Description

[0001]
[Industrial application fields]
The present invention relates to a bicycle display stand for displaying bicycles at a store.
[0002]
[Prior art]
Conventionally, as this type of bicycle display stand, a bicycle can be displayed even in a relatively small space by supporting the bicycle upright on the floor surface with the front wheels facing upward. A display stand is known (see, for example, Patent Document 1).
[0003]
In addition, there is also one in which a plurality of bicycles are placed in a multistage shape so as to increase the utilization of space (for example, see Patent Document 2).

[0005]
However, the former is only the use of the space up to the position of the eye level, and there is a limitation in the utilization of the space, and the latter is advantageous because it can be used up to a position higher than the former. Although there are two at a position higher than the floor surface, the lower mounting member only touches the rear wheel to the floor surface and supports the front wheel diagonally upward, and can only be displayed in two stages. In any case, this type of conventional bicycle display stand mainly focuses on arranging bicycles efficiently, and it takes time to put in and out the bicycle placed on the upper stage.

DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1 to 3 are a front view, a side view, and a plan view showing an embodiment of the bicycle display stand of the present invention in an assembled state, and FIGS. FIG. 7 is a view showing a state in which this bicycle display stand is deformed into a rhombus in plan view.
[0012]
The bicycle display stand shown in FIGS. 1 to 3 includes three main parts, that is, a pair of left and right side frames (1) that form a pillar structure part shown in FIG. 4 and a wheel mounting part shown in FIG. (2) and the footrest part (3) shown in FIG.
[0013]
The side frame (1) has a plurality of (four in the illustrated example) steel pipe columns (4) whose height is gradually increased from the front (right side in FIG. 4) to the rear (left side in FIG. 4). These struts (4) are connected by a bottom connecting member (5) and an intermediate connecting member (6) close to the top, for example, by welding. As shown in FIGS. 1 and 3, the side frames (7) are arranged such that a pair is separated from the left and right. Casters (12) are attached to the lower surfaces of the front and rear ends of the bottom connecting member (5).
[0014]
The wheel mounting portion (2) is attached by insertion between the tops of the equal height struts (4) opposed to the left and right. As shown in FIG. 5, the distance between the equal height struts (4) is as shown in FIG. A front wheel mounting member (8) is provided on one end of the horizontal rod (7) having an appropriate length, and a rear wheel mounting member (9) is also provided on the other end.
[0015]
The steel rod (7) is preferably a steel material having a square cross section, and both ends thereof extend in a vertical direction, that is, a direction perpendicular to the horizontal rod (7), and are a relatively short length of a tubular body (insertion portion) ( It is welded to 10). The cylindrical body (10) is a steel pipe having an inner diameter slightly larger than the outer diameter of the steel pipe constituting the support (4), and the upper end of the support (4) is inserted here. Alternatively, a cylindrical body having an outer diameter slightly smaller than the inner diameter of the column (4) may be connected to the lower end of the cylinder (10) and inserted from the upper end of the column (4). The front wheel mounting member (8) or the rear wheel mounting member (9) described above is welded to the upper end of the cylindrical body (10) to form a wheel receiving portion (11) as a whole.
[0016]
Wheel stopper pieces (13) made of steel wire bent in a semicircular shape obliquely upward and outward are welded to the left and right ends of the front wheel mounting member (8). In addition, a pair of wheel side-fall prevention members (14) made of steel wire bent in a large trapezoidal shape are attached to the front and rear sides of the rear wheel mounting member (9) so that the upper part reaches the vicinity of the wheel axle. It has been.
[0017]
The footrest portion (3) shown in FIG. 6 is mainly composed of a rectangular steel plate (15) whose rigidity is increased by bending the front and rear end portions downward. A pair of front and rear L-shaped steel pieces (16), (16) extending in the left-right direction is applied to the side surface of the horizontal cross-section (7) having the above-mentioned square cross section. They are fixed by welding so as to face each other with a contact interval. A bolt hole (17) is drilled at the lower part of the steel slab (16) at a position in contact with the lower surface of the horizontal bar (7). It can be concluded. As shown in FIG. 1, such fastening sites are provided at three locations.
[0018]
When assembling the bicycle display stand of the present invention, first, a pair of side frames (1) are set up at an interval in the left-right direction, and wheels are placed on the tops of the two equal-level support columns (4). The cylindrical body (10) of the part (2) is fitted and attached.
[0019]
Next, the foot rest part (3) is inserted into the bolt hole (17) by fitting the pair of L-shaped steel pieces (16) into the horizontal cross section (7) of the cross section of the wheel rest part (2). The bolt (18) is inserted, and the wing nut (19) is tightened to fix it to the reed (7).
[0020]
The side frame (1) and the wheel mounting part (2) can be attached only by inserting the cylindrical body (10) having a larger diameter into the small diameter column (4). The angle that the wheel mounting portion (2) forms in a plane is not limited to 90 degrees, and can be set or changed to any desired angle as shown in FIG.
[0021]
In addition, although the support | pillar (4) was mentioned above as a thing made from a steel pipe, it is enough if the upper end part of a support | pillar (4) is circular in cross section, and shapes other than an upper end part are not restricted to a cross-sectional circle. Moreover, although the cross-sectional shape of the recumbent rod (7) has been described as a quadrangle, it is not limited to a quadrilateral as long as the bolt (18) penetrates the recumbent rod (7).
[0022]
【The invention's effect】
According to the first aspect of the present invention, it is possible to enhance the display effect by displaying the bicycle in a tandem shape with a simple configuration.
In addition, it is possible to climb on each step by using the footrest part, and the upper bicycle can be easily taken in and out.
[0023]
According to the second aspect of the invention, assembly and disassembly are extremely easy, and the display position can be easily set and changed.
[0024]
According to the invention described in claim 3, the bicycle display stand can be deformed into a rhombus in plan view, so that the front and rear bicycles can be shifted to the left and right for display, and the display effect can be further enhanced. .
