Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sliding door pulling device that is reliable in operation.

[Conventional technology and problems]

In some types of sliding doors, in order to ensure airtightness in the room or for soundproofing, when the door is closed, a handle attached to the vertical stile is operated to pull the sliding door in the expected direction, and the sliding door is closed using a packing material. It is configured to press against the sash frame and airtightly seal the doorway.

On the other hand, a pulling device in a side stile of a sliding door, for example, an upper stile, is usually guided so as to be movable in the length direction of the upper stile, and the pulling device moves in the length direction in conjunction with the turning operation of the handle. and an engaging member protruding from the bottom side of the upper frame of the sash at a position interfering with the movement locus of the pulling member, and the handle is operated after the sliding door is advanced to the door closing position. The above-mentioned pulling member is advanced toward the engaging member, and by utilizing their mutual interference, the pulling member is moved in the forward direction relative to the engaging member fixedly installed on the sash side. The upper stile of the sliding door is thereby pressed against the packing material attached to the sash frame.

However, in order to fit the sliding door into the sash frame, a considerable amount of space is required between the sash upper frame and the upper stile of the sliding door, and in order to prevent the upper stile from interfering with the engaging member when the sliding door is lifted. , the amount of downward protrusion of the engaging member is limited. On the other hand, the pulling member attached to the interlocking rod on the upper stile side must protrude high upward in order to engage with the engaging member. On the other hand, the interlocking rod equipped with the pulling member requires a certain amount of play between it and the guide member in order to move smoothly.

Therefore, when the engaging member and the pulling member are engaged, the inclination of the former caused by the play between the interlocking rod and its guide member is greatly amplified at the upper end of the pulling member, and the engaging member is A part of the pulling amount of the shoji upper stile, which is determined by the amount of engagement and interference between the mating member and the pulling member, becomes invalid due to the inclination of the pulling member, making it impossible to secure the proper pulling amount.

Therefore, the sliding door pulling device according to the present invention,
For example, it is constructed as shown in FIGS. 6 and 7. That is, in these figures, the reference numeral 43
indicates a pulling member, and the pulling member 43 in the illustrated embodiment is a cam body equipped with a horizontally projected trapezoidal cam surface 43a having a vertical generatrix. are integrally connected to.

Further, an engaging member 44 is provided on the lower surface of the sash upper frame 48.
is installed protrudingly. The engagement member 44 in the illustrated embodiment is a roller having a substantially vertical axis of rotation. The position of this engaging member 44 in the length direction of the sash upper frame 48 is determined when the sliding door is closed and the handle is
When the HL is rotated, it is set to almost align with the pulling member 43, and its relative position with respect to the pulling member 43 in the direction in which the sliding door is viewed is as shown in FIG. The cam surface 43
It is determined to interfere with the movement trajectory of a by an amount of attraction β.

Furthermore, as shown in FIG. 10, the distance γ between the lower end of the engaging member 44 and the upper surface of the upper interlocking rod 33 is
is set to be greater than the overlap depth δ between the lower end of the lower stile of the sliding door A and the lower frame of the sash.

Note that a plurality of sets (two sets in FIG. 9) of the above-mentioned pulling members 43 and engaging members 44 are normally provided along the length direction of the upper stile 36. This also applies to the other sliding door A1.

By the way, in the sliding door pulling device according to the present invention, a support roller 45, which is a support for preventing falling, is rotatably supported on the pulling member 43. In the illustrated embodiment, as shown in FIG. 7, the support roller 45 is located at the indoor end of a horizontal support shelf 43b protruding toward the indoor side, which is the drawing direction side, at the upper end of the drawing member 43. It is located in This support roller 45 rolls in contact with the inner surface of the indoor vertical wall 3a that forms the groove 3 of the upper stile of the sliding door.
In order to prevent the inner surface of the vertical wall 3a from being worn out due to rolling, a wear-preventing back-up plate 47 is integrally connected to the internal surface of the vertical wall, for example, with screws. As shown in FIG. 6, the width of the back-up plate 47 is set to be longer than the amount of movement α of the upper interlocking rod 33 when the handle HL is rotated.

The support roller 45 is in rolling contact with the backup plate 47.

[Effect]

In the sliding door pulling device according to the embodiment of the present invention configured as described above, when the sliding door is advanced to the door closing position, the pulling member 43 is moved against the engaging member 44 fixed to the sash upper frame. Close, 6th
As shown in the figure, a pulling member 43 and an engaging member 44
The distance between them is the movement amount α of the upper interlocking rod 33.
It will be about the same as.

In this state, sliding door A (see Figures 1 and 2)
When the handles HL of the handle device B are rotated clockwise by 180 degrees, the pulling member 43 integrated with the upper interlocking rod 33 moves by α to the left in FIG. 6 due to the configuration of the handle device described above. do. During the movement process, the engaging member 44 first comes into contact with the slope of the cam surface 43a of the pulling member that is inclined with respect to the direction of movement, and then the pulling member 43 moves further to the left in FIG. Due to the wedge effect caused by the movement, the engaging member 44 relatively rides on the central portion of the cam surface 43a. In this case, since the engaging member 44 is fixed to the sash upper frame 48, the pulling member 43 is pushed toward the indoor side (upward in FIG. 6, rightward in FIG. 7), and thus The upper frame of the sliding door is made of Patsukin material 4
6. At this time, the force with which the engaging member 44 pushes the upper stile 36 of the sliding door through the pulling member 43 is applied to the upper stile 36 not through the upper interlocking rod 33 but through the support roller 45 and the back up plate 47. Therefore, the tilting of the pulling member 43 is completely prevented, and the upper interlocking rod 33 and its guide groove 2
3, this pulling device operates reliably regardless of the play.

At the same time, in the door stop frames 1 and 2 of the sliding door, the engaging portions C and D move toward each other in conjunction with the operation of the handle devices B and B1, and due to their mutual engagement, The doorstop frames 1 and 2 are pulled toward the expected direction and are attracted to each other.

That is, when the two handles HL and HL are rotated with a phase angle difference of zero, the longitudinal groove C and the protruding shaft D approach each other in alignment with each other in the direction in which the sliding door is viewed, and the enlarged end of the protruding shaft 31 (see FIG. 2) engages with the inclined surface 30c (FIG. 2) formed at the lower end of the ridge 30a of the longitudinal groove, thereby causing the door stop frames 1 and 2 to mutually They are attracted in the approaching direction, so that the door stop portion of the sliding door is hermetically sealed via the tight members 6, 6 (see FIG. 1).

When rotating the handle HL of one sliding door A first and then operating the handle of the other sliding door A1,
In other words, when the phase angle difference of the handle is 180°, the sliding door A has already been pulled, so as shown in Figure 5, the vertical groove C and the protruding axis D have a pulling amount in the expected direction of the sliding door. It is deviated by B. In this state, if you operate the handle HL of sliding door A1, the fifth
In the figure, only the protruding axis D rises, and soon the protruding axis D and the inclined end edge 30d and/or the distal enlarged portion 3
1 and the inclined inner surface 30e engage with each other, and due to the wedge action generated between them, the door stop stile 2 of the sliding door A1 is pulled in the forward direction, and at the same time, due to the engagement between the tip enlarged portion 31 and the inclined surface 30c. Attraction of doorstops 1 and 2 is performed. two handles
The same applies when the phase angle difference between HL and HL takes other values.

Incidentally, in the sliding door's connecting frame, the hook-shaped latch swung out from the rear pulling mechanism 49 shown in Fig. 9 engages with the strike plate 51 attached to the mullion, and also Each kick pawl 52a of the provided lower pulling mechanisms 52, 52 pushes the rail 53 provided on the lower frame of the sash shown in FIG. It will be done. Since these attracting mechanisms are not the gist of the present invention, further detailed explanations will be omitted.

As shown in FIG. 10, the door wheel 54 attached to the sliding door is hinged to the lower stile via a hinge 55, and can be tilted as shown in FIG. 11 when the sliding door is pulled in. It's becoming like that.

[Other Examples]

Note that the present invention is not limited to the illustrated embodiment, and can be implemented with various modifications.

For example, in the illustrated embodiment, the drawing member is a cam body having a slope inclined with respect to the direction of movement, and the engaging member is a roller. , on the other hand, a support is installed vertically on a board connected to the upper interlocking rod of the pulling member,
A large diameter roller is rotatably supported on its upper end,
The diameter of this large roller may be set so that it can engage with the engagement member and come into contact with the backup plate (not shown).

Further, in the illustrated embodiment, the support roller is depicted as having a vertical rotation axis, but
Of course, the rotating shaft may be inclined as long as it can rollably abut against the backup plate.

Furthermore, a support roller is provided on the vertical wall of the upper stile on the indoor side, and a flat part that comes into contact with the support roller is formed on the side of the pulling member, and their engagement prevents and guides the pulling member. (not shown).

〔effect〕

As is clear from the above explanation, the present invention provides a support for preventing collapse between the pulling member and the vertical wall of the horizontal stile, so that the pulling member receives the force that it receives when it engages with the engaging member. The reaction force for pulling is transmitted to the side stile via the support for preventing collapse, and there is an effect that the pulling member can be reliably operated regardless of play in the upper interlocking rod supporting the pulling member and its guide groove.
