Description

  The present invention relates to a liquid next vine such as an earthen jar used in general households.

  Depending on the structure of the earthenware vine that has the vine body of the belt-shaped metal plate inserted through the coil spring, there are things that can keep the vine standing vertically with respect to the earthenware, and are made of metal. Therefore, it is still popular because it can be used almost permanently without deterioration.

  However, in the conventional product, the end of the folded portion of the vine body is inserted into a coil spring that can be expanded and contracted in a pressure contact state. Therefore, when the fingertip or the like suddenly touches the end of the coil spring and contracts the coil spring, the end of the folded portion inserted into the coil spring may pop out vigorously due to the return force of the folded portion. . For example, if a coil spring suddenly jumps out while pouring hot water contained in a clay bottle into another container, the user may be surprised by the impact and spill hot water or put it on the other hand.

  In the present invention, even when a fingertip or the like touches an end of a coil spring during use, the jar such as an earthen jar or an iron jar that can securely insert the folded portion into the coil spring without contracting the coil spring. Is to provide.

  Claim 1 of the present invention has a vine main body formed of a strip-shaped metal plate, and a coil spring that is extendable in the length direction and shorter than the vine main body, and the width of the vine main body is larger than the inner diameter of the coil spring. Shortly formed, the vine body is inserted into the coil spring, and there is a coil spring around the vine body in the gripping part, both ends of the vine body are folded back to form folded parts, and the folded parts face it. A liquid vine such as an earthen pot inserted into a coil spring in a state of being pressed so as to reduce the distance from the vine body, and a recess is provided on a side edge of at least one folded portion, and is in a pressure contact state The main body has an elastic force that can expand the inner diameter of the coil spring that is in pressure contact with the folded portion by the return force of the folded portion, and a part of the spring wire of the expanded coil spring. It is configured to engage the recess of the folded portion moves in the direction to return to the original position.

  A second aspect of the present invention is a configuration in which an element in which one concave portion is provided on each side edge of each folded portion is added to the first aspect.

According to a first aspect of the present invention, a concave portion is provided on a side edge of at least one folded portion of the vine body, and the inner diameter of the coil spring that is in pressure contact with the folded portion can be expanded by the restoring force of the folded portion in the pressure contact state. The main body has an elastic force that can be generated, and a part of the spring wire of the coil spring that has been spread is moved in a direction to return to the original position and is locked in the recess of the folded portion. Therefore, a part of the spring wire and the recessed portion of the folded portion are locked, and the folded portion can be reliably inserted into the coil spring without contracting the coil spring. Can be prevented from suddenly jumping out.

According to a second aspect of the present invention, one recess is provided on each side edge of each folded portion. Therefore, since there are two locking portions of one folded portion, it is possible to prevent the folded portion from protruding more reliably.

FIG. 1 is a use state diagram of the present invention. FIG. 2 is a front view of the present invention. FIG. 3 is a side view of the folded portion. FIG. 4 is a front view showing a state in which the folded portion is inserted into the coil spring. FIG. 5 is an enlarged cross-sectional view showing a coupled state of the folded portion and the coil spring. FIG. 6 is a side view of the folded portion showing another embodiment of the recess.

  The vine 3 includes a vine body 1 and a coil spring 2. The vine body 1 is formed of a belt-shaped stainless steel plate. A metal other than stainless steel may be used, for example, an iron plate plated with chromium or the like. The coil spring 2 is formed of a stainless steel wire. A material other than stainless steel may be used. For example, an iron wire plated with chromium or the like may be used. The coil spring 2 is formed shorter than the vine body 1. The width of the vine body 1 is shorter than the inner diameter of the coil spring 2, and the vine body 1 is inserted through the coil spring 2, and both ends of the vine body 1 protrude from both ends of the coil spring 2.

  The vine main body 1 is folded into a U shape, and both end portions are folded back to form folded portions 13 and 13. Both folded portions 13 and 13 are slightly opened with respect to the vertical portions 4 and 4 of the vine main body 1. Concave portions 6 and 6 are provided on both side edges 5 and 5 of the end portions of the folded portions 13 and 13, respectively. The recess 6 may be provided only on one folded portion 13. The heights of the two recesses 6 and 6 are slightly different. As shown in FIG. 5, the inner diameter of the recess 6 is formed shorter than the outer diameter of the spring wire 7, but it may be formed longer than the outer diameter of the spring wire 7. Further, the inner diameter of the recess 6 may be around twice the outer diameter of the spring wire 7. One folded portion 13 may be provided with one concave portion 6, or three or more concave portions 6 may be provided. The shape of the recess 6 is a quadrangle, but is not limited to this, and may be, for example, triangular recesses 19 and 19 as shown in FIG.

  The coil spring 2 is formed such that the winding pitch of the spring wire 7 at both ends thereof is closer than that of the other portions, and the spring wires are in contact with each other. Further, both end portions of the coil spring 2 are formed so that the inner diameter gradually increases from the middle toward the opening 16. As shown in FIG. 2, both ends 10, 10 of the coil spring 2 reach a position approximately in the middle between the end edges 11, 11 of the turns 13, 13 and the bending points 12, 12. And the holding part 9 is formed by the horizontal part 8 of the vine main body 1 and the coil spring 2 surrounding it. A bamboo pad 15 is fixed to the inside of the portion constituting the grip portion 9 of the vine main body 1. This is because the main body 1 is prevented from descending relative to the coil spring 2 when the earthen jar 14 is lifted by holding the grip 9.

  Next, a method for attaching the vine 3 to the clay bottle 14 will be described. First, the folded-back portions 13 and 13 of the vine 3 are inserted into the hanging holes 17 and 18 of the clay bottle 14 so that the clay bottle 14 can be lifted. Next, the coil spring 2 is contracted until either one of the front and rear ends 10 of the coil spring 2 comes above the end edge 11 of the folded portion 13. Next, the folding part 13 is pressed in the direction of the vertical part 4 of the main body 1 to hang the folding part 13 so that the folding part 13 can be inserted into the coil spring 2 from the end edge 11, thereby narrowing the interval between the folding part 13 and the vertical part 4. Next, the contraction of the coil spring 2 is slightly released in the pressed state, and when the end of the folded portion 13 is inserted into the coil spring 2 as shown in FIG. 5, the pressure on the folded portion 13 is released. . By doing so, the folded portion 13 and the coil spring 2 are brought into a pressure contact state by the elastic return force of the folded portion 13.

FIG. 5 is a cross-sectional view taken along a plane including the folded portion 13. Both side edges 5 and 5 of the folded portion 13 are in pressure contact with some spring wires 17 and 18 by the elastic restoring force of the folded portion 13. Since the width of the main body 1 including the folded portion 13 is shorter than the inner diameter of the coil spring 2, the end of the folded portion 13 is offset from the center of the coil spring 2 in the state of FIG. 5. More specifically, the end of the folded portion 13 is offset from the center of the coil spring 2 by a length that is about one quarter of the inner diameter of the coil spring 2. That is, the cross section in FIG. 5 is not a cross section at the center position of the coil spring 2 but a cross section at a position deviated from the center of the coil spring 2. Further, the vertical portion 4 of the temple body 1 facing the end portion of the folded portion 13 is also offset from the center of the coil spring 2 by a length of about one quarter of the inner diameter of the coil spring 2. Accordingly, the distance between the folded portion 13 and the vertical portion 4 of the main body 1 at that portion is about one half of the inner diameter of the coil spring 2. When the end portion of the folded portion 13 and the vertical portion 4 of the main body 1 opposite to the end portion are elastically pressed against the spring wires 17 and 18, the coil spring 2 is pushed and expanded at that portion, and the inner diameter is increased. The spring wires 7 and 7 which are in contact with the recessed portions 6 and 6 of the folded portion 13 are also expanded by the same amount as the other spring wires 17 and 18 if the recessed portions 6 and 6 do not exist. However, since there are the recesses 6, 6, the spring wires 1, 7 move slightly inward due to the elastic return force of the spring wires 7, 7 and are locked to the recesses 6, 6. By this locking action, even if a fingertip or the like suddenly touches the end of the coil spring 2 during use, the spring springs 7 and 7 are locked in the recesses 6 and 6 so that the coil spring 2 can be contracted. In addition, the end of the folded portion 13 can be prevented from jumping out of the coil spring 2. As shown in FIG. 6, when the concave portion 19 is formed in a triangle, the spring line below the spring line locked to the locking portion 20 also moves slightly in the direction of the concave portion 19. The locking state is strengthened. Of course, the present invention can be used for a liquid having a hanging hole other than a clay bottle.

The present invention relates to a liquid next vine formed by combining a vine main body 1 formed of a band-shaped metal plate and a coil spring 2 that is extendable in the length direction and shorter than the vine main body 1. It is possible to provide a vine that prevents the folded-back portion 13 inserted into 2 from popping out unexpectedly.
