Description

Technical Field

[0001] The present invention relates to a device for holding, lifting and / or carrying / transporting loads, the device being made of a metallic material, particularly steel, and comprising: an opening for introducing a load fixing element, particularly a rope or loop; and a closure device fixed to the device in a swingable manner, wherein the opening can be closed by means of the closure device, the closure device having a locking / safety element by means of the locking element to keep the closure device in a closed position. Background Technology

[0002] Load-bearing devices are widely known in daily life. Therefore, lifting hooks are frequently used at the ends of lifting ropes, where loads are suspended, thus enabling the holding, lifting, and / or bearing of loads. To secure the load carried by the lifting hook, a so-called hook locking device is known. The hook locking device is used in lifting technology to secure the load suspended on the load hook.

[0003] According to DE 10 2018 116 021 B3, for example, a hook locking device for locking a lifting hook is known. This hook locking device includes at least: a locking member; a drive unit operatively connected to the locking member; and a retaining ring for securing the locking member to the lifting hook. The hook locking device is characterized in that it includes at least one device for querying the end position, configured to determine the end position of the locking member relative to the hook opening of the lifting hook. The device for querying the end position includes a locking plate, and includes at least one sensor to determine the distance between the retaining ring and the device for querying the end position, i.e., the distance between the retaining ring and the locking plate. The lifting hook locking device includes a locking member that is pivotally arranged on the lifting hook. The locking member can be moved towards the hook tip by means of a linear actuator, thereby locking the load and allowing it to move away from the hook tip, thus providing an opening for securing the load.

[0004] Another independently functioning locking element is known from DE 41 18 945 A1. This document also discloses a lifting hook locking device in which a central element, pivotally arranged on the lifting hook, is preloaded on the hook by means of an elastic element toward the tip of the lifting hook. The sides of the metal element are formed of a rubber-elastic material, thereby providing a spring force in the closed direction to position the metal element, and allowing the metal element to move against the force of the rubber-elastic material to, for example, introduce a rope into the lifting hook.

[0005] Furthermore, DD 10801 A1 can be cited as an example, which discloses a lifting hook locking device in which a spring-preloaded wing element can close an opening in the lifting hook. For this purpose, the spring-preloaded closing element with wing is preloaded in such a way that the wing of the locking member abuts against the tip of the lifting hook. To introduce a load or load-bearing element, the wing of the locking member can swing against the spring force, wherein the wing then returns to abut against the tip of the lifting hook due to the spring force.

[0006] The principle of locking mechanisms for lifting hooks has been proven. Besides locking the load, the ease of operation of the locking mechanism plays a crucial role in using load-bearing equipment. Especially under extreme weather conditions, such as pollution and / or rainfall, it is essential to ensure the high reliability and smooth operation of the locking mechanism at all times. This invention is proposed based on this principle. Summary of the Invention

[0007] The object of this invention is to provide an improved load-bearing device for holding, lifting, and / or bearing loads. In particular, the object of this invention is to provide a load-bearing device that can securely, reliably, and smoothly ensure the detachment of the load-bearing device from the load or the load-bearing component itself.

[0008] The object of the invention is achieved by independent claim 1. Advantageous designs can be derived from the specification, claims, and drawings. However, it should be noted that the examples shown in the specification and drawings should be understood as not limiting, and rather, any possible variations of the shown examples and claims are possible.

[0009] The object of the present invention is achieved by providing a device for holding, lifting, and / or bearing a load, the device being made of a metallic material, particularly steel, and comprising: an opening for introducing a load fixing element, particularly a rope and / or a loop; and a closing device fixed to the device in a swingable manner, wherein the opening can be closed by means of the closing device, the closing device having a locking member by means of which the closing device can be held in a closed position, wherein the closing device is formed by a locking mechanism including a locking tongue / ratchet and at least one locking pawl / pawl. The structure of the load-bearing device according to the present invention now achieves the following feasible solution: the load-bearing device can be closed easily and reliably at the same time. In particular, by using the locking mechanism, on the one hand, reliable holding of the load can be ensured, and on the other hand, the ease of operation of the device is improved.

[0010] Here, a locking mechanism comprising a latch and at least one locking claw is used, providing easy engagement when introducing load-bearing components, such as ropes or loops, into the equipment. The locking mechanism includes a latch that is held in the equipment, particularly between two receiving portions made of metal, in a spring-preloaded / spring-loaded manner toward its open position. Thus, in the unoperated state, the latch protrudes from the equipment or along the open direction, allowing ropes or loops to be introduced into it. To lock the mechanism, the latch then moves against the spring force toward the equipment, such that the locking claw can engage with it. For this purpose, the locking claw rests against the latch under spring load and slides along it until it reaches a locked position on the latch, and the latch and locking claw lock together. At this point, the load arm of the latch closes the area for the rope or loop to enter, thus reliably holding the rope or loop as a load-bearing component within the equipment. The pawl is preloaded by a spring in the direction it faces the bolt, which ensures that it continuously rests against the bolt or that the pawl locks into the bolt.

[0011] Here, the bolt and at least one locking claw form a locking mechanism. Depending on the implementation of the locking mechanism, it can operate using a double-locking bolt, thus having two locking positions on the bolt. Furthermore, it is possible to operate using more than one locking claw, where the locking claw position can be locked, for example, by a second locking claw. In this case, the second locking claw can be referred to as a locking lever or a locking rod.

[0012] Devices used for holding, lifting, and / or carrying loads can serve as alternatives to lifting hooks or safety hooks. Such devices are suitable for, for example, any place where it is necessary to lock personnel or loads and / or where personnel or loads should be lifted and / or carried. Here, the locking mechanism within the device forms a locking element that ensures reliable locking and thus reliable holding of the load and / or personnel through the interaction of the locking claws and the locking tongue.

[0013] The device is preferably made of a metallic material, particularly steel or aluminum, and preferably has two metal plates oriented opposite to each other, and preferably parallel to each other. A locking mechanism is rotatably arranged between the metal bodies, i.e., the locking mechanism is freely movable, and the latch extends into a receiving portion or recess of the plate, thereby ensuring interaction with the load-bearing component, such as a rope. Thus, the recess or opening for introducing the load-bearing component is at least partially closed by the latch, and after being locked into the locking claw, the latch completely closes the opening or recess or receiving port, so that the rope can no longer disengage from the latch. Therefore, the latch forms a closing device for the opening for introducing the load-bearing component, such as a metal rope or chain link. In any case, a locking element can be provided by using the locking mechanism, by which the device can achieve reliable and smooth operation of the components for lifting, carrying, or conveying loads.

[0014] In one design variation of the invention, the locking mechanism is held within the metal housing. In another embodiment, the housing may be formed of two parallel, opposing plates. In this case, the plates may be spaced apart, for example, threaded together by sleeves, thereby reliably supporting the locking mechanism within the metal plates. However, it is also conceivable that the metal housing may be formed, for example, of a U-shaped bent sheet, thereby providing at least partial and complete protection for the locking mechanism. It is also conceivable that the housing is completely enclosed, with only the receiving port for introducing the fastener and for interacting with the locking mechanism being open. The housing can be formed according to the usage and environmental conditions. In areas with high levels of pollution, an enclosed housing may be advantageous, while in areas where lightweight is advantageous, operation can be achieved using only two metal plates supporting the locking mechanism.

[0015] In another design variation, it is advantageous to include a release / trigger that allows the pawl to be manually disengaged from the latch. In its simplest form, the release can be an opening in the housing, allowing the pawl to be manually operated and thus removed from its engagement area with the latch. Advantageously, a pin can also be fixed to the pawl, allowing it to be manually gripped and moved at intervals. Furthermore, by way of example, if an opening is formed in the housing through which the pin can be operated from outside the housing, the pin can be easily gripped and the pawl moved. Of course, other solutions for operating the pawl are also conceivable, such as a belt, hook, or chain, which also functions as a release. However, the release can also include, for example, other levers arranged in the device that are also manually operated, thus allowing the pawl to move indirectly. Another advantageous design variation of the invention can be achieved if the release is electrically operated. If the release is electrically actuated, it can be remotely operated, thereby enabling other convenient applications for the device. For example, loads can be unloaded or loaded without additional assistance or manual operation, thus making the operation of the equipment significantly easier. An electric drive unit, such as an electric motor, can be arranged within the equipment itself, acting on the locking claws via a transmission mechanism or directly, thereby electrically unlocking the locking mechanism.

[0016] If the device has a closing aid that allows for the electric closing of the locking mechanism, it further facilitates the operation of the device. The closing aid acts on the latch and can move the latch into the locked position, i.e., the engagement position with the pawl, when the latch is not fully closed. In this case, the closing aid can, for example, engage with the latch and move the latch in the closing direction. This is particularly advantageous when operating the device remotely or from a remote control position, if it is necessary to ensure that the locking mechanism is in the locked position. Therefore, the closing aid is an advantageous design that particularly ensures reliable locking of the locking mechanism.

[0017] If the equipment has additional receiving ports, allowing additional fasteners to be inserted, its applications can be expanded. In this case, for example, a receiving port can be formed in the housing, allowing additional ropes, such as lifting ropes, to be inseparably connected to the equipment. The equipment can be used, for example, as a lifting hook. However, furthermore, when the equipment is used as a safety hook and, for example, for personnel climbing or locking, the receiving port can also be used to receive safety ropes. The applications are diverse, and the additional receiving ports allow the equipment to be used on both sides.

[0018] If additional locking mechanisms are incorporated into other receiving ports, such as by providing locking mechanisms at two opposing ends of the housing, the device can be applied to other fields of use. Therefore, customized solutions can be provided depending on the technical field and intended use of the device. Advantageously, modifications or combinations of the device can also be provided, for example, using an electrically driven mechanism for unlocking on one side, while manually opening and thus manually manipulating the locking claws in another locking mechanism. In any case, the use of locking mechanisms in the device provides reliable and smoothly operating components for locking, lifting, holding, and / or bearing loads. Attached Figure Description

[0019] The invention will now be described in detail with reference to the accompanying drawings. However, the following principle applies: the embodiments do not limit the invention, but merely illustrate an advantageous design. The features shown may be implemented individually or in combination with other features of the specification and the claims.

[0020] The diagram shows:

[0021] Figure 1 A view is shown of a device for holding, lifting, and bearing a load, which includes a locking mechanism and a housing, wherein the device is shown in partial perspective.

[0022] Figure 2 Showing according to Figure 1 A three-dimensional view of the device designed according to the present invention in a closed state. Detailed Implementation

[0023] exist Figure 1 The diagram shows a view of device 1 on one side of housing 2. A locking mechanism 3 is arranged inside housing 2, comprising a latch 4 and a pawl 5. Locking mechanism 3 is pivotally supported in device 1 via shafts 6 and 7. Additionally, housing 2 has a receiving port 8 extending through the entire housing 2. In this embodiment, housing 2 is formed of metal plates 9 and 10. The plates 9 and 10 are connected to each other, for example, via threaded connections 11, 12, 13, and 14.

[0024] The locking mechanism 3 is shown in the locked position, wherein the bolt 4 is locked in place by means of the pawl 5. Figure 1 In the closed position shown, for example, the rope 15 is held in the device 1 by means of the locking tongue 4. Here, the load arm 16 of the locking tongue 4 closes the entry area 17 of the device 1, so that the rope 15 can be reliably held by means of the device 1. In order to reliably lock the locking tongue 4, the locking claw 5 engages on the locking surface 18 of the locking tongue 4, thereby ensuring that the rope 15 is reliably locked by means of the device 1.

[0025] In order to release the rope 15, the locking pawl 5 must now be removed from the engagement area with the latch 4. For this purpose, the locking pawl 5 moves in the direction of arrow P. To manually operate the locking pawl 5, a pin 19 is fixed to it, and the pin can be gripped from the outside and moved through the forming part 20. The movement of the locking pawl 5 in the direction of arrow P now causes the latch 4 to disengage and move in the opening direction in the direction of arrow P2. To move the latch 4, a spring 21, such as a helical torsion spring 21, is fixed to the latch, which applies a spring preload to the latch 4 in the direction of arrow P2, i.e., counterclockwise in this embodiment. Therefore, after the locking pawl 5 releases the latch, the latch 4 moves in the direction of arrow P2, thereby disengaging the rope 15. The locking pawl 5 is again preloaded by the spring in the direction of arrow P3, so that after the locking mechanism is opened by manual operation of the locking pawl 5, the locking pawl 5 returns to its original position towards the latch. Then, the locking claw 5 rests against the outer surface 22 of the latch 4 in a preloaded manner by the spring, so that after the opened latch 4 moves in the closing direction, the locking claw can engage with the locking surface 18 again. Therefore, simple closing of the locking mechanism can be achieved by, for example, introducing a rope into the open inlet 23 of the latch 4, and moving the latch in the closing direction by means of the rope. If the latch 4 has reached the desired position... Figure 1 When the closed position is shown, the latch 5 engages with the locking surface of the latch 4 and locks the rope 15.

[0026] In this embodiment, the housing 2 has an additional receiving port 8, which is suitable for, for example, a safety rope or lifting rope, so that the device 1 can be secured to the rope or other fastener, such as a rope or chain.

[0027] exist Figure 2 The image shows a three-dimensional view of device 1. It can be seen that the housing 2 is made of two spaced-apart pieces, particularly plates, wherein plates 9 and 10 can also be made of aluminum, for example. Plates 9 and 10 are held apart from each other and assembled together by means of bolts or sleeves. However, bolts 11, 12, 13, and 14 can also be rivets, depending on the type of load that the device is to bear or support. Figure 2 The closed position is also shown, in which the locking tongue 4 is located when the fastener 15 is received in the device 1. Figure 2 The diagram shows an open housing 2; it is also conceivable that the housing is integrally formed and, for example, from a U-shaped or U-shaped sheet. In any case, the locking mechanism can be unlocked and the fastener 15 released by manually operating the pin 19. Thus, a reliable device 1 that can be easily operated is provided.
