Description
8343.1106 DESCRIPTION TRAILER COUPLING LOCKING MEMBER The present invention relates to prevention of unintentional release of the trailer coupling used for coupling the trailer to the vehicle in trailer towing vehicles.
Trailer towing vehicles are formed by connecting a trailer behind heavy commercial vehicles with the help of a part called the trailer coupling. The connection rod between the trailer and the trailer coupling is called the drawbar and the rear trailer couplings enable to tow the trailer by the help of the drawbar. Unintentional displacement of the drawbar is an undesirable situation.
The trailer couplings are automatically coupled to the trailer. When the drawbar in the trailer touches the trailer coupling, the trailer coupling locking pin is automatically closed thanks to the mechanism inside the trailer coupling and the vehicle and the trailer are locked to each other. The coupling between the vehicle and the trailer is manually released. The vehicle and trailer are disconnected by lifting the release lever provided on the side of the trailer coupling. Since the trailer coupling is released by hand force with the help of a release lever, the force required to lift the release lever must be such that the lever can be lifted by a human. The force required to lift the release lever has been standardized so that it cannot be higher than the force a human can exert. Therefore, this value is determined as a limit value for all trailer couplings.
As a result of the tests performed and the evaluations received from the users, it has been determined that the release lever of the trailer coupling may be released spontaneously under difficult road conditions due to vibration, and may cause the vehicle to detach from the trailer. This problem is more frequently encountered particularly in the rear trailer couplings with rubber dampers referred to as "comfort coupling". It is undesirable for the release lever to be released 8343.1106 spontaneously and this may lead to accidents by causing unintentional detachment of the trailer. In order to solve this issue, it is recommended to use the trailer couplings in suitable road conditions. In addition, since the release lever needs to be released by human power, the power required to release the release lever cannot be increased in order to prevent spontaneous release.
The International Patent Application no. WO2004071792, an application in the state of the art, discloses a mechanism wherein two elements lock to each other when they rest on the lever and the trailer coupling in order to prevent trailer coupling lever.
United States patent document no. US2005230935, another application in the state of the art, discloses a safety pin which prevents unintentional release of the trailer coupling.
United States patent document no. US3161422, another application in the state of the art, discloses a spring mechanism which prevents release of the trailer coupling. By means of this spring mechanism connected to a lever, unintentional release of the trailer coupling is prevented.
The objective of the present invention is to provide a locking member which prevents unintentional release of the trailer coupling.
The locking member; which is developed to fulfill the objective of the present invention, and which is defined in the first claim and the other claims dependent thereon; has one end mounted to the release lever and the other end mounted to the locking protrusion located on the other end of the trailer coupling, and prevents spontaneous release of the release lever. 8343.1106 The invention prevents unintentional release of especially the rear trailer couplings. By preventing vibration of the release lever, the locking member prevents spontaneous release thereof, and thus prevents release of the trailer coupling and unintentional detachment of the trailer from the vehicle.
In one embodiment of the invention the locking member is produced from rubber material.
In one embodiment of the invention, the locking member comprises a first end mounted to the release lever, a second end mounted to the locking protrusion, and a connector which connects the first end and the second end to each other. In this embodiment of the invention, the locking member comprises a slot which is located on the first end and fits over the release lever located on the side of the trailer coupling. The slot encompasses the release lever almost like a casing. In this embodiment of the invention, the locking member further comprises a hole, which is provided on the second end, and fits over the locking protrusion located on the side of the trailer coupling.
In one embodiment of the invention, the locking member comprises a handle which is located on the first end right above the slot and which extends on the same direction with the connector.
When the user couples the vehicle to the trailer, mounts the second end of the locking member to the locking protrusion. In this case, the hole fits over the locking protrusion extending in the horizontal plane. Then the first end held from the handle is extended towards the release lever by passing the connector preferably under the trailer coupling, and the release lever is fitted into the slot, thereby completing mounting of the locking member onto the trailer coupling. In this case, the locking member can be extended from one side of the trailer coupling to the other side thereof by being pulled under the trailer coupling since 8343.1106 it is flexible and it is mounted to the locking protrusion and the release lever provided on each side of the trailer coupling.
Mounting and removing the locking member to/from the trailer coupling is very easy and ergonomic thanks to the handle. As long as one does not hold and pull the handle, spontaneous detachment of the locking member from the release lever is not possible.
Since vibration of the release lever is prevented by means of the locking member, spontaneous release of the trailer coupling and thus unintentional detachment of the trailer from the vehicle are prevented.Since the locking member is produced from rubber material, it is very lightweight, suitable for outdoor weather conditions and easy to use.
By means of the invention, release of the trailer coupling due to spontaneous movement of the release lever, and thus detachment of the trailer from the vehicle and causing accidents are prevented.
The locking member developed to fulfill the objectives of the present invention is illustrated in the accompanying figures, in which: Figure 1 is a perspective view of the vehicle and trailer coupling.Figure 2 is a perspective view of the trailer coupling.Figure 3 is a view of the locking member.Figure 4 is a perspective view of the locking member and the trailer coupling. Figure 5 is a perspective view showing the steps of attachment of the locking member to the trailer coupling.
The components shown in the figures are given reference numbers as follows: 8343.1106 1. Trailer coupling2. Locking member3. First end4. Second end5. Connector6. Slot7. Hole8. Handle9. Locking protrusion10. Release lever11. Grip The locking member (2) is suitable for use on a trailer coupling (1) having a locking protrusion (9) and release lever (10) (Figure 1 and Figure 2); and comprises a first end (3) mounted to the release lever (10), a second end (4) mounted to the locking protrusion (9) located on the other side of the trailer coupling (1), and a connector (5) which connects the first end (3) and the second end (4) to each other.
The invention prevents unintentional release of especially the rear trailer couplings. The locking member (2), by preventing vibration of the release lever (10), prevents spontaneous release thereof, and thus release of the trailer coupling (1) and unintentional detachment of the trailer from the vehicle.
In one embodiment of the invention the locking member (2) is produced from rubber material.
In one embodiment of the invention, the locking member (2) comprises a first end (3) mounted to the release lever (10), a second end (4) mounted to the locking protrusion (9), and a connector (5) which connects the first end (3) and the second 8343.1106 end (4) to each other and which is passed under the trailer coupling (1). In this embodiment of the invention, the locking member (2) comprises a slot (6), which is located on the first end (3), and fits over the release lever (10) located on the side of the trailer coupling (1). The slot (6) extends in a direction perpendicular to the plane where the connector (5) is located. The slot (6) encompasses the release lever (10) almost like a casing.
In one embodiment of the invention, the locking member (2) comprises a hole (7), which is provided on the second end (4), and fits over the locking protrusion (9) located on the side of the trailer coupling (1). The second end (4) of the locking member (2) is mounted to the locking protrusion (9) by means of this hole (7) (Figure 3).
In one embodiment of the invention, the locking member (2) comprises a handle (8) which is located on the first end (3) right above the slot (6) and which extends on the same direction with the connector (5). In this embodiment of the invention, the locking member (2) comprises one or more grips (11) which enable the user’s hand to hold the handle (8) without slipping.
When the user connects the vehicle to the trailer, the locking member (2) is mounted to the locking protrusion (9) by means of the hole (7) provided on the second end (4). In this case, the hole (7) fits over the locking protrusion (9) extending in the horizontal plane (A). Then the first end (3) held from the handle (8) is pulled towards the release lever (10) such that the connector (5) passes under the trailer coupling (1). This process can be easily performed thanks to the flexibility of the locking member (2). Again by holding the handle (8), the slot (6) provided on the first end (3) of the locking member (2) is fitted over the release lever (10) located at the other side of the trailer coupling (1) almost like a casing, and upon fitting of the lever into the slot (6), mounting of the locking member (2) to the trailer coupling (1) is completed (B). The slot (6) encompasses the release 8343.1106 lever (10) with a shape relation. Therefore, the locking member (2) is not spontaneously released and detached from the release lever (10) of the trailer coupling (1). The user should hold the handle (8) in order to detach the locking member (2) from the trailer coupling (1) (Figure 4 and Figure 5).
The locking member (2) can be extended from one side of the trailer coupling (1) to the other side thereof by being pulled under the trailer coupling (1) since it is flexible, and it is mounted to the locking protrusion (9) and release lever (10) provided on each side of the trailer coupling (1). Mounting and removing the locking member (2) is very easy and ergonomic thanks to the handle (8). As long as one does not hold and pull the handle (8), spontaneous detachment of the locking member (2) from the release lever (10) is not possible.
By means of the locking member (2), vibration of the release lever (10) is prevented, and spontaneous release of the trailer coupling (1) and thus unintentional detachment of the trailer from the vehicle are prevented.
Since the locking member (2) is produced from rubber material, it is very lightweight, suitable for outdoor weather conditions and easy to use.
By means of the invention, release of the trailer coupling (1) due to spontaneous movement of the release lever (10), and thus detachment of the trailer from the vehicle and causing accidents are prevented.
As a result of the tests conducted, it has been determined that the locking member (2) prevents the release lever (10) from getting affected by the vibration. Since the locking member (2) is made of rubber, it is very lightweight, and can be easily and ergonomically mounted and removed by the help of the handle (8) provided thereon.
