## Background
BACKGROUND OF THE INVENTION
(1) Field of the Invention
The present invention relates to a percussion device, especially to a chime bar assembly with a hitting device connected with the hollow body.
(2) Background of the Invention
A conventional chime bar assembly generally includes a hollow body with two open ends which are sealed by a front cover and a rear cover so as to form a resonation space in the hollow body. The hollow body includes a top opening and a metal plate is located above the top opening so that the user hits the metal plate by a stick and the sound is resonated within the hollow body to generate a specific sound. However, the users spend a lot of time to find the stick because the stick is an individual part from the hollow body and often put randomly. Besides, the operation is boring by holding the stick to hit the metal plate.
The present invention intends to provide a chime bar assembly with a hitting device connected to the hollow body, the hitting device can be operated by different ways to hit the metal plate to generate the sound.
SUMMARY OF THE INVENTION
The present invention relates to a chime bar assembly and comprises a hollow body including a resonation space defined therein, the hollow body including a front opening, a rear opening and a top opening. A front cover seals the front opening of the hollow body and a rear box seals the rear opening of the hollow body. A metal plate is located above the top opening and supported by two rubber plates. A hitting device is connected to the rear box and includes a case which includes lugs. A rod has a sphere on a first end thereof and a pivotal end on a second end of the rod, the pivotal end is pivotably connected to the lugs. An operation unit is connected to the case and pushes the pivotal end of the rod so that the sphere is lowered to hit the metal plate.

Referring to FIGS. 1, 2 and 2A, the chime bar assembly of the present invention comprises a hollow body 10 including a resonation space 14 defined therein, the hollow body 10 including a front opening 12, a rear opening 13 and a top opening 11. A front cover 20 has an engaging portion “A” which is engaged with the front opening 12 of the hollow body and the front cover 20 seals the front opening 12 of the hollow body 10. The front cover 20 further includes a leg portion “B” for standing on a table top. A rear box 40 has another engaging portion “A” which is engaged with the rear opening 13 of the hollow body 10 and the rear box 40 seals the rear opening 13 of the hollow body 10. The rear box 40 further includes another leg portion “B” for standing on a table top. A handle 41 is connected to the rear box 40.
A metal plate 30 is located above the top opening 11 and two rubber plates 31 are connected between the hollow body 10 and the metal plate 30. Each of the two rubber plates 31 has bosses 32 on which the metal plate 30 are supported. Two screws 60 extend through two washers 70, two holes in the metal plate 30, two holes in the two rubber plates 31 and are connected to the hollow body 10.
A hitting device 50 is connected to the rear box 40 and includes a case 51 which includes two lugs 511 on a front end thereof. A rod 80 has a sphere 81 on a first end thereof and a pivotal end 82 on a second end of the rod 80, the pivotal end 82 is pivotably connected to the lugs 511.
An operation unit 53 is connected to the case 51 and includes a first passage 512 defined axially through front and rear ends thereof and a second passage 513 is defined through a top of the case 51. The second passage 513 is perpendicular to the first passage 512. A push rod 52 is located in the first passage 512 and a first end of the push rod 52 extends out from the front end of the case 51, the first end of the push rod 52 is in contact with the pivotal end 82 of the rod 80. A first inclined surface is defined in a second end of the push rod 52. An operation rod 532 includes a second inclined surface defined in a lower end thereof, the first and second inclined surfaces are slidably engaged with each other. A top end of the operation rod 532 extends from the top of the case 51 and extends through a top cover 533. A spring 531 is received in the top cover 533 and mounted on the operation rod 532. A button 534 is connected to the top end of the operation rod 532.
As shown in FIGS. 3 and 3A, when pushing the button 534, the operation rod 532 is lowered to push the push rod 52 which pivots the pivotal end 82 so that the sphere 81 of the rod 80 is lowered to hit the metal plate 30.
FIGS. 4 and 5 show the second embodiment of the chime bar assembly of the present invention, wherein the two rubber plates 31 each have a protrusion 34 on its bottom so as to be engaged with holes in the hollow body 10. Each rubber plate 31 further includes a connection part “C” so that the metal plate 30 is securely engaged with the connection parts “C”. The rear box 40 is cooperated with a rear cover 90 which has the engaging portion “A” and the leg portion “B”. The rear box 40 is connected to the rear cover 90 and the hollow body 10 by four pins 91 as shown.
FIGS. 6 to 9 show the third embodiment of the chime bar assembly of the present invention, wherein the hollow body 10, the front cover 20 and the rear box 40 have a polygonal outside. The two lugs 511′ extend from a top of the rear box 40 and the case 100 is pivotably, connected to the lugs 511′ by a pin 120. The hitting device 50′ has a flexible member 110 received in the case 100 thereof and the rod 80′ has an end inserted into the case 100 and is connected with the flexible member 110. The user holds the handle 41 and shakes up and down to let the rod 80′ pivoted about the pin 120 such that the sphere 81′ of the rod 80′ can hit the metal plate 30.
FIGS. 10, 11, 12 and 12A show a fourth embodiment of the chime bar assembly wherein the push rod 52 is longer than that in the first embodiment and does not have the first inclined surface, the second end of the push rod 52 extends out from the rear end of the case 51. An operation plate 130 is pivotably connected to the lugs 511 on a top of the case 51 and includes an operation surface 131 which can be pushed to push the second end of the push rod 52 so as to pivot the pivotal end 82 of the rod 80 as shown in FIGS. 13, 13A.
FIGS. 14 to 16 show a fourth embodiment of the chime bar assembly wherein the hollow body 10 is a tubular body with a circular cross sectional section, and each of the front cover 20 and the rear cover 90 includes a tubular portion “D” which is inserted into the hollow body 10.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
