Abstract

A self-locking hook for supporting a load on a substantially horizontal surface is disclosed. The hook has a relatively rigid C-shaped body which includes a surface defining an opening for accommodating a substantially horizontal component and a support having a load bearing or attachment point. The surface of the opening includes a first contact area and a second contact area. The load bearing or attachment point is attached to the body relative to the opening such that application of a load at the load bearing point while the first contact area is contacting a component rotates the body about the first contact area until the second contact area abuts the component. This self-locking feature allows the hook to be used effectively on both component surfaces which are slightly angled or sloped and with loads which are not perpendicular to the component surface.

Description

TECHNICAL FIELD OF THE INVENTION

The present device relates to hooks. Particularly, the present device relates to hooks for supporting a hanging load from a horizontal member.

BACKGROUND OF THE INVENTION

Hooks for supporting a hanging load from a substantially horizontal surface have been known and used for a very long time. The J-hook is a common design, often having an eyelet in one end for securing a line tied to some object to be supported. Unfortunately, the J-hook could be easily unseated from an accidental impact or quick loss of tension. C-shaped and S-shaped hooks provide slightly better security from such detachment, and O-rings, D-rings and carbiners even more protection by surrounding the horizontal surface completely when connected.
However, each of these designs fails to provide two important features needed for supporting certain loads. First, they are ineffective on non-horizontal surfaces. Even the slightest angle can create problems for these connection devices when a load is applied. The connectors will typically slide along the surface until they either are physically impeded, reach a level (i.e., horizontal) surface, or reach the lowest point of the surface.
Second, the devices are ineffective at resisting a force having a horizontal component. That is, even when secured to a perfectly horizontal surface, they will slide along that surface if subjected to a horizontal force. Much like the first problem, these devices will continue to traverse the surface unless and until they are physically impeded or the force is sufficiently abated.
The present invention overcomes these and many other disadvantages of previous devices. Disclosed is a self-locking hook which is decorative, yet functional; versatile as a support for any number of commercial, industrial, and household purposes; and is easy and relatively inexpensive to manufacture.

SUMMARY OF THE INVENTION

There is disclosed herein an improved hook for suspending a load from a substantially horizontal component which avoids the disadvantages of prior devices while affording additional structural and operating advantages.
In a first embodiment the self-locking hook comprises a rigid body having a surface defining an opening for accommodating a substantially horizontal component, the surface comprising a first contact area and a second contact area, and a support comprising a load bearing point. The load bearing or attachment point is attached to the body relative to the opening such that application of a load at the load bearing point while the first contact area is contacting a component rotates the body about the first contact area until the second contact area abuts the component.
In a particular embodiment, the hook is provided in a shower assembly for attaching to a shower head pipe. A shower unit may be attached to the attachment point of the hook such that it causes the body of the hook to bind the shower head pipe between the first surface and the second surface of the body.
These and other aspects of the invention may be understood more readily from the following description and the appended drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail a preferred embodiment of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to embodiments illustrated.
Referring to FIGS. 1-7, there is illustrated a self-locking hook, generally designated by the numeral 10. The hook 10 has a body 12 defining an opening 14 therein for fitting around a substantially horizontal component 30. The opening 14 is created by a first surface 16 of the body defining a first span of the opening 17 and a second surface 18 of the body, directly opposite the first surface 16, defining a second span of the opening 19. A support 20 is integral to the body 12 and comprises an attachment point 22 for connecting a hanging load.
As illustrated in FIG. 1, the support 20 is positioned on the body 12 relative to the opening 14 such that application of a force (F) at the attachment point 22 causes the body 12 of hook 10 to bind the component 30 between the first surface 16 and the second surface 18—the hanging load creates a force in a direction primarily perpendicular to a surface of the component 30 which is assumed to be oriented horizontally. In a preferred embodiment, as shown, the surfaces 16, 18 are rounded and comprised of a material different from that of the body 12. Preferably, the material used on the surfaces is both resilient and of a high coefficient of friction with respect to the surface of the component 30. This material may cover the entire body surface or any smaller portion thereof, including covering just the contact area of each surface. The high coefficient of friction material provides a better grip of the component surface to prevent slippage when, e.g., the component is not perfectly horizontal (i.e., sloped) or the load is not perpendicular to the surface of the component.
The opening 14 is shown in FIGS. 1 and 2 to be defined by a C-shaped inner surface of the body 12. This type of opening 14 allows the hook 10 to be readily attached to and detached from any suitable component, such as a shower head pipe, as shown in FIGS. 4-7. The surface of the opening 14 should surround the component 30 sufficiently to prevent any accidental detachment if impacted. In certain embodiments (not shown) it may be desirable to provide an opening which is closed—i.e., like an O-ring—or closable—i.e., open with a movable latching mechanism. While the closable design would function much like the C-shaped design, the closed configuration would require slipping the hook over an end of the component for attachment. Those skilled in the art would certainly understand from the foregoing description, and without more, how to sufficiently fashion either type of opening.
Similarly, with reference to FIGS. 1 and 2, the support 20 has a defined opening which functions as the attachment point 22 for a hanging load. The attachment point 22 is open at one end to allow the load to be readily attached to and detached from the support 20. However, the attachment point 22 may be closed (FIG. 2) with a permanently affixed frame or the like. The frame 42, as shown in FIG. 4, could allow for the addition of different fixtures, such as, e.g., shelves, hooks, or holders of some kind.
The greater the amount of weight (i.e., load) affixed to the attachment point 22, the greater the force (F) acting to rotate the hook 10 about the first surface 16 (i.e., torque) until the second surface 18 travels a small angle before contacting the underside of component 30. By offsetting the attachment point 22 from the contact area of the first surface 16—i.e., placing it off-center—the downward pull of force (F) seeks to center below the point of rotation, thereby forcing the contact area of the second surface 18 into abutting engagement with the component 30. This rotating action binds the component 30 between the first surface 16 and the second surface 18 of the hook 10.
In the embodiment of FIG. 1, the opening 14 is defined by a non-planar surface. By skewing or curving the surface slightly in a direction away from the attachment point 22 of the support 20, the second surface 18 abuts the component 30 after a lesser angle of travel than if the surface were planar. This feature helps create a more effective binding of the component 30.
In a preferred embodiment shown in FIGS. 4-7, the hook 10 is used to support a shower unit 40 having a wire frame 42 and at least one shelf 44, preferably two or three shelves, for holding shower accessories such as soap, shampoo, sponge, razor, and the like. The frame 42 attaches directly and permanently to the attachment point 22 of support 20. The shelves 44 may be movable on and/or detachable from the frame 42. The hook 10 may be attached via opening 14 about the shower head pipe, as shown in FIG. 7. Where the opening is closed as previously discussed, the shower head would require removal in order to slide the hook 10 onto the pipe end and up to the horizontal portion of the pipe. The weight of the shower unit 40 will cause the rotation of the hook 10 about the first surface 16, thereby binding the shower head pipe between the first surface 16 and second surface 18 of the body 12. Any added weight from the storage of previously mentioned shower items on the unit shelves 44 increases the force (F) and tightens the bind on the shower pipe.
The disclosed hook 10 may also be used to support flower pots, animal feeders, displays, pictures, signs, equipment, clothing, shelving, other supports, and a number of other items far too numerous to mention in this application for patent. Further, the size of the disclosed hook 10 can be determined by its intended use, including expected maximum load and size of the horizontal component to which it is to be secured.
The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only and not as a limitation. While particular embodiments have been shown and described, it will be apparent to those skilled in the art that changes and modifications may be made without departing from the broader aspects of applicants' contribution. The actual scope of the protection sought is intended to be defined in the following claims when viewed in their proper perspective based on the prior art.
