Clamping Handle Device, Carrying Bag, and Electronic Device Stand Using the Same

This application claims the benefit of U.S. provisional patent application No. 63/637,450, filed on Apr. 23, 2024, which is incorporated herein by reference in its entirety.

The present disclosure relates generally to a clamping handle device, a carrying bag, and an electronic device stand using the clamping handle device. The clamping handle device provided in this disclosure can be switched to different configurations for clamping an item, loosening the item and carrying the item. It can also be adjusted to be used as an electronic device stand. The carrying bag provided in this disclosure can directly contain food, without the need for additional bags, which is environmentally friendly. Moreover, the carrying bag is easy to fold and store, and it is stable when in use, reducing the risk of tipping over.

Items without handles, such as documents, books or food bags, can only be held by gripping them with the palm or cradling them in the arms to prevent them from slipping out of the hands or arms, due to the absence of handles. Holding items in these manners for extended periods can easily lead to fatigue and makes it difficult to lift or lower the items.

Nowadays, environmental protection has become an issue of attention in various countries. Disposable plastic boxes or cartons used for containing food generate a large amount of garbage or non-degradable materials. The recycled food boxes can replace disposable plastic boxes, however most recycled food boxes capable of carrying solid food or liquid food in the market are made of hard plastic and glass materials, which occupy space and are inconvenient to carry. In addition, whether disposable boxes or recyclable boxes are used, extra plastic bags or heat preservation bags are often required to carry the boxes, exacerbating environmental pollution. On the premise of being environmentally friendly, the quantity of non-degradable garbage can be reduced by reducing the use of disposable boxes and plastic bags, thereby lessening the environmental burden.

Existing silicone or fabric food bags are prone to deformation and struggle to remain upright. When used to hold liquids, they are also prone to leaking. Such food bags require multiple folds to seal the opening, which is time-consuming and often results in an ineffective seal.

In one aspect, the disclosed embodiments provide a clamping handle device for holding items.

The following clearly and completely describes the technical disclosures in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of this application.

It is understood that although the terms “first,” “second,” and the like may be used herein to describe different elements, these elements should not be limited by these terms. These terms are merely used to distinguish one element from another. Thus, a first element may be referred to as a second element without departing from the teachings of the disclosed concept.

Unless otherwise explicitly specified and defined, the terms “coupled” in this application should be understood broadly, for example, may be a fixed connection, or may be coupled through an intermediary medium, or may be internal communication between two elements or an interaction relationship between two elements. For those of ordinary skill in the art, the specific meaning of the above terms in the present disclosure may be understood according to specific conditions.

As shown in, a clamping handle device is provided with a clamping bodywith a handle componentattached thereto.

As shown in theand, the clamping bodyincludes a first clamping portionand a second clamping portionhingedly coupled to the first clamping portion. An end of the first clamping portionmay be hingedly coupled to an end of the second clamping portionby a pivot shaft. A cavity is formed between midsections of the first clamping portionand the second clamping portionand configured to accommodate at least a part of the clamped item. The first clamping portionand the second clamping portionboth include distal ends positioned away from the pivot shaftthat collectively define a clamping mouth. The clamping mouth is configured to be selectively opened and closed.

A torsion springis sleeved over the pivot shaft, with two ends of the torsion springrespectively abutting against the first clamping portionand the second clamping portion. The torsion springis configured to bias the first clamping portionand the second clamping portiontowards a closed position of the clamping mouth.

The handle componentincludes a first handleand a second handle. The first handleis disposed on the first clamping portion, and the second handleis disposed on the second clamping portion. The first handleand the second handleeach at least partially slidable relative to the clamping bodyand positioned on opposite sides of the clamping mouth.

The first clamping portionand the second clamping portionare slidably coupled to the first handleand the second handlerespectively. For example, the first clamping portionincludes through-holes, and the first handleat least partially disposed through the through-holes and reciprocate within the through-holes. The connection relationship between the second clamping portionand second handleis similarly configured. The second clamping portionincludes through-holes, and the second handleat least partially disposed through in the through-holes and reciprocate within the through-holes.

The first handleincludes a first handheld portionand a second handheld portionhingedly coupled to the first handheld portion. And the second handlealso includes a first handheld portionand a second handheld portionhingedly coupled to the first handheld portion. Relative to each other, the first handheld portionis closer to the pivot shaft, and the second handheld portionis closer to the clamping mouth.

The first handheld portionand the second handheld portionare hingedly coupled about a hinge joint, the hinge joint is positioned between the first handheld portionand the second handheld portionin the same handle. When it is necessary to open the clamping mouth, the hinge joint of the first handleis slid out the clamping bodyon a side adjacent to the clamping mouth. And the hinge joint of the second handlealso slid out the clamping bodyon a side adjacent to the clamping mouth. This configuration may avoid the clamping bodyinterfering with rotation of the second handheld portionto open the clamping mouth.

In one embodiment, in the same handle, for example in the first handle, the hinge joint of the first handheld portionand the second handheld portionis movable to an interior of the clamping body, an exterior of the clamping bodyon a side adjacent to the pivot shaft, and an exterior of the clamping bodyon a side adjacent to the clamping mouth.

When the hinge joint is located out of the clamping bodyon the side adjacent to the clamping mouth, the first handheld portionextends out of the clamping bodyon the side adjacent to the pivot shaft. This configuration ensures that a portion of the first handheld portionis always positioned outside the clamping body. When hand-carrying is required, a user may pull the extended portion of the first handheld portion, thereby facilitating operation. The distal end of the second handheld portion, which is away from the hinge joint, is capable of rotating in a direction away from the clamping mouth, thereby opening the clamping mouth.

When the second handheld portionis rotated in a direction away from the clamping mouth and contacts the clamping body, a distal end of the first handheld portion, located away from the hinge joint, is positioned lower than the distal end of the second handheld portion, located away from the hinge joint. This configuration may avoid the interference of the first handheld portionin the rotation of the second handheld portionduring opening the clamping mouth and facilitate the clamping force applied by the user.

When the hinge joint is located out of the clamping bodyon the side adjacent to the pivot shaft, the second handheld portionextends out of the clamping bodyon the side adjacent to the clamping mouth. This configuration ensures that a portion of the second handheld portionis always positioned outside the clamping body. When it is necessary to open the clamping mouth, a user may pull the extended portion of the second handheld portionto cause the hinge joint to slide out of the clamping bodyon the side adjacent to the clamping mouth, and then rotate the second handheld portion.

By adjusting the hinge joint and a rotation angle of the second handheld portion, the componentis provided with multiple configurations to achieve different functions.

As shown in, when it is necessary to open the clamping mouth, the handle componentis transformed into a first configuration, in which the hinge joints of the handle componentare located out of the clamping bodyon the side adjacent to the clamping mouth. Both second handheld portionsare rotated in the direction away from the clamping mouth, forming a structure similar to a dovetail clamp with the clamping body. Continued rotation of the two second handheld portionstowards the pivot shaftseparates the ends of the first clamping portionand the second clamping portionadjacent to the clamping mouth, thereby opening the clamping mouth to receive an item for subsequent clamping.

When it is necessary to carry the item by hand, the handle componentis transformed into a second configuration, in which the external force is removed, and the ends of the first clamping portionand the second clamping portionadjacent to the clamping mouth move towards the closed position of the clamping mouth under the action of the torsion spring, thereby firmly holding the item. Users may hold the first handheld portionto carry the item. In the second configuration, the main body of the first handheld portionand the second handheld portionof the same handle are configured to the handle's extension directions or be substantially aligned.

As shown in the, when the extension directions of the main body of the first handheld portionand the second handheld portionof the same handle are substantially aligned, each of the hinge joints of the handle componentis positioned outside the clamping bodydistal from the clamping mouth, thereby providing the user with a larger hand-holding space.

In one embodiment, the hinge joint of the first handheld portionand the second handheld portionis slidable to an interior of the clamping bodyand an exterior of the clamping bodyon a side adjacent to the clamping mouth.

In the first configuration, the hinge joints of the handle componentare located out of the clamping bodyon the side adjacent to the clamping mouth. Both second handheld portionsare rotated in the direction away from the clamping mouth, forming a structure similar to a dovetail clamp with the clamping body.

In the second configuration, the ends of the first clamping portionand the second clamping portionadjacent to the clamping mouth move towards the closed position of the clamping mouth under the action of the torsion spring. The main body of the first handheld portionand the second handheld portionof the same handle are configured to the handle's extension directions or be substantially aligned. When the extension directions of the main body of the first handheld portionand the second handheld portionof the same handle are substantially aligned, each of the hinge joints of the handle componentis positioned in the interior of the clamping body, thereby providing the user with a larger hand-holding space.

In one embodiment, in a direction extending from the clamping mouth towards the pivot shaft, a distance between the first clamping portionand the second clamping portionfirst increases and then subsequently decreases. A longitudinal cross-section of the first clamping portionmay be approximately C-shaped. Specifically, the first clamping portionincludes, in sequence from a distal side to a proximal side relative to the clamping mouth, an upper wall, a transition walland a lower wall. The upper walland the lower wallare each configured as an inclined plate. Each of the upper walland the lower wallincludes a through-hole, and the first handleis slidably disposed through the through-holes of the upper walland the lower wall. This design is configured to operatively constrain the movement direction of each the first handleand the second handlesuch that it aligns with the line connecting the centers of the two through-holes.

An additional sectionis provided on a side of the lower walladjacent to the clamping mouth. In a state without external force, the clamping mouth is closed, and the two additional sectionsare in contact with each other, thereby increasing a clamping contact area and ensuring a clamping effect.

In one embodiment, the first clamping portionis identical in structure to the second clamping portion, the first clamping portionand the second clamping portionare mirror-symmetrical.

In one embodiment, as shown in, in the same handle, the first handheld portionincludes two first rods and a first connection section disposed between and connected to the two first rods. The second handle portionincludes two second rods and a second connection section disposed between and connected to the two second rods. The first rod is pivotally coupled to the second rod in a one-to-one correspondence, and each cooperative set of the first rod and the second rod is slidably coupled to the clamping bodythrough at least one hole.

The first handheld portionand the second handheld portionare both U-shaped, and together form a rectangular loop, which prevents the handle componentfrom sliding out of the clamping body. The first connection sections also facilitate holding.

To enhance usability, both the first handheld portionand the second handheld portionare equipped with anti-slip sleeves on their connection sections. These anti-slip sleeves are made of rubber.

In one embodiment, the hinge joint includes: an end platedisposed on a proximal end of the first handheld portionnear the second handheld portion, a connecting shaft protruding from the end plate, and a connecting headdisposed on a proximal end of the second handheld portionnear the first handheld portion. The connecting headis rotatably mounted on the connecting shaft. Optionally, two end platesare symmetrically disposed, and the connecting shaft is disposed between the two end plates.

In one embodiment, the second handleis identical in structure to the first handle.

In one embodiment, the clamping handle device is made of a hard material.
