Abstract

A combined structure of a hand-held cordless vacuum cleaner and a flashlight comprises;

a vacuum cleaner body housing therein a battery and an electric powered blower, and including switch means adapted to control power fed to said blower;

a dust case;

a flashlight case including a lighting unit;

specific interconnecting means adapted to releasably interconnect either one of said dust case and said flashlight case to said vacuum cleaner body; and

specific electrical connection means adapted to electrically connect said battery in said vacuum cleaner body to said lighting unit in said flashlight case when said flashlight case is interconnected to said vacuum cleaner body by said interconnecting means.

Claims

1. A combined structure of a hand-held cordless vacuum cleaner and a flashlight comprising;

a vacuum cleaner body having a handle portion, housing therein a battery and an electric powered blower driven by said battery, and including switch means adapted to control power fed to said blower;

a dust case housing therein a filter;

a flashlight case including a lighting unit and switch means for said lighting unit;

interconnecting means adapted to releasably interconnect either one of said dust case and said flashlight case to said vacuum cleaner body; and

electrical connection means adapted to electrically connect said battery in said vacuum cleaner body to said lighting unit in said flashlight case when said flashlight case is interconnected to said vacuum cleaner body by said interconnecting means,

said interconnecting means being composed of;

an annular stepped portion formed in the front peripheral edge portion of said vacuum cleaner body;

a clamping portion and an engaging portion respectively formed in the upper and lower part of said annular stepped portion;

an annular recess formed in the rear peripheral edge portion of each of said dust case and said flashlight case and releasably fitted to the annular stepped portion of said vacuum cleaner body in a substantially fore-and-rear direction; and

upper and lower locking portions formed in the vicinity of said annular recess to be respectively locked to the clamping portion and the engaging portion of said annular stepped portion,

and said electrical connection means being composed of;

a recess formed in the annular stepped portion of said vacuum cleaner body;

battery side connection terminals disposed in said recess and led to said battery; and

light bulb side connection terminals projected to the annular recess of said flashlight case, led to said lighting unit and coming into the recess in the annular stepped portion of said vacuum cleaner body to be brought into contact with said battery side connection terminals when said flashlight case is interconnected to said vacuum cleaner body.

2. A combined structure according to claim 1, wherein said interconnecting means further includes locking means adapted to automatically lock said switch means on said vacuum cleaner body into the OFF state when said flashlight case is interconnected to said vacuum cleaner body.

3. A combined structure according to claim 2, wherein said locking means comprises;

a projection provided in the annular recess in said flashlight case; and

a slide lever arranged in said vacuum cleaner body to be slid by said projection when said flashlight case is interconnected to said vacuum cleaner body, thereby to lock said switch means on said vacuum cleaner body into the OFF state.

4. A combined structure according to claim 2, wherein said upper locking portion is formed in the upper outer wall surface of each annular recess of said dust case and said flashlight case, said clamping portion is formed of a seesaw-like molded member pivoted to the upper part of the annular stepped portion of said vacuum cleaner body, and the front end part of said molded member is locked to said upper locking portion when each of said cases is interconnected to said vacuum cleaner body;

and wherein said locking means is a locking piece formed at the rear end part of said seesaw-like molded member for locking said switch means on said vacuum cleaner body into the OFF state when said flashlight case is interconnected to said vacuum cleaner body.

5. A combined structure according to claim 1, wherein said flashlight case is composed of;

a tubular body;

a lighting unit accommodated at the front part within said tubular body;

switch means for said lighting unit; and

a rear plate accommodated at the rear part within said tubular body to cooperate with said tubular body thereby to form said annular recess.

6. A combined structure according to claim 5, wherein said rear plate includes bulb side connection terminals led to said lighting unit, and said switch means.

7. A combined structure according to claim 6, wherein said switch means is composed of;

a leaf spring formed integrally with said rear plate;

a power feeding terminal extended from one of said bulb side connection terminals; and

a control lever having an upper portion projected to the outside from a through hole formed in said tubular body and actuated upon operation of said projected portion thus causing said power feeding terminal to come into contact or non-contact with said lighting unit via said leaf spring.

8. A combined structure according to claim 6, wherein said rear plate has an upper guiding projection adapted to guide said control lever and a lower projection adapted to support said bulb side connection terminals, and these projections are respectively fixedly fitted into corresponding opening formed in said tubular body.

9. A combined structure according to claim 1, wherein said lighting unit comprises a reflection mirror provided a miniature bulb and a lens for covering the front of said reflection mirror.

10. A combined structure according to claim 1, wherein said battery is of a chargeable battery.
