Description

  The present invention relates to a foam clog made of foamed resin used by agricultural workers in the field.

  Traditionally, when a practitioner prunes or harvests a relatively tall plant, the high clogs have been used so that they can move sequentially while walking along the field fence and work continuously at high places. May be used. This type of high clogs includes simple high clogs, for example, a rugged plastic box with a string for tying them to a foot.

  However, in the case of the above-described simple high clogs, if the height required for working at a high place and the robustness that does not break even if a person is placed on it, the material of the box becomes heavy. Further, since the box is not intended to be worn on a person's foot, there is a problem that it is difficult to walk. Then, the high clogs for agricultural workers using the polystyrene foam as a material are known (for example, refer nonpatent literature 1). The high clog made of styrene foam is lightweight and has a certain elasticity, so that it is easy to walk on the field and can reduce the burden of farm workers on high places.

  A high clog according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 (a) and 1 (b), a high clog 1 is composed of an upper member 2 having a through hole 20 through which a umbilical cord H is inserted, and a box-shaped lower member connected to the upper member 2 and opened downward. 3. The upper member 2 serves as a platform on which the operator's feet are placed, and the bottom surface of the lower member 3 comes into contact with a ground contact surface such as a basket in the field.

  Each of the upper member 2 and the lower member 3 is a molded body of a foamed synthetic resin. For example, a foaming particle of a thermoplastic resin is filled in a mold, heated, foamed, and integrally molded. The thermoplastic resin is, for example, a styrene resin, or may be a composite resin in which another resin such as an olefin resin is mixed with the styrene resin.

  As shown in FIGS. 2A and 2B and FIGS. 3A to 3G, the upper member 2 includes an upper surface 21 serving as a top of the high clogs 1 and a lower surface 22 positioned on the opposite side of the upper surface 21. Have. The upper surface 21 and the lower surface 22 are substantially horizontal surfaces in use, and are connected by a front surface 23, both side surfaces 24 and 25, and a back surface 26, which are substantially vertical surfaces. The corners of the front surface 23, the side surfaces 24, 25, and the back surface 26 are all chamfered so as to be gently curved.

  The upper member 2 has a substantially rectangular shape when viewed from above, and is formed as a plate-like member having substantially the same thickness. In the present embodiment, the width on the front side 23 (toe side) is slightly smaller than the width on the back side 26 (back side) (see FIG. 3A). The thickness of the upper member 2 is preferably 20 to 40 mm, and more preferably 25 to 35 mm. When the thickness of the upper member 2 is 20 mm or more, the tied cords H can be stably held, and when the thickness is 40 mm or less, the strings H1 and H2 of the cords H can be easily inserted.

  The through-hole 20 for inserting the umbilical cord H (strings H1, H2) penetrates in a substantially vertical direction from the upper surface 21 toward the lower surface 22, and one front hole for allowing the front string H1 of the umbilical cord H to be inserted. 20a and two rear holes 20b for inserting the back cord H2 of the umbilical cord H. The front hole 20a is formed at a position closer to the middle of the toe side of the upper member 2, and the rear hole 20b is on the heel side than the center of the upper member 2 in a top view and connects the center of the upper surface 21 in the front-rear direction. It is formed symmetrically with the line (A-A line in FIG. 3B).

  Connection recesses 22 a to 22 c for connecting to the lower member 3 are formed on the lower surface 22. In the present embodiment, the connecting recess 22a closer to the center than the front hole 20a is formed so as to extend in the width direction of the high clogs, and the pair of connecting recesses 22b closer to the center is formed so as to extend in the length direction. The connecting recess 22c on the heel side of the rear hole 20b is formed to extend in the width direction.

  As shown in FIGS. 4 (a) and 4 (b) and FIGS. 5 (a) to 5 (f), the lower member 3 includes an upper bottom portion 4 connected to the upper member 2, and a ground plane formed integrally with the upper bottom portion 4. And a lower bottom portion 5 that abuts. The upper bottom portion 4 has a shape corresponding to the lower surface 22 of the upper member 2. The lower member 3 has legs (front legs 53, a pair of horizontal legs 54 and 55, and a rear legs 56) that extend from the four sides of the upper base 4.

  The upper bottom portion 4 has a substantially rectangular shape when viewed from above, and is formed as a plate-like member having substantially the same thickness. Like the upper member 2, the thickness of the upper bottom part 4 is preferably 20 to 40 mm, and more preferably 25 to 35 mm. The upper bottom portion 4 has an upper surface 41 connected to the lower surface 22 of the upper member 2 and a lower surface 42 located on the opposite side of the upper surface 41. On the upper surface 41, connection convex portions 41a to 41c for connecting to the connection concave portions 22a to 22c of the upper member 2 are formed. The upper surface 41 and the lower surface 42 are substantially flat surfaces inclined such that the toe side is slightly lower than the heel side, and these are connected by a front surface 43, both side surfaces 44 and 45, and a back surface 46, which are substantially vertical surfaces. . The corners of the front surface 43, both side surfaces 44 and 45, and the back surface 46 are all chamfered so as to be gently curved.

  The upper bottom part 4 has a through hole 40 formed in a region facing the through hole 20 (front hole 20a, rear hole 20b) of the upper member 2. The through-holes 40 penetrate substantially vertically from the upper surface 41 toward the lower surface 42. In the present embodiment, the through hole 40 has one round opening 40a corresponding to the front hole 20a of the upper member 2 and one horizontal elongated opening 40b corresponding to the two rear holes 20b. The round opening 40 a is formed larger than the front hole 20 a of the upper member 2. The laterally long opening 40b has an elliptical recess formed larger than the rear hole 20b of the upper member 2 and a flat recess connecting the elliptical recesses. The flat recess is longer than the elliptical recess in the length direction. It is formed to be wide.

  The lower bottom portion 5 includes a front leg portion 53, a pair of lateral leg portions 54 and 55, and a rear leg portion 56 that are respectively extended from four sides of the upper bottom portion 4 below a boundary portion 51 with the upper bottom portion 4. The front leg portion 53, the pair of horizontal leg portions 54 and 55, and the rear leg portion 56 are connected by adjacent vertical sides, and the bottom surface thereof becomes the bottom surface 52 of the lower member 3. The opening 52A of the lower member 3 is formed.

  The cross-sectional thickness of the front leg portion 53, the pair of horizontal leg portions 54 and 55, and the rear leg portion 56 is preferably 25 to 40 mm, and more preferably 30 to 35 mm. When the cross-sectional thickness is 25 mm or less, the structural strength against the load becomes insufficient, and when the area of the bottom surface 52 becomes too small, the grounding force becomes insufficient. On the other hand, when the cross-sectional thickness is 40 mm or more, the opening 52A becomes small, and there is a possibility that the binding of the umbilical cord described later becomes troublesome. By setting the cross-sectional thickness of each leg as described above, it is possible to ensure the structural strength and grounding force necessary for high clogs and to facilitate tying up the chords.

  The corners of the outer surfaces (front surface 53a, both side surfaces 54a, 55a, back surface 56a) of the front leg portion 53, the pair of horizontal leg portions 54, 55, and the rear leg portion 56 are the outer surfaces (43, 44, Similarly to the corners 45 and 46), each of the corners is chamfered so as to be a gently curved surface. The inner side surfaces (53b, 54b, 55b, 56b) of the front leg portion 53, the pair of horizontal leg portions 54, 55, and the rear leg portion 56 are substantially parallel to the outer side surfaces (53a, 54a, 55a, 56a), Both of them are inclined outward so that the opening 52A becomes large. The oblong opening 40b corresponding to the rear hole 20b is formed so as to partially cut out the inner side surfaces 54b and 55b (see FIG. 5B).

  Each outer side surface (the front surface 53a, both side surfaces 54a, 55a, and the back surface 56a) of the lower bottom portion 5 is formed so as to spread outward as it goes downward from above. Therefore, the size of the outer edge of the bottom surface 52 of the lower bottom part 5 is larger than the size of the outer edge of the upper surface 41 of the upper bottom part 4 (the upper surface 21 of the upper member 2). That is, since the bottom surface 52 has a large area in contact with the ground contact surface, even an unstable scaffold such as a field fence can be stably grounded.

  Further, the lower bottom portion 5 of the present embodiment has a trapezoidal shape in which the width in the lower part is wider than the upper part in the front view (or back view (see FIG. 5D)) shape. That is, both side surfaces 54a and 55a are inclined more greatly than the front surface 53a and the back surface 56a, and the width of the bottom surface 52 is widened. Agricultural workers often walk the crab sideways (crabs) while facing the crops. In the present embodiment, as described above, since the width of the bottom surface 52 is widened, the operator can stably ground and walk even when walking sideways. Further, the toe side of the bottom surface 52 is an inclined surface 52B cut upward, which prevents the operator from tripping and improves the ease of walking.

  The upper member 2 and the lower member 3 configured as described above are formed on the lower surface 22 of the upper member 2 as shown in FIGS. 6 (a) and 6 (b) and FIGS. 7 (a) to 7 (f). 22a-22c and the connection convex parts 41a-41c formed in the upper surface 41 of the lower member 3 (upper bottom part 4) are fitted, and also the lower surface 22 of the upper member 2 and the upper surface 41 of the lower member 3 are By being bonded, it is firmly fixed. The lower member 3 may be formed with a connecting concave portion, and the upper member 2 may be formed with a connecting convex portion.

  As shown in FIGS. 6 (a) and 6 (b), the outer surface (front surface 43, both side surfaces 44, 45, back surface 46) of the upper base 4 is formed as a substantially vertical surface. Are connected smoothly to the vertical side surfaces of the upper member 2 (the front surface 23, the side surfaces 24, 25, and the back surface 26). Further, when looking through the opening 52A of the lower member 3 from the bottom surface side of the high clog 1, the through hole 20 (front hole 20a, rear hole 20b) of the upper member 2 extends from the through port 40 (round port 40a, horizontally long port 40b). It is exposed on the lower bottom 5 side.

  In order to attach the umbilical cord H to the high clogs 1, first, the front string H1 of the umbilical cord H is inserted into the front hole 20a, and the metal washer S1 is attached to the front hole 20a from the lower surface 22 side of the upper member 2. The front string H1 is attached to the high clogs 1. Further, the two end portions of the rear cord H2 of the umbilical cord H are inserted into the rear hole 20b, and they are bound on the lower surface 22 side of the upper member 2. For binding the rear string H2, the strings themselves may be bound to each other, or as shown in the figure, they may be bound by a predetermined binding tool S2. When inserting the front string H1 or the rear string H2 through the front hole 20a or the rear hole 20b, it is only necessary to insert the front string H1 or the rear string H2 by the thickness of the upper member 2, and it is not necessary to insert the thickness of the lower member 3. , Can bind the umbilical cord easily.

  Thus, according to the high clogs 1 of the present embodiment, when the front string H1 or the rear string H2 is inserted through the front hole 20a or the rear hole 20b, it is only necessary to insert it by the thickness of the upper member 2. Further, since it is not necessary to pass through the thickness of the lower member 3, it is possible to bind the cords easily. In addition, when wearing the chord H at the time of manufacturing the high clog 1, it is only necessary to put the chord H on the upper member 2 before connecting the upper member 2 and the lower member 3. The (lower member 3) does not get in the way, and the umbilical cord H can be bound more easily.

  Further, when the umbilical cord H is attached or replaced after the upper member 2 and the lower member 3 are connected, the through hole 20 (the front hole 20a and the rear hole 20b) of the upper member 2 is also connected to the lower member 3 ( Since it is exposed from the opening 52A on the lower bottom part 5 side through the through hole 40 (round opening 40a, horizontally long opening 40b) in the upper bottom part 4), the operator can put his hand into the opening 52A, and the chord H is easy. Can be tied together. Further, the upper base 4 of the lower member 3 is not opened except for the through hole 40, and is overlapped with the upper member 2. Therefore, the weight of the worker wearing the high clogs 1 is set to the thickness of the upper member 2 and the lower part. It can be received by both the thickness of the upper bottom portion 4 of the member 3, and the structural strength required as the high clogs 1 can be obtained. And while having sufficient intensity | strength, since the upper member 2 and the lower member 3 which comprise the high clogs 1 are all made from a foamed resin, it is lightweight and easy to walk, and can reduce the burden of the high work of an agricultural worker. it can.

  Further, the front string H1 and the rear string H2 inserted into the lower member 3 side of the cord H are accommodated in the spaces formed with the round mouth 40a and the laterally long mouth 40b in the upper bottom part 4, respectively. At this time, since the front string H1 and the rear string H2 are held at a high position with respect to the bottom surface 52 of the lower member 3, the front string H1 and the rear string H2 taken out to the bottom surface side of the high clogs 1 are placed on the ground surface. It becomes difficult to touch, and it is possible to suppress getting wet or dirty with accumulated water or mud on the ground surface.

  Moreover, since the high clogs 1 can be divided into the upper member 2 and the lower member 3, for example, the lower member 3 is manufactured with a plurality of patterns having different heights, while the upper member 2 has any height. But you can share it.

  Note that the present invention is not limited to the above-described embodiment as long as the configuration includes the upper member 2 having the through hole 20 through which the umbilical cord H is inserted and the lower member 3 connected to the upper member 2. Can be modified. For example, in the above embodiment, the configuration including one front hole 20a and two rear holes 20b as the through hole 20 through which the umbilical cord H is inserted is shown. However, the number and arrangement of the through holes are the same as the above-described configuration example. It is not limited and can be changed as appropriate.
