## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an apparatus for selectively attaching a first object to a second object in a desired orientation. In particular, the present invention relates to an apparatus for attaching a first object, e.g., a headlamp to a second object, e.g., a bicycle handlebar in a manner that the first object can be located in a desired orientation with respect to the second object.
2. Description of the Related Art
A bicycle generally has a headlamp to provide illumination when required. U.S. Pat. No. 5,735,441 to Fujimoto issued on Apr. 7, 1998 discloses an apparatus for attaching two-wheeled vehicle parts allowing adjustment of the attachment angle. The apparatus comprises an attachment part 1 attached to a handle 27 of a bicycle 25, an attachment part 2 fixed on a head lamp 29 of the bicycle 25, and an attachment part 3 connecting the first and second attachment parts 1 and 2. The attachment parts 1 and 2 rotate relative to each other. The attachment parts 2 and 3 are detachable from each other by sliding of rail members 7a and 7b with grooves 17a and 17b. However, the head lamp 29 can only be adjusted in the horizontal position; namely, adjustment of the head lamp 29 in the vertical position cannot be achieved.
U.S. Pat. No. 6,264,351 to Taylor et al. issued on Jul. 24, 2001 discloses a convertible orientation bicycle lamp. The lamp holding member is capable of altering its orientation with regard to a base member such that the orientation of the lamp holding member vis-a-vis the clamping member may be altered. However, the lamps can only be pivoted about a fixed axis and thus have a limited adjustment in only one of the vertical plane and the horizontal plane. When adjustment of the lamps in an orthogonal plane is required, the whole clamp assembly to which the lamps are attached must be detached from the bicycle handlebar and then reattached to the handlebar in a different orientation.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an apparatus for attaching a first object to a second object in a manner that the first object can be located in a desired orientation with respect to the second object.
The apparatus comprises an engaging member detachably mounted to the second object, e.g., a bicycle handlebar. The apparatus further comprises a fixing member to which the first object, e.g., a headlamp of a bicycle is attached. The headlamp can be mounted to the engaging member in a desired orientation. The engaging member remains on the handlebar when reattaching the headlamp to the engaging member.
In an embodiment of the invention, the engaging member comprises a polygonal member having a plurality of pairs of parallel sides. The fixing member to which the headlamp is mounted can be selectively engaged with one of the plurality pairs of parallel sides. The selective engagement between the fixing member and the parallel sides of the engaging member allows the headlamp to be located in a position providing optimal illumination.
In an embodiment of the invention, the first object is a cellular phone bag such that the user may securely put it on the handlebar while cycling. The selective engagement between the fixing member and the parallel sides of the engaging member allows the cellular phone to be located in an easy-to-access position.
Adjustment of the position of the first object (i.e., the cellular phone bag or the headlamp) can be achieved easily without detaching the whole apparatus from the handlebar of the bicycle.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1 through 3, an attaching apparatus in accordance with the present invention generally comprises a fixing member 10 to which a first object, e.g., a cellular phone bag or a bicycle headlamp is attached. The attaching apparatus further comprises an engaging member 20 to which the fixing member 10 is releasably engaged. Further, the attaching apparatus comprises an attaching member 30 for attaching the engaging member 20 to a second object, e.g., a bicycle handlebar.
Referring to FIGS. 2 and 2A, the fixing member 10 comprises a first side 11 and a second side 12 opposite to the first side. A substantially U-shaped elastic member 13 has a first limb 13a attached to the second side 12 of the fixing member 10 and a second limb 13b to which a first side 141 of a clamp member 14 is attached. The clamp member 14 comprises a press end 144 and a clamp end 143 opposite to the press end 144. The clamp end 143 of the clamp member 14 is biased by the elastic member 13 to engage with the second side 12 of the fixing member 10. As illustrated in FIG. 2A, when the press end 144 is pressed, the clamp end 143 is moved away from the fixing member 10. A cellular phone bag 40 can be securely attached to the first side 11 of the fixing member 10, as illustrated in FIG. 5. The fixing member 10 can be attached to a belt 41 worn on a user by means of using the clamp member 14. Namely, the press end 144 of the clamp member 14 is pressed to allow insertion of the belt 41 into a space 145 (FIG. 2A) between the clamp end 143 of the clamp member 14 and the second side 12 of the fixing member 10. The press end 144 of the clamp member 14 is then released, and the cellular phone bag 40 is securely attached to the belt 41 under the action of the elastic member 13, as shown in FIG. 6.
Turning back to FIGS. 2 and 2A, the clamp member 14 further comprises a groove 161 defined by two parallel ribs 15 projecting from a second side 142 of the clamp member 14. The second side 142 of the clamp member 14 forms a bottom wall that defines the groove 161. The groove 161 includes an opening 16 in the clamp end 143 of the clamp member 14 and terminates at an end wall 162 facing the opening 16. The press end 144 of the clamp member 14 further comprises a U-shaped slot 17, thereby forming a resilient tongue 18. In this embodiment, the resilient tongue 18 comprises a first end 181 integrally formed with the bottom wall defining the groove 161 and a free second end 182. A protrusion 183 is formed on the bottom wall (i.e., the second side 142 of the clamp member 14).
The engaging member 20 comprises a seat 21 having an arcuate bottom side 211 for embracing a portion of a bicycle handlebar. The seat 21 of the engaging member 20 further comprises an upper side 22 and a passage 212 between the upper side 22 and the arcuate bottom side 211. An attachment member 30 is provided to attach the engaging member 20 to the bicycle handlebar. Referring to FIGS. 3, 3A, and 3B, in this embodiment, the attachment member 30 comprises a fastening strap 31 having a first end to which a sleeve 34 is securely attached and a second end that is secured in place after passing through the passage 212 of the seat 21 and a gap 36 between the first end of the fastening strap 31 and the sleeve 34. The fastening strap 31 includes a plurality of retaining grooves 32 in an outer periphery thereof A screw 33 is rotatably received in the sleeve 34 and has a threaded portion 35 engaged with several retaining grooves 32 of the fastening strap 31. When the screw 33 is turned in a direction, the second end of the fastening strap 31 is moved away from the screw 33 and thus tightly clamps around the bicycle handlebar 42 (FIG. 7). Thus, the engaging member 20 is securely attached to the bicycle handlebar 42. When the screw 33 is turned in a reverse direction, the second end of the fastening strap 31 is moved toward the screw 33 such that the fastening strap 31 is loosened. Thereafter, the engaging member 20 together with the attachment member 30 can be detached from the bicycle handlebar 42. Of course, the engaging member 20 can be detached from the attachment member 30 when required.
The engaging member 20 further comprises a polygonal member 23 and a neck 24 between the upper side 22 of the seat 21 and the polygonal member 23. The polygonal member 23 comprises a polygonal peripheral wall 231 defined by a plurality of pairs of parallel sides. In this embodiment, the polygonal peripheral wall 231 is square and thus has two pairs of parallel sides 203 and 204, 205 and 206. The polygonal peripheral wall 231 extends above an upper face 232 of the polygonal member 23. A positioning groove 233 is defined in the upper face 232 of the polygonal member 23 and located inside the polygonal peripheral wall 231. Preferably, the positioning groove 233 is polygonal and extends along the polygonal peripheral wall 231.
Referring to FIGS. 2 and 3C, the fixing member 10 may be mounted to the engaging member 20 by means of moving the fixing member 10 along an axis 201 orthogonal to the sides 205 and 206 with the opening 16 of the clamp member 14 facing the polygonal member 23. The two sides 203 and 204 of the polygonal peripheral wall 231 slide along the groove 161 of the clamp member 14 when the member 14 slides relative to the polygonal member 23. The protrusion 183 of the resilient tongue 18 slides across the upper face 232 of the polygonal member 23 while the resilient tongue 18 deflects upward by means of direct contact with the upper face 232. The sliding movement of the clamp member 14 continues until the protrusion 183 of the resilient tongue 18 is securely engaged in the positioning groove 233 of the polygonal member 23 under the resilience of the resilient tongue 18. It is noted that the protrusion 183 of the tongue 18 has an inclined face 184 (FIG. 2A) facing the opening 16 of the groove 161 such that the disengagement of the protrusion 183 of the tongue 18 from the positioning groove 233 of the polygonal member 23 in the reverse direction is prevented, best shown in FIG. 3. The positioning groove 233 is so configured to cooperate with the protrusion 183 of the resilient tongue 18. The polygonal peripheral wall 231 also assists in retaining of the protrusion 183 of the resilient tongue 18. In addition, due to the polygonal configuration of the polygonal peripheral wall 231, relative rotation between the fixing member 10 and the engaging member 20 is prevented. When detaching the fixing member 10 from the engaging member 20 is required, the press end 144 of the clamp member 14 is pressed to disengage the protrusion 183 from the positioning groove 233 of the polygonal member 23, and the fixing member 10 is slid away from the engaging member 20 in a direction reverse to the engaging direction.
Referring to FIGS. 2 and 4, the fixing member 10 may be mounted to the engaging member 20 by means of moving the fixing member 10 along an axis 202 orthogonal to the axis 201. The engagement and disengagement between the fixing member 10 and the engaging member 20 along the axis 202 are identical to those along the axis 201 except that the fixing member 10 is located in an orientation that is 90° away from the previous orientation relative to the engaging member 20.
Referring to FIGS. 5 and 6, as mentioned above, a cellular phone bag 40 can be securely attached to the first side 11 of the fixing member 10 and carried by a belt 41 worn on a user. The engaging member 20 is securely attached to a bicycle handlebar 42 by the attaching member 30. When riding a bicycle, the fixing member 10 is disengaged from the belt 41 and then engaged with the engaging member 20 in a desired orientation such that the cellular phone can be located in an easy-to-access position, best shown in FIG. 7.
Referring to FIGS. 8 and 9, the attaching member can be a quick release 30′ having a first end securely attached to the engaging member 20 and a second end releasably engaged with the bicycle handlebar 42. At least one headlamp 50 can be attached to the fixing member 10, which is engaged with the engaging member 20 in a desired orientation to provide optimal illumination. It is noted that the headlamps 50 in FIG. 8 are located in an orientation that is 90° away from that in FIG. 9.
The polygonal member 23 may be hexagonal for providing three orientation options for attaching the fixing member 10 to the engaging member 20. Of course, the polygonal member 23 may include eight, ten, or more sides to provide more options.
It is noted that the engaging member 20 remains on the handlebar 42 when reattaching the headlamp 50 or the cellular phone bag 40 to the engaging member 20.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the invention as hereinafter claimed.
