[0011]

[Embodiment of the invention]

 Next, an embodiment of the hanging case according to the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an embodiment in which the hanging case 10 according to the present invention is applied to a key ring. The hanging case 10 is of a detachable type, and includes a main body 30 and a component mounting portion 40 for storing a key 48 as a component by being screwed to the main body 30.

As shown in the figure, the main body 30 has a substantially bell-shaped shape as a whole, and is wound tightly in a coil shape by a predetermined number of turns so as to be entirely bell-shaped. For this reason, a steel material having a spring property, for example, a stainless steel wire (SUS 304 WPB) having a wire diameter of about 2 mm is used and tightly wound to form the main body 30.

An example of the size of the main body 30 will be described below. The inner diameter Da of the threaded portion at the open end 34 of the main body 30 is 16.7 mm, and the inner diameter Db on the top side of the main body 30 is 4 mm. The length La of the entire body is 26 mm, and the number of turns (the number of turns) of the stainless steel wire is 14 at this time.

At a predetermined position of the main body 30, a projecting portion 32 serving as a stopper described later is formed. The protruding portion 32 is formed by pressing a part of a stainless steel wire and protruding slightly inside the main body 30 into a mountain shape as is apparent from FIG.

On the other hand, as shown in FIG. 1, the component mounting portion 40 is formed by winding several turns, in this example, two turns, with an outer diameter Dc that can be screwed to the inner diameter Da of the main body 30. , One end of which has a J-shaped part for component mounting 42 bent into a J-shape. The J-shaped portion 42 is provided with a key 48 component, and a holder hole formed in the key 48 is inserted therethrough.

The other end of the component mounting portion 40 has an engagement end portion 44 slightly protruding in a direction perpendicular to the winding direction of the stainless steel wire. The engaging end 44 functions as an engaging portion for the stopper.

Both the main body 30 and the component mounting portion 40 are made of plated or electrolytically polished stainless steel wire so as to give some luster. Both the main body 30 and the component mounting section 40 are barrel-treated so that the ends of the respective wires are rounded. If the barrel is not treated, the end may damage other objects or damage the clothing.

The wire diameter of the stainless steel wire constituting the component mounting portion 40 is 2 mmφ, the outer diameter Dc is 17.3 mm, the length of the J-shaped portion 42 is 19 mm, and the length of the engagement end portion 44 is 3 mm.

The bending length of the J-shaped part 42 is selected so that a small gap W is formed between the J-shaped part 42 and the coil-shaped part 41. The gap W is determined in consideration of the thickness of the key 48 to be stored and the like, and when the entire size is selected as described above, a gap of about 5 mm is left.

The surface of the J-shaped portion 42 is covered with a predetermined length by vinyl chloride resin, nylon, or the like. This coating 46 prevents the keys 48 to be stored from being damaged. As the above-mentioned wire rod, a piano wire, titanium steel or the like can be used in addition to a stainless steel wire.

As shown in FIG. 1, a well-known coiling machine may be used to tightly wind the stainless steel wire, so that the processing of the main body 30 and the component mounting portion 40 is simple.

When the thus constructed hanging case 10 is used as a key holder, a key 48 is first inserted into the J-shaped part 42 as shown in FIG. 1, and in this state, the part mounting part 40 is wound. The other end is screwed into the main body 30 with the other end first. Then, as shown in FIG. 3, the space between the coil-shaped linear portions 41 of the component mounting portion 40 acts as a screw thread or a screw groove, and the coil-shaped linear portion 31 constituting the main body 30 is also screwed. Since the component mounting portion 40 is pressed into the main body 30 while rotating, the component mounting portion 40 is screwed to the main body 30 to a predetermined depth. As a result, the key 48 can be attached to the main body 30.

When the component mounting portion 4 is further screwed, the engaging end portion 44 goes over the inner surface of the protruding portion 32, so that the component mounting portion 4 is locked to the main body 30. In other words, the state before FIG. 4A is reached before the engagement end 44 reaches the protrusion 32, and the state shown in FIG. When the screw is engaged as it is, the engaging end portion 44 is obstructed by the projecting portion 32. Therefore, if the component mounting portion 40 is turned with the same force as before, the engaging end portion 44 gets over the projecting portion 32. Can not. Since the coil-shaped portion 31 has a spring property, when the component mounting portion 40 is turned with a certain amount of force, the engaging end portion 44 can get over the projecting portion 32, and the overriding state is as shown in FIG. 4C. is there. Once the component mounting portion 40 has been passed over, the component mounting portion 40 cannot be removed from the main body 30 unless the component mounting portion 40 is turned with the same force as when the vehicle has passed over the projecting portion 32. Therefore, in the state shown in FIG. 4C, the component mounting section 40 can be locked to the main body 30.

When the component mounting portion 40 is screwed into the main body 30 until the locked state is reached, the end 45 of the J-shaped portion 42 slightly enters the opening end 34 side of the main body 30 as shown in FIG. No. As a result, the gap W can be completely closed by the main body 30, and the in-use key 48 does not come off from the J-shaped portion 42. Of course, in the locked state, a slight vibration is applied or the lock cannot be released by a slight reverse rotation. Therefore, there is no possibility that the key 48 comes off the component mounting portion 40 and the key 48 is lost during use. Absent.

As described above, the hanging case 10 according to the present invention has few components, is easy to process, and has a small number of assembling steps. Therefore, this type of hanging case 10 can be provided at low cost.

In addition, since the component mounting portion 40 can be securely locked to the main body 30, it is possible to prevent an accident that the mounted component comes off and is lost. Further, the conventional stopper 24 is not used. If it is desired to attach the component mounting portion 40 to a band or the like, the component mounting portion 40 may be screwed and fixed to the main body 30 with the component mounting portion 40 inserted into the band.

The size described in the above embodiment is merely an example. In the above-described embodiment, the present invention is applied to a key ring. However, it goes without saying that the present invention can be used as a hanging case for storing other light and flat parts and hanging them on a hook or the like.
