Abstract

The crutch type mechanical leg sitting & walking aid is especially suitable for those persons with disabled lower limbs and old and weak persons to walk, go up and down stairs, etc. The extension controllable mechanical leg consists of upper limbs, lower limbs, regulator and control mechanism. The person sitting on a saddle controls the extension or shortening and the walking or locking of the mechanical leg with his hand or foot conveniently and flexibly.

Description

A kind of crutch-type mechanical leg aid

The present invention is a kind of crutch-type mechanical leg aid, is specially adapted to personnel's indoor and outdoor stair activities such as lower limb are wounded or disabled and old, weak, disease, strides ditch and step daily action such as bank, activity such as more be adapted to long-distance walking, go sightseeing.

The present invention is on 91225802.0 and No. 91109308.7 " a kind of apparatus assistant to walking " that I once proposed and No. 94212554.1 " the capable force aid stick of a kind of seat " development basis, newfound a kind of new mechanism that is easy to realize simple in structure that has more.

The object of the present invention is to provide a kind of formula pedipulator seat luggage that turns to put, be characterised in that the outer likeness in form of pedipulator turns, turning body is made up of upper limb and lower limb two parts suit, its mounted inside actuator and operating mechanism, pedipulator and hang saddle and combine, the people is sitting on the saddle and handles pedipulator with hands or foot and arbitrarily control it and elongate or shorten, no matter be walking or stand, the people is sitting in the top and is in features such as resting state all the time, to overcome the deficiency of existing running equipment.

The present invention has two kinds of different enforcements utilization schemes, and the one, the formula sitting aiding to walk appliance is turned in manual control, and the 2nd, the foot control pedipulator is sat line mode, and two kinds of different embodiments face in conjunction with the accompanying drawings are described as follows:

Fig. 1, full crutch-type mechanical leg aid sketch map.

Fig. 2, manual pedipulator structural representation.

Fig. 3, foot control pedipulator structural representation.

Full crutch-type mechanical leg aid shown in Figure 1 is to be constituted by pedipulator and suspension type saddle, wherein pedipulator is by turning handle 1, suspension ring 2, turning body and handle 6 or sole 15 and accessory assembles, it is characterized in that turning body is by upper limb 3, lower limb 8 two parts are formed, upper limb and lower limb mutual sheathing, turn body mounted inside actuator, the upper end and the upper limb of guide rod 9 are combined, match with clutch 10 in its middle part, two clutch arm ends are hinged with lower limb respectively, it is equipped that control stick 11 and lower limb slide, and controls the action of actuator by stick 7 or sole 15, and turning the handle bottom is suspension ring, sitting 5 by suspender belt 4 and saddle combines, constitute a cover crutch-type mechanical leg aid, back-moving

spring

12 or 14 is contained in the lower limb, is useful for manual control or lower limb control respectively.

Figure 2 shows that manual pedipulator structural representation, turn handle 1 and be fixed on the top of upper limb 3, suspension ring 2 are fixed on the bottom of turning handle, the upper end and the upper limb of guide rod 9 are combined, its middle part cooperates with the clutch head, its lower end is passed under the actuator continuation and is extended down to stick below 7, the upper end of control stick 11 an and clutch inclined-plane is slidingly matched, its lower end and stick 7 and handle 6 are combined, the elongation and the shortening of control pedipulator, one end of back-moving spring 12 is connected with the lower end of guide rod 9, and the other end is connected on the fixed point of lower limb 8, and the end that contacts to earth of lower limb is installed contact 13.

Figure 3 shows that foot control pedipulator structural representation, it is characterized in that the lower end of control stick 11 is connected with extension rod 16, lower end and back-moving spring 14 that extension rod passes guide rod 9 combine with sole 15, control the pedipulator operation by sole.

Long-time campaign by present embodiment, fully confirmed purpose of the present invention, the people is sitting on the saddle by hands or foot and controls the pedipulator walking of taking a step, the descending of ascending a height, stride ditch and step bank, freedom of movement promptly is suitable for personnel such as the old,weak,sick and disabled power-assisted of riding instead of walk, more be useful for lower limb permanent disability or single lower limb disabled person and sit capable power-assisted, no matter the people on saddle be to walk or stand if riding seat, human body is in resting state all the time, and this sitting aiding to walk appliance is the laborsaving rugged restriction in ground that is not subjected to again, easy to use, manoeuvrable, freedom of movement, safe and reliable, simple in structure, realize easily.

Claims
