Other embodiments will become apparent to those of ordinary skill in the art by reading the following detailed description, with reference where appropriate to the accompanying drawings.
Example embodiments are described herein with reference to the drawings.
The drawings are schematic and not necessarily to scale. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise.
This description describes several example embodiments, at least some of which pertain to pliers, such as hose clamp pliers that are configured for removing or installing hose clamps. Hose clamps are used to secure and seal hoses onto connections or fittings. Typically, the hose is placed over the connection and the hose clamp, which has a ring-shaped configuration, is positioned to surround the hose and secure the hose to the connection. The hose clamp provides pressure on the hose to hold the hose in place and to form a seal between the hose and the connection. While traditional clamps may loosen over time or with changes in temperature, some hose clamps are designed to maintain tension on the hose irrespective of changes in other factors, such as changes in temperature. Such hose clamps may be referred to as constant tension hose clamps.
Spring tension hose clamps are a type of constant tension hose clamp that are employed for various applications, such as automotive systems, including cooling systems. A spring tension hose clamp may be formed of a metal band or wire, for example, which is formed in a ring with ends that pass one another. Tabs are often included on the ends and configured to allow the hose clamp to be opened. For example, by pressing the tabs together, the diameter of the ring expands, thereby allowing the clamp to be placed over a hose. Once the tabs are released, the elastic properties of the material will cause the clamp to contract to a smaller diameter, thereby placing a clamping force on the hose, in the manner of a spring. In other words, the spring force within the hose clamp maintains the smaller diameter of the hose clamp, while the application of an exterior force allows the hose clamp to expand.
Various tools can be used for expanding a hose clamp. Hose clamps pliers are particularly useful in many scenarios where hose clamps need to be removed or installed. The operation of hose clamp pliers is typically familiar to users, as the general operation is similar to all pliers, where the jaws of the pliers are opened and shut by rotating opposing halves of the pliers using their respective handles. Accordingly, hose clamp pliers typically do not require significant training or practice to use. Further, in some embodiments, the hose clamp pliers may also be versatile in their use and capable of gripping a broad range of objects other than hose clamps. This versatility also makes hose clamp pliers an attractive option to have available. Further, hose clamp pliers can be held and positioned to fit into a wide range of spaces where hose clamps may be employed. The pliers may also be configured to engage the hose clamp from various angles, further increasing the versatility of this tool. Embodiments of the hose clamp pliers described herein, in particular, can be used to engage and expand a variety of types of hose clamps from various different angles or positions while maintaining engagement with the hose clamp.
While the hose clamp pliers 100 may be configured so that they can be opened to a wide gap between the first jaw portion 120 and second jaw portion 170, they may be generally configured to have a handle end and a jaw end. In this regard, the hose clamp pliers 100 are described herein with respect to a longitudinal axis 102, as shown in
Opening and closing of the hose clamp pliers 100 may be accomplished by rotation of the first plier half 110 and second plier half 160 about the pivot member 150. In some embodiments, the pivot member 150 may be a separate element, such as a shaft, that is inserted through each of the first plier half 110 and the second plier half 160. For example, the pivot member 150 may be rotatable with respect to each of the first plier half 110 and the second plier half 160 such that neither plier half is rotationally constrained with respect to the pivot member 150. Alternatively, in some embodiments, the pivot member 150 may be fixed with respect to one of the plier halves. For example, in some embodiments, the pivot member 150 may be integrally formed with the first plier half 110 or the second plier half 160.
In some embodiments, the pivot member 150 may be adjustable with respect to one of the plier halves. For example, in the illustrated embodiment, the pivot member 150 has a fixed position (but is freely rotatable) with respect to the second plier half 160 but is held in a channel 116 in the first plier half 110. For example, the width of the pivot member 150 may be sized to fit within the channel 116 and allow the pivot member 150 to move along the length of the channel 116. To retain the pivot member 150 in the channel 116, the pivot member 150 may include a head that is larger than the width of the channel 116 so that the pivot member 150 cannot be removed from the channel 116 and the hose clamp pliers 100 are held together.
The use of the channel 116 allows the hose clamp pliers 100 to adjust between a narrow configuration and a wide configuration, in the manner of slip joint pliers. In the illustrated embodiment, when the pivot member 150 is at a first end 117 of the channel 116, as shown, the hose clamp pliers 100 are in the narrow configuration. In this configuration, the first plier half 110 and the second plier half 160 are held close to one another, such that the first jaw portion 120 abuts the second jaw portion 170 when the hose clamp pliers 100 are closed, as shown. When the pivot member 150 moves to the second end 118 of the channel 116, the hose clamp pliers 100 are placed in the wide configuration. In this configuration, the first jaw portion 120 can be further separated from the second jaw portion 170 in order to form a wider opening for engaging larger hose clamps or gripping larger items.
The longitudinal grooves described herein are referred to herein as “longitudinal” in that they are substantially aligned with the longitudinal axis 102 of the hose clamp pliers 100, rather than a transverse axis 108, as shown in
In some embodiments, the width of each longitudinal groove may be consistent over the length of the longitudinal groove. For example, in the illustrated embodiment, as shown in
Similarly, in some embodiments, the depth of each longitudinal groove may be consistent over the length of the longitudinal groove. For example, in some embodiments, the depth of each groove is consistent from the front end of the respective jaw portion to the point at which the longitudinal groove ends. In other embodiments, for example, the depth of the longitudinal grooves may taper, such as from a greater depth at the front end of the jaw portion to a shallow depth where the groove ends.
The longitudinal grooves may be spaced apart across the width of the respective jaw portion. For example, as shown in
The inner face of the jaw portions may be smooth or may include a texture. For example, the inner face may include ridges or a knurled texture to aid in gripping surfaces.
While the illustrated embodiment shows jaw portions with only two longitudinal grooves, in other embodiments, one or both of the jaw portions may include additional grooves. For example, in some embodiments, the first jaw portion may have one or more additional longitudinal grooves between the first longitudinal groove and the second longitudinal groove. Similarly, in some embodiments, the second jaw portion may also include additional longitudinal grooves between the third longitudinal groove and the fourth longitudinal groove. Moreover, the number of longitudinal grooves in the first jaw portion may be the same or different from the number of longitudinal grooves in the second jaw portion.
The angled direction of the second section 134 of the longitudinal groove 130 allows the hose clamp pliers 100 to maintain a positive engagement with a hose clamp tab throughout the range of operation of the hose clamp pliers 100 in opening a hose clamp. The term positive engagement refers to contact that exerts a force in a direction toward the interior of the jaws of the hose clamp pliers 100. Positive engagement by the hose clamp pliers 100 may be achieved because the second section 134 of the longitudinal groove 130 is angled inward throughout the opening range of the hose clamp pliers. Comparatively, because the first section 132 of the first longitudinal groove 130 is parallel to the longitudinal axis 102 when the hose clamp pliers 100 are closed, as soon as the hose clamp pliers 100 begin to open from the position shown in
In some embodiments of the hose clamp pliers, the first section of each longitudinal groove may be straight. For example, as shown in
Further, in some embodiments, the second section of each longitudinal groove may be straight. For example, as shown in
In some embodiments, the angle between the first section and second section of each longitudinal groove may be in a range of 20 to 40 degrees. For example, in some embodiments, the angle between the first section and second section of each groove may be about 30 degrees. The term about 30 degrees, as described herein, is 30 degrees+/−2 degrees. In other embodiments, the angle between the first section and second section of each groove may be in a range of 29 to 31 degrees. In some embodiments the angle between the first section and the second section in each of the longitudinal grooves is the same. In other embodiments, the angles may be different. For example, in some embodiments, the first and third longitudinal grooves may have first and second sections that are angled by a first amount while the second and fourth longitudinal grooves may have first and second sections that are angled by a different amount.
In some embodiments of the hose clamp pliers, the first longitudinal groove 130 and the second longitudinal groove 140 have the same shape. In other words, in some embodiments, the first longitudinal groove 130 and the second longitudinal groove 140 are identical. Further, in some embodiments, the third longitudinal groove and the fourth longitudinal groove may be mirror images of the first and second longitudinal grooves. In other embodiments, the longitudinal grooves may have different shapes.
In some embodiments, the longitudinal grooves may include a third section extending from the second section and having a circular configuration that curves toward the second jaw portion of the second plier half. For example, in the illustrated embodiment of
In some embodiments, the inner face of the first jaw portion may include a transverse groove that intersects the first and second longitudinal grooves. For example, as shown in
The transverse grooves may be beneficial in providing flexibility for using the hose clamp pliers to remove or install a hose clamp. For example, the hose clamp pliers may initially be used to engage the tabs of a hose clamp with the longitudinal grooves but then be reoriented to engage the hose clamp with the transverse grooves for further adjustment. Alternatively, the transverse grooves may be used first and the longitudinal grooves second, for example.
In some embodiments the first transverse groove may be perpendicular to the first longitudinal groove. For example, as shown in
The present disclosure also relates to a method of using hose clamp pliers.
