The present invention relates to an attachment facilitating device for a bicycle and, in particular, to a device that facilitates the attachment of various types of carriers to a bicycle.
The prior art includes various carriers for mounting between the saddle and the handlebars of a bicycle. If the carrier is a child carrier, this location has the advantages that the child can have a good view forwardly of the bicycle and is given a sense of security by being located between the arms of the rider, while the rider can observe the child.
Besides child carriers, it is known to attach other types of carriers to a bicycle. For example, pet carriers such as those of the type disclosed in U.S. Pat. No. 6,179,183 of Kloster can be attached to a bicycle. The pet carrier disclosed in Kloster is mountable on a top tube of a bicycle. In addition, this carrier can also be mounted on a female-style bicycle. For comfort purposes, the sidewalls of the carrier disclosed in Kloster have a plurality of air ventilation openings.
A support beam, such as those of the type that have the effect of converting a female-style bicycle into a male-style bicycle, can be used to facilitate mounting a carrier between the saddle and the handlebars of a bicycle when, for example, the bicycle lacks a top tube; however known “conversion” beams are inadequate for certain applications. For example, shorter or plumper individuals sometimes prefer the use of a female-style frame with a large space in front of the saddle. The beam design of the prior art effectively removes this space when mounted to the bicycle. As well, certain modern frame designs with a radically sloping top tube sloping upwardly aid forwardly, with a minimal seat tube can mace it difficult to satisfactorily mount a carrier in a horizontal disposition,
The term “bicycle” refers to a conventional upright adult bicycle and does not include a recumbent bicycle nor the like.
The term “clamp” as used herein means two or more cooperating elements for holding at least two things firmly together (unless a different meaning is evident from the context within which the term is used).
According to one example of the invention is an elongate support for a bicycle-mounted carrier that mounts between the saddle and the handlebars of a bicycle. The support includes first and second ends. A first clamp is associated with the first end for gripping a tubular member of the bicycle adjacent to the handlebars. A second clamp is associated with the second end for gripping a tubular member of the bicycle rearwardly of the first clamp. First and second elongate arms are slideably engageable with each other. The first and second arms each have a proximal end region opposite their respective distal end regions associated with the clamps. The first arm is for supporting the carrier and is fastenable thereto. The second arm includes a linear region extending from the distal end of the second arm towards the proximal end of the second arm. An angled region is adjacent the linear region. At least two fasteners enable fastening of the first and second arms together in either of at least two orientation-differing relationships. In one of the two relationships, angling out from the lineal region is in one direction. In the other of the relationships, angling out from the linear region is in a different direction.
According to another example of the invention is an elongate support for a bicycle-mounted carrier that mounts between the saddle and the handlebars of a bicycle. The support includes first and second ends. A first clamp is associated with the first end for gripping a tubular member of the bicycle adjacent to the handlebars. A second clamp is associated with the second end for gripping a tubular member of the bicycle rearwardly of the first clamp. The support also includes an elongate member for supporting the carrier and fastenable thereto. The member includes opposed sidewalls, a web spanning the sidewalls, an interior space between the sidewalls, and a joining end region opposite a clamp end region associated with the first clamp. A pair of bars each has a linear region and an angled region. Each of the bars is for fastening to one of the sidewalls. The linear region is associated with the second clamp. The angled region is adjacent the linear region. At least two fasteners enable the fastening to the sidewalls in either of at least two orientation-differing relationships. In one of the two relationships, angling out from the linear region is in one direction. In the other of the relationships, angling out from the linear region is in a different direction.
According to another example of the invention is a pet carrier for carrying a pet. The pet carrier is mountable on either one of a top tube of a bicycle, a support beam. The carrier includes a housing defining an interior space within which the pet can be placed. The housing includes a front side portion, a back side portion, a base configured for connection to the bicycle and an open top (or a removable top cover at a top of the housing). A net-like restraint is attachable to the housing for pressing against a back side of the pet when placed in the carrier. The net is for restraining movement of the pet towards the back side portions. A chin rest is located substantially at the top along the front side portion.
It may be convenient if the carrier housing includes at least one compartment for storing items.
It may also be convenient if the at least one compartment is sized to store a water bottle.
It may also be convenient, where the carrier housing includes a removable top cover, for the cover to be grid-like for facilitating ventilation.
Other aspects and features of the present invention will be apparent to those of ordinary skill in the art from a review of the following detailed description when considered in conjunction with the drawings.
Reference will now be made by way of example, to the accompanying drawings which show example embodiments of the present invention, and in which:
Similar reference numerals may have been used in different Figures to denote similar parts in the illustrated apparatuses.
The arms 20 and 22 engage each other in a manner such that they may telescope to adjust the overall length of the beam 18. Further, as will be described below, the rear arm 22 may be put into any one of multiple different orientation relationships with the front arm 20 in order to change the relative position of the clamp at the rear arm's distal end. In
Front arm 20 comprises an elongate channel-shaped member having all inverted U-shaped cross-section, composed of sidewalls 1 and a web 2 spanning the sidewalls 1. There is an interior space between the sidewalls 1 (i.e. the space of the channel), and the proximal end of the arm 22 (end opposite the distal end) is slideably engaged with the interior surface of the arm 20. The rear arm 22 comprises two substantially parallel spaced apart bars 26 and 28, which in the illustrated embodiment are generally strip-like in shape, with each bar being fastened to a corresponding inside surface of a sidewall 1 of the front arm 20.
Referring to
Both front and rear arms include front clamp or clamp assembly 66 and rear clamp or clamp assembly 74 respectively at their distal (free) ends (the distal end of the front arm 20 is end 58) for releasably fastening the beam 18 to a bicycle. The clamp 74 is for releasable attachment to a seat tube or seat post of a bicycle frame. Also, a first region of the clamp 74 is releasably attached to the region 31 of the bar 26. A second opposed region of the clamp 74 is releasably attached to the region 31 of the bar 28. The front clamp 66 joins the front arm 20 to the bicycle at a position close to the handlebars, such as the head tube of the bicycle frame.
With respect to the support illustrated in
The front and rear arms are joined together by aligned slots and holes within the respective arms. Thus, there are a plurality of spaced apart holes 42 along the bars 26 and 28. In one particular version of the rear arm 22, there are seven of the holes 42 per arm, and the holes are evenly spaced apart from each other. The holes 42 may be aligned with slots 46 within the sidewalls of the front arm 20. These holes 42 are designed to receive fasteners, to fix the position of the rear arm 22 with respect to the front arm 20 once the support has been telescoped to the desired position. Each bolt of the fastener is fitted through both an elongate slot 46 and one of the holes 42. In one embodiment, increased rigidity is achieved by using two spaced apart fasteners per side. Although only one of the elongate slots can be seen in the drawings, there are two opposed elongate slots 46 formed in the opposite sidewalls 1 of the front arm 20. The size of the slot 46 will vary depending upon such factors as the size of the holes 42 and the desired number of holes to be exposed through the slot. The holes 42 and the slot 46 should not be so large as to result in the loss of rigidity. Reversible fastener means is provided by the slots 46, the holes 42 and the associated fasteners. It will be appreciated by one skilled in the art that the fasteners could be detent mechanisms instead of nut and bolt combinations. Also, it will be understood that other types of reversible fastener means are contemplated, and that these need not include slots and/or holes.
Use of single fastener per side permits angular adjustment of arms (as will be subsequently described), while multiple fasteners are useful when a linear beam will suffice.
Referring to
Two different front arm-rear arm orientation relationships are shown in
Each of the bars 26 and 28 have a linear region 31 and an angled region 33. The linear region 31 is associated with the rear clamp 74. The angled region 33 is adjacent the linear region 31. As shown, the angled regions of the bars displace the clamp either above or below the mid-plane of the beam.
Changing the configuration of the support from that of
In order to assist in understanding the illustrated support, one can visualize an axis parallel to the length of the front arm 20. This axis extends through the front end 58 and rear end 59 of the front arm 20. One can then visualize another axis extending through the front end 58 and the end 32. Flipping the rear arm 22 provides a means for varying the angle between these two axes. When the support is attached to a bicycle, the configuration of
The front clamp assembly 66 attaches the support to the bicycle. More specifically, the front clamp assembly 66 grips a tubular member of the bicycle in the handlebar region, such as the head tube 70 (or handlebar stem, although this would be less suitable and unlikely in light of the rotation of the stem). The front clamp assembly 66 is a conventional operable clamp for gripping a tube such as that described in the previously mentioned U.S. patent application. Preferably, the clamp 66 is generally horizontally oriented to grip a generally vertical tube. However, one skilled in the art will appreciate that when suitably modified the clamp 66 may grip any part of the front region of the bicycle, such as the forward region of the top or down tubes. The clamp 66 includes two openable and opposed regions 67 and 69 which are best seen in
The rear clamp assembly 74 grips seat post 78, and is of a conventional openable arrangement such as that described in the previously mentioned U.S. patent application. The rear clamp assembly 74 includes bridge assemblies (which each include a rigid spacer 37 and a compressible sleeve 40) and resilient sleeves 30. The bridge assemblies maintain the bars 26, 28 in parallel spaced apart relationship while also compressing in length when tightened to form a mount to attach the device to a seat post or seat tube. Centrally in each of the bridge assemblies is a rigid spacer 37, which could comprise a bolt. Providing a rigid spacer is clearly not essential to the invention. It will be understood that the bridge assemblies could easily be replaced by something else which might include, for example, a foam piece.
The pair of resilient sleeves 30 which are of hollow rectangular cross-section fit onto the bars 26 and 28 at the end 32 between the bridge assemblies. The illustrated sleeves 30 permit compensation for different seat post sizes and are further described in the previously mentioned U.S. patent application. The sleeves provide both cushioning and grip when engaged with the bicycle frame or post. While the sleeves 30 are useful, there are suitable alternative clamps that do not employ sleeves. Also in certain circumstances the compressible sleeves 40 might be able to maintain the rigidity of the mounting.
For the particular bicycle shown in
For those bicycle frames such as the exemplary frame depicted in
It is therefore typically desirable to have the front arm 20 (to which the carrier would be attached) substantially horizontal. Pivoting the strip-shaped bars 82 downwardly permits the rear clamp 74 to grip the seat tube or seat post near the junction of the top tube for greater strength and less interference with the rider. It also permits use of the device with a shock-absorbing seat post. Also, it could allow a short bicycle rider to lower his or her saddle all, or nearly all the way down.
Before the front clamp assembly 66 and the rear clamp assembly 74 are clamped to the head tube 170 and the seat post 178 respectively, the rear arm of the support can pivot away or towards the axis through the ends 58 and 59. After both the front clamp assembly 66 and the rear clamp assembly 74 are in gripping engagement with the head tube 170 and the seat post 178 respectively, the rear arm of the support cannot substantially pivot away or towards the axis through the ends 58 and 59.
The support illustrated in
The support illustrated in
Means for keeping the strip-shaped bars 26 and 28 spaced apart is provided. In particular, nut and bolt assembly 202 extends through compressible cylindrical sleeve 206 (the sleeve 206 can be the same sleeve as the sleeve 40 illustrated in
The rear arm 22 can pivot with respect to the front arm 20, via a pivot or pivot joint 215 comprising a pair of fasteners such as nut and bolt combinations 216. In the illustrated embodiment, the front and rear arms are joined at the pivot joint 215. Also, the fasteners 216 can be of the type that, when sufficiently tightened, prevent further pivotal movement. It will be appreciated by one skilled in the art that the illustrated pivot joint 215 is only one possible means to pivotally attach the rear arm 22 to the front arm 20 and permit pivotal movement thereof.
The rear arm 22 also has a clamp 218 at its distal end. The clamp 218 permits attachment of the distal end to the frame of a bicycle. The clamping device can be any type of conventional openable clamp having opposing members for gripping a tube, and the illustrated clamp 218 is similar to a clamp sold under the trademark Krypto. This particular clamp can be pivoted with respect to the rear arm 22 in order to better facilitate attachment to more than one possible tubular member.
In
Changing the tubular member clamped by the clamping device 218 is again possible. For the bicycle and support illustrated in
Whereas a carrier in the form of a seat and headrest assembly for an infant is illustrated in
The illustrated carrier tapers towards the bottom of the carrier 550. There is not an important functional reason for this, but this characteristic might permit reduced injection molding costs. In one example embodiment, the backside portion of the pet carrier tapers more acutely towards the rear as compared to the illustrated backside portion 558.
In the lower region of the housing 554, an elongate channel 566 extends from the backside portion 558 to the front side portion 562, permitting the carrier 550 to straddle an elongate member or beam (such as the beam 18 illustrated in
In
It will be understood that it may be desirable to have the lid 570 completely separated if a large enough dog is being placed in the carrier 550. On the other hand, in the case where a cat (or a small puppy) is being placed in the carrier 550, the lid 570 can be simply lifted up but not removed before the pet is placed in the carrier 550. In conjunction with this second scenario, a fabric patch 580 is provided to partially restrict a hole in the lid 570 through which the head of the pet can extend. Ties 584 are used to expand or restrict opening 586 through which the pet's head can extend.
If a pet is placed inside the carrier 550 and the lid 570 is returned to a closed position, it will be desirable to prevent the lid 570 from becoming dislodged from the closed position. Various known locking mechanisms can be employed to prevent undesired dislodging from the closed position. In one example embodiment, a latch-type mechanism (possibly one that is engaged by rotation action) is employed. In another example embodiment, the periphery of the carrier's lid can fixedly engage an adjacent edge of the carrier 550 in a manner somewhat similar to Tupperware® containers.
Depending upon the pet placed in the carrier 550, padding could be added at locations such as chin rest 616 and the carrier floor upon which the pet is placed. It will be appreciated that certain types of padding are less likely to be chewed by the pet. Also, significant interference with the means for providing air flow within the housing 554 may be undesirable.
Side walls 600 and front side 604 of the carrier 550 include a plurality of ventilation holes 608 for comfort purposes. In
The top cover 570 also facilitates ventilation. This is due to the fact that it is grid-like. It will be understood that the grid-like portion of the lid 570 need not be made of plastic. For example, the grid-like portion could consist of metal wiles.
Although the illustrated lid is flat in regions, various lids of different shapes are possible. For example, the lid could have regions that bulge out.
Located below the floor 620 of the carrier 550 are storage compartments 624 and 628. In the illustrated embodiment, the storage compartment 624 is sized to house a standard sized water bottle. The compartment 628 is designed to hold miscellaneous articles, and can be accessed through an opening in the associated side wall 600. The storage compartment 624 is accessed by opening compartment cover 633, which preferably swings up or pops out. Tile cover 633 can be held closed in a variety of known manners, such as by means of a catch.
As shown in
Either front-attached leash 732 or rear-attached leash 734 is connected to pet collar 736 to further secure the pet 710 within the carrier 550. One or more apertures 738 or the ventilation holes 608 can permit connection of clasp-opposite end of the leash 732 or 734 to the housing 554.
When the carrier 550 is not attached to a bicycle, it may be useful for the carrier 550 to include means for facilitating a person to carry the carrier 550 around with him. Referring to
Other seat belt attachment means are contemplated. For example, a pet carrier constructed in accordance with one example embodiment could include one or more suitable slots extending through the pet carrier housing from one of its side walls to the other in order to connect a car safety belt to the pet carrier.

In
Although the described embodiments of the support are designed to support loads of up to 50 lbs, loads well above 50 lbs are not intended. Because of likely bicycle instability, it would be usually unadvisable in any event to ride a bicycle with an additional load of say 200 lbs.
It will be understood that if the carrier attached to the support is too large, a person's ability to ride the bicycle could be affected. In an example embodiment, all dimensions of the carrier are less than 0.5 m.
While the invention has been described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended to embrace all such alternatives, modifications, and variations as fall within the spirit and broad scope of the appended claims.
