slide rail mechanism

Abstract

A slide rail mechanism includes a fixed rail unit, a movable rail unit slidably mounted on the fixed rail unit, and a tail hook protruding from a top side of the movable rail unit. The movable rail unit is spaced apart beside a fixed wall of the fixed rail unit. The tail hook has an upper protruding portion protruding upward from the movable rail unit, and a plug-in portion bent and protruding forward from the upper protruding portion. The plug-in portion has a sharp protruding segment with a left and right width gradually narrowing forward, and protruding obliquely away from the fixed wall. The structure design of the sharp protruding segment protruding obliquely away from the fixed wall enables the slide rail mechanism to have an adjustable space between the drawer and the movable rail unit when the slide rail mechanism is installed on a drawer cabinet. The shortcomings of the existing slide rail mechanism for the drawer cabinet are completely improved.

Description

Technical Field

[0001] This invention relates to a slide mechanism, and more particularly to a slide mechanism for a drawer cabinet. Background Technology

[0002] See Figures 1-5 Drawer slides, used in furniture, come in various types. A typical drawer slide mechanism 100 for cabinets generally includes a fixed rail 101 fixed to the side wall 201 of the cabinet body 20, and a movable rail 103 that slides back and forth on the fixed rail 101 and supports the drawer 202. The fixed rail 101 has a spaced, upright extension on either side of the movable rail 103, and a fixed wall 102 for fixing to the side wall 201. The rear end of the movable rail 103 has an L-shaped hook 104 that protrudes upwards behind the drawer 202 and bends forward, extending straight forward. The hook 104 has a forward-pointing tip located at the center of its width.

[0003] During the assembly of the drawer cabinet, the fixed rails 101 of the two slide rail mechanisms 100 are respectively installed on the left and right side walls 201 of the cabinet body 20, and the drawer 202 is straddled on the movable rail 103, so that the left and right upright side panels 203 of the drawer 202 face each other and abut against the left and right opposite sides of the movable rail 103, and the tail hooks 104 are respectively inserted forward into the two alignment holes 204 on the rear side of the drawer 202. That is, the inner lower edge of the left and right upright side panels 203 of the drawer 202 forms a shielding surface 205 that abuts against the movable rail 103, and the outer side of the movable rail 103 has a hidden wall 105 that abuts against the shielding surface 205. In this way, when the drawer 202 is pulled out and unfolded, the shielding surface 205 covers the hidden walls 105 of the two movable rails 103 in contact, forming a design in which the movable rails 103 are hidden to achieve the overall aesthetics.

[0004] In order to allow the tail hook 104 to be aligned and inserted into the alignment hole 204 of the drawer 202, after the slide rail mechanism 100 is fixed to the cabinet body 20, the drawer 202 is first stacked against the movable rail 103, and then the movable rail 103 is moved forward relative to the drawer 202. The tip of the tail hook 104 strikes out two impact points 209 on the rear side of the drawer 202. Then, the alignment hole 204 is drilled forward with a drill bit 200 of the diameter corresponding to the width of the tail hook 104, aligned with the impact points 209.

[0005] Following the minimalist design trend, the front doors 208 of drawers 202 are now mostly handle-less, relying on spring tension for opening and closing. However, the self-opening slide rails suffer from instability during opening and require a certain gap between the front door 208 and the front panel of the cabinet 20 for triggering. This gap is prone to allowing foreign objects to seep in. Furthermore, the upper edge of the handle-less drawer 202's front door 208 is beveled to allow users to pull the drawer out with their fingertips. This not only results in a small contact area but also makes it more difficult to apply force. While achieving the aesthetic appeal of a handle-less minimalist design, this inconveniences the user.

[0006] For many years, the assembly method used in the market has been in place. However, the width of the slide rail mechanism 100 corresponding to the cabinet body 20 and drawer 202 has been subject to too many unpredictable errors in achieving the optimal manufacturing dimensions and the diagonal of the assembled panels. This results in inaccuracies in the width of the assembled drawer 202 or inconsistencies in its front and rear widths. Consequently, when the drawer 202 is mounted on the slide rail mechanism 100, the front door panel 208 of the drawer 202 in the closed state will... Figure 5 and Figure 15 , 16 The front panel 208 is slightly tilted relative to the front side of the cabinet 20, causing one side of the front door panel 208 to fit completely against the front side of the cabinet 20, while the other side cannot fit completely against the front side of the cabinet 20, forming a gap 207. This results in a difference in the horizontal plane between adjacent upper and lower, and left and right sides. The existing solution on the market is to increase the Newtonian force of the spring (not shown) to forcefully close the gap 207, which further increases the difficulty for the user to pull out the drawer 202, making it extremely difficult to open. This solution inevitably solves one problem but exacerbates another. That is, increasing the spring force to improve the incomplete closure problem causes difficulty in opening; conversely, reducing the spring force to make the drawer 202 open smoothly causes the problem of not being able to close properly. The two problems are contradictory.

[0007] In addition, see Figure 1 , Figure 3 and Figure 4 Because the hidden wall 105 of the movable rail 103 of the slide rail mechanism 100 is respectively limited and abutted against the shielding surface 205 of the left and right side panels 203 of the drawer 202, it is impossible to make the drawer 202 open and close smoothly by adjusting relative to the slide rail mechanism 100, or to make the front door panel 208 of the drawer 202 (shown in) Figure 5The fixed rail 101 is completely pressed against the cabinet body 20. This causes the double-sided slide rail mechanism 100 to be subjected to parallel compression and V-shaped movement. Therefore, it is extremely difficult to improve the two existing problems with a single structure. However, it is necessary to improve it. When the fixed rail 101 is locked to the side wall 201 of the cabinet body 20 and is in an immovable state, the hidden wall 105 of the double-sided movable rail 103 is sandwiched by the shielding surfaces 205 on both sides of the drawer 202 in contact with each other. This also causes the double-sided movable rail 103 to be forcibly squeezed and stretched by the shielding surfaces 205 on both sides with unpredictable tolerances, and it cannot slide smoothly with the fixed rail 101. Summary of the Invention

[0008] The purpose of this invention is to provide a slide rail mechanism that can improve upon at least one of the disadvantages of prior art.

[0009] The slide rail mechanism of the present invention includes a fixed rail unit, a movable rail unit slidably mounted on the fixed rail unit, and a tail hook protruding from the top side of the rear end of the movable rail unit. The fixed rail unit has a fixed wall. The movable rail unit is spaced apart from the fixed wall. The tail hook has an upper protrusion extending upward from the movable rail unit and an insertion portion extending forward from the upper protrusion. The insertion portion has a pointed protrusion that gradually narrows forward from a maximum left-right width. The pointed protrusion is divided into two sides by a left-right width center line. The side of the pointed protrusion away from the fixed wall protrudes away from the left-right width center line and has an impact point.

[0010] In the slide rail mechanism of the present invention, the pointed protrusion of the tail hook has a long straight inclined side extending from back to front, and a short straight inclined side extending from back to front and connected to the front end of the long straight inclined side and having a length shorter than the length of the long straight inclined side, wherein the long straight inclined side is located between the short straight inclined side and the fixed wall.

[0011] In the slide rail mechanism of the present invention, the left and right tilt angles of the long straight inclined side and the short straight inclined side are different.

[0012] The beneficial effect of this invention is that, through the structural design of the pointed protrusion of the tail hook extending obliquely away from the fixed wall, when the slide rail mechanism of this invention is installed in a drawer cabinet, a slight adjustment space can be reserved between the two concealed surfaces on both sides of the drawer and the two hidden walls of the movable rail unit on both sides. This completely improves the shortcomings of existing slide rail mechanisms for drawer cabinets. Attached Figure Description

[0042] See Figure 6 , 7 8. One embodiment of the slide rail mechanism 300 of the present invention is suitable for installation in pairs between a cabinet body 800 and a drawer 900 in a drawer cabinet, allowing the drawer 900 to be pushed and pulled back and forth relative to the cabinet body 800. The cabinet body 800 has two vertically spaced side walls 801. The drawer 900 has a first side panel 901 and a second side panel 902 extending back and forth and spaced left and right, and a front panel 904 (shown in...) spanning the front ends of the first side panel 901 and the second side panel 902. Figure 13 The front panel 904 includes a rear side plate 903 spanning the rear ends of the first side plate 901 and the second side plate 902, and a bottom plate 906 disposed between the bottom of the first side plate 901, the second side plate 902, the rear side plate 903, and the front panel 904. The first side plate 901 and the second side plate 902 protrude downwards over the bottom edge of the bottom plate 906 and the rear side plate 903. The rear side plate 903 has two left-right spaced alignment holes 905 drilled on its rear side (shown in...). Figure 12 The first side plate 901 and the second side plate 902 each have a shielding surface 907 on the inner side of their bottom edges.

[0043] Since the two slide rail mechanisms 300 used for mounting on the left and right sides of the drawer 900 are mirror-symmetrical, for ease of explanation, in the following embodiments, they are mounted on... Figure 7 The structure of the drawer 900 is described using the right-side side wall 801 of the cabinet 800 and the slide rail mechanism 300 installed on the right side of the drawer 900 as an example.

[0044] The slide rail mechanism 300 includes a fixed rail unit 31 extending back and forth, a movable rail unit 32 that can be slidably mounted on the fixed rail unit 31, a tail hook 33 protruding from the top side of the rear end of the movable rail unit 32, and an assembly hole 34 provided on the front side of the movable rail unit 32.

[0045] The fixed rail unit 31 has a fixed rail body 311 extending forward and backward, and a fixed wall 312 vertically connected to the right side of the fixed rail body 311 and used for fixing to the corresponding side wall 801. The movable rail unit 32 is slidably mounted on the fixed rail body 311, and is spaced to the left of the fixed wall 312, which cooperates with the fixed rail unit 31 to define an upper-facing embedding space 30 between the two opposing sides.

[0046] The movable rail unit 32 has a hidden wall 321 adjacent to the shielding surface 907 of the drawer 900. Since there are many structural designs for the movable rail unit 32 to slide back and forth relative to the fixed rail body 311, and the assembly hole 34 is also prior art, the above-mentioned structure is not the focus of the improvement of the present invention, so it will not be described in detail, and the implementation is not limited to the form shown in the drawings.

[0047] The tail hook 33 has an upper protrusion 331 extending upward from the top surface of the movable rail unit 32, and an insert portion 332 that bends forward from the top of the upper protrusion 331. The insert portion 332 has a pointed protrusion 334 whose width gradually decreases forward from left to right. In this embodiment, the maximum left and right width of the insert portion 332 is D.

[0048] See Figure 6 , Figure 8 and Figure 9 The following description uses the slide rail mechanism 300 on the right side of the diagram as an example. The forward impact point 335 of the pointed protrusion 334 is offset to the left of the left side of the left-right width center line 700. The offset distance between the impact point 335 and the left-right width center line 700 is W, and the offset distance W is less than or equal to half of the maximum left-right width D of the pointed protrusion 334. The pointed protrusion 334 has a long straight inclined side 336 located on the right side and extending obliquely to the left from back to front across the left-right width center line 700, and a short straight inclined side 337 located on the left side and obliquely approaching the left-right width center line 700 from back to front and connected to the front end of the long straight inclined side 336. The length of the long straight inclined side 336 is greater than the length of the short straight inclined side 337, and the left-right oblique angles of the long straight inclined side 336 and the short straight inclined side 337 are different. The long straight inclined side 336 is located between the short straight inclined side 337 and the fixed wall 312. The shape of the slide rail mechanism 300 on the left is exactly the opposite of the shape described above, and will not be explained further below.

[0049] When the slide rail mechanism 300 of the present invention is used to be installed in pairs on the drawer 900 and the cabinet 800 to manufacture a drawer cabinet, the slide rail mechanism 300 with an appropriate width is selected based on the spacing dimensions of the side walls 801 of the cabinet 800 and the spacing dimensions of the first side panel 901 and the second side panel 902 of the drawer 900. The fixed wall 312 of the slide rail mechanism 300 is fixed to the left and right side walls 801 of the cabinet 800, respectively. The first side panel 901 and the second side panel 902 of the drawer 900 are inserted downwards into the mounting space 30 of the slide rail mechanism 300, and can be moved left and right across the movable rail unit 32 of the slide rail mechanism 300. This allows the hidden wall 321 of the movable rail unit 32 to be separated from the shielding surface 907 of the adjacent first side panel 901 and the shielding surface 907 of the second side panel 902 by an adjustable space 39 with a width of W (shown in the figure). Figure 7 ).

[0050] See Figure 8 , 9 10. After the slide rail mechanism 300 has been fixed to the cabinet body 800, the drawer 900 is placed across the movable rail unit 32, in front of the tail hook 33. Then, the tail hook 33 can be used to mark the drilling position of the rear side panel 903 of the drawer 900.

[0051] This embodiment takes drilling and positioning on the right side of the rear panel 903 of the drawer 900 as an example. First, the drawer 900 is moved to the left by a distance of width W relative to the right side slide rail mechanism 300, so that the hidden wall 321 of the movable rail unit 32 is relatively limited to the right and abuts against the shielding surface 907 of the second side panel 902 of the drawer 900. Next, the movable rail unit 32 is pushed forward relative to the drawer 900, thereby driving the tail hook 33 to strike the rear panel 903 of the drawer 900 with its impact tip 335, leaving an impact dent 909 on the rear panel 903. The impact dent 909 is the positioning mark for the drilling position on the right side of the rear panel 903.

[0052] See Figure 7 , 10 Similarly, the drawer 900 is moved to the right by a distance of width W relative to the left side slide rail mechanism 300, so that the hidden wall 321 of the left side movable rail unit 32 is limited to the left and abuts against the shielding surface 907 of the first side panel 901 of the drawer 900, and the movable rail unit 32 moves forward relative to the drawer 900, and the tail hook 33 strikes the drawer 900 forward to produce an impact dent 909, thus completing the positioning mark of the left side hole position of the rear side panel 903.

[0053] See Figure 10 ,12 Then, you can drill (as shown) Figure 25 Drill holes forward to align with the positioning marks, and drill alignment holes 905 on the rear side of the rear panel 903. Finally, push the drawer 900 backward relative to the movable rail unit 32, so that the tail hooks 33 of the slide rail mechanism 300 are inserted forward into the alignment holes 905 respectively, so that each tail hook 33 is inserted into the corresponding alignment hole 905, thus completing the assembly of the rear side of the drawer 900 with the slide rail mechanism 300. The assembly process can also be found in [reference needed]. Figures 21-22 (Similar to the assembly process involved in the background art, i.e.) Figures 19-20 And its assembly method can also be as follows: Figures 23-25 As shown, when the slide rail mechanism 300 is not yet installed on the cabinet 800, the drawer 900 is inverted so that the slide rail mechanism 300 is engaged to position the alignment hole 905. Therefore, the implementation is not limited to the above assembly method.

[0054] See Figure 6 , 13 26, 27, 28. During the assembly and manufacturing of this drawer cabinet, an adjustment mechanism 908 will be installed between the front end of the movable rail unit 32 and the drawer 900. This adjustment mechanism 908 is assembled to the bottom surface of the drawer 900 and its locking position can be adjusted. The adjustment mechanism 908 is also fastened to the assembly hole 34 to position the drawer 900 relative to the front end of the movable rail unit 32. Since the structure of the adjustment mechanism 908, which is fixed to the bottom surface of the drawer 900 and can be adjusted left and right, is not the focus of this work, it will not be described in detail.

[0055] See Figure 8 , 10 12, 14, 17, 18. This technology utilizes the characteristic that the forward-facing impact point 335 of the pointed protrusion 334 deviates from the left-right width centerline 700 by a distance W, causing the alignment hole 905 to also shift a distance W towards the center of the drawer 900. That is, when the hidden wall 321 abuts against the second side panel 902, there will be a deviation distance F between the edge of the tail hook 33 and the alignment hole 905 (visible in…). Figure 21This causes the tail hook 33 to extend into the alignment hole 905 when the drawer 900 is subsequently installed on the slide rail mechanism 300. This creates an adjustable space 39 with a distance of W between the hidden wall 321 of each movable rail unit 32 and the shielding surface 907 of the first side panel 901 or the second side panel 902 on the same side of the drawer 900. The deviation distance F is exactly the width (W) of the adjustable space 39, allowing the drawer 900 to be slightly adjusted left and right relative to the movable rail unit 32 and the tail hook 33. In other words, the width of the fixed rail body in the prior art is S, while the width of the fixed rail body 311 in this embodiment is T. The width increases from S to T, and the width increases by W (i.e., TS = W). Simultaneously, the tail hook 33 is offset by W towards the fixed wall 312, allowing this slide rail mechanism 300 to directly replace the slide rail mechanism of the prior art without worrying about the misalignment of the alignment hole 905. This advantage lies in retaining the existing board manufacturing dimensions on the market, while the assembly process and methods are exactly the same, providing a process that does not require retraining, avoiding changes to the assembly process, and reducing the difficulty of use.

[0056] Therefore, when the drawer 900 is installed in the slide rail mechanism 300 and is installed in the cabinet 800 in a push-pull manner, if it is found that the drawer 900 is closed, the front panel 904 of the drawer 900 (shown in...) Figure 13 If the drawer 900 cannot be smoothly and evenly placed against the front side of the cabinet 800, the adjusted drawer 900 can be positioned on the movable rail unit 32 using the adjustment mechanism 908 installed between the front end of the movable rail unit 32 and the drawer 900. Alternatively, if the width of the drawer 900 is slightly smaller due to manufacturing tolerances of the drawer 900 panel components, the adjustable space 39 between the first side panel 901 or the second side panel 902 on the same side of the drawer 900 and the movable rail unit 32 can be used as an adjustable space 39 to correct the tolerances and improve installation flexibility.

[0057] The aforementioned technology was initiated by the inventor of this case using reverse thinking. The primary solution to the problem of drawer door panels not being able to seal properly is not to increase the spring tension in Newtonian force, but to find the source of interference that prevents sealing and eliminate the source of interference. This not only avoids increasing the tension in Newtonian force, but also reduces it, thus achieving two goals at once: firstly, it solves the problem of door gaps not being able to seal properly, and secondly, it allows the drawer to be opened gently by prying it open.

[0058] Through the inventor's cross-disciplinary involvement in the furniture manufacturing industry and years of research and development on slide rail structures, it was possible to integrate and analyze the slide rail mechanism 300, which connects the furniture cabinet 800 and the drawer 900 as a storage hardware for opening and closing. The originally smooth-moving slide rail mechanism 300, connected between the cabinet 800 and the drawer 900, suffers from accumulated tolerances during manufacturing and assembly. How to eliminate the parallel compression and herringbone movement caused by external connections is considered the primary focus of the solution. Therefore, when the fixed... The fixed rail unit 31 is locked to the side wall 801 of the cabinet 800 and is in a state of immovability. If the hidden walls 321 of the movable rail units 32 on both sides are clamped by the shielding surfaces 907 on both sides of the drawer 900, the movable rail units 32 on both sides will be forced to squeeze and open by the shielding surfaces 907 due to unpredictable tolerances, and will not be able to slide smoothly with the fixed rail unit 31. Therefore, there must be an adjustable space between the two to accommodate the adjustment space required for the manufacturing assembly tolerance.

[0059] The most challenging aspect of the aforementioned improvements is that during the process of assembling the movable rail unit 32 with the drawer 900, the tail hook 33 at the end of the movable rail unit 32 must be inserted into the alignment hole 905 on the back of the drawer 900. This alignment hole 905 is drilled by using the impact indentation 909 created by the impact point 335 of the tail hook 33 as the center point for drilling. The alignment hole 905 is drilled by hand after the assembly personnel have assembled the drawer 900. The unpredictable angled hole diameter will cause the tail hook 33 of the movable rail unit 32 to be forcibly interfered with and deflected, further aggravating the mutual interference and movement between the movable rail unit 32 and the fixed rail unit 31. This is a manual drilling assembly method that has been in the market for many years and is not easy to change or retrain. Therefore, the only solution is to improve the structure of the tail hook 33 to eliminate the interference source that causes the movable rail unit 32 to deflect and move relative to the fixed rail unit 31. If the misaligned sliding rail unit 32 needs to be straightened, an adjustable space 39 must be provided. This adjustable space 39 arises from the deviation of the impact point 335 of the tail hook 33 of the improved sliding rail unit 32 from the left-right width center line 700 away from the fixed wall 312. In this way, without changing the existing process, an adjustable space 39 can be created between the hidden wall 321 of the sliding rail unit 32 and the covering surface 907 of the drawer 900, which were originally in contact with each other.

[0060] When the originally smooth slide mechanism 300 connects the cabinet body 800 and the drawer 900, which have unpredictable tolerances, the adjustable space 39 is used for adaptation adjustments to eliminate interference caused by tolerances. This eliminates the need to increase the spring tension and forcefully pull the front panel 904 of the drawer 900 (shown in the diagram) which cannot be closed. Figure 13This reduces the spring tension, allowing the drawer 900 to be opened easily by applying force with the fingertips to the small front panel 904.

[0061] In summary, the structural design of the tail hook 33, where the pointed protrusion 334 extends obliquely away from the fixed wall 312 relative to the left and right width center line 700, causing the impact point 335 of the pointed protrusion 334 to deviate from the left and right width center line 700, and the design of the movable rail unit 32 being spaced apart from the first side plate 901 or the second side plate 902 on the corresponding side of the drawer 900, allows the drawer 900 to be adjusted relative to the cabinet body 800 when the slide rail mechanism 300 of the present invention is installed in a drawer cabinet, thereby overcoming the disadvantage of interference caused by tolerances in the sliding of the slide rail mechanism 300.

[0062] Therefore, the slide rail mechanism 300 of the present invention can indeed completely improve the shortcomings of the existing slide rail mechanism 300 used in drawer cabinets. It truly achieves the purpose of the present invention.

[0063] The above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention shall still fall within the scope of the present invention.
