Cutting tool for water-retaining foamed tree moon block for ikebana

TECHNICAL FIELD The present invention is marketed in a rectangular parallelepiped shape having predetermined vertical, horizontal and height dimensions as a commercial unit.

Water-retaining foam resin block for ikebana to cut the provided water-retaining foam resin block for ikebana into an appropriate size for use according to the type and usage of ikebana.

This is related to the cutting tool for sushi.

Background Art Fresh flowers have a soothing natural decorative effect not found in man-made ornaments. The so-called ikebana convention is one of the methods of expressing the traditional view of static nature in Japan. It is not limited to “flower arrangement” but also exists worldwide. Fresh flowers are used not only as a flower arrangement material, but also as an object material to be displayed daily in ordinary households, as a decorative material for business use in hotels, etc., and as a natural decoration material for festivals such as ceremonial occasions. ing. Fresh flowers as decorative materials are supplied to general consumers from the production area through the fresh flower market, retail stores, etc. as cut flowers separated from the roots, and used for each purpose. With regard to fresh flowers that are cut flowers, the maximum freshness on both the supplier and the customer side is that they can maintain their freshness for a long time in the distribution process and the usage process for each application. It is also a matter of concern and requires careful handling. Water-retentive foam resin block for ikebana makes it extremely easy to handle fresh flowers in various situations It is a foamed resin material provided to the market for the purpose of making it easy. This water-retainable foamed resin block is a foamed material based on urea resin, and is externally equivalent to a normal sponge, which is a highly elastic resin foamed material. It has both properties.

That is, the water-retaining foamed resin block for ikebana has a high water-retaining property like a sponge and exhibits a high frictional force against foreign matter. On the other hand, there is no elasticity at all, and when an external force exceeding a certain limit is applied, this part has the property of locally buckling and collapsing. Therefore, by inserting water into the water-retaining foamed resin block and inserting cut flowers, the posture of the cut flowers can be maintained while supplying moisture to the cut flowers. Therefore, the freshness of cut flowers can be maintained without using a water container such as a vase or a basin, so you can enjoy ikebana in any container at home, and bouquet packaging as a preparation for selling fresh flowers. It is often used for creation and timed use at ceremonial occasions.

The above-mentioned water-retaining foamed resin blocks for ikebana have a reason that the usage size required by customers at the time of use is not constant, and that handling in the distribution process is complicated if cut in advance. It is assumed that a rectangular parallelepiped shape that is significantly larger in length, width, and height as compared to the usage size will be provided as a sales unit, and that the user will cut the usage size according to the usage situation. Has been.

However, the special properties of water-retaining foam blocks for flower arrangements raise the following problems in the cutting work. For example, when cutting with a cutter knife or a knife with a thin blade, the cutter knife etc. will not move due to the strong frictional force of the water-retaining foamed plastic block at a slightly cut position. The material collapses as it is pulled into the knife and buckles. Also, when cutting, bare hands There is also a problem that the corners of the part that is pressed down collapse and become rounded or dent into the shape of a finger.

As a tool for cutting such a water-retaining foamed resin block for ikebana or a tool that is used as an auxiliary tool for cutting, Japanese Utility Model Publication No. 3 0 3 8 8 6 2 Japanese Patent Laid-Open No. 2 ◦ 0 3— 9 4 3 8 1 In the former, the so-called thread saw blade is replaced with a hard wire such as piano wire, and it requires skill to make the cutting surface flat, and in order to cut out the desired size, Usually, it is necessary to repeat the cutting operation several times in the vertical and horizontal directions, and the remaining part of the water-retaining foam block that is being held down by hand will lose its shape. The latter is a ruler for guides when cutting a water-retaining foam block using a normal saw, and the cutting work proceeds exactly along the ruler, saving the cutting work itself. Or it cannot be rationalized.

Further, although it is not intended to cut the water-retaining foamed resin block, it is considered that the characteristics considered to be related to the invention of the present application as a way of thinking are as follows. Gazette · US Patent No. 1, 3 3 1, 7 86 exists. Both have a common feature in which a thin metal wire is stretched vertically and horizontally on the guide frame. The former aims to cut the tofu block into many pieces of the same sales size at once, and the latter The purpose is to cut cheese or butter blocks into many pieces of the same sales size.

The sales size of tofu and butter will normally be constant, so it seems that it is not necessary to change the cutting size frequently. However, in observing the above technical contents from the viewpoint of whether or not the cutting size can be freely changed in relation to the invention of the present application, the explanation of the former is not clarified, but at least Take the thin metal wire The cutting size can be changed if there is enough effort to remove and re-install. For the latter, remove the tension mechanism on the left and right sides of the guide frame that applies tension to the stretched metal wire, and remove the single metal wire stretched on the guide frame so that it is bent back and forth in a zigzag manner. It can be said that the cutting size can be changed if there is no troublesome work that involves changing the interval between the thin metal wires and re-zigging the metal wires.

The present invention is a cutting tool for cutting by a method in which a water-retaining foamed resin block is pushed by a cutter wire made of a metal or resin fine wire stretched vertically and horizontally on a guide frame, the number of pieces to be cut and the size to be cut. For example, the number of ikebana to be produced, the type and number of ikebana used at that time, etc., so that it can be changed very easily depending on the number and size of the bouquets when adjusting the bouquet. The purpose of this is to provide a cutting tool for water-retaining foam resin blocks for ikebana. Disclosure of the invention

The cutting tool for water-retaining foam resin block for ikebana of the present invention is a rectangular hole of vertical and horizontal dimensions corresponding to the vertical or horizontal dimension of one surface or the horizontal displacement of one of the water-retaining foam resin block for ikebana provided in a rectangular parallelepiped shape of a predetermined dimension. A rectangular frame-shaped guide frame, a reinforcing frame formed around the guide frame in a direction orthogonal to the guide frame, a pair of handles formed directly on the guide frame or integrally with the reinforcing frame, At least one vertical cutter line that stretches the square hole of the guide frame along the longitudinal direction of the guide frame with respect to the guide frame, and the direction that crosses the square hole along the width direction It is composed of at least one transverse cutter line to be stretched.

DESCRIPTION OF EMBODIMENTS Embodiments of a cutting tool for water-retaining foamed resin block for ikebana of the present invention will be described with reference to the accompanying drawings.

In the preferred embodiment of the present invention, a cutting tool 50 for water-retaining foamed resin block for ikebana is composed of a guide frame 5 integrally formed from the same resin material, a reinforcing frame 6, a pair of handles 7, 7 and It consists of a longitudinally cut cutter wire S 1 stretched around the guide frame 5 and a plurality of transverse cutter wires S 2... (FIGS. 1 and 2).

As the resin material for forming the guide frame 5 and the like, materials having high mechanical strength such as ABS resin and polycarbonate resin are used. However, the guide frame 5 or the like can be implemented as a die-cast aluminum alloy or zinc alloy, or can be implemented as a plate product.

The guide frame 5 is a square frame equivalent to a strip material with a certain width bent into a rectangular parallelepiped shape. As a result, a square hole 5 H is formed inside. The dimensions of the guide frame 5 are set so that the vertical and horizontal dimensions of the formed square hole 5 H are slightly larger than the vertical dimension X and the horizontal dimension Y of any one surface of the water-retaining foam block B to be cut. (Fig. 1).

The reinforcing frame 6 is formed in a rib shape on the outer surface of the guide frame 5 so as to surround and surround the guide frame 5, that is, in a direction perpendicular to the guide frame 5. A pair of handles 7 and 7 are formed on the reinforcing frame 6 at a position corresponding to the pair of short sides of the guide frame 5 so that the width of the reinforcing frame 6 is enlarged. Therefore, there is no boundary between the reinforcing frame 6 and the handles 7 and 7 at these two locations. It is more convenient to install the handles 7 and 7 with a force that can be provided separately from the reinforcing frame 6. A through hole 7 H is provided at the center of the width of each handle 7.

On the upper end surface of the guide frame 5, a large number of positioning grooves VI are engraved at corresponding positions in the vertical and horizontal directions with the square hole 5H in between, and the reinforcing frame 6 is provided with each positioning groove VI. Corresponding latching grooves V 2… are engraved. Therefore, in any corresponding position, these are arranged on one line in the order of the lateral latching groove V 2, the upward positioning groove V I, the upward positioning groove V I, and the lateral latching groove V 2. The short side latching grooves V 2 and V 2 provided with the handles 7 and 7 are formed inside the through holes 7 H and 7 H.

As the longitudinal force cutter wire S 1 and the transverse force cutter wire S 2, a resin wire such as a metal fine wire or a nai-n fine wire can be used. It is also possible to mix the two. The longitudinal cutting line S 1 is in charge of cutting the water-retaining foamed resin block B in the vertical direction, and is extended between the short sides of the guide frame 5 along the length of the guide frame 5 in the longitudinal direction. The Also, the transverse force cutter wire S 2 ... is responsible for cutting the water-retaining foamed resin block B in the lateral direction. A plurality of cables are stretched along the short side direction of the lid frame 5.

In the present embodiment, a thin metal wire is used as the longitudinal cutter wire S 1, and a nylon thin wire is used as the transverse cutter wire S 2. Three transverse cutter wires S2 ... are stretched at regular intervals, and can be used for cutting water-retaining foamed resin block B into eight small block B1 ... of equal use size. However, when cutting the water-retaining foamed resin block B, whether or not to use the longitudinal cutter wire S1 and the transverse cutter wire S2 and how many are used are matters to be determined by the user.

The longitudinal cutter line S 1 and the transverse cutter line S 2 stretched around the guide frame 5 are both detachable. That is, a pair of stopper fittings 8 and 8 are fixed to both ends of the longitudinal cutter line S l and each transverse cutter line S 2, and a loop S for hooking a finger is formed at one end thereof. ing. These cutter wires hook one stopper fitting 8 on the back side of the hooking groove V2, and the other hooking via the corresponding positioning grooves V1, VI across the square hole 5H. It is stretched on the guide frame 5 by one operation of hooking the other stop collar 8 on the back side of the retaining groove V 2 (FIGS. 2 and 3). Therefore, each stretched cutter wire can be easily removed by one reverse operation. In addition, as the stopper metal fitting 8, a member having a collar 8T having good seating property is used, and the latched state can be stably maintained.

The cutting tool 50 according to the above embodiment is configured such that the water retaining foamed tree block B is positioned in the square hole 5H of the guide frame 5, and the longitudinal cutter wire S1 and the transverse force are pushed by pushing down the handles 7 and 7. The water-retaining foamed resin block B can be cut along the line corresponding to the line S 2… (Fig. 1, Fig. 3, Fig. 4). At this time, the transverse cutter wire S 2 which is a nylon thread stretches due to elasticity into a mountain shape, and as a result, the cutting progresses from the upper corners of both sides of the water-retaining foamed resin block B, so that the cutting resistance is small. Yes (Fig. 4). Ma In addition, the reaction force of the incision resistance applied to the transverse cutter wire S 2 is the force that acts as a force pulling the transverse force cutter wire S 2 upward in the vicinity of the retaining groove V 2. Opening sideways does not cause a problem that the stopper bracket 8 can be pulled out from the back surface of the reinforcing frame 6.

Since the transverse cutter line S2 is deformed into a chevron and the guide frame 5 has a vertical width, by pushing down the guide frame 5 to the end, the water retaining foam block B Can be separated easily. Also, even if an uncut portion is generated, the uncut portion may be broken, but by reversing the water-retaining foam resin block B, that is, by cutting the same position from the back side. Can be completely separated. Further, the guide frame 5 can be cut with the vertical direction reversed. Industrial applicability

As described above, the cutting device for water-retaining foamed resin block for ikebana of the present invention uses a thin wire material made of metal or resin that is difficult to be affected by frictional force and adhesive force of the object to be cut. Since it is a cutting tool, it has the property that it can be applied to sculpture clay, cheese, butter, tofu, and other gelatinous foods in the form of gelled food and intermediate materials. It can be used particularly suitably for the purpose of cutting the desired water-retaining foamed resin block for ikebana.
