Description

AUXILIARY BICYCLE SEAT TECHNICAL FIELD This invention relates generally to bicycles and more particularly to auxiliary seats that can be assembled and disassembled on bicycles, such as for use by small children or other objects that accompany a teenager or adult.

BACKGROUND OF THE INVENTION Adult bicycles are usually equipped with a single seat on which the cyclist can sit while pedaling and driving. Often parents want a child to accompany them while riding a bicycle. Although the father can tie the child to his back in the form of a baby carrier, it is more common to sit the child in an auxiliary seat that is attached to the bicycle. Such a seat has been commonly mounted on the rear fender with the child's legs mounted on either side of the rear wheel. However, this arrangement has a variety of disadvantages. For example, the vision for the child is mainly that of the adult's back instead of the passing scene. Since the child is behind the cyclist, he must turn around in order to talk or inspect the safety of the child. There is also the probability that the child's foot hits the rear wheel. This positioning of the child also moves REF: 122712 the center of gravity of the bicycle loaded so far to the rear to seriously affect visibility. This design is expensive, requires a lot of time and skill, as well as a variety of tools to attach it. Likewise, the removal is difficult and takes a long time. For these reasons the child seats have been designed more recently to be mounted in front of the cyclist and just behind the handlebar tube or steering tube and the handlebar (or handlebar). This offers a lot of improvement with respect to the seats for children attached to the back due to the displacement of the child's weight from the back to the center of the bicycle. The main flaw of all centrally invented children's seats up to now has been the severe inherent lateral instability of the design. These designs do not create reasonable safety for the child and also increase the operational hazards for the cyclist. When the cyclist is interested in transporting objects instead of a child, the same problems arise in terms of instability. Despite the improved efforts of positioning a load to the center of the bicycle between the seat and the handlebar tube, current inventions do not consider the importance of taking lateral stability into account. Examples of such prior art designs are shown in the North American patents as follows: In U.S. Patent 579,514 entitled "SEAT FOR BICYCLES" by E, Collins, the claimed auxiliary bicycle seat is apt to sit on the horizontal bar or tube of the bicycle and to engage with the lower angular tube of the bicycle. As such, the invention only provides two points of stability for the traveler and does not ensure optimum lateral or rotational stability. In US Patent 3,902,737 entitled "CHILD CARRIER AND MOUNTING ASSEMBLY FOR BICYCLE", by I. Bergere and K. Welter, the child seat is attached by clamps to the cylindrical handlebar tube (steering column) and does not provide assured lateral stability. The seat can be allowed to swing out to the left or right causing an inappropriate weight shift. In U.S. Patent 4,305,532 entitled "UNIVERSAL BICYCLE CARRIER" by J. Reger, the child seat is attached to a 10 cm (4 inch) platform that only sits on the top structural support tube of a bicycle. men's bicycle without accessories or loose wedges between the handlebar tube and the seat post of a ladies' bicycle. The wedge in front of the platform that rests against the sides of the • handlebar tube is inadequate to provide vertical or rotational stability for the child's seat. further, the mechanism suggested for use as a footboard has no structural functionality and although its structural design is mounted on both sides of the upper structural support tube of a male and female bicycle it is only resilient wire that has flexibility for detachable annexation to The seat platform is not mounted on either side of the lower structural support bar of the bicycle. In yet another design, U.S. Patent 4,632,453, entitled 'UXILIARY SUPPORT SYSTEM FOR BICYCLE PASSENGER', by J. Robbin and J. Robbin, the child seat is attached to the upper tube and has nothing in the design to insure against severe rotational instability. Also, the bar of fasteners for the feet is attached to the upper tube.There is no security against the rotational instability in the same.Also, essentially no modern bicycle has a quantity of free space around the tubes of the handlebar necessary to ensure In yet another US patent 4,919,479 entitled "APPARATUS FOR CARRYING A PASSENGER ON A BICYCLE", by E. Loewke and D. Loewke, the child seat rests on the upper structural support tube and is centrally located It has a union to retain the front of the design but nothing to secure the rear end that mounts both sides from the back post. The last design is insufficient to prevent the lateral wobbling and with a light to moderate shock, the back of the design can be raised from the rest on the upper tube, possibly allowing the child to fall to the ground. In the North American patent 5,104,188 entitled 'BICYCLE SEAT FOR CHILDREN', by M. Jefferson, the child seat is supported centrally and around the upper tube, secured by a clamp.As the previous designs, inherently this can not guarantee against rotational instability. The vertical brace for use in women's bicycles is designed only to be mounted on both sides of the upper structural support tube of the bicycle allowing an inherent lateral instability Finally, in U.S. Patent 5,330,215 entitled "CENTER-MOUNTED PASSENGER SEAT FOR BICYCLE" ", by M. Bishaf and J. Faulhaber, the child's seat has a rear attachment by means of thin rods to the seat post and the front position rests on top of the upper tube. Not only will the rods be unable to prevent the child's seat from tig from side to side, there is nothing to prevent the superior instability of the front portion of the design. Thus, it is seen that there is still a need for a centrally located auxiliary seat for a bicycle, of relatively simple economic construction and still possessing a high degree of lateral stability. Accordingly, the present invention is concerned with the provision of such a need.

DETAILED DESCRIPTION OF THE INVENTION In a preferred embodiment of the invention, an auxiliary bicycle seat is apt to be transversally mounted to the upper and lower structural support tubes of a bicycle, between the seat tube of the bicycle and the handlebar tube. (or tube or steering column). The auxiliary bicycle seat of the present invention comprises a seat support that supports a seat, a front support brace that extends downward from a front portion of the auxiliary seat to the top structural tube of the bicycle and a rear support brace designed as described later herein. Means are provided to secure the front support brace securely to the upper tube. In a preferred embodiment of the invention, the rear support brace comprises fork support rods extending downwardly from the seat support at a distance sufficient to be mounted on both sides of the upper and lower structural tubes of the bicycle. Another modality contemplates a horizontal brace on which the feet of the child can rest, provided with means to mount the brace to the posterior support rods. The horizontal brace can be attached to the back support rods either just above or below the lower structural support tube to fit the lengths of the child's legs. Specifically, the highest placement will accommodate children of approximately 1 1/2 - 4 years of age, the lowest placement will accommodate the length of the legs of children approximately 3 - 9 years of age. Another object of the invention is to provide an auxiliary bicycle seat capable of being semi-permanently mounted to a bicycle. Another object of the invention is to provide an auxiliary bicycle seat having lateral structural stability. Still another object of the invention is an auxiliary bicycle seat that can be mounted to a mulicity of bicycle designs that include a standard racing bicycle (for men and for women), a mountain bike and single fiber tube designs of glass of the state of the art as illustrated herein (Figures 10 to 13). In one embodiment, the invention includes a horizontal stabilizer bar, in addition to the brace projecting downward, in fork, rear, to stabilize the auxiliary seat in bicycle designs that either have no upper structural bar or that have a bar structural upper which is severely angled from the horizontal of the handlebar tube to the tube of the seat post of the bicycle. Still another object of the invention is to provide an auxiliary seat that has support for the feet, adjustable, for a child occupant. Still another object of the invention is to provide an auxiliary seat or platform on which animate or inanimate objects can be placed. In this embodiment, the auxiliary seat has a bifurcated forward structural support that is mounted on both sides of the upper and lower bicycle structural bars. The bifurcated forward structural support can be attached either to the lower end of the rear structural support or can simply be secured to the upper and lower bars of the bicycle, as in the case with the rear structural support (see Figures 18 and 22). This mode can also support any number of objects as illustrated in the drawings. Still another object of the invention is to provide a separable seat platform for either a human to sit, as in a typical bicycle seat or a flat platform for carrying bulky objects.

Figures 23a and 23b illustrate uses for the seat support platforms, particularly for use for inanimate objects, such as a toolbox or annexing a child seat that begins to walk.

DETAILED DESCRIPTION AND MODES FOR CARRYING OUT THE INVENTION With reference now in more detail to the drawings, in Figures 1 and 2 it is shown that the upper and lower structural support bars of a bicycle having an elaborate cylindrical bar frame including an almost horizontal upper tube 11, which in turn is joined to an upper portion of a handlebar tube (or steering tube) 12. A lower tube of the lower frame or tube 13 extends back and down from a lower portion from the handlebar tube 12 to an almost vertical bicycle seat tube (not shown). The auxiliary seat 14 is constructed to have a seat cushion 15 or other seat design mounted to a seat support 16. A front support brace 17 is attached to the underside of the seat support 16., which is designed to have a concave arcuate lower end 18 which allows the support to come into contact with a partial circumference of the upper structural support bar 11 of the bicycle. The front support brace 17 is further equipped with attachment means such as a strip 19 for stabilizing the front end of the seat relative to the upper bicycle support bar 11. In a preferred embodiment, the means of such a stabilizing joint consist of a hook and eye fastener, such as a VELCRO strip. Alternatively, the stabilizing joint of a strip 19 can be by clamps, screws or other such means commonly understood by those skilled in the art. The back support brace 20 consists of a bifurcated or fork construction and has an upper bridge portion 28 from which two legs 29 descend in spaced apart side-to-side relationship. The exposed bottom 30 of the bridge portion 28 is arcuately formed in such a way that it can be mounted leveled on the cylindrical upper structural support tube 11 of the bicycle. In a preferred embodiment, the exposed bottom 30 and the area of the legs adjacent the exposed bottom 30 are able to accept an insert 34 (see Figure 3) which can be semi-permanently attached to the auxiliary seat by any number of attachment means ( for example, bolt, bolt, clamp) such that the auxiliary seat 14 can remain in a horizontal position relative to the ground when used on a bicycle having a top support bar that is angular to the horizontal of the handlebar tube to the bicycle seat support tube (as found in mountain bikes and for women). Additionally, the front support brace 17, exposed bottom 30 and insert 34 may include indentations 72 positioned transversely therein to accommodate shifting cables that are routinely located longitudinally along either the upper structural support bars and bottom of the bicycle. The two legs 29 extend a distance beyond the lower structural support tube 13 of the bicycle frame. It is the fact that the rear support legs extend downwards at a distance below the lower structural support bar of the bicycle which provides the present invention with the capacity not hitherto recognized for lateral stability. The inward facing sections 50 (FIGS. 3 and 4) of the legs 29 near their respective remote located terms are equipped with receiving means 51 of the arched lower structural tube to receive the lower tube under pressure. One embodiment of the invention incorporates two such reception means 51 for accommodating bicycles of various dimensions. The arcuate receiver means 51 may include resilient blocks or bearings 31 that can be secured within the arched sections of the legs. The resilient blocks or bearings 31 can also cover the arched bottom of the front support brace 17 and the rear support reinforcement bridge 28. Thus, previous references to leveled assemblies intend to include these bearings which are functional to protect the paint of the bicycle and to increase the friction between the auxiliary seat and the bicycle support tubes. In a preferred embodiment, the lower arched receiving means of the rear support brace 29 are vertically adjustable (FIG. 5) to easily accommodate any number of bicycle designs, such as by means of a rack slide having arched receiving means 52 attached to the same The receiving means 52 can be mounted semi-permanently to seat zippers 53, which have a rear rack internal surface 54, nipples 55 of receiving means and side flanges 59 which in turn provide a means to prevent the zippers 53 of the seat from slipping forward or backward. The zipper surface 54 of the zipper 53 of the seat engages the zipper surface 56 when compressed to eliminate vertical slippage of the arcuate receiver means 52. The receiver means 52 is additionally designed to engage with the seat rack 53 having a multiplicity of nipple receivers 57 incorporated in the rear side of the receiving means. Additional adhesion of the receiving means and seat zips is provided by a double sided adhesive tape 58 positioned between the receiving means 52 and the zipper 53 of the seat. The receiving means 52 can be made to accommodate bicycles with variable diameter of the lower support bars as shown in examples I, II and III of Figure 8. In a preferred embodiment, the receiving means 52 are made of plastic and have blocks or bearings 31 attached to their respective arcuate surfaces. In another embodiment, the receiving means 52 can themselves be resilient, as it would appear if they were composed of a resilient plastic. The rear support legs 29 are secured to the bicycle by a screw 37 (figures 3 and 4) or other such means commonly used to create inward or lateral tension between the legs, such that either the fixed arched receiving means 51 or the adjustable 52 can be brought into contact with the lower structural support bar of the bicycle in a secure manner. For example, the screw 37 can be directed to pass through the channels 38 and the threaded channels 39 located in the support reinforcing legs and / or under the lower structural support tube 13 of the bicycle (see figures 3 and 5). ). The auxiliary bicycle seat may also include a transverse rib 32 (Figures 2 and 4) having an arcuate portion on its upper surface 61 on which another resilient bearing or block 31 is fixed. The cross brace has two vertical slots 33 and is apt to be mounted to the legs 29 of the rear support brace just below the upper structural support tube 11 of the bicycle. The cross brace 32 can be detachably attached with fasteners 36 for example screws or the like by passing the rods of such screws through slots 33 and then screwed into threaded channels 35 in the legs 29. The slots 33 thus allow The cross brace is mounted under pressure under the top cylindrical structural support tube of the bicycle of various diameters, depending on the make and style of the particular bicycle to which the auxiliary seat is to be mounted.

In one embodiment of the invention, the rear support legs 29 and the cross brace 32 have rack surfaces 62 (FIGS. 1 and 2) to provide a means by which such cross brace 32 can be prevented from slipping from a secure fit. . The auxiliary seat further comprises a pair of stirrups 40 which are mounted on top of a transverse rod 41 which in turn is removably mounted to the front part of the rear support legs 29. The crossbar 41 can be mounted by any means reasonably understandable by anyone of ordinary experience, in which screws, clamps, etc. are included. The cross bar 41 may include a zipper surface 63 along the back-to-back side to engage with the zipper surface 64 of the forward facing surface of the rear support legs 29 to help prevent slippage of the zipper. the crossbar. The auxiliary seat is easily mounted to the bicycle by mounting on both sides the legs 29 of the rear support brace on top of the upper tube 11 of the bicycle, tightly behind the column 12 of the handlebar tube. The connecting means of the front support brace, strip 19, are then firmly secured around the upper tube. Then the cross brace 32 is mounted to the rear support brace legs 29, under the upper tube 11 of the bicycle and securely secured therein with fasteners 36. Then the legs are secured via the lateral tension means, such as bolts 37, in such a way that the receiving means of the adjustable arched lower support bar are positioned adjacent either on one side or the other of the lower support bar 13 of the bicycle. Finally, the crossbar 41 with stirrups 40 is mounted to the front of the legs 29 when the bolts 42 are inserted through channels 43 and into the threaded channels 44. (figure 4) and tight - firmly. As shown by. In the broken line image in Figure 2, the cross bar can be mounted higher up the legs 29 of the rear support brace 29 using a pair of alternating bolt channels 45, spaced apart, to accommodate a child of smaller stature. In another embodiment of the invention (Figure 23b) where a very small child will occupy the auxiliary seat, no crossbar is needed. Instead of this, the foot supports can be permanently or detachably attached to the seat support 16 or integrally associated with the seat itself. In still another embodiment of the invention, wherein the auxiliary seat is contemplated for use on a lady's bicycle or other type of bicycle having structural support bars that abruptly deviate from the horizontal as shown in Figures 9a and 9b, the auxiliary seat may include a plug-in bar 70 which can be mounted first on the bicycle by joining the bar to the plug securely to the handlebar tube 12 and seat post 71 in a horizontal manner. Then the auxiliary seat can be secured to the bicycle as described above. In still another embodiment of the invention, the auxiliary seat provides the presence of cables for changes of speeds that are systematically associated with the upper and / or lower structural support bars of the bicycle. For example, the insert 34 may include notches 72 (FIG. 5) while the arched receiver means 52 (FIG. 7) may have cable channels 73. The auxiliary seat, when mounted to various bicycle designs, will have the overall appearance as illustrated in Figures 10 to 13. Figure 10 illustrates a typical mountain bike in which the upper structural support bar is slightly offset from the horizontal and thus would require the use of the insert 34. Figure 11 illustrates a typical racing bicycle that has an almost horizontal upper support bar, in which case the auxiliary seat would not require the insert 34. Figure 12 illustrates a typical lady's bicycle, which has upper structural support bars that abruptly deviate from the horizontal, thus requiring the use of a plug-in bar 70. Figure 13 illustrates a high-tech bicycle design that also requires the use of the plug-in bar 70. In still other embodiments of the invention, the auxiliary seat can be designed to support bulky materials such as a child seat that begins to walk or inanimate objects of dense mass, such as a toolbox. Figure 14 illustrates that the seat cushion 15 is releasably attached to the seat support 16. Once the seat cushion 15 is removed, the platform 80 can be attached to the seat support 16 by any reasonable joining means, in which screws, bolts or clamps are included. Position of the platform 80 is larger than the seat cushion 15, the platform can be further stabilized by connecting to the same front support rods 81 from the front end of the platform, such as by screws or bolts and at the end bottom of the rods to the rear legs 29 when using the channel 38 and the threaded channel 39 located at the distal end of the legs 29. Once the platform 80 and the front support rods 81 are mounted, the auxiliary seat will have the appearance shown in figure 18.

In still a further embodiment of the invention, where a more substantial platform is to be used, Figure 19 illustrates a plan view of the platform 90 having two front support braces 91 attached thereto, each of which includes arcuate receiver means 92 to encompass a front portion of a lower support bar of the bicycle. The front support braces 91 can be held in place by lateral tension means similar to those of the rear support braces. When properly assembled as shown in Fig. 22, the platform 90 is attached to the seat support 16 and the front support braces 91 are mounted on both sides of the upper and lower support bars of the bicycle in the manner of the hind legs 29. It is now seen that an auxiliary seat serving as a child seat or other proposed platform is provided for a bicycle, which is of a relatively simple and still safe configuration and that can be easily mounted to bicycles having bars. of various sizes and orientations of specific bars. Preferably, it is made of plastic materials. An adjustable seat belt or belt can also be attached to the underside of the seat support 16, just behind the back of the rear support brace, with a plurality of screws or the like. Additionally, strips can be attached to each stirrup to keep the child's feet fixed in the stirrups. Once the auxiliary seat is mounted to the bicycle it is completely stable and secure from any forward or backward movement, upwards or downwards or laterally to the left or right or any torsional or twisting forces. The child, wearing a helmet, sitting in his child seat with a seat belt and foot bands in place, is exceptionally safe. In addition, the child is surrounded by the arms of the cyclist and still has a good view of the road. The child can hold onto the handlebar and learn to participate in balance, addressing, changing gears, road signs and safety. The conversation is easy with the child's ears right in front of the operator's mouth. The child is not only surrounded by the arms of the cyclist but is located just above but out of the path of the cyclist's thighs. Although the invention has been specifically shown and described in its preferred form, it should be understood that any modifications, additions and cancellations can be made thereto without departing from the spirit and scope of the invention as summarized in the following claims.

It is noted that, in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it refers.
