Abstract

This invention describes an electrically adjustable shelving system designed for ease of use, space saving, eliminating the need to retrieve items from high shelves, and reducing the risk of accidents. The system comprises a cabinet frame, guide rollers, gears, five auxiliary guide rollers and a chain, a roller shaft, a chain, shelves, and a motor. The shelving system is electrically adjustable via a motor that powers the gears, which are then connected to the chain and guide rollers. The guide rollers work in conjunction with the roller shaft to prevent chain twisting and ensure straight movement, maintaining the shelves in an upright position parallel to the floor at all times.

Claims (10)

1. Electrically adjustable shelving unit is provided by a cabinet frame (1) which is a square frame connected together on each side that serves as a frame covering the entire machine and is fitted with guide rollers (30) and guide rollers and chain (40) which serve as guides supporting the rollers (110) of the chain (70) to control and assist the chain (70) so that it does not twist and moves in a straight line as specified. The guide rollers (30) work together with the roller shaft (60) which serves as a guide for supporting the rollers (110) attached to the shelving unit (100) to control the shelving unit (100) to remain upright and parallel to the floor at all times. It has a special feature: the chain (70) transmits force and drives each shelving unit (100) to move up and down, which consists of At least one gear position, which arranges the upper gear (10) to one position as a fixed gear and the lower gear (20) to another position as a lower gear (20) connected to the shaft, acts as a power transmission from the motor to the upper gear (10) and lower gear (20) so that they can be adjusted up and down and move together by setting a screw to pull the chain (70)( mechanism). The chain pulling mechanism (70) is provided by the force of a screw pressing against the bearing housings that support the two shafts where the chain (70) is provided. At least one roller (110) is installed per axle to prevent the chain from twisting and to allow the movement to be aligned with the rollers and the chain (40) as specified, which arranges the center axle of the upper gear (10) to be positioned directly opposite. The central shaft is fitted with a bearing housing to allow the gears to rotate, and the lower gear (20) is connected by a shaft, and the upper gear (10) and lower gear (20) are connected by a chain (70) together with a long shaft (80), one side of which has a connection point. Attached to the shelf mounting plate (50), it acts as a link to the shelf (100) and to the short shaft (90) which is set to a length of 30-100 mm (mm) with a roller shaft (60) to keep the shelf (100) upright at all times and at a specified angle to the shelf mounting plate (50), allowing the roller (110) to move in the track of the roller guide (30) specifically designed along the curve of the shelf aisle (100) and the shaft, where the long shaft (80) is set to a length of 100-200 mm (mm) with at least one roller (110) and at least one common pivot point, and the height adjustment is achieved by transmission. The motor is used to transmit power to the upper gear (10) and lower gear (20). The upper gear (10) and lower gear (20) are then connected to a chain (70) attached to the rack (100) to transmit power to the main shaft. Page 2 of 2. 2. Electrically adjustable shelving equipment as per claim 1, where the appropriate cabinet frame (1) shall be made of steel and the frame shall be covered with a suitable flat sheet material, which may be wood, glass, steel, aluminum or stainless steel as the surface covering material for safety and aesthetics. 3. Electrically adjustable shelving system, as per claim 1, where the gears are appropriately arranged in 5 two positions, with two pieces installed in each position, totaling four pieces. 4. Electrically adjustable shelving equipment in accordance with claim 1, where appropriate rollers (110) are provided, two rollers (110) together with two axes. 5. Electrically adjustable shelving units, as per claim 1, where appropriate bearing housings shall be provided with 10 cylindrical roller bearings. 6. Electrically adjustable shelving equipment in accordance with claim 1, in which a suitable long shaft (80) is provided, consisting of two working shafts. 7. Electrically adjustable shelving units under claim 1, where the motor is supplied as a DC type with a power of 350 watts (w) and a gear ratio of 1:60. 8. Electrically adjustable shelving unit, as per claim 1, where the cabinet frame (1) is supplied with an additional control box for direction and speed control of the up-down movement by pressing a switch, button or remote control to control according to the user's needs. The control can be changed manually if the electrical system malfunctions. 9. Electrically adjustable shelving equipment as per claim 1, where cabinet frame (1) is further assembled with the installation of sensor curtains on the front or doors of cabinet frame (1) to prevent objects from entering and interfering with the work or to prevent accidents from being pinched on the hands. 10. Electrically adjustable shelving equipment, in accordance with claim 1, where the cabinet frame (1) is provided, can be further assembled with wheels for moving the bottom of the cabinet frame (1).
