Description

  The present invention relates to a cutting tool for a water-retaining foamed resin block for ikebana, which is provided in the market as a rectangular parallelepiped shape having a predetermined size as a convenience for marketing, and more specifically, by a single cutting operation, It is related with the cutting tool of the water retention foam resin block for flower arrangements devised so that the water retention foam resin block of the use unit size of this can be created at once.

  The water-retaining foam block for ikebana is a foamed material of urea resin-based resin material. By inserting water into this and inserting cut flowers that are fresh flowers, the posture of the cut flowers is maintained in the inserted state. As well as being able to supply water to cut flowers for a certain period of time without the need for water containers such as vases and basins, it is possible to create a large number of bouquet packaging as a preparation for selling fresh flowers outside of ordinary household use In addition, it is frequently used for timed use such as ceremonial occasions.

  In addition, the water-retaining foam resin block for ikebana is provided to the market as a rectangular block with a sales unit size, and the user cuts the purchased block into a desired use size and uses it. Yes. By the way, the water retentive foam resin block for ikebana is like a so-called sponge in appearance, and therefore has a property similar to a sponge in handling, but has a property completely different from that of a normal sponge. Is a special material.

  Such special properties pose the following problems with respect to the cutting operation of the water-retaining foamed resin block prior to use. For example, the water-retaining foamed resin block has a property that the frictional force is extremely large and the cutter knife cannot be moved at a slightly cut position even if it is cut with a cutter knife. On the other hand, elasticity and resilience are almost none and extremely brittle. Therefore, if the cutter knife or the like that has stopped moving is forcibly moved, the material in the vicinity of the knife is attracted to the knife and collapses so as to buckle. In addition, it is lightweight and easily misaligned during cutting, and if it is held with bare hands, there is a problem that the corners are rounded or dented into a finger shape.

The above-mentioned problems related to the cutting of the water-retaining foamed resin block are not so inconvenient when used at a low frequency in general households. Cutting a water-retaining foamed resin block when a large number of products are used as a part of a product at a high frequency is a complicated burden that requires an extremely long time and effort. Therefore, in florists and the like, a cutting tool that can easily cut the water-retaining foamed resin block is desired. However, as shown in the following patent document, despite the gradual increase in proposals regarding the use of the water-retaining foamed resin block, an appropriate cutting tool is not provided.

  Even though the water-retaining foam block is cut and used, it seems that it is too easy to provide an appropriate cutting tool, so there is no need to develop a dedicated cutting tool. In some cases, it may be determined that it is sufficient to cut with a conventional blade or the like. However, as a result of actually performing a cutting operation with a common tool (for example, a cutter knife, a yarn saw), the cutting seems to be easy, but it is not an easy operation.

  The present invention has been made as a result of the inventors paying attention to the fact that the relationship between the blade and the material when cutting the water-retaining foamed resin block is very similar to that when cutting cheese or clay. That is, when cutting clay or the like with a blade, the blade stops moving when the blade edge is slightly cut into the clay or the like, and if the blade is forcibly moved, the material collapses. Such a phenomenon is the same as the relationship between the water retention foamed resin block and the blade. However, there is a fact that it can be easily cut in addition to pressing a thread stretched with a constant tension against clay or the like. This is because the yarn does not have enough area for friction to work.

  The present invention aims to provide a cutting tool that can easily take a large number of pieces in a very easy and short time without losing shape of the water-retaining foamed resin block for ikebana, based on this as a hint. To do.

  The present invention employs the following means in order to solve the above problems.

A square frame-shaped guide frame having square holes of vertical and horizontal dimensions corresponding to the vertical and horizontal dimensions of any one of the water-retaining foamed resin blocks for flower arrangement provided as a rectangular parallelepiped shape of a predetermined dimension, and a guide around the guide frame A reinforcing frame formed in a direction orthogonal to the frame, a pair of left and right handles formed directly or via the reinforcing frame, and either or both of the guide frame and the reinforcing frame A plurality of positioning grooves for positioning by inserting the cutter wire, and a cutter wire extending in the positioning groove so as to cross the square hole of the guide frame vertically and horizontally. Place the guide frame on the water retentive foam resin block so that the water retentive foam resin block is positioned by the hole, and push down the pair of left and right handles with both hands to pass the water retentive foam resin block into the square hole of the guide frame. By, in stretched the separating tool water retention foamed resin blocks for flower arranging via the cutter line to straw cutter simultaneously water retention foamed resin blocks for the vertical direction and the horizontal direction, the upper end surface of the guide frame A plurality of positioning grooves into which the cutter wires are fitted, and a hooking groove that allows the cutter wires to be hooked at positions corresponding to the positioning grooves are arranged in parallel on the reinforcing frame, and each cutter wire is made of nylon thread. is formed, said the two positions of the cutter wire, said mounting crimping fittings size not pass through the hooking groove of the reinforcement frame, one side the hanging of the cutter line corresponding positions across the rectangular holes Hook the crimping fitting on one side to the back side of the retaining groove, fit it into the positioning groove and the positioning groove on the other side from the retaining groove on one side, and then on the other side to the lower side of the retaining groove on the other side and latching crowded Turn the crimp fitting, a plurality of Each cutter lines is characterized in that separately hooking possible constructed.

  The cutting tool for the water retentive foam resin block having the above-described configuration positions the water retentive foam resin block by the guide frame by making the size of the square hole of the guide frame correspond to the dimension of one surface of the water retentive foam resin block. In addition, because it uses a cutter wire push-cut method, there is no need to hold the water-retaining foam block by hand during the cutting operation. Cutting work can be performed, and problems such as corner dropping of the water-retaining foamed resin block due to pressing by hand do not occur. At this time, since the guide frame advances while positioning the water-retaining foamed resin block in the square hole, it is possible to prevent the cut surface from being bent. The reinforcing frame formed in a direction orthogonal to the guide frame gives a three-dimensional structure to the guide frame and can withstand the force applied during the cutting operation. Moreover, the cutter wire is attached in the vertical direction and the horizontal direction, so that the water-retaining foamed resin block can be cut simultaneously in the vertical direction and the horizontal direction.

When attaching the cutter wire, by selecting the positioning groove provided in advance at the predetermined position and the corresponding retaining groove, the labor to measure the extending position of the cutter wire each time can be omitted and the size to be used The cutting size can be easily changed by selecting the latching grooves and the positioning grooves corresponding to each other . And the cutter wire is made of nylon thread, and the crimping fittings that cannot pass through the latching groove are fixed in two places, and a finger loop is formed on one end, so one side of the latching groove is on one side Attach the crimping bracket to the back side of the wire, put your finger on the finger loop, fit it into the positioning groove while applying tension to the cutter wire, fit it into the positioning groove on the other side, and attach the crimping bracket on the other side to the other side. By wrapping under the stop groove and hooking it on the back surface side, the operation of connecting the cutter wires can be omitted easily, for example, the cutter wires can be stretched one by one by a series of operations .

  The cutting device for water-retaining foamed resin blocks for flower arrangements according to the present invention is difficult to cut with a general blade by passing the water-retaining foamed resin block through a guide frame in which cutter wires are stretched vertically and horizontally. The water-retaining foamed resin block can be cut and broken very easily by the pushing operation of the cutter wire, and can be cut efficiently in a short time.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The cutting tool 50 of the water-retaining foamed resin block B includes a guide frame 51, a reinforcing frame 52, handles 53, 53, and a pair of left and right cutter wires S, S ... (FIGS. 1 and 2). .

The guide frame 51, the reinforcing frame 52, and the pair of left and right handles 53, 53 are integrally formed from a resin material having high mechanical strength such as ABS resin or polycarbonate resin. The guide frame 51 is formed in a square frame shape corresponding to a case where a plate material having a constant width is bent into a rectangle, and therefore, a square hole H <b> 1 is formed inside the guide frame 51. The vertical and horizontal dimensions of the square hole H1 are set so as to slightly exceed the vertical dimension X and the horizontal dimension Y of any one surface B1 of the water-retaining foamed resin block B to be cut (FIG. 1). . On the upper end surface of the guide frame 51, a large number of positioning grooves 5A1, 5A1,. Each positioning groove 5A1 is a V-shape, a number of lock grooves 5A2,5A2 ... are arranged to correspond to each other across the rectangular hole H1, lock grooves 5A2 is a V-shaped as well.

The reinforcing frame 52 is formed over the entire circumference of the guide frame 51 in the form of a reinforcing rib that protrudes to the side of the guide frame for the purpose of giving the guide frame 51 a three-dimensional structure. Therefore, the guide frame 51 and the reinforcement frame 52 have an orthogonal angular relationship. Further, handles 53, 53 are integrally formed on the left and right reinforcing frames 52 corresponding to the short sides of the guide frame 51. Although the boundary between the reinforcing frame 52 and the handle 53 is not clear, there is no problem in handling the cutting tool 50. The reinforcing frame 52 has at least the number of retaining grooves 5A2, 5A2,... Corresponding to the positioning grooves 5A1 , 5A1 formed in the guide frame 51. The left and right handles 53, 53 are formed with through holes H 2, H 2 for allowing the cutter wire S to pass therethrough, and the latching grooves of the reinforcing frame 52 corresponding to the positioning grooves 5 A 1, 5 A 1 on the short side of the guide frame 51. 5A2 and 5A2 are formed inside through holes H2 and H2. The handles 53, 53 can be provided separately from the reinforcing frame 52.

  As the cutter wires S, S... In the present embodiment, two crimping metal fittings 56, 56 are attached and a finger loop S1 is formed at one end (FIGS. 1 and 3). The cutter wire S is diverted from fishing / fishing teg, that is, nylon thread. For each cutter wire S, positioning grooves 5A1, 5A1,... And latching grooves 5A2, 5A2,... At the corresponding positions across the square hole H1 are selected, and the crimping fitting 56 on one side of the cutter wire is attached to the retaining groove 5A2 of the reinforcing frame. The other side of the cutter wire is detachably attached in a state where the other side of the cutter wire is hooked on the back side of the corresponding locking groove 5A2.

The cutter wire S provided with such crimp fittings 56, 56 can be stretched on the guide frame 51 by a series of operations (FIG. 3). Each cutter wire S is attached by hooking one of the cutter wires to the back surface side of the retaining groove 5A2 of the reinforcing frame 52 and fitting the intermediate portion into the positioning groove 5A1 on the upper end side of the guide frame 51, It is completed by putting the finger on S1 and pulling it to the other side, and turning the remaining crimping fitting 56 below the retaining groove 5A2 of the other reinforcing frame 52 while fitting it into the positioning groove 5A1 on the other side. Each crimping fitting 56 has a brim 5T having a high latching effect, but if it is a size that cannot pass through the latching groove 5A2, a normal crimping sleeve without the brim 5T is used. It ’s enough.

  The cutting tool 50 shown in the present embodiment can be used very easily in the following manner (FIGS. 1 and 3). The cutter lines S, S... Are stretched one in the vertical direction and three in the horizontal direction, and the square hole H1 of the guide frame 51 has eight equal-sized grids by the cutter lines S, S. It is divided into.

  The water retaining foam resin block B is placed with the surface B1 of the corresponding shape of the square hole H1 of the guide frame 51 facing up, and the water retaining foam resin block B is positioned on the square hole H1 and then cut. The tool 50 is mounted. Next, the entire cutting tool 50 is pushed down so as to put the weight on both the left and right handles 53 and 53. Even if the person is light, place both hands on the left and right handles 53, 53 while tilting them slightly to the left while placing the weight on the guide frame 51, then tilting them to the right and swinging them alternately. As a result, the cutting tool 50 is pushed down. As a relative movement of this operation, the water retaining foam resin block B rises in the square hole H1 of the guide frame 51, and the cutter wires S, S... Bite into thin lines and are pushed into the water retaining foam resin block B. It will be cut and destroyed.

  As a result, the water retaining foam resin block B is cut and broken into eight water retaining foam resin blocks having a desired size. In the cutting operation, an upward reaction acts on the cutter wires S, S..., But each cutter wire S is hooked on a reinforcing frame facing sideways with respect to the guide frame 51. The cutter lines S, S... Do not drop out.

Regardless of the above-described embodiment, the cutting tool 50 may not include any one of the guide frame 51 and the reinforcing frame 52, or the positioning grooves 5A1, 5A1,. This is because the cutter lines S, S... In this case need only be tied to the guide frame 52. This also applies to the crimping fitting 56 and the finger loop S1. This is because they do not contribute to the basic operation of the cutting tool 50 but are intended to make the cutting tool 50 more convenient.

  Further, the guide frame 51 and the reinforcing frame 52 can be easily implemented as a sheet metal processed product of metal material or as a die-cast product. Regarding the material of the cutter wire S, not only the nylon wire but also a metal wire having a thickness of about 18 to 22 can be used to obtain the same cutting action. However, in the case of a metal wire, slack is likely to occur in a drawn shape, and it is necessary to adjust the tension every time it is used.

  In the above description, it has been described that the cutting tool 50 is cut by passing the cutter wire S so that the water retaining foam resin B is inserted into the guide frame 51, but conversely, the cutter wire S side is water-retained. It can also cut | judge along the guide frame 51, making it contact with the property foam resin B and pushing in so that the cutter wire S may bite into the water retention foam resin B. FIG.

It is a perspective view which shows embodiment of this invention. It is a top view of the principal part in the said embodiment. It is sectional drawing of the principal part in the said embodiment.
