Abstract

A hinge mechanism having a first 2 and a second 4 member, the first member 2 forming part of the gate support and the second member 4 forming part of the gate, said first and second members being pivotally connected such that in a given relative position the first and second members interengage to restrict further pivotal motion. The two members are interconnected by means of a spring loaded piston 11. <IMAGE>

Description

HINGE MECHANISM This invention relates to a hinge mechanism particularly, but not exclusively, for use in child safety gates.
Safe and secure means for ensuring child safety gates remain shut at all times are of great importance. If a gate is closed without being shut completely and the catch engaged, the gate may only be resting on its catch and thereby capable of being opened by a child simply by pushing or pulling the gate.
According to the present invention, there is provided a hinge mechanism having a first and a second member, the first member forming part of the gate support and the second member forming part of the gate, said first and second members being pivotally connected such that in a given relative position the first and second members interengage to restrict further pivotal motion.
Preferably, the first and second members are orthogonally disposed.
Preferably, the first and second members are interengageable when the gate is in a closed position such that the second member is required to be lifted to break the interengagement before the second member can be pivoted to open the gate.
Preferably, the members are interconnected by means of a spring loaded piston which biases the two members to interengage.
Preferably, the members are interconnected by means comprising a spring loaded piston having an end member of greater width than the spring, against which the spring is compressed.
The spring may be disposed around the piston which is connected to the second member such that the spring is compressed when the second member is lifted causing the second member to be biased towards the interengaged position with the first member.
Preferably, the first member is hollow to form a housing for the pivotal connection means.
Preferably also, the piston end member is disposed within the hollow first member with the spring trapped between the end member and the inner face of the hollow first member.
Preferably, the interengagement of the first and second members is provided by a corresponding recess in the first or second member in which the other member fits.
Embodiments of the present invention will now be described with reference to the accompanying drawings in which: Fig 1 shows a perspective view of a hinge mechanism in a closed position; Fig 2 shows a cross-section of the hinge mechanism of Fig 1; Fig 3 shows a perspective view of the hinge mechanism of Fig 1 in an open position; Fig 4 shows a perspective view of a second embodiment of the hinge mechanism in accordance with the present invention in a closed position; Fig 5 shows a cross-section of the hinge mechanism of Fig 4; and Fig 6 shows a perspective view of the hinge mechanism of Fig 4 in an open position.
Referring to the drawings, a hinge mechanism 1 has a first member 2 in the form of a gate support and a second member 4 forming part of the gate. The first 2 and second 4 members are orthogonally disposed with the first member 2 being a vertical support of the gate and the second member 4 being the top horizontal bar of the gate. The first 2 and second 4 members are pivotally connected at a connection 6. The pivotal connection 6 is in the form of a vertical projection 8 of, or attached to, the second member 4 into an opening 14 in the portion of the first member 2 adjacent to the projection 8 of the second member 4, the projection 8 being in the form of a spring loaded piston 10 which acts inside a hollow cavity 12 at the top of the first member 2 and through an opening 14 into the hollow cavity 12.The piston 10 is formed of a shaft 9 around which the spring 16 is positioned, and an end member 11 of a width greater than the diameter of the spring 16 at the end of the shaft 9, such that the spring 16 is trapped between the end member 11 and the opening surround 13. The spring 16 is positioned on the opposite side of the opening 14 to the second member 4.
The first 2 and second 4 member are interengageable with one member 2 or 4 having a recessed area 18 in the side adjacent to the other member corresponding to the shape of the adjacent portion 20 or 22 of the other member 4 or 2.
The connection 6 acts through the base 23 of the recessed area 18 and the side of the other member 20 or 22 adjacent to the recessed area 18.
Figs 1-3 show a first embodiment of the invention wherein the first member 2 has a recess 18 in which the adjacent portion the 20 of the second member 4 fits when the gate is closed, in this position the spring 16 is uncompressed around the shaft 9 of the piston 10.
In use the second member 4 is lifted to disengage the two members 2 and 4 by lifting the second member 4 above the recessed area 18 of the first member 2. On lifting the second member 4, the spring 16 is compressed between the end member 11 of the piston 10 and the opening surround 13 as the piston 10 is raised through the opening 14. When the first 2 and second 4 members are not interengaged the second member 4 may be rotated through an angle horizontally as the gate is opened. When the gate is pivoted towards the closed position, the spring 16 biases the second member 4 downwardly via the piston 10 and thus ensures that the second member is pulled into engagement with the recessed area 18 once the portion 22 of the second member 4 reaches alignment with the recessed area 18.
Figs 4-6 show a second embodiment of the invention wherein the recessed area 16 is in the second member 4 and the first member 2 fits into the recessed area 16.
Modifications and improvements may be incorporated without departing from the scope of the invention.

Claims (10)

1 A hinge mechanism for a gate having a first and a second member, the first member forming part of the gate support and the second member forming part of the gate, said first and second members being pivotally connected such that in a given relative position the first and second members interengage to restrict further pivotal motion.
2 A hinge mechanism as claimed in Claim 1, wherein the first and second members are orthogonally disposed.
3 A hinge mechanism as claimed in Claim 1 or Claim 2, wherein the first and second members are interengageable when the gate is in a closed position such that the second member is required to be lifted to break the interengagement before the second member can be pivoted to open the gate.
4 A hinge mechanism as claimed in any one of the preceding claims, wherein the members are interconnected by means of a spring loaded piston which biases the two members to interengage.
5 A hinge mechanism as claimed in any one of the preceding claims, wherein the members are interconnected by means comprising a spring loaded piston having an end member of greater width than the spring, against which the spring is compressed.
6 A hinge mechanism as claimed in Claim 4 or Claim 5, the spring is disposed around the piston which is connected to the second member such that the spring is compressed when the second member is lifted causing the second member to be biased towards the interengaged position with the first member.
7 A hinge mechanism as claimed in any one of the preceding claims, wherein the first member is hollow to form a housing for the pivotal connection means.
8 A hinge mechanism as claimed in any one of Claims 5, 6 or 7, wherein the piston end member is disposed within the hollow first member with the spring trapped between the end member and the inner face of the hollow first member.
9 A hinge mechanism as claimed in any one of the preceding claims, wherein the interengagement of the first and second members is provided by a corresponding recess in the first or second member in which the other member fits.
