Description

Technical Field

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

Background Art

[0002] Regarding the installation method of a device, in addition to the method of placing it on an upward 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 (equivalent to the weight of the device) exerted by gravity on 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, resulting in inconveniences such as the device falling. 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 pushing 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 attaching something like the 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 difficult to accidentally fall off when attaching a device to a vertical surface.

Means for Solving the Problems

[0006] The attachment structure of the embodiment is an attachment structure for attaching and supporting a supported object to a support portion, The object to be supported is attached to the support portion and is oriented vertically.The support portion is provided with a convex portion that protrudes from a surface and a recess or through-hole-shaped recess into which the convex portion fits, and the other of these is provided at multiple locations on the supported object. The multiple first shapes, which are the convex portions or recesses provided on the supported object, are located on the outer circumference of the supported object, positioning the central part of the supported object between itself and the other first shapes. The second shapes, which are the recesses or convex portions provided on the support portion, are located at positions corresponding to the first shapes. The convex portion has a constriction between its base and tip. The recess has a length that allows the convex portion to move within a predetermined range when the supported object is rotated relative to the support portion around the normal to the surface as an axis. The width of the hook portion, which is one end in the longitudinal direction, is greater than or equal to the thickness of the constriction and less than the thickness of the tip. The width of the insertion / removal portion, which is the other end, is greater than or equal to the thickness of the tip. the law of nature , When an external force applied to the supported object supported by the support portion acts in a direction that causes the supported object to rotate, one of the multiple protrusions functions as the center of rotation, and the direction in which at least one of the other protrusions attempts to move by the rotation relative to the hook portion that supports it does not coincide with the direction from the hook portion that supports it toward the insertion / removal portion. .

[0008] (First Embodiment) Embodiments will be described with reference to the drawings. Figure 1 is a perspective view showing an example of the mounting structure of this embodiment. The mounting structure consists of protrusions 11, 12, 13 and recesses 31, 32, 33.

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

[0010] The recesses 31-33 are examples of a second shape provided in the support portion 30, and are through holes formed in the support portion 30 into which the protrusions 11-13 fit. The support portion 30 is, for example, a sheet metal attached to a wall, the housing of a large piece of equipment, or a partition wall that divides the inside thereof.

[0011] In this embodiment, the protrusions 11-13 are provided on the supported object (electronic device 10) and the recesses 31-33 are provided on the support portion 30. However, the implementation is not limited to this arrangement, and the reverse is also possible. In other words, the protrusions 11-13 may be provided on the support portion 30 and the recesses 31-33 may be provided on the supported object (electronic device 10). In this case, the recesses 31-33 are an example of the first shape, and the protrusions 11-13 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 casing, and its center of gravity is often located closer to the center than to the outer edge.

[0013] The protrusions 11-13 are located on the outer periphery of the electronic device 10. In other words, they are located close to the contour of the back surface 101 on which the protrusions 11-13 of this embodiment are provided.

[0014] Furthermore, the protrusion 11 positions the central part of the electronic device 10 between itself and the other protrusions 12 and 13. Similarly, the protrusion 12 positions the central part of the electronic device 10 between itself and the other protrusions 13 and 11. In other words, the protrusions 11 to 13 are arranged to surround the central part of the electronic device 10, and are not arranged in such a way that, for example, the protrusions 11 to 13 are biased to only one side of the electronic device 10.

[0015] With the arrangement described above, the protrusions 11 to 13 are positioned around the center of gravity of the electronic device 10.

[0016] The protrusions 11-13 have a constriction between their base and tip. More specifically, the base is the part connected to the back surface 101, and the constriction is the part with a smaller diameter compared to the tip. The shape of the protrusions 11-13 may be such that, for example, a portion of the part from the base to the tip is formed with a smaller diameter, or only the tip is formed with a larger diameter.

[0017] The recesses 31 to 33 have a length that allows the movement of the protrusions 11 to 13 within a predetermined range when the electronic device 10 is rotated relative to the support portion 30 around the normal to the back surface 101. As a result, the electronic device 10 is rotatable within a predetermined range relative to the support portion 30.

[0018] In order to achieve the positional relationship described above for recesses 31 to 33, for example, the longitudinal direction of recesses 31 to 33 is such that it forms an arc centered on a point located between them, or a shape close to it.

[0019] The concave portions 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 concave portions 31 to 33 is not less than the thickness of the constriction of the convex portions 11 to 13 and less than the thickness of the tip portions of the convex portions 11 to 13. Also, the width at the other end in the length direction of the concave portions 31 to 33 is not less than the thickness of the tip portions of the convex portions 11 to 13. Thereby, the convex portions 11 to 13 can be inserted and removed from the other end of the concave portions 31 to 33, and are hooked and held at one end and cannot be inserted and removed. Hereinafter, the above-mentioned one end (the narrower side in width) of the concave portions 31 to 33 is referred to as the hooking portion, and the other end (the wider side in width) is referred to as the insertion / removal portion.

[0020] Note that the concave portions 31 to 33 as described above are generally called "Daruma holes" or "KeyHoles". Also, the shape of the concave portions 31 to 33 is also called a gourd shape or a KeyHole (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 convex portions 11, 12, 13 of the electronic device 1 into the insertion / removal portions of the concave portions 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 convex portions 11 to 13 move within the concave portions 31 to 33 and reach the hooking portion as shown in FIG. 2(c).

[0022] The concave portions 31 to 33 are provided such that when the constriction of the convex portions 11 to 13 reaches the hooking portion, the electronic device 10 is in 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 reverse direction to the above description.

[0024] Next, Figures 3 and 4 illustrate an example of an arrangement in which the orientation from the hooking portion to the insertion / removal portion in at least one of the multiple recesses 31 to 33 does not coincide with the orientation in which the external force constantly applied to the electronic device 10 (force on the cable 20) attempts to rotate the electronic device 10.

[0025] Figure 3 illustrates the effect of the tensile force acting on 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 tensile force acting on the cable 20.

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

[0027] However, the orientation of the other recess 32 from the hooking portion to the insertion / removal portion is upward to the right in the figure, and does not align with the direction A (downward to the right) in which the aforementioned force acts. Therefore, the protrusion 12 does not move within the recess 32. Thus, the electronic device 10 does not rotate, and the predetermined mounting state is maintained.

[0028] Figure 4 illustrates the effect of the upward force acting on the supported object (electronic device 10) on the mounting structure. In the example shown in this figure, the electronic device 10 is subjected to an upward force from the cable 20.

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

[0030] However, since the orientation of the other recess 32 from the hooking portion to the insertion / removal portion does not align with the direction B of the force that attempts to rotate the electronic device 10, the protrusion 12 does not move within the recess 32. Therefore, the electronic device 10 does not rotate, and the predetermined mounting state is maintained.

[0031] As described above, according to this embodiment, one of the multiple recesses 31 to 33 acts as a pivot point for rotation, while the others function to prevent rotation. As a result, the rotation of the electronic device 10 is prevented, and a predetermined mounting state to the support part 30 is maintained. This makes it possible to stably fix the electronic device 10. Furthermore, since it is designed to be attached and detached by rotating, no tools are required for attachment and detachment.

[0032] Therefore, according to this embodiment, when attaching the electronic device 10 to a vertical surface, it is possible to provide a structure that is easy to attach and detach, while being less prone to unintended detachment.

[0033] In this embodiment, the combination of a protrusion and a recess is provided in three locations, but in actual implementation, at least two or more locations should be provided. However, with only two locations, there may be concerns about mounting strength depending on the arrangement and structure, and with four or more locations, the effort required for alignment during installation increases, as does the cost of adjusting dimensional tolerances during manufacturing. For this reason, it is preferable to have three locations where the combination of a protrusion and a recess is provided.

[0034] The embodiments described above can also be modified and implemented as appropriate by changing some of the configurations or functions of each of the devices described above. Below, modifications of the embodiments described above will be explained. Below, we will mainly explain the differences from the embodiments described above, and the same reference numerals will be used for parts that are common to those already described, and detailed explanations will be omitted. Furthermore, each element of the embodiments described above and the following modifications may be implemented individually or in combination as appropriate.

[0035] (modified version) Figure 5 illustrates an example in which, when an external force is constantly applied to the side surface of the electronic device 10, the orientation from the insertion / removal portion to the hooking portion in at least one of the multiple recesses 31 to 33 is set to the opposite direction to the direction in which the external force attempts to rotate the electronic device 10.

[0036] Figure 5 is a perspective view showing a modified mounting structure. In this modified example, the case in which the electronic device 10, which was mounted vertically (vertically oriented) to the support part 30 in the above embodiment, is mounted horizontally (horizontally oriented) will be described. Note that the support part 30 in this modified example remains unchanged and is the same as in the above embodiment.

[0037] The electronic device 10 has a cable 20 connected to its side surface 103. Here, side surface 103 is the same surface as the bottom surface 102 in the above embodiment.

[0038] Cable 20 is bent and hanging down. Reference numeral 61 indicates the bent portion 21 of cable 20.

[0039] Figure 6 shows an example of how to attach the object to be supported (electronic device 10) to the support part 30. When attaching, the operator first inserts the protrusions 13, 11, and 12 of the electronic device 1 into the insertion / removal parts of the recesses 31, 32, and 33, as shown in Figure 6(a). Next, the operator rotates the electronic device 10 in a counterclockwise direction relative to the support part 30, as shown in Figure 6(b). As a result, the protrusions 13, 11, and 12 move within the recesses 31, 32, and 33 and reach the hooking part, as shown in Figure 6(c).

[0040] The recesses 31, 32, and 33 are provided so that the electronic device 10 is in a predetermined mounting state to the support part 30 when the constrictions of the protrusions 13, 11, and 12 reach the hook portion. For example, the state shown in Figure 6(c) is an example of a predetermined mounting state, in which the rectangular parallelepiped electronic device 10 is mounted to the substantially rectangular support part 30 without tilting.

[0041] When removing the electronic device 10 from the support part 30, rotate the electronic device 10 in the opposite direction to that described above.

[0042] Figure 7 illustrates the effect of the tensile force acting on the supported object (electronic device 10) on the mounting structure. In the example shown in this figure, the electronic device 10 is subjected to a downward tensile load on its side surface 103 due to the tensile force acting on the cable 20.

[0043] In this case, of the three recesses 31 to 33, the lower end of recess 31, whose longitudinal direction is oriented vertically, is the hook portion. Therefore, a force acts to rotate the electronic device 10 in a counterclockwise direction in the figure, around the convex portion 13 supported by this hook portion.

[0044] However, the orientation of the other recess 32 from the hooking portion to the insertion / removal portion is upward sloping to the right in the figure, and does not align with the direction C (leftward) in which the aforementioned force acts, so the protrusion 11 does not move within the recess 32. Also, the orientation of the recess 33 from the hooking portion to the insertion / removal portion is opposite to the direction D in which the aforementioned force acts, so the protrusion 12 does not move within the recess 33. Therefore, the electronic device 10 does not rotate, and the predetermined mounting state is maintained.

[0045] In this modified example, if a load is applied to the cable 20 in an upward direction, since there is a bend 21 in the cable 20, the load is consumed more as a force increasing the bending of the cable 20 than as a force causing the electronic device 10 to rotate. Therefore, it is unlikely that an upward load will be transmitted from the cable 20 to the electronic device 10, causing the electronic device 10 to rotate clockwise in the figure and fall off the support part 30.

[0046] Furthermore, if the connection point of the cable 20 is located on the side of the electronic device 10, it is necessary to ensure that the direction of the force exerted when pulling downwards from the mounting position does not coincide with the direction of rotation when detached. For example, in Figure 7, the cable 20 is connected to the left side 103 in the figure, but if the cable 20 were connected to the right side 104 in the figure, the attractive force acting on the cable 20 would cause a force to rotate the electronic device 10 clockwise in the figure. In this case, there is a possibility that the electronic device 10 will rotate clockwise in the figure and detach from the support part 30.

[0047] While several embodiments of the present invention have been described, these embodiments are presented as examples only and are not intended to limit the scope of the invention. These novel embodiments can be carried out in a variety of other forms, and various omissions, substitutions, modifications, and combinations are possible without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention, as well as in the claims of the invention and its equivalents. [Explanation of Symbols]
