This invention relates to bedside tables zontal positions and which is also shiftable vertically for adjusting its height.
The main objects of this invention are to provide a bedside table having an improved form of support for the tray; to provide improvedmeans for retaining the tray in a horizontal position; to provide improved mechanism for elevating said tray support; to provide improved latching means for securing the tray support in various elevated positions; and to provide a bedside table of this kind wherein the elevating mechanism --and latching means may be operated with one foot. 7 p
An illustrative embodiment of this invention is shown in the accompanying drawing,
1'. wherein Figure l is a side elevation of an improved bedside table with thetray in its lowermost horizontal position; the dotted lines showing the tray'in its retracted position.
Fig. 2 is a rear elevation of the table with the tray retracted and partly broken away. Fig. 3 is a front elevation of the lower Fig. 4: is a fragmentary horizontal section, taken on the line 4-4 of Fig. 1. a
Fig. 5 is an enlarged fragmentary vertical 'sectiontaken on the line 5-5 of Fig. 2, the
dotted lines showing the parts in changed positions. Y r
In the form shown, the improved table comprises an upright cabinet, on which is mounted a vertically movable support which carries a hinged tray and which is elevated by improved pedal actuated mechanism located below the cabinet.
The cabinet comprises an uprlght frame 1 mounted on legs 2 andhaving a top 3, rear wall 4, side walls 5, and a front door 6. Mounted on the rear wall of the cabinet, is an upright guideway for guiding the vertically movable tray support.
In the form shown, the guideway com-- prises a plurality of guide rollers 7 supon horizontal shafts 8, which are 1929. Serial n6. ssasoe.
mounted on a channel member 9 secured to the rear Wall/l: by any suitable means; Secured to the channel member 9, is a vertically disposed plate 10, on which is mounted a pair of buffers 11 adapted to engage the'hinged' tray when the tray. is retracted.
In the construction illustrated, the-tray support comprises a pair of upright rods 12 extending through the channel 9 in slid ing. engagement with the roller 7. The upper ends of the rods 12are seated in sockets 13 of a bearing. member 14, which is provided with depending lugs-15 for sup- 7 porting a hinged tray 16. Thelugs 15 form keepers for engaging the latching means of the tray and, for this purpose, are provided with notches 17 and arcuate approaches 18.
In the form shown, the tray 16 has a depending peripheral flange 19. Mounted on the lower face of the tray, is a pair of substantially parallel bars 20, which project beyond the inner end of'the tray for connection to hinge pins 21 supported in the lugs 15.
Located between the'two bars 20, is an axially movable detent. 22 which is supported in guides 23 and 2e mounted on the lower face of the tray. Formed on the inner end of the detent 22, is a cross bar 25 which is adapted to engage the notches 17 of the keeper for supporting the tray in a horizontal position as shown in Fig. 1. When the tray is retracted, the cross bar 25 engages, the approaches 18. Embracing the detent 22, is a spring 26 which bears between the guide 2 1 and a pin 27 mounted on the detent for normally urging the cross bar25 into engagement with the Keeper. Mounted on the outer. end of the detent, is a handle 28 by which the detent may be manually retracted from the keeper.
'That'portion of the peripheral flange 19 which is located adjacent the handle 28, forms-a hand rest 29 againstwhich the palm of the hand may hear when the fingers are hooked around the handle 28. 1
In the form shown, the improved elevating mechanism comprises a pedal '30 hinged ona pin 31' secured to the lower end of a bracket 32, which is supported on the bottom of the cabinet frame 1. The rear end of the pedal 30 is pivotally secured to the lower ends of a pair of links which are hinged to the lower ends of the bars 12. The for- Ward end of the pedal has a foot rest 34:.
In order to secure the table in an elevated position, improved means are provided for retaining the pedal 30 in a depressed position. In the form shown, the retaining means comprises a pedal 35, which is hinged to the elevating pedal 30 by a pin 36. Mounted on the outer end of the pedal 35. is a foot rest 37 which is located adjacent the foot rest 34, so as to permit the operator to place one foot simultaneously on both pedals.
Formed on the inner end of the pedal 35, is a plurality of notches 38, which are adapted :to receive a horizontal rod 39, supported on the bracket 32, when the elevating pedal 30 is depressed. A depending yoke 40 is secured to the inner end of the pedal 35 for engagement with the lower side of the rod 39 to prevent the inner extremity of the pedal 35 from striking the bottom of the cabinet when the foot rest is depressed.
In operation, to extend the tray, it merely swung around its hinge until the crms bar engages the notches 17. To
elevate the tray, the pedal 39 is depressed,
whereupon the rear end of the pedal 35 rides over the rod 39. When the pedal is depressed to the desired position, the rod 39 engages one of the notches 38 and the pedal serves as a brace for securing the edal 30 in its depressed position. lVhen it is desired to lower the tray, one footis placed upon both of the pedal rests 34 and 37 and, by slightly tilting the foot, the pedal 35 may be depressed for releasing it from the rod 39. The foot may then be slowly raised to permit both pedals to rise to the position shown in full lines in Figs. 1 and 5.
Although but one specific embodiment of this invention has been herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.
I claim 1. A bedside table comprising a frame, a vertically movable support mounted on said frame, a tray on said support, and a pedal hinged on the lower end of said frame, one end of said pedal supporting said tray support wherebythe depression of the opposite end of said pedal elevates said support and tray relative to said frame.
2. A bedside table comprising a frame, a vertically movable support mounted on said rrame, a. tray on said support, a shoulder on said frame, a pedal hinged on the lower end of said frame and operatively connected to said support for elevating said support and tray relative to said frame, and a latch bar hinged on said pedal and adapted to engage said support in various elevated positions.
4. A bedside table comprising an upright frame, a vertical guideway on said frame, a support movable vertically on said guideway, a tray on said support, a bracket 0n the bottom of said frame, a rod on said bracket, a pedal hinged on said bracket and pivotally connected to said support, said pedal being adapted to be depressed for elevating said support and tray relative to said frame, and a latch bar hingedon said pedal and adapted to engage said rod for securing said pedal in a depressed :position.
5. A bedside table comprising an u right frame, a vertical guideway on said rame, a support movable vertically on said guideway, a tray on said support, a bracket on the bottom of said frame, a rod on said bracket,
a pedal hinged on said bracket and pivotally connected to said support, said pedal being adapted to be depressed for elevating said support and tray relative to said frame, anda multiple stop latch bar hinged on said pedal and adapted to engage said rod for securing said pedal in various depressed positions.
6: A. bedside table comprising a frame, a vertically movable support mounted on said frame, a tray on said support, a pedal hinged on the lower end of said frame, and a link hinged to said support and to one end of said pedal. whereby the depression of the opposite end of said pedal elevates said sup- :port and tray relative to said frame.
