Description

M263938 Creation Instructions (1) [The scope of the first generation in the technical field includes all elderly walker skeletons provided with a retractor. The main one of which is a one-handed retractable structure including-which can be rotated to release the two sides. ',俾 Enables users to easily operate 3 brackets and fold them down and achieve labor-saving results. [Previous Technology] Due to the phenomenon of social structure change, it is too numerous to mention; the main function of the elderly is to provide And walking for a period of time, it is easy to get tired. When you walk, you can use the skeleton structure of the elderly walker to store it when the old person is tired. Agile, therefore, the inconvenience of folding into a skeleton when using it is based on the organization of the population. It is one of the items; Ji's people must borrow and relocate, and the special scooter will be tired. It is used to support the old structure; and for the skeleton of the scooter, the person sets a skeleton of the old man to lie in the image. When the walker can be received, the driving force uses a dual structure to make the age and the old move is more cautious than the walker, so that it must not be used to operate the current elderly product. The scooter is inconvenient, and at the same time, it can be folded with ordinary people when it is provided. [Content] Therefore, in order to solve the above-mentioned conventional elderly scooter skeleton, its skeleton is not easy to fold. One-handed folding structure for the elderly

Can be used to secure the user's toggle and the card of the frame positioning card; or use the take-up '俾 to make the skeleton to be pulled by the operator and use the principle of leverage, making the operation more suitable for action is more general His purpose and further insights. However, these explicit use 'because this creative amendment is clearly known in the industry and in the drawings, and should not be limited to this creative work. User. The following mentioned works can be taken from the drawings and only M263938. 4. Creation instructions (2) 'Mainly by the simultaneous release of both sides at the same time to release the main state of the retractor rod that releases the bullets on both sides of the skeleton.' It has The advantage and effort save the original creation. The detailed description of the Zhongqing embodiment is only for the purpose of describing various changes and these detailed descriptions for explanation. Instead, the car lever is moved to make the bamboo shoots move from the inside. Those who release both sides at the same time in the use of the elderly inconvenient to pull the car receiver can be used by the detailed description and the spirit and scope of the professionals, but these detailed descriptions are as follows: [ Implementation method] [Example 1] First, please refer to Figures 1 to 4. This creation is a one-handed folding structure for the elderly walker, which mainly provides the elderly with mobility problems when folding the skeleton of the elderly walker. It can be folded easily with one hand. This creation includes a folding frame 丨 〇, a one-hand folding structure 20, a drive frame 3, and an operation group 4. The folding frame 10 includes a front bracket 11, a rear bracket 12, a hand pushing frame 13, a folding group 14, a seat frame 15, front and rear wheel groups 16, 17 and a horizontal bracket 18.The front bracket 11 is connected to the rear bracket. 1 2 pivoted, and at the bottom of the front and rear brackets 11
