Description
This invention relates to motor actuated bell assemblies.
One prior art motor actuated bell assembly comprises a housing usually in the form of a box, and a motor actuated bell accommodated within the housing. The motor actuated bell generall~ comprises a base, a gong mounted on the base, and a motor actuated bell mechanism mounted on the base. The motor actuated bell mechanism includes an electric motor having a drive shaft, and a hammer operatively connected to the drive shaft of the motor for striking against the gong. The gong is connected to the base by a connecting means such as a C-shaped member. The ~ base is secured to a mounting plate which is secured to - the housing. Such a conventional motor actuated bell assembly has been found somewhat complicated in construction since a separate mounting plate is employed to mount ~he motor actuated bell within the housing. In addition, this has increased the material cost.
It is therefore an object of this invention to provide a motor actuated bell assembly which is simple in construction and assemblage.
In accordance with an aspect of the invention there is provided a motor actuated bell assembly comprising (a~ a housing box having a body with an open top and a lid for closing said open top; and (b) a motor actuated bell, said bell including a base formed with an integral support portion projecting from one surface thereof, a motor driven actuating mechanism mounted on said surface, and a cup-shaped gong mounted on the distal end of said support portion, said motor driven actuating mechanism including hammer means and being accommodated within said gong so that said hammer means is adapted to be brought into striking contact with the inner wall of said gong; Ic) .~
7~33 said motor actuated bell being mounted within said housing box, said base being fastened to said box body adjacent to said open top thereof and said motor actuated bell being accommodated within said box body.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 shows a motor actuated bell assembly 10 constructed in accordance with the present invention. The assembly 10 comprises a housing 11 in the form of a box and a motor actuated bell 12. As shown in FI~S. 2 and 3, the motor actuated bell 12 comprises a rectangular base 13 and a bell mechanism 14 mounted on the base. The bell mechanism includes an electric motor 15 having a drive shaft 15a, a cam 16 fi~edly mounted on the drive shaft 15a for rotation therewith, and a hammer means 17 on which the cam 16 acts to move a hammer into striking contact with a gong 18 to produce a bell sound. The hammer means 17 includes a leaf spring 17a and a hammer element 17b attached to one end of the leaf spring 17a. The motor 15 and the hammer means 17 are mounted on a support member 19. The support member has a rectangular planar base ~ .
~ - 2 -portion l9a and a pair of arms 1sb, l9c extending perpendicularly from the base portion l9a at its lateral edges. The support member 19 is secured to the base 13 by bolts l9d and nuts l9e. The motor 15 is secured to the arm l9b by screws 20, and the leaf spring 17a is secured to the arm l9c at its end remote from the hammer element 17b. While the motor actuated bell mechanism 14 of the type described is used in-this embodiment, any other type of bell mechanism may be employed.
10The base 13 is made of a thin metal sheet and has a central gong support portion 13a in the form of a hollow projection of a truncated cone-shape. As best shown in FIG. 3, the motor actuated bell mechanism 14 is mounted on the surface of the base 13 on which the projection 13a is formed. The inner central portion of the cup-shaped gong 18 is mated with and secured to the top wall 13b of the truncated cone-shaped projection 13a by a bolt 23.
A plurality of indented formations 13c are formed on - the base 13. The indented-formations are drawn out of the plane of the base 13 away from the projection 13. As best shown in FIG. 2, each indented formation 13c is provided at the area adjacent to a slit 13d. In the illustrated embodiment, the indented formations 13c are disposed along the axis of the base 13, and three indented formations 13c are provided on each side of the projection 13a. The base 13 has screw holes 21 formed through its peripheral margine.
The housing box 11 is made of metal and has a body lla with an open top and a closed bottom and a lid llb hinged to the body for closing the open top. A plurality of indented formations llc are also formed on the lid llb, as described above for the base 13. The body lla is so sized that the base 13 is fitted in the body. The housing body lla has tabs (not shown) adjacent to its peripheral edge defining the open top of the box body The tabs are disposed in registry with the respective screw holes 21 when the base 13 is installed in place in the housing box 11 .
For installing the motor actuated bell 12 in the housing box 11 to provide the motor actuated bell assembly 10, the base 13 is fitted in the housing body lla upside down, that is to say, with the motor actuated bell 12 and the pro~ection 13a being accommodated within the box body lla. In this condition, the screw holes 21 are disposed in alignment with the tabs of the box body lla. The base 13 is fastenedjto the box body lla by screws 21a passing - through the respective aligned screw holes 21 and tabs.
The lid llb is then closed and fastened to the body lla by a suitable fastening means (not shown).
With this construction, the motor actuated bell assembly 10 obviates the need for a mounting plate for mounting the motor actuated bell 12 within the housing box 11. More specifically, the base 13 is of such a construction that it is directly mounted onto the housing box 11.
According to a modified form of the invention shown in FIGS. 4 and 5, a base 25 has a central gong support portion 25a of a trapezoidal cross-section. The support portion 25a comprises an elongated rectangular metal plate which is pressed into a trapezoidal cross-section having a pair of arms 25b and a top wall 25c interconnecting the arms at their ends, the support portion having a pair of 7~33 flanges 25d. As best shown in FIG. 5, the inner central portion of the cup-shaped gong 18 i~ mated with and secured to the top wall 25c of the support portion 25a by a bolt 23. The pair of flanges 25d is fixedly secured to the base 25 by spot welding. The support portion 25a is disposed at the center of the base 25. A plurality of indented formations 13c are formed on the base 25, as described above for the base 13. The base 25 is fitted in and secured to the box body lla in the manner as described above for the base 13.
By virtue of the provision of the base 13, 25, the motor actuated bell 12 can be mounted on the housing box 11 with utmost ease.
While the motor actuated bell assemblies according to the invention h~ave been specifically shown and described herein, the invention itself is not to be restricted by the description thereof.
