the door lock and lockset manufacturing industry has overcome adverse conditions in recent years, largely stemming from increased international competition and offshoring through improved demand from key downstream markets. over the coming years, the industry will start to experience a slowdown in demand for its products as the pace of residential construction slows to a more stable pace. more organic growth in key downstream markets will still generate growing demand for industry products... purchase to read more .
the mortise lock takes its name from the fact that it requires a mortise – or a pocket – to be cut into the door or the object on which the lock is being fitted. mortise locks are not new, they have been around for an incredibly long time, and were used extensively before bored cylindrical locks were invented. in fact, the mortise lockset has come back into fashion in recent years, and it is now quite common in residential homes in the usa .
mortise locksets fit into a rectangular pocket that is cut into the door' s edge. they normally come with a deadbolt, which is part of the locking mechanism. when you turn the key from the outside it releases both the knob and the deadbolt. this is the securest lockset available. it comes in three styles that are pleasing for the décor: knob, lever, and handle. there are many different design options in each of these styles, all with easy use .
privacy lockset - the latchbolt is retracted by the grip on either side unless the outside grip is locked by the inside thumb - turn, button, or key. operating the inside grip unlocks the outside grip. an emergency release tool unlocks the outside grip. some manufacturers offer models that also unlock the outside grip when the door is closed (i. e. the door can only be locked from the inside if the door is fully closed - locking an open door then closing the door unlocks the outside grip) .
it’s a question most people don’t start thinking about, until they are in the lock hardware isle or standing in a locksmith shop. lots of times, people will use a term like “regular” or “standard” to describe the function of the lockset they are trying to purchase. unfortunately, manufacturers do not label their locks with those terms, leaving the consumer having to make a guess. well, let’s take the guess work out of it! here is some common industry knowledge and terminology to help make you a more informed consumer :
this grade offers a minimum level of security and durability. grade 3 locksets, also known as “standard duty” locksets, are made primarily for residential applications. bedrooms, bathrooms, closets, or any room that is not meant for public access but does not house expensive equipment or sensitive documents can be outfitted with this grade of lockset. grade 3 knobsets, for example, must withstand at least 200, 000 cycles, one set of blows at different foot pounds (i. e. two blows at 60 foot pounds), and a vertical load test of 150 pounds .
with reference now to the drawings, and particularly to fig. 1, there is shown and illustrated an amphi - latch for a tubular lockset constructed in accordance with the principles of the present invention. the latch portion consists of a latch case (1), two backset plates (2) and (5), a drive linkage (3), a drive unit (4), a slide extension (6) etc. , and the arrangement is coupled with a common type of lockset (7) as shown in fig. 3. the latch protrudes or retracts by rotating an outside or inside knob. the latch case (1) is coupled by means of the catches (23) of the backset plates (2 and 5) while the drive unit (4) of the latch case (1) is coupled with the connector (34) of drive linkage (3) which moves the drive unit (4). inside the backset plates (2 and 5) and drive linkage (3), slide holes (21 and 51) and slide slot (31) are provided for the sliding of a square - shaped drive unit (4) .
in a preferred embodiment of the present invention this simultaneous locking and unlocking is also accompanied by a panic proof feature that permits the unlocking of the lockset by a single twist of an inside hand operator. this version of the present invention employs a retractor coupled to the slide by biasing springs that urge the slide out of locking engagement with an actuator. the retractor is capable of longitudinal movement and is spring - biased towards the actuator. the turning of the inside hand operator effects translation of the retractor independent of the actuator to permit the movement of the slide out of locking engagement with the actuator and movement of the crank by the slide to an unlocked position .

the industry is known as a mature industry in that it is over 200 years old and changes come about slowly. terms used over a hundred years ago are still used today though not particularly applicable. one good example is
lockset
which years ago was
set locks
or
set lox”. it came about from the practice of selling the lock body and operating trim separately. hence, one bad to order a
set of locks
or the lock body, a spindle, a cylinder, a thumbturn, two operating knobs, two escutcheons, etc. to make up a complete set.' until about 40 years ago, architects, builders and code officials were not required to have much technical knowledge about builders hardware because very little in the way of codes, regulations or standards pertained to hardware .
the present invention has a deadbolt assembly and a spring latch bolt assembly to provide the security offered by the lockset. the deadbolt assembly includes means such as a crank rotatably mounted in the case for rotation upon retraction or extension of the deadbolt. the case mounts on the inside of a door. a slide in the case is acted upon by the crank during the locking of the deadbolt to move. the slide engages a latch actuator upon the locking of the deadbolt to lock the latch actuator against rotation. the actuator couples directly to the latch bolt assembly, and when engaged by the slide, prevents the latch bolt assembly from retracting. means bias the slide out of engagement with the actuator so that when the crank frees the slide, the slide moves out of engagement with the actuator to unlock the latch bolt assembly. this occurs when the deadbolt is unlocked .
6. an amphi - latch for a tubular lockset that is selectively adjustable to one of two positions by means of a drive unit having extensions adapted to engage one of two sets of lateral protruberances on a drive linkage, said drive unit and drive linkage being disposed between first and second backset plates and held in respective engagement by a slide extension, said slide extension having a u - shaped slot adapted to fit over said drive unit said slot being displaced to one side such that selective adjustment of said latch is achieved by repositioning said drive unit such that said extensions engage the other of said two sets of drive linkage protruberances and reversing said slide extension over said drive unit, said slide extension fitting between said drive linkage and said first backset plate in an outwardly displaced portion of said plate, said backset plates and drive linkage having elongated apertures to accommodate said drive unit in either one of the two positions .
a tubular lockset which includes a backset plate and a drive linkage, both of which are integrated within the rear portion of a latch case. the surface of the backset plate and drive linkage are set with slots and openings for the mounting of drive unit at the fore or rear position within the slots. two protrusions are provided on one end of the drive linkage, such that the foot of the drive unit engages with the protrusion of the drive linkage and drives the latch case forward and backward. an opening is provided on the drive linkage and slot is provided on each backset plate for the fixation of the drive unit, i. e. the drive unit is fixed within the slot of the backset plate and the opening of drive linkage. the backset length of the amphi - latch can be adjusted to either 60 mm (23 / 8
) or 70 mm (23 / 4
) .
a two - bolt lockset simultaneously locks and unlocks in response to a single action by an operator, such as a key and cylinder. a deadbolt couples to such an operator to project and lock or retract and unlock. a crank also responds to the locking of the deadbolt to move a slide that engages and locks an actuator of the second bolt, a latch bolt, to lock the latch bolt. the slide is biased away from the latch bolt so that upon retraction of the deadbolt and corresponding motion of the crank, the slide is freed of the crank and moves out of engagement with the actuator. preferably, the slide is carried by a retractor so that both locks clear by the single turn of a single inside operator. the retractor responds to a retractor cam attached to the inside operator to translate. the slide moves out of engagement with the actuator upon such movement and forces the crank to withdraw the deadbolt .
the characteristics of the present invention are that the front and rear portions of the slots of the backset plates (2 and 5) are provided with slide holes (21 and 51). there are three holes in each of the backset plates (2 and 5) and semi - circular holes (22 and 52) are provided at the end of each backset plate (2 and 5) for the selection of lockset (7) for coupling. furthermore, in one of the backset plates (5), the central region protrudes outwardly so as to form a space between the backset plates (2 and 5) such that the slide extension (6) can be inserted. protruberances (32 and 33) are provided on the central region and end respectively of drive linkage (3). the drive unit (4) is slidable mounted in the slide slot (31) of drive linkage (3). the feet (42) of drive unit (4) engage either the central or rear protruberances (32) or (33) of drive linkage (3). as a result, when the drive unit (4) is rotated, the drive linkage (3) can be moved inward or outward within the latch case (1). when the drive unit (4) is in the proper position, the slide extension (6) can be used to firmly secure the drive unit (4). the slide extension (6) has a u - shaped slot (61) thereon which is set off - center and recess (62) at one edge thereof. in addition, the semi - circular holes (22 and 52) are adapted to cooperate with the knob (7). the amphi - latch is set at the factory for a 23 / 8
( 60 mm) backset, and the feet of the drive unit (4) are engaged with hooks (32). the u - shaped slot (61) of slide extension (6) is on the right when viewed in fig. 1. the following are the procedures requested to adjust the latch from a 23 / 4
( 70 mm) backset :
