Referring to the drawings, and initially to
The electromagnetic device 10 includes a mounting plate 11 having one or more apertures 12 formed therein for receiving latches or fasteners (not shown) which may be used to attach or secure the mounting plate 11 to either of the supporting device 8, 88, and having one or more openings 13 formed therein for receiving one or more electrical wires or cables 14 which may be required to be engaged through the supporting device 8, 88, and having one or more screw holes 15 formed therein for receiving or engaging with a fastening means or device or one or more fasteners 20 which may be used to solidly secure a housing 30 to the mounting plate 11, in which the housing 30 is provided for receiving the typical electromagnetic members (not shown), such as the coils, the plungers, the solenoids or the like. One example of the typical electromagnetic members has been shown and disclosed in the applicant's prior U.S. Pat. No. 6,299,225 to Chang which may be taken as a reference for the present invention.
The mounting plate 11 includes two side channels 16 formed therein and each formed or defined by a flange 17, in which the flange 17 includes one or more notches 18 formed therein for forming or defining one or more ears 19. The housing 30 includes one or more passages 31 formed therein and aligned with the screw holes 15 of the mounting plate 11 for receiving the fasteners 20, and includes one or more orifices 32 formed therein and aligned with the openings 13 of the mounting plate 11 for receiving the electrical wires or cables 14. The housing 30 further includes two side rail ways or grooves 33 formed therein and each formed or defined by a rib 34 for slidably receiving the flanges 17 of the mounting plate 11 respectively, in which the rib 34 of the housing 30 includes one or more notches 35 formed therein for forming or defining one or more keys or pegs 36.
In operation or in assembling the mounting plate 11 and the housing 30, as shown in
Similarly or alternatively or relatively, the pegs 36 of the housing 30 may be engaged through the notches 18 of the mounting plate 11 and then engaged into the side channels 16 of the mounting plate 11 respectively in order to engage with the ears 19 of the mounting plate 11 when the mounting plate 11 is moved longitudinally relative to the housing 30 to allow the mounting plate 11 to be solidly and stably anchored and positioned to the housing 30. Similarly, the fasteners 20 may then be engaged through the passages 31 of the housing 30 and engaged with the screw holes 15 of the mounting plate 11 in order to solidly and stably secure and assemble the mounting plate 11 and the housing 30 together and to solidly and stably retain the ears 19 of the mounting plate 11 in engagement with the pegs 36 of the housing 30 and to prevent the ears 19 of the mounting plate 11 from being disengaged from the pegs 36 of the housing 30.
It is to be noted that the mounting plate 11 may first be solidly attached or secured to either of the supporting device 8, 88 with the latches or fasteners (not shown), and the engagement of the pegs 36 of the housing 30 through the notches 18 of the mounting plate 11 and with the ears 19 of the mounting plate 11, and the engagement of the ears 19 of the mounting plate 11 through the notches 35 of the housing 30 and with the pegs 36 of the housing 30 allow the mounting plate 11 to be moved longitudinally relative to the housing 30 for a relatively small distance or moving stroke, and thus allow the electrical wires or cables 14 to be suitably engaged through the orifices 32 of the housing 30 and the openings 13 of the mounting plate 11 while assembling or coupling the mounting plate 11 and the housing 30 together. In addition, the fastening of the mounting plate 11 to the housing 30 with the fasteners 20 allows the pegs 36 of the housing 30 to be solidly engaged with the ears 19 of the mounting plate 11.
Accordingly, the electrical lock device in accordance with the present invention includes an improved mounting structure for allowing the electrical wires or cables to be easily mounted or engaged through the electrical lock device and also for allowing the electrical lock device to be easily and quickly mounted or attached or secured to the supporting structures or members or devices.
Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
