Description

  The present invention relates to a flooring test method and a testing machine for evaluating a flooring manufactured by a synthetic resin or the like covering a corridor, a balcony, a staircase or the like of an apartment house, a store, or a building.

  As a testing machine for examining the contamination, deterioration, and durability of various materials exposed to the outdoors such as exterior wall finishing materials and roofing board materials, it is installed on the sample holder on the rotating shaft that is horizontally installed in the test chamber and rotates intermittently. Mount the sample in a detachable manner, and collect the suspension from the suspension tank at the bottom of the test chamber using the collector at the tip of the sample holder. Repeated hot air spraying on the adhered sample to contaminate the sample. When hot air is sprayed, the lower part on the suspension tank side is projected by a partition plate that protrudes from the rotating shaft and rotates integrally with the rotating shaft. There is known a pollution promotion tester that temporarily partitions a space from an upper space on the hot air blowing side (Patent Document 1).

  The contamination promotion tester collects the suspension from the suspension tank at the lower part of the test chamber, and causes the collected suspension to flow down from the outer wall finishing material of the building, the roof plate material, etc. By repeatedly spraying hot air on the outer wall finishing material or the like to which the turbid liquid is adhered, contamination of the outer wall finishing material or the like is promoted, and the contamination, deterioration, and durability of these various materials are tested.

Registered Utility Model No. 3004344

  By the way, floor materials that cover floor surfaces of apartment houses, etc., when a person walks on the surface, dirt substances and solids attached to the soles (shoe soles) adhere, and wear and scratches, Alternatively, settling or the like occurs. In particular, solids attached to the soles often contain substances that wear or damage the surface of the flooring, and if dirt is attached when the flooring is worn or damaged, Dirt on the flooring will proceed at an accelerated rate. In this way, the adhesion of dirt substances and the wear and scratches on the flooring material overlap, so that the appearance of the flooring material is impaired, and functions that are inherently imparted to the flooring material, such as slip resistance and drainage. Therefore, it is required to make a situation close to the actual usage mode and evaluate it in a composite manner.

  As described above, in the flooring test for which multiple evaluations are required, in the pollution promotion tester of Patent Document 1, it is possible to attach a dirt substance to the surface of the flooring, but wear and scratches can be caused. Since it is not possible to reproduce up to and including, etc., in an actual flooring test, durability and other evaluations have been made by humans walking repeatedly on the surface of the flooring.

  However, since an enormous amount of walking data is required to perform the flooring evaluation test, there is a problem that a considerable number of experimenters are required for the test and time is required. In addition, it is difficult to accurately measure the number of times of walking, and it is difficult for a plurality of experimenters to perform a unified evaluation test under the same situation every time because the weight of each experimenter is different.

  The present invention has been made in view of the above-mentioned problems, and the problem to be solved is the same for each time the composite evaluation of the flooring such as stain resistance, abrasion resistance, scratch resistance, or sag. An object of the present invention is to provide a floor material testing method and a testing machine that can be performed accurately and quickly under the circumstances described above.

  In order to achieve the above object, a flooring test method according to the present invention is a method of testing a flooring, wherein a flooring specimen is placed on a support base, and a contact member is rotated by a drive shaft. The change of the test specimen is evaluated after being brought into contact with the surface of the test specimen several times in conjunction with the above.

In addition, the testing machine of the present invention used for the flooring test method,
A drive shaft that is rotated by a drive source;
A rod that moves substantially vertically in conjunction with the rotation of the drive shaft;
A contact member attached to the lower end of the rod;
A support base on which the floor specimen is placed;
The contact member is brought into contact with the surface of the floor specimen placed on the support base a plurality of times in conjunction with the rotation of the drive shaft.

  In the testing machine of the present invention, it is preferable that a guide portion for guiding the movement of the rod is provided below the drive shaft so as to be swingable in the front-rear direction around the pivot shaft. More preferably, the pivot shaft is located in front of the drive shaft. Further, a locking portion that is provided at a certain distance in the orthogonal direction from the drive shaft and turns with the rotation of the drive shaft is engaged with a long hole provided in the upper end portion of the rod. Preferably, the support base is provided so as to be slidable in the front-rear direction, and a stopper is provided to stop the backward sliding of the support base when the support base slides to the rear end of the slide range. preferable. Furthermore, it is preferable that load adding means for applying a load to the lower end side along the length direction of the rod is provided, and the contact member is formed from a plurality of portions connected so that the connection angle is variable. More preferably, it is configured.

  The flooring test method of the present invention evaluates changes in the flooring (stains, wear, scratches, sag, etc.) after the contact member is brought into contact with the surface of the flooring material, which is a test body, a plurality of times. It is. Since this abutment member is linked to the rotation of the drive shaft, when the drive shaft is rotated, the abutment member is linked to the surface of the flooring while performing a motion similar to the behavior of the foot during walking. Abut. Since the drive shaft rotates regularly, the contact member also regularly contacts the floor surface in the same manner each time. As described above, the present invention can be experimented under a situation similar to the actual use of the flooring material by simulating human walking, so that the stain resistance, abrasion resistance, Multiple evaluations such as scratch resistance and sag can be performed accurately and under the same conditions.

  Next, the testing machine of the present invention used in the flooring test method is attached to a drive shaft that is rotated by a drive source, a rod that moves substantially vertically in conjunction with the rotation of the drive shaft, and a lower end of the rod. In such a testing machine, when the drive shaft rotates, the associated rod moves in a substantially vertical direction. To do. And if a rod moves to a substantially up-down direction, the contact member attached to the lower end will contact | abut repeatedly on the flooring mounted on the support stand. As described above, the testing machine of the present invention can reproduce a stepping motion that is close to a human's actual walking, and when the flooring test is performed using this, the flooring material is resistant to soiling and dirt. Complex evaluations such as wear, scratch resistance, and settling can be performed accurately and quickly.

  Further, in the test machine in which a guide portion for guiding the movement of the rod is provided below the drive shaft so as to be swingable in the front-rear direction around the pivot shaft, the rod is moved back and forth along the guide portion. Since it moves substantially up and down while swinging, the contact member attached to the lower end of the rod becomes a movement similar to the movement of the foot during walking.

Here, in human walking, the angle when the leg is stepped forward (the angle of the leg with respect to the ground) is larger than the angle when the leg is kicked backward. In view of this, by making the test machine have a configuration in which the pivot shaft of the guide portion is located on the front side of the drive shaft, it is possible to reproduce a movement closer to actual walking.
Here, the “leg” refers to a portion below the thigh or knee (hereinafter the same).

  Further, a test in which a locking portion provided at a certain distance in the orthogonal direction from the drive shaft and turning with the rotation of the drive shaft is engaged with a long hole provided in the upper end portion of the rod. The machine can reproduce the situation closer to the actual walking because the weight of the rod and the contact member is added to the specimen.

  Furthermore, the tester is provided with a stopper that is slidable in the front-rear direction, and is provided with a stopper that stops the backward sliding of the support table when the support table slides to the rear end of the slide range. When the support base slides to the rear end and stops, the movement of the contact member rubbing the surface of the flooring is reproduced, so that it is possible to create a situation that is closer to a human walking on the flooring. .

  In addition, a testing machine provided with a load applying means for applying a load to the lower end side along the length direction of the rod can apply a load heavier than its own weight to the test body by the load adding means. It is possible to reproduce the same situation as a human walking. Of course, by adding a load that is greater than the human body weight, it is possible to promote the experiment by promoting the contamination, wear, scratching, and settling of the specimen.

In the testing machine in which the contact member is composed of a plurality of portions connected so that the connection angle is variable, the contact member moves in the same manner as an actual human foot. That is, in actual walking, first, the heel portion of the foot comes into contact with the floor material, then the entire sole touches the floor material, and finally the toe portion of the foot comes into contact with the foot material. Leave. By configuring this movement from a plurality of parts connected so that the connection angle is variable, the movement can be faithfully reproduced, and an experiment can be performed under a situation very close to actual walking.
Here, the “foot” refers to a portion located below the human ankle, and this “foot” refers to a part of the “leg” (hereinafter the same).

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

  The floor material test method of the present invention shown in FIGS. 1 to 4 uses the testing machine described below to reproduce the same situation as when a human is actually walking on the floor material 2. In addition, the soil resistance, wear resistance, scratch resistance, or sag of the flooring 2 is evaluated in combination.

  As shown in FIG. 1 and the like, the testing machine used for the test method of the flooring 2 includes a drive shaft 4 that is rotated by a drive source, a rod 5 that moves in a substantially vertical direction in conjunction with the rotation of the drive shaft 4, An abutting member 3 attached to the lower end of the rod 5 and a support base 1 on which a floor material 2 as a test body is placed, and abuts on the surface of the floor material 2 placed on the support base 1 The member 3 is brought into contact with the surface of the flooring 2 a plurality of times in conjunction with the rotation of the drive shaft 4.

  The drive shaft 4 is a shaft body that is rotated (clockwise in this embodiment) by a drive source such as a motor, and a disk 12 is attached to the tip of the shaft body. The disk 12 is also rotated in the same manner.

  In the vicinity of the outer peripheral edge of the surface of the disk 12, a locking portion 8 that engages with a long hole 9 to be described later is provided. The locking portion 8 is provided on the surface of the disk 12 attached to the tip of the drive shaft 4 so that a constant distance is maintained in the orthogonal direction from the drive shaft 4. In such a configuration, when the disk 12 rotates together with the rotation of the drive shaft 4, the locking portion 8 provided on the disk 12 turns clockwise about the drive shaft 4. Since the locking portion 8 is engaged with a long hole 9 provided in the upper end portion of the rod 5, the driving force of the drive shaft 4 is transmitted from the disc 12 to the rod 5 via the locking portion 8. It has become so.

  The rod 5 to which the driving force of the driving shaft 4 is transmitted is a metal round bar or pipe, and when the driving shaft 4 rotates, it moves in the vertical direction in conjunction with it. A guide portion 6 that guides the movement of the rod 5 is provided below the drive shaft 4 so as to be swingable in the front-rear direction about the pivot shaft 7, so that the rod 5 swings in the front-rear direction. Since it moves in the vertical direction while moving, it moves in the same way as the movement of the legs during actual walking.

  The pivot shaft 7 is located on the front side of the drive shaft 4, thereby reproducing a movement closer to an actual human walk. That is, in human walking, the angle when the leg is stepped forward (the angle of the leg with respect to the ground) is larger than the angle when the leg is kicked backward. In view of this, by positioning the pivot shaft 7 of the guide portion 6 in front of the drive shaft 4, as shown in FIGS. 1 and 3, an angle (vertical direction) when the lower end of the rod 5 moves forward. The angle of the rod 5 with respect to is set between 15 ° and 35 °) is larger than the angle when the lower end of the rod 5 moves backward (set between 5 ° and less than 15 °).

  When the pivot shaft 7 is positioned directly below the drive shaft 4, the angle when the lower end of the rod 5 moves forward is equal to the angle when the lower end of the rod 5 moves rearward. When the shaft 7 is positioned on the rear side of the drive shaft 4, the angle when the lower end of the rod 5 moves forward becomes smaller than the angle when the lower end of the rod 5 moves rearward. This is not preferable because the movement is not very similar to the movement of the legs during actual walking.

  In addition, a long hole 9 that engages with the locking portion 8 described above is provided in the upper end portion of the rod 5. The long hole 9 has substantially the same width dimension as the diameter of the locking portion 8, and the length dimension is determined to be slightly longer than the vertical movement dimension of the rod 5. By engaging the long hole 9 and the locking portion 8, the driving force of the drive shaft 4 is transmitted to the rod 5, and the rod 5 moves substantially vertically while swinging back and forth. ing.

  Further, a contact member 3 that contacts the surface of the flooring 2 is attached to the lower end of the rod 5. The abutting member 3 simulates the shape of a human foot (a part below the ankle), and has a plurality of parts (the first part 3a and the second part) connected so that the connection angle is variable. Part 3b). The first part 3a is formed to correspond to the heel and ankle from the arch referred to as a human foot, and the second part 3b is formed to correspond to the toe part referred to in the human foot.

The first part 3a and the second part 3b are connected by a first variable part 3c, and when a load is applied, the second part 3b rotates around the first variable part 3c. It comes to move. Further, the lower end of the rod 5 and the first part 3a are connected by a second variable part 3d, and the first part 3a rotates around the second variable part 3d. ing. In this way, the contact member 3 is composed of the first part 3a and the second part 3b, and each is connected by the variable part (the first variable part 3c and the second variable part 3d). The movement of the human foot can be faithfully reproduced.
The first variable portion 3c and the second variable portion 3d are provided with appropriate return characteristics so as to return to the original foot shape when the load on the contact member 3 is released (spring or the like). Is preferably provided).

The contact member 3 is preferably provided with a material corresponding to a shoe sole, such as rubber, resin, or leather, on the contact surface with the flooring 2. By providing rubber or the like assuming the sole of the shoe, it is possible to evaluate the flooring 2 in the same situation as a person walking, and to compare the evaluation result of the flooring 2 for each shoe sole. It becomes like this. Of course, the floor member 2 may be tested by putting actual shoes on the contact member 3.

  As described above, the contact member 3 is preferably close to the shape, hardness, and repulsive force of an actual human foot, and may be formed by coating the surface of a hard skeleton with a soft synthetic resin or rubber. For example, a simple metal flat plate may be used as the contact member 3, and the material is not limited.

  Further, load applying means 11 for applying a load from substantially the upper side to the lower end side along the length direction of the rod 5 is provided. As described above, since the long hole 9 is provided in the upper end portion of the rod 5, the weight of the rod 5 and the contact member 3 is added to the flooring 2. In addition to this, by providing the load adding means 11, it becomes possible to add a load other than its own weight to the flooring 2, and the flooring 2 under a situation very close to that a person is actually walking. An evaluation test can be performed.

The load applying means 11 is a so-called compression spring, and its spring rate is set to be equal to a load applied when a person of average weight walks. It is possible to make the spring rate of the load applying means 11 higher than the actual human body weight, and in that case, the evaluation test of the flooring 2 such as dirt, wear, scratches, and settling can be promoted. You will also be able to.
The load adding means 11 is not limited to the compression spring as in the present embodiment as long as it can apply a load from substantially above to the lower end side. For example, a weight is provided near the testing machine. By connecting the weight to the rod 5 with a belt, a load can be applied to the lower end side.

  Next, the floor material 2 to be subjected to the evaluation test is preferably a general floor material formed mainly of a thermoplastic synthetic resin such as a vinyl chloride resin, a polyolefin resin, or a polyurethane resin. Although used, rubber, wood, stone, metal, carpet vegetated with piles, or the like can be used as the test body 2. The flooring 2 is made of an anti-slip material by adding various additives such as a plasticizer, forming irregularities on the surface, or performing a surface treatment to form a coating film in order to approximate the actual usage. It is preferable to perform the test after imparting other functions such as property, drainage and antifouling properties.

  The floor material 2 is placed on the support base 1. The support base 1 on which the flooring 2 is placed is a square base, and a slide portion 1b is provided on the lower surface thereof. Then, as the slide portion 1b is slidably engaged with the rail 10a, the support base 1 slides in the front-rear direction on the rail 10a as shown in FIGS. Further, a stopper 10 (a stopper having an impact absorbing function) is provided in the vicinity of the rail 10a to stop the backward sliding of the support base 1 when the support base 1 slides to the rear end of the slide range. The projecting portion 1a projecting downward from the lower surface of the support base 1 abuts against the stopper 10 so that the support base 1 does not slide further back.

  Further, a tension spring 1c is provided on the lower surface of the support base 1, and the support base 1 slides backward as the contact member 3 moves rearward and is stopped by the stopper 10, and the contact member When 3 rises, it is pulled back forward by the tension spring 1c. Thus, even if the support base 1 slides backward and stops, when the load from above is lost (the contact member 3 is separated from the flooring 2), the support base 1 is returned to its original position (FIG. 1, The position returns to the position shown in FIG. As described above, when the support base 1 is slidable in the front-rear direction and the rearward sliding is stopped by the stopper 10, the contact member 3 rubs against the surface of the flooring 2 after the rearward sliding is stopped. The movement is reproduced, and it is possible to create a situation very close to actually walking on the flooring 2. That is, by providing this stopper 10, the motion of rubbing the floor surface when kicking the leg backward during walking can be accurately reproduced. The installation position of the stopper 10 is determined by the positional relationship of each part of the testing machine, but is preferably a position immediately after the second part 3b corresponding to the toe of the foot is separated from the test body.

  In the present embodiment, the case where the disc 12 is used to drive the rod 5 has been shown. However, as other embodiments, a crank (not shown) is used for the drive shaft 4 or a cam (not shown). Can also be adopted. However, since these embodiments are substantially the same as the present embodiment described so far, detailed description is omitted.

  Next, the flooring test method of the present invention using the testing machine configured as described above will be described.

  In the floor material 2 testing method of the present invention, first, a floor material 2 to be a test body is placed on a support base 1. At this time, even if the contact member 3 swings back and forth, the front end and the rear end thereof are prevented from protruding from the surface of the flooring 2. In an actual use mode, since dirt substances and solids are attached to the shoe sole, dirt substances (not shown) are sprayed in advance on the surface of the flooring 2 in order to reproduce a similar situation. Preferably, if the test time (the number of walks) is long, a dirt substance may be supplied as needed.

  The soiling material sprayed on the surface of the flooring 2 is not particularly limited. To evaluate the soiling resistance, abrasion resistance, and scratch resistance of the flooring 2, peat moss, Portland cement, It is preferable to use a mixture of clay soil, diatomaceous earth, carbon black, iron oxide for ferrite, Nujol, and water according to a blending ratio according to JIS L1023. At this time, a particulate matter such as silica sand may be added as appropriate to increase the wear factor on the specimen.

  As described above, when the flooring 2 is placed on the support base 1, the drive shaft 4 is rotated by the drive source. In the present embodiment, as shown in FIG. 1, the support base 1 is not pulled forward by the tension spring 1 c (that is, the support base 1 is not slid rearward), and the contact member 3 The drive shaft 4 is rotated in a state in which the rear end portion is in contact with the surface of the flooring 2 (a state in which the legs are stepped on and the heel is in contact with the flooring 2). When the drive shaft 4 rotates, the disc 12 attached to the tip of the drive shaft 4 also rotates with it, and the locking portion 8 provided on the outer peripheral edge of the disc 12 is orthogonal to the drive shaft 4. While maintaining a certain distance, the vehicle starts turning clockwise about the drive shaft 4.

  Since the locking portion 8 is engaged with a long hole 9 provided in the upper end portion of the rod 5, the locking portion 8 turns while moving inside the long hole 9. Since the positions of the drive shaft 4 and the pivot shaft 7 are fixed, when the locking portion 8 turns, the guide portion 6 that guides the movement of the rod 5 swings around the pivot shaft 7, and accordingly The rod 5 and the contact member 3 also swing.

  As described above, when the locking portion 8 turns, as shown in FIG. 2, the rod 5 comes upright when the locking portion 8 turns to a position in the direction of approximately 7 o'clock to 8 o'clock. At this time, the contact member 3 is in a state where substantially the entire lower surface is in contact with the surface of the flooring 2, and the movement of the contact member 3 as it moves rearward to just below the pivot shaft 7. The support 1 also slides backward as much as the distance. And the load addition means 11 (compression spring) is compressed, Thereby, the load is added to the flooring 2 from upper direction. Thereby, in an actual human walk, an intermediate movement from the stepping out of the leg to the kicking out of the leg is reproduced.

  As shown in FIG. 3, when the locking portion 8 turns to a position in the direction of approximately 9 o'clock to 10 o'clock, the contact member 3 moves backward most, that is, in human walking, the leg is moved backward. It becomes the state when kicking out. As the abutting member 3 moves rearward, the support base 1 also slides backward. At this time, the protruding portion 1a of the support base 1 hits the stopper 10, so that the support base 1 further moves backward. Never slide. Further, as the rod 5 is tilted, the second portion 3b rotates about the first variable portion 3c with respect to the first portion 3a of the contact member 3, and the rod 5 The contact member 3 rotates around the second variable portion 3d. Accordingly, only the second portion 3 b of the contact member 3 comes into contact with the surface of the flooring 2 in a state where the locking portion 8 is turned to a position in the direction of approximately 9 o'clock to 10 o'clock. In this way, by configuring the contact member 3 from a plurality of portions (3a, 3b) connected so that the connection angle is variable, it is possible to faithfully reproduce the movement of the human toe and ankle.

  In FIG. 4, the contact member 3 is separated from the floor material 2. At this time, the locking portion 8 is swung to a position in the approximately 12:00 direction, and the contact member 3 is separated from the floor material 2 when the rod 5 is pulled upward. When the contact member 3 is separated from the floor material 2, the support base 1 from which the load from above is lost is pulled forward by the tension spring 1c and slides to the original position. And if the latching | locking part 8 turns to the position of a substantially 4 o'clock direction, the contact member 3, the rod 5, and the guide part 6 will return to the state shown in FIG.

  As described above, each time the drive shaft 4 makes one rotation, the movement of stepping on the human leg shown in FIG. 1, the movement of stroking the human leg shown in FIG. 2, the movement of kicking out the human leg shown in FIG. The movement of lifting the human leg shown in FIG. 4 is faithfully reproduced. Therefore, by repeating this, the contact member 3 is brought into contact with the surface of the flooring 2 a plurality of times while making a movement similar to the behavior of the legs during walking, and then various changes in the flooring 2 are evaluated. Thus, under substantially the same conditions as the actual use mode, the floor material 2 can be subjected to multiple tests for evaluation of stain resistance, wear resistance, scratch resistance, sag, and the like.

  The method of evaluating the flooring 2 is performed by visually confirming changes in the degree and thickness of the flooring 2 due to dirt, abrasion, and scratches. In addition to this, surface property changes such as color difference, gloss difference and surface flaw depth before and after the test, mass change, thickness change, peeling state between floor material layers (the floor material 2 as a test specimen is It is preferable to evaluate by comparing a case where it is formed of a plurality of layers. Furthermore, by confirming the sticking state between the back surface of the flooring material 2 and the surface of the support base 1 (when the flooring material 2 is stuck to the support base 1 with the sticking agent), the flooring material 2 and the sticking agent It is also possible to evaluate the sticking property. In the present invention, since the support base 1 slides in the front-rear direction, it is possible to reproduce even the frictional motion in which the contact member 3 (sole) rubs the surface of the flooring 2. Therefore, this test method is excellent for evaluating the surface performance of the flooring 2 and is particularly suitable for evaluating the contamination of the surface of the flooring 2.
