[0033] As described above, the 'stepless bellows cover' (200) of the present invention includes a bellows cover (210), a mating cover (220), a fixed rail (230), a knob (240), a housing (250), a variable rail (260), and a fixing means (270).

[0034] The housing (250) is a body capable of storing a cup holder or tray provided in the interior of a vehicle, and the driver or passenger riding in the vehicle stores and stores items.

[0035] The fixed rail (230) has the shape of a plate and is provided on both sides of the housing (250), and includes a ‘folding cover rising guide hole’ (231) and a control projection (232).

[0036] The above bellows cover rising guide hole (231) is provided in front of the fixed rail (230) and has a through hole formed in an arc shape in the upward direction, so that a guide projection (262) described later is inserted and functions as a passage for moving in the upward or downward direction.

[0037] The above control projection (232) is provided at the rear of the fixed rail (230), and a control inclined surface (232a) is formed at the front of the control projection (232), so that it is provided inside the cut groove (263) of the variable rail (260) described later and makes sliding contact with the cut inclined surface (263a).

[0038] The variable rail (260) is provided in the inner direction of the fixed rail (230) and includes a moving guide groove (261), a guide projection (262), and a cut groove (263).

[0039] The above-mentioned moving guide groove (261) is provided in the shape of a groove recessed in the longitudinal direction on the inner side of the variable rail (260), and has a guide function for opening or closing the housing (250) by means of the bellows cover (210) by inserting and moving bellows protrusions (211) provided on both sides of the bellows cover (210).

[0040] The above guide projection (262) is provided in a shape protruding from the front outer surface of the variable rail (260) and is inserted into the ‘bellows cover rising guide hole’ (231) formed in the fixed rail (230).

[0041] When the bellows cover (210) is closed, such a guide projection (262) rises along the ‘bellows cover rising guide hole’ (231), thereby raising the variable rail (260) connected to the guide projection (262). When the variable rail (260) rises, the bellows projection (211) inserted into the movement guide groove (261) of the variable rail (260) and the bellows cover (210) connected to the bellows projection (211) rise, thereby allowing the bellows cover (210) and the opposite cover (220) to maintain a horizontal state.

[0042] That is, the bellows cover (210) and the counterpart cover (220) form a stepless gap with the counterpart cover (220) when the bellows cover (210) moves in a sealed state.

[0043] The above-mentioned cut groove (263) is provided in the shape of a cut groove at the rear of the variable rail (260), and a cut inclined surface (263a) is provided at the front of the cut groove (263) so as to make sliding contact with a control inclined surface (232a) provided at the front of the control projection (232) of the fixed rail (230).

[0044] If we look at the operational relationship of such an incision groove (263),

[0045] When the bellows cover (210) moves in a closed state, the cut slope surface (263a) provided in the cut groove (263) of the variable rail (260) rises while sliding in contact with the control slope surface (232a) of the control projection (232), thereby causing the variable rail (260) to rise, and when the variable rail (260) moves in an open state, the cut slope surface (263a) of the cut groove (263) descends while sliding in contact with the control slope surface (232a) of the control projection (232), thereby causing the variable rail (260) to descend.

[0046] In addition, the length (ℓ2) of the control projection (232) is characterized by being formed to be longer than the length (ℓ1) between the bellows projections (211). By specifying that the length (ℓ2) of the control projection (232) is longer than the length (ℓ1) between the bellows projections (211) in this way, the problem of the control projection (232) being inserted between the bellows projections (211) and causing malfunction can be resolved.

[0047] The bellows cover (210) is provided with bellows protrusions (211) on both sides, and the bellows protrusions (211) are inserted into a moving guide groove (261) formed in the variable rail (260) and move, thereby moving the bellows cover (210) in a direction to open or close.

[0048] The knob (240) is provided on the front upper surface of the bellows cover (210) and includes a bottom plate (241) and a protrusion (242).

[0049] The above-mentioned bottom plate (241) has the shape of a plate and is fixed to the front upper surface of the bellows cover (210). Since such a bottom plate (241) has a large surface area and is fixed to the upper surface of the bellows cover (210), it has the function and effect of improving the bonding strength between the bottom plate (241) and the bellows cover (210).

[0050] The above-mentioned protrusion (242) protrudes from the upper surface of the base plate (241) and has the function of making it easy for a driver or passenger to grip. A curved surface (R) is formed at both upper ends of the protrusion (242), so that when a driver or passenger grips the protrusion (242), it has the function and effect of preventing injury to the hand caused by the angled edges.

[0051] The fixing means (270) is configured to temporarily fix the variable rail (260) so as to maintain it in a raised state by being provided on the fixed rail (230), and includes a fixing bracket (271), a support projection (272), a bending support part (273), a guide protruding pin (274), an elastic piece (275), and a ring-shaped bending part (276).

[0052] The above-mentioned fixed bracket (271) is provided on one side of the fixed rail (230) to support the elastic piece (275), and its outer surface has a shape approximately like an 'L' when viewed from the rear.

[0053] The above support projection (272) is provided in a state of protruding in an arc shape on the inner bottom surface of the fixing bracket (271) and supports one side bottom surface of the elastic piece (275) described later.

[0054] The above-mentioned bending support member (273) is provided in a shape in which a part of the inner side of the fixing bracket (271) is cut, and has the function of supporting the bent elastic piece (275).

[0055] The guide protruding pin (274) is provided on the fixed rail (230) in a protruding state, forming a certain distance from the bending support part (273), and has the function of guiding the elastic piece (275) to be bent and supported between the bending support part (273) and the guide protruding pin (274).

[0056] The above elastic piece (275) is supported on one side in contact with the support projection (272) and then bent in contact with the inner side, and is provided between the bending support part (273) and the guide protrusion pin (274) so ​​as to be bent into a shape that wraps around the guide protrusion pin (274), and the other side is given elastic force to spread out in the direction toward the bellows cover rising guide hole (231).

[0057] The above-mentioned ring-shaped bending portion (276) is provided at the end portion facing the bellows cover rising guide hole (231) of the elastic piece (275), and has the function of elastically pressing the guide projection (262) provided through the bellows cover rising guide hole (231).

[0058] That is, since the contact between the ring-shaped bend (276) and the guide projection (262) is made along the arc of the ring-shaped bend (276), sliding contact is achieved, thereby having the function and effect of minimizing contact resistance.

[0059] If we look at the operational relationship of such a fixed means (270),

[0060] When the driver or passenger grasps the knob (240) and moves the bellows cover (210) in the direction of closing the housing (250), the guide projection (262) provided on the variable rail (260) overcomes the elastic pressure of the contacted elastic piece (275) and moves, causing the variable rail (260) connected to the guide projection (262) to rise so that the bellows cover (210) and the opposite cover (220) rise without step difference.

[0061] In this state, the ring-shaped bend (276) of the elastic piece (275) elastically presses the lower bottom surface of the guide projection (262), thereby temporarily fixing the bellows cover (210) to maintain a closed state.

[0062] When opening the bellows cover (210), if the driver or passenger grasps the knob (240) and moves the housing (250) in the direction of opening, the guide projection (262) overcomes the elastic pressure of the ring-shaped bending part (276) and descends along the bellows cover rising guide hole (231), thereby allowing the bellows cover (210) to be opened while lowering the variable rail (260).

[0063] The present invention, as described above, combines the effects of excellent design and appearance quality with the effect of preventing foreign substances from accumulating on the bellows cover. Explanation of the symbols
