Description

Technical Field

[0001] The present invention relates to a mounting device, and more specifically, to a mounting device that can be attached to a testing machine for performing an accelerated degradation test.

Background Art

[0002] An accelerated degradation test is a test for grasping the degradation characteristics of a test specimen in a relatively short period by adjusting weather factors and air pollution factors that degrade the test specimen to accelerate the degradation of the test specimen. In an accelerated degradation test, for example, a weather resistance test in which a test specimen is irradiated with light by an artificial light source to test the weather resistance of the test specimen, a water resistance test in which water is sprayed onto the test specimen to test the water resistance of the test specimen, or a combination thereof is performed. As a testing machine capable of performing such an accelerated degradation test (hereinafter referred to as an "accelerated degradation testing machine"), for example, a testing machine described in Patent Document 1 is known.

Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, as an example of the test specimen, a sealing material used in construction or the like can be mentioned. Such a sealing material is provided, for example, at the joint between exterior materials constituting the wall surface of a house or the like. Such a sealing material is compressed due to the expansion of the exterior material at high temperatures and pulled due to the contraction of the exterior material at low temperatures. Therefore, for example, when the sealing material is used as the test specimen, in an accelerated degradation test, it may be required to apply compression and tension to the test specimen (hereinafter, the compression and tension of the test specimen are collectively referred to as "movement").

[0005] <000The present invention has been made in view of the above points, and one example of its objective is to provide a mounting device that can impart movement to a test subject in an accelerated degradation test. [Means for solving the problem]

[Effects of the Invention]

[0013] According to the present invention, it is possible to provide a mounting device that can impart movement to a test subject in an accelerated degradation test. [Brief explanation of the drawing]

[0014] [Figure 1] This figure schematically shows a part of the internal structure of an accelerated degradation testing machine to which the mounting device according to an embodiment of the present invention is attached. [Figure 2] This is a front view showing an embodiment of the mounting device according to the present invention, and is a transparent view of the cover body of the mounting device. [Figure 3] Figure 2 is a side view showing the mounting device, specifically a transparent view of the cover body of the mounting device. [Figure 4] Figures 2 and 3 are bottom views showing only the cover body. [Modes for carrying out the invention]

[0015] The following examples illustrate embodiments for implementing the mounting device according to the present invention, along with the accompanying drawings. The embodiments illustrated below are provided to facilitate understanding of the present invention and are not intended to limit its interpretation. The present invention can be modified and improved from the following embodiments without departing from its spirit. In addition, in the accompanying drawings, the dimensions of each component may be exaggerated or reduced, or hatching may be omitted, in order to facilitate understanding.

[0016] Figure 1 is a schematic diagram showing a part of the internal structure of an accelerated degradation testing machine according to an embodiment. As shown in Figure 1, the accelerated degradation testing machine 100 according to an embodiment comprises a test chamber 101 in which an accelerated degradation test is performed, a subject holder 102 for holding a subject to be subjected to the accelerated degradation test, a light source 103, and a sprayer 104. The subject holder 102, the light source 103, and the sprayer 104 are housed inside the test chamber 101.

[0017] The light source 103 may be, for example, positioned in the center of the space inside the test chamber 101, or it may be one or more rod-shaped light sources extending along the first direction X. In the accelerated degradation test machine 100 according to this embodiment, the first direction X is the vertical direction. This is not limited to certain applications and may vary depending on the intended use and installation method of the accelerated degradation testing machine.

[0018] The light source 103 can be changed as appropriate depending on the type of accelerated degradation test, and may be a xenon lamp, a metering lamp, a sunshine carbon arc, or an ultraviolet carbon arc, for example. The light source 103 emits light in a second direction Y (for example, the radial direction of the test chamber 101) perpendicular to the first direction X, passing through the light source 103. Here, in the second direction Y, the side relatively closer to the light source 103 is described as "inside," and the side relatively farther from the light source 103 is described as "outside."

[0019] The sprayer 104 extends, for example, in the first direction X and can spray water, for example, in a mist form, toward the outside in the second direction Y.

[0020] The specimen holder 102 may be a plate-like portion extending in the first direction X. The specimen holder 102 may be arranged, for example, near the wall surface of the test tank 101. The specimen holder 102 faces the light source 103 and the sprayer 104 in the second direction Y. The specimen may be held on the inner surface 102A of the specimen holder 102. That is, the specimen held on the inner surface 102A of the specimen holder 102 is arranged to face the light source 103 and the sprayer 104 in the second direction Y. Then, the inner surface of this specimen is exposed to the light emitted from the light source 103 and the water sprayed from the sprayer 104, thereby accelerating the deterioration of the specimen. Note that the specimen holder 102 may be configured to be rotatable around the light source 103 by a mechanism not shown.

[0021] An attachment device 1 is attached to the specimen holder 102. That is, the attachment device 1 is a device that can be attached to an existing accelerated deterioration tester. The entire attachment device 1 is housed inside the test tank 101. In the present embodiment, the attachment device 1 attached to the specimen holder 102 extends in the first direction X and faces the light source 103 and the sprayer 104 in the second direction Y. The attachment device 1 includes a cover body 10 and a jig 20 exposed from the lower portion of the cover body 10.

[0022] In the accelerated degradation tester 100 to which the mounting device 1 is attached, the test subject Sa is held by the jig 20 of the mounting device 1. The inner surface SaF of the test subject Sa held by the jig 20 in the second direction Y faces the light source 103 and the sprayer 104 (without any obstruction) in the second direction Y. That is, surface SaF faces the light source 103 and the sprayer 104 through space. Therefore, in this embodiment, surface SaF of the test subject Sa is exposed to light emitted from the light source 103 and water sprayed from the sprayer 104, and as a result, the degradation of the test subject Sa is accelerated. Hereafter, surface SaF of the test subject Sa may be referred to as the "exposed surface SaF".

[0023] Next, the mounting device 1 will be described in more detail. Figure 2 is a front view of the mounting device 1 (viewed from the inside outward in the second direction Y), showing the cover body 10 through a transparent view. Figure 3 is a side view of the mounting device 1 (viewed from the third direction Z perpendicular to the first direction X and the second direction Y), showing the cover body 10 through a transparent view. Figure 4 is a bottom view showing only the cover body 10 (viewed from below in the first direction X).

[0024] As shown in Figures 2 to 4, the mounting device 1 comprises the cover body 10 described above, the jig 20 described above, the movement-granting mechanism 30, one or more mounting parts 40, a base plate 50, and an elastic member 60.

[0025] The cover body 10 includes the cover body main body 11 and the flange portion 12.

[0026] The cover body 11 includes a first surface 11A that is rectangular or square when viewed from the out-of-plane direction. The first surface 11A is the surface that faces inward in the second direction Y when the cover body 10 is attached to the specimen holder 102 of the accelerated degradation tester 100.

[0027] Furthermore, the cover body 11 includes four surfaces (second surface 11B, third surface 11C, fourth surface 11D, and fifth surface 11E) that extend out of the plane of the first surface 11A from each of the four ends (edges) of the first surface 11A.

[0028] The second surface 11B has a rectangular shape and, when the cover body 10 is attached to the specimen holder 102, is located on the upper side in the first direction X (vertical direction) and extends outward in the second direction Y from the upper end (upper edge) of the first surface 11A.

[0029] The third surface 11C has a rectangular shape and, when the cover body 10 is attached to the specimen holder 102, is located on the lower side in the first direction X (vertical direction) and extends outward in the second direction Y from the lower end (lower edge) of the first surface 11A. When the cover body 10 is attached to the specimen holder 102, a notch 11CR is formed in the central part of the third surface 11C in the third direction Z and on the outer side in the second direction Y. The shape of the notch 11CR is not particularly limited, but in this embodiment it is rectangular.

[0030] The fourth surface 11D has a rectangular shape and, when the cover body 10 is attached to the subject holder 102, is located on one side in the third direction Z, extending outward in the second direction Y from one end (edge) of the first surface 11A in the third direction Z. The upper end (edge) of the fourth surface 11D is connected to one end (edge) of the second surface 11B in the third direction Z, and the lower end (edge) of the fourth surface is connected to one end (edge) of the third surface 11C in the third direction Z.

[0031] The fifth surface 11E has a rectangular shape and, when the cover body 10 is attached to the subject holder 102, is located on the other side in the third direction Z, extending outward in the second direction Y from the other end (edge) of the first surface 11A in the third direction Z. The upper end (edge) of the fifth surface 11E is connected to the other end (edge) of the second surface 11B in the third direction Z, and the lower end (edge) of the fifth surface 11E is connected to the other end (edge) of the third surface 11C in the third direction Z.

[0032] The outer surface of the cover body 11 is open and has no surface. Therefore, the first surface 11A, second surface 11B, third surface 11C, fourth surface 11D, and fifth surface 11E of the cover body 11 form a space SR with an opening OP on the outside.

[0033] The flange portion 12 is connected to the outer end of the cover body 11 in the second direction Y and protrudes on the side opposite to the space SR formed by the cover body 11. Specifically, the flange portion 12 includes a first portion 12B that protrudes upward in the first direction X from the outer end (edge) of the second surface 11B in the second direction Y, a second portion 12D that protrudes to one side in the third direction Z from the outer end (edge) of the fourth surface 11D in the second direction Y, and a third portion 12E that protrudes to the other side in the third direction Z from the outer end (edge) of the fifth surface 11E in the second direction Y. In this embodiment, the outer end (edge) of the third surface 11C in the second direction Y is not provided with a portion constituting the flange portion 12, but for example, a portion that protrudes downward in the first direction X from the outer end (edge) of the third surface 11C in the second direction Y may be provided on the third surface 11C.

[0034] An elastic member 60 is attached to the outer surface 12F of the flange portion 12 in the second direction Y. In other words, in the direction (second direction Y) that intersects the direction in which the flange portion 12 protrudes from the cover body 11 (the direction opposite to the space SR side), an elastic member 60 is provided on the surface 12F of the flange portion 12 opposite to the side (inside) of the cover body 11 (outside). The elastic member 60 may be made of rubber, for example. In addition, a plurality of through holes 12H are formed at predetermined locations on the flange portion 12 and the elastic member 60, penetrating the flange portion 12 and the elastic member 60 in the second direction Y. For example, as shown in Figure 2, the through holes 12H may be formed at the four corners of the flange portion 12 and the elastic member 60, and near the center of each side of the flange portion 12 and the elastic member 60.

[0035] Note that attaching the elastic member 60 is not mandatory.

[0036] The base plate 50 is a plate-shaped member having a larger outer shape than the cover body 10 when viewed from the out-of-plane direction. As shown in Figure 3, the base plate 50 has a plurality of holes 50H that communicate with each of the through holes 12H described above. The cover body 10 is placed on top of the base plate 50 so that the through holes 12H communicate with the holes 50H. The base plate 50 may be fixed (for example, screwed) to the flange portion 12 of the cover body 10 via the elastic member 60 by inserting fasteners 70 into the mutually communicating through holes 12H and holes 50H. In this way, the opening OP of the cover body 10 is covered by the base plate 50. As a result, the mounting device 1 has a space SR formed in it that is surrounded by the base plate 50 and each surface of the cover body 11 (first surface 11A, second surface 11B, third surface 11C, fourth surface 11D, and fifth surface 11E). When the cover body 10 is attached to the base plate 50, one end of the base plate 50 in the first direction X and its vicinity (hereinafter referred to as the "exposed portion 50A") are not covered by the cover body 10.

[0037] The jig 20 includes a first part 21 and a second part 22 that are spaced apart in a first direction X. When the mounting device 1 is attached to the specimen holder 102, the first part 21 is on the upper side (one side) in the first direction X (vertical direction), and the second part 22 is on the lower side (the other side). The jig 20 holds the specimen Sa by the first part 21 and the second part 22 gripping the specimen Sa.

[0038] The first part 21 of the jig 20 includes a part 21A having approximately the same cross-sectional shape and area as the notch 11CR formed on the third surface 11C of the cover body 11, and a part 21B having a larger cross-sectional shape than part 21A. The cross-sectional shapes of parts 21A and 21B refer to the cross-sectional shape with the first direction X being the out-of-plane direction. In this embodiment, part 21A has a rectangular parallelepiped shape and can enter the space SR through the notch 11CR. Hereinafter, part 21A will be referred to as the "inner part 21A". In this embodiment, part 21B has a larger rectangular parallelepiped shape than the inner part 21A. Part 21B is located outside the space SR and is below the third surface 11C when the mounting device 1 is attached to the specimen holder 102. Hereinafter, part 21B will be referred to as the "outer part 21B". The first part 21 is attached to the base plate 50 so as to be movable relative to the base plate 50 in the first direction X. As shown in Figure 3, when viewed from the third direction Z, a rectangular recess 21BR is formed on the lower side of the outer portion 21B of the first portion 21.

[0039] The second portion 22 of the jig 20 has approximately the same cross-sectional shape and area as the outer portion 21B of the first portion 21. The cross-sectional shape of the second portion 22 is defined as the shape of the cross-section with the first direction X as the out-of-plane direction. In this embodiment, the second portion 22 has the shape of a rectangular parallelepiped. One end of the second portion 22 and the outer portion 21B in the third direction Z lies on a straight line extending in the first direction X, and the other end of the second portion 22 and the outer portion 21B in the third direction Z lies on a straight line extending in the first direction X. As shown in Figure 3, when viewed from the third direction Z, a rectangular recess 22R is formed on the upper side of the second portion 22. The outer ends of section 22R and recess 21BR in the second direction Y are on a straight line extending in the first direction, and the inner ends of recess 22R and recess 21BR in the second direction Y are also on a straight line extending in the first direction. The second section 22 is fixed to the base plate 50.

[0040] The jig 20 is located outside the cover body 10, except for the inner portion 21A, and when viewed from the second direction Y, it overlaps with the exposed portion 50A of the base plate 50, except for the inner portion 21A.

[0041] In this embodiment, the subject Sa is molded into a rectangular parallelepiped shape. However, the shape into which the subject Sa is molded is not limited to a rectangular parallelepiped shape. Furthermore, the subject Sa is not particularly limited, but may be, for example, a sealing material used in construction. In this embodiment, the subject Sa is bonded to the adherend, for example, a metal plate-shaped member Sh, on both sides in the first direction X. The subject Sa is then sandwiched between the first part 21 and the second part 22, with one plate-shaped member Sh housed in the recess 21BR and fixed to the first part 21 by, for example, screws or bolts, and the other plate-shaped member Sh housed in the recess 22R and fixed to the second part 22 by, for example, screws or bolts. In this way, the subject Sa is held by the jig 20, so that the exposed surface SaF, which is the inner surface of the subject Sa in the second direction Y, is positioned in the test chamber 101 of the accelerated degradation test machine 100, facing the light source 103 and the sprayer 104 in the second direction Y (see Figure 1).

[0042] As shown in Figures 2 and 3, the one or more mounting parts 40 in this embodiment include two mounting parts 40. The two mounting parts 40 are attached to the base plate 50. Specifically, in the first direction, the two mounting parts 40 are attached to the end of the base plate 50 opposite to the exposed portion 50A, and in the third direction Z, they are attached in a position that is approximately symmetrical with respect to the center of the base plate 50. In this embodiment, each of the two mounting parts 40 has a substantially inverted U-shape when viewed from the third direction Z. Specifically, each of the two mounting parts 40 includes a first part 41, a second part 42, and a third part 43. The first part 41 is fixed to the outer surface of the base plate 50 and extends in the first direction X. In the first direction X, the end 41A of the first part 41 opposite to the jig 20 is on the opposite side of the jig 20 to the end 50U of the base plate 50 opposite to the jig 20. The second part 42 is connected to the end 41A of the first part 41 and extends outward from the end 41A along the second direction Y. The outer end of the second part 42 is connected to the end 43A of the third part 43 opposite to the jig 20 side. The third part 43 extends from the end 43A toward the jig 20 side in the first direction X. In the first direction X, the length of the third part 43 is shorter than the length of the first part 41. With this configuration of the mounting part 40, in the second direction Y, a recess 44 is formed on the side of the base plate 50 opposite to the cover body 10 side (inside) (outside), surrounded by the first part 41, the second part 42, and the third part 43.

[0043] As shown in Figure 1, the recess 44 of the mounting portion 40 corresponds to the shape of the end portion 102U of the specimen holder 102 of the accelerated degradation tester 100 in the first direction X, and the end portion 102U can be fitted into this recess 44. Therefore, the mounting device 1 is attached to the accelerated degradation tester 100 by fitting the recess 44 and the end portion 102U together. Here, since the specimen holder 102 extends in the vertical direction, the end portion 102U is the upper end portion of the specimen holder 102. Therefore, by fitting the recess 44 into the end portion 102U of the specimen holder 102, the mounting device 1 can be attached to the accelerated degradation tester 100 such that the first direction X of the mounting device 1 is vertical and the jig 20 is positioned vertically downward. In addition, in this embodiment, the two mounting portions 40 are, as described above, in the third direction Z, Since the mounting device 1 is attached in a position that is approximately symmetrical with respect to the center of the base plate 50, rattling of the mounting device 1 is suppressed when the mounting device 1 is attached to the base plate 50.

[0044] The configuration of the mounting section 40 is not limited to the above configuration, as long as the mounting device 1 can be attached to an existing accelerated degradation test. For example, the mounting section 40 may have other mechanical or structural configurations, or it may be a configuration that uses magnetic force. For example, one of the magnets and magnetic material (such as iron) may be attached to a part of the outer surface of the base plate 50, and the other of the magnets and magnetic material (such as iron) may be attached to a part of the inner surface of the specimen holder 102, or magnets may be attached to both a part of the outer surface of the base plate 50 and a part of the inner surface of the specimen holder 102.

[0045] As shown in Figures 2 and 3, the movement-generating mechanism 30 includes a motor 32, a connecting part 31, a control unit 35, a battery 34, and a sensor 33. Most of the movement-generating mechanism 30 is housed in the space SR inside the cover body 10, and the portion of the movement-generating mechanism 30 not housed in space SR is housed inside the first part 21 of the jig 20. In other words, in this embodiment, the movement-generating mechanism 30 is housed inside the cover body 10 and the jig 20, respectively.

[0046] The motor 32 is fixed to the base plate 50 and housed in the space SR inside the cover body 10. The motor 32 is not particularly limited, but for example, it may be a stepping motor.

[0047] The connecting section 31 includes a braking shaft 311, two guide shafts 312, 312, a coupling 314, and a bearing holder 315. The coupling 314 and the bearing holder 315 are housed in the space SR inside the cover body 10.

[0048] The braking shaft 311 and the two guide shafts 312, 312 extend in a first direction X. The braking shaft 311 is connected to the rotating shaft of the motor 32 via a coupling 314 and is rotatably supported by a bearing held in a bearing holder 315. Thus, the braking shaft 311 rotates around its axis as the rotating shaft of the motor 32 rotates. The braking shaft 311 is housed in the space SR inside the cover body 10, except for the tip 311T (the end opposite to the coupling 314 side in the first direction X). On the other hand, the tip 311T of the braking shaft 311 is housed inside the first part 21 of the fixture 20. In this embodiment, the tip 311T is housed inside the outer part 21B of the first part 21. The first part 21 of the fixture 20 is attached to the tip 311T of the braking shaft 311, for example, via a ball screw.

[0049] The two guide shafts 312, 312 are positioned on one side and the other side in the third direction Z relative to the braking shaft 311 and are fixed to the base plate 50. The two guide shafts 312, 312 pass through the bearing holder 315 in the first direction X, and their respective tips 312T, 312T (the end opposite to the coupling 314 side in the first direction X) are fitted inside the first part 21 of the jig 20. Meanwhile, the parts of the guide shafts 312 excluding the tips 312T are housed in the space SR inside the cover body 10.

[0050] The motor 32 and the first part 21 of the jig 20 are connected by the connecting part 31 having the above configuration. Therefore, when the motor 32 rotates, the braking shaft 311 rotates around its axis, and the first part 21 of the jig 20 moves to one side and the other side in the first direction X relative to the second part 22 of the jig 20 by the action of, for example, a ball screw provided at the tip 311T of the braking shaft 311. The two guide shafts 312, 312 guide the movement of the first part 21 in the first direction X. In this way, the connecting part 31 connects the motor 32 and the jig 20, and drives the motor 32 The jig 20 is configured to move relative to each other in the first direction X in response to the movement.

[0051] In this embodiment, since the first direction X is vertical, the first part 21 moves upward and downward relative to the second part 22. Therefore, the specimen Sa housed in the recesses 21BR and 22R of the jig 20 is compressed in the first direction X as the first part 21 descends, and pulled in the first direction X as the first part 21 rises from its lowered position. In this way, the movement-granting mechanism 30 imparts a compressive or tensile movement to the specimen Sa held in the jig 20.

[0052] Furthermore, the movement-granting mechanism 30 only needs to be configured to move the first part 21 and the second part 22 relative to each other in the first direction X. That is, the movement-granting mechanism 30 may be configured such that the first part 21 is fixed to the base plate 50 and the second part 22 moves relative to the first part 21 in the first direction X. Moreover, the configuration of the movement-granting mechanism 30 is not particularly limited as long as it can impart a compression or tension movement to the specimen Sa held in the jig 20.

[0053] The sensor 33 is housed in the space SR inside the cover body 10. The sensor 33 may be configured to detect the travel distance of the first part 21 of the jig 20 and to output a signal indicating this data to the control unit 35.

[0054] The control unit 35 is housed in the space SR inside the cover body 10 and is fixed to the base plate 50. The control unit 35 includes a control board 351, a motor driver 352, and various input units In. The control board 351 and motor driver 352 may control the drive of the motor 32 in response to signals from, for example, the sensor 33 or inputs from the various input units In.

[0055] The user of the mounting device 1 can input the operation of the movement-granting mechanism 30 by operating various input units In. For example, by operating various input units In, the user can input to the mounting device 1 (1) the speed at which the first part 21 descends from the reference position, (2) the descending position of the first part 21 relative to the reference position, (3) the stopping time of the first part 21 at the descending position, (4) the speed at which the first part 21 rises from the descending position, (5) the stopping time of the first part 21 at the reference position, and (6) the number of cycles of (1) to (5).

[0056] The battery 34 is housed in the space SR inside the cover body 10 and fixed to the base plate 50. The battery 34 supplies power to the motor 32 and the control unit 35, etc. Therefore, the mounting device 1 is supplied with power independent of the accelerated degradation test machine 100 (i.e., power from the battery 34). In other words, the mounting device 1 has a separate power supply source from the accelerated degradation test machine 100, and this power supply source is incorporated inside the mounting device 1 (in the space SR). In this embodiment, the battery 34 has heat resistance up to 50°C. The battery 34 may have heat resistance up to 50°C or higher.

[0057] As described above, the mounting device 1 is attachable to an accelerated degradation testing machine 100 that performs accelerated degradation tests. The mounting device 1 comprises a cover body 10, a jig 20 that holds a test subject Sa to be subjected to the accelerated degradation test, a movement-applying mechanism 30 that applies a compression or tension movement to the test subject Sa held in the jig 20, and a mounting part 40 that allows the mounting device 1 to be attached to the inside of the accelerated degradation testing machine 100. The movement-applying mechanism 30 is housed inside the cover body 10 and the jig 20, respectively.

[0058] The mounting device 1 is designed to be attachable inside the accelerated degradation testing machine 100. The device comprises a mounting section 40 and a movement-applying mechanism 30 that applies compression or tension to the specimen Sa held by the jig 20. Therefore, by attaching the mounting device 1 to an existing accelerated degradation testing machine 100, it becomes possible to perform accelerated degradation tests in which movement is applied to the specimen Sa.

[0059] Furthermore, with this mounting device 1, since the movement-adding mechanism 30 is housed inside the cover body 10 and the jig 20, it is possible to waterproof the movement-adding mechanism 30 when water is sprayed into the accelerated degradation testing machine 100 to perform a water resistance test on the subject Sa.

[0060] Furthermore, according to the jig 20 of the mounting device 1, the first portion 21 on one side in the first direction X and the second portion 22 on the other side in the first direction X clamp the subject Sa. Also, according to the mounting device 1, the movement mechanism 30 is configured to move the first portion 21 and the second portion 22 relative to each other in the first direction X. With this configuration, the movement mechanism 30 moves one of the first portion 21 and the second portion 22 that clamp the subject Sa in the first direction X relative to the other, so that the subject Sa can be compressed or pulled along the first direction X.

[0061] Furthermore, in the mounting device 1, the movement-granting mechanism 30 includes a motor 32, a connecting part 31 that connects the motor 32 to the jig 20 and is configured to move the first part 21 and the second part 22 of the jig 20 relative to each other in a first direction X in response to the drive of the motor 32, a control unit 35 that controls the drive of the motor 32, and a battery 34 that supplies power to the motor 32 and the control unit 35. With this configuration, when water is sprayed into the accelerated degradation tester 100 to perform a water resistance test on the test subject Sa, the motor 32, the connecting part 31, the control unit 35, and the battery 34 can be waterproofed. In addition, the battery 34 allows the mounting device 1 to be operated independently of the accelerated degradation tester 100.

[0062] Furthermore, in the mounting device 1, the battery 34 has a heat resistance of 50°C. With this configuration, for example, even if the light source 103 of the accelerated degradation tester 100 emits light to perform a weather resistance test, and the temperature inside the accelerated degradation tester 100 rises to 50°C, the battery 34 will still operate. Therefore, with the mounting device 1, even if the temperature inside the accelerated degradation tester 100 reaches 50°C, it is possible to perform an accelerated degradation test in which movement is applied to the test subject Sa.

[0063] Furthermore, in the mounting device 1, the surface of the specimen Sa held by the jig 20 in the second direction Y, which is perpendicular to the first direction X (exposed surface SaF), is exposed from the cover body 10, and the exposed surface SaF faces the light source 103 of the accelerated degradation test machine 100 in the second direction Y. With this configuration, the amount of light irradiated onto the exposed surface SaF is maximized. Therefore, the degradation of the specimen Sa can be further accelerated.

[0064] As mentioned above, the exposed surface SaF of the specimen Sa is exposed from the cover body 10. That is, at least a part of the jig 20 (the second part 22 and the outer part 21B of the first part 21) is exposed from the cover body 10 in order to expose a part of the specimen Sa from the cover body 10. Therefore, in the mounting device 1, as mentioned above, a notch 11CR is formed in the cover body 10 to expose the jig 20 from the cover body 10. In the mounting device 1 of this embodiment, the mounting part 40 is configured to be attachable to the accelerated degradation tester 100 such that the first direction X is vertical and the jig 20 is positioned on the lower side in the vertical direction. With this configuration, when the mounting device 1 is attached to the accelerated degradation tester 100, the jig 20 is positioned on the lower side in the vertical direction, so the notch 11CR is located on the lower side in the vertical direction of the cover body 10 (third surface 11C). Therefore, according to the mounting device 1, even if moisture enters the space SR inside the cover body 10, the moisture will flow downward in the vertical direction. The water is drained to the outside of the cover body 10 through the gap between the portion of the jig 20 that penetrates the notch 11CR and the inner wall of the cover body 10 that forms the notch 11CR. In this way, the mounting device 1 can prevent moisture from remaining in the space SR where various electronic components are housed.

[0065] Furthermore, in the mounting device 1, the cover body 10 includes a cover body main body 11 in which a space SR is formed on the inside, and a flange portion 12 that protrudes from the side of the cover body main body 11 opposite to the space SR side. In the direction (second direction Y) in which the flange portion 12 protrudes from the cover body main body 11, an elastic member 60 is provided on the surface 12F of the flange portion 12 opposite to the side of the cover body main body 11 (outside). With this configuration, since the elastic member 60 is provided on the outer surface 12F of the cover body 10, the adhesion of the cover body 10 to the base plate 50 is improved. Therefore, the mounting device 1 can improve the waterproof performance of the cover body 10.

[0066] Although the present invention has been described above using the above-described embodiments as examples, the mounting device 1 is not limited to these embodiments.

[0067] For example, in the above-described embodiment, an example was described in which the movement-granting mechanism 30 is housed inside the cover body 10 and the jig 20, respectively. However, for example, the entire movement-granting mechanism 30 may be housed in the space SR inside the cover body 10 by configuring the connecting portion 31 such that the tip 311T of the braking shaft 311 of the connecting portion 31 and the tips 312T, 312T of the two guide shafts 312, 312 each terminate inside the inner portion 21A of the jig 20.

[0068] Furthermore, for example, a photogenerator capable of generating electricity from artificial or natural light may be installed on the outer surface of the cover body 10 (modification 1). According to this modification 1, the movement mechanism 30 can be operated by electricity generated by the photogenerator in addition to, or instead of, the power from the battery 34, and the battery 34 can be omitted or miniaturized.

[0069] Furthermore, for example, a light sensor or a temperature sensor may be installed on the outer surface (surface) of the cover body 10 (modification 2). According to this modification 2, it is possible to impart a compressive or tensile movement to the subject Sa based on the brightness and temperature inside the test chamber 101. More specifically, for example, if it is detected that the environment inside the test chamber 101 is bright and hot, it is possible to impart a compressive movement to the subject Sa, assuming that the wall material on which the sealing material is provided is in an environment where it is expanding. Conversely, if it is detected that the environment inside the test chamber 101 is dark and cold, it is possible to impart a tensile movement to the subject Sa, assuming that the wall material is in an environment where it is contracting. Therefore, according to modification 2, it is possible to impart a movement to the subject Sa that is more in line with the natural environment.

[0070] Furthermore, those skilled in the art can modify the present invention as appropriate in accordance with conventionally known knowledge. Such modifications, insofar as they still possess the configuration of the present invention, are of course included within the scope of the present invention. [Explanation of symbols]
