Abstract

The utility model discloses a novel balance beam. In addition to a crosspiece and a support post, the novel balance beam further comprises a buffer structure. The upper surface of the crosspiece is a horizontal surface, and two side surfaces of the crosspiece protrude in a drum shape. The support post is made of metal, and the support post is fixed on the lower part of the crosspiece. The buffer structure is made of rubber or plastic. The thickness of the buffer structure is 0.1mm to 2mm. If the thickness is less than 0.1mm, the buffer structure is not capable of playing a role of buffering. If the thickness is greater than 2mm, the buffer structure affects the stability of an athlete. The buffer structure evenly covers the upper surface and the side surfaces of the crosspiece with adhesives. The total width of the crosspiece and the buffer structure is 10cm. The novel balance beam provided by the utility model has the advantages of simple structure and easy manufacture, and is suitable for all of balance beams.

Description

Novel balance beam

Technical field the utility model relates to a kind of balance beam, especially has the balance beam of buffer structure.

The background technology balance beam is the indispensable equipment of balance beam match in the women's gymnastics.Balance beam generally is made up of beam and support column, and wherein, beam is by the timber manufacturing, and the upper surface of beam is a horizontal plane, and it is outstanding that two sides of beam are drum type; Support column is by made, and support column is fixed on the bottom of beam.Balance beam is square batten, long 5 meters, and wide 10 centimetres, high 1.20 meters apart from ground.But, this structure of current balance beam, security still is poor.The sportsman is in training and competition, and action can cause actual bodily harm accidentally.

Chinese patent CN201079650 number disclosed " a kind of liftable balance beam " patent (application number: 200720156838.5); Make a platform with the soft fabric of timber; Be embedded with liftable balance beam in the middle of the platform; The two ends of balance beam have the movable headblock that polylith can add, subtract, and the plus-minus headblock is the up-down of adjustable and balancing wood just.The height of adjustment wood cooperates with the voice by-pass cock, just can realize the function of various games, teaching conversion.Chinese patent CN201223665 number disclosed " steel-wood structure balance beam " patent (application number: 200820077239.9); Beam comprises channel-section steel and mounting plate; The last plane of mounting plate and the lower surface of channel-section steel are welded to connect, the following installation bottom plate of mounting plate, and the upper end of the lower plane of bottom plate and column and diagonal brace is welded to connect; The lower end of diagonal brace and the side of column are welded to connect, and dismountable plate shape device is installed in the outside of described channel-section steel.The weak point of these two patents is: though reduced the problem of beam distortion, still can not in the balance beam training and competition, increase security.

In addition, do not retrieve the documents and materials more approaching with this patent.

The purpose of summary of the invention the utility model is exactly that a kind of novel balance beam simple in structure will be provided, and increases the security of balance beam training and competition.

In order to achieve the above object, the novel balance beam that the utility model provides also has buffer structure except having beam and support column, and wherein, the upper surface of beam is a horizontal plane, and it is outstanding that two sides of beam are drum type; Support column is by made, and support column is fixed on the bottom of beam; Buffer structure is by rubber or plastics manufacturing; Buffer structure thickness is 0.1 millimeter～2 millimeters, and thickness is lower than 0.1 millimeter just not competent cushioning effect that plays, and thickness then influences athletic stability greater than 2 millimeters; Buffer structure evenly covers the upper surface and the side of beam through bonding agent; Beam is 10 centimetres with the overall width of buffering structure.When the utility model used, buffer structure increased the adhesive force of sportsman's sole when not influencing sportsman stability, also can be when meeting accident the contact impact power of kicking motion person's health and beam, the security of increase balance beam training and competition.

The novel balance beam that the utility model provides has positive effect: have outside beam and the support column, also have buffer structure, wherein; Buffer structure is by rubber or plastics manufacturing, and buffer structure thickness is 0.1 millimeter～2 millimeters; Buffer structure evenly covers the upper surface and the side of beam through bonding agent, and beam is 10 centimetres with the overall width of buffering structure, and is simple in structure; Easy to manufacture, be suitable for all balance beams.

Description of drawings the utility model will combine accompanying drawing to be further described, please referring to accompanying drawing:

The sketch map of accompanying drawing 1 expression the utility model.

Structure shown in the accompanying drawing 1 comprises: buffer structure 1, beam 2, support column 3.

The novel balance beam that specific embodiment the utility model provides also has buffer structure 1 except having beam 2 and support column 3, wherein, the upper surface of beam 2 is a horizontal plane, and it is outstanding that two sides of beam 2 are drum type; Support column 3 is by made, and support column 3 is fixed on the bottom of beam 2; Buffer structure 1 is by rubber or plastics manufacturing; Buffer structure 1 thickness is 0.1 millimeter～2 millimeters, and thickness is lower than 0.1 millimeter just not competent cushioning effect that plays, and thickness then influences athletic stability greater than 2 millimeters; Buffer structure 1 evenly covers the upper surface and the side of beam 2 through bonding agent; Beam 2 is 10 centimetres with the overall width of buffering structure 1.When the utility model uses; Buffer structure 1 is not when influencing sportsman's stability; Increase the adhesive force of sportsman's sole, also can be when meeting accident the contact impact power of kicking motion person's health and beam 2, the security of increase balance beam training and competition.

The utility model protection domain relates to all changes form recited above.

Claims
