Description

Technical Field

[0001] This utility model relates to the field of shower room technology, and in particular to a door frame structure with hidden hinges and a shower room. Background Technology

[0002] Existing concealed hinges on the market are fixed to two metal profiles or to one side of a profile and the other side of a wooden / aluminum door frame, making them invisible from the front. Doors using this structure can open 90°. However, current concealed hinges are fixed to two horizontally parallel profiles, leaving a gap between them, making a complete seal difficult. In shower enclosures, water can leak through this gap. Furthermore, doors using concealed hinges can only rotate 90°, which is limiting in practical use. For example, in shower enclosures, opening the door for ventilation when the shower is not in use can obstruct the user's view. Utility Model Content

[0003] This utility model aims to at least partially solve one of the aforementioned technical problems in the related art. To this end, this utility model proposes a door frame structure with a hidden hinge.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] This utility model also proposes a shower room with a door frame structure.

[0006] According to a first aspect of the present invention, a door frame structure with a concealed hinge includes a first door frame and a concealed hinge. The first door frame has a first receiving cavity penetrating its rear wall and right wall. The concealed hinge includes a first hinge body, a second hinge body, and a pivot. The first hinge body has a hinge notch and is fitted into the first receiving cavity so that the first hinge body is concealed by the front wall of the first door frame. The second hinge body includes an L-shaped connecting frame and a mounting block. The L-shaped connecting frame includes a first connecting edge and a second connecting edge that are perpendicular to each other. The first connecting edge is located away from the front wall of the first door frame. A bushing is formed at one end of the second connecting edge. The mounting block is connected to the end of the second connecting edge away from the first connecting edge. The mounting block has a mounting surface for connecting with the door body. The mounting surface is perpendicular to the first connecting edge and faces the side where the bushing is located. The bushing is embedded in the hinge notch. The second hinge body is rotatably connected to the first hinge body by passing through the hinge notch and the bushing via the pivot. The second hinge body can rotate 180° around the pivot from the first position to the second position, so that the mounting block rotates from the rear of the first door frame to the front of the first door frame.

[0007] The door frame structure according to the embodiment of this utility model has at least the following beneficial effects:

[0008] Unlike conventional concealed hinges that are fixed to two horizontally arranged door frames, this invention's concealed hinge can be applied to two door frames arranged front to back. One door frame can be hidden behind the other, so only one door frame is visible from the front, with no gaps, resulting in a more aesthetically pleasing appearance. The lever arm of a conventional concealed hinge is 180° when the door is closed, while the lever arms of the two main bodies of this invention are 90° when the door is closed. The door connected to the mounting surface is a sliding door. When the second hinge body is in the first position, the sliding door is in the closed state, located behind the first door frame. When the second hinge body is in the second position, the sliding door is in the fully open state, bypassing the first door frame and reaching its front. The door using this new type of hidden hinge can open 180°. When the door is open, it can overlap with the fixed glass of the shower room. When the shower room is not in use, opening the door for ventilation will not obstruct the user. The arrangement of the two door frames front and back also solves the problem of poor waterproofing of traditional hidden hinges and water easily flowing out from the gap between the two door frames arranged on the left and right.

[0009] According to some embodiments of this utility model, a second door frame is also included. The second door frame is provided with a second accommodating cavity for installing the mounting block and a first mounting groove for installing the door body. The mounting block is embedded in the second accommodating cavity. A screw mounting hole is provided on the mounting surface. The mounting block is connected to the second door frame by screws. The groove direction of the first mounting groove is the same as the orientation of the mounting surface. The shortest distance L1 from the axis of the rotating shaft to the second door frame is greater than the distance L2 from the axis of the rotating shaft to the front wall of the first door frame. The second hinge body can rotate 180° around the rotating shaft from the first position to the second position, so that the second door frame rotates from the rear of the first door frame to the front of the first door frame.

[0010] According to some embodiments of the present invention, the hidden hinge further includes two wear-resistant pads, which are sleeved on the pivot and located at the upper and lower ends of the bushing, respectively, and sandwiched between the bushing and the first hinge body.

[0011] According to some embodiments of the present invention, the first hinge body includes a main body and two mounting plate parts. The hinge notch is provided in the main body, and the two mounting plate parts are respectively provided at the upper end and lower end of the main body. The main body is embedded in the first accommodating cavity, and the mounting plate parts are closely attached to the rear wall or right wall of the first door frame. The mounting plate parts are installed on the rear wall or right wall of the first door frame by screws.

[0012] According to some embodiments of the present invention, the rear wall or right wall of the first door frame is partially recessed inward to form a groove that matches the mounting plate portion, and the mounting plate portion is embedded in the groove.

[0013] According to some embodiments of the present invention, the cross-section of the first door frame is L-shaped and is composed of a first frame and a second frame that are perpendicular to each other. The first frame and the second frame are an integral structure. The second frame is located on the left side of the rear side of the first frame. The first accommodating cavity is provided on the first frame. The second frame is provided with a second mounting groove for installing the door. The groove opening direction of the second mounting groove is opposite to the groove opening direction of the first mounting groove. The second door frame is located behind the first frame and to the right of the second frame.

[0014] According to some embodiments of the present invention, the hidden hinge further includes a first positioning member, which is installed on the side wall of the hinge notch. When the second hinge body is in the first position, the mounting block is located to the left rear of the pivot, and the second connecting edge abuts against the first positioning member.

[0015] According to some embodiments of the present invention, the L-shaped connecting frame is provided with an avoidance chamfer at the corner where the first connecting edge and the second connecting edge meet, so as to prevent the second hinge body from being blocked by the first positioning member when rotating to the second position.

[0016] According to some embodiments of the present invention, the hidden hinge further includes a second positioning member, which is installed on the second connecting edge. When the body of the second hinge is in the second position, the second positioning member abuts against the first door frame.

[0034] Reference Figure 1-6 A door frame structure with a hidden hinge includes a first door frame 100 and a hidden hinge 200. The first door frame 100 has a first receiving cavity 130 penetrating its rear wall 110 and right wall 120. The hidden hinge 200 includes a first hinge body 210, a second hinge body 220, and a pivot 230. The first hinge body 210 has a hinge notch 211 and is fitted into the first receiving cavity 130 so that the first hinge body 210 is concealed by the front wall 140 of the first door frame 100. The second hinge body 220 includes an L-shaped connecting frame 221 and a mounting block 222. The L-shaped connecting frame 221 includes a first connecting edge 223 and a second connecting edge 224 that are perpendicular to each other. A bushing 225 is formed at the end of the second connecting edge 224 away from the first connecting edge 223. The mounting block 222 is connected to the end of the second connecting edge 224 away from the first connecting edge 223. The mounting block 222 has a mounting surface 226 for connecting with the door body. The mounting surface 226 is perpendicular to the first connecting edge 223 and faces the side where the bushing 225 is located. The bushing 225 is embedded in the hinge notch 211. The second hinge body 220 is rotatably connected to the first hinge body 210 by passing through the hinge notch 211 and the bushing 225 via the pivot 230. The second hinge body 220 can rotate 180° around the pivot 230 from the first position to the second position, so that the mounting block 222 can rotate from the rear of the first door frame 100 to the front of the first door frame 100. Specifically, when the second hinge body 220 is in the first position, the mounting block 222 is located to the left rear of the pivot 230, and the mounting surface 226 faces to the right, so that after the mounting surface 226 is connected to the door body, the door body is set along the left and right. When the second hinge body 220 is in the second position, the mounting block 222 is located to the right front of the pivot 230.

[0035] The door body connected to the mounting surface 226 is a movable door 400. When the second hinge body 220 is in the first position, the movable door 400 is in the closed state, and the movable door 400 is located behind the first door frame 100. When the second hinge body 220 is in the second position, the movable door 400 is in the fully open state, and the movable door 400 passes around the first door frame 100 and reaches the front of the first door frame 100.

[0036] In some embodiments of this utility model, such as Figure 4As shown, it also includes a second door frame 300. The second door frame 300 is provided with a second accommodating cavity 310 for installing the mounting block 222 and a first mounting groove 320 for installing the door body. The mounting block 222 is embedded in the second accommodating cavity 310. The mounting surface 226 is provided with screw mounting holes 227. The mounting block 222 is connected to the second door frame 300 by screws. The groove direction of the first mounting groove 320 is the same as the orientation of the mounting surface 226. The shortest distance L1 from the axis of the rotating shaft 230 to the second door frame 300 is greater than the distance L2 from the axis of the rotating shaft 230 to the front wall 140 of the first door frame 100. The second hinge body 220 can rotate 180° around the rotating shaft 230 from the first position to the second position, so that the second door frame 300 can rotate from the rear of the first door frame 100 to the front of the first door frame 100. L1 > L2 ensures that when the movable door 400 rotates to the front of the first door frame 100, the second door frame 300 can smoothly pass around the first door frame 100 without being blocked or collided with it.

[0037] In some embodiments of this utility model, the concealed hinge 200 further includes two wear-resistant pads 240. The two wear-resistant pads 240 are sleeved on the pivot 230 and are located at the upper and lower ends of the bushing 225, respectively, sandwiched between the bushing 225 and the first hinge body 210. The wear-resistant pads 240 can reduce the noise generated by the relative rotation of the first hinge body 210 and the second hinge body 220 when the door is opened and closed.

[0038] In some embodiments of this utility model, the first hinge body 210 includes a main body 213 and two mounting plate parts 212. A hinge notch 211 is provided in the main body 213, and the two mounting plate parts 212 are respectively provided at the upper and lower ends of the main body 213. The main body 213 is fitted into the first receiving cavity 130. The mounting plate parts 212 are tightly attached to the rear wall 110 or right wall 120 of the first door frame 100. The mounting plate parts 212 are mounted on the rear wall 110 or right wall 120 of the first door frame 100 by screws. The fixing method of the mounting plate parts 212 can vary depending on the size of the first door frame 100. The mounting plate parts 212 are thin plate structures. When the side of the first profile is narrow, the mounting plate parts 212 can be fixed to the surface of the rear wall 110 of the first profile, such as... Figure 9 As shown.

[0039] In some embodiments of this utility model, the rear wall 110 or right wall 120 of the first door frame 100 is partially recessed inward to form a groove that matches the mounting plate portion 212, and the mounting plate portion 212 is embedded in the groove. When the side of the first profile is relatively wide, the mounting plate portion 212 can be embedded in the groove of the rear wall 110 or right wall 120 of the first door frame 100, so that the mounting plate portion 212 is flush with the surface of the first door frame 100, without occupying extra space. From the front, only the front wall 140 of the first door frame 100 is visible, resulting in a simple and beautiful appearance. Figure 10-11As shown.

[0040] In some embodiments of this utility model, the first door frame 100 has an L-shaped cross-section and is composed of a first frame body 150 and a second frame body 160 that are perpendicular to each other. The first frame body 150 and the second frame body 160 are an integral structure. The second frame body 160 is located on the left side of the rear side of the first frame body 150.

The second door frame 300 is located behind the first frame body 150 and to the right of the second frame body 160. The second mounting groove 161 is used to mount and fix the door 500. Further, as... Figure 7 As shown, the distance L3 from the right wall 120 of the first frame 150 to the second frame 160 is greater than the width L4 of the second door frame 300 in the left-right direction, and the length L5 of the second frame 160 in the front-back direction is greater than the length L6 of the second door frame 300 in the front-back direction. From the front, the second door frame 300 is completely hidden within the first door frame 100, with only the first door frame 100 visible, thus meeting the user's minimalist design requirements for the shower enclosure. Furthermore, the second frame 160 can cover the gap between the movable door 400 and the first door frame 100, preventing water from flowing outside the shower enclosure.

[0041] In some embodiments of this utility model, the hidden hinge 200 further includes a first positioning member 250, which is installed on the side wall of the hinge notch 211. When the second hinge body 220 is in the first position, the mounting block 222 is located to the left rear of the pivot 230, and the second connecting edge 224 abuts against the first positioning member 250. When the movable door 400 is closed, the first positioning member 250 abuts against the second connecting edge 224, preventing the movable door 400 from continuing to rotate inward and preventing the second door frame 300 from colliding with the first door frame 100.

[0042] In some embodiments of this utility model, an avoidance chamfer 228 is provided on the L-shaped connecting frame 221 at the corner where the first connecting edge 223 and the second connecting edge 224 meet, in order to prevent the second hinge body 220 from being blocked by the first positioning member 250 when rotating to the second position.

[0043] In some embodiments of this utility model, the hidden hinge 200 further includes a second positioning member 260, which is installed on the second connecting edge 224. When the second hinge body 220 is in the second position, the second positioning member 260 abuts against the first door frame 100. When the movable door 400 is opened 180°, the second positioning member 260 abuts against the right side of the first door frame 100, preventing the movable door 400 from continuing to rotate. After the movable door 400 is opened 180°, it is parallel to the fixed door 500, preventing the movable door 400 from colliding with the fixed door 500.

[0044] A shower enclosure includes the aforementioned door frame structure with concealed hinge 200. During installation, refer to... Figure 8 First, fix the assembled hidden hinge 200 to the second door frame 300, that is, connect the mounting surface 226 to the second door frame 300. Then, install the movable glass on the second door frame 300, rotate the hidden hinge 200 or the second door frame 300 by 90°, and then fix the first hinge body 210 to the first door frame 100.

[0045] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
