Definitions

• the present invention relates generally to a lock arrangement and more specifically to a lock arrangement that includes a plate element which has integrated therewith front functions, such as latch bolt and lock bolt controlling and driving functions.
• the invention also relates to a plate element included in such a lock arrangement.
• Certain known locks include a face plate and a box which can be releasably connected to the face plate and which houses the lock mechanism. This enables specific products to be handled in a fairly rational manner.
• Swedish Patent Specification SE7601429-9 in the name of GKN-Stenman AB describes one such solution.
• One object of the present invention is to provide a lock arrangement of the kind mentioned in the introduction, with which manufacture can be automated with simplified stock- keeping on the one hand, and which fulfils high security demands on the other hand.
• the invention is based on the realisation that all front-located functions, such as controlling and driving the bolts included in the lock arrangement can be accommodated in a plate element, provided that said unit is designed correctly.
• the inventive lock arrangement avoids the aforesaid drawbacks associated with known technology.
• the inventive lock arrangement includes a plate element that surrounds the front-located functions. The functions are therewith protected against damage, particularly when the plate element is comprised of high strength material. Moreover, integration of the front-located functions in the plate element enables modularization of the lock arrangement, thereby requiring a smaller number of component parts to be kept in stock and/or a greater variation of lock arrangements to be on offer.
• Fig. 1 is a perspective exploded view of an inventive lock arrangement
• Figs. 2a-c are respective views of a plate element included in the lock arrangement of Fig. i;
• Figs. 3a and 3b are respectively a perspective view and a side view of an alternative plate element according to the invention.
• Figs. 4a and 4b are respectively a perspective view and a side view of a further alternative plate element according to the invention.
• Figs. 5a and 5b are respective views of follower units included in the lock unit according to the invention.
• Figs. 5c and 5d are respective views of the follower units of Figs. 5a and 5b when fitted in the lock housing at different back sets.
• Fig. 1 is a perspective illustration of the lock arrangement with the box and the lock cover removed.
• the lock arrangement comprises a plate element 10 that includes a face plate 11 and a bar 12 of U- shaped cross-section welded to the face plate.
• the shape of the U-bar will be apparent from Fig. 2c for example, from which it will be seen that said bar surrounds all front-located lock functions, such as the control and drive of a latch bolt 13 and a lock bolt 14.
• the plate element 10 will be described in more detail hereinafter with reference to Figs. 2a-c.
• the lock arrangement also includes a housing that comprises a box 21 and a cover 22.
• These lock components are a mirror image to otherwise identical components fitted to the U-bar 12 by means of fasteners, in the illustrated case screws and screw-threaded sleeves 23a, 23b, which extend through holes 21d in the box and corresponding holes 22d in the lock cover.
• the U-shaped bar therewith encloses the control and drive functions of the bolts in a sideways direction, i.e. in a direction towards the main surfaces of the box and the lock cover.
• the holes 21 d and 22d coincide with through-penetrating holes 12a, 12b in the plate element.
• the box and the lock cover also include respective lips 21a-c and 22a-c which extend at right angles to the bottom and cover and which function as side surfaces in the assembled state of the lock arrangement.
• the lock arrangement also includes follower units or follower modules, in the illustrated case a cylinder follower unit 30 and a handle follower unit 40, these units being described below in more detail with reference to Figs. 5a-c.
• the follower units are fitted between the box 21 and the lock cover 22 and are provided to this end with through-penetrating holes that coincide with holes 22a in the cover 22 and corresponding pins 21e provided in said box, said pins co-acting with threaded sleeves 23 c inserted through the holes 22e.
• Fig. 2a corresponds to the view shown in Fig. 1, but with the box and the follower units omitted.
• Fig. 2b is a side view in which the U-bar 12 have been partly cut away in the region of the latch bolt bearing and control means.
• the latch bolt is adapted to move forwards and backwards in a space defined partly by the actual U-bar 12 and partly by a generally U-shaped element 15 shown in section in Fig. 2b.
• the U-shaped element 15 is comprised of bent metal sheet riveted or welded to the U-bar 12 and comprised of the same material as said bar.
• the U-shaped element includes an opening for receiving an arm 16 which is pivotally mounted on a hollow pin which coincides co-axially with the anchoring element disposed in the hole 12b and which functions to control movement of the bolt 13.
• the arm 16 engages a waist 13a on the bolt 13 and causes the bolt to move between a first outwardly extended position shown in the figure, and an inwardly withdrawn second position (not shown), as the arm is rotated about its pivot point.
• the arm 16 includes a lower end surface 16a which functions as a pressure point when manoeuvring the bolt 13.
• the U-shaped element 15 has several functions. Firstly, it functions as a guide for the bolt 13. Secondly, it functions to reinforce the U-bar 12, therewith stiffening the bar and thereby enhancing its resistance to damage. Thirdly, said element functions as a guard against manipulation of the lock; it prevents manipulation from outside the lock through the opening that is formed when the latch bolt is pressed into its withdrawn position.
• That part of the lock bolt 14 hidden by the U-beam 12 has been shown in a broken line in Fig. 2b. It will be seen that the bolt is pivotally mounted about the point 12a, i.e. the anchoring hole that coincides with the hole 23 a in the lock cover.
• the U-bar which is made of high strength material, such as high- strength steel, encloses the control means and the pivotal bearing means of the lock bolt, a higher degree of security is achieved.
• an existing component - an existing anchoring element - can be used as the shaft about which the lock bolt rotates, therewith reducing the total number of components of the lock arrangement.
• the latch bolt 14 may be pivotally mounted on a tubular element. When fitting the box 21 and the lock cover 22, a fastener, such as a rivet or a screw, is inserted through the hollow pin. This results in a very strong pivot shaft.
• the pivot bearing is provided in the U-bar, the bearing point can be placed close to the face plate 11.
• the lock bolt to be configured or designed to fill substantially all of the hole provided in the face plate for accommodating the bolt, in the state of the lock shown in the figures.
• an unauthorised person wishing to manipulate the lock will have more difficulty in accessing the lock interior from the face plate side of said lock.
• the element that functions as a lock bolt pivot shaft is preferably a combination of a screw and sleeve 24a, 24b.
• said element may consist of a rivet joint.
• the U-bar can be strengthened still further by providing respective edges of the track along which the bolt moves with an inwardly facing flange (not shown) that functions as a force- absorbing zone.
• Figs. 2a-c illustrate a plate element that includes a lock bolt and a latch bolt.
• the inventive plate element may, of course, be provided with other bolt combinations.
• FIG. 3a and 3b illustrate a plate element 10' which is provided with two latch bolts 13, 13', of which the lower latch bolt 13 is mounted in precisely the same way as the bolt described with reference to Figs. 2a-c and the upper bolt 13' is mounted in a corresponding manner, i.e. with the aid of a U-shaped element (not shown) provided in the U-bar 12.
• the face plate 11' is provided with two latch bolt accommodating openings and the construction is mirror-imaged vertically.
• the face plate also includes an opening for accommodating an interlocking bolt 17 which is used typically for daytime locking purposes and which is also constructed in the form of a module (not shown).
• the U-bar is identical with the earlier described bar, thereby simplifying and facilitating stock-keeping and assembly of respective lock components.
• Figs. 4a and 4b illustrate a further embodiment of the inventive plate element, referenced 10".
• This plate element does not include a latch bolt, but does, on the other hand, include a lock bolt 14 which is identical to the bolt described above with reference to Figs. 2a-c.
• the cylinder follower unit 30 is generally square and includes the drive means found with conventional cylinder followers.
• the unit 30 includes a through-penetrating opening 31 for receiving a dogging element (not shown) at a lock cylinder or a knob.
• the follower is of the so-called "butterfly" type, where the follower is adapted to rotate through about 90 degrees. It will be understood, however, that this does not exclude the use of other types of followers, such as cruciform followers where the follower is adapted for rotation through 360 degrees.
• the cylinder follower unit 30 is adapted to communicate with the bolt 14 through the medium of a pin 32 and a link arrangement 14a.
• the pin 32 is thus moved up or down, depending on the direction of rotation of the follower and of the movement of the pin, wherewith the bolt 14 rotates about the shaft 12a between the outwardly extended position shown in the figures and an inwardly withdrawn position (not shown).
• the cylinder follower unit 30 and the handle follower unit 40 are mutually connected by a link arrangement 35 in the case of the illustrated embodiment, thereby enabling withdrawal of the latch bolt 13 to be achieved by rotation of the cylinder follower unit 30.
• Fig. 5c shows the cylinder follower unit fitted in a lock that has a back set referenced "d" in the figure.
• the cylinder follower unit is mounted in a box 21' of greater width.
• the gap between the bolt drive and the pin 32 is bridged by giving the link arrangement 14a an appropriate length. This provides complete flexibility with regard to the back set and box measurement, with the lower limit given by the minimum measurement shown in Fig. 5c.
• the handle follower unit 40 is adapted to communicate with the arm 16 that controls movement of the latch bolt 13 between its extended and withdrawn positions.
• a pressure rod 42 of appropriate length referenced 42 in Fig. 5c and 42' in Fig. 5d.
• the handle follower is caused to rotate by means of a handle, or knob (not shown), that has a square pin inserted in a square opening 41 in the handle follower.
• the handle follower unit 40 includes an arrangement which when the follower is rotated clockwise, as shown in the figure, the rod 42 presses against the surface 16a of the arm 16. to the left in the figure.
• the arm 16 is therewith caused to rotate clockwise so that the upper part of the arm that engages the waist 13a in the bolt 13 steers the bolt positively or forcibly towards its withdrawn position (not shown).
• the spring-loaded handle follower is caused to return to its starting position, the similarly spring-loaded latch bolt will be moved to its outwardly extended position.
• lock bolt 14 can also be surrounded by a U- shaped element corresponding to the element 15 surrounding the latch bolt.
