However, in the inner side surface 208 of the side frame 207 of the conventional pedestal cover 201, since the concave portion 204 or the step 209 is formed, it is necessary to use a plurality of slide cores or slide cores during molding of the metal mold. Therefore, the cost of forming will increase. Further, after the metal mold is formed, the concave portion 204 or the step 209 can be formed by performing the cutting step. However, since the cutting step is necessary, there is a problem that the manufacturing cost is increased.

Accordingly, it is an object of the present invention to provide a pedestal cover, a pedestal and a pedestal structure which can reduce the manufacturing cost without using a plurality of sliding dies in the molding of a metal mold.

That is, the present invention has been made to solve the above problems, and provides a front surface and a peripheral surface which are substantially fitted to a pedestal and cover the pedestal. a pedestal cover of a frame structure having a cross-section, the inner side surface of the side frame on the upper side of the pedestal cover faces the opening side, and the opening thereof is formed into a narrow push-out shape, and the inner side surface of the side frame on the lower side of the pedestal cover The opening is formed toward the opening side, and the opening is formed in a wide push-out shape, and the side frame on the lower side of the pedestal cover forms a notch-like recess that is engaged with the tying projection of the pedestal, and the pedestal cover thus formed.

Moreover, the present invention provides a movable die plate and a sliding die which have a die-plate and a fixed position with a gap in the opposite position, and are formed by using a metal mold for molding. The template has: a sloping top portion and a convex portion having a vertical side portion with a horizontal portion of the fixed template; the movable template having: an inclined bottom surface inclined at the same angle as the inclined top portion and a second angle extending from the inclined bottom surface a concave portion formed by the inclined side surface; the sliding mold 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; the pedestal cover thus formed .

Moreover, the present invention provides a pedestal mountable with a pedestal cover having a pedestal body portion housed in a frame body of the pedestal cover; protruding downward from a lower end of the pedestal main body portion and engaging with a recessed portion of the pedestal cover And a pedestal formed by the protruding portion formed on the side surface on the upper side of the pedestal main body portion and formed in the vicinity of the front side of the pedestal cover.

Moreover, the present invention provides a pedestal cover, a pedestal main body housed in a casing of the pedestal cover, and a tying projection that protrudes downward from a lower end of the pedestal main body and is coupled to a recess of the pedestal cover. And a side surface on the upper side of the pedestal body portion and a protruding portion formed in the vicinity of the front side of the pedestal cover; such a pedestal constitutes the pedestal structure.

In the pedestal structure of the present invention, since the protruding portion of the pedestal enters the inner side surface of the side frame (upper side) of the pedestal cover, the upper side can be prevented from coming off. Further, since the recessed portion of the pedestal cover is attached to the engaging projection of the pedestal, it is prevented from falling off at the lower side. Moreover, the fitting of the pedestal cover to the pedestal can also be easily carried out. Further, the special shape of the inner side surface of the casing of the pedestal cover can be achieved by simply combining a fixed stencil having a convex portion having a specific shape and a movable stencil having a concave portion, thereby suppressing an increase in manufacturing cost.

A pedestal according to a first embodiment of the present invention will be described with reference to Figs. 1 to 4 . 1 is a front view of the pedestal cover of the present embodiment, FIG. 2 is a rear view of FIG. 1, FIG. 3(A) is a view taken along line A-A of FIG. 2, and (B) is taken along line B-B of FIG. 4(A) is a view taken along line C-C of FIG. 2, and (B) is a bottom view of FIG. The pedestal cover 10 is made of metal or plastic, and is fitted on the pedestal, substantially covering the front and the periphery of the pedestal. The word-shaped cross section has a handle mounting hole 2 through which the handle shaft can be inserted in the center portion, and a frame structure 1 having a rectangular shape in front view. That is, the pedestal cover 10 has a top plate 11, a side frame 12 extending from the top plate 11 toward the rear side, a side frame 12 on the left and right sides, and a wall-like body at the four corners of the lower side side frame 13; . Further, in the use state of the pedestal structure of the present invention, since the notched recess is generally located below, the side frame having the notched recess is regarded as the lower side (lower portion), and the opposite side is regarded as the upper side ( Upper).

In the pedestal cover 10, the inner side surface 121 of the side frame 12 (upper side) of the pedestal cover 10 is formed so as to be narrowed toward the opening side X (see FIG. 3(A)), and the pedestal cover 10 is The inner side surface 131 of the side frame 13 (lower side) faces the opening side X such that the opening thereof is formed in a wide push-out shape (see FIG. 3(A)), and the side frame 13 on the lower side of the pedestal cover 10 is formed to be coupled to The notched recess 3 of the pedestal of the pedestal is configured as described above. When the side frame 12 of the pedestal cover 10 is formed in the above-described push-out shape, the protruding portion of the pedestal can enter the space portion inside, and does not fall off from the pedestal cover 10 when vibrating or the like. On the other hand, the side frame 13 of the pedestal cover 10 is formed in the above-described front end push-out shape because the movable die plate must be detached during the molding of the metal mold, but the recessed portion 3 and the pedestal of the pedestal cover 10 are formed in the side frame 13. The engaging projection 24 of 20 can be strongly fitted, and therefore, the gap 29 which occurs due to the shape of the front end does not affect the fitting state (refer to Fig. 11).

Further, the side frames 14 and 14 on the left and right sides extend vertically from the top plate 11 (see FIG. 4(A)). The frame inside the pedestal cover 10 is a space for accommodating the main body of the pedestal. In the pedestal cover 10, the inner side surface 131 of the side frame 12 facing the side frame 13 in which the notched recess 3 is formed faces the opening side X so that the opening becomes narrow, that is, the opening side X of the side frame 12 is When the inner side is inclined to form a push-out shape, the inner side surface 121 of the side frame 12 becomes a restriction surface from which the pedestal cover 10 is detached from the pedestal, and since the protruding portion of the pedestal is strongly fitted into the notch-shaped recessed portion 3, the upper and lower sides are The end portion can fix the pedestal cover 10, so that it can prevent the pedestal cover 10 from coming off the pedestal.

The notched recess 3 is a portion in which the protruding portion of the pedestal is embedded, and its shape is not particularly limited. In this example, the opening portion is wide, and gradually becomes narrow toward the inside, and then gradually becomes wider toward the inside. "Middle thinning" structure. As a result, the protruding portion of the pedestal is inserted into the recessed portion 3, and when the hand is pressed more strongly by the hand, the deformation is made to extend beyond the intermediate tapered portion to be strongly fitted to the concave portion 3, and thereafter, the fitting is not easily detached. form.

Next, the pedestal of this example will be described with reference to Figs. 5 to 9 . Figure 5 is a perspective view of the pedestal of the present example, Figure 6 is a front view of the pedestal of this example, Figure 7 is a rear view of the pedestal of Figure 6, Figure 8 is a bottom view of the pedestal of Figure 6, and Figure 9 is a bottom view of Figure 6. Floor plan of the pedestal. The pedestal 20 is made of plastic and can be embedded in the shape of the pedestal cover 10. That is, the pedestal 20 has a pedestal main body portion 21 having a plate-like projection 22 that protrudes to the outer side at an oblique angle at four corners, and a tying projection that is engaged with a concave portion of the pedestal cover that protrudes downward from the lower end of the pedestal main body portion 21. 24; and the side surface 26 on the upper side of the pedestal main body portion 21 in the vicinity of the front side of the pedestal cover, that is, the inner side in the thickness direction of the side surface 26 formed on the upper side in FIG. 5 (the front side in FIG. 5) The protruding portion 23 (see Fig. 9). Further, in the pedestal 20 of the present invention, the plate-like projections 22 at the four corners are arbitrary constituent elements.

The shape of the tying protrusion 24 is not particularly limited, in this example Word shape (refer to Figure 8). It is formed by the shape of the tying protrusion 24 In the case of the word shape, when it is held from both sides, it can be easily elastically deformed and easily inserted into the concave portion of the pedestal cover 10, and once it is fitted, it becomes a fitting state in which it is difficult to fall off.

The protruding portion 23 is a space 301 that enters the inner side (bottom portion) of the inner side surface 121 of the side frame 12 (upper side) of the pedestal cover 10, and has a height that can accommodate the space 301 in order to prevent the pedestal cover 10 from coming off the pedestal 20. Refer to Figure 13). Further, the length (1) of the protruding portion 23 may be the same as the length (L) of the side surface 26 on the upper side of the pedestal main body portion 21, but the side surface 26 constituting the upper portion side of the pedestal main body portion 21 is provided. When the length (L) is about 1/5 to 1/2, even if there is an external force in the falling direction, the inner side surface 121 of the side frame 12 on the upper side has an appropriate frictional force and is difficult to fall off. . In addition to the above-described long side portion, the protruding portion 23 may be scattered in the longitudinal direction. Further, the protruding portion 23 may have only one dot, but the pedestal cover 10 is easily detached from the pedestal 20.

The center hole 255 of the pedestal body portion 21 is a hole for attaching the handle of the handle shaft. Further, a pair of small screw insertion holes (or bobbin mounting holes) 27 are formed in the pedestal 20. The through hole 212, which is formed at the four corners of the base portion 21 of the pedestal, has a function of being adjustable in size while being lightweight. That is, when the pedestal cover 10 is attached to the pedestal 20, even if the size of the plate-like projections 22 of the four corners is slightly larger than the inner dimension of the pedestal cover 10, the wall between the through-holes 212 and the plate-like projections 22 is It is very thin and can be deformed by elasticity, so that the pedestal cover 10 can be mounted on the pedestal 20. Further, the cylindrical height difference 213 at the center of the pedestal main body portion 21 is a portion in which the inner portion of the knob of the thumb turn is fitted. Further, the through hole 214 formed in the circumference penetrating through the small screw insertion hole 27 can be made lightweight. Further, the notch portion of the symbol 215 is a portion in which the projection of the inner portion of the knob of the spin lock is fitted. Further, the four elastic tabs 216 formed around the handle mounting hole 255 of the pedestal main body portion 21 can be fitted into the member of the shaft of the thumb lock. Further, in the present invention, the through hole 212 provided at the four corners, the cylindrical step 213, the through hole 214 formed in the cylindrical step portion, the notch portion 215, and the tab 216 are interlocked. Any of the constituent elements can be appropriately determined depending on the type or the shape of the handle bar.

Figure 10 is a front view of the pedestal structure of the present embodiment, Figure 11 is a rear view of the pedestal structure of Figure 10, Figure 12 is a bottom view of the pedestal structure of Figure 10, and Figure 13 is along the line D-D of Figure 10. FIG. 14 is a longitudinal cross-sectional view of a pedestal structure of another form.

The pedestal structure 30 of this example is assembled with the pedestal cover 10 and the pedestal 20. In other words, when the pedestal cover 10 is assembled to the pedestal 20, the protruding portion 23 of the side surface 26 on the upper side of the pedestal main body portion 21 is inserted into the space 301 of the inner side (bottom) of the inner side surface 121 of the side frame 12 of the pedestal cover 10, and only The upper side is embedded, that is, the pedestal 20 is embedded obliquely with respect to the pedestal cover 10, or the pedestal cover 10 is obliquely fitted with respect to the pedestal 20, and in this state, the lower side of the pedestal cover 10 is relatively pointed with respect to the pedestal with a finger. The engaging projection 24 of the main body portion 21 is pushed in strongly. Thereby, the pedestal cover 10 and the pedestal 20, on the lower side, the recessed portion 3 of the pedestal cover 10 and the tying projection 24 of the pedestal 20 are strongly fitted, and on the upper side, the protruding portion 23 of the pedestal main body portion 21 is covered by the pedestal cover. The side frame 12 on the upper side of the 10 is restricted from moving in the direction in which it is detached, and both of them are less likely to fall off during vibration or the like in use. Further, since the thickness of the pedestal main body portion 21 and the inner height of the casing of the pedestal cover 10 are substantially the same, when the pedestal main body portion 21 is assembled to the pedestal cover 10, it is not visible from the side view.

Further, the protruding portion 23 is not limited to the above-described embodiment. For example, as shown in FIG. 14, the side surface 26b on the upper side of the pedestal main body portion 21 may be formed in a push-up shape in which the inner side (the right side in FIG. 14) is enlarged. Even in the pedestal structure 30b, the pedestal cover 10 and the upper side of the pedestal 20 are restricted from the side frame 12 on the upper side of the pedestal cover 10 by the push-out protruding portion 27b of the pedestal main body portion 21, and are restricted toward the detaching direction. Since it moves, similarly to the pedestal structure 30, both of them are not easily detached by vibration or the like during use.

Next, a method of manufacturing the pedestal cover 10 will be described with reference to Figs. 15 to 17 . Fig. 15 is an exploded perspective view showing a metal mold for molding a plastic injection molding, Fig. 16 is a cross-sectional view showing an assembly of a metal mold for plastic injection molding, and Fig. 17 is a longitudinal sectional view of Fig. 15. The pedestal cover 10 is provided with: a fixed die plate 41; and a movable die plate 42 and a sliding die 44 which are positioned opposite to each other via the gap 45 by the fixed die plate 41; and such a plastic injection molding die 40. Further, in the present invention, in addition to the above-described plastic injection molding die, the molding die may be a casting mold of a liquid metal.

The fixed template 41 is disposed on a horizontal base (not shown), and is composed of: a first horizontal portion 411 on the upper surface; a second horizontal portion 412 that is lower than the first horizontal portion 411; and is located in the first horizontal portion 411 and 2, the first inclined surface 413 between the horizontal portions 412; and the convex portion 47 formed on the first inclined surface 413; The convex portion 47 is an internal space of the frame body of the pedestal cover 10, and has a top portion 45 that is horizontally inclined with respect to the first inclined surface 413, and a first horizontal portion 411 (second horizontal portion 412) that fixes the template 41. Vertical side 46. Further, a center portion of the top portion 45 is formed with a through hole through which the handle shaft can be inserted, and a circular projecting portion 414 is formed.

The movable die plate 42 is disposed on the upper surface of the fixed die plate 41, and has a third horizontal portion 421 that abuts against the first horizontal portion 411 of the fixed die plate 41, and a second slope that abuts against the first inclined surface 413 of the fixed die plate 41. The surface 422 is abutted against the inclined side surface 423 of the inclined surface 442 of the sliding mold, and is formed in the mortise-shaped concave portion 49 of the second inclined surface 422. The concave portion 49 is composed of an inclined bottom surface 48 that is inclined at the same angle as the inclined top portion 45 of the fixed die plate 41, and a first inclined side surface 481 that extends at right angles from the inclined bottom surface 48.

The sliding mold core 44 has a fourth horizontal portion 441 that abuts against the second horizontal portion 412 of the fixed die plate 41, a third inclined side surface 442 that abuts against the inclined side surface 423 of the movable die plate 42, and a third inclined side surface that is formed on the third inclined side surface 423 At a lower portion of 442, a projection 443 having a notched recess is formed.

When the metal mold for plastic injection molding is assembled, a gap Y of the shape of the pedestal cover is formed (Fig. 16). Further, when the movable die plate 42 is moved upward after the molding, the slide die 44 is moved toward the opposite side (the left side in FIG. 16) of the projection 443, and the mold is opened to obtain the pedestal cover. Due to the inclined shape of the fixed die plate 41 and the movable die plate 42, the inner side surface 121 of the side frame 12 on the upper side can be formed in a narrow push-out shape toward the opening side, and the side frame 13 on the lower side of the pedestal cover 10 can be formed. The inner side surface 131 faces the opening side such that the opening is formed in a wide push-out shape.

Since the pedestal cover 10 of the present invention can be manufactured by three main templates, such as a fixed template 41, a movable die plate 42, and a sliding die 44, it is not necessary to use a plurality of sliding dies as in the past, and no cutting step is required. Therefore, the manufacturing cost can be reduced.

The pedestal 20 of the present invention can be manufactured using a well-known metal mold.

The pedestal cover 10 and the pedestal 20 of the present invention are not limited to the above-described embodiments, and may be, for example, a circular shape in a front view. A circular pedestal cover will be described below with reference to Figs. 18 to 21 . Fig. 18 is a front view of the pedestal cover of the present embodiment, Fig. 19 is a rear view of Fig. 18, Fig. 20 is a view taken along line E-E of Fig. 19, and Fig. 21 is a view taken along line F-F of Fig. 19. In the pedestal cover 10a, the same components as those of the pedestal cover 10 are denoted by the same reference numerals, and the description thereof will be omitted. Here, only the differences will be mainly described. The pedestal cover 10a is made of metal or plastic, and is fitted on the pedestal and substantially covers the front and the circumferential surface of the pedestal. The figure-shaped cross section has a frame structure in which a handle attachment hole 2a that can be inserted into the handle shaft is inserted in the center portion and has a circular shape from the front. That is, the pedestal cover 10a is composed of a disk-shaped top plate 11a and a side frame 14a of a belt-shaped cylindrical body extending perpendicularly from the end portion of the top plate 11a toward the rear.

The pedestal cover 10a is formed such that the inner side surface 121a of the side frame 12a on the upper side of the pedestal cover 10a faces the opening side X such that the opening is formed in a narrow push-out shape (see FIG. 20), and the side frame on the lower side of the pedestal cover 10a is formed. The inner side surface 131a of the 13a faces the opening side X such that the opening thereof is formed in a wide push-out shape (see Fig. 20), and the side frame 13a on the lower side of the pedestal cover 10a is formed in a notch shape that is engaged with the tying projection of the pedestal. The recess 3. Further, the push-up shape of the inner side surface 121a of the upper side side frame 12a is closer to the lower side side frame 13a, and the inclination of the push-up shape is more moderate, and the vertical direction is close to no push-out, and from the upper side The change transition point 132 of the side frame 12a to the lower side side frame 13a is vertical (refer to FIG. 21), and closer to the concave portion 3 of the lower side side frame 13a, the front end is widened and pushed. The tilt becomes urgent (refer to Figure 20). Moreover, in order to increase the strength of the fitting portion, the lower portion of the side frame 13a on the lower side is configured to be thick.

The frame body of the pedestal cover 10a is a space in which the pedestal main body portion 21a is housed. In the pedestal cover 10a, the inner side surface 121a of the side frame 12a facing the side frame 13a of the recessed portion 3 having a notch shape is narrowed toward the opening side X, that is, the opening side X of the side frame 12a is formed. When the inner side surface 121a of the side frame 12a is formed as a restraining surface from which the pedestal cover 10a is detached from the pedestal, the protruding portion of the pedestal is strongly fitted into the notched recess 3, thereby becoming The upper end portion can fix the base cover 10a, thereby preventing the pedestal cover 10a from coming off the pedestal.

Next, the pedestal of this example will be described with reference to FIG. Figure 22 is a front elevational view of the pedestal of this example. In FIG. 22, the same components as those in FIG. 6 are denoted by the same reference numerals, and the description thereof will be omitted, and only differences will be mainly described herein. That is, the pedestal 20a is made of metal or plastic and has a shape that can be fitted into the pedestal cover 10a. That is, the pedestal 20a has a disk-shaped pedestal main body portion 21a, a tying projection 24 that protrudes downward from the lower end of the pedestal main body portion 21a, and a side surface 26 on the upper side of the pedestal main body portion 21 and the front surface of the pedestal cover In the vicinity of the side, that is, in Fig. 23, the projecting portion 23a (see Fig. 23) is formed on the inner side in the thickness direction of the side surface 26a on the upper side.

The protruding portion 23a enters the inner (bottom) space of the inner side surface of the side frame 12a (upper side) of the pedestal cover 10a, and has a height for accommodating the space for preventing the pedestal cover 10a from coming off the pedestal 20a (see Fig. 23). Further, the length (1) of the protruding portion 23a is as large as one half of the length of the circumference, but if it is about 1/8 to 1/4 of the circumferential length, even if there is an external force in the falling direction, the upper side The moderate frictional force on the inner side of the side frame 12a acts so that it has a point where it is difficult to fall off. Further, the protruding portion 23a and the protruding portion 23 of the pedestal cover 10 may be in the form of a scatter-like dot, and the side surface 26a on the upper side of the pedestal main portion 21a may be formed in a push-up shape that is enlarged inside.
