Description

[Technical Field]

[0001] The present disclosure relates to an information output method, a lock, a door, an information output device, and an information output program. [Background technology]

[0002] There are universal design products available that achieve a small operating angle for interior door handles that are easy for even the elderly and children to open. Conventional technology for reducing the operating angle of door handles involves connecting an additional part to the hub part inside the locking box that retracts the latch when unlocking the door, and applying the principle of leverage to achieve a small operating angle while maintaining the amount of latch retraction.

[0003] If the operating angle of the door handle is reduced, stress will be concentrated, which may cause strain on the internal parts of the lock, leading to deformation or damage. If a part is damaged, it may become stuck inside the door, making it impossible to operate the handle, which could lead to someone being trapped inside the door.

[0004] Doors with a retractable latch function are often required to have a luxurious and stately feel. However, since sensibilities vary from person to person, it is necessary to objectively evaluate the sensible value of a door so that it can resonate with as many people as possible. Patent Document 1 discloses a method for objectively evaluating the sensible value of a sliding door or other sliding opening / closing device. [Prior art documents] [Patent documents]

[0011] Hereinafter, embodiments of the information output method, box lock, door, information output device, and information output program of the present disclosure will be described with reference to Figures 1 to 21. The following embodiment shows one aspect of the present disclosure, does not limit the disclosure, and can be modified as desired within the scope of the technical concept of the present disclosure. In addition, in the following drawings, the scale of each structure is different from the actual structure to make each configuration easier to understand.

[0012] As shown in FIG. 1, the locking device 101 includes a locking box 100 and a striker 3. The locking box 100 is detachably attached to a door 1. The door 1 is, for example, a hinged door. The door 1 is supported by a frame 5 provided in an opening 6 of a wall 4 so that the opening 6 can be opened and closed. The frame 5 has a doorstop 5A on the door-edge side that protrudes in the viewing direction. The door 1 comes into contact with the doorstop 5A when closed.

[0013] The box lock 100 is attached by being inserted into a recess provided in the side surface 1a of the door 1. The box lock 100 is replaceable with respect to the door 1. A lever handle 2 is attached to the door 1. When the lever handle 2 is operated, a latch 11 extends and retracts from the side surface 1a of the door 1. When the door 1 is closed, the latch 11 protrudes from the side surface 1a of the door 1 and is inserted into a striker 3 provided in the frame portion 5. The striker 3 incorporates a first magnet 3A. The latch 11 incorporates a second magnet 3B. When the door 1 is closed, the latch 11 protrudes from the side surface 1a of the door 1 due to the magnetic attraction between the first magnet 3A and the second magnet 3B. The latch 11 is a magnetic latch that protrudes from the side surface 1a of the door 1 due to the magnetic attraction between the first magnet 3A and the second magnet 3B. When the latch 11 is inserted into the striker 3 of the frame 5, the door 1 is kept closed.

[0014] [Box Lock 100] 2 and 3, the locking box 100 includes a case 30, a latch bolt 10, a latch hub 20, a locking portion 40, a lever portion 50, and a front plate 31. In FIG. 2, the locking portion 40 is not shown.

[0015] The case 30 accommodates the latch bolt 10, latch hub 20, locking portion 40, and lever portion 50 inside. The box lock 100 is attached to the door 1 by inserting the case 30 into a recess provided in the side surface 1a. The case 30 has a housing 30A and a lid portion 30B. The housing 30A accommodates the latch bolt 10, latch hub 20, locking portion 40, and lever portion 50 inside. The lid portion 30B is stacked on the housing 30A in the thickness direction of the case 30 to close the opening of the housing 30A.

[0016] The latch bolt 10 is provided so as to be movable back and forth in the left-right direction in FIG. 3 relative to the case 30. In the following description, the direction of movement of the latch bolt 10 is referred to as the left-right direction. The backward side of the forward movement direction is referred to as the right side, and the forward side is referred to as the left side. The up-down direction in FIGS. 2 and 3 is referred to as the up-down direction. The direction perpendicular to the left-right direction and the up-down direction in FIG. 2 is referred to as the thickness direction.

[0017] The latch bolt 10 has a shaft shape extending in the left-right direction. The latch bolt 10 has a latch 11, an engaging portion 12, an actuating portion 13, a spring 14, and a hole portion 15. The latch 11 is provided at the left end of the latch bolt 10. When the latch bolt 10 moves to the left, the latch 11 protrudes from the front plate 31 through an opening 31a in the front plate 31. The latch 11 has a second magnet 3B inside. The second magnet 3B has a cylindrical shape extending in the left-right direction. The second magnet 3B is not limited to a cylindrical shape and may have a rectangular prism shape, such as a square prism shape. The second magnet 3B is arranged to the left of the latch 11.

[0018] The locking portion 12 is disposed on the right side of the latch 11. The dimensions of the locking portion 12 are larger than the dimensions of the opening 31a in the front plate 31. When the latch bolt 10 moves to the left due to the magnetic attraction between the first magnet 3A and the second magnet 3B, the locking portion 12 locks onto the front plate 31 from the right side. By locking the locking portion 12 onto the front plate 31 from the right side, the position of the latch 11 protruding from the front plate 31 is determined.

[0019] The operating portion 13 is located at the right end of the latch bolt 10. The operating portion 13 is disposed to the right of the first arm portion 21 and the lever portion 50 of the latch hub 20 in a first position, which will be described later. The operating portion 13 can come into contact with the lever portion 50.

[0020] Hole 15 is formed in a rectangular shape extending to the right from locking portion 12. Hole 15 penetrates latch bolt 10 in the thickness direction. Wall 16, which protrudes from case 30 toward the interior of the vehicle, is inserted into hole 15. Wall 16 is positioned so that it does not come into contact with latch bolt 10 when latch bolt 10 moves between the locked position where locking portion 12 is locked to front panel 31 and the unlocked position where locking portion 12 is locked to locking wall 17.

[0021] The spring 14 is disposed in the hole 15. The left end of the spring 14 contacts the wall 16 from the right side. The right end of the spring 14 contacts the latch bolt 10 from the left side. The spring 14 is a compression spring. The spring 14 biases the wall 16 and the latch bolt 10 in the left-right direction, moving them away from each other. The spring 14 biases the latch bolt 10 to the right relative to the case 30. The spring 14 biases the latch 11 in the direction of retracting it into the case 30 via the latch bolt 10.

[0022] The biasing force of the spring 14 is smaller than the force due to the magnetic attraction between the first magnet 3A and the second magnet 3B. When the door 1 is closed, the latch 11 protrudes from the side surface 1a of the door 1 against the biasing force of the spring 14 due to the magnetic attraction between the first magnet 3A and the second magnet 3B. When the door 1 is opened, the magnetic attraction between the first magnet 3A and the second magnet 3B is released, and the latch 11 is drawn into the case 30 by the biasing force of the spring 14.

[0023] The latch hub 20 rotates around a central axis J1 extending in the thickness direction. The latch hub 20 has a first arm portion 21, a second arm portion 22, and a shaft fitting portion 23. The shaft fitting portion 23 is cylindrical and extends in the direction of the central axis J1, opening toward the interior of the vehicle. The shaft 2a of the lever handle 2 shown in FIG. 1 fits into the shaft fitting portion 23. By operating the lever handle 2 with the shaft 2a fitted in the shaft fitting portion 23, the latch hub 20 can rotate in a first circumferential direction around the central axis J1.

[0024] As shown in Fig. 4, the first arm portion 21 extends upward from the shaft fitting portion 23. The first arm portion 21 has a gap S1 at a position where it overlaps with the latch bolt 10 in the thickness direction. The latch bolt 10 is inserted into the gap S1 of the first arm portion 21. The latch bolt 10 inserted into the gap S1 of the first arm portion 21 can move in the left-right direction without interfering with the first arm portion 21.

[0025] The first arm portion 21 has a guide shaft 21A and a recess 21B at its tip end. The guide shafts 21A are provided on both sides in the thickness direction. The guide shafts 21A protrude from the first arm portion 21 along a rotation axis J2 extending in the thickness direction. The rotation axis J2 is parallel to the central axis J1. As shown in FIG. 2, the guide shafts 21A are inserted into guide grooves 30C formed in the housing 30A and the lid portion 30B, respectively, from the inside in the thickness direction, as shown in FIG. 5. The guide grooves 30C are formed in an arc shape extending in a first circumferential direction centered on the central axis J1. The guide grooves 30C have an arc length that includes the range of movement of the guide shaft 21A when the latch hub 20 rotates. The latch hub 20 rotates with the guide shaft 21A guided by the guide grooves 30C.

[0026] The recesses 21B are provided on both sides of the first arm portion 21 facing the gap S1. The recesses 21B are recessed outward in the thickness direction from the surface of the first arm portion 21 facing the gap S1. The recesses 21B have a circular cross section centered on the rotation axis J2. The recesses 21B are arranged coaxially with the guide shaft 21A. A shaft portion 51, which will be described later, is fitted into the recesses 21B so as to be rotatable about the rotation axis J2.

[0027] The second arm portion 22 extends downward from the shaft fitting portion 23. The left side of the second arm portion 22 contacts the end face of the slider 34. The slider 34 is provided within the case 30 so as to be movable left and right. The left side of the slider 34 contacts the spring 24. The spring 24 is a compressed coil spring. The right side of the spring 24 contacts the slider 34, and the left side contacts the side wall 33 of the case 30. The slider 34 is biased to the right by the biasing force of the spring 24. As the spring 24 biases the slider 34 to the right, the second arm portion 22 is movable in the counterclockwise direction. When the second arm portion 22 moves in the counterclockwise direction, the latch hub 20 rotates in the counterclockwise direction. When the latch hub 20 rotates in the counterclockwise direction, its counterclockwise rotation is restricted when it contacts the side wall 35 of the case 30. The position shown in FIG. 3 where the latch hub 20 contacts the side wall 35 and rotational movement is restricted is defined as a first position, which is the initial position where the latch 11 projects from the case 30.

[0028] The locking portion 40 is rotatable about an axis J3 parallel to the central axis J1. The locking portion 40 includes a third arm portion 41 and an axis fitting portion 43. The axis fitting portion 43 is cylindrical and extends along the axis J3 parallel to the central axis J1. The axis fitting portion 43 has a recess 43a that opens toward the interior. The position of the third arm portion 41 in the thickness direction is the same as the position of the first arm portion 21 in the thickness direction. The third arm portion 41 is movable between an unlocked position (shown in FIG. 3 ) in which it does not interfere with the first arm portion 21, which moves to the right, one side in the first circumferential direction, as the latch hub 20 rotates, and a locked position in which it is located to the right of the first arm portion 21 in the first circumferential direction and on the path of movement of the first arm portion 21. When the third arm portion 41 is in the locked position, rotation of the latch hub 20 is restricted, and the latch 11 is maintained in a state where it protrudes from the front panel 31 when the door 1 is closed. The locking portion may have a different configuration as long as the rotation of the latch hub 20 is restricted and the latch 11 is maintained in a state protruding from the front panel 31 when the door 1 is closed.

[0029] The lever portion 50 has a shaft portion 51, a first portion 52, and a second portion 53. The lever portion 50 has a gap S2 from the shaft portion 51 to the second portion 53 at a position where the lever portion 50 overlaps with the latch bolt 10 in the thickness direction.

[0030] The shaft portion 51 is provided on both sides in the thickness direction. The shaft portion 51 is hemispherical and protrudes from the lever portion 50 along the rotation axis J2. The shaft portion 51 fits into the recess 21B of the first arm portion 21 so as to be rotatable about the rotation axis J2. By fitting the shaft portion 51 into the recess 21B, the lever portion 50 is attached to the latch hub 20 so as to be movable together with the latch hub 20 in a first circumferential direction. By fitting the shaft portion 51 into the recess 21B, the lever portion 50 can rotate in a second circumferential direction around the rotation axis J2 relative to the latch hub 20.

[0031] In the lock box 100, the lever portion 50 has the shaft portion 51 and the first arm portion 21 has the recessed portion 21B, but the lever portion 50 may have the recessed portion and the first arm portion 21 may have the shaft portion.

[0032] The first portion 52 extends from the rotation axis J2 in a direction away from the central axis J1. The first portion 52 has an engagement portion 52A at its tip end. The engagement portion 52A is a cylindrical protrusion that protrudes on both sides in the thickness direction. As shown in FIG. 2, the engagement portion 52A is inserted into grooves 30D formed in the housing 30A and the lid portion 30B from the inside in the thickness direction, as shown in FIG. 5. When the latch hub 20 is in the first position, the engagement portion 52A is located above and to the left of the shaft portion 51.

[0033] The latch bolt 10 is inserted into the gap S2 of the second portion 53. The latch bolt 10 inserted into the gap S2 of the second portion 53 can move left and right without interfering with the second portion 53. The second portion 53 extends from the rotation axis J2 in a direction approaching the central axis J1. The second portion 53 has a moving portion 53A on its tip side. When the latch hub 20 is in the first position, the moving portion 53A is located below and to the right of the shaft portion 51. The maximum distance of the moving portion 53A from the rotation axis J2 is longer than the maximum distance from the rotation axis J2 to the engagement portion 52A.

[0034] Because the maximum distance from the rotation axis J2 to the moving part 53A is longer than the maximum distance from the rotation axis J2 to the engagement part 52A, when the lever part 50 rotates around the rotation axis J2 to one side in the second circumferential direction, which is the counterclockwise direction in Figures 3 and 4, the amount of displacement of the moving part 53A to the right is greater than the amount of displacement of the engagement part 52A to the left.

[0035] As shown in FIG. 6, the case 30 has a groove 30D into which the engaging portion 52A is movably fitted. The groove 30D has a first groove 30E and a second groove 30F. The first groove 30E extends in a radial direction centered on the central axis J1. The engaging portion 52A of the lever portion 50 fits into the first groove 30E when the latch hub 20 is in the first position. Of the edges of the case 30 facing the first groove 30E, the edge located on the right side in the first circumferential direction is the engaging wall 32. The engaging wall 32 can engage with the engaging portion 52A from the right side in the first circumferential direction.

[0036] The second groove portion 30F extends to the right from the end of the first groove portion 30E that is closer to the central axis J1. The distance of the second groove portion 30F from the path of movement of the rotation axis J2 accompanying rotation of the latch hub 20 gradually increases toward the right in the first circumferential direction. The distance of the second groove portion 30F from the rotation axis J2 gradually increases toward the right in the first circumferential direction.

[0037] The case 30 has an opposing wall 36 and a curved wall 37. The opposing wall 36 is an edge of the case 30 facing the second groove portion 30F, on the side farther from the central axis J1. The opposing wall 36 extends to the right from the end of the engagement wall 32 closer to the central axis J1. When the engagement portion 52A is fitted into the second groove portion 30F, the opposing wall 36 faces the engagement portion 52A on the side farther from the central axis J1. The curved wall 37 connects the engagement wall 32 and the opposing wall 36. The curved wall 37 is curved in an arc shape with a center of curvature on the side farther from the central axis J1 when viewed in a direction along the central axis J1.

[0038] In the box lock 100, when the latch hub 20 is rotated from the first position to the right in the first circumferential direction by operating the lever handle 2, the lever portion 50 moves to the right in the first circumferential direction together with the first arm portion 21. When the lever portion 50 moves to the right in the first circumferential direction, the engaging portion 52A engages with the engaging wall 32 from the left side in the first circumferential direction. When the engaging portion 52A engages with the engaging wall 32, the movement of the engaging portion 52A to the right is restricted, but the first arm portion 21 and the lever portion 50, whose shaft portion 51 fits into the first arm portion 21, continue to move to the right.

[0039] As the lever portion 50 continues to move to the right, the engagement portion 52A, which was engaged with the engagement wall 32 in the first groove portion 30E, moves to one side in the second circumferential direction around the rotation axis J2, as shown in Figure 7, and moves along the first groove portion 30E toward the side closer to the center axis J1 until it intersects with the second groove portion 30F.

[0040] The engaging portion 52A, which has moved along the first groove portion 30E toward the side closer to the central axis J1 while engaged with the engaging wall 32, sequentially engages with the engaging wall 32, the curved wall 37, and the opposing wall 36 and fits into the second groove portion 30F as the lever portion 50 continues to move to the right. The engaging portion 52A fitted into the second groove portion 30F faces the opposing wall 36.

[0041] If the curved wall 37 is not provided and the engaging wall 32 and the opposing wall 36 are connected, the movement direction of the engaging portion 52A changes suddenly from the direction toward the central axis J1 to the direction along the second groove portion 30F. This sudden change in the movement direction of the engaging portion 52A may cause an impact when the latch hub 20 is rotated from the first position to the right in the first circumferential direction by operating the lever handle 2, which may cause a sense of discomfort to the user.

[0042] When the engagement wall 32 and the opposing wall 36 are connected by the curved wall 37, the movement direction of the engagement portion 52A is the tangent direction of the curved wall 37 at the position where the engagement portion 52A contacts the engagement portion 52A. Because the tangent direction changes continuously from the position where the curved wall 37 connects with the engagement wall 32 to the position where the curved wall 37 connects with the opposing wall 36, the movement direction of the engagement portion 52A changes continuously from the direction toward the central axis J1 to the direction along the second groove portion 30F. Because the movement direction of the engagement portion 52A changes continuously, it becomes possible to smoothly rotate the latch hub 20 to the right in the first circumferential direction from the first position by operating the lever handle 2, without causing the user any discomfort.

[0043] Because the maximum distance of the moving portion 53A from the rotation axis J2 is longer than the maximum distance from the rotation axis J2 to the engaging portion 52A, when the engaging portion 52A rotates in one direction in the second circumferential direction to a position where it intersects with the second groove portion 30F, the amount of rightward displacement of the moving portion 53A relative to the rotation axis J2 is greater than the amount of leftward displacement of the engaging portion 52A relative to the rotation axis J2, as shown in FIG. 8 . The moving portion 53A protrudes rightward beyond the first arm portion 21 and abuts against the operating portion 13 of the latch bolt 10, pressing it rightward. As the operating portion 13 is pressed rightward by the moving portion 53A, the latch 11 of the latch bolt 10, biased by the biasing force of the spring 14, moves rightward against the magnetic attraction between the first magnet 3A and the second magnet 3B and is drawn into the case 30. When the latch 11 moves rightward against the magnetic attraction between the first magnet 3A and the second magnet 3B, the door 1 is unlocked and can be opened.

[0044] The latch 11 is unlocked within a range from when the latch hub 20 begins to rotate to the right in the first circumferential direction by operating the lever handle 2, until the engaging portion 52A moves to the right in the first circumferential direction and engages with the engaging wall 32, and then rotates to one side in the second circumferential direction and moves to a position where it intersects with the second groove portion 30F. The latch 11 is unlocked when the latch hub 20 is rotated by an operating angle of, for example, about 5° by operating the lever handle 2.

[0045] After the latch 11 is unlocked, the rotation of the latch hub 20 by operating the lever handle 2 continues until the guide shaft 21A rotates at an operating angle of approximately 10°, with the moving portion 53A remaining in contact with the operating portion 13, and reaches the right end of the guide groove 30C, as shown in Figures 9 and 10. After the latch 11 is unlocked when rotated at an operating angle of approximately 10°, the operation of the lever handle 2 continues until the moving portion 53A rotates at an operating angle of approximately 10°, with the moving portion 53A remaining in contact with the operating portion 13, making it easy to see that the latch has been unlocked.

[0046] Because the distance of the second groove portion 30F from the rotation axis J2 gradually increases toward the right in the first circumferential direction, when the latch hub 20 continues to rotate due to operation of the lever handle 2 after the latch 11 is unlocked, the engagement portion 52A rotates toward the other side in the second circumferential direction relative to the rotation axis J2. As the engagement portion 52A rotates toward the other side in the second circumferential direction relative to the rotation axis J2 after the latch 11 is unlocked, the amount of rightward displacement of the moving portion 53A relative to the rotation axis J2 gradually decreases. As the amount of rightward displacement of the moving portion 53A gradually decreases, the load associated with the moving portion 53A contacting and pressing the operating portion 13 to the right decreases. As the load when the moving portion 53A presses the operating portion 13 decreases, damage to the lever portion 50 is suppressed even when the operation angle required for unlocking is reduced.

[0047] According to the box lock 100 and lock device 101, the maximum distance from the rotation axis J2 to the moving part 53A is longer than the maximum distance from the rotation axis J2 to the engaging part 52A, and when the engaging part 52A of the lever part 50, which is movable in the first circumferential direction together with the latch hub 20, engages with the engaging wall 32 of the case 30, it rotates to one side in the second circumferential direction, and the moving part 53A abuts against the operating part 13 and presses it to the right, thereby reducing the operating angle until unlocking. According to the box lock 100 and lock device 101, after the latch 11 is unlocked, the lever part 50 rotates to one side in the first circumferential direction together with the latch hub 20 with the moving part 53A abutting against the operating part 13, making it easy to tell that the latch has been unlocked.

[0048] According to the box lock 100 and the locking device 101, the distance of the second groove portion 30F from the rotation axis J2 gradually increases toward the right in the first circumferential direction, so that the amount of displacement of the moving portion 53A toward the right gradually decreases after the latch 11 is unlocked, thereby preventing the load applied to the lever portion 50 from increasing and causing damage to the lever portion 50.

[0049] According to the box lock 100 and the locking device 101, a curved wall 37 is provided which is curved in an arc shape with a center of curvature on the side farther from the central axis J1 when viewed in the direction along the central axis J1 and connects the engagement wall 32 and the opposing wall 36. Therefore, the direction of movement of the engagement portion 52A changes continuously, and the latch hub 20 can be smoothly rotated from the first position to the right in the first circumferential direction by operating the lever handle 2 without causing the user any discomfort.

[0050] [Information output device] As shown in Fig. 11, the information output device 110 includes a processing unit 120. The processing unit 120 includes an acquisition unit 122 and an output unit 124. The acquisition unit 122 and the output unit 124 of the processing unit 120 are realized by a combination of hardware elements and software elements, or by hardware elements only. The hardware elements include a processor and memories such as a ROM (Read Only Memory) and a RAM (Random Access Memory). The software elements include programs such as an operating system and applications.

[0051] As will be described later, the program is an information output program that causes a computer to perform the following operations: rotate the latch hub 20 and acquire physical property information indicating the physical properties of the locking box 100 when the latch bolt 10 moves via the lever portion 50; and output perceptual value information indicating the perceptual value based on the acquired physical property information using an output model that is created based on the evaluation results of multiple people on the perceptual value of the locking box relative to its physical properties, and that outputs perceptual value from the physical property information.

[0052] The acquisition unit 122 acquires physical property information and emotional value information, which will be described later. The output unit 124 outputs the physical property information and emotional value information via a display, a printer, or the like.

[0053] In order to create a beautiful background for the interior space, the locking box 100 and the door 1 pursue "elaboration," also known as "good construction." Values ​​related to human sensibilities, such as "elaboration," have been subjectively evaluated by product developers and others. This sensible value manifests itself by appealing to people's sensibilities and gaining their sympathy, and therefore varies greatly depending on the user's sensibility. Even if one user perceives the locking box 100 and the door 1 as "elaborate," this does not necessarily mean that it will be accepted by other users. A method for objectively evaluating the sensible value of the locking box 100 and the door 1 is needed so that it can be sympathized with by more users.

[0054] The inventors conducted extensive research to address this issue. As a result, they found that, in the opening operation of the latch 11, specific physical characteristics of the box lock 100 when the latch hub 20 is rotated and the latch bolt 10 moves via the lever portion 50, and specific physical characteristics when the door 1 is closed, are strongly correlated with specific user sensibilities. Regarding the opening operation of the latch 11, they found that ease of opening and smooth movement are strongly correlated with human sensibilities. When the door 1 is closed, they found that the pleasant closing sound of the door 1 and the pleasant latch sound are strongly correlated with human sensibilities. By utilizing this knowledge, the sensibilities of the box lock 100 and the door 1 can be objectively evaluated from objective information, namely the physical characteristics of the box lock 100 and the door 1, enabling product development where sensibilities are supported by data.

[0055] The information output process by the information output device 110 will be described with reference to the flowchart in Fig. 12. The information output device 110 outputs information about the opening and closing operation of the latch 11 in the locking box 100. The information output device 110 has a processing unit 120. The processing unit 120 has an acquisition unit 122 and an output unit 124.

[0056] In step S10, the acquisition unit 122 acquires physical property information indicating the physical properties of the locking box 100 and the door 1 via measuring devices such as a load cell, a gyro sensor, a microphone, etc. The locking box 100 and the door 1 are parts of building fixtures. The physical property information in this embodiment includes operation angle data indicating the rotation angle when the latch hub 20 is rotated in the opening direction of the latch 11 via the lever handle 2, load data indicating the transition of the load during the rotation operation, and also includes acoustic data when the door 1 is closed.

[0057] The output unit 124 outputs the obtained physical property information in step S12. The output unit 124 outputs the operation angle data, the load data, and the sound data via a display or the like.

[0058] In step S14, the acquisition unit 122 acquires perceptual value information indicating the perceptual value related to the lock box 100 and the door 1 based on the acquired physical property information using an output model that outputs the perceptual value related to the lock box 100 and the door 1 from the physical property information. The output model is an output model created according to the evaluation results by multiple people of the perceptual value related to the lock box 100 and the door 1 for the physical properties, and is stored in advance in the memory of the processing unit 120. The output model includes regression equations of equations (1) and (2) described below.

[0059] In step S16, the output unit 124 outputs the acquired affective value information. The output unit 124 outputs the operation precision and the sound precision. By the output unit 124 outputting the operation precision and the sound precision, it becomes possible to provide objective indicators of the degree of precision regarding the opening operation of the latch 11 and the degree of precision regarding the sound generated when the door 1 is closed.

[0060] In step S16, the output unit 124 outputs an evaluation result as to whether or not the perceptual values ​​related to the lock box 100 and the door 1 satisfy a predetermined standard based on the output perceptual value information. In step S18, the output unit 124 outputs an evaluation result as to whether or not the perceptual values ​​related to the lock box 100 and the door 1 satisfy a predetermined standard based on the output perceptual value information. Below, the opening operation of the latch 11 and each step when the door 1 is closed will be described in detail.

[0061] [Opening latch 11] In step S10, the lever handle 2 was attached to the latch hub 20 of the box lock 100 attached to the door 1, and the operation angle and load data were measured as physical property information using a load cell and gyro sensor attached to the lever handle 2. The distance from the center of rotation of the lever handle 2 to the load cell, which is the point of force, was set to 75 mm. The load data, which is the operation force, was measured individually for all subjects who participated in the sensory evaluation. The operation angle is calculated as the operation angle of the lever handle 2 by integrating the angular velocity data obtained by the gyro sensor over time.

[0062] The operation angle and load data were measured using prototypes A and B of the box lock 100 and specimen CE. Prototype A is the box lock shown in Figure 1-10. Prototype B is a box lock in which, unlike the box lock of prototype A, the curved wall 37 is not provided on the case 30 facing the groove portion 30D, and the engaging wall 32 and the opposing wall 36 are directly connected, with the intersection of the engaging wall 32 and the opposing wall 36 forming an edge. Specimen CE is a commercially available box lock that does not have a lever portion 50, unlike the box lock shown in Figure 1-10. Figure 13 shows the results of measuring the operation angle and load data using prototypes A and B and specimen CE.

[0063] As shown in Figure 13, prototypes A and B and specimen D had small operating angles, resulting in short operating times. Specimens C and E had large operating angles, resulting in long operating times. Prototypes A and C had small maximum loads, while prototypes B and DE had large maximum loads. Prototype B had a small operating angle and short operating times, but the load reached a large maximum value during the initial operation, then decreased to a small minimum value, resulting in a large drop.

[0064] In prototype B, the engaging wall 32 and the opposing wall 36 are connected without the curved wall 37 in the case 30, and it is assumed that the load difference is large because the movement direction of the engaging portion 52A changes suddenly from the direction toward the central axis J1 to the direction along the second groove portion 30F. In prototype A, the engaging wall 32 and the opposing wall 36 are connected by the curved wall 37, and it is assumed that the movement direction of the engaging portion 52A changes continuously, which prevents the load from increasing suddenly during initial operation and causes the load to increase gradually.

[0065] Based on the results of interviews conducted in advance using the evaluation grid method, repeated interviews and sensory evaluations, including preliminary experiments, were conducted. Further examination was carried out using the paired comparison method, and finally a sensory evaluation was carried out using the semantic differential (SD) method using the following 11 adjective pairs. For the sensory evaluation, subjects were selected from the product purchasing demographic, and a total of 22 subjects operated the lever handle to open the latch of box lock prototypes A and B and test piece CE.

[0066] 1. Not easy to operate - It is easy to operate. 2. Wobble - Don't wobble. 3. Doesn't move smoothly - moves smoothly. 4. Not a small angle - the angle is small. 5. The latch does not unlock quickly - The latch unlocks quickly. 6 Not easy to open - Easy to open. 7. Not fitting the concept - Fits the concept. 8. Not well made - Well made. 9. Don't feel stylish - feel stylish. 10. It doesn't feel advanced - It feels advanced. 11. I don't feel any attachment - I feel some attachment.

[0067] As shown in Figure 14, test piece C received many negative evaluations overall. For "precision," prototype A, test pieces D, and E received roughly the same scores. For prototype B, there were many negative evaluations for smooth movement and ease of opening, but many positive evaluations for the small operating angle. For prototype A, there were many positive evaluations overall, including for smooth movement, ease of opening, and small operating angle.

[0068] Multivariate analysis was used to confirm the correlation between the above-mentioned adjectives, and it was found that "precision" was highly correlated with "easy to open" and "smooth operation." Four characteristics associated with these two adjectives were extracted as characteristic values: "maximum operating force," "operating force drop," "maximum lever handle operating angle," and "lever handle operating time." "Operating force drop" is the difference between the minimum value after the operating force reaches its maximum value. "Lever handle operating time" uses data before integrating "lever handle operating angle."

[0069] Of the 11 adjective pairs, functional items No. 1-5 were analyzed using a factor analysis with Promax rotation. The results of the factor analysis showed that the first factor was related to the "operation angle" and the second factor was related to the load caused by the "smoothness of rotation."

[0070] In step S14, the degree of operation precision, which indicates the degree of precision regarding the latch opening operation, is obtained as perceptual value information based on the measured physical property information. The perceptual value information was subjected to multiple regression analysis using the degree of operation precision as the objective variable and the first and second factors as explanatory variables, and in step S16, regression equation (1) with a coefficient of determination R2 of 0.42 was obtained as the output result, as shown in Figure 15.

[0071] [Operation precision]=0.29×1st factor+0.97×2nd factor+0.07…(1).

[0072] A multiple regression analysis was performed using the first factor as the dependent variable and "maximum lever handle operating angle" and "lever handle operating time" from among the characteristic values ​​associated with the two adjectives mentioned above as explanatory variables, and the following regression equation, which has a good fit with a coefficient of determination R2 of 0.81, was obtained as the output result, as shown in Figure 16. "Lever handle operating time" was set to 0.16-0.89 seconds.

[0073] [Factor 1] = -0.08 × [Maximum lever handle angle] - 0.36 × [Lever handle operation time] + 1.58

[0074] A multiple regression analysis was performed using the second factor as the dependent variable and "maximum operating force," "operating force difference," and "lever handle operating time" from among the characteristic values ​​associated with the two adjectives mentioned above as explanatory variables. As a result, the following regression equation, which has a good fit with a coefficient of determination R2 of 0.42, was obtained as the output, as shown in Figure 17. "Maximum operating force" was set to 7.8-46.7 N. "Operating force difference" was set to 0-10.3 N. "Lever handle operating time" was set to 0.16-0.89 sec.

[0075] [Second factor] = -0.04 x [Maximum operating force] -0.75 x [Maximum operating angle of lever handle] -0.12 x [Operating force drop] + 1.43

[0076] In step S18, the output unit 124 outputs an evaluation result indicating whether the perceptual value of the lockbox 100 satisfies a predetermined standard based on the output perceptual value information. For example, if the operation precision is greater than a predetermined standard value, the output unit 124 outputs an evaluation result indicating that the operability of the lockbox 100 satisfies the standard, and if the operation precision is equal to or less than the predetermined standard value, the output unit 124 outputs an evaluation result indicating that the operability of the lockbox 100 does not satisfy the standard. By outputting an evaluation result indicating whether the perceptual value of the lockbox 100 satisfies the predetermined standard, the output unit 124 enables product development that corresponds to the perceptual value desired for the product regarding the operability of the lockbox 100.

[0077] [When door 1 is closed] In order to quantify how the subject perceived the closing sound when the door 1 was closed and contacted with the doorstop 5A, in step S10, an acoustic measurement system (DS-5000 manufactured by Ono Sokki) was used to measure acoustic data such as the closing sound as physical property information. A microphone was placed 150 mm away from the front of the latch 11 to measure the sound. As with the operating force, it would be preferable to collect data for each subject, but this is difficult due to the characteristics of the parameter, so representative data was used.

[0078] Acoustic data was measured when the door 1 equipped with prototypes A, B, and specimen FH of the lock box 100 was closed. Figure 18 shows the loudness measured using prototypes A, B, and specimen FH. For each loudness, the horizontal axis represents time and the vertical axis represents frequency.

[0079] As with the "opening operation of latch 11," we conducted repeated interviews and sensory evaluations, including preliminary experiments, based on the results of interviews conducted in advance using the evaluation grid method.Furthermore, we conducted a paired comparison method and finally conducted a sensory evaluation using the semantic differential (SD) method using the following 13 adjective pairs.

[0080] 1. The latch sound is not quiet - The latch sound is quiet. 2. The latch sound is not low - the latch sound is low. 3. The latching sound is unpleasant - The latching sound is not unpleasant. 4. It's hard to tell when it's closed - It's easy to tell when it's closed. 5. The door is not quiet - The door is not quiet. 6. The door hitting sound is not low - The door hitting sound is low. 7. The sound of the door hitting the door echoes - The sound of the door hitting the door does not echo. 8. The door hitting sound is unpleasant - The door hitting sound is not unpleasant. 9. Not fitting the concept - Fits the concept. 10. Not well made - Well made. 11. Don't feel stylish - feel stylish. 12. Not feeling advanced - feeling advanced. 13. I don't feel any attachment - I feel attachment.

[0081] As shown in Figure 19, when closing Door 1, test pieces F and G generally received negative evaluations. Test piece G and prototype B were highly rated overall, and prototype A also received high evaluations for "precision."

[0082] Multivariate analysis was used to confirm the correlation between the above-mentioned adjectives, and it was found that "precision" was highly correlated with "closing sound is not unpleasant" and "latching sound is not unpleasant." Since people generally perceive loud or high-pitched sounds as unpleasant, four characteristic values ​​were extracted: "maximum loudness of latching sound," "frequency of maximum loudness of latching sound," "maximum loudness of door-hitting sound," and "reverberation time of door-hitting sound."

[0083] As with "opening operation of latch 11," factor analysis was performed to confirm the fit of each factor with the characteristic value, but the characteristic values ​​selected were the same for all factors.In order to simplify the regression equation, a regression equation between "elaboration" and the characteristic value was calculated without factor analysis.

[0084] In step S14, based on the measured physical property information, sound sophistication, which indicates the degree of sophistication of the sound generated when closing the door 1, is obtained as perceptual value information. For the perceptual value information, multiple regression analysis was performed using sound sophistication as the objective variable and "frequency of maximum loudness of latch sound" as the third factor and "maximum loudness of door hitting sound" as the fourth factor as explanatory variables among the characteristic values. As a result, in step S16, regression equation (2) with a coefficient of determination R2 of 0.44 was obtained as the output result, as shown in Fig. 20.

[0085] [Sound precision] = -0.0003 x 3rd factor - 0.44 x 4th factor + 2.53...(2).

[0086] It is generally known that sounds that are too loud are unpleasant from the perspective of noise. For example, sounds in the 3000-6000 Hz range, such as the sound of scratching a blackboard, are known to be unpleasant to all human beings, regardless of race or culture. Many research studies have also been published showing that sounds in the 2000-9000 Hz range are unpleasant.

[0087] Using the data from this sensory evaluation, we confirmed the relationship between the adjective pair "The latch sound is unpleasant - The latch sound is not unpleasant" and the "maximum loudness frequency of the latch sound." As shown in Figure 21, we confirmed that there is a strong correlation between the unpleasantness of the latch sound and its frequency.

[0088] In step S18, the output unit 124 outputs an evaluation result indicating whether the perceptual value related to the door 1 satisfies a predetermined standard based on the output perceptual value information. For example, if the sound sophistication is greater than a predetermined standard value, the output unit 124 outputs an evaluation result indicating that the sound when the door 1 is closed satisfies the standard, and if the sound sophistication is equal to or less than the predetermined standard value, the output unit 124 outputs an evaluation result indicating that the sound when the door 1 is closed does not satisfy the standard. By outputting an evaluation result indicating whether the perceptual value related to the sound when the door 1 is closed satisfies the predetermined standard, the output unit 124 enables product development that corresponds to the perceptual value desired for the product regarding the sound when the door 1 is closed.

[0089] In the information output method, the box lock, the door, the information output device, and the information output program of the embodiments, information for objectively evaluating the emotional value of the box lock 100 and the door 1 can be obtained.

[0090] In the lock box 100 of the embodiment, good emotional value can be obtained by providing information for objective evaluation.

[0091] While preferred embodiments of the present disclosure have been described above with reference to the accompanying drawings, it goes without saying that the present disclosure is not limited to these examples. The shapes and combinations of the components shown in the above examples are merely examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of the present disclosure.

[0092] For example, the box lock 100 and door 1 in the embodiment are configured such that the striker 3 incorporates a first magnet 3A, the latch 11 incorporates a second magnet 3B, and the door 1 is locked when the latch 11 protrudes from the side surface 1a of the door 1 due to the magnetic attraction between the first magnet 3A and the second magnet 3B, but are not limited to this configuration. The locking device 101 may also be configured such that the latch 11 is inserted into the striker 3 and locked when the latch bolt 10 is biased by a biasing member such as a spring.

[0093] For example, the box lock 100 and door 1 in the embodiment have been illustrated as having a configuration in which the lever portion 50 abuts against the operating portion 13 to move the latch bolt 10, but are not limited to this configuration. The box lock 100 may also have a configuration in which the lever portion 50 engages with the operating portion 13 to move the latch bolt 10.

[0094] In the embodiment, the output model of the box lock 100 and door 1 is a regression equation based on regression analysis shown in equations (1) and (2), but it may also be a learning model using a neural network created by learning the evaluation results of the perceptual value of the box lock 100 and door 1 relative to the physical properties of the box lock 100 and door 1.
