Description

2-stage bike rack

The present invention relates to a two-stage bicycle rack, specifically, to improve the problems of the conventional sliding two-stage bicycle rack after sliding out, more structurally simple, easy to manufacture, economical and high convenience, and increased space efficiency It's about a two-speed bike rack.

Recently, the demand for bicycle parking facilities or bicycle racks has increased due to the increase in the population of bicycles and the maintenance of related laws.

In particular, the mandatory provisions of related laws make it mandatory for more than a certain number of bicycle parking facilities to build a new building.

The bicycle is basically parked side by side at regular intervals due to the handle having a constant width, but the number of bicycles that can be parked in a certain space is limited due to the basic width of the handle. For example, 7 bicycles are parked in a space of 3 meters left and right, and 10 bicycles are parked in a space of 4 meters.

Recently, bicycle storages have been installed in parking lots or outdoor areas of apartments, shopping malls, commercial buildings, etc., and efforts have been made to efficiently park as many bicycles as possible in a limited space and double the convenience of use. The situation has been continued for a while.

In particular, recently, in order to increase the space utilization rate, a two-stage bicycle rack that can be placed and stored in two stages up and down is installed.

There have been several embodiments and patent applications for the two-stage bicycle stand for placing the bicycle in two upper and lower stages at the top and the bottom, and the two-stage bicycle stand can be classified into the types of pivot, pull-out and lift. Can be divided into foldable.

The withdrawal ceremony was carried out with an inner case having a cross-sectional channel shape inside the outer case having a cross-sectional channel shape, as in Patent Registration No. 10-0983603, Korean Utility Model Publication No. 20-0445580, and Japanese Utility Model Publication No. 1999-0032614. The roller is driven to slide forward and backward to draw in and out. In the case of the pull-out type, the inner case on which the bicycle is placed is pulled out rearward, and the front and rear widths of the bicycle storage stand are large, requiring a large rear space.

As for the lifting type, as shown in Korean Patent Registration No. 10-0928165 and Utility Model Registration No. 20-0459618, the space on which the bicycle is placed is elevated in the vertical direction from the ground so that the space on the ground is divided into two floors above and below. It is to increase.

On the other hand, the folding is a structure for utilizing the space in non-use by folding the bicycle holder consisting of a plurality of joints and links as in the Utility Model Registration No. 20-0467324.

However, it is pointed out that such a lifting type and folding method has a complicated structure and high manufacturing cost.

The rotating type is arranged so that the fixed or sliding bicycle stand is spaced at regular intervals in the first stage, and then the bicycle is mounted on the second stage by rotating and lowering the two-stage bicycle stand located at the upper part without pulling it backward. It's a bike rack.

Such two-speed bicycle parking lot number is registered Patent No. 10-0919558, Patent No. 10-1119058 and Utility Model No. 20-0451510.

In Patent No. 10-0919558, a pivot table 220 is formed below the two-stage parking table 230 for placing a bicycle and rotated by a plurality of hinges h1 and h2, but the pinholes are formed on the outer circumferential surface of the hinge. After the formation of the 254, the pin 255 elastically actuated by the spring 256 is inserted or released therein so that the two-stage parking lot is kept fixed after the horizontal or the rotation is lowered.

At this time, the operation of the pin is connected to the handle 251 is pulled by a wire 257, the wire 257 is connected to the pin via the pulley.

However, in the case of the two-stage rotating parking lot of this type, the rotational structure is somewhat complicated, and the wires and the handles are required separately. If the wire cable fixed to the handles is loosened, the pins may malfunction.

Patent No. 10-1119058 has a merit that the lower bicycle parking lot can be moved left and right by a roller and a rail structure, and then the upper bicycle parking lot can be rotated up and down on the upper side, so that the space utilization is excellent. There is a disadvantage that the structure of the upper and upper pivot is rather complicated.

Registered Utility Model No. 20-0451510 has a fixed lower parking lot below, and the upper parking lot is staggered at the position avoiding the lower parking lot, and the upper parking lot is rotated as it is. When rotating down, the piston and the projection of the rotation control device functioning as an angle adjusting and locking means may not be coupled correctly and may cause misalignment or malfunction.

In particular, the present invention needs to be compared in more detail with reference to the Utility Model Registration No. 20-0445580 and the Patent Registration No. 10-1119058.

First, in the case of registered utility model No. 20-0445580 (name of the invention: bicycle parking lot value), as shown in FIG. 4 of the patent document, the upper parking unit 300 basically has a main frame 100 and an upper part of the main frame. The main body 310 of the channel shape fixed to the, and the sliding portion of the front and rear from the inside of the main body is made of a seating portion 350 is coupled to the rotating device portion 330 to the front end. In order to park the bicycle, the upper parking unit first slides the seating unit 350 fixedly coupled to the rotation unit front to the rear of the main body 310 to the end as shown in FIGS. 5A and 5B, and then pulls out the seating unit. It is a structure to rotate down.

However, in the case of the upper parking lot of such a structure, the guide rail 311 and the inside of the main body for the smooth operation because it is a structure that slides by sliding into the inner portion of the main body 310, which is basically an outer case having a certain length the bike is raised. The guide roller 313, etc. should be mounted, and the internal structure becomes somewhat complicated due to the need to mount a plurality of rollers 3311 to the rotating device 330 which is integrally coupled with the seating part.

In addition, it is difficult to fabricate because it smoothly and smoothly slides only when dimensional accuracy is maintained between each guide roller and the guide rail formed in the main body and the seating part. In particular, the two-stage bicycle rack is intended to utilize a narrow space, so in the case of the two-stage bicycle rack, the seating unit slides rearward from the inside of the main body so that the length of drawing is relatively long. Space is required.

Patent No. 10-1119058 (name of the invention: two-stage bicycle parking stand) as part of the effort to improve the disadvantages of the registered utility model, without having to withdraw the upper bike holder 230 from the inside of the body as it is Disclosed is a configuration that allows the bicycle to be mounted by rotating downward.

In the case of the registered patent to form an arc-shaped guide groove 222 to the rotary support fixed to the front of the upper bike holder in order to rotate the upper bike holder to lower or return to the stopper pin 260 through A separate rotation control structure is formed on the middle side of the upper bike holder. The rotation manipulation structure is formed on the guide plate 242 'V' shaped guide hole 241, and then formed a handle 243 to move along the guide hole, the handle and the stopper pin 260 It can be seen that the stopper pin is pulled or returned to its original position by the operation of the handle by connecting the wires 250 therebetween.

The structure of the above patent is a complex structure in that the rotating operation structure is formed separately in the rear in addition to the rotating structure of the front, and the manufacturing cost increases, and the tension of the wire connecting the front structure and the rear structure is increased. Looseness is difficult to operate and is expected to be problematic in terms of durability. In addition, from the user's point of view, there is a problem that it is inconvenient and laborious in that it must be lowered and raised up and down in the middle of the upper bike holder rather than the rear end of the upper bike holder.

Therefore, the bicycle should be parked in two levels above and below the ground, but the basic structure of the upper storage rack is simplified to make it easier to manufacture, cheaper to manufacture, less failure rate, and more durable, and further improve the space utilization, and also use from the user's point of view. There is a need to improve its structure to improve convenience.
