Description

RELATED APPLICATION

The application claims the benefit of the Chinese Patent Application CN202211521221.4 filed Nov. 30, 2022, which is incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

The present invention relates to the field of doors and windows of buildings, and in particular, to door leaves and doors incorporating the door leaves.

BACKGROUND OF THE INVENTION

A door leaf is a door component which can be opened or closed, and is usually applied to spatial isolation and conditional passage between interiors of buildings or between the interior and the exterior of a building. According to different opening and closing modes of doors, common doors include a side-hung door and a sliding door. A door leaf of the side-hung door rotates along a pivot on a vertical edge so as to be opened towards the interior or the exterior, and a door leaf of the sliding door is opened and closed by horizontal movement on a vertical plane in a sliding way.

At present, basic structures of door leaves on the market are quite different according to the different opening and closing modes of doors. That is, the door leaf with the same basic structure cannot be applied to the production and assembly of the side-hung door and the sliding door at the same time to create a universal product. Therefore, additional investments in molds, tools and devices are required, which increases the enterprise cost. Therefore, it is necessary to design a door leaf which can satisfy application requirements of the side-hung door and the sliding door. Further, it is also necessary to lower the difficulty in assembly as much as possible to simplify an assembling process, increase the production efficiency and reduce the cost.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In order to make the technical solutions of the present invention clearer, the present invention will be further 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 fall into the protection scope of the present invention.

Embodiment 1

As shown in FIGS. 1 to 4, the present embodiment discloses a door leaf applicable to the universal mounting of a side-hung door and a sliding door. Specifically, the door leaf includes a frame 1 and a panel 2 which fits in the frame 1. The frame 1 is formed by connecting a plurality of universal profiles 3. The universal profile 3 is provided with a plurality of component slots 4 for connecting an auxiliary profile and for assembling a door-leaf accessory. The universal profiles 3 in the present embodiment have the characteristic of universality and can be adaptively equipped with most of auxiliary profiles and door-leaf accessories, thereby achieving the universal mounting of the side-hung door and the sliding door.

The universal profile 3 in the present embodiment includes a profile main body 5, a plurality of inner-side outer edges 6 which extend to two ends of the profile main body 5 and a plurality of outer-side outer edges 7 which extend to two ends of the profile main body 5. To reduce the production cost and satisfy a requirement for lightweight, the profile main body 5 has a hollow cross section. The inner-side outer edge 6 has a hollow cross section. The outer-side outer edge 7 has a hollow cross section, with reinforcement ribs 12 configured therein to improve the structural strength thereof.

As shown in FIGS. 3 and 4, the plurality of inner-side outer edges 6, which are symmetrically configured, and an end surface (an end surface on the left as shown in FIGS. 3 and 4) on one side of the profile main body 5 form an inner-side mounting channel 8 which can be used for assembling various auxiliary profiles. Similarly, the plurality of outer-side outer edges 7, which are also symmetrically configured, and an end surface (an end surface on the right as shown in FIGS. 3 and 4) on another side of the profile main body 5 form an outer-side mounting channel 9. Furthermore, an inner side surface of the inner-side outer edge 6 is symmetrically provided with a component slot 4. An inner side surface of the outer-side outer edge 7 is symmetrically provided with a component slot 4. The component slot 4 is used for mounting and assembling the various corresponding auxiliary profiles and door-leaf accessories.

The universal profiles in the present embodiment may be made of a metal (such as aluminum alloy and stainless steel) and may also be made of thermoplastic plastics. When being combined to form the frame 1, the plurality of universal profiles 3 may be connected in a threaded connection or welding (metal welding and hot-melt welding) way and may be reinforced in a way of additionally mounting or placing reinforced corner pieces 36 (inner reinforced corner pieces and/or outer reinforced corner pieces) on inner or outer edges of four corners of the frame 1 (as shown in FIG. 7).

As shown in a sectional view of a universal profile in FIG. 3, widths (horizontal lengths in FIG. 3) and heights (vertical lengths in FIG. 3) of the profile main body 5, the inner-side outer edges 6 and the outer-side outer edges 7 can be adjusted according to actual requirements. The universal profiles 3 in the present embodiment are used for assembling the door leaf and can be adaptively assembled with the auxiliary profile and the door-leaf accessory with the component slots 4, thereby satisfying application requirements of the side-hung door and the sliding door.

Embodiment 2

As shown in FIG. 3, the present embodiment discloses a door leaf in which a cross section of the profile main body 5 is a rectangle. The rectangle's diagonals intersect at a central point O-1 of the profile main body 5. A line of symmetry L-1 of the universal profile 3 passes through the central point O-1. A plurality of first reinforcement ribs 51, which are symmetric with respect to the line of symmetry L-1, are configured inside the profile main body 5. The plurality of outer-side outer edges 7 are symmetrically configured with respect to the line of symmetry L-1. A plurality of second reinforcement ribs 52 are symmetrically configured inside a hollow space within the plurality of outer-side outer edges 7 so that profile structures of the profile main body 5 and the outer-side outer edges 7 are reinforced. A hollow space within the profile main body 5 is compartmentalized, by the plurality of first reinforcement ribs 51, into two symmetric first cavities 61 and a second cavity 62 sandwiched by the two first cavities 61. The hollow space within the outer-side outer edge 7 is compartmentalized, by the second reinforcement rib 52, into a third cavity 63 and a fourth cavity 64 adjacent to the third cavity 63. A fifth cavity 65 is configured in a hollow space in the inner-side outer edge 6.

The first reinforcement ribs 51 are disposed in parallel to the line of symmetry L-1. A plane on which the second reinforcement rib 52 is located is perpendicular to the line of symmetry L-1. The reinforcement ribs in the universal profiles 3 are distributed vertically and horizontally, so as to guarantee the structural strength of the universal profiles 3 in a plurality of directions. A cross-sectional area of the second cavity 62 is greater than a cross-sectional area of any one of the first cavity 61, the third cavity 63, the fourth cavity 64 and the fifth cavity 65.

In an embodiment, a first depth along a direction in which an opening position of the inner-side mounting channel 8 extends to the central point O-1 is a depth of the inner-side mounting channel 8. A second depth along a direction in which an opening position of the outer-side mounting channel 9 extends to the central point O-1 is a depth of the outer-side mounting channel 9. It can be seen from the figure that the first depth is less than the second depth. Therefore, no reinforcement ribs are disposed in the inner-side outer edges. Moreover, the second reinforcement rib 52 is located at a central position on the outer-side outer edge 7, so that the structural strength and stability of the outer-side outer edge 7 are improved evenly. Furthermore, the outer-side mounting channel 9 is divided into an outer-side mounting channel outer end 91 and an outer-side mounting channel inner end 92 by the plane on which the second reinforcement rib 52 is located. A width of the outer-side mounting channel outer end 91 is greater than a width of the outer-side mounting channel inner end 92. The outer-side mounting channel outer end 91 and the outer-side mounting channel inner end 92 are connected by an oblique transition segment 93 whose obliqueness transitions smoothly. This structural feature not only lies in satisfying a design requirement for the profiles but positions where the profiles match the second reinforcement ribs 52 can be beneficial to reinforce the structural strength of the outer-side mounting channel 9.

Embodiment 3

In an embodiment shown in FIG. 4, a cross section of the profile main body 5 in the door leaf is a rectangle. The rectangle's diagonals intersect at a central point O-2 of the profile main body 5. A line of symmetry L-2 of the universal profile 3 passes through the central point O-2. The inner-side outer edge 6 and the outer-side outer edge 7 which is on the same side as the inner-side outer edge 6 are interconnected and communicating. A hollow structure formed by the inner-side outer edge 6 and the outer-side outer edge 7 is compartmentalized into a plurality of chambers by a plurality of third reinforcement ribs 53.

The inner-side mounting channel 8 is internally provided with a first bottom plate 94, and the outer-side mounting channel 9 is internally provided with a second bottom plate 95. The first bottom plate 94, which is spaced apart from and disposed in parallel to one side of the profile main body 5, forms a sixth cavity 66. The second bottom plate 95, which is disposed on another side of the profile main body 5, forms a seventh cavity 67.

The second bottom plate 95, a middle portion of which bends towards the profile main body 5, is connected with a side of the profile main body 5 to form an integrated piece with the profile main body 5. The integrated piece divides the seventh cavity 67 into two independent cavities. The two independent cavities formed by the seventh cavity 67 are symmetrically disposed with respect to the line of symmetry L-2.

Embodiment 4

In an embodiment of the door leaf shown in FIG. 3, a plurality of centerline grooves are formed in a middle portion of an end surface on two sides of the universal profile 3. The plurality of centerline grooves include a first centerline groove 10 and a first centerline groove 11. The first centerline groove 10 is configured on the inner-side mounting channel 8. The first centerline groove 11 is configured on the outer-side mounting channel 9. Such configuration functions for positioning of riveting points, so that screws can be more easily screwed in the universal profiles 3 when the auxiliary profile is connected or the door-leaf accessory is assembled later. So difficulty in assembly is mitigated.

Embodiment 5

An embodiment of the door leaf is shown in a sectional view of a universal profile in FIGS. 3 and 4. In the case that the universal profiles 3 have the same length and width, the width of the outer-side outer edge 7 in FIG. 3 is obviously greater than the width of the outer-side outer edge 7 in FIG. 4. The depth of the outer-side mounting channel 9 in FIG. 3 is obviously greater than the depth of the outer-side mounting channel 9 in FIG. 4. This is so because the universal profile 3 in FIG. 3 is mainly used as a vertically-disposed universal profile which is usually mounted on the left or right side of the frame 1 and is vertically disposed. The widened outer-side outer edges 7 and the deepened outer-side mounting channel 9 are more beneficial to the assembly of the door-leaf accessory such as a door lock. Of course, it can also be used as a horizontally-disposed universal profile. In contrast, the universal profile 3 in FIG. 4 is mostly used as a horizontally-disposed universal profile which is usually mounted on the upper or lower side of the frame 1 and is horizontally disposed. The outer-side outer edges 7 and the outer-side mounting channel 9 are better suitable for the assembly of such components as auxiliary profile for sealing dust prevention.

FIGS. 3 and 6 show a sectional view of a universal profile. The universal profiles 3 have the same length and width. The inner-side outer edges 6 of the universal profile 3 in FIG. 6 are combinable and are detachably mounted. A side of the inner-side outer edge 6 which faces the profile main body 5 includes a clamping strip. The profile main body 5 includes a clamping slot to match the clamping strip. The inner-side outer edge 6 is detachably connected to the profile main body 5 by clamping connection between the clamping strip and the clamping slot. When the universal profile 3 in FIG. 6 is used as a vertically-disposed universal profile or a horizontally-disposed universal profile, the panel 2 disposed in the frame 1 is convenient to mount, dismount and replace. It is also easy to clean, care and maintain the door leaf.

Embodiment 6

As shown in FIGS. 8 to 11, the side-hung door includes a side-hung door frame 14 and a pair of door leaves for connecting to and for matching the side-hung door frame 14. The universal door leaves have the technical features in embodiment 1 and embodiment 5 and are applicable to the combined mounting of the side-hung door.

Specifically, a side of the door leaf is hinged to the side-hung door frame 14 through a hinge 15. The frame 1 is designed to be shaped like a frame and is formed by combining a pair of the horizontally-disposed universal profiles 3 and a pair of the vertically-disposed universal profiles 3. The panel 2 is mounted into the frame 1 through the inner-side mounting channel 8.

The outer-side outer edge 7 of the horizontally-disposed universal profile 3 is in clamping connection to a leaf-edge sealing cover plate 16 through a component slot 4 so that the upper and lower sides of a side-hung door leaf are sealed. The outer-side outer edge 7 of the universal profile 3 which is hinged to the side-hung door frame 14 is in clamping connection to a leaf-edge sealing cover plate 16 through a component slot 4 so that the side of the side-hung door leaf which meets the door frame when the door is closed is well sealed.

To achieve an opening/closing function of the side-hung door, the side-hung door includes a matching pair of the door leaves. A pair of the outer-side outer edges 7 on the universal profiles 3 of the matching pair of the door leaves are meant to meet each other when the side-hung door is closed. A first one of the pair of the outer-side outer edges 7 is connected to a leaf-edge sealing cover plate 16 through a component slot 4 that is provided on the first one of the pair of the outer-side outer edges 7. A second one of the pair of the outer-side outer edges 7 is connected to a astragal 17 through a component slot 4 that is provided on the second one of the pair of the outer-side outer edges 7. The leaf-edge sealing cover plate 16 is in clamping connection with the universal profile 3 through a component slot 4 and is screwed. A middle portion of the leaf-edge sealing cover plate 16 is provided with a side-hung door lock 18. The astragal 17 is fixedly screwed to the door leaf. A middle portion of the astragal 17 is provided with a universal latch 19 to match the side-hung door lock 18.

So far, door frame connection, side seal and opening/closing accessory assembly for the side-hung door in the present embodiment are completed. The universal combined mounting of the side-hung door is achieved.

Embodiment 7

Based on embodiment 6, the present embodiment provides a side-hung door, in which a bottom of an outdoor side (the right shown in FIG. 9) of the side-hung door frame 14 is provided with a cover 20. An elastic sealing strip 21 is provided on a side surface of the cover 20 which is adjacent to the door leaf.

Embodiment 8

As shown in FIGS. 12 to 16, the present embodiment discloses a side-hung door which is a single-sided leaf opened side-hung door. In a pair of universal door leaves, one door leaf is fixed, and the other door leaf can be freely opened or closed. The pair of universal door leaves include an operable door leaf 41 which can be openable/closable and a fixed door leaf 42. The side-hung door frame 14 is internally provided with a vertically-disposed mullion 43. Upper and lower ends of the mullion 43 are fixedly connected to the side-hung door frame 14. The inside of the side-hung door frame 14 is segmented into two mounting areas in which the operable door leaf 41 and the fixed door leaf 42 are respectively mounted.

An end of the operable door leaf 41 is in hinged connection to the side-hung door frame 14 through a hinge 15. The other end of the operable door leaf 41 is equipped with a side-hung door lock 18. The fixed door leaf 42 is riveted and fixed to the side-hung door frame 14 and to the mullion 43 through screws. The side of the mullion 43 which faces to the operable door leaf includes a universal latch 19 to match the side-hung door lock 18.

As shown in FIGS. 12 and 13, the relationship between the widths of the frames of the operable door leaf 41 and the fixed door leaf 42 is customizable. The side-hung doors may be categorized into narrow-side leaf unopened side-hung doors (as shown in FIG. 12) and equal-width leaf unopened side-hung doors (as shown in FIG. 13).
