Description
ACTUATING DEVICE
FILED OF THE INVENTION
The present invention relates to an apparatus which is cooperated with other braking mechanisms for stopping the movement of an object. For example, the present invention can be installed with handles of a walker with wheels to control the movement of the walker.
BACKGROUND
A walker with wheels (i.e. rollator, or rolling walker) becomes more and more popular. For example, U.S. Pat. No. 4,907,794 and 5,020,560 disclosed a foldable rolling walker. Consequently, a braking system is needed to stop the wheels. However, such braking system is a temporally braking device which is similar to that of a bicycle, i.e. a braking effect is actuated only when a user pulls up the braking handle.
U.S. Pat. No. 5,279,180 (Henriksson) disclosed a braking system which can be operated in two manners, i.e. temporally and continuously braking status.
When a user push a operative arm of downward, by utilizing the "locking force"
to maintain the operative arm in a continuously locking position. Therefore, when the user releases the operative arm, for example, the wheels of a rolling walker are still braked. However, the "locking force" must be larger than the returning force of the releasing spring installed in the braking system, which may causes following defects:
1. The locking engagement between a operative arm and a bracket is affected by an interference fit therebetween, as a result, after a period of usage, the contacting area will be worn out and the "locking force" will be decayed.

When a user push a operative arm of downward, by utilizing the "locking force"
to maintain the operative arm in a continuously locking position. Therefore, when the user releases the operative arm, for example, the wheels of a rolling walker are still braked. However, the "locking force" must be larger than the returning force of the releasing spring installed in the braking system, which may causes following defects:
1. The locking engagement between a operative arm and a bracket is affected by an interference fit therebetween, as a result, after a period of usage, the contacting area will be worn out and the "locking force" will be decayed.
2. Because the ''locking force" is larger than the returning force of the releasing spring, the force of pushing operative arm of downward, therefore, much larger than the returning force of the releasing spring. The pushing force will speed up ruining the contacting area of the operative arm and the bracket.
SU1~ARY OF THE INVENTION
It is an objective of this invention is to solve the defects of above prior art.
Another objective of this invention to simplify the mechanisms of a actuating device. According to the third embodiment, a simplest mechanism is disclosed.
The present invention comprises a bracket and a operating device. The bracket comprises a mounting device and a receiving chamber. The actuating device can be mounted to another device, such as a rolling walker, to actuate the braking function for wheels. The front end portion of the operating device can be received within the receiving chamber.
According to one aspect of the present invention, the operating device can be operated at three different positions corresponding to the bracket. When the operating device is located on the second position, the braking function is not effected. When the operating device is moved upward by an external force (e. g. user's hand), a temporally braking function is attained and when the external force is removed, the operating device will quickly return to the second position to stop the braking function. When the operating device is moved downward, the operating device can be continuously locked thereof to prolong the braking function. The above function can be achieved by the design of the first operating portion of the operating device.
In summary of this invention seeks to provide an apparatus for actuating a brake device of a wheeled object comprising: a bracket comprising a mounting device for mounting said apparatus to the wheeled object and a receiving chamber for receiving an operating device; the operating device having a front end portion, the operating device being pivotally installed in said receiving chamber for manually operating said apparatus, wherein the front end portion of said operating device being provided with an anchoring portion and a first operating portion which is defined by a first, a second and a third edge, and wherein said front end portion of said operating device further comprises a second operating portion which is a closed hole, said bracket being further provided with a second post which passes through said receiving chamber of said bracket and said second operating portion of said operating device; a first post being fixedly mounted and passed through said receiving chamber of said bracket such that said first post is contacted with said first operating portion of said operating device, said first post being disposed in a position above said anchoring portion of said operating device;
wherein said front end portion of said operating device being disposed within said receiving chamber of said bracket such that said operating device can be selectively located at a first, a second or a third position, wherein when said operating device is located at said first or second position, said first post is located between said first and second edges of said first operating portion of said operating device, and wherein when said operating device is located at said third position, said first post is disposed at said third edge of said operating device; wherein when said operating device is located at said second position, a braking function is not effected, wherein when said operating device is moved to said first position by and upward external force, the braking function is effected temporarily and when said upward external force is removed, the braking function is ineffective, and wherein when said operating device is moved to said third position by a downward external force, the braking function is 2a effected continuously and when said downward external force is released, the braking function is effected continuously.

Detailed Description of Preferred Embodiment Referring to Figure l, a walker 70 is shown and which is installed with a actuating device 10 to brake the wheels 73 through braking cables 72.
Referring to Figures 2 to 4, the actuating device 10 mainly comprises a bracket 20 and a operating device 30. In this first embodiment, the bracket 20 defines a mounting device 21 and a receiving chamber 22. The actuating device 10 can be readily installed to a handlebar 71 of walker with the mounting device 21 of the bracket 20. The receiving chamber 22 is provided with an opening 23 with which the front end portion 31 of the operating device 30 can be pivotally installed therein.
The front end portion 31 of the operating device 30 is provided with an anchoring portion 32 for fixing the anchoring head of the braking cable 72 thereof. The other end of the braking cable 72 is connecting to the braking mechanisms disposed adjacent to the wheels 73 of the walker 70. Detail -, _,_ description is not provided herein since it is well known to the skilled in the art.
The bracket 20 is provided with a first, second and third mounting holes 24, 25 and 26 in which a first, second and third posts 41, 42 and 43 having threaded recess at the free'end can be fixedly retained thereof by means of locking screws 44. The front end portion 31 of the operating device 30 is provided with a first, second and third operating portions 33, 34 and 35 corresponding to the first, second and third posts 24, 25 and 26 respectively. The first operating portion defines the first, second and third edges 331, 332 and 333.
Normally, the operating device 30 is on the second position 52 when the braking mechanism is not actuated. When the operating device 30 is pulled upward to the first position 51, a temporary braking is actuated. After the external force (e.g. force from user's fingers) applied to the operating device 30 is released, the operating device 30 is returned to the second position 52 by the returning force of the braking cable 72. When the operating device 30 is located at the first and second positions 51 and 52, the first post 41 is positioned between the first and second edges 331 and 332 of the first operating portion 33.
When the operating device 30 is pushed downward, the operating device 30 moves to the third position 53 such that a continuous braking is effected.
In this situation, the first post 41 is located at the third edge 333 of the first operating portion 33. An intersecting angle 334 is defined between the second edge 332 and the third edge 333. Preferably, angle 334 is less than 120 degrees such that the returning force of the braking cable 72 can be overcome.
Furthermore, because the first post 41 is disposed above the anchoring portion 32, the braking cable 72 can provide a counterclockwise torque to the first post 41, and therefore even the external force applied to the operating device is removed, the operating device 30 will be maintained in this the position 53 by the torque applied from the braking cable-72. As a result, a continuous braking status is achieved.
From the forgoing description, the main function of the first operating portion 33 is to provide a locking force to the operating device 30 which is on the third position 53. The second operating portion 34 has a triangular shape in this embodiment and it is used to prevent the operating device 30 from escaping when the braking cable 72 is broken. Therefore, the second operating portion 34 is designed as a closed hole. The second operating portion 34 shall be specially designed such that the operating device 30 will not be limited by the second post 42 when the operating device 30 is moved upward or downward. Consequently, the second operating portion 34 should be designed as a hole with proper size.
The main function of the third operating portion 35 is to provide a ending point when the operating device 30 is pushed downward by a user. As a result, a better operation feeling can be provided while the user is pushing the operating device 30 downward. In fact, the third operating portion 35 can be omitted or be replaced by the modified shape (not shown) of the lower portion 311 of the front end portion 31. The lower portion 311 can also be served as an ending point cooperated with the contacting area of bracket 20. In the second and third embodiments, the third operating portion 35 is omitted (referring to Figures 5 and 6). Because the braking functions of the second embodiment are the same as those of the first embodiment except the lack of better operation feeling, therefore no detail description is given herein.
As described above, the main function of the second operating portion 34 is to prevent the operating device 30 from falling off thereof when the braking cable 72 is broken. However, such situation seldom happens, and therefore the second operating portion 34 can be also omitted. As shown in Figure 7, the second operating portion 34 is omitted in the third embodiment. Although the configuration is simplified, the braking effect is identical to the first embodiment, consequently, no detailed description is given.
Figures 8 to 10 are the schematic illustrations of the consecutive movements of the fourth embodiment. The difference of the fourth embodiment from the first embodiment is the second operating portion 34' is provided with a projected portion 341'. As a result, the projecting portion 341' can help (just a little) the operating device 30 kept on the third position 53. Because the working principle and braking operation are also identical to the first embodiment, no detail description is given.
The invention in its broader aspects is not limited to the specific details shown and described, and departures may be made from such details without departing from the principles of the invention and without sacrificing its chief advantages. For example, the first operating portion can be a closed hole or the number of the edges the first operating portion is more than three.

Detailed Description of Preferred Embodiment Referring to Figure l, a walker 70 is shown and which is installed with a actuating device 10 to brake the wheels 73 through braking cables 72.
Referring to Figures 2 to 4, the actuating device 10 mainly comprises a bracket 20 and a operating device 30. In this first embodiment, the bracket 20 defines a mounting device 21 and a receiving chamber 22. The actuating device 10 can be readily installed to a handlebar 71 of walker with the mounting device 21 of the bracket 20. The receiving chamber 22 is provided with an opening 23 with which the front end portion 31 of the operating device 30 can be pivotally installed therein.
The front end portion 31 of the operating device 30 is provided with an anchoring portion 32 for fixing the anchoring head of the braking cable 72 thereof. The other end of the braking cable 72 is connecting to the braking mechanisms disposed adjacent to the wheels 73 of the walker 70. Detail -, _,_ description is not provided herein since it is well known to the skilled in the art.
The bracket 20 is provided with a first, second and third mounting holes 24, 25 and 26 in which a first, second and third posts 41, 42 and 43 having threaded recess at the free'end can be fixedly retained thereof by means of locking screws 44. The front end portion 31 of the operating device 30 is provided with a first, second and third operating portions 33, 34 and 35 corresponding to the first, second and third posts 24, 25 and 26 respectively. The first operating portion defines the first, second and third edges 331, 332 and 333.
Normally, the operating device 30 is on the second position 52 when the braking mechanism is not actuated. When the operating device 30 is pulled upward to the first position 51, a temporary braking is actuated. After the external force (e.g. force from user's fingers) applied to the operating device 30 is released, the operating device 30 is returned to the second position 52 by the returning force of the braking cable 72. When the operating device 30 is located at the first and second positions 51 and 52, the first post 41 is positioned between the first and second edges 331 and 332 of the first operating portion 33.
When the operating device 30 is pushed downward, the operating device 30 moves to the third position 53 such that a continuous braking is effected.
In this situation, the first post 41 is located at the third edge 333 of the first operating portion 33. An intersecting angle 334 is defined between the second edge 332 and the third edge 333. Preferably, angle 334 is less than 120 degrees such that the returning force of the braking cable 72 can be overcome.
Furthermore, because the first post 41 is disposed above the anchoring portion 32, the braking cable 72 can provide a counterclockwise torque to the first post 41, and therefore even the external force applied to the operating device is removed, the operating device 30 will be maintained in this the position 53 by the torque applied from the braking cable-72. As a result, a continuous braking status is achieved.
From the forgoing description, the main function of the first operating portion 33 is to provide a locking force to the operating device 30 which is on the third position 53. The second operating portion 34 has a triangular shape in this embodiment and it is used to prevent the operating device 30 from escaping when the braking cable 72 is broken. Therefore, the second operating portion 34 is designed as a closed hole. The second operating portion 34 shall be specially designed such that the operating device 30 will not be limited by the second post 42 when the operating device 30 is moved upward or downward. Consequently, the second operating portion 34 should be designed as a hole with proper size.
The main function of the third operating portion 35 is to provide a ending point when the operating device 30 is pushed downward by a user. As a result, a better operation feeling can be provided while the user is pushing the operating device 30 downward. In fact, the third operating portion 35 can be omitted or be replaced by the modified shape (not shown) of the lower portion 311 of the front end portion 31. The lower portion 311 can also be served as an ending point cooperated with the contacting area of bracket 20. In the second and third embodiments, the third operating portion 35 is omitted (referring to Figures 5 and 6). Because the braking functions of the second embodiment are the same as those of the first embodiment except the lack of better operation feeling, therefore no detail description is given herein.
As described above, the main function of the second operating portion 34 is to prevent the operating device 30 from falling off thereof when the braking cable 72 is broken. However, such situation seldom happens, and therefore the second operating portion 34 can be also omitted. As shown in Figure 7, the second operating portion 34 is omitted in the third embodiment. Although the configuration is simplified, the braking effect is identical to the first embodiment, consequently, no detailed description is given.
Figures 8 to 10 are the schematic illustrations of the consecutive movements of the fourth embodiment. The difference of the fourth embodiment from the first embodiment is the second operating portion 34' is provided with a projected portion 341'. As a result, the projecting portion 341' can help (just a little) the operating device 30 kept on the third position 53. Because the working principle and braking operation are also identical to the first embodiment, no detail description is given.
The invention in its broader aspects is not limited to the specific details shown and described, and departures may be made from such details without departing from the principles of the invention and without sacrificing its chief advantages. For example, the first operating portion can be a closed hole or the number of the edges the first operating portion is more than three.
