This formation is received in close fit in the retention cavity to further prevent axial rotation of the handle

Description

BACKGROUND OF INVENTION:
-Field of the Invention The present invention relates to an improved shopping cart handle at-tachment which prevents axial rotation of the tubular handle member.
Description of Prior Art It is desirable to provide an attachment for the elongated tubular handle of the shopping cart whereby to prevent axial rotation thereof. With the advent of new uses of the handle to display advertising material, such as the name of the store where the shop-ping cart is used and to further identify the owner of the shopping cart, it is desirable that the handle not be rotatable whereby to displace and conceal this information which i5 usually provided in a small strip form which is usually located under a transparent sleeve provided over the handle member. Furthermore, it is now becoming customary to install locking devices ~on these handles whereby to interlock shopping carts when they are nested together in a group. These locking devices are usually interlocked with one another via a chain link associated with each lock and the handle is thus subjected to heavy torsion loads when a series of nested carts interconnected to one another are pulled.
` 25 This load is transferred on the handle member via ~:
the lock device causing the handle to rotate axially and thus rendering the locking device inoperable and further rotating or displacing the position of the advertisement strip makin~ it illegible.
SUMMARY OF INVENTION:
It is a feature of the present invention to provide a novel attachment means to permit leasy
- 2 ~

g;3 installation of the handle and prevent axial~rotation thereof.
Another feature of the present invention is to provide a novel handle construction for a shopping cart and wherein a lock pin format~ion is,formed at each end of a tubular member of the handle and~received in an arres.ting pas,sageway formed in an attachment portion of a respective handle support arm secured to the shopping cart.
Another feature of the present invention is,to pro.vide a novel handle attachment means and wherein the cross,-sect~ional configuration of the tubular member forming the handle cons;titutes,an arresting formation which is, received in a~retention cavity formed in the handle attach-ment portion of a res,pect~ive one of the handle support arms:
which are secured to-the shopping cart.
According to the above features;, from a broad as.pect, the present invention provides;a handle for a shop-ping cart~. The handle comprises;an elongated tubular member of s~uare cross.-section and having opposed securable ends:.
A pair of s~paced apart handle support arms is secured to the shopping cart for securement of the handle thereto.
Attachment means,is.provided in each of the ends of the tubular member and includes:a fas~tener element and arrest~ing means~preventing axial rota-tion of the tubular member. The arres.ti.ng means;comprises,the combination of a lock pin extension formed at~each of the ends;of t~he t~ubular member and extending outwardly thereof. A retention cavity is formed in a handle attachment portion of each of the handle s,upport arms;. The lock pin ex-tension is received in an arres*i.ng passageway of an attachment porti.on of an as.soci.a-ted handle s.upport arm. The retention cav~ty :i.s of

~3 BRIEF DES~RIPTION OF DRAWINGS:
A preferred embodiment of the present inven-tion will now be described with reference to the example thereof as illustrated by the accompanying drawings in which:-FIGURE 1 is a perspective view of a portion of -the rear wall of a shopping cart showing the handle construction;
FIGURE 2 is a partly fragmented perspective view of an end of the shopping cart handle of the present invention;
FIGURE 3 is a partly fragmented end view of the handle attachment portion of a handle support arm showing the retention cavity and the location of the lock pin formation;
FIGURE 4 is a fragmented end view of the handle attachment portion on the opposed side of Figure 3 and showlng the bolt head receiving cavity and the location of the lock pin formation in the arresting passageway; and FIGURE 5 is a cross-section view along cross section lines 5-5 of Figure 4 illustrating the manner in which the end of the handle of the present inven-: 25 tion is secured to -the handle attachment portion of a handle support arm.
: DES~RIPTION OF PREFERRED EMBODIMENTS:
Referring now to the drawings, and more particularly to Figure 1, there is shown generally at 10, the rear end portion of a shopping cart. An elongated tubular handle member 11 is secured spaced from the rear wall 12 of the shopping cart by a pair of handle support arms 13 which are formed from a wire member shaped to define a handle attach~ent por~
tion 14. The opposed ends of the handle 11 define securable ends which are secured to the handle attach-ment portion 1~, as will be described later.
As also shown in Figure 1, a locking device 15 is illustxated and secured centrally of the handle portion. These lock devices are used to interlock shopping carts when nested together. Whenever a secured shopping cart is displaced or pulled, the locking device 15 is given a jolt from its attachment end thereof and this jolt is transmitted to the handle 11 as a torsion load or force, causing the handle 11 to axially rotate. Also, these handles are usually provided with insert strips 16 to display some adver-tising words, such as 17, and this is usually aligned whereby it is visible by the person pushing the cart.
Accordingly, if the handle 11 was to be rotated axially, the wording 17 on the strip 16 may no longer be visible to the user, thus defeating the purpose of the adverti-sing strip. The handle attachment of the present inven-tion prevents this axial rotation of the handle.
Referring to Figure 2, there is shown the arresting means or lock pin formation 18 which is formed integral with an elongated tubular member 19 which is a hollow metal tube of substantially square cross-section. The lock pin is a right-angled corner extension of the tube and thus the angle formed pro~
vides structural rigidity. Such a lock pin for~lat:ion 18 is formed in opposed ends of the handle. Also, as hereinshown, the handle comprises the usual tubular sleeve 20 having at least a portion 21 thereof farmed of transparent material and oriented such as to be aligned wi-th the plastic strip slidingly disposed over the flat wall 19' of the tube 19 under the tubular sleeve 20 whereby the wording 17 is visible through the transparent portion 21. The sleeve 1]. is also provided with opposed ribs 11' to prevent the sleeve from rotating about the tubular member 19.
Referring now additionally to Figures 3 to 5, there is shown, in enlarged view, the construc-tion of the handle attachment portion 14 of the handle support arms 13. As hereinshown, the attachment por-tion is provided by a U-shaped bend 22 which defines a trough 23 between opposed wire portions 13' and 13" and defining therebetween an arresting passageway 24 whereby to receive the lock pin formation 18 in substantially close fit therein whereby to prevent axial rotation of the metal tubular member 19 and accordingly the handle 11 due to the abutment faces presented by opposed wire portions 13' and 13" main-taining the lock pin formation 1~ captive therebetween in the passageway 24.
A fastener element 25 (see Figure 5) is provided whereby to secure each opposed end of the ; tubular member 19 to the handle attachment portion 1~ of a respective one of the handle support arms 130 The fastener element 25 comprises a threaded nut 26 retained captive between opposed flat walls 19' of the tubular member 19 adjacent a respective end 27 thereof. The nut 26 is retained in position ~L2~ 3 by indentations 28 formed in the metal tube 19 on opposite sides of the nut 26 and in opposite walls 19'. The fastener element also comprises a bolt 28 having a threaded shaft portion 29 for engagement with the nut 26 and a head 30.
In order to further prevent axial rotation of the handle 11, there is provided in combination with the lock pin formation 18 an arresting formation in each of the securable ends of the tubular member 19 and constituted by the cross-sectional configuration of the tubular member 19. This arresting formation is nestable within a retention cavity 31 which is stamped or otherwise formed in a respective one o~
the handle attachment portions 14. This retention .15 cavity is configured as a substantially square cavity to receive a major portion of the square end wall 27 of the tubular member 19 therein. The fastener ~:~ element 25 is disposed axially of the tubular member 19, as shown in Figure 5, and retains the end wall 27 of the tubular member under tension against the flat wall 31' of the retention cavity 31. As shown ; in Figure 3, thë lock pin formation 18 extends through the passageway 24 and also facilitates assembly making sure the strip 16 is always properly positioned. The tubular member is arrested from axial rotation by both the retention cavity 31 and the lock pln formation 1~ .
As shown in Figures 4 and 5, the handle attachment portion 14 is further provided with another cavity 32 formed on the opposite side of the retention cavity 31 and in substantial alignment therewith~
This other cavity 32 is deeper than the retent:ion cavity 31 whereby to conceal a substantial portion ~L2~3 of the bolt head 30 therein to conceal any jagged edge of the head. A lock washer (not shown) could also be provided under this bolt head 30. The other cavity 32 also has a flat wall 32' for the bolt head 30 to rest flush thereon.
It is within the ambit of the present inven-tion to provide any obvious modifications of the ex-ample of the preferred embodiment described herein, provided such modifications fall within the scope of the appended claims.
