  However, in order to form the concave portion 204 and the step 209 on the inner side surface 208 of the side frame 207 of the conventional pedestal cover 201, a plurality of slide cores are used at the time of mold forming, so that the molding cost increases. Moreover, although the recessed part 204 and the level | step difference 209 can also be formed by performing a cutting process after metal mold | die shaping | molding, since the cutting process was required, there also existed a problem that a manufacturing cost also raised.

  Accordingly, an object of the present invention is to provide a pedestal cover, a pedestal, and a pedestal structure that can suppress an increase in manufacturing cost without using a plurality of slide cores when molding a mold.

  That is, the present invention solves the above-described conventional problems, and is a pedestal cover having a frame structure with a U-shaped cross-section that fits on a pedestal and substantially covers the front and peripheral surfaces of the pedestal. The inner side surface of the side frame on the upper side of the pedestal cover is formed in a tapered shape so that the opening becomes narrower toward the opening side, and the inner side surface of the side frame on the lower side of the pedestal cover is opened toward the opening side. The present invention provides a pedestal cover that is formed into a wide tapered shape, and is formed with a notch-shaped recess that engages with an engaging protrusion of the pedestal on the side frame on the lower side of the pedestal cover.

  Further, the present invention is manufactured from a fixed mold plate, a movable mold plate facing the fixed mold plate through a gap, and a molding die including a slide core, and the fixed mold plate is inclined. The movable plate has a top portion and a convex portion having a horizontal portion and a vertical side portion, and the movable plate extends at a right angle from the inclined bottom surface and the inclined bottom surface. The pedestal cover having a concave portion formed of a first inclined side surface, the slide core having a second inclined side surface parallel to the first inclined side surface and a protrusion formed at a lower portion of the second inclined side surface Is to provide.

  Further, the present invention is a pedestal to which the pedestal cover is attached, the pedestal main body accommodated in a frame body of the pedestal cover, and a concave portion of the pedestal cover protruding downward from a lower end of the pedestal main body. There is provided a pedestal including a mating engagement protrusion and a protrusion formed on the side surface on the upper side of the pedestal main body portion and in the vicinity of the front side of the pedestal cover.

  Further, the present invention provides the pedestal cover, a pedestal main body portion accommodated in a frame body of the pedestal cover, and an engagement protrusion that engages with a concave portion of the pedestal cover protruding downward from the lower portion of the pedestal main body portion. And a pedestal structure comprising a pedestal provided on a side surface on the upper side of the pedestal main body and a protrusion formed in the vicinity of the front side of the pedestal cover.

  In the pedestal structure of the present invention, since the protruding portion of the pedestal enters the inner surface of the back slope of the side frame (upper side) of the pedestal cover, the upper side is prevented from coming off. Moreover, since the recessed part of a base cover and the engagement protrusion of a base engage, it prevents that the said lower part side remove | deviates. Moreover, it is easy to fit the base cover to the base. In addition, the special shape of the inside surface of the frame of the pedestal cover can be achieved by a simple combination of a fixed mold plate having a convex portion with a specific shape and a movable mold plate having a concave portion, thus increasing the manufacturing cost. Suppress.

  A pedestal according to the first embodiment of the present invention will be described with reference to FIGS. 1 is a front view of the pedestal cover of this example, FIG. 2 is a rear view of FIG. 1, FIG. 3A is a view taken along the line AA in FIG. 2, and FIG. FIG. 4A is a diagram viewed along line B, FIG. 4A is a diagram viewed along line CC in FIG. 2, and FIG. 4B is a bottom view of FIG. The pedestal cover 10 is made of metal or plastic, has a U-shaped cross-section that fits on the pedestal and substantially covers the front surface and the peripheral surface of the pedestal, and has a handle attachment hole 2 through which the handle shaft passes in the center. The frame structure 1 has a rectangular shape when viewed from the front. That is, the pedestal cover 10 includes a top plate 11, upper side frames 12 extending rearward from the top plate 11, left and right side frames 14, and lower side frames 13. In the present invention, in the state of use of the pedestal structure, since the notch-shaped recess is normally located below, the side frame having the notch-shaped recess is defined as the lower side (lower part), and the opposite side is the upper side (lower side). Top).

  The pedestal cover 10 is formed in a tapered shape in which the inner side surface 121 of the side frame 12 (upper side) of the pedestal cover 10 becomes narrower toward the opening side X (see FIG. 3A), and the side of the pedestal cover 10 The inner surface 131 of the frame 13 (lower side) is formed in a tapered shape in which the opening becomes wider toward the opening side X (see FIG. 3A), and the pedestal is engaged with the side frame 13 on the lower side of the pedestal cover 10. A notch-like recess 3 that engages with the mating protrusion is formed. By making the side frame 12 of the pedestal cover 10 into a tapered shape as described above, the protruding portion of the pedestal enters the inner space, and does not come off from the pedestal cover 10 by vibrations or the like. On the other hand, the side frame 13 of the pedestal cover 10 has a tapered shape as described above because the movable template needs to be removed during the molding of the mold. Since the 10 recesses 3 and the engagement protrusion 24 of the base 20 can be strongly fitted, the generation of the gap 29 associated with the tip shape does not affect the fitted state (see FIG. 11).

  In addition, the left and right side frames 14 and 14 extend vertically from the top plate 11 (see FIG. 4C). The inside of the frame of the pedestal cover 10 is a space in which the pedestal main body is accommodated. In the pedestal cover 10, the opening narrows toward the opening side X of the inner side surface 131 of the side frame 12 facing the side frame 13 in which the notch-shaped recess 3 is formed, that is, the opening side X of the side frame 12 is By making the taper shape inclined inward, the inner surface 121 of the side frame 12 becomes a regulating surface from which the pedestal cover 10 is removed from the pedestal, and the projecting portion of the pedestal strongly fits into the notch-shaped concave portion 3. The pedestal cover 10 is fixed at the end of the pedestal, and the pedestal cover 10 is prevented from falling off from the pedestal.

  The notch-shaped recess 3 is a portion into which the protrusion of the pedestal fits. The shape of the notch is not particularly limited, but in this example, the opening is wide, narrows as it goes in, and widens as it goes further. This is a so-called constricted structure. As a result, when the protrusion of the base is inserted into the recess 3 and further strongly pushed by hand, it deforms to overcome the constricted portion and fits strongly into the recess 3, and then does not easily come off. Can be taken.

  Next, the pedestal of this example will be described with reference to FIGS. 5 is a perspective view of the pedestal of this example, FIG. 6 is a front view of the pedestal of this example, FIG. 7 is a rear view of the pedestal of FIG. 6, FIG. 8 is a bottom view of the pedestal of FIG. It is a top view of a base. The pedestal 20 is made of plastic and has a shape that fits into the pedestal cover 10 described above. That is, the pedestal 20 includes a pedestal main body 21 having plate-like protrusions 22 protruding obliquely outward at four corners, and an engagement protrusion 24 that engages with a recess of the pedestal cover protruding downward from the lower end of the pedestal main body 21. The protrusion formed on the upper side surface 26 of the pedestal main body 21 and in the vicinity of the front side of the pedestal cover, that is, on the back side in the thickness direction of the upper side surface 26 in FIG. 5 (front side in FIG. 5). 23 (see FIG. 9). In the pedestal 20 of the present invention, the plate-like protrusions 22 at the four corners are optional components.

  The shape of the engagement protrusion 24 is not particularly limited, but is U-shaped in this example (see FIG. 8). By making the shape of the engagement protrusion 24 U-shaped, it is easy to elastically deform when sandwiched from both sides, easily fit into the recess of the pedestal cover 10, and once fitted, it is difficult to come off. can get.

  The protrusion 23 enters the space 301 on the back side (bottom) of the inner side surface 121 of the side frame 12 (upper side) of the pedestal cover 10, and prevents the pedestal cover 10 from being detached from the pedestal 20. It has a height that fits (see FIG. 13). The length (l) of the protrusion 23 may be the same as the length (L) of the upper side surface 26 of the pedestal main body 21 at the maximum, Even if an external force acts in the direction of detachment, the length (L) of the upper side surface 26 is set to about 1/5 to 1/2, and an appropriate frictional force with the inner side surface 121 of the upper side frame 12. Is preferable in that it acts and becomes difficult to come off. The protrusion 23 may be one having dots in the longitudinal direction in addition to the one having the above-mentioned longitudinal portion. The protrusion 23 may be a single point-like object, but the pedestal cover 10 is easily detached from the pedestal 20.

  A hole 255 at the center of the pedestal main body 21 is a handle attachment hole through which the handle shaft passes. The base 20 is formed with a pair of screw insertion holes (or headed boss mounting holes) 27. The through holes 212 formed at the four corners of the pedestal main body 21 are not only thinned but also have a dimension adjusting function. That is, when the pedestal cover 10 is attached to the pedestal 20, even if the dimension formed by the plate-like protrusions 22 at the four corners is slightly larger than the inner dimension of the pedestal cover 10, Since the protrusions 22 are thin, they can be deformed by elasticity, and the pedestal cover 10 can be attached to the pedestal 20. The cylindrical step 213 at the center of the pedestal main body 21 is a portion into which the back surface of the thumb turn knob is fitted. Further, the through hole 214 formed on the circumference passing through the screw insertion hole 27 is thinned. Further, the notch portion denoted by reference numeral 215 is a portion into which the protrusion on the back surface portion of the thumb turn knob is fitted. Further, the four resilient projecting pieces 216 formed around the handle mounting hole 255 of the pedestal main body 21 are members that fit on the thumb-turn shaft. In the present invention, the through-holes 212 formed in the four corners, the cylindrical step 213, the through-hole 214 formed in the cylindrical step, the notch 215, and the projecting piece 216 depend on the type of thumb turn and lever handle. It is an arbitrary component appropriately determined depending on the shape and the like.

  Next, the pedestal structure of the present invention will be described with reference to FIGS. 10 is a front view of the pedestal structure of this example, FIG. 11 is a rear view of the pedestal structure of FIG. 10, FIG. 12 is a bottom view of the pedestal structure of FIG. 10, and FIG. FIG. 14 is a longitudinal sectional view of a pedestal structure according to another embodiment.

  The pedestal structure 30 of this example is an assembly of the pedestal cover 10 and the pedestal 20. That is, in order to assemble the pedestal cover 10 to the pedestal 20, the protrusion 23 of the side surface 26 on the upper side of the pedestal main body 21 is placed in the space 301 on the back side (bottom) of the inner side surface 121 of the side frame 12 of the pedestal cover 10. Only the upper side is fitted so as to enter, that is, the base 20 is fitted to the pedestal cover 10 so as to be oblique, or the pedestal cover 10 is fitted to the pedestal 20 so as to be oblique, The lower side of the pedestal cover 10 is strongly pushed into the engagement protrusion 24 of the pedestal main body 21 with a finger. Thereby, the recessed part 3 of the base cover 10 and the engagement protrusion 24 of the base 20 are strongly fitted to the base cover 10 and the base 20 on the lower side, and the protrusion 23 of the base main body 21 is the base on the upper side. The movement in the direction of disengagement is restricted by the side frame 12 on the upper side of the cover 10, and both of them are not easily detached by vibration during use. Since the thickness of the pedestal main body 21 and the inner height of the frame of the pedestal cover 10 are substantially the same, the pedestal main body 21 is not visible in a side view when incorporated in the pedestal cover 10.

  In addition, the protrusion part 23 is not limited to the said form, For example, as shown in FIG. 14, the side surface 26b of the upper side of the base main-body part 21 is a taper-shaped thing which expands to the back side (right side in FIG. 14). It may be. Even in this pedestal structure 30 b, the upper side of the pedestal cover 10 and the pedestal 20 moves in a direction in which the tapered protrusion 27 b of the pedestal main body 21 is detached by the side frame 12 on the upper side of the pedestal cover 10. As in the case of the pedestal structure 30, both are not easily detached by vibration during use.

  Next, a method for manufacturing the pedestal cover 10 will be described with reference to FIGS. 15 is an exploded view of the plastic injection mold after molding, FIG. 16 is a cross-sectional view of the assembly of the plastic injection mold, and FIG. 17 is a vertical cross-sectional view of FIG. The pedestal cover 10 is manufactured from a fixed mold plate 41, a plastic mold 40 having a movable mold plate 42 and a slide core 44 that are opposed to the fixed mold plate 41 through a gap 45. In the present invention, examples of the molding die include a mold for casting a molten metal in addition to the plastic injection molding die.

And a first inclined surface 413 located between the second horizontal portion 412 and a convex portion 47 formed on the first inclined surface 413. The convex portion 47 creates an internal space of the frame body of the base cover 10, and has a sloped top portion 45 that is horizontal to the first inclined surface 413 and a first horizontal portion 411 (second horizontal portion of the fixed template 41). Part 412) and a vertical side 46. In addition, a circular protrusion 414 that forms a through hole through which the handle shaft passes is formed at the center of the top portion 45.

  The movable mold plate 42 is installed on the upper surface of the fixed mold plate 41. The movable mold plate 42 is provided on the third horizontal portion 421 that contacts the first horizontal portion 411 of the fixed mold plate 41 and the first inclined surface 413 of the fixed mold plate 41. It has the 2nd inclined surface 422 to contact | abut, the inclined side surface 423 to contact | abut the inclined surface 442 of a slide core, and the recessed part 49 formed in the 2nd inclined surface 422 in the hollow shape. The concave portion 49 includes an inclined bottom surface 48 having the same inclination as the inclined top portion 45 of the fixed mold 41 and a first inclined side surface 481 extending perpendicularly from the inclined bottom surface 48.

  The slide core 44 includes a fourth horizontal portion 441 that contacts the second horizontal portion 412 of the fixed mold plate 41, a third inclined side surface 442 that contacts the inclined side surface 423 of the movable mold plate 42, and a lower portion of the third inclined side surface 442. And a protrusion 443 that forms a notch-shaped recess.

  When the plastic injection mold is assembled, a gap Y in the shape of a pedestal cover is formed (FIG. 16). Further, after molding, the movable mold plate 42 is moved upward, and the slide core 44 is moved to the opposite side (left side in FIG. 16) from the protrusion 443, so that the mold is removed and the base cover is removed. Is obtained. From the inclined shape of the fixed mold 41 and the movable mold 42, the inner side surface 121 of the upper side frame 12 is formed in a tapered shape with the opening narrowing toward the opening side, and the lower side frame 13 of the base cover 10 is formed. The inner side surface 131 is formed in a tapered shape in which the opening becomes wider toward the opening side.

  Since the pedestal cover 10 of the present invention can be manufactured with three main mold plates, that is, a fixed mold plate 41, a movable mold plate 42, and a slide core 44, a plurality of slide cores that have been conventionally used can be used, and cutting can be performed. Since a process is also unnecessary, an increase in manufacturing cost can be suppressed.
