The present invention is generally related to devices for suspending articles above ground. More particularly, the present invention relates to a device for hanging articles over a tightened horizontal wire.
In general, for hanging article over a wire which is already tightened horizontally, more robust and tricky assemblies are used, which may be very tedious and unsafe to use.
Conventionally, hooks for hanging articles up on wires are well known. Hooks are well known in the prior art for suspending articles. In some applications where the hook is subject to a component of force generally parallel to the horizontal wire there is a requirement to prevent the hook from sliding along the horizontal wire. Other products in the prior art use various complex gripping mechanisms to achieve this. These mechanisms can be expensive to produce and suffer from reliability problems due to their complexity.
For example, hooks for hanging articles or products up on wires which are subject to components of horizontal force are also well-known (e.g., Gripple C-Clip). However, these hooks and related assemblies are complex and have reliability issues, and one cannot take chances to hang or suspend articles above the ground with reliability issues in mind. Another example may include devices that grip rope or wire by means of fixed teeth, which are also well known in the marine industry. Additionally, spring retention clips are well known in the markets. Another example can be a heavy duty drop ceiling hooks, that is usually a one-piece hook, either full or partially S-shaped, with a T-shaped end parts that can be opened up and secured to metals bars in the drop ceiling grid. The articles here can be hanged on the S-shape of the hook. However, such hooks are tricky, which may be unsafe to use. The open end of the S-shape may allow a space for the articles to get unhooked and fall.
Another fallback of the conventional hangers or hooks may be their complicated design for engaging with the rope. For position adjustment along the horizontal axis, one needs to completely disengage the hook off the wire and apply the horizontal force along the horizontally tightened wire or rope or bar. To disengage the hook and apply such horizontal force, an operator might have to reach the top of the ceiling where the rope is secured in the ceiling, and manually adjust the position of the hooks on that rope. Such task can be tedious, risky and time and energy consuming.
Hence, there is a need for designing and developing a device, e.g., a cathook attachment for suspending articles of any size, shape and weight on a horizontal wire, above the ground, which is easy to use and is flexible, and is trustworthy for suspending articles.
Thus, the present invention provides a device, e.g., a cat-hook attachment for suspending articles over a horizontally tightened wire, rope, or bar, above the ground.
It is an object of the present invention to provide a device that is easy to use and is flexible.
Another object of the present invention to provide a device that is safe and trustworthy for hanging articles above the ground.
Another object of the present invention is to provide a device that may take up a desired load of an article.
It is an object of the present invention to provide a device with an improved method of preventing the device from slipping along the horizontal wire when subjected to a component of force in that direction.
Another object of the present invention is to provide a device that may be flexibly positioned horizontally along the wire while an operator being on the ground, or without the operator manually reaching around the horizontal wire, which can be secured at top of a ceiling. So, the present invention provides a device that may avoid a user to go up to a ceiling, in case the wire is secured in the ceiling, and adjust the position of the device horizontally along the wire.
To further clarify the advantages and features of the present invention, a more elaborate description of the invention will be rendered by reference to specific embodiments thereof, which is illustrated in the appended drawings.

For a better understanding of the embodiments of the machine and methods described herein, and to show more clearly how they may be carried into effect, references will now be made, by way of example, to the accompanying drawings, wherein like reference numerals represent like elements/components throughout and wherein:
This patent describes the subject matter for patenting with specificity to meet statutory requirements. However, the description itself is not intended to limit the scope of this patent. The principles described herein may be embodied in many different forms.
Illustrative embodiments of the invention now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.
The present invention provides a device, e.g., a hook attachment, for hanging articles of any shape, size and weight, over a tightened tensioned horizontal wire, where the device resists forces in both horizontal directions and resists unwanted torque that may be imposed by the applied load of the article on the device.
The device (may interchangeably referred to as “hook” from hereinafter, but is not limited to “hook”) may include at least two parts: a wire coupling part and a load bearing part. The wire coupling part is a part of the hook where the hook flexibly couples with the tightened horizontal wire, and the load bearing part is the part where an article can be hanged in the hook. The wire coupling part allows movement of the hook along the wire in both horizontal directions, and the load bearing part is designed such that it ensures that the applied load of the hanging article does not impose unwanted torque on the hook, which may further disengage the wire coupling part of the hook from the wire.
In an embodiment, the wire coupling part and the load bearing part are assembled together to form the hook attachment, where the wire coupling part couples with the wire above, and the load bearing part bears the load below. In an embodiment, the wire coupling part and the load bearing part are assembled together detachably.
In an embodiment, the load bearing part 104 includes a groove or a curved slot 112, for example, shaped like a smiley []. Any desired article, with any shape, size and weight can be hung in the groove 112. The curved groove 112 ensures that the applied load of the hanging article does not impose unwanted torque on the hook 100. The articles can be hung removably or may be fixed on the groove 112, depending on the requirements, without deviating from the meaning and scope of the present invention.
The pivotable clip 106 provided at one end of the hook 100 prevents the hook 100 from falling out of the wire and thus provides the safety of the articles from falling down, when someone tries to tamper with the hook 100. Also, the wire coupling part 102 including the clip 106 aligned with the U-shaped portion 108, resists forces in both horizontal directions, which securely positions the hook 100 over the wire and does not cause unwanted movements of the hook 100 over the wire.
Further, owing to the simple design of the hook 100, the hook 100 is securely coupled to the wire due to the downward force of the applied load of the article, which also does not cause unwanted movements of the hook 100 over the wire. If, however, the hook 100 has to be re-positioned to another position on the wire, again owing to the simple design of the hook 100, one has to simply remove the applied load of the article, which takes off the downward force of the applied load, and shift the hook 100 to the other position, without disengaging the hook 100 from the wire. Unlike conventional hooks, where one has to disengage the hook completely off the wire, and then reposition the hook on the wire. This saves a user their time and energy, and it is easy to use.
In an embodiment, the inner surface of the hook 100 is provided with a number of teeth 114 positioned to engage with the horizontal wire. The teeth 114 are arranged in such a way that they engage with a range of diameters of the horizontal wire. In the embodiment shown, the teeth 114 are arranged in opposing pairs such that the gap between them is tapered, so that the gap can accept a range of diameters of horizontal wire.
The pairs of teeth 114 may also be spaced apart such that the distance between each pair of teeth 114 is generally equal to the lay length of the wire divided by the number of strands in the outer layer. Typically, in a 7 by 7 wire construction there are six strands in the outer layer. Spacing the pairs of teeth 114 apart in this way means that the teeth 114 naturally want to grip the horizontal wire in the small depressions between each individual strand on the surface. The number, position, and taper of the teeth 114 can be varied according to the precise design and construction of the horizontal wire.
The purpose of the curved slot 112 is to prevent the suspended article imposing any unwanted torque on the hook 100 that may tend to disengage one or more pairs of teeth 114. Generally, the center of the arc in the curved slot 112 that describes the slot 112 should be at the center point of the teeth 114.
In an embodiment, the device 100 is a cat-hook.
It may be apparent to a person ordinary skilled in the art that the hook 100 may not be designed only in the way as shown in the ], but it can also have different shapes, as long as it ensures that the applied load of the hanging article does not impose unwanted torque on the hook 100. Other exemplary variations can also be included in the present invention.
It may also be apparent to a person ordinary skilled in the art that the hook 100 may be applied to hang articles over a tightened and tensioned wire, rope, bar, and the like elements, at any height, above the ground, for example around the ceiling, without deviating from the meaning and scope of the present invention.
The hook 100 can be applied in wire hanging systems, example in electrical accessories, HVAC, among other suitable applications, without deviating from the meaning and scope of the present invention.
Advantageously, the hook in the present invention is simple in design, easy to manufacture and use. The hook is flexible, also is safe and trustworthy for hanging articles above the ground. The hook attachment of the present invention may take up a desired load of an article.
Additionally, the hook attachment may be flexibly positioned horizontally along the wire while an operator being on the ground, without disengaging the hook from the wire, e.g., without the operator manually reaching around the horizontal wire, which can be secured at top of a ceiling, owing to the simple design of the hook. So, the present invention provides a hook attachment that may avoid an operator to go up to a ceiling, in case the wire is secured in the ceiling, and adjust the position of the hook attachment horizontally along the wire.
It is intended that the disclosure and examples be considered exemplary only. Though the present disclosure includes examples from electrical accessories, HVAC, the hook disclosed herein may be employed for various applications as would be appreciated by one skilled in the art. The references to devices and structures used here are intended to be applied or extended to the larger scope and should not be construed as restricting the scope and practice of the present invention.
While certain embodiments have been described, these embodiments have been presented by way of example only and are not intended to limit the scope of the present disclosure. Indeed, the novel methods, devices, and systems described herein may be embodied in a variety of other forms. Furthermore, various omissions, substitutions, and changes in the form of the methods, devices, and systems described herein may be made without departing from the spirit of the present disclosure.
