7 Claims.

This invention relates to a leg attaching device designed primarily for use in connection with the legs of card tables, but it is to be understood that a leg attaching device, in accordance with this invention may be employed in any connection for which it may be found applicable, and the invention has for its object to provide, in a manner as hereinafter set forth, a device of the class referred to for setting up a wedging'action l0 uponthe leg when the latter, is extended and to detachably maintain the leg in such position.

A further object of the invention is to provide, in a manner as hereinafter set forth, a leg attaching device for pivotally connecting the leg with the table top and including spring controlled releasable means for fixedly securing the leg stationary when the latter is extended.

A further object ofthe invention is to provide, in amanner as hereinafter set forth, a leg attaching 1 device for pivotally connecting the leg with a table top, and including spring controlled releasable wedging means carriedby the leg for fixedly securing the latter in extended position.

Further objects of the inventionare to provide, in'a manneras hereinafter set forth, a device for the purpose referred to, which is simple in its construction and arrangement, strong, du-

rable, compact, readily installed with respect to a table top, thoroughly efiicient for the purpose in- 3 0 tended, and comparatively inexpensive to manufacture. I r r To the above ends essentially, and to others which may hereinafter appear; the invention consists of such parts, and such combination of parts which fallwithinthe scope of the invention as claimed. 1

In the drawing: 7 v r p Figure 1 is a fragmentary view in section of a table top showing the adaptationtherewith of 49 the leg attaching device in position formaintaining a leg extended, the device being shown in side elevation and the leg broken away. Figure2 is a fragmentary view insection of a tabletop showing the adaptation therewith of the leg attaching device in position for maintaining a leg extended, the device being shown in rear elevation and the leg broken away.

Figure 3 is a fragmentary view in inverted plan of a table top showing the adaptation therewith of the leg attaching device and with the leg in folded position, the devicebeing shown in inverted plan and the leg broken away.

The leg attaching device includes a channeled shaped housing 1 toreceive the upper portion of 5 .a table leg 2, and the width of the housing relative to that of the upper portion of the leg is such, that a wedging action will beset up between the sides of the housing and sides of the upper portion of the leg when the latter is extended. A wedging action is also set up between the upper portion of the sides of the leg and the sides of the housingwhen the leg is folded, but the area of such action is not as great when theleg is extended, and in this connection see Figure 3. The housing 1 includes a front wall 3 and a pair ofside

walls

4, 5. The length of the side walls is greater than the width of said front wall. The side walls are the same height and length and the height thereof corresponds to that of the front wall. The bottom edge"? of each side wall is of less length than the top edge 8. thereof. The end edge 9 of each side wall is extended rearwardly with respect-to the rear end of edge 7 and is rearwardly curved from edge 7 to edge 8. The sidewall 5 at its top is formed with a laterally extended lengthwise disposed apertured flange 10. Thewall 5 has a pair of spaced openings 11 for a purpose to be referred to. I I I One of the dependingends of table top 12 is indicated at 13. One of the depending sides of top 12 is designated 14. The top 12 is countersunk in theend and

side

13, 14 respectively as at 15, 16 respectively. The housing 1 is positioned below the top 12 in a manner whereby front wall3 will abut the inner face of end 13' and wall 4 will abut the inner face of side 14. Holdfast means 17 extend through wall 3 and engage in end 13. Holdfast means 18 extend through wall 4 and engage in side 14. I-Ioldfast 'means 19 extend through flange 10 and engage in top 12. The openings 10 in wall 5 permit of access being had to holdfast means 18. The

walls

4, 5 are provided with wedge shaped

notches

20, 21 respectively which. open at the rear ends of the bottom edges 7 of saidwalls. The inner transverse corners of leg 2 are rounded as at' 22, 23. Extended throu h the leg 2 in proximity to its inner or upper end'and at a point between its lengthwise median and rear side is a pivot bar 24 therefor'which extends through walls 4, 5' and is coupled to housing 1.- The ends of bar 24 are headed asat 25. The rear side 26 of leg 2 is formed centrally with a recess 27 extending lengthwise of the leg. The outer end of the recess is open, as at 28. Positioned against the rear side26 of leg 2 and slidable relatively to and lengthwise of the latter is a spring controlled latching member 29 for wedging engagement in the

notches

20, 21

for the purpose of maintaining the leg in ex tended position. The member 29 is formed of an intermediate part 30 and a pair of

end parts

31, 32. The part 30 is of less width and of greater length than part 32, the latter is of greater width and of less length than part 31. The part 31 is of greater length than part 30. The member 29 has a centrally disposed lengthwise slot-33 formed in a portion of parts'31, 32 and extending through part 30. The width of part 32 with respect to part 30 provides a pair of oppositely extending

protuberances

33, 34 for wedging engagement in the

notches

20, 21 and for riding against the end edges 9 of

walls

4, 5. The part 32 has extending outwardly from the free edge and at right angles thereto a flange 35 constituting a finger grip for shifting.

member 29 against the action of its controlling spring to be presently referred to. The part 31 has extending inwardly from its free edge and at right angles thereto an abutment 36 which slides in the recess 27. Mounted in the recess 27 and interposed between the inner end wall of the latter-and the abutment 36 is the controlling spring 3'7 for the member 29. The spring 37 permanently tends to shift the member 2- infla direction towards the inner end of the leg 2. The member 29 is slidably connected to leg 2. bya plurality of headed'retaining elements 38 which extend through slot 33 and are fixed to leg 2 in spaced relation to' the inner end wall of recess 27. 1

The table top 12 has its lower face in proximity to the edges 9 of

walls

4, 5 provided with a pocket 39 to receive the flange 35 when the leg is folded.

If the leg -2 be in the position shown in Figure 3, andit is desired to latch it in extended position, the leg is pulled outwardly carrying the latching member therewith and with the

protuberances

33, 34 riding against the edges 9 against the action of spring 37. When the protuberanc es arriveat the open ends of the

notches

20, 21 the spring 37 will act to pull the protuberances in the notches thereby positioning member 29 in latching position, and with a wedging action being set up between the protuberances and walls of the notches as well as a wedging action being formed between the upper portion of the leg and

walls

4, 5 of the housing. To release the leg, the member 29 is pulled in a direction to provide for the protuberances to clearthe notches and to be positioned against edges 9. The leg can then be moved to the position shown in Figure 3, and with spring 37 acting to maintain the leg in folded or non-extended position.
