Description

Technical Field

[0001] The present invention relates to the technical field of roller skates, and in particular to a roller skate rack. Background Art

[0002] Roller skates are shoes that are combined with a roller skate frame for easy skating. Common roller skates and the shoe frame are mostly fixed structures that are integrated and the shoe frame cannot be folded. Users can only use the shoes for skating. If they use the roller skates for normal walking, they are prone to falling. Therefore, when walking normally, users need to replace the roller skates with ordinary shoes, which is very inconvenient. Summary of the Invention

[0003] The present invention overcomes the deficiencies of the prior art and proposes a roller skate shoe rack that meets the needs of users and can achieve both gliding and normal walking functions without changing shoes.

[0005] Furthermore, the control link includes a center plate connected to the rotating rod, the left end of the center plate is hinged to link one, the right end is hinged to link two, link one is hinged to the left control limiting component, and link two is hinged to the right control limiting component.

[0006] Furthermore, each of the supporting short pieces and supporting long plates is provided with a plurality of weight-reducing holes.

[0007] Furthermore, there are four control and limiting components, one end of which acts on the linkage shaft 1 and the linkage shaft 2, and the other end is connected to the frame through a compression spring.

[0008] The beneficial effects of the present invention are:

[0009] 1. The present invention can meet the different needs of users, that is, it can realize both sliding and normal walking functions without changing shoes;

[0010] 2. The present invention sets a foldable pulley assembly in the frame and uses a limit assembly to limit the pulley assembly, so that the user can unfold the pulley assembly to achieve the purpose of sliding when in use, and fold the pulley assembly to achieve the purpose of normal walking.

The linkage shaft 1 3-2 and the linkage shaft 2 3-5 are connected by a linkage piece 3-7, which is set outside the frame 1. The two ends of the linkage shaft 2 3-5 are also connected to the frame 1 through tension springs 3-6;

[0030] Each limiting assembly 4 includes two control limiting members 4-1, and the two control limiting members 4-1 are symmetrically arranged on the front and rear sides of the frame 1. The rear end of each control limiting member 4-1 is provided with a compression spring 4-2, and the other end of the compression spring 4-2 is connected to the frame 1; that is, there are a total of 4 control limiting members 4-1, one end of the control limiting member 4-1 acts on the linkage shaft 1 3-2 and the linkage shaft 2 3-5, and the other end is connected to the frame 1 through the compression spring 4-2, and the control limiting member 4-1 at the left end and the control limiting member 4-1 at the right end of the same side are connected by a control link 4-3, and the two control links 4-3 are connected by a rotating rod 4-4, and one end of the rotating rod 4-4 is provided with a knob 5, which is arranged outside the frame 1, with reference to FIG.

[0031] refer to Figure 11 and Figure 12 In order to make it easier to use, each supporting short piece 3-1 and supporting long plate 3-4 is provided with a plurality of weight-reducing holes 6 to reduce the weight of the entire shoe rack.

[0032] refer to Figure 13 The frame of the roller skate rack can also be made into an arc-shaped structure at both ends.

[0033] The roller skate shoe frame of the present invention is used to be installed on the bottom of the shoe. When the roller skating function is needed, the pulley 3-3 component is unfolded to extend from the frame 1 for roller skating. When the roller skating function is not needed for normal walking, the pulley 3-3 component is folded and hidden in the frame 1 for normal walking.

[0034] The specific folding and unfolding principle of the pulley 3-3 assembly is as follows:

[0035] As shown in the figure, when you want to fold the pulley 3-3 assembly into the frame 1, rotate the knob 5 to activate the control link 4-3, and the control link 4-3 drives the control limit member 4-1 to move, that is, the center plate 4-32 of the control link 4-3 rotates, and the link 1 4-31 and the link 2 4-33 move inward relative to each other. Driven by the link 1 4-31 and the link 2 4-33, the control limit member 4-1 on the left moves to the right, and the control limit member 4-1 on the right moves to the left. After moving a certain distance, the control limit member 4-1 no longer blocks the linkage shaft 1 3-2 and the linkage shaft 2 3-5. At this time, the compression spring 4-2 is in a compressed state; then the user pushes the pulley 3-3 upward with his hand, and the pulley 3-3 drives the supporting short piece When the pulley 3-3 is in the upright position, the pulley 3-4 is in the upright position, and the pulley 3-3 is in the upright position, so that the pulley 3-3 ...

[0036] If you want to unfold the pulley 3-3 assembly from the folded state, turn the knob 5 again to control the action of the connecting rod 4-3, control the movement of the limiting component 4-1 to lose the limit on the linkage shaft 1 3-2 and the linkage shaft 2, and the linkage shaft 2 3-5 moves downward under the action of the tension spring 3-6. The linkage shaft 1 3-2 moves simultaneously with the linkage shaft 2 3-5 through the linkage piece 3-7. At this time, the pulley 3-3 assembly is unfolded in the frame 1. After loosening the knob 5, the control connecting rod 4-3 moves outward under the action of the compression spring 4-2, and the linkage shaft 1 3-2 and the linkage shaft 2 3-5 are stuck in the lower part of the slide groove. At this time, the pulley 3-3 is in the unfolded state.

[0037] The above-mentioned specific embodiments are merely specific examples of the present invention and are not intended to limit the present invention in any other form. Any person skilled in the art may utilize the above-mentioned technical content to modify or modify the above-mentioned embodiments into equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above-mentioned embodiments based on the technical essence of the present invention, without departing from the technical principles of the present invention, shall fall within the scope of patent protection of the present invention.
