The present invention relates to a device for shielding a door seam, and more particularly to a magnetic attraction threshold which shields or opens the door seam by ways of a door leaf.
A conventional door leaf rotates relative to a door frame. To rotate the door leaf smoothly, a size of the door frame is more than that of the door leaf, so a door seam exists between the door leaf and a ground, and sounds, smokes, dusts, bugs or waters enter into a room via the door.
To overcome above-mentioned problem, an electric lift threshold is disclosed in U.S. D738,532 S and contains a hollow accommodation holder and at least one electric moving device accommodated in the accommodation holder. The electric moving device includes a drive rod and a stopper having a stop sheet and at least one fixing fence. The at least one fixing fence extends from a bottom of the stop sheet, and the at least one fixing fence has a first fringe and a second fringe symmetrical to the first fringe. The accommodation holder further includes a first groove and a second groove, wherein the first groove has a first opening defined on a top thereof, the second groove has a second opening defined on a top thereof, wherein the first groove and the second groove are symmetrically formed on the accommodation holder. The first fringe is inserted into the first groove via the first opening, and the second fringe is inserted into the second groove via the second opening. Thereby, the electric moving device is opened to actuate the drive rod to push the stopper toward the open segment of the accommodation holder at a distance and suspends. After opening the electric moving device once more, the drive rod is actuated to drive the stopper to move back to an original position.
However, the electric lift threshold is driven to extend out of or retract into a closing device to close the door seam by using a complicated structure. The electric lift threshold is not environmentally friendly by ways of a power. Furthermore, when the door has multiple door leaves, a slit exists between any two adjacent door leaves, and it is not suitable to fix the drive rod between the door leaves. When multiple electric lift threshold ate fixed on multiple door leaves respectively, the multiple closing device close the door seams from bottoms of the multiple door leaves individually after closing the multiple door leaves, the multiple closing devices drop from the multiple door leaves to close the multiple door seams respectively, but slits exist among the multiple closing devices, the sounds, bugs, smokes, and waters enter into the room easily.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary aspect of the present invention is to provide a magnetic attraction threshold which is mounted on any desired position of a door so as to shield a door seam and to overcome above-mentioned defects.
To obtain the above aspects, a magnetic attraction threshold provided by the present invention contains: an accommodation holder, a stopper, and at least one magnetic element.
The base includes an open segment, a first groove, and a second groove. The first groove includes a first opening defined on a top thereof, the second groove includes a second opening formed on a top thereof, and the first groove and the second groove are symmetrically formed inside the hollow accommodation holder.
The stopper includes a stop sheet, a first fixing fence, and a second fixing fence. The first fixing fence and the second fixing fence extend from a bottom of the stop sheet respectively, and the stop sheet includes a trench formed on the bottom thereof and configured to accommodate the at least one magnetic element.
The stopper is connected in the accommodation holder so that the first fixing fence and the second fixing fence are movably received in the accommodation holder, and the stop sheet is adjacent to the open segment.
The first fixing fence is movably inserted into the first groove via the first opening, and the second fixing fence is movably inserted into the second groove via the second opening.
Thereby, the at least one magnetic element is magnetically attracted by at least one magnetic attraction metal or at least one hetero magnetic element so as to actuate the stopper to extend out of the open segment of the accommodation holder. Hence, the stopper shields or closes a door leaf or insulates sounds of the door leaf.
The magnetic attraction threshold is connected on the door which includes a door frame and the door leaf. The door leaf is movably connected inside the door frame. The magnetic attraction threshold is connected with the door frame and the door leaf A width of the magnetic attraction threshold matches with that of the door leaf, and an interior of a bottom of the door leaf is connected with the at least one magnetic attraction metal (or the hetero magnetic element) so that the door leaf is closed to the door frame. The at least one magnetic attraction metal (or the hetero magnetic element) corresponds to a top of the at least one magnetic element. The at least one magnetic element is magnetically attracted by the at least one magnetic attraction metal (or the at least one hetero magnetic element) to actuate the stopper to abut against a bottom of the door leaf upward, the stop sheet closes the bottom of the door leaf, and the first fixing fence and the second fixing fence shield a gap between the door leaf and a floor. Thereby, the magnetic attraction threshold shields and closes the gap or insulates the sounds. When the door leaf is opened to be away from the door frame, the at least one magnetic attraction metal (or the hetero magnetic element) moves away from the at least one magnetic element, and the stopper drops and is accommodated in the accommodation holder.
In another embodiment, a magnetic attraction threshold contains: an accommodation holder, a stopper, and at least one magnetic attraction metal.
The base includes an open segment, a first groove, and a second groove. The first groove includes a first opening defined on a top thereof, the second groove includes a second opening formed on a top thereof, and the first groove and the second groove are symmetrically formed inside the hollow accommodation holder.
The stopper includes a stop sheet, a first fixing fence, and a second fixing fence. The first fixing fence and the second fixing fence extend from a bottom of the stop sheet respectively, and the stop sheet includes a trench formed on the bottom thereof and configured to accommodate the at least one magnetic attraction metal.
The stopper is connected in the accommodation holder so that the first fixing fence and the second fixing fence are movably received in the accommodation holder, and the stop sheet is adjacent to the open segment.
The first fixing fence is movably inserted into the first groove via the first opening, and the second fixing fence is movably inserted into the second groove via the second opening.
Preferably, the magnetic attraction threshold is connected on a door which includes a door frame and the door leaf, wherein the door leaf is movably connected inside the door frame, the magnetic attraction threshold is connected with the door frame and the door leaf, and an interior of a bottom of the door leaf is connected with at least one magnetic element.
The accommodation holder and the stopper of the magnetic attraction threshold are fixed in the ground trough below the door so as to actuate the stopper to extend out of the door seam in a magnetic attraction effect. Preferably, the magnetic attraction threshold is fixed in the ground trough to match with the door with multiple door leaves so as to completely close the door seam among bottoms of the multiple door leaves and the ground, thus insulating the sounds and stopping smokes, insects, waters, and dusts.
When opening the door, the stopper is accommodated in the accommodation holder by opening and closing the door leaf Preferably, the magnetic attraction threshold is fixed on a slit of an upper portion of the door frame and the door leaf. Alternatively, the magnetic attraction threshold is fixed on at least two door leaves so as to shield a slit of the at least two door leaves.
