SWIlVIMlNG POOL LAMP FRAME LOCK Kurt Ritter, Campbell, Calif.

Application. October 28, 1957, Serial No. 692,595

6 Claims. (Cl. 240-46) This invention relates to lens frames for lamps and more particularly to a lock for such frames and fixtures associated therewith.

' The. embodiment of the present invention is-most suited for swimming pool' lighting fixtures or the like adapted tobe built into. the wall of a pool below the water level therein. It is a principal object of the invention to provide a simple yet effective locking means between a lens frame and the fixture in such. a manner as to enable removal of the lens when. the light globe is to be removed and replaced.

Heretofore much difficulty was encountered in. place: ment of swimming pool light fixtures and in the securing thereof in a manner facilitating ready removal thereof for repairs.

The present invention contemplates the provision of a novel locking means between a mounting frame on the pool Wall and a lens frame on the light fixture itself. The object here is to provide a simple yet effective locking means by which the fixture cannot be pulled out or re moved by children or swimmers, yet with the use of a simple tool the locking means can be disconnected to free the fixture for removal.

, Swimming pool lights are usually'a waterproof, unit adapted. to be submerged and inserted into arecess in the wall of the pool to water cool the fixture- Another object is to provide, in a two part lens frame structure a novelinterlocking means employing yieldableresilient means for maintaining, the interlocking features inilocking engagement with each other unless or until an outside force is applied. in a particular manner to release the same.

More. specifically the invention entails the provision of a stationary frame having an opening intowhich alens must be placed and aremovable. lens frame adapted to fit the opening in the stationary frame together with diametrically opposed locking tabs and bolts affording quick connection. and/or disconnection ofone from the other.

Thesev and other objectsand advantagesof the present invention will become apparent from a. reading of the following description in the light of the accompanying drawings in which: 1

Fig. 1 is an exploded perspective view of the two principal parts of the. lamp structure embodying the present invention.

Fig. 2. is a sectional detail view showing the two. parts of Fig. l in relation to each other.

Fig. 3 is an enlarged foreshortened: detail section of the, parts-of Figs. 1 and 2. in locked relation to each other.

Fig. 4: is. a vertical section. of Fig. 3 taken along line 4=-4 thereof showing the locking means in. elevation'from the inner side of the assembly.

As best illustrated in Figs 2 and 3, the present invention is. embodied in two main pieces and 11. Onepiece 10 is. adapted to be secured to a permanent structure whereas the piece 11 is movable relative to the first piece.

The two pieces 10 and 11 are each of annular shape, the part 10 being so configurated as to receive a portion of the part 11. In the specific embodiment of the drawing piece 10 consists of a mounting flange adaptedto be embedded in. cement mixture during the pouring thereof so as to become anchored and firmly secured in the resulting concrete 12 to form a framearound an opening 0. This opening 0 is so formed as to provide a mouth for a recess R in the concrete 12 for the reception of a lighting fixture F. I

The lighting fixture which may be of any well known design consists of a water tight shell H housing a socket S for receiving a light globe G. Waterproof, connections and conduits of the flexible type connected to the socket S. convey electrical current thereto from a power line, not shown, under the control of a switch, likewise not shown.

The fore or open end of the shell H is secured to the piece 11 in such a manner as to become movable therewith. To this end the piece 11 comprises an annular frame. for a lens 16 coveringv the open end of the shell H. Suitable seals 17 and 18 are provided between the flange 19 of the shell and a flange 2t) on the frame piece 11 to prevent water from entering the shell housing H.

The mounting flange piece 10 is preferably of L shape in cross section, the leg 21 of the piece 10 forming a cylindrical portion and the foot 22 of the piece 10 constituting an inner flange, the heel or outer portion 23 of which be comes, embedded. or anchored in the concrete 12. The extreme end-or outer face 24 of the leg21 is disposed flush with. the face 25. of the pool wall, i.e., the concrete. 12. As seen in Fig, 3, this wall may be faced with tile if desired in which case the leg 21 extends beyond: the rought concrete a distance to compensate for the thickness of the tile and the mastic by which it adheres. to the concrete 12.

The lens frame piece 11 consists, of an outer fascia 26 the outer-diameter of which is comparable to: the diameter of the cylindrical portion of the mounting flange 10, so as to overlie the extreme end or outer face 24 of the leg 21 which constitutesthe cylindrical portionof the mount ing flange.

The inner extremity of this fascia 26 is the flange 20. herein previously mentioned. This flange 20 forms an opening comparable in diameter to the open. outer end of the shell housing H of the fixture F. This inner extremity of the lens frame 11 is the fiange 20 against which the lens 16 is pressed.

The lens frame piece 11 is substantially of T shape in cross section, the fascia 26 forming the cap of the T shape while the leg portion 28 thereof extends inwardly (see Fig. 1 toward the fixtureF a depth. sufficient to receive the lens 16 and the two sealing rings 17 and 18, previously mentioned. 2

As best seen. in Fig.v 3. thesealingring 17 lies against the flange 20, the lens 16 having its outer extremity overlying the ring 17 itself being overlaid by the sealing ring 18. As illustrated Fig. 3 the flange 19 at the open end of the shell H is embeddedin the sealing ring 18= and the latter is pressed toward the lens 16- by a securing ri'ng'29.

The securing. ring 29 has an inner diameter such as to fit over the shell H from its inner endand to circumscribe theshell adjacent its flange '19. This ring 29 extends beyond the base end 30 ofthe. leg portion 28' of the T shaped lens: frame piece 11. The ring 29 also has a plurality of cars 31. at spaced intervals around its perimeter to overlie bosses 32 similarly spaced around the'cylindrical face of the leg portion 28 of the frame piece 11. The cars 31 are bored to receive headed machine screws 33- and the bosses 32 are bored and tapped to receive the the screws 33 into the tapped bores of bosses 32 the ring 29 is pressed firmly against the sealing ring 19. In this manner the lens 16 is likewise pressed against the sealing ring 18 and the sealings rings being preferably of rubber are compressed so as to establish a good water tight seal.

Having thus described the environment of the present invention the following is a clear and concise description of the salient features upon which invention is predicated. The invention herein resides in a locking means for the two part lens frame 11 and mounting 10 previously explained.

The locking means of the present invention comprises diametrically opposed keepers 35 and 36 each having component parts thereof on the mounting flange 10 and lens frame 11 respectively.

The keepers 35 and 36 are preferably arranged one above the other to facilitate ease of handling and assembly of the two parts to be joined. The keeper 35, which is lowermost, comprises a dovetail socket 37 provided in an enlarged projection 38 formed beneath the leg portion 28 of the T shaped cross section of the lens frame 11. This socket 37 is open on its lower surface to receive a wedge shaped rubber member 39 which becomes suitably anchored Within the dovetail socket by reason of the spread end 40 of the rubber member 39 being compressed into the same. The rubber member 39 has its narrower end 41 extended slightly from the projection 38 so as to bear against a detent 42 formed integrally with the mounting flange 10 at a position to meet the rubber member 39. As best seen in Fig. 1 the detent 42 is preferably a projection up from the leg portion 21 of the L cross sectioned mounting flange 10. This projection terminates in an apex which is approximately the width of the rubber member so as to present a chordal ridge 43 adapted to press into the yieldable rubber member 39.

The keeper 36, which is uppermost, comprises a bolt-like extension 46 on the upper outer side of the leg portion 28 of the T shaped frame member 11. This bolt extension 46 has a notch 47 formed on its upper surface so as to receive a strike plate or extension 48 formed integrally with the leg portion 21 of the L shaped mounting flange 10.

As best illustrated in Fig. 3, the strike plate 48 is wedge shaped in cross section, i.e., along the diametric plane in which the two keepers 35 and 36 are disposed. The strike plate extension 48 is narrowest at its point of juncture with the outer face 24 of the mounting flange 10. The plate 48 increases in depth inwardly of the leg member 21 to provide a cam surface 49 as well as an abutment edge 50 on the same. The abutment edge 50 is adapted to engage behind the fore end 51 of the bolt 46 formed on the lens frame 11. This fore end 51 of the bolt 46 has a cam shaped upper surface 52 comparable to the cam surface 49 formed on the strike plate. Thus it will be seen that the fore end 51 of the bolt member 46 also presents an abutment edge 53 inside the notch 47 for engaging the abutment edge 50 behind the strike plate 48.

The combined action of the two diametrically opposed keepers 35 and 36 is as follows:

Referring to Fig. 2 note that the lens frame 11 is held in such a maner as to dispose the fixture F within the recess or chamber R formed in the concrete 12. The frame 11 is held on a slant with the rubber member 39 resting upon the ridge 43 of the detent 42. The frame 11 is then rocked (clockwise Fig. 2) toward the mounting flange 10 whereupon the cam surface 52 of the bolt 46 will contact the cam surface 49 on the strike plate 48.

It should here be noted that the distance between the extended narrow end 41 of the rubber member 39 and the cam surface 52 on the bolt 46 is slightly greater than the distance between the ridge 43 of the detent 42 and the cam surface 49 on the strike plate 48. Consequently, the upper end of the lens frame 11 must be pushed against the mounting flange 10 with considerable force. When this is done the cam 49 on the stationary strike plate 48 forces the whole lens frame 11 downwardly causing the ridge 43 of the detent 42 to compress the rubber member 39. During compression of the rubber member 39 by the stationary detent 42 the frame 11 is still moving toward the mounting flange 10 (clockwise Fig. 2). However, as soon as the fore end 51 of the bolt 46 passes the strike plate 48 the rubber member 39 will expand to lift or force the entire frame 11 upwardly relative to the mounting flange whereupon the fore end 51 of the bolt 46 will be lodged behind the strike plate 48. Thus the abutment edge 53 on the fore end 51 of the bolt 46 engages the abutment edge 50 on the inner end of the strike plate 48.

In the foregoing manner the lens frame with fixture attached is firmly held by the mounting flange. It should here be noted that the flange 20 on the lens frame 11 does not afford a water tight seal against the outer face 24 of the mounting flange 10. Since the shell housing H is waterproof and a water tight seal is afforded at the open end of the fixture F the entire lighting unit within shell H, although below the water level, is isolated from the water. Consequently, although water may enter the recess or chamber R, since the shell H is water tight and all wires are of a waterproof character no contact of water with electrical conductors or units can occur.

Should replacement of a bulb be necessary it is a simple operation to remove the fixture from the mounting flange and recess. Note that the outer face 24 of the leg portion 21 of the mounting flange 10 has a cut away or gap 60 formed therein adjacent the strike plate 48. This is clearly shown in Fig. 1. In Fig. 3 the gap 60 leaves a crevice between the flange 20 of the lens frame 11 and the mounting flange 10. This crevice at gap 60 admits entrance of the tip of a screw driver or any other suitable flat tipped tool or bar. Such tool being rigid can be pressed down upon the bolt 46 to again press the rubber member 39 down upon the ridge 43 of the detent 42. The moment the abutment edge 53 on the fore end 51 of the bolt 46 is forced below the abutment edge 50 on the inner end of the strike plate 48 the lens frame 11 will be spread away from the mounting flange 10. This spreading or movement of the upper end of the frame 11 away from the mounting flange can be effected by a manual rocking or prying action of the tool or screw driver, previously mentioned. The lens frame 11 is thereby rocked away from the mounting flange 10 (counterclockwise Figs. 2 and 3). In either case, whether connecting or disconnecting the lens frame relative to the mounting flange, the ridge 43 of the detent 42 serves as a fulcrum about which the frame 11 rocks either toward or from the mounting flange 10.

Having thus described the lock for swimming pool lamps in specific detail it will be appreciated that the same may be altered, varied and/ or modified without departure from the spirit of my invention. I therefore desire to avail myself of all modifications, variations and/or alterations as fairly come within the purview of the ap pended claims.
