Detailed Implementation

[0028] Figure 1The diagram illustrates a track according to some embodiments of the present invention. The track provided by the present invention includes a track sidewall 101, a groove 102, an upper groove wall 103, and a lower groove wall 104. The upper groove wall 103 and the lower groove wall 104 are connected to the track sidewall 101. Preferably, the upper groove wall 103 and the lower groove wall 104 are integrally formed with the track sidewall 101. The track may include a lightweight material such as an integrally formed plastic track, metal track, or carbon fiber track. The plastic track includes ABS track or other engineering plastic tracks, and the metal track includes aluminum alloy track. Optionally, other plastic materials may also be used; the present invention does not limit this. The track provided by the present invention has its groove smoothed during processing, resulting in a smooth surface and eliminating the need for lubrication during use as it does not employ a mating structure between inner and outer rails.

[0029] To more clearly illustrate the positional relationship between the track sidewall 101 and the slide 102, the upper wall 103 of the slide 103, and the lower wall 104 of the slide in this utility model, Figure 2 A side view of a track according to some embodiments of the present invention is shown.

[0030] A retaining edge 105 is provided on the lower wall 104 of the slide groove at the entrance of the slide groove. The retaining edge 105 is used to cooperate with the limiting structure on storage accessories such as drawers and trays, so as to restrict the sliding of the storage accessories relative to the track at a specific position when the storage accessories are placed into the furniture along the track in this utility model. The side of the retaining edge 105 facing the entrance of the slide groove may be provided with an inclined surface. By providing this inclined surface, the storage accessories can be prevented from being blocked by the retaining edge 105 when they are placed into the furniture along the track, thus avoiding jamming. The cross-sectional shape of the retaining edge 105 may include: wedge, triangle or trapezoid.

[0031] In some embodiments, the upper wall 103 and the lower wall 104 of the slide groove form a retractable portion 106 within the slide groove 102. The retractable portion may be located at the middle and rear of the slide groove on the track. The retractable portion 106 includes an opening area 1061 and a damping area 1062. The opening area 1061 includes a first inclined surface 1031 formed by the upper wall 103 of the slide groove and / or a second inclined surface 1041 formed by the lower wall 104 of the slide groove, both of which are inwardly inclined surfaces. The damping area 1062 includes a first protrusion 1032 formed by the upper wall 103 of the slide groove and / or a second protrusion 1042 formed by the lower wall 104 of the slide groove. The first protrusion 1032 and the second protrusion 1042 are protrusion structures that protrude from the upper wall 103 and the lower wall 104 of the slide groove towards the slide groove 102, respectively. The protrusion structure makes the slide groove 102 at the corresponding position narrower, reducing the gap between the slide groove wall and the corresponding structure on the storage accessory (e.g., the sliding edge on the storage accessory, the clip on the storage accessory, etc.), reducing the vibration amplitude of the storage accessory, playing a damping role in the process of moving furniture, reducing the vibration of items stored in the storage accessory, and reducing the noise generated during the movement of furniture.

[0032] In this application, the first protrusion refers to a protrusion in the groove from the upper wall to the lower wall of the groove, and the second protrusion refers to a protrusion in the groove from the lower wall to the upper wall of the groove. The inward slope in this application refers to the transition slope from the upper wall and / or the lower wall of the groove to the first protrusion and / or the second protrusion in the damping zone. It plays a transition role when the corresponding structure of the storage accessory enters the damping zone along the groove, so as to avoid being blocked by the protrusion and getting stuck.

[0033] According to some embodiments of this utility model, the type of track may include a left-right symmetrical track (such as...). Figure 1 As shown, the symmetrical tracks eliminate the need to distinguish track directions or pair them during installation, improving installation efficiency and saving installation time. They can also be used in display cabinets, shelves, and other furniture where items are stored on both sides. When the tracks have a symmetrical structure, the retractable section is located in the middle of the symmetrical groove.

[0034] In other embodiments of this utility model, the upper wall of the slide groove may be provided with a first groove 107 and / or a second groove 108 at the entrance of the slide groove. The depth of the first groove 107 is greater than that of the second groove 108. The first groove 107 and the second groove 108 can be used to cooperate with clips installed on both sides of the storage accessory or at least two of the four corners of the storage accessory to realize the angled storage of the storage accessory on the furniture. Figure 3This is a schematic diagram illustrating angled storage according to some embodiments of the present invention. Angled storage involves placing the storage accessory 301, such as a drawer or medicine tray, at a certain angle to the furniture by locking it in the first groove 107 or the second groove 108 when it is pulled out of the slide. Angled storage facilitates the process of users finding items in the storage accessory 301 without having to support or pull it to prevent it from slipping. For example, when medical personnel use a medication cart, they can temporarily angle the medicine tray on the cart using the first or second groove to find the required medication.

[0035] According to some embodiments of the present invention, a third groove 109 may be provided on the track sidewall between the chute inlet and the opening area. The setting of the third groove 109 can effectively disperse stress, reduce the deformation or damage of the track sidewall 101 caused by uneven force during use, and enhance the structural strength and stability of the track in the present invention.

[0036] The track provided by this utility model can include two installation methods: nail-mounted installation and nail-free installation. Figure 4 The diagram illustrates a track with nails installed according to some embodiments of the present invention. The track sidewall can be provided with screw holes 401, and the nail installation method includes screw installation, bolt installation, and rivet installation. Simultaneously, a positioning structure 402 can be provided on the sidewall of the track away from the slide groove. The positioning structure includes at least one of a positioning post, a positioning piece, or a positioning block. The positioning structure 402 can cooperate with positioning holes, positioning grooves, column edges, etc., on furniture to play a positioning role during track installation.

[0037] Figure 5 This is a schematic diagram of nail-free installation of a track according to some embodiments of the present invention. On the nail-free track of the present invention, mounting claws 501 are provided at both ends of the sidewall of the track away from the slide groove. The mounting claws are used for nail-free installation of the track, and their shape may include a "T" shape. During installation, after inserting the mounting claws into the nail-free installation holes 502 on the furniture and pulling the track downwards, the mounting claws 501 can hook onto the nail-free installation holes 502. Figure 6 The diagram shown is a nail-free installation state of a track according to some embodiments of the present invention. When it is necessary to remove the track, the mounting claw can be separated from the mounting hole by lifting the track upward.

[0038] This utility model also provides a support track plate, which is integrally formed from multiple tracks according to the above embodiments. The support track plate includes multiple tracks arranged vertically and parallel to each other. The tracks can be equidistant to accommodate storage accessories of equal height, or the spacing between the tracks can be flexibly adjusted during manufacturing according to the height requirements of different storage accessories. The integrally formed support track plate of this utility model can reduce installation gaps. Fewer installation gaps mean fewer hard-to-clean areas, reducing the difficulty of cleaning the corresponding furniture storage space.

[0039] This application also claims protection for a locking device that cooperates with the track having a first groove and a second groove in the above embodiments to achieve angled storage of storage accessories. The locking device is located at at least two of the four corners or the edge of the storage accessory. When the storage accessory is pulled out, by engaging the locking device into the first or second groove, the storage accessory can be placed at a certain angle to the furniture. This eliminates the need for the user to support the storage accessory when searching for items, improving the efficiency of item retrieval; it also allows the storage accessory to be pulled out and placed during operation. The angle of angled storage in this invention can be adjusted by adjusting the first / second groove and the locking device; this invention does not limit this adjustment.
