Description

  The present invention relates to an anti-clogging tool mounted on a connecting portion of door plates adjacent to a folding door, and a folding door including the same.

The folding door is used as, for example, a storage space such as a closet, a storage cabinet such as a cabinet, an opening / closing door of a room, or a sliding wall (opening / closing wall) for partitioning a room. A member in which a hinge pin of a member is used as a connection fulcrum (folding fulcrum) and is connected so as to be foldable around the connection fulcrum is known.
In the folded door as described above, a plurality of door plates are arranged side by side in a straight line. Further, when opening the folding door, a handle or the like is slid along the guide rail or the like to make a transition (opening) to the open state, and adjacent to the direction perpendicular to the guide rail. It is folded so that the connecting part of the door plate protrudes, and it becomes an open state.
When closing the folding door that is in the open state, a handle or the like is slid along the guide rail to move to the closed state (closed movement), but it is formed between the connected door plates. In a state where the connecting angle (opening angle) is to some extent (for example, about 80 ° to 100 ° or more), the front side portion of the folding door in the vicinity of the connecting portion protruding as described above is arranged on the guide rail side (rear side). The folding door can be closed and closed also by pushing toward the side.

By the way, as described above, each door plate is connected to the folding door by a connecting member such as a hinge. However, a slight gap is formed between the end portions of adjacent door plates on the connecting portion side. The The gap is relatively small, for example, about 0.7 mm to 2.0 mm when the folding door is completely closed, although it depends on the shape and arrangement of the connecting member. However, when shifting from the open state to the closed state, particularly in a state where it can be closed even by pushing a portion near the connecting portion as described above, or in a fully opened state, for example, a maximum of 5 In some cases, a gap of about 0.0 mm or more was formed.
Although this gap is not a gap where adult fingers can be pinched, for infants and the like, there is a risk that fingers may be pinched in the gap. Thus, the gap is reduced to prevent the fingers from being caught (fingered) in the gap.

As another structure for preventing the finger padding in the gap as described above, for example, chamfering the end surface of the connecting portion side of the door plate, or so that finger padding does not occur between the end surfaces of the parts not connected by a hinge or the like. A large gap or a soft member interposed between the end faces has been proposed (for example, Patent Document 1 below).
Moreover, in the following patent document 2, in the folding door which consists of several doors (doorboard) connected so that folding is possible by connection members, such as a hinge, folding of the folding door of any one of the connected doors is carried out. In some cases, a folding door connecting portion structure has been proposed in which a band-like member is fixed to the connecting side end of the surface facing the other door.
The belt-like member is fixed along the vertical direction on the back side of the end of one of the two connected doors and on a portion where no hinge is arranged. Moreover, this strip | belt-shaped member makes a protrusion semicircular, and makes the radius the same diameter as the operating radius of a hinge.
According to this, when opening and closing the door, the edge of the door always comes into contact with the outer periphery of the protruding portion, and the gap in the connecting portion of the door is blocked by the protruding portion of the band-shaped member, It is described that there is no gap when the folding door is opened and closed, and finger padding can be prevented.

Since the locking claw portions 33 and 33 are formed at the front end portion 32 branched into two branches, they can be easily engaged with each other with elastic deformation.
As shown in FIG. 2, the finger plug preventing tool 1 can be easily attached to the folding door 10 by locking the finger block preventing cover body 20 to the support portion 30 as described above.
As described above, an adhesive or the like is applied when engaging the locking claws 33 and 33 of the front end portion 32 of the connection support piece 31 with the locking recesses 23 and 23 of the finger clogging prevention cover body 20. Then, it may be bonded and fixed.
According to the said structure, the said finger clogging prevention tool 1 can be assembled | attached also to the folding door 10 after construction (existing).
Moreover, the latching claw parts 33 and 33 formed in the front end part 32 of the connection support piece 31 as described above are configured to protrude forward from the connection fulcrum 19a of the folding door 10 in the open state. However, as described above, the finger-clogging prevention cover body 20 has a shape that is engaged so as to surround the front end portion 32, so that the assembling property can be improved and these engagements can be achieved. A site | part is not visible and aesthetics can be improved.

Next, a finger-clogging prevention structure in the folding door 10 to which the finger-clog prevention tool 1 having the above-described configuration is attached will be described with reference to FIGS.
As shown in the enlarged view in the alternate long and short dash line in FIG. 2, the folding door 10 is slid by sliding the folding door 10 from the fully opened state until the opening angle θ is about 30 °. As shown in FIG. 5 (a), the connection support piece 31 moves toward the near side with respect to the connection fulcrum 19a with the unfolding operation of the pair of link members 35, 35. . That is, the pair of link-like members 35 and 35 and the door plates 11 and 11 constitute a pantograph mechanism that expands and contracts, so that the pair of link members 11 and 11 increases as the opening angle θ of the door plates 11 and 11 increases. The link-like members 35, 35 are unfolded, and the support piece side pivots 37, 37 move toward the connection fulcrum 19a. Along with this operation, the connection support piece 31 connected to the support piece side pivots 37, 37 moves so as to be pushed forward with respect to the connection fulcrum 19a, and is connected to the front end portion 32 thereof. The body 20 moves forward in the fan-shaped space fs formed between the end faces 13, 13, that is, moves away from the connection fulcrum 19a.

When the folding door 10 is closed until the opening angle θ is about 60 ° as shown in FIG. 5B from the above state, the pair of link-like members 35 and 35 are further improved as described above. The finger clogging prevention cover body 20 moves toward the front side with the unfolding operation. In this state, the end surfaces 13 and 13 on the connecting part cp side of the door plates 11 and 11 and the tapered surface portions 22 and 22 of the finger plug prevention cover body 20 face each other with a predetermined clearance therebetween.
When the folding door 10 is closed until the opening angle θ is about 90 ° as shown in FIG. 6A from the above state, the pair of link-like members 35, 35 are The finger clogging prevention cover body 20 moves toward the front side with further deployment operation. In this state, the first chamfered portions 13a of the end surfaces 13 and 13 and the tapered surface portions 22 and 22 of the finger clogging prevention cover body 20 face each other with a clearance narrower than the clearance. doing.
When the folding door 10 is closed until the opening angle θ is about 120 ° as shown in FIG. 6B from the above state, the finger plug prevention cover body 20 is directed toward the front side as described above. In this state, the second chamfered portions 13a of the end surfaces 13 and 13 and the tapered surface portions 22 and 22 of the finger plug prevention cover body 20 are further narrower than the clearance. They are facing each other with a gap between them.

When the folding door 10 is closed until the opening angle θ is about 150 ° from the above state as shown in FIG. The third chamfered portions 13a of the end surfaces 13 and 13 and the tapered surface portions 22 and 22 of the finger plug prevention cover body 20 are separated by a clearance that is further narrower than the clearance. Are facing each other.
In the state where the folding door 10 is further closed from the above state and is closed as shown in FIG. 7 (b), the finger plug prevention cover body 20 is between the chamfered portions 13a, 13a of the end surfaces 13, 13. The third chamfered portions 13a of the end surfaces 13 and 13 and the tapered surface portions 22 and 22 of the finger clogging prevention cover body 20 are separated by a clearance that is further narrower than the clearance. Close to each other.

As the folding door 10 is closed, the fan-shaped space fs formed between the end faces 13 and 13 on the connecting portion cp side of the door plates 11 and 11 gradually decreases. Accordingly, the anti-clogging cover body 20 is also moved forward by the support portion 30, so that the end faces 13 and 13 and the finger clogging prevention cover body 20 do not come into contact with each other and have a predetermined clearance as described above. In the state where is held, the closing is performed.
The predetermined clearance is such that the end faces 13 and 13 do not come into contact with the finger clogging prevention cover body 20, and at least when fingers are inserted from a state where pressing and closing are possible, fingers and the like are inserted. It may be less than the extent that it is not done. For example, the clearance at the time of closing from a state where pressing and closing is possible may be about 0.5 mm to 2.0 mm.
In this embodiment, as described above, each member of the fingernail preventer 1 is configured so that the predetermined clearance is gradually reduced when the folding door 10 is closed from the fully opened state as described above. And each end surface 13 and 13 of each said doorplate 11 and 11 is formed.

On the other hand, as shown in FIG. 7B, when the folding door 10 in the closed state is opened, the handle 18 (see FIG. 2) is placed on the near side and the fixed side (vertical frame 4 (see FIG. 2)). It is opened by sliding toward the door plate 11 side.
When the folding door 10 is opened, the pair of link-like members 35 and 35 are folded together with the opening operation, contrary to the above-described closing operation.
That is, with the folding operation centering on the connecting fulcrum 19a of each door plate 11, 11, the base side pivots 36, 36 are pivotally attached to the rear surfaces 14a, 14a near the respective end portions of the door plates 11, 11. The pair of link members 35, 35 are folded. When the pair of link-like members 35, 35 are folded, the connection support piece 31 connected to the support piece side pivots 37, 37 moves so as to be pulled backward with respect to the connection fulcrum 19a. Thereby, the finger clogging prevention cover body 20 connected to the front end portion 32 of the connection support piece 31 moves rearward in the fan-shaped space fs formed between the end surfaces 13 and 13, that is, to the connection fulcrum 19a. Moves close to each other.

As described above, according to the folding door 10 to which the antifouling device 1 according to the present embodiment is attached, when the folding door 10 shifts from the open state to the closed state, each end surface of the door plates 11, 11 on the connecting part cp side. Even when a finger is present in the fan-shaped space fs reduced between 13 and 13, the finger clogging prevention cover body 20 faces the space fs forward with respect to the connection fulcrum 19a as described above. Since it moves, fingers are prevented from being stuffed so that fingers are ejected from the space fs.
In addition, the proximity and separation movement of the finger-clogging prevention cover body 20 that is performed in accordance with the opening and closing operations of the folding door 10 is performed while maintaining a predetermined clearance between the end surfaces 13 and 13. As the folding door 10 is opened and closed, the finger-clogging prevention cover body 20 does not slide against the end surfaces 13 and 13, and the end surfaces 13 and 13 and the finger-clogging prevention cover body 20 are not moved. Are not scratched or worn by each other. Thereby, the aesthetics of the said finger clogging prevention cover body 20 and each said end surface 13 and 13 are maintained.

Furthermore, the support part 30 of the finger-clogging prevention device 1 may be provided at an appropriate position in the vertical direction of the finger-clogging prevention cover body 20 so that the finger-clogging prevention cover body 20 can be movably supported. For the folding doors 10 having different lengths (heights), the finger blockage prevention tool 1 can be easily mounted by appropriately adjusting the vertical length of the finger block prevention cover body 20.
Furthermore, in the present embodiment, as described above, in the state in which the folding door is closed, substantially the whole of the finger plug prevention cover body 20 is accommodated between the chamfered portions 13a, 13a of the door plates 11, 11. Since it is set as the structure, the finger clogging prevention cover body 20 arranged in front of the connecting portion cp does not protrude from the front side surface of each door plate 11, 11, and the folding door 10 having excellent aesthetics is obtained.

Further, as described above, the taper surface portions 22 and 22 of the finger clogging prevention cover body 20 and the end surfaces 13a and 13a are closed at least from a state in which the folding door 10 can be pressed and closed. At this time, since the tapered surface portions 22 and 22 are formed so as to move close to each other along the end surfaces 13 and 13, it is possible to effectively prevent the fingers from being caught in the space fs.
That is, for example, if the shape of the back surface side of the finger block prevention cover body is a convex curved surface shape, or the shape of the finger block prevention cover body is a flat plate shape, the portion that faces each end face is close to It becomes relatively small, and it becomes easy for a finger or the like to enter at the part, or when the finger-clogging prevention cover body is pressed with a finger or the like, for example, the left-right direction is easily displaced, and the displacement is generated. In some cases, it may be easier for a finger or the like to enter from a location.
On the other hand, in the present embodiment configured as described above, even when the finger clogging prevention cover body 20 is pushed by a finger or the like and is displaced in either of the left and right directions, The tapered surface portions 22 and 22 face each other when the closing operation is performed at least from a state in which the folding door can be pressed and closed. Therefore, the taper surface portions 22 and 22 on the left and right side portions of the rear surface of the finger block preventing cover body 20 abut on the end surface 13 of the door plate 11 on the side different from the pushing direction, and the finger block preventing cover body 20 moves (displaces). ) Is restricted, it is possible to reduce the expansion of the gap between the finger clogging prevention cover body 20 and the end face 13 on the pushing direction side.
Moreover, a big space | gap is not formed between the finger clogging prevention cover body 20 and each end surface 13 and 13 by the above structures, The aesthetics of the folding door 10 can be improved.

In this embodiment, chamfered portions 13a and 13a are formed at the end portions 12 and 12 on the connecting portion cp side of the door plates 11 and 11 of the folding door 10, and the clogging prevention is performed between the chamfered portions 13a and 13a. Although the cover body 20 has illustrated the aspect made into the shape in which the substantially whole is accommodated in the closed state of the said folding door 10, it is not restricted to such an aspect.
For example, the finger clogging prevention cover body 20 may not be accommodated between the chamfered portions 13a and 13a in the closed state, or the folding door that does not have the chamfered portions 13a and 13a as described above may be used. On the other hand, it is also possible to apply the finger clogging prevention tool 1 according to the present embodiment. In this case, the shape of the finger clogging prevention cover body 20, the length of the connection support piece 31 (the length before and after being inserted through the gap g), the length of the link members 35 and 35, and the mounting angle with the rear surface 14 of the door plate 11 Etc. may be set as appropriate. That is, the fan-shaped space that expands and contracts between the end surfaces of the doors on the connecting part side as the folding door opens and closes is connected so that the finger-clogging prevention cover body does not contact each end surface. What is necessary is just to comprise the support part which makes the finger-clogging prevention cover body and this finger-clogging prevention cover body move and move away from the connection fulcrum so as to move toward and away from the fulcrum.
Further, the shape of the pair of link members 35, 35 of the support portion 30 is not limited to the shape as shown in the figure consisting of two arm portions, but a pair of plate-like bodies such as hinges can be used. It may be an operating piece.

As shown in the enlarged view in the alternate long and short dash line in FIG. 9, the folding door 10B is slid by sliding the folding door 10B from the fully opened state of the folding door 10B until the opening angle θ is about 30 °. 13A, as shown in FIG. 13A, the pair of restricting projections 47, 47 provided on the fixing plates 46, 46 move so as to separate from each other along the circumference. At the same time, they move forward with respect to the connecting fulcrum 19a. At this time, the pair of restricting protrusions 47 and 47 are respectively located at the center side ends of the center side hole portions 45a and 45a (see FIG. 10) of the pair of guide holes 45 and 45 when the folding door 10B is fully opened. However, when the folding door 10B is closed, it moves forward along the pair of guide holes 45, 45 so that the connection operation plate 41 faces forward. Moving. Further, at this time, the pair of guide holes 45, 45 are provided so that the center side holes 45a, 45a (see FIG. 10) are inclined so as to follow the opening directions of the pair of restricting projections 47, 47, respectively. Therefore, the amount of forward displacement of the coupling operation plate 41 accompanying the movement of the pair of restricting projections 47, 47 is relatively small.
Further, when the connection operation plate 41 moves forward, the finger clogging prevention cover body 20 connected to the front end portion 42 moves forward in the fan-shaped space fs formed between the end faces 13 and 13. It moves toward, that is, moves away from the connection fulcrum 19a.

  From the above state, as shown in FIG. 13B, when the folding door 10B is closed until the opening angle θ is about 60 °, the pair of restricting projections 47, 47 are similar to the above. In addition to moving further away, each moves forward. At this time, the pair of restricting protrusions 47, 47 are arranged so as to extend along the side portion side holes 45b, 45b (see FIG. 10) formed along the left-right direction of the pair of guide holes 45, 45. As described above, the connection operation plate 41 moves forward, and the finger clogging prevention cover body 20 moves toward the front side. In this state, as in the first embodiment, the end surfaces 13 and 13 of the door plates 11 and 11 on the connecting part cp side and the tapered surface portions 22 and 22 of the finger plug prevention cover body 20 have a predetermined clearance. They are facing each other at a distance.

  In addition, as shown in FIG. 14A, when the folding door 10B is closed until the opening angle θ is about 90 ° from the above state, the pair of restricting protrusions 47, 47 as described above. However, the pair of guide holes 45, 45 are moved along the side holes 45b, 45b, and the pair of guide holes 45, 45 are regulated so that, similarly to the above, the connection operation plate 41 is moved forward. The finger clogging prevention cover body 20 moves toward the front side. In this state, the first chamfered portions 13a of the end surfaces 13 and 13 and the tapered surface portions 22 and 22 of the finger clogging prevention cover body 20 face each other with a clearance narrower than the clearance. doing.

From the above state, as shown in FIG. 14B, the state until the opening angle θ is about 120 °, and from that state, as shown in FIG. 15A, the opening angle θ is about 150 °. In the state up to this point, as shown in the respective drawings, the pair of restricting projections 47, 47 are provided at the laterally outer end portions of the side hole portions 45b, 45b of the pair of guide holes 45, 45, respectively. When the pair of restricting protrusions 47, 47 are moved along the circumference, the connection actuating plate 41 is moved forward, and the finger plug prevention cover body 20 is moved toward the front side. To do. In this state, the pair of regulating projections 47, 47 along the side holes 45b, 45b of the pair of guide holes 45, 45 have a relatively small amount of displacement in the left-right direction, and the pair of regulating projections. The amount of forward displacement of the connection operation plate 41 due to the movement of 47, 47 along the circumference is relatively large.
In each of the above states, as shown in FIG. 14B, when the opening angle θ is about 120 °, the second chamfered portions 13a of the end surfaces 13 and 13 and the finger clogging prevention cover body 20 The tapered surface portions 22 and 22 face each other with a clearance further narrower than the clearance.
