Description
UNIVERSAL HOLDING DEVICE
FIELD OF THE INVENTION
The present invention relates, generally, to holding devices. More specifically, the invention relates to holding devices for handling, transporting, raising and lowering of containers such as compressed gas cylinders, open drums and related objects.
BACKGROUND OF THE INVENTION
In the industrial and mechanical industry where compressed gas cylinders, open drums and related objects are used there are few methods to safely handle these objects, in particular the raising and lowering of objects to and from different heights of a work area. Many methods used today are cumbersome and are time consuming.
For example, it is common practice to lower compressed gas cylinders from one level of a job site to another level by means of large bulky cage type carriers, complicated sling arrangements or strapping the cylinders to other secure items such as a cart or pallet.
Unavoidably, physical manual labour is required throughout the process. Tools available for this type of application are inefficient because of their size, cost and time involved to use them properly. They have a limited practical use and as a result these cylinders are often handled manually and/or unsafely (such as tying a rope around them) resulting in possible damage to equipment, property and personal injury.
It is also a common practice to move compressed cylinders along the same level or plane by means of tilting and roiling the cylinder. This is very difficult when encountering uneven terrain.
There is a need in today's society for universal type holding devices with simple design that facilitate a fast and convenient way to safely secure objects during lifting and placement within the work area without any additional tools. One type of device may comprise a collar and pivotally mounted gripping members that could easily be slipped onto or engaged with an object. The weight of an object enables a frictional gripping force via the pivotally mounted gripping members and as a result, the frictional gripping force that is applied to the object increases as the weight of an object increases. The collar and grips may be slid over an object, which will enable the object to be.picked up by personnel or machine with very little effort or time consumed. Handles may be incorporated into the device that facilitates personnel to safely lift and carry an object or a cable, chain or rope from a machine may be attached to each grip of the collar. Such a device could facilitate the safe lifting and carrying of objects such as cylinders with much less effort and their simple design enables one person with a fast and convenient way to safely secure the cylinder for lifting and placement within the work area without any additional tools.
The prior art has attempted to address this need for simple holding devices comprising of pivotally mounted gripping members that could facilitate a fast and convenient way to safely secure objects.
For example, United Kingdom Patent Application Publication No. 2333554A
discloses a carrier device that comprises a frame, which can be placed around an object such as a cylinder. These handles may be linked to a rope or wire allowing the object to be lifted by a machine. The collars and grips are shaped in a variety of ways.
United States Patent No. 4,795,202 also discloses a lifting handle type device for pressurised gas containers which has a circular metal band that have cut outs for a receiving pivot mount that support the wedging members. The circular metal band is placed around a container when used.

As will be realized, the invention is capable of modifications in various obvious respects, all without departing from the scope and spirit of the invention. Accordingly, the description should be regarded as illustrative in nature and not as restrictive.
Several embodiments of universal holding devices comprising of pivotally mounted gripping members are described below that are designed to apply frictional gripping forces to the outside or inside of an object such as compressed gas cylinders and open drums. The use of better shaped and designed pivotally mounted gripping members facilitates such holding devices for gripping objects with in an inward gripping motion or outward gripping motion. For example, a universal holding device according to the present invention may be used to hold a compressed gas cylinder wherein the gripping force is applied to the outside of the cylinder in an inward motion (see Fig.
1). The same holding device according to the present invention wherein the device is oriented in a manner in which the pivotally mounted gripping members point downwards may be used to hold a open drum wherein the gripping force is applied to the inside of the drum in an outward motion (see Fig. 2). Accordingly, there is provided holding devices 1 for placement about the inside or outside of an object(s) comprising of at least one collar member 2 wherein said at least one collar member has two mounting portions 3 that extend from each end of said at least one collar member, at least one gripping member 4 that is pivotally mounted between two mounting portions from at least one collar member, a means for pivotally mounting said at least one gripping member 5 between two mounting portions from at least one collar member and at least one user member 6 that extends from the end of said at least one gripping member. The holding devices according to the present invention are in a closed configuration. An example of a holding device according to the present invent is illustrated in Fig. 3.
According to an aspect of the present invention the pivotally mounted gripping members 4 that are provided are shaped and designed in a manner that facilitates holding devices capable of gripping objects with in an inward gripping motion or outward gripping motion (see Fig. 3).

This boot shaped design may facilitate the present invention for being more universal towards the type and size of the object that can be carried, in addition to providing a large gripping surface/portion area resulting in a more favourable contact point with an object. The shape of the gripping members allows for a more flexible fit of the lifting unit without the need for making adjustments every time the unit is moved from one object to another without effecting the gripping action, and also allows for the lifting unit to be used on various size objects within the collar size range.
The shape and size of the gripping members may also allow the gripping members to open and close with very little effort on the operator's part, with no binding or jamming of the gripping members. This is facilitated by the edgeless design of the gripping members. The shape and design of the gripping members may allow attachments to be 20, installed on the gripping members for various functions (such as a remote "open"
attachment). Also with the shape of the gripping members the same unit may be used for both gripping the outside of a container or with the reversing of the gripping members, the inside of a container. The pivotally mounted gripping members may comprise a pivot hole 7 to be used in conjunction with a pivoting mounting means 5. It is preferable that the pivotally mounted gripping members are serrated at the gripping surface portion for increasing friction during gripping use. It is also preferable that there are multiple gripping portions on the gripping members as shown in Fig. 3. Furthermore, a rubber type coating may be employed on the gripping surface portion to provide a more favourable contact point with an object, depending on type of application.
