Abstract
A security device for a closure member (eg a door) and a frame member comprises a slidable catch-plate 1 mounted on one of the members and a cooperating latch 10 mounted on and extending outwardly from the other member. A chain is secured to the latch and comprises a plurality of articulated links terminating in a stop 14. The catch-plate is formed with a slot which is open at one end and is dimensioned to enable the catch-plate to slide over the latch. The slot has a widened section at a position intermediate its ends to define an opening through which the chain can pass but not the stop. The arrangement is such that the catch-plate is movable between a first position in which it is clear of the latch and a second position in which the catch-plate moves over the latch with the chain positioned within the opening.
Description
SECURITY DEVICES
This invention relates to a security device for a closure member and aframe member and is particularly, though not exclusively, concerned with a security device for a door and door frame.
Door chain systems are known which enable a door to be partially opened to allow a person seeking entry to be identified before the door is fully opened. Such systems generally include a chain secured to a door frame and formed at one end with a slide which in use is positioned within a restricted guideway of a catch-plate secured to a door. Such systems require a degree of manual dexterity for effective operation which many old and handicapped people do not possess. They also require reasonably good eye-sight to position the chain slide into the guideway of the catch plate.
Security bolt systems are, of course, also well known. These again require a degree of manual dexterity for effective operation which many old and handicapped people do not possess. Also, conventionally, chain and bolt systems are separate one form another.
The present invention sets out to provide a security device which has features of conventional door chain systems but which can be operated simply by imparting movement to a slidable catch-plate through contact with a handle projecting from the catch-plate. The present invention also provides a security device which incorporates features of conventional chain and security bolt systems, both systems being operated simply by imparting movement to a slideable catch plate through contact with a projecting handle. The degree of manual dexterity and sightedness required for effective operation is consequently significantly reduced.
According to the present invention in one aspect, there is provided a security device for a closure member and a frame member, the device comprising a slidable catch-plate mounted on one of the members, a cooperating latch mounted on and extending outwardly from the other member and a chain secured to the latch including an articulated link terminating in a stop, the catch-plate being formed with a slot which is open at one end and is dimensioned to enable the catch-plate to slide over the latch and the slot having a widened section at a position between its ends to define an opening through which the chain can pass but not the StOPs the arrangement being such that the catch-plate is movable between a first position in which it is clear of the latch and a second position in which the catch-plate moves over the latch with the chain positioned within the opening.
The catch-plate may be mounted for sliding movement within a guideway of a bracket formed with a bordered slot through which a handle of the catch-plate protrudes, movement of the handle being restricted by the boundaries of the slot. Alternatively, the catch-plate may be mounted for sliding movement between upper and lower spaced guides.
The handle may be mounted for pivotal movement relative to the catch-plate. Thus, the handle may include sideways extending spindles which locate within apertures of brackets secured to the catch-plate. In this arrangement, the handle may include a rearwardly extending peg which locates within slots formed in the catch-plate and a backing plate positioned between the catch-plate and the closure or frame member to which the security device is secured. The slot formed in the backing plate may include a stop or lug which precludes movement of the peg and therefore the catch-plate until the handle has been pivoted to traverse the stop. The stop is preferably sited so that once the peg has traversed the stop the catch-plate is positioned so that the latch is sited within the slot away from its widened section.
The latch may comprise a forwardly extending ledge of a bracket secured to one of the members. The chain may be secured to the latch through a pivot block which permits limited movement of the chain away from a line drawn normal to the member to which the bracket is attached.
The stop may comprise a pair of discs secured to the end of the chain remote from the latch.
The chain preferably comprises a plurality of articulated links. The chain construction may be such that it does not deviate substantially from its longitudinal axis when extended. Thus, each link may comprise a pair of articulated platelets connected together by spacers, neighbouring pairs being connected through pivot pins.
In another aspect, there is provided a security device which comprises an assembly of a catch plate, a latch and a chain including an articulated link secured to the latch and means for sliding the catch-plate from an operative position to a position in which an aperture formed in the surface of the catch-plate lies between the point at which the chain is secured to the latch and a frame or closure member to which the latch is secured, the size of the aperture being such that the chain can pass through the aperture but not the stop.
The latch may be so shaped or may be formed with a slot to allow the catch-plate to pass behind the point of connection of the chain to the latch.
Alternatively3 the catch-plate may be formed with an open-ended slot to receive the latch.
The invention will now be described by way of example only with reference to the accompanying diagrammatic drawings in which:
Figures 1 to 3 are isometric views of a security device in accordance with the invention in three different positions;
Figure 4 is a sectional view of a feature of the device shown in
Figures 1 to 3;
Figure 5 is a plan view of a latch and chain of the security device illustrated in Figures 1 to 4;
Figure 6 is an isometric view of an alternative security device in accordance with the invention;
Figure 7 is an isometric view of a feature of the device shown in
Figure 6;
Figures 8 and 9 are isometric views equivalent to those of Figures 6 and 7 respectively showing the illustrated device in different positions;
Figures 10 and 11 are isometric views equivalent to those of Figures 8 and 9 showing the illustrated device in different positions;
Figures 12 and 13 are isometric views equivalent to those of Figures 10 and 11 showing the illustrated device in different positions;
Figure 14 is a section taken through a handle of the device shown in
Figures 6 to 13; and
Figures 15 and 16 are respectively side sectional and plan views from above of the chain system illustrated in Figure 6.
The security device illustrated in Figures 1 to 5 comprises a robust metal catch-plate 1 mounted for sliding movement within a guideway defined by a bracket 2 secured to one side of a door 3. The catch-plate includes a projecting handle 4 which protrudes through a slot 5 formed in the face of the bracket 2. The extent of sliding movement of the handle, and therefore the catch-plate, is determined by the length of the slot 5. The catch-plate is rounded at one end and is formed with an open-ended slot 6 which is widened at a position intermediate its ends to define an opening 7.
The end of the catch-plate remote from its rounded end is generally rectangular. Other shapes of catch-plate could, of course, be adopted.
Also, materials other than metal may be used provided they have the required robust physical properties.
Secured to a door frame 8 is robust metal bracket 9 including an outwardly extending latch 10. The thickness of the latch 10 is less than the height of the slot 6 to enable the catch-plate 1 to slide over the latch and take up the position shown in Figure 2. The starting position of the catch-plate 1 is shown in Figure 1. Secured to the free end of the latch is a chain 11 which comprises a plurality of articulated links 12 and terminates in a stop 14 comprising a pair of metal discs. Other forms of stops could of course be employed.
The chain links 12 comprise pairs of articulated platelets 15 connected through tubular spacers 16. When extended, the chain does not deviate substantially from its longitudinal axis, its construction avoiding buckling.
As will be seen from Figures 4 and 5 the chain is attached through a pivot block 17 to the latch 10 of the bracket 9 by a rivet pin 18. As will be seen from Figure 5 sufficient clearance is provided between the overlapping surfaces of the latch and the pivot block to allow the chain to pivot freely through for example, 5 to each side of a line drawn normal to the door frame. This pivotal movement allows the chain to follow the catchplate as the door 3 opens and closes.
As will be seen more clearly from Figure 3, the opening 7 is wide enough to enable the links 12 of the chain to pass through but not the stop 14. The width of the slot 6 to each side of the opening 7 is less than the width of the links 12 of the chain to ensure that the chain is held captive within the opening. Movement of the door 3 is, therefore, restricted by the stop 14 engaging the face of the catch-plate 1 remote from the door 3.
To summarise, in the position shown in Figure 1 of the drawings, the security device is inoperative and the door can be opened to its full extent.
To operate the security device, the catch-plate 1 is slid horizontally while the door is closed by simple contact with the projecting handle 4 to the position shown in Figure 2 in which the latch 10 is trapped within the confines of the slot with the chain positioned within the opening 7. If the door is now opened the chain links 12 pass through the opening 7 until the stop 14 engages the face of the catch-plate 1 remote from the door 3.
Further opening of the door is thereby prevented. The assembly of the catch-plate 1, the latch 10 and the chain 11 and the fixings to the door and frame, are sufficiently robust to prevent forceable entry with the security device in operation. To release the security device after identifying a person seeking entry, the door is returned to the position shown in Figure 2 and the catch-plate 1 slid to the position shown in Figure 1 simply by imparting the necessary horizontal movement to the catch-plate 1 through the projecting handle 4.
Thus, the security device can be operated with the minimum of dexterity simply by imparting horizontal movement to the catch-plate 1 through the projecting handle 4. The device can also readily be operated by the partially sighted or the blind once the position of the projecting handle has been recognised.
The security device described can be used on doors which open to the left or to the right and on windows.
The security device illustrated in Figures 6 to 16 is similar to that described above with reference to Figures 1 to 5 but includes the additional feature that, in one of its operating positions, it acts as a conventional security bolt. As for the previous embodiment, the security device comprises a robust metal catch-plate 21 mounted for sliding movement within upper and lower guideways 22 secured to one side of a door 23. The catch-plate is rounded at one end and is formed with an open-ended slot 24 which is widened at a position intermediate its ends to define an opening 25. The end of the catch-plate remote from its rounded end is generally rectangular. Other shapes of catch-plate could, of course, be adopted.
Also, materials other than metal may be used provided they have the required robust physical properties.
Secured to the side of the catch-plate 21 remote from the door 23 are a pair of forwardly projecting brackets 26 formed with apertures within which are supported sideways projecting spindles 27 of an operating handle 28. The dimensions of the apertures and spindles 27 are such that the handle 28 can pivot about the spindles 27. The end of the handle 28 which faces the door 23 is formed with a rearwardly projecting peg 29, this peg protruding through a suitably sized aperture 30 formed in the catch-plate 21. The peg 29 can be seen more clearly in Figures 7, 9, 11 and 13. The extent of upwardly and downwardly pivotal movement of the peg 29 and thus the handle 28 is determined by the vertical extent of the aperture 30.
This feature is illustrated more clearly in Figure 14. As will be seen from
Figure 7, the peg 29 tracks within a shaped slot 31 of a backing plate 32.
The weight of the handle 28 ensures that the lug normally locates against the uppermost rim of the aperture 30. The backing plate is spaced from the door 23 by spacing bars 33.
The slot 31 has a downwardly projecting stop 34A and an upwardly projecting step 34B.
Secured to a door frame 35 is robust metal bracket 36 including an outwardly extending latch 37. The thickness of the latch 37 is less than the height of the slot 24 to enable the catch-plate 21 to slide over the latch and take up the position shown in Figures 8 and 9 and the position shown in Figures 10 and 11 in which the chain 38 has passed through the opening 25 of the catch-plate 21. In this position, the peg 29 engages one side of the stop 34. The starting position of the catch-plate 21 is shown in Figures 6 and 7. Secured to the free end of the latch is a chain 38 which comprises a plurality of articulated links 39 and terminates in a stop 40 comprising a pair of metal discs. Other forms of stops could be employed.
As will be seen more clearly from Figures 15 and 16, the chain links 39 comprise pairs of articulated platelets 41 connected through tubular spacers 42. As for the chain 11 of Figures 1 to 5, when extended, the chain does not deviate substantially from its longitudinal axis, its construction avoiding buckling.
In the positions of Figures 8 to 11, the locking device is in the positions equivalent to those shown in Figures 2 and 3 respectively. The locking device of Figures 6 to 16 has the added advantage of acting as a security bolt in addition to a security chain. To achieve this effect, the handle 28 is pivoted to move the peg 29 out of its engagement with the stop 34A and over the step 34B. It can be moved once more to the position shown in Figures 12 and 13. In this position, the chain 38 is located within the relatively narrow slot 24 and is prevented from passing to its extended position shown in Figure 10. Also, cooperation between the peg 29 and the stop 34A and step 34B precludes movement of the catch-plate to the relatively open positions shown in Figures 10 and 11 and the open positions shown in Figures 8 and 9.
As will be seen from Figures 15 and 16 the chain 38 is attached through a pivot block 44 to the latch 37 of the bracket 36 by a rivet pin 45.
As will be seen from Figure 16 sufficient clearance is provided between the overlapping surfaces of the latch and pivot block to allow the chain to pivot freely through, for example, 5 to each side of a line drawn normal to the door frame. This pivotal movement allows the chain to follow the catchplate as the door 23 opens and closes.
As will be seen more clearly from Figure 10, the opening 25 is wide enough to enable the links 39 of the chain to pass but not the stop 40. The width of the slot 24 to each side of the opening 25 is less than the width of the links 39 of the chain to ensure that the chain is held captive within the opening. In the positions shown in Figure 10, therefore, movement of the door 23 is restricted by the stop 40 engaging the face of the catch-plate 21 remote from the door 23.
Also, in this position shown in Figures 12 and 13, the height of the slot 24 is less than the height of the chain links 39 to prevent opening of the door 23. The catch-plate then operates as a bolt.
To summarise, in the positions shown in Figures 6 and 7 of the drawings, the security device is inoperative and the door can be opened to its full extent. To operate the security device, the catch-plate 21 is slid horizontally by simple hand contact with the projecting handle 28 to the position shown in Figures 8 and 9 in which the latch 37 is trapped within the confines of the slot with the chain positioned within the opening 25. If the door is now opened the chain links 39 pass through the opening 25 until the stop 40 engages the face of the catch-plate 21 remote from the door 23.
Further opening of the door is thereby prevented. To operate the bolt feature of the security device, the handle is pivoted upwardly to move the peg 29 out of engagement with the stop 34 and the catch-plate moved once more to the position shown in Figures 12 and 13 in which the chain is trapped within the slot 24. The door 23 cannot now be opened. The assembly of the catch-plate 21, the latch 37 and the chain 38 and the fixings to the door and frame, are sufficiently robust to prevent forceable entry with the security device in operation.
Thus, the security device can be operated with the minimum of dexterity simply by imparting horizontal and lifting movements to the catch-plate 21 through the projecting handle 28. The device can also be readily operated by the partially sighted or the blind once the position of the projecting handle has been recognised.
The security device described can be used on doors which open to the left or to the right and on windows.
It will be appreciated that the foregoing is merely exemplary of security devices in accordance with the invention and that modifications can readily be made thereto without departing from the true scope of invention. Thus, the catch-plate 1 or 21 may be secured to the frame 8 or 35 with the bracket 9 or 36 and latch 10 or 37 secured to the door 3 or 23.
Also, the shape and materials of the catch-plate, the latch and the chain may be different from those described and the shape of the projecting handle 4 may be other than rod-shaped. Furthermore, the latch may include a slot or may be shaped to define a recess into which a close-ended catch-plate can slide, the catch-plate in this arrangement simply including an aperture.
