Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further clarified by combining the specific drawings.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a unique embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 and 2, the present invention provides an aluminum-wood pedal, which includes a frame 10 and a bearing plate 20 fixed on an upper surface of the frame 10, wherein the bearing plate 20 includes a fixed plate 21 and a movable plate 22 hinged to one end of the fixed plate 21, a ladder 30 is provided on a lower surface of the frame 10, one end of the ladder 30 is hinged to the frame 10 below an opening side of the corresponding movable plate 22, and a locking assembly is provided at the other end of the ladder 30 for locking and fixing a lower swing end of the ladder 30 to the frame 10; the ladder 30 has a storage position which is parallel to the bearing plate 20 and horizontally arranged in the frame 10, or a working position which forms an included angle with the hinged shaft 11 of the frame 10 around the ladder.

It should be noted that the ladder 30 of the present invention is disposed at an angle with respect to the frame 10 during the specific use, and the size of the angle depends on the distance between the adjacent step structures in the up-down direction of the scaffold and the length of the ladder 30 to be unfolded. Particularly, if the included angle between the ladder 30 and the frame 10 is too small, although the gradient of the ladder 30 is slow, so that the ladder is convenient to climb, the occupied space is too large, and the ladder is not beneficial for a user to climb up from the movable plate 22; the ladder 30 is also not conducive to climbing by a user if it is angled at a large angle with respect to the frame 10. Preferably, the ladder 30 is angled from the frame 10 by an angle of 60 to 75.

The aluminum-wood pedal provided by the invention can be conveniently laid on a scaffold, when the aluminum-wood pedal is used specifically, a user can move between scaffold pedals with adjacent heights through the built-in ladder fixed in the frame 10, the aluminum-wood pedal is simple and convenient, when the aluminum-wood pedal is not used, the ladder can be rotated and the lower hem end of the ladder is fixed on the frame, the space on the scaffold pedals is saved, and the aluminum-wood pedal has a better application prospect.

Further, according to the present invention, the locking assembly, which is used to temporarily fix the lower swing end of the ladder 30 to the frame 10, includes, as a specific embodiment of the locking assembly, a catching bar 31 provided at the upper side of the lower swing end of the ladder 30, a closed catching groove 12 provided at the lower surface of the frame 10; when the ladder 30 rotates around the hinge shaft 11 of the ladder and the frame 10 to the lower hem end to be close to the frame 10, the clamping rod 31 is clamped and fixed in the closing-up-shaped clamping groove 12. Because the shaft of the clamping rod 31 is provided with the arc-shaped surface, the opening of the closing-in-shaped clamping groove 12 can be easily crossed to realize fixation, when the ladder 30 needs to be used, a user can hook the ladder 30 to pull down by utilizing foreign objects, and the shaft of the clamping rod 31 is separated from the closing-in-shaped clamping groove 12, so that the ladder is simple and convenient, the structural design can also avoid the problem that the distance between adjacent scaffold pedals is too large, and the user can not reach the ladder 30 and can easily take down in the standing state.

Further, according to the present invention, in order to prevent the ladder 30 from hitting a user located therebelow when being removed and to provide an additional supporting force when the user climbs the ladder 30, a torsion spring 13 is sleeved on the hinge shaft 11 of the ladder 30 and the frame 10, and the elasticity of the torsion spring 13 is to drive the ladder 30 to rotate to be parallel to the plate surface of the bearing plate 20. Specifically, torsion spring 13 be equipped with two, and establish respectively the cover the both ends of articulated shaft 11, the one end swing arm of this torsion spring 13 supports and leans on the below at frame 10, and the other end swing arm supports and leans on the below at ladder 30, provides ladder 30 around articulated shaft 11 upward swinging's elasticity.

In the invention, the ladder 30 is a telescopic ladder for convenient use and improving the application range of the ladder 30.

According to the invention, in order to facilitate the connection and fixation of the aluminum-wood pedal to the adjacent scaffold pedal structure, the frame 10 is provided at both ends with downward-opening hooks 14 for being clamped and fixed to the rods of the space truss structure of the scaffold. Further, in order to secure the effect of the connection fixing, the hooks 14 are spaced at least two along the end of the frame 10. Specifically, for example, two or three of the hooks 14 are spaced along the end of the frame 10.

The foregoing shows and describes the general principles, essential features, and inventive features of this invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
