Application June 9, 1942, =s eri 1 -K 446355 ',f" "6-Glaims. (cr es-M3756) I -This invention relates generally tothe class of chairs, and pertains particularly to improvements in means for securing chairs or seats to the floor or other suppflrt." y

The present invention is directed primarily to an improved means for securing in place the seats used in buses, train coaches or the like but may be readily employed in other locations, as in theaters or auditoriums, or for single or individual seats Wherever it is desirable that the same be fastened againsct unauthorized removal.

For the purpose of properly cleaning buses and train coaches or other places used by the public and where chairs or' seats must be providedand secured in position, itis very difficult to thoroughly clean the buses, coaches or othervplaces Without removing the seats. At the'present time the chairs or seats of buses and train coaches, airplanes, and other vehicles are secure'dto the floor by bolts and screws andwhen it is necessary'to remove and replace such seats, considera'ble time and labor is involved,it"being necessaryto employ the services of at least two men I 't'o'do the job. i

' The principal object 'of the present invention, in'view" of the foregoing, is 'toprovide an improved method or means of securing the seats or chairs used in buses, train coaches, airplanes or other structures, to the supporting floor in such a way that the securing means may be easilyand :We Qh-inehmesth e m s l-w qrm d quickly released or established'as necessary so that the removal or replacement of such seats may be accomplished'with' the'minimum of effort and 'very quickly. g I

Another object'of the invention is to Provide an aperture 18 .through which extends the a chairor seat securing,meansWhich-will firmly drawfthe'cliair down to solid engagement with" the supporting floor, and Which may bejeasily and quickly locked or unlocked as "desired, so that jarring and vibrationwill not result in the loosening of thelocking connection between the seat and the floor.

'Ihe invention will bebestunderstoodfrom a consideration of the following detailed descripconstituting the "present invention.

The lower part of the nut 2| is rounded upon the front and rear corners or edges So that a forced swinging of the hook and shank is facilitated against the holding action of the spring 23. g

The lower or fioor portion of the anchor unit comprises a bracket, indicated generally by the numeral 24, which has the bottom portion 25 and the spaced parallel upstanding or side portions or plates 26. The bottom portion 25 of the bracket is secured to the floor by a bolt 21, as shown, or by any other suitable means.

Extending across the space between and supported by the side portions 26 of the bracket 24 is a rock shaft 28 which, at one end, carries upon the outer side of the adjacent plate26 the head 29 of polygonal outline designed to be grasped by a wrench or other suitable tool. Between the plates 26 the rock shaft 28 carries a rigid tongue 30.

The bracket 24 is secured to the fioor between the pin receiving openings l4 in such postion that when the chair is put into place the bight portion of the hook 22 will be below and slightly rearwardly of the vertical plane in which the axis of the shaft 28 lies. Thus, when the rock shaft 28 is rotated 50 as to swingthe tongue 30 against theadjacent side of the shank 20, such tongue will move into the bottom of the bight of the hook and push down against the hook and cause the latter to swing under and to the opposite side of the axis of the shaft 28. The tongue 30 will thus exert a downward pull on the hook and at the same time oscillate the hook so as to bring the shank against the side of the shaft 28 and move the point of the hook bill under and beyond the other side of the shaft, thereby establishing an off-center strain between the hook and the end of the tongue.

At an elevation below the lowest part of the hook 22 and ofiset from the vertical plane in which the axis of the shaft 28 lies, there is supported between the side plates 26 of the bracket the latch bar 3| which carries a latching finger 32 which is designed to be brought into contact with the back of the book after the latter has been secured by the tongue 30 in the manner illustrated and described and form a wedge against the hook which prevents it from swinging back to its initial position and becoming disconnected from the locking tongue 33. One end of the bar 3| extends beyond the outer side of a plate 26 and joins an, end of an operating lever which has a short angular portion 33 and a longer handle portion 84, said portions being connected by vibration, jars or other means than the positive application of force to the shaft 28 to rock the same after the latch bar has been turned to remove the latching finger from position against the back of the hook.

I claim:

1. Means for coupling together two superposed bodies, comprising a hook having a relatively long shank, means pivotally coupling the end of the hook shank with the uppermost one of said bodies whereby the hook hangs downwardly therefrom, a bracket member secured to the lowermost one of the pair of bodies and having a pair of spaced upstanding side portions, the bracket being disposed beneath the hook, a shaft extending between and supported by the spaced portions of the bracket, transversely of iii angularly related so that when the longer por- 1 tion 34 is extending upwardly the shorter portion 33 will be extended down toward the floor and obliquely thereto. This operating portion or levermade up of the two parts 33-34 is forced between'an upstanding s'pring'tongue 35 and the the shank and at an elevation above the hook, a locking tongue carried by the shaft and adapted upon rotation of the shaft in one direction to swing downwardly toward the hook shank and into the hook to bear against the hook and exert longitudinal strain upon the shank, said tongue effecting the oscillation of the hook transversely of the shaft between the latter and the lowermost one of the bodies, said shank being longitudinally bowed to facilitate movement of the hook beneath and across the shaft, and means for securing the hook against reverse oscillation.

2. A coupling means as set forth in claim 1, in which the hook securing means comprises a bar rockably supported between the side members of the bracket and disposed at an elevation between the shaft and the lowermost member, and a finger carried by the bar and adapted upon oscillation of the bar in one direction to engage the hook upon the side thereof opposite from the shaft and tongue.

3. Means for securing a chair, seat or the like to a floor comprising a yoke member secured to the under side of the seat, a hook having a relatively long shank, means pivotally coupling the ends of the shank to the yoke, a bracket adapted to be secured to the floor beneath said yoke and having a pair of upstanding side members between which the hook positions, a shaft rotatably supported between said side members and across the shank of the hook in close proximity to the shank and between the hook and the yoke, a lc cking tongue carried by the shaft and adapted upon oscillation of the shaft in one direction to prove toward the shank and downwardly into the hoe-l: and engage the hook to exert longitudinal strain ,upon the shank, said hook shank being longitudinally bowed to facilitate the swinging of the hookacross and between the shaft and the fioorto'a position where the locking tongue is directed obliquely downwardly away from the hook shank.

4. A seat securing means as set forth in claim 3, including a locking means for the hook which comprises a bar rockably supported between the sidemembers of the bracket at an elevation between the shaft and the floor and to one side of the vertical plane of the shaft, and a finger carried. by the bar to be interposed between the bar and the hook upon the side of the hook remote from the shaft.

5. Means for securing to a supporting floor a chair, seat or the like having supporting legs and a rail connecting between the legs, comprising position locating pins carried at the lower ends of the legs for engagement in apertures in the floor, a bracket member secured to the floor between the legs and having'a pair of upstanding side portions, a yoke secured to said rail above the bracket member, a hook having an elongated shank, pivotal means connecting the upper end of the shank with theyoke whereby the hook hangs downwardly between said portions of the bracket, resilient means carried by the yoke and having operative connection with the hook shank for maintaining the shank yieldably in a predetermined position with respect to the bracket, a shaft rotatably supported between the side portions of the bracket and extending across the hook shank between the hook and the yoke, and a locking tongue carried by the shaft and adapted upon rotation of the shaft in one direction to enter the hook and exert longitudinal strain upon the shank and to swing the hook transversely across the shaft between the latter and extends obliquely downwardly away from the shank of the hook.

6. A chair or seat securing means as set forth in claim 5, including a bar rockably supported beby the bar and disposed between the bar and the hook to prevent swinging of the'hook away from the shaft when the bar rocking means is in said predetermined position.
