Lnnsolv, oF ennnn nnrrns, ivtIcI-irdnlv` LATCH` FOR REVOLUIBLE TABLE TOPS p Appncation inea May s,
The present invention relates to tables; and its object is, generally, to provide improved devices for holding the revoluhle tops of tables in turned positions; and further, to
1 provide brakes for such tops turning movement operable in connection with such devices.
This and any other and more specific objects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the structure and devices particularly described in the hody of this specification and illustrated by the accompanying drawings, in which:
Figure l is a top plan view of framework of a rotatable table topand a device for releasably holding the same Vin a turned position;
Figure 2 is an elevational view of the table top and its pedestal or base, shown partially in vertical section taken on line 2-2 of Figure l, with said device applied thereto;
Figure 3 is a top plan view of said framework and base with the device applied there- :til to, showing the same in another position;
Figure 4 is an elevational view thereof, the
framework being partially sectioned on line 4-4 of Figure 3;
Figure 5 is an edgewise view of the same,
partially sectioned on line 5-5 of F iOure 4; Figure 6 is a fragmentary top plan view of parts thereof partially sectioned on line 6-6 of Figure 4;
Figure 7 is a like view of the same, but
" showing` the parts in another position; and
Figure 8 is an elevational view thereof partially sectioned on line 8--8 of Figure 7.
In these drawings is shown a table structure having a central base or pedestal l and a top 2 turnable horizontally thereon about a vertical pivot pin 3. The upper end por! tion 4 of said base is circular in a horizontal plane and carries on its peripheral edge spaced keeper elements, metal plates 5 as shown, having sockets 6 which are open in a horizontal and also in a vertical directionthat is, the mouths of these sockets are open at 7 downwardly and at 8 are open outwardly in the radial direction of the Circular up- ,50 per end portion 4 of the base. These plates 193i. serial no. 536,153.
or keeper elements 5 have slide bearings 9 at the opposite sides of said sockets, which are vertically inclined and lead to themouths of the sockets.
The table top 2 in the construction shown comprises a framework composed of horizontal strips l0 lon the upper side of which is carried the top proper l1 of the table, `and on the under side of which is carried the plate l2 having downwardly convex rounded extensions iSbe-aring on the top portion 4 of the base l.
The pivot pin 3 extending through the parts 4 and l2 has at its upper end a head 14 and a washer l5 on which slidably bears the springable bifurcated inner end 16 of a brake element 17 whose angle portion 18 hears on a cam platel) to cause said end 16 to `press on `said washer and urge the table top downwardly. on the base in the position of the parts lshown in` Figures 8 and 4 thus yieldingly holding the table top against turning; but when `this brake element is slid radially outwardly its angle portion 18 moves down over the inclined side 20 of plate 19 to release the brake. i
A bar 2l is mounted at one end 22on .the top 2 and at its free end has a latch element 23 whose inner end '24 seats in the socket to hold said top against turning movement. This bar is springable in vertical and horizontal directions, thus pressing the latch elements inner end in a vertical direction as it rides on the keeper elements slide bearings 9 when the table top is being rotated, and pressing said end of the latch element in` either a vertical or horizontal direction into the socket. 1 Y, i.
This latch element has an upwardly extending hooked outer end 2G with which the downwardly extending catch 27 of an elongated element 28 is adapted to engage in the position of the parts seen in Figure 4. This element 28 in such engagement is longitudi-` nally movedoutwardly by manually 'turning the lever handle 29 to the position seenin Figures l and 2 thus sliding the brakecle-V ment l? in its' bearings 30 to release the same and moving the latch el'einents inner end out of the socket 6 and to the position shown in Figure 6, whereupon the movement o1"- the lever handle gives a lateral movement to this element 28, causing its catch 27 to move out of engagement with the hooked upper end 26 of the element 23 to release the same, as seen in Figure 7 so that the latch element may engage in the socket G when again brought into registration therewith by the turning of the table top.
The elongated element 28 forms a link pivoted at 32 on the brake element 17 and at 33 on the operating lever Q9. Although the latch element 23 is withdrawn from the sockgt 6 and is in the position shown in Figure the brake element 17 is still in operative position to yieldingly hold the table top against turning.
The invention being intended to be pointed out in the claims, is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the drawings or hereinbefore described.
I claim:
1. In a table having a base and a top turnable horizontally thereon, a device for releasably holding the top in a turned position comprising: a keeper element carried by said base having a socket open in a horizontal and in a vertical direction, and a vertically inclined slide bearing leading thereto; a latch element carried by said top spring-pressed vertically on said bearing and vertically and horizontally into the socket.
2. In a table having a base and a top turnable horizontally thereon, a device for releasably holding the top in a turned position comprising: a keeper element carried by said base having a socket open in a horizontal and in a vertical direction; a latch element carried by said top spring-pressed vertically and horizontally into. the socket.
3. In a table having a base and a top turnable horizontally thereon, a device or releasably holding the top in a turned position comprising: a keeper element carried by said base having a socket open in a horizontal and in a vertical direction; a latch element carried by said top spring-pressed vertically and horizontally into the socket; a manually operated element carried by said top having a movement in engagement with the latch element for withdrawing the same from the socket and a farther movement releasing the same.
4. In a table having a base and a top turnable horizontally thereon, a device for releasably holding the top in a turned position comprising: a keeper element carried by said base having a socket open in a horizontal and in a vertical direction; a latch element carried by said top spring-pressed vertically and horizontally into the socket; an elongated manually operated element carried by said top having a longitudinal movement in cngagement with the latch element for withremesa drawing the same from the socket and a lateral movement releasing the same.
5. In a table having a base and a top turnable horizontally thereon, a device for releasably holding the top in a turned position comprising: a keeper element carried by said base having a socket open in a horizontal and in a vertical direction; a latch element carried by said top spring-pressed vertically and horizontally into the socket; a brake for yieldingly holding the top against turning; a manually operated element connected with the brake and having a movement in engagement with the latch element for withdrawing the same from' the socket and for releasing the brake.
6. In a table having a base and a top turnable horizontally thereon, a device for releasably holding the top in a turned position comprising: a keeper element carried by said base having a socket open in a horizontal and in a vertical direction, and a vertically inclined slide bearing leading thereto; a bar springable in vertical and horizontal directions, mounted at one end on said top and having at its free end a latch element pressed by said bar vertically on said bearing and vertically and horizontally into the socket.
In testimony whereof I have hereunto set my hand at Grand Rapids, Michigan, this 5th day of May, 1931.
WILLIAM E. LARSON.
