(10) FIG. 9 is an enlarged view of a middle part of the door stop as shown in FIG. 7; and

(11) FIG. 10 shows part of a second door stop formation of the present invention.

(12) Referring to FIGS. 1-9, there is shown a door stop 2 which comprises a hanger part 4 and a door stop part 6 which in use hangs from the hanger part 4.

(13) The door stop part 6 is such that it comprises a first door stop formation 8 for being positioned at a hinge side 10 of a door 12, and in a gap 14 between the door 12 and a door frame 16 for the door 12.

(14) The door stop part 6 also comprises a second door stop formation 18 for being positioned at the hinge side 10 of the door 12, and in the gap 14 between the door 12 and the door frame 16 for the door 12.

(15) The first door stop formation 8 is below the second door stop formation 18 when the door stop part 6 hangs from the hanger part 4.

(16) The first door stop formation 8 is of a first door-stopping size which stops the door 12 in a first open position at a first open angle. This first open position is shown in FIGS. 1 and 4.

(17) The second door stop formation 18 is of a second door-stopping size which stops the door 12 in a second open position at a second open angle. This second open position is shown in FIGS. 2 and 5.

(18) The first open angle is larger than the second open angle. The first open position is for use by an adult. The second open position is for use by a child. The first open position is not restricted to being for use by a adult and it may be used by, for example, a child or a household pet. Similarly, the second position is not restricted to being for use by a child and it may be used by, for example, an adult or a household pet.

(19) The first open position is such as to cause the gap to be of a first size. The second open position is such as to cause the gap to be of a second size. The gap of the first size and the gap of the second size are both such that the child cannot get their fingers trapped firstly between the door 12 and the door frame 16 at the hinge side 10 of the door 12, and secondly between the door 12 and the door frame 16 at a handle side of the door 12.

(20) FIGS. 3 and 6 show the position of the door stop 2 when the door 12 is in a closed position. It will be seen that the first door stop formation 8 and the second door stop formation 18 are not in the gap 14. Only the hanger part 4 is in the gap 14.

(21) As shown in FIG. 7, the door stop 2 is such that the second door stop formation 18 is longer than the first door stop formation 8. The second door formation 18 is in the form of a rod. The second door formation 18 is cylindrical in cross section.

(22) The first door stop formation 8 is in the form of a knob. The first door stop formation 8 has a curved outer face 20.

(23) The first door stop formation 8 tapers outwardly in a direction away from the second door stop formation 18. The first door stop formation 8 is a one-piece first door stop formation 8.

(24) The first door stop formation 8 preferably has a friction-increasing outer surface. The friction-outer surface is preferably a plurality of longitudinally extending splines. The splines are preferably such that they have peaks, and the peaks are non-pointed peaks. The non-pointed peaks increase the surface area with which the first door stop formation 8 is able to operate.

(25) The hanger part 4 is a length of flexible material. The length of flexible material is a length of cord. The first door stop formation 8 is axially in line with the second door stop formation 18 such that the door stop part 6 has a single straight longitudinal axis. The length of flexible material is symmetrically connected to the second door stop formation 18 such that the door stop part 6 is able to hang freely from the length of flexible material with the single straight longitudinal axis of the door stop part 6 being in line with the length of flexible material.

(26) As best appreciated from FIGS. 7 and 9, the hanger part 4 is separate from the door stop part 6. The hanger part 4 is connected to the door stop part 6 by connecting means 22. The connecting means 22 comprises a bore 24 which extends transversely through the second door stop formation 18, and a pair of longitudinally extending grooves 26 which extend one on either side of the second door stop formation 18 upwardly from the bore 24 to the end of the second door stop formation 18. One end of the hanger part 4 extends along one of the grooves 26, through the bore 24, and up the other groove 26 where it is then tied to itself by a knot 28.

(27) The door stop 2 includes fastener means 30 for fastening the door stop 2 at an elevated position above a bottom part of the door 12. As best appreciated from FIGS. 7 and 8, the fastener means 30 is a removable fastener means 30. The removable fastener means 30 comprises a hook formation 32 for removably hooking over an upper hinge 34 connecting the door 12 to the door frame 16. The hook formation 32 may have a friction gripping portion 36, and an attachment portion 38 for attaching to the hanger part 4. As can best be appreciated from FIG. 8, the friction-gripping portion 36 is formed by a lower curved part of the hook formation 32. The attachment portion 38 is formed by a bent over part of the fastener means 30 forming two legs 40, 42. These legs 40, 42 are able to be pulled open to allow the hanger part 4 to slide between the legs 40, 42 as shown in FIG. 8.

(28) The door stop 2 is such that the first door-stopping size stops the door 12 in the first open position such that the first open angle is from 60-70°, and preferably 50°. The second door-stopping size stops the door 12 in the second open position such that the second open angle is from 20-30°, and preferably 25°.

(29) As shown in FIG. 7, the door stop part 6 is of a length which is approximately half the total length of the door stop 2. Generally, the door stop part 6 is approximately equal to or more than the length of the hanger part 4. Preferably, the door stop part 6 is 240 mm long, and the hanger part 4 is also 240 mm long. Thus the total length of the door stop 2, excluding the fastener means 30, is 480 mm as shown in FIG. 7.

(30) Referring now to FIG. 10, there is shown part of a second door stop 44 of the present invention. Similar parts as in the door stop 2 have been given the same reference numerals for ease of comparison and understanding.

(31) As shown in FIG. 10, the first door stop formation 8 is a two-piece first door stop formation 8. The two-piece first door stop formation 8 comprises an outer piece 46 and an inner piece 48. The outer piece 46 is a sliding fit over the inner piece 48. The outer piece 46 and the inner piece 48 enable the door stop 44 to be used with doors of different thicknesses. Depending upon the thickness of the door, the door stop 44 can be used just with the inner piece 48, or it can be used with the outer piece 46 fitted over the inner piece 48. The two-piece construction for the first door formation 8 may be advantageous if the door stop 44 is to be sold for use with fire doors and also with non-fire doors, since fire doors are typically thicker than non-fire doors.

(32) FIG. 10 also illustrates how different designs of door stops for the present invention may optionally be such that the second door stop formation 18 is provided with a finger-gripping recess 50. The finger-gripping recess 50 is advantageous for use by adults when they may be gripping the second door stop formation 18 with a view to removing the door stop 2 from the gap 14 and allowing the door 12 to close to the position shown in FIGS. 3 and 6. When gripping the second door stop formation 18, there might be a possibility that the adult might get their fingers trapped between the second door stop formation 18 and the door 12 and/or the door frame 16. The finger-gripping recess 50 helps to avoid this possibility. More specifically, the adult's fingers will be in the finger-gripping recess 50, and the adult will thus be less likely to get their fingers trapped between the second door stop formation 18 and the door 12 and/or the door frame 16.

(33) It is to be appreciated that the embodiments of the invention described above with reference to the accompanying drawings have been given by way of example only and that modifications may be effected. Thus, for example, other constructions may be employed for the hanger part 4 and the door stop part 6. The operational centre of gravity of the door stop 2 may be varied by making the centre of gravity higher than would occur in the door stop 2 shown in the drawings. This may be effected by removing inner material from the first door stop formation 8 and/or putting a weight in the top of the second door stop formation 18. Still further, the length of the first and second door stop formations 8, 18 may be varied. Varying the length of the second door stop formation 18 may vary the position at which the second door stop formation 18 crosses the edge of the door 12 in use of the door stop 2 when the second door stop formation 18 is in the gap 14 at the hinge side 10 of the door 12. The top portion of the second door stop formation 18 may be parallel-sided, or it may taper towards the top, or it may taper away from the top. Still further, the top may be a concave top. The first door stop formation 8 may taper outwardly as shown, or it may taper inwardly or it may be parallel sided. The hanger part 4 is preferably a cord but it may be made of another type of flexible material. The knot 28 may alternatively be a crimp. Individual components shown in the drawings are not limited to use in their drawings and they may be used in other drawings and in all aspects of the invention.
