[Detailed description of the invention] [Field of industrial application] The present invention is a clamp that holds in a closed state a side-opening case lid that opens and closes an opening on one side of the case body in an iron storage case that stores an electric iron. Regarding equipment.

[Prior Art] The conventional clamping device disclosed in Japanese Utility Model Publication No. 58-12753 includes a clamp receiver provided on the case body and a side-opening case lid that opens and closes an opening on one side of the case body. , a biasing body support part that faces a notch groove provided in the case lid from the inside, a clamp that is attached to the case lid by blocking the notch groove and that can be freely hooked on and removed from the clamp receiver, and this clamp and a biasing body support part. and a biasing body that is interposed between the case lid and the case lid and constantly biases the clamp from the inside to the outside of the case lid. The clamp is attached to the case lid with a plurality of screws. In such a clamp device, when the case lid is closed, the clamp is automatically engaged with the clamp receiver, and in this engaged state, the clamp is pushed inward of the case lid to remove the clamp from the clamp receiver. It can be removed to open the case lid.

[The problem that the idea attempts to solve]

Such a conventional clamp device requires a plurality of screws for attaching the clamp, so there is a problem that the number of parts is relatively large and the structure and assembly are complicated. Furthermore, the case lid has a notch groove, and inside the notch groove, there is a biasing body support part,
Since a plurality of screw receiving parts are formed, the shape is quite complicated. For this reason, the structure of the mold for molding the case lid is complicated, leading to high mold costs, which is a cause of high costs, and when the inside of the case lid is visible, it gives the impression that it is unsightly.
There was a problem that the product quality was easily damaged. Moreover,
The iron storage case is carried by grasping the handle provided at the top, but if the clamp is pushed inward of the case lid at that time, the clamp may inadvertently come off the clamp holder and the case lid may open. There was a risk that the electric iron would fall out of the storage case.

Therefore, the purpose of the present invention is to provide a clamp device for an iron storage case that is simple in structure and assembly, has a good appearance, ensures reliable clamping/unclamping operation, and prevents the clamp from coming off when being carried. It's about doing.

[Means to solve the problem]

The clamping device of the present invention holds a side-opening case lid, which is connected via a hinge to a case body with a carrying handle on the top and opens and closes an opening on one side of the case body, in a closed state. Applicable to the iron storage case. In order to achieve the above object, the iron storage case clamp device of the present invention includes a clamp receiver provided on the case body, and a clamp attached to the case lid and detachable from the clamp receiver. A clamp mounting hole is formed in the case lid, and a rotation prevention portion of the clamp is integrally formed therein, and a through protrusion that is loosely inserted into the mounting hole is formed on the back surface of the clamp. A stopper is provided on the distal end side of the protruding through-hole, and a spring is sandwiched between the stopper and the inner surface of the case lid.

[Effect]

A spring sandwiched between the stopper on the tip side of the penetrating protrusion of the clamp that is loosely inserted into the clamp mounting hole of the case lid and the inner surface of the case lid is in a compressed state, and the spring is placed in a compressed state so that the clamp can be moved toward the inside of the case lid. Since it is biased and held, the clamp can be attached to the case lid without the need for screws. When the case lid is closed, this clamp engages with the clamp receiver on the case body to hold the case lid in a closed state, and by pulling the clamp against the biasing force of the spring, the clamp The engagement with the receiver is released and the case lid can be opened. Therefore, even if the clamp is pushed inward of the case lid when carrying the iron storage case by its handle, the clamp will not come off from the clamp receiver. Also, since there is only one penetrating protrusion of the clamp that is loosely inserted into the clamp mounting hole, there is a risk that the clamp will rotate around this protrusion, but the case lid has an integral part to prevent rotation of the clamp. Because it was set up in
The clamp can always be held in a fixed position without adding special parts, and the reliability of the clamp's engagement and disengagement operations can be guaranteed.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In Fig. 1, 1 is a case body, and 2 is a case lid that opens and closes an opening on one side of the case body 1.The case body 1 and the case lid 2 form an iron storage case that stores an electric iron. . In FIG. 1, reference numeral 3 designates a handle provided on the upper part of the case body 1 that can be raised and lowered, 4 an ironing board, and 5 a heat shielding member. Further, the case body 1 and the case lid 2 are connected via a hinge 6 at the opening side edge thereof, and
They are connected by a clamping device 7.

The clamp device 7 will be explained in detail below with reference to FIGS. 2 to 6.

The case body 1 is made of synthetic resin, and a clamp receiver 8 is provided at the edge of the other side wall opposite to one side wall to which the hinge 6 is attached. The receiver 8 is integral with the case body 1, and is, for example, a substantially right triangular protrusion having an inclined surface connected to the edge end face of the other side wall.

The case lid 2 is also made of synthetic resin, and an oval clamp mounting hole 9 is formed in one side wall opposite to the one on which the hinge 6 is attached, and a clamp rotation stopper 10 described below is integrated therein. is formed. In this embodiment, the rotation preventing portion 10 is formed by a U-shaped padding.
It is adapted to be placed close to the peripheral end surface of the clamp. Note that 11 in FIGS. 4 to 6 is a groove.

Further, a clamp 12 is attached to the case lid 2 and is detachable from the clamp receiver 8. In other words, the clamp 12 is an integrally molded product of synthetic resin.
For example, it has a rectangular shape, and on the back of one long side,
It is formed by providing engaging parts 13 located on both sides of the handle part 12a, providing a protrusion 14 on the back surface of the other long side, and protruding one through protrusion 15 from approximately the center of the back surface.

The engaging portion 13 protrudes beyond the case lid 2 and is adapted to be hooked onto and removed from the clamp receiver 8, and the protrusion 14 is fitted into the groove 11. Further, the penetrating projection 15 is loosely inserted into the clamp mounting hole 9. A stopper 16 is provided on the tip side of the penetrating projection 15. Note that this embodiment shows a case where a synthetic resin disk fixed to the tip of the penetrating projection 15 with a screw 17 is used as the stopper 16. And this stopper 16
A spring 18 is interposed between the clamp 12 and the inner surface of the case lid 2, and the force of the spring 18 always urges the clamp 12 in the direction of contacting the outer surface of the case lid 2.

To attach the clamp 12 to the case lid 2, first, the penetrating protrusion 15 of the clamp 12 is loosely inserted into the clamp attachment hole 9, and the clamp 12 is stacked on the outer surface of the case lid 2. As a result, the groove 11 and the protrusion 14 are fitted together. Next, after fitting the spring 18 into the penetrating projection 15 from the inside of the case lid 2, a stopper 16 is placed on the distal end surface of the penetrating projection 15, and the screw 17 is screwed into the penetrating projection 15 through the stopper 16. . Then, the spring 18 is sandwiched between the case lid 2 and the stopper 16 in a compressed state. With the above steps, the installation work of the clamp 12 is completed.

In the iron storage case having the above structure, when the case lid 2 is closed with respect to the case body 1, the case body 1 and the case lid 2 are connected by the clamp device 7. That is, as the closing operation of the case lid 2 progresses, the engaging part 13 of the clamp 12 comes into contact with the slanted surface of the clamp receiver 8 and rides on it. Immediately after the engaging part 13 rides over the slanted surface, the spring 18 The force causes the engaging portion 13 to engage the clamp receiver 8 as shown in FIG. In this case, the clamp 12 is rotated using the fitting portion between the groove 11 and the protrusion 14 as a fulcrum, and this rotation is allowed because the penetrating protrusion 15 is loosely inserted into the clamp mounting hole 9. It will be done. In this way, the case lid 2 can be held in a closed state, and in this state, the clamp 12 is held by the spring 18.
It is urged toward the inside of the case lid 2 by the force of.

Therefore, the iron storage case should be attached to its handle 3.
Even if the clamp 12 is pushed inward of the case lid 2 when it is held and carried, the clamp 12 will not come off from the clamp receiver 8. For this reason, the case lid 2 may suddenly open when you carry it around.
There is no fear that the electric iron housed in the case body 1 will fall off.

In addition, in order to open the case lid 2, put your finger on the handle part 12a of the clamp 12, and then
The case cover 2 may be rotated about the hinge 6 by lifting it up so as to rotate it about the protrusion 14 to remove the engaging part 13 from the clamp receiver 8 .

In addition, in the clamping device 7 having the above structure, the clamp 12 is attached at one place in the center of the back surface, and even though there is play between the clamp attachment hole 9 and the through protrusion 15, , since the position of the clamp 12 is restricted by the rotation stopper 19, the position of the clamp 12 relative to the case lid 2 is restricted.
2 will not be rotated carelessly. For this reason,
The clamp 12 is always provided at a fixed position, and the predetermined positional relationship with the clamp receiver 8 is not impaired, so that the clamp 12 can be reliably engaged and removed from the clamp receiver 8.

In addition, in the present invention, when the clamp 12 has a rectangular shape as in the above embodiment, the rotation stopper 10
should be provided close to at least one end surface of the clamp 12, and if a rib or the like is provided on the back surface of the clamp, not only on the end surface of the clamp 12, it should be placed close to the rib or the like so that it is not visible. There is no problem in setting it up. Furthermore, in the present invention, the engaging portion 13 of the clamp 12 may be formed in the shape of a claw with an inclined surface, and the clamp receiver 8 may be formed in a groove.

Further, although a coil spring is used as the spring 18 in the above embodiment, a plate spring may be used instead. When using a leaf spring, the penetrating protrusion 15
The stopper 16 may be provided integrally with the leaf spring. In this case, the leaf spring is provided with a non-circular hole passing through the stopper 16, and the leaf spring can be removed from the stopper 16 by rotating the leaf spring by, for example, 90 degrees after insertion. formed to be stopped. Further, in the present invention, the clamp attachment hole 9 may be a circular hole having a larger diameter than the through protrusion 15, and the groove 11 and the protrusion 14 may be omitted.

In addition, when implementing the present invention, unless it is contrary to the gist of the invention, the specific structure, shape, and position of the clamp receiver, clamp, clamp mounting hole, rotation stopper, through protrusion, stopper, spring, etc. Of course, the materials and the like are not limited to those of the above embodiment.

[Effect of idea]

According to the present invention configured as described above, the clamp can be attached to the case lid without the need for screwing, so the number of parts can be reduced compared to the conventional method, and the structure and assembly can be simplified. It's easy to do. Also, there is no need to provide a screw receptacle for mounting the clamp on the case lid.
Moreover, since the spring support is carried by the case lid itself and a part of the clamp, there is no need to form a special spring support part on the inner surface of the case lid. Therefore, the inner structure of the case lid is simplified, and even when this inner side is visually recognized, it is possible to prevent an unsightly impression from being given. In addition, since the clamp is biased inward by the spring, even if the clamp is pushed inward when carrying the case by its handle, the clamp will not move. This prevents the iron from coming off the clamp holder, preventing the case lid from being opened inadvertently and the electric iron from falling off as a result. Furthermore, the clamp is
Although it is attached to the case lid at a certain point and its penetrating protrusion is provided so that it can be rotated by loosely inserting it into the clamp mounting hole, it is always kept in the fixed position by the rotation prevention part that is integrated with the case lid. Because it is retained,
The reliability of clamp engagement/disengagement operations can be guaranteed.
