Definitions

• This invention relates to a movable manlift formed by a base to which one or more wheels moved by means of motors are connected, a lift mechanism, and a lift platform.
• lifts The most common lift types are vertical lifts, scissor lifts, articulated telescopic lifts, and telescopic lifts. It is common to all these lifts that they are generally controlled by means of a control stick, which is installed either within a cage of a lift platform or on the side of the device for example by means of a remote controller, such that it may be controlled while walking beside it.
• a control stick which is installed either within a cage of a lift platform or on the side of the device for example by means of a remote controller, such that it may be controlled while walking beside it.
• the object of this invention is to provide a manlift which does not involve the problems encountered in the prior art.
• the movable manlift according to the invention is character ized in that control clutches for the wheels of the base of the manlift are integrated to a sur- face of the lift platform, which clutches are operated by moving the weight of the body of a user over the control clutches.
• Preferred embodiments of the manlift according to the invention are characterized by fea tures defined in dependent claims 2-6.
• the movable manlift according to the invention is technically simplest as a version where it is moved along a single axis back and forth.
• the wheels of the motorized base must only revolve in one or the other direction.
• the manlift is installed in such a way that it can be steered and moved for instance along a wall in connection with painting or installation work.
• a technically slightly more complex version is a manlift that moves in all directions. This may be configured for example by using four wheels, the control direction of which is ad justed, and changed about their respective control shafts.
• At a bottom of the device there is a centrally located spring-suspended drive device, driving forward or backward about its drive shaft, the control direction of the drive device being adjustable by rotating the entire device about its shaft.
• control clutches are embedded in a floor of the lift platform, the functions of the clutches being programmable as needed.
• the most significant advantage of this invention is that during construction work, for in stance painting, when the worker is using both hands for work but would like to move the whole standing platform forward, the manlift according to the invention may be moved on the base by moving the user’s weight over the floor of the lift platform.
• the control clutch es are embedded in the floor of the lift platform and are controlled by moving the weight of the user. Thus, the user does not need to step off or empty his or her hands in order to change the position of the lift.

• Fig. 2 illustrates a movable manlift where a lift mechanism has lifted a platform.
• Fig. 3 illustrates a movable manlift platform as seen from the interior and above.
• Fig. 1 illustrates a movable manlift according to the invention, comprising a base 2 to which wheels 4 moved by means of motors 3 are connected, a lift mechanism 5, and a lift platform 6.
• Control clutches 8 for the wheels 4 of the base 2 of the manlift 1 are integrated to a surface 7 of the lift platform 6, which clutches are operated by moving the weight of the body of a user 9 over these control clutches 8.
• the control clutches 8 are programmable by the user 9 as needed. Power transmission is provided via at least one wheel.
• Fig. 2 illustrates the movable manlift 1 according to the invention, where the lift mecha- nism 5 is lifting up the lift platform 6.
• Fig. 3 shows the platform of the movable manlift according to the invention as seen from the interior and above.
• the control direction of four wheels 11 of the lift is adjusted, and changed about their respective control shafts 12.
• At a bottom 13 of the device there is a centrally located spring-suspended drive device 14, driving forward or backward about its drive shaft 15, the control direction of the drive device being adjustable by means of a mo tor 16 by rotating the entire drive device 14 about a vertical shaft 17.
• the manlift according to the invention may naturally be provided with guard rails, alt- hough that is not illustrated in the figures.
• the number of the wheels 4 is not limited to four, but it may be any- thing from one upwards.
• the wheels may also be spherical and freely swiveling, such that they may move in all directions in a horizontal plane.
• the manlift according to the inven tion may of course also move on a chain track.
• the lift mechanism is a vertical lift, scissor lift, articulated telescopic lift, or telescopic lift.
