Safe tender lift

Abstract

The invention comprises of a tenderlift ( 1 ) for watercraft with a high safety standard, such as the safe picking up of the tender ( 7 ) by means of guide sticks ( 9 a, b ), curved elements ( 9 c ), deadrise elements ( 10 ), tender locking ( 11 ) as well as for an easier positioning of the tender on the platform ( 8 ) with an integrated revolving plate ( 12 ) which) can be accordingly turned by coercion adjustment or by means of an operating cylinder ( 19 ). In addition the swivel arms ( 3 a , b) are concealed, so that no gap ( 3 c ) can occur and no bruising of limbs or other means can occur. When the tenderlift ( 1 ) goes down, the integrated ladder ( 25 ), lying under the platform ( 8 ), automatically extends with the stroke (H), which has release elements ( 28 ) on the pivot bearing ( 27 )

1 . Tenderlift for watercrafts characterized in that the tenderlift has a platform, which positions and holds a tender in position by means of deadrise elements, guide sticks, curved element, tender locking or/and has a revolving plate or/and interlocking swivel arms with at least a U profile or/and a connecting ladder. 
     
     
         2 . Tenderlift according to  claim 1  characterized in that the guide sticks, deadrise elements and tender locking are fixed on the revolving plate. 
     
     
         3 . Tenderlift according to  claim 2  characterized in that the two guide sticks stand nearer to each other than the two guide sticks. 
     
     
         4 . Tenderlift according to  claim 1  characterized in that the tender locking is carried out by means of latch lock or manually or power operated. 
     
     
         5 . Tenderlift according  claim 1  characterized in that hinges on the guide sticks, the deadrise elements and the tender locking allow these parts to plunge under the hatch means so that on the platform with the integrated revolving plate a smooth as possible surface is created. 
     
     
         6 . Tenderlift according to  claim 1  characterized in that hinged rod is fixed to one of the swivel arms and cam, resulting in a coercion rotation of the revolving plate whilst the lift stroke of the tenderlift is in operation. 
     
     
         7 . Tenderlift according to  claim 1  characterized in that instead of rod an operating cylinder comes into effect, which via a programmable controller that the revolving plate is rotated accordingly via the operating cylinder. 
     
     
         8 . Tenderlift according to  claim 1  characterized in that the cam is placed outside the centre of the revolving plate. 
     
     
         9 . Tenderlift according to  claim 1  characterized in that on the revolving plate, the platform or and/on the transom support a rail set is placed on which a movable rail mean with gliding elements is laid and which can be shifted manually or by power and can be locked by means of a rail locking device. 
     
     
         10 . Tenderlift according to  claim 1  characterized in that on the rail mean guide sticks with curved element, deadrise elements and tender locking are mounted. 
     
     
         11 . Tenderlift according to  claim 1  characterized in that the swivel arms which form a parallelogram, at least one swivel arm has a U shape, the other swivel arm lies aligned or partly nested in the other swivel arm and so that the varying gap when moving the lift stroke does not exceed the value and the U shape increases the stability of a swivel arm, as well. 
     
     
         12 . Tenderlift according to  claim 1  characterized in that a casing or and roundings on the supports or/and lift cylinders and or overlapping the flanks of the swivel arms reduce or eliminate the cutting and bruising risks. 
     
     
         13 . Tenderlift according to  claim 1  characterized in that on the transom there is a connecting ladder, which is connected to the platform, on the one hand by means of a pivot bearing on the transom and on the other hand by a pivot bearing on the guide tube which is fixed on the platform and that the pivot bearing is releasable by means of release elements. 
     
     
         14 . Tenderlift according to  claim 1  characterized in that the swivel arms can be of steel or/and aluminium or and composite material.
