LOWERABLE COMPARTMENT FOR CABINETS Filed Oct. 16, 1961 2 SheetsSheet 2 INVENTOR. FIG. 2 LEO A. STEBBINS ATTORNEY United States Patent Ofiice 3,081,138 Patented Mar. 12, 1963 LOWERABLE COMPARTMENT FOR CABINETS Leo A. Stebbins, 859 S. University, Denver, Colo. Filed Oct. 16, 1961, Ser. No. 145,228 Claims. (Cl. 312-319) It is often exceedingly diflicult for the average housewife to reach the upper shelves and upper compartments of conventional kitchen cabinets due to their extreme height above the floor. It has, therefore, been found necessary to provide ladder stools and the like in kitchens for this sole purpose.
This invention relates to means for eliminating the excessive reaching usually required with relatively high kitchen cabinets and relates more particularly to lowerable upper cabinet compartments of the type illustrated and described in applicants prior Patent No. 2,555,254.
The principal object of this invention is to provide a simple, economical, and highly efficient, foldable cabinet compartment support which can be quickly and easily applied to an elevated compartment of a cabinet which will enable the entire compartment to be readily lowered within easy reach and thence returned to its elevated position in the cabinet with a minimum of manual effort.
Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efficiency. These will become more ap parent from the following description.
In the following detailed description of the invention, reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.
In the drawing: a
FIG. 1 is a perspective view of a cabinet with the invention applied thereto showing an upper cabinet compartment as it would appear when lowered within easy reach through the medium of this invention;
FIG. 2 is a side elevational view of the compartment of FIG. 1 partially broken away to show theinterior construction and showing in solid line the. upper cabinet compartment in its normal elevated position and in broken line an intermediate forward position of the lowerable cabinet compartment;
FIG. 3 is an enlarged fragmentary sectional view taken on the line 33, FIG. 2; and
FIG. 4 is a fragmentary, enlarged, detail, perspective view of a type, of spring employed in this invention.
In the drawing, a modular section of a kitchen cabinet is illustrated having side walls 10, a back wall 11, and a top plate 12. The lower main portion of the cabinet may be closed at its top by a dividing plate 15and may contain the usual cabinet shelves. The main portion is closed by doors 13 hinged to the side walls at 14. The upper portion of the cabinet is open at the front to receive a movable upper compartment 16 preferably provided with front doors 17, hinged thereto at 18, and a pull handle 41.
This invention relates more particularly to mounting means for securing the movable upper compartment to the main cabinet so that it may be lowered to a position in front of the main doors 13, as shown in FIG. 1, or raised into place in the open upper portion of the cabinet, as shown in FIG. 2.
The improved compartment mounting means employs two similar, but of opposite hand, fixed mounting plates 19, adapted to be attached, by means of suitable screws 20, to the inside faces of the side walls 10 and against the back wall 11 and the top plate 12.
A first torque rod 21 extends between the fixed mounting plates 19. The extremities of the torque rod 21 are reduced in diameter to provide terminal studs 22 which pass through and are rotatably mounted in the mounting plates 19. The rear extremity of an upper rear parallel bar 23 is fitted over the stud 22 at each extremity of the torque rod 21 and is permanently affixed thereto inany desired manner such as by means of a weld 24. The two upper rear parallel bars are affixed to the torque rod so as to lie in common plane to rotate as a unit with the torque rod 21.
The forward extremity of each rear upper parallel bar is pivoted, on a pivot rivet 25, to the upper extremity of a vertical spacer member 26. A rear lower parallel bar 27, corresponding in length to the bar 23, is positioned below and in parallel relation to each rear upper parallel bar 23. The rear lower parallel bars 27 are pivotally mounted at their rear extremities on the mounting plates 19 vertically below the studs 22 upon suitable lower plate rivets 28 and they are pivoted at their forward extremities to the lower extremities of the spacer members 26 by means of lower spacer rivets 29.
The improved mounting means also employs two similar, but of opposite hand, movable mounting plates 30 adapted to be attached against the sides of the compartment 16 at the upper forward corners of the latter by means of suitable attachment screws 31.
A second torque rod 32 extends between the movable mounting plates 30. The extremities of the second torque rod 32 are reduced in diameter, as shown in FIG. 3, with reference to the first torque rod 21 to provide terminal studs 33 which pass through and are rotatably mounted in the movable mounting plates 30 similarly to the first torque rod 21. The second torque rod 32 lies in a clearance groove 36 in the top of the movable compartment.
An upper forward parallel bar is fitted over the stud 33 at each extremity of the second torque rod 32 and is permanently affixed thereto, such as by welding, so that the two upper forward parallel bars 34 will lie in a common plane and rotate as a unit with the second torque rod 32. The rear extremity of each upper forward parallel bar 34 is pivoted on the pivot rivet 25 on the upper extremity of the spacer member in common with the rear upper parallel bar 23.
A lower forward parallel bar 35, corresponding in length to the bar 34, is positioned below and in parallel relation to each upper forward parallel bar 34. Each lower forward parallel bar is pivotally mounted at its forward extremity on one of the movable mounting plates 30 vertically below the stud 33 on a pivot rivet 37, and is pivotally mounted at its rear extremity on one of the lower spacer rivets 29 on one of the spacer members 26 in common with the rear lower parallel bar 27.
Thus, it can be seen that with the plates 30 affixed to the compartment 16, the compartment can be shifted forward and back and raised and lowered without tilting in any direction. The parallel bars prevent forward and back tilting and the torque rods prevent lateral tilting since they force the two mounting means to always move in unison.
To relieve the weight of the compartment 16 a plurality of counterbalance strip springs 38 are provided. These springs are of a type comprising spring steel strips formed in a tight spiral coil. Withdrawal of the extremity of the strip from the coil is resisted by the tendency of the strip to resume its preformed coiled condition. The strip is arcuately bent longitudinally to maintain the withdrawn portion straight similarly to a selfcoiling steel measuring tape.
The springs 38 are coiled about, but are not attached to, the first torque rod 21 between suitable retaining washers 39 held in place at each side of the coil by means of suitable keys 40. The extremities of the spring strips are attached to the bottom of the compartment 16, as shown at 42, at the rear of the latter so as to constantly urge the compartment upwardly and rearwardly. When the compartment is in the lowered position of FIG. 1 the spring strips are bent over a spring guide member 43 extending across the cabinet at the forward edge of the dividing plate 15.
It is believed the operation of the devicecan be understood from the above description of its construction. Briefly, let us assume the compartment 16 is in the in place position of FIG. 2, and that access thereto is desired. The user simply grasps the pull handle 41 and pulls the compartment forward to the broken line position of FIG. 2. Thence, pulls the compartment downwardly .to the position of FIG. 1 for easy access to the interior.
To replace the compartment the above procedure is simply reversed.
While a specific form of the improvement has been described and illustrated herein, it is to be understood that the same may be varied Within the scope of the appended claims, without departing from the spirit of the invention.
Having thus described the invention what is claimed and desired to be secured by Letters Patent is:
