Abstract

The utility model discloses a bearing lifting system, which is provided with an electric height adjusting device and is used for lifting objects to store large daily articles, and a box-type bearing system is formed by two parallel and spaced ball bearing telescopic guide rails, a bearing disc and a bearing frame for vertical linear guide of cantilever load. For adjusting the height of the cantilever load, an electric traction device is used, which is guided through the center of a box-type carrying system, which is supported on the ground, so that the entire load is guided directly to the ground, and a drawer bracket of the electric traction device is connected to the carrier by means of a traction rail, which drawer bracket is parallel to the central axis of the telescopic rail. For forces which cannot be absorbed by the ball bearing telescopic rail due to off-centre loads acting on the box-type load carrying system, sliding guide shoes are used for guiding, which are fixed to the carrier and support the guide profile of the drawer bracket of the electric traction device.

Description

Bearing lifting system

Technical Field

The utility model relates to a bearing lifting system.

Background

The widespread popularity and use of electric bicycles presents new challenges for parking or using electric bicycles. Parking in basements or garages, maintenance and repair works, especially of electric bicycles, are also related to physical effort. The electric bicycle has an average weight of about 25 kg and requires physical power for transportation on narrow stairs.

Lifting the electric bicycle to an easily accessible working height into the fixed jaws of the assembly station is also very physical and energy intensive.

Note also the 60+ generation. Parking bicycles in a garage is often unsuccessful due to the insufficient depth of the garage. The problem comes from: where is the bicycle well?

In german patent document DE 10 2015 100 603 A1, a retaining device for a bicycle carrier with a trailer hitch adapter is disclosed, which has a retainer attached thereto and form-fitting with a guide rail, and a ball head and height adjustment device connected to the carrier, on which the bicycle carrier can be fixed and lifted to a certain height, so that a free space is formed on the ground.

In the disclosed retaining device DE 10 2015 100 603 A1, the described components and the guides formed thereof have the disadvantage that in all the disclosed embodiments they are combined with an open guide rail (C-type) which is combined with a unit consisting of a bracket, a container and a ball-head coupling, the load on the support bar protruding at right angles is not evenly spread and guided and may get stuck at any time. Resulting in failure of the lifting function. I.e. the reliability is too low. And the guide portion thereof is too short, so that the reliability of the lifting is poor.

Thus, the forces acting on the open guide rail, starting from the cantilever weight of the bicycle carrier with the clamping adapter, including the bicycle (about 80kg in total), after passive absorption, cause the C-profile to expand and deform, thus causing the slide to seize in the guide profile. Meanwhile, the quality distribution of the lifting body is generally uneven, so that lateral torque is necessarily caused, and the phenomenon of clamping or dead clamping is also easy to cause.

In the case of eccentric forces applied to the open guide rail, for example in the case of an asymmetrical weight distribution of the electric bicycle in the bicycle carrier, which additionally generates torques in different directions on the guide system and thus forces, there is also the possibility of insufficient support and jamming of the composite unit of the carriage with the socket in the guide profile.

Another disadvantage of this patent is that the total length of the guiding system is too long. Since it always consists of stroke length plus sliding length, thereby significantly increasing the packaging length. Thereby causing great inconvenience in transportation. Greatly increases the transportation cost and reduces the purchase wish of users.

In order to approximately meet the basic functional requirements of such a device for bicycle carriers with height adjustment devices and also to be able to absorb the stresses occurring in the guide devices, the disclosed guide device DE 10 2015 100 603 A1, the part used for the sliding or rolling device in the X and Y plane, is essentially large and long in order to meet the requirements of the lifting height; and, as suspended from the wall, the rigidity of the just-towed structure must be strong, which can add significant weight and cost to the component.

Furthermore, the known load-bearing lifting system (bicycle retaining device DE 10 2015 100 603 A1) has little or no technical problems of user-friendliness and safety that are considered to be present.

Disclosure of Invention

The object of the present utility model is to provide a universal load-bearing lifting system, which is equipped with a suitable guiding system and uses lifting means with the necessary safety technical equipment, so as to provide a user-friendly storage device not only for bicycles, but also for generally bulky, space-intensive articles of use, winter sports equipment and water sports equipment.

Furthermore, the object of the utility model is to provide a load-bearing lifting system equipped in such a way that a single bicycle, in particular an electric bicycle, can be lifted and fixed to a suitable installation work height with the aid of a quick-change device at a sufficient distance from the wall and without special physical effort and with good operability.

For a generally cost-effective product, the greatest challenge is how to meet the design tasks of each technical performance with optimal production cost, for example, the lifting part of the product reasonably selects standard machine elements in the industrial product, so as to solve each individual design task with low cost to meet the design performances, for example: "guide task", "lifting task", "control task", "operation task", "safety task".

In addition, in order to facilitate the easy installation of the lifting system by the user, the product is almost completely preassembled, or as much as possible, as a preassembled unit is provided before shipment, so that it can be easily installed in a garage or other storage space of the user as long as the user has general skills or is well equipped with a DIY fan.

For this purpose, the sub-components (assemblies) of the load-bearing lifting system of the utility model should also meet the specifications of the transport service provider, such as express, in terms of size, weight and packaging. The length of the rail does not affect the maximum package length of the load bearing elevator system.

An important aspect of the utility model is for the purpose of optimizing the electric traction means and the guiding system of the load-bearing lifting system in such a way that the electric traction means are combined with the guiding system of the load-bearing lifting system in such a way that the cantilever load and the associated leverage of the load to be lifted only causes low friction in the electric traction means, so that no or only additional traction from the electric traction means is required.

Furthermore, the moment of action in the load bearing lifting system at an angle of 90 ° to the cantilever load is an eccentrically arranged load, for example in the load bearing plate, or in the mounting bracket, clamping the bicycle, which should be supported and acted upon without having a greater influence on the performance of the electric traction device, which is to be achieved by the load bearing lifting system of the utility model.

In accordance with another aspect of the utility model, the structural dimensions of the load bearing lifting system on a wall (e.g., a garage) should be kept as small as possible to minimize the occupation, or impact, of the depth of the garage.

We observe the guiding system about 100mm from the ground. The spacing between the bicycle carrier and the bicycle carrier depends on the bicycle handlebar size. The size of the handle bar determines the distance of the support platform or tray from the wall.

In the case of a universal load-bearing lifting system for use with a bicycle carrier, it is therefore of great importance to connect the ball-end trailer coupling to the moving part of the guiding system (the carrier), so that in the bicycle carrier the first bicycle and thus the bicycle closest to the wall, a sufficient distance of the handlebars from the wall is ensured.

If a load bearing lift system is used without the use of a ball-end trailer coupling quick change system, other connection means, such as screw and plug connections and suspension means, must also be considered.

This problem is solved by the features. Further advantageous and advantageous embodiments of the utility model are achieved from the dependent claims, the utility model being explained in more detail on the basis of the drawing.

The system function of the bearing lifting system (1) is formed by the traction track (23), wherein the traction track (23) is connected with a driving piece (22) of the drawer bracket (6) of the electric traction device (B) through a driving bolt (24) of the bearing frame (7) and then is connected through a pin of a pin shaft (21).

"control", "operate", "stationary" the load carrying lift system (1), which is one of the global general devices of large electric traction devices (B).

The carrier (7) is connected to the inclined threaded surface of the ball-end trailer coupling (8) at 3 °.

The ball-end trailer coupling (8) has an interface for a commercial bicycle carrier.

The ball head trailer coupling (8) is provided with an interface of a bearing disc or a bearing platform.

The screw, male or hook-in connection means on the carrier form an interface for a rapidly exchangeable bicycle carrier, carrier platform, carrier plate or mounting bracket.

The safety-related operation of the load-bearing lifting system is performed by means of an operating keyboard which sends a time-limited WLAN signal to the control unit by means of a multi-digit PIN input, followed by an ENTER confirmation by means of up-down function data, and the up-down function keys are equipped with unattended functions, which interrupt the corresponding functions when the keys are withdrawn.

Fig. 6 is a cross-sectional view of the box carrier system of fig. 1 taken along line A-A, with the guide of the electric traction device and the guide shoe of the load-bearing lift system supporting in the C-shaped profile of the electric traction device.

Fig. 7 is an enlarged view of a portion of circle 13 of fig. 2, showing relevant details.

The supporting force generated by the lever force of the cantilever load E is absorbed only by the inner rail of the carriage 7 and the two parallel spaced ball bearing telescopic rails 5, by the rolling elements held in the cage and spread out, and transferred to the carrying tray on the outer telescopic rail 4 through the ball grooves of the inner, central and outer telescopic rails.

The thus formed closed box guide system is secured to a wall of a garage or similar available storage compartment by means of a set screw. The forces acting at 90 deg. to the force of the cantilever load, such as the moment of the eccentric load, are mechanically separated by a sliding guide system between the sliding guide shoes 25 and the sliding guide shoes 25, the sliding guide shoes 25 being fastened to the carrier of the box rail by screws and being mechanically separable. The floor-mounted guide profile 20 is supported on the wall by an electric traction device B.

For the task of "guiding" the cantilever load E, the two parallel separate telescopic guides are equipped with ball rolling elements by means of which a maximum extension length can be achieved, similar to the design of a drawer system after full extension.

These telescoping rails are primarily of shelving technology with fully extended heavy duty drawer systems and are capable of withstanding the high loads created by the cantilever loads.

The telescopic design also has the advantage that the fully extended telescopic guide rail, the maximum dimension of the guide rail, is also its maximum stroke length.

In addition, these telescoping rails are used in a large number of shelving technologies in the furniture industry and in mechanical engineering and are therefore a tested and inexpensive universal product.

In order to take advantage of these special characteristics of telescopic rails from the shelving technology in load-bearing lifting systems in lateral applications, the ball bearing telescopic rail 5 has two beams made of aluminium or steel plates, formed by stiffener bending members, the ball bearing telescopic rail 5 being connected to a closed rigid box-type load-bearing system a. For this purpose, the outer telescopic rail of the ball bearing telescopic rail 5 is screwed to the carrier plate 4 and the inner telescopic rail is screwed to the carrier frame 7.

The task of "lifting" the cantilever load E is accomplished by means of an electric chain or electric traction device B, which we refer to and design from the application of garage door openers. The design of these electric traction devices is mainly introduced in the following parts: by means of an electric drive with a self-locking reduction gear, the necessary traction force for opening or closing the revolving door and the roller shutter system is provided, irrespective of the other guiding tasks, without introduction.

In the case of an asymmetric load introduced through the carrier 7, it is necessary to absorb or balance the supporting forces which are not absorbed by the ball bearing telescopic rail 5 elsewhere. The pivot bracket movement parallel to the mounting wall must be supported over the entire length of the rail. According to the utility model, the guide profile 20 of the carriage of the completely independent box sliding system or electric traction device fixed to the wall or ground is fitted with a fixed guide rail, supporting the oscillating carriage for the entire stroke length by means of sliding guide shoes 25 fixed to the carriage 7 of the box-type carrying system a.

If an attachment for quick change mounting support arm H is used, the pivoting 26 of the horizontal support arm creates an eccentric load that is transferred to the carrier 7 by the lock 31 of the catch 30.

The asymmetric load of the bicycle secured to the bicycle frame by the clamping jaw 27 is stabilized by the tube clamping lever to secure the tube twist and the pivoting of the horizontal support arm. This load situation is taken up by the combined guiding system of the box carrier a with the sliding guide shoes supporting the guiding profile of the traction means. Therefore, the application of the sliding guide shoe is one of the advantages of the design.

The pulling device of the garage door opener system provided by the utility model also solves the tasks of control, operation and fixation. These garage door opener systems include a series of tested motor controls, a freely programmable end position closing switch, an overload detection, a WLAN operation for the start and stop functions of the lift and/or stop functions.

The use of self-locking gearboxes in motion and in the drive train ensures safety and reduces accidents. In order to prevent unintentional operation and automatic up-and-down movement, multi-digit PIN protection is also provided by a manual transmitter, and an unattended function is provided in the up-and-down buttons to ensure personal safety.

The load bearing lifting system of the present utility model thus solves the cost-related and safety-related tasks. According to the utility model, these two main components, a closed box-type carrying system a and an electric traction device B, are to be combined together to form a carrying lift system 1. For this purpose, the bracket of the chain traction bracket 22 must be connected to the bracket bolt 24 of the bracket by means of a pin shaft with a pin lock 21, by means of a traction track 23.

In order to facilitate easy installation of the load bearing lifting system 1 by a user, the convenience of installation is considered in advance, and optimization and user-friendly design are performed, so that no special professional is required for installation and initial debugging.

First, the preassembled box-carrying system a must be fastened vertically to a wall at a distance of about 150mm above the floor of the room (garage) with several positioning bolts 18.

Secondly, the electric plug-in, two-piece preassembled electric traction device B must be guided through the centre of the box carrier system a and also fixed to the wall by means of the mounting bracket 3 using 2 set screws 17 and on the ground above the support bracket 12 of the swivel bearing.

These two main parts a and B must then be mechanically connected to the drawbar 22 by means of two pins with pin protection 21 to fulfill their function. Finally, the ball-end trailer coupling 8 is screwed onto the carrier 7, which forms an interface for quick-change carriers, such as a bicycle carrier C for trailer hitching.

This means that the load hoisting system 1 is fully assembled and that initial commissioning can be performed by end position programming. Connection to electrical energy is achieved by connecting the SCHUKO connector (euro plug) with the electric traction means B of the integrated electronic device 2 to the nearest socket.

Other carriers with carrier plates or carrier trays suitable for use with the ball-end trailer hitch 8 having a clamping mechanism 16 may also be combined with the carrier lift system 1 to lift and store a fixed load.

This results in a device with which, for example, an electric bicycle can be lifted to a height of 1.0 to 1.2 meters on a cantilever storage and fixing device, and the space under the storage device remains free to accommodate the front part of the vehicle, i.e. to facilitate parking of the vehicle.

If provided with a quick-change mounting support arm (H in the drawings), lifting and fixing the bicycle or electric bicycle to different working heights, maintenance and repair work is also very convenient, very easy and does not require a great deal of physical effort. Time is saved, and operation is convenient.

The present utility model is not limited to the above embodiments, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the scope of the present utility model, and these modifications and substitutions are intended to be included in the scope of the present utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
