The invention relates to key clasps and handbag hanging devices; more particularly, it relates to a multi-function bag hanging device and key clasp.
Because the volume of a key is rather small, a key clasp is used to link multiple keys together. However, a conventional key clasp still has the problem of not being easy to carry, and many people like to put their key clasp in a bag when they go out. But then it is not easy to find in the bag when they want to use it.
One particular key clasp addressing these problems has three parts: an elongated body section, a purse clamping section, and a hook section. The body section is generally an elongated metal strip with a bent closed loop at one end (hook section) in which to hang the key ring, and a bend of about 180 degrees at the other bent end (clamping section) for clamping onto a bag or bag lining cloth, with the shorter end of the 180 degree bend on the outside of the bag, making it easy to find the key clasp when it is wanted. See for example U.S. Pat. Nos. 7,308,922 and 7,537,032 the disclosures of which are herewith incorporated by this reference as if fully set forth herein.
Such key clasps however have only a relatively small clamping force between the metal strip of the clamping section and the metal strip of the body section, so it is easy for it to come loose when clamped on a bag, especially a relatively thin bag. In addition, current key clasps have only the one function of hanging keys and cannot be used as bag hanging devices. What is needed is a multi-function bag hanging device convenient for carrying so it can be used not only as a bag hanging device, but can also be placed inside a bag to act as a key clasp.
What is disclosed is a multi-function bag hanging device that can be used not only as a bag hanging device, but also as a key clasp.
Also disclosed is a shaft or hinge device for a bag hanging device that includes a shaft sleeve, shaft, cam, pressure wheel, and helical compression spring. One end of the shaft sleeve is the closed end with a through hole at its center, and the other end of the sleeve is an open end, and the cam seats at the open end of the shaft sleeve and can rotate with respect to the shaft sleeve. The inside end of the cam seats inside the shaft sleeve, and the outside end of the cam projects out of the shaft sleeve along the axis thereof, and there is a catching groove at the center of the end surface of the outside end of the cam; there is a catching disc provided on one end of the shaft, and there is a concave groove perpendicular to the axial direction of the shaft at the other end thereof; the shaft successively passes through the cam and the pressure wheel and helical compression spring seating inside the shaft sleeve; the catching disc fits inside the catching groove of the cam, and the other end of the shaft passes through the through hole to the outside of the closed end of the shaft sleeve; there is a catching button provided in the catching groove to restrict the axial movement of the shaft; the pressure wheel is sleeved on the inner wall of the shaft sleeve and rotates synchronously with the shaft sleeve; it can also move axially along the shaft sleeve, and a concave-convex shape in the axial direction along the shaft is formed at the inside end of the cam, a concave-convex shape is also correspondingly formed at the surface of the pressure wheel facing the cam; the helical compression spring rests between the pressure wheel and the closed end of the sleeve.
The disclosed bag hanging device has a body section and a clamping section, with one end of the body section rotatably connected with the clamping section by a hinge or shaft device. In one embodiment, the outer housing of the shaft sleeve is inserted into the body section and a first stopping piece is provided at the end of the body section connecting with the clamping section to limit the rotation angle of the clamping section. The outside end of the cam is inserted into the clamping section, and the free end of the clamping section rests on the body section.
The bag hanging device also includes a hook section and the other end of the body section is rotatably connected to the hook section through a hinge or shaft device. In one embodiment the outside housing of the shaft sleeve is inserted into the hook section and a second stopping piece for limiting the rotation angle of the hook section is provided at one end of the hook section connecting to the body section. The outside end of the cam is inserted into the body section, and the free end of the hook section rests on the body section.
Preferably the hook section and the clamping section are respectively located at opposite ends of the body section. Preferably the body section end connecting with the hook section is bent to the side of the body section end that connects with the clamping section. In other words, the body section end connecting with the hook section is offset from the body section end that connects with the clamping section. This offset may be an angular offset, or a curved offset, but in either case, a longitudinal line passing generally through the body section end that connects with the clamping section does not also pass through the angled or curved body section end connecting with the hook section.
Preferably there is a clamping disc at the free end of the clamping section. The clamping disc can be round, rectangular, oval, or heart shaped among other possible shapes. The clamping disc is optionally provided with a backing of rubber-like grip material and an LED light.
The shaft device used for the bag hanging device in this disclosure rotatably connects the clamping section or hook section to the body section and maintains a clamping force against the body section. In addition, the clamping section and hook section each have physical stops or limits to their angular rotation out from the body section, so that a particular angular rotation can be maintained in a stable condition after rotating to a certain angle relative to the body section. The hook section can be used to hang a bag or other object when the clamping section is placed on top of a table. When the clamping section and the hook section of the bag hanging device are closed against the body section (clamped together) under the tension of the included spring, the device can then be used as a key clasp.
In some representative embodiments there is a shaft device for a bag hanging device. The shaft device has a shaft sleeve, a shaft, a cam, a pressure wheel, and a helical compression spring. One end of the shaft sleeve is a closed end with a through hole at its center. The other end of the shaft sleeve is an open end, and the cam is situated at the open end of the shaft sleeve and is rotatable relative to the shaft sleeve. An inside end of the cam is situated inside the shaft sleeve, and an outside end of the cam projects out of the shaft sleeve along the axial direction of the shaft sleeve. A catching groove is provided on the center of an end surface of the outside end of the cam.
A catching disc is provided on one end of the shaft, and a concave groove perpendicular to the axial direction of the shaft is provided at the other end of the shaft. The shaft successively passes through the cam and the pressure wheel, and the helical compression spring is inside the shaft sleeve. The catching disc is held inside the catching groove of the cam, and the other end of the shaft extends through the through hole to the outside of the closed end of the shaft sleeve. A catching button is provided in the concave groove to limit the movement of the shaft along its axial direction.
The pressure wheel is nested in the inner wall of the shaft sleeve rotating synchronously with the shaft sleeve and movable axially along the shaft sleeve. A concave-convex shape in the axial direction along the shaft is formed at the inside end of the cam, while a concave-convex shape is correspondingly formed on a surface of the pressure wheel facing the cam. The helical compression spring rests between the pressure wheel and the closed end of the sleeve.
In other representative embodiments, there a bag hanging device with a body section and a clamping section. Desirably, one end of the body section rotatably connects with the clamping section by a shaft device, such as that described just above, and an outer housing of the shaft sleeve is connected to the body section in an insertion manner. A first stopping piece provided at one end of the body section connects to the clamping section to limit the rotation angle of the clamping section. The outside end of the cam connects to the clamping section in an insertion manner, and the free end of the clamping section rests on the body section.
The bag hanging device desirably has a hook section, and the other end of the body section is rotatably connected to the hook section through a shaft device wherein an outer housing of the shaft sleeve is connected to the hook section in an insertion manner, as above with the clamping section, and a second stopping piece is provided at the end of the hook section which connects to the body section to limit the rotation angle of the hook section. The outside end of the cam is connected with the body section in an insertion manner, and the free end of the hook section rests on the body section.
A multifunctional bag-hanger is also disclosed. It has a body portion, a hook portion connected to one end of the body portion for hanging articles, and a clipping portion rotatably connected to the other end of the body portion by a first rotating shaft. A clipping disk is on a free end of the clipping portion. The clipping disk is held releasably closed on the body portion with interengageable magnets provided at corresponding positions on the clipping disk and the body portion respectively.
For instance, a first magnet is provided on a side of the free end of the clipping disk opposite to the body portion when in a closed position, and a second magnet is provided at the corresponding position on the side of the body portion being opposite to the clipping disk magnet. Generally, the hook portion and the clipping portion are positioned on two sides of the body portion, respectively. The hook portion and the body portion are rotatably connected by a second shaft, such that at least a portion of the hook portion is elastically biased against the body portion. The elastic is advantageously a helical spring which is sleeved on the second rotating shaft and whose two protruding catching ends are stuck onto the hook portion and the body portion respectively. To these ends, a slot is provided at one end of the body portion that is connected to the hook portion, and a support chip or guide is provided on the slot. A blind hole is opened at the end of the hook portion that is connected to the body portion in the direction of its length, and the support guide extends into the blind hole. The spring component is positioned inside the blind hole and sleeved onto the support guide. A rubber-like layer is coated on the inner side of the clipping disk.
In another embodiment, a device is selectably movable between a “clasp” configuration and a “hanger” configuration. In the device there is a device body, a first spring biased hinge at a first end of the device body and a second spring biased hinge at a second end of the device body, a clip hingedly connected to the first end of the body, and a hook hingedly connected to the second end of the body.
The hinges bias the device to a closed position clasp configuration and the clip and the hook are swingable against spring bias to an open position hanger configuration. The device desirably has physical stops to limit angular motion of both clip and hook to less than 90 degrees each.
In some disclosed devices, the device body has a first body segment distally bounded by the first end of the body, and a second body segment distally bounded by the second end of the body. Each body segment is bounded proximally by each other. The second body segment and the first body segment are angularly offset from one another.
The device has a first body segment center line formed by the intersection of sagittal and frontal planes of the first body segment generally bisecting the first body segment respectively into right and left halves and front and back halves, and a second body segment center line formed by the intersection of sagittal and frontal planes of the second body segment generally bisecting the second body segment respectively into right and left halves and front and back halves. The first and second body segments are angularly offset from one another by an angle that is the angle between the two body segment centerlines.
The angular offset of the first body segment from the second body segment is preferably an angle from 135 degrees to 180 degrees, where 180 degrees is flat, meaning not offset from each other. More preferably the angle is from 157 degrees to 177 degrees, though other degrees of angular offset can be made to serve. For instance, the angular offset of the first body segment from the second body segment can be any angle from 135 degrees to 179 degrees, such as angles selected from angle ranges from 135 degrees to 144 degrees. from 145 degrees to 154 degrees, from 155 degrees to 164 degrees, or from 165 degrees to 180 degrees.
The device second segment is advantageously fully or partially curved and its frontal plane is understood to be the plane that contains both ends of the second segment.
In the open position hanger configuration, the clip and the hook are generally not parallel to each other and are offset from each other at an angle of less than 90 degrees, and preferably around 60 degrees.
The device alternatively has a first magnet on a side of a free end of the clip distal from the device body portion, and a second magnet at a position on a front side of the device body opposed by the clip and first magnet. The second magnet and the first magnet are oppositely poled to attract each other. The device has at a distal end of the clip a plate for engaging a flat surface such as a table top, with a layer of rubber-like material on a table engaging side of the plate.
The device alternatively has at a distal end of the clip a thin profile clasping case (like a compact or locket), inside of which is disposed at least one mirror and or a photo frame with a magnetized photo cover for easy positioning and replacement of a photo in the frame. Advantageously, the photo frame has a removable iron ring, under which there is at least one magnet for biasing the frame closed upon the case.
An alternate device is selectably movable between a “clasp” configuration and a “hanger” configuration, and has a device body, a first hinge at a first end of the device body and a second hinge at a second end of the device body, a clip hingedly connected to the first end of the body, and a hook hinge dly connected to the second end of the body. The clip and the hook are swingable to an open position hanger configuration, and the device has physical stops to limit angular motion of both clip and hook to less than 90 degrees each.

The connection between the body section 11 and the clamping section 12 and hook section 13 for the bag hanging device in this implementation example uses the shaft device 3 described above. Because of the effect of the cam with the pressure wheel and helical compression spring in the shaft device 3, when being used as a key clasp, the clamping section 12 and hook section 13 both rest on the body section 11 and can maintain a certain clamping force. A certain clamping force needs to be exerted in order to be able to rotate them. When being used as a bag hanging device, the clamping section 12 and the bending section 13 can both maintain stability after rotating to a certain angle relative to the body section 11, and they can bear a certain external force.
