Description

RELATED APPLICATION

The application claims the benefit of the Chinese Patent Application CN202211561002.9 filed Dec. 7, 2022, which is incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

The present invention relates to the field of retractable screen doors, and in particular, to an adjustable retractable screen door and a mounting accessory therefor.

BACKGROUND OF THE INVENTION

A sliding door is a commonly used door and refers to a door which may be pushed and pulled. A door leaf of the sliding door is horizontally moved in a push-pull way on a vertical plane so as to be opened or closed. To achieve functions such as ventilation and dust prevention in an open state of the sliding door, a sliding screen door is usually configured. Meanwhile, to mount the sliding screen door, a corresponding sliding structure may be configured on a sliding door frame.

However, a conventional sliding screen door also has certain defects. The sliding screen door will inevitably block a part of a door leaf to make them impassable (except that a non-sliding structure extends into a wall, so that the sliding screen door can slide into the wall). Furthermore, the sliding screen door cannot be retracted and can only be removed as a whole. A retractable screen door can well overcome the above-mentioned defects. However, a sliding door frame is required to be customized independently during the use of the retractable screen door. Otherwise, it cannot be mounted or put into use because of compatibility issues.

Therefore, when the corresponding sliding door frame is not designed independently, a retractable screen door compatible with most of existing sliding doors on the market or a mounting accessory for the universal assembly of the retractable screen door is required to overcome differences in sectional structures of door frame profiles from different suppliers—the differences in the sectional structures of the door frame profiles will lead to different heights of an inner edge of the door frame, and there will also be differences in spatial structures provided for mounting the screen door—and satisfy compatible mounting of the retractable screen door.

DETAILED DESCRIPTION OF THE EMBODIMENTS

To make the technical solutions of the present invention clearer, the present invention will be described below in conjunction with embodiments. Any solutions obtained by equivalently substituting and conventionally reasoning the technical features of the technical solutions of the present invention falls into the protection scope of the present invention.

Embodiment 1

As shown in FIGS. 1 to 6, the present embodiment discloses an adjustable retractable screen door applicable as a sliding door and is used for replacing an old-fashioned sliding screen door. This adjustable retractable screen door includes a retractable screen door 2, and the retractable screen door 2 includes a screen housing 28, a screen 45 (unshown) and a handle housing 29. The screen 45 is elastically rolled in the screen housing 28. An end of the screen 45 is connected to the handle housing 29. In an embodiment, an end of the screen housing 28 is sleeved with an end cap 1. The end cap 1 includes a housing 3 and a guide leg 4 which are configured on an integrated piece. The housing 3 sleeves an end of the retractable screen door 2. A screen outlet 8 allowing the screen to be pulled out of the retractable screen door 2 is configured on a side of the housing 3 to facilitate pulling out and withdrawing the screen. In an embodiment, the guide leg 4 and the screen outlet 8 are configured on a same side. A side of the guide leg 4 is provided with a stripe-shaped spring lock 9.

The opening or closing of the retractable screen door 2 is achieved by pushing and pulling the handle housing 29. To guide a pushing/pulling direction of the handle housing 29, in the present embodiment, the end cap 1 is connected to a screen channel 32 through the guide leg 4. The screen channel 32 is provided with an end cap connection channel 38 for connecting the end cap 1 and the screen channel 32 and a handle slide channel 39 (not shown in the figures) for guiding the pushing/pulling direction of the handle housing 29.

The guide leg 4 is inserted into an end of the end cap connection channel 38 so that a connection between the screen channel 32 and the end cap 1 is achieved. In an embodiment, the guide leg 4 is in clearance fit with the end cap connection channel 38. A locking slot 33 is configured on an outer wall of an end of the end cap to which the guide leg 4 and the connection channel 38 are connected. The locking slot 33 cooperates and is in clamping connection with the spring lock 9, so that the strength and stability of a connection between the screen channel 32 and the end cap 1 is attained. A handle slide body 40 is disposed on a side of an upper end of the handle housing 29. A handle slide body 40 is disposed on a side of a lower end of the handle slide body 40. The handle slide body 40 is in sliding fit with the handle slide channel 39 (not shown in the figures), so that a slidable connection between the handle housing 29 and the screen channel 32 and a guide for the pushing/pulling direction of the handle housing 29 is achieved.

The adjustable retractable screen door in the present embodiment is used for replacing the old-fashioned sliding screen door and is mounted on the sliding door frame. The screen door is closed immediately after being opened as required in use, so that the normal use of a door leaf cannot be hindered when the screen door is not used.

Embodiment 2

As shown in FIGS. 3 to 5, the present invention discloses an adjustable retractable screen door. The spring lock 9 includes a locking projection 20. The locking projection 20 engages the locking slot 33 for locking and connecting parts. The spring lock 9 may be configured on a single side or double sides as shown in FIG. 5. When the same material and specification are provided, compared with the spring locks 9 configured on double sides, the spring lock 9 configured on the single side is better in terms of maintaining the structural strength of the guide leg 4 and guaranteeing the stability of a connection between the end cap 11 and the screen channel 32. The spring locks 9 configured on double sides are better in terms of a locking effect, and also have a problem of high unlocking difficulty. Particularly, when they are applied to the mounting of the retractable screen door 2, a side of the mounted retractable screen door 2 may be close to a door leaf of a sliding door, thereby increasing the unlocking difficulty of the spring lock 9 on this side. To sum up, the spring lock 9 configured on the single side is more practical. The spring lock 9 is configured on a side away from the door leaf of the sliding door.

In an embodiment, a spring stripe 21 is configured between the spring lock 9 and the guide leg 4. The spring lock 9 is elastically connected to the guide leg 4 through the spring stripe 21. At least one spring stripe 21 is provided.

Embodiment 3

As shown in FIGS. 1, 2 and 6, the present invention discloses an adjustable retractable screen door having an adjustable function. A scheme for mounting the retractable screen door 2 can be adjusted according to a length specification of the retractable screen door 2, so that the purpose that a sliding door frame is adapted is achieved. A pair of the end caps 1 includes an upper end cap 101 which sleeves an upper end of the screen housing 28 and a lower end cap 102 which sleeves a lower end of the screen housing 28. The screen channel 32 includes a top screen channel 321 which is connected to the upper end cap 101 and a lower screen channel 322 which is connected to the lower end cap 102. The handle slide channel 39 includes a screen slide opening slot 43 and a slide channel 44 adjacent to the screen slide opening slot 43. A height of the screen slide opening slot 43 along a vertical direction is less than a height of the slide channel 44 along a vertical direction. The handle slide body 40 is in sliding fit with one of the screen slide opening slots 43 and with the slide channel 44.

The handle slide body 40 which is located on an upper end of the handle housing 29 is a handle housing top slide 41. The handle slide body 40 which is located on a lower end of the handle housing 29 is a handle housing lower slide 42. The screen slide opening slot 43 which is located on the top screen channel 321 is an upper weatherstrip slot 431. The slide channel 44 which is located on the top screen channel 321 is a top slide channel 441. The screen slide opening slot 43 which is located on the lower screen channel 322 is a lower weatherstrip slot 432. The slide channel 44 which is located on the lower screen channel 322 is a lower slide channel 442. Four schemes (as shown in FIG. 6) are proposed for a way of sliding fit between the handle slide body 40 and the handle slide channel 39 and are specifically described as follows.

Q1: The handle housing top slide 41 is slidably configured on the top slide channel 441. The handle housing lower slide 42 is slidably configured on the lower weatherstrip slot 432.

Q2: The handle housing top slide 41 is slidably configured on the top slide channel 441. The handle housing lower slide 42 is slidably configured on the lower slide channel 442.

Q3: The handle housing top slide 41 is slidably configured on the upper weatherstrip slot 431 The handle housing lower slide 42 is slidably configured on the lower weatherstrip slot 432.

Q4: The handle housing top slide 41 is slidably configured on the upper weatherstrip slot 431. The handle housing lower slide 42 is slidably configured on the lower slide channel 442.

In these four schemes, both of the upper end cap 101 and the lower end cap 102 cannot be separated from the upper and lower ends of the screen housing 28.

When the height of the sliding door frame is invariable, these schemes can be selected according to a vertical length condition of the retractable screen door 2. When the vertical length of the retractable screen door 2 is largest—equal to a vertical length between the upper weatherstrip slot 431 and the lower weatherstrip slot 432, and marked as d1)—the scheme Q3 is appropriate. When the vertical length of the retractable screen door 2 is largest—less than or equal to a vertical length between the top slide channel 441 and the lower slide channel 442, and greater than a vertical length between the top slide channel 441 and the lower weatherstrip slot 432 or a vertical length between the upper weatherstrip slot 431 and the lower slide channel 442, and marked as d2—the scheme Q2 is appropriate. When the vertical length of the retractable screen door 2 is moderate—greater than a vertical length between the upper weatherstrip slot 431 and the lower weatherstrip slot 432, and less than or equal to a vertical length between the top slide channel 441 and the lower weatherstrip slot 432 or a vertical length between the upper weatherstrip slot 431 and the lower slide channel 442, and marked as d3—either the scheme Q1 or Q4 is appropriate.

When the vertical length of the retractable screen door 2 is definite, by selecting the way of sliding fit between the handle slide body 40 and the handle slide channel 39, the adjustable retractable screen door can be adjusted in vertical length so as to adapt to sliding doors with different door frame heights.
