(1) Structure of cover member for electronic equipment

  The electronic device cover member (hereinafter simply referred to as “cover member”) 1 according to the first embodiment opens the operation surface 51 side of the electronic device 50 and covers the outside of the electronic device 50. It has a form that can. The cover member 1 includes a tray 10 that opens at least in the direction of the operation surface 51, and an elastic member 30 that is lower in hardness than the tray 10 and covers a surface opposite to the opening surface of the tray 10.

  As shown in FIGS. 1 and 3, the tray 10 is configured by connecting a bottom plate 11 positioned on the back side of the electronic device 50 and a side wall 12 extending from the bottom plate 11 toward the outer surface of the electronic device 50. It is a member. The side wall 12 sufficiently covers a pair of side surfaces of the electronic device 50, in this embodiment, both side surfaces on the short side, while the other pair of side surfaces, in this embodiment, both side surfaces on the long side are greatly cut out. Have a shape. The tray 10 has through-holes 15, 16, 17, and 17 formed in the bottom plate 11 and the side wall 12 in accordance with the positions of switches, connection ports, camera lenses, and the like, which are examples of external access units provided on the side surface and bottom surface of the electronic device 50. 19 is provided. Here, the “external access part” refers to a part that can be accessed from either one between the outside of the cover member 1 and the electronic device 50. Access methods include not only direct contact but also light and sound input / output. The tray 10 is preferably made of a resin, more preferably a thermoplastic resin, a thermosetting resin, an ultraviolet curable resin, or an electron beam curable resin, and particularly preferably a polycarbonate resin or a polyester. It consists of a series resin or a polyamide series resin. The thickness of the bottom plate 11 and the side wall 12 of the tray 10 can be designed to an appropriate thickness depending on the size and weight of the electronic device 50. For example, when the thickness of the electronic device 50 is in the range of 8 to 20 mm, the short side is 50 to 200 mm, and the long side is 80 to 300 mm, the bottom plate 11 and the side wall 12 of the resin tray 10 are the thickest portions. It can be designed in the range of 0.4 to 1.4 mm, more preferably 0.4 to 1.0 mm.

  The tray 10 includes one regulation plate 21 erected toward the electronic device 50 on each of the two side walls 12 having the cut-out portions on the long side of the electronic device 50. In addition, the tray 10 includes a plurality of regulating protrusions 22 protruding inward on the two side walls 12 on the short side of the electronic device 50. The restricting plate 21 and the restricting convex portion 22 ensure that the tray 10 inside the cover member 1 is fixed to the outer surface of the electronic device 50 and prevent the electronic device 50 from easily falling off the cover member 1. It is. The restriction plate 21 may be formed not on the side wall 12 on the long side of the tray 10 but on the long side of the bottom plate 11.

  The elastic member 30 is an operation that covers the entire bottom edge of the operation surface 51 of the electronic device 50 from the side wall 32, the side plate 32 that covers the outer surface of the electronic device 50 from the bottom plate 31, and the bottom plate 31 that is located on the back side It is a member having a boat shape configured by connecting the surface side outer edge portion 33 to each other. The elastic member 30 covers the surface on the opposite side of the opening-side inner surface more widely than the opening-side inner surface of the tray 10. As shown in FIG. 2, the elastic member 30 includes a window portion 31 a in which a circle having a diameter of at least 20 mm can be arranged in a region including the center of gravity G of the cover member 1, and the bottom plate 11 of the tray 10 is exposed from the window portion 31 a. . The size of the window 31a is selected from an ergonomic viewpoint because it needs to be large enough for a user's finger using the electronic device 50 to enter. In this embodiment, the shape and size of the window portion 31a are squares of 30 mm in length and width in plan view. The window 31a is preferably formed in a region including the center of gravity G of the cover member 1 when the electronic device 50 is removed from the cover member 1 so that the entire electronic device 50 is located on the opening side of the cover member 1. This is to make it easier to extrude. In addition, the cover member 1 can be reduced in weight by forming the window 31 a in the elastic member 30. However, the position of the window 31 a may be a position that deviates from the center of gravity G of the cover member 1.

  The elastic member 30 is preferably configured from a thermoplastic elastomer, a thermosetting elastomer, or the like, and is particularly preferably configured from, for example, a urethane-based or silicone-based elastomer. When the thickest portions of the bottom plate 11 and the side wall 12 of the tray 10 are in the range of 0.4 to 1.4 mm, more preferably in the range of 0.4 to 1.0 mm, the bottom plate 31 and the side wall 32 of the elastic member 30 made of the elastomer. Can be designed in the range of 0.4 to 1.4 mm, more preferably in the range of 0.4 to 1.0 mm at the thickest part. The elastic member 30 is formed on the bottom plate 31 and the side wall 32 in accordance with the positions of the switch, connection port, camera lens, and the like provided on the side surface and the bottom surface of the electronic device 50, and the convex covering portion 34 and the through holes 35, 36, and 37. , 38, 39. The convex covering portion 34 is preferably formed thinner than other portions so that the electronic device 50 can be touched and operated from the cover member 1. The through holes 35, 36, 37, 38, and 39 are portions formed so as to be in contact with the electronic device 50 or to allow light to pass therethrough. The size, shape, position, and number of the convex covering portion 34 and the through holes 35, 36, 37, 38, 39 vary depending on the form of the electronic device 50.

  The side wall 32 of the elastic member 30 is formed to be higher than the height of the side wall 12 of the tray 10. Even at the highest position in the side wall 12 of the tray 10, the position is in contact with the inner side of the operation surface side outer edge portion 33 of the elastic member 30. Thereby, at least the operation surface side outer edge portion 33 becomes a portion not in contact with the tray 10 and can be freely deformed when being attached to or detached from the electronic device 50. The through holes 35, 36, 37, 39 of the elastic member 30 are formed at substantially the same shape and size at the same positions as the through holes 15, 16, 17, 19 of the tray 10. The elastic member 30 completely covers the outside of the bottom plate 11 and the side wall 12 of the tray 10 except for the window portion 31a, while exposing most of the inside without completely covering the inside thereof. That is, the opening-side inner surface of the tray 10 is not covered by the elastic member 30 and is exposed rather than the outer surface corresponding to the opposite side. For this reason, the inner surface of the tray 10 directly contacts the electronic device 50 in a wide range. The elastic member 30 covers part or all of the inner circumference of at least one of the through holes 15, 16, 17, 19 of the tray 10.

  FIG. 5 is a cross-sectional view taken along line A2-A2 of the electronic device cover member shown in FIG. 1 and shows the state before and after removing the electronic device from the electronic device cover member by pressing from the window portion of the elastic member.

  In FIG. 5, when the electronic device 50 and the cover member 1 are separated from the state (A) in which the electronic device 50 is covered with the cover member 1, one or more windows are formed from the window portion 31 a formed in the elastic member 30. Insert a finger and press the electronic device 50 over the tray 10 (in the direction of arrow F). The electronic device 50 receives the pressure F ′ from the tray 10 and floats in the M direction. As a result, as shown in (B), the electronic device 50 gets over the operation surface side outer edge portion 33 and is detached from the cover member 1. When the elastic member 30 includes the window portion 31a as in this embodiment, it is preferable not to form a through hole in the tray 10 in the region of the window portion 31a. By not providing a through-hole that penetrates both the tray 10 and the elastic member 30, when the electronic device 50 is pushed from there with the finger, the rigidity of the bottom plate 11 of the tray 10 is used, and the entire inner surface of the bottom plate 11 is used. This is because the effect of pushing the electronic device 50 toward the opening side of the cover member 1 is easily obtained.

  6 is a perspective view of a region X when the electronic apparatus cover member shown in FIG. 1 is cut along line A1-A1.

  As shown in FIG. 6, the elastic member 30 covers the outside of the side wall 12 of the tray 10 with the side wall 32, bends from the upper end surface of the side wall 12, and is connected to the operation surface side outer edge portion 33. The side of the cover member 1 has a double structure in which the side wall 12 of the tray 10 is in contact with the inside of the side wall 32 of the elastic member 30. For this reason, the cover member 1 can exhibit high protection against the fall from the side surface of the electronic device 50. Further, since the operation surface side outer edge portion 33 does not include the extending portion of the tray 10 on the inner side, the operation surface side outer edge portion 33 can be deformed in the direction indicated by the arrow P. For this reason, the attachment and detachment of the electronic device 50 and the cover member 1 become extremely easy.

  7 is a cross-sectional view taken along line B-B in a state where an electronic device is attached to the cover member shown in FIG.

  The cover member 1 according to this embodiment functions as a battery lid 58 by being attached to the electronic device 50 in a state where the battery 56 is inserted into the battery housing portion 55 of the electronic device 50. For this reason, in addition to the cover member 1, the electronic device 50 does not need another lid for preventing the battery 56 from dropping off. However, it is not essential that the cover member 1 also serves as the battery lid 58. The battery housing 55 of the electronic device 50 may be provided with a dedicated battery lid, and the cover member 1 may be attached from above.

(2) Manufacturing Method of Electronic Device Cover Member The tray 10 is formed by, for example, an injection molding method in which a molten resin is injected into a mold and molding, or a molding method in which a softened plate-shaped resin is clamped in the mold. Can be suitably manufactured. In the case of the latter molding method, a method of reducing the pressure from one mold side, a method of supplying high-pressure gas from the one mold side, or a method of combining the pressure reduction and the air supply may be used. For example, the elastic member 30 sets the molded tray 10 in a mold, supplies a composition capable of forming the elastic member 30 to the gap between the mold and the tray 10, and crosslinks the composition. It can be formed by a method or the like. When such a molding method is used, the tray 10 and the elastic member 30 can be easily integrated. In order to enhance the adhesion between the tray 10 and the elastic member 30, the elastic member 30 is configured by applying a primer to the adhesion region between the molded tray 10 and the elastic member 30 and then setting the primer. The composition may be supplied into the mold. Alternatively, the tray 10 and the elastic member 30 may be formed separately and the both 10 and 30 may be bonded together.

  Next, a preferred manufacturing method for manufacturing the cover member 1 by the two-color molding method using polycarbonate resin as the material of the tray 10 and silicone elastomer as the material of the elastic member 30 will be described.

  First, a molten polycarbonate resin is injected into a mold capable of shaping the tray 10. Thereafter, when the mold is opened, the tray 10 having the shape shown in FIG. 3 is obtained. Next, a primer is applied to the outer surface of the cover member 1 and dried. Next, the tray 10 coated with the primer is set in another mold capable of shaping the cover member 1, and a molten silicone composition (manufactured by Shin-Etsu Chemical Co., Ltd., product number: KE) is formed in the mold. -2090-40A / B). After the silicone composition is crosslinked, the mold is opened to obtain the cover member 1 including the tray 10 and the elastic member 30. When it is necessary to color or decorate the tray 10, prior to integral molding with the elastic member 30, the tray 10 is dipped into the paint, the paint is applied by spraying, printing, or a decorative sheet May be affixed. Further, when it is necessary to decorate the outer surface of the elastic member 30, after the integral molding with the tray 10, a paint may be applied to the outer surface by spraying, printed, or a decorative sheet may be attached. . Furthermore, the elastic member 30 may be decorated by kneading the pigment in a molten polycarbonate resin in advance and then molding the pigment.

<Second Embodiment>
Next, an electronic device cover member according to a second embodiment of the present invention will be described. In the second embodiment, parts common to the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 8 is a cross-sectional view of the electronic apparatus cover member according to the second embodiment of the present invention as viewed from the same direction as FIG. 6.

  In the electronic apparatus cover member (cover member) 1 according to the second embodiment, the height of the side wall 12 of the tray 10 is lower than that in the first embodiment. As shown in FIG. 8, there is a portion (distance: L) where the tray 10 does not exist between the upper end portion of the side wall 12 of the tray 10 and the inside of the operation surface side outer edge portion 33. For this reason, as indicated by an arrow Q, the side wall 32 of the elastic member 30 can be deformed to a greater extent than the first embodiment in the portion from the upper end of the side wall 12 of the tray 10. As a result, even if the attachment and detachment of the electronic device 50 and the cover member 1 are repeated for a long time, the cover member 1 can reduce the risk of the operation surface side outer edge portion 33 being torn and can withstand long-term use.

<Third embodiment>
Next, an electronic apparatus cover member according to a third embodiment of the present invention will be described. Note that, in the third embodiment, portions that are the same as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 9 is a perspective view of the electronic device cover member according to the third embodiment of the present invention as viewed from the inside. 10 is a perspective view of the electronic device cover member shown in FIG. 9 as viewed from the outside.

  An electronic device cover member (hereinafter referred to as “cover member”) 1 according to the third embodiment is a molded body including a tray 10a and an elastic member 30a. 9, the tray 10a is different from the tray 10 constituting the cover member 1 according to the first embodiment, and the notch of the side wall 12 in the longitudinal direction is reduced to penetrate the tray 10a. An additional side wall 12 a is provided on the longitudinal side surface of the hole 38. Although not clearly shown in FIG. 9, the side walls 12a are formed in pairs at positions facing each other. Further, the elastic member 30a constituting the cover member 1 according to this embodiment includes a circular window portion 31b having a diameter of 20 mm in a region including the center of gravity G of the cover member 1. The said window part 31b is a shape different from the square window part 31a demonstrated in 1st Embodiment, and the magnitude | size is also small. However, the user can easily separate the electronic device 50 and the cover member 1 by inserting a finger from the window 31b and pressing the tray 10a. However, the position of the window portion 31 b may be a position that deviates from the center of gravity G of the cover member 1. In addition, the through-hole 19 is provided with a sheet 60 whose opening is closed with a mesh 61, which is attached from the inside of the tray 10a. For this reason, it is effective when the position of the through hole 19 is the position of the microphone of the electronic device 50.

  FIG. 11 is a cross-sectional view of the region Y when the electronic apparatus cover member shown in FIG. 9 is cut along the line CC.

  The side wall 12 of the tray 10 a is lower than the side wall 32 of the elastic member 30 a and does not reach the inner surface of the operation surface side outer edge portion 33. This point is the same as the cover member 1 according to the second embodiment. As shown in FIG. 11, the side wall 12 of the tray 10a changes in the order of thicknesses t1, t2, and t3 from the bottom plate 11 side toward the tip (t3 <t1 <t2). That is, the side wall 12 is once thickened at the position R and greatly thinned at the position S from the bottom plate 11 side. An upper portion from the position S of the tray 10a is referred to as a thin portion 62 in this embodiment. A suitable thickness t3 of the thin portion 62 is in the range of 0.1 to 0.6 mm under the condition that the thickness t1 is smaller than t1 when the thickness t1 is in the range of 0.3 to 1.0 mm. The side wall 32 of the elastic member 30a that covers the outside of the side wall 12 smoothly covers the outside of the side wall 12 of the tray 10a. The side wall 12 has a thickness t4 at the thickness t1, and at the thicknesses t2 and t3. The thickness changes from the front end of the side wall 12 to the thickness t6 (t5 <t4, t5 <t6). That is, the side wall 32 is once thinned at the position R and thickened again at the position T from the bottom plate 31 side. The thickness t6 of the side wall 32 is preferably in the range of 0.3 to 1.2 mm under the condition that it is thicker than the thickness t3 of the thin portion 62.

  Further, the thickness t6 of the side wall 32 is set to t3 + t5 so that the inner surface of the thin portion 62 and the inner surface of the side wall 32 above the thin portion 62 are substantially flush with each other, and the inner surface of the thin portion 62 and the side wall above it. The inner surface of 32 is not stepped. For this reason, the cover member 1 can be attached so that the side surface of the electronic device 50 is along the inside of the side surface of the cover member 1, and there is no risk that the cover member 1 is easily detached from the electronic device 50. Furthermore, since the upper part from the position S is made thinner, the flexibility from the position S to the upper part is great, and the side wall 12 of the tray 10a is lined from the bottom part to the position T. High impact resistance. Note that the change in thickness in the direction from the position S to the bottom is not limited to the above change. For example, the configuration between the position S and the position T may be extended to the bottom of the cover member 1. Further, the side wall 12 of the tray 10a may be gradually thickened from the position S to the bottom.

  FIG. 12 is a cross-sectional view of the region Z when the electronic apparatus cover member shown in FIG. 10 is cut along line DD.

  The elastic member 30a covers the inner peripheral surface of the through hole 17 of the tray 10a from the bottom plate 31 to form a through hole 37. The inner peripheral surface of the through hole 37 has a step. The elastic member 30a covers the tray 10a in the vicinity of the inside of the tray 10a (from the inside to the thickness H) with the thickness W, and covers the tray 10a in the vicinity of the outside thicker than the thickness W. As a result, the outside of the opening of the through hole 37 is narrower than the inside of the opening. As a result, dust or the like is less likely to enter the electronic device 50 side through the through hole 37. The configuration shown in FIG. 12 can be employed not only in the through hole 37 but also in one or more of the other through holes 35, 36, and 39.

<Fourth embodiment>
Next, an electronic device cover member according to a fourth embodiment of the present invention will be described. Note that, in the fourth embodiment, portions that are the same as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 13: is the perspective view seen from the opening surface side of the cover member for electronic devices which concerns on the 4th Embodiment of this invention.

  As shown in FIG. 13, the tray 10 is a waterproof seal member 70 in a closed loop shape formed of, for example, an elastic member at a position corresponding to the inner periphery of the battery housing 55 of the electronic device 50. Is provided. The waterproof seal member 70 is preferably joined to the tray 10 via an adhesive or by welding. The waterproof seal member 70 may be provided on the inner surface of the tray 10 so as to cover the closed loop-shaped protrusion formed on the inner surface of the tray 10.

<Fifth embodiment>
Next, an electronic apparatus cover member according to a fifth embodiment of the present invention will be described. Note that in the fifth embodiment, parts that are the same as in the first embodiment are given the same reference numerals, and redundant descriptions are omitted.

  FIG. 14: is the perspective view seen from the opening surface side of the cover member for electronic devices which concerns on 5th embodiment of this invention.

  As shown in FIG. 14, the tray 10 b includes a window portion 80 in which a circle having a diameter of at least 20 mm can be arranged in a region including the center of gravity G of the electronic device cover member (cover member) 1. Thirty bottom plates 31 are exposed. The said size of the window part 80 is enough for a user's finger | toe who uses the electronic device 50 to enter similarly to the window part 31a formed in the elastic member 30 which comprises the cover member 1 which concerns on 1st embodiment. Because it is necessary to have a large size, it was selected from an ergonomic viewpoint. In this embodiment, the shape and size of the window portion 80 is a square having a length of 30 mm and a width of 30 mm in plan view. Further, the reason why the window 80 is formed in the region including the center of gravity G of the cover member 1 is the same as the reason described in the first embodiment. However, the position of the window 80 may be a position that deviates from the center of gravity G of the cover member 1. In this embodiment, since the electronic device 50 is pressed through the elastic member 30 having a lower hardness than the tray 10b, compared to pressing the electronic device 50 in a wide range of the bottom plate 11 of the tray 10, The pressing area is reduced. However, since the electronic device 50 can be pressed with an area larger than the area of the finger that contacts the elastic member 30 in the region of the window 80, the electronic device 50 can be used instead of directly pressing the finger against the electronic device 50. And the cover member 1 can be easily separated. In addition, weight reduction of the cover member 1 can also be achieved by forming the window part 80 in the tray 10b.

<Other embodiments>
The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. .

  For example, depending on the positions of buttons, speakers, camera lenses, etc. of the electronic device 50, the through holes 16 may not be provided in the trays 10, 10a, 10b, and only the operation surface 51 side of the electronic device 50 may be opened. . In the case where the elastic members 30, 30a cover the inner peripheral ends of the through holes 15, 16, 17, 19 of the trays 10, 10a, 10b, the elastic members 30, 30a are connected to the trays 10, 10a, 10b from the inner peripheral ends. It may be formed so as to reach the inner surface. Thereby, the waterproof effect and the dustproof effect can be further enhanced. Furthermore, the elastic members 30, 30a do not have to cover even the inner peripheral ends of the through holes 15, 16, 17, 19 of the trays 10, 10a, 10b. As long as the elastic members 30 and 30a cover the surface on the opposite side more widely than the inner surface on the opening side of the trays 10 and 10a, compared to the first embodiment, the elastic members 30 and 30a The portion may be covered more widely, or the surface opposite to the opening-side inner surface of the tray 10, 10a, 10b may be exposed. Furthermore, the trays 10, 10a, 10b and the elastic members 30, 30a are preferably in close contact with each other, but there may be regions that are not in close contact. Moreover, the elastic members 30 and 30a do not necessarily need to form the side wall 32 more than the height of the side wall of the trays 10, 10a, and 10b. Further, the elastic members 30 and 30 a do not necessarily have to include the operation surface side outer edge portion 33 that is connected from the side wall 32 and covers part or all of the outer edge of the operation surface 51 of the electronic device 50. When the window portions 31a and 31b are formed in the elastic member 30, the trays 10 and 10a are made of a material having excellent translucency, and at least the areas of the window portions 31a and 31b of the trays 10 and 10a are not shielded from light. Then, the electric display of the electronic device 50 can be visually recognized through the window portions 31a and 31b.

  The first embodiment, the second embodiment, the third embodiment, the fourth embodiment, and the fifth embodiment described above are the features of each other, unless particularly combined. One or more may be combined. Therefore, the combination of the first embodiment and the fifth embodiment forms a through hole that exposes the electronic device 50 to the outside in the region including the center of gravity G of the cover member 1. It is not possible. Except for the case similar to such illustration, the embodiments can be arbitrarily combined. For example, the cover member 1 according to the first embodiment also serves as the battery lid 58, but may also serve as the battery lid 58 in other embodiments. Moreover, the side wall 12a shown in FIG. 8 existing in the third embodiment may be provided in each cover member 1 according to the first embodiment, the fourth embodiment, or the fifth embodiment. . The waterproof seal member 70 provided in the cover member 1 according to the fourth embodiment may be provided in each cover member 1 according to the first to third embodiments or the fifth embodiment.

  The present invention can be used as a protective cover for electronic devices.
