CN2707330Y - Shockproof ice skate with straightly arranged rollers - Google Patents

Abstract

The utility model discloses a shockproof ice skate with straightly arranged rollers comprising a frame, a shoe shell and a shoe sole. The utility model is characterized in that the frame adopts an arch bridge type structure with the arch top connected with the flat top frame. The structure increases the space of the front end of the frame. The utility model cancels the prior crossbeam between the front end and the back end of the frame. The entire structure has the advantages of the elasticity of the U-shaped component also the firmness of the triangle component. The diameter of the wheel can be further enlarged by the front structure of the frame under the condition of invariable height between the front part of the shoes and the ground. Due to releasing the prior resistance of the prior right angle type structure, thereby, the frame possesses more strong shock resistance. The frame can avoid the impact, the harmful effect to the skater body is overcome, and both the safety and the service life are improved.

Description

A kind of antidetonation straight-line roller skates

Technical field

The utility model relates to roller skates, and particularly roller is the ice skate of single-row straight-line.

Background technology

The ice skate (below abbreviate the straight-line ice skate as) that roller is single-row straight-line are to be transformed by the single-blade ice skate of usefulness on ice.So because simple in structure, any ground can both be used, existing so far hundreds of different designs sutable for men, women, and children.For example, for braking, just there are between toe brake type, heel brake type, wheel brake type, hand control dynamic formula, electric control dynamic formula etc. multiple.For the form of roller, there just have that single-row ball bearing formula, double row ball bearing formula, narrow tire formula, wide tire formula, smooth hard tire formula, chrysanthemum tyre surface formula, wheel shaft are parallel to ground type, wheel shaft is not parallel to ground type etc. to be multiple.For the layout of roller, but just have all fixed, all can be telescopic up and down, grouping is swing, partly can be telescopic up and down, all axial stretching formulas etc. several.For the footwear body, just dividing must be with special footwear and must be with two kinds in special footwear.Therefore, to discuss as an example in the utility model be need the fancy shoes body in the straight-line ice skate, that the roller position is all fixing, wheel shaft be parallel to ground, the brake type the sort of inline skate of heel, for example at [1] CN 99211734, [2] CN 01208942, [3] US5839736, [4] DE 20105061 U1, public affairs are opened in the patents such as [5] JP 07-18506.

The characteristics and the shortcoming of this inline skate are:

(1) a plurality of rollers that are arranged in a linear all are to be fixed in framework, can not stretch up and down, and wheel shaft all is parallel to ground.Framework is a structure of right angle tyoe, constitute to two-layer crossbeam by one deck flat-top frame and, the structure of one deck crossbeam is the most weak, though and the structure of two-layer crossbeam has reinforcement, but its weight is heavier, and compressed end spaces before the framework, wheel diameter is dwindled, the shockproof effect of this kind structure of right angle tyoe framework is poor, when especially front-wheel knocks the ground ridge, not only framework is subjected to the destruction that huge impact can cause framework, and is in when standing erectly posture as the skater, and this vibrations also can be delivered to brain by heel always.

(2) framework that roller is housed is pressed on the base plate by frictional force with a plurality of flanges and screw, promptly there is no the measure that relatively moves of preventing between framework and the base plate.Example [3] disclosed structure when assembling in order to make the frame alignment base plate, tighten screw again after utilizing this point that both are aimed at just.Unfortunately when ice skate use, to hit stress that attack or control action produce the first time that front-wheel suffers and will make the framework and the temporary transient or even permanent displacement of base plate generation of having aimed at, the technology that causes influencing the skater is brought into play and security.

Summary of the invention

For solving above-mentioned prior art problems, the purpose of this utility model provides a kind of antidetonation straight-line roller skates, and its shock resistance is strong, and long service life and security performance improve greatly.

The purpose of this utility model is achieved in that a kind of antidetonation straight-line roller skates, comprises framework, footwear shell and sole, it is characterized in that: the arch-type structure that the arch top that described framework adopts increases the preceding end spaces of framework is connected with the flat-top frame.

The utility model has been cancelled the crossbeam of prior art at the framework front and back ends, the elasticity of the existing U-shaped member of total, the steadiness that triangle component is arranged again, its framework front-end architecture is under the constant situation of the half sole terrain clearance of footwear, can further increase wheel diameter, and because the stress of the prior art structure of right angle tyoe of having releived, therefore make framework have stronger shock resistance, not only avoided framework to be subjected to the destruction of collision deformation, more make the skater avoid shaking harmful effect, improved security performance and service life human body.

The specific embodiment

The utility model comprises framework 11, lower casing 12, sole 14 and footwear body etc., and Fig. 1 has shown the position relation between them.For the sake of brevity and irrelevant each of the utility model brake at heel position etc. for example partly, in Fig. 1, do not demonstrated.

Framework 11 has adopted the space that makes the framework front end to increase and make the arch-type structure of damping capaicty enhancing, and framework 11 preceding structure can be by clear seeing among Fig. 3 and Fig. 4.In the utility model, no matter be the front end or the rear end of framework 11, all adopted respectively forward and the inverted U-shaped 31 that recedes and extend out, the crossbeam that has replaced prior art, this inverted U-shaped structure 31 at the top and 32 3 reinforcements in the outside and a flat-top frame be connected, form an existing U-shaped structural elasticity, the structural entity that the triangular structure steadiness is arranged again, the space of framework 11 front-end and back-end is increased, and the stress of the prior art structure of right angle tyoe of having releived greatly, strengthened the damping capaicty of framework 11.Flat-top frame 32 is provided with installing hole 34, be fixed in lower casing 12 bottoms (as shown in Figure 2) by flange and screw, flat-top frame 32 is divided into forward and backward two parts, back flat-top frame 32 is a little more than preceding flat-top frame 32, during installation and the groove fit of lower casing 12 bottoms use, promptly constituted and prevented to produce between framework 11 and the lower casing 12 device that relatively moves, the security performance that raising is used.The bottom outside of framework 11 evenly is provided with several fixedly locating holes 33 of wheel wheel shaft, because inverted U-shaped member 31 increases the space of framework 11 front ends, therefore under the constant situation of the half sole terrain clearance of footwear, the diameter of wheel 15 can be increased, improve security performance (wheel is big more, and is skating shoe good more by performance).Selecting for use of framework 11 materials belongs to prior art, and the material of arch bridge structure of the present utility model can not limit this.Because the existing technology that framework 11 can adopt alloy aluminum or alloys magnesium die casting to form, thus adopt structural design of the present utility model can not increase manufacturing cost, but improved greatly security performance and service life.
