Definitions
- the present invention relates to a leisure folding chair connector, and more particularly to a cross bar connector.
- BACKGROUND OF THE INVENTION Most of the commonly used leisure folding chairs are connected by a cross-pivot connection to meet the functions of deployable support and convenient collection. As shown in Fig. 1, usually the two intersecting support rods are connected by a rivet. In use, the joint is a force receiving place. For a long time, the rivet is easily deformed or even broken, which affects the service life and use of the chair. Security.
- the utility model patent No. 00255139 discloses a "cross-connecting member of a leisure chair pole", which is a cylinder, and two cylinders are radially opened. "8" shaped through hole; two struts are inserted in two “8" shaped through holes and fixed to the cylinder by rivets; a gap between the two "8" shaped through holes is also formed Angle.
- the two rods of the leisure chair can be connected by the connecting member, and can be rotated and rotated in the "8"-shaped through hole to realize the crossing and closing of the strut, so that the contact area of the strut connection is increased, avoiding When the rivet is used for a long time, it will be deformed and broken, which will improve the service life of the chair.
- the connecting member of the structure on which the "8"-shaped through hole for the simultaneous movement of the two struts is required, the overall volume of the connecting member is relatively large, that is, the material is wasted and the appearance is not favorable; the other two Frequent rotation of the rod in the through hole 5 will cause the struts to easily wear out with the hole wall, such as stripping of the struts or thinning of the rod wall and deformation of the rod to affect the service life of the chair. .
- the utility model discloses a "connection structure of a bracket cross rod" disclosed in the utility model, wherein the base of the coupling member is a sleeve, and the outer wall of the sleeve extends outward to form a section and a sleeve body.
- a bracket having an angled upper end and an arcuate groove is formed.
- One of the two rods is sleeved in the sleeve, and the other rod is hooked into the bracket of the coupling.
- An object of the present invention is to provide a structure that is simple in structure, small in size, and supports a support rod while supporting High strength cross bar connector.
- the solution of the present invention is: a cross-bar connecting member integrally formed with two column holes for accommodating the struts, wherein the opposite side walls of one of the column holes are respectively from the upper end surface and the lower side
- the end surface is provided with a U-shaped groove communicating with the column hole; the two struts are respectively inserted into the two column holes, and are pivotally connected to the two column holes through the pivoting member.
- the connecting member is provided with a pivoting hole extending transversely through the two column holes at an intermediate position between the two column holes.
- the U-shaped groove has a depth greater than half the height of the column hole.
- the groove bottom of the U-shaped groove is a slope from the inside to the outside.
- the connecting member of the present invention is provided with only two column holes on one module, the connection of the two supporting rods is realized, and at the same time, the U-shaped groove of the two side walls of one of the column holes is arranged to make the two branches
- the rod can realize the function of cross-expansion and close-up.
- the structure is simple and small in size. Since the connector has two column holes arranged side by side on only one module, one of the column holes is always sleeved with one of the rods, and the other rod is slotted. The column hole rotates, so that the connecting member has a relatively small volume and a simple structure; in addition, the strut rotates in the U-shaped groove, and wear is not easily generated.

- Figure 2 is an exploded perspective view of the prior art 1;
- Figure 3 is a schematic view showing the implementation of the prior art 1;
- Figure 4 is an exploded perspective view of Prior Art 2;
- Figure 5 is a schematic view showing the implementation of the prior art 2;
- Figure 6 is a perspective view of the present invention.
- Figure 7 is a schematic view of the assembly 1 of the present invention.
- Figure 8 is a schematic view of the assembly of the present invention 2.
- Figure 9 is a diagram showing the state of implementation of the present invention.
- Figure 10 is a second embodiment of the present invention.
- the cross-bar connecting member of the present invention is integrally formed with a column hole 1, 2 of two accommodating struts 31, 32 which are juxtaposed on a module, and the two column holes 1, 2 Middle position Providing a pivot hole extending transversely through the two column holes 1, 2;
- the opposite side walls of one of the column holes 1 respectively have U-shaped grooves 11 and 12 communicating with the column hole 1 from the upper end surface and the lower end surface; the depth of the two U-shaped grooves 11 and 12 is greater than the height of the column hole 1 Half, the depth is the angle at which the struts 31, 32 are unfolded. The greater the depth, the larger the angle of deployment; the groove bottoms of the U-shaped grooves 11, 12 are inclined faces 111, 121 from the inside to the outside to match the struts 32. It fits more closely when the rendering is expanded.
- one of the two rods 31, 32 of the leisure chair 32 is always in the column hole 2, and the other rod 31 is at two U.
- the grooves 11 and 12 are rotated, and the struts 32 intersect (as shown in FIG. 9) and are close together (as shown in FIG. 10).
- the depth of the two U-shaped grooves 11, 12 determines the height of the seat when the leisure chair is deployed. . Since the strut 31 is supported by the bottom of the two U-shaped slots 11, 12 when the crossbar is deployed, the contact area of the connecting member with the crossbars 31, 32 is large, and the joint is stressed.
- the strength is also large, and there is no phenomenon that the pivoting member (rivet) 4 is deformed and broken after being used for a long time, thereby improving the service life of the chair; since the connecting member is provided with two column holes 1 in parallel on only one module 2, one of the column holes 2 is always sleeved with one of the struts 32, and the other struts 31 are rotated in the slotted column hole 1, so that the connector has a relatively small volume and a simple structure; The rod 31 rotates in the U-shaped grooves 11, 12 and is also less prone to wear.

Abstract
Élément de connexion de barres croisées pour une chaise pliable, comportant deux trous cylindriques paratactiques formés d'un seul tenant, destinés à recevoir les barres. Des rainures en forme de U sont prévues respectivement sur les parois latérales opposées inférieure et supérieure des trous cylindriques, et chaque rainure en forme de U peut passer au travers des trous cylindriques. Les rainures en forme de U sont ouvertes sur la surface supérieure ou sur la surface inférieure des trous cylindriques. Les deux barres sont logées respectivement dans les trous cylindriques, et fixées de façon pivotante aux barres par des éléments pivotants.
