Description

  The present invention relates to a mounting structure of a buffer mechanism in a sliding door for incorporating a buffer mechanism that slowly decelerates the sliding door and stops it smoothly.

  Sliding doors that open and close by sliding the opening of the building in the horizontal direction have a problem that depending on the momentum of closing, the door collides with the opening frame and generates an impact sound. To solve this problem, rubber A door stop made of foamed resin or the like is provided at the door tip.

  However, because the momentum at which the sliding door closes cannot be attenuated, the sliding door may bounce off the opening frame and be unable to close, so the buffer that slowly decelerates the sliding door near the stop position and stops it smoothly. It has been proposed by the present applicant to incorporate the mechanism into a sliding door (Patent Document 1).

  As shown in FIG. 4, the buffer mechanism described in Patent Document 1 is disposed on the buffer mechanism body 2 disposed on the sliding door 1 side and on the side of the head 4 attached to the upper end of the opening 3 of the building. It is comprised from the buffer mechanism holder 5. FIG.

  As shown in FIGS. 5 <a> and <b>, the shock-absorbing mechanism body 2 has a roller shaft 7 having a roller 6 at the tip so that it can swing in the front-rear direction about a pivot 8 provided at the lower end. It is arranged and supported by the absorber 9.

  As shown in FIGS. 6 <a> and <b>, the buffer mechanism receiving member 5 is disposed in the stop position of the sliding door 1 and protrudes downward, is adjacent to the stopper 10, and is in the sliding direction of the sliding door 1. A guide groove 11 disposed on the rear side and a slope portion 12 adjacent to the guide groove 11 and disposed rearward in the sliding direction of the sliding door 1 and projecting downward as approaching the guide groove 11 are provided.

  As shown in FIG. 4, such a buffer mechanism is formed in the head 4 at the end of the head 4 so that the stopper 10 is disposed at the stop position of the sliding door 1. The buffer mechanism main body 2 is disposed at the upper end of the sliding door 1 on the door end side. The upper end of the sliding door 1 located at the door end is cut out to form a cutout 13, and the roller shaft 7 together with the roller 6 is housed in the cutout 13.

When closing the sliding door 1, the roller 6 comes into contact with the slope surface of the slope portion 12 on the near side from the fully closed position of the sliding door 1, and as the sliding door 1 closes, the roller 6 moves along the slope surface and pivots 8. And the roller shaft 7 is in the lowest state shown in FIG. 7 <a>. When the sliding door 1 is further closed from this state, the roller 6 passes over the slope portion 12 and comes into contact with the stopper 10, and then the roller shaft 7 rotates backward about the pivot 8 as shown in FIG. The roller 6 is fitted into the guide groove 11 and is in the uppermost state. Then, as shown in FIG. 7 <c>, the roller shaft 7 is further rotated rearward, sliding door by swinging in the longitudinal direction of the series of roller shaft 7, the upcoming opening frame 14 shown in FIG. 4 1 is sufficiently decelerated, and the sliding door 1 can be closed smoothly.

Therefore, even if the sliding door 1 closes vigorously, it is slowly decelerated near the fully closed position, stops smoothly, and does not bounce. Naturally, no impact sound is generated.

  Thus, although it is the buffer mechanism which can decelerate the sliding door 1 slowly and can be closed smoothly, the following improvements were found by subsequent examination.

  As shown in FIG. 4, the buffer mechanism main body 2 is disposed on the door end side of the sliding door 1, and the buffer mechanism receiver 5 is disposed at the terminal end of the head 4 corresponding to this, so that the roller 6 When the roller 6 comes into contact with the slope surface of the slope portion 12, the roller 6 may collide with the slope surface of the slope portion 12 depending on the momentum of closing the sliding door 1, and the roller 6 rebounds due to the impact, as shown in FIG. Moreover, the door end side of the sliding door 1 may jump up. In the case where there is a dimensional error in the head 4 or the opening frame 14 or the like and the sliding door 1 itself in association with the jumping of the sliding door 1 on the front end side, specifically, the height of the opening frame 14 is too high. When the sliding door 1 is too low, or when the construction condition is poor, specifically, when the duck 4 is constructed in an arch shape, the sliding door 1 is detached from the duck 4 or the like. There is a possibility of falling.

  The present invention has been made in view of the circumstances as described above, and has a shock absorber mounting structure in a sliding door that can be surely slowed down slowly and stopped smoothly without causing the sliding door to spring up. The issue is to provide.

  The present invention has the following features in order to solve the above problems.

In the first invention, the buffer mechanism main body having the buffer portion is incorporated in the rear end upper portion located on the rear side in the sliding direction of the sliding door, and the sliding movement of the sliding door is decelerated by contact with the buffer portion of the buffer mechanism main body, The buffer mechanism receiver to be stopped is disposed in the duck in the position facing the buffer mechanism body on the door bottom side of the sliding door that is in the fully closed position, and when the sliding door is closed, the sliding door that has been slid to the fully closed position The buffer part of the buffer mechanism body incorporated in the upper part of the rear end contacts the buffer mechanism receiver, and the sliding movement of the sliding door is decelerated and stopped .

  In a second aspect based on the first aspect, the shock absorber receiving member has a shock receiving portion protruding downward that can come into contact with the shock absorbing portion of the shock absorbing mechanism main body, and a lower notch is formed at the upper end of the sliding door over the entire width of the sliding door. A buffer portion of the buffer mechanism body is housed in the lower cutout portion, and the buffer receiver portion of the buffer mechanism receiver can enter the lower cutout portion of the upper end portion of the sliding door.

  According to a third aspect, in the second aspect, the shock absorber receiving member includes a stopper that protrudes downward disposed at the stop position of the sliding door, and a guide groove that is adjacent to the stopper and is disposed rearward in the sliding direction of the sliding door. And a slope portion as a buffer receiving portion, which is adjacent to the guide groove and is disposed rearward in the sliding direction of the sliding door and protrudes downward as the guide groove is approached. A roller shaft as a buffer portion provided at the tip with a roller that can contact the slope surface of the portion is disposed so as to be swingable in the front-rear direction around a pivot provided at the lower end portion, and supported by an absorber, The stopper and the slope portion of the buffer mechanism receiving member are characterized in that they can enter the lower notch portion at the upper end portion of the sliding door.

According to the first aspect of the present invention, the buffer mechanism main body having the buffer portion is incorporated in the rear end upper portion located on the rear side in the sliding direction of the sliding door, and the sliding door slides by contact with the buffer portion of the buffer mechanism main body. The buffer mechanism receiving member for decelerating and stopping is disposed on the door bottom side of the sliding door that is in the fully closed position and facing the buffer mechanism main body. Even if it collides with the buffer mechanism receiving member, the front side portion in the sliding direction of the sliding door becomes difficult to jump up, and the sliding door can be surely slowly decelerated and stopped smoothly.

  According to the second aspect of the invention, in addition to the effect of the first aspect, the shock absorber receiving member has a shock absorber receiving portion that protrudes downward so as to come into contact with the shock absorber of the shock absorber main body. The lower notch is formed over the entire width of the sliding door, the buffer part of the buffer mechanism body is housed in the lower notch, and the buffer receiver of the buffer mechanism receiver can enter the lower notch of the upper end of the sliding door. The buffer part and the buffer receiving part are in contact with each other without causing the buffer part of the buffer mechanism body to collide with the duck or the buffer receiving part of the buffer mechanism holder to collide with the upper end part of the sliding door. While the deceleration and stop are realized, the buffer receiving part can be supported by the left and right inner walls forming the lower notch, so there is a dimensional error in the duck, the opening frame, etc. and the sliding door itself, Bad Even tempering, that the sliding door is out of such lintel is almost no, there is no risk of a fall. Safety is improved.

  According to the third aspect of the invention, in addition to the effect of the second aspect of the invention, the shock absorber receiving member is disposed at the stop position of the sliding door and protrudes downward, adjacent to the stopper, and in the sliding direction of the sliding door. In the buffer mechanism main body, it is provided with a guide groove disposed at the rear, and a slope portion adjacent to the guide groove, disposed at the rear in the sliding direction of the sliding door, and projecting downward as it approaches the guide groove. A roller shaft as a buffer portion provided at the tip with a roller capable of contacting the slope surface of the slope portion of the buffer mechanism receiver is disposed so as to be swingable in the front-rear direction around a pivot provided at the lower end portion. At the same time, since it is supported by the absorber, the sliding movement of the sliding door can be decelerated and stopped more reliably.

  FIG. 1 and FIG. 2 are a perspective view and a side view of relevant parts showing an embodiment of a buffer mechanism mounting structure in a sliding door of the present invention, respectively.

  In the mounting structure of the buffer mechanism in the sliding door shown in FIGS. 1 and 2, the buffer mechanism shown in FIGS. 4 to 7 is employed as it is. That is, the buffer mechanism body 2 is disposed on the sliding door 1 side, the buffer mechanism receiver 5 is disposed on the side of the head 4 attached to the upper end of the opening 3 of the building, and the buffer mechanism body 2 and the buffer mechanism receiver 5 A buffer mechanism is configured. Since the configurations and structures of the buffer mechanism main body 2 and the buffer mechanism receiver 5 are the same, description thereof will be omitted.

  On the other hand, in the mounting structure of the buffer mechanism in the sliding door shown in FIGS. 1 and 2, the upper end portion of the sliding door 1 is notched downward over the entire width of the sliding door 1, and the upper end portion of the sliding door 1 has a substantially U-shaped cross section. A lower notch 15 is formed. The shock-absorbing mechanism body 2 is fitted into a recess formed in the upper end portion of the vertical rod 16 on the door butt side of the sliding door 1, and a flange portion 17 extending in the front and rear sides is brought into contact with the upper end surface of the vertical rod 16 to provide screws or the like. It is fixed by the fixing tool. A roller shaft 7 as a buffer portion provided in the buffer mechanism main body 2 is housed in the lower notch 15 together with the roller 6 at the tip. For this reason, the roller shaft 7 does not collide with the Kamoi 4.

  The buffer mechanism receiving member 5 that decelerates and stops the sliding movement of the sliding door 1 by contact with the buffer portion of the buffer mechanism main body 2 has the stopper 10 at the stop position of the sliding door 1 that is the fully closed position when the sliding door 1 closes the opening 3. Is arranged, that is, in a position facing the shock-absorbing mechanism main body 2, it is disposed in the rail groove 19 of the head 4 located on the door pocket 18 side. The rail groove 19 is a groove that guides the upper end of the sliding door 1 when the sliding door 1 is opened and closed. Although the shock absorber 5 protrudes downward from the rail groove 19, the upper notch of the sliding door 1 is formed with a lower notch 15 over the entire width of the sliding door 1, so that it contacts the stopper 10 and the roller shaft 7. The slope portion 12 as a possible buffer receiving portion can enter the lower cutout portion 15 when the sliding door 1 is closed without colliding with the upper end portion of the sliding door 1.

Therefore, in the mounting structure of the buffer mechanism in the sliding door shown in FIGS. 1 and 2, instead of the cushioning mechanism body 2 and the buffer mechanism receptacle 5 Gato destination side, Runode disposed door trailing side, the buffer mechanism body 2 3, even if the roller 6 provided for the collision may collide with the slope surface of the slope portion 12 of the shock absorber 5 due to the momentum of closing the sliding door 1, as shown in FIG. Thus, the sliding movement of the sliding door 1 is reduced and stopped. Moreover, since the stopper 10 and the slope portion 12 can be supported by the left and right inner side walls 20 shown in FIG. 1 that form the lower cutout portion 15, the dimensions of the duck 4, the opening frame 14, etc. and the sliding door 1 itself are out of order. Even if there is a problem or the construction condition is bad, the sliding door 1 is hardly detached from the Kamoi 4 or the like, and there is no risk of falling. Safety is improved. By the buffer mechanism body 2 and the buffer mechanism receiver 5, the sliding door 1 can be surely slowly decelerated and stopped smoothly.

  In the mounting structure of the buffer mechanism in the sliding door of the present invention, the buffer mechanism main body is incorporated in the upper part of the rear end located on the rear side in the sliding direction of the sliding door, so that the sliding door is slowly decelerated on the door pocket side when the sliding door is opened. In the case of stopping smoothly, the buffer mechanism main body can be incorporated into the upper part of the sliding door. In this case, the buffer mechanism supporter can be fixed to the rail groove of the duck near the opening on the door pocket side corresponding to the stop position of the sliding door. When the sliding door is opened, the sliding door is slowly decelerated and smoothly stopped, and the deceleration and the stopping can be surely performed.
