Patent Description:
The present disclosure relates to the field of doors and windows, in particular to a translating structure, a sliding wheel and a fenestration assembly.

Sliding doors and windows are flexible, safe and durable. They move in one plane and occupy less space. Existing sliding doors and windows are usually provided with a sealing strip to maintain the indoor temperature in cold area. However, the movable panel will rub against the sealing strip when it is pushed and pulled, which will affect user experience. Furthermore, the sealing strip will be worn out after a long time of use hence the sealing effect is reduced and the room temperature cannot be maintained. <CIT> and <CIT> both disclose a translating structure for sliding doors and windows having a supporting frame, a guiding piece movable and restricted by the supporting frame, a guiding block mounted on and movable along with the guiding piece, a fixing frame equipped with rollers that is connected to the supporting frame. Such translating structures do not provide a sliding piece mounted in the fixing frame and partially inserted in the guiding groove and a sliding rod passing through the sliding piece and comprising two ends passing through the fixing frame and being fixedly connected to the supporting frame, wherein the sliding piece is forced to move along an axial direction of the sliding rod by the guiding groove when the guiding piece moves, and the fixing frame is forced to move along the axial direction of the sliding rod in a translational motion by movement of the sliding piece.

In light of the problems of the prior art, the present disclosure provides a translating structure, a sliding wheel, and a fenestration assembly.

A translating structure provided by the present disclosure includes:.

Further, the supporting frame includes an inner supporting frame, which includes a bottom plate and limiting plates disposed opposite to each other on two sides of the bottom plate. The bottom plate and the limiting plates define a sliding space, in which a part of the guiding piece is located, and the guiding piece is movable under restriction of the sliding space.

Further, two sides of the guiding piece are recessed inward to form an avoidance space for avoiding the limiting plates, and the limiting plates pass through the avoidance space so that a moving distance of the guiding piece is limited by cooperation between the avoidance space and the limiting plates.

Further, the supporting frame further includes an outer supporting frame, which includes two side plates. One of the side plates is fixed on one limiting plate on one side of the bottom plate, and the other one of the side plates is fixed on the other limiting plate on the other side of the bottom plate. One end of the sliding rod is fixedly connected to the one of the side plates, and the other end thereof is fixedly connected to the other one of the side plates.

Further, the fixing frame includes two side walls disposed opposite to each other, between which the rollers and the sliding piece are mounted. The sliding rod passing through the sliding piece has one end passing through one of the side walls and fixedly connected to the one of the side plates, and the other end passing through the other one of the side walls and fixedly connected to the other one of the side plates.

Further, the sliding rod includes a first shaft body. A through-hole is opened on the sliding piece, and the first shaft body passes through the through-hole with two ends thereof passing through the fixing frame and fixedly connected to the supporting frame. The first shaft body has a polygonal shape.

Further, the sliding rod includes two second shaft bodies, the sliding piece is provided with two through-grooves with symmetrical shapes, and the two second shaft bodies are disposed in parallel and pass through the two through-grooves and the fixing frame.

Each of the two second shaft bodies has a load bearing shaft passing through, and two ends of the load bearing shaft are extended out of each of the second shaft bodies and fixedly connected to the supporting frame.

Further, the sliding piece includes a sliding part and a limiting part provided on the sliding part. The guiding groove is arranged along a moving direction of the guiding block, and an angle between the guiding groove and the moving direction of the guiding block is an acute angle. The sliding rod passes through the sliding part, and the limiting part is inserted into the guiding groove, wherein a roller sleeve for cooperating with the guiding groove is sleeved on the limiting part.

The present disclosure further provides a sliding wheel, which includes any one of the above-mentioned translating structures.

The present disclosure further provides a fenestration assembly. The fenestration assembly includes a panel piece, a frame piece, and the above-mentioned sliding wheel. A supporting frame of the sliding wheel is fixedly mounted on the panel piece, and rollers of the sliding wheel are abutted on a guiding rail of the frame piece in order to roll on the guiding rail.

The panel piece is equipped with a driving mechanism, which is connected with the guiding piece of the sliding wheel through a transmission rod in order to force the guiding piece to move, thereby forcing the fixing frame to move in a translational motion. When the fixing frame moves in the translational motion, a sealing strip on the panel piece is pressed against the frame piece, and a sealing strip on the frame piece is pressed against the panel piece, or the sealing strip on the panel piece is separated from the frame piece, and the sealing strip on the frame piece is separated from the panel piece.

The advantageous effect of the present disclosure is that the panel piece of the fenestration assembly is slidably disposed on the frame piece through the sliding wheel which has the translating structure. In accordance with the translational motion of the fixing frame of the translating structure, the panel piece fixedly connected with the supporting frame moves in a translational motion in an opposite direction relative to the fixing frame, so that the sealing strip on the panel piece is pressed against the frame piece, and the sealing strip on the frame piece is pressed against the panel piece, or the sealing strip on the panel piece is separated from the frame piece, and the sealing strip on the frame piece is separated from the panel piece.

When the panel piece is to be pushed, the fixing frame moves in the translational motion to one side such that the sealing strip on the panel piece is separated from the frame piece, and the sealing strip on the frame piece is separated from the panel piece to prevent the sealing strips from rubbing against each other when pushing and pulling the panel piece. This requires less effort to push and pull the panel piece, hence the user experience is improved and the service life of the sealing strip is increased due to less abrasion.

When the panel piece is to be connected and sealed with the frame piece, the fixing frame moves to the other side, so that the sealing strip on the panel piece is pressed against the frame piece, and the sealing strip on the frame piece is pressed against the panel piece, hence the panel piece and the frame piece are connected and sealed.

In addition, the translating structure is easy to install, and has a simple structure and low manufacturing cost, it is convenient to operate, with high transmission efficiency and reliability, large bearing capacity, and an accurate transmission movement.
