Abstract
Description
- This invention relates to locks of the type which have a single operating mechanism to activate bolts at two spaced locations and in particular the invention relates to locks suitable for a sliding door or window, e.g. a patio door.
- German Patent Specification DE-B-2154320 discloses a lock for doors and windows which although of elongated form is not of sufficiently compact elongated construction for use as a sliding door lock in a narrow door frame. But it does employ an operating member in the form of a first pivoted tangent plate connected by a pin and slot mechanism to a first slider member adapted to be connected to a first bolt member, the tangent plate being connected by a second pin and slot mechanism to a second pivoted tangent plate in such a manner that clockwise rotational movement of the first tangent plate causes anti-clockwise rotational movement of the second tangent plate and vice-versa, the second tangent plate also being connected by a pin and slot mechanism to a second slider member adapted to be connected to a second bolt member so that rotation of the operating member causes the two slider plates to move in opposite directions.
- French Specification FR-A-2128173 also discloses a similar door lock with similar features but again it is not sufficiently compact for use in modern sliding door frames.
- Swiss Specification CH-A-562948 discloses a lock having a deadlock mechanism which has a locking projection or foot.
- An object of the invention is to provide a compact lock mechanism of elongated construction which enables a patio door, or a window, for example, to be bolted simultaneously at two different locations (such as the top and bottom of a patio door) by a single movement of an operating handle, the lock incorporating within the elongated construction a compact deadlock mechanism.
- Since the lock of this invention is of elongated construction, so as to occupy the minimum width, it will fit into a very narrow door or window frame.
- According to the invention, a lock for a sliding patio door or window is of elongated construction and comprises an operating member in the form of a first pivoted tangent plate connected by a pin and slot mechanism to a first slider member adapted to be connected to a first bolt member, the tangent plate being connected by a second pin and slot mechanism to a second pivoted tangent plate in such a manner that clockwise rotational movement of the first tangent plate causes anti-clockwise rotational movement of the second tangent plate and vice-versa, the second tangent plate also being connected by a pin and slot mechanism to a second slider member adapted to be connected to a second bolt member, so that rotation of the operating member causes the two slider plates to move in opposite directions, characterised in that the lock includes a deadlock mechanism comprising a plate which has a locking projection or foot adapted to be moved into a position in which it inhibits movement of the lock mechanism, and in that the slider members are elongated plates and the first bolt member is at the end of the lock remote from the first tangent plate, and the second bolt member be;ng at the end of the lock remote from the second tangent plate, the two slider plates and the locking plate being arranged parallel to each other.
- Said locking projection or foot may be adapted to block movement of one of the pins connected to one of the tangent plates. The deadlock locking plate may be moveable by engagement of a rotary cam with a cam surface on the plate such as to move the locking plate to cause said projection or foot to inhibit movement of the lock mechanism. Said rotary cam may be operable by a conventional cylinder lock.
- Preferably, the pin employed to connect one slider plate to its tangent plate passes through an aperture in the other slider plate.
- The bolting action of the lock and/or the deadlock action may be operable from either side of the lock.
- Preferably the lock includes a lock operating handle and a fixed handle for sliding the door, the operating handle being at one end of the lock and being small compared with the fixed handle which occupies substantially the remaining length of the lock.
- In the accompanying drawings:
- FIGURE 1 illustrates diagrammatically part of a patio door with a single-sided lock, embodying the present invention, incorporated in the door;
- FIGURE 2 is a section through the lock shown in Figure 1;
- FIGURE 3 is a section on the line A-A shown in Figure 2;
- FIGURE 3a is a plan view of the locking plate;
- FIGURE 3b shows a detail of the two tangent plates; and
- FIGURE 4 is a section through the same lock modified to provide a double-sided action.
- In Figure 1 is shown, in chain dotted line, part of a
patio door 10 to which is fitted alock 11 embodying the present invention. To upper and lowerdoor frame members 12, 13 respectively are fitted keepmembers 14, 15 adapted to be engaged bybolt members 16, 17 (in the form of long rods) which are to be operated simultaneously by thelock 11, thus locking the patio door both at its top and bottom. - The lock incorporates a small
pivoted operating handle 18 for bolting and unbolting the door and a largerfixed handle 19 which occupies most of the remaining axial length of the lock, for sliding the door bodily. The lock has a rigid base plate 9 which can be fixed in a recess in thedoor 10 by bolts (not shown). - The
operating handle 18 is pivoted on plate 9 and is fixed to a first tangent plate 20 (Figures 2 and 3 and 3b).Tangent plate 20 is connected to afirst slider plate 21 by a first pin and slot mechanism comprising aslot 22 intangent plate 20 and apin 23 fixed on thefirst slider plate 21.Pin 23 passes through anelongated slot 23a inslider plate 28.Slider plate 21 has a rod-like bolt member 1 6 fixed to it. -
Tangent plate 20 is also connected to a second tangent plate 24 (see Figures 3 and 3b) via a second pin and slot mechanism comprising aslot 25 intangent plate 20 and apin 26 fixed totangent plate 24.Tangent plate 24, pivoted at 27, is connected to asecond slider plate 28 via a pin and slot mechanism, theslot 29 being formed intangent plate 24 and thepin 30 being fixed to aslider plate 28 which is in turn attached to rod-like bolt member 17. - When
handle 18 is turned anti-clockwise from its position shown in Figures 1 and 2 thetangent plate 20 turns in the same direction, which is clockwise as seen in Figure 3. This causes two things to happen. Firstlyslider plate 21 is moved upwardly releasingbolt member 16 from its keeper. Secondly, and simultaneously,tangent plate 24 turns anti-clockwise (as seen in Figure 3) which movesslider plate 28 downwardly thus releasingbolt member 17 from itskeeper 15. - A deadlock enables the lock mechanism to be rendered inoperable at will.
- A cylinder lock 31 which is key-operated rotates a
cam 32 to contactcam surface 32a on lower foot 33 of aslidable locking plate 44. This will causelocking plate 44 to slide downwardly (see Figure 3a for two positions of locking plate) so as to bring theupper foot 45 of theplate 44 into the path of pin 26 (see. Figure 2) thus preventing any further movement of bothtangent plates handle 18. As shown in the drawings the deadlock has not been operated so the main bolting action of the lock can be used at will. Thelocking plate 44 is resiliently held in either the deadlocked or unlocked position by aspring 46 which ensures full travel in either direction of the locking plate. When lock 31 is operated to unlock the door, the key is turned away from the leading edge of the door, i.e. anti-clockwise as seen in Figure 1. - Figure 4 is similar to the arrangement shown in Figures 1 to 3 except that the bolting action of the lock and the deadlock can be operated from either side of the lock. It will be seen that there are two
operating handles 18, two cylinder locks 31 and also twofixed handles 19 to enable any operation to be carried out from either side. - As can be seen from the drawings the
pivoted operating handle 18 is located adjacent one end of the lock and is small compared with the larger fixed handle 1 9 for sliding the door bodily. It will be noted that thehandle 19 occupies virtually the remaining length of the lock apart from the space occupied by the operating handle. - It will also be noted that the lock is of elongated construction and that the
bolt member 16 is at the end of the lock remote from its operatingtangent plate 20, and thebolt member 17 is at the end of the lock remote from its operatingtangent plate 24. - The lock can be used as either a right-hand or left-hand operating lock by reversing the
tangent plates slider plates locking plate 44.
