Further, in the present specification, the “summing direction” means a direction in which adjacent door bodies are summoned, and this summing direction is a direction intersecting with the opening / closing direction of the door body, For example, in the case where the door body is configured to open and close in the left-right direction, the summing direction is the up-down direction .

Since the said form is comprised as demonstrated above, there exists an effect as described below.
According to the first embodiment , in the normal opening / closing operation, the gap between the door bodies is closed by the opposing summing elastic body.
In addition, even when one or both of the summing elastic bodies are deformed by intentionally pressing between the two summing elastic bodies with a finger or a tapered object in the closed state of the door body, the deformation at that time Since it is partially suppressed by the deformation suppressing means, it is possible to prevent a gap that is intentionally looked into by a third party between the opposing summing elastic bodies.

Further, according to the second form , in the closed state of the door body, the space between the two summing elastic bodies from the other wall portion side thinner than the one wall portion is intentionally formed by a finger or a tapered object. Even if the thin wall on the other side is elastically deformed, it is difficult for the wall on the other wall to be elastically deformed. It is possible to prevent a gap that can be seen from being formed.

Furthermore, according to the third aspect , the thick wall portion and the thin wall portion are opposed to each other in the door body width direction on each of the door body front side and the door body back side by the opposing summing elastic bodies. And it arrange | positions along with the door body thickness direction.
Therefore, for example, from the front side of the door body, when the space between the thick wall portion and the thin wall portion facing in the door body width direction is intentionally pressed by a finger or a tapered object, the finger or taper shape Since an object etc. is escaped to the thin wall part side avoiding the thick wall part which is comparatively hard to deform, the thin wall part is elastically deformed.
However, the elastic deformation of the thin wall portion is difficult to reach the thick wall portion on the back side of the door body. Moreover, the same effect is obtained when it is intentionally pressed from the back side of the door by a finger or a tapered object.
Therefore, it is possible to effectively prevent a gap that is intentionally viewed by a third party between the opposing summing elastic bodies.
In addition, when a finger or object is sandwiched between the opposing elastic bodies, it is possible to prevent pressure from being applied to the finger or object by elastic deformation of the thin wall portion. it can.

Further, according to the fourth embodiment , even if the summing elastic body is deliberately pressed by a finger or a tapered object and a pressing force is applied to the summing elastic body, the tip of the deformation suppressing rib does not move. Since it abuts against the edge of the door body, the deformation of the summing elastic body is suppressed, and a gap that is intentionally looked into by a third party between the opposing summing elastic bodies is prevented. Can do.
In addition, in the closed state of the door body, in the unlikely event that a finger or an object is sandwiched between the two summing elastic bodies, one or both of the summing elastic bodies are within the space of the deformation space. By elastically deforming, the pressing force received by the finger or object can be reduced.

Furthermore, according to the fifth embodiment , since the deformation suppressing rib is arranged on the center side in the door body thickness direction in the hollow portion, the door body front side or the door body rear side with respect to the opposing summing elastic bodies When a pressing force such as a finger or a tapered object is applied from the side, the pressing force can be made difficult to transmit to the deformation suppression rib. It is possible to more effectively prevent such a gap from being formed.

Furthermore, according to the sixth aspect , the hard reinforcing portion can prevent the deformation suppressing rib from being intentionally pressed and deformed by a finger or a tapered object.

Further, according to the seventh embodiment , when a pressing force such as a finger or a tapered object is applied to the one side wall portion in each summing elastic body, the hard reinforcing portion opposes the pressing force. Therefore, it is possible to prevent the one side wall portion from being elastically deformed.
Further, when a pressing force such as a finger or a tapered object is applied to the other side wall portion of each summing elastic body, elastic deformation due to the pressing force hardly reaches the one side wall portion. Therefore, it is possible to prevent the one side wall portion from forming a gap that is intentionally looked at by a third party.

Further, according to the eighth aspect , the wall portions that contact the hard reinforcing portion and the wall portions that do not contact the hard reinforcing portion are arranged to face each other in the door body width direction by the opposing summing elastic bodies. And it arrange | positions along with the door width direction.
Therefore, for example, when the space between both wall portions facing in the width direction of the door body from the front side of the door body is intentionally pressed by a finger or a tapered object, the finger or the tapered object is It escapes to the wall part side which is not touching, and tries to elastically deform the wall part which is not in contact with the hard reinforcement part. However, the elastic deformation hardly reaches the wall portion reinforced by the hard reinforcing portion on the back side of the door body. The same effect is obtained when it is intentionally pressed from the back side of the door by a finger or a tapered object.
Therefore, it is possible to effectively prevent a gap that is intentionally viewed by a third party between the opposing summing elastic bodies.
Moreover, if a finger or object is sandwiched between the two elastic bodies, the pressing force applied to the finger or object is reduced by elastic deformation of the wall that is not in contact with the hard reinforcement. can do.

Further, according to the ninth aspect , even if the summing elastic body is deliberately pressed by a finger or a tapered object and a deformation force is applied to the summing elastic body, the deformed summing elastic body Since the inner surface of the abutment comes into contact with the tip of the hard reinforcement part, the deformation of the summing elastic body is suppressed, and a gap that is intentionally looked into by a third party is formed between the opposing summing elastic bodies. Can be prevented.
In addition, in the closed state of the door body, in the unlikely event that a finger or an object is sandwiched between the two summing elastic bodies, one or both of the summing elastic bodies are within the space of the deformation space. By being elastically deformed, it is possible to reduce the finger, object and the like from receiving a pressing force.

Further, according to the tenth embodiment , even if both the opposing elastic bodies are deliberately pressed by a finger or a taper, and one or both of the elastic elastic bodies are elastically deformed, these both automatic Since the mating elastic bodies are engaged in a concave-convex shape over the door summoning direction, it is possible to prevent a gap between these summing elastic bodies from being intentionally looked into by a third party. Can do .

It is.

  The deformation space portion w1 is formed by elastic deformation of the summing elastic body 53 and / or the summing elastic body 54 when a finger or an object is sandwiched between the opposing summing elastic bodies 53 and 54. Therefore, when the pressing force against the finger or the like is reduced and the space between the summing elastic bodies 53 and 54 is intentionally pressed by a finger or a tapered object, the deformation suppressing rib 53e (and / or 54e) ) Is suitably set so that the elastic deformation of the summing elastic body 53 (and / or 54) is suppressed.

Thus, according to the summing structure of the folding door apparatus 2 shown in FIG. 4, when the summing elastic bodies 53 and 54 are deliberately pressed by a finger or a tapered object, the deformation suppressing ribs 53e (and And / or 54e) comes into contact with the fastening bracket 13, so that the elastic deformation of the summing elastic body 53 (and / or 54) is suppressed, and a gap between the two summing elastic bodies 53 and 54 can be seen. Can be prevented from being formed.
Further, when a user or the like sandwiches a finger or an object between the summing elastic body 53 and the summing elastic body 54, the summing elastic body 53 (and / or 54) is used for deformation. By making the elastic deformation within the interval of the space part w1, it is possible to reduce the pressing force on the finger or the object.

According to the example shown in FIG. 4, the wall portions 53a and 54a on one side are formed thicker than the wall portions 53b and 54b on the other side, but conversely, the wall portions 53b and 54b on the other side are You may make it form thicker than the side wall parts 53a and 54a.
Further, according to a preferred example shown in FIG. 4, by forming one wall portion 53a (or 54a) of the summing elastic body 53 (or 54) thicker than the other wall portion 53b (54b), Although the same effect as the summing elastic body 51 (and 52) is obtained, both thicknesses can be made substantially the same.
Further, in the example shown in FIG. 4, the protrusions of the deformation suppressing ribs 53e and 54e are formed in a wide shape such as a substantially T-shaped cross section so that the contact between the protrusion and the fixing bracket 13 is stabilized. Thus, the deformation suppressing effect may be improved.
In the example shown in FIG. 4, the fastening bracket 13 is made of a hard material separate from the summing elastic bodies 53 and 54, but the fastening bracket 13 is integrated with each of the summing elastic bodies 53 and 54. An elastic body may be used.

  5 replaces both summing elastic bodies 51, 52 in the folding door apparatus 1 with summing elastic bodies 55, 56, and also includes a fastening bracket 13 in the folding door apparatus 1. Is replaced with a fastening bracket 14, and a deformation suppressing means is constituted by a hard reinforcing portion 14 a provided on the fastening bracket 14.

In one summing elastic body 55, both wall portions 55a and 55b arranged in the door body thickness direction are formed to have substantially the same thickness t, and a convex portion 55c and a concave portion 55d are formed on the protruding end side.
Similarly, in the other summing elastic body 56, both wall portions 56a and 56b arranged in the thickness direction of the door body are formed with substantially the same thickness t, and a convex portion 56c and a concave portion 56d are formed on the protruding end side. doing.

Further, the fastening bracket 14 is configured to integrally include a hard reinforcing portion 14a with respect to the fastening bracket 13 described above.
The hard reinforcing portion 14a is a portion made of a hard material that is integrally formed when the entire fastening bracket 14 is processed, and the summing elastic body 55 (in the door body thickness direction with the hollow portion s interposed therebetween) Or 56) of the two wall portions 55a and 55b (or 56a and 56b), and contacts the inner surface of the wall portion 55a (or 56a) on one side and the wall portion 55b (or 56b) on the other side. Is provided so as not to contact.
Explaining in more detail about the illustrated example, the hard reinforcing portion 14a protrudes along the inner surface of the wall portion 55a (or 56a) on one side, and abuts against the surface of the concave portion 55d (or 56d) on the side of the hollow portion s. Yes.

Further, the convex portion 55c (or 56c) is continuous with the protruding end side of the wall portion 55a (or 56a) on one side, and is fitted in the concave portion 56d (or 55d) facing each other, as in the above-described summing elastic body 51. Adapted.
According to the illustrated example, the concave portion 55d (or 56d) is formed in a concave shape having a slightly deeper bottom than the above-described summing elastic bodies 51 and 52, and the opposing convex portion 55c (or 56c) is fitted deeper. Match. According to this configuration, it is possible to more effectively prevent a gap from being formed between the summing elastic bodies 55 and 56 when it is intentionally deformed.

Thus, according to the summing structure of the folding door device 3 shown in FIG. 5, for example, both summing elastic bodies 55 and 56 are deliberately pressed by a finger or a tapered object from the door body front side (the lower side in the figure). When this is done, elastic deformation of the wall portion 55b of one summing elastic body 55 is suppressed by the hard reinforcing portion 14a. Therefore, the finger or the tapered object elastically deforms the wall portion 55 a of the other summing elastic body 56, but the elastic deformation does not reach the back wall portion 55 b of the summing elastic body 56. That is, since the back wall 55b is reinforced by the hard reinforcing portion 14a, as described above, even if the front wall 55a is deformed, it is not easily deformed.
Also, for example, if a finger or an object is sandwiched between the summing elastic bodies 55 and 56 from the front side, it is sandwiched by the elastic deformation of the wall portion 55a that is not received by the hard reinforcing portion 14a. It is possible to reduce the pressing force applied to the finger or object.

  In the embodiment shown in FIG. 5, if the wall portion 55b (or 56b) and the hard reinforcing portion 14a are bonded with an adhesive, the deformation suppressing effect by the hard reinforcing portion 14a can be further improved.

Further, the folding door device 5 whose main part is shown in FIG. 6 has a configuration in which one fastening bracket 14 is replaced with a fastening bracket 15 with respect to the folding door device 2 (see FIG. 2) described above.
The fastening bracket 15 is configured to integrally include a hard reinforcing portion 15a so as to face the other fastening bracket 14 with respect to the above-described fastening bracket 13.
The hard reinforcing portion 14a is a portion made of a hard material that is integrally formed when the entire fastening bracket 15 is processed, and is opposed so as to contact along the inner surface of one wall portion 56a of the summing elastic body 56. Projecting toward the summing elastic body 55, and securing a deformation space w2 for elastically deforming the summing elastic body 56 by a predetermined amount between the protruding end and the inner surface of the summing elastic body 56. Yes.

  The deformation space portion w2 is formed on the protruding side of the wall portion 56a of one summing elastic body 56 (in other words, when a finger or an object is sandwiched between the opposing summing elastic bodies 55, 56). In this way, the portion on the summing elastic body 55 side is elastically deformed to reduce the pressing force on the finger and the like, and when it is intentionally elastically deformed, the elastic deformation is suppressed by the hard reinforcing portion 15a. Are set appropriately.

Thus, according to the summing structure of the folding door device 4 shown in FIG. 6, the space between both summing elastic bodies 55 and 56 is deliberately pressed from the front side (the lower side of FIG. 6) by a finger or a tapered object. Even so, on the summing elastic body 55 side, the deformation of the wall portion 55b is suppressed by the hard reinforcing portion 14a. Further, on the side of the summing elastic body 56, even if the deformation on the protruding end side of the wall portion 56a is slightly deformed, the deformation becomes a deformation within the interval of the deformation space portion w2. It is possible to prevent a gap from being looked into between 56.
In addition, for example, even when the summing elastic bodies 55 and 56 are deliberately pressed from the back side (upper side in FIG. 6) by a finger or a tapered object, the deformation of the protruding end side of the wall portion 56a is a deformation space. Since the deformation is within the interval of the portion w2, it is possible to prevent a gap from being looked into between the summing elastic bodies 55 and 56.

  In addition, in the aspect shown in FIG. 6, if the wall part 55b (or 56a) and the hard reinforcement part 14a are adhere | attached with an adhesive agent, the deformation | transformation inhibitory effect by the hard reinforcement part 14a (or 15a) will be improved further. Can do.

Moreover, in the folding door apparatus 5 which shows the principal part in FIG. 7, it is set as the structure which replaced each fastening bracket 14 with the fastening bracket 16 with respect to the folding door apparatus 3 (refer FIG. 5) mentioned above.
The fastening bracket 16 has a hard reinforcing portion 16a integrally protruding from the above-described fastening bracket 13 on the center side in the door body thickness direction in the hollow portion s.
The hard reinforcing portion 16a deforms the summing elastic body 55 (or 56) by a predetermined amount between the protruding end and the inner surface of the summing elastic body 55 (or 56) in which the hard reinforcing portion 16a is contained. The amount of protrusion is set so as to secure the deformation space portion w3.
Furthermore, according to a preferred example shown in FIG. 7, the hard reinforcing portion 16 a is disposed so as to be able to come into contact with the bottom of the concave portion 55 d in the surrounding summing elastic body 55 (or 56).

Thus, according to the summing structure of the folding door device 5 shown in FIG. 7, even if the summing elastic bodies 55 and 56 are deliberately pressed from the front side or the back side by a finger or a taper, etc. By causing the bottom inner side of the recess 55d (and / or 56d) in the mating elastic body 55 (and / or 56) to abut against the corresponding hard reinforcing portion 16a, elastic deformation at that time can be suppressed. It is possible to prevent a gap from being looked into between the summing elastic bodies 55 and 56.
Also, when a finger or an object is sandwiched between the summing elastic bodies 55 and 56, the protruding end portion of the summing elastic body 55 and the protruding end portion of the summing elastic body 56 are deformed. By making the elastic deformation within the space of the space portion w3, it is possible to reduce the pressing force applied to the sandwiched finger or object.

  In the summing structure shown in FIGS. 5 to 7, the wall thickness on one side and the wall thickness on the other side of each summing elastic body are substantially equal. It is also possible to make the wall portion on one side of each summing elastic body thicker than the wall portion on the other side in substantially the same manner as the mating structure.

In addition, in the summing structure shown in FIGS. 1 to 7, productivity is improved by making one elastic body and the other elastic body the same shape, but the other elastic body is attached to one elastic body. Different shapes are possible.
Moreover, although the thick wall part, the deformation suppressing rib, the hard reinforcing part, and the like shown in FIGS. 3 to 7 are preferably provided on both of the adjacent door bodies, the structure provided on only one of the door bodies. It is also possible.

  Further, in the summing structure shown in FIGS. 3 to 7, the hollow portion s may be continuous in the longitudinal direction of the summing elastic body (up and down direction according to FIG. 1) and open at both ends. However, as another example, the end portion in the longitudinal direction of the hollow portion s may be closed, and the hollow portion s may be sealed. According to this other example, when the summing elastic body is elastically deformed by an external force, the gas in the hollow portion s is compressed, so that the elastic effect of the gas further increases the deformation suppressing effect of the summing elastic body. Can be improved.
