Description

  The present invention relates to a pull handle and a sliding door using the pull handle, and more particularly to a technique for ensuring a large finger hooking depth.

  Generally, a sliding door is opened and closed by sliding in the horizontal direction along the surface of the door. In order to facilitate opening and closing of this sliding door, for example, a through hole has conventionally been provided in the door. Thus, a handle is provided in the through hole. This puller is composed of two puller members provided with finger hook recesses on which fingers are hung, and these puller members are fitted and fixed to the through holes of the door from both surfaces of the door ( Patent Document 1).

  However, in this conventional puller configuration, the two puller members are fitted into the through-holes of the door from both surfaces of the door, so even if an attempt is made to increase the depth of each of the finger-hanging recesses, the door panel is at most You can only make it deeper than half the thickness. For this reason, especially when the door panel is thin, it is not possible to secure a sufficient finger hook depth as a handle, making it difficult for elderly people with weak hand strength to open and close the door. was there.

As means for solving this problem, conventionally, it has been proposed that an intermediate plate serving as the bottom of the finger-hanging recess is provided in the handle so as to be movable (see Patent Document 2).
JP 08-246721 A Japanese Patent Laid-Open No. 10-131552

  However, in the pulling handle of the above proposed example, the depth of the finger hanging concave portion can be sufficiently secured by moving the middle plate. For this purpose, each time the sliding door is opened and closed, it is opened from one side and from the other side. In some cases, it is necessary to move the position of the intermediate plate, which is troublesome.

  The present invention has been made in view of such a point, and an object of the present invention is to improve the structure of the two pulling members constituting the pulling handle, so that the recessed portion for hooking the pulling finger without requiring a movable intermediate plate or the like is provided. This is to ensure a sufficient depth.

  In order to achieve the above object, in the present invention, the attachment depths of the two pulling members with respect to the through hole of the door are made different from each other.

Specifically, in the invention of claim 1, the bottomed finger-hanging recesses that are attached to the door mounting holes in the sliding door corresponding to each other from both side surfaces of the door and have the same or substantially the same depth on the entire surface. The first and second handle members have first and second handle members each having a stepped outer peripheral side surface of the handle member from the bottom back surface of the finger hanging recess to the front surface side. By providing a fitting portion to be fitted into the mounting hole of the door , the finger-hanging portion along the direction from the back surface side to the front surface side of the pulling member in the fitting portion of the first pulling member . By making the fitting depth, which is the notch depth from the bottom rear surface of the recess to the stepped portion, smaller than the fitting depth of the second pulling member, the protrusion height of the first pulling member from the door surface is the second. It is characterized by being larger than the handle member.

In this invention, the first and second pull-tab member constituting the tab, while the bottomed finger hanging concave portion of one another identical or substantially the same depth on the entire surface are provided, both pull members back The fitting depth of the fitting portion to the mounting hole in FIG. 3 , that is, the notch depth from the bottom back surface of the finger hanging concave portion to the step portion along the direction from the back surface side to the front surface side of the handle member in each fitting portion. Different from each other, by making the fitting depth of the fitting portion of the first pulling member smaller than the fitting depth of the second pulling member, the protruding height of the first pulling member on the side with the small fitting depth becomes smaller. The protrusion height of the second handle member on the side with the larger fitting depth is larger. Due to the deviation between the depth of the front-side finger-hanging recess and the fitting depth of the back-side fitting portion, the position of the bottom of the finger-hanging recess in both pulling members is shifted from the center position in the thickness direction of the door. The depth of the finger hanging concave portion can be made deeper than that of the handle. This makes it possible to easily open and close the sliding door by securing the depth of the concave portion for hooking the finger without requiring a movable intermediate plate or the like as in the prior art.

  In the invention of claim 2, the sliding door includes a door to which a handle is attached and a retaining wall or a sliding door, and the protruding height of the first pulling member is a gap or a door between the door and the retaining wall. The protrusion height of the second pulling member is smaller than the gap between the door and the retaining wall or the gap between the door and the sliding door. It is a feature.

  In this invention, the first pulling member is used as the mounting hole, from the surface opposite to the door retaining wall or the sliding door, and the second pulling member is used as the mounting hole, the door retaining wall side or the sliding door side. When the sliding door is opened, the second pulling member enters the gap between the door and the retaining wall or the sliding door when the sliding door is opened, and the entire door is the retaining wall or the sliding door. And the opening width of the sliding door can be increased. On the other hand, the first pulling member is used as a mounting hole, from the face of the door's retaining wall side or the sliding door side, and the second pulling member is used as the mounting hole, the face opposite to the door's retaining wall or the sliding door. When the sliding door is opened, the first pulling member comes into contact with the door without entering the gap between the door and the retaining wall or the sliding door, and is located in the finger hanging recess. It is possible to prevent the finger from being caught in the gap between the door and the retaining wall or the sliding door.

  The inventions according to claims 3 to 5 are inventions relating to sliding doors, and the sliding door according to claim 3 is characterized in that the handle of claim 1 is attached. According to the present invention, the same effect as that attained by the 1st aspect can be attained.

  The sliding door of the invention of claim 4 is the sliding door to which the pulling handle of claim 2 is attached, and the first pulling member is attached to the attachment hole from the surface opposite to the retaining wall of the door or the sliding door. On the other hand, the second pulling member is attached to the attachment hole from the side of the retaining wall of the door or the surface of the sliding door.

  In this invention, the 2nd handle member is attached to the surface of the retaining wall side or the sliding door side of the door, and the protrusion height of this 2nd handle member is the clearance gap or door between a door and a retaining wall. When the sliding door is opened, the second pulling member enters the gap between the door and the retaining wall or the sliding door, and the entire door is reserved. It can be opened so as to overlap with the wall or the sliding door, and the sliding door is not left behind, and the opening width can be widened. This is effective when a wheelchair or the like is used.

  The sliding door of the invention of claim 5 is the sliding door to which the pulling handle of claim 2 is attached, and the first pulling member is attached to the attachment hole from the retaining wall side of the door or the sliding door side surface. On the other hand, the second pulling member is attached to the attachment hole from the surface opposite to the retaining wall of the door or the sliding door.

  In this invention, the 1st handle member is attached to the surface of the retaining wall side or the sliding door side of a door, and the protrusion height of this 1st handle member is the clearance gap or door between a door and a retaining wall. Because it is larger than the gap between the sliding door and the sliding door, when the door is opened, the first pulling member hits the retaining wall or the sliding door, causing the sliding door to be left behind, preventing finger jamming, etc. can do.

As described above, according to the first or third aspect of the invention, when the first and second handle members constituting the handle are attached to the door mounting holes in the sliding door from the both sides of the door, respectively, while providing one or bottomed finger hanging concave portion of the whole in mutually the same or substantially the same depth surface of the second pull member, in a direction toward the surface side from the back side of the tab member in the fitting portion of the first pull member The protrusion depth from the door surface of the 1st handle member is made 2nd by making smaller the fitting depth which is the notch depth from the bottom back surface of the recessed part for finger hanging to the level difference part along the 2nd handle member. By making it larger than the pulling member, the position of the bottom of the fingering recess in both pulling members can be shifted from the center position in the thickness direction of the door, and there is no need for a movable middle plate, etc. Ensuring a large depth Te, it is possible to facilitate the opening and closing of the sliding door.

  According to invention of Claim 2, the protrusion height of a 1st handle member is made larger than the space | interval of the clearance gap between the door and a retaining wall in a sliding door, or the clearance gap between a door and a sliding door, and the 2nd handle member The projecting height of the door is smaller than the gap between the door and the retaining wall or the gap between the door and the sliding door, so that the first pulling member is opposite to the door retaining wall or the sliding door When the second pulling member is attached to the side wall and the retaining wall side or the sliding door side surface of the door, the door is opened so that the whole overlaps with the retaining wall or the sliding door. The first pulling member on the side of the retaining wall or the sliding door side of the door and the second pulling member on the opposite side of the door retaining wall or the sliding door. When attached to each surface, finger padding can be prevented.

  According to the invention of claim 4, the first pulling member is attached to the surface of the door opposite to the retaining wall of the door or the sliding door, while the second pulling member is attached to the retaining wall side of the door or the sliding door side. By attaching to the surface, when opening the sliding door, the second pulling member is inserted into the gap between the door and the retaining wall or the sliding door to eliminate the unremaining residue and widen the opening width of the sliding door. It is possible to improve usability when using a wheelchair.

  According to the invention of claim 5, the first handle member is attached to the retaining wall side or the sliding door side surface of the door, while the second pulling member is opposite to the door retaining wall or the sliding door. By attaching to the surface, when the door is opened, the first pulling member is applied to the retaining wall or the sliding door to cause the sliding door to be left behind, thereby preventing finger jamming and the like.

  Hereinafter, the best embodiment of the present invention will be described in detail with reference to the drawings. The following description of the preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its application, or its application.

An opening 4 is provided in the wall 3 that partitions the room R and the outdoor space (not shown), and the opening 4 is opened and closed by the sliding door A. In this embodiment, the sliding door A is a one-sided sliding door, and one half (the right half in FIG. 5) of the opening 4 of the wall 3 is always closed and the other half (the left half in FIG. 5) A retaining wall 10 that defines an entrance / exit B for entering / exiting the chamber R and a door 11 having the same width as the retaining wall 10 that opens / closes the entrance / exit B (the other half of the opening 4) are provided. For example, a duck 7 having a groove (not shown) on the lower surface is formed in the upper part around the opening 4, and a sill (not shown) having a groove or a rail is formed in the lower part on the upper part. The door 11 moves in the horizontal direction while being guided and supported by a groove or rail between the duck 7 and the sill to open and close the entrance B. When the entrance B is opened, the door 11 moves to the right in FIG. Then, the entire space overlaps the clearance wall 10 with a predetermined gap 25 (see FIG. 6). On the other hand, when the doorway B is closed, the door 11 moves to the left in FIG. It is like that. That is, the door 11 of the sliding door A is movable relative to the retaining wall 10.

  A pull handle 14 is provided at a predetermined height position near the edge of the door 11 on the entrance / exit B side to put the hand on the door 11 to open and close it. That is, as shown in FIGS. 1 to 4 in an enlarged manner, a vertically long mounting hole 12 is formed at the handle attachment position of the door 11 so as to penetrate between the indoor and outdoor surfaces of the door 11. The handle 14 is attached to the attachment hole 12. The handle 14 is attached to the attachment hole 12 from the indoor side surface of the door 11, that is, the surface opposite to the retaining wall 10, and from the outdoor surface of the door 11, that is, the surface of the retaining wall 10 side. A second handle member 16. Each of the pair of pulling members 15 and 16 has a vertically long bottomed box shape in which the middle part (the part excluding the peripheral part) on the back surface protrudes on the back side and is long in the vertical direction corresponding to the mounting hole 12 of the door 11. In the surface, vertically long finger-hanging recesses 17 are formed on the surface.

  Further, each of the pulling members 15 and 16 is cut out in a stepped shape from the back surface to the front surface of the pulling member 15 or 16 over the entire outer periphery (or may be partial). Fitting portions 15a and 16a (notches) to be fitted into the mounting holes 12 are formed. By fitting the fitting portions 15a and 16a into the mounting holes 12 of the door 11, the two pulling member 15 is formed. , 16 are attached to the mounting hole 12 so as to correspond to each other so that the bottom back surfaces of the respective finger hanging recesses 17, 17 abut (or face each other with a slight gap) from the front and back side surfaces of the door 11. .

  Screw insertion holes 19 and 19 are formed through the upper end and the lower end of the peripheral edge of the first pulling member 15, respectively. On the other hand, screw holes 20 and 20 are formed on the back surfaces of the upper end and the lower end of the peripheral edge of the second pulling member 16 (surfaces facing the first pulling member 15), respectively. The screw insertion hole 19 of the first handle member 15 is formed in a state in which the fitting portions 15a and 16a of both the handle members 15 and 16 are fitted into the mounting holes 12 of the door 11 as described above. , 19 are inserted through the mounting screws 21, 21, and the mounting screws 21, 21 are screwed into the screw holes 20, 20 of the second pulling member 16, so that both the pulling members 15, 16 are connected to the door 11. Are integrally connected so as to sandwich them. In addition, the attachment and fixing of the pulling members 15 and 16 to the door 11 can be performed by an adhesive, a double-sided adhesive tape, a fitting, or the like in addition to the above-described screwing. However, in consideration of the case where the positions of the first pulling member 15 and the second pulling member 16 are exchanged after the construction, the screwing that can be removed is preferable.

  In order to equalize the degree of finger engagement of the pull handle 14 both on the indoor side and on the outdoor side of the door 11, the depth D 1 of the finger hook recess 17 of the first pull member 15 and the finger hook recess 17 of the second pull member 16. It is preferable that the depth D2 is set to be the same (D1 = D2) or substantially the same (D1≈D2). Further, as shown in FIGS. 1 and 3, if the inner wall of the finger hanging concave portion 17 is recessed with respect to the opening side in each of the pulling members 15, 16, the finger hooking can be improved.

  As the material of the pulling members 15 and 16, for example, metals such as aluminum and stainless steel, synthetic resins such as ABS, polypropylene, polystyrene, and acrylic, wood, etc. can be used. Use.

  Moreover, you may comprise a part or whole of the handle members 15 and 16 with a luminous material. By using the phosphorescent material in this way, the handle 14 emits light even in the dark such as at night, so that the position can be accurately known.

  1-3, as shown in FIGS. 1 to 3, the fitting depths d1 and d2 of the fitting portions 15a and 16a in the pulling members 15 and 16 (the notch depth along the direction from the back surface to the front surface). ) Differs between the first and second pulling members 15 and 16, and the fitting depth d1 of the fitting portion 15a of the first pulling member 15 located on the indoor side is the fitting depth of the second pulling member 16 on the outdoor side. It is smaller than d2 (d1 <d2). And the protrusion height h1 from the indoor side surface of the door 11 of the 1st handle member 15 is larger than the protrusion height h2 from the outdoor side surface of the door 11 of the 2nd handle member 16 (h1> h2). ).

  Further, as shown in FIG. 6, the protruding height h1 of the first pulling member 15 is larger than the interval L of the gap 25 between the door 11 and the retaining wall 10 (h1> L). The protrusion height h <b> 2 of the member 16 is smaller than the distance L of the gap 25 between the door 11 and the retaining wall 10 (h <b> 2 <L).

  Therefore, in this embodiment, in the 1st and 2nd handle members 15 and 16 attached from the both sides of the door 11, the fitting depth d1 of fitting part 15a, 16a fitted to the attachment hole 12 of the door 11 is shown. The fitting depth d1 of the fitting portion 15a of the first handle member 15 attached to the attachment hole 12 from the indoor side surface of the door 11, that is, the surface opposite to the retaining wall 10, is different from the outdoor side of the door 11. The protruding height of the first pulling member 15 on the side having a smaller fitting depth d1 is smaller than the fitting depth d2 of the fitting portion 16a of the second pulling member 16 attached from the surface, that is, the surface of the retaining wall 10 side. Since h1 is larger than the protruding height h2 of the second pulling member 16 on the side with the large fitting depth d2, as shown in FIGS. Finger-fitting recesses 17 in the members 15, 16; 7 at the bottom of the door 11 is attached to the first handle member 15 side, i.e., the indoor side, from the central position C in the thickness direction of the door 11. Depth can be set deeply. Accordingly, the sliding door A can be easily opened and closed by securing a large depth of the finger hanging recesses 17 and 17 of the pull handle 14 without requiring a movable intermediate plate or the like as in the prior art.

  The second handle member 16 is attached to the mounting hole 12 from the surface of the door 11 on the side of the retaining wall 10, and the protruding height h <b> 2 of the second handle member 16 is between the door 11 and the retaining wall 10. Since it is smaller than the gap L of the gap 25, when the sliding door A is opened, the second pulling member 16 enters the gap 25 between the door 11 and the retaining wall 10 as shown in FIG. As a whole, it overlaps with the retaining wall 10 and is opened, so that the sliding door A is not left behind and the entrance / exit B can be widened, which is effective when a wheelchair or the like is used.

(Embodiment 2)
FIG. 7 shows a second embodiment of the present invention (note that the same parts as those in FIGS. 1 to 6 are denoted by the same reference numerals and will not be described in detail), and the first and second handle members 15 and 16 are shown. The mounting position is changed.

  That is, in the first embodiment, as shown in FIG. 6, the first handle member 15 is attached to the mounting hole 12 from the indoor side surface of the door 11, that is, the surface opposite to the retaining wall 10. In the second embodiment, the second handle member 16 is attached to the indoor surface of the door 11, that is, the retaining wall 10, in the mounting hole 12. The first handle member 15 is attached from the opposite surface, and is attached to the attachment hole 12 from the outdoor surface of the door 11, that is, from the surface on the retaining wall 10 side. Other configurations are the same as those of the first embodiment.

  Therefore, in the case of this embodiment, the 1st handle member 15 is attached to the surface at the side of the retaining wall 10 of the door 11, and the protrusion height h1 from the indoor side surface of the door 11 of this 1st handle member 15 is the door 11. Therefore, when the door 11 is opened, the first pulling member 15 hits the retaining wall 10 and the sliding door A is left behind. This can prevent finger filling and the like.

  In the second embodiment, the portion of the first handle member 15 of the handle 14 that contacts the retaining wall 10 may be made of an impact buffering material such as rubber or urethane. Thereby, when the sliding door A is opened, the portion of the shock absorbing material can be brought into contact with the retaining wall 10, and the shock at that time can be absorbed and relaxed.

  In this case, if the surface of the first handle member 15 is covered with a flexible sheet member such as synthetic leather, the apparent difference between the main material mainly constituting the handle 14 and the shock absorbing material. Can be hidden and looks better.

(Other embodiments)
In the above embodiment, the handle 14 has a vertically long rectangular shape. However, the shape of the handle 14 may be a square shape or a circular shape, and it is needless to say that the shape is not particularly limited.

  Moreover, in the said embodiment, although applied to the single sliding door which has the door 11 and the retaining wall 10, this invention is applicable to a double sliding door, a retracting door, a sliding door, etc. When applied to a sliding door, the retaining wall 10 of the above embodiment may be replaced with a sliding door, and the same effect as the above embodiment can be obtained.

  Further, the present invention can be applied not only to a sliding door used for an opening of a building such as a house but also to a sliding storage door.

  INDUSTRIAL APPLICABILITY The present invention is extremely useful in that it can secure a large depth of the concave portion for hooking the finger and facilitate opening and closing of the sliding door, and has high industrial applicability.
