Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stopper mechanism for a sliding door that is guided by a sill and a duck.
[0002]
[Prior art]
Conventionally, as a stopper structure for a sliding door that is guided by a sill and a duck, for example, a structure having a gently curved spring piece convex downward is attached to the bottom of a ditch groove and used. . When the sliding door moves and its upper end surface comes into contact with the convex curved surface of the stopper, the stopper is elastically deformed and acts to stop the sliding door by a reaction force proportional to the magnitude of the deformation. Moreover, the same thing or another shape thing may be attached and used for the bottom face of the groove | channel of a sill instead of a duck.
[0003]
[Problems to be solved by the invention]
However, the stop position of any of the above conventional stoppers changes due to the force for moving the sliding door. That is, there is a problem that if the force to be moved is weak, it stops at the front, and if it is strong, it stops at the back side or exceeds the stopper.
[0004]
Also, in the case of so-called sliding doors where two sliding doors are installed in the same groove of the sill, if the two sliding doors are closed separately, the contact surfaces of both may not come to the center, Attempting to close the sliding doors at the same time has a problem that the closing force is too strong, and a loud collision noise is generated at the time of contact.
In addition, even if there is a pillar on either side, if the sliding door is closed so as to abut the pillar, the force to apply is too strong and there is a loud collision sound, and if it is a sliding door, only one sliding door In this movement, there is a problem that the side surfaces of the two sliding doors do not readily coincide with each other and a gap is generated.
[0005]
Accordingly, an object of the present invention is to provide a sliding door stopper mechanism in which the stop position is constant regardless of the strength of the force to be moved, which eliminates the drawbacks of the conventional example.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the sliding door stopper mechanism according to the first aspect of the present invention has a spring mechanism (S) at a corner side position from the wheel (55) attached to the lower end surface of the sliding door (10). Together with a vertical leg (V) and a wheel (50) which are pushed downward so as to always protrude downward from the lower end surface of the sliding door (10) and retreat upward when pushed from below. A vertical wall (W) that is formed on an extension line of a horizontal groove (HG) that supports and guides the vertical leg (V) from below and prevents the vertical vertical leg (V) from abutting against the side surface of the vertical leg (V). And a sloping groove (SG) formed so as to incline downward from the horizontal groove (HG) toward the vertical wall (W), and the vertical leg (V) ) Slides on the bottom of the horizontal groove (HG) and inclined groove (SG) , Characterized in that by lifting-advance and retreat to follow it, when said vertical leg (V) is in contact with the vertical wall (W), that the wheel (55) to bear on the horizontal groove (HG) And
[0007]
The invention according to claim 2 is characterized in that a leg ring (C) is rotatably attached to the lower end of the vertical leg (V) according to the invention of claim 1.
[0008]
Furthermore, the invention according to claim 3 is a round recess (H) for receiving and holding the tip of the vertical leg (V) at the lowest position of the inclined groove (SG), which is the base of the vertical wall (W). The sliding door stopper mechanism according to claim 1, wherein the sliding door stopper mechanism is formed.
[0009]
The symbols in parentheses described in the means for solving the above-described problems correspond to the symbols described in the drawings and embodiments of the invention described later.
[0010]
According to the first aspect of the present invention, when the sliding door is pushed or pulled, the wheel moves by being guided by the horizontal groove or the inclined groove of the sill and rolling. At that time, the vertical leg pushed downward by the spring mechanism slides on the bottom surface of the horizontal groove and the inclined groove, and ascends / descends / retreats, but when it contacts the vertical wall at the end of the inclined groove, Progress is blocked and stops at that position reliably. At this time, since the vertical leg is positioned at the lowest part of the inclined groove, it protrudes sufficiently downward. Therefore, the stop position is not changed by the force for moving the sliding door, but stops at a fixed position.
[0011]
Therefore, the two sliding doors such as the sliding doors are stopped without a gap between the side surfaces. In addition, even when there are columns at the end of a sliding door or a sill where the sliding doors move in the same groove, the problem that the sliding doors collide with each other and the sliding doors generate a loud collision sound is solved.
[0012]
According to the second aspect of the present invention, the leg ring rotatably attached to the lower end of the vertical leg rolls on the horizontal groove and the inclined groove. Not only the ring but also the horizontal and inclined grooves are less worn.
[0013]
Further, according to the invention described in claim 3, since the round recess for receiving and holding the tip of the vertical leg is formed at the lowest position of the inclined groove, which is the base of the vertical wall, The reaction caused by the contact can be suppressed, and the sliding door can be stopped more stably.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
A stopper mechanism for a sliding door according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a vertical sectional view showing a stopper mechanism for a sliding door according to an embodiment of the present invention, and FIG. 2 is a vertical sectional view showing another embodiment.
The sliding door stopper mechanism according to the embodiment of the present invention is composed of a vertical leg V and a sill piece 22 which will be described later, and the vertical leg V is formed at a position near the corner portion of the lower end surface of the sliding door 10. It is attached inside.
[0015]
The vertical leg V faces downward so that the spring mechanism S always projects downward from the lower end surface of the sliding door 10 to the corner side end of the mounting seat 51 to which the wheel 55 attached to the lower end surface of the sliding door 10 is pivotally attached. It is attached so as to be pushed back and retreat upward when pushed from below.
Further, the sill piece 22 supports the vertical leg V together with the wheel 55 from below, and a vertical wall W that prevents the vertical vertical leg V from abutting on the side surface of the vertical leg V on an extension line of the horizontal groove HG to guide and guide the vertical leg V. The sill 20 is composed of an inclined groove SG formed so as to be inclined downward from the horizontal groove HG toward the vertical wall W, and combined with the sill piece 21 of the horizontal groove HG.
[0016]
The sill 20 may be integrally manufactured, but a sill piece 22 having an inclined groove SG having a vertical wall W that prevents the vertical leg V from advancing at the end is prepared separately, and an appropriate length is obtained at the construction site. It may be configured to be connected to the sill piece 21 having only the horizontal groove HG cut into two or inserted between the sill pieces 21, 21.
In addition, it is preferable that the round hollow H which receives and hold | maintains the front-end | tip of the vertical leg V is formed in the root of the vertical wall W of the sill piece 22.
[0017]
According to the sliding door stopper mechanism configured as described above, when the sliding door 10 is pushed or pulled, the wheel 55 moves by being guided by the horizontal groove HG or the inclined groove SG of the sill 20 and rolling. . At that time, the vertical leg V pushed downward by the spring mechanism S slides on the bottom surface of the horizontal groove HG and the inclined groove SG, and moves up and down and retreats accordingly.
When the vertical leg V reaches and abuts the vertical wall W at the end of the inclined groove SG, its progress is blocked, and it is reliably stopped at that position, and is stably held by the round recess H. At this time, since the vertical leg V is positioned at the lowest part of the inclined groove SG, it protrudes sufficiently downward. Therefore, the stop position is not changed by the force to move the sliding door 10 and stops at a fixed position.
[0018]
Next, the case where this invention is applied with respect to a sliding door is demonstrated. In this case, a sill piece 30 as shown in FIG. 2 is mounted between the sill pieces 21 and 21 each having the horizontal groove HG. This is a shape in which the surfaces on the vertical wall W side of the two sill pieces 22 having the inclined grooves SG are joined to each other, and a pair of vertical walls W and W, depressions H and H, both sides at the center portion. Are provided with inclined grooves SG, SG which are gently inclined downward toward the center.
[0019]
A vertical leg V having the same configuration as described above is provided on the corner side of the lower surface of each sliding door 10 on the side in contact with each other. In this case, as a matter of course, the vertical legs V on the side of the sliding doors 10 and 10 are matched with the positions of the vertical walls W and W of the sill piece 30 so that both side surfaces abut at the respective stopping positions of the sliding doors 10 and 10. , V need to be adjusted.
[0020]
According to this, even if only one of the sliding doors 10 is closed, as described above, since the stopper always stops at a predetermined position, the side surfaces of the sliding doors 10 and 10 do not coincide with each other as in the past. All occurrences of loud collision noise are eliminated. In addition, even when there is a pillar at the end of the sill with respect to the sliding door, the sliding door stops at a predetermined position by combining the vertical leg V and the sill piece 22 regardless of how the force is applied. Therefore, all the problems that have conventionally occurred are solved.
[0021]
FIGS. 3 to 5 show double doors with two doors, three sliding doors, and a single door. As shown in FIG. 3, a sill piece 30 having symmetrical inclined grooves and vertical walls on both sides is arranged at the center in the same manner as in FIG. Moreover, as shown in FIG. 4, with respect to the sliding doors 10 and 10 on both sides of the three-way sliding door, it is close to the pillars 60 and 60, and with respect to the central sliding door 10, on either side. A threshold piece 22 is arranged. Furthermore, as shown in FIG. 5, the sill piece 22 is arrange | positioned near the both pillars 60 and 60 with respect to the one retractable door, respectively.
[0022]
Furthermore, as shown in FIG. 6, the leg ring C is rotatably attached to the lower end of the vertical leg V because the leg ring C rolls on the horizontal groove HG and the inclined groove SG. This is more preferable because the resistance when hitting is reduced and the wear of the horizontal groove HG and the inclined groove SG as well as the leg ring C is reduced.
[0023]
【The invention's effect】
According to the first aspect of the present invention, the stop position is not changed by the force to move the sliding door, and the stop position is stopped. Therefore, each sliding door is stopped without a gap between the side surfaces of two sliding doors such as sliding doors. Moreover, even if there is a column at the end of the sliding door or the sill where the sliding doors move in the same groove, the problem that the sliding doors collide with each other and the column and the sliding door emit a loud collision sound is solved.
[0024]
According to the second aspect of the present invention, the leg ring rotatably attached to the lower end of the vertical leg rolls on the horizontal groove and the inclined groove. Not only the ring but also the horizontal and inclined grooves are less worn.
[0025]
Further, according to the invention described in claim 3, since the round recess for receiving and holding the tip of the vertical leg is formed at the lowest position of the inclined groove, which is the base of the vertical wall, The reaction caused by the contact can be suppressed, and the sliding door can be stopped more stably.
