Description:
A DEVICE FOR OPENING A LID FIELD OF THE INVENTION The present invention is particularly concerned with devices which allow hands free opening of a lid.

The invention is particularly concerned with lids of bins and seats of toilets.

BACKGROUND TO THE INVENTION In a typical situation a wheelie bin must be opened with one hand so that rubbish can be deposited therein with another. If a person is carrying rubbish in two hands then the rubbish must be put down before the lid can be opened. This problem is compounded for people who are physically challenged.

In another situation the seat of a toilet must be lifted if it is desired to move it to the upright position. This can be difficult for a person who is physically challenged and leads to another problem namely putting the toilet seat down once the toilet has been used. In a similar fashion the lid of a bin does not necessarily get closed once rubbish has been deposited in it.

It would be preferable to produce a device which would enable a lid to be lifted without the use of a persons hands.

SUMMARY OF THE INVENTION According to the present invention there is provided a device for opening a lid comprising a frame having a control lever operable by a foot and pivotable about a pivot point, a lid lever means connectable to a rear portion of a lid and extending from a rear end of the control level and a support structure removably connectable to a receptacle to which the lid is attached wherein the pivot is arranged to be connected to the support structure.

It is preferred that the device is removably attachable to a lid.

The lid lever means may comprise side levers each being connectable to a respective side of the lid.

The control lever may be connected to each one of the side levers.

The control lever may comprise side members extending from each side thereof.

Preferably the control lever is arranged to extend in front of the receptacle lid.

It is preferred that the side members extend rearwardly to respective sides of the receptacle lid.

The side members may extend approximately horizontally when the lid is in a closed position.

The side levers may extend approximately vertically when the lid is closed.

Preferably the side levers extend at a small angle with respect to vertical.

It is preferred that the side levers extend at an angle to a rear portion of a respective side member.

The side levers may be pivotally connected to the side members.

Preferably the lid lever means is pivotally connected to the lid.

The side levers may each be pivotally connected to the lid.

Figure 5 shows a front view of a device for lifting a bin lid according to a first embodiment of the invention; Figure 6 shows a side view of the embodiment shown in Figure 5; Figure 7 shows a clamping frame for the device shown in Figures 5 and 6; and Figure 8 shows a plastic pin for use with the device shown in Figures 5 and 6.

DETAILED DESCRIPTION OF DRAWINGS The device shown in Figures 1 and 2 consists of a horizontally oriented foot pedal lever 10 located at the front of a toilet 11 close to the floor with rearwardly extending horizontal elements 12 and 13. Each of these elements 12, 13 is fixed through a pivot pin 14 to a support bar 15 which extends from the base of the back of the seat 16 to the floor at a position slightly forward of the mid section of the toilet seat. As shown clearly in Figure 1 the lower end of the support element 15 is formed into horizontal feet 17. The top end of the support element is connected to the back of the toilet seat through a clamping pin 18.

A pivoting lever 19 is located on either side of the toilet and is connected between the toilet seat and a rearward end of the side element 12. At its upper end the lever 19 is pivotally connected between the back and mid section of the toilet seat through a pivot pin 20.

With the toilet seat in its lower position the lever 19 slopes at a slight angle with respect to the vertical downwardly to its pivot connection through pivot pin 21.

In operation the toilet seat 22 and toilet seat lid 23 are lifted by the person placing their foot on lever 10. Downward pressure on lever 10 pivots lever 12 about pivot pin 14 and forces the rearward end of lever 12 to move upwardly. At the same time lever 19 moves upwardly and this opens the seat 22 and lid 23. When the foot is taken off lever 10 the weight of the seat and the lid ensures that they return to the original resting

position. In this respect it should be noted that the lid and seat should be angled slightly away from a vertical position when lever 10 is fully depressed by a foot otherwise the lid 23 and seat 22 could remain at rest in a vertical position. Alternatively a strap 18 can be employed at the back of the seat 22.

To ensure that the lid and seat can be lifted together a magnetic device 24 may be located at the front of the lid and in the top surface of the adjacent seat to ensure that both lid and seat move together. A person is then still able to lift the lid against the magnetic attractive force if it is so desired.

In Figure 3 the lifting device is slightly modified so that there is a single lifting lever 30 on one side of the toilet. In this embodiment the support element 15 is replaced by a single leg element 31 which extends from pivot pin 14 to the ground. As in the first embodiment lever 12 is still able to pivot with respect to pivot point 14. Lever 13 in contrast only extends to the pivot pin 14 and is merely provided to ensure the lever 10 is properly supported and is able to pivot in a uniform manner.

In a similar fashion to the device shown in Figures 1 and 2 a clamping pin 32 may be provided at the rearward end of the toilet seat to ensure that the lid and/or seat cannot be lifted to a vertical position or beyond.

Figures 5 and 6 show a device for use with a wheelie bin. In these figures a foot lever 40 is shown at the front of the wheelie bin extending horizontally to either side thereof. Side members 41 and 42 are located on either side of the wheelie bin and extend rearwardly in a horizontal orientation when the bin lid 43 is closed.

Both side members 42 and 43 are pivotally connected to a clamping frame 44 through pivot pins 45 at a point slightly in front of the mid point of each side member 41, 42.

The clamping frame 44 consists of a rectangular shaped metal element which is designed to wrap around a

lower part of the wheelie bin 46 to form a loop. At the back of the wheelie bin 46 the ends of the loop are formed into parallel end elements 47 which may be connected together through a suitable connection means such as a nut and bolt. By drawing the two ends 47 together the loop is tightened around the periphery of the wheelie bin 46 until it is firmly connected thereto.

Because the wheelie bin increases in size from the top to the bottom it is impossible to lift the loop higher than its fixed position.

At the end of each side member 42, 43 a lifting lever 48 is connected pivotally thereto and at its upper end to the lift 43 in a similar fashion to lifting lever 30 and 19 in Figures 1 to 4.

The loop 44 is provided with side elements 48 on either side thereof which extend perpendicular to the direction of side members 41, 42. Each side element 48, 49 is provided with a suitable attachment means to allow side members 41, 42 to be pivotally attached thereto.

According to one embodiment this is achieved using a pin moulded washer. Each side member 41, 42 has a hole which enables it to be received on side elements 48, 49 so as to pivot thereon. A suitable retaining pin or nut can be used to ensure that the side elements do not fall off these side elements.

The lifting levers 47 are attached to the lid 43 using plastic pins 50 shown in Figure 8. These pins can be received in coiled lugs 51 located on either side of the lid 43 and can be inserted through a hole 52 in the top end of each lever 47 to ensure the lever is pivotal with respect thereto. The pins are inserted in to the coil lugs 51 by squeezing their ends together so they fit into the lugs. They are thus removed the same way.

The devices described above can be removably connected to a wheelie bin or toilet in contrast to existing devices. Thus when it is necessary to empty the wheelie bin the lid opening device can be removed by simply disconnecting pins 50 from lugs 51 and removing

side members 42, 43 from side elements 48, 49. The bin can then be emptied by using conventional waste removal trucks without damaging the lifting device.

In a similar fashion the device for lifting the toilet seat can be removed whenever it is desired to do so. It is also thus easy to mount both devices.
