MOVABLE SUSPENSION FOR LADDERS - TRANSPORTABLE OPPHENGANORDNING FÖR STEGE

The invention relates to a portable suspension device for a ladder according to the preamble of claim 1.

Different types of pools are now inspected, maintained and repaired using a detached ladder that is placed on the bottom of the pool or against equipment in the pool to allow staff to enter.

Such placement of a ladder is an obstacle to both work and descent due to the oblique angle at which the ladder must necessarily be placed and the insecure support against the bottom of the pool.

Swedish patent publication 408720 discloses a ladder for use in swimming pools. The ladder has pivoting steps attached to a fastening device comprising guide sleeves, a base between the slings, a collar to be supported against the front of the basin and two pivotable supports.

The ladder according to the patent publication is based on the fact that the ladder itself can be placed against the pool, which in most cases causes a bit of difficulty, for example basic equipment placed on the bottom. Furthermore, the device according to the patent publication is large and cumbersome and suitable for a certain type of basin edge. The principle of the device according to the invention is the lateral support of vertical ladders.

In simple newer pools, there is a device in connection with the pool frame for positioning the ladder so that these are kept vertical and thus provide better access.

However, there is no such device at the older edges of the basin and secure and simple access to such basins is achieved by the movable suspension device according to the invention, as is the feature of the claims in the parts.

In the drawing, Fig. 1 shows a plan view of a suspension device with 2,72781 stacked arms and outwardly turned arms shown in broken lines, Fig. 2 shows a plan view of a second embodiment of the invention and Fig. 3 shows a side view of the device according to Fig. 1.

Arranged in the crossbeam 3 is a horizontal stop 1 for receiving a step not shown, and two vertical stops 2 for supporting ladder steps. These supports are arranged in the middle of the crossbeams in front of it.

At both ends of the beams on its rear side there are articulated points 7 and 8 around which the support arms 4 and 5 can be turned from the 27CPa position shown in full lines in Figure 1, where the support arms are parallel to the crossbeam and the device can be easily moved to the operating position shown in broken lines. in Figure 1.

In use, the device is placed in the horizontal support 1 and the vertical edge of the pool 2 from a customer, and supporting arms 4 and 5 is turned to the operating position so that they rest against the upper surface of the liner in the outer side. In this way, a very stable support is provided for a ladder which can be hung horizontally from 1 step and which descends down to the opening of the basin.

In another embodiment of the invention, the suspension device is formed of two parts, of which the cross beam 3 itself is one. There are sleeves 10 at each end of the beam 3.

The second part consists of a transverse arm 6 with support arms 4 and 5 mounted at two ends, while the support arms can be pivoted from a 90® assembled position in which they are parallel to the transverse arm 6 to a working position in which the support arms 4 and 5 are pivoted 90 ° and can be with attached pins 9 attaches to the cross member 3 by guiding the pins 9 to the sleeves 10. In this way, the suspension device is obtained by supporting around the entire basin.

Claims (2)

3,72781 1. Removable suspension device for hanging a dart through the vertical shafts, such as in pools, characterized in that the horizontal support (1) of the ladder one step and two vertical support (2) of the ladder columns is rigidly mounted a cross-beam (3), the front side of the center, wherein a cross beam is arranged to be part of the pool to the edges so that the supports are located above the opening of the basin and that the support arms (4, 5, 6) which come against the surface surrounding the basin, completely or partially around the basin, are by means of articulation points (7, 8) in the arms (4, 5, 6) foldable for transport and openable for use. Device according to Claim 1, characterized in that the support arms (4, 5) are each pivotable at their joint point (7, 8) in a horizontal plane 270 ° from the transport position in which they are substantially parallel to the cross member (3) to the working position in which they form a straight line. with the corner cross beam (3) in order to be able to come into contact with the diametrically located sides of the basin in the working position. Device according to Claim 1, characterized in that the cross arm (6) has, at both ends, articulation points (7, 8) on which the support arms (4, 5) are pivotally mounted in a horizontal plane so that the support arms (4, 5) can be rotated 90 °. from a folded position in which the support arms are substantially parallel to the cross arm (6) to a working position in which the pins (9) at the other ends of the support arms (4, 5) are insertable into corresponding sleeves (10) at the ends of the cross beam (3).
