Description

  The present invention relates to an electronic device such as a mixer, and more particularly to an electronic device such as a mixer in which a side pad can be disposed on the outermost surface.

  The side pads are generally fixed to the mixer body by screws from the outer surface. In this case, since the screws are exposed on the outer surface, it is easy to remove and attach the side pads. However, since the screws are visible on the appearance, the design is inferior. There is also a structure in which the side pad is screwed from the inside of the mixer body. In this case, since there is no screw in the appearance, the design is excellent. However, unless the panel of the mixer main body is opened, the screw cannot be removed and attached, and the side pad removal and attachment becomes troublesome.

FIG.

  Hereinafter, a mixer according to an embodiment of the present invention will be described with reference to the drawings.

  1A and 1B are a perspective view of the entire mixer and a plan view schematically showing the connection between the mixer body and the side pads. For example, a flat base plate CP is attached to the side plate of the mixer body MM. The base plate CP is a member for attaching the side pad SP, and can be removed when not needed. For example, the base plate CP is manufactured by processing an aluminum flat plate having a thickness of 6 mm. As shown in FIG. 1A, when viewed obliquely from above, only the resin cover of the side pad is visible, and the base plate CP and the screw for fixing the side pad are not visible. It is possible to provide a design with excellent appearance.

  FIG. 2A is a front view of the base plate CP disposed on the side surface of the mixer body as viewed from the inside. 2B is a cross-sectional view taken along line 2B-2B shown in FIG. 2A. The base plate CP has a planar shape included in the side pad, and has a plurality of through-holes 11, for example, rectangular, through which a hook described later can pass from the outside. For example, a rectangular longitudinal groove 12 is formed by removing the inner side of the base plate CP, for example, about half of the thickness, continuously from the upper side of each through hole 11, and the remaining portion constitutes the hook position defining portion 13. . The longitudinal groove 12 receives the hook when the hook is inserted and slid upward. The upper surface of the longitudinal groove 12 or the lower surface of the hook position defining portion 13 is engaged with the hook. The inner surface of the hook position defining portion 13 cooperates with the side plate of the mixer body MM to define the horizontal position of the hook. The through hole 11, the vertical groove 12, and the hook position defining portion 13 constitute a fitting hole 15 that functions as a hook susceptor. The upper part of the through-hole 11 and the vertical groove 12 constitute a hook corresponding locking part 14 that accommodates the hook moved upward.

  FIG. 3A is a rear view of the side pad SP as viewed from the inside. The side pad SP includes a plurality of metal frames MF inside a resin cover RC that governs the appearance. The resin cover RC has a shape that matches the shape of the side surface of the mixer body MM, and is bent twice in the illustrated configuration. The metal frame MF is formed of a bent metal plate (for example, an iron plate) in order to increase the strength of the side pad SP. The metal frame MF is divided into three portions MF1, MF2, and MF3 that are not bent. Hereinafter, the metal frame MF1 having the widest lowermost layer will be described as an example. Other metal frames have a similar structure.

  3B and 3C are a front view of the metal frame MF1 viewed from the outside and a side view of the metal frame MF1 viewed from the right side of FIG. 3B. FIG. 3D is a perspective view of the metal frame MF1 as viewed obliquely from above and outside. The metal frame MF is made from a metal plate. As shown in FIG. 3B, the right side of the rectangular metal plate 20 becomes a hypotenuse that narrows the width downward from a predetermined position from above, and the lower side again becomes a vertical side. Further, a stripe-shaped portion 27 that forms the screw hole 28 is formed so as to protrude at a predetermined position below. The metal plate 20 is bent with the horizontal direction as an axis. For example, the rectangular cutout 22 has a side and a lower side cut and bent to the back side of the paper, and then bent upward to form a hook, leaving an opening later. A plurality of screw holes 24 for connecting the metal frame MF1 to the resin cover RC are formed.

  As shown in the side view of FIG. 3C, the upper portion of the metal plate 20 is bent twice in the left direction to form a top portion 21 having a U-shaped cross section having a top surface and both side surfaces and projecting outward on the left side. The cut-out portion 22 is once bent rightward (inward) and then bent upward to form a hook 23. The rectangular portion below the hypotenuse is bent into a U-shape projecting outward (left) to form the inflatable portion 26. The expansion part 26 has an upper and lower surface projecting to the left side and a side surface connecting the upper and lower projecting parts. The striped portion 27 having a screw hole extends from the lower surface of the inflating portion 26, is bent downward, and is then bent into a crank shape.

  As shown in the perspective view of FIG. 3D, the metal plate 20 forms a U-shaped top portion 21 at the upper portion, and forms a U-shaped expansion portion 26 at the lower portion. If the metal plate is angled, the strength can be increased. The cut portion 22 is bent to form a hook 23 projecting inward.

  As shown in FIG. 3A, when each side pad SP is divided into linear portions, there are three portions. Metal frames MF1, MF2, and MF3 are formed together with the respective linear portions. By dividing the side pad SP into straight portions, the metal frame MF can be angled. The number of divisions is not limited to three. The number of divisions is arbitrary according to the shape of the side pad.

  4A and 4B are a rear view of the resin cover RC of the side pad as seen from the inside and a front view as seen from the outside. FIG. 4C is a cross-sectional view of the resin cover RC of the side pad along the line 4C-4C in FIG. 4B. As shown in FIGS. 4A and 4C, the resin cover RC includes a portion constituting the exterior portion 31 and a rib-like protrusion 33 inside the exterior portion. The rib-shaped protrusions 33 are arranged in a lattice shape, and ensure the strength of the side pads SP. As shown in FIG. 4B, a concave portion 36 serving as a nameplate housing portion is also formed on the outer side surface. As shown in FIG. 4A, screw holes 35 are formed in some of the intersecting portions of the rib-like protrusions 33. As shown in FIG. 4C, the rib-like protrusion 33 is formed. The metal frame accommodating part 34 for metal frame MF reception is comprised. The side pad SP is formed by housing the metal frame MF in the metal frame housing portion 34 and screwing it. The metal frame accommodating portion 34 constitutes a second fitting portion that accommodates the expanding portion 26. The exterior part 31 of the side pad SP has a shape that accommodates the metal frame MF inside and projects outward.

  An operation for coupling the metal frame MF of the side pad described above to the base plate attached to the mixer body will be described.

  5A-5C are cross-sectional views illustrating an operation of attaching the side pad to the base plate CP.

FIG. 5D is a side view showing the relationship between the side plate 18 of the mixer body and the side pad SP. A region where the side pad SP is disposed on the side plate 18 of the mixer body is indicated by a broken line. A plurality of screw holes 19 are formed in the side plate 18 of the mixer body immediately below the region where the side pads are arranged. The base plate CP is fixed to the side plate 18 with screws or the like. 5A-5C, the side plate 18 is not shown.
As shown in FIG. 5A, the side pad SP is carried to the side surface of the base plate CP, the metal frame hook 22 is opposed to the through hole 11 of the base plate CP, and the through hole 11 is passed. As shown in FIG. 5B, after the hook 22 passes through the through hole 11, the side pad SP is lifted upward, and the hook 22 is inserted into the longitudinal groove 12. As shown in FIG. 5C, the hook 22 contacts the base plate CP for positioning. Although the case where the horizontal portion of the hook 22 is in contact with the lower surface of the hook position defining portion 13 is shown, the vertical portion of the hook may be in contact with the upper surface of the longitudinal groove 12. The vertical position of the side pad SP is defined by at least one of these two types of abutments. The horizontal position of the hook is determined by utilizing the engagement between the vertical portion of the hook and the hook position defining portion 13 (and the side plate 18). At this time, the screw holes 28 of the striped portion 27 below the metal frame are aligned with the corresponding screw holes of the mixer body MM.

  FIG. 5E is a perspective view of the state in which the screw is fixed to the mixer body through the through hole of the metal frame MF after hook engagement, as viewed from below. As shown in FIG. 5E, a screw 29 is inserted into the screw hole 28 and fixed to the screw hole 19 of the side plate 18 of the mixer body. The side pad SP is fixed with screws. Unless the screw is removed, the side pad SP cannot be slid to remove the hook. The hook 22 and the hook position demarcating portion 13 or the upper surface of the longitudinal groove 12 are in contact with each other to form a structure capable of carrying weight. The hook 22 has a finite R by bending, and can improve the horizontal positioning function. The side pad SP has a shape projecting outward, and the screw 29 is disposed immediately below the side pad SP. Therefore, the screw 29 cannot be seen at a normal line-of-sight position. In this state, the side pad SP is fixed to the mixer body MM. When the side pad SP is lifted, the mixer body MM can be lifted via the hook 22.

  6A and 6B are a perspective view and a rear view, as seen from the inside, of the engagement state between the side pad SP and the base plate CP attached to the mixer body. The hook 22 that has passed through the fitting hole 15 of the base plate CP is engaged with the fitting hole 15 of the base plate CP. A striped portion 27 having a screw hole of a metal frame protrudes from below the base plate CP.

  FIG. 6C is a cross-sectional view taken along the line 6C-6C in FIG. The exterior portion 31 of the resin cover RC is in contact with the base plate CP and is positioned in the lateral direction. The metal frame MF is accommodated in the metal frame accommodation portion 34 defined by the rib-like protrusions 33 of the resin cover RC. The hook 22 of the metal frame MF is fitted in the fitting hole 15 of the base plate CP. In the illustrated portion, the metal frame MF is covered with a resin cover RC and is not exposed to the outside. The nameplate housing portion 36 of the resin cover RC has a concave portion on the surface, and also functions to enhance the strength of the resin member.

  6D and 6E are a front view of the side pad SP viewed from the outside and a side view of the side pad SP viewed from the front. Only the striped portion 27 with screw holes extends outside the resin cover RC. As shown in FIG. 6E, since the screw portion is disposed immediately below the raised portion of the side pad, the screw portion does not enter the field of view and does not impair the appearance as seen from above.

  7A and 7B are a cross-sectional view and a partially enlarged view showing a coupling structure of the side pad SP, the side plate 18 and the base plate CP of the electronic device main body according to another embodiment, and FIG. 7C is a perspective view of the spring member 42. FIG.

  As shown in FIG. 7A, the hook position defining portion 13 of the base plate CP includes an inner surface having a taper, and defines the horizontal position of the hook 22 with high accuracy. As shown in FIGS. 7A and 7B, a through hole 47 is formed in the side plate 18 of the electronic apparatus main body instead of the screw hole. A plurality of tongue pieces 41 protrude from the lower side of the metal frame MF, and a spring member 42 formed by, for example, outsert molding is engaged with the tongue pieces 41 to constitute a pressure contact means 40.

  As clearly shown in FIGS. 7B and 7C, the spring member 42 has a U-shape as a whole and constitutes a spring, and has protrusions including a first inclined portion 43 and a second inclined portion 44 on the outer side of the tip. When the spring member 42 is pushed into the through hole 47 of the side plate 18, the spring is pushed and bent by the first inclined portion 43. When passing through the protrusion, the spring returns while moving along the second inclined portion 44. The second inclined portion 44 exerts a pressing force on the through hole 47. The side pad SP is removed by deforming the spring member 42.

  As mentioned above, although this invention was demonstrated along the Example, this invention is not limited to this. For example, you may provide the side pad which improves aesthetics in electronic devices other than a mixer. The hook is not limited to one formed by bending a rectangular piece. For example, you may form from a triangle piece etc. Instead of making the through-hole 11 rectangular, the trapezoidal shape whose width decreases upward can be easily inserted, and positioning when the hook is lifted up can be made highly accurate. It will be apparent to those skilled in the art that various other changes, substitutions, improvements, combinations, and the like can be made.
