The present invention relates to an open and close repeatability test device of the swing door set, and more particularly, to improve the reliability of the test by improving the conventional formal test device so that the actual situation when a person opens and closes the door actively reflected in the open and close repeatability test. The present invention relates to a test device for opening and closing repeatability of a set of swing doors.

For swing door sets, Korean Industrial Standard KS F 2297 (General Rules for the Performance Test Method of Windows) is required to test the torsional strength, the vertical load strength, the opening and closing force, the opening and closing repeatability, and the impact resistance. Industry standard KS F 2632 stipulates in accordance with the test method for repetition of opening and closing of door sets.

The standard of the test apparatus illustrated in the opening and closing repeatability test method of the door set specified in the Korean Industrial Standards is shown in FIG. 1. As shown in Fig. 1, in the conventional open / close repeatability test apparatus, a drive source composed of a motor, a reducer, and the like rotates the drive shaft, and the arm opens and closes the door by the drive shaft. In this open / close repeatability test, the opening and closing angle of the door is made in the range of 80 ° ± 5 °, and the displacement of the door is recorded and evaluated as the opening and closing proceeds. The number of opening / closing is required to have no abnormality in opening and closing and no trouble in use after 15 times, total 100,000 times in one minute in KS F 3109.

As mentioned above, the repetition test for opening and closing specified in the Korean Industrial Standard is to measure the displacement as the door is repeatedly opened and closed, and to determine whether there is no abnormality in the opening and closing. Therefore, it is an important guideline for judging the durability of the hinge that hinges the door. will be. This is because if the durability of the hinge occurs due to the repeated opening and closing, the hinge and the door frame and the door will be loosely coupled, causing a gap to increase the displacement, or opening and closing the door will not be performed smoothly. .

However, in the above-mentioned Korean Industrial Standard KS F 2632, there is no provision that the door should be closed in the door frame during the opening and closing repeatability test. In other words, when closing the door there is no statement that the door should touch the door frame. Therefore, in the past, the door was opened again before the door touched the door frame, and in most cases, the test was performed far from the actual usage of the door. Another reason is that in Korean Industrial Standard [Section 9.5.3 d) of KS F 3109d], 'When the door is closed, do not push the door with the arm of the test apparatus shown in Fig. 6. Cancer, etc., must be spaced apart from the door before it can fit into the frame. ' In other words, it is difficult to implement a device that will be able to separate (drop) the arm from the door 'before the door closes into the door frame (before it is fully closed or touched)' and even if the door is opened again before the door reaches the door frame, KS This does not violate the requirements of F 2632, because there was no need to develop a test system that would allow the door to contact the door frame at a higher cost.

When the door is actually opened and closed, the door naturally hits the door frame, and the impact of the impact is continuously and repeatedly acted on the door set such as the hinge, and thus the performance deterioration (durability deterioration) occurs due to repeated opening and closing. This is the same as the problem of performance deterioration to be measured in the door set opening and closing repetition test prescribed in the Korean Industrial Standards, and the provisions of the Korean Industrial Standards contain the purpose of durability test in case of using the actual door.

However, according to the conventional test method, as described above, only the swing motion of the door is implemented and measured, and the situation when the door is used in real life is not properly reflected in the test, so the opening and closing is repeated 100,000 times. Even so, the performance change (degradation) of a statement set cannot be evaluated properly. Therefore, the problem that the door set of poor quality passes, the purpose of the door set opening and closing repetition test prescribed by the Korean Industrial Standards is impaired, and the reliability of the test cannot be guaranteed.

The present invention was developed to solve the problems of the conventional door set opening and closing repeatability test device as described above, the door and the door frame is completely closed so that the actual situation when using the door is reflected in the opening and closing repeatability test By providing maximum access to the provision that the arm should be spaced apart from the door before it is fitted into the door frame, it is possible to measure the repeatability of the door set according to the original intent of the Korean Industrial Standards and to ensure the reliability of the test. It is an object of the present invention to provide a test device for opening and closing repeatability of a set of swing doors.

In order to achieve the above object, in the present invention, the apparatus for testing the opening and closing repeatability of the swing door set connected to the door frame by a hinge rotatably, comprising: a test body mounting frame for fixing the door frame; An arm having a rotational angle to rotate the door in an open direction and a close direction by a driving source, and to rotate the door further above a point where the door contacts the door frame when the door is rotated in the close direction; And a connecting mechanism connecting the arm and the door, wherein the connecting mechanism includes a rod having one end connected to the arm and having a free end thereof penetrating the handle installation hole of the door, and a free end of the rod. And a stopper for contacting the inner surface of the door to transmit the pulling force to the door when the rod is pulled to open the door, and disposed between the rod and the outer surface of the door to separate the rod and the door from each other. It provides an elastic pressing force to be made, and the opening and closing repeatability test apparatus of the swing door set is provided, including a cushioning member that is compressed by a force for closing the door from the time when the door is in contact with the door frame.

The test apparatus of the present invention is connected to the door frame by having a configuration in which the arm and the door, the rod and the shock absorbing member, etc. are connected to each other and the door is closed with only a small elastic force of the shock absorbing member when the door is closed. The test device conforms to the Korean Industrial Standards, which improves the reliability of the test and allows the arm to be spaced apart from the door before the door is secured to the door. Enables implementation of

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

Figure 2 is a plan sectional view showing the overall structure of the test apparatus according to the first embodiment of the present invention.

As illustrated in FIG. 2, a door set having a form in which the door 10 is rotatably fixed to the door frame 30 by a hinge 20 is prepared. The opening and closing repeatability test apparatus 100a of the swinging door set of the present invention for testing the opening and closing repeatability of the door set includes: opening and closing the test body mounting frame 110 and the door 10 for fixing the door frame 30. Arm (200) for and includes a connection mechanism (300a) for connecting the arm 200 and the door (10).

Specifically, the test specimen mounting frame 110 may include a frame 111 on which the door frame 30 is seated, and a clamp 112 for fixing the door frame 30 seated on the frame 111. .

The arm 200 rotates the door 10 in the opening direction and the closing direction by a drive source (not shown). To this end, one end of the arm 200 is connected to the drive shaft 120 is rotated by the drive source. The drive shaft 120 is rotatably installed on the support block 121 installed on one side of the frame 111. As will be described in detail later, the opening and closing angle of the door 10 according to the present invention is basically set to 80 ° ± 5 °, the angle specified in the Korean Industrial Standards, but the rotation angle of the arm 200 is larger than this . That is, when the arm 200 rotates in the closing direction, the door 10 is completely closed to have a rotational angle to rotate more than the point of contact with the door frame 30.

The connecting mechanism 300a connects the arm 200 and the door 10. In addition, the connection mechanism 300a, as intended in the present invention, acts to close the door 10 and the door frame 30 completely so that the situation when the door is actually used to actively reflect the opening and closing repeatability test. Along with the role to play, it serves to conform to the provisions of the Korean Industrial Standards that the arm 200 should be spaced apart from the door before the door 10 is tightly fitted to the door frame 30 (closely closed).

3 is an enlarged view of a main part showing a state at the time when the door 10 is closed and contacts the door frame 30 in FIG. 2. As shown in FIG. 3, the connection mechanism 300a includes a rod 310 having one end connected to the arm 200 and a free end thereof penetrating the handle installation hole 11 of the door 10. And a stopper 320a coupled to the free end of the rod 310. The stopper 320a has a diameter larger than that of the handle mounting hole 11, so as to contact the inner surface 10a of the door 10 when the rod 310 is pulled to open the door 10. The rod 310 serves to open the door 10 by transmitting the pull force to the door 10. In this embodiment, the rod 310 and the stopper 320a take the form of 'bolts' and 'nuts' that are screwed together. However, it is not limited thereto.

In addition, a buffer member 330 is interposed between the rod 310 and the outer surface 10b of the door 10. The shock absorbing member 330 provides an elastic pressing force to space the rod 310 and the door 10 apart from each other, ie, to drop the rod 310 and the door 10 apart from each other. In this embodiment, the buffer member 330 is inserted into the rod 310 in the form of a 'compression coil spring', but is not necessarily limited to such a compression coil spring. A support plate 331 is interposed between the outer surface 10b of the door 10 and the buffer member 330 to stably support the buffer member 330.

On the other hand, in order to comply with the relative displacement of the arm 200 and the rod 310, the movable block 340 is coupled to the arm 200 to be slidable, the movable block 340 to the The ends of the rod 310 are coupled to slide and angularly. To this end, in the present embodiment, the hole of the rod 310 coupled to the arm 200 is configured in the form of an expansion-type insertion hole 341 widening from the middle to both ends. According to this configuration, the movable block 340 can freely slide with respect to the arm 200 in accordance with the rotation of the arm 200, the rod 310 and the movable block 340 is freely angled It can move, and the opening and closing operation of the door 10 by the connection mechanism 300a is made smoothly.

FIG. 4 is an enlarged view of a main part showing a state in which the force 10 is further applied in the closing direction from the time when the door 10 is completely closed and contacted with the door frame 30 in FIG. 3. In performing the actual test using the opening and closing repeatability test apparatus 100a of the swing door set of the present invention configured as described above, as shown in FIG. 4, when the shock absorbing member 330 closes the door 10, When the arm 10 is further rotated after the point of contact of the door 10 with the door frame 30, the rod 10 is compressed by the closing force of the door 10, thereby allowing the rod 310 to move further in the closing direction. In addition, the inertia of the arm 200 is attenuated so as to be stably stopped. In this case, since the force of the arm 200 is transmitted to the door 10 through the shock absorbing member 330, a force greater than the elastic force (compression force) of the shock absorbing member 330 may be transmitted to the door 10. There is no. At this time, if the elastic force of the shock absorbing member 330 is set as small as possible so as not to be compressed when pushing the door 10, the elastic force of the shock absorbing member 330 is the weight of the door 10 and the door 10 Compared to this closing moment of inertia, it is just a negligible degree. That is, when the door 10 hits the door frame 30 (when in contact), the door 10 is to be hit in an almost free state in which only the elastic force of the shock absorbing member 330 is negligible. Since only the elastic force of the shock absorbing member 330 acts even after being bumped, in the Korean Industrial Standard [Section 9.5.3 d) of KS F 3109d], when the door is closed, the door is opened with a ~ arm. However, it is possible to satisfy the rule, "The cancer should be spaced apart from the door before the door fits in the frame."

5 to 9 show a test apparatus according to a second embodiment of the present invention. The test apparatus 100b according to the present embodiment differs only in the configuration of the test apparatus 100a and the connection mechanism 300b in the above-described first embodiment, and the rest of the configuration is the same. Therefore, the same reference numerals are assigned to the same components as those in the first embodiment, and repeated description thereof will be omitted.

In the test apparatus 100b according to the present embodiment, a structurally stable coupling mechanism 300b is disclosed. First, as shown in Figs. 5 and 6, the connecting mechanism 300b according to the present embodiment is a hollow screw shaft (3) in the rod 310 of the connecting mechanism 300a according to the first embodiment. 350) is formed in a combined form. The screw shaft 350 is provided with the screw in the outer side, and the hollow part 351 is formed in the inside. The screw shaft 350 is screwed to the door 10 through the handle installation hole 11 of the door 10.

The rod 310 penetrates through the hollow portion 351 of the screw shaft 350 in a state capable of sliding. That is, in the first embodiment, the rod 310 is directly fixed to the door 10 by penetrating the handle installation hole 11 of the door 10, but in this embodiment, the screw shaft ( 350 is fixed to the door 10 through the handle mounting hole 11, the rod 310 is fixed to the screw shaft 350 through the screw shaft 350.

Therefore, in the above-described first embodiment, the stopper 320a having the shape of a nut is deformed into a stopper 320b having a shape such as a bolt and coupled to the free end of the rod 310 so that In contact with the end. This stop 320b is in contact with the end of the screw shaft 350 when the rod 310 is pulled to open the door 100, and thus the force pulling the rod 310 is It serves to be transmitted to the door 10 via the screw shaft 350.

In addition, the shock absorbing member 330 is disposed between the rod 310 and the screw shaft 350 to provide an elastic pressing force to space the rod 310 and the screw shaft 350 from each other. The 310 and the door 10 are provided to separate the power from each other.

The screw shaft 350 is coupled to the fastener 360 in the inner and outer directions of the door 10, respectively. Loosening both fasteners 360 on both sides to relax the inner surface 10a and outer surface 10b of the door 10 allows the screw shaft 350 to be freed from the restraint to adjust the length, and both fasteners 360 ) Is tightened to closely contact the inner surface 10a and the outer surface 10b of the door 10 so that the screw shaft 350 is firmly fixed to the door 350. Between the fastener 360 and the door 10, a support plate 370 may be installed to stably seat the fastener 360.

Thus, the test apparatus 100b according to the second embodiment is structurally because the rod 310 is installed on the door 10 via the screw shaft 350 so that the rod 310 moves within the screw shaft 350. A very stable test apparatus can be implemented, and the rod 310 can operate while being guided by the screw shaft 350 to implement a test apparatus that can be opened and closed smoothly. In addition, the length of the screw shaft 350 can be easily adjusted by the fastener 360, and after the adjustment, the length of the screw shaft 350 can be firmly fixed to the door 10.

On the other hand, Figure 7 to Figure 9 is a view showing a state in which the door is opened and closed in the test apparatus according to the present invention. 7 to 9 illustrate the opening and closing operation of the test apparatus 100b according to the second embodiment of the present invention, but the opening and closing operation of the test apparatus 100a according to the first embodiment is also the same.

First, as shown in FIG. 7, the opening and closing angle of the door 10 is preferably set to 80 ° ± 5 °, which is an angle defined by the Korean Industrial Standard. This can be realized by setting an operating angle of a drive source (not shown) for rotating the drive shaft 120. For example, when using a step motor as a drive source, what is necessary is just to set the rotation angle of a step motor to the said angle range. However, in the present invention, since the arm 200 needs to be rotated more even after the door 10 is closed, the rotation angle of the drive source, that is, the rotation angle of the drive shaft 120 should be set to exceed 85 °.

When the drive shaft 120 is rotated in the opening direction (counterclockwise direction) by the driving source, the arm 200 rotates in the opening direction to pull the rod 310 (see FIG. 5) of the coupling mechanism 300b, and the rod 310 pulls open the door 10. The operation process of opening the door 10 by pulling the rod 310 has already been described in detail above.

Subsequently, when the drive shaft 120 is rotated in the closing direction (clockwise in the drawing), as shown in FIG. 8, the door 10 is closed to the door frame 30. In this process, the relative displacement of the rod 310 and the arm 200, the sliding motion of the moving block 340 along the arm 200 and the relative movement of the rod 310 and the moving block 340 relative to each other It is absorbed smoothly by the action. When the door 10 is completely closed by the door frame 30, the door 10 will hit the door frame 30 similarly to when a real person closes a door. As described above, when the door 10 hits the door frame 30, the force transmitted to the door 10 by the arm 200 is only the elastic force of the very weak buffer member 330. Therefore, the door 10 hits the door frame 30 in a free state with little force from the arm 200. Also accordingly, the aspect of using the door in real life is directly reflected in the test, thereby improving the reliability of the test result.

As shown in FIG. 9, after the point at which the door 10 hits the door frame 30, the arm 200 pivots further in the closing direction by the cushioning angle to further push the rod 310 in the closing direction by the cushioning length. Push. Then, the shock absorbing member 330 is compressed by the rod 310 to absorb the rotational inertia of the arm 200 so that the rotation of the arm 200 is slowly and stably decelerated and then stopped.

Then, when the arm 200 is rotated counterclockwise again to open the door 10, the rod 310, which has been further entered into the door 10, is pulled out. In addition, as the rod 310 is pulled, the buffer member 330, which has been compressed, also returns to its original shape. Then, the stopper 320b (see FIG. 5) installed at the end of the rod 310 to be pulled opens the door 10 again.

As described above, according to the opening and closing repetition test apparatus of the present invention, by having a configuration for connecting the arm and the door through a connecting mechanism consisting of a rod and a cushioning member, the door is closed to the door frame so that the door is actually closed The use situation can be reflected in the open / close repeatability test, which can meet the intent of the open / close repeatability test of the swing door specified in the Korean Industrial Standard, and improve the reliability of the test.

In addition, when the door is closed, the door is pushed only by the small elastic force of the cushioning member, so that a test apparatus conforming to the Korean Industrial Standard that the arm should be separated from the door before the door is fastened to the door frame can be realized. Become.
