       [0001]     The patent application is a continuation-in-part of application Ser. No. 10/746,771 filed Dec. 23, 2003, Title Cabinet door system, which is already in publication, and application Ser. No. 10/917,607 filed Aug. 13, 2004, Title; Cabinet door locking system which is incorporated by reference herein its entry for all purposes 
     
    
     BACKGROUND  
       [0002]     Some interior doors may utilize a lock with knob or other similar method to secure the door in the closed position. However, these types of securing configurations may not typically be used for cabinet doors and drawers, like the ones in Kitchen. Such cabinet doors and drawers may be kept closed without any locking system.  
         [0003]     These configurations may not operate satisfactorily when intending to keep children away from content of cabinet and drawers. Also, during an earthquake or other events, the contents of the cabinet may fall out or drawers may slip out.  
         [0004]     What is needed is a securing configuration that will allow the door and drawers to remain secured to the cabinet until unsecured by a user.  
       SUMMARY  
       [0005]     Provided are exemplary embodiments that may include a cabinet door and drawer securing system, including a sliding wedge, coupled to a coil spring, a shaft coupled to a cam, a knob coupled to the shaft, a clad housing with a cover. With this configuration, when the door is closed by any means, could not be opened, and the drawer if be pushed in could not be pulled out unless activated by adult.

     DETAILED DESCRIPTION  
       [0023]     The detailed description set forth below in connection with the appended drawings is intended as a description of exemplary embodiments and is not intended to represent the only forms in which the embodiments may be constructed and/or utilized.  
         [0024]     The description also sets forth the functions and the sequence of steps for constructing and operating the invention in connection with the illustrated embodiments. However, it is to be understood that the same or equivalent functions and sequences may be accomplished by different embodiments that is also intended to be encompassed within the spirit and scope of the invention. As example instead of turning knob, a push button may be used.  
         [0025]     A cabinet door and drawer securing system  10 , according to an exemplary embodiment is shown in  FIG. 1 , in an unactuated position. The cover  26 , removed to show inside clad  24 . The wedge  12 , which has an oblique plane head on one side of its top and a straight plane in its behind. The wedge  12 , has a coil-spring  20 , inserted in its spring housing  21 , under the wedge chamber  13 . The shaft  16  passes through wedge chamber  13 , and is coupled to the key-hole-cam  14 , when the knob  18 , which is coupled to the shaft, and tightened by its screw  40 , is turned, hence the shaft and cam turns and pushes the wedge down.  
         [0026]      FIG. 1 , furthermore shows the folded corners  30 , for holding the cover  24 , there it shows also the two positional adjusting slotted holes  28 .  
         [0027]      FIG. 2 , is the front view of cover  26  for clad  24 . With the two slotted holes  28 , and shaft hole  27 .  
         [0028]      FIG. 3  is the cabinet door and drawer locking system in an actuated position. The cover  26  removed, The wedge  12  has gone down, because the cam has been turned by the shaft  16 , and knob  18 , hence the wedge  12  has hit to the bottom, away from wedge stop-plates  32 . Hence, the wedge head cannot be in the way of system holding-bracket  46  any more.  
         [0029]      FIG. 4  is the back of the locking system  10 ; it is equipped with a facility, to adjust for desired knob turning tension. A turnable-lever  38 , is coupled freely to the end of the shaft  16 , and a key-hole-lever  36 , fastened on the end of the shaft  16 , tightened with nut  34 . The turnable-lever  38 , which is coupled to key-hole-lever  36 , by a coil-spring  22 , pulls up key-hole-lever  36 , toward stop-pin  43 , keeping the key-hole-cam toward its upright position.  
         [0030]     Turnable-lever  38  could be positioned behind the low-pin  41 , for normal users, or for higher knob turning tension, behind high-pin  42 , where the knob needs more tension to be turned, which would be difficult for small children to open the lock.  
         [0031]      FIG. 5 . is prospective view of the clad  24 , with slotted holes  28 , folded corners  30 , and shaft hole  37 .  
         [0032]      FIG. 6 . is the oblique-headed wedge  12  and straight plane back, with wedge chamber  13 , coil-spring  20 , in its spring-housing  21 .  
         [0033]      FIG. 7 . is the wedge  12 , with oblique floor in its wedge chamber here instead of key-hole-cam and turnable shaft, an oblique-bottom cam  44 , fitting only ⅓ length to the bottom floor, and push button  45  is been used to push in for lowering the wedge.  
         [0034]      FIG. 8 . is the elevated view of the fastening nut  34  for key-hole-lever  36 .  
         [0035]      FIG. 9 . is the elevated view of the key-hole-lever  36 , and turnable-lever  38 .  
         [0036]      FIG. 10 . is the elevated view of the key-hole-cam  14 .  
         [0037]      FIG. 11 . is the elevated view of the shaft, with key planes and threaded screw on both ends.  
         [0038]      FIG. 12 . is the elevated view of knob  18 , and its tightening screw  40 .  
         [0039]      FIG. 13 . is the perspective view of locking system installed on a drawer  7  for a deck or counter  6 .  
         [0040]      FIG. 14 . is the elevated view of system holding-bracket  46 , with its slotted holes  39  on the plate and screws  29 .  
         [0041]      FIG. 15 . is the elevated view of oblique-bottom-cam  44 , with its tightening screw  40  and Push shaft hole  51 .  
         [0042]      FIG. 16 . is the elevated view of push shaft pressure adjusting facility, with spring plate  48 , pressure adjusting screw  49 , slotted-hole  50   
         [0043]      FIG. 17 . is the prospective view of, locking system installed on a cabinet door  9 , with its fastening screws  29 , in positionally adjusted by its slotted holes  28 . Here the turnable-lever  38  is positioned behind the low-pin  41  for normal users.  
         [0044]     In  FIG. 17 , on the opposite side is the system holding-bracket  46 , fixed and tightened on the interior of cabinet sidewall with the positional adjusting slotted holes  39 , and screws  29 .  
         [0045]     Most of the locking system parts, may be made with plastic injection, or cast from metal. The wedge may be made even from wood. The clad pressed from sheet metal, rubber, any combination thereof, or other materials, as desired. Similarly, the other portions of the system may be made from other suitable materials. It will be appreciated that other configurations and devices may be used to create the same movements and configurations, as desired.  
         [0046]     Although screw or bolt has been shown, it will be appreciated that other fastening configurations and methods may be utilized including nails, adhesives, and other configurations and methods, as could be convenient for manufacturers or users.  
         [0047]     This system is usable with a wide variety of existing and new cabinet systems.  
         [0048]     As generally depicted in  FIGS. 13 and 16 , when the cabinet drawer  7 , or door  9 , is pushed to closed by a slight force, or some self-closing configuration, the wedge  12  may advance by rubbing the two oblique surfaces, one on holding-bracket  46 , and the other on the wedge,  12  oblique head. The horizontal force, partly will transfer to vertical force, pushing the wedge down in the clad  24 , to clear the way of holding-bracket  46 , then the wedge will jump up due to the force of coil-spring  20 , remaining behind holding-bracket  46  straight plane, where the door or drawer can not be pulled back and will remain locked.  
         [0049]     Not any force can open it just by pulling the knob, and the system will remain secured unless a user, an adult or other source of force turns the knob  18 , or pushes the push button  45 , which lowers the wedge head, there after nothing will prevent the door or drawer from opening.  
         [0050]     In closing it is to be understood that the exemplary embodiments described herein are illustrative of the principles of the present disclosure. Other modifications that may be employed are within the scope of the disclosure. There is no limitation; alternative configurations may be utilized in accordance with the teachings herein. Accordingly, the drawings and description are illustrative and not meant to be a limitation thereof.
