Description

INTERIOR DOOR LOCK

FIELD OF THE INVENTION

The present invention relates to a lock for the interior of houses, hotels, apartments and other types of buildings, and more specifically to a lock that allows easy locking of the latch to the spring when reduced overall.

BACKGROUND OF THE INVENTION

A recessed lock for interiors of houses, hotels, apartments and other types of buildings generally includes an intrusion operated by a door handle on either side of the door and a latch operated by a key or cylindrical lock The locks are inserted in the recess at the edge of the door and include intrusions and latching that can be triggered (ie, moved away or pulled in) into a locking engagement with recesses formed in or out of the door leaf or frame.

In general, the recess, also known as the spring latch, has recessed interior locks located at least partially higher than the core lock. When moving the door handle, when the user pushes it down, the direction of movement of the core and the intake are the same. In the prior art, a simple piece of material, such as a lever, can be used to engage the latch by moving the core. Preferably similar types of locks used indoors not only provide light and quiet operation but are also simply built.

Spring locks and locking latches used in locks are available in various sizes that have evolved as relative industry standards. In particular, the hook and cylinder lock take on one of several relatively standard dimensions. Where it is desired that a similar type of lock be smaller, the intrusion involved in rotating the hook must be made of complex parts. The central length of the lock hook should preferably be in a position that is appropriate to the currently standardized lock dimensions. When the center length of the lock hook is maintained adequate with respect to the standardized dimension in the smaller lock, the lock inlet should be positioned lower than the core and closer to the latch. In this case, the direction of the incursion must be oriented in the opposite direction to the direction of the core of the lock. Therefore, when the size of the lock is reduced while maintaining the central length of the hook in a standardized ratio, a mechanism is required that easily catches the intrusion inside the body of the lock and is affordable at the same time. In addition, the position of the intrusion must also be changed according to the door where it will be used. A more practical way of changing the position of the intrusion will also make it easier to use by the user and the installer of the lock. There is no need to change the lock to make it suitable for doors that open inwards or outwards and in which only the knob and the knob reverses their position, the connection between the hook and the intrusion in this inverted position must be maintained.

The distance between the core of the lock and the pivot axis of the cylindrical lock, called the axial distance of the hook, is currently standardized in a particular country as well as in a wider geographical area. The position of the parts of the lock must be in a form that meets the aforementioned standardized lock measures. Recently, in order to save time and cost, it is desirable to use smaller recessed locks by reducing the area of the lock especially in manufactured wooden doors.

In addition, one of the goals is to save some material at the same time with a smaller lock, which contributes to the lower price of the lock. However, despite the reduction in the size of the lock, standardized measures must be followed, which results in the use of complex parts and increases the cost of the lock.

The object of the invention

The general object of the present invention is to provide an improved lock of the aforementioned general type that meets the above requirements.

The primary object of the invention is to provide a lock that is reduced by using a lever to facilitate intrusion and at the same time to maintain constant standardized dimensions of the lock.

It is a further object of the invention to provide a lock that reduces the force required to engage an incursion.

It is a further object of the invention to provide a lock that can easily be operated by the user where the intrusion is smoothly engaging and is not subjected to any additional resistance in the system due to optimum transmission force.

It is a further object of the invention to provide a lock that allows smaller pieces to be used with optimum locking transmitter force.

It is a further object of the invention to provide a lock that can be easily designed without the use of complex pieces, which contributes to the labor cost of making the lock.

It is a further object of the invention to provide a lock having durable parts using simple parts minimally exposed to shear forces.

It is a further object of the invention to provide a lock having holes for covering the door or rosette, although smaller.

It is a further object of the invention to provide a lock in which the position of the locking lock can be easily changed.

It is a further object of the invention to provide a lock having a snap mechanism which includes an improved mounting assembly for the left or right hand together with a simplified means of engagement.

Summary of the Invention

The present invention relates to a lock for use in the interior of schools or residential buildings. An internal door lock comprises a latch and a back of the core, a core rotatable by manipulating the hook, an intrusion and a rear of the intrusion that engages with the door frame and is located between the horizontal axis of the core and the latch. According to the invention, the lock further comprises a lever rotatable about the pivot lever hinge, which has a first lever associated with the lever and a second lever which is movable with the core tab when operated with the hook. In addition, the length of the second lever is equal to or longer than the length of the first lever, which contributes to the ease of intrusion.

According to the present invention, as shown in Figures 1a-1c, the inner door lock (10) comprises a retractable / retractable latch (16) and a rear part (17) of the latch that is pulled out or retracted in response to the rotation of the key (18); a core (20) rotatable with a hook; the recess (13) and the rear portion (25) of the recess which engages with the door frame and is located between the horizontal axis of the core (Yi) and the latch (16). The lock further comprises a lever (15) rotatable about the hinge (24) of the intrusion lever (13) having a first lever (50) connected to the inlet (13) and a second lever (60) driven by the tab (32) cores when the hook is moving. In addition, the length of the second lever (Z ₂ ) is equal to or longer than the length of the first lever (Zj).

In the prior art, spring locks, hereinafter referred to as inclines, locks used in the interior door are positioned higher than the core and closer to the upper part of the lock that engages inside the main body (19) by moving the hook. This is a problem when we want to make a smaller interior door lock while maintaining the standardized proportions of the door dimensions. As can be seen from Fig. 1a, according to the invention, in order to maintain the axial distance (E) of the crank corresponding to standardized dimensions, the inlet is positioned between the horizontal axis (Yi) of the core and the latch (16). In other words, in order to keep the axial distance (E) of the lever in a standard ratio, the incidence should be positioned in a lower position than the core with the reduced locks. Therefore, the intrusion of the lock (10) is positioned closer to the latch, which requires the use of a complex part to engage the main body (19) of the lock. When force is exerted on the lever that is shorter and the lever to pull the lever that is longer, then more force must be exerted than the force on the lever acting on the inlet. In this case, both the lever and the lever hinge are exposed to excessive load.

It is one of the object of the invention to provide a lock that will have a lever pull pull, which easily engages the blow and easily eliminates the need for its complex parts when the lock size is reduced. According to the invention, the lever (15) used to pull the incline is preferably used as a single piece. As can be seen from Figure 1, the lever (15) moves in synchrony with the recess (13) and the back (25), and the operation of the hook causes the core to rotate, which then enters the incursion into the main body (19). Referring to FIGS. 8a and 8b, the intrusion lever (15) is formed in the shape of a "V" with two different long arms, namely the first lever (50) and the second lever (60). According to a preferred embodiment of the invention, the length (Z ₂ ) of the second lever arm (15) is equal to or longer than the length (Z0 of the first lever arm) (15). , which has two different long arms.

Referring again to FIGS. 8a and 8b, the first lever (50) of the lever (15) comprises a convex edge (80) that allows an increase in the distance (X0) between the vertical axis of the point at which the core (32) of the core and the second lever (60) contact, and the hinge (24) of the lever when the recess (13) is drawn in. The tab (32) of the core is guided into the slot (40) for the core with a suitable wedge. lever forming a torque arm longer to achieve a balanced load distribution Referring to Figure 3a: when the core rotates to move the hook, the core tab (32) moves the second lever (60) of the lever having a convex edge ( 80), which causes the rotational movement of the lever (15). The force obtained is a single force and the related torque obtained by combining a system of forces and torques acting on a rigid body. ) appears as a vertical vector where the core tab (32) contacts the convex edge other arms (60) In Fig. 10, the resulting force is shown by its component forces such as tangential force (TF) and pulling force (D). Tangential force (TF) is a vector that serves to rotate the lever (15) about the axis of the hinge (24), and the pulling force is a vector facing the center of the hinge (24) and does not contribute to the rotation of the lever. In Figure 10a, the incident is in the extracted position, and in Figure 10A, the incident is in the drawn position, where scalar quantities are shown. When the incident is brought into the drawn position, as shown in Figure lOb, from the extracted position as shown in Figure lOa, the pulling force of the radial force is reduced and the tangential force is increased, which helps to make the incident easily drawn. Still referring to the figure 10aa, the distance (L1) between the housing (23) falls and the center of the hinge gradually decreases, and the distance (L2) is shorter than shown in figure 10b, which helps to optimally transfer forces due to different arm height lever (15). Due to the concave edge (90) of the first arm (50), the bulk force is exerted at right angles, which prevents the formation of scalar quantities, which represents resistance to the system. The housing (23) engages with the first lever (50) of the lever (15).

Another advantage of the invention is, as mentioned above, to provide a lock in which unnecessary resistance is reduced, as seen in the figures lOa and lOb, which helps the latch pin to guide the latch (15) in the slot (15). 71) does not place excessive stress on the lid. While operating the lock, the pin (70) of the intrusion guided in the recess slot (71) formed on the rear cover does not come into contact with the side faces of the recess slot (71) so that the level of friction to which the intrusion is exposed , reduced. The recess pin (70) is guided in the recess slot (71) formed on the back cover.

One end of the lever (15) is secured by the back of the recess (12). The lever (15) is pressurized by a spring (21) of the core, which is positioned higher than the core and can be moved by the core. The plate element is pressurized by the adjusting spring (22), which keeps the lock closed so that it fits into the corresponding tooth. The adjusting spring acts as a flat spring, the other end of the spring is in contact with the spring, which helps keep the door closed. Therefore, only one spring instead of two is present, which contributes to lower costs. The adjusting spring (22) rests on and presses the lever (15).

The main idea underlying the present invention, as can be seen from Figure 1, is that the horizontal axis (',' ₂ ) falls in a lower position than the horizontal axis (YJ cores. Therefore, a lock having smaller dimensions, Referring to Figure 1c, the latch (16) and the rear portion (17) of the latch are made in one piece by injection molding, but said piece may be used separately without the scope of the present invention, The corresponding door handle is securely secured to the core (20) when the core (20) is rotated; the lever (15) then rotates synchronously around the hinge. During the rotation, the recess is secured by the first lever arm (15). When the user pushes the door to close it, it enters the position, as shown in Figures 3a and 3b, and later moves into the recesses formed in the door leaf or frame.

Although the present invention relates to a lock having a conventional rear part of the lock which is activated by a key (18), it will be apparent to one skilled in the art that various locking mechanisms can be used to activate the latch. As an example, the locking mechanism can be used as a cylindrical lock or as a key lock with a beard. In addition, toilet-friendly locks can also be used with a core that is suitable for toilet-locks. In addition, the lever (15) of the invention may vary in structure and shape. Basically, the lever rotating about the axis of the hinge (24) may be affected by the rotation of the core, so that the difference in height of the lever arm helps the latch to be easily pulled in or out. The adjusting spring that preloads the lever is also used for the plate (30) mounted under the lever (15).

Another aspect of the present invention is to provide a lock that can be attached to different door types and sizes. An essential feature of this advantage is that said inlet can be rotated 180 ° and therefore easy to mount. As can be seen from Figure 4 and Figure 5, it is thus ensured that the connection tab (28) has a guide hole (29) for the connecting means (27). The connecting means (27) is preferably a screw, and the guide hole (29) has a through hole through which the screw is secured to fit into the plastic in the hole.

By means of the intrusion repositioning system (13), the connecting means (27), when the user wishes to change the intrusion position, can be reached through a circular hole (72) in the connecting means, as shown in Figures 5b and 4, to remove the connection between the intrusion and the back of the incursion. Again, with reference to Figures 5c and 5d: when the intrusion is released, the intrusion (13) is rotated 180 ° and then the insertion tab (28) is fully inserted into the housing at the rear (25) of the incidence. Thus, the hole formed at the rear of the recess (25) and the guide hole (29) of the recess tab (28) are aligned and the connecting means goes through.

Figures 6a and 6c show the position of the incidence in which it is fully absorbed. In this case, it is only partially visible through the connection element (27) in the upper upper cover (26) adjustment of the hole (72). In this case, the connecting means (27) loosens spontaneously even if the top cover (26) remains in place for this obstacle. Figures 6b and 6d show the intrusion (13) in the pre-change position, where it is pressed as far as possible with the finger and the connecting means (27) on the top cover (26), and a precise hole is reached around the hole (72). alignment. In this case, preferably with a screwdriver or similar tool, the appropriate coupling means (27) is removed and the change of position of the intrusion is effected.

Another advantage of the invention is to provide a lock having at least one screw hole extending from one end to the other end of the lock, which allows the door rosette to be attached to the door. With most such reduced locks, there is no such feature. If the screw holes run from one end to the other, different types of door rosettes can be used with the lock. It will be apparent to one of ordinary skill in the art that holes may be circular or any other polygonal shape.

The number of connecting means (27) and associated holes (72) of the upper lid connection means may be different and may be more than one. According to another embodiment of the present invention, the lock may be used for bathroom and toilet doors. In this case, a second core with a cylindrical lock may be present which is used to pull out / engage the latch.
