Abstract

Official abstract text for this publication.

A clip for attachment of a floor carpet includes a male member having a lower flange portion, and a shaft portion projecting from the lower flange portion; and a female member having a cylindrical portion to which the shaft portion is inserted, an upper flange portion projecting around an outer periphery of the cylindrical portion, and an engaging portion at an inner periphery of the cylindrical portion. The male member also includes a hole portion penetrating through the lower flange portion and the cylindrical portion, engaging projections formed around an outer periphery of the shaft portion, and a regulation member inserted into the hole portion. In case the male member is inserted into the female member to engage the engaging projections with the engaging portion and the regulation member is inserted into the hole portion, the regulation member prevents the engaging projections from being disengaged from the engaging portion.

First claim

Opening claim text (preview).

What is claimed is: 1. A clip for attachment of a floor carpet, comprising: a male member having a lower flange portion, and a shaft portion projecting from an upper surface of the lower flange portion, and a female member having a cylindrical portion to which the shaft portion is inserted, and an upper flange portion projecting around an outer periphery of the cylindrical portion, wherein the clip is configured to be attached to the floor carpet held between the lower flange portion and the upper flange portion by inserting the shaft portion to an insertion hole formed in the floor carpet from a hole lower side to a hole upper side and engaging the shaft portion penetrating through the insertion hole with the cylindrical portion so that an article mounted on an upper surface of the floor carpet is fixed by the cylindrical portion of the male member, the female member includes an engaging portion at an inner periphery of the cylindrical portion, and the male member includes a hole portion penetrating through the lower flange portion and the cylindrical portion in an axial direction, engaging projections formed around an outer periphery of the shaft portion to project therefrom, a regulation member to be inserted into the hole portion, and a hinge bendably connecting the regulation member to the lower flange portion, said regulation member, when the male member is inserted into the female member to engage the engaging projections with the engaging portion and the regulation member is inserted into the hole portion, preventing the engaging projections from being disengaged from the engaging portion. 2. A clip according to claim 1 , wherein the shaft portion of the male member includes a plurality of divided shaft pieces divided by the shaft portion. 3. A clip according to claim 1 , wherein the regulation member includes a claw engaging an engaging portion formed at the lower flange portion of the male member. 4. A clip according to claim 1 , wherein the shaft portion of the male member includes the engaging projections arranged in the shaft direction, and the cylindrical portion of the female member includes a lower projecting portion projecting downwardly from a lower surface of the lower flange portion and having the engaging portion on an inner periphery thereof. 5. A clip for attachment of a floor carpet, comprising: a male member having a lower flange portion, and a shaft portion projecting from an upper surface of the lower flange portion, and a female member having a cylindrical portion to which the shaft portion is inserted, and an upper flange portion projecting around an outer periphery of the cylindrical portion, wherein the clip is configured to be attached to the floor carpet held between the lower flange portion and the upper flange portion by inserting the shaft portion to an insertion hole formed in the floor carpet from a hole lower side to a hole upper side and engaging the shaft portion penetrating through the insertion hole with the cylindrical portion so that an article mounted on an upper surface of the floor carpet is fixed by the cylindrical portion of the male member, the female member includes an engaging portion at an inner periphery of the cylindrical portion, and the male member includes a hole portion penetrating through the lower flange portion and the cylindrical portion in an axial direction, engaging projections formed around an outer periphery of the shaft portion to project therefrom, a regulation member to be inserted into the hole portion, and a connecting piece bendably connecting the regulation member to the lower flange portion, said regulation member, when the male member is inserted into the female member to engage the engaging projections with the engaging portion and the regulation member is inserted into the hole portion, preventing the engaging projections from being disengaged from the engaging portion. 6. A clip for attachment of a floor carpet, comprising: a male member having a lower flange portion, and a shaft portion projecting from an upper surface of the lower flange portion, and a female member having a cylindrical portion to which the shaft portion is inserted, and an upper flange portion projecting around an outer periphery of the cylindrical portion, wherein the clip is configured to be attached to the floor carpet held between the lower flange portion and the upper flange portion by inserting the shaft portion to an insertion hole formed in the floor carpet from a hole lower side to a hole upper side and engaging the shaft portion penetrating through the insertion hole with the cylindrical portion so that an article mounted on an upper surface of the floor carpet is fixed by the cylindrical portion of the male member, the female member includes an engaging portion at an inner periphery of the cylindrical portion, and the male member includes a hole portion penetrating through the lower flange portion and the cylindrical portion in an axial direction, engaging projections formed around an outer periphery of the shaft portion to project therefrom, and a regulation member to be inserted into the hole portion and having a claw engaging an engaging portion formed at the lower flange portion of the male member and defined by an edge portion of the hole portion and a plurality of slits extending from the hole portion, said regulation member, when the male member is inserted into the female member to engage the engaging projections with the engaging portion and the regulation member is inserted into the hole portion, preventing the engaging projections from being disengaged from the engaging portion.
