Definitions

  • This invention relates to an umbrella, more particularly to a push-button operated extendable handle assembly for opening and closing a canopy of an umbrella.
  • a conventional umbrella generally has a handle mounted on a lower portion of a center shaft for gripping purposes.
  • the handle may be elongated in order to facilitate gripping, it will render the umbrella bulky, thereby resulting in inconvenient carrying and storage.
  • a shorter handle which makes the umbrella relatively compact is, however, inconvenient to grip.
  • a conventional umbrella capable of automatic opening and closing has an opening control unit and a closing control unit mounted on or in the vicinity of a handle to be operated for opening and closing the umbrella.
  • the user maybe confused as to which control unit he/she has to operate for closing or opening the umbrella.
  • the object of the present invention is to provide a push-button operated extendable handle assembly which has a variable length so as to be lengthened for facilitating gripping in a state of use, and to be shortened for facilitating carrying and storage in a state of non-use.
  • the push-button operated extendable handle assembly is for opening and closing a canopy of an umbrella.
  • the umbrella includes a tubular shaft having handle-side and top-side ends opposite to each other along an axis, and a runner sliding segment interposed between the handle-side and top-side ends; a runner sleeved on and slidable along the runner sliding segment between uppermost and lowermost positions which correspond to opened and closed positions of the canopy, respectively; a tubular plunger which is sleeved on the runner sliding segment, which extends from the runner along the axis to terminate at a tubular plunging end that is descendable with the runner towards the handle-side end when the runner slides toward the lowermost position, and which has a retaining hole; and a catch member which is disposed in the tubular shaft, and which has an actuated end in the runner sliding segment and proximate to the handle-side end, and a hook end that is opposite to the actuated end, and that extends out
  • the push-button operated extendable handle assembly comprises a primary shell member including a bottom mounting wall which is adapted to confront the handle-side end, and primary left and right walls which are spaced apart from each other in a transverse direction, and which extend to terminate at primary left and right upper edges, respectively, so as to define a stretching path therebetween, the primary left and right walls having left and right latching slots, respectively; a thrust transmitting member which includes a rammed end adapted to be thrusted by the tubular plunging end so as to displace from a lifted position, where the tubular plunging end is remote from the rammed end, to a depressed position, where the rammed end is engaged with the tubular plunging end, a depressing end that is opposite to the rammed end along the axis, and an actuating intermediate segment that descends with the depressing end along the stretching path; a first biasing member disposed to bias the rammed end towards the liftedposition; left and right latch members, each including a pushed end which
  • the umbrella 200 includes a tubular shaft 210 having handle-side and top-side ends opposite to each other along an axis (L), and a runner sliding segment interposed between the handle-side and top-side, ends, a runner 220 which is sleeved on and slidable along the runner sliding segment between uppermost and lowermost positions that are proximate to and distal from the top-side end, respectively, and that correspond to opened and closed positions of the canopy, respectively, a tubular plunger 221 which is sleeved on the runner sliding segment, which extends from the runner 220 along the axis (L) to terminate at a tubular plunging end 223 that is descendable with the runner 220 towards the handle-side end when the runner 220 slides toward the lowermost position,
  • the catch member 230 is configured such that the hook end 232 is urged by a biasing force to counteract the gravity of the runner 220 so as to hold the runner 220 in the uppermost position and such that, once the actuated end 231 is actuated against the biasing force, the tubular plunging end 223 descends towards the handle-side end.
  • the transmitting mechanism 240 includes a metal rod 250 connected to the hook end 232, a transmitting piece 260 pivotally connected to the metal rod 250, and a control piece 270 extending radially through the handle-side end to force the transmitting piece 260 to move along the axis (L).
  • the push-button operated extendable handle assembly 100 is shown to comprise a primary shell member 40, a transmitting mechanism 60, a secondary shell member 10, and upper and lower button units.
  • the primary shell member 40 includes a bottom mounting wall 41 having a periphery and confronting the handle-side end of the tubular shaft 210 along the axis (L), and a primary surrounding wall 42 which includes primary left and right walls 421 (see Fig. 3 ) that are spaced apart from each other in a transverse direction relative to the axis (L), and that extend from the periphery of the bottom mounting wall 41 to terminate at primary left and right upper edges 431, respectively, so as to define a stretching path therebetween and along the axis (L).
  • the primary left and right walls 421 have left and right latching slots 422, respectively, which are disposed between the primary left and right upper edges 431 and the periphery of the bottom mounting wall 41, respectively.
  • the left and right latching slots 422 extend towards the periphery of the bottom mounting wall 41 so as to provide left and right leeways to be described hereinafter.

  • the primary shell member 40 is movable relative to the secondary shell member 10 along the axis (L) between a non-stretchedposition (as shown in Fig. 3 ) which corresponds to the extended position of the latch ends 622, where the bottom mounting wall 41 is close to the lower end 122, and a stretched position (as shown in Fig. 6 ), where the bottom mounting wall 41 is remote from the lower end 122.
  • An abutment wall 15 is disposed securely at the lower end 122 such that the first biasing member 64 is disposed to abut against the depressing end 612 and the abutment wall 15 so as to bias the depressing end 612 towards the lifted position.
  • a second biasing member 50 is disposed to bias the primary shell member 40 to move from the non-stretched position to the stretched position.
  • the second biasing member 50 is disposed to surround and to be coaxial with the first biasing member 64 about the axis (L) such that the bottom mounting wall 41 of the primary shell member 40 can be moved away from the lower end 122 of the secondary shell member 10 by virtue of the biasing action of the second biasing member 50 when the rammed end 614 is moved to the lifted position.
  • the secondary shell member 10 further has a mounting segment (10a) disposed proximate to the lower end 122, and a manually operated segment (10b) interposed between the upper end 121 and the mounting segment (10a).
  • the mounting segment (10a) includes left and right mounting walls 127 (see Fig. 3 ) which are spaced apart from each other in the transverse direction to define a lower chamber that is communicated with the stretching path, and that accommodates the left and right latch members 62, and which confront the primary left and right walls 421 in the transverse direction, respectively.
  • the left and right mounting walls 127 have left and right bores 1271 which extend therethrough respectively to be communicated with the lower chamber, and which, when the rammed end 614 is in the depressed position, are registered with the left and right latching slots 422, respectively, to permit the latch ends 622 to be placed in the extended position.
  • the manually operated segment (10b) includes front and rear mounting walls 128 (see Fig. 2 ) which are diametrically spaced apart from each other relative to the axis (L) to define an upper chamber that surrounds the runner sliding segment of the tubular shaft 210, and that accommodates the tubular plunger 221 when the runner 220 is in the lowermost position.
  • the rear mounting wall 128 has upper and lower mount regions (128a,128b) that are proximate to and distal from the upper end 121, respectively.
  • the front mounting wall 128 has upper and lower access openings 123, 124 that permit access to the upper and lower mount regions (128a,128b) radially and respectively. In this embodiment, the upper and lower access openings 123,124 are communicated with each other.
  • the upper button unit includes a retaining member 70, an upper pushing member 20, and an upper biasing member 23.
  • the retaining member 70 is disposed to be movable radially between an engaging position (as shown in Fig. 2 ), where the retaining member 70 engages the retaining hole 222 in the tubular plunger 221 in the lowermost position, and a disengaging position, where the retaining member 70 retreats to the upper mount region (128a) to be disengaged from the retaining hole 222.
  • the upper pushing member 20 has an upper push button 21 which is fitted into the upper access opening 123, and which is movable radially towards the upper mount region (128a), and an upper actuating end 22 which is moved with the upper push button 21 to bring the retaining member 70 into the disengaging position.
  • the upper pushing member 20 is integrally formed with the retaining member 70.
  • the upper biasing member 23 is disposed to bias the upper push button 21 away from the upper mount region (108a).
  • the lower button unit includes a lower pushing member 30 and a lower biasing member 33.
  • the lower pushing member 30 has a lower push button 31 which is fitted into the lower access opening 124, and which is adapted to actuate the actuated end 231 of the catch member 230 through the transmitting mechanism 240 in a known manner so as to release the tubular plunging end 223 from the catch member 230 when manually pushed radially towards the lower mount region (128b), and a lower actuating end 32 which is disposed opposite to the lower push button 31 in terms of the axis (L), and which is disposed to be moved with the lower push button 31.
  • the lower biasing member 33 is disposed to bias the lower push button 31 away from the lower mount region (108b).
  • the lower pushing member 30 is integrally formed with the upper pushing member 20 and is made of an elastomeric material such that the upper and lower push buttons 21,31 can be independently manipulated.
  • the mounting segment (10a) of the secondary shell member 10 has a concaved keyway 125 which extends towards the lower end 122 to terminate at upper and lower limit regions.
  • the primary shell member 40 has a key 43 which extends transversely to the axis (L) to be slidably engaged in the keyway 125, thereby guiding the bottom mounting wall 41 to move relative to the lower end 122 until the key 43 reaches one of the upper and lower limit regions.
  • the retaining member 70 When the push-button operated extendable handle assembly of this invention is in the state shown in Figs. 2 to 4 , the retaining member 70 is in the engaging position, i.e. the retaining member 70 engages the retaining hole 222, so as to hold the rammed end 614 in the depressed position against a biasing action of the first biasing member 64, thereby placing the pushed ends 621 of the latch members 62 in the heavily pressed position.
  • the primary shell member 40 is in the non-stretched position, and the lower pushing member 30 is retreated into the primary shell member 40 to prevent an undesired operation.
  • the user pushes the lower push button 31 to release the runner 220 from the catch member 230 so as to permit the runner 220 to move to the lowermost position such that the tubular plunger 221 is moved into the upper chamber in the secondary shell member 10 to place the retaining member 70 in the retaining hole 222.
  • the rammed end 614 is forced by the tubular plunging end 223 to the depressed position, and the latch ends 622 are moved to the retracted position, i.e. the latch ends 622 are inserted into the latching slots 422 so as to hold the primary shell member 40 in the non-stretched position.
  • the leeways provided by the latching slots 422 facilitate insertion and engagement of the latch ends 622 therein.
  • the primary shell member 40 when the runner 220 is in the lowermost position corresponding the closed position of the canopy of the umbrella 200, the primary shell member 40 is in the non-stretched position so that the assembly 100 has a relatively small length, thereby making the umbrella 200 more compact for carrying and storage. Moreover, the lower push button 31 can be retreated into the primary shell member 40 to prevent undesired operation thereof. When the runner 220 is in the uppermost position corresponding the opened position of the canopy of the umbrella 200, the primary shell member 40 is in the stretched position so that the assembly 100 has a relatively large length, thereby lengthening the umbrella 200 to facilitate gripping of the assembly 100.
