Abstract
A commode is disclosed having a specially configured bolts to secure the commode seat to the frame of the commode. The bolts are affixed to a back bar of the commode frame and have a straight portion adapted to be secured to the back bar and an angled portion to be secured pivotally to the rear of the commode seat. The straight portion and the angled portion are formed together with an intermediate arcuate portion to form an acute angle with respect to each other. In the assembled commode, the straight portion of the bolts extends horizontally rearwardly from the back bar so as to avoid damage to a household toilet when the commode is positioned atop the toilet. In addition, by the special configuration, the rear of the commode seat is positioned vertical directly above the back bar to prevent the commode seat from falling any appreciable distance downwardly in the event of a failure of one or both of the special bolts.
Description




FIELD OF THE INVENTION




The present invention relates generally to the mounting of the frame of a commode seat to a commode or like seating device, and, more particularly, to a pair of mirror image bolts that are fastened to the commode or seating device so as to have a portion that extends generally horizontally rearwardly from the point of attachment to the rear frame member of the commode, an angled straight portion and an intermediate arcuate portion, the angled straight portion and the straight portion forming an acute angle with respect to each other.




BACKGROUND OF THE INVENTION




Typically, commodes are regularly used by elderly or infirmed persons to aid in the convenience of use by such persons that cannot use, or for some reason find it difficult to use, the normal porcelain toilet commonly used in households today. By definition, the use of the word commode and toilet are sometimes used interchangeably for both of the devices and thus, in order to provide clarity, the use of the words hereinafter in the present description will be to use the term commode to describe the present device that is portable and movable to aid the person and the term toilet will be used to describe the typical porcelain device that is of the standard household variety.




With the use of commodes, there are at least two somewhat independent uses. One is where the commode is serving as an independent device and is interfitted with a pail having a solid bottom to catch and retain the waste products at any convenient location to the user, such as bedside. Such commodes are generally comprised of a relatively light frame, normally of a metal tubular construction, and are easily movable to desired locations and may even include wheels that are lockable into a fixed position to allow the device to be rolled along the floor to the location of choice. An alternate use, however, of the commode is to move or otherwise position the device to be located physically over the standard toilet so that, in effect, the user has the convenience and comfort of the commode configuration but uses the standard toilet for the disposal of the waste products. In the latter use, obviously, the pail has no bottom and operates more in the form of a splash guard to direct the waste products into that standard toilet.




One disadvantage in the latter use of a commode is in the location of the bolts that fasten the commode seat assembly to the frame. The seat assembly normally includes a seat on which the person is situated and a cover overlying that seat and covering the underneath components when the commode is not in use. Both the seat and the cover are conventionally pivotally affixed with respect to the frame to enable the user to individually lift the cover into its usable and non-usable positions and to also raise the seat for access to the pail for disposal of the waste products or for removal of the pail or splash guard for cleaning. As such, the securing bolts are normally affixed in some manner to the commode seat to allow that pivoting movement and securely affixed to one of the frame members of the commode, preferably a back bar as will be explained. The bolts are conventionally affixed to the back bar or other frame member by passing the threaded ends of such bolts vertically downwardly through the frame member and securing the bolts to that frame member by affixing nuts to the threaded ends to be tightened and complete the assembly.




The difficult arises, therefore, in the positioning of the vertically oriented threaded ends into the frame the member. When assembled, the lower ends of the threaded bolts project through the nuts for a finite distance and those bolt ends thus project outwardly of the nuts in a downward vertical direction. When the commode is used over the standard porcelain toilet, therefore, the lower ends of the bolts can cause considerable damage to the porcelain finish of the toilet and which is certainly an undesirable situation. Since the commode, as indicated, is used over the standard household toilet, damage to the porcelain can permanently affect the look of the toilet and the physical damage not readily repairable.




Accordingly, it would be desirable to provide de differing orientation and positioning of the bolts that secure the seat to the commode so as to not cause permanent damage to the porcelain toilet in the household.




As a further problem with commodes, the rear of the commode seat is supported above the back bar by bolts but the rear of the seat is normally situated inwardly disposed with respect to the back bar and thus, in the event of a failure of the rear support bolts, the seat can collapse downwardly and will not be restrained from full downward movement by that back bar. Thus, the seat is capable of collapsing downwardly with the person positioned on the seat.




It would thus also be desirable to provide a system where the bolts not only hold the rear of the seat firmly in position, but position the rear of the seat directly vertically above and in alignment with the back bar support such that, in the event of a failure of one or both of the bolts, the rear of the seat will fall downwardly only a slight distance and then be fully supported and prevented from further downward movement by that strong support of the back bar.




SUMMARY OF THE INVENTION




Therefore, in accordance with the present invention, a commode construction is provided that overcomes the difficulties and problems of the aforedescribed commodes and which has a frame on which the person can be situated with the frame having a front to which the person faces and a rear facing the back of the person. The frame is preferably of a tubular construction and includes a support member or back bar at the rear of the frame to provide support and is a structural member of the frame. A pair of specially constructed bolts are used to secure the commode seat to the frame and each bolt is a mirror image of the other. The bolts each have a generally straight portion having a threaded end that is inserted through the back bar and that straight portion, when so inserted, extends horizontally rearwardly from the back bar so as to prevent any damage to a porcelain toilet when the commode is positioned atop the toilet. The bolts are shaped so as to form an angled straight portion with an intermediate arcuate portion between the straight portion and the angled straight portion. The arcuate portion configures a curving shape that leads into the upward angle and forward direction to the angled straight portion.




The angled straight portion terminates in upper ends that are shaped so as to interfit with the seat and to allow that seat to pivot with respect to the fame. In the preferred embodiment, the upper ends that interfit with the commode seat are formed at an angle from the angled straight portion and more preferred, the straight portion the arcuate portion and the angled straight portion are in a common plane that is vertically oriented and the upper ends are formed at about a 90 degree angle with respect to that plane. Thus, in the preferred embodiment, the upper ends of the angled straight portion can simply be inserted into horizontally disposed bores in the seat itself to support the seat to the frame. Since the bolts are mirror images of each other, they can be used with a commode seat where the upper ends are inserted into the bores outwardly with respect to the seat or, by reversed the bolts, they can be used in an orientation where the ends of the arcuate portion are inserted inwardly into the bores in the seat.




By the particular curvature and the vertical height of the bolts of the present invention, the rear of the seat can be positioned directly vertically above the back bar and be oriented so that, in the event either or both of the bolts fail, the rear of the seat will only fall a short distance whereupon the rear of the seat will hit upon and be supported by the back bar. Thus, in the event of such failure, the person only moves downwardly a slight amount, possibly an uncomfortable but safe distance.




Other features and advantage will become apparent to those skilled in the art from a review of the ensuing description while proceeds with reference to the following illustrative drawings.

DETAILED DESCRIPTION




Referring now to

FIG. 1

, there is shown a perspective view of a commode


10


constructed in accordance with the present invention. As can be seen, commode


10


comprises a pair of inverted U-shaped side frame members


12


that are spaced apart to provide a seating space for the user therebetween in utilizing the commode


10


. As used herein, by convention, the front of the commode


10


will be referred to as the direction the user is facing when seated in the commode


10


and thus, in

FIG. 1

, the frame members


12


are shaped so as to include front legs


14


and rear legs


16


, each of which may have flexible cups


18


attached to the bottom of such legs to prevent the commode


10


from slipping on the floor or to form deep indentations in a carpet. Each of the front legs


14


and the rear legs


16


may also include some adjusting mechanism


20


as is conventional to allow the telescoping legs to be extended or retracted to adjust the commode


10


to the desired height from the floor to be convenient to the user.




As also can be seen, there is a front bar


22


and a back bar


24


, in accordance with the defined convention, to provide support for the overall frame assembly for rigidity and integrity of the commode


10


. The back bar


24


may be part of a U-shaped back member


26


and which can also provide a means of positioning a back support


28


that supports the back of the user during use of the commode


10


.




A further pair of bars


30


(only one of which is shown in the Figure), also adds to the structural integrity of the commode


10


by connecting the front bar


22


and the back bar


24


. A commode seat


32


is affixed to the frame and, as shown, the commode seat


32


is supported by the back bar


24


in a manner that will be later explained. It is to sufficient to note that the commode seat


32


is pivotally mounted with respect to the frame so that it can be raised and lowered by the user. As shown, it is in its lowered position. Atop the commode seat


32


, there is positioned a cover


34


that is also pivotally affixed with respect to the frame and to the commode seat


32


so that the commode seat


32


and the cover


34


can be independent raised and lowered by the user.




As can be seen in

FIG. 1

, two specially constructed bolts


36


are used to affix the commode seat


32


to the back bar


24


and, although the embodiment utilizes two of such bolts, in some fairly rare instances, more than two bolts


36


could be used in the commode


10


to secure to the commode seat


32


to the back bar


24


.




Turning now to

FIGS. 2 and 2B

, taken in connection with

FIG. 1

, there is shown perspective views of the bolts


36


that are the essence of the present invention and are specially formed to carry out the purposes hereof. As shown, the bolts


36


are mirror images of each other and therefore the description of only one of the bolts


36


will be sufficient to fully set forth the invention. Thus, in

FIG. 2A

, the bolt


36


includes a straight portion


38


that, in the assembled condition, extends rearwardly and horizontally from the back bar


24


. The forward part of the straight portion


38


has a threaded end


40


, the purpose of which will be late explained. Located rearwardly of the straight portion


38


is an arcuate portion


42


that is configured as a bend that again turns forwardly into an angled straight portion


44


. As can be seen, the angled straight portion


44


forms an angle with the straight portion


38


and preferably that angle is an acute angle shown as the angle A and, more preferably, the angle A is about 40 degrees. In the preferred embodiment, the straight portion


38


, the arcuate portion


42


and the angled straight portion


44


are all in a common plane, and when installed as in

FIG. 1

, that plane is preferably a vertical plane.




At the uppermost part of the angled straight portion


44


there is an upper end


46


that is adapted to be affixed to the commode seat


32


in a manner that allows the commode seat


32


to pivot about that upper end


46


. Again, in the preferred embodiment, where the straight portion


38


, the arcuate portion, and the angled straight portion


44


of bolt


36


are all in a common plane, vertically disposed when assembled, the upper end


46


extends outwardly at a right angle to that plane, thus the upper end


46


, when assembled, extend generally horizontally.




Turning now to

FIG. 3

, there is shown a side view, partly in cross section, showing the commode seat


32


supported by the back bar


24


by means of bolt


36


configured in accordance with the present invention. As can be seen, therefore, the back bar


24


is a cylindrical tube, preferably of a rigid metal construction, and has two similar sized holes


48


,


50


drilled horizontally through the back bar


24


. Thus, in securing the bolt


36


to the back bar


24


, the straight portion


38


is inserted forwardly through the two holes


48


,


50


and a nut


52


is secured to the threaded end


40


to firmly secure that bolt


36


to the back bar


24


. The arcuate portion


42


thus abuts against the upper edge of the rear hole


48


and prevents the straight portion


38


from further entering the back bar


24


so that the tightening of the nut


52


can hold the bolt


36


in its position as shown.




To affix the upper end


46


of the bolts


36


to the commode seat, the upper ends


46


are slipped into bores


54


formed laterally in the commode seat


32


. Thus, the commode seat


32


can be pivoted about the upper ends


46


by the interfitting of the upper ends


46


within the bores


54


so that the commode seat can be raised and lowered to the desired position.




Thus, the commode seat


32


is held to the back bar


24


and is vertically positioned above that back bar


24


. In

FIG. 3

, it can be seen that by the particular configuration of the bolts


36


the rear end of the commode seat


32


can extend to be vertically directly above the back bar


24


and, accordingly, in the event of a failure of either or both of the bolts


36


, the commode seat


32


can only drop a small amount before it hits the back bar


24


and is thereafter fully supported by that back bar


24


. Therefore, even in the event of such failure, the user experiences only a slight drop in the commode seat


32


and suffers only a minor inconvenience.




Turning, finally to

FIGS. 4A and 4B

, there is shown a rear view of the commode seat


32


in its assembled position to the back bar


24


. In the

FIG. 4A

embodiment, the bolts


36


are assembled such that the upper ends enter outwardly into the bores


54


in the commode seat. In the embodiment of

FIG. 4B

, the same bolts


36


, having been reversed, can now interfit inwardly into the bores


54


in the commode seat


32


. Thus, the same bolts


36


by reversing their positions, can be used interchangeably where the bores


54


in the commode seat are directed outwardly or inwardly without modifications or changes to the bolts


36


.
