DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to FIGS. 1 to 4, a clamping-sliding assembly 30 for a single-track-suspension sliding door in accordance with the present invention is mounted between a track 10 and a glass door 50 to prevent the glass door 50 from turning over the track 10 and to adjust a height of the glass door 50 relative to the track 10. The track 10 may be L-shaped in cross section, is mounted securely on a wall and has an inner side, an inner top surface, a bottom, an opening 11 and a sliding recess 12. The opening 11 is formed through the inner side of the track 10. The sliding recess 12 is formed in the bottom of the track 10, communicates with the opening 11 and has a bottom face and a depth (D). In addition, a distance between the inner top surface of the track 10 and the bottom surface of the sliding recess 12 is defined as a first height (H).
The clamping-sliding assembly 30 is movably mounted in the sliding recess 12 of the track 10, is clamped on the glass door 50 and has a body 31 and a roller mount 33.
The body 31 may be rectangular U-shaped in cross section and has a bottom, a top, an inner side, a middle, a clamping recess 311, two inner mats 312, a connecting recess 313, at least one holding hole 318, at least one limiting pin 314, a connecting mount 315 and an adjusting bolt 316. The clamping recess 311 is transversally formed through the bottom of the body 31 and is used to clamp on a top of the glass door 50. The inner mats 312 are mounted in the clamping recess 311 and abut the sides of the glass door 50. The connecting recess 313 is longitudinally formed through the top and the inner side of the body 31 at the middle of the body 31 beside the clamping recess 311, communicates with the clamping recess 311 and has an inner opening formed through the inner side of the body 31 as shown in FIG. 2.
The at least one holding hole 318 is transversally formed in the body 31 at the connecting recess 313. The at least one limiting pin 314 is mounted securely in the at least one holding hole 318 at the connecting recess 313 near the top of the body 31. The connecting mount 315 may be rectangular, is formed on and protrudes in the connecting recess 313 at the top of the body 31 to extend inwardly to the inner opening of the connecting recess 313 and has an adjusting hole 317 longitudinally formed through the connecting mount 315 and communicating with the connecting recess 313. Additionally, the connecting mount 315 is formed on and protrudes in the connecting recess 313 at a middle of the connecting recess 313 to form two upper openings at the top of the body 31 beside the connecting mount 315. The adjusting bolt 316 is rotatably connected to the connecting mount 315 in the adjusting hole 317 and has a top end, a bottom end and a length. The top end of the adjusting bolt 316 extends out of the connecting mount 315 above the top of the body 31. The bottom end of the adjusting bolt 316 extends out of the connecting mount 315 and extends in the connecting recess 313. The length of the adjusting bolt 316 is defined as a second height (B).
The roller mount 33 is movably mounted in the connecting recess 313 of the body 31 at the inner side, abuts the adjusting bolt 316 and has a top, a bottom, a middle, an inner side, an outer side, at least one roller 331, an abutting face 332 and at least one elongated hole 333. The outer side of the roller mount 33 faces the track 10. The at least one roller 331 is rotatably connected to the outer side of the roller mount 33 near the bottom of the roller mount 33 to extend out of the inner side of the body 31 via the inner opening of the connecting recess 313, is rotatably mounted in the sliding recess 12 of the track 10 and each one of the at least one roller 331 has a bottom face. Preferably, the roller mount 33 has two rollers 331 rotatably connected to the outer side of the roller mount 33 near the bottom of the roller mount 33 and rotatably mounted in the sliding recess 12 of the track 10.
The abutting face 332 is formed in the top of the roller mount 33 at the middle of the roller mount 33 and abuts the bottom end of the adjusting bolt 316. Furthermore, with reference to FIG. 2, the roller mount 33 has two guiding tabs 334 formed on and protruding upwardly from the top of the roller mount 33 beside the abutting face 332 and respectively mounted in the upper openings to prevent the roller mount 33 from tilting relative to the body 31. When adjusting bolt 316 is rotated to move relative to the body 31, the roller mount 33 is moved relative to the body 31 by the adjusting bolt 316 pushing against the abutting face 332 of the roller mount 33 and this can be used to adjust the height of the body 31 relative to the roller mount 33. Furthermore, a distance between the abutting face 332 and the bottom face of the at least one roller 331 is defined as a third height (A). The at least one elongated hole 333 is formed through the sides of the roller mount 33 near the top and is mounted around the at least one limiting pin 314 to prevent the roller mount 33 separating from the body 31 when the roller mount 33 is mounted in the sliding recess 12 of the track 10. Preferably, the at least one elongated hole 333 of the roller mount 33 is formed through one of the guiding tabs of the roller mount 33.
In addition, a distance between the top end of the adjusting bolt 316 and the inner top surface of the track 10 is defined as a movable height (d) and is a fixed value when the clamping-sliding assembly 30 is mounted between the glass door 50 and the track 10, and the movable height (d) is shorter than the depth (D) of the sliding recess 12. Furthermore, a distance between a highest point of the movable height (d) of the adjusting bolt 316 and the bottom face of the at least one roller 331 can be also defined as the first height (H), and a depth of the at least one roller 331 that is mounted in the sliding recess 12 is same as the depth (D) of the sliding recess 12.
With reference to FIG. 3, in order to avoid the adjusting blot 316 to interfere with the inner top surface of the track 10 during an assembling process, the height of the adjusting blot 316 (the second height B) is shorter than a distance that is formed by the first height (H) minus the third height (A) (that is B<H−A). Therefore, if the size of the track 10 is changed with different first height (H), the adjusting bolt 316 of the body 31 may be changed with a one with different second height (B) to prevent the adjusting blot 316 from interfering with the inner top surface of the track 10 during the assembling process.
Additionally, in order to prevent the clamping-sliding assembly 30 from turning over the track 10, the height of the adjusting bolt 316 (the second height B) is longer than a distance that is the first height (H) minus the third height (A) and the depth (D)(that is B>H−A−D). Then, a relationship equation between the heights and the depth of the clamping-sliding assembly 30 is defined as: H−A−D<B<H−A. Therefore, if the sizes of the components of the track 10 and the clamping-sliding assembly 30 are satisfied the above-mentioned relationship equation, the components of the clamping-sliding assembly 30 can be assembled in the track 10 to prevent the clamping-sliding assembly 30 from turning over the track 10.
When assembling the clamping-sliding assembly in accordance with the present invention on a single-track-suspension sliding door such as a glass door 50, with reference to FIG. 4, the track 10 is mounted securely on a wall and a top of the glass door 50 is moved to the opening 11 of the track 10. Because the sizes of the components of the track 10 and the clamping-sliding assembly 30 are satisfied the above-mentioned relationship equation (H−A−D<B<H−A) as shown in FIG. 3, the adjusting bolt 316 will not interfere with the inner top surface of the track 10 and the glass door 50 will not turn over the track 10 after the glass door 50 mounted with the clamping-sliding assembly 30.
Furthermore, with referenced to FIGS. 2 and 5A, when the glass door 50 is mounted on the track 10 via the clamping-sliding assembly 30, the height of the glass door 50 relative to the track 10 can be adjusted by rotating the adjusting bolt 316 to move upwardly relative to the body 31 and to press against the abutting face 332 of the roller mount 33. Because the roller mount 33 is mounted in the sliding recess 12 of the track 10 and cannot be moved relative to the track 10, the body 31 will be moved downwardly relative to the roller mount 33 by the connecting mount 315 moving downwardly relative to the adjusting bolt 316. Then, the glass door 50 that is connected securely to the body 31 will be moved downwardly relative to the track 10, and the height of the glass door 50 relative to the track 10 is adjusted.
In addition, with reference to FIG. 5B, when the adjusting bolt 316 is rotated in reverse relative to the adjusting bolt 316 in FIG. 5A, the adjusting bolt 316 is moved downwardly relative to the body 31 and to press against the abutting face 332 of the roller mount 33. Because the roller mount 33 is mounted in the sliding recess 12 of the track 10 and cannot be moved relative to the track 10, the body 31 will be moved upwardly relative to the roller mount 33 by the connecting mount 315 moving upwardly relative to the adjusting bolt 316. Then, the glass door 50 that is connected securely to the body 31 will be moved upwardly relative to the track 10, and the height of the glass door 50 relative to the track 10 is adjusted. Furthermore, during the operation of adjusting the height of the glass door 50 relative to the track 10 in FIGS. 5A and 5B, the movable height (d) is a fixe value without changing and this can prevent the adjusting bolt 316 from interfering with the inner top surface of the track 10 during the adjusting process.
According to the above-mentioned, the clamping-sliding assembly 30 for a single-track-suspension sliding door in accordance with the present invention, the sizes (the heights and the depth) of the track 10 and the clamping-sliding assembly 30 have been known in production. When the clamping-sliding assembly 30 is needed to assemble with a track having a different size, the user can change the adjusting bolt 316 with a different size according to the relationship equation (H−A−D<B<H−A). Therefore, the user can assemble the glass door 50 with the track 10 via the clamping-sliding assembly 30 according to the relationship equation to prevent the adjusting bolt 316 from interfering with the inner top surface of the track 10 during the assembling process and also can prevent the glass door 50 from turning over the track 10. Therefore, the clamping-sliding assembly 30 can be assembled between the track 10 and glass door 50 to avoid the adjusting bolt 316 to interfere with the track 10 and to prevent the sliding door 50 from turning over the track 10. Furthermore, the user also can adjust the height of the glass door 50 relative to the track 10 by rotating the adjusting bolt 316 relative to the connecting mount 315. Consequently, the adjusting bolt 316 of the body 31 in accordance with the present invention can be used to avoid to interfere with the track 10 and to prevent the sliding door 50 from turning over the track 10.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
