The installation position is mostly at the front end of the armrest, but each user's body shape and elbow length are different. Only moderate adjustments can be performed in the best position, and under different conditions of use, adjustments must be made to different positions in order to give full play to the functions of a wheelchair. Examples include eating or working close to the edge of a table, washing in front of a washbasin, and passing through a narrow aisle. [Previous technology] The conventional or general controller is installed at the front of the armrest in a fixed position and cannot be moved, or it is installed in front of the armrest by a parallel four-link mechanism. Although it can be rotated, it can only be at the starting point of the turning radius. Two fixed stops. To stay or turn, you need to lock the four-link mechanism with a buckle or a movable latch. The use range is greatly restricted and the operation is not convenient. For patients with cerebral palsy or atrophy of the hand, it may even Generated inoperable. Some users succumb to the existing poorly designed products for a long time, reluctantly operate, causing discomfort, and even severely deforming the body position, which is painful and troublesome. Moreover, when using the four-link mechanism, accidentally putting their fingers And clothes, etc., causing accidental injury. How to improve the above shortcomings is the main demand of this creation. [New content] 1. The technical problem to be solved: The main purpose of this creation is to provide a supporting activity structure of the controller of the electric wheelchair, which can be reduced, up, down, left and right, and can be used to position M262167 in any position. Positioners, this device must be a simple structure, strong, easy to operate, the queen will not cause accidental damage to the user, and has a beautiful appearance and multiple purposes. So far, no structure or technical literature has been published in this area. . Second, the technical means to solve the problem ... In order to solve the aforementioned problems, the main structure of this creation is as described in the first scope of the patent application:-two-piece clamping block located under the wheelchair armrest ~ for the gyrator device and A pair of sprocket wheels linked to the clamping block are installed at the two ends of the interior of the metal case of the gyrator, and two sprocket wheels are connected by a chain (or a timing belt and a timing belt pulley, both of which can be driven synchronously) The shaft passes through the bearing holes of the sprocket and the gyrator housing respectively, and a proper length of a wheelchair controller's fixed seat is welded to the shaft end of one of the above planetary shafts. Brake handle ~ Gyroscope base 2. Contrast with the effect of the previous technology: With the implementation of this creation, the following advantages can be obtained: 1. The cool holding block of this design is used to combine the armrest with the gyroscope. This product can be installed if the armrest of the same brand is the same size. At the same time, the clamping block can be adjusted forward and backward to match different elbow lengths. 7 M262167 2 · The purpose of the wheelchair control mounted on the return% el is in the same direction as the rotation. If there is a special need, it can be adjusted to the homeostatic direction of the operator without modification (such as Hand deformities need to skew the operator). 3. This device can be installed at any position during the turning movement. The brake can be controlled by the brake handle or the meal can be set. 4. The previous technology of the four-link mechanism, if the user will push the controller to the armrest touch 1 when approaching the edge of the table, when the hand _ paste test section, because there must be a thick power cord behind the device, there will be A considerable amount of elasticity causes a rebound, causing considerable inconvenience. However, since the sprocket and the chain have a certain damping coefficient, the elasticity of the power cord will be offset by a moderate counterbalance during the rotation of the design. After the operator let go, there will be no rebound phenomenon, so you can do whatever you want. Place it where you want it. 5. The brake lever of this creation is located at the back of the wheelchair controller. It is in line with human body operation and can be used freely during the whole turning process. [Embodiment] The following detailed description is based on the embodiment shown in the figure: (First implementation type) As shown in the first figure, the creative gyrator 1 is installed in the front 2 of the wheelchair armrest 2 and the controller 3 The exterior view of the room; and Figure 67 shows the diagram and side view of the creative mechanism; the gyrator reveals: This design is divided into a main body and an outer cover by a metal shell, which is covered with two sprocket wheels, two The sprocket on the outside of the sprocket is surrounded by a chain C with a calculated length, so that the M262167 wheelbase of the two sprocket and the bearing of the casing are sulfur _, and the sprocket A _ Aa passes through the front and rear ends of the core hole Expose the set length, lock it with a lion lock to penetrate the bearing hole, the long shaft end of the car is known with a -screw hole, and a ―half-moon-shaped plane‖ is drilled to combine with the controller fixing seat , The plane at the end of this axis is consistent with the final set next to _ 孔 on @ 定 座. When assembled, it is used to ensure that the shaft and the mount will not cause rotation. In addition-the sprocket B is passed through the central hole by the shaft Bb, and the set length is also exposed at the front and back ends, and it is locked with a set screw in order to penetrate the bearing hole. The _ hole wire is drilled inside and is connected to the ―end of the connecting rod 4 and the other end is clamped by the iron pipe fixing block 5 covered under the armrest, so that the iron pipe c through the armrest extends to the connection through the fixing block 5 The lock lever 4 is up to the axis of the sprocket, and the entire casing is firmly supported on the armrest ', and the Bb axis can be used as the center. In __ making towel, through Lai's material, always maintain the fixed orientation of χ pumping, that is, the control on the A_ axis of spinning _ making towel is all running in one direction. It has a complete phase function with the four-link mechanism, and has a large rotation angle than the traditional ones, which can be proved by the figure nine. In the sixth figure, 7 is a brake. The brake lever is 7a, and it is at the top of the shaft center of the% brake. This axis passes through an eccentric circular shaft 7c. The small circular hole on the eccentric circular shaft with the elastic pin 7d and the brake The small circular hole on the shaft 7b penetrates both to fix it. The above three parts pass through the _shaft holes and 11 on the main casing 8 and the cover 9 and place a liner on the door of __ 7e There are two protruding positioning pieces on the 7e sword car piece. The eccentric circular drawing 7c restricts the radial rotation. When the operator rotates the crane handle to the angle, M262167 is driven to rotate due to the eccentric circular shaft 7c, which causes the squeeze chain to be pushed into the main casing. The squeeze force generated by the butterfly plate causes point and surface enlargement. Side, so that the chain cannot be moved in this space ', that is, A miscellaneous and B miscellaneous cores cannot be turned. The entire ship is locked and rotated, and it is also braked. When the operator rotates the brake lever 7a in the reverse direction to release the brake, the gyrator can freely rotate again.
