Abstract

ABSTRACT OF THE DISCLOSURE:

An anti-theft bicycle rack has a hollow base member with a pair of spaced holes through its top wall.
The lower ends of upright locking arms extend through these holes into the hollow base where they are mounted for pivotal movement between an outwardly inclined release position and an upright lock position. The pivot mechanism is wholly within the base member and cannot be reached through the top wall spaced holes which are only large enough to allow for pivotal movement of the locking arms. The pivot mechanism includes lock bolts that project into the ground and are cast into a concrete mass so that the base member may not be removed. The upper ends of the locking arms each has a horizontal bicycle engaging bar having locking pins projecting, in locking position of the arms, between the wire spokes of a bicycle wheels.
Finally, locking tabs are provided at the upper ends of the locking arms, overlapping one another in lock position of the arms, and having registering holes for the insertion of a shackle of a padlock.

Description

BACKGROUN~ OF THE INVENTION

FIELD OF THE INVENTION
The present invention relates to an anti-theft bicycle parking rack.

A multitude of bicycle storage or parking racks have been proposed and are presently used, being designed mostly to avoid or discourage thefts. Ingenious devices have been invented for that purpose but most are inefficient and even with the best of padlocks, skilled thieves manage successfully to unlock or break them to remove the bicycle. Where the padlocks and racks are of a more sophisticated type and better resist attempts at unlocking or breaking of the padlocks, usually because of the short time available to the thieves, very often the whole rack and bicycles are stolen, particularly where the thieves belong to a well organized group.
Also, in conceiving new rack devices, particularly the complicated ones, the designer often pays little attention ~0 to the whole structure which then has projecting metal parts, usually pointed or sharp, that present a serious danger hazard, more serious where the racks are used by youngsters.

SUMMARY OF THE INVENTION
The purpose of the present invention is there-fore to provide a bicycle parking rack that avoids the above shortcomings by proposing a rack that cannot prac-tically be tempered with, in an attempt to steal the bicycles,or be bodily removed along with the ~icycles.
The rack of the invention uses, for each bicycle, a pair of pivotable upright locking arms each having locking bars provided transversely of their upper ends and intended to engage the two sides of a bicycle. Locking means : , .

~. ~

~2~

are provided on the bars to extend across the bicycle for locking lt when the arms are pivoted to lock position.
Additionally, the lower ends of the arms are pivoted by a mechanism which is located wholly within a hollow closed base such that the pivot mechanism cannot be reached for dismant~ing. Furthermore, the pivot mechanism is made to be solidly anchored into the ground to preven-t the rack and bicycle thereon to be bodily carried away.

More specifically, the invention is an anti-theft bicycle parking rack which essentially comprises:
an anti-theft bicycle parking rack comprising:
- an elongated hollow base member having a top wall formed with a pair of spaced holes, said base member defining a closed housing, when set on the ground, accessible only through the holes;
- a pair of bicycle locking arms for location on either side of a bicycle held transversely of said base member, each arm having a lower end inserted into ~ said housing loosely through one of said holes;
- pivot means, in said housing, secured to said base member; said pivot means mounting said arms, at said lower ends, for pivotal movement toward and away from the bicycle, between an inclined bicycle-release position and an upright bicycle-lock position;
- means for anchoring said pivot means solidly into the ground;
- wherein the diameter of said top wall holes is selected, with respect to the diameter of said arms lower ends, large enough solely to allow said pivotal movement of said arms between said positions;
- bicycle-engaging bars fixed to the upper ends of said arms, transversely thereof, and : ,' ....
., , . ,- . ~ ' ~ '- '~' .; , :: . , .

- bicycle locking means on said bars for exten-sion across a bicycle when said arms are in said lock position, for locking said bicycle to said rack.
Now follows the description of a preferred embodiment of the invention, having reference to the appended drawings:

BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 is a perspective view of a rack made according to the invention:
Figure 2 is a side elevation view;
1(~ Figure 3A shows, in cross section, the lower end of a locking arm in bicycle lock position while Figure 3B shows it in bicycle release position; and Figure 4 is a bottom plane view in cross section taken along line IV-IV of Figure 3A.

DESCRIPTION OF T~E PREFERRED EMBODIMENT

General description Figure 1 shows a rack 1 usable for separately locking two bicycles such as bicycle A and therefore including two locking-arm-and-bar combinations 3 both shown in lock position.
Each combination 3 comprises a pair of upright locking arms 5, smoothly bent at the top, each having a transverse bar 7 at its upper end and being pivoted, at its lower end, into a closed elongated base member 9 for movement between a lock and a release position, as shown in Figure 2. The bars 7 have, at their ends, pins 11 that are aligned when the arms 5 are in the lock position; the pins 11 extending in pairs between two successive wire spokes o~ the front and rear~ wheels of a bicycle A. At the center of the bars, in alignment of the arms 5, are two locking tabs 13 overlap-ping one another and having registering locking holes ' ': ., , . ~ ... ..
, ~ - ~ , .: ..

therethrough for the insertion of the shackle 21 of a padlock 23 (see Figure 2), or of a big U-shaped bicycle lock (not shown), when the arms 5 are in the lock position. I'hese tabs 13 are located be~ween the two cen-tral frame bars 15, 17, of the bicycle, as close to the pedal gear 19 as possible to make it almost impossible to break the padlock. The base 9 is solidly anchored into the ground.

Detailed description 1~
Since the combination 3 of locking arms 5 and transverse bars 7 is the same for each bicycle A, only one such combination will be described.
Referring particularly to ~igures 3A and 3B, the base member 9 is an elongated inverted channel member having a web as a top wall 25, side flanges 26 and closing end walls 27 so as to define, when the free edges of the flanges 26 and of the end of walls 27 are set on the ground, a closed housing 29. The top wall 25 has a pair of holes 31 which are the only access to the housing 29. It will be noted that the lower, preferably tubular, ends 33 of the arms 5 extend loosely into the housing 29.
Pivot means, secured to the base member 9, are provided within the housing 2~ to mount the locking arms 5 ~S for their pivotal movement toward and away from the bicycle between an inclined bicycle-release position (Figur0 3B) and an upright bicycle-lock position (Figure 3A~.
These pivot means comprise a base plate 35 fixed to the top of the horizontal leg of an L-shaped member 37 itself secured to the base member 9, such as by welding for instance. The base plate 35 and the horizon-tal arm of L-shaped member 37 have coaxial apertures 39, 41, that face the top wall hole 31. The pivot means also comprise an upright, preferably tubular and open-ended, column 43 fixed to the base plate 35 around its aperture 39, the column 43 projecting " ', . ~
: .

6~
into the lower end 33 of the locking arm 5. As best sho~n in Figure 4, a pin hole 45 is formed in one of the flanges
2~ of the channel 25. Similar holes, such as 47 (Figures 3A and 3B) are formed through opposed wall sections of the locking arm lower end 33 and of the colurnn ~3. These pin holes register with one another, that is they are coaxial, and are of essentially the same diameter. They serve as journal-bearings for a pivot pin 4g that extends across them, except hole 45 which serves only to slide the pivot pin 45 in position on the column 43 and the arm lower end 330 As shown in Figure 4, the p.ivot pin ~9 lies wholly within the closed housing 29 and since the entry hole 45 of the flange 26 is just sufficient to slide the pin ~9 into the housing, it will be appreciated that no ordinary tool can draw the pin 49 out of the housing. Pivoting is made possible by the bevel 51 at the lower edge of the locking arm 5.
Figures 3A, 3B and 4 show the top wall hole 31 to have a larger diameter than that of the locking arm 5, which larger diameter must be selected solely to allow the pivotal movement of the arm 5 between the bicycle-release position of Figure 3A and the lock-position o Figure 3B so as to prevent any possible access into the housing 29. In order also to protect the peripheral edge of the hole 31, the height of the column 43 is selected to cause the inner surface of the locking arm 5 to rest against the column 43, in the release position, so that the lower end 33 of the arm 5 stands completely free of the top hole 31, as clearly shown in Figure 3B. Addi-tionally, thè end edge portion of the lower tubular end33, away from the bevel 51, rests on the base plate 35 when the arm 5 is in lock position (Figure 3A). As shown in both positions of Figure 3A and Figure 3B, the lower end 33 is completely free of the periphery of the top wall hole 31.

~2~

The pivot means (base plate 35 solid with L-shaped member 37; column 43 and pivot pin 49) are solidly fastened to the ground, as aforesaid. This is obtained by a bolt 53, having an upper -threaded end and a preferably laterally bent, extending into the open ended hollow cylindrical column 43, through the apertures 39 and 41 and embedded into a concrete block 55.A nut 57 is screwed over the bolt upper threaded end to clamp the pivot means solidly on the base plate 35 which is itself solid with the base number 9.
It will be appreciated from the above description that the base member 9 and, along with it, the pivot means and the locking arm 5 are solidly anchored into the ground and could not be removed easily and rapidly by thieves.
Figure 2 shows the locking arms bent smoothly at their upper ends. The bicycle locking means, as aforesaid, comprise a pair of locking tabs 13 that overlap with locking apertures 59 thereof registering for the insertion of the shackle 21 of the padlock 23. The bicycle engaging bars 7 extend evenly on either side of the arms (Figure 1) at a predetermined distance from the aperture 59 of the locking tabs 13. The locking means further include the aforesaid pins 11 that project perpen-~5 dicularly from the bars 7 and are aligned in the lockposition of the rack. The pins 11 are intended for inser-tion between two successive wires spokes of the bicycle wheels while the tabs 13 extend within the fork of the bicycle, as close as possible to the pedal gear 19.
It will thus be appreciated that the bicycle parking rack as described above makes it extremely diEfi-cult for thieves to free the bicycle from the rack or to remove the rack completely with the bicycles thereon.
Additionally, it will be noted, from Figure 1 particularly, that the rack is of very simple construction and that the component parts are absolutely devoid of any sharp pointed features, being in fact mostly tubular elements not likely to cause injury.
