Description

Technical Field

[0001] Embodiments of the present invention relate to an attachment structure.

Background Art

[0002] In the method of installing a device, in addition to the method of placing it on an upward-facing plane, there are methods such as hooking it on a vertical surface such as a wall surface (for example, Patent Document 1). In this method, the downward force exerted by gravity on the device (equivalent to the weight of the device) is utilized.

[0003] In the case of the attachment structure as described above, when an "upward force" that cancels out the above-mentioned "downward force" is applied to the device, the device may move upward and the hooked and held state may be impaired, and inconveniences such as the device falling may occur. The cause of the upward force is the rigidity of the cable arranged between the device and the floor. For example, when a cable with high rigidity is connected to a device hooked on a wall surface, a force in the upward push direction may be applied to the device from the cable touching the floor.

[0004] Among the attachment methods using the Daruma hole introduced in Patent Document 1, there are those that are not simple one-way hooks, such as those in Patent Documents 2 and 3, but none of them are suitable for the use of attaching a device such as a housing of a device, which is difficult to utilize elasticity, to a wall surface.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The problem to be solved by the present invention is to provide a structure that is easily detachable while being less likely to accidentally fall off when attaching a device to a vertical surface.

Means for Solving the Problems

[0006] The mounting structure of the embodiment is a mounting structure for attaching and supporting an object to be supported to a support portion, including a convex portion protruding from a surface, and a recess or a through-hole-shaped concave portion into which the convex portion fits. One of them is provided at a plurality of locations on the support portion, and the other is provided at a plurality of locations on the object to be supported. The plurality of first shapes, which are the convex portions or the concave portions provided on the object to be supported, are located on the outer peripheral portion of the object to be supported, and the central portion of the object to be supported is positioned between the first shapes other than itself. The second shape, which is the concave portion or the convex portion provided on the support portion, is located at a position corresponding to the first shape. The convex portion has a constriction between its base and tip. The concave portion has a length that allows movement of the convex portion within a predetermined range when the object to be supported is rotated about the normal line of the surface with respect to the support portion. The width of the hooking portion, which is one end in the length direction, is equal to or greater than the thickness of the constriction and less than the thickness of the tip portion, and the width of the insertion / extraction portion, which is the other end, is equal to or greater than the thickness of the tip portion.

Embodiments for Carrying Out the Invention

[0008] (First Embodiment) An embodiment will be described with reference to the drawings. FIG. 1 is a perspective view showing an example of the mounting structure of this embodiment. The mounting structure includes convex portions 11, 12, and 13 and concave portions 31, 32, and 33.

[0009] The convex portions 11 to 13 are an example of a first shape provided on the object to be supported, and protrude from the back surface 101 of the electronic device 10. The electronic device 10 is an example of the object to be supported. A cable 20 is connected to the lower surface 102 (see FIG. 3) of the electronic device 10 and hangs down.

[0010] The concave portions 31 to 33 are an example of a second shape provided on the support portion 30, and are through-holes formed in the support portion 30 into which the convex portions 11 to 13 are fitted. The support portion 30 is, for example, a sheet metal attached to a wall surface, a housing of a large device, or a partition wall partitioning the inside thereof.

[0011] In this embodiment, the convex portions 11 to 13 are provided on the object to be supported (electronic device 10), and the concave portions 31 to 33 are provided on the support portion 30. However, in practice, it is not limited to this, and the reverse may be true. That is, the convex portions 11 to 13 may be provided on the support portion 30, and the concave portions 31 to 33 may be provided on the object to be supported (electronic device 10). Also, in this case, the concave portions 31 to 33 are an example of the first shape, and the convex portions 11 to 13 are an example of the second shape.

[0012] The electronic device 10 is, for example, an information processing device such as a PC (Personal Computer). The electronic device 10 generally has a box-shaped housing, and its center of gravity is often located closer to the central portion than the outer peripheral portion.

[0013] The convex portions 11 to 13 are located on the outer peripheral portion of the electronic device 10. That is, they are provided at positions close to the contour on the back surface 101 where the convex portions 11 to 13 of this embodiment are provided.

[0014] Further, the convex portions 11 position the central portion of the electronic device 10 between themselves and the other convex portions 12 and 13. Similarly, the convex portion 12 positions the central portion of the electronic device 10 between itself and the other convex portions 13 and 11. That is, the convex portions 11 to 13 are arranged so as to surround the central portion of the electronic device 10. For example, the convex portions 11 to 13 are not arranged so as to be biased only to one side (left or right) of the electronic device 10.

[0015] With the above-described arrangement, the convex portions 11 to 13 are positioned surrounding the center of gravity of the electronic device 10.

[0016] The convex portions 11 to 13 have a constriction between the base and the tip. More specifically, the base is the portion connected to the back surface 101, and the constriction is the portion having a smaller diameter than the tip. Note that the shape of the convex portions 11 to 13 may be such that a part of the portion up to the base excluding the tip is formed with a small diameter, or alternatively, only the tip is formed with a large diameter.

[0017] The concave portions 31 to 33 have a length that allows the movement of the convex portions 11 to 13 within a predetermined range when the electronic device 10 is rotated about the normal line of the back surface 101 with respect to the support portion 30. Thereby, the electronic device 10 is rotatable within a predetermined range with respect to the support portion 30.

[0018] In order to realize the above-described positional relationship in the concave portions 31 to 33, for example, the longitudinal direction of the concave portions 31 to 33 draws an arc centered on a point located between them (the concave portions 31 to 33), or has a shape close thereto.

[0019] The recesses 31 to 33 are shaped such that the width at one end in the length direction is narrow and the width at the other end is wide. More specifically, the width at one end in the length direction of the recesses 31 to 33 is equal to or greater than the constriction thickness of the protrusions 11 to 13 and less than the thickness of the tip portions of the protrusions 11 to 13. Also, the width at the other end in the length direction of the recesses 31 to 33 is equal to or greater than the thickness of the tip portions of the protrusions 11 to 13. Thereby, the protrusions 11 to 13 can be inserted and removed from the other ends of the recesses 31 to 33, and are hooked and held at one end and cannot be inserted and removed. Hereinafter, the one end (the narrower side) of the recesses 31 to 33 is referred to as the hooking portion, and the other end (the wider side) is referred to as the insertion / removal portion.

[0020] Note that the recesses 31 to 33 as described above are generally called "Daruma holes" or "KeyHoles". Also, the shape of the recesses 31 to 33 is also called a gourd shape or a KeyHole shape.

[0021] FIG. 2 is a diagram showing an example of how an object to be supported (electronic device 10) is attached to the support portion 30. When attaching, the operator first inserts the protrusions 11, 12, 13 of the electronic device 1 into the insertion / removal portions of the recesses 31, 32, 33 as shown in FIG. 2(a). Subsequently, the operator rotates the electronic device 10 counterclockwise in the figure with respect to the support portion 30 as shown in FIG. 2(b). Thereby, the protrusions 11 to 13 move within the recesses 31 to 33 and reach the hooking portion as shown in FIG. 2(c).

[0022] The recesses 31 to 33 are provided such that when the constrictions of the protrusions 11 to 13 reach the hooking portion, the electronic device 10 assumes a predetermined attached state with respect to the support portion 30. For example, the state in FIG. 2(c) is an example of a predetermined attached state, and the rectangular parallelepiped-shaped electronic device 10 is attached to the substantially rectangular support portion 30 without tilting.

[0023] Note that when removing the electronic device 10 from the support portion 30, the electronic device 10 is rotated in the opposite direction to the above description.

[0024] Next, with reference to FIGS. 3 and 4, an example of an arrangement in which the direction from the engaging portion to the insertion / removal portion in at least any one of the plurality of recesses 31 to 33 does not match the direction in which an external force (the force applied to the cable 20) constantly applied to the electronic device 10 attempts to rotate the electronic device 10 will be described.

[0025] FIG. 3 is a diagram for explaining the influence of the gravitational force applied to the supported object (electronic device 10) on the mounting structure. In this example, the electronic device 10 is subjected to a downward tensile load due to the gravitational force applied to the cable 20.

[0026] In this case, among the three recesses 31 to 33, the lower end portion of the recess 31 whose longitudinal direction is vertical is the engaging portion. Therefore, a force acts to rotate the electronic device 10 in the clockwise direction in the figure around the convex portion 11 supported by this engaging portion.

[0027] However, the direction from the engaging portion to the insertion / removal portion of the other recess 32 is diagonally upward to the right in the figure and does not follow the direction A (diagonally downward to the right) in which the above-described force acts. Therefore, the convex portion 12 does not move within the recess 32. Thus, the electronic device 10 does not rotate, and the predetermined mounted state is maintained.

[0028] FIG. 4 is a diagram for explaining the influence of the upward pushing force applied to the supported object (electronic device 10) on the mounting structure. In the example shown in this figure, the electronic device 10 is given an upward pushing force from the cable 20.

[0029] In this case, among the three recesses 31 to 33, the upper end portion of the recess 33 is the engaging portion. Therefore, a force acts to rotate the electronic device 10 in the clockwise direction in the figure around the convex portion 13 supported by this engaging portion.

[0030] However, since the direction from the engaging portion to the insertion / removal portion of the other recess 32 does not follow the direction B of the force that attempts to rotate the electronic device 10 described above, the convex portion 12 does not move within the recess 32. Thus, the electronic device 10 does not rotate, and the predetermined mounted state is maintained.

[0031] As described above, according to the present embodiment, any one of the plurality of recesses 31 to 33 serves as a pivot point of rotation, and the others except for that serve as a function of preventing rotation. Therefore, the rotation of the electronic device 10 is blocked, and a predetermined attachment state to the support portion 30 is maintained. As a result, the electronic device 10 can be stably fixed. In addition, since it is a structure that is attached and detached by rotation, tools are not required for attachment and detachment.

[0032] Therefore, according to the present embodiment, when attaching the electronic device 10 to a vertical surface, it is possible to provide a structure that is easily detachable while being less likely to accidentally fall off.

[0033] In the present embodiment, three combinations of protrusions and recesses are provided. However, in practice, at least two or more combinations are provided. However, if there are two, there may be a concern about the mounting strength depending on the arrangement and structure. If there are four or more, the alignment work during mounting becomes more troublesome, and the cost of dimension tolerance adjustment during manufacturing increases. For this reason, it is preferable that the number of locations where the combination of the protrusion and the recess is provided is three.

[0034] The above-described embodiment can also be appropriately modified and implemented by changing a part of the configuration or function of each of the above-described devices. Hereinafter, a modified example according to the above-described embodiment will be described. Hereinafter, the points different from the above-described embodiment will be mainly described, and the same reference numerals will be used for the points common to the already described content, and the detailed description will be omitted. In addition, each of the elements included in the above-described embodiment and the following modified examples may be implemented individually or in appropriate combination.

[0035] (Modified Example) With reference to FIG. 5, a case will be described in which, when there is an external force constantly applied to the side surface of the electronic device 10, the direction from the insertion portion to the hook portion in at least any one of the plurality of recesses 31 to 33 is opposite to the direction in which the external force attempts to rotate the electronic device 10.

[0036] FIG. 5 is a perspective view showing a modified example of the mounting structure. In this modified example, a case where the electronic device 10, which was vertically (longitudinally) mounted on the support portion 30 in the above-described embodiment, is mounted horizontally (transversely) will be described. Note that there is no change in the support portion 30 of this modified example, and it is the same as that of the above-described embodiment.

[0037] The cable 20 is connected to the side surface 103 of the electronic device 10. Here, the side surface 103 is the same surface as the lower surface 102 in the above-described embodiment.

[0038] The cable 20 is bent and hanging down. The bent portion 21 of the cable 20 is illustrated by reference numeral 61.

[0039] FIG. 6 is a diagram showing an example of a method of attaching the object to be supported (electronic device 10) to the support portion 30. When attaching, the operator first inserts the convex portions 13, 11, and 12 of the electronic device 1 into the insertion portions of the concave portions 31, 32, and 33 as shown in FIG. 6(a). Subsequently, as shown in FIG. 6(b), the operator rotates the electronic device 10 counterclockwise in the drawing with respect to the support portion 30. As a result, the convex portions 13, 11, and 12 move within the concave portions 31, 32, and 33 and reach the engaging portions as shown in FIG. 6(c).

[0040] The concave portions 31, 32, and 33 are provided such that the electronic device 10 is in a predetermined mounted state with respect to the support portion 30 when the constriction of the convex portions 13, 11, and 12 reaches the engaging portion. For example, the state shown in FIG. 6(c) is an example of a predetermined mounted state, and the rectangular parallelepiped-shaped electronic device 10 is mounted on the substantially rectangular support portion 30 without tilting.

[0041] When removing the electronic device 10 from the support portion 30, the electronic device 10 is rotated in the reverse direction to the above description.

[0042] FIG. 7 is a diagram for explaining the influence of the gravitational force applied to the object to be supported (electronic device 10) on the mounting structure. In the case shown in this figure, the electronic device 10 is applied with a downward tensile load due to the gravitational force applied to the cable 20 on the side surface 103.

[0043] In this case, among the three recesses 31 to 33, since the lower end of the recess 31 with its longitudinal direction facing up and down serves as the engaging portion, a force acts to rotate the electronic device 10 counterclockwise in the figure about the convex portion 13 supported by this engaging portion.

[0044] However, the direction from the engaging portion to the insertion / extraction portion of the other recess 32 slopes upward to the upper right in the figure and does not follow the direction C (leftward) in which the above-described force acts. Therefore, the convex portion 11 does not move within the recess 32. Also, the direction from the engaging portion to the insertion / extraction portion of the recess 33 is opposite to the direction D in which the above-described force acts. Therefore, the convex portion 12 does not move within the recess 33. Thus, the electronic device 10 does not rotate, and the predetermined mounted state is maintained.

[0045] Here, in this modification, when a load in the upward direction from bottom to top is applied to the cable 20, since the cable 20 has the bent portion 21, most of the above-described load is consumed as a force that increases the bending of the cable 20 rather than the rotation of the electronic device 10. Therefore, the possibility that an upward load is transmitted from the cable 20 to the electronic device 10 and the electronic device 10 rotates clockwise in the figure and drops off from the support portion 30 is low.

[0046] Note that when the connection position of the cable 20 is located on the side surface of the electronic device 10, it is necessary to ensure that the direction of the force when pulled downward from the mounting position does not coincide with the rotation direction during removal. For example, in the case of FIG. 7, the cable 20 is connected to the left side surface 103 in the figure. However, if the cable 20 were connected to the right side surface 104 in the figure, a force would act to rotate the electronic device 10 clockwise in the figure due to the pulling force applied to the cable 20. In this case, there is a possibility that the electronic device 10 rotates clockwise in the figure and drops off from the support portion 30.

[0047] Although some embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, changes, and combinations can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalent scope thereof.
