A telescoping support bar installed in a shower enclosure and similar facilities requires no mechanical wall fasteners. The support bar includes telescoping tubes with end retainers gripping walls of the enclosures. Length of the support bar is governed by fixed length spacer means and internal extensible means. Extensible means, having bearings movable along a rod, provides the lengthening and shortening of the support bar as the distance between the bearings is increased or decreased. This change in distance likewise changes the overall length of the support bar. With the retainers snug against the walls, one of the tubes, being rotatable, is turned in circular motion. This rotation is converted into an axial force along the bar causing the retainers to forcefully grip the walls, providing a rigid and strong bar installation.

We claim: 1. A telescoping wall-to-wall support bar for installation in enclosures such as a shower or bath and shower combination; said support bar comprising retaining means with sealing means, rotatable means, spacer means, extensible means, telescoping means, and covering means in combination forming a longitudinal rigid assembly:a) said retaining means comprising suction cups having a compressible, pliable material; and said sealing means engaging wall surfaces of one of said enclosures; said retaining means having a first retainer at one end of said telescoping support bar; said first retainer having a threaded stud mating with a threaded first bearing means of said rotatable means; and said retaining means having a second retainer at the opposite end of said telescoping support bar; said retainer means engaging the ends of the telescoping support bar to forcefully engage said wall surfaces of one of said enclosures; andb) said rotatable means comprising a first diameter tubular section circumferentially securing said threaded first bearing means; and having a longitudinal axis directionally oriented to receive a second diameter tubular section of said telescoping means to function as a telescoping unit; said rotatable means coupling with said retaining means through threads of said first bearing means mating with threads of said threaded stud of said first retainer; said first bearing means cooperating with said threaded stud of said first retainer to convert rotational motion of said first diameter tubular section into translational movement of said retaining means to generate compressive axial force traversing the longitudinal axis of said telescoping support bar and forcing said retaining means to engage said wall surfaces of one of said enclosures; andc) said spacer means being positioned in a spatial void between said first bearing means of said rotatable means and a third bearing means of said extensible means; said spacer means comprising a third tubular section circumventing and fixedly securing a plurality of second bearing means; one of said plurality of second bearing means providing passage for longitudinal projection of said threaded stud of said first retainer and a second one of said plurality of second bearing means providing passage for longitudinal projection of a rod of said extensible means; the ends of said third tubular section, in combination with said plurality of second bearing means, engaging surfaces of said first bearing means of said rotatable means and engaging surfaces of said third bearing means of said extensible means; andd) said extensible means comprising a plurality of said third bearing means encircling the longitudinal axis of said rod; said plurality of third bearing means having mobility along the longitudinal axis of said rod, said extensible means providing adjustability to the overall length of said telescoping support bar through movement of said plurality of third bearing means along the longitudinal axis of said rod; said extensible means comprising fastening means radically operable within said plurality of third bearing means to capture said rod and to lock said longitudinal movement of said plurality of third bearing means; ande) said telescoping means comprising a plurality of fourth bearing means, and said second diameter tublar section enclosing and fixedly securing said plurality of fourth bearing means; one of said plurality of fourth bearing means providing passage for longitudinal projection of said rod of said extensible means and a second one of said plurality of fourth bearing means providing passage for a stud of said second retainer of said retaining means; said second diameter tublar section having a radius smaller than the radius of said first diameter tubular section of said rotational means to permit said second diameter tubular section to axially translate in and out of the interior of said first diameter tubular section along the longitudinal axis of said telescoping support bar; andf) said covering means comprising a fourth tubular section adjacent said second retainer of said retaining means and directionally oriented with the longitudinal axis of said telescoping means; said fourth tubular section longitudinally encircling said second diameter tubular section; and said covering means comprising a plurality of sleeves; one of said plurality of sleeves circumventing said first retainer of said retaining means and an end of said first diameter tubular section adjacent said first retainer, and a second of said plurality of sleeves circumventing said second retainer of said retaining means and an end of said fourth tubular section adjacent said second retainer.
