Description:
A CARRIAGE SYSTEM

Field of the Invention

The present invention relates to a carriage system which is suitable for use in air vehicles such as aircrafts, and which is capable of safely carrying a load by being attached thereto. Background of the Invention

The delicate loads such as bombs, weapons may need to be carried from one place to another by air vehicles such as an aircraft. Therefore, the air vehicles that are used especially in defence industry have various carriage systems for attachment of said loads to them.

An exemplary bomb release mechanism for these carriage systems is disclosed in patent document no. US 8127655B1 . Said mechanism comprises hooks for engaging a store; a primary part for locking one of the hooks in its closed position; a secondary part which can slide on the primary part and locks the primary part; a fastener with a guide in which the end of the secondary part that is far from the end where it contacts the primary part moves; and an actuator for moving said hooks. When the pressure on the primary part and the hook disappears, the store is released. However, the mechanism disclosed in this document is not capable of preventing unintentional self-opening of the hook, and thus it cannot provide a safe carriage system.

Brief Description of the Invention

With the present invention, there is provided a carriage system which is suitable for use in an air vehicle, and which is capable of safely carrying at least a load by being attached thereto. Said carriage system comprises at least one retaining member which is suitable for attaching at least a load thereto, and which can move between an open position and a closed position; at least one moving element for moving said retaining member between the open position and the closed position by means of at least one power source; at least a first spring which is connected at least on one side to the retaining member and at least on the other side to the carriage system, and which serves to keep the retaining member in the open position; at least one locking element which can make rotational movement around an axis passing through its center, which locks the retaining member in its closed position by contacting the retaining member at least on its one end in a position where it is rotated, and which is connected at least on the other end to at least a second spring that applies a force in reverse direction to the force applied on the retaining member by the first spring; and at least one guide member which has at least one slot in which at least one end of the retaining member can move linearly, and which is in connection with the locking element.

The carriage system developed according to the present invention provides a safe carriage of the loads by being attaching thereto, while enabling the load to be released actively from the carriage system by allowing manual intervention in case of any lock of the carriage system due to the reasons such as bad weather conditions or in case of cancellation of any mission.

It may be necessary to attach explosives such as bombs, weapons and similar loads to air vehicles so as to carry them from one place to another. Since said loads are delicate and pose a danger on the environment, it must be ensured that they are safely carried during flight. However, a carriage system to which the loads are attached may get locked in particularly due to severe weather conditions, and thus it may not be possible to release the loads from the system when desired. Therefore, with the present invention, there is provided a carriage system which allows for manual control to release the loads under bad weather conditions or in case of cancellation of a mission, while providing a safe carriage of the loads.

The carriage system (S) developed according to the present invention, which allows for attaching at least a load thereto and carrying the load safely, is suitable for use in an air vehicle, the system comprising at least one retaining member (1 ) preferably in form of a hook which is suitable for attaching at least a load thereto, and which is movable between an open position (the position in which the load is not attached) and a closed position (the position in which the load is attached); at least one moving element (2), preferably a pneumatic piston, which can move said retaining member (1 ) between the open position and the closed position by means of at least one power source (e.g. high pressure gas); at least a first spring (Y1 ) which is connected at least on one side to the retaining member (1 ) and at least on the other side to the carriage system (S), and which serves to keep the retaining member (1 ) in the open position; at least one locking element (3) which can make rotational movement around an axis passing through its center, which locks the retaining member (1 ) in its closed position by contacting the retaining member (1 ) at least on its one end in a position where it is rotated, and which is connected at least on the other end to at least a second spring (Y2) that applies a force in reverse direction to the force applied on the retaining member (1 ) by the first spring (Y1 ); and at least one guide member (4) which has at least one slot (4a) in which at least one end of the retaining member (1 ) can move linearly, and which is in connection, at least on the other portion thereof positioned so as to be close to preferably the second spring (Y2), with the locking element (3).

In an exemplary embodiment of the invention, the carriage system (S) is arranged such that the retaining member (1 ) thereof is attached to at least one extension of the load. When the retaining member (1 ), which is initially in an open position, is brought to a proper position for attachment to the load, the load rests on the retaining member (1 ) so that member (1 ) is brought to a closed position and the load is attached to the air vehicle. Since the first spring (Y1 ) and the second spring (Y2) apply force in reverse direction to each other, it is ensured that the retaining member (1 ) in the closed position as well as the locking member (3) which is in contact with it are kept locked. Thus, unintentional release of the load from the carriage system (S) due to vibrations is prevented. When it is desired to remove the load from the carriage system (S), the moving element (2) actuated by the power source causes rotation of the locking element (3) around an axis passing through its center. The locking element (3) releases the retaining member (1 ) by this rotational movement. On the other hand, when a problem arises in operation of the carriage system (S) due to environmental conditions such as frost or pollution or in case of cancellation of a mission, the retaining member (1 ) is able to be brought to an open position manually so as to release the load. For this purpose, the retaining member (1 ) is enabled to move by moving the end of the retaining member (1 ) that is placed in the slot (4a). Therefore, the retaining element is brought to the open position and kept in this position by the help of the first spring (Y1 ).

The carriage system (S) of the present invention comprises at least one stopper (S1 ) which is detachable from the carriage system (S), which contacts the locking element (3) preferably on its portion that is close to the end connected to the second spring (Y2), and which applies a force on the locking element (3) so as to bring the retaining member (1 ) to a closed position, in order to prevent the locking element (3), which is in contact with the retaining member in its closed position where the retaining member (1 ) is attached to the load, from releasing the retaining member (1 ). The stopper (S1 ) ensures that the position, where the locking element (3) is in contact with the retaining member (1 ), is maintained by contacting the locking element (3) after the retaining member (1 ) is attached to the load.

In a preferred embodiment of the invention, the axis around which the retaining member (1 ) rotates and the axis around which the locking element (3) rotates are on the same horizontal plane (in alignment), and said horizontal plane is parallel to the ground of the air vehicle. By virtue of the fact that said parts are arranged on the same plane on the carriage system (S), the carriage system (S) is used efficiently so as to make room for the power source. Thus, a lightweight and economical carriage system (S) is achieved. In an alternative embodiment of the invention, the surface of the retaining member (1 ) contacted by the locking element (3) and the surface of the locking element (3) contacting the surface of the retaining member (1 ) are such surfaces that are compatible with each other, preferably in a cylindrical form. In this manner, while the locking element (3) is rotating by the actuation of the moving element (2), the locking element (3) contacts the retaining member (1 ), and said surfaces slide on each other due to the cylindrical structure of the contacting surfaces. Thus, both the locking process is performed in a smooth and uninterrupted manner, and also the retaining member (1 ) can be easily moved within the slot (4a) when the mechanism encounters an unfavorable situation such as frost. In this manner, the load is disconnected from the carriage system (S) without posing any danger.

In another preferred embodiment of the invention, the carriage system (S) comprises two retaining members (1 ), two locking elements (3), two guide members (4), two first springs (Y1 ) connected with the retaining members (1 ) and two second springs (Y2) connected with the locking elements (3), which are all arranged so as to be symmetrical with respect to an axis passing through the moving element (2). In an embodiment, to prevent rotation of the retaining members (1 ) due to the moments that may occur on the moving element (2) during movement of the retaining members (1 ), the carriage system (S) comprises at least one movement blocking member (not shown in the figures) having at least one housing in which the moving element (2) is positioned. Thanks to the movement blocking member, the retaining members (1 ) are activated, while the moving element (2) is prevented from rotating on its axis due to the moment occurring on the moving element (2).

In another preferred embodiment of the invention, the carriage system (S) comprises at least a first part (5), which is contacted by the moving element (2) as the moving element (2) moves, which is preferably connected to an air vehicle from a point passing through its center, and which can make rotational movement around this point. In this embodiment, the carriage system (S) comprises at least one cam part (6) which contacts the first part (5), preferably on its bottom part that is close to the ground of the air vehicle. The cam part (6) is brought, in the closed position of the retaining member (1 ), to an active state in which it is perpendicular to the ground of the carriage system (S) so that the retaining member (1 ) is prevented from being brought to the open position again. The cam part (6) is in connection with at least a third spring (Y3) preferably on its other end that is far from the end with which it contacts the first part (5). The third spring (Y3) applies a force on the cam part (6) such that it remains in its closed position (in other words, in the position where the retaining member (1 ) is in an open position). In another alternative embodiment, as illustrated in Figure 1 , of the invention, the carriage system (S) comprises at least one safety lock (S2), which is contacted by the cam part (6) when the retaining member (1 ) is in its closed position, to prevent intentional or unintentional release of the load after the air vehicle is loaded. The safety lock (S2) is detached from the carriage system (S) before the flight, and thus the position of the cam part (6) can be changed. The third spring (Y3) prevents the cam part (6) from being brought back to the position securing the carriage system (S) (in other words, to the position where the retaining member (1 ) is closed) after the safety lock (S2) is removed.

In an embodiment of the invention where the first part (5) is comprised, the carriage system (S) further comprises at least a second part (7), which is connected at least on one end to the first part (5) and at least on the other end to the locking element (3), and which enables the locking element (3) to rotate by rotational movement of the first part (5) and thus leads the retaining member (1 ) to be brought to an open position. The carriage system (S) developed with the present invention provides a safe carriage of the loads by being attaching thereto, while enabling the load to be released actively from the carriage system by allowing manual intervention in case of any lock of the carriage system (S) due to the reasons such as bad weather conditions or in case of cancellation of any mission. Therefore, there is provided a carriage system (S) which is safer when compared to the carriage systems intended for carrying delicate loads that are known in the art.
