Description

  The present invention relates to an armrest adjustment structure, and more particularly to an armrest adjustment structure suitable for use in a folding chair or a folding desk. In particular, according to the structure of the vertical movement of a kind of slip ring and universal bearing, the chair (desk) can be folded small and the volume can be reduced. It makes it more convenient to carry and store.

  At the same time, outdoor activities are universally emphasized, and many household items have the convenience of storage and carrying. According to the user's request, the current one has a folding function to make it easy to carry. Therefore, a structure that simplifies expansion and folding becomes important.

  The prior art will be described with reference to FIGS. The foldable chair (1) currently on sale is mainly composed of an armrest (11), front material (12), back material (13), back rod (14), outer cross rod ( 15). Among them, the armrest (11) is connected to a connecting object (111) that connects the front end (121) of the front member (12) and the front end (131) of the rear member (13), and the end of the armrest (11). (112) connects to the back rod (14). Further, the end (122) of the front member (12) is connected to the tip (151) 5 of the outer cross rod (15) with a reppet (123), and the end (132) of the rear member (13) is It connects with the connection thing (161) attached to a back leg rod (16). And the back rod (14) is a thing of bending, and it connects to the fixed thing attached to a rear leg rod (16), and the place near the center part of (162). The end (141) of the back rod (14) connects to a single ram (15) that attaches to the outer cross rod (152).

  Here, the problems of the prior art shown in FIGS. 1 to 3 are as follows.

  (Problem 1 of the prior art) Referring to FIG. 1, both back rods (14) have no fixed rods. In addition, since the end of the back rod (14) is connected to the ram (152), the gap (153) of the ram (152) is larger due to the tube diameter of the back rod (14). Therefore, the back rod is formed in a state where it easily shakes. If used for a long time, it is easy to break or happen and is very dangerous.

  (Problem 2 of the prior art) Since the lippet (152) is obstructed by the intersection (154) of the outer cross rod (15), it cannot move.

The prior art that the applicant of the present application knows at the time of filing a utility model registration is as described above and is not a device known in the literature, so there is no prior art information to be described.

  The present invention has been made in view of the above-described various problems of the prior art, and an object thereof is to provide an armrest adjustment structure having convenience and practicality. It is.

  In other words, the inventor considered improvement, combined practical experience with constant research and improvement, and finally devised an armrest adjustment structure suitable for use as a kind of folding chair or folding desk. The following design objects can be achieved by the design of the present invention.

  The purpose of the design of the present invention is to provide an adjustment structure for an armrest of a kind of folding chair (desk). As shown in FIGS. 7 to 9, the present invention is applied to an adjustment structure in an armrest of a folding chair. Mainly combined with armrest (2), lippet (21), claw-type flange joint, downward convex object (212) and universal bearing (22). Among them, one end of one armrest (2) is repetted to the joint (214) extending from the slip ring (21), and one end is provided with a universal bearing and connected to the rod. There is one hole for connecting to the rod in the center of one slip ring (21). The joint extending from one end of the slip ring (21) is designed to attach a slip to one end of the armrest and can be moved up and down on the rod. One claw flange joint (211) is slipped on one side of the slip ring. There is a downward convex at the end. One downward projection (212) is located at the end of the claw flange joint. One universal bearing (22) is located at one end of the armrest and is connected to the rod. There is a structure that can be folded or folded on the armrest. The movement of the rotation proceeds with the movement, which is advantageous for the folding or folding of the folding chair.

  In order to achieve the above object, the armrest adjustment structure according to the present invention is mainly composed of one armrest and one slip ring, and one end of the armrest is an axial center, and one end is provided with a slip ring, and its free Centering on the shaft hook, the slip ring can be moved up and down on the rod, there is a hole in the center of the slip ring to connect to the rod, one end has a joint extending from it, one end of the armrest Although it is for slipping, the other end is installed with one claw-type flange joint and one lower convex object, and the flange attached to the tip of the rod is fitted or separated, so that It is intended to be expanded and stored inward.

That is, the present invention relates to an armrest adjustment structure in a folding chair (desk), and includes an armrest, a slip ring, a universal bearing and a rod. When the armrest moves during unfolding and folding, the slip ring and the universal bearing can be pulled. I will explain more. First, the universal bearing is moved upward along the foot axis to an appropriate position, and a claw-type flange joint attached to the slip ring is fitted into a flange attached to the tip of the foot shaft. Then you can deploy. Conversely, the flange joint under the slip ring is pushed to separate the claw-type flange joint of the slip ring into the flange, and the universal bearing is moved downward along the foot axis. Then you can fold it. The design of this idea makes it more convenient for storing and transporting chairs and desks. Overall, it has extremely good convenience and practicality.

  The present invention has an excellent effect that an armrest adjustment structure having convenience and practicality can be provided.

  In order to clearly describe the features and characteristics of the structure of the present invention, it will be described in detail below with reference to the accompanying drawings.

  Reference is first made to FIGS. 7 and 8 of the present invention. When the user intends to unfold the folding chair, first, the armrest (2) is pulled up, and at the same time, the slip ring (21) is moved up and down on the rod (23). And it stops on the connection thing (231) of the front-end | tip of a rod (23). Then, the downward convex object (212) extending from the end of the claw-shaped flange joint (211) is pushed, and the claw-shaped flange joint (211) and the flange (231) of the connected object (231) are fitted. Then, the deployment of the folding chair can be completed easily.

  On the other hand, the case of folding will be described with reference to FIGS. 11 and 12 of the present invention. First, the downward convex object (212) extending from the end of the claw-shaped flange joint (211) is pressed to separate the claw-shaped flange joint (211) into the flange (231) of the connected object (232), and the slip ring Move down (21). Then you can store the folding chair. Then, when the slip ring (21) is moved to the end of the rod (23), it is folded. Since the volume is reduced, it is convenient to carry and store.

  Reference is also made to FIG. 15 of the present invention. This is a three-dimensional view when applied to the folding desk (3). There is a joint (311) extending from both ends of the slip ring (31), which attaches a slip to one end of the armrest (331). The slip ring (31) is located on the main frame (32) installed in the center of the folding desk (3) (see FIG. 16), but the universal bearing (33) is one end of the armrest (331). The rod (34). It is advantageous for the slip ring (31) of the main frame (32) to move downward when folding, and the folding desk (3) can be easily stored and unfolded.

Reference is now made to FIG. 19 of the present invention. This is also an implementation illustration when applied to the folding desk (4). Among them, the slip ring (42) is also connected to the rod (43). There is a stretched joint (421) at one end of the slip ring, and a slip is attached to one end of the armrest (411). The universal bearing (421) is located at the tip (44) of the main beam. The slip ring (42) is moved downward during storage, and the volume of the folding desk (4) after storage can be reduced due to the characteristics of the universal bearing (41) (see FIG. 20). ). Further, the slip ring (42) can be moved upward, and the folding desk (4) can be unfolded and fixed.
