Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a separable hinge suitable for use in supporting the opening and closing of the lid of a portable cold storage box, particularly a fishing cold box.

[Prior art] Conventionally, in a portable cold box, especially a cold box used for fishing, the body and lid of the cold box are connected to the body of the cold box by a hinge so that they can be opened and closed, and the fish, etc. that have been caught can be stored directly inside the body. The inside of the cold storage box is heavily soiled with fish odor, scales, and other filth, and if left unattended, the odor becomes strong and it tends to become unclean, so it must be washed with water after use. When the lids are connected by a hinge, the object is larger and a larger washing area is required than when the lids are separated, and the lids become clumsy and difficult to wash, making it difficult to completely clean them. To solve this problem, the main body and the lid can be separated by making it possible to separate the hinge that connects the cold box body and the lid. Separable hinge was developed in 1977.
Those disclosed in Japanese Utility Model Publication No. 71672 and Japanese Utility Model Application Publication No. 58-168670 are known.

[Problems to be solved by the invention] However, in the case of the one disclosed in Japanese Utility Model Application Publication No. 57-73672, in order to separate this, a hole in the center of the hollow rotating portion provided in each plate member is inserted. This is because the tongue-like holding part or the pin-like engaging part provided on one side end of the coupling shaft to be engaged is disengaged from one plate member and then pulled out in the axial direction to completely separate them. ,
The connecting shaft that connects the cold box body and the lid is separated into three points,
Since the connecting shaft is much smaller than the main body and lid of the cold box, there is a risk of powder loss if you are not careful when storing it. It was hot.

In addition, in the case of the one disclosed in Japanese Utility Model Application Publication No. 58-168670, as shown in FIG. Fit the hinge pin f' into the pin holes c, c', c', and
Parallel to c' and c', a regulating groove d equivalent to the above pin hole
is provided, and a retaining member f'' is fitted therein, and the retaining member and the hinge pin f' are bent at a connecting portion f to form an integral structure, and the retaining member f'' is opposite to the connecting portion f side. When the hinge pin f' is pulled out in the direction of the arrow in FIG. 4 to form a retaining part g on one end side, and the cold box main body and the lid body can be separated, the retaining member g is locked in the regulating part e of the regulating groove and the hinge pin
f' is held by the first hinge plate member a. Although this configuration solves the problem of loss of hinge pin f′,
Since f' moves smoothly between the pin holes c, c', c' and the regulating groove d, the parallelism of the pin hole and the regulating groove and the parallelism of the hinge pin f' and the retaining member f'' are the same accuracy. In particular, it is necessary not only to ensure that the parallelism between the hinge pin f' and the retaining member f'' does not become distorted during use, but also to ensure that the parallelism between the hinge pin f' and the retaining member f'' is approximately 2 It is uneconomical because it requires the main component material of the hinge pin f', and the retaining part e of the hinge pin f' is
If an attempt is made to form the hinge member so that it is left and right symmetrical, locking grooves e will be formed on both sides, which will inevitably result in an unnecessary hole on one side, which will cause problems in terms of appearance. Ta.

The present invention solves the above-mentioned conventional problems, and facilitates the separation and connection of both hinges without completely separating the hinge plate members and the hinge pin, and without the need for parallelism.
To provide a separable hinge for a cold box that can be completely symmetrical without any defects in appearance.

[Means for Solving the Problem] That is, the present invention provides shaft bearings 3 and 4 that are provided so as to be able to engage with each other on a pair of hinge components 1 and 2 that are screwed onto the main body and lid of a portable cold storage box, respectively. , 4 each shaft hole 3
a, 4a, 4a in the axial direction so as to be freely inserted into and removed from the shaft 5 to pivotally connect and separate the above-mentioned components.
In the separable hinge, a pair of recesses 9 are provided at both ends of the back surface of one of the hinge components, and one of the recesses accommodates a latching member to be latched to the pivot, and a pivot member is provided at the tip of the pivot. the spring hook part 8,
A lever 6 is attached to the base end,
This solved the above problems.

[Example] The drawings showing the embodiment of the present invention will be described in detail below. Figs. 1 to 3 show an embodiment of the separable hinge according to the present invention, and Fig. 5 shows an embodiment of the separable hinge according to the present invention. This shows an example in which such a separable hinge is used to support the opening and closing of the main body and lid of a portable cold box.
21 is the container body constituting the portable cold storage box, and 21 is the lid.
It is fixed to the container body 20 so as to be openable and closable.

The above-mentioned separate type hinge F is a hinge component 2 attached to the container body 20 as shown in FIGS. 1 to 3.
and a hinge component 1 that is attached to the lid, each of which is screwed onto the container body and lid through screw holes provided at appropriate locations, and these components 1 and 2 are integrally formed from synthetic resin or metal material. and
The hinge component 1 has a protruding shaft bearing part 3 formed at the center of its one end edge, and the hinge component 2 has a pair of shaft bearing parts 4, 4 formed on both sides of its one end edge, into which the shaft bearing part 3 can be fitted from both sides. , each of these bearing parts 3, 4,
Each central axis of 4 has a shaft hole 3 whose axes coincide with each other.
a, 4a, 4a are bored, and the hinge components 1, 2 can be connected to each other by fitting a pivot 5 into the shaft holes 3a, 4a, 4a from one shaft hole.

The pivot 5 is provided with a spring hook 8 on its distal end side to prevent it from falling off the hinge component 2, and a lever 6 is integrally provided at the base end of the pivot 5, and a metal material is machined into the pivot 5. A spring hanging portion 8 is formed by, for example, the lever 6, and the lever 6 is integrally molded from synthetic resin. The first spring hook part 8 is formed by cutting the end side of the pivot shaft 5 at right angles to the axis line to form a thin diameter straight part, and then expands in diameter in an inclined manner toward the lever part 6 to become the outer diameter part of the pivot shaft 5. It has been formed. A recess 9 for receiving the stop spring 10 that engages the spring hook 8 formed in this way is
A pair of long openings are provided on both sides of one end edge of the back side of the hinge component 2 in a direction substantially perpendicular to the axis of the shaft hole 4a. The stop spring 10 is housed in a recess 9 on the side of the pivot 5 that is in contact with the lever 6 of the two recesses 9 provided in the hinge component 2. The stop spring 10 is located in the recess 9, and one end 10a of the stop spring 10 is elastically biased so as to press the pivot shaft 5 in a direction substantially perpendicular to the axis. As shown in FIG. 3, when the spring hanging part 8 provided at the distal end of the pivot 5 moves the axis in the axial direction, one side thereof is made a vertical hanging surface 8a, so that one end 10a of the stop spring 10 is The structure is such that the pivot shaft 5 is prevented from moving further in the axial direction from the hinge component member 2, and is prevented from falling off. In the embodiment, the stop spring 10 is formed by winding a spring wire material and connecting both ends 10a and 10b.
It is formed to have spring properties by extending symmetrically, and its one end 10a is bent upward in a substantially perpendicular direction to exert a bending force that presses the pivot in a direction substantially perpendicular to the axis. The other end 10b is assembled so as to be hooked to a corner of the recess 9 and placed inside so that it will not fall off.
3 and 23 are screwed into the appropriate locations on the cold box body.

When the pivot 5, which is hooked to prevent it from falling off, is pushed in the direction of arrow A in FIG.
A is moved and pressed by the tapered surface 8b to the outer periphery of the shaft, moves in a direction perpendicular to the shaft center while receiving a spring force, and when the lever part 6 reaches the entrance of the shaft hole of the hinge component 2, the movement of the shaft stops. .

Further, when the pivot shaft 5 is fitted and removed, the force applied by the stop spring 10 in the axial direction of the pivot shaft 5 causes the pivot shaft 5 to
is located in the hinge component 2, so it does not move freely and does not cause rattling between the shaft hole and the shaft. Further, the recess 9 for accommodating the stop spring 10 is narrow enough to accommodate the stop spring 10 without moving in the axial direction.

[Effect of the invention] With the structure as described above, a spring hook part is integrally provided on the pivot that is removably inserted into the shaft hole of the hinge component of the detachable hinge for a cold box according to the present invention, and the spring hook is One end of a retaining spring installed in a recess provided on one side end of the back surface of the hinge member is engaged with the retaining surface of the spring retainer, thereby preventing the pivot from moving in the axial direction. When used to attach the box body and lid, the pivot will not come off when opening/closing the lid or during other uses, and the cold box body and lid shall be held together until the hinge function is reliably achieved. Even in the separated state, the pivot will not fall off from the hinge component and become a separate body, so there is no need to worry about losing it. Furthermore, since the pivot part and the latching part are not made by bending a single shaft rod, there is no need to ensure the accuracy of parallelism between the pivot part and the latching part, and there is no need to ensure the accuracy of the parallelism between the pivot part and the latching part. There are no matching holes and the hinge members can be formed symmetrically, so there is no need to separately mold the hinges for the left and right sides of the cold box, and the molds for both the left and right hinge components are made in one mold It is possible to manufacture the length according to the mold. When assembling into the cold box, the internal position of the spring is determined by the insertion direction of the pivot, and since the direction can be freely selected, assembly is easy. Furthermore, since the lever part of the pivot is not provided with a function such as a latching means or any other special function, when forming the lever, it is possible to give flexibility in color tone and shape. It has a special effect.
