A USTRALIA 21/08/00 A CLAMP DARJUSZ KADL UBAJSKJ EMI CLAMP The present invention relates to improvement in devices suitable for suspending a load from an elevated structure securely, especially when the object suspended is not held stationery or is in a swanning motion.

The device is suitable for quick, easy and secure way to suspend a load from an elevated structure such as the architraves, pergolas, trees, There are several types of homeware items including furniture items that are design to be suspended.

One example is a swing for a toddler.

Such swings are provided with a frame similar to a playground swing frame but smaller in dimensions from which a swing seat is suspended. The frame is usually made from lightweight metal components. The swing frames are unsteady and cannot rigidly support the swinging or bouncing weight of an older child. The toddler swing can be used only up to 3 to 6 months and the space of a small household does not allow the metal frame to be used inside.

Another type of a child's bouncing swing is provided with a pair of hooks, which rest on the architraves, and are held in place by a spring. These hooks are not sufficiently :strong to support the weight of heavier objects, especially when the object supported is not held stationery or in a swing motion. If a child bounces on suspended hooks an injury may occur due to insufficient safety protection from each side of architraves S"where the child is suspended. When a child bounces in the swing, the hook system can disengage from architraves resulting in the swing( hooks falling to the ground.

FIG. 1. It is an object of the present invention to provide a device suitable for suspending a load from an elevated structure having a pair of opposite faces, which are secure and simple to mount to the elevated structure. The opposite faces are pair of opposite arms, which may be made from steel tubing or any suitable material such as moulded plastic. The opposite arms are formed into approximately question mark shape. The opposite arms can contact and apply transverse clamping force to the opposite faeces of the elevated structure, without any mechanical means. The opposite arms are adapted to receive the weight from suspended load.

FIG.2. When the load is suspended, the weight of the load is centralised between the two arms (main pivot and transferred into clamping force which is applied by the clamping means on the elevated structure, to hold the load securely with respect to the elevated structure. When the load is not suspended, the clamping means that are in contact with opposite sides of elevated structure will securely stay in contact.

The device of the present invention may be thought of as a clamp. It is a weight bearing apparatus designed to utilise the weight of the suspended load. It also secures itself and stabilises the load in a suspended relationship to the elevated structure.

A further object of the invention is to provide a doorway CLAMP which may be easily assembled and disassembled by the user so that it may be stored or any parts may be easily cleaned or replaced.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.A illustrates the clamp with a partial sectional view of the tube and a respective view of the present invention; FIG.2 ilusttrates the clamp side view of FIG.I with the metal ring, plastic filling for metal ring, aluminium round filling, pin bolt and eye bolt removed.

FIG.3 illustrates plan view of the clamp mounted on the

ARCHITRAVES.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIG.1 and FIG.2 is a respective view of the clamp with partial sectional view of the metal tube It can be seen that the (clamp) bearing apparatus according to this invention consists of two main arms 1 which are formed into approximately question mark shaped legs.

These two legs are pivoted together with a pin bolt 13 creating scissor action. Main pin bolt 13 is situated approximately in a middle of the main arms 1, and is held by a nut with a nylon thread FIG.2, 17. In between the main arms 1 a metal ring 2 is supporting itself on the pin bolt 13.

Inside the metal ring 2 a plastic filling 11 is held to prevent movement of metal ring 2 up and down. Inside the plastic filling an aluminium round filling (spaced) FIG.2 18 0 is placed to obtain just enough space between the two main arms 1 on the pin bolt 13 for the metal ring 2 to move with ease on the pin bolt 13. The main arms 1 are creating a pair of clamping arms that grip each side of an elevated structure or a wall and rest on the ARCHITRAVES of a doorway The pair of two curved ends of the main arms 1 are Spreferably ending with a rubber closure 14 to hold the load with the respect and protect elevated structure from damage.

The main arms 1 are held in place initially by the small tension spring 15 between the lower ends of the two legs.

This spring 15 only provides sufficient force to prevent the the main arms 1 from falling from the elevated structure (wall). The main clamping force is achieved by the use of the swing support rope 4. This rope 4 is secured by a end clip 9 and thread through a hole at the bottom of one of the main arm 1 straight legs. The rope 4 passes through an eye bolt 7 attached to the bottom of the other main arm 1 straight leg.

The eye bolt 7 is held in place with a nut FIG.2 17. The rope travels up through a metal ring 2 which is attached to the pin bolt 13 (main pivot) and between the two main arms 1 and then hangs vertically down to just below the level of the lower ends of the main arms 1. The rope 4 is terminated with an eye drops thimble 5 and provided with aluminium ferrules 6 to attach a safe load. The safe load attached is transfered through the rope 4 to main arms 1 providing a clamping force between the upper ends of the two main arms 1 The ends of the lower ends of main arms 1 have small plastic plugs 3 to cover the hole in the end of the tube. The ends of the main arms 1 of the clamp legs that clamp to elevated structure (against the wall) have rubber closure 14 fitted which can be easily removed. When the rubber closure is removed a hole 16 is provided to connect a number of accessories. To obtain a clen finish of the clamping apparatus four washers 12 are placed on the pin bolt 13, one washer FIG.2, 12 is placed on the eye bolt 7, one washer 8 before end clip 9, main arms 1 are powder coated and the ends of the rope are covered with a plastic coating.

Claims (9)

1. A clamp suspending device utilize the weight of the suspended item to secure it self and stabilize the load in a suspended relationship to the elevated structure without any part of the fasteners being included on the elevated structure.

2. The elevated structure suspending device based on two opposite arms are formed into approximately a question mark shape to converge each other on an elevated stucture under a load without any mechanical means.

3. The suspending device centralizes the weight of the load between two arms (main pivot) which transfers into clamping force to hold the load securely on an elevated structure.

4. The two arms joined parallel on the main pivot point are bent on an approximate question mark shape and meet directly in line with each other on the elevated structure.

A pair of rubber seals protect any surface from damaging any elevated structures during usage of the suspending device and the lower ends have small plastic plugs to cover the hole in the end of the tube.

6. The metal ring filled with nylon filling placed in between the two arms on the main pivot point moves freely supporting the suspended weight.

7. The safety spring protects the suspending device from falling off elevated structures when the load is not on.

8. The rope is secured through a whole at the bottom of the arm of one of the straight arms. It passed through an eyebolt attached to the bottom of the other arm up through the ring attached to the main pivot and between the two arms and then hangs vertically down to just below the level of the lower end of the arms.

9. The end of rope is terminated with an eye and provided with a carabineer to attach safe load. The safe load attached is transferred through the rope and provides a clamping force between the upper ends of the two arms.defining Dariusz Kadlubajski 27 NOVEMBER 2000
