Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a support guide structure for a sliding door.

[0002]

[Prior art]

 The conventional sliding door support structure used for entrances and exits facing a location exposed to wind and rain is, for example, as shown in FIG.

In FIG. 1, reference numeral 1 denotes a lower frame of a sliding door fitting, which has a relatively high vertical wall surface 2 and a slope 3 having a downward slope toward the outside world a side. 4 is a rail fixed on the slope.

Numeral 5 is a sliding door frame, and door rollers 6 supported by the rails are provided at thick portions of the sliding door frame at appropriate intervals in the longitudinal direction.

Reference numeral 7 denotes an elongated airtight body fixed to the vertical wall surface 2, which seals between the vertical wall surface 2 and the sliding door frame 5 in a weatherproof manner.

Reference numerals 8 and 8 are two-layer glass fixed to a sliding door. And, b is the floor surface of the indoor c, and d is the terrace surface.

In this support and guide structure, when the sliding door is pushed and pulled along the lower frame 1, the door roller 6 is supported and guided by the rail 4, and the sliding door is opened and closed at a fixed position.

When the sliding door is closed, the outside a side is exposed to wind and rain, and when rainwater flows down on the slope 3, this rainwater flows to the lower side by gravity action and is eliminated.

However, when the wind blows toward the sliding door, rainwater on the slope 3 may temporarily flow back to the upper side due to the force of the wind, but this flow is blocked by the vertical wall surface 2 and Rainwater intrusion into the area is prevented. At this time, the elongated airtight body 7 further surely prevents the rainwater from entering.

[0010]

[Problems to be solved by the device]

 In the conventional support guide structure for sliding doors, since the vertical wall surface 2 exists, a large step h is formed between the floor surface b of the indoor c and the terrace surface d, but this step h is aged. This may cause people or persons with disabilities to trip over and fall and be injured, or make it difficult for these people to move by themselves in a wheelchair.

In order to solve this, it is conceivable to form a sloped road e as shown in FIG. 4, but even in this case, there is a problem that the new sloped step is generated due to the existence of the wide sloped surface 3. Is not a solution.

Further, a person often sits down in the existing portion of the lower frame 1 located at the boundary between the indoor c and the outside world a, but the step h is comfortable to sit in in this case. Will be significantly impaired.

An object of the present invention is to provide a support guide structure for a sliding door that can solve such problems.

[0014]

[Means for Solving the Problems]

 In order to achieve the above object, in the present invention, a straight cut groove is provided on the flat upper surface of the lower frame of the sliding door fitting, and an exclusion hole for letting out rainwater from the cut groove is provided on the side surface of the lower frame. A sliding rail is provided on the lower end surface of the sliding door lower frame and is inserted into the cut groove, and the lower rail side surface of the protruding rail is supported by the flat upper surface of the lower frame to support and move the sliding door. Are provided at appropriate intervals in the longitudinal direction of the lower frame.

This invention may be limited as follows: a straight cut groove on a flat upper surface of a lower frame of a sliding door fitting, and a rail arranged in parallel with the cut groove. In addition to the above, the thick wall of the lower frame is provided with an exclusion hole for letting out water that has entered the notch, while the lower end surface of the sliding door lower frame is provided with a protrusion that is inserted into the notch. Doors supported by the rails are provided at appropriate positions in the longitudinal direction of the lower frame at the thick portion of the sliding door lower frame on the side of the.

At this time, the exclusion holes are not provided with a relatively large laterally long passage cross section extending to one side of the lower frame, and a plurality of exclusion holes are provided at appropriate intervals along the bottom of the cut groove.

In order to reliably prevent the intrusion of rainwater, an elongated airtight body for weather-tightly sealing between the vertical wall surface of the cut groove and the vertical wall surface of the ridge is provided on one of these vertical wall surfaces. Attach.

In addition to or in place of this elongated airtight body, an elongated airtight body for weather-tightly sealing between the flat upper surface of the lower frame and the lower end surface of the sliding door lower frame is provided. It can be attached to the lower end of the sliding door frame.

[0019]

[Embodiment of the invention]

 FIG. 1 is a perspective view showing a support guide structure for a sliding door according to the present invention, and FIG. 2 is a partial vertical sectional view of the support guide structure.

As shown in the figure, the lower frame 1 has a flat upper surface 1a, and specifically, is made by processing wood having a square cross section.

Explaining each part thereof, 9 is a straight cut groove provided on the upper surface 1a of the lower frame 1, and has a deeper cross section than a groove of a conventional sliding door. A rail 4 is provided on the upper surface 1a near the cut groove 9 in parallel with the upper surface 1a. The rail 4 is made of stainless steel or the like, and the cross-sectional shape of the upper surface 4a is an inverted triangle so that the center of the width is at the lowest position.

Reference numeral 10 is an exclusion hole provided in the thick portion of the lower frame 1, and specifically has a relatively large laterally long passage cross section toward one side f 1 of the lower frame 1 and a cut groove 9 A plurality are provided at appropriate intervals along the bottom.

Reference numeral 11 denotes an elongated airtight body fixed to the vertical wall surface 9 a of the cut groove 9, and is for sealing the space between the vertical wall surface 9 a and a vertical wall surface 13 a of the protrusion 13 described later in a weatherproof manner. is there. Here, the main body of the elongated airtight body 11 is made of a rubber-like uniform cross-section which is easily elastically deformed and has excellent sealing properties. The elongated airtight body 11 is not limited to this, and may be mohair or the like.

On the other hand, 12 is a sliding door having the following structure. That is, on the lower end surface of the lower frame 5, there is provided a protrusion 13 which is inserted into the cut groove 9.

Doors 6 supported by the rails 4 are provided at appropriate intervals in the direction of the rails 4 at portions of the lower frame 5 near the sides of the ridges 13 at the thickened portions thereof.

Each door roller 6 is formed of a hard material such as stainless steel, and its peripheral surface is formed in a middle-height triangular shape so as to correspond to the shape of the upper surface 4 a of the guide rail 4.

Reference numeral 14 denotes an elongated airtight body fixed to the lower end surface of the lower frame 5, and serves to seal the flat upper surface 1 a of the lower frame 1 and the lower end surface of the lower frame 5 in a weatherproof manner. At this time, the elongated airtight body 14 has a tongue-like uniform cross section.

Next, an example of use of the sliding door supporting and guiding structure according to the present invention having the above-described structure and its operation will be described.

When installing between the indoor c and the terrace surface d, it is preferable that the upper surface 1a of the lower frame 1 has the same height as the floor surface b and the terrace surface d of the indoor c. 10 communicates with the outside world a through the lower side of the terrace surface d.

In this way, there is no step between the upper surface 1a of the lower frame 1, the floor surface b of the indoor c and the terrace surface d, and the lower frame 1 does not hinder the movement of residents or the like. Also, the comfort of sitting at the lower frame 1 is not impaired.

When the upper surface 1a of the lower frame 1 and the terrace surface d cannot be made at the same height, the terrace surface d1 may be lower than the upper surface of the lower frame 1 as shown by the alternate long and short dash line in FIG. . In this case, a sloped road e for eliminating the step formed between the terrace surface d1 and the upper surface 1a of the lower frame 1 is formed, and the exclusion hole 10 communicates with the outside world a through a path that does not interfere. . Thereby, even if the terrace surface d1 and the upper surface 1a of the lower frame 1 are not at the same height, they can be used with the same convenience as when they are the same.

Further, it can be installed at an entrance / exit of a dirt floor such as an entrance door, or as a partition for partitioning a bathroom and a dressing room. Also in this case, the sloped road e is formed if necessary.

Under the installed state of the sliding door of the present invention, since the weight of the sliding door 12 is supported by the door roller 6, and the door roller 6 is supported and guided by the rail 4, the sliding door is opened and closed lightly on the rail 4. It will move.

Further, when exposed to wind and rain under the condition that the sliding door is closed, rainwater tries to enter the cut groove 9, but the elongated airtight body 14 suppresses this intrusion.

However, when the wind and rain become strong, rainwater may enter the cut grooves 9. At this time, the invading rainwater immediately flows out to the outside world a through the exclusion hole 10 and does not stay in the cut groove 9. The elongated airtight body 11 suppresses wind and rain from entering the indoor c through the cut groove 9.

The support guide structure described above can be variously modified, and for example, the following structure can be adopted.

That is, the rail 4 is omitted, and the door roller 6 has a flat peripheral surface and is directly supported by the flat upper surface 1 a of the lower frame 1. At this time, the sliding door 12 is guided by the engagement of the protrusion 13 and the cut groove 9.

Further, as shown in FIG. 3, the door roller 6 may be located on the indoor c side of the cut groove 9. In this way, the door roller 6 is less likely to be exposed to wind and rain, maintenance is less necessary, and its function is maintained for a long period of time.

[0039]

[Effect of the invention]

 According to the present invention configured as described above, a high and wide stepped portion which has been inevitably present in the past is eliminated, and it is particularly easy for elderly people and persons with disabilities to walk or move over the lower frame 1 by a wheelchair. This makes it possible to sit comfortably even on the lower frame 1.

According to the second aspect, the presence of the rail allows the sliding door to be opened and closed smoothly even if the sliding door is heavy, and the function as the sliding door is not impaired.

According to the third aspect, rainwater or dust that has entered the cut groove becomes easy to flow out to the outside, and according to the fourth or fifth aspect, wind and rain are indoors. It is difficult to penetrate.
