Definitions

  • the present invention relates to child safety gates and, more particularly, to a demountable safety gate which may be temporarily fitted across the top of a stairway in a doorway or across some other passageway to prevent access by an infant whilst allowing passage to adults.
  • Child safety gates have comprised frameworks of preassembled members, such as, welded steel tubes or rods, and have therefore occupied an undesirable amount of space when stored and transported.
  • prior safety gates have typically comprised a wicket gate hinged within a relatively wide surrounding framework by means of which the gate is secured in a required position so that the gate opening, itself, has been of significantly less width than the passageway protected by the gate.
  • the invention consists in a child safety gate comprising a generally rectangular framework having upper and lower horizontal members and upright struts extending between the horizontal members characterized in that the struts at opposite ends of the framework are assembled to adjacent ends of the horizontal members by corner fittings which at one end of the framework also serve as hinging members for hingeably connecting the gate to a support and at least one of which fittings at the opposite end of the framework includes one part of a retaining latch engageable with a cooperating part mounted on a confronting support.
  • the upper and lower horizontal members and the end struts are preferably a push fit in the corner fittings.
  • opposite ends of intermediate struts are preferably assembled to the horizontal members by means of a push fit.
  • ends of the struts may be pushed directly into preformed holes in the horizontal members and may be an interference fit therein.
  • the ends of the struts may be fitted with plastics end caps which are an interference fit in preformed holes in the horizontal members.
  • engagement of the corner fittings is preferably by means of a releasable detent mechanism.
  • the present invention provides a safety gate which may be readily assembled by an end user from a knock-down kit of parts without the need to use screws or other fastening members, adhesive or tools.
  • the invention provides a safety gate having a relatively wide access opening and which may be mounted by means of quick release fittings so that it can be rapidly demounted and removed to another location. It enables a substantially full width access opening for an adult to a stair, door or other passageway across which the gate may be fixed. When fixed directly to a wall or door frame no bottom rail is required over which an adult may trip when stepping through the gate opening.
  • the horizontal members and struts may be metal or plastics tubes or wood rods or any combination of such members. They may, for example, be made from coated steel tube of round, oval or square cross section and the corner fittings may be moulded from high strength plastics or cast from metal. Preferably, the horizontal members are oval in cross section and, in the assembled gate, are disposed with their major axes horizontal so as to optimise the firmness of the joint between horizontal members and the adjacent ends of the struts. Where the framework is constructed, for example from steel tubes, thinner gauge steel tube may be used than in prior gates because no welding is necessary.
  • each fitting may simply be formed with a vertical journal or pin for engaging a pin or journal respectively of a complementary hinge part.
  • the hinge pin may be disposed at or adjacent the outer end of a cantilever member.
  • the complementary hinge part which is hingeably connected to the corner fitting is preferably slideably engageable with a corresponding support fitting which is adapted to be fastened to the support.
  • the sliding engagement of the complementary hinge part with the support fitting is preferably by means of a dovetail joint which is snap engageable.
  • the or each corner fitting including a latch part may include an adjustable latching projection for engaging with a cooperating latch device attached to the wall door upright or other suitable support opposite the hinge so that the gate may be latched or locked in its closed position.
  • the latching projection may, for example, comprise an adjustable spindle which is screw threaded into the associated corner fitting and support a locking knob which, when the spindle has been adjusted so as to engage the cooperating latch device, can be tightened to lock the spindle in the adjusted position.
  • both corner fittings at the latching, end of the gate are provided with latching parts for engaging cooperating latch devices.
  • the invention consists in a child safety gate having a latching projection engageable with a cooperating latch device mounted on a suitable support for locking the gate in its closed position, wherein the latch device comprises a latching member behind .which the latching projection is engageable, said latching projection being engageable with the latching member by upward movement of at least the adjacent end of the gate.
  • a releasable catch member is preferably engageable with the latching projection when it is latched in the latching device to resist upward movement of the projection and release of the gate.
  • the gate has latching projections at or adjacent its top and bottom edges engageable with cooperating latch devices mounted on the wall, doorframe uprights or other suitable support, each latch device comprising a latching member behind which the cooperating projection is engageable by upward movement of the gate, and only the top latch device incorporates a releasable catch member.
  • the invention consists in a kit of parts for assembling a child safety gate of the construction described above.
  • the invention consists in a _> -

  • the invention also provides a frame comprising upright support legs for disposing adjacent opposite sides of a passageway across which the gate is to be mounted and means interconnecting the upright support legs at ends thereof which are to be positioned adjacent the floor said means being adjustable apart to wedge the frame in the passageway.
  • the mounting frame comprises two L- shaped frame members each comprising an upright leg and a horizontal leg for disposing adjacent the floor, the hori ⁇ zontal legs extending between the upright legs and being interconnected.
  • each frame member ' when uninstailed the two legs of each frame member ' are disposed at an angle to each other slightly greater than 90°, for example 100°.
  • the upright legs bend inwardly of the horizontal legs when the frame members are pushed apart, which ensures a tight fit.
  • the horizontal legs are conveniently joined together in a telescopic manner, with the end of one leg fitting within the end of the other. They are preferably adjust ⁇ able apart by means of a toggle mechanism which also serves to secure the frame in the wedged position. - 5 -
  • the toggle mechanism may comprise a pair of toggle frames hinged together at mutually adjacent ends, and pivotally connected each to one of the horizontal legs at their opposite ends.
  • the frame members may be adjust ⁇ ed apart by depressing the hinge, and retaining it in such a position when the hinge is just over-centre.

Abstract

On décrit une porte de sécurité pour enfant de structure rectangulaire à éléments supérieurs et inférieurs horizontaux (10, 12) pourvus de barres verticales (14, 16, 18) s'étendant entre lesdits éléments. Les barres terminales (14, 18) sont reliées aux extrémités des éléments horizontaux (10, 12) par des pièces de coin (22, 24, 26, 28) qui, à chaque extrémité de la structure, servent également d'éléments d'articulation (35) afin d'assembler de manière pivotante la porte à un support à l'aide d'un assemblage à queue-d'aronde se mettant en prise simultanément. Les pièces de coin (26, 28) à l'extrémité opposée de la porte s'engagent en se vissant à l'aide de broches (52) pourvues de boutons de serrage (54). Les projections (52) s'engagent dans les verrous (56) dont la partie supérieure est pourvue d'une clenche se débloquant à la main. La porte peut être facilement assemblée et désassemblée, montée et démontée. L'invention fournit également la porte sous forme de prêt-à-monter (kit) et un cadre pour le montage. Le cadre comprend une paire d'éléments en L, dont les membres horizontaux s'engagent de manière télescopique à une extrémité inférieure et se règlent à part afin de fixer le cadre dans un passage.
