Definitions

• the present invention relates to an apparatus for imparting a movement to and actuating an object and comprises a bracket with an operating device, preferably in the form of a handle, stirrup, arm or lever and which is disposed in connection with the object via connection devices.
• the object may, for example, consist of a brake for a wheel on a vehicle, implement or other wheeled apparatus.
• Such an actuating apparatus or regulator may be employed within a multiplicity of different fields, for example, for triggering or operating an apparatus, an object such as the exemplified brake, a contactor or for tightening a line or other elongate object. On occasions, such apparatuses are provided for being able to actuate an object or the like to assume two different operative positions.
• the brake regulator In, for example, a handbrake, the brake regulator must be pulled on during the entire time when braking effect is to be maintained. Such a design of a brake or an operating device therefor is sufficient in many cases. In other cases, it would be an advantage if a braking effect could be maintained without the need for a brake regulator to be operated during the time when it is desired to maintain the braking effect. This is particularly desirable in such brakes in which, where applicable, braking effect is to be maintained during a relatively long period of time and are moreover mounted in, for example, vehicles or implements which are to be used by people suffering from partial handicap or with reduced strength, in particular in the hands. Rolling walkers or walking frames are examples of such equipment which, moreover, are employed by people suffering from some form of movement handicap.
• the user of a rolling walker often needs to brake the rolling walker while walking, which is effected using an instantaneously operating brake.
• a parking brake position i.e. that the braking effect is maintained without the user needing to handle the apparatus, its operating device or a brake regulator during that time when the braking position is to be maintained.
• Such a parking brake position can also be utilized while walking, when braking needs to be effected during a relatively lengthy time, for example when negotiating a descent.
• that hand movement which must be executed is relatively long for achieving the necessary stroke length for satisfactory application of the brake. Furthermore, an unnecessarily large force is also required for achieving a satisfactory braking effect.
• the set requirements are satisfied at the same time as the drawbacks inherent in prior art apparatuses are obviated.
• the apparatus is easy to operate, requires less movement capability and force on the part of the person operating the apparatus for achieving the intended effect and handling of the apparatus for actuating the object or the brake can be effected employing only non-precision motoricity.
• the apparatus is further designed to be able to assume at least one position in which the apparatus actuates the object to assume an operative position, and retains the object during that time in the operative position. In the said position of the apparatus, the apparatus will remain in a stable position, the rest position, or in an assumed locked position, i.e.
• the apparatus remains in that position until such time as a new operation, actuation or command is made.
• the apparatus is designed in such a manner that a smaller or shorter operative movement need be carried out for achieving the necessary stroke length for imparting the movement or actuation to the object which is to be actuated.
• the apparatus can be designed with simple means to be adaptable according to those individual user's needs, which thus entails an individual adaptation or increased adaptation in individual cases.
• the apparatus moreover displays such a design that it can be manufactured in a simple manner and be correctly dimensioned, which achieves improved dependability as regards function and against wear and tear.
• An apparatus is, in this instance, characterized in that the connecting device includes an element which is rotatably disposed in the bracket about a first pivot, shaft or the like and which displays a connecting portion for a coupling device which is disposed in spaced apart relationship from the above-mentioned first pivot, and that the operating device is disposed in the apparatus in said element.
• the operating device is disposed in the above-mentioned element between the first pivot and the connecting portion.
• the operating device is rotatably disposed in the above-mentioned element in a second pivot, shaft or the like and displays at least one first and one second abutment.
• the bracket displays a first abutment surface for the operating device, which abutment surface displays a defining edge against a second abutment surface for the operating device.
• the second pivot or shaft is anchored in the above-mentioned element and, together with .the element, is disposed rotatably about the above-mentioned first pivot, and the operating device is rotatably disposed either-'about the first pivot or shaft and, in such instance, together with the element for assuming a second position, or about the second pivot or shaft for assuming a third position.
• the apparatus is intended to be disposed in a first position or a rest position in which the object is intended to be in a first position and disposed, on handling or actuation, to be capable of assuming or being moved to a second position in which the object is brought to a second position or operative position, and further disposed, on handling or actuation, to be capable of assuming or being moved to a third position in which the object is also brought to the above- mentioned second position or operative position, in which, on assumption of the said second position, the operating device and said element are disposed to rotate about said first pivot and, on assuming said third position, the operating device is disposed to rotate about said second pivot, said element and said second pivot being disposed to rotate about said first pivot.
• the above-mentioned abutment surfaces and defining edge of the bracket are disposed on a body which is arranged to be disposable in the bracket and thereby is arranged to be replaceable by one or more other corresponding bodies with abutment surface, abutment surfaces and/or defining edge, of a different extent, angle, positioning or the like and/or a different dimension.
