[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an opening / closing body whose end face faces and faces a mating member by opening and closing, and a finger padding prevention member attached to the opening / closing body, for example, a door body of a balance door, a sliding door, a hinged door, a folding door, etc. There is something that can be used.
[0002]
[Background]
The end face of the opening / closing body that can be freely opened and closed, such as the door body of the balance door, sliding door, hinged door, and folding door, faces the mating member such as the outer frame, pillar, wall, etc. when the opening / closing body is closed. When opened, it is separated from this mating member. Among the open / close bodies, when the open / close body is closed, a finger or the like is prevented from being pinched between the end face and the mating member, or the end face is made of an elastic material so that it can be easily pulled out. There are those with a finger padding prevention member attached.
[0003]
The conventional finger padding prevention member has a size corresponding to the thickness dimension of the opening / closing body, and therefore, one end surface of the opening / closing body is entirely covered by one finger padding prevention member.
[0004]
[Problems to be solved by the invention]
According to this conventional finger padding prevention member, it must be formed in a size corresponding to the thickness dimension of the opening / closing body to which the finger padding prevention member is to be attached. There has been a problem that a finger padding prevention member has to be prepared.
[0005]
An object of the present invention is to provide an opening / closing body that can use the same finger filling preventing member even if the thickness dimension is different, and a finger filling preventing member that can be used for the opening / closing body.
[0006]
[Means for Solving the Problems]
The opening / closing body according to the present invention has an end face facing and separating from the mating member, and the finger opening prevention member is attached to the end face facing and separating from the mating member by opening and closing. The stuffing prevention member is divided into a plurality in the opening / closing body thickness direction and arranged on the end face.
[0007]
According to this opening / closing body, the finger padding prevention member does not have a size that covers the entire end face of the opening / closing body, and is divided into a plurality of parts in the thickness direction of the opening / closing body. Can be used in common for different opening / closing bodies, and the cost for the finger padding prevention member can be reduced.
[0008]
Moreover, in the opening / closing body in which the components of the lock device, the latch member, and the like are projected and retracted from the end face, when the number of finger padding prevention members is two arranged at both ends of the opening / closing body thickness direction, This also has the effect that it is not necessary to form a hole in the finger padding prevention member for allowing the constituent members and latch members of these lock devices to appear and disappear.
[0009]
In this way, the number of finger padding prevention members divided in the thickness direction of the opening / closing body may be only two arranged at both ends of the opening / closing body thickness direction of the opening / closing body, or these The number may be three including those arranged between them, or four or more.
[0010]
Further, when a plurality of finger padding prevention members are arranged on the end face of the opening / closing body in the opening / closing body thickness direction, the finger padding prevention members may contact or overlap each other for the opening / closing body having a small thickness dimension.
[0011]
And you may cover the whole one end surface of an opening-and-closing body with a plurality of finger padding prevention members.
[0012]
The structure for disposing the finger padding prevention member on the end face of the opening / closing body is arbitrary. For example, each finger padding prevention member is attached to the opening / closing body with a fastening device such as a screw or a rivet, a double-sided tape, an adhesive or the like. In addition, the opening / closing body itself may be provided with a portion for locking or engaging the finger padding prevention member, and these locking portions or engaging portions may be used. A locking member provided with a plurality of locking portions spaced apart in the opening / closing body thickness direction is attached, and a plurality of finger padding prevention members divided in the opening / closing body thickness direction are engaged with these locking portions. You may carry out by making it stop.
[0013]
Among these, according to the last arrangement structure, the arrangement work of the finger padding prevention member can be easily performed by the locking action of the locking member attached to the end face of the opening / closing body, and the locking body or the engaging part etc. It becomes possible to carry out without forming a special shape portion.
[0014]
Moreover, the latching | locking part of the latching member in this arrangement structure may be arbitrary shapes, if it can latch a finger padding prevention member. One example is that the locking portion of the locking member has a length extending from the end surface to the opposite end surface side of the opening / closing body, and the finger padding prevention member has a length from the front to the length of the locking portion. By forming a cut groove and inserting a locking portion into the groove, the finger padding prevention member is locked to the locking member.
[0015]
According to this arrangement structure, the finger padding prevention member is immovable in the thickness direction of the opening / closing body by the locking portion of the locking member, and the finger padding member is brought into contact with the opening / closing body by bringing the rear end of the finger padding prevention member into contact with the opening / closing body. The prevention member is also immovable in the width direction of the opening / closing body, and the finger padding prevention member can be reliably positioned and arranged.
[0016]
The structure for attaching the locking member to the end face of the opening / closing body is arbitrary, and this attachment may be performed by, for example, a fastener such as a screw or a rivet, a double-sided tape, an adhesive, welding, or the like, or The locking member itself may be provided with a portion that is locked, engaged, or fitted to the opening / closing body.
[0017]
Further, one or more of the finger padding prevention member and the locking member may be provided over the entire length of the end face facing or separating from the counterpart member, or may be provided partially in the length direction of this end face. Furthermore, the lengths of the finger padding preventing member and the locking member in the length direction of the end surface may be different.
[0018]
Alternatively, the locking member may be attached to the end face of the opening / closing body first, and then the operation of locking the finger padding prevention member to the locking member may be performed, or the finger padding prevention member may be first attached to the locking member. After locking, the locking member may be attached to the end face of the opening / closing body, and the locking member may be capable of performing either one or both of these operations.
[0019]
In the above, the finger padding prevention member may be formed entirely of a solid or hollow elastic material, and is formed by covering an outer member made of an elastic material on the outer side of an inner member formed of a hard material. It may be.
[0020]
When the finger padding prevention member has an internal member formed of a hard material, the overall strength of the finger padding prevention member can be secured, and the finger padding before the finger padding prevention member is attached to the opening / closing body, etc. The handleability of the prevention member can be improved.
[0021]
Note that the term “covering the external member on the outside of the internal member” as used herein means that the entire internal member is covered with the external member, and that the opening / closing body and its attached member are contacted when the finger padding prevention member is attached to the open / close body. It means both the case where the portion is not covered with the external member and the other portion is covered with the external member.
[0022]
Further, the present invention described above can be applied to any open / close body, and the open / close body may be, for example, a door body of a balance door, a sliding door, a hinged door, or a folding door, and can be moved along a ceiling rail. A movable partition panel or a shutter curtain that moves while being guided by a guide rail of the shutter device may be used.
[0023]
Further, the opening / closing body may open / close an opening such as an entrance / exit formed inside the outer frame, or may be opened / closed by linear movement or rotation with respect to a column or wall. Therefore, when the opening and closing body is opened and closed, the mating member whose end face faces and separates may be a member that forms an outer frame or a member that forms a building such as a pillar or a wall.
[0024]
Further, the opening / closing body according to the present invention may be a structural member that constitutes a structure that opens and closes like a slat constituting a slat shutter or a panel constituting a panel shutter including an overhead door. When the opening / closing body is this constituent member, the counterpart member that faces and separates from this constituent member is another constituent member that is disposed adjacent to this constituent member.
[0025]
When the open / close body is a door body of a balance door, that is, the open / close body is pivotable about the vertical axis at the front end of the swinging member that swings in the horizontal plane around the base end. And the guided member provided in the middle in the width direction is a door body of a balance door that is guided by a guide member extending in the horizontal direction. The end face may be provided with a finger padding prevention member divided into a plurality of pieces in the door body thickness direction, and is divided into a plurality of pieces in the door body thickness direction only on one end face in the width direction of the door body. A finger padding prevention member may be arranged.
[0026]
However, since the end surfaces on both sides in the width direction of the door body of the balance door face and separate from each mating member due to the opening and closing movement of the door body, the thickness of the door body on each end surface on both sides in the width direction of the door body. It is preferable to arrange the finger padding prevention member divided into a plurality in the direction.
[0027]
When the present invention is applied to an opening / closing body in which the end surfaces on both sides in the width direction face each other and are separated from each other like the door body of this balance door, a plurality of parts divided in the thickness direction of the opening / closing body The individual finger padding prevention members may be disposed only on one end face, but are preferably disposed on both end faces.
[0028]
When the opening / closing body is a door body of a balance door, the swing member may be an upper and lower arm member, or may be a panel-like member having an area facing the front surface or the back surface of the door body.
[0029]
The finger padding prevention member of the opening / closing body according to the present invention is a finger padding prevention member that is attached to the end surface of the opening / closing body that faces and separates from the counterpart member by opening and closing, and the opening / closing body thickness of the end surface It is characterized by being separately attached to the ends on both sides in the direction.
[0030]
According to this finger padding prevention member, since it is separately attached to both ends of the opening / closing body in the thickness direction, it can be used in common for various opening / closing bodies having different thickness dimensions. In addition, when used in an opening / closing body in which the component members and latch members of the lock device appear and disappear from the end surface, a hole for making the component members and latch members of the lock device appear and disappear may be formed in the finger padding prevention member. It becomes unnecessary.
[0031]
Further, the finger padding preventing member according to the present invention, which is separately disposed at both end portions in the opening / closing body thickness direction on the end surface of the opening / closing body, is disposed at the end portion which is a corner portion protruding in an L shape. Alternatively, these end portions may be recessed portions, and the finger padding prevention member may have a size corresponding to these recessed portions, and may be housed and disposed in the recessed portions. .
[0032]
According to the latter, since the volume of the finger padding prevention member can be increased, it is possible to ensure a large elastic action of the finger padding prevention member that is at least partially formed of an elastic material.
[0033]

A spiral spring is housed inside the outer cylinder 52, the lower end of this spring is coupled to the operating shaft 51, and the upper end is coupled to a ring member 61 that is rotatably housed inside the outer cylinder 52. As shown in FIG. 8, the outer cylinder 52 is formed with a window hole 62 through which a part of the ring member 61 is exposed. The window hole 62 is provided at equal intervals over the entire circumference of the ring member 61. A plurality of the holes 63 are facing. The ring member 61 is rotated in one direction by repeatedly inserting and extracting the pins into and out of the plurality of holes 63, whereby the spiral spring is wound, and the spring force is accumulated in the spring 63. By leaving the pin inserted into the pin as it is, the pin is locked to the peripheral portion of the window hole 62, so that the accumulated pressure at that time of the spiral spring is maintained.
[0054]
When the door body 10 that has closed the entrance / exit 1 is opened in such a state, the outer cylinder 52 and the swinging cylinder member 7 are arranged in one direction around the operating shaft 51 (direction in which the spiral spring is wound). When the hand is released from the door body 10, the door body 10 is automatically closed by the accumulated pressure of the spiral spring. The magnitude of the self-closing force of the door body 10 at this time corresponds to the magnitude of the spring force accumulated in the spiral spring.
[0055]
Therefore, the magnitude of the self-closing force of the door body 10 can be determined by the magnitude of the rotation angle when the ring member 61 is rotated by the pin. Further, when the pin is extracted from the hole 63 of the ring member 61, the ring member 61 is in a free state with respect to the outer cylinder 52 and the accumulated pressure of the spiral spring is released. A manual operation type in which the self-closing force of the main body 10 disappears can be used.
[0056]
The outer cylinder 52 is filled with hydraulic oil. Further, inside the outer cylinder 52, an orifice member having an orifice that allows the hydraulic oil to freely pass in one direction and prevent the hydraulic oil from passing in the other direction by a valve member, and a taper pin are inserted. And a hydraulic oil flow restricting member having a through hole through which the hydraulic oil can flow.
[0057]
When the door body 10 that has closed the doorway 1 is opened, the hydraulic oil freely passes through the orifice. Therefore, the opening operation of the door body 10 can be freely performed at the opening speed. On the other hand, when the door body 10 is closed, the orifice is closed by the valve member, and the hydraulic oil flows while being squeezed by the taper pin through the through hole in which the taper pin is inserted. The closing speed is reduced. Since the taper pin moves with respect to the through hole by rotating the disk member 76 on the upper portion of the outer cylinder 52 shown in FIG. 8, the hydraulic oil is passed through the through hole by rotating the disk member 76. The amount of squeezing by the taper pin when circulating can be changed, and thereby the closing speed of the door body 10 can be adjusted.
[0058]
Note that the swinging cylinder member 7 is formed with window holes 80 and 81 for allowing the above-described ring member 61 and disk member 76 to be rotated. At that time, the lid members 82 and 83 are removable.
[0059]
