This invention relates to certain new and useful improvements in tables, and the primary object of this invention is to provide a vertically and angularly adjustable table :5 for use in hospitals, the sick room and under other such circumstances where a table of this character will be found desirable.
-A still further object of'the invention is to provide in a table of the character above 39 mentioned, means for positively retaining the table at the position to which it may be moved. I Other objects and advantages of the invention will 'be best understood from a study of the following description, taken in connection with the accompanying drawings wherein:v I I Figure 1 is a vertical sectional elevational view through the table.
Figure 2 is a vtransverse sectional vlew taken through the line 22 of Figure 1.
Figure 3 is a bottom plan view of the table to ll igure 4 is a transverse sectional view taken substantially on the line 44 of Figure '1.
Figure 5 is a detail sectional elevational View taken substantially on the line 55 of Figure'l. c
Figure 6 is a vertical sectional elevational view taken substantially on the line-66 of Figure 5.
Figure 7 is a fragmentary elevational yiew showing the table top in horizontal position by 'full line and in a vertical position by dotted lines. I
Figure 8 is a horizontal transverse sectional view taken substantially on the line 8-8 of Figure 1.
With reference more in detail to the drawings, it will be seen that the table comprises what may be termed a carriage, consisting of a bar 10, at one end provided with oppositely extending curved arms 11 each of which is provided at its lower end with a roller 12. At its opposite end, the bar merges into a transverse bar 13 that at its ends is downturned, and each of. the downturned ends is equipped with a suitable roller 14.
The rollers 12 and 14 are swiveled, to facili- 1931. seriaiNo. 551,988.
tate moving of the table from one place to another.
At the junction of the bars 10 and 13, there rises a tubular standard 15, the lower end of which is received in a socket 16 provided at said junction of bars 10 and 13. Vertically slidable in the tubular member 15 is anoncircular rod 17 of hollow construction, and provided on one side thereof with a longitudinalslot 18. The members 15 and 17 provide a vertically extensible standard, the length of'which is controlled'through the medium of an adjusting screw 19 that extends through a suitable aperture in the upper end of the tubular post 15, and terminates at its inner end within the member 17 to bind against one wall of said member 17 for retaining the same at the fixed adjustment. The screw 19 is carried by a suitable collar 20 mounted on the upper end of the tubular member 15.
The upper end of the member 17 has suitably secured thereto a fixed hinge member 21 to which is hinged or pivotally connected as at 22 a complemental hinge member 23 provided on one end of a rod 24. Rod 24 is normally retained in a siibstantially horizontal position, through the medium of a'latch 25 'pivotally carried by the hinge member 23 and engageable with a keeper 26 provided on the hinge member'21. See Figure 1.)
The rod 24 supports what may be termed a table top 27, the latter being in the present instance, in the nature of a substantially elongated rectangular board, formed of wood, m'etal, porcelain or any other suitable material. The board '27 on the under face thereof is provided with a pair of longitudinally alined relatively spaced bearings 28 which receive theirod 24, and suitable collars 29 are provided on the rod 24 adjacent the bearings 28, whereby to retain the table top 27 against longitudinal shifting movement relative to the rod 24. j
The table top 27 maybe retained at the 9 desired angular adjustment relative to the perpendicular, and when rotated about the axis of the rod 24, through the medium of a circular rack plate 30 provided on that hearing collar 28 nearest to the hinge member 23.
Cooperating with the rack plate30 is an adjusting screw 31 that is threaded through alug 32 provided on the hinge member 23. (See Figure 7.)
From what has been hereinbefore stated, it will be seen then that the height of the table may be adjusted through the medium of the member 17 sliding in the member 15, and the screw 19 for engaging the member 17 It is also apparent, that the angularity of the table top 27 relative to the bar 24 may be fixed by elements 30,31.
To retain the table, or more specifically to retain the carriage forming part of the structure, against casual displacement, after it has once been wheeled to the desired location, I have provided a suitable brake structure which in the present instance comprises a pair of relatively spaced vertical sleeves or sockets 33 depending from the cross bar 13, and arranged in each of the sockets 33 is a plunger 34 normally urged downwardly and outwardly of the sleeve or socket through the medium of a spring 35. (See Figure 6.)
The outer lower ends of the plungers 34 are connected by a cross bar 36, which at each end thereof is provided with a surface contacting shoe 37. The lower end of each shoe 37 may be covered with rubber, leather or other suitable material so as not to mar highly polished floors or like surfaces.
Mounted to operate in the tubular post 15 and the member 17, is a control rod 38, which at its lower end is connected to an intermediate portion of the cross bar .36 as at 39, while the upper end of the rod 38 is pivotally connected to one end of a lever 40 that is pivotally mounted between parallel ears 30 provided on the collar 20. The end of the lever 40 that is engaged with the control rod 38 extends through an opening in the post 15, and through the slot 18 of the rod 17.
The rod 38 is normally retained in a retracted position, that is in the position shown in Figure 1, through the medium of a latched dog 42 that is pivotally carried by the lever 40, and which is engageable with a suitable catch member provided on the collar 20 between the ears 20 as at 43. The latch 42 is normally urged, through the medium of a spring interposed between the free end thereof and the lever 40, into engagement with the catch member 43. (See Figure 1).
From the foregoing then it will be seen that normally the lever 40 is retained in the position shown in Figure 1, whereupon the plungers 43 are retracted within their sleeves and the members 37 are held out of engagement with the ground. Then the table has been moved to the desired location, latch .member 42 is'moved out of engagement with the keeper 43 whereupon the lever 40 is swung about its pivot and the springs 35 are free to act on the plungers 34 urging the same downwardly of their sleeves, and forcing the members 47 into frictional contact with the fioor or like surface whereupon the table is held against casual movement.
It is thought that from the foregoing, taken in connection with the accompanying drawings, that a clear understanding of the construction, utility and advantages of a table of this character will be had by those skilled in the art without a more detailed description.
sprmg pressed plungers arranged in said sleeves and normally urged downwardly, a bar connecting said plungers, and means on said bar for frictional contact with the ground, and manual means for retracting said plungers, said last mentioned means including a tubular standard rising from the carriage, a lever pivotally mounted on said standard, a link connecting said lever with the bar connecting said plungers, and latch means for locking said lever against swinging movement.
2. A table including in combination, a standard, including a fixed member and a slidable member arranged in the fixed member, said fixed member provided with a relatively short slot, said slidable member provi ded with a relatively elongated slot, an adjusting screw carried by the fixed member and extending into the slot of the slidable member for engagement interiorly with said slidable member to retain the same in the desired adjustment, a lever pivotally mounted on said fixed member and having its end extending through said elongated slot into said slidable member, vertical shiftable breaking means, a link connecting said means with said end of said lever and extending lon itudinally and interiorly of said fixed an slidable members and latch means for retaining said lever against casual swinging movement.
3. In a device of the character described, in combination, a carriage, rollers supporting said carriage, a vertically adjustable standard mounted on the carriage, a table top mounted on the standard for angular adjustment, and brake means for the carriage connected with said plunger, a lever pivotally mounted on said standard, means operatively connecting said lever with the ground engaging means, and inter-engaging means on said lever and standards for normally retaining the ground engaging means in elevated position against the "action of said spring.
