Abstract

A toy assembly is provided with manual and electrical operation units which can be selectively actuated to rotate a shaft, which has a helical advancing path, in one direction in an ascending chamber. Toy elements are moved upward in the ascending chamber and descend by gravity along a descending path provided in a descending chamber. The manual operation unit incorporates a first clutch mechanism for disconnecting the manual operation unit from the rotary shaft so as to prevent the rotary shaft to turn in another direction that can move the toy elements downward. A second clutch mechanism is provided to disconnect the rotary shaft from the electrical operation unit when the rotary shaft is driven via the manual operation unit.

Claims

1. A toy assembly comprising:

a support having an ascending chamber, at least one descending chamber, an upper passage intercommunicating the tops of said ascending and descending chambers, a lower passage intercommunicating the bottoms of said ascending and descending chambers;

at least one movable toy element which is movable in said ascending chamber, said upper passage, said descending chamber, and said lower passage;

a rotary shaft rotatably mounted in said ascending chamber and having a helical ridge formed on the periphery thereof to provide an ascending path for said movable toy element, said rotary shaft being rotatable in one direction to move said movable toy element from said lower passage to said upper passage;

a descending path provided in said descending chamber for said movable toy element to descend by gravity from said upper passage to said lower passage;

a manual operation unit connected to the top of said rotary shaft for driving said rotary shaft, said unit including a first clutch mechanism for disconnecting said rotary shaft from said manual operation unit when said manual operation unit is turned in a direction opposite to said one direction of said rotary shaft;

an electrical operation unit mounted on said support and connected to the bottom of said rotary shaft for driving said rotary shaft in said one direction; and

a second clutch mechanism provided between said electrical operation unit and said rotary shaft for disengaging said rotary shaft from said electrical operation unit when said manual operation mechanism is operated.

2. A toy assembly as claimed in claim 1, wherein said manual operation unit includes a manually operable rotary member provided at the top of said support to be connected to the top of said rotary shaft, and a first driven shaft connected to said rotary member, said first clutch mechanism including a fixed clutch plate coaxially coupled to said first driven shaft, a movable clutch plate which is connected to said rotary shaft and which is mounted movably on said first driven shaft for being engaged with or disengaged from said fixed clutch plate, and a cam mechanism provided between said fixed and movable clutch plates for camming said movable clutch plate to disengage from said fixed clutch plate when said rotary shaft is turned in a direction opposite to said one direction.

3. A toy assembly as claimed in claim 2, wherein said first cam includes a cam projection formed on said fixed clutch plate, a concavity formed on said movable clutch plate to receive said cam projection, said concavity having an abutment face to be pushed by said cam projection when said manually operable rotary member rotates in said one direction of said rotary shaft, and an inclined face to be cammed by said cam projection when said manually operable rotary member rotates in a direction opposite to said one direction of said rotary shaft.

4. A toy assembly as claimed in claim 1, wherein said rotary shaft is hollow and has a covering seat plate at the bottom of said rotary shaft for simultaneous rotation, and a cylindrical insert integral with said covering seat plate and extending into said rotary shaft.

5. A toy assembly as claimed in claim 4, wherein said electrical operation unit has a second driven shaft to be operated electrically and extending into said cylindrical insert, said second clutch mechanism comprising a fixed clutch member which is fixed to said second driven shaft and which has clutch teeth annularly disposed around said second driven shaft, a movable clutch member movably mounted to said second driven shaft and engaged with said cylindrical insert for simultaneous rotation, said movable clutch member having a plurality of annularly arranged recesses to releaseably engage said clutch teeth, said recesses being capable of disengaging from said teeth when said second driven shaft is inoperative.

6. A toy assembly as claimed in claim 1, wherein said support has a tree-like shape and includes two descending chambers on two sides of said ascending chamber, said support further having a receiving chamber below said ascending chamber to receive said electrical operation unit.

7. A toy assembly as claimed in claim 1, wherein said descending chamber has a plurality of inclined plates which are arranged one below the other to provide said descending path.
