Abstract: A combination tool caddy and stool comprises a base, having a pedestal-type seat mounted on a central portion of the base. A vertical support post is mounted on a marginal portion of the base in a laterally spaced apart relationship with the seat. A tray is supported on the vertical post in a horizontal orientation by an adjustable coupling which permits the tray to be moved vertically and horizontally to a location that is conveniently reachable by a user seated on the seat. The tray can also be mounted on the support post in a vertical orientation to form a backrest for the seat. The seat and the tray are preferably attached to the base by interchangeable coupling members, so that the seat can be removed, and the tray supported on the center of the base to provide additional stability. Wheels may be provided on the base so that the unit can be manually propelled by a seated user from one work site to another.

Abstract: A folding bench/table combination including two spaced apart leg assemblies, each including a horizontal, forwardly extending seat support member, a seat leg pivoted to the rear end of the seat support member, a table leg pivoted midway along its length to the front end of the seat support member, a table support member pivoted to the top of the table leg, and an adjuster pivoted to the table support member and extending to the pivot point of the seat support member and the table leg, and being operable to be secured in a plurality of positions to orient the table top as a table, or as the back of a bench, or in conjunction with the entire assembly being operable to be folded flat for compact stacking and storage.

Abstract: A lock release for folding tables and shelves in which the locking mechanism to prevent accidental pivoting of the top from a horizontal unfolded position to a generally vertical folded position includes a pivotal link member with guiding edges or surfaces for slidably directing a connector element along the link as the top is folded and unfolded. Most advantageously, the lock is double-acting--that is, two distinct manipulations are required to release the locking mechanism. In a preferred embodiment, the link member has an L-shaped guide slot with an elongated main portion and a relatively short end portion. When the top is horizontal, the connector element is located within the slot's end portion and, to permit the connector element to enter the elongated main portion of the slot, the link member must be shifted about its pivotal axis by the user.

Abstract: Multipassenger aircraft seat has at least one seating position which can be converted from a seat to a cocktail table to increase the comfort of adjacent seat passengers. The headrest pivots about 180.degree. relative to the back cushion frame so that it becomes hidden under the back cushion frame and in compressed contact with the lower seat cushion when a cocktail table on the back cushion frame is deployed in a horizontal plane. Concealed locks inside the headrest permit the headrest and back cushion frame to be firmly locked to the reclinable main seat back frame.

Abstract: Convertible aircraft passenger seat can be quickly changed from a three-seating position configuration to a more spacious two-seating position configuration without the use of tools. Such a seat permits the seating capacity of an aircraft to be altered to match the expected passenger load in different classes, such as tourist and business class. In the three-position configuration, a pair of relatively narrow width armrests, which may contain recline lock control cables or audio cables, project vertically out of the lower seat cushion on either side of the center seating position but are pivotally mounted so that they will overlie the center position in a generally horizontal fashion in the two-position configuration, thus adding several inches of width to the adjacent end seating positions.

Abstract: This work station is comprised of support legs (P) with a stable support base (1a) and uprights (1b) on which pivoting elbows are adapted to form adjacent arms (2a-2b) which are positioned and locked in place in an adjustable angular manner at one end of these arms, the other end bearing supports or work tops (3 and 4) positioned and locked in place in a manner which can be angularly adjusted at will, so that these supports or work tops (3-4) allow effects and uses which are multiple and can be combined together.

Abstract: A two position seat assembly is disclosed for use on a material handling vehicle. The seat assembly has a seat back section which pivots to be used as a back rest or as an elevated seat for facing the rear of the vehicle. This permits the vehicle operator to face forward to operate forward mounted equipment or to face backward to operate rearward mounted equipment.

Abstract: Table top support arms are pivoted to a base frame and extend above and below it. The lower ends of the support arms are connected through linkages with picnic table bench sections having sliding engagement with the base frame. When the support arms are tilted in one direction on their pivots, the linkage draws the bench sections together to produce a single bench bottom and the table top which is pivotally supported on the support arms is swung to a back rest forming position. Stop elements on the support arms limit the swing of the support arms and also position the back rest and table top component.

Abstract: An improved multi-purpose piece of furniture which is usable as a chair and as a step-ladder. The arrangement has a base frame and a backrest which is pivotally mounted on the base frame and adapted to be folded from a backrest position to a step-ladder position and vice versa for respective use as the top rung of the step-ladder when it is in a horizontal position and as the backrest of a chair when it is in the backrest position. The arrangement includes a pair of connected frame members forming the base frame. A plurality of rungs are operatively mounted on one of the frame members. The top rung of these rungs is adapted to alternately and selectively form a backrest or a step-ladder rung. An imaginary vertical plane passing through bottom rear edge of the backrest, when it is in the step ladder position is disposed in front and spaced from the front edge of the bottom rung which is connected on the one frame member.

Abstract: A vehicle for use in underground mining operations is disclosed which is adapted for ready conversion between personnel and materials transportation by the provision of a movable flat panel type platform or platform element movable between a first position, corresponding to a personnel transportation mode of operation, and a second position, corresponding to a materials transportation mode of operation. A bar type member extends from a seat structure transverse to its longitudinal direction which coincides with the longitudinal axis of the vehicle. The bar type member provides a horizontal support surface along with the top of the seat structure for supporting the platform in its materials transportation mode of operation. The seat structure comprises a pair of seats arranged in back-to-back relationship along the longitudinal axis of the vehicle and includes a space therebetween for the storage of said platform means in the personnel carriage mode of operation.
