DETAILED DESCRIPTION
(17) A cabinet 1 with a cabinet door locking device 2 and a cabinet drawer locking device 3, in accordance with the present disclosure, is shown in in FIG. 1. The cabinet door locking device 2 and cabinet drawer locking device 3 are the analogous locking devices. The cabinet 1 comprises a cabinet door locking device 2, a cabinet drawer locking device 3, a cabinet front wall (panel) 4, a cabinet door 5, a cabinet drawer 6, a cabinet drawer front panel (wall) 7, a cabinet shelf 8, a cabinet door first hinge 9 and a cabinet door second hinge 10 in order to provide the cabinet door 5 swinging (pivotable) movements, a cabinet door handle 11, a cabinet drawer handle 12, a plate 13 and a cabinet base 18. The plates 13, conventionally shown in FIG. 1, are intended to protect a cabinet door outer (front) surface 14 or the cabinet drawer outer (front) surface 33 (which could be molded or painted) from the possible scratches or other damages made by the locking member head 15 (shown in FIGS. 7A, 7B and 8) of the locking member 16 during locking-unlocking operations. It is understandable, that cabinet door locking device 2 and the cabinet drawer locking device 3 can be identical or can have different configurations, shapes (forms), sizes, etc.
(18) FIG. 2 illustrates the cabinet 1 without the cabinet door 5 and without the first 9 and second 10 hinges and plate 13 on the drawer outer surface 33. In FIG. 2, the plate 13 is conventionally not shown in order to demonstrate that the plates can be not installed on the cabinet doors and/or drawers, as it can be found in the all prior art patents briefly described hereinabove in the background chapter. As shown in FIG. 2, the cabinet front panel 4 of the cabinet 1 comprises a cabinet door opening 17.
(19) FIG. 3 illustrates a screw bushing 19. According to this front view, the screw bushing 19 comprises an outer thread 20 (a screw busing outer thread 20), an inner thread 22 (a screw busing inner thread 22), and spline 21, which are also shown in FIGS. 4, 5, 6 and 8.
(20) FIG. 7A depicts the locking member 16, which in addition to the locking member head 15 also includes an extended portion 23 which comprises an outer thread 24 (an extended portion outer thread 24). The locking member 16 is conventionally presented in FIGS. 7A-7C and 8 as a solid piece (entire element having two non-separate portions: the extended portion 23 and locking member head 15), but the locking member 16 can comprise at least two separate portions (not shown): a portion of the locking member head 15 and a separate extended portion 23 (e.g., such as a boltnot shown) rigidly attached to that locking member head 15. The thickness of the locking member head 15 can be the same as the diameter of the extended portion 23, or the locking member head 15 can have the reasonably less thickness (not shown), and the presented drawings do not and should not limit the thickness of the locking member head 15 [for example, the thickness of the locking member head 15 can be bigger (not shown) than the diameter (including outer thread 24) of the extended portion 23]. The locking member head 15 can have any reasonably convenient thickness, as well as the configuration, shape and form, for example, according to FIGS. 7A-7C. The one of many possible cross-sections of the locking member head 15 is shown in FIG. 7C, wherein the locking member head 15 is presented as of a circular configuration, and the cross-section of the locking member head 15 can be not only of the circular configuration, as shown in FIG. 7D, but also of a flat configuration (not shown), etc. The FIG. 7B depicts the locking member head 15, wherein the lower edge of the head 15 has a rounded configuration.
(21) The screw bushing 19 can be inserted (screwed) into the cabinet base 18 in any conveniently selected place in the area of the opening edge 25 of the cabinet door opening 17. The screw bushing 19 insertion (installation) at selected place is provided by drilling the aperture 26 in the cabinet base 18 near the opening edge 25. Using a flat screwdriver (not shown) and spline 21, the screw bushing 19 is screwed inside the aperture 26. Referring to FIG. 8, the diameter of aperture 26 should be accordingly corresponding to the outer thread 24 of the extended portion 23 of the locking member 16. The locking member 16 by its outer thread 24 of the extended portion 23 is coupled with the inner thread 22 of the screw bushing 19. The tightness of the closed position of the cabinet door 5 to the cabinet base 18 can be provided by the tighter screwing of the locking member 16 into screw bushing 19.
(22) Some cabinets use one door opening 17 for two cabinet doors: a first cabinet door 27 and a second cabinet door 28, for example as it is shown in FIG. 9. In FIG. 9 are conditionally presented the cabinet door locking device 2 in the position when the first cabinet door 27 and a second cabinet door 28 are closed, and a single cabinet door locking device 2 locks both (first 27 and a second 28) cabinet doors. It is understandable, that the first cabinet door 27 and the second cabinet door 28 can have a separate own cabinet locking device 2. The cabinet drawer locking device 3 is conditionally shown in FIG. 9 as in the unlocking position. The plates 13 and hinges are conditionally not shown in FIG. 9. Again, it should be understandable, that all cabinet door locking devices and the cabinet drawer locking devices can be identical or each can have the different configurations, shapes (forms), sizes, etc.
(23) Such cabinets usually include a vertical cross bar 29, as it is shown in FIG. 10. For such cabinets, comprising the vertical cross bar 29, the aperture 26 can be drilled in the vertical cross bar 29 and the screw busing 19 can be inserted (installed) in that aperture 29. A first projection 30 of the locking member head 15 and a second projection 31 of the locking member head 15 (FIG. 8) can be appropriately use for keeping the first 27 and second 28 cabinet doors in the doors' closed positions (FIG. 9). If the use of only one cabinet door locking device 2 for both (first 27 and second 28) doors is not convenient, than two locking devices can be used (not shown): one lock
(24) for the first door 27 and another lock for the second door 28. If the cabinet does not include the vertical cross bar 29, than the screw busing 19 can be installed in the front edge (panel) 32 of the cabinet shelf 8, as it is shown in FIG. 11, and the first projection 30 and a second projection 31 of the locking member head 15 can be appropriately used for keeping the first 27 and second 28 doors in the cabinet doors' closed positions, as it is shown in FIG. 9. Also, the cabinet locking device for the first 27 and second 28 cabinet doors can be installed (not shown) in the cabinet base 18 in the areas, for example, of the upper or lower edges (not shown) of the first 27 and second 28 doors.
(25) The locking member head 15 can comprise a single projection (not shown) instead of two projections: the first 30 and second 31 projections, as shown in FIGS. 7A, 7B and 8). The locking king member head 15 can be of the circular form, as it is shown in FIG. 7C, with the circular cross-section, as shown in FIG. 7D.
(26) For locking of the cabinet door 5 in the door closed position, the person (operator) rotate the locking member head 15 to the position when the locking member head 15 is in the horizontal position (not shown), and the first projection 30 of locking member head 15 or the second projection 31 of the locking member head 15 is located over the plate 13. The tightness of the cabinet door 5 closed position can be controlled (regulated) by the tightness of the resting of the locking member head 15 on the plate 13.
(27) For locking of the cabinet drawer 6 in the cabinet drawer closed position, The screw bushing 19 can be inserted (screwed) into the cabinet base 18 in any conveniently selected place in the area of the opening edge (not shown) of the cabinet drawer opening (not shown). The screw bushing 19 insertion (installation) at selected place is provided by drilling the aperture 26 in the cabinet base 18 near the opening edge (not shown) of the cabinet drawer opening (not shown). Using a flat screwdriver (not shown) and spline 21, the screw bushing 19 is screwed inside the aperture 26. Referring to FIG. 8, the diameter of aperture 26 should be accordingly corresponding to the outer thread 24 of the extended portion 23 of the locking member 16. The locking member 16 by its outer thread 24 of the extended portion 23 is coupled with the inner thread 22 of the screw bushing 19. The tightness of the closed position of the cabinet drawer 6 to the cabinet base 18 can be provided by the tighter screwing of the locking member 16 into screw bushing 19.
(28) For locking of the cabinet drawer 6 in the drawer closed position, the person (operator) rotate the locking member head 15 to the position when the locking member head 15 is in the vertical position, as it is shown in FIG. 1, and the first projection 30 of locking member head 15 or the second projection 31 of the locking member head 15 is located over the plate 13.
(29) It is understandable, that the threads can be left-hand or right-hand (regular). In FIG. 7A is conditionally (as example) shown the outer thread 24 of the extended portion 23 as a left-hand thread 33, but in FIG. 3 the outer thread 20 of the screw bushing 19 is conditionally (as example) shown as a right-hand thread 34. It is also understandable that if, for example, the outer thread 24 of the extended portion 23 is the left-hand thread, than the inner thread 22 of the screw bushing 19 should be the left-hand thread too.
(30) The padlock can be easily used through the opening (hole) in the head 15 of the locking member 16 and cabinet butt (not shown) additionally installed near the locking member 16.
(31) There are many advantages of the improved cabinet locking device, one of which is: the improved cabinet locking device does not include any sprigs, which require the use of the resiliently compressible-pullable manual actions, which may be not conveniently possible for the elderly or ill persons, and the improved cabinet locking device is configured also to successfully work with the cabinet doors intended to lie flush with a cabinet base (not shown).
