Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to an improvement in the structure of a kind of step-type collapsible chair, and more particularly, to the design of a kind of handrail structure, which makes the folding chair itself easy to fold or unfold and provides extremely excellent safety protection measures. The present invention relates to the structure of an articulated folding chair.
[0002]
[Prior art]
At the same time, outdoor leisure activities are universally regarded as important, and many household items also have characteristics such as storage and carrying. To meet the demands of users, the structure of the folding chair in the general market is now universally equipped with a folding and collecting function to facilitate the portable use at the time of leisure.
[0003]
For this reason, the inventor of the present invention also submitted a new invention of application number 89214573, “Bushi-style collapsible chair”, on August 24, 1900, based on his experience in producing multi-year related products. As shown in FIG. 8, the main components of the folding chair (4) include one front leg frame (41), one rear leg frame (42), and two side leg frames (43). The front and rear leg frames (41) and (42) have two crossed and installed front and rear leg rods (411) and (412), respectively, and the two side leg frames (43) each have one. A main rod (431). Also, one connection block (44), one upper rod (432) and one lower rod (433) are pivot-joined. At the same time, the pivot joint block (45) and the front and rear leg frames (41) and (42) are connected to the rod ends of one main side rod (431) and the upper and lower side rods (432) and (433), respectively. The members are linked to each other to be folded or unfolded.
[0004]
[Problems to be solved by the invention]
On the other hand, the above-mentioned folding chair (4) structure can certainly achieve the function of quickly folding and folding, but as shown in FIG. First, it is necessary to always grasp two crossed front leg rods (411) with both hands. In this case, both hands are easily caught between the fore leg rod (411) and the upper rod (432) during the fitting process, and in the worst case, they are injured and safety measures are not excellent. Overall, the reconciliation work is inconvenient.
[0005]
In view of this, the inventor of the present invention has thought of improvement, and in the meantime, through a constant research concept, has devised a kind of "structure improvement of a step-type folding chair," and hopes that this design will achieve the following intent. I do.
[0006]
The purpose of the design of the present invention is to provide an improved structure of a one-stage folding chair. The main ones include one front leg frame, one rear leg frame, and two side leg frames. Among them, one handrail structure is installed on each of the rod bodies of the upper rods of the two side leg frames, and the front sleeve and the rear sleeve are sequentially fixed and installed at appropriate locations on the lower end surfaces thereof. With this design, the folding chair itself can be folded or unfolded quickly and easily when holding or unfolding the folding chair itself with both hands directly on the handrail structure without pinching and damaging both hands. Provide exceptional safety and safeguards.
[0007]
[Means for Solving the Problems]
SUMMARY OF THE INVENTION The present invention relates to an improvement in the structure of a step-type folding chair, which mainly includes one front leg frame, one rear leg frame, and two side leg frames. Among them, one handrail structure is installed on each of the rod bodies of the upper rods of the two side leg frames, and the front sleeve and the rear sleeve are sequentially fixed and installed at appropriate locations on the lower end surfaces thereof. With this design, when the folding chair itself is closed or unfolded, the user can directly hold the handrail structure with both hands, and the folding chair itself can be folded or folded quickly and easily without damaging the both hands. Can be expanded. Overall, it is extremely convenient and practical.
[0008]
[Embodiment of the invention]
In order to clearly explain the features and advantages of the structure of the present invention, the details will be described below with reference to the accompanying drawings.
First, a description will be given with reference to the three-dimensional external view of the stepped folding chair (1) of the present invention in FIG. The main ones include one front leg frame (11), one rear leg frame (12) and two side leg frames (13). Among them, the front and rear leg frames (11) and (12) have front and rear rods (111) and (121) installed in an “X” shape, respectively, while the two side leg frames (13) each have one (1). The main rod (131) is provided, and one connecting block (14) is pivotally connected to one upper rod (132) and one lower rod (133). At the same time, a pivot joint block (15) and front and rear leg frames (11) and (12) are connected to the rod ends of one main side rod (131) and upper and lower side rods (132) and (133), respectively. The members described above are linked with each other, and the folding chair (1) itself is folded or unfolded.
[0009]
This will be described with reference to FIGS. Among them, the handrail structure (2) is installed on the rod body of the upper rod (132) of the two side leg frames (13), and both the upper rod (132) and the handrail structure (2) are provided. The space is fixed by screwing with a fixing piece (21). Further, a front sleeve (22) and a rear sleeve (23) are fixedly installed at appropriate positions on the lower end surface of the handrail structure (2). One through hole (221) is formed inside the front sleeve (22), and one hollow positioning hole (231) is installed inside the rear sleeve (23).
[0010]
Next, a description will be given with reference to FIGS. Due to the structural design of the front sleeve (22) and the rear sleeve (23) below the handrail structure (2) on both sides of the folding chair (1), the support rod (3) can be fixed therethrough. Thus, after installing the chair cover of the folding chair (1) itself, the area stretched between its two opposing support rods (3) provides the user with a very comfortable leg support space. As shown in FIG. 5, two opposing retaining rings (122) are also fixedly mounted on a rear leg rod (121) cross-installed on the rear leg frame (12) to support the support rod ( It is provided for the fixed use of 3), so that the work of collecting the folding chair (1) is advantageous.
[0011]
The features of the design of the present invention will be described with reference to FIGS. When the user combines or unfolds the folding chair (1), the user directly grasps the handrail structure (2) with both hands and quickly and easily interlocks the related members to quickly fold or unfold the folding chair (1). Can be unfolded, effectively improving the disadvantage that the user's hands are easily pinched and injured by the front leg rod (111) and the upper rod (132) when the conventional folding chair (4) is settled. It provides safety measures and also has the function of placing the user's hands on both hands.
[0012]
[Effect of the invention]
As described above, the "structure improvement of the step-type collapsible chair" of the present invention effectively improves the drawback that the conventional step-type collapsible chair can easily catch and injure both hands, and at the same time reduces the work of collecting the collapsible chair. Make it simpler and more convenient. Since the present invention has an unprecedented design, has excellent practicality and inventive step, and conforms to the requirements for a new patent application, an application is filed here in accordance with the law.
