Description

[0001]
BACKGROUND OF THE INVENTION
The invention of this application relates to a door-car mounting structure. More specifically, the invention of the present application relates to a new door mounting structure that can be used for doors such as sliding doors equipped with door cars and can be easily mounted and set in height.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a door such as a sliding door, a door attached with a door that can slide in a horizontal direction is often used. FIGS. 6 (a) and 7 (a) each show an example of a door-to-door mounting structure for a door with a door, and an opening (2) is provided in the end (11) of the door (1). A door unit (3) comprising a door wheel (31) and a door wheel frame (32) is attached to the opening (2).
[0003]
[Problems to be solved by the invention]
However, in the conventional door mounting structure as described above, for example, as shown in FIG. 8, when the door (1) travels, the door wheel unit (3) is loosely attached by the load of the door (1), and the door wheel unit ( 3) There was a risk that it would shift itself. This can be a factor that hinders smooth running.
[0004]
Moreover, when the door (1) is built, it may be necessary to adjust the height according to the height of the building place, as shown in FIGS. 6 (b) and 7 (b). The complicated process of cutting the lower surface of the door (1) and further widening the opening (2) is necessary, or when the opening (2) cannot be processed, the door unit (3) itself is removed. It was necessary to process, and the height setting was not easy.
[0005]
The invention of this application has been made in view of the circumstances as described above, and is to improve the prior art and to provide a new doorrest mounting structure capable of easily mounting and setting the height of the doorwheel. It is an issue.
[0006]
[Means for Solving the Problems]
The invention of this application is, as a solution to the above-mentioned problem, firstly, a door-car attachment structure in which a door-car unit including a car and a door-car frame body is attached to an opening provided in a lower end of the door, The opening has an opening shape that is longer than the height of the door unit, and has a plurality of uneven portions on its inner wall surface, and the door unit has the uneven portion on the outer wall surface of its door frame. It has a concavo-convex part corresponding to the part, the concavo-convex part is fitted to each other, the door unit is attached to the opening, and the butt cover body is attached by being sandwiched from the left and right outer sides of the lip part after the door unit is attached Provided is a door carriage mounting structure.
[0007]
In addition, the invention of this application provides, secondly, a door pulley mounting structure characterized in that the lip portion has a substantially real shape .
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The invention of this application has the features as described above, and the embodiment will be described in more detail below with reference to the drawings.
[0009]
FIG. 1 is a perspective view illustrating an embodiment of the invention of this application. For example, as illustrated in FIG. 1, the invention of this application is based on a door (31) and a door frame (32) in an opening (2) provided in the lower end (11) of the door (1). The door (2) has an opening shape that is longer than the height of the door roller unit (3) and has a plurality of steps on the inner wall surface. The concavo-convex portion (21) has a concavo-convex portion (321) corresponding to the concavo-convex portion (21) on the outer wall surface of the door frame (32). The concavo-convex portions (21) and (321) are fitted to each other so that the door unit (3) can be attached to the opening (2). Thus, the door unit (3) can be easily attached. And height setting is realized.
[0010]
Further explaining in this case, in the embodiment of FIG. 1, the opening (2) has a width and a depth that match the outer dimensions of the door frame (32) of the door unit (3). Is somewhat longer than the height dimension of the door frame (32), that is, it is vertically long enough to allow adjustment of the mounting height position of the door wheel unit (3) described later. In addition, on the inner wall surfaces on the left and right sides sandwiching the door roller unit (3) of the opening (2), a plurality of concavo-convex portions (21) extending from the entrance of the opening (2) to the back are provided continuously in a vertical direction. ing.
[0011]
On the other hand, the door unit (3) has a shape corresponding to the uneven portion (21) of the opening (2) on the left and right outer wall surfaces of the door frame (32) such as a case body that pivotally supports the door wheel (31). The concavo-convex part (321) is provided in a plurality of stages and continuously up and down.
[0012]
Then, the door roller unit (3) is inserted into the opening (2) from the front end of the door (1) by fitting the concave and convex portions (21) and (321). FIG. 2 shows a state after this insertion and attachment.
[0013]
Thus, the insertion attachment by fitting of the concave and convex portions (21) and (321) makes it possible to easily realize the firm attachment of the door unit (3), and the concave and convex portions (21) and (321) are open. Since it has a shape that extends to the back of (2), the load applied when the door (1) travels can be firmly received, and loosening and displacement of the door unit (3) can be eliminated, resulting in smooth travel Will always be maintained. Furthermore, as shown in FIGS. 2 (a) and 2 (b), the opening (2) has an opening shape that is vertically longer than the height of the door roller unit (3), and the concavo-convex portion (21) is provided. Since the upper and lower inner wall surfaces of the opening (2) are continuously provided in the vertical direction, the door roller unit (3) can be mounted at an arbitrary height position in the vertical margin space of the opening (2). The height can be easily set. In addition, as illustrated in FIG. 2B, the lower part of the door (1) may need to be cut in some cases, but the conventional process of widening the opening (2) and the door unit (3) itself. No complicated processing such as the above processing is required.
[0014]
In addition to the triangular structure illustrated in FIGS. 1 and 2, the shape of the concave and convex portions (21) and (321) is, for example, a rectangular wave shape illustrated in FIG. The sawtooth wave shape shown in b) can be used, and even if not all the concave and convex portions (21) and (321) are continuous, It may be. The point is that the concave and convex portions (21) and (321) may mesh with each other when the door unit (3) is mounted in the opening (2) while shifting the height position as described above.
[0015]
Now, after attaching the door cart unit (3) to the opening (2), for example, the top cover body (4) illustrated in FIG. 4 is attached to the mouth portion (11) after the door cart unit (3) is attached. It is preferable. In this case, the attachment of the lip cover body (4) is, for example, fitted with the lip portion (11) having a substantially real shape as illustrated in FIG. 5 (a), or as illustrated in FIG. 5 (b). The mouth part (11) can be sandwiched from the left and right outsides, thereby covering the opening (2) and the door unit (3) in the mouth part (11) to improve the appearance and aesthetics. Of course, it is also possible to prevent the opening (2) from spreading due to impacts during travel, aging deformation, and the like.
[0016]
