Definitions

  • ABSTRACT A catch for use on a cabinet door as a temporary catch to secure the door against heavy vibration comprising a striker and a socket which is adapted to receive the striker but which can be rendered inoperative by rotating the striker into an inoperative position relative to the socket.
  • the striker comprises a base which can be mounted on a support and a pair of oppositely outwardly facing side surfaces of equal length and each formed with a shoulder.
  • the side surfaces of the striker are convexly curved.
  • the socket comprises a base adapted to be mounted on a support and has two upstanding resilient walls arranged generally in parallel and each formed with an inwardly projecting rib which is spaced from the socket base.
  • the distance between the shoulders of the striker is greater than the distance between the ribs of the socket but less than the distance between the walls of the socket and the length of the side surfaces of the striker is substantially less than the distance between the ribs of the socket.
  • the present invention relates to a catch comprising a striker and a socket which is particularly suitable for use as a door catch to prevent the door of an article such as a cabinet accidentally opening for instance when the cabinet is subjected to abnormal vibration during transport.
  • the present invention is concerned with a catch comprising a striker and a socket adapted to receive the striker, the socket and striker being so shaped and arranged that in one position of the striker relative to the socket it can enter the socket freely without interference and in another position of the striker relative to the socket it is a snap engaging fit within the socket.
  • the present invention provides a catch comprising a striker and a socket adapted to receive the striker, the striker comprising a base adapted to be mounted on a support, a pair of oppositely, outwardly facing side surfaces of equal length and each formed with a shoulder, the socket comprising a base adapted to be mounted on a support and two upstanding resilient walls arranged generally in parallel and each formed with an inwardly projecting rib thereon which is spaced from the socket base, wherein the distance between the shoulders of the striker is greater than the distance between the ribs of the socket but less than the distance between the walls of the socket and the length of the side surfaces of the striker is substantially less than the distance between the ribs of the socket whereby the striker can pass freely between the ribs of the socket when the side surfaces of the striker are aligned generally at right angles to the walls of the socket and whereby the striker is a force fit between the walls of the socket when the side surfaces of the striker are aligned generally in parallel with the walls of the
  • FIG. 1 is a perspective view showing the two components of the catch of the present invention attached to the door and body of a refrigerator,
  • FIG. 2 is a plan view showing the catch in the locked position.
  • FIGS. 3 to 5 are respectively a plan view, side elevation and end elevation of the striker of the catch shown in FIGS. 1 and 2, and
  • FIGS. 6 to 8 are-respectively a side elevation, front elevation and plan view of the socket portion of the catch shown in FIGS. 1 and 2.
  • a catch is indicated generally at 10 which comprises two components, a striker 11 and a socket 12. Both the striker 11 and the socket 12 are preferably injection moulded from a suitable synthetic plastics material such as an acetal resin.
  • FIGS. 1 and 2 the striker 11 is shown attached to a door 13 of a refrigerator and the socket 12 is shown attached to the body 14 of the refrigerator.
  • the body 14 of the refrigerator is normally provided with a bracket 15 having a slot 16 enabling the body 14 of the refrigerator to be bolted to the floor when the refrigerator is being transported. It may be necessary to bolt the refrigerator to the floor when the refrigerator is being temporarily transported or if the refrigerator is installed in a caravan or trailer.
  • the refrigerator will be provided with a conventional handle operated catch to close the door and this is not shown.
  • This type of handle operated catch is liable to become accidentally dislodged allowing the door to open if it is subjected to heavy vibration and the purpose of the catch 10 is to provide a safety catch which can be applied when the refrigerator is likely to be subjected to heavy vibration.
  • the striker 11 of the catch 10 comprises an elongate body 17 having rounded, convexly curved side surfaces 18 and 19 formed with shoulders 20 and 21 respectively.
  • the body 17 of the striker 11 is also formed with a recess 23 and a through bore 22.
  • the striker is attached to the door 13 by a screw 24 which passes through the bore 22 into a threaded bore 25 in the door 13.
  • the screw 24 can only be tightened home in the threaded bore 25 to an extent which, while normally holding the striker frictionally in position will allow the striker 11 to be manually rotated.
  • the socket 12 comprises a substantially flat body portion 26 having an elongate hole 27 enabling it to be attached to the bracket 15 with the aid of a screw 28 which passes through the bracket and into the refrigerator body 14.
  • the body portion 26 is formed with a flange 29 along one edge, which flange locates against an edge of the bracket 15 to prevent the socket 12 from rotating relative to the bracket 15.
  • upstanding walls 30 and 31 Projecting outwardly from the plate 26 are two upstanding walls 30 and 31 which are similar and which lie approximately in parallel planes.
  • a pair of inwardly extending facing ribs 32 and 33 are provided at the outer ends of the walls 30, 31 which form a restricted neck or entry to the space between the walls 30 and 31.
  • the maximum distance a between the shoulders 20,21 of the striker is greater than the distance b between the ribs 32, 33 of the socket but less than the distance c between the walls 30, 31 of the socket and the length d of the side surfaces l8, l9 (i.e., the width of the striker) is substantially less than the distance b between the ribs 32, 33.
  • the striker 11 is manually rotated 50 that it is oriented vertically and can pass freely between the ribs 32, 33 on the walls 30, 31 of the socket 12. If, however, it is desired to hold the door permanently closed in a manner which will withstand heavy vibration, then the striker is rotated manually through 90 so that it is oriented horizontally and is a snap fit between the walls 30 and 31. The door 13 is then closed and the striker is forced between the ribs 32 and 33, opening the walls 30 and 31 outwardly and then seating between the arms. When the striker is pressed fully home between the walls 30 and 31 shoulders 20, 21 engaged behind the ribs 32 and 33 to retain the striker within the socket. In order to open the door, a strong pull has to be applied to the door to withdraw the striker from the socket.
  • the catch 10 provides a quick and easy way of locking a door in the closed position against heavy vibration and rattling which can easily be rendered inoperative for normal opening and closing of the door.
  • a catch comprising a striker and a socket adapted to receive the striker, the striker comprising a base adapted to be mounted on a support and a pair of oppositely outwardly facing side surfaces of equal length,
  • each surface being formed with a shoulder
  • the socket comprising a flat, substantially planar base adapted to be mounted on a support and two upstanding resilient walls extending from one surface of the base and arranged generally in parallel spaced relationship to each other, each wall being formed with an inwardly projecting rib thereon which is spaced from said one surface of the socket base, the distance between the shoulders of the striker being greater than the distance between the ribs of the socket but less than the distance between the walls of the socket and the length of the side surfaces of the striker being substantially less than the distance between the ribs of the socket whereby the striker can pass freely between the ribs of the socket to substantially the full depth thereof when the side surfaces of the striker are aligned generally at right angles to the walls of the socket and whereby the striker is a force fit between the walls of the socket when the side surfaces of the striker are aligned generally in parallel with the walls of the socket and when forced therebetween is retained therein by engagement of the shoulders of the striker behind the ribs of the socket
