This support apparatus includes a fixation member and a support member attachable to and detachable from an opening portion of the fixation member. A first upper surface portion of the opening portion is formed of: a first front surface portion sloped in a downward direction; and a first rear surface portion formed continuously from the first front surface portion and sloped in an upward direction. A first lower surface portion is sloped in parallel with the first front surface portion. A second upper surface portion of the support member is formed of: a second front surface portion to contact the first front surface portion; and a second rear surface portion to contact the first rear surface portion. A second lower surface portion is sloped in a downward direction, at a slope angle, so as to contact with an opening-side end of the first lower surface portion.

Various embodiments of the present invention are directed to an apparatus comprising a heavy duty shelving assembly. The apparatus comprises shelving assemblies that may be used to store relatively heavy objects such as vehicle components, athletic weights, or the like. The apparatus comprises a plurality of vertical columns including column members that are selectively coupled to one another, a plurality of horizontal supports that extend between the column members, and a plurality of shelves that are positioned on the horizontal supports. The apparatus may also include a center brace extending between opposing horizontal supports. The horizontal supports include a truss portion connected to a support portion; the truss portion distributes the downward forces applied to the support portion by the shelves. The design of the apparatus and the truss increases the downward forces that may be applied to the shelf, thereby increasing the weight capacity of the shelves and the apparatus. The column members are configured for selective coupling by incorporating a main portion that comprises a plurality of apertures and a coupling portion that extends outward from the main portion such that it may accept at least part of a main portion of an adjacent column member. The coupling portion further comprises one or more engagement tabs that are configured to engage the apertures of an adjacent column member. In at least one embodiment, the engagement tabs are formed through stamping, thereby minimizing or entirely eliminating areas where stress can concentrate when the apparatus is under load. This feature reduces or eliminates the potential of a partial failure when the apparatus is under load.

A chassis quick release device includes a housing including a base provided with a sliding channel, a compression space, and accommodating space, a rotating space and a shaft in the rotating space and covered with a cover, a locking block linearly movably set in the accommodating space and providing a guide groove, a guide chamber, a receiving groove and an elastic member set in the receiving groove, a locking member having a shaft hole coupled to the shaft, a rotary reset member positioned on the shaft, resisting edge located at one end thereof that can rotate and protrude from the housing and a locking edge located at the other end thereof, and an operating handle including a rod body positioned in the sliding channel, the guide groove and the guide chamber and mounted with a grp and having a locking portion stopped against the guide chamber.

A fixture member includes: a pillar having a substantially horizontal sectional shape that is a U-shape; a plurality of chip portions fixed in the pillar; and an opening formed by a lower surface of one chip portion, an upper surface of another chip portion, and opposed inner side surfaces of the pillar. A support member is detachably attached to the opening. A receiving member is fixed to the support member. The chip portion has an upper slope surface, a first horizontal surface, and a lower slope surface. The support member has: a first contact surface to contact with the lower slope surface; a second contact surface to contact with the upper slope surface; a third contact surface to contact with the first horizontal surface; and a fourth contact surface and a fifth contact surface to contact with the opposed inner side surfaces of the fixture member.

This support apparatus includes a fixation member and a support member attachable to and detachable from an opening portion of the fixation member. A first upper surface portion of the opening portion is formed of: a first front surface portion sloped in a downward direction; and a first rear surface portion formed continuously from the first front surface portion and sloped in an upward direction. A first lower surface portion is sloped in parallel with the first front surface portion. A second upper surface portion of the support member is formed of: a second front surface portion to contact the first front surface portion; and a second rear surface portion to contact the first rear surface portion. A second lower surface portion is sloped in a downward direction, at a slope angle, so as to contact with an opening-side end of the first lower surface portion.

A fixing device for a safety screen includes a bracket, a support member and a locking member. The support member includes a plurality of openings, and two of the openings include keyhole slots that are spaced from one another along the support member. Each of the keyhole slots include an enlarged portion and a slot. The bracket includes at least one engagement member that has a shank portion and a head. The head is receivable through the enlarged portion thereof. The shank portion is receivable by the slot of any of the keyhole slots, and the locking member is attached to the bracket. The bracket is engageable with the support member by inserting the head through the enlarged portion. The locking member is engageable with the support member following translational movement of the engagement member along the slot, the locking member thereby locking the engagement member against translational movement.

A shelving system includes a support structure, one or more shelf units, and a plurality of load pins. The one or more shelf units are configured to couple on the support structure. At least one of the shelf units includes a shelf platform, and two or more brackets coupled to the shelf platform. At least one of the brackets includes a body and defines an opening having a main slot, and two or more stopping position branch slots adjoining the main slot. Each of at least one of plurality of load pins is coupled between one of the two or more brackets and the support structure such that the bracket is moveable to shift the load pin from one stopping position branch slot to another stopping position branch slot to adjust the position of the shelf unit while the shelf unit remains partially supported by the support structure.
