DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing body whose end face faces and separates from a counterpart member by opening / closing movement, and a finger jam prevention member attached to the opening / closing body. Some can be used for sliding doors, hinged doors, folding doors, etc.

[0002]

[Background Art] Balanced door body, sliding door, hinged door,
The end surface of the openable and closable opening / closing body such as a folding door faces an opposing member such as an outer frame, a pillar, or a wall when the opening / closing body is closed, and separates from the opposing member when the opening / closing body is opened. . In the opening / closing body, when the opening / closing body is closed, a finger or the like is prevented from being caught between its end face and a counterpart member, or the end face is made of an elastic material so that it can be easily pulled out even if it is caught. In some cases, a finger stuffing prevention member is attached.

The conventional finger stuffing prevention member has a size corresponding to the thickness of the opening / closing body. Therefore, one entire face of the opening / closing body is covered by one finger stuffing prevention member.

[0004]

According to this conventional finger jam prevention member, it must be formed in a size corresponding to the thickness dimension of the opening / closing body to which the finger jam prevention member is to be attached. There was a problem that a finger jam prevention member had to be prepared for each opening / closing body having a different thickness dimension.

SUMMARY OF THE INVENTION An object of the present invention is to provide an opening / closing member which enables the use of the same finger stuffing prevention member even when the thickness is different, and a finger stuffing prevention member which can be used for the opening / closing member.

[0006]

The opening / closing body according to the present invention comprises:
An opening / closing body having an end face facing the counterpart member and being separated, and having the end face facing away from the counterpart member by opening / closing and having a finger jamming prevention member attached to the end face facing away from the counterpart member, wherein the finger jamming prevention member has an opening / closing body thickness. In a plurality of directions and arranged on the end face.

According to this opening / closing body, the finger stuffing prevention member does not have a size to cover the entire end face of the opening / closing body, and is divided into a plurality in the thickness direction of the opening / closing body.
The opening / closing members having different thickness dimensions can be commonly used, and the cost for the finger jam prevention member can be reduced.

[0008] In the opening / closing body in which the constituent members of the lock device, the latch member, and the like are protruded and retracted from the end face, a finger jam prevention member is provided at two ends arranged on both ends in the thickness direction of the opening / closing body. In this case, it is possible to obtain an effect that it is not necessary to form a hole for allowing the components of the lock device, the latch member, and the like to protrude and retract in the finger jam prevention member.

As described above, the number of the finger jam prevention members divided in the thickness direction of the opening / closing body may be only two disposed at both ends of the opening / closing body at the end face in the opening / closing body thickness direction, or , Including those arranged between them, or four or more.

[0010] When a plurality of finger stuffing prevention members are arranged on the end face of the opening / closing body in the thickness direction of the opening / closing body, the finger stuffing prevention members may contact or overlap with each other with respect to the opening / closing body having a small thickness. .

The entire end face of the opening / closing body may be covered by a plurality of finger jam prevention members.

The structure for arranging the finger stuffing preventing member on the end face of the opening / closing body is optional. For example, each finger stuffing preventing member may be provided with a fastener such as a screw or a rivet, a double-sided tape, an adhesive or the like. The opening / closing body itself may be provided with a portion for locking or engaging the finger jam prevention member, and the locking / engaging portion may be used. At the end face, a plurality of locking members provided with a plurality of locking portions spaced apart in the thickness direction of the opening and closing body are attached, and a plurality of finger jam prevention members divided in the thickness direction of the opening and closing body are locked with these locking members. It may be carried out by engaging with a part.

[0013] According to the last arrangement structure, the operation of arranging the finger jam prevention member can be easily performed by the locking action of the locking member attached to the end face of the opening / closing body.
This can be performed without forming a special shaped portion such as a locking portion or an engaging portion on the opening / closing body.

The locking portion of the locking member in this arrangement may have any shape as long as it can lock the finger jam prevention member. In one example, the locking portion of the locking member has a length extending from the end face to the end face side opposite to the opening / closing body, and the finger jam prevention member has a length from the front to the length direction of the locking portion. By forming a cut groove and inserting a locking portion into the groove, the finger jam prevention member is locked to the locking member.

According to this arrangement, the finger-jamming prevention member is immovable in the thickness direction of the opening / closing body by the locking portion of the locking member, and the rear end of the finger-jamming preventing member is brought into contact with the opening / closing body. The finger stuffing prevention member is also immovable in the width direction of the opening / closing body, so that the finger stuffing prevention member can be reliably positioned and arranged.

The structure for attaching the locking member to the end face of the opening / closing body is arbitrary.
A fastening tool such as a screw or a rivet, a double-sided tape, an adhesive, welding, or the like may be used. Alternatively, the locking member itself may be provided with a portion that is locked, engaged, or fitted to the opening / closing body. May go.

Further, one or more of the finger jamming prevention member and the locking member may be provided over the entire length of the end face facing and separated from the mating member, and may be provided partially in the length direction of this end face. Alternatively, the lengths of the finger jamming preventing member and the locking member in the length direction of the end surface may be different.

Further, the locking member may be attached to the end face of the opening / closing body first, and then the locking member may be locked with the finger jamming preventing member. The prevention member may be locked, and thereafter, the locking member may be attached to the end surface of the opening / closing body, and the locking member may be capable of performing one or both of these operations.

In the above, the finger jam prevention member may be entirely formed of a solid or hollow elastic material.
An outer member made of an elastic material may be covered on the outside of the inner member made of a hard material.

When the finger stuffing prevention member has an internal member formed of a hard material, the overall strength of the finger stuffing prevention member can be secured, such as before the finger stuffing prevention member is attached to the opening / closing body. , The handleability of the finger jam prevention member can be improved.

The term "covering an external member on the outside of the internal member" as used herein refers to a case where the entire internal member is covered with the external member, and a case where the finger-jamming prevention member is attached to the openable / closable member. Do not cover external parts on the part that contacts
It refers to both the case where the remaining part is covered with the external member.

Further, the present invention can be applied to any opening / closing body, and the opening / closing body may be, for example, any of a door body of a balance door, a sliding door, a hinged door, and a folding door, and is movable along a ceiling rail. Or a shutter curtain that moves while being guided by a guide rail of a shutter device.

The opening / closing body may be one that opens and closes an opening such as an entrance formed inside the outer frame, or one that opens and closes by linearly moving or rotating with respect to a pillar or wall. . Therefore, when the opening / closing body is opened and closed, the counterpart member whose end face faces and separates from each other may be a member forming an outer frame or a member forming a building such as a pillar or a wall.

Further, the opening / closing body according to the present invention constitutes a structure which can be opened and closed like a slat constituting a slat type shutter or a panel constituting a panel shutter including an overhead door. In the case where the opening / closing body is this constituent member, the partner member facing and separating this constituent member is another constituent member arranged adjacent to this constituent member.

When the opening / closing body is a door body of a balance door, that is, the opening / closing body is a distal end portion of a swinging member that swings in a horizontal plane about a base end portion, and a middle portion in the width direction is centered on a vertical axis. In the case where the guided member provided rotatably and provided in the middle part in the width direction is a door body of a balance door guided by a guide member extending in the horizontal direction, both sides in the width direction of the door body On each end face of the door body, a finger jamming prevention member divided into a plurality of pieces in the thickness direction of the door body may be arranged, and only one end face in the width direction of the door body may be arranged in a plurality in the thickness direction of the door body. You may arrange | position the divided finger stuffing prevention member.

However, since the end surfaces on both sides in the width direction of the door body of the balance door are opposed to and separated from the respective mating members by opening and closing movement of the door body, the door surfaces are provided on both end surfaces on both sides in the width direction of the door body. It is preferable to arrange a plurality of finger jam prevention members divided in the thickness direction of the main body.

When the present invention is applied to an opening / closing body in which both end surfaces on both sides in the width direction face each other and are separated from each other as in the door body of the balance door, the opening / closing body is divided in the thickness direction. The plurality of finger jam prevention members may be arranged on only one end surface, but are more preferably arranged on both end surfaces.

When the opening / closing member is a door body of a balance door, the swing member may be an upper and lower arm member.
Alternatively, a panel-shaped member having an area facing the front or back surface of the door body may be used.

The finger stuffing prevention member of the opening / closing body according to the present invention comprises:
An end face facing the counterpart member by opening / closing movement is a finger jamming prevention member attached to the end face of the opening / closing body separated from the counterpart member, and is separately attached to both ends of the opening / closing body in the thickness direction of the end face. It is a feature.

According to this finger jam prevention member, since it is separately attached to both ends in the thickness direction of the opening / closing body, various opening / closing bodies having different thickness dimensions can be commonly used. Further, when used for an opening / closing body in which the components and the latch member of the lock device protrude and retract from the end face, holes for allowing the components and the latch member of the lock device to protrude and retract may be formed in the finger jam prevention member. It becomes unnecessary.

Further, the finger jam prevention member according to the present invention, which is separately disposed at both ends in the thickness direction of the opening / closing body on the end face of the opening / closing body, has an L-shaped projecting corner. May be disposed in the recessed portion, or these ends may be recessed recessed portions, and the finger jam prevention member may have a size corresponding to these recessed portions, so that it is stored and arranged in the recessed portion. You may.

According to the latter, since the volume of the finger stuffing prevention member can be increased, a large elastic action of the finger stuffing prevention member at least partially formed of an elastic material can be secured.
