching on the described handrail parent tube with swivel pin, the long axis in oval hole is parallel with the axis of handrail parent tube; Other has the two ends of an extension spring 4 to collude respectively to prick alignment pin and swivel pin; Owing to also be shaped on the stepped projection 6-1 that is used on the roof pressure handrail tube outer circumference surface on the outer circumference surface of handrail parent tube realizing the spacing of handrail tube, so can remain the pulling force that 4 pairs of alignment pins of extension spring and swivel pin apply.
As preferably, described extension spring is installed in the handrail parent tube inner chamber.
The outside of described guide plate is shaped on the unidirectional draw-in groove 3-1 that matches with described swivel pin; The opening of this unidirectional draw-in groove is back to jointed shaft 5, and the guide plate edge 3-2 that is arranged in the opening upside makes toward the orientation of chair involute of (Fig. 4 shows it is counterclockwise), is beneficial to the chimeric of swivel pin and unidirectional draw-in groove.
