Beach chair with simple locking means

A beach chair has a supporting means, a pivotal means fixed to the supporting means, a frame installed on the pivotal means and swayable with respect to the supporting means, a pair of armrest supports pivotally installed on the supporting means, and a cushion supported on the frame. The frame has a seat frame, a back frame fixed to the seat frame, and a leg frame pivotally fixed to the seat frame. An armrest support has a tube having a front end and a rear end, a pin support for pivotally installing the armrest support to the supporting means, a lock chamber, and an armrest installation surface; and a locking means having a handle, a pressing sleeve, and a pin.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a beach chair, and more especially, to a beach chair with a locking means which is simple.

2. Description of the Prior Art

Beach chairs an angle of a back thereof being adjustable have long been developed. When a user selects an angle he need, a position of the beach chair needs to be locked. A conventional locking means generally consists of a bolt which is able to be rotated to tightly press on a slidable tube to stop the tube moving with respect to a body of the beach chair. The position of the beach chair is thus locked. However, such locking means has some drawbacks. For example, in order to make the locking secure, the user has to rotate the bolt with his hand forcefully. It is painstaking and may hurt his hand. Sometimes it cannot be completed by a child. Furthermore, such means is liable to loose. And, this means is relatively complex in structure and thus will bring high cost in manufacturing.

BRIEF SUMMARY OF THE INVENTION

The main object of the invention is to provide a beach chair having a simple locking means.

In accordance with one aspect of the invention, there is provided a beach chair having a supporting means, a pivotal means fixed to the supporting means, a frame installed on the pivotal means and swayable with respect to the supporting means, a pair of armrest supports pivotally installed on the supporting means, and a cushion supported on the frame. The frame has a seat frame, a back frame fixed to the seat frame, and a leg frame pivotally fixed to the seat frame. An armrest support has a tube having a front end and a rear end, a pin support for pivotally installing the armrest support to the supporting means, a lock chamber, and an armrest installation surface; and a locking means having a handle, a pressing sleeve, and a pin.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

As shown inFIG. 1, a beach chair of the invention has a supporting means10, a pivotal means20fixed to the supporting means10, a frame30being installed on the pivotal means20and swayable with respect to the supporting means10, a pair of armrest supports40pivotally installed on the supporting means10, and a cushion50supported on the frame30. The frame30has a seat frame31, a back frame32fixed to the seat frame31, and a leg frame33pivotally fixed to the seat frame31.

With reference toFIG. 2, the armrest support40has a tube41having a front end411and a rear end (not shown), a pin support42for pivotally installing the armrest support40to the supporting means10, a lock chamber43, and an armrest installation surface44. A front linking pole45is pivotally installed on the leg frame33at one end thereof and inserted into the front end411of the tube41of the armrest support40at a free end thereof. The front linking pole45is able to slide in the tube41. A rear linking pole46is pivotally installed on the back frame32at one end thereof and inserted into the rear end of the tube41of the armrest support40at a free end thereof. A locking means50has a handle51, a pressing sleeve52, and a pin53. The pressing sleeve52has a curved inner surface521and an opposite flat outer surface522.

Further with reference toFIGS. 3 and 4, the handle51has a flange511, a hole512defined in the flange511, and a lever513. In installation, the pressing sleeve52is able to be inserted into the lock chamber43until the inner surface521meets the free end of the front linking pole45. And then the flange511of the handle51is able to be put into the lock chamber43. The pin53is finally inserted into an opening defined in the lock chamber43and goes through the hole512. The handle51is able to rotate around the pin53.

In use, a user is able to sit on the beach chair of the invention and move his body, making the frame30rotate around the pivotal means20, to select a preferred position of the frame30, and then push the lever513of the handle51to a closed position as shown inFIG. 5. In this position, a closed surface514will forcefully press on the outer surface522of the pressing sleeve52. The friction between the inner surface521of the pressing sleeve52and the free end of the front linking pole45will stop the front linking pole45sliding with respect to the armrest support40. The frame30is not able to sway around the pivotal means20any longer. When the user needs to adjust the position, he can push the lever513of the handle51in the direction A as shown inFIG. 5to an opened position as shown inFIG. 6. In this position, an opened surface515will not forcefully press on the outer surface522of the pressing sleeve52. The free end of the front linking pole45is thus able to slide with respect to the armrest support40. The user is able to select a new preferred position of the frame30and then close the handle51again.FIG. 7is a partial and schematic view showing the opened position of the handle with an armrest is installed, andFIG. 8is a partial and schematic view showing the closed position of the handle with the armrest is installed.

One who is skilled in the art will understand that the aforementioned embodiment of the invention as shown in the drawings and described above is for example only and not intended to be limiting.
