Description

  The present invention relates to a fore edge cover that covers a fore edge of a cover member and an outer surface area of the elongate member that are attached to a groove-like portion of the elongate member.

  In a fitting such as a sliding window in which a shoji is slidably disposed with respect to the opening frame, there is one in which a cover member is provided on a prospective surface located on the indoor side in the upper frame (long member). A cover member is arrange | positioned at the groove-like part provided in the prospective surface of the upper frame along the longitudinal direction, and has a cover part and an engagement piece part. A cover part is a part which covers the prospective surface of an upper frame, and is comprised by flat form. The engagement piece portions are a pair of fin portions provided on the back surface of the cover portion, and are formed to dimensions that can be attached and engaged with the groove portions of the upper frame.

  If the cover member is attached to the groove-shaped portion of the upper frame via the engagement piece portion, the prospective surface of the upper frame can be covered by the cover portion. Therefore, the designability of the joinery to be applied can be improved. Moreover, even when condensed water adheres to the upper frame, it is possible to prevent a situation in which the water drops from the upper frame (see, for example, Patent Document 1).

  It is preferable that the cover member can be disposed over the entire length along the longitudinal direction of the upper frame. However, there are cases where it is difficult to arrange the cover member over the entire length, for example, parts are mounted on the prospective surface of the upper frame. When the cover member cannot be disposed over the entire length of the upper frame, the fore edge of the cover member appears on the prospective surface of the upper frame, which is not necessarily preferable in view of design.

  In order to cover the edge of the cover member, there is a method of attaching the edge cover to the groove-like portion of the upper frame. As the cover cover, like the cover member, a cover having a flat plate-like portion and an insertion engaging portion protruding from the back surface of the plate-like portion is applied, and the small cover is inserted into the groove-like portion of the upper frame. The joint portion may be inserted, and the plate-like portion may cover the fore edge of the cover member and the prospective surface of the upper frame. However, if the fore edge cover is simply inserted into the grooved portion of the upper frame, the movement along the longitudinal direction cannot be restricted, so that the fore edge cover and the cover member move relative to the upper frame. It is difficult to expect the effect.

  As a technique for restricting the movement of the member inserted into the long member, an elastic tongue piece is provided on the member, and when inserted into the long member, the elastic tongue piece is pressed against the long member. (For example, refer to Patent Document 2). That is, in the fore edge cover described above, an elastic tongue piece is provided when the cover member is provided with an elastic tongue piece in the insertion engagement portion inserted into the groove shape portion of the upper frame, and the insertion engagement portion is inserted into the groove shape portion. If the part is brought into pressure contact with the inner bottom surface of the groove-like part, it is possible to prevent a situation in which the part is inadvertently moved in the longitudinal direction of the upper frame.

JP 2009-144384 A Japanese Patent Laid-Open No. 9-210287

  By the way, in the fitting in which the shoji is opened and closed with respect to the opening frame, when the shoji is built in the opening frame, a situation may occur in which the upper collar contacts the fore cover. Therefore, when the fore cover is applied to a joinery, the fore cover is moved along the upper frame even when the upper collar comes into contact, for example, by pressing the elastic tongue piece against the inner bottom surface of the groove-like part with a greater force. It is necessary to prevent the situation of moving. In order to press the elastic tongue piece portion to the inner bottom surface of the groove-like portion with a larger force, the elastic tongue piece portion may be configured so as not to be bent easily by increasing the rigidity of the elastic tongue piece portion, for example. However, when the rigidity of the elastic tongue piece is improved, the operating force for moving the fore edge cover to a desired position with respect to the groove-like portion of the upper frame also increases, which is preferable in terms of workability. That's not true.

  In order to increase the pressure contact force of the elastic tongue piece without impairing the workability when mounting the fore cover, it is conceivable that the cover is inclined in advance. That is, if the elastic tongue piece portion is provided in an inclined state in advance, movement in the reverse direction can be more reliably prevented without greatly increasing the operating force when moving the fore edge cover. . However, when the elastic tongue piece portion is provided in an inclined state in advance, the direction in which the movement can be restricted with respect to the groove portion of the upper frame is limited, and the right side and the left side are restricted. It is necessary to configure a separate part from the one that restricts movement to In particular, there are many kinds of joinery, and there is a possibility that a manufacturing cost increases due to an increase in the number of handling parts.

  In view of the above circumstances, the present invention provides a fore cover that can more reliably prevent inadvertent movement along the longitudinal direction of a long member without impairing workability and without increasing the number of handling parts. The purpose is to provide.

  In order to achieve the above object, the fore edge cover according to the present invention is configured so that the cover member is attached when the cover member is attached to the groove-shaped portion with respect to the long member having the groove-shaped portion opening along the longitudinal direction. A plate-like portion that forms a plate shape, an insertion engagement portion that projects from the back surface of the plate-like portion, and a protruding end surface of the insertion engagement portion The insertion engaging portion is inserted into the groove-shaped portion of the long member so that the elastic tongue piece tilts in the inclination direction side. Thus, the plate-like portion covers the fore edge of the cover member and the outer surface area of the long member, and the protruding end portion of the elastic tongue piece tilts toward the inclined direction side, so that the groove-like portion is formed. The one along the groove-like portion is pressed against the inner bottom surface. The plate-like portion is configured in a quadrilateral quadrilateral shape with one side having a width substantially equal to the width of the outer surface region of the long member, and the insertion engaging portion. Is arranged such that the distance from two adjacent sides of the plate-like part matches the distance from one side edge of the outer surface region to the groove-like part in the long member, and the elastic tongue piece part is A first tongue piece extending in a direction intersecting with one of the two adjacent sides of the plate-like portion and a direction intersecting with the other of the two adjacent sides of the plate-like portion. And a second tongue piece.

  According to the present invention, the insertion engaging portion is arranged so that the distance from two adjacent sides of the plate-like portion matches the distance from one side edge of the outer surface region to the groove-like portion in the long member. is there. Therefore, it is possible to cover the outer surface area of the long member in both cases of moving along the one side and moving along the other side with respect to the groove-like portion of the long member. In addition, since the elastic tongue piece portion is constituted by the first tongue piece portion that intersects one side and the second tongue piece portion that intersects the other side with respect to two adjacent sides of the plate-like portion, depending on the insertion direction. It is possible to make the tongue piece portion act on the inner bottom surface of the groove-like portion.

  Further, the present invention is characterized in that in the fore edge cover described above, the first tongue piece portion and the second tongue piece portion are provided so as to extend along directions orthogonal to each other.

  According to this invention, when inserting into the groove-like part of the elongate member so that one tongue piece part acts, the other tongue piece part extends along the insertion direction. Does not increase the operating force.

  Further, the present invention is characterized in that in the fore edge cover described above, the first tongue piece portion and the second tongue piece portion are arranged in a plurality of rows on the protruding end surface of the insertion engagement portion.

  According to this invention, it is possible to more reliably regulate movement in the removal direction by increasing the contact area without increasing the plate thickness of each tongue piece.

  In the fore edge cover described above, the present invention is such that the total length along the extending direction of the first tongue piece portion and the total length along the extending direction of the second tongue piece portion are made to coincide with each other. Features.

  According to the present invention, the force for restricting movement in the removal direction can be set equally between when the first tongue piece is applied and when the second tongue piece is applied.

  According to the present invention, the insertion engagement portion is disposed so that the distance from two adjacent sides of the plate-like portion matches the distance from one side edge of the outer surface region to the groove-like portion in the long member. is there. Accordingly, the outer surface area of the long member and the fore edge of the cover member are covered in both cases of moving along one side with respect to the groove-shaped portion of the long member and moving along the other side. It becomes possible. In addition, since the elastic tongue piece portion is constituted by the first tongue piece portion that intersects one side and the second tongue piece portion that intersects the other side with respect to two adjacent sides of the plate-like portion, depending on the insertion direction. It is possible to make the tongue piece portion act on the inner bottom surface of the groove-like portion. Therefore, even when the elastic tongue piece is tilted to reliably prevent the movement in the reverse direction without increasing the operating force when moving to the desired position, the movement of the long member to one side is restricted. Parts to be used and those to be restricted from moving to the other can share parts, and the manufacturing cost can be reduced.

In this case, since the first tongue piece 40d1 is arranged along the insertion direction of the fore edge cover 40, the operation force thereof is not affected.

  Similarly, when the fore edge cover 40 is inserted into the upper frame 11 from the right side, the first tongue piece 40d1 is orthogonal to the insertion direction by setting the second reference side s2 to the base end side. The protruding end of the first tongue piece 40d1 is in pressure contact with the inner bottom surface 11g in a state of being inclined toward the opening end of the groove 11c. Therefore, the movement of the fore edge cover 40 in the removal direction is restricted by these first tongue pieces 40d1. In this case, since the second tongue piece portion 40d2 is arranged along the insertion direction of the fore edge cover 40, the operation force thereof is not affected.

  That is, even if the fore edge cover 40 is inserted into the groove-like portion 11c from the left or right direction with respect to the upper frame 11, the tongue pieces 40d1 and 40d2 according to the insertion direction act to restrict the movement in the removal direction. Will be. As described above, the first tongue piece portion 40d1 and the second tongue piece portion 40d2 are provided in an inclined state in advance. For this reason, when the fore edge cover 40 is inserted into the groove 11c, it is tilted in the inclined direction, and is pressed against the inner bottom surface 11g of the groove 11c with a larger force without increasing the operating force. Can do. Accordingly, for example, even when the shoji 20 is installed in the opening frame 10, even if the upper collar 21 comes into contact with the fore cover 40, the fore cover 40 and the cover member 30 extend along the extending direction of the upper frame 11. There is no danger of inadvertent movement.

  In the above-described embodiment, the fore cover 40 is inserted into the groove 11c together with the cover member 30 from the left and right end surfaces of the upper frame 11, but the present invention is not limited to this. For example, in the vicinity of the summing portion where the vertical rods 23 of the shoji 20 overlap each other, the engagement protrusion 11f provided on the groove-like portion 11c of the upper frame 11 is cut by a width slightly larger than the outer peripheral flange 40c of the fore cover 40. Then, the fore cover 40 may be inserted into the groove 11c from the prospective surface of the upper frame 11 through the cut portion, and then moved in the longitudinal direction to be engaged.

  In the above-described embodiment, the total length of the first tongue piece portion 40d1 and the second tongue piece portion 40d2 that restrict the movement of the fore edge cover 40 in the removal direction is made to coincide with each other. The ability to regulate the same is also the same, and the specifications for sharing in different ways can be matched. However, the present invention is not necessarily limited to this. Further, the first tongue piece portion 40d1 and the second tongue piece portion 40d2 are extended along the directions orthogonal to each other, but are not necessarily orthogonal, and a fore edge cover is inserted along one side. In this case, the first tongue piece portion and the second tongue piece portion may be provided such that one tongue piece portion acts and the other tongue piece portion acts when the fore edge cover is inserted along the other side. .
