Definitions

  • This invention relates to locking devices, and in particular to a locking device which, during use, is pressed into a locking position and can be released therefrom by means of a key.
  • a locking device which, during use, is pressed into a locking position and can be released therefrom by means of a key.
  • Such a device is particularly suitable for use in a vent handle locking mechanism.
  • Vents such as windows
  • a latch which is swung into position by means of a handle rotatably mounted on the vent itself.
  • the handle and latch rotate about a pivot secured to the vent, and the latch engages in a recess in, or simply abuts against, the frame of the vent which is solidly mounted in a wall or the like.
  • a number of ways of achieving locking of the handle are known.
  • the present invention aims to overcome these problems associated with the known prior art handle locking devices.
  • a locking device according to the present invention is cheap to manufacture, requires very few parts and can be activated without the use of a key.
  • a locking device adapted to be pressed, during use, into a locking position and released therefrom by means of a key, comprising a body portion, having an aperture therein for receiving a key during unlocking, an active portion for effecting locking when the device is depressed and a detent, attached to the body portion by means of a resilient web, the detent retaining the device in its locking position when depressed, wherein interaction of the key with the locking device bends the resilient web, thereby de-activating the detent and enabling the device to be biased back into its unlocked position.
  • the locking device further comprises means for receiving a biasing means which, when the detent is de-activated, urges the device back into its unlocked position.
  • the receiving means may be a spindle formed integrally with the body portion of the device for receiving a helical spring.
  • the helical spring is preferably in compression when the locking device is in its locking position.
  • the detent may include a first flange extending in a direction substantially perpendicular to the direction of motion, during use, of the locking device.
  • the active portion and the detent are formed integrally.
  • the locking device preferably further comprises means for dictating the unlocked position of the device.
  • a dictating means may include a second flange extending in a direction substantially perpendicular to the direction of motion, during use, of the device.
  • the second flange if included, preferably extends in substantially the opposite direction to the first flange.
  • the dictating means is preferably attached via a resilient support to the body portion.
  • the body portion is preferably substantially cylindrical.
  • the whole locking device may be manufactured as a one-piece plastic moulding. If this is the case, the cost of manufacture of the device is substantially less than that of each of the known prior art devices mentioned above. Hence, this is extremely important for commercial reasons.
  • a locking device according to the present invention is particularly suitable for use in a locking mechanism for a vent, such as a window.
  • a vent locking mechanism of this kind preferably comprises a handle, including a locking device according to the present invention, and a base upon which the handle is rotatably mounted, wherein the locking device engages the base when in its locking position, thereby preventing rotation of the handle, and disengages from the base in its unlocked position to allow opening of the vent.
  • the active portion When the locking device of such a mechanism is depressed, the active portion preferably enters a recess in the base and the detent interacts with a shaped part of the handle.
  • the locking device is accommodated within a recess in the handle, together with a biasing means for urging the locking device into its unlocked position.
  • the biasing means may be a helical spring or some other suitable means.
  • a locking device according to the present invention may be used with a cockspur-type handle, a handle of an espagnolette bolt system, or any other suitable type of handle.
  • a vent locking mechanism 1 comprises a handle 3 rotatably mounted, by means of a large rivet or pin 5, on a handle base 7.
  • the handle 3 includes a sideways extension or latch (not shown) which, when the handle is in its closed position, is able to engage a recess in, or abut against, the solidly mounted frame of the vent.
  • a sideways extension or latch (not shown) which, when the handle is in its closed position, is able to engage a recess in, or abut against, the solidly mounted frame of the vent.
  • the handle 3 includes a recess 9 which, when the handle 3 is in its closed position, overlays an opening 11 in the handle base 7.
  • the recess 9 is adapted to receive a locking device 13 according to the present invention.
  • the locking device 13 comprises a body portion 15 having an aperture 17 therein for receiving a key 19 during unlocking.
  • This lower portion 24 is attached to the main body 15 of the locking device 13 by means of a resilient web 25.
  • the aperture 17 in the body portion 15 extends from the top of the body portion 15 to a region adjacent the resilient web 25.
  • This spindle 27 receives a helical spring 29 within the recess 9 of the handle 3.
  • the helical spring 29 sits on a shaped shoulder 31 within the recess 9 and biases the locking device 13 into its unlocked position (as shown in figure 1).
  • the locking device 13 further includes a second flange 33 attached via a resilient support 35 to the body portion 15. During use, the second flange 33 engages a corner 37 formed in a wall of the recess 9, thereby dictating the unlocked position of the locking device 13.
  • the locking device 13 needs only to be depressed, so that the detent 21 slides past the projection 39 and engages the underside thereof. This is facilitated by the angled bearing surfaces of the detent 21 and projection 39, as shown in the drawings.
  • a locking device according to the invention is simple to use and cheap to manufacture, but sufficiently efficient and reliable to satisfy its functional requirements.
  • the locking device 13 can be made as a one-piece moulding from plastics materials.
