New description: [New technical field] This is a kind of adjustment structure for wheelchair armrests, especially for the front and rear telescopic adjustment and limit action on the branch unit. This creation is combined with a wheelchair as a handrail for better convenience. [Prior Art]
按，目前習用輪椅上之扶手結構，通常係直接固設於 輪％ ^侧，以提供使用者作為罪持或起身時施力之使 用；但是由於該扶手係固定設置於輪椅之二側，使其無法 符合一般使用者之體型及相關需求進行扶手之調整，造成 使用者莫大之不便及困擾。 此，如何創作出一種輪椅扶手之調整結構，以使使 者可將扶手之料進行前、後伸縮 而達到較佳之便利性，肢賴作所欲積極揭^之處動作，According to the current handrail structure of the wheelchair, it is usually fixed directly on the side of the wheel to provide the user with the use of force as a sin or when getting up; however, since the handrail is fixedly disposed on the two sides of the wheelchair, It is unable to meet the adjustment of the handrails of the general user's body type and related requirements, causing great inconvenience and trouble to the user. In this way, how to create a wheelchair armrest adjustment structure, so that the user can extend the armrest material forward and backward to achieve better convenience, and the action of the limbs is actively removed.

(4) Shrinking and limit action, and achieve more than this creation The main purpose of Is is to provide a wheelchair armrest q structure, 3 M409834 by the cooperation of the clamping portion and the pushing unit, so that the cushion can be moved forward and backward by the cushioning unit and the limit position, thereby achieving In combination with a wheelchair, it has the purpose of better convenience when used as an armrest. To achieve the above purpose, the adjustment structure of the wheelchair armrest of the present invention comprises: a support unit having a straight rod and a cross rod, the cross rod being at least one side active - There are a plurality of cassettes; a cushion that is combined with the activity of the support unit, one side of which is provided with a sliding slot that is movable across the crossbar, and one side of the cushion has a positioning hole that communicates with the chute , the positioning hole is due to The movement of the pad corresponds to the portion of the card at the appropriate position; and an pushing unit disposed in the positioning hole is adapted to abut the corresponding portion of the card. Thereby, the adjustment of the wheelchair armrest of the present invention The structure can be used in combination with a wheelchair as an armrest, so that the armrest cushion can perform the front and rear telescopic sliding and the limit position action, thereby achieving better convenience. [Embodiment] # To fully understand the purpose, characteristics and efficacy of the creation. The following is a detailed explanation of the creation by the following specific examples and with the accompanying drawings. The explanation is as follows: Please refer to "1st, 2nd and 3rd drawings", respectively An exploded view of a preferred embodiment, a partially enlarged schematic view of a portion of the first drawing of the present invention, and an external view of a preferred embodiment of the present invention. As shown in the figure, the adjustment structure of the wheelchair armrest includes at least one supporting unit. 1. A cushion 2 and a pushing unit 3. The above-mentioned supporting unit 1 comprises at least a straight rod 11, a crossbar 12 provided with 4 M409.834 at one end of the straight rod 11, and most activities are provided. Crossbar 12 The shank 13 has a plurality of accommodating holes 121, and the shank 11 is provided with a plurality of accommodating slots 121 for receiving the latching portion 13 at least on one side. Each of the latching portions 13 has at least one elastic member 131 disposed in the receiving groove 121, and a limiting end 132 having one end abutting against the elastic member 131 and extending from the other end to the receiving groove 121. The cushion 2 is The supporting unit 1 is movably coupled to one side of the sliding slot 21 which is disposed on the crossbar 12, and one side of the cushion 2 has a positioning hole 22 communicating with the sliding slot 21, and the positioning hole 22 is caused by The movement of the cushion 2 corresponds to the corresponding portion 13 of the cushion portion. The pushing unit 3 is movably disposed in the positioning hole 22 of the cushion 2 and can abut against the corresponding portion 13 of the appropriate portion, wherein the pushing The unit 3 includes at least one push rod 31 disposed in the positioning hole 22 and abutting against the limiting tip 132, a pressing portion 32 having one end abutting the push rod 31 and the other end extending from the side of the cushion 2, and a set of The push rod 31 has two ends that abut against the bottom of the positioning hole 22 and the elastic member 33 of the bottom surface of the pressing portion 32, respectively. Please refer to "4th, 5th, and 6th drawings", which are respectively a cushion card state diagram of a preferred embodiment of the present invention, and a cushion release state diagram of the preferred embodiment of the present invention and a preferred embodiment of the present invention. The cushion movement state diagram of the embodiment. As shown in the figure: When using (please refer to FIG. 1 at the same time), at least two supporting units 1 can be arranged on the two sides of the wheelchair by using the fixing holes 111 on the straight rod 11 and the fixing elements respectively (not shown) In the unadjusted state, the front end of the limiting end 132 of the latching portion 13 is locked by the elastic force of the elastic member 131 in the positioning hole 22 5 M409834 of the cushion 2, and thereafter The end is located in the receiving groove 121 of the cross bar 12, so that the cushion 2 is limited to the proper position of the cross bar 12. When the user needs to adjust the position of the cushion 2 due to getting up or performing other actions, the button can be directly pressed. The pressing portion 32 of the pushing unit 3 pushes the pressing portion 32 to push the push rod 31 and compress the elastic member 33 to push the push rod 31 to the front end of the limiting portion 132 to retract the push rod 31. The elastic member 131 is compressed in the groove 121 to move the limiting tip 132 away from the positioning hole 22 of the cushion 2. At this time, the user can move the cushion 2 forward and backward and release the pressing portion 32 to make the limiting portion. Abutting against the side wall surface of the chute 21, the cushion 2 is advanced on the crossbar 12 with its sliding groove 21, When the cushion 2 is moved to the predetermined position, the front end of the limiting end 132 of the other latching portion 13 disposed on the crossbar 12 is locked in the positioning hole 22 by the elastic force of the elastic member 131. The rear end of the limiting tip 132 is located in the receiving groove 121 of the cross bar 12, so that the cushion 2 can be adjusted to a proper position and then re-limited to the cross bar 12, thereby completing the adjustment and limitation of the cushion 2, so that the creation It is more convenient when used in combination with a wheelchair as an armrest. As mentioned above, this creation is fully in line with the three requirements of the patent: novelty, advancement and industrial availability. In terms of novelty and advancement, the creation is achieved by the cooperation of the cassette and the pushing unit, so that the cushion is supported on the support unit for the front and rear telescopic sliding and the limit position, thereby achieving the use of the wheelchair as a handrail. It has the advantage of better convenience; in terms of industrial availability, the products derived from this creation can fully meet the needs of the current market. The present invention has been disclosed in the above preferred embodiments, and it is to be understood that the present invention is only intended to depict the present invention and should not be construed as limiting the scope of the present invention. It should be noted that variations and permutations that are equivalent to the embodiment are intended to be within the scope of the present invention.
