Description

  The present invention relates to a highly safe sliding door that can confirm the other side of the sliding door when opening a sliding door that is slidably provided in an opening of a room and is free of fingers.

  2. Description of the Related Art Conventionally, a sliding door is provided at a predetermined location on the door tip side as an essential component for opening and closing the sliding door. In order to make the opening width of the opening as large as possible, the opening is usually provided with a door retracting portion (for example, a door pocket or a retaining wall) having a depth sufficient to retract the entire sliding door. For this reason, when the sliding door is pulled into the door pull-in portion, the pull-in port (or the vertical) that is the entrance of the door pull-in portion and the door end of the sliding door coincide with each other.

  At this time, there are few gaps between the entrance (or vertical) and the sliding door, and there are many accidents, especially in children, where the finger on the handle is caught between the entrance (or side) and the pull. there were. In view of this, an invention as shown in Patent Document 1 has been proposed as a means for preventing such finger pinching during sliding door opening and closing.

  The invention described in Patent Literature 1 is a pulling groove that continues from the upper end portion to the lower end portion of the sliding door at a portion closer to the front and rear side surfaces (that is, the door tip and the door bottom) of the sliding door as a measure for preventing finger pinching in the pulling handle. In addition, the shape of the pull groove is made difficult to pinch fingers.

  That is, the central portion in the horizontal direction of the pulling groove was projected to form the pulling groove in a substantially M-shaped cross section. In this way, at the final stage of pulling in the sliding door, the fingers touching the vertical provided at the pull-in opening of the door pull-in part are automatically discharged along the inclination of the pulling groove along with the pulling operation of the sliding door, It is said that hands and fingers will not be caught between

Japanese Patent No. 4801577 (FIG. 9)

  However, as mentioned above, the special shape that forms the pulling groove with a substantially M-shaped cross-section greatly affects the design of the sliding door, impairing the uniformity of the design. There is a risk of being caught between a narrow sliding door and a vertical stand without sliding on the inclined surface of the pulling groove on the street.

In addition, as a lighting or decoration of the sliding door, from the top to the bottom of the door side part, a recessed part fitted with a decorative board material or a daylighting window fitted with a translucent board is provided, and in some cases around it Some have a decorative molding that has a frame-like appearance so as to protrude from the surface of the sliding door .

  In addition, the doors are usually opened and closed using pullers. Especially in the case of a short child, do not use the high puller, but instead use the decorative recess or lighting window in the lower position. Often used. In such a case, there was a case where a finger was pinched between a decorative recess or a lighting window (and a mall provided around the window) and a vertical wall, etc. Not at the moment.

  The present invention has been made in view of the above-described conventional example, and is compatible with a wide range of users while retaining design uniformity, and has no fingertips, and when the opening is closed, either the indoor side or the outdoor side. The challenge is to provide a sliding door that can be seen from both sides.

The sliding door 1 according to claim 1 is:
A circular translucent plate 6c is fitted into the plate-shaped sliding door main body 5 provided in a row in the vertical direction with three concave portions 6 serving as a daylighting window, and the front and back sides of the sliding door main body 5 at the door tip 5d side portion. In the sliding door 1 for infant facilities that is formed by the pulling handles 5a provided on both sides and is slidably attached to the opening 3 having the door retracting portion 4 for storing the sliding door 1,
The installation position of the recess 6 is the door tip 5d side when the sliding door body 5 is divided into the door tip 5d side and the door bottom 5f side.
Among the three recesses 6, at least the lowest recess 6 is provided below the handle 5 a,
Indoor side through a recess 6 corresponding to a user, characterized in that it can be visually recognized state of the opposite side from either chamber outside side.

  According to this, since the recesses 6 are provided in a row in the vertical direction, the adult can visually recognize the opposite side through the uppermost recess 6 and the infant visually recognizes the opposite side through the middle recess 6. it can. That is, when the opening is closed, not only adults but also infants can visually recognize the opposite side from both the indoor side and the outdoor side, and it is safe.

  Since at least the lowermost recess 6 is provided below the handle 5a, and the installation position of the recess 6 is provided on the door tip 5d side of the sliding door body 5, the infant tentatively places the lowermost recess 6 on the handle 5a. Even if it is used in place of, there is no finger pad.

It is a front view which shows the sliding door of this invention. (A) It is a front view of the 1st example of the sliding door used for this invention, (b) It is a front view of the 2nd example. It is a partially-omission cross-sectional view of the opening part equipped with the sliding door of this invention. It is a longitudinal cross-sectional view of FIG.

  The present invention will be described below with reference to FIGS. The sliding door 1 includes a plate-shaped sliding door main body 5, pulls 5 a provided on both front and back surfaces of the sliding door main body 5 at a door-end side portion 5 c, and concave portions 6 provided on the sliding door main body 5 such as a lighting window and a decorative concave portion. Consists of.

  Since the sliding door 1 of the present embodiment is a sliding door, a door wheel 15 (see FIG. 4) is erected on the upper surface end of the sliding door body 5. A guide foot 16 is suspended from the lower end of the sliding door body 5.

The sliding door body 5 is a plate-like body having a height of 1,800 to 2,000 mm × width of 1,000 to 1,100 mm, and a position slightly above the center of the door end side portion 5c (around 1,200 mm from the bottom, that is, The handle 5a is provided on the front and back sides at a position depending on the front and rear door bottom 5f side of 50mm from the door tip 5d at a position of 55% to 60% of the height from the bottom.

  There are various recesses 6 provided on the front and back of the sliding door body 5 depending on the design. In the case of FIG. 1, the sliding door body 5 is a vertically long rectangular recess extending in substantially the entire vertical direction, or a lighting window. A decorative plate 6c (or a translucent plate) is fitted. As shown in FIG. 2, a molding 5h is provided around the recess 6 as necessary (in the case of FIG. 1, there is no molding 5h).

  In the case of FIG. 2 (a), a molding 5h is attached to the periphery of a recess 6 provided in two upper and lower stages formed by a vertically long rectangular recess (or a daylighting window). As shown in FIG. 3, the molding 5h is attached to the inner periphery of the recess 6 in a frame shape, and the decorative plate 6c (or translucent plate) is fitted into the mounting groove 5g formed on the inner periphery. ing.

  In the case of FIG. 2 (b), there are three recesses 6 provided in a row in the vertical direction constituted by circular recesses (or daylighting windows). 5h is provided, and the decorative plate 6c (or translucent plate) is fitted therein.

  The installation position of the concave portion 6 is the door tip side portion 5c, but is provided at a position depending on the door bottom 5f side from the handle 5a, and a part thereof (in the case of FIG. 1, the lower portion of the concave portion 6, FIG. In the case of a), the lower recessed portion 6 is formed below the handle 5a, and in the case of FIG. 2B, at least the lowermost recessed portion 6) is formed. The shape of the recess 6 is merely an example, and is not limited thereto.

  The door-end side portion 5c refers to a portion on the door-end 5d side when the sliding door main body 5 is divided into the door-end 5d side and the door-end 5f side. Further, the door-end-side inner surface 6a of the recess 6 refers to a portion of the inner peripheral surface of the recess 6 formed below the handle 5a that is close to the door-end 5d. Similarly, in the portion where the molding 5h is provided, the portion of the inner peripheral surface of the molding 5h close to the door tip 5d corresponds to the door tip side inner surface 6a.

  And the surface which opposes the retaining wall part 4h in the door butt 5f side edge part of the sliding door main body 5 covers the vertical full length of the sliding door main body 5 (or it covers the vertical full length on the inner surface of the reserved wall part 4h). A mohair 7 for preventing light leakage is attached in an elongated shape. When the mohair 7 is provided in the sliding door main body 5, the inner surface of the vertical 4a on the side of the inlet 4b and the inner surface of the retaining wall portion 4h (or when provided on the retaining wall portion 4h, The length is set to be in sliding contact with the surface of the sliding door main body 5.

  Next, the door retracting portion 4 will be described. The solid line part of FIG. 3 is a retaining wall, and the part containing a virtual line is a door pocket. Hereinafter, the description will focus on the retaining wall, and then a brief description will focus on the different parts of the door pocket.

  The opening 3 is provided at an appropriate position on the wall surface of the room 2, and one parting vertical frame 21 is installed on one inner peripheral surface thereof, and the door faces the opening 3 on the opposite side of the parting vertical frame 21. A lead-in part 4 is provided. A parting horizontal frame 23 is installed from the parting vertical frame 21 of the opening 3 to the back end of the door retracting part 4, and the traveling rail 12 is installed on the lower surface of the parting lateral frame 23 over the entire length in the longitudinal direction. ing. A guide rail 13 having a guide groove 13 a is installed in the floor 8 immediately below the traveling rail 12. The other parting vertical frame 22 is installed at the back end of the door retracting portion 4.

  The retaining wall portion 4h that constitutes the door retracting portion 4 has a narrow wall extending from the other parting vertical frame 22 side of the opening 3 toward the opening 3 in a stepped manner, and a vertical 4a Is attached over its entire length. A door stop rubber 24 is attached to an appropriate position on the inner surface of the parting vertical frame 22. The outer surface of the retaining wall portion 4h constituted by a narrow wall is flush with the wall surface W1 of one wall (upper in FIG. 3) and the other wall (lower in FIG. 3) of the wall W partitioning the indoor space. It is formed in a step shape, and this step portion becomes a door retracting portion 4 into which the sliding door 1 is pulled. Accordingly, the traveling rail 12 and the guide rail 13 are drawn from the full length of the opening 3 to the back end of the door retracting portion 4 along the inside of the retaining wall portion 4h.

  The vertical 4a is wider than the narrow retaining wall portion 4h, and the outer portion of the vertical 4a and the inner portion constituting the lead-in port 4b slightly protrude from the retaining wall portion 4h.

  As shown in FIG. 4, a door wheel 15 of the sliding door 1 is suspended on the traveling rail 12 so as to be able to travel, and a guide foot 16 of the sliding door 1 is slidably fitted into a guide groove 13 a of the floor 8. Yes.

  Next, the relationship between the lateral width of the sliding door 1 and the depth depth L of the door retracting portion 4 will be described. As can be seen from FIG. 3, when the sliding door 1 is pulled into the door retracting portion 4 and the door bottom 5f is brought into contact with the door stop rubber 24, the sliding door 1 is left behind on the sliding door 1 (from the opening end surface 4c of the vertical 4a to the door of the sliding door 1). The portion X up to the tip 5d) occurs, and the gap X between the opening end surface 4c of the vertical 4a and the door-side inner surface 6a of the recess 6 is equal to or greater than the thickness of the finger (specifically, 15 mm or more). Configured as follows. Accordingly, the depth from the opening end surface 4c of the vertical 4a to the door stop rubber 24 is the depth depth L of the door retracting portion 4, which is smaller than the lateral width of the sliding door 1.

  In this case, the gap Y between the surface of the sliding door 1 (the surface of the molding 5h when the molding 5h is provided) and the inner surface of the vertical 4a on the side of the inlet 4b is similar to the above. It is comprised so that it may become more than thickness (specifically, 15 mm or more). Therefore, the distance from the surface of the translucent plate 6c (decorative plate) of the recess 6 to the inner surface on the side of the inlet 4b is 15 mm or more.

  When the sliding door 1 configured as described above is pulled in the direction of opening the opening 3 by placing a finger on the door bottom side inner surface 6b of the recess 6 on the vertical 4a side, the mohair 7 is located on the side of the inlet 4b of the vertical 4a. When passing through the inner surface or the inner surface of the retaining wall portion 4h (or on the surface of the sliding door 1) and further retracting, the door bottom side of the recess 6 before the door bottom 5f of the sliding door 1 abuts against the door stop rubber 24 A finger hung on the inner surface 6b 'hits the stand 4a.

  However, as described above, the decorative plate (translucent plate) 6c of the recess 6 is located at a position (Y = 15 mm or more) that is larger than the thickness of the finger from the inner surface of the vertical 4a on the side of the inlet 4b. Slides on the decorative plate (translucent plate) 6c without being sandwiched between the decorative plate (translucent plate) 6c and the vertical 4a.

  Since the mohair 7 is in contact with the inner surface of the vertical 4a on the side of the inlet 4b and the inner surface of the retaining wall portion 4h (or the surface of the sliding door 1), there is a gap between the vertical 4a and the sliding door 1. Even if there is X, the light does not leak into the next room or hallway. In addition, when the concave portion 6 is a translucent plate, when the sliding door 1 is pulled and the opening 3 is closed, the opposite side can be visually recognized from both the indoor side and the outdoor side. Convenient in

  When the door bottom 5f of the sliding door 1 comes into contact with the door stop rubber 24 and stops, the above-mentioned undrawn Z occurs on the door tip 5d side, and the door tip side inner surface 6a of the recess 6 (in FIG. 3, at the edge of the mall 5h). Since a gap X (X = 15 mm or more) larger than the thickness of the finger is generated between a certain door-end side inner surface 6a) and the opening end surface 4c of the vertical 4a, finger clamping is not generated here either.

  In the case of the door pocket indicated by the phantom line in FIG. 3, the retaining wall portions 4 h and 4 h ′ are provided on both sides of the sliding door 1, and another vertical 4 a ′ is provided on the opening side end face. The relationship between the retaining wall portion 4h and the sliding door 1, the relationship between the retaining wall portion 4h 'and the sliding door 1, the relationship between the vertical 4a and the sliding door 1, and the relationship between the vertical 4a' and the sliding door 1 are the same. In this case, fingers are not jammed on the front and back of the sliding door 1 due to the above-described action.
