Description

[Detailed description of the invention] The present invention relates to a lock that can be operated by a key.

A conventional lock consists of a lock barrel rotatably received within the lock body. Ru. This locking bolt has a spring loaded pin. This lock has a spring negative Operated by a key with a key blade having a profile that cooperates with a loaded pin be able to. Some locks have been shown to work when the pins are properly placed. The lock barrel can be rotated to the unlocked position by moving radially inward. Includes a locking bar or side bar.

These conventional locks are prone to tampering and are relatively easy to tamper with. You can "pry it open."

In addition, the number of possible combinations is limited. This lock barrel is complicated structure and therefore expensive to manufacture, repair or modify. , it is necessary for locksmiths to keep a huge number of parts in stock.

It is an object of the invention to obviate or reduce some or all of the above-mentioned disadvantages. The aim is to substantially reduce both.

Accordingly, the present invention, in one aspect, can be actuated by a key and In a lock barrel assembly that is now received within a hollow lock body. , the lock barrel assembly includes a hollow base having a longitudinal axis; rotatably supported within the axis and extending generally perpendicular to the axis. and a disk, the or each disk having a key for passing the key therethrough. an opening for the disk or the like, the key being adjacent to the opening; so that each disc can be placed in a predetermined position about the longitudinal axis. a key engaging means adapted to engage the key, and the or each disk. the discs, and the or each disc is Longitudinal from outer position to inner position only when keyed into its predetermined position at least one locking bar adapted to move radially relative to the direction axis; Provides a lock barrel assembly.

In another aspect, the invention provides a key for actuating a lock barrel assembly. at least one longitudinal section adapted to receive keying means; A key having an angled trajectory is provided.

Hollow lock body capable of receiving the lock barrel assembly of the present invention therein includes a combined lock barrel assembly and hollow lock body, among other things Can be used as , cylinder lock, cam lock, furniture lock or padlock As such, you can choose from a wide range. Lock barrel assembly of the present invention provides a wide range of locking functions by simply changing the selection of the hollow lock body. be able to.

Inside the hollow lock body when the lock barrel assembly of the present invention is in the closed state. and move the or each locking bar to an inward position. It is possible to rotate the lock barrel assembly by is preferred.

The number of disks in the assembly can determine the range of possible combinations. Wear. Preferably, two or more discs are used. easy to explain In order to achieve this, we will explain the case of multiple disks.

However, the present invention can be operated with only one disk. should be understood.

It is convenient if an opening for passing the key is placed in the center of each disc. .

The keying means may be configured in any suitable form. The key engagement means is disabled. Preferably, it has one or more protrusions extending into the opening of the screen. Delicious.

For economy, only one locking bar is provided within the lock barrel assembly of the present invention. It's convenient if you can. Nature of the functional connection between the locking rod and the disc may be changed, but each disc may have a locking bar slot, groove, hole or similar It preferably includes a protrusion, i.e. a pin, adapted to be received in the opening. stomach.

In one particularly preferred embodiment, both the locking bar and the key are Cut according to the same "code" supplied by the software. however , for maintenance, the physical correlation between the locking rod and the key should be placed side by side. Even the names should be so different that they are clearly not similar. Di Scramble is a means of movement that connects the lock rod and the key. mbling) means to ensure that there is no physical resemblance. Can be done. The key is inserted into the lock barrel assembly and the key locks the disc into it. The disc originally picks up the "code" from the key when it is aligned in place. Ru. This "code" is coded even if the physical shape of the locking rod differs from the physical shape of the key Even if it is, it will be transferred to the locking rod as it is.

A disk lock washer is optionally included within the lock barrel assembly of the present invention. Unlike discs that are rotatably supported within a hollow base, this The washer rotates with the entire assembly as the locking bar moves to the unlocked position. It can be kept in a restrained state until it is possible to do so.

This washer acts as a guide for the key and directs the rotation of the key throughout the assembly. an opening preferably having the same contour as the key contour so that it can be transmitted to It is equipped with Multiple washers can be included in the assembly if desired. Ru. These washers also prevent "pry-opening" as explained further below. It can have eyelets to help.

The disk is rotatably supported within the base, as described above. In particular, If gold is included, the angle supporting the arc of rotation of the disc will be If so, it can be restricted.

In one particularly preferred embodiment, the lock barrel assemblies are arranged in five sets. It has 10 disks. Between each set of discs is a key ring. A washer is provided having an opening in the shell. The combination of disc and washer is Conveniently held in place by a case-hardened plug that includes a key-contoured opening It will be done. (This plug also works to prevent drilling of the lock barrel assembly. I can do business. ) This example has strength and tremendous strength, as explained below. To provide a lock assembly having both a large number of combinations and a large number of combinations.

In this embodiment, the keying means each have a rotation angle limited to 36°. It has a protrusion, or pin, on the disk. Protrusions on each disc The predetermined positions that can be occupied are each at intervals of 6° within an arc of 36°. You can choose from seven possibilities. Since 10 disks are used, More than 280 million combinations are obtained. In addition, the disk The protrusion on the disc (closest to the plug) can be placed on the right or left side. It can be loaded as shown. This doubles the number of combinations obtained. Ru.

The key of the invention can have a circular cross-section or any desired shape, e.g. , the cross section of the key can be removed to form it in the shape of a keyhole. of the key One suitable material is nickel-silver. Above this is the lock assembly. It has a key blade to activate it and a key head to prevent the key from being pressed. child The remainder of the description will refer to the keyblade as the actuating part of the key. I'll decide.

The key blade is cut from the cylinder so that its cross section resembles the shape of the keyhole, If the cross-section of the cylinder is removed, the top of the cross-sectional profile is preferably 1 in the range of 400 to 160°, and the blade diameter ranges from 7 to 8 discs It's within. The blade continues on the second lead to the point where all cuts begin or end. It can have a pointed apex with an angle.

The keyblade preferably has a trajectory with a programmed angle, i.e. , slots can be machined.

In this embodiment, the key cutting is a track, i.e., a slot in the cylindrical part. Including machining.

This raceway is drilled using a specially manufactured disposable slot drill with a chamfered cutting edge. It can be cut by cutting. This trajectory is cut longitudinally into the keyblade and The angle changes radially as you move forward. The cutter is always a keyblade. It should be directed towards the center.

The cut keyblade may be characterized by having more than one track. can.

For example, two tracks can be provided, each aligned with one half of the disk. It has become so. The first trajectory starts at the tip of the key and - Change direction 10 times to reach the end of the blade.

This trajectory may terminate at the end of the keyblade or extend beyond the apex of the keyblade. may extend to form a second track extending back to the tip of the key, as well as , changes direction 12 times before terminating at the tip of the key.

key engagement means when the key blade enters the lock barrel assembly of the present invention; For example, the protrusions within each disc opening can be into orbit, and the disk rotates accordingly. Orbit on the keyblade The location, number of turns and routes as well as the number of trajectories per keyblade vary. can be modified, resulting in a very large number of possible key contours.

The key of the present invention does not contain any sharp points or protrusions, and therefore many existing keys - Made in such a way that it will not scratch or cut clothing as in the case of It should be noted that it is possible to build

The locking bar has two positions, as described above.

In the first or outer position, the locking bar preferably has a hollow lock body. It is held in the body groove and cannot be opened while the locking bar is in this position. I can't.

The locking rod is held in this position by an external protrusion, or pin, on the disc. It will be done.

The disc will rotate when the correct key is inserted into the lock barrel assembly. This allows the outer protrusion, i.e. the pin, to fit into the slot, slot or hole of the locking bar. or similar opening. By turning the key, the locking rod can be turned into a hollow lock. Pushed from that groove in the body, the protrusion, or focus, engages. Therefore, Ro The lock barrel assembly can be rotated and unlocked.

The protrusion, i.e. the pin, engages with a slot, groove or hole in the locking bar. Insert the key into the lock bar assembly until the lock bar is inserted back into the groove in the hollow lock body. cannot be withdrawn from The spring biases the locking bar to the outer position and A locking rod that falls into a groove when the spring-loaded locking rod is aligned with the groove. This indicates successive rotational positions of the key. When the key is retracted, the key is the " "Scramble".

The locking rod is conveniently manufactured from brass or nickel-silver and is It can have radially extending slots or grooves. As another aspect, As already mentioned, a hole can be drilled into the locking rod.

Preferably, each hole is a drilled blind hole.

There are also typically three or four extra shallower holes per locking rod to prevent pry-outs. It is further preferable that the material be rubbed as a feature to prevent scratches. These shallow holes It cannot engage with the protrusion of the disc.

If desired, the locking bar can have a mixture of slots, grooves and/or holes. can.

In the case of a master locking system, the locking bar has a number of actuable slots, grooves, and/or holes.

It will be appreciated that the locking bar is an important feature of the invention. This locking rod is of the present invention. Provides a high degree of flexibility in locking and security.

In addition, the use of a locking bar instead of a key pin in the case of prior art locks This allows changes to be made quickly and economically. i.e. a new key and even replace the old locking rod with a new locking rod. do it. A skilled locksmith is required to change the combination of conventional locks. In the case of the lock barrel assembly of the present invention, an ordinary handyman is required. could replace the locking bar.

If desired, a locking bar groove, slot or hole cord may be used, e.g. Lock barrel assembly for each locking bar to avoid observation with help may include a lid plate.

Examples of preferred embodiments of the invention will now be described with reference to the accompanying drawings.

Lock barrel assembly 10 has a generally cylindrical configuration and a base portion Contains 16. The base portion 16 has a C-shaped cross section and has a It has an outer surface that slidably engages the surface. Between the arms of the base part 16, A locking rod 27 is arranged. The locking rod 27 is in the groove 1 in the chained position. Accept within 4 days. A spring 23 biases the locking bar 27 to an outer position.

Five sets of discs 17 spaced apart by washers 18 are slidable within the base portion 16. It is stored in Noh. Each disc 17 is arranged such that it forms a central passage 19. It has a shape similar to the thyroid line. The washer 18 also has a thyroid-like shape, A passage 2o is formed. Disc 17 and washer 18 are lock barrel a It extends generally transversely to the longitudinal axis 28 of the assembly 10. aisle 2 0 has a shape that generally matches the cross-sectional shape of the key blade 11.

An engagement protrusion 21 projects into each passageway 19 . The engagement protrusion 21 is a key to be received within the slot of the blade 11, i.e. the track 22. There is.

The radial outer peripheral surface of each disk 17 is provided with a protrusion 24 . Projection 24 is adapted to be received within a hole 25 formed in locking bar 27. Also, When the key blade 11 is rotated, the disk 17 and washer 18 are , a complementary portion of the base portion 16 to aid in rotation of the lock barrel assembly 1o. A protrusion 26 is further provided for engaging the surface. Plug 12 and circular clit A cap 13 serves to secure the lock barrel assembly 1o.

To activate the above lock, when the key blade 11 is inserted, the disk The protrusion 21 of the lock 17 engages with the track 22, and the key blade 11 locks into the lock bar. longitudinally of lock barrel assembly 10 as it advances into barrel assembly 13. It is oriented at an angle with respect to the adaxial axis 28. Keyblade 11 is fully inserted The projections 24 are then radially aligned with the holes 25. This is groove 1 4 (see FIGS. 4A to 4), the half of the locking bar 27 Allows for radial inward movement.

Therefore, when the key blade 11 is rotated, the lock barrel assembly 10 also Also, when the locking rod 27, which is now movable inward in the radial direction, passes through the groove 14, , rotate.

If the key blade 11 does not have the slot 22 of the correct shape, the protrusion Since portion 24 is not aligned with hole 25, locking bar 27 may move radially inward. is prevented. Therefore, the protrusion 24 collides with the inner surface of the locking rod 27, and the locking rod 27 from moving radially inward. Therefore, the locking rod 27 is in the groove 14. rotation of the lock barrel assembly 10 is prevented.
