[0001] DESCRIPTION

[0002] A SUPPORT FOOT FOR THE SUPPORT LEGS OF TRAILERS, SEMI-TRAILERS AND SIMILAR LOAD TRANSPORT VEHICLES

[0003] Technical Field of the Invention

[0004] The invention relates to a support foot, in particular to a pivoting support foot for providing ground support for the support legs of the load transport vehicles such as truck beds, prime movers, trailers, and semi-trailers.

[0005] Background of the Invention

[0006] Vehicles such as trailers and semi-trailers are load transport vehicles that are towed by a motor vehicle. Examples of such load transport vehicles also include prime movers and truck beds. Said load transport vehicles may be parked for a wide range of purposes, such as customs clearance, storage, or general parking. In order that the towing vehicle is not occupied during parking, the towing vehicle is separated from the load transporter. Load transporters are equipped with support legs so that the load transporter can be stabilized without a towing vehicle. The support legs are lowered to the ground and thus they support and stabilize the load transporter at the front side where the towing vehicle is attached. The braking systems on the load transporter ensure that the load transporter remains stable in place.

[0007] During a long period of parking, it is likely to have brake leaks, especially in air brake systems, or loss of air in the wheels. In such cases, the load transporters move forward or backward, and there may be a change in the balance. In addition, in crowded parking areas, forklifts and other similar vehicles may hit and damage the load transporters. Similarly, such impact may also cause the load transporters to move forward or backward. The support legs therefore include pivoting support feet that can compensate said forward or backward movement, allowing the load transporter to be stabilized.

[0008] The pivoting support feet in the prior art have a high resistance to vertical forces (the force generated by the weight of the load transport vehicle), but they are highly vulnerable to lateral forces. Load transport vehicles may be exposed to lateral forces from forklifts and similar vehicles, especially during loading / unloading. The stress generated by the lateral force may cause the support leg to bend or break over time, thereby leading to accidents. The pivoting support feet have a base plate, being the part that stands on the ground. Due to various conditions, the base plate may be separated from the support feet. For example, once a towing vehicle is connected to a parked load transporter, the support legs should be pulled upwards to separate them from the ground. In case it is neglected to pull the support legs upwards, it is likely that the base plate may be broken as a result of the movement of the load transporter towed by the towing vehicle. In addition, the base plate may also be lost due to theft.

[0009] As the weight of the load transporter increases, transportation costs also increase with the increasing weight. In addition, there are weight quotas or maximum weight limits in many transportation legislation. The high weight of the support feet will result in the inability to carry the loads at the said limits, and consequently affect the quality of the transportation that can be carried out. Therefore, the consumers on one hand demand the support feet to be as light as possible, but also durable for a long-term use.

[0010] Due to the shortcomings of the pivoting support feet in the prior art, there is a need in the art for a lightweight and durable pivoting support leg with increased resistance against lateral forces, which is capable of supporting the load transporter without a base plate.

[0012] A main object of the present invention is to provide a support foot capable of supporting load transport vehicles without a base plate.

[0013] Another object of the invention is to provide a lightweight and durable support foot.

[0061] The invention relates to a lightweight, motion-compensating, pivoting support foot (100) with increased resistance against lateral forces, which is capable of supporting a load transport vehicle without a base plate (200).

[0062] In the embodiments of the invention, the term load transport vehicle refers to vehicles such as truck beds, prime movers, trailers, semi-trailers, etc.

[0063] The invention relates to a support foot (100) for providing ground support for support legs (SL) of trailers or similar load transport vehicles, wherein the support foot (100) comprises a base plate (200) and at least two guide walls (300) extending substantially perpendicularly from two sides of the base plate (200), each having at least one guide opening (310). The support foot (100) also comprises at least two side walls (410) with convex edges facing the base plate (200), which extend substantially perpendicular to the base plate (200), and which are positioned between the guide walls (300); a swing unit (400) with a rolling plate (420) connecting the side walls (410) at their convex edges; at least two oscillation springs (500) connecting the base plate (200) and the swing unit (400); at least two spring openings (421) at the rolling plate (420) through which the oscillation spring (500) is passed; at least two coaxial pin openings (411) provided in each of the side walls (410); at least one guide pin (412) passing through the pin openings (411), the ends of which are located in the guide openings (310); two coaxial mounting openings (413) provided in each side wall (410) for rotatably accommodating a mounting shaft (440); a rolling support (320) provided on an inner edge surface of the base plate (200), and which forms a surface for the rolling plate (420) to roll thereon.

[0064] The support foot (100) consists of two main parts, i.e. the base plate (200) and the swing unit (400). The swing unit (400) is for pivotably fixing it at one side to the support leg (SL) of a load transport vehicle. The swing unit (400) is reliably connected to the base plate (200) at the other opposite side. A reciprocating movement of the load transport vehicle is compensated by the rolling of the swing unit (400) on the base plate (200) (see Figs. 2-7).

[0065] The base plate (200) is the part of the support foot (100) that will be in contact with the ground. The base plate (200) will be in contact with the ground on an outer surface thereof. The base plate (200) is preferably in the form of a rectangular, flat plate. The guide walls (300) extend essentially perpendicularly on both sides inside the base plate (200). For the rectangular base plate (200), the two sides of the base plate (200) may be those with the long edges (see Fig. 1). Each guide wall (300) comprises at least one guide opening (310). The guide wall (300) is fixed to the base plate (200). This fixing is preferably carried out by welding. An open edge of the guide wall (300) preferably has a convex form.

[0066] The swing unit (400) comprises at least two side walls (410) and a rolling plate (420) connecting the side walls (410). The side walls (410) extend substantially perpendicular to the base plate (200) and are positioned between the guide walls (300). Each side wall (410) has a convex edge facing towards the base plate (200). In a preferred embodiment of the invention, the side walls (410) are preferably in the form of a half-disk or a part of a disk (see Fig. 12). The rolling plate (420) connects the side walls (410) at their convex edges. The rolling plate (420) is in the form of an arc-shaped plate. The convex edge form of the side walls (410) and the arc-shaped plate form of the rolling plate (420) create a suitable form for the swing unit (400) to perform the rolling / swinging movement performed on the base plate (200).

[0067] A semi-open box form is formed for the swing unit (400) by the two side walls (410) and the rolling plate (420) connecting the side walls (410). The semi-open box form gives the swing unit (400) the strength to support the weight from the load transport vehicles even without the base plate (200). However, given that it is in the form of a plate, e.g. a sheet, the rolling plate (420) has a large surface area. Therefore, the weight can be distributed and transmitted to the ground through this large surface area. Thus, it is possible to retain the support foot (100) stabilized on the ground without sinking into the ground, even without the base plate (200). In cases where the base plate (200) is stolen or detached from the support foot (100), the rolling plate (420) rests on the ground so that the support foot (100) supports the support legs (SL).

[0068] The swing unit (400) can perform oscillating and rolling movement on the base plate (200). During the oscillating and rolling movement, the swing unit (400) and the base plate (200) are held together by at least two oscillation springs (500) and at least one guide pin (412). The oscillation springs (500) are mutually located on either side of the rolling plate (420). The oscillation springs (500) are positioned in the rolling plate (420) on either side of the mounting opening (413). The oscillating spring (500) is fixed at one end to the rolling plate (420) and at the other end to the base plate (200). Holding the swing unit (400) and the base plate (200) together during the oscillating and rolling movement is guaranteed by means of the guide pin (412). Each of the side walls (410) has at least two coaxial pin openings (411). The guide pin (412) passes through the pin openings (411) and connects the side walls (410) in a physical manner. Such physical connection between the side walls (410) realized by the rolling plate (420) is supported by an additional physical connection realized by the guide pin (412). This increases the strength of the swing unit (400). The length of the guide pin (412) is greater than the distance between the side walls (410). Therefore, both ends of the guide pin (412) protrude from a surface of the side walls (410). The guide pin (412) is engaged into (passed through) the guide opening (310) via the protruding end. The protruding end of the guide pin (412) follows a path of pattern in the plane of the guide wall (300) based on the oscillation and rolling movement of the swing unit (400). The guide opening (310) is shaped to follow the pattern path and guides the guide pin (412) along the pattern path. In an exemplary embodiment of the invention, the pattern path and thus the guide opening (310) are in the form of a V or a wide V with rounded edges. During the oscillation and rolling movement of the swing unit (400), the protruding end of the guide pin (412) follows the form of the guide opening (310) and moves in the guide opening (310). Thus, the physical connection between the swing unit (400) and the base plate (200) is continuously maintained throughout the oscillating and rolling movement.

[0069] The rolling support (320) is located on an inner edge surface of the base plate (200). The rolling support (320) is preferably in the form of a sheet / plate, a longitudinal sheet / plate or a strip-shaped sheet / plate. The rolling support (320) may extend along an inner edge of the base plate (200). The rolling support (320) provides a surface for the rolling plate (420) to roll thereon. The rolling support (320) has an elongated rectangular form for the rectangular base plate (200). The rolling plate (420) rolls on a layer formed by the base plate (200) and a layer of the rolling support (320) located above the former. The thus formed two-layer structure significantly increases the strength of the support foot (100) (see Figs. 15-16). The entire base plate (200) can be manufactured in the thickness of the said two-layer structure. However, this will increase the weight of the base plate (200) and therefore the weight of the support foot (100). In addition, extra material will increase the cost of production.

[0070] The support foot (100) in an embodiment of the invention comprises a rolling support (320) integral with the guide wall (300), forming a L-shape with the guide wall (300). In this embodiment of the invention, the rolling support (320) is an integral (indivisible, unitary) part of the guide wall (300). The L-shape formed by the rolling support (320) and the guide wall (300) (see Figs. 14-15) additionally increases the resistance of the guide wall (300) against lateral forces. In an embodiment of the invention, a stiffening rod may be located at an inner corner of the L-form, at the ends of the rolling support (320), which connects the rolling support (320) to the guide wall (300).

[0071] The support foot (100) of an embodiment of the invention comprises at least one swing spring holder (422) disposed on a concave surface of the rolling plate (420), to which an end of the oscillation spring (500) is connected, and a base spring holder (210) disposed on an inner surface of the base plate (200). During the rolling movement of the swing unit (400), there occurs a change in a projection of the oscillation spring (500) on the rolling plate (420). During the rolling movement and the change in projection, the oscillation spring (500) should not rub against the rolling plate (420). Therefore, a spring opening (421) must be provided in the rolling plate (420), which is dimensioned so as not to allow the oscillation spring (500) to rub against the rolling plate (420) during the rolling movement. As the spring opening (421) increases, the surface area of the rolling plate (420) will be reduced. The reduction in the surface area will reduce the strength of the rolling plate (420) and its ability to hold on the ground without sinking into the ground in the absence of the base plate (200). It is therefore desirable to use a spring opening (421) of the smallest size. In order to fulfill this request, in a variant of this embodiment of the invention, the support foot (100) comprises a swing spring holder (422) extending from the concave surface of the rolling plate (420), and forming a selected distance between an end of the oscillation spring (500) connected to the rolling plate (420) and the concave surface of the rolling plate (420). The translation of the swing spring holder (422) from the plane of the rolling plate (420) reduces a size of the projection of the oscillation spring (500) on the rolling plate (420) during the rolling movement of the swing unit (400). Thus, an oscillation spring holder (422) is formed which is smaller than that required by the oscillation spring (500) connected to the plane of the rolling plate (420).

[0072] In an embodiment of the invention, the support foot (100) comprises edge walls (220) extending from the edges of the base plate (200), and which together with the base plate (200) form a form of a tray. The edge walls (220) significantly increase the strength of the base plate (200). The thus created tray form provides an additional contribution to prevent the base plate (200) from sinking into the ground. However, in a variant of this embodiment of the invention, the support foot (100) comprises edge walls (220) on either side of the base plate (200) that are parallel, adjacent and integral with the guide wall (300). Here, the angles between the base plate (200) and the edge walls (220) on either side are essentially 90°. The edge walls in this embodiment support the guide wall (300) against lateral forces. This significantly increases the resistance of the support foot (100) against lateral forces.

[0073] The support foot (100) in an embodiment of the invention comprises an abutment shaft (430) that connects the side walls (410) to each other, that is fixed on both sides of the mounting opening (413), and defines the maximum rotation angle of the swing unit (400), for abutment on the support leg (SL) when the swing unit (400) is at the maximum rotational angle. In order to prevent the support foot (100) from tipping over, the angle of rotation of the swing unit (400), i.e. an amount of rolling, must be limited. Such limitation can be realized by means of the guide openings (310) and the guide pin (412). A space in which the ends of the guide pin (412) can advance is limited by the guide opening (310). Again, such limitation can also be realized by the rolling plate (420) abutting on the base plate (200). However, in order to increase the service life of the guide openings (310) and guide pin (412) and to realize a more stable limitation, especially when carrying heavy loads, a mounting shaft (430) is used. During the oscillation and rolling movement of the swing unit (400), when the swing unit (400) is at a selected maximum rotation angle, the abutment shaft (430) abuts on the support leg (SL), and the swing unit (400) is prevented from rotating further in the same direction. The position at which the abutment shaft (430) is connected to the side walls (410) defines the maximum rotation angle. The selected maximum rotation angle can be defined by selecting the position where the abutment shaft (430) is connected to the side walls (410).

[0074] In an embodiment of the invention, the support foot (100) comprises a mounting opening (413) having a surface with a wall thickness greater than a wall thickness of the side wall (410). The support foot (100) in embodiments of the invention is preferably made of steel. One of the most important objects of the invention is to provide a support foot (100) that is as light as possible. Therefore, a principle is adopted in that the wall thickness of the sections of the support foot (100) where the stress caused by the load applied thereon is kept greater than the wall thickness of the sections where the stress is distributed. Thus, the strength of the support foot (100) is kept at a high level while its weight is significantly reduced. One of the sections of the support foot (100) that is subjected to high levels of stress is the mounting opening (413). The entire load on the support legs (SL) is transferred to the mounting opening (413) via the mounting shaft (440). The fact that this high stress is also supported extends the service life of the support foot (100). In a variant of this embodiment of the invention, the support foot (100) comprises a support ring (414) coaxial with the mounting opening (413), adjacent to and integral with the mounting opening (413), which allows the wall thickness of the surface of the mounting opening (413) to be greater than the wall thickness of the side wall (410). The integration of the support ring (414) and the mounting opening (413) can be performed by welding. The support ring (414) can be a washer.

[0075] In the embodiments of the invention, the side walls (410) comprise a mounting opening (413) for pivotably accommodating a mounting shaft (440). In an embodiment of the invention, the support foot (100) comprises a tubular mounting shaft (440) passing through the mounting openings (413), which is pivotably disposed in the mounting openings (413) and has at least two shaft lockers at each end thereof. In a variant of this embodiment of the invention, the support foot (100) comprises a shaft locker having two coaxial shaft locking holes (441) and a cotter pin (442) passing through the shaft locking holes (441). In the assembly of an exemplary embodiment of the invention, there is provided a shaft bearing at one end of the support leg (SL) to which the support foot (100) is to be connected, for accommodating the mounting shaft (440). The mounting of the support foot (100) to the support leg (SL) can be carried out as follows. The support foot (100) is positioned by the support leg (SL) so that the shaft bearing is located between the mounting openings (413). The mounting shaft (440) is then passed through the mounting openings (413) and the shaft bearing. The cotter pins (442) are then inserted into the shaft locking holes (441) at both ends of the mounting shaft (440). As a result, the support foot (100) and thus the swing unit (400) are pivotably fixed to the support leg (SL).

[0076] In an embodiment of the invention, the support foot (100) comprises a rolling plate (420) having a bending point (423) which positions a part of the rolling plate (420) that is situated between the side walls (410) so as to be located inside the side walls (410). The bending point (423) is a bend from the convex edges of the side walls (410) towards a part that is situated between the side walls (410). In this embodiment of the invention, the side sections of the rolling plate (420) that are situated on the convex edges of the side walls (410) form a rolling strip (424). The rolling strip (424) is suitable for rolling on the rolling support (320). With this embodiment, a part of the rolling plate (420) that is situated between the side walls (410), i.e. a part of the rolling plate (420) that is located outside the rolling strip (424), is taken into the side walls (410). This creates space for structures on the inner surface of the base plate (200), for example a base reinforcement rib (230). During the rolling movement of the swing unit (400), the rolling plate (420) is prevented from hitting and rubbing against the structures on the inner surface of the base plate (200).

[0077] In an embodiment of the invention, the support foot (100) comprises a V-shaped guide opening (310).

[0078] In an embodiment of the invention, the support foot (100) comprises a wall reinforcement rib (415) disposed in each of the side walls (410). In a variant of this embodiment of the invention, the support foot (100) comprises a T-shaped wall reinforcement rib (415) in each of the side walls (410) that is connected to the rolling plate (420) at least at two points, and that is located on each side of the mounting opening (413). One of the most important objects of the invention is to provide a support foot (100) that is as light as possible. The wall reinforcement ribs (415) prevent the side wall (410) from bending and / or buckling due to vertical forces. With the wall reinforcement ribs (415), the resistance of the side walls (410) (and thus of the swing unit (400) and the support foot (100)) against vertical loads and lateral loads is increased.

[0079] In an embodiment of the invention, the support foot (100) comprises at least one base reinforcement rib (230) disposed in the base plate (200). The base reinforcement rib (230) prevents the base plate (200), which rests on an unstable ground, from bending, and ensures that the flat plate form is maintained.

[0080] In an embodiment of the invention, the support foot (100) comprises a hemmed edge (330) disposed on at least one edge of the guide wall (300). The hemmed edge (330) significantly increases the strength of the guide wall (300), especially its resistance against lateral forces. In particular, with the guide wall (300) having a convex form at its open edge and including a hemmed edge (330) on the convex edge, both lightness and resistance against lateral forces are achieved.
