Description

[Detailed description of the invention] (a) Industrial application field This invention relates to a handle folding mechanism for a portable thermal water bottle used outdoors, for example.

(B) Prior Art Conventionally, as a handle folding mechanism for the heat-retaining water bottle of the above-mentioned example, there are structures described in, for example, Japanese Utility Model Application Publication No. 61-35645 and Japanese Utility Model Application Publication No. 58-95730.

In other words, the former disclosed in Japanese Utility Model Application Publication No. 61-35645 has pivot parts formed at two places on the upper side and two places on the lower side of the grip that extends in the vertical direction, and left and right supports are provided for each of these pivot parts. In addition to connecting the pieces, the pins protruding from the left and right support pieces are slidably fitted loosely into the long holes of the body ring.

However, in this conventional structure, in order to configure the handle, there are a total of 5 grips and 2 upper and lower support pieces.
This method not only requires a large number of parts and increases the number of assembly steps, but also allows the handle to be retracted even when the above-mentioned gripping section is gripped when the handle is pulled out. There was a problem that the thermal water bottle was unstable when filling with water.

On the other hand, the latter disclosed in Japanese Utility Model Application Publication No. 58-95730 has body rings fixed to the upper and lower outer peripheries of the outer container of the heat-insulating water bottle, and a pair of U-shaped rectangular cylinders are attached to these upper and lower body rings. In this structure, the handle base piece is pivotally mounted to be openable and closable, and a handle is provided inside the opening of each handle base piece so as to be extendable and retractable.

However, this conventional structure requires a total of four parts, two handle base pieces and two gripping parts, to construct the handle, which not only increases the number of parts and the number of assembly steps, but also increases the number of parts required for assembly. Even when the pair of gripping parts are gripped when the bottle is pulled out, the gripping parts are allowed to move in the storage direction, so there is a problem in that the thermal water bottle is unstable when pouring water.

(c) Purpose of the invention This invention aims to significantly reduce the number of parts that make up the foldable handle, reduce assembly man-hours, and improve the stability of the heated water bottle when pouring water. The purpose is to provide a tatami mechanism.

(d) Structure of the invention This invention consists of body rings fixed to the top and bottom of the outer periphery of the outer container of a thermal water bottle, long grooves formed on the left and right sides of the facing surfaces of each of the body rings, and the top and bottom of the grip section extending in the vertical direction. It is equipped with two U-shaped handles integrally formed with support pieces extending in the horizontal direction.
A pivot part formed approximately half the thickness of the support piece is provided approximately in the middle of each support piece of the book handle, and each support piece of the two handles is pivoted to the pivot part. At the same time, a pin integrally formed vertically from the base end of the support piece of the handle is slidably fitted into the long groove, and when the handle is stored, the pin is inserted into the long groove. The mechanism is characterized in that the length of the elongated groove is set such that the pin is located at the outer end of the elongated groove and the pin is located at the inner end of the elongated groove when the handle is pulled out.

(e) Effects of the invention According to this invention, since the support pieces of the handle described above are connected in a cross shape, the foldable handle can be mainly composed of only two parts, and as a result, the number of parts can be greatly reduced. In order to reduce
This has the effect of reducing assembly man-hours.

Moreover, when the above-mentioned handle is pulled out and the grip part is grasped when pouring water, the above-mentioned pin is located at the inner end of the long groove on the body ring side, so the retracting operation of the handle is blocked, and therefore the water is poured. This has the effect of ensuring the stability of the insulating water bottle during times.

In addition, since the thickness of the pivot joint is set to about half the thickness of the support piece mentioned above, the pivot joint to which the handles are pivoted does not take up any bulk, and these handles can be compactly arranged in a cross shape. There are effects that can be linked.

(F) Embodiment An embodiment of this invention will be described below in detail based on the drawings.

The drawings show the handle folding mechanism of the thermal water bottle. In FIGS. 1 to 5, the thermal water bottle 1 is provided with an outer container 3 containing an inner container 2 therein, and the outer peripheral surface of the outer container 3 is Upper and lower body rings 4 and 5 are attached and fixed to the upper and lower ends, respectively.

A pair of left and right long grooves 6, 6' are formed at opposing positions on the lower surface of the upper body ring 4 and the upper surface of the lower body ring 5, respectively, and two long grooves 6, 6' are formed between these body rings 4, 5. The handle 7 of the set is
It is disposed in the outer container 3 so that it can be drawn out and stored.

The aforementioned handle 7 has support pieces 9, 9 extending horizontally and laterally at both upper and lower ends of a grip portion 8 extending vertically.
It is formed in a U-shape, with two symmetrical
The support pieces 9, 9 in the book handles 7, 7 are cut out approximately in the center to have a circular pivot portion 10, 1.
0' is recessed. When assembling the handle 7, as shown in FIG.
0', 10, and 10' are engaged, and at the same time, a support shaft 12 is engaged and fixed in a shaft hole 11 drilled at the center point of the pivot portion, so that the pivot shaft 12 is connected so as to be openable and closable in a cross shape.

The above-mentioned support piece 9 extends horizontally and laterally with respect to the above-mentioned shaft hole 11 to form a guide part 13, and pins 14, 14 are integrally provided at the tip of the guide part 13 so as to project outward. are doing.

In addition, stopper surfaces 15 having appropriate angles around the shaft hole 11 are cut out in the grip portion 8 and the guide portion 13, respectively, and the handle 7

contact each other to restrict rotation of the handle 7 and firmly fix the left and right handles 7 together.

The aforementioned pin 14 is slidably and loosely engaged with the aforementioned long grooves 6, 6', and when the handle 7 is folded, it slides onto the outer ends of the long grooves 6, 6' as shown in FIG. When the handle 7 is pulled out, the pin 1
4 and 14 slide toward the center in the long grooves 6 and 6' to allow the pull-out operation of the handle 7, and when the pull-out is completed, the pins 14 and 14 move to the inner ends of the long grooves 6 and 6' as shown in FIG. This contact firmly fixes the body rings 4, 5 and the handle 7 together.

The lengths of the long grooves 6, 6' mentioned above are set to predetermined lengths that enable such an operation.

In the folded state of the handle 7 configured in this way, as shown in FIG. , 14 slide on the outer ends of the long grooves 6, 6', and the grip portion 8 is held in the vicinity of the outer container 3.

Then, from the folded state shown in FIG.
To pull out the handle 8, the handle 7 rotates around the support shaft 12 of the support piece 9, and this rotation causes the pins 14, 14 to move inward through the long grooves 6, 6'. When the slide is completed and the drawing is completed, the pins 14, 14 contact the inner ends of the long grooves 6, 6' as shown in FIG. contact, handle 7, 7
The handle 7 and the body rings 4, 5 are firmly fixed to each other.

Further, in order to fold the handle 7, when the grip portion 8 is pushed down inwardly, the support piece 9 rotates around the support shaft 12 and returns to the original folded state as shown in FIG.

In this manner, when in use, the handles 7, 7 can be pulled out to safely and reliably pour water in the same manner as with a fixed handle, and when carried, the handles 7, 7 can be folded to minimize the protrusion.

In short, since the supporting pieces 9, 9 of the handles 7, 7 are connected in a cross-like manner, the foldable handle can be mainly composed of only two parts, and as a result, the number of parts can be significantly reduced. As a result, there is an effect that the number of assembly steps can be reduced.

Moreover, when the above-mentioned handles 7, 7 are pulled out when pouring water and the grips 8, 8 are gripped, the above-mentioned pins 14, 14 are attached to the inner ends of the long grooves 6, 6' on the body rings 4, 5 side. Since the handle is located at this position, the retracting operation of the handle is prevented, which has the effect of maintaining and ensuring the stability of the heat-insulating water bottle when pouring water.

In addition, since the thickness of the pivot portions 10, 10' is set to about half the thickness of the support pieces 9, 9,
The pivot parts 10, 10' to which the handles 7, 7 are pivoted
There is an effect that these handles 7, 7 can be connected in a compact cross shape without adding any bulk.
