Description

  The present invention relates to a housing provided with a hinge, and more particularly to a housing that is installed to accommodate electronic equipment such as communication equipment.

  The housing for housing objects has a housing body in which an opening for housing these objects is formed, and a lid for covering the opening and ensuring the airtightness of the housing. There is. In some cases, a hinge composed of a rotating shaft and blades that can rotate in the circumferential direction of the rotating shaft is disposed across the main body and the lid so that the lid can be opened and closed.

  There are various types of hinges. For example, when the hinge is composed of one rotating shaft and two blades connected to the rotating shaft with the rotating shaft sandwiched, one blade is fixed to the housing body. The other blade is fixed to the lid. Since the hinge blades are each rotatable in the circumferential direction of the rotation shaft, the lid (housing body) can be rotated (rotated) in a direction toward or away from the housing body (lid). That is, the housing body and the lid body rotate relative to each other.

  When such a casing is used for the purpose of accommodating an electronic device such as a communication device, for example, a set of keys, clasps (for example, hook-shaped ones), etc., so that the lid does not open without permission. Fixing means composed of a plurality of members may be divided and attached to a housing body and a lid (see, for example, Patent Document 1). When the lid is closed and the fixing means is functioning, the lid and the casing main body are fixed by the fixing means, so that the relative rotation between the casing main body and the lid is prevented, and the casing Relative sliding in the contact surface direction between the main body and the lid is also prevented.

JP 2004-31660 A (paragraphs 0022 to 26, FIGS. 1 to 3)

  The housing that houses the electronic device is in a vertical state, that is, the hinge rotation axis (or the contact surface between the housing body and the lid) is orthogonal to the ground surface or the floor surface, and is predetermined from the ground or floor surface. May be installed on poles or poles at a distance.

  Since a space is formed between the lid and the floor surface, the lid tends to fall by its own weight while the lid is open. However, since the hinge blades are fixed to both the housing body and the lid body, the lid body is supported by the hinge blades attached to the housing body supported by the poles and pillars, and drops. It is blocked. While the lid is closed, the lid is supported by a hinge and fixing means. Depending on the mode of the fixing means, the lid is supported only by the hinge.

  Since the hinge and the fixing means or only the hinge supports the lid while the lid is closed, an external force that causes relative sliding in the in-plane direction of the contact surface between the housing body and the lid. When this occurs, the hinge (and fixing means) resists this external force. Therefore, the hinge (and the fixing means) may be deformed.

  When the hinge is deformed, the relative rotation direction of the housing main body and the lid changes, so that the lid cannot be completely closed, resulting in problems such as poor appearance and reduced waterproof function. In addition, the deformation of the fixing means also causes problems such as poor appearance and reduced function or invalidity of the fixing means. Such a defect may be caused not only by the deformation of the hinge and the fixing means, but also by the displacement of the lid body due to such rattle and play.

  Furthermore, when the casing is molded from steel or the like, the weight of the lid is increased, so that the hinge (and fixing means) supports the lid for a long period of time without external force acting. And fixing means) to the housing body and the lid body are deteriorated (for example, the fixing strength is reduced). As a result, there arises a problem that the interval for maintenance of the housing is shortened. This deterioration is particularly noticeable when the hinge and the fixing means are fixed to the housing main body and the lid by screws, for example.

  In order to prevent the deformation of the hinge and the fixing means and prevent the occurrence of problems, it is assumed that the strength of the hinge and the fixing means is increased, but this is not preferable because the cost of the hinge and the fixing means increases.

  An object of the present invention has been made in view of such a problem, and is to provide a housing for an electronic device that prevents displacement of a lid attached to the housing body by a hinge and a fixing means with respect to the housing body. .

  The invention according to claim 1 is provided with a casing main body that accommodates an electronic device and a lid body that is connected to the casing main body via a hinge, and the rotation axis direction of the hinge coincides with the vertical direction. A casing for electronic equipment to be installed, the fixing means installed on the casing body and the lid, and preventing rotation of the lid when the lid is closed; An insertion member having a convex portion provided on one of the lids and the convex portion provided on the other of the housing main body or the lid when the lid is closed And a fitted member having a recessed portion, and the fitting prevents movement of the lid in the vertical direction.

  As described above, the present invention is provided with a convex portion provided on one of the casing main body and the lid, and provided on the other of the casing main body and the lid, and the convex portion is fitted when the lid is closed. And the lid is prevented from moving in the vertical direction by the fitting of the projection and the recess when the lid is closed, so the casing of the lid attached to the casing main body by the hinge and the fixing means. Deviation from the body can be prevented.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
1A and 1B show specific examples of the electronic device casing of the present invention. The housing 10 for electronic devices (hereinafter referred to as the housing 10) accommodates an electronic device such as a communication device, for example, the housing body 2 in which the opening 2a is formed, covers the opening, and the airtightness of the housing 10 And a lid 3 for securing The housing body 2 and the lid body 3 are connected via a hinge 4, and the direction in which the lid body 3 (housing body 2) approaches or separates from the housing body 2 (lid body 2) by the hinge 4. The casing main body 2 and the lid body 3 are freely rotatable relative to each other. The type of material of the housing 10 is not limited. For example, the housing 10 is molded from a synthetic resin, fiber reinforced plastic, or the like in addition to a metal such as a steel material or an aluminum alloy.

  The hinge 4 may be of any form, but in the present embodiment, the hinge 4 composed of the rotating shaft 41 and the blade 42 that is rotatable in the circumferential direction of the rotating shaft 41 is connected to the housing body 2. It is installed across the lid 3. In FIG. 1A and FIG. 1B, two blades 42 are connected to the rotation shaft 41 with the rotation shaft 41 sandwiched therebetween.

  One blade 42 is fixed to the housing body 2, and the other blade 42 is fixed to the lid 3. Since the blades 42 of the hinge 4 are respectively rotatable in the circumferential direction of the rotation shaft 41, the lid body 3 is rotatable (rotated) in a direction approaching or separating from the housing body 2. That is, the housing body 2 and the lid body rotate relative to each other.

  As shown in FIGS. 1 (a) and 1 (b), the casing is placed on a ground or floor surface in a vertically oriented state, that is, in a state where the rotation axis 41 of the hinge 4 is aligned with the vertical direction, on a column A such as a pole. It is installed at a position at a predetermined distance from.

  The casing 10 is provided with a fixing means 5 that prevents the lid 3 from opening when the lid 3 is closed, that is, the relative rotation between the casing body 2 and the lid 3. . Although the form of the fixing means 5 is not limited, in the drawing, the fixing means 5 includes a movable hook-like member 51 attached to either the casing body 2 or the lid 3, and the casing body 2 or the lid 3. It consists of a hook receiving member 52 attached to either one. As shown in FIG. 1 (c), when the lid 3 is closed, the hook member 51 is moved and hooked on the hook receiving member 52 to be fixed, whereby the casing body 2 and the lid 3 are rotated relative to each other. Is blocked.

  Furthermore, the housing 10 is provided with restraining means 1 that prevents relative sliding between the housing body 2 and the lid 3 when the lid 3 is closed. The restraining means 1 includes an insertion member 11 having a convex portion 11a disposed on one of the housing main body 2 and the lid 3, and an inserted member 12 having a concave portion 12a disposed on the other side. . When the lid 3 is closed, the convex portion 11 a is fitted into the concave portion 12 a so that the convex portion 11 a and the concave portion 12 a are fitted, and the housing body 2 and the lid body 3 are formed between the housing body 2 and the lid body 3. Since they are mutually constrained in the in-plane direction (hereinafter referred to as in-plane direction) of the surface including the contact surface, each in-plane direction movement (relative sliding) is prevented.

  When the housing body 2 is fixed to the column A such as a pole and a space is formed below the lid body 3 as in the present embodiment, the housing body 2 and the lid body 3 due to the weight of the lid body 3 Tries to slide relative to the direction of the rotation axis 41 of the hinge 4, but the relative movement is prevented by fitting the convex portion 11a and the concave portion 12a. Further, the restraining means 1 prevents relative sliding of the housing body 2 and the lid body 3 due to an external force other than the weight of the lid body 3.

  At this time, since the restraining means 1 bears its own weight and external force of the lid 3, no load is applied to the hinge 4 and the fixing means 5, so that the hinge 4 and the fixing means 5 are deformed, and the lid due to play and rattling thereof. The displacement of the body 3 is prevented. Accordingly, the appearance defect due to the deformation of the hinge 4 or the fixing means 5 or the displacement of the lid 3, the waterproof function of the housing 10 is lowered or invalidated, and the functions of the hinge 4 or the fixing means 5 itself are deteriorated or invalidated. It can be avoided. In particular, when the side wall 22 of the housing body 2 is lowered and the side wall 32 of the lid body 3 is raised to improve the maintainability of the built-in electronic device, the weight of the lid body 3 increases and the lid body 3 Since the deviation is likely to occur, the above-described effect is remarkable.

  In FIGS. 1A and 1B, the insertion member 11 is provided on the lid 3, and the insertion member 12 is provided on the housing body 2. Here, when the lid 3 of the lid 3 is closed, the convex portion 11a projects from the end surface that contacts the housing body 2. However, the convex portion 11a does not project from the end surface, and the inserted member 12 does not project. The housing body 2 may have a structure that protrudes from an end surface in contact with the lid body 3 when the lid body 3 is closed, and the concave portion 12a is formed on the lid body 3 side from the end surface.

  That is, it is only necessary that either the convex portion 11a or the concave portion 12a protrude from the end face so that the convex portion 11a and the concave portion 12a are fitted when the lid 3 is closed. Moreover, although the recessed part 12a is formed from the one end surface of the to-be-inserted member 12 to the middle of the direction in which the convex part 11a is inserted in drawing, it may be formed through the to-be-inserted member 12.

  The housing body 2 includes, for example, a bottom plate 21 and side walls 22 (22A to 22C) standing from the bottom plate 21, and an end portion of the side walls 22 (22A to 22C) connected to the bottom plate 21 ( In FIG. 1A, an opening 2a is formed by being surrounded by an end opposite to the end located on the left side (the end located on the right side in FIG. 1A). Similarly, the lid 3 includes a bottom plate 31 and side walls 32 (32 </ b> A to 32 </ b> C) standing from the bottom plate 31.

  Since it is only necessary to close the opening 2 a of the housing body 2, the lid 3 may be composed of only the bottom plate 31. Moreover, the housing body 2 may have a mode in which the side wall 22 has a top plate at the end opposite to the end connected to the bottom plate 21 and an opening is formed in the top plate.

  As shown in FIG. 1B, with the lid 3 closed, the outer surface of the side wall 22 of the housing body 2, the outer surface of the side wall 32 of the lid body 3, and the inner surface of the side wall 22 of the housing body 2 The inner surface of the side wall 32 of the lid 3 is connected to be flush with each other. At this time, the end surface of the side wall 22 of the housing body 2 and the end surface of the side wall 32 of the lid 3 come into contact with each other to form a contact surface. When the lid 3 is composed of only the bottom plate 31, the surface of the lid 3 facing the housing main body of the bottom plate 31 and the end surface of the side wall 22 of the main body 2 are in contact with each other to form a contact surface.

  In the drawing, one blade 42 of the hinge 4 is fixed to the outer surface of the side wall 22 of the housing body 2, and the other blade 42 is adjacent to the side wall 22 to which one blade 42 is fixed when the lid 3 is closed. The lid 3 is fixed to the outer surface of the side wall 32. The place where the blade | wing 42 is installed is suitably set according to the structure and shape of the housing body 2 and the lid body 3, or the aspect of the hinge 4. The fixing method of the hinge 4 is appropriately selected depending on the material of the housing body 2 and the lid body 3.

  The rotation shaft 41 of the hinge 4 includes a plane including the end face of the side wall 22 of the housing body 2 (hereinafter abbreviated as a main body plane) S1 and a plane including the end face of the side wall 32 of the lid 3 (hereinafter abbreviated as the lid body plane). ) Located on the line of intersection with S2 and disposed on the surface including the contact surface between the housing body and the lid, which is formed when the lid is closed.

  In the drawing, a hook receiving member 52 is attached to the side wall 22B of the housing body 2 that faces the side wall 22A of the housing body 2 on which the hinge 4 (one blade 42) is installed, and the hinge 4 (the other blade 42). The hook-shaped member 51 is installed on the outer surface of the side wall 32B of the lid 3 that faces the side wall 32A of the lid 3 where the

  On the other hand, the fitting member 11 of the restraining means 1 is provided on the inner surface of the side wall 32A of the lid 3 to which the hook-like member 51 is attached, and the fitted member 12 of the restraining means 1 is a housing to which the hook receiving member 52 is attached. It is provided on the inner surface of the side wall 22 </ b> A of the body body 2. The restraining member 1 may be provided on the outer surface of the housing 10, but the inner surface of the housing 10 is preferable because the appearance can be simplified.

  In FIG. 1A, the insertion member 11 is provided in a state in which the direction of the axis X of the convex portion 11a is orthogonal to the lid surface S2, and the insertion member 12 has the direction of the axis Y of the concave portion 12a in the main body plane S1. It is provided in a state orthogonal to. That is, when the lid 3 is closed, the convex portion 11 a and the concave portion 12 a that are fitted are orthogonal to the contact surface between the housing body 2 and the lid body 3. Therefore, even if an external force that causes the housing body 2 and the lid 3 to slide relative to each other acts on the housing 10 when the lid 3 is closed, the axis X of the convex portion 11a (of the concave portion) Since no force is generated to release the direction component of the axis Y), that is, the fitting state of the convex portion 11a and the concave portion 12a, relative sliding can be reliably prevented.

  In addition, since the restraining member 1 is provided on the side walls 22B and 32B facing the side walls 22A and 32A to which the hinge 4 is fixed, under the condition that the restraining member 1 is provided on the inner surface of the housing 10 The rotation radius R1 of the convex portion 11a and the rotation radius R2 of the concave portion 12a are maximized. Here, the rotation radius R1 of the projection 11a is the distance between the rotation axis 41 of the hinge 4 and the axis X of the projection 11a, and the rotation radius R2 of the recess 12a is the rotation axis 41 of the hinge 4 and the recess 12a. This represents the distance from the axis Y. In the present embodiment, the turning radius R1 and the turning radius R2 are the same.

  As shown in FIG. 2A, assuming that the axial length and the installation position of the convex portion 11a and the concave portion 12a are constant, the tip of the convex portion 11a becomes larger as the rotation radius R1 (rotation radius R2) is larger. Is smaller than the angle θ1 formed between the main body plane S1 and the cover plane S2 when it approaches the recess 12a (the end surface on the lid side), in other words, the angle θ1 formed between the axis X of the projection 11a and the axis Y of the recess 12a. As shown in FIG. 2B, when the convex portion 11a rotates in the concave portion 12a, the position of the tip of the convex portion 11a in the direction of the rotation radius R2 and the axis X of the convex portion 11a and the axis Y of the concave portion 12a. The angle θ1 formed changes. As the lid 3 approaches the closed state, the tip end of the convex portion 11a moves outward in the direction of the radius of rotation R2, and the axis X direction of the convex portion 11a and the direction of the axis Y of the concave portion 12a approach each other.

  The larger the angle θ2 formed between the axis X of the projection 11a and the axis Y of the recess 12a when the projection 11a reaches the recess 12a (the end surface on the lid 3 side), the longer the projection 3 is until the lid 3 is closed. The length of the recess 12a in the direction of the rotation radius R2 that is necessary for the 11a to maintain the fitted state in the recess 12a is increased. When the lid 3 is closed, the axis X direction of the convex portion 11a coincides with the axis Y direction of the concave portion 12a. Therefore, when the length L of the concave portion 12a in the rotation radius R2 direction is increased, the lid body 3 is closed. Since a gap is formed between the convex portion 11a and the hole wall of the concave portion 12a, the housing body 2 and the lid 3 cannot be restrained each other. As a result, relative sliding between the housing body 2 and the lid body 3 cannot be reliably prevented. Therefore, in the present embodiment, the location of the restraining means 1 is optimally the side walls 22B and 32B facing the side walls 22A and 32A to which the hinge 4 is fixed.

  As shown in FIG. 1C, if the cross section perpendicular to the axis X of the convex portion 11a is a shape that decreases toward the tip of the convex portion 11a, the convex portion 11a does not contact the hole wall of the concave portion 12a. Since the inside of the concave portion 12a can be easily rotated, a decrease in strength due to damage to the insertion member 11 and the insertion member 12 due to the hole wall and impact of the concave portion 12a of the convex portion 11a can be avoided.

  Further, in FIGS. 1A and 1B, the fitting member 11 is fitted in the corner portion formed by the inner surface of the side wall 32B and the inner surface of the side wall 32C, and is fitted in the corner portion formed by the inner surface of the side wall 22B and the inner surface of the side wall 22C. A member 12 is provided. The fitted member 12 abuts on the side wall 22B of the housing body 2 and abuts on the side wall 22C on either side of the hinge 4 in the direction of the rotation axis 41.

  When the housing body 2 or the lid body 3 receives an external force in the direction of the rotation axis 41 of the hinge 4 and the fitting member 11 attempts to move relative to the side wall 22C side to which the fitting member 12 is connected, the fitting member 12 is inserted. Receives a reaction force from the side wall 22C. Further, the housing body 2 or the lid body 3 receives an external force in the direction of the rotation axis 41 of the hinge 4 so that the fitting member 11 is relatively moved to the side wall 22C opposite to the side wall 22C to which the fitting member 12 is connected. In doing so, the inserted member 12 receives a tensile force from the connected side wall 22C. That is, since the inserted member 12 can obtain a resistance force in addition to the joining force with the side wall 22B of the housing body 2 against the external force of the hinge 4 in the direction of the rotation axis 41, the strength of the restraining means 1 is increased.

  As shown to Fig.3 (a), the slope 12b which spreads outward toward the front-end | tip and is inclined is formed in the edge part of the side into which the convex part 11a inserts of the recessed part 12a. As described above, since the tip of the convex portion 11a moves outward in the direction of the radius of rotation R2 as the lid 3 approaches the closed state, if the inclined surface 12b that extends toward the tip is formed in the concave portion 12a. The convex portion 11a can rotate in the concave portion 12a without contacting the hole wall of the concave portion 12a.

  Further, even if the convex portion 11a is displaced outward in the rotation radius R2 due to a manufacturing error or the like, the convex portion 11a comes into contact with the inner wall of the inserted member 12 during the movement, and the inclined surface 12b Accordingly, the convex portion 11a can be forcibly inserted into the concave portion 12a.

  As shown in FIGS. 1 (c), 3 (a), and 3 (b), a portion that fits with the convex portion 11a (hereinafter referred to as a fitting portion) excluding a portion where the inclined surface 12b of the concave portion 12a is formed. The portion that fits into the recess 12a (hereinafter referred to as the fitting portion), excluding the portion where the cross section of the convex portion 11a is reduced, has a cylindrical shape, and a cross section that is perpendicular to the axis Y of the fitting portion of the concave portion 12a. The cross sections orthogonal to the axis X of the fitting portion of the convex portion 11a are congruent.

  Therefore, when the lid 3 is closed and the convex portion 11a is fitted into the concave portion 12a, the convex portion 11a and the concave portion 12a are restrained in the radial direction within the plane orthogonal to the axis X (axis Y). Relative movement in the in-plane direction including the surface of the contact surface between the housing body 2 and the lid body 3 orthogonal to the (axis Y) is restrained.

  Since the cross-sectional shape of the fitting portion of the convex portion 11a matches the cross-sectional shape of the fitting portion of the concave portion 12a, the cross-section of the concave portion 12a is minimized, so that the material of the inserted member 12 can be reduced. it can.

  Further, the fitting member 11 and the fitted member 12 can be detachably attached to the lid 3 and the housing body 2, and in this case, only the restraining means 1 is replaced when the function of the restraining means 1 is reduced or expires. If it is, the function of the whole housing 10 can be maintained, and it is economical.

(Other embodiments)
The present invention is not limited to the above embodiments. The above-described embodiment is merely an example, and any structure having substantially the same configuration as the technical idea described in the claims of the present invention and having the same function and effect can be used. It is included in the technical scope of the present invention.

  For example, the convex part 11′a of the fitting member 11 ′ and the concave part 12′a of the fitting member 12 ′ are molded so that the cross section perpendicular to the respective axes X and Y has a square shape (rectangular shape in the drawing). Can do. As an example, as shown in FIGS. 4A to 4C and FIGS. 5A to 5C, the convex portion 11a ′ has a planar shape, and the concave portion 12a ′ and the inclined surface 12b ′ are planar. It has a viewing-like annular shape. In this case, since the contact portions with the side walls 22B and 32B are larger than in the first embodiment, the strength against the external force or the like of the restraining means 1 'increases.

  As the lid 3 approaches the closed state, the tip of the convex portion 11a ′ moves outward in the direction of the radius of rotation R2. Therefore, in order to avoid contact between the convex portion 11a ′ and the hole wall of the concave portion 12a ′, It is preferable to incline the tip of the portion 11a ′ inward in the direction of the rotation radius R1.

  Further, since there is a risk of injuries or damage to stored articles when the housing 10 is used, in order to avoid such a risk, the tip of the convex portion 11a ′ is formed in a curved shape. Is also preferable.

  Furthermore, for example, if a groove is formed in the entire periphery of the end surfaces of the side walls 33 and 22 of the lid 3 or the housing body 2 and a waterproof packing is installed in the groove, the airtightness (waterproofness) of the housing 10 is improved. This is preferable.

  In addition, the insertion member 11 can be provided in the housing body 2, and the insertion member 12 can be provided in the lid body 3. In this case, the same operation / effect as the above-described operation / effect can be achieved.
