Description of the invention (1) The present invention relates to a brake system according to the preamble of the first patent application park attached to the attached patent application. This type of wheeled walking frame is usually constructed of a gold tube, which gives it a smooth, durable and quite lightweight structure. According to the laws of most European countries, this type of wheeled walker must meet certain requirements in order to be used in public health. The outside of the wheeled walker should heal better, that is, it should be clean, have a smooth surface, have almost no dusty recesses, and have almost no protruding elements. The wheeled walker system is further provided with a brake on each handlebar. The handlebar system must be interactively adjustable in the vertical direction in the simplest manner possible, and the adjustment of the brake is relatively easy. The best place should either be produced at the same time or be implemented in a very simple way. Briefly explain the structure of the conventional technology, in which the braking force transmitted from the handlebar to the brake is roughly achieved through three structures, which are respectively a flexible cable, (b)-a belt or a braid Tightening ropes, or (c)-Metal rods, all constructions are fully or partially located outside the metal tube. These conventional brake systems often have disadvantages. The flexible cable is loop-shaped and may hook onto protruding items, such as furniture handles. Similarly, the woven belt system can only be adjusted after the handle is moved, and the metal rod system provided on the outside of the pipe body may hook to foreign objects. All three types have a common feature, that is, they are not noticeable and difficult to maintain cleanliness, and meditation is the most important. Since the wheeled walker system is loaned to different patients to use during their rehabilitation, So the wheeled walker must be kept clean before passing it on to the next user. 4 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) ------------, (-< — (Please read the notes on the back before filling this page )-** Printed by the Consumer Property Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by Shellfish Consumer Cooperatives 436284 A7 B7 V.

Description of the invention (Hand-held element into a handlebar 12 'and around a shaft 15 and The pivoting brake lever is shown in three different positions in the figure, which are a brake position 13, a neutral position 13a, and a latching position 13b. The brake control lever has a pressing surface 14 ′ for contacting the biasing spring pressing plate 16, and the spring biasing plate 16 is provided on the upper end of the lever member 17 a, and the lever member 17 a constitutes an extendable brake lever. One of the parts of the part π "and the other part are a tube body 17b in which the rod member 17a moves, and a brake device 18 in the form of a threaded bolt is screwed into the lower end of the tube body 17b. The latch abuts on a walking wheel 19 (only a part of which is shown in the figure). Since it should be suitable for both tall and short people to use this wheeled walker, the handlebar system must be able to be raised or lowered, and after adjustment, the system can be fixed in this adjustment position. For this purpose, a threaded hole 110 is provided in the upper end region of the outer frame frame tube 10. For example, a set of tube nuts is provided with a screw 111 attached with a finger grip wheel, which can be turned to Rotate inside and out. Internally, the two retractable frame and frame pipes are locked to each other, because the screw system has penetrated into one of the holes 112, and the holes are punched out in stages on the inner frame and frame pipe 11. A similar locking arrangement of the sleeve nut 113 and the screw 114 is mounted on the pipe body 17b. When the screw 114 is screwed in, the lever member 17a is quickly clamped against the pipe body 17b. The screw is passed through an oval hole 115 punched out of the outer frame frame pipe 10. The length of the hole 115 is slightly longer than the diameter of the screw 114. This is for the brake lever 17 to be pressed down in the locked position. So far, the brake device 18 has been pressed against the walking wheel 19 to produce a braking effect. . When the handlebar changes its vertical position, the procedure is as follows.

Raise or lower the handle until one of the appropriate holes 112 on the frame pipe 1 is aligned with the screw 111, and then screw the screw 111 into the hole 112, so that the frame pipe can be fixed to each other 4 and then screwed in. The screw 114, as a result, the rod member 17a can be locked against the tube body 17b. Printed by the Shellfish Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Figures 2a, b, and c illustrate different variations of the present invention with slight changes. Here, retractable frame and frame pipes are marked with 10 and 21. In the vertical position of these elements, they are fixed to each other in the same manner as for the embodiment illustrated in FIG. 1, in other words, a screw 211 is moved in a sleeve nut 210. The screw 211 is provided with a short shaft 216 which passes through a hole 212 in the inner frame frame pipe 21 and is in a vertically fixed state. The brake lever member 217 in this implementation is composed of two lever members 217a and 217b having a block shape. The lever members are axially displaced from each other and are locked at a predetermined distance, and are locked on a latch 214 provided by the lever member 217a (the lever member on the left in Fig. 2a). In the rod member 217b on the right side, the rod member 217b is provided with slots 215 at equal intervals and has the same interval as the hole 212 in the inner frame frame pipe 21. Cooperating with the function of the screw 211, the short shaft 216 is pressed against the rod 217a. In this example, the rod 217a is pressed against the rod 217b, and the latch 214 is fitted in the slot 215. The rod is therefore fixed in the axial direction. The β-U-shaped bending plate 213 is used to ensure the lateral positioning of the rod. The locking mechanism of the adjustable element occurs simultaneously with the function of the screw 211.

Description of the invention (I) A finger grip wheel, a short shaft 216, and a latch 214. The procedure for adjusting the vertical position of the handlebar is quite simple. The screw 211 is withdrawn as far as possible as shown in Fig. 2b, i.e. it is completely disengaged from the exit hole 212. Then, under the action of the spring 218, the latch 214 has released the engagement state between the latch and the slot 215, and the rods 217a and 217b are axially displaceable relative to each other. Therefore, the height of the handle can be determined by screwing in the screw 211, and when the pin 214 is inserted into the slot 215 and engaged with the slot, the frame pipe is locked at the same time. The length and design of the short shaft 216 are such that a certain degree of radial movement exists between the brake lever member and the frame frame tube. This is to allow the brake lever member to move without generating excessive friction. Moreover, it does not endanger its own braking function. After all, the braking action has been set in advance by a relatively small vertical movement. In the two illustrated embodiments, the vertical position of the handlebar is limited to a predetermined number. In the embodiment described below with reference to FIGS. 3a and 3b, this adjustment is a stepless adjustment. The inner frame frame pipe 31 is provided with a longitudinal slot 312, which is slightly longer than the total length adjusted vertically. In the outer frame pipe 30, a hole 315 has a diameter equal to the width of a slot 312. The lock of the two frame-frame tubes is generated by a nut 318 arranged in the inner frame-frame tube and a head disposed between the heads of the screws 311, and the circumferential portion 320 of the head is formed. It is jagged and constitutes a grip for a finger grip or a ball knob 319, wherein the finger grip or the ball knob rotates around a shaft 316 which is pivotally received in a hole of a screw 311. The free end design of the shaft 316 is the same as the ~ H-shaped drill. 11 This paper size applies to the Chinese National Standard (CNS) A4 (210 X 297 mm). ^ .1 n Γ nnn «I n.

Description of the invention (1) The head 'It is enough Help the brake screw 32 rotate in the tube body 317b provided with a threaded brake lever member 317. As mentioned above, in terms of weight, it is formed as thin as possible, and a socket 322 surrounds the tube It is provided at the end of the body and most of this socket is provided with threads. In this embodiment, the buckle of the adjustable element occurs synchronously with the action of the screw 311, the shaft 316, and the brake screw 321. The action is as follows. According to _ 3a, it starts from the position of the buckle, where the brake screw 321 is retracted first to release the element of the brake lever. After that, the knob 319 is pulled out until it reaches the knob 319 Reach with screws 31 The tooth portion 320 of 1 is combined. Then, the screw is released and clamped, and then the handle can be positioned in the required vertical position. The buckle is simply implemented in the reverse order. First, the frame pipes are clamped to each other, the spherical handle 319 is forced, and the brake screw is tightened, so that the components of the brake lever can be locked in the axial direction. The invention is implemented in the above description. The example is provided with a compression brake lever member, which is not limited in the present invention. The brake lever member can also be operated by the action of pulling. The above-mentioned changes are explained in Figs. 4a-4c. In the example of the brake lever in the illustrated example, there must be a compression effect on the brake lever member, but in this embodiment, it can be replaced by the action in the drawing direction. Therefore, the brake lever 43 (as shown in FIG. 4a) presses a pressing surface 46 provided on its pivot shaft 45 against the ear 49, wherein the ear is connected to a rail 47a 'the rail is sequentially Connect the same similar rail 47b — shape Brake lever 47 ° 12 This paper size applies to Chinese National Standard (CNS) A4 (210 X 297 mm) -I ί—fllllllll-II {Please read the note on the back before filling this page) Order:- -Line.

Description of the invention (/ e) The rails move between each other 'Also, they can be latched with each other in the recess 415 of the other rail 47a via a latch 416 provided in the rail 47b, and can be locked with each other in the axial direction. This combination occurs when the rails are pressed axially against each other. The mechanism of this locking operation is similar to the mechanism described in FIG. 2. The screw 411 is provided with a spherical handle 'which can be rotated and fixedly welded to the outer frame pipe 40 within the thread of a sleeve nut 410. In general, in the middle of the withdrawal process, the screw is disconnected from the inner frame frame tube 41 connected to the screw. The rail of the brake lever member is then kept separated by the action of a thin leaf spring 418. Therefore, the handlebar 412 can be raised or lowered to a desired level at this time. When the screw 411 is aligned with the hole in the inner frame frame pipe, the screw is screwed in so that the pin 416 is fitted with the hole 415. The length of the screw is designed so that there will be no "clamping" in the radial direction, but when the screw is fully tightened, it will produce a certain action. Therefore, the brake lever is not obstructed by friction when it moves, whether it is between the screw and the rail or between the rail and the inner frame frame tube during braking. Since the braking operation is generated by a drawing action, the concept of the braking device 420 is different from the previously explained. The traction force is transmitted from the brake lever through a traction link 422 and a rocker arm 421, and the compressive force affects the brake device. The advantage of a movable brake lever member is that it allows weight in its dimensions to be lighter than that of a compressed movable brake lever member, so there is no risk of the movable brake lever member being bent outwardly. Therefore, it is expected that the rails 47a and 47b can be made of plastic. 13, ί ml ——— — — — — It I (please read the No. Emperor item on the back and fill in this page first) Order · 丨 The size of this paper applies the Chinese National Standard (CNS) A4 (210 X 297) %)
