Sept. 24, 1957 c. ARMSTRONG ADJUSTABLE HANDLE GRIP Filed June 18, 1956 INVETOR. BY Charles Armstrong.
United States This invention relates to facilities widely and diversely employable in secure removable and replaceable attachment to items and fixtures of various kinds and types to function therewith as a handheld convenient of human grip, and more particularly to a handle attachment ex-' pediently applicable to conventional bathtub installations as a hand grip of convenient availability to users of the so-equipped tub, and has as an object to provide a novel and improved construction and organization of elements constituting a handle grip attachment of high practical utility.
A further object of the invention is to provide a novel and improved handle grip unit adjustably adaptable to operative association with bathtub wall members,,or analogous elements, of differing dimensions.
A further object of the invention is to provide a novel and improved handle grip unit adapted for convenient, detachable, operative association with a bathtub wall member, or analogous element, without alteration of or damage to the associated member or element.
A further object of the invention is to provide a novel and improved handle grip unit mountable in or removable from its position of use through the agency of simple, commonly-available tools.
A further object of the invention is to provide a novel and improved handle grip unit expedient of economical production in any desired size range, simple of secure attachment in position of practical use, of wide utility, and positive and eflicient in attainment of the ends for which designed throughout a long useful life.
With the foregoing and other objects in view, my invention consists in the construction, arrangement, and operative combination of elements as hereinafter set forth, pointed out in my claims, and illustrated by the accompanying drawing, in which I Figure 1 is an exterior elevation of an end portion of a conventional bathtub as equipped with a typical embodiment of the invention in position of use thereon.
Figure 2 is a top plan view of the organization according to Figure 1.
Figure 3 is a cross section through the tub as illustrated, taken substantially on the indicated line 3-3 of Figure 2.
Figure 4 is a section, on a relatively enlarged scale, through the improvement of the invention separated from the mounted association represented by the preceding views and taken substantially on the indicated line 44 of Figure 3.
Figure 5 is a transverse section through the improvement on the same scale as and taken substantially on the indicated line 55 of Figure 4.
The utility and practicality of handle grip units adjustably adaptable for detachable association with both fixed and movable members and elements are so apparent as to preclude occasion for elaboration. The importance of some such grip as an aid to bathtub users has long been recognized as evidenced by the provision of grips formed integrally with the tub or as accessories atent 2 adapted for attachment to wall areas adjacent the tub installation. However adequate may be the grips heretofore available for association with bathtubs, a condition apparently unsatisfied thereby is presented by a very large number of tubs lacking integral grips so installed as' to preclude practical association therewith of wall-mounted grips, which tubs are commonly characterized by smooth, imperforate upper margins terminating side walls of differing thicknesses, hence the instant invention is directed to the provision of a handle grip attachment adjustable for coaction with 'a considerable range of tub wall thicknesses and adapted for secure, detachable association with the tub in any selected disposition along the upper rim thereof without alteration of or damage to the tub structure.
As typified 'by the views of the drawing, a U-shaped frame adjustable as to Width of opening is comprised from complementary, expediently identicahninety degree angle plates 10and 11 opposedly paired in a slidably overlapped relation of corresponding web portions to register their other web portions in spaced parallelism. The angle plates 10 and 11 are formed from any suitable substantially rigid material, such as sheet metal, to a size and in a strength appropriate to meet the use requirements in contemplation, and in constructions adapted for coaction with rims of conventional bathtubs it has been found to be practical to provide said plates in a width parallel to the line of the angle bend somewhat greater than the width of an adult human hand and to form said plates with slidably coacting web portions 10 and 11', respectively, outstanding perpendicularly from relatively longer web portions 10" and 11", respectively, a distance conditioning each thereof to span transversely of and substantially across a conventional bathtub rim of minimum thickness. The overlapped web portions 10 and 11' of the angle plates are slidably interrelated for selective adjustment of the spacing between the parallel web portions 10" and 11" by means of elongated slots 12 intersecting the uppermost of said overlapped web portions, illustrated as the Web portion 10, inwardlyadjacent and parallel to the side margins thereof and bolts 13, or the equivalent, engaged with and perpendicularly through the underlying web portion 11 inwardly adjacent the free end margin thereof in extension through said slots in coaction with nuts 14 clampable against the exposed surface areas of the web portion 10 marginally of said slots. Thus, loosening of the nuts 14 permits slidable shift of the web portions 10' and 11 relative to each other for variation in the spacing between the web portions 10" and 11 within the range provided by the length of the slots 12, and tightening of said nuts serves to hold the said web portions 10 and 11' securely interclamped in a relation retentive of the adjusted spacing established between the associated web portions 10" and 11".
The U-shaped frame constituted from the angle plates 10 and 11 as above described mounts a handle or grip member parallel to and spaced outwardly from the overlapped web portions 10' and 11 in a manner supplementing the clamping action of the bolts 13 and their nuts 14. The handle or grip member includes a straight, rigid, preferably hollow element 15 sized and conformed as may be desired for coaction with the human hand in a length approximating the width dimension of the angle plates, legs 16 fixed to and similarly projecting from the opposite ends of said element 15 perpendicular to the length of the latter, and terminal flanges 17 inturned at the ends of said legs 16 to parallel and to underlie adjacent end portions of the element 15 in spaced relation therewith. The flanges 17 are adapted to seat against the exposed surface of the web portion 10' at the opposite sides of the latter when the associated legs 16 are registered with the side margins of the web portion and said wi-alikeinzalength such as to span transversely terms the adjacent slot 12 when said legs are so disposed.
