Description

[Detailed description of the invention] The present invention provides an air pot in which the stored liquid is poured out to the outside by supplying pressurized air into the medium bottle via a built-in air pump. This invention relates to improvements in pump operating devices.

This type of operating device generally includes a swinging lever for directly pressing the air pump, an operating lever pivotably mounted above the swinging lever, and both levers can be linked when the operating lever is raised, and when the linkage is released. It consists of an interlocking/releasing mechanism that can lower the operating lever.

The previously known linking/releasing mechanism includes (a) linking the operating lever to its pivot pin through an elongated hole, and pushing and pulling the operating lever between the operating lever and the swinging lever. and an engaging part and an engaged part that engage with each other when the elongated hole is positioned toward one side of the pin and release the engagement when the long hole is positioned toward the other side. (b) An engaging element that rotates in a vertical position by its own weight when standing up is pivotally attached to the operation lever, while a recessed groove is formed in the swinging lever to engage the engaging element in the vertical position. However, in the former (a), it is troublesome to push and pull the operating lever, and in the latter (b), the engagement force is weak, resulting in unexpected release, which is extremely dangerous.

The present invention is primarily aimed at solving this problem, and embodiments of the light chamber will be described below with reference to the drawings.

Reference numeral 1 denotes a lid body which is integrally connected with a handle part 2, and has an air pump 3 built therein.

A base portion of a swing lever 5 for pressing the pump 3 is pivotally attached to a bottom plate 4 to which the pump 3 is integrally connected.

6 is a check valve attached to the upper part of the pump 3, and a spring 7
It is biased open by.

This check valve 6 is closed by the swing lever 5 when the pump 3 is pressed.

Reference numeral 8 denotes an operating lever, the base of which is pivotally attached to the base of the hand portion 2.

The operating lever 8 assumes a posture in which it is housed within the handle portion 2 when it is swung down and swung, and a posture that protrudes above the holder portion 2 when it is swung up and down.

A downward engaging protrusion 9 is integrally provided near the pivot base of the operating lever 8, and an engaged piece 10 is pivotally attached to the swing lever 5 at a position corresponding to the engaging protrusion 9. There is.

This secured piece 10 is integrally connected with an operation part 11 which is U-shaped when viewed from above and is exposed in the finger insertion space S between the lid body 1 and the handle part 2.

A helical spring 13 is provided around the pivot axis of the swingable regulating member 12, which is integral with the engaged piece 10 and the operating portion 11, relative to the swinging lever 5.

This spring 13 allows the regulating member 12 to
a is biased in the direction of contacting the protrusion 5a on the upper surface of the swing lever 5.

11b is a space passing through the upper and lower sides of the operating section 11, and the engaging protrusion 9
Insert position.

14 is a medium bottle for storing liquid, and a pump 3 is attached to the stopper 15.
A communication hole 15a is formed therein, and a liquid spouting pipe 16 is connected thereto.

Note that 17 is a check valve.

Next, the operation will be explained with reference to FIG. 3. When the operating lever 8 is raised, the engaging protrusion 9 presses the engaged piece 10, causing the regulating member 12 to swing against the spring 13.

When the engaging protrusion 9 is completely removed from the through space 11b and separated from the secured piece 10, the regulating member 12 is returned to its original position by the spring 13 (the position where the operating lower surface 11a abuts the protrusion 5a). (Figure 3 A).

When the operating lever 8 is pushed down in this state, the engaging protrusion 9 becomes engaged and interlocked with the engaged piece 10, and when the operating lever 8 is further pushed down to the holding position of the opposing hand part 2, the pushing down force is reduced. is transmitted to the swinging lever 5 via the regulating member 12, and this lever 5 closes the valve 6, compresses the pump 3, and forces air into the medium bottle 14, so that the liquid in the medium bottle 14 is will be forced to the outside via the spout pipe 16 (in Fig. 3).

When the push-down force on the operating lever 8 is released, the return force of the pump 3 and the spring 7 returns the operating lever 8 to the upright protruding position via the swing lever 5 and the regulating member 12.

In this state, the engaging projection piece 9 and the engaged piece 10 are in an interlocking state.

Therefore, the control member 12 is pressed against the spring 13 by pressing the operating part 11.
When the lever 8 is swung against this, the interlocking engagement between the engaging projection piece 9 and the engaged piece 10 is released, and the operating lever 8 is brought into the collapsed position stored in the handle part 2 by its own weight, and is not engaged. The mating piece 9 is the operating part 11
(See Fig. 3).

In summary, the air pot operating device configured as described above is as follows:
A swinging lever 5 for pressing the air pump 3 and an operating lever 8 which is pivotally connected to the pot holding part 2 and can be switched between a lying down storage position and an upright protruding position by swinging can be linked and unlinked. In this structure, a downward engaging protrusion 9 is provided near the pivot base of the operating lever 8, and
An engaged piece 10 that can be switched between a state in which it engages with the engagement protrusion 9 and a state in which it is released from engagement is attached to a portion of the swing lever 5 corresponding to the engagement protrusion 9 via a spring 13. The engaged piece 10 is provided with a force biased toward the engagement interlocking state, and the engaged piece 10 includes an operating section for switching the engaged piece 10 to the engagement release state against the urging force of the spring 13. 11 are arranged in series, so that the operating lever 8 and the swinging lever 5 are interlocked by switching the operating lever 8 to the upright protruding position, and
It is characterized in that it is configured so that the operation lever 8 and the swinging lever 5 are released from interlocking by a pressing operation against the biasing force of the operation section 11, and the engagement protrusion 9 and the engaged Piece 10
The engagement and interlocking is performed dynamically by simply swinging the operating lever 8 into the upright and protruding position, and the engaged and interlocking state is strongly maintained by the biasing force of the spring 13. This locking and interlocking state can be easily released by pressing the operating part 11, and after this release, the operating lever 8 will be folded and stored in the handle part 2 due to its own weight. Although the property can be made much simpler than the conventional one mentioned above, the interlocking state is maintained much more strongly than the conventional one mentioned above. A high level of safety has been ensured without any accidental release.
