Description

15 20 25 30 35 446 712 2 end is provided a support 8 "in the form of a simple arm. step s' is aelaa 1 two häiftez e11er_ae1ar 18,19 of which the former includes two side pieces in the form of relatively coarse tubes in which two smaller tubes included in the part 19 are inserted. In this way, the total length of the steps can be reduced from the maximum length shown in Fig. 2 to a smaller length in the inactive state shown in Fig. 1. In other words, the cassette 2 'can be made relatively short in comparison with the maximum length of the steps while achieving a minimum space requirements for the cassette.

The support arm 8 "comprises two tubular or rod-shaped parts 20, 21, the two ends of which facing each other are threaded and inserted into an internally threaded sleeve 22 of the rigging screw type. Hereby the" length of the support arm 8 "can be varied to fit boats with different bow angles. is of course also conceivable to make the length of the support arm 8 "adjustable in another way than that shown in the exemplary embodiment.

Furthermore, it should be pointed out that the arm part 21 has a V-shaped portion 21 'which is connected to the lowest step pin of the step 5' via a hinge 23, the step step in question forming a front piece in the case-setter! 2 'when SÜGQGU is retracted to its inactive state as shown in Fig. 1.

At its inner or upper end, the steps 5 'suitably have two wheels 24 which are guided in associated guides inside the cassette 2', each guide ending in a recess 25 in which the respective wheels are retained when the steps are pulled out to their active state. as follows: From the inactive state shown in Fig. 3, the steps 5 'are extended in extension of the cassette 2', the sliding body 9 'accompanying the support arm 8 "from a low position relative to the guide 4' to a high position relative thereto. The position shown in Fig. 4 is lowered down to the position shown in Fig. 5, the sliding body 9 'again sinking down to its lowest position relative to the guide 4'. Finally, the lower step part is then pulled 19 relatively extends the upper step part 18 so that the steps assume the fully extended position shown in Fig. 6, in which the same can be used for disembarkation from the respective entry of the boat 1 '.

When folding in the steps, the procedure is reversed.

Possible modifications of the invention It is a given that the invention is not limited only to the embodiment described and shown in the drawings.

Thus, instead of a cassette rod that can be mounted on an existing boat, the type shown in the drawing, other arbitrary types of holders can be used to hold or accommodate the steps in the inactive state. For example, this holder can consist of a suitably designed cavity in the hull itself of the boat as well as of an outrigger or gangway of the type shown in SE patent application 8304775-3. Furthermore, the guide in question can be designed in another way than the one shown, for example in the form of a slender rail with a surface-mounted sliding body. The steps themselves can be advantageous, but do not necessarily have to be extendable, for example in the manner shown in the drawings. Furthermore, it should be pointed out that the step construction according to the invention can also be used on units other than just boats. These can be mobile units, for example vehicles of various kinds, such as fixed units, such as loading docks and the like.

Claims (4)

10 15 20 25 30 35 446 712 PATENÆKRÅv g Step construction, preferably for boats, characterized in that in addition to a ladder (5f) it comprises both a substantially horizontal holder (2f) arranged to receive the steps in an inactive state, and a support (8f) which is partly pivotally or articulated connected to the steps (5 '), partly connected to a body (9') which is slidably or displaceably movable along a guide (4f) located at a distance from and / or at an angle to a position in which ladder hangs in the active state from the holder (2), the ladder being movable from its inactive state while moving said body (9 ') in the upward direction along the guide (4f) to an extended position in which the same can folded down to its active state, suspended from the holder, during which folding movement said body automatically slides down along the guide to a position in which the support (8 ") is able to support the steps towards pivoting in direction towards the guide. Step construction according to claim 1, characterized in that the holder consists of a cassette counter container (2f) applicable, for example, to a boat's deck in which the step (5f) is hidden in its inactive state. Step construction according to claim 1 or 2, characterized in that the steps (S ') comprise two halves or parts (18, 19) which are suitably telescopically displaceable relative to each other in order on the one hand to allow shortening of the steps to a minimum length in its inactive state and on the other hand allow extension of the steps to a maximum length in its active state, whereby the holder or KäSSe fi teM2f) can be given small dimensions for a given maximum length of the steps. 10 446 712 Step construction according to any one of the preceding claims, characterized in that the support comprises an arm (8f ') composed of at least two parts (20, 21) which are adjustable and lockable in different positions relative to each other to enable adjustment of the arm. length and thus an adaptation of the arm to boat poles with different angles of inclination.
