[0002] Shower room is a kind of bathroom facility that makes full use of bathroom space, which clearly divides the shower range in the bathroom through the door, thereby forming a relatively independent bathing space. Most of the existing shower rooms use sliding doors as their doors. The sliding door slides in the track to open and close the shower room.
[0003] Currently, the sliding door is usually equipped with a buffer to avoid collision during sliding. This type of sliding door usually has an additional slot in the inside of the track groove, which is used to install a buffer adjusting piece to trigger the buffer. However, the existing buffer adjusting piece usually needs to be installed and fixed by bolts. The buffer adjusting piece and the bolts are installed together in the slot, which occupies the original space of the track groove. This results in the need to increase the volume of the internal space of the track groove, which often leads to an increase in the height of the track, and thus the appearance of the track appears to be relatively wide, affecting the visual proportion between the track and the sliding door. Moreover, the sliding door usually only needs to be equipped with a buffer in one track. However, due to the large difference in the outer dimensions of the track with a slot and the track without a slot, the track without a slot needs to increase its outer dimensions to match the appearance, resulting in material waste.

[0046] Embodiment
[0047] Reference Figures 1-8 The utility model discloses a track piece 100, which comprises a track body 1, a track block 2 and an adjusting hole group 3. The track body 1 is provided with a guide groove 4, and the guide groove 4 has a slot 4a on a first side 5. The track block 2 is arranged in the guide groove 4 and along the length direction of the guide groove 4. The adjusting hole group 3 is arranged on the side wall of the guide groove 4 on a second side 6 opposite to the first side 5. The adjusting hole group 3 comprises a first adjusting hole 3a and a second adjusting hole 3b. The first adjusting hole 3a is communicated to the outside and extends towards the first side 5. The second adjusting hole 3b is on the first side 5 of the first adjusting hole 3a and is communicated with the first adjusting hole 3a, so that the side wall of the guide groove 4 on the second side 6 is through. The aperture of the second adjusting hole 3b is smaller than that of the first adjusting hole 3a.
[0048] It should be noted that the track piece 100 has a first direction X, a second direction Z and a third direction Y perpendicular to each other. The first direction X is defined as the length direction of the track piece 100, the second direction Z is defined as the height direction of the track piece 100, and the third direction Y is defined as the width direction of the track piece 100. The slot 4a of the guide groove 4 is usually located on the height direction of the track piece 100, i.e. the second direction Z, so the first side 5 and the second side 6 are two opposite sides in the second direction Z.
[0049] This track component 100 is typically used as a guide rail. Depending on the specific application, the track component 100 can be equipped with or without a buffer 10. When the buffer 10 is installed, the track component 100 can utilize the adjustment hole group 3 on the side wall of its second side 6 to house the bolts and nuts required for installing the buffer 10. This eliminates the need to increase the space occupied by the track component 100, which helps control its volume and effectively limits the surface area of the track component 100, resulting in higher space utilization.
[0050] It is understandable that the diameter of the second adjusting hole 3b is smaller than that of the first adjusting hole 3a, and the second adjusting hole 3b is connected to the first adjusting hole 3a. This will cause the adjusting hole group 3 to form a countersunk hole, countersunk hole, or other hole structure. Furthermore, this hole structure is a through hole, which allows the guide groove 4 to penetrate the side wall of the second side 6. In this way, the first adjusting hole 3a can be used to store nuts, screws, and other accessories. When the buffer 10 needs to be installed on the track component 100, the nuts, screws, and other accessories can enter the guide groove 4 through the adjusting hole group 3, and the accessories will not protrude from the outer edge of the track component 100, so as not to affect the normal installation and use of the track component 100. Moreover, by using the first adjusting hole 3a to store nuts, screws, and other accessories, the shape of the track component 100 can be more coordinated and easier to install.
[0051] It should be noted that the track block 2, as the guide structure of the track component 100, can be set at the slot 4a, or inside the guide groove 4. Alternatively, it can be set on one side of the guide groove 4 in the third direction Y, or on both sides of the guide groove 4 in the third direction Y. As long as the track block 2 can meet the sliding requirements of the door body 9 matched with the track component 100, it will not be elaborated here.
[0052] When the track block 2 is located on the side of the guide groove 4, if the door body 9 only cooperates with one track block 2, there is a certain risk of the door body 9 derailing during sliding. Therefore, in addition to the track block 2, this track component 100 can be configured with other guide structures to prevent the wheels from disengaging from the track block 2 when the door body 9 slides relative to the track component 100. For example, refer to... Figures 1-2 As an example of this embodiment, the guide groove 4 is provided with a guide block 7 extending toward the groove opening 4a on the side wall of the second side 6, and the guide block 7 is arranged along the length direction of the guide groove 4.
[0053] The guide block 7 is typically located in the middle of the guide groove 4 to cooperate with the track block 2 located on the side of the guide groove 4, thereby constraining the door body 9 to move along the track block 2. It should be noted that a cavity can be provided inside the guide block 7 to reduce the overall weight of the track component 100. Moreover, by providing the guide block 7, the structural thickness of the guide groove 4 of the track component 100 is increased, thereby giving the track component 100 higher structural strength.
[0054] Multiple adjustment hole groups 3 can be configured within the track component 100, which facilitates flexible selection of the installation position of accessories when installing them within the track component 100. (Reference) Figures 1-3 When there are multiple adjustment hole groups 3, they are usually arranged at intervals along the length of the guide groove 4. Furthermore, when a guide block 7 is provided within the guide groove 4, the multiple adjustment hole groups 3 are also arranged at intervals relative to the guide block 7. Of course, these two arrangements are not required to be implemented simultaneously. The track component 100 can select one arrangement method or use both arrangements simultaneously according to the installation requirements of the accessories.
[0055] It is important to note that after the accessories are installed on the track component 100, the nuts, screw heads, and other accessories will be concealed within the first adjustment hole 3a, exposed to the external environment. This poses a certain risk of damage to the nuts, screw heads, and other accessories, such as water corrosion. Furthermore, the direct exposure of the nuts, screw heads, and other accessories to the external environment will also affect the appearance of the track component 100. Therefore, the track component 100 can be equipped with an outer cover 8. The outer cover 8 wraps around the outside of the track body 1, providing protection for the track body 1 while concealing the nuts, screw heads, and other accessories, preventing them from being directly exposed to the external environment. Of course, the outer cover 8 must keep the opening 4a of the guide groove 4 exposed to avoid obstructing the entry and exit of the door 9 into and out of the track component 100.
[0056] Using the aforementioned track component 100, this embodiment also provides a door assembly 200, which includes a door body 9, the aforementioned track component 100, a buffer 10, a traveling wheel 11, and a locking component 12. The track component 100 is disposed on one side of the door body 9 in the height direction; the buffer 10 is disposed on the second side 6 of the guide groove 4; the traveling wheel 11 is rotatably connected to the door body 9 and travels on the track block 2; and the traveling wheel 11 can cooperate with the buffer 10 to trigger the buffer 10.
[0057] It should be noted that in this embodiment, the door assembly 200 is oriented according to the first direction X, the second direction Z, and the third direction Y of the track member 100. Specifically, the first direction X of the track member 100 is defined as the left-right direction of the door assembly 200, and the left and right sides are distinguished by the direction the user faces when outside the shower room. The second direction Z of the track member 100 is defined as the up-down direction of the door assembly 200, and the up and down sides are distinguished by the upper and lower sides of the door assembly 200 during normal use. The third direction Y of the track member 100 is defined as the front-back direction of the door assembly 200, and the side of the door assembly 200 facing the user when outside the shower room is the front side, and the opposite side is the rear side.
[0058] By utilizing the adjusting hole group 3 formed in the side wall of the second side 6 of the track member 100, the locking member 12 can form various mating methods with the track member 100. For example, refer to... Figure 6 When the buffer 10 has a countersunk hole or other hole structure, the locking member 12, i.e., the bolt, can pass through the buffer 10 and extend into the adjusting hole group 3, where it is connected and fixed to the fastener 13, i.e., the nut, located in the second adjusting hole 3b. When the buffer 10 has a threaded hole or a fastener 13 is disposed within the buffer 10, the locking member 12 can also be arranged in the first adjusting hole 3a, pass through the second adjusting hole 3b, extend into the buffer 10, and be connected and fixed to the buffer 10. Further details are not provided in the accompanying drawings.
[0059] Based on the cooperation between the locking member 12 and the track member 100, the door assembly 200 can utilize the space of the side wall of the second side 6 of the track member 100 to hide the buffer 10 inside the guide groove 4, and hide the locking member 12 used to install the buffer 10 inside the adjustment hole group 3. In this way, the door assembly 200 with the buffer 10 installed does not need to expand the space occupied by the guide groove 4, thereby controlling the visual proportion between the track member 100 and the door 9 within a reasonable range.
[0060] It should be noted that when the track component 100 is equipped with a buffer 10, the locking component 12 and fastener 13 can be hidden using the adjustment hole group 3 without increasing the space occupied by the track component 100. Therefore, the track component 100 can be designed according to the specifications without the buffer 10, so that the height of the track component 100 can be compressed to 45mm. Moreover, the track component 100 can install the buffer 10 with the same specifications and dimensions, so that the track component 100 can meet the two requirements of the door body 9 with and without the buffer 10 with the same specifications and dimensions, thus having a wider range of applications.
[0061] The location of the buffer 10 installed on the door assembly 200 may vary in different application scenarios. For easier adjustment of the buffer 10's position within the guide groove 4, please refer to... Figure 1 , 6 As an example of this embodiment, the adjustment hole group 3 extends along the length direction of the guide groove 4, i.e., the first direction X. In this way, the buffer 10 can adjust its position in the guide groove 4 according to the length of the adjustment hole group 3 in the first direction X. Especially when multiple buffers 10 are provided in the guide groove 4, this is beneficial for multiple buffers 10 to be installed at intervals so that multiple buffers 10 can cooperate with each other. Moreover, the buffer 10 can adjust its position in the guide groove 4 by using the adjustment hole group 3, which is also beneficial for buffers 10 of different specifications to cooperate with each other in the same guide groove 4.
[0062] During the adjustment of the position of the buffer 10 within the guide groove 4, a guide structure can be configured within the track member 100 to guide the adjustment direction of the buffer 10 and prevent it from deviating from the movement path of the traveling wheel 11. For example, when the buffer 10 is fixed using the locking member 12 and the fastener 13, this guide structure can be formed by the interaction between the adjusting hole group 3 and the fastener 13. (Reference) Figure 7 As an example of this embodiment, the fastener 13 has a first side surface 13a arranged along the length direction of the first adjustment hole 3a. The first side surface 13a fits against the side wall of the first adjustment hole 3a and cooperates with the first adjustment hole 3a to restrict the rotation of the fastener 13 relative to the first adjustment hole 3a. When the buffer 10 is locked by the locking member 12 and the fastener 13, the fastener 13 is constrained by the first adjustment hole 3a and can only move along the length direction of the first adjustment hole 3a. This also means that the buffer 10 can only move along the length direction of the first adjustment hole 3a. Since the length direction of the first adjustment hole 3a is the same as the length direction of the guide groove 4, the movement of the buffer 10 along the length direction of the first adjustment hole 3a ensures that the buffer 10 will not deviate from the movement path of the traveling wheel 11.
[0063] It should be noted that when the buffer 10 moves relative to the guide groove 4, the fastener 13 arranged in the first adjustment hole 3a may rub against the track component 100, which can easily lead to wear of the fastener 13 and the first adjustment hole 3a. Therefore, referring to Figure 8 In some door components 200, when the locking member 12 is connected and fixed to the fastener 13, a protective block 14 may be fitted on the outer periphery of the fastener 13. The protective block 14 may be made of a wear-resistant material.
[0064] Of course, when the fastener 13 is equipped with a protective block 14, the fastener 13 and the first adjusting hole 3a cannot form a guiding structure to guide the movement direction of the buffer 10. Therefore, referring to Figure 8As an example of this embodiment, the protective block 14 may have a second side surface 14a arranged along the length direction of the first adjustment hole 3a. The second side surface 14a fits against the side wall of the first adjustment hole 3a and cooperates with the first adjustment hole 3a to restrict the rotation of the protective block 14 relative to the first adjustment hole 3a. In this way, the protective block 14 can cooperate with the first adjustment hole 3a to form a guide structure adapted to the buffer 10.
[0065] refer to Figure 6 As an example of this embodiment, when a guide block 7 is provided inside the track component 100, a guide block 15 can be provided on the door body 9. The guide block 15 travels on the side of the guide block 7 facing the slot 4a, thereby cooperating with the traveling wheel 11 to limit the door body 9 on both sides in the third direction Y, preventing the door body 9 from falling off. Of course, in order to ensure that the guide block 15 can travel smoothly on the guide block 7, the side of the guide block 7 facing the slot 4a is usually a plane.
[0066] In summary, the present invention provides a track component 100 and a door assembly 200. The track component 100, by providing an adjustment hole group 3 on the side wall of the guide groove 4 on the second side 6, allows the locking component 12 to be stored in the side wall space of the track body 1 when the accessories are installed inside the guide groove 4. In this way, the track component 100 does not need to occupy additional space, which is beneficial to controlling the volume of the track component 100. Moreover, the area of the outer surface of the track component 100 can be effectively controlled, resulting in higher space utilization and more material savings.
[0067] Furthermore, the door assembly 200 with this track component 100 can hide the buffer 10 inside the guide groove 4 and conceal the locking component 12 used to install the buffer 10 inside the adjustment hole group 3. This eliminates the need for the door assembly 200 to expand the space occupied by the guide groove 4 when the buffer 10 needs to be installed, thereby controlling the visual proportion between the track component 100 and the door 9 within a reasonable range. Moreover, since the track component 100 occupies little space, installing the buffer 10 on the track component 100 will not additionally expand the space occupied by the guide groove 4. This allows the track component 100 to simultaneously meet the two requirements of the door 9 being equipped with or without the buffer 10, thus broadening its application range.
[0068] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
