Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a portable liquid container such as a portable metal thermos bottle and a thermos bottle containing a portable vacuum double glass bottle.

(Prior Art) Conventionally, as a portable liquid container provided with this kind of handle, the one described in Japanese Utility Model Laid-Open No. 58-95730 is known. This is one in which both ends of the handle are rotatably pivotally attached to both of the ring parts attached to the shoulder and the bottom of the container outer casing, and an expandable part is provided in a part of the handle. By extending the extendable part so that the grip part of the handle protrudes further outward than the protruding height of both rings, and retracting the expandable part when the handle is stored, the handle has a height approximately equal to the protruding height of both ring parts. It is configured to fit inside.

(Problems to be Solved by the Invention) In the above-mentioned conventional device, there is no urging device for moving the grip portion of the handle to the used state or the stored state, and there is also a locking device for maintaining each state. The problem is that the handle is neither stable nor stationary in each state because it is absent or extremely simple, and it is insufficient to prevent trouble in handling due to an inadvertent change in the state of the handle. have.

On the other hand, Japanese Utility Model Publication No. 37-22861 discloses that by connecting both ends of a handle to a ring that is provided on a container so that the ring can be undulated, the handle is pulled away from the outer surface of the container with the undulation of each ring. It can be made easier or can be stored along the outer surface of the container, and a tension spring is operated between the free ends of each ring to urge each ring inward to pull the handle. It discloses that it can be held in the storage position.

However, in such a structure, in order to stabilize the handle in the retracted state, only the ends of the rings are attracted by the springs, so the force that regulates the mutual postures of the ring and the handle is insufficient. In addition to the ease of swinging due to the support of both ends by the undulating ring, the posture holding function of the handle is weak and it is difficult to use.

Further, Japanese Utility Model Laid-Open No. 62-157431 discloses that both ends of a handle are pivotally connected to a container, but a free end of a swinging support whose one end is pivotally connected to the container is slidable in the longitudinal direction of the handle. It is connected via a shaft, and a spring is attached to the pivot of the rocking support so that the rocking support is actuated between the rocking support and the body in the upright direction. It discloses that it is firmly stabilized in a separated use position.

However, with such a structure that works the spring with the container, when the handle is in the use position, the side of the spring that acts on the body is exposed, and there is a risk that the hand holding the handle will get caught and hurt. It's hard to do, and it's also unclean. There is also a problem that dust easily collects in the spring portion and a small gap between the spring portion and the adjacent member, and the dust cannot be easily cleaned.

The present invention is capable of reliably changing the handle from the stored state to the used state or from the used state to the stored state by an extremely simple operation, and maintains each state in a stable manner. It is an object of the present invention to provide a portable liquid container having a handle which is sufficient for preventing a trouble in handling due to a change and which is hard to get dirty and safe for use.

(Means for Solving the Problem) In order to achieve the above object, the present invention provides a swing support body in which at least one end of a handle is pivotally connected to a container in order to pivotally connect both ends of the handle to the container. A swinging shaft that is movable in the longitudinal direction of the handle is connected to the swing end, and a spring is installed between the handle and the sliding shaft to pull the sliding shaft toward the center of the handle. The moving support is urged toward the side where the handles are retracted along with the removal of the refraction, and the handle and the swing support are bent to the maximum with the movement of the sliding shaft toward the handle end. The first feature of the present invention is that a pair of members are provided so as to be brought into close contact with each other when the handle is separated from the container in a use state and to relatively move an attitude stabilizing contact surface that stabilizes the use state.

Also, in order to pivotally connect both ends of the handle to the container, at least one end of the handle is movably supported pivotally connected to the container via a sliding shaft held by a slide rod provided so as to advance and retreat to this end. A spring, which is connected to the swinging end of the body and moves the slide rod between the slide rod and the handle, is provided inside the hollow portion of the handle so that the handle and the swing support can be bent as much as possible to make the handle Energize to the side where the container is in use and away from the container, and lock the slide rod in the retracted position to hold the handle and the swing support body in a retracted state where the handle and the swing support are not bent. The second feature is that the means and the operating portion for operating the locking means are provided.

It is preferable that the locking means should be elastically engaged with the slide rod to lock the handle in the retracted state when the handle is retracted.

Furthermore, in order to pivotally connect both ends of the handle to the container, at least one end of the handle is connected to the swing end of the swing support pivotally connected to the container, to the handle end or the swing end of the swing support. They are connected via a sliding shaft movably provided in their longitudinal direction, and a spring for urging the handle and the swing support member to urge them toward the use state where they are bent as much as possible so that the handle is separated from the container. Means for providing a function in the hollow portion and engaging with and locking the other of one of the pair of members that moves relative to each other when they are refracted and the handle is stored along the container The third feature is that it is provided with an operating section for operating the locking means.

Here the spring is actuated to push them apart between the connecting ends of the rocking support and the handle.

The locking means is also acted between the handle and the container. Alternatively, the locking means are actuated between the handle and the rocking support.

Further, the locking means may be adapted to retain the state by elastic engagement when the handle is in the retracted state.

(Operation) The present invention is configured as described above, and in the first feature thereof, the handle is a container having no bending between the handle and the swing support by a spring that acts between the handle and the sliding shaft. Since it is urged toward the side of the stored state along with, it is possible to normally stabilize in this stored state. When the handle is pulled outward against the urging force of the spring, the handle can be switched to a usable state in which it can be gripped away from the container while being bent by the sliding support body while being bent by the swing support. In this use state, the posture stable contact surfaces provided between the pair of members that move relative to each other come into contact with each other to stabilize the handle state against the biasing means, so that it is not possible to inadvertently restore the stored state. Can be prevented. When the handle is pressed toward the retracted state against the contact force of the posture stabilizing contact surface in the use state, the stability to the use state is lost, and therefore the handle is automatically returned to the retracted state by the biasing means.

In particular, since the spring is made to work in the hollow part of the handle by making use of the fact that it works between the handle and the sliding shaft, it is not exposed during use, and the danger of catching fingers or dust is accumulated and it is impure. The problem of becoming

In the second feature, the handle is urged toward the in-use side by a spring that is provided at the end of the handle so that the slide rod can be advanced between the handle and the slide rod that holds the slide shaft. However, the retracted slide rod is engaged with the retaining means so that the retracted state can be retained and stabilized, and in particular, by utilizing such a way of operating the spring, the spring is provided in the hollow portion of the handle. Therefore, there is an advantage that safety in use and prevention of dirt can be achieved as in the case of the first feature. When the locking means is operated to release the locking by the operating portion in this stored state, the handle is automatically switched to the use state by the urging by the urging means, and is brought into the use state by the sliding limit of the sliding shaft at that time. Can be stable.
The handle in the used state can be pushed back to the stored state by resisting the urging by the urging means, and the state can be locked and stabilized by the locking means.

Moreover, the biasing force by the spring is little or weak when the handle is in the retracted state in which the handle is aligned with the swing support, and does not cause a sudden change in state even when the lock to the retracted state is released. The handle is slightly moved to the use side, or slowly moved to the use state, so that the user does not feel an unexpected feeling.

If the locking means is adapted to elastically engage the handle or the swing support when the handle is in the retracted state, the handle returned to the retracted state can be automatically locked.

Further, in the third feature, the operation is the same as that of the second feature except that the connection structure of the handle and the swing support and the structure of the locking means are different.

Also, the handle is urged by a spring toward the side to be used, but when it is operated to push them apart between the handle and the swing support, the swing support and the handle are stored in line. In the state, it hardly works or is weak even if it works, it does not cause a sudden state change even if the lock to the retracted state is released, the handle is slightly moved to the used side or slowly moved to the used state. As a result, it does not give the user an unexpected feeling.

The locking means has the same function regardless of whether it is operated between the handle and the container or between the handle and the swing support.

Further, when the locking means is changed to the retracted state of the handle so as to maintain the state by elastic engagement, the locked state of the handle can be automatically performed.

(Embodiment) The present invention will be described below based on an embodiment shown in the drawings.

1 and 2 show a first embodiment of the present invention.

In this first embodiment, a vacuum double container 1 made of stainless steel, a synthetic resin shoulder member 2 attached to a bottle mouth portion 5 of the vacuum double container 1, and a synthetic resin bottom member 3 attached to a bottom portion 6 of the container 1. Also, the present invention relates to a portable metal container thermos bottle in which a handle 8 is attached to a container body 7 composed of a stopper body 4 for closing the bottle mouth portion 5.

A cup 9 also serving as an outer lid is detachably screwed to the shoulder member 2. Further, the outer body portion 10 of the vacuum double container 1 is formed in a cylindrical shape except for both end portions.

Both ends of the handle 8 are mounting portions 11a, 1a provided on the outer body portion 10
It is connected to 1b through a swing support 16. One mounting part 11
The a is integrally formed on one side of the shoulder member 2, and the other mounting portion 11b is integrally formed on a part of the synthetic resin ring 26 fitted to the outer body portion 10. A support wall 13a is formed on the upper portion of one of the mounting portions 11a, and L is attached at an appropriate position on the support wall 13a.
A die hanging hole 14a is formed. Other mounting part 1
A support wall 13b is formed on the upper portion of 1b, and a hooking hole 14a for the L-shaped hanging string 12 is formed at an appropriate position on the support wall 13b.

Each swing support body 16 is swingably supported on the support walls 13a, 13b via a pivot shaft 17 at a base end portion thereof,
The tip end is connected to the handle 8 via the sliding shaft 18. The sliding shaft 18 is provided at the swinging end of the swinging support 16 so as to penetrate right and left, and is slidably fitted in the long hole 20 of the handle 8. Further, as shown in the figure, the handle 8 is hollow by fitting a front plate having a groove on the back side and a back plate applied to the back side of the front plate so as to close the opening of the groove, and the sliding shaft 18 The sliding end of the rocking support 16 can be received as shown in the right half of FIG. 2, or can be pulled out as shown in the left half of FIG.
Here, since the swing support 16 only swings at a fixed position, the slide shaft 18 is moved even when the handle 8 is brought into contact with and separated from the container body 7.
With the sliding of the handle 8, the handle 8 responds to the swing of itself, enabling the handle 8 to be switched between the stored state (the right half of FIG. 3) and the use state (the left half of the FIG. 2). Between the sliding shaft 18 and the support pin 21 inside the handle 8, a tension spring 22 is provided in the hollow portion of the handle 8 and is operated. The spring 22 urges the swing end of the swing support 16 in one direction to pull it into the handle 8, that is, the handle 8 is always stored. Next, the operation of the mechanism of the first embodiment will be described.

Now, when changing the state of the handle 8 from the stored state to the used state, the grip body 12 is separated from the outer periphery of the container 1 and the pivot shaft 18
It may be lifted until it stops at the tip of the long hole 20. The handle 8 has a frictional force on the shafts 17 and 18, a contact frictional force between the supporting walls 13a and 13b and the rocking support 16, and the like. It resists urging and can be stabilized in use.

When changing the state of the handle 8 from the use state to the storage state, if a part of the handle 8 is lightly pushed in the direction in which the handle 8 approaches the outer periphery of the container body 7, the stable action force in the use state is balanced. When the handle 8 collapses, the restoring force of the spring 22 reliably and automatically puts it in the retracted state and stabilizes it.

In particular, since the spring 22 is provided between the handle 8 and the sliding shaft 18 so as to be provided inside the hollow portion of the handle 8 and is used, the spring 22 is not exposed during use, and there is a danger of catching fingers. It also solves the problem of dust and dirt becoming dirty.

The connecting portion between the handle 8 and the swing support 16 is a pivot shaft 18, an elongated hole.
In order to protect the mechanism composed of 20 and the vine winding spring 22 from being exposed and to improve the appearance as a product, it is preferable to cover it with a bellows type cover 25 made of soft rubber or synthetic resin. It is desirable that the both ends of the cover 25 be fixed to the outer peripheral end surface 23 of the grip body 12 and the outer peripheral end surface 24 of the swing support body 16.

3 and 4 show a second embodiment of the present invention.

In the second embodiment, the handle 8 is connected to the one mounting portion 11a via the swing support 16 in a state close to that of the first embodiment. On the other mounting portion 11b, a pivot shaft 17b is attached to the protrusion 11c for obtaining the same appearance as the connecting portion to the mounting portion 11a.
Are directly linked by. A sliding shaft 18 connecting the handle 8 and the swing support 16 is slidable by being provided at the tip of a slide rod 27 held by the handle 8 so as to be able to move back and forth. In addition, the pivot shaft 17b can be slightly slid by the elongated hole 20 of the handle 8 at the connecting portion between the handle 8 and the protrusion 11c. As a result, the handle 8 is moved into and out of contact with the container body only by the mounting tool 11a, with the swing support 16 swinging and the slide shaft 18 sliding.

A central portion of the slide rod 27 is slidably fitted and held in a hole 33a formed in a partition wall 33 in the handle 8. A stopper (30) is operated on a portion of the slide rod (27) protruding inward from the partition wall (33). The stopper 30 is urged by a spring 29 to engage with a locking portion 26 provided inside the slide rod 27, so that the slide rod 27 is maximally pulled into the handle 8, that is, the handle 8 is in a retracted state. Locked in position. The stopper 30 has a push button protruding to the back of the handle 8.
21 is provided such that the button 21 is pushed against the spring 29 to release the lock. A compression spring 22 is actuated between the partition wall 33 and one end side spring seat 31 of the slide rod 27 to urge the sliding shaft 18 and the slide rod 27 to the left in the figure.

Next, the operation of the mechanism of the second embodiment will be described.

Now, it is assumed that the handle 8 is in the storage state as shown in FIG. At this time, the slide rod 27 and the sliding shaft 18 are urged to the left in the drawing by the spring 22, but the slide rod 27 is not responding to this because the slide rod 27 is locked. Therefore, the stored state of the handle 8 is reliably maintained.

When changing the state of the handle 8 from the storage state shown in FIG. 2 to the use state shown in FIG. 4, the push button 21 is pressed. Then, the stopper 30 is pushed against the spring 29, disengages from the locking portion 26 of the slide rod 27, and unlocks the slide rod 27. At this time, the slide guide 27 tries to move to the left in FIG. 3 together with the slide shaft 18, and pushes the swing end while raising the swing support 16. For this reason, the handle 8 is automatically pushed away from the container body 7 by the rising of the swing support 16, and the state of use shown in FIG. 4 is obtained. This condition is then stabilized by the fact that the sliding shaft 18 is pushed by the spring 22 until the sliding limit is reached.

In the second embodiment, as shown in FIGS. 3 and 4, the position of the pivot shaft 17 at the base end of the rocking support 16 is set slightly from the direction Xa in which the compressive force of the arm spring 22 acts. If the handle 8 is moved in the direction Xc deviated by the angle α to the point 17c, the change from the stored state of the handle 8 to the used state becomes more reliable.

To change the state of the handle 8 from the used state to the stored state, the handle 8 may be pushed so as to approach the outer body portion 10 of the container 1. At this time, the sliding shaft 18 and the slide rod 27 are moved to the right against the handle 8 against the spring 22, and the locking portion 26 is moved to the stopper 30.
To be locked. As a result, the handle 8 is brought into the storage state shown in FIG. 3 and is stabilized.

Also in the case of the present embodiment, since the spring 22 is made to be contained in the handle 8 by utilizing the above-described way of operating the spring 22, the first
As in the case of the above feature, there is an advantage that safety in use and prevention of dirt can be achieved.

5 and 6 show a third embodiment of the present invention.

The third embodiment shows a simpler alternative to the combined structure of the slide rod and the stopper in the second embodiment.

Both the handle 8 and the swing support 16 have longitudinal holes 56 and 57 having a common center line in the retracted state shown in FIG. 5, and the stopper rods are located in the elongated holes 56 and 57. 51 penetrates across both sides. The tip of the stopper rod 51 is bent into an L-shape to form an operating portion 54, which is a long hole provided on the surface of the handle 8.
It projects through the surface through 55. The stopper rod 51 can slide in the handle 8 in the axial direction within the length of the elongated hole 55 by the operating portion 54. The stopper rod 51 is provided with a locking projection 52 so as to elastically mesh with a locking recess 53 in the handle 8. A compression spring 22 is actuated between the end faces of the handle 8 and the swing support 16 which face each other, and in the retracted state of the handle 8 in FIG. I am biased.

Next, the operation of the mechanism of the fourth embodiment will be described.

Now, it is assumed that the handle 8 is in the storage state as shown in FIG. At this time, the stopper rod 51 is connected to the hole 56 of the handle 8 and the rocking support member 16.
When the stopper projection 51 of the stopper rod 51 is positioned so as to be engaged with the engaging recess 53 of the handle 8, the stopper rod 51 moves in the axial direction thereof. Since it does not move, the handle 8 and the swing support 16 are in a substantially straight line state, and the retracted state in which the handle 8 is in close contact with the outer body portion of the container 1 is reliably maintained.

When changing the state of the handle 8 from the retracted state shown in FIG. 5 to the used state shown in FIG. 8, the operating portion 54 slides to the right to lock the stopper rod 51 against the engagement with the engaging recess 53. The projection 52 and the tip of the stopper rod 51 and the hole 56 of the rocking support 16 through which this penetrates are disengaged. Then the rocking support
The reference numeral 16 is automatically separated from the outer body portion 10 of the container 1 by the restoring force of the spring 22 with the sliding shaft 18 sliding, and the handle 8 is also separated from the outer body portion 10 of the container 1, as shown in FIG. It will be in such a usage state.

In order to change the handle 8 from the use state to the storage state, the handle 8 is pushed so as to approach the outer tube portion 10 of the container 1 and the operating portion is pressed.
The stopper rod 51 is moved to the left by 54 so that its tip is fitted into the hole 56 of the swing support 16 and the locking projection 52 is locked by the locking recess 53.
Stabilize by engaging with. As a result, the handle 8 and the swing support 16 are locked at the relational position shown in FIG. 5, and the handle 8 is stored.

(Effects of the Invention) Since the present invention is configured as described above, it has the following effects.

What is common to each claim is that the handle of the portable liquid container can be surely brought into a used state and a stored state by a simpler and easier operation as compared with the prior art, and those states are provided with a spring. By the cooperation of the force, the stabilizing means and the locking means, it is stable against external force and is easy to use, and it is possible to prevent trouble in handling due to an inadvertent change in state. Further, the structure provided in the hollow portion of the handle utilizing how the spring works prevents the spring from being exposed during use, and eliminates the danger of catching a finger or the problem of dust collecting and becoming unclean. .

In addition to the common effects described above, each claim has the following effects.
