FIELD OF THE INVENTION [0001] This invention relates to hairstyling appliances, and more particularly, to a non-thermal hairstyling brush having a clamp that holds the hair in contact with the brush while the brush is rotated when drying and styling the hair. BACKGROUND [0002] Hairstyling in the past has been addressed by using a number of different implements such a curling irons, curling devices with clamps, various shapes of combs and brushes, and the like. In order to improve their effectiveness, thermal devices are sometimes used. Curling irons with clamps are an example. Use of non-thermal implements such as specially-shaped or designed combs or brushes may be used with applied heat from a hair dryer, for example. However, the prior art does not provide an effective hairstyling appliance that can be used easily and effectively for styling the hair while applying heat separately such as from a hair dryer. [0003] The present invention provides an ergonomically and functionally effective non-thermal hairstyling device which is useful in styling the hair while using a separate heat applying device such as a hair dryer. SUMMARY OF THE INVENTION [0004] Briefly, one embodiment of this invention comprises a hairstyling brush having an elongated handle, a brush affixed to a front end of the handle, with bristles extending radially outwardly from the brush, and a push button and spring-actuated clamp carried on the handle next to the brush. The clamp pivots through an angle between an open position for wrapping the hair around the brush, in an angular gap formed between the open clamp and the brush, and a closed position for overlying the brush and holding the hair in place on the brush. The clamp is actuated by a push button carried near a front portion of the handle. The push button is disposed in an internal space within the front position of the handle to contact a spring engaged with an internal portion of the push button. Finger pressure applied to the push button against the bias of the spring opens the clamp. The clamp is released to move under spring pressure to the closed position for holding the hair on the brush while rotating the brush. The user holds the brush in one hand while holding a hair dryer in the other hand, for drying and styling the hair, while the hair is in contact with the brush, held on the brush by the spring pressure of the clamp. [0005] The invention is ergonomically effective in holding the hair in close contact with the brush while the brush is easily and effectively rotated with one hand, without interference, while the other hand is used to hold the hair dryer. [0006] These and other aspects of the invention will be more fully understood by referring to the following detailed description and the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS [0007] FIG. 1 is an exploded side elevational view showing components of a non-thermal hairstyling device according to principles of this invention. [0008] FIG. 2 is a side elevational view showing a hair-clamping device in an angled open position. [0009] FIG. 3 is a side elevational view similar to FIG. 2 but showing the clamping device in a closed position. [0010] FIG. 4 is a top elevational view taken of line 4-4 of FIG. 3. [0011] FIG. 5 is a side elevational view taken on line 5-5 of FIG. 4 and showing a configuration of the hair-clamping device. DETAILED DESCRIPTION [0012] Referring to FIG. 1, a hairstyling device of this invention includes a cylindrical shaped and perforated tubular shell 10, and a brush 12 which, in assembly, is disposed inside the shell. An inner end cap section 14 is secured to an end of the shell for containing the brush inside the shell. An elongated handle section 16, in assembly, is disposed over the inner end cap 14 for attaching a front portion of the handle to a rear portion of the brush and shell assembly. A hair clamp 18, in assembly, overlies the brush and shell assembly and is pivotally secured to the end cap. A push button assembly 20 is located adjacent to a rear portion of the clamp and, in assembly, a portion of the push button is disposed in a recessed region 22 near the front end portion of the handle. [0013] The tubular shell is preferably made from metal to provide a somewhat rigid cylindrical shape. The shell is perforated with relatively large holes 22 spaced apart circumferentially in rows extending parallel to each other along the length of the shell. [0014] The brush 12 includes an axial rod 24 to which radially extending bristles 26 are secured. The bristles are arranged in groups with each group of bristles extending through a corresponding hole in the shell. The assembled arrangement of the brush and shell is best shown in FIGS. 2 and 3 which illustrate how the groups of bristles project radially outwardly through the vent holes in the cylindrical shell. The outer surface of the shell provides a firm base with outer portions of the bristles projecting free for use in styling the hair in the well-known manner. [0015] A front end cap 28 is secured to a front portion of the shell to close off the interior of the shell, as shown best in FIGS. 2 and 3. [0016] The inner end cap section 14 is one embodiment in which the brush is securely held in place and an internal support is provided for a spring that controls rotation of the hair clamp. An alternative embodiment is described below. The illustrated end cap section 14 has a cylindrical cap 30 at its front end which is secured to a rear portion of the shell to close off the interior of the shell in front of the handle 16. The end cap 14 also includes an elongated base 32 in the shape of a post which extends axially away from the brush toward a rear portion of the hairstyling device. In its assembled position, the end cap 30 aligns the base 32 of the end cap on the axis of the brush collinear with the rod 24 in the center of the brush. The end cap 30 has a pair of holes 34 aligned on a lateral axis perpendicular to the principal axis of the brush to provide a seat for one or more pivot pins as described below. [0017] The handle section 16 is preferably made of molded plastic material that includes a cylindrical front end cap 36 that opens toward the brush end of the hairstyling device. The handle section also includes an elongated hand-held section 38 which is formed integrally with the end cap 36 and which extends axially to the rear of the hairstyling device. The end portion of the hand-held section 38 tapers generally narrower toward the end of the hairstyling device away from the recessed region 22. The hand-held section accommodates the full width of the user's hand behind the recessed region 22 and the push button when the hairstyling device is used. [0018] The end cap 36 on the front of the handle section has an inside diameter greater than the inside diameter of the end cap 30 which engages the rear portion of the brush. In assembly, the end cap 36 fits over the end cap 30 in a tight friction lock to rigidly affix the handle section to the rear section of the brush. The front portion of the handle section 16 has a hollow area centered in the end cap 36 for receiving the post 32 of the inside end cap 30 when the handle section 16 is fitted over the inside end cap section 14. This securely fastens the inside end cap section 14 to the inside front portion of the handle section 16. [0019] The recessed region 22 on the front portion of the handle section opens upwardly to form a slotted area that receives the push button assembly 20. The push button assembly 20 includes a shell 40 that forms a lever arm for pivoting the hair clamp 18 about an axis between the brush end of the device and the handle. The push button shell 40 is rigidly affixed to or integrally formed with an end of the hair clamp 18. The hair clamp and the push button shell are preferably made of light weight metal. The push button assembly is adapted to be pushed downwardly into the recessed region 22 so as to raise the clamp to an angular open position shown in FIG. 2. The push button assembly is normally spring-actuated to be maintained in an at-rest or closed position shown in FIG. 3, holding the clamp in the closed position in which the clamp generally overlies the curved outer surface of the brush.
