Abstract

Disclosed is a ladder with broadened pedal lever, which includes two opposite supporting bars and a plurality of pedal levers, and each pedal lever includes a pipe shaped pedal lever part, an upper pedal segment and a lower pedal segment. The pipe shaped pedal bar part has two locking end parts, each two locking end part has specific length, the upper pedal segment passes through the two locking end parts and inclines backward from the top surface of the pipe shaped pedal lever part and extends upward, the lower pedal segment extends forward with an inverted V-shaped from the upper part of the front side of the pipe shaped pedal lever part, the top surface of the upper pedal segment has the same inclination with the top surface of the lower pedal segment, and is in the same inclined plane, the two locking end parts extend through the two opposite supporting bars, and are fixed with the supporting bar in the out-curled or broaching mode. The utility model has a structure of combined as one body, and the increased pedaling area is convenient for the user to pedal, moreover the structure is simple, and the installation of the spare parts is convenient.

Description

The ladder of treadle broadening

Technical field

The utility model is the ladder of relevant a kind of treadle broadening, and this ladder is equiped with tramples the treadle that area increases.

Background technology

The common metal ladder, especially terraced with the aluminium that the most generally is used, it holds up bar and treadle all with tubular aluminum material for it, and the section of tubular treadle, holding up the width of bar side on the whole to go up for cooperation is square, has the plan square of the trapezoidal of an inclined plane or four corner tool arc chord angles.But no matter use the treadle of aforementioned that a kind of section, because it is size-constrained in the width of holding up the bar side, its area that can be trampled is little, and the stability and the degree of balance that user's both feet are trampled on it are all not good.

The aluminium of No. 86207778 patent case in Taiwan ladder pedal fixed structure has large-area pedal though disclose, but the pedal fixed structure of this prior art fixedly structure of usefulness and the part complexity of use, assembles and during fixed charge, it is high relatively manually to reach material cost.

Summary of the invention

The purpose of this utility model be make tradition treadle commonly used to trample area little, and at the baroque pedal fixed form of aforementioned prior art, and develop simple in structure and can increase the terraced treadle of the broadening of trampling area of treadle.

The purpose of this utility model is achieved in that

A kind of ladder of treadle broadening comprises the two relative bars of holding up and reaches and the plural treadle that is installed in therebetween; Each these treadle comprises again:

One tubular treadle portion, tool two anchors the end, and respectively this two anchors the end, one section length-specific of tool;

One upper footboard section two is anchored between the end by this, and the end face of this tubular treadle portion is toward rear-inclined and extend upward certainly;

Pedal section once, the top of the front side edge of this tubular treadle portion is extended a shape forward like inverted V-shaped certainly;

The end face of the end face of this upper footboard section and this time pedal section has same gradient, and on same inclined plane, and this two anchors the end and stretch into by two and hold up bar relatively, and volume and reaming mode in addition two anchor this end and are fixed to and hold up on the bar.

The utility model has following actively useful effect:

The ladder treadle that area is trampled in increase of the present utility model is the structure of one combination, and trampling area increases, and makes things convenient for the user foot-operated, and simple in structure, and spare and accessory parts are easy for installation.

The specific embodiment

Accompanying drawing number

1. ladder treadle 2. is held up bar

11. 12. times pedal section 13. treadles of upper footboard section

Please refer to Fig. 1, Fig. 2 and shown in Figure 3, the ladder treadle 1 of broadening of the present utility model is essentially the treadle 13 of tool square section, corner on the close back of the end face of treadle 13, toward rear-inclined and extend upward a upper footboard section 11, and leading flank top at treadle 13, extend the following pedal section 12 of a shape forward like inverted V-shaped, the end face of this time pedal section 12 also is an inclined plane, and the inclined plane of the inclined plane of following pedal section 12 and upper footboard section 11, has same gradient, make both end faces of upper footboard section 11 and following pedal section 12, on same inclined plane.

Moreover, can know by Fig. 1 and Fig. 2 and to find out, the both ends of treadle there is no upper footboard section 11 and following pedal section 12 are set, that is this two partly is directly to extend through the two relative bars 2 of holding up respectively, and volume and the mode of reaming directly are fixed to and hold up bar in addition, and therefore, having increases the treadle of trampling area, the mode that just can need not other accessories combines with holding up bar, and forms the ladder with broadening treadle.

In sum, the treadle that area is trampled in increase of the present utility model is the structure of one combination, not only has the advantage that makes things convenient for the user to ride, and does not have the shortcoming of the spare and accessory parts installation inconvenience of common technology complexity, meets the practicality on the industry.And not seeing publication before this creation application, also not public use meets novelty.With this creation and dust head's contrast, can find that it can improve every shortcoming of dust head in addition, have tangible effect and promote that progressive is also unquestionable.This creation accords with the regulation of Patent Law, proposes utility application in accordance with the law.

Above-described embodiment only is in order to this creation being described, making that being familiar with this operator can understand that this creation can reach aforesaid purpose, is not in order to limiting this creation, and the displacement of equivalence element, change etc. generally must be subordinate to the category of this creation.

Claims

1. the ladder of a treadle broadening comprises the two relative bars of holding up and reaches and the plural treadle that is installed in therebetween; It is characterized in that: each these treadle comprises again:

The end face of the end face of this upper footboard section and this time pedal section has same gradient, and on same inclined plane, and this two anchors the end and stretch by two and hold up bar relatively, and volume and reaming mode in addition two anchor this end and are fixed to and hold up on the bar.
