Description

The utility model relates to the field of support devices for transporting bicycles by vehicles and storage on them, namely, devices for transporting bicycles placed by cars. Also, the utility model can be used as a device for temporary storage of a bicycle by attaching it, for example, to a car.

This utility model considers the proposed device as an example of its attachment to a car for the purpose of transporting a bicycle. This is an external attachment of the bike.

Currently, for transporting a bicycle, means or devices are used to secure it on the roof of the car (the bicycle is mounted in a standing position longitudinally to the car) or behind the car by attaching a rack or frame on which the bike is transverse to the car. Both techniques have serious flaws. First of all, the bike has a weight and for attaching it on the roof of the car or on the frame at the back of the car, the user must raise the bike to a predetermined height, hold it in position at that height and fasten the bike. The bicycle is a flat, developed structure with an unstable position of the front wheel and handlebar, which, of course, creates an inconvenience in attaching it at a height. Such an operation also requires sufficient physical effort, which, for example, will be difficult for women. In addition, when fixing the bicycle in a standing position on the roof of the car, the latter seriously increases windage and center of gravity. This affects maneuverability and, in general, transport safety. And when fastening the bike across the car, the end parts of the bike go beyond the transverse dimensions of the car and constitute a hindrance both to the car (for example, the view through the rear glazing of the car worsens) and to other participants of the antennal movement (due to the protruding parts of the bike - oversized cargo).

It is more promising and safer to fasten the bicycle in the rear of the car in a vertical position with the plane of the bicycle coinciding with the longitudinal axis of the car. In this case, the view through the rear glazing is preserved and there are no protruding parts that other drivers might consider as interference.

For example, there is a device for securing a bicycle on a vehicle, comprising a support strut that is mounted on the roof exit to the rear tailgate and which is used to secure the front wheel of the bicycle, and a support element that is secured under the rear tailgate and which is used for fixing the rear wheel of a bicycle (US 2018126917, B60R 9/048, B60R 9/10, published on 05/10/2018).

This decision is made as a prototype.

With such a fastening, the bicycle is practically in an upright position with a slight slope towards the hood of the car and its plane is spread out in a vertical plane passing through the longitudinal axis of the car. In this decision, there are no parts protruding beyond the transverse dimensions of the car, and the bicycle itself performs the function of a wing to increase the directional stability of the car.

The disadvantage of this solution is that to secure it, you need to raise this bike to a predetermined height, put its front wheel (and it is not fixed and therefore can be rotated) in the support leg cradle and fix the front wheel in this cradle. After that, the rear wheel of the bicycle is fixed. Since the bicycle has a developed spatial design and has a weight, only a healthy and strong user can perform such operations. This limits the range of users (women, adolescents, people with limited ability to move hands, etc.) and creates inconvenience in the implementation of the attachment process.

In addition, the front wheel of the bicycle is fastened with clamps, which does not give such a guarantee a guarantee of its reliability. In the absence of skills to knit knots and with the wrong choice of clamps, there is a danger of spontaneous untying of the fasteners or its weakening. Another feature is that the place of fastening of the support stand is located on the roof of the car, which a priori stipulates that the user should be higher than the height of the car so that he could put the bicycle wheel raised above the roof into this lodgement and fix it.

This utility model is aimed at achieving a technical result consisting in the reliability of securing a bicycle to a car by a user of any height and any physical capabilities by fixing the front wheel when the bicycle is horizontal and being lifted by elastic means.

The specified technical result is achieved in that in the device for securing the bicycle, comprising a vertically orientated rack mounted on a supporting surface, a carrier unit for securing the front wheel of the bicycle, the rack is made in the form of a vertically oriented elongated profile, and the node for securing the front wheel of the bicycle made in the form of a carriage located in the guides of the profile with the ability to move along the length of the latter and spring-loaded relative to the profile d I forcibly move it from the lower to the upper position, the carriage is made with a plate pivotally mounted with the possibility of swinging the carriage body, the upper end of which is opposite one shoulder of two angular levers, the other shoulders of which are equipped with stops, are perpendicular to the plate and the carriage body and at a distance relative to each other to form a gap for entering between the front wheel of the bicycle and moving towards each other with the pressure of the plate on the first of the said angular shoulders levers, at the other lower end of the plate there is fixed a knot for its fixation relative to the profile at the lower position of the carriage and the upper end of the plate is located at a distance from the first of the said angle arms, the carriage in the lower part is made with a frame shape by extension with a through longitudinal opening to fix the front position a bicycle wheel carrying a retractable ramp for rolling the bicycle wheel to this extension, and is equipped in the upper part with an articulated lever, one shoulder of which is equipped with dstvami contact interaction with a profile for locking the carriage from moving along the profile, and the other is elongated and disposed in front of the upper end of the plate to open the contact interaction with the profile of a pressure on it front wheel of the bicycle.

These features are significant and are interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The present utility model is illustrated by a specific example of execution, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving the required technical result.

According to the present invention, the construction of a device for securing a bicycle, preferably on the rear surface of a car body, is considered. Moreover, this device is considered not only as a device for transporting a bicycle, but also as a means of storing a bicycle (for long-term parking of a car, for example, in a garage). A feature of the claimed device is that it is fixed in a vertical direction with the front wheel up and with the location of the plane of the bicycle (a plane passing through the straightened wheels) in a vertical plane passing through the longitudinal axis of the car or parallel to it. With this arrangement, the rear view for the driver through the glazing and the rearview mirror (view) is preserved, the position of the center of gravity of the car practically does not increase and the directional stability is increased due to the work of the bicycle design as keel plumage. The claimed invention allows a user of any age and any physical abilities to ride a bicycle on a rack and set it in the vertical direction due to the fact that when the front wheel of a bicycle is placed on a rack, the carriage starts to lift the wheel up until the rear wheel of the bicycle stands on the rack.

In the General case, the device for securing the bike contains mounted on the supporting surface orientated in the vertical direction of the rack, bearing a node for securing the front wheel of the bicycle. The stand is made in the form of a vertically oriented elongated profile, and the assembly for securing the front wheel of the bicycle is made in the form of a carriage located in the guides of the profile with the ability to move along the length of the last and spring-loaded relative to the profile for its forced movement from the lower to the upper position. The stand is made in the lower part with a support plate extending laterally from the profile and equipped with a retractable ramp for rolling the bicycle wheel onto the support plate. The carriage is made with a plate mounted pivotally with the possibility of swinging on the carriage body, the upper end of which is opposite one shoulder of two angular levers, the other shoulders of which are equipped with stops, are perpendicular to the plate and the carriage body and at a distance relative to each other to form a gap for the input between them of the front wheel of the bicycle and moving towards each other with the pressure of the plate on the first of the said shoulders of the angle arms. At the other lower end of the plate there is fixed a knot of its fixation relative to the profile at the lower position of the carriage and the location of the upper end of the plate at a distance from the first of the said arms of the angle arms. The carriage in the lower part is made with a frame-shaped extension with a through longitudinal opening for fixing the position of the front wheel of the bicycle carrying a retractable ramp for rolling the bicycle wheel to this extension, and is equipped in the upper part with an articulated lever, one shoulder of which is equipped with means of contact interaction with the profile for locking the carriage from moving along the profile, and the other is made elongated and located in front of the upper end of the plate to open contact interaction with the pros lem with pressure on it with the front wheel of the bicycle.

Below is a concrete example of the execution of a utility model.

The device includes a rack 1 fixed in a vertical direction and mounted on a support surface, carrying a node for fixing the front wheel of the bicycle (Fig. 1).

The rack 1 is made in the form of a vertically oriented elongated profile, for example, a rectangular profile in cross section (from aluminum or from aluminum-containing alloys, steel can be used). On the back side, the rack is equipped with elements 2 used for two-point (at least) fastening of the rack 1, for example, on a car body. The position of the mounting points on the car body depends on the shape of the rear of the car. The stand can be attached both vertically and in a vertical direction, for example, at a certain angle towards the hood of the car. The type and type of attachment and design of the elements 2 is not central to the claimed invention. Currently, there are a large number of structurally diverse elements that allow fixing various accessories on the car body from the trunk to the wings or spoilers.

In the rack 1, guides 3 are made (Fig. 2) for moving along the length of the rack from the lower position to the upper assembly for securing the front wheel of the bicycle. Elastic elements 4 are placed inside the rack cavity, for example, in the form of rubber bands, or tapes, or springs, one end of which is fixed in the upper part of the rack, and with the other ends of which there is a knot for securing the front wheel of the bicycle. In this case, the initial, unstretched or unstretched state of the elastic elements is the location of the node for fixing the front wheel of the bicycle in the upper part of the rack, and when lowering this node to the lower part of the rack, the elastic elements 4 are stretched. In the lower part of the rack, the node for securing the front wheel of the bicycle is fixed from moving upward by the fixing unit relative to the profile, which includes a protrusion or stopper 5 (Fig. 2 and 3), mounted on the profile of the rack 1.

The node for securing the front wheel of the bicycle (Fig. 2) is made in the form of a carriage located in the guides 3 of the profile of the rack 1 with the ability to move along the length of the last and spring-loaded relative to the profile for its forced movement from the lower to the upper position.

The carriage case is made with side stops 6 (to prevent lateral displacement of the front wheel of the bicycle), and in the lower part - with a frame shape with an extension of the type 7 of the sole with a through longitudinal opening 8 for fixing the position of the front wheel of the bicycle. The extension cord 7 is made with a retractable ramp 9 for rolling up the bicycle wheel to this extension (Fig. 5 and 6).

Since the stand 1 is attached to the car body and its lower end is located at some distance from the ground (not lower than the clearance), for the convenience of rolling the bicycle wheel, the user lowers the ramp 9, rolls the wheel onto it and pushes it to the extension 7 of the carriage. At an extension of 7, the wheel fits into a longitudinal opening 8 (due to the rounded outer surface of the tire), where, while recessed, it is fixed from rollback and lateral displacements (side stops 6 work).

In the housing, the carriage is mounted longitudinally in height of the carriage plate 10 or plate element. This plate 10 is pivotally mounted with the possibility of swinging on the axis 11, mounted in the carriage housing. Thus, the plate is a two-arm lever. Two angular two-arm levers are mounted in the upper part of the carriage, the first shoulders 12 of which are located across the carriage body and in the space (at a distance) between the carriage body and the upper end of the plate 10. The other shoulders 13 of the angular levers equipped with stops 14 are located on the sides of the upper end of the plate 10 and protrude forward (perpendicular to the plate 10) from the plate 10 and at a distance relative to each other to form a gap for introducing between them the front wheel of the bicycle. When the plate 10 is rotated towards the shoulders 12, then it puts pressure on these shoulders and puts them in the direction of the carriage body or the profile of the rack. The other shoulders 13 of the angular levers while moving towards each other. When the front wheel starts to elongate 7, it begins to put pressure on the upper part of the plate 10 and turns it in the direction of exerting pressure on the shoulders 12. At the same time, the other shoulders 13 begin to close and are fixed on the tire or rim of the front wheel of the bicycle. Thus, the bicycle wheel is fixed in the carriage (Fig. 3 and 4).

At the bottom of the rack, a stopper 5 or protrusion is fixed, which is used to lock the carriage in its lower position on the rack 1 (Fig. 1). This stopper is a part of the carriage fixation unit relative to the profile of the rack 1. This assembly includes a latch, which is an elongated roller or bracket mounted freely on an axis on the plate 10 in its lower part with a possibility of swinging and spring-loaded towards the plate 10 so that in the lower position of the carriage, the plate 10 is pressed with the lower end to the carriage body (the upper end of the plate 10 is in the position taken away from the shoulders 12) and the bracket enters beyond the protrusion 5 by means of it being preloaded by the springs. When pressure is applied to the upper end of the plate 10, the lower end is angularly displaced, causing the bracket to disengage from the stop 5. The stop 5, as a protrusion, has inclined faces, which makes it possible to approximate the lower end when the upper end of the plate is withdrawn from shoulders 13. end and allow the bracket along the inclined edge to fall into the cavity of the stopper 5. Therefore, when moving the carriage down, the carriage is automatically fixed from movements in the lower position on the rack.

In the lower position on the rack 1, the carriage is additionally fixed. This additional fixation is carried out by the brake assembly. This brake unit is also used to secure against movement of the carriage in the upper position on the rack when securing the bicycle in an upright position.

The following is an example of a brake assembly. The plate in the upper part is equipped with a two-arm lever pivotally mounted on it, one shoulder 15 of which is equipped with means of 16 contact interaction with the strut profile for locking the carriage from moving along the profile, and the other shoulder 17 is elongated and located in front of the upper end of the plate 10. When setting the front wheel in the carriage, the user presses on the shoulder 17 with the tire of this wheel, forcing him to move around the axis of his swing towards the upper end of the plate 10. Shoulder 15 with a contact interaction element (re zin pad or brake shoe), turning, moves away from the surface of the rack profile and releases the carriage. When removing the wheel when removing the bike from the rack, the wheel moves away from the shoulder 17, which, under the action of its own spring, returns the other shoulder 15 to the position of its pressing against the surface of the profile of the rack 1.

In the lower part, the rack is equipped with or made with a support platform (shoe) 18, which is used as a lodgement for placing the carriage and as a support under the rear wheel of the bicycle when the carriage is located in the upper part of the rack 1.

The device of the present invention is used as follows.

The user attaches the rack 1 with the carriage placed on it to, for example, the rear of the car in any way that allows the rack to be securely fixed and to prevent its breakdown while the car is moving. The lower end of the rack 1 is strengthened at a distance from the road, no less than the clearance of the car.

The initial position of the carriage is either in the upper part of the rack 1 or in the lower part of the rack 1. If the carriage is in the upper part of the rack 1, it is necessary to unlock it on the profile by pressing the elongated shoulder 17 of the brake assembly and force the carriage to the lower position (stretching the elastic elements 4) until it clicks on the stopper 5. If the carriage is in the lower position (at the bottom of the rack 1), then it is ready to receive the front wheel of the bicycle.

The user brings the bike to the rack, lowers the ramp 9, and rolls the front wheel into the carriage until it fits into the opening 8 on the lower extension 7 of the carriage. In this case, the front wheel of the bicycle presses on the upper part of the plate 10, which, turning, exerts pressure on the shoulders 12 of the angular levers, which leads to the closure of the other shoulders 13 of these levers, capturing the tire or wheel rim. In this case, due to the rotation of the plate 10, the lower end of the plate is released and it is released from engagement with the stopper 5. With further pressure on the front wheel towards the profile of the strut 1, the tire presses on the elongated shoulder 17 of the lever of the brake assembly, which unlocks the carriage with rack profile 1. Under the action of the elastic elements 4, the carriage begins to rise along with the front wheel of the bicycle.

The user pulls up the rear wheel as the bike exits into a vertically oriented position. The rear wheel fits into the shoe rack. This happens as long as the user does not roll the rear wheel of the bicycle into the shoe of the rack 1. At this moment, the front wheel moves away under the weight of the bicycle from the elongated shoulder 17 of the brake assembly and this shoulder is returned to its original position by the action of the spring, in which the second shoulder 15 of this the lever will rotate in the direction of contact with the profile of the rack 1. The carriage is locked, and its movement under the action of the elastic elements 4 stops.

Removing the bike from the rack is as follows. The user presses on the front wheel of the bicycle and presses the elongated shoulder 17 to the plate 10. There is a release of the carriage relative to the rack. The user pulls the bike towards himself and lowers it, while the carriage moves towards the rack shoe. First, the rear wheel is removed from the shoe of the rack, and then the bicycle is deployed as it moves down in the horizontal direction. In the lower position of the carriage, the user slightly biases the front wheel towards himself, which leads to the release of the upper end of the plate 10, as a result of which the arms of the angular levers diverge to the sides. Upon release, the plate rotates, and its lower end is blocked by a bracket on the stopper 5 under the action of the springs of this bracket. The bike is completely removed from the carriage.

This utility model is industrially applicable and can be manufactured using standard technologies of metalworking and mechanical engineering. The utility model allows you to reliably transport and store the bike in a suspended position. At the same time, the utility model allows the bicycle to be mounted on a car or in another place by a user of any height and any physical capabilities due to the fastening of the front wheel when the bicycle is horizontal and lifted by elastic means.
