Description

STANCHION

TECHNICAL FIELD

The present invention refers to a stanchion for a platform body or the like. The stanchion has a first end and a second end. The stanchion incorporates a stanchion housing and a locking device incorporating a lever. A first locking member is displaceably arranged in at least a portion of the lever and arranged to cooperate with a platform attachment in connection to the platform body between at least a locked position and an unlocked position with reference to the platform attachment for locking the first end of the stanchion to the platform attachment. The lever is pivotably arranged at the stanchion housing about a pivot axis.

BACKGROUND OF THE INVENTION

Detachable stanchions are usually used on lorry platforms for attaching sideboards, tarpaulins or other equipment to the lorry platform. Detachable stanchions are superior at the daily handling when compared to fixedly attached stanchions, as they can be removed, pushed aside or displaced in other manners, thus that the lorry platform can be easily loaded or unloaded. One type of detachable stanchions are suspended at one of its ends from a frame part, which extends at least partly above and along the edge of the lorry platform. Such detachable stanchions are displaceable along the frame thus that the stanchions can be moved in order not to be an obstacle at loading or unloading of goods. The stanchions are usually heavy and therefore ungainly, particularly if a tarpaulin is fitted to the stanchion. Such a detachable stanchion has also a locking device for detachably attaching the stanchion to the lorry platform. There are a number of solutions for such locking devices.

Locking devices of the type just mentioned usually require quite a large space for the internal volume of the stanchion. This problem will be particularly evident in the cases when lorry platform covers, such as a tarpaulin, or an attachment device for a lorry platform cover, is fitted to the stanchion. As the stanchions - as earlier mentioned - furthermore can be rather heavy, it might be difficult to position them at a correct position for locking e.g. to a lorry platform.

RECORD COPY-TRANSLATION (Rule 12,4) In order to solve the this problem, earlier technique according to the Swedish patent application SE0801773-3, filed on August 8, 2008, proposes to offer a stanchion, which has a locking device with a lever, where the lever is turnable in relation to the stanchion and where a locking between the stanchion and the platform is effected via the lever. With a stanchion as described above, fitting and releasing of the stanchion are facilitated.

At transport of goods, there is however a risk that at least a part of the goods is displaced towards one or more of the stanchions on the lorry platform. As the lever is turnable in relation to the stanchion and the stanchion is arrested to the platform via the lever, there is for this reason a risk that the stanchion is turned in relation to the platform due to the load from the displaced goods.

It should be noted that there is a risk that the stanchion is turned out from lorry platform as well as inwardly towards the lorry platform due to transverse load for instance from displaced goods. This because the stanchions on the lorry platform often are interconnected via the earlier mentioned frame part, thus that a turning of stanchions outwards from the platform at one side of the lorry platform can result in that stanchions at the opposite side of the platform being turned inwards. In order to solve this problem, SE0801773-3 proposes that the locking device is equipped with turning locks at the upper edge of the lever for thereby preventing the stanchion from being turned relative to the lever. This turning lock is activated after the fitting of the lever to the platform attachment.

Even if the solution according to SE0801773-3 offers a stanchion which is easily fitted to a platform and also gives an appropriate resistance to lateral loads against the stanchion, it should be desirable to offer a stanchion having still better properties, for instance with reference to the resistance against lateral loads.

SUMMARY OF THE INVENTION

A first purpose of the present invention is to offer a stanchion for a load platform or the like, where the stanchion has a locking device, which incorporates a lever, which is turnable in relation to a stanchion housing of the stanchion, where the stanchion housing and the lever are prevented from mutual turning, as soon as the stanchion is locked to the load platform.

A second purpose of the present invention is to offer a stanchion for a load platform or the like, where the stanchion has a locking device, which incorporates a lever, which is turnable in relation to a stanchion housing of the stanchion, where the stanchion has a sturdy stop against turning of the stanchion housing in relation to the lever when the stanchion is locked to the load platform.

At least one of the above purposes is achieved in accordance with claim 1.

Thus the present invention refers to a stanchion for a load platform or the like. The stanchion has a first end and a second end. The stanchion incorporates a stanchion housing and a locking device incorporating a lever. A first locking member is arranged to be displaceable inside at least a part of the lever and arranged to cooperate with a platform attachment in connection to the load platform between at least a locked position and an unlocked position with reference to the platform attachment for locking the first end of the stanchion to the platform attachment. The lever is arranged to be turnable relative to the stanchion housing about a turning axis.

In accordance with the invention, the stanchion further incorporates a stop device incorporating a first stop device part and a second stop device part, where the first stop device part is rigidly connected to the first locking member. The first and second stop device parts are arranged to come into engagement for preventing turning of the lever in at least a first direction about the turning axis in relation to the stanchion housing when the first locking member is in the locked position.

The meaning of the expression "rigidly connected" in the present patent application, is that the first stop device part is connected to the first locking member thus that it will undergo a displacement which is substantially uniform with - i.e. substantially directed in the same direction and having a size which is at least proportional to - the displacement of the first locking member, during at least a part of the displacement when the locking member is displaced from its unlocked position to its locked position.

As the first stop device part is rigidly connected to the first locking member, a turning of the lever relative to the stanchion housing is prevented as soon as the first locking member is fitted to the platform attachment. This will facilitate fitting of the stanchion to the load platform and increases furthermore the safety at an arresting procedure.

As the first stop device part is rigidly connected to the first locking member, it is furthermore possible to obtain a compact stop device. This is preferred as at least the first stop device part often is arranged to be positioned inside the lever.

According to as preferred embodiment of the present invention, the stanchion housing incorporates a first portion which extends from the first end of the stanchion to the turning axis, whereby the second stop device part is fixedly connected to the first portion of the stanchion housing.

In another preferred embodiment of the present invention, the lever incorporates a recess for accommodating the second stop device part inside the lever when the lever extends substantially in parallel with the stanchion housing.

In a further embodiment of the present invention, the first locking member is arranged to be displaceable inside at least a portion of the lever from the unlocked position to the locked position in a first direction, whereby the first stop device part is situated below the first locking member as seen in the first direction.

In another embodiment of the present invention, the first stop device part incorporates a flange and the second stop device part incorporates a dowel rod.

According to a preferred embodiment of the present invention, the stanchion further incorporates a stop device incorporating a first stop device part and a second stop device part, where the first stop device part is rigidly connected to the first locking member. The step of arresting the lever incorporates a step to force the first stop device part to make a displacement, which is substantially uniform with the displacement of the first locking member from the unlocked position to the locked position, thus that the first stop device part will come to engagement with the second stop device part for preventing turning in at least a first direction about the turning axis of the lever in relation to the stanchion.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The invention will be described by means of examples of embodiments. However it shall be understood that those embodiments only serve for elucidating the present invention, the scope of protection of which is limited by the accompanying claims.

In Fig. 1 is shown a stanchion 10 according to the invention, which hereinafter will be described with an embodiment in combination with a lorry platform 2, but the present invention can be applied to any load platform. A stanchion 10 according to the present invention is preferably used in combination with a frame part 1 , which supports a weather protection, such as a tarpaulin. Such a frame part 1 extends along the periphery of the lorry platform 2, and at least along the longitudinal sides of the lorry platform 2.

The stanchion 10, which has a first and a second end 11 , 12 is displaceably fitted at one of its ends to the frame part 1 and the first end 11 of the stanchion 10 can at a desired position be locked in connection to the edge of the lorry platform 2 in a platform attachment. In Fig. 1 is shown only one stanchion, but it is usual to have several stanchions of the same or similar type, as the stanchion 10. Between the stanchions is preferably arranged a weather protection for protecting the cargo space from non- desired contaminations. The stanchions therefore can be removed from the lorry platform and displaced along the frame part 1 until a desired opening has been achieved in the weather protection of the lorry platform 2. Goods can thereupon be unloaded from and loaded on the lorry platform 2 in a simple manner. The stanchion 10 incorporates a locking device 20 for detachably locking the first end 11 of the stanchion 10 to a platform attachment provided in connection to the lorry platform 2. The locking device 20 will hereinafter be described more in detail. The stanchion 10 furthermore incorporates a stanchion housing 9. The stanchion housing 9 extends between at least a portion of the distance between the first end 11 of the stanchion 10 and the second end 12 of the stanchion and usually the length of the stanchion housing constitutes a major part of the length of the stanchion 10. The expression length, in this context means a distance in a direction between the first 11 and second end 12 of the stanchion. As a non-limiting example, it can be mentioned that the length of the stanchion housing 9 can be at least 50%, preferably at least 70% of the length of the stanchion 10. In the cases where the stanchion housing 9 only constitutes a part of the length of the stanchion 10, the remaining part of the length can be constituted by for instance coupling elements, such as the coupling element 13 shown in Fig. 1 for coupling the stanchion 10 to the frame part 1.

As a further non-limiting example, it can be mentioned that the stanchion housing 9 preferably is constituted by a metallic tube having for instance a U profile or a quadrangular profile. With reference to Figs. 2A - 5C, the very fitting principle and function of the locking device 20 will be described more in detail. In Fig. 2A - 5C is shown a sequence where the stanchion 10 is attached to a lorry platform and a person skilled in the art will understand that disconnection of the stanchion 10 is effected in reversed order. As can be seen from for instance Fig. 2A, the stanchion 10 has a first end 11 and a second end 12. The stanchion 10 furthermore incorporates a stanchion housing 9 and a locking device 20, incorporating a lever 21. The lever 21 is arranged to be turnable at the stanchion housing 9 about a turning axis R1 , which turning axis R1 is shown in Fig. 2B.

Fig. 2C shows the locking device 20 of the stanchion 10 more in detail. From Fig. 2C it can among other things be seen that the stanchion has a first locking member 33, which is arranged to be displaceable in at least a part of the lever 21 and which is arranged to cooperate with a platform attachment 50 in connection to the load platform (not shown) between at least a locked position and an unlocked position with reference to the platform attachment 50 for locking the first end 11 of the stanchion to the platform attachment 50.

As lorry stanchions usually are rather heavy, the frame part from which a stanchion 10 is suspended might be somewhat deformed, intently or non-intently, which means that the stanchion might have to be lifted to a locking-in level for positioning the first locking member 33 in correct locking position, and this has been indicated in Fig. 2C with arrows in connection to the stanchion housing 9. The lever 21 then will be of good help for giving a leverage for the stanchion housing 9 about the turning axis R1 , for this purpose.

A preferred design of the locking device 20 furthermore incorporates a control handle 30, which is arranged to be pivotable relative to the lever 21. This control handle 30 will act as an extended lever arm for the lever 21 , when the control handle 30 is in the position shown in Fig. 2C. By using the control handle 30 as an extended lever arm for the lever 21 , the required force which must be applied to the stanchion for positioning at least the first locking member 33 in position for locking the stanchion 10, is reduced. The control handle 30 furthermore acts as a support when unlocking the stanchion 10. In Fig. 3A - 3D is shown how the lever 21 has been moved substantially into the stanchion housing 9 thus that the lever 21 is substantially in parallel with the stanchion housing 9. The first locking member 33 now is in position for being locked to the platform attachment 50. In the embodiment of the stanchion 10 shown in Fig. 3C can for instance the locking member 33 now be displaced in a first direction V, which first direction is facing substantially downwards in the embodiment shown in Fig. 3C, for locking the first locking member 33 to the platform attachment 50.

In the embodiment of the locking device 20 shown in Fig. 3C, the displacement of the first locking member 33 from an unlocked position to a locked position, can be effected in that the control handle 30 is displaced from a first position, which position is shown in Fig. 3C to a second position, which other position is shown for instance in Fig. 4C. According to this embodiment the control handle 30 thus makes a movement directed outwards and downwards in relation to the stanchion housing 9, whereby this movement is transferred to the first locking member via a coupling portion 40, which is pivotably connected to the control handle 30 and to the first locking member 33, respectively. In other embodiments of the present invention, the displacement of the first locking member 33 could however be effected in other manners, for instance via a control member (not shown), which is rigidly connected to the first locking member 33, which control member is arranged to be displaced in the first direction V for locking the first locking member 33.

From for instance Fig. 3C and Fig. 3D it can be understood that the stanchion 10 according to the present invention incorporates a stop device 37 incorporating a first stop device part 38 and a second stop device part 39 where the first stop device part 38 is rigidly connected to the first locking member 33. In the embodiment shown in Fig. 3C the rigid connection is effected between the first locking member 33 and the first stop device part 38 by means of a coupling plate 4, which is fixedly connected both to the first locking member 33 and to the first stop device part 38. This rigid connection could however be effected also in other manners, e.g. in that the first locking member 33 and the first stop device part 38 are fixedly connected to each other by means of one or several rods (not shown).

From Figs. 3C and 3D it can furthermore be understood that the first stop device part 38, in the embodiment shown therein, is situated below the first locking member 33 in the first direction V. For instance from Fig. 2C it can furthermore be understood that the stanchion housing 9 incorporates a first portion 9', which extends from the first end 11 of the stanchion 10 to the turning axis R1 and that the second stop device part 39 is fixedly connected to this first portion 9', preferably by means of for instance a welding joint, a bolt or a glue joint (not shown). However, also the second stop device part 39 could be made in one piece with the stanchion housing 9.

In the embodiment shown in Fig. 3C and 3D, the first stop device part 38 incorporates a flange and the second stop device part 39 a dowel rod, which dowel rod is fixedly connected to the stanchion housing 9. It can furthermore be seen from Figs. 3C and 3D that the lever 21 incorporates a recess 45 for accommodating the second stop device part 39, that is in this case the dowel rod, inside the lever 21 when the lever 21 extends substantially in parallel with the stanchion housing 9.

Figs. 4A - 4D show the stanchion when the first locking member 33 is in locked position with reference to the platform attachment 50. From Fig. 4D it can be seen that when the first locking member 33 is situated in this locked position, the first 38 and second 39 stop device parts are in engagement with each other in order to prevent turning of the lever 21 in relation to the stanchion housing 9, in at least a first direction about the turning axis R1.

Thus, if the upper end of the stanchion housing 9 should be subjected to an inward displacement toward the load platform to which the stanchion is fitted - this direction is indicated by the arrow R' in Fig. 4C - the second stop device part 39 will engage the first stop device part 38, which in turn will contact against the lever 21. In other words, in addition to the turning axis R1 , a further contact point or surface is provided between the stanchion housing 9 and the lever 21 , whereby the displacement of the upper end of the stanchion housing 9 in towards the load platform is prevented. It should also be mentioned that the displacement of the upper end of the stanchion housing outwardly from the load platform - this direction is indicated by the arrow R" in Fig. 4C - will be prevented by a contact force between the stanchion housing 9 and the load platform, on which load platform the platform attachment 50 is mounted.

Thus the lever has been prevented from turning both in a first and a second direction (R', R") about the turning axis R1 , at the same time as the first locking member 33 is displaced from its unlocked position to its locked position.

In Figs. 5A to 5C the locking member 20 is shown in its completely locked position. As can be seen for instance from Fig. 5C the lever is locked from turning at least at the turning axis R1 also by means of a second locking member 34, which is situated at the upper edge of the lever 21.

In Figs. 6A - 6C the locking device 20 is shown, for the sake of clarity, free from the stanchion housing 9, in a locked position. The locking device 20 incorporates a lever 21 incorporating a first and a second end 22, 23. The lever 21 has also a transverse center line T, which defines a first and a second part T₁, T₂ of the lever 21. The lever 21 is arranged to be turnable to the stanchion housing 9 via a turning axis R1 , shown in Fig. 2B, about which the lever 21 can be turned in relation to the stanchion housing 9. In the described embodiments of the present invention, the lever 21 is pivotably attached to the stanchion housing 9 via a first and a second connecting journal 51 , 51 (shown in Fig. 6A). As the turning axis R1 is arranged at a distance of about 30% of the overall length of the lever 21 measured from the second end 23 of the lever 21 , is it possible that the lever 21 can give a good leverage at turning of the lever 21 when the stanchion is released from or affixed to the platform attachment. The lever 21 has a first and a second opposite wall 25, 26 and a third and a fourth opposite wall 27, 28 and has a substantially oblong form with a rectangular cross-section. The first, second, third and fourth wall 25, 26, 27, 28 define an inner volume 29 in the lever 21. A contact surface 24 is provided in connection to the second end 23 of the lever 21. The contact surface 24 is arranged to engage a surface in connection to the lorry platform, in this case the platform attachment, at locking and positioning of the stanchion 10.

The locking device 20 has a control handle 30. The control handle 30 has a first and a second end 31 , 32, whereby the first end is arranged to be indirect turnable on the lever 21. The control handle 30 is furthermore articulated to a first and a second locking member 33, 34, which is shown for instance in Figs. 6C, 7C and 8C. The first locking member 33, as earlier mentioned, is arranged to be affixed to a platform attachment and the purpose thereof is to attach the stanchion 10 to the lorry platform 2. As can be seen, the first locking member 3 is substantially wedge-shaped in its locking functional part, which means that the first locking member 33 can be easily wedged into a corresponding shape on the platform attachment 50. The second locking member 34 is arranged to lock the second end 22 of the lever 21 to the stanchion housing 9 for giving rigidity to the stanchion 10 and prevent motion of the stanchion 10 in a direction towards the lorry platform 2 when the locking device 20 is in a completely locked position. As shown for instance in Fig. 6C or alternatively in Fig. 7C, the first end 31 of the control handle 30 is connected to the second locking member 34 via a shaft journal 35 by means of which the first end 31 of the control handle 30 will be connected to the lever 21 in an indirect turnable manner.

In Figs. 6A - 6C is also shown a part of a preferred design of a first stop device part 38. As can be understood from the example shown in Fig. 6A₁ the first locking member 33 incorporates two member sections 33', 33", where each one of these member sections 33', 33" is each connected to one flange 38', 38", also referred to as stop flange, via a coupling member 44', 44", which coupling members 44', 44" in the example shown in Figs. 6A - 6C are constituted by a plate. Thus the first stop device part 38 in the embodiment shown in Figs. 6A - 6C incorporates two stop flanges 38', 38".

Furthermore it can be seen from Fig. 6A that the lever 21 incorporates two recesses 45', 45", which are situated at substantially the same level, as seen in the first direction V, as the two stop flanges 38', 38", when these flanges are situated in the position for preventing turning of the stanchion housing 9 in relation to the lever 21. The purpose and the function of the stop flanges 38', 38", which are together incorporated in the first stop device part 38, and the recesses 45', 45" have already been described in connection to Figs 2A - 5C. Furthermore it can be understood from e.g. Fig. 6A that in the design of the locking device 20, which is shown therein, the first stop device part 38 is situated between the first locking member 33 and the contact surface 24 when the locking device 20 is in a locked position.

With reference to Fig. 7C, a spring 36 is provided between the second locking member 34 and a connecting flange provided at the lever 21 in the space around the transverse centre line T of the lever 21. The spring 36 exerts when in tensioned state a pulling force on the second locking member 34 in a direction towards the second end 23 of the lever 21. A coupling portion 40 incorporating a first and a second end 41 , 42, are articulated at its first end 41 to the first end 31 of the control handle and in connection to the shaft journal 35, but between the shaft journal 35 and the second end 32 of the control handle 30. The second end 42 of the coupling portion 40 is so articulated to the first locking member 33, that, under use, the movement of the control handle 30 can be transferred to the first locking member 33 for change-over between a locked and an unlocked position. Due to the positioning of the shaft journal 35 and the positioning of the first end 41 of the coupling portion 40 in relation to each other, the spring 36 will also exert a force on the control handle 30 in its opening and closing direction depending on, on which side of the articulated fixation of the first end 41 of the coupling portion 40, it is with reference to a plane parallel to the first wall 25 of the lever 21. The coupling portion 40 extends through the plane for the first wall 25 of the lever 21 through an opening 46, in dependency of the position of the control handle 30. Said opening 46 will also function as a storage compartment for the control handle 30, thus that the control handle 30 can be positioned at the same plane as the first wall 25 of the lever 21 , which is shown for instance in Fig. 6C. The second end 32 of the control handle 30 has a hole through which a user can insert a finger for reaching the control handle 30 under use.

The second end 32 of the control handle 30 can be transferred in the longitudinal direction of the lever 21 between at least three different positions, which will be described in the following. By moving the control handle 30 between the at least three different positions it is possible to obtain at least three different positions for the first and the second locking members 33, 34. When the control handle 30 is in its first position, which is shown in Figs. 6A - 6C, both the first and the second locking member 33, 34 are in their locked positions, i.e. they are locked in such a manner that they shall prevent that the lever 21 can be turned relative to the stanchion housing 9 around the turning axis R1 , and that the lever is fixed to the platform attachment for giving stability to the stanchion 10. It can further be seen from Figs. 6A - 6C that the first stop device part 38, incorporating the two stop flanges 38', 38", is in a locked position, i.e. a position where the first stop device part 38 is arranged to come to engagement with a second stop device part 39 for preventing turning of the lever 21 in relation to the stanchion housing 9 in at least one direction around the turning axis R1.

When the control handle 30 is in its second position, which is shown in Figs. 7A - 7C, the second locking member 34 is in its unlocked position whereas the first locking member 33 is still in its locked position. This is of big importance for safety regarding the handling when unlocking and locking a stanchion in accordance with the present invention. In spite of the fact that the second locking member 34 has been displaced to its unlocked position, i.e. it is no longer in locking position relative to the stanchion 10, the first locking member 33 is still in its locked position. By keeping the first locking member 33 in its locked position the stanchion 10 will be kept fitted to the lorry platform 2 via the platform attachment. Furthermore, in the position shown in Figs. 7A - 7C, the first stop device part 38 still will prevent turning of the lever 21 in relation to the stanchion housing 9 in at least one direction about the turning axis R1.

When the control handle 30 is in the third position, which is shown in Figs. 8A - 8C, the first and the second locking members 33, 34 are in their unlocked positions. In this position the stanchion 10 is free to be disconnected from the platform attachment and can thereupon be easily pushed to the side under suspension from the frame part 1 for offering an opening suited for loading and unloading of goods. Furthermore the first stop device part 38 is in an open position, i.e. a position, which will not prevent turning of the lever 21 in relation to the stanchion housing 9 in at least one direction around the turning axis R1.

It is understood that the present invention is not limited to the embodiments, which are described here above and shown in the drawings, but an expert in the field will rather discover that many changes and modifications can be effected within the scope of protection defined in the accompanying claims.
