DEVICE IN LOAD DECKS FOR REMOVABLY FASTENING A POST

Abstract: A device in load decks for removably fixing a post (1) in a tubular element (2), such as a lower post or sleeve mounted on a horizontal beam of the load deck, with the aid of an actuating member (4) mounted on the post. The device comprises a transfer member (3) swingably mounted inside the post (1) and including a first part (5) for actuation by the actuating member (4) and a second part (6) projecting out from the post for engagement with engagement means (2a, 2b) arranged on the inside of the tubular element (2).

Description: Technical Field The present invention relates to a device in load decks for removably fastening a post in a tubular element, such as a lower post or a sleeve mounted on a horizontal beam of the load deck, with the aid of an actuating member mounted on the post, wherein inside the post there is a transfer member which can swing backwards and forwards inside the post and which includes a first part for actuating with the aid of the actuating member and a second part projecting out from the post for engagement with engagement means on the inside of the tubular element. Background Art A large number of different devices of the kind mentioned above have been developed and utilised over the years. In such development it has been attempted to ensure that the fastening device will be reliable, easily accessible, simple and quick to operate, simple and cheap to manufacture and fit and to decrease and preferably eliminate vibrations and raffles between it, the post and the tubular element. The known devices only match up to certain of these desires or requirements. DE-A-21 53 610 discloses a fastening device as described in the introduction to claim 1. This device is complicated and expensive to manufacture because it comprises a relatively large number of details. Disclosure of the Invention The object of the present invention is to provide a device of the kind mentioned in the introduction, with which most of the abovementioned desires and requirements are met. This object is achieved by the device in accordance with the invention having been given the distinguishing features disclosed in the characterizing portions of the claims. Description of Figures The single Figure on the drawing is a longitudinal section through a part of a load deck with the device in accordance with the invention. Preferred Embodiment The hollow post of the load deck is denoted by the numeral 1, and the tubular element of the deck, which can be an upwardly open sleeve or a hollow, lower post is denoted by the numeral 2 and is fastened to an unillustrated beam in the load deck. The post 1 is telescopically displacable inside the element 2, and removably locked to it in the position illustated in the figure. The post and element suitably have square cross section. Two inwardly open recesses 2a and 2b are made in opposite walls of the upper part of the element 2 to form engagement means, which are intended to engage with a transfer member 3 mounted inside the post 1, this transfer member in turn engaging with an actuating member 4 similarly mounted on the inside of the post. In the position illustrated in the figure, the recess 2a engages with the transfer member, while the recess 2b is intended to engage with the transfer member after the post has been turned 180 o about its longitudinal axis. The transfer member 3 includes a plate 5 of spring steel or other resilient material, a body 6 of steel or hard rubber which is attached to the plate and is accommodated in a hole 1a in the post 1, there also being a shaft 7 and a compression spring 8 inside the post 1 and associated with the transfer member 3, the spring acting between the plate 5 and the wall of the post. The actuating member 4 comprises a cylinder mounted for rotation in two opposing walls of the post 1 and provided with a central recess with a flat surface 9a. A pin 10 with a quadratic cross section is fastened to one end of the cylinder 9 and is accessible from the outside of the post for removable engagement with an unillustrated turning device, such as an adjustable spanner. A projection 11 on the cylinder 10 prevents the cylinder from being turned past the plate 5. Before the post 1 is mounted and fixed to the element 2, the actuating member 4 is turned so that the plate 5 assumes, with the aid of the spring 8 a position where it engages against the surface 9a and against the shaft 7 and where the body 6 is within the outer definition of the post but still in the hole 1a so that the transfer member does not fall down in the post. After the post 1 has been inserted in the element 2 and the body 6 positioned opposite one of the recesses 2a and 2b, the actuating member 4 is turned anti-clockwise until the projection 11 comes into engagement against the plate 5, as illustated in the figure, when continued turning is not possible. During turning, the body 6 is inserted in the recess 2a or 2b and is successively pressed harder and harder against the element 2 while the plate 5 deflects and increases its spring bias. In the position illustrated in the figure, the post 1 is securely fixed in the element 2, partly by the body 6 and recess 2a or 2b preventing vertical relative movement between the body and the element and partly by the body 6 and the opposing wall of the post being pressed horizontally against the element 2 with the spring bias, which prevents rattle and vibrations occurring between the post and the element.

Claims: Device in load decks for removably fastening a post (1) in a tubular element (2), such as a lower post or a sleeve mounted on a horizontal beam of the load deck, with the aid of an actuating member (4) mounted on the post, wherein inside the post there is a transfer member (3) which can swing backwards and forwards inside the post and which includes a first part (5) for actuating with the aid of the actuating member and a second part (6) projecting out from the post for engagement with engagement means (2a,2b) on the inside of the tubular element, characterized in that the transfer member (3) is resilient and swingable about a shaft (7) fastened on the inside of the post (1), the second part (6) of the transfer member engaging under spring bias with the engagement means (2a,2b) in the actuating position of the actuating member (4). Device as claimed in claim 1, characterized in that the transfer member (3) comprises a two-armed lever (5) formed as a plate, with the first part (5) engaging against the actuating member and the second part (6) inserted in a hole (1a) made in the post (1). Device as claimed in any one of the preceding claims, characterized by a resilient element (8) for taking the second part (6) out of engagement with the engagement means (2a,2b) when the actuating member (4) is not actuated. Device as claimed in any one of the preceding claims, characterized in that the actuating member (4) comprises an eccentric.
