Description

Technical Field

[0001] The invention relates to the technical field of sandboxes, in particular to a portable sandbox. Background Art

[0002] Sandplay therapy is a popular psychotherapy method internationally. It's widely used in schools and kindergartens for children's psychological education and psychotherapy, and is also very popular in universities and adult counseling clinics. By awakening the childlike innocence, people find a way back to their hearts, thereby resolving issues such as psychosomatic disorders, social maladjustment, and personality developmental disorders through the sandplay. Sandplay therapy is a psychotherapy method based on the principles of Jungian psychology and developed by Dora Kalff. Sandplay is a creative form of therapy that uses imagery (active imagination) and is a "focused distillation of physical and mental life energy." Its characteristic feature is the creation of a "free and protected space" where clients can freely follow their inner thoughts, using sand, water, and sand tools to create images and express their deepest inner needs. The series of images expressed in the sandplay foster an ongoing dialogue between the conscious and unconscious within the player's mind, stimulating a healing process and the development of spirituality and individuation. Sandplay is often used in family counseling. By observing parents and children co-create a family sandplay, counselors can help parents understand the limitations of current parent-child interaction models. By encouraging both parents and children to express their own sandplay stories, counselors can relax and express their inner thoughts non-verbally, thereby promoting communication and resolving conflicts. The process of placing, moving, and adjusting sandplay tools can subtly alleviate players' psychological issues and alleviate symptoms of mental illnesses such as anxiety, phobias, social anxiety, depression, behavioral deviations, and personality disorders.

[0003] The sandboxes used in general psychological counseling rooms are large in size and require a large shelf to place the complete set of sand tools. In order to facilitate carrying, a Chinese patent has disclosed a portable sandbox with the patent number: CN113509737A. It includes a sandbox and a placement rack. A storage cabinet is provided under the sandbox, and rollers are provided at the bottom of the storage cabinet. The storage cabinet includes a placement area and a drying area. The placement rack has a folding function, and the folded placement rack can be placed in the placement area. The drying area is provided with a heater, a ring conveyor chain, a collection box, and a trigger rod. The bottom of the sandbox is provided with a sand drop hole connected to the drying area. A connecting plate is fixed on the ring conveyor chain, and a material receiving tray is rotatably connected to the connecting plate. The trigger rod is fixed in the drying area and is located above the collection box. The trigger rod can rotate the material receiving tray to dump sand into the collection box. This solution provides a sandbox, a storage cabinet with a drying function, and a placement rack with a folding function, so that all the items needed for sandbox games can be carried and moved together with the storage cabinet, making it convenient for psychotherapists to perform sandbox games in different places. A Chinese patent discloses a portable sandbox with the patent number CN219105639U, which includes a sandbox body. The inner wall of the sandbox body is provided with a fixing mechanism. The fixing mechanism includes a spring, a cross plate, a connecting rod, a slider, and a slide bar. The top of the spring is fixedly connected to the inner wall of the sandbox body, one end of the spring is fixedly connected to the top of the cross plate, the front end face of the cross plate is rotatably connected to one end of the connecting rod, and one end of the connecting rod is rotatably connected to the front end face of the slider. By pushing the slide bar to move, the slide bar drives the cross plate to move and compresses the spring at the same time, the cross plate drives the connecting rod to move, and the connecting rod drives the slider to move. When the slider retracts inward, it no longer engages the support legs, and the support legs can be disassembled. After the sandbox is used, the four support legs are easily folded up. The support legs do not take up much space during transportation, thereby facilitating the transportation of the sandbox. The sandbox is easy to carry, which improves the transportation efficiency of the sandbox. A Chinese patent application, patent number CN207898754U, discloses a portable sandbox. The box comprises a top-opening upper box and a front-opening lower box. Vertical fixing rods are fixed to the four corners of the upper box. The top of the fixing rods has a socket, and one side of the fixing rods has several through-holes, each of which is equipped with bolts. Above the fixing rods are vertical support rods, the lower ends of which can be inserted into the sockets of the fixing rods. Above the fixing rods is a sandbox with an open top, the bottom of which is fixedly connected to the upper ends of the support rods. The present invention allows sand to be placed in the sandbox and sand tools to be placed in a storage box, making it portable. When multiple users use the present invention, placing sand together can help improve their social skills. Children also benefit from playing in the sandbox by playing. After the storage box is pulled out, it can be rotated by a second slider, allowing multiple storage boxes to effectively utilize space.

[0004] Although these three patents are easy to carry, the operation is relatively cumbersome and not suitable for daily home use. As a result, the sand inside the user's sandbox is prone to leakage, making it inconvenient for the user to carry, thus affecting the user's normal use. Summary of the Invention
