Description

(54) IMPROVEMENTS IN DOG DOORS (71) We, REILOR LIMITED of Blackpool Road, Preston, County of Lancaster, a British Company; do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to animal or pet doors of the kind capable of being opened from both sides and is a modification of or improvements in the invention described in Specification No. 1 451 615.
In the Specification of our Patent No. 1 451 615 there is described a cat or other animal door comprising a rectangular frame moulded in a plastics material for attachment to a door opening, the vertical sides of the frame being provided with inwardly extending flanges, a second rectangular frame of substantially U shape with flanges on the outer edges of the second frame to engage the flanges on the first frame, pivot sockets on the end of each leg of the second frame engaging in recesses in the first frame and a making up and anchoring member to locate and retain the pivot sockets of the second frame in the recesses of the first frame, a door flap pivoted on the sockets on the legs of the second frame on the side of the first frame opposite the second frame to allow the door flap to pivot in one direction and the door flap and the second frame to pivot together in the opposite direction.
The door described in Specification No. 1 451 615 is very satisfactory for cats or other relatively small animals but is not suitable for large dogs and the object of the invention is to provide for the passage of dogs and to provide an integral means of fastening to prevent unauthorized persons or other animals from entering the building in which the dog is normally accommodated.
As well as being popular in temperature climates the doors are also popular in subzero climates since being made of a plastics material they do not damage the animals noses in very cold weather and it has also been found necessary to shield the magnet keepers from possible contact with the animals.
The frames for the doors may be extruded from a plastics material or may be injection moulded.
According to one aspect of the present invention there is provided a pet door of the kind capable of being opened from both sides comprising an outer rectangular frame of channel shape extruded from a plastics material for attachment to a door opening, the inner member of the channels on the sides and bottom of the frame being provided with inwardly extending flanges, a second rectangular channel frame of substantially U shape of a plastics material to engage the flanges on the outer rectangular frame, reinforcing moulded channel corner members attached inside the channels of the outer rectangular frame with holes in the upper reinforcing members to provide sockets for the ends of a rod on which the second rectangular frame is pivoted, a door flap pivoted on the rod inwardly of the second rectangular frame to open in the opposite direction from the second rectangular frame, a magnet mounted on the outer side of a flange on the bottom of the flap to engage a metal keeper forming one side of a box member attached to the inner side of the bottom channel member of the second rectangular frame, a second magnet being mounted on the bottom channel member of the second rectangular frame parallel to the metal keeper thereon for engagement by a keeper on the outer bottom flange of the outer rectangular frame and bolts mounted to slide in the flap to engage the outer rectangular frame and the second rectangular frame to prevent the door from opening.
According to another aspect of the present invention there is provided a pet door of the kind capable of being opened from both sides, comprising an outer rectangular frame of channel section made from plastics material for attachment to a door opening, the inner member of the channel section on the sides and bottom of the outer rectangular frame being provided with inwardly extending flanges, a second rectangular chennel section frame made of plastics material and of substantially U-shape to engage the flanges of the outer rectangular frame, the channels of the outer rectangular frame having moulded reinforcing members at the corners thereof and the opposite sides of the outer rectangular frame having holes to provide sockets for the ends of a rod on which the second rectangular frame is pivoted, a door flap pivoted on the rod inwardly of the second rectangular frame to open in the opposite direction from the second rectangular frame, a system of cooperating magnets and keepers for releasably securing (i) the outer side of a flange on the flap to the inner side of the bottom of the second rectangular frame and (ii) the latter to the outer side of the bottom flange of the outer rectangular frame, and bolts mounted to slide in the flap to engage the outer rectangular frame and the second rectangular frame to prevent to door from opening.
The invention will be described with refer ence to the accompanying drawings:- Fig. 1 is a perspective view of a door from the front; Fig. 2 is an elevation of one half of the door from the rear side; Fig. 3 is a vertical section on line 3-3 Fig. 2; Fig. 4 is a similar section showing the front door partly open; Fig. 5 is a similar section showing the rear door partly open.
A door A is formed with a rectangular frame 1 a second U shaped frame 2 and a flap 3.
The rectangular frame 1 is extruded from a plastics material of channel shape reinforced at the corners with moulded channel shaped L members 4 recessed to accommodate the outer members 5 of the frame which are welded thereto. The channel members are formed with inwardly extending flanges 6.
The second U shaped frame 2 also of channel shape is extruded from a plastics material to engage the flanges 6 on the rectangular frame 1. The legs of the second frame 2 are pivoted to the reinforcing members 4 on the upper side of the rectangular frame 1 on a rod 7 passing through holes in the reinforcing member and through holes in the legs.
The flap is pivoted on the rod inwardly of the second frame 2 to open in the opposite direction from the second frame.
A magnet 8 is mounted on the outer side of a flange 9 on the bottom of the flap 3 to engage a metal keeper 10 forming one side of a plastics box member of the second frame 2 to mask the keeper 10 from contact with the animal.
A second magnet 11 is mounted on the bottom channel member of the second frame 2 parallel to the metal keeper 10 thereon for engagement by a keeper 12 on the outer bottom flange of the rectangular frame 1, the magnet 11 again being masked from contact with the animal.
A flexible strip 13 of rubber or a plastics material of channel shape with a flange 14 along one edge is applied over the inner flange 15 of the upper channel member of the rectangular frame 1 with the rubber or plastics flange overlaying the outer side or front of the legs of the second frame and the flap to act as a weather and wind guard for the door.
The flap 3 formed from a plastics material with raised panels and ribs 16 for reinforcement, at each side of the flap are formed with a bore to receive bolts 17 with L shaped upper ends sliding in slots 18 in the back of the flap. The bolts 17 pass through guides 17a. The bolts 17 when extended pass through holes 19a in the flap 3 and through holes 19 in the bottom of the second frame and holes 20 in the rectangular frame to prevent the opening of the door from either side.
The upper ends of the side rib are flattened to apply friction to the bolts when in the raised position to prevent rattle then the door is free for operation. The slots 18 for the bolts 17 may be L shaped to accommodate the upper ends of the bolts 17 when in the inoperative position.
The door A for large dogs are of a size to allow the passage of persons and accordingly means must be provided for preventing entrance as required.
The frame 1 is secured to the door opening by screws passing through holes 21 in the inwardly extending flange of the rectangular flange.
WHAT WE CLAIM IS: 1. A pet door of the kind capable of being opened from both sides comprising an outer rectangular frame of channel shape extruded from a plastics material for attachment to a door opening, the inner member of the channels on the sides and bottom of the frame being provided with inwardly extending flanges, a second rectangular channel frame of substantially U shape of a plastics material to engage the flanges on the outer rectangular frame, reinforcing moulded channel corner members attached inside the channels of the outer rectangular frame with holes in the upper reinforcing members to provide sockets for the ends of a rod dn which the second rectangular frame is pivoted, a door flap pivoted on the rod inwardly of the second rectangular frame to
